Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises" and "comprising," and any variations thereof, as used in the present examples, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1, an implementation process of the method for identifying vehicle information provided in an embodiment of the present invention may include interaction between a mobile terminal, a first server, and a second server, where the method includes the following steps:
101. the mobile terminal acquires vehicle information.
The vehicle information comprises license plate information, appearance information and parameter information. In this embodiment, the type and the number of the acquired vehicle information may be selected according to the needs of the user, for example, the user may select the license plate information and the appearance information at the same time. Meanwhile, the license plate information and the appearance information can be pictures and videos, and the parameter information can be any one of texts, images and videos.
102. And the mobile terminal acquires the network information and determines a corresponding target sending mode according to the network information and the sending condition.
The sending condition includes a network state and a corresponding sending mode.
Since the mobile terminal is used to acquire and transmit the vehicle information, in order to avoid the problem that subsequent analysis fails due to abnormal data transmission (for example, packet loss and the like) in the case of a poor network, the current transmission mode can be determined based on the network information in this embodiment.
103. And the mobile terminal sends the vehicle information to a first server according to the target sending mode.
For example, when the network information determines that the network state is poor, the suspended transmission or the delayed transmission may be selected, so as to ensure the accuracy of the subsequent analysis result.
104. The first server receives the vehicle information.
In this embodiment, the first server may be understood as a relay server that performs data forwarding between the mobile terminal and the second server, so that the first server may be used to implement the function of sending the vehicle information.
105. The first server executes processing operation on the vehicle information to obtain a first data packet.
Wherein the processing operation comprises encryption processing and identity marking processing. In a specific application, any one or both of the two manners may be selected according to actual needs, which are not limited herein and may be selected according to actual needs.
106. And the first server sends the first data packet to a second server so that the second server can analyze the first data packet.
Since the first server is mainly used for forwarding the received vehicle information, and the subsequent analysis operation needs to be performed by the second server, the first data packet may be sent to the second server after the processing operation is performed by using the first server in the foregoing step.
107. The second server receives the first data packet.
In this embodiment, the manner of transmitting and receiving data may be based on an existing communication manner, and is not limited herein.
108. And the second server executes analysis operation on the first data packet to obtain the vehicle information.
The analysis operation comprises a decryption operation and an identity recognition operation.
Since the first server performs the processing operation on the vehicle information in the foregoing step, in this step, the second server needs to perform a corresponding parsing operation on the acquired first data packet. The decryption operation, i.e. the identification operation, executed in the specific parsing operation corresponds to the processing operation executed by the first server. For example, when the first server performs only the encryption processing, the second server may perform only the decryption operation in this step.
109. And the second server executes analysis operation according to the vehicle information and obtains the analysis result.
After the vehicle information has been obtained based on the parsing operation in step 108, the vehicle information may be analyzed to obtain a corresponding analysis result. Because the vehicle information may specifically include license plate information, appearance information, and parameter information, corresponding analysis results obtained based on different information types are also different and respectively correspond to different specific vehicle information. Therefore, the analysis result comprises a license plate analysis result, an appearance analysis result and a parameter analysis result.
110. And the second server generates the second data packet according to the analysis result and sends the second data packet to the first server so that the first server can obtain the analysis result based on the second data packet and feed the analysis result back to the mobile terminal.
After the second server obtains the analysis result, a second data packet can be generated according to the analysis result and sent to the first server, so that the first server can obtain the analysis result on the basis of the second data packet and feed the analysis result back to the mobile terminal, and the vehicle information analysis function is achieved.
In one possible embodiment, since the network status of the mobile terminal may change based on different factors, in order to ensure that the vehicle information is successfully transmitted, the transmission conditions may be divided into different network statuses and corresponding different transmission modes.
Therefore, the sending condition may include a first network state, a second network state and a third network state, the first network state is used for representing that the network state is good, the second network state is used for representing that the network state is general, and the third network state is used for representing that the network state is poor;
the first network state corresponds to a first sending mode, the second network state corresponds to a second sending mode, and the third network state corresponds to a third sending mode, wherein the first sending mode is used for representing direct sending, the second sending mode is used for representing batch sending according to data quantity based on the vehicle information, and the third sending mode is used for representing delayed sending;
based on this, the mobile terminal determines the matching target transmission method according to the network information and the transmission condition in step 102, and the execution may specifically include:
on one hand, when the network information is determined to accord with the first network state, the first sending mode is determined to be the target sending mode; therefore, when the network state is good, the vehicle information can be directly sent, so that the function of timely sending the vehicle information can be realized, and the timeliness of the method of the embodiment is integrally improved.
On the other hand, when the network information is determined to accord with the second network state, determining that the second sending mode is the target sending mode; therefore, when the network state is general, the vehicle information can be sent in batches, the situation of data loss during overall sending is avoided, and the problem that subsequent analysis fails due to data transmission failure possibly caused by further network deterioration can be avoided.
In yet another aspect, when it is determined that the network information conforms to the third network state, it is determined that the third sending method is the target sending method; in this way, it is ensured that the transmission of the vehicle information can be delayed when the network state is poor, thereby ensuring that the problem of analysis failure caused by data transmission failure is avoided.
In a possible implementation manner, as can be known from the description in the foregoing example, since the sending manners in different network states may be different, the sending step 103 sends the vehicle information to the first server according to the target sending manner, and the specific execution may include:
when the target sending mode is determined to be the first sending mode, directly sending the vehicle information to the first server;
when the target sending mode is determined to be the second sending mode, splitting the vehicle information into a plurality of pieces of sub-packet information according to a preset splitting rule, and sending the plurality of pieces of sub-packet information to the first server in batches, wherein the preset splitting rule comprises the maximum data volume of each sub-packet;
and when the target sending mode is determined to be the third sending mode, performing a delayed sending operation on the vehicle information, wherein the delayed sending operation is used for sending the vehicle information when the network state is restored to the target state, and the target state comprises a first network state and a second network state.
In this way, the vehicle information can be sent based on different modes, wherein when the vehicle information is split into a plurality of pieces of sub-packet information according to a preset splitting rule and the plurality of pieces of sub-packet information are sent to the first server in batches, the risk of data loss caused by sending the vehicle information in the whole sending process can be ensured, and the vehicle information is sent in a delayed time, so that the function of sending the vehicle information in time when the network state is recovered to be good or common can be ensured.
In a possible implementation, after the step 103 is followed by sending the vehicle information to the first server according to the target sending mode, the method further includes:
and sending an analysis result request to the first server according to a preset rule, wherein the preset rule comprises a request sending frequency and a request sending frequency threshold, and the analysis result request is used for requesting the first server for an analysis result of the vehicle information.
