Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

In order to better understand the technical solutions of the embodiments of the present application, first, a system architecture that may be related to the embodiments of the present application is described. Referring to fig. 1, a schematic system architecture is provided in an embodiment of the present application, where the system architecture may include: an in-vehicle terminal 100 and a server 200. Wherein communication between the in-vehicle terminal 100 and the server 200 can be performed through a network. The network communication may be based on any wired and wireless network including, but not limited to, the internet, wide area networks, metropolitan area networks, local area networks, virtual private networks (virtual private network, VPN), and wireless communication networks, among others.

The in-vehicle terminal 100, also called in-vehicle apparatus, in-vehicle computer, or in-vehicle machine. In this embodiment of the present application, the method may be used for collecting a vehicle signal, generating a signal packet from the vehicle signal, and communicating with the server 200, and specifically may be used for reporting the signal packet to the server 200.

The memory may be used to store software programs and data, and the processor may execute various functional applications and data processing of the in-vehicle terminal 100 by executing the software programs and data stored in the memory. In embodiments of the present application, the processor may be configured to collect vehicle signals. The communication interface may be used to communicate with the server 200, for example, to report signal messages to the server 200.

A vehicle box (T-box, or TCU) is a very important component in the vehicle-mounted terminal 100, mainly for communication between the outside of the car and a server and other terminals (e.g., a cellular phone). The T-box may acquire data of each electronic control unit (electronic control unit, ECU) through a controller area network (controller area network, CAN) bus, for example, a vehicle condition report, a driving report, a fuel consumption statistics, a violation query, a location track, a driving behavior, etc., and transmit the data to a server through the network, so as to realize real-time monitoring of the vehicle, or facilitate subsequent testing of performance of the vehicle and analysis of driving behavior of a user.

It should be noted that, the vehicle-mounted terminal 100 may further include devices not related to the foregoing, for example, a whole vehicle computing unit, a bluetooth module, an audio module, a video module, a battery system, a map module, and other possible functional modules, which are not described herein.

The server 200 may be one server or may be a server cluster formed by a plurality of servers. In this embodiment of the present application, the server 200 may be in communication with the vehicle-mounted terminal 100, and may specifically be configured to receive an increment signal packet sent by the vehicle-mounted terminal 100, and may also be configured to parse the increment signal packet to obtain an increment signal. The server 200 may be a cloud server, a cloud platform of internet of vehicles, a cloud server of internet of vehicles, an internet of things device, a data center network device, a cloud computing device, a computer supporting 802.11 protocol, a network device in a public land mobile network (public land mobile network, PLMN) of future evolution, etc., which is not particularly limited in the embodiments of the present application.

It is understood that the system architecture shown in fig. 1 is only one exemplary implementation of the embodiments of the present application, and the system architecture in the embodiments of the present application includes, but is not limited to, the above system architecture.

At present, the new energy automobile mainly adopts national standard 32960 protocol or portion standard 808 protocol to finish reporting of data, and the protocols generally adopt full reporting, that is to say, all data acquired by the automobile need to be reported, and network resource waste is easily caused under the condition of excessive signal quantity.

In this regard, the embodiments of the present application provide a method, an apparatus, a computer device, and a storage medium for data transmission, which aim to improve data transmission efficiency and save network bandwidth resources.

In combination with the above system architecture, a method for data transmission according to an embodiment of the present application is described below. Referring to fig. 2, fig. 2 is a flowchart of a method for data transmission according to an embodiment of the present application. As shown in fig. 2, the method is illustrated by taking an in-vehicle terminal as an example, and the method may include steps S201 to S204.

Step S201: the vehicle-mounted terminal collects vehicle signals of a target vehicle.

In the embodiment of the application, the target vehicle is a vehicle for which a vehicle signal is to be acquired. The vehicle signals may include control data and travel data generated during operation of the target vehicle, such as range, average fuel consumption, vehicle speed, residual charge, and the like. The vehicle signal may also include, without limitation, position information, remaining oil, air conditioning temperature, status of side lights, etc., or other operational data responsive to the status of the target vehicle. It is understood that each vehicle signal includes at least a signal name and a corresponding state value, for example, the vehicle signal is a remaining power, and the corresponding state value may be 80%.

In an embodiment of the present application, one of the vehicle signals corresponds to a signal identifier that is used to determine the type of vehicle signal. For example, the signal identifier of the driving range may be "0x7E01", the signal identifier of the driving range may be "0x7E02", and conversely, "0x7E01" may represent the driving range, and "0x7E02" may represent the driving range. That is, each vehicle signal has a unique signal identifier from which the type of vehicle signal can be determined.

In some possible embodiments, the collecting the vehicle signal of the target vehicle specifically includes the steps of: acquiring identification information of the target vehicle; determining the type of a vehicle signal to be acquired according to the identification information, wherein the type of the vehicle signal comprises a driving mileage, a cruising mileage, average oil consumption or a vehicle speed; and collecting the vehicle signal according to the type of the vehicle signal to be collected.

In the embodiment of the application, the identification information may be a vehicle identification code (vehicle identification number, VIN), a license plate number, or other identifications representing the identity of the vehicle. It will be appreciated that each target vehicle has a unique VIN, as well as a unique license plate number. According to the identification information of the target vehicle, the type of the vehicle of the target vehicle is identified, the type of the vehicle signal to be acquired is determined, and then the vehicle signal required by the target vehicle can be known.

For example, the data structure defines the types of 80 vehicle signals, the vehicle-mounted terminal acquires the VIN of the target vehicle through an in-vehicle network (such as a CAN network), and determines that 60 types of vehicle signals to be acquired of the target vehicle exist according to the VIN, so that the vehicle-mounted terminal only acquires 60 vehicle signals of the target vehicle in a targeted manner, and the vehicle signals of the remaining 20 vehicle signals which do not exist of the target vehicle are not acquired. It can be seen that the vehicle signal acquisition strategy obtained by the embodiment of the application is configured according to the requirement, the vehicle signals in the acquisition strategy correspond to the identification information, and no redundant vehicle signals or no vehicle signals of the target vehicle can be generated, so that the acquisition of the vehicle signals is more targeted, and the acquisition efficiency of the vehicle signals is improved.

Step S202: and the vehicle-mounted terminal compares the vehicle signal with the vehicle signal reported last time to obtain an increment signal.

In the embodiment of the application, the increment signal is a vehicle signal with data change, wherein the vehicle signal acquired at this time is compared with the vehicle signal reported last time. For example, the driving distance in the vehicle signal collected this time is 35km, the remaining power is 98%, the driving distance in the vehicle signal reported last time is 30km, and the remaining power is 98%. It will be appreciated that, in the acquired vehicle signal, the data of the driving range changes, while the data of the remaining power does not change, compared with the vehicle signal reported last time, the incremental signal is only the driving range. For example, if 80 vehicle signals are successfully acquired, 60 vehicle signals are changed compared with the last reported vehicle signal, and then the increment signals are 60.

In some possible embodiments, before performing step S202, the following steps may be further included: and in response to the failure of the vehicle signal acquisition, uploading a signal abnormal message to a server, wherein the signal abnormal message is used for indicating the abnormal vehicle signal acquisition.

In this embodiment of the present application, the failure in acquiring the vehicle signal may refer to that one or more signals to be acquired do not acquire data, or may refer to that one or more signals to be acquired acquire abnormal data. If the data of the remaining power is usually 0-100% and the collected remaining power is 120%, the data of the remaining power is abnormal at this time. For example, if there are 80 vehicle signals to be collected by the target vehicle, but only 60 vehicle signals are successfully collected this time, and the remaining 20 vehicle signals are failed to be collected, the abnormal signal message of the vehicle signal which is failed to be collected may be set to "0000", and the vehicle-mounted terminal uploads the abnormal signal message to the server.

Optionally, if the vehicle-mounted terminal detects that the collected signal data is abnormal, the abnormal data can be directly deleted, so that the storage space is saved.

In some possible embodiments, if the vehicle signal is compared with the vehicle signal reported last time, the number of times that no incremental signal exists reaches a preset threshold, and the reporting frequency is adjusted so that the adjusted reporting frequency is smaller than the preset reporting frequency.

For example, the preset reporting frequency of the remaining power is once every 3 seconds, and the number of times that the increment signal is not present reaches the preset threshold (assumed to be 5 times). That is, the data of the remaining power is not changed for 5 consecutive times. At this time, the reporting frequency is adjusted, so that the adjusted reporting frequency is smaller than the preset reporting frequency. For example, the reporting frequency of the residual electric quantity is adjusted from a preset frequency of every 3 seconds to a frequency of every 5 seconds.

It should be noted that the reporting frequency of each vehicle signal may be identical or not, which is not limited in this application, and specific values are set by a technician according to actual situations.

Step S203: and the vehicle-mounted terminal generates an increment signal message according to the increment signal and a signal identifier corresponding to the increment signal.

In some possible embodiments, generating the increment signal packet according to the increment signal and the signal identifier corresponding to the increment signal may include the following steps: determining the type of the increment signal according to the signal identifier corresponding to the increment signal; determining the reporting sequence and byte length of the increment signal according to the type of the increment signal; according to the byte length, carrying out format conversion on the increment signal to obtain a reporting message body; and combining the reported message bodies according to the reporting sequence to obtain an increment signal message.

In the embodiment of the application, the user-defined protocol is adopted to report the vehicle signal, and the data structure of the reported message body can refer to the following table. Wherein one signal identifier corresponds to one vehicle signal. For example, if the data structure defines the type of 80 vehicle signals, the signal identifiers may be "0x7E01, 0x7E02, 0x7E03 … … 0x7E4F, 0x7E50". The byte length is determined according to the data length of the vehicle signal, and the larger the data length of the vehicle signal is, the larger the byte length is, for example, the byte length of the driving mileage is 4 bytes; conversely, if the data length of the vehicle signal is small, the byte length of the remaining oil amount is represented by 1 byte.

It should be noted that, the signal identifiers in the data structures shown in the following table are only examples, and the embodiment of the present application only defines that one vehicle signal corresponds to one signal identifier, and the format of the signal identifier is not limited, but may be other permutation and combination of numbers, letters or symbols, which is not limited. The vehicle signal types in the embodiments of the present application may include, but are not limited to, those listed in the following table, and in some possible implementations, may further include a vehicle speed, a remaining power, location information, an air-conditioning temperature, a side light status, etc., or other operation data capable of reflecting a target vehicle status, etc., which is not limited herein, and the corresponding data structure may refer to the following table.

Signal identifier	Byte length	Vehicle signal	Data type
				0x7E01	4	Mileage of travel	byte
0x7E02	2	Endurance of journeyProgram(s)	byte
				0x7E03	1	Residual oil quantity	byte
…	…	…	…

For example, the acquired incremental signal is a driving range, and the corresponding state value is 1222km. The signal identifier corresponding to the driving mileage is '0 x7E 01', the byte length is 4 bytes, and if hexadecimal message is selected, the increment signal message can be '7E 01000004c 6'. In the embodiment of the present application, the message is taken as an example in hexadecimal, and octal and binary may also be used, which is not limited herein. Wherein "0x" in the signal identifier indicates that the signal identifier is numbered in hexadecimal, and can be omitted in the message.

For example, the obtained incremental signal is a driving distance and a remaining oil quantity, the state value corresponding to the driving distance is 1222km, the state value corresponding to the remaining oil quantity is 69L, the incremental signal is subjected to format conversion according to the byte length of the type of the incremental signal to obtain a report message body, the report message body of the driving distance can be 7E01000004c6, the report message body of the remaining oil quantity can be 7E0345, and then the report message bodies are combined according to the report sequence (for example, the report sequence can be the sequence according to the signal identifier) to obtain an incremental signal message 7E01000004c67E 0345.

In some possible embodiments, any combination of reported message bodies may be reported, and the incremental signal message of the driving mileage and the remaining oil amount may also be "7E03457E01000004c6". It can be seen that the incremental signal message generating strategy is simpler and more flexible than the national standard 32960 protocol or the standard 808 protocol.

In some possible embodiments, the incremental signal message may further include identification information of the target vehicle, where the identification information may include, but is not limited to, VIN, license plate number, etc. information that may identify the identity of the target vehicle. In the embodiment of the application, the identification information of the target vehicle can be used as the head of the increment signal message, and the identity of the target vehicle can be quickly identified when the server analyzes the message, so that the data can be conveniently classified and arranged or subsequently called to test the performance of the automobile and analyze the driving behavior of the user.

Step S204: and the vehicle-mounted terminal reports the increment signal message to a server.

The vehicle-mounted terminal reports the increment signal message to the server through the T-box, so that the server can read and analyze the reported increment signal data. Optionally, when the vehicle-mounted terminal collects the vehicle signal data, the collected vehicle signal data can be stored in the vehicle-mounted terminal, so that the vehicle-mounted terminal can conveniently use the stored vehicle signal data as other processing.

It can be seen that the vehicle-mounted terminal reports the vehicle signal data to the server in an incremental reporting mode, that is, reports the vehicle signal with the collected data changed, and the data without the change is not reported. The data transmission quantity can be reduced, the data transmission efficiency is improved, and the network bandwidth resources are saved.

In connection with the above system architecture, another method for data transmission according to the embodiments of the present application is described below. Referring to fig. 3, fig. 3 is a flowchart of another data transmission method according to an embodiment of the present application. As shown in fig. 3, the method is illustrated by taking an example that the execution subject of the method is a server, and the method may include step S301, step 302, and step S303.

Step S301: the server receives the increment signal message.

Step S302: and the server analyzes the increment signal message to obtain a signal identifier corresponding to the increment signal.

Step S303: and the server obtains the increment signal according to the signal identifier corresponding to the increment signal.

Specifically, after receiving the increment signal message sent by the vehicle-mounted terminal, the server analyzes the increment signal message. In the embodiment of the application, the signal identifier of the increment signal can be obtained from the increment signal message, and the signal identifier is used as a query index, so that the type of the increment signal is determined. And then determining the byte length according to the type of the increment signal, and further completing the analysis of the increment signal message to obtain the increment signal and corresponding data. The server may store, forward, or otherwise process the obtained incremental signal and corresponding data, which is not limited.

Reference descriptions of the signal identifiers may refer to the foregoing definitions, and are not repeated herein. It can be seen that in the embodiment of the application, the server only needs to process the increment signal, so that the efficiency of data processing is greatly improved, and meanwhile, the network bandwidth resource is saved.

In some possible embodiments, if the server identifies the message as a signal abnormal message, the message may be discarded, thereby saving network resources.

Optionally, the server may further obtain identification information including the target vehicle from the incremental signal packet, and may quickly identify the identity of the target vehicle according to the identification information, so as to conveniently classify, sort, or subsequently invoke the incremental data to test the performance of the automobile and analyze the driving behavior of the user.
