Description

Signal processing method and related equipment

The embodiment of this application requires the priority of the Chinese patent application filed on March 31, 2020 with the application number 202010245337.4 and the title of the invention "signal processing method and related equipment", the entire content of which is incorporated into the embodiment of this application by reference .

Technical field

The embodiments of the present application relate to the field of computer technology, and in particular, to a signal processing method and related equipment.

Background technique

With the rapid development of automotive electronics technology, the sensor signals collected in the sensor unit on the vehicle can be processed into a message according to certain rules, and then the message is reported to the server, and the server provides intelligent services for the vehicle based on the message. For example, the message may be a message for the state of a car window, and the message may be used to indicate whether the car window is open, or the percentage of open. Among them, the message includes multiple message parameters, and processing the sensor signal into a message according to certain rules means: determining the parameter value of each message parameter in the message according to the signal value of the sensor signal.

In the related art, for each of the multiple messages, the process of how to determine the parameter value of each message parameter in the message based on the signal value of the sensor signal is written as a code in a hard-coded manner to obtain the processing function of the message. For example, for a message for the state of a car window, the processing function indicates that when the signal value of sensor signal 1 satisfies condition 1, the signal value of sensor signal 2 satisfies condition 2, the value of the message parameter "percentage" in the message is 50 %, when the signal value of sensor signal 1 satisfies condition 3 and the signal value of sensor signal 2 satisfies condition 4, the value of the message parameter "open or not" in the message is "unopened". That is, the message processing function is used to indicate the corresponding parameter value of the message parameter when the signal value of each sensor signal meets different conditions. Store messages and message processing functions in the message processing mapping table. When the signal values of multiple sensor signals for a certain message are acquired, the processing function of the message is acquired from the message processing mapping table. By processing the signal values of multiple sensor signals based on the acquired processing function, the parameter value of each message parameter included in the message can be determined.

The processing function of each message in the above message processing mapping table needs to be written in a hard-coded manner. If a certain logic in the processing function changes, the code of the processing function of the message needs to be rewritten, which results in a large workload of manual coding.

Summary of the invention

The embodiments of the present application provide a signal processing method and related equipment, which can reduce the workload of manual encoding codes in the process of generating messages. The technical solution is as follows:

In the first aspect, a signal processing method is provided. In this method, a signal data packet is obtained, and the signal data packet includes the identifier of the first message and a plurality of signal values, and the plurality of signal values correspond to a plurality of sensor signals; this is based on the rule grammar and the first rule configuration file. The multiple signal values are processed to obtain the parameter value of each message parameter in the first message.

Among them, the first rule configuration file refers to a file that indicates the generation rule of the first message based on the rule grammar, and the generation rule of the first message is used to indicate how to convert the signal values of the multiple sensor signals into the parameters of each message. The parameter value. Based on the setting of the first rule configuration file, the technical solution provided by the embodiment of the present application has at least the following technical effects:

(1) In traditional technology, the processing function of writing a message is hard-coded, which is equivalent to hard-coding various possible value combinations of the sensor signal, resulting in a high degree of similarity in each part of the code of the written processing function, which in turn leads to the code The readability is very poor. The embodiment of the present application extends a rule grammar, based on which the generation rules of each message can be standardized in advance to obtain the rule configuration file of the message. That is, the embodiment of the present application only needs to use the rule configuration file to indicate the generation rule of the message, which avoids the need to write the code in a hard-coding manner, thereby eliminating the problem of poor readability of the code in the hard-coding.

(2) Once the message processing function written by hard coding in the traditional technology is released, the generation rule of the message will not be changed. If the message generation rules are changed, the processing function needs to be rewritten and republished. However, in the embodiment of the present application, since the message generation rule is indicated by the rule configuration file, when the generation rule of a certain message changes, only the rule configuration file of the message needs to be adaptively modified. , There is no need to regenerate the entire rule configuration file. In this way, it is possible to avoid writing the code of the generation rules by hard coding, which leads to the problem of rewriting all the codes when updating the generation rules.

(3) Compile the processing function of each message according to the hard-coded method in the traditional technology. Because there is no unified vehicle regulation requirement for the on-board signal data collection of each car factory, the signal processing rules of each car factory are also different, so it is targeted for each car factory. The reusability of the code of the generated rules for the message of the collected signal is also relatively poor. This leads to the need to maintain different message generation rule codes for different depots, which increases the maintenance cost of the message generation rule codes. However, in the embodiment of the present application, a unified rule grammar is provided, and the conversion of the rule configuration file to the generation rule can be completed only based on the unified rule grammar, so as to meet the differentiated demands of the vehicle factory for data collection. Therefore, different car manufacturers can load the relevant modules of the signal processing method provided in the embodiments of the application on the vehicle to realize signal processing. In this way, data collection functions of multiple manufacturers can be shared and reused, thereby reducing the difficulty and difficulty of product software implementation. Workload.

Based on the method provided in the first aspect, in a possible implementation manner, the first rule configuration file indicates the generation rule of the first message in a key-value manner based on the rule grammar. In this scenario, the rule grammar is used to indicate the semantics of each key in the first rule configuration file.

For any message parameter in the first message, each possible parameter value of the message parameter and the condition that the sensor signal corresponding to each possible parameter value needs to meet can be indicated through the above-mentioned action key and condition key. Thereby, it is realized that the first rule configuration file can indicate the generation rule of the first message, so as to solve the technical problem caused by the hard coding method.

Based on the method provided in the first aspect, in a possible implementation manner, for the first sensor signal of the plurality of sensor signals, the value corresponding to the first condition key includes a triplet corresponding to the first sensor signal , The triple includes a logical operator used to indicate a logical operation relationship, an identifier of the first sensor signal, and a reference signal value.

Since it corresponds to any message parameter, the conditions that the sensor signal corresponding to each possible parameter value of the message parameter needs to meet can be represented by the above triplet. That is, in the embodiments of the present application, through the definition of the logical operation relationship, it is possible to store the complex generation rules in the rule configuration file in a key-value manner, so as to achieve the technical effects provided by the above-mentioned first aspect.

Since the embodiment of this application indicates the generation rule of the message through the rule configuration file, when the generation rule of a certain message is changed, only the rule configuration file of the message needs to be adaptively modified, and there is no need to regenerate it. The entire rule configuration file. In this way, it is possible to avoid writing the code of the generation rules by hard coding, which leads to the problem of rewriting all the codes when updating the generation rules.

Based on the method provided in the first aspect, in a possible implementation manner, the first rule configuration file indicates the generation rule of the first message in a key-value manner based on the rule grammar. In this scenario, the implementation of updating the first rule configuration file according to the changed content may be: according to the changed content, the key to be modified in the first rule configuration file is determined based on the rule syntax; and the key corresponding to the determined key according to the changed content The value is modified.

Detailed ways

In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following further describes the embodiments of the present application in detail with reference to the accompanying drawings.

Before explaining the signal processing method provided in the embodiments of the present application, the application scenarios involved in the embodiments of the present application will be introduced first.

With the rapid development of automotive electronics, the current realization of vehicle functions and manufacturer services is increasingly dependent on network platforms. For example, in an autonomous driving scenario, the vehicle needs to collect surrounding environmental information and other data, and report the collected data to the network platform, which will plan the route of the vehicle based on the data. Among them, when the car factory remotely collects or controls the on-board electronic control unit (ECU) signal, it needs to perform the regular conversion processing of the signal value, that is, the signal value of the collected sensor signal is converted into a message according to a certain rule, and then sent to The network platform reports the message so that the network platform can control the vehicle based on the reported message. For example, the smart terminal (telematics BOX, T-BOX) on the vehicle collects the signal value of each sensor on the vehicle, and it is required to process the message into a message according to the set signal conversion rules, and then report the message to the application center of the car factory. Based on the message, the application center of the car factory performs remote control of the car such as flashing lights and whistle. Among them, the vehicle-mounted intelligent terminal is mainly used for communication between the vehicle and the Internet of Vehicles service platform.

The above processing rules for the collected signal values are also the generation rules for messages. Currently, there is no uniform vehicle regulation requirement for the message generation rules, and each vehicle manufacturer may implement it differently. In order to facilitate the subsequent program elaboration, a sample generation rule of a message is introduced. Table 1 shows the definition of each parameter included in the message.

As shown in Table 1, the identifier of the message is "VAL_WINDOWFIRSTROWRIGHT_IND", indicating that the message is for the window on the right side of the first row of the vehicle. The message includes three message parameters, namely the first message parameter, the second message parameter, and the third message parameter. Among them, the first message parameter is used to indicate whether the window is installed, the second message parameter is used to indicate whether the window is open, and the third message parameter is used to indicate the open percentage of the window. Therefore, the first message parameter may also be referred to as a state parameter, the second message parameter may also be referred to as an open parameter, and the third message parameter may also be referred to as an open percentage parameter.

Table 1

As shown in Table 1, the parameter value range of the first message parameter includes three value ranges: valid, invalid, and notsend. Among them, valid is used to indicate that a window is currently installed, invalid is used to indicate that a window is not currently installed, and notsend is used to indicate that the parameter value of the message parameter is not currently sent. The parameter value range of the second message parameter includes two values: true and false. Among them, true (yes) is used to indicate that the current window is open. false (no) is used to indicate that it is currently closed. The parameter value of the third message parameter ranges from 0 to 100, which are respectively used to indicate the current open ratio of the window. For example, the parameter value of the third message parameter is 50, which indicates that the window is currently opened by 50%.

In the embodiment of the present application, the message generation rule refers to a rule for indicating how to determine the parameter value of the message parameter based on the signal value of the sensor signal. The following uses the first message parameter in Table 1 as an example to illustrate the generation rule of the message.

Table 2

Take the third line in Table 2 above as an example to illustrate how to determine the parameter value of the first message parameter according to the signal value of the sensor signal. As shown in the third row, when the signal value of the first sensor signal is 2, the signal value of the second sensor signal is within the valid interval [0,200], and the signal value of the third sensor signal is within the valid interval [0,1] Inside, the signal value of the fourth sensor signal is 1, and the signal value of the fifth sensor signal, the sixth sensor signal, and the seventh sensor signal does not matter what value it takes (DC in Table 2 is used to indicate whether the sensor signal takes the sum value) , The parameter values of the first message parameter are all valid. Each row in the fourth row to the eighth row in Table 2 corresponds to a parameter value of the first message parameter and the conditions to be met by the signal value of each sensor signal, which will not be explained one by one here.

Through the above Table 1 and Table 2, when the signal value of each sensor is obtained, the parameter value of each message parameter in the message can be determined, and then the parameter value of each message parameter in the message can be reported. The signal processing method provided by the embodiment of the present application is applied to the above-mentioned scenario in which the parameter value of each message parameter in the message is determined based on the signal value of the sensor signal. These scenarios are not limited to scenarios where messages are determined based on sensor signals on the vehicle, but also include any other scenarios where messages need to be determined based on sensor signals.

FIG. 1 is a schematic structural diagram of a signal processing system provided by an embodiment of the present application. As shown in FIG. 1, the system 100 includes a microcontroller unit (microcontroller Unit, MCU) 101 and a signal processing unit 102. The MCU 101 and the signal processing unit 102 are connected for communication.

The aforementioned MCU 101 and signal processing unit 102 may be deployed on a vehicle. In addition, an in-vehicle signal collection application can also be deployed on the vehicle, so that the signal processing unit can implement the signal processing method provided in the embodiment of the present application through a server corresponding to the in-vehicle signal collection application. That is, the signal processing method provided by the embodiment of the present application can be directly executed by the signal processing unit. In this scenario, the signal processing unit needs to have relatively large data processing capabilities. The signal processing method provided in the embodiments of the present application may also be delivered by the signal processing unit to the server corresponding to the vehicle-mounted signal acquisition application for processing, so as to reduce the data processing pressure of the signal processing unit.

The aforementioned MCU 101 is used to collect signal values of various sensors deployed on the vehicle, and send signal data packets to the signal processing unit 102 in units of messages. The MCU 101 sending a signal data packet in a message unit means that the MUC 101 determines the signal value of each sensor signal required to generate a certain message and the identifier of the message together as a data packet, and sends it to the signal processing unit 102. For example, for the first message and the second message, the MCU 101 may send the first signal data packet and the second signal data packet to the signal processing unit 102 respectively. Wherein, the first signal data packet includes the identifier of the first message and the signal value of each sensor signal required to generate the first message. The second signal data packet includes the identifier of the second message and the signal value of each sensor signal required to generate the second message. The first message and the second message can be any two messages.

After receiving the signal data packet, the signal processing unit 102 determines the message indicated by the message identifier included in the signal data packet based on the signal value of each sensor signal included in the signal data packet through the signal processing method provided in the embodiment of the present application The parameter value of each message parameter in.

After the signal processing unit 102 determines the parameter value of each message parameter in a certain message, it can report the parameter value of each message parameter in the message to the data collection server 103 in FIG. 1. The data collection server 103 performs operations such as intelligent control of the vehicle based on the parameter value of each message parameter in the message.

The foregoing takes the signal processing unit 102 to implement the method provided in the embodiment of the application as an example to illustrate the system architecture of the communication network. When the method provided in the embodiment of the application is applied, it can also be directly collected by the vehicle-mounted signal deployed on the vehicle or other terminal. It is used to implement the signal processing method provided in the embodiment of the present application online, which is not specifically limited in the embodiment of the present application.

The MCU 101 in FIG. 1 can be connected to various sensors deployed on the vehicle through a communication bus, so as to collect the signal value of each sensor. The signal processing unit 102 in FIG. 1 is also connected to the communication bus of the vehicle to realize the connection between the MCU 101 and the signal processing unit 102. In addition, the data collection server 103 may be an independent server or a cluster server, which is not specifically limited in the embodiment of the present application.

In addition, FIG. 1 is only used to illustrate a possible application system of the embodiment of the present application. The signal processing method provided in the embodiment of the present application can also be applied to other systems that need to convert sensor signals into messages. The embodiment of the present application There is no specific restriction on this.

The signal processing method provided by the embodiment of the present application will be explained below.

FIG. 2 is a flowchart of a signal processing method provided by an embodiment of the present application, and the method is applied to the signal processing unit shown in FIG. 1. As shown in Figure 2, the method includes the following steps:

Step 201: The signal processing unit obtains a signal data packet, the signal data packet includes an identifier of the first message and a plurality of signal values, and the plurality of signal values correspond to a plurality of sensor signals.

As shown in Figure 1, the signal processing unit can receive signal data packets sent by the MCU. Based on the explanation of the system shown in Figure 1, it can be known that the MCU has processed the collected sensor signals in units of messages in advance. Therefore, the signal data packet received by the information processing server includes the identifier of the message currently to be processed, and determines the The signal value of each sensor signal required by the message.

For example, the identifier of the first message is "VAL_WINDOWFIRSTROWRIGHT_IND", which indicates that the first message is the message for the window on the right side of the first row of the vehicle shown in Table 1 above. At this time, the signal data packet includes the signal value of each sensor signal required to determine the parameter value of the three message parameters shown in Table 1. The multiple signal values may include the signal values of the seven sensor signals shown in Table 2 to determine the first message parameter in Table 1.

In the embodiments of the present application, in order to avoid the need to hard-code the generation rules of each message to write code, the generation rules of each message are stored in the form of a rule configuration file in advance. In order to facilitate the subsequent description, the rule configuration file provided in the embodiment of the present application will be explained here first. Taking the first message as an example, the rule configuration files of other messages can refer to the first message. In addition, for ease of description, the rule configuration file of the first message is referred to as the first rule configuration file.

The first rule configuration file refers to a file that indicates the generation rule of the first message based on the rule grammar. The generation rule of the first message is used to indicate how to convert the signal values of multiple sensor signals into the parameters of each message parameter in the first message. value.

From this, it can be seen that the embodiment of the present application extends a rule grammar, and based on the rule grammar, the generation rules of each message can be standardized in advance to obtain the rule configuration file of the message. So that in the subsequent process of generating messages, the rule configuration file can be parsed only based on the rule grammar, so as to determine the parameter value of each message parameter based on the generation rule indicated in the rule file. In this way, even if the message generation rule changes in the future, only the corresponding rule configuration file needs to be changed, and the entire rule configuration file does not need to be recompiled. In this way, it is possible to avoid writing the code of the generation rules by hard coding, which leads to the problem of rewriting all the codes when updating the generation rules.

In a possible implementation manner, the first rule configuration file indicates the generation rule of the first message in a key-value manner based on the rule grammar. In this scenario, the rule grammar is used to indicate the semantics of each key in the first rule configuration file. That is, the first rule configuration file stores the generation rule of the first message by key value. In this way, if the generation rule of the message changes, you only need to change the value of some keys in the corresponding rule configuration file. Yes, there is no need to rewrite the entire rule configuration file.

Because the first rule configuration file refers to a file that stores the generation rule of the first message in a key-value manner based on the rule grammar, and the generation rule of the first message is used to indicate how to determine each of the first messages based on the signal values of multiple sensor signals The parameter value of the message parameter. Therefore, in a possible implementation manner, for the first message parameter in the first message, the first rule configuration file includes multiple condition keys corresponding to the first message parameter, and multiple The condition key corresponds to multiple action keys one by one. Wherein, the first message parameter is one of the message parameters of the first message.

The value corresponding to the first condition key in the multiple condition keys is used to indicate a condition that the signal values of the multiple sensor signals need to meet, and the first condition key is one of the multiple condition keys. The value corresponding to the first action key is used to indicate the parameter value of the first message parameter when the signal values of the multiple sensor signals meet the condition indicated by the value corresponding to the first condition key. The first action key is an action key corresponding to the first condition key.

For example, take the parameter value of the first message parameter indicated in the third row of Table 2 as an example. At this time, in the first rule configuration file, the first condition key is used to indicate each sensor in the third row of Table 2. The value range that the signal value of the signal needs to meet. The first action key corresponding to the first condition key is used to indicate that the parameter value of the first message parameter in the third row of Table 2 is "valid".

For any message parameter in the first message, through these multiple condition keys and one-to-one corresponding multiple action keys, each possible value of the message parameter and the signal of the sensor signal corresponding to each possible value can be known The condition that the value needs to meet.

In addition, for any condition key, the value of the condition key is used to indicate the conditions that each sensor signal needs to meet. Therefore, the value range of the signal value of each sensor signal needs to be stored in the value of the condition key. Therefore, in a possible implementation manner, for the first sensor signal of the plurality of sensor signals, the value corresponding to the first condition key includes a triplet corresponding to the first sensor signal, and the triplet includes For indicating the logical operator of the logical operation relationship, the identification of the first sensor signal, and the reference signal value. The value range of the signal value of the first sensor signal can be indicated through the triplet.

The foregoing logical operation relations may include various logical operation relations such as equal, greater than, greater than or equal to, less than, less than or equal to.

In addition, because the rule configuration file is stored in the key-value manner, the above-mentioned triples can also continue to be represented in the key-value manner, that is, in the embodiment of the present application, the value of the key can continue to be embedded A set of key-value pairs to achieve an accurate description of the message generation rules. For example, the above-mentioned triples can also be described in terms of key values. At this time, the keys included in the triples are the logical operators used to indicate the logical operation relationship, and the values of the keys included in the triples That is, the identification of the first sensor signal and the reference signal value.

Take the parameter value of the indicated first message parameter shown in the third row of Table 2 as an example for description. Fig. 3 is a schematic diagram of condition keys and action keys in a rule configuration file provided by an embodiment of the present application. As shown in Figure 3, the value of the condition key "CONDITION" includes six triples, namely "EQUAL:{LVA:EPS-Lenkerposition, RVA: 2}" and "GTE:{LVA:FT-FH-Oeffnung, RVA: 0}", "LTE:{LVA:FT-FH-Oeffnung, RVA:200}", "GTE:{LVA:FT-FH-Fang, RVA: 0}", "LTE:{LVA:FT- FH-Fang, RVA: 1}", "EQUAL:{LVA:FT-FH-normiert, RVA: 1}".

In the above triplet, "EQUAL", "GTE", and "LTE" are three logical operators respectively. The three logical operation relationships indicated by these three logical operators are "equal to", "greater than or equal to", and " less than or equal to". In addition, the RVA in the above triple is used to indicate that the following information is placed on the right side of the logical operation relationship, and the RVA is used to indicate that the following information is placed on the left side of the logical operation relationship. Therefore, the physical meaning of each of the above-mentioned triples is as follows:

"EQUAL:{LVA:EPS-Lenkerposition, RVA:2}" is used to indicate that the signal value of the first sensor signal "EPS-Lenkerposition" is equal to 2;

"GTE:{LVA:FT-FH-Oeffnung, RVA: 0}" is used to indicate that the signal value of the second sensor signal "FT-FH-Oeffnung" is greater than or equal to 0;

"LTE:{LVA:FT-FH-Oeffnung, RVA:200}" is used to indicate that the signal value of the second sensor signal "FT-FH-Oeffnung" is less than or equal to 200;

"GTE:{LVA:FT-FH-Fang, RVA: 0}" is used to indicate that the signal value of the third sensor signal "FT-FH-Fang" is greater than or equal to 0;

"LTE:{LVA:FT-FH-Fang, RVA: 1}" is used to indicate that the signal value of the third sensor signal "FT-FH-Fang" is less than or equal to 1;

"EQUAL:{LVA:FT-FH-normiert, RVA: 1}" is used to indicate that the signal value of the fourth sensor signal "FT-FH-normiert" is equal to 1.

As shown in Figure 3, the value of the action key "ACTION" corresponding to the condition key "CONDITION" is "state: valid", which is used to indicate when the signal value of each sensor signal meets the conditions indicated by the above six triples, The value of the message parameter "state" is "valid".

In addition, as shown in FIG. 3, the value corresponding to the first condition key may not only include the six triples mentioned above, but also include the keyword "AND" used to indicate the logical relationship between the triples. When it indicates that these six triples need to be satisfied at the same time, the value of the message parameter "state" can take "valid".

That is, the first condition key may also include a logical operator used to indicate whether each triplet is a logical AND or a logical OR.

Optionally, the first condition key may not include a logical operator used to indicate whether each triplet is a logical AND or a logical OR. At this time, the logical relationship between each triplet may be a pre-default relationship, which is not specifically limited in the embodiment of the present application.

Since the rule configuration file stores the message generation rules in a key-value manner, it is necessary to define the semantics of each key in the rule configuration file through the rule grammar. Table 3 is a semantic description of each key in an extended rule grammar provided by an embodiment of the present application.

table 3

It should be noted that the above Table 3 is only used to illustrate the semantics of some keys in the extended grammar. When using the rule configuration file provided by the embodiment of this application, you can continue to expand other keys according to your needs. You only need to specify these in the rule grammar. The semantics of the over-occupied key is sufficient.

The above is a key-value way to explain how the first rule configuration file indicates the generation rule of the first message. Optionally, if the rule configuration file stores the generation rule of the first message in other ways, only the corresponding rule grammar needs to be expanded at this time, and the examples are not described here.

Based on the above explanation of the rule configuration file, it can be known that the rule configuration file for each message is pre-configured. In order to facilitate the quick acquisition of the rule configuration file of each message in the follow-up, the rule configuration file of each message and the identifier of the message may be stored in the message identifier processing mapping table in advance. Therefore, after the signal processing unit receives the signal data packet, it can obtain the rule configuration file corresponding to the first message identification from the message identification processing mapping table based on the identification of the first message in the signal data packet. This process can also be referred to as "MCU message distribution".

In addition, the multiple signal values corresponding to multiple sensor signals in step 201 may mean that multiple signal values correspond to multiple sensor signals one-to-one. The number of multiple signal values may also be less than the number of multiple sensor signals. In this case, one sensor signal may correspond to two or more signal values, which is not specifically limited here.

Step 202: The signal processing unit processes the multiple signal values based on the rule grammar and the first rule configuration file to obtain the parameter value of each message parameter in the first message.

It can be seen from step 201 that the first rule configuration file is a file after the generation rule of the first message is processed based on the extended rule grammar. Therefore, after the signal processing unit obtains the signal data packet, it can be directly based on the rule grammar and the first rule. The configuration file processes the multiple signal values to obtain the parameter value of each message in the first message. The parameter value of each message parameter in the first message can be obtained without writing the code for the generation rule of the first message first.

In a possible implementation manner, a rule execution engine may be pre-deployed in the signal processing unit, and the rule execution engine is loaded with the rule grammar. The rule grammar is used to interpret the rule configuration file. Therefore, in step 202, the signal processing unit may call the rule execution engine to process the multiple signal values based on the first rule configuration file to obtain the first message The parameter value of each message parameter.

If the rule configuration file stores the generated rules in a key-value manner, the rule grammar is loaded into the rule execution engine at this time, indicating that the rule execution engine has learned the semantics of each key defined in the rule grammar. In this scenario, the way that the rule execution engine processes these multiple signal values based on the first rule configuration file can be implemented as follows: for a certain condition key for any message parameter in the first rule configuration file, pairing based on the rule syntax Perform semantic analysis on the value of the condition key. For example, perform semantic analysis on the above-mentioned first triplet to obtain a condition "The signal value of the first sensor signal "EPS-Lenkerposition" is equal to 2". At this time, multiple signals are judged If the signal value of the first sensor signal satisfies the condition, if it satisfies the condition, it will continue to judge whether the other triples in the condition key are satisfied, and if they are all met, then obtain the value of the action key corresponding to the condition key. The value is the parameter value of the message parameter. If the condition indicated by any triplet in the condition key is not satisfied, then the next condition key of the message parameter will continue the above processing process until a satisfied condition key is obtained. This process can be shown by the processing flowchart shown in FIG. 4, which will not be described in detail here.

In addition, which sensor signal corresponds to each signal value in the signal data packet in step 210 can be directly formulated in advance through a configuration file, that is, the data structure in the signal data packet is indicated through the configuration file. Therefore, after receiving the signal data packet, the signal processing unit can also analyze the signal data packet based on the configuration file to obtain the multiple signal values, and determine which signal value corresponds to which sensor signal. The configuration file method can also avoid increasing the workload of manual coding.

After the signal processing unit obtains the parameter value of each message parameter in the first message through step 202, it can send the parameter value of each message parameter in the first message to the data collection server, so that the data collection server can use the information in the first message. The parameter value of each message parameter performs operations such as intelligent control of the vehicle.

When the signal processing unit reports the parameter value of each message parameter in the first message to the data collection server, it may also send the parameter value of each message parameter in the first message in the form of a message data packet. At this time, the specific structure of the message data packet can be specified in advance through a configuration file. For example, the configuration file can specify which fields in the message data packet correspond to the parameter value of the first message parameter and which fields correspond to the parameter value of the second message parameter. In this way, when the signal processing unit reports the parameter value of each message parameter in the first message to the data collection server, it only needs to generate a message data packet according to the format specified in the configuration file.

The above-mentioned complete process from step 201 to step 202 can be further illustrated by the flow shown in FIG. 5. As shown in FIG. 5, the signal processing method provided by the embodiment of the present application may include two aspects, one is the preparation phase and the other is the operation phase.

The preparation stage mainly includes the following three aspects:

Step 1: Generate a rule configuration file for each message based on the rule grammar.

Step 2: Generate a configuration file for the data structure of the signal data packet.

Step 3: Generate a configuration file for the data structure of the message data packet.

The operation phase includes the following five aspects:

Step 1: The MCU reports the signal data packet.

Step 2: The signal processing unit obtains the first rule configuration file of the first message from the message identification processing mapping table based on the identification of the first message. This step can be called "MCU message distribution".

Step 3: The signal processing unit sends each signal value and the first rule configuration file to the rule execution engine through the message processing entry.

Step 4: The rule execution engine first determines which sensor signals the multiple signal values correspond to, based on the configuration file for the data structure of the signal data packet. Then, the parameter value of each message parameter in the first message is determined based on the first rule configuration file and the signal value of each sensor signal, and finally the message data packet is generated based on the configuration file for the data structure of the message data packet.

Step 5: The signal processing unit reports the message data packet to the data collection server.

The process shown in Figure 5 has the following technical effects compared to the hard-coded method of writing the processing function of each message in the traditional technology:

(1) In the traditional technology, the processing function of each message is written by hard coding. At this time, it is equivalent to the selection of each sensor signal corresponding to each combination shown in Table 2 (the value of the message parameter in each row in Table 2) Value) is hard-coded, resulting in a high degree of similarity in each part of the code of the written processing function, which in turn leads to poor readability of the code. However, in the embodiment of the present application, the message generation rules can be indicated only through the rule configuration file, which avoids the need to write codes in a hard coding manner, thereby eliminating the technical problems caused by hard coding.

(2) Once the message processing function written by hard coding in the traditional technology is released, the generation rule of the message will not be changed. If the message generation rules are changed, the processing function needs to be rewritten and republished. However, in the embodiment of the present application, when the generation rule of a certain message changes, only the rule configuration file of the message needs to be adaptively modified, and the modified rule configuration file is subsequently loaded by the execution engine.

(3) At present, there is no unified vehicle regulation requirement for the on-board signal data collection of various depots, and the signal processing rules of each depot are also different. Therefore, the reusability of the code of the message generation rule for the signals collected by each depot is also compared. Difference. This leads to the need to maintain different message generation rule codes for different depots, which increases the maintenance cost of the message generation rule codes. However, in the embodiment of the present application, a unified rule grammar is provided, and the conversion of the rule configuration file to the generation rule only needs to be completed by the rule engine, which can meet the demand of the car factory for data collection differentiation. Therefore, different car manufacturers can load the relevant modules of the signal processing method provided in the embodiments of the application on the vehicle to realize signal processing. In this way, data collection functions of multiple manufacturers can be shared and reused, thereby reducing the difficulty and difficulty of product software implementation. Workload.

In addition, based on step 201 to step 202, it can be known that in this embodiment of the present application, the signal processing unit can directly determine the parameter value of each message parameter in the message through the rule configuration file. The rule configuration file is used to indicate the generation rules of the message. Therefore, if the message generation rule is changed, only the rule configuration file needs to be modified, and there is no need to rewrite the entire rule configuration file.

Therefore, in a possible implementation manner, the signal processing unit may also receive a configuration file update request, the configuration file update request carrying the identifier of the first message and the changed content in the generation rule of the first message; Identify the first rule configuration file to be acquired; update the rule configuration file according to the aforementioned changes.

If the first rule configuration file indicates the generation rule of the first message through the key-value method based on the rule grammar, in this scenario, the above-mentioned implementation method of updating the first rule configuration file according to the aforementioned change content may be: according to the change content , Determine the key to be modified in the first rule configuration file based on the rule grammar; modify the value corresponding to the determined key according to the content of the change. In order to facilitate subsequent generation of the first message based on the modified first rule configuration file.

That is, when the first rule configuration file indicates the generation rule of the first message through the key-value method based on the rule grammar, at this time, if the generation rule of the first message changes, then you only need to follow the rules in the generation rule. Modify the corresponding key value without modifying other content in the rule configuration file.

For example, for the rule configuration file shown in Figure 3, if the change content of the first message parameter in the generation rule is: in the condition that the parameter value of the first message parameter is valid, the condition that the second sensor signal needs to meet Modify it to be greater than or equal to 100. In this case, you need to take the action key valid according to the parameter value of the first message parameter to find the corresponding condition key, and then modify the value corresponding to the condition key as follows: Change the "second sensor signal "FT-FH-Oeffnung" The signal value of "is greater than or equal to 0" is modified to "the signal value of the second sensor signal "FT-FH-Oeffnung" is greater than or equal to 100". At this time, just replace the "0" in "GTE:{LVA:FT-FH-Oeffnung, RVA: 0}" in Figure 3 with "100".

For another example, for the rule configuration file shown in Figure 3, if the content of the first message parameter change in the generation rule is: in the condition that the parameter value of the first message parameter is valid, the second sensor signal needs to be satisfied The condition is modified to be less than or equal to 0. In this case, you need to take the action key valid according to the parameter value of the first message parameter to find the corresponding condition key, and then modify the value corresponding to the condition key as follows: Change the "second sensor signal "FT-FH-Oeffnung" The signal value of is greater than or equal to 0" is modified to "The signal value of the second sensor signal "FT-FH-Oeffnung" is less than or equal to 0". At this time, you only need to replace "GTE" in "GTE:{LVA:FT-FH-Oeffnung, RVA: 0}" in Figure 3 with "LTE".

For another example, for the rule configuration file shown in Figure 3, if the change content of the first message parameter in the generation rule is: in the condition that the parameter value of the first message parameter is valid, a signal of the target sensor signal needs to be added The value needs to meet the condition that the target sensor signal is not originally in the first rule configuration file. In this case, it is necessary to first take the action key valid according to the parameter value of the first message parameter to find the corresponding condition key, and then add the triple corresponding to the target sensor signal to the value corresponding to the condition key.

For another example, for the rule configuration file shown in Figure 3, if the change content of the first message parameter in the generation rule is: in the condition that the parameter value of the first message parameter is valid, the second sensor signal needs to be deleted. condition. In this case, you need to take the action key valid according to the parameter value of the first message parameter to find the corresponding condition key, and then modify the value corresponding to the condition key as follows: "The corresponding triples can be deleted. At this time, you only need to delete "GTE:{LVA:FT-FH-Oeffnung, RVA:0}" in Figure 3.

That is, in the embodiment of the present application, the content of the change in the generation rule of the first message may mean that the condition that a certain sensor signal needs to meet has changed, or it may mean that the parameter value of a certain message parameter needs to be satisfied. The condition of adding a sensor signal to the condition can also refer to the condition of deleting a sensor signal from the condition that the parameter value of a certain message parameter needs to meet. I will not give examples one by one here.

It should be noted that the above configuration file update request may be received in the process of determining the first message based on the first rule configuration file. That is, in the process of generating the first message, the first rule configuration file can also be updated, and only the rule execution engine needs to load the updated first rule configuration file in time, so as to realize the hottest of the rule configuration file. Revise.

So that in the subsequent process of generating messages, the rule configuration file can be parsed only based on the rule grammar, so as to determine the parameter value of each message parameter based on the generation rule indicated in the rule file. In this way, even if the message generation rule changes in the future, only the corresponding rule configuration file needs to be changed, and the entire rule configuration file does not need to be recompiled. In this way, it is possible to avoid writing the code of the generation rules by hard coding, which leads to the problem of rewriting all the codes when updating the generation rules.
