It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The first embodiment is as follows:
fig. 1 is a flowchart of a multi-level skipping method for electricity data according to an embodiment of the present disclosure, where the multi-level skipping method for electricity data provided in this embodiment may be performed by a multi-level skipping device for electricity data, the multi-level skipping device for electricity data may be implemented in a software and/or hardware manner, and the multi-level skipping device for electricity data may be formed by two or more physical entities or may be formed by one physical entity. Generally, the multi-stage jump transmission device of the power utilization data can be a circuit internet of things system.
The following description will be made by taking the multi-stage skip transmission device of the electricity consumption data as an example of a main body of a multi-stage skip transmission method for executing the electricity consumption data. Referring to fig. 1, the method for multi-level skip transmission of power consumption data specifically includes:
s110, the data management node determines a signal test result of each intelligent electric meter, each intelligent electric meter is graded based on the signal test result, corresponding first-level nodes, second-level nodes and third-level nodes are determined, corresponding data jump transmission links are constructed based on the first-level nodes, the second-level nodes and the third-level nodes, the data jump transmission links are sent to each corresponding intelligent electric meter, and each intelligent electric meter jumps power utilization data to the first-level nodes based on the data jump transmission links.
The multistage jump transmission method of the electricity consumption data in the embodiment of the application aims to classify each intelligent electric meter through signal testing, and a corresponding data jump transmission link is constructed according to the classification result of each intelligent electric meter, so that each intelligent electric meter in the data jump transmission link carries out electricity consumption data jump transmission based on the data jump transmission link, the electricity consumption data of each intelligent electric meter in the data jump transmission link are subjected to jump transmission to a first-stage node, and the electricity consumption data are collected and transmitted to a data management node through the first-stage node. Therefore, each intelligent electric meter can jump to transmit electricity utilization data nearby, and the stability of electricity utilization data transmission is further guaranteed. And the primary node is selected based on the signal test result, the data transmission quality between the primary node and the data management node is relatively better, the network stability of power utilization data transmission can be guaranteed, and the data transmission effect is optimized.
Specifically, when the electricity data are subjected to multi-level jumping transmission, signal testing of each intelligent electric meter is firstly carried out, the intelligent electric meters are further divided into first-level nodes, second-level nodes and third-level nodes, one or more intelligent electric meters with the best signal transmission quality are selected as the first-level nodes through classification of the intelligent electric meters, and the electricity data subjected to jumping transmission of each intelligent electric meter in the data jumping transmission link are collected and transmitted to the data management node. It is understood that the smart meters are distributed at various locations within the communication range of the data management node. When different intelligent electric meters perform data interaction with the data management node, the signal quality is different under the influence of signal multipath fading. In order to optimize the signal transmission effect and reduce the influence of signal attenuation, for part of smart meters with relatively poor signal communication quality with the data management node, other smart meters can be selected as communication relays, the communication relays are used for relaying the electricity utilization data to the primary node, the primary node summarizes the electricity utilization data of the data hopping transmission link and transmits the electricity utilization data to the data management node, and therefore better electricity utilization data transmission performance is guaranteed.
Further, referring to fig. 2, when performing a signal test, the data management node 11 receives a test signal sent by each smart meter 12, determines a corresponding signal quality parameter based on each test signal, and takes each signal quality parameter as a signal test result of each smart meter 12. And after receiving the test signal, the data management node further measures and calculates a signal quality parameter corresponding to the test signal, and determines the communication quality between each intelligent electric meter and the data management node based on the signal quality parameter. In particular, the signal quality parameter value of the test signal is determined by the corresponding signal received power, signal received strength, channel instantaneous quality value and/or interference signal strength. Wherein the channel instantaneous quality value represents the channel quality, channel matrix feedback, signal response, and/or interference information for the corresponding signal receiving antenna. And measuring the various types of parameters through the corresponding test signals and the antenna parameters. Further, in order to quantize the signal quality parameter, a calculation formula of the signal quality parameter is provided to quantize the signal quality of the test signal, and the calculation formula of the signal quality parameter is:
where f is the signal quality parameter value, P is the signal received power, d1For signal received strength, h is the instantaneous quality value of the channel, d2For interfering signal strength, omega1，ω2，ω3And ω4The influence factors are determined according to actual tests and can be set according to the actual influence of each type of parameter on the signal quality parameter value. Based on the signal quality parameter calculation formula, the signal quality parameters of the test signals can be determined. It should be noted that, in practical applications, according to different signal quality evaluation criteria, a plurality of different manners may be selected to evaluate the signal quality parameters of each test signal, and a corresponding quantization formula is set accordingly. The above formula is only one calculation method for calculating the signal quality parameter in the embodiment of the present application, and various different measurement and calculation formulas may be selected according to actual measurement and calculation requirements, which is not described herein again.
And grading each intelligent electric meter by the data management node based on the determined signal quality parameters corresponding to each intelligent electric meter. The first-level node is determined according to the set first signal quality parameter threshold, and it can be understood that if the signal quality parameter corresponding to the smart meter reaches the first signal quality parameter threshold, the first-level node is classified. Similarly, a primary node is determined according to a set first signal quality parameter threshold and a set second signal quality parameter threshold, and if the signal quality parameter corresponding to the intelligent electric meter is lower than the first signal quality parameter threshold and higher than the second signal quality parameter threshold, the intelligent electric meter is classified into the secondary node. And classifying the smart meter with the corresponding signal quality parameter lower than the second signal quality parameter threshold value into three-level nodes. The primary node serves as a terminal of the data jump transmission link and is used for summarizing power consumption data uploaded by each secondary node in the link and uploading the power consumption data to the data management node. The secondary node is used as a relay of the tertiary node and used for receiving the electricity utilization data of the tertiary node and jumping and transmitting the electricity utilization data of the secondary node and the tertiary node to the primary node, so that the electricity utilization data jumping and transmission based on the data link are realized.
Specifically, when a data hopping transmission link is constructed, according to the diversity of each smart meter, one secondary node closest to the smart meter is selected as a superior node in the communication range of the tertiary node, one primary node closest to the smart meter is selected as a superior node in the communication range of the secondary node, the data management node is used as a superior node of the primary node, and each corresponding data hopping transmission link is constructed based on the primary node, the secondary node, and the superior node of the tertiary node. It can be understood that after the upper node of each smart electric meter is determined, the upper node can be used as a receiving object of the electricity consumption data, and the electricity consumption data can be summarized to the first node step by step. After the data hopping transmission link is constructed, the data management node sends the data hopping transmission link to each intelligent electric meter in the corresponding data hopping transmission link so as to inform the current data hopping transmission link that each intelligent electric meter hops and summarizes the electricity consumption data to the primary node according to the superior node indicated by the data hopping transmission link. It can be understood that, based on the data jump transmission link, when each intelligent electric meter performs power consumption data jump transmission, a superior node of the power consumption data of each intelligent electric meter can be determined from the data jump transmission link, and then the power consumption data is jump-transmitted to the superior node, so that the power consumption data of each intelligent electric meter is jump-transmitted and summarized step by step in the data jump transmission link, and the collection of the power consumption data by the primary node can be completed. Through the higher level node of smart electric meter selection power consumption data nearby, transmit power consumption data in shorter communication distance in order to reduce the influence that the signal faded, guarantee data transmission's stability, and then promote power consumption data transmission quality.
In one embodiment, the data management node performs signal testing on each intelligent electric meter again every other set time period, ranks each intelligent electric meter again based on a new signal testing result, and constructs a new data jump transmission link based on a ranking result. Considering that the data transmission network is influenced by various factors, the data transmission quality of the data transmission network also changes in real time. In order to guarantee the jump transmission quality of the power consumption data, it is necessary to ensure that good data transmission performance is maintained between the data management node and the primary node in real time. Based on this, the embodiment of the application performs periodic signal testing on each smart meter by setting a time period, and obtains the signal testing results of each smart meter and the data management node by referring to the signal testing mode of the data management node. And the intelligent electric meter can be reclassified based on the new signal test result. If the signal transmission quality of the original first-level node and the data management node is found to be optimal according to the signal test result, the data link does not need to be reconstructed, otherwise, the grading of the intelligent electric meter needs to be performed again, and then the data jump transmission link is reconstructed based on the step S110, so that the stability of power transmission is guaranteed in real time.
S120, the identity of the primary node is sent to a third-party server, the third-party server generates a corresponding encryption key and a corresponding decryption key based on the identity of the primary node, the encryption key is sent to the primary node, and the decryption key is returned to the data management node corresponding to the identity of the primary node.
After the data jump transmission link is constructed, the data management node also sends the identity of the primary node to a third-party server so as to generate a power utilization data session key in the following process. And after the third-party server receives the identity of the first-level node, generating a unique session key by the identity of the third-party server corresponding to the first-level node. The session key comprises an encryption key and a decryption key, wherein the encryption key is sent to the first-level node and used for data encryption transmission, and the decryption key is sent to the data management node and used for subsequent power consumption data decryption. The session key may be a set of session keys shared by the primary nodes, and the data management node receives a decryption key accordingly. The session key may also be set for each level-one node, and the data management node receives a plurality of decryption keys. It can be understood that, in the embodiment of the present application, the encryption key is respectively sent to the first-level node, and the decryption key is sent to the data management node, so that the session key can be separately used, the difficulty of key decryption is increased, and the security of data transmission is further ensured. In addition, the third-party server is a trusted key management server and is used for generating a corresponding session key for subsequent encrypted transmission of the power utilization data by each primary node. It can be understood that the security of data transmission can be guaranteed by carrying out the encrypted transmission of the electricity data through the session key. In addition, the session key is managed by the trusted third-party server, so that the session key management process of the data management node can be saved, the service processing burden of the data management node is reduced, and the service processing efficiency is optimized.
In an embodiment, the third-party server generates a new encryption key and a new decryption key corresponding to the identity of the first-level node every other key management period, updates the new encryption key to the first-level node, and updates the new decryption key to the data management node corresponding to the identity of the first-level node. It can be understood that the encryption key and the decryption key are periodically updated, so that the difficulty of key decryption can be increased, and the situation that the electricity consumption data is stolen and tampered due to the fact that the session key is easily decrypted is avoided. Therefore, the safety of power utilization data transmission is improved, and the operation of the power internet of things is optimized.
S130, the primary node collects the electricity utilization data jumped by the intelligent electric meters in the corresponding data jump transmission link, the encryption key is used for encrypting and packaging the electricity utilization data into an electricity utilization data packet, and the electricity utilization data packet is sent to the data management node.
S140, the data management node receives the electricity utilization data packet, and decrypts the electricity utilization data packet based on the decryption key to obtain each electricity utilization data.
Further, referring to fig. 3, when the electricity consumption data is uploaded, each smart electric meter 12 grouped by the current electric meter sends the electricity consumption data to the third-level node according to the data skip transmission link issued by the data management node, wherein the third-level node sends the electricity consumption data to the second-level node, the second-level node summarizes the electricity consumption data of the third-level node, the electricity consumption data of the third-level node is sent to the first-level node according to the electricity consumption data set, and the electricity consumption data are skipped step by step through the electricity consumption data, so that the electricity consumption data are summarized to the first-level node. After the primary node acquires the power consumption data of each intelligent electric meter 12 of the current data jump transmission link, validity verification of the power consumption data is firstly carried out to avoid that the power consumption data are transmitted by an illegal node in a false mode. The electricity utilization data comprise an identity label corresponding to the intelligent electric meter; and the primary node extracts the identity marks contained in each electricity utilization data and compares the corresponding data jump transmission links one by one, and if the identity marks of the electricity utilization data are consistent with the intelligent electric meters of the corresponding data jump transmission links, the electricity utilization data are verified to be effective. It can be understood that, when each smart meter uploads the electricity data, the identity of each smart meter is attached to the electricity data. Correspondingly, each intelligent electric meter of the current link is included in the data jump transmission link, and if the identity mark included in certain electricity consumption data is inconsistent with the intelligent electric meter in the data jump transmission link, the electricity consumption data is invalid and does not belong to the intelligent electric meter of the current data jump transmission link.
As shown in fig. 3, after the validity verification of the electricity consumption data is completed, the primary node packages and encrypts each electricity consumption data into an electricity consumption data packet based on an encryption key issued by the third-party server 13 in advance, and further sends the electricity consumption data to the data management node 11. Referring to fig. 3, after receiving the electricity consumption data packet, the data management node 11 may decrypt the electricity consumption data packet based on a decryption key corresponding to the first-level node identifier issued by the third-party server 13 in advance, so as to obtain electricity consumption data of each smart meter grouped by corresponding meters.
In an embodiment, the data management node further compares the identity of each power consumption data based on the corresponding data hopping link, and performs integrity judgment on each power consumption data. It is understood that the electricity consumption data includes an identification of the corresponding smart meter. When the data management node verifies the integrity of the electricity consumption data based on the corresponding data jump transmission links, the corresponding data jump transmission links are compared one by one through extracting the identity of the electricity consumption data, and if the identity of one intelligent electric meter is lacked, the electricity consumption data of the intelligent electric meter is represented to be lacked. Similarly, based on the data jump transmission link, whether the data is tampered or not can be compared. Optionally, after determining that the power consumption data of a certain smart electric meter is missing, the data management node may send a data extraction instruction to the first-level node to instruct the first-level node to upload the power consumption data of the corresponding smart electric meter again, so as to ensure the integrity of the power consumption data acquisition.
Further, based on the acquired electricity utilization data, the data management node can perform electricity utilization data statistics and storage on each intelligent electric meter based on the identity of each intelligent electric meter. In addition, according to the electricity utilization data of each intelligent electric meter, the related service can be processed.
In one embodiment, when the data management node detects the primary node failure, one smart meter is reselected from the meter grouping as a new primary node based on the signal test result. It can be understood that, when the primary node fails and the power consumption data cannot be summarized and transmitted, in order to ensure normal acquisition of the power consumption data, referring to the above steps S110 to S120, the data management node reselects an intelligent electric meter with the optimal data transmission quality (except for the original superior node) as a new primary node according to the previous signal test result. And constructing a data jump transmission link based on the new primary node to ensure that the electricity utilization data corresponding to the intelligent electric meter can be summarized to the new primary node. Correspondingly, the third-party server generates a corresponding encryption key and a corresponding decryption key based on the identity of the new primary node, sends the encryption key to the new primary node, and returns the decryption key to the data management node corresponding to the identity of the new primary node. Therefore, the new primary node can perform summary transmission of the electricity consumption data of each intelligent electric meter of the corresponding data jump transmission link. By replacing the primary node when the primary node fails, the stability of power consumption data transmission can be guaranteed, and the power consumption data transmission is prevented from being influenced. In addition, when the primary node fails, each intelligent electric meter of the data hopping transmission link corresponding to the primary node can also select other primary nodes as a summary transmission object of the electricity consumption data of the intelligent electric meter, and the electricity consumption data can be hopped to the reselected primary node by selecting the hopping transmission object nearby, so that the hopping transmission summary of the electricity consumption data is realized.
The method comprises the steps that a signal test result of each intelligent electric meter is determined through a data management node, each intelligent electric meter is graded based on the signal test result, corresponding first-level nodes, second-level nodes and third-level nodes are determined, corresponding data hopping transmission links are constructed based on the first-level nodes, the second-level nodes and the third-level nodes, the data hopping transmission links are sent to the corresponding intelligent electric meters, and each intelligent electric meter hops electricity utilization data to the first-level nodes based on the data hopping transmission links; the identity identification of the first-level node is sent to a third-party server, the third-party server generates a corresponding encryption key and a corresponding decryption key based on the identity identification of the first-level node, the encryption key is sent to the first-level node, and the decryption key is returned to the data management node corresponding to the identity identification of the first-level node; the primary node collects all electricity consumption data jumped by all intelligent electric meters in corresponding data jump transmission links, encrypts and packages all the electricity consumption data into electricity consumption data packets by using encryption keys, and sends the electricity consumption data packets to the data management node; and the data management node receives the electricity utilization data packet and decrypts the electricity utilization data packet based on the decryption key to obtain each electricity utilization data. By adopting the technical means, the power utilization data transmission effect can be optimized, the power utilization data transmission quality is improved, and the safety of power utilization data transmission is guaranteed.
