Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method, apparatus, computer device, and storage medium for data transmission. Background Art

[0002] In order to improve the operational safety of new energy vehicles, energy vehicle manufacturers need to report vehicle driving-related data to achieve real-time supervision of new energy vehicles. In addition, vehicle manufacturers will also save the collected data in their own databases for subsequent use in testing vehicle performance and analyzing user driving behaviors.

[0003] Currently, new energy vehicles mainly use the national standard 32960 protocol or the ministry standard 808 protocol, etc. to complete data reporting. These protocols usually use full-volume reporting. That is, all data collected by the vehicle needs to be reported, which is likely to cause waste of network resources in the case of excessive signal volume. Summary of the Invention

[0004] An object of this application is to provide a method, apparatus, computer device, and storage medium for data transmission. Its advantage lies in that by adopting the incremental reporting method, vehicle signals with changed collected data are reported, and unchanged data is not reported, thereby reducing the data transmission volume, improving the data transmission efficiency, and saving network bandwidth resources.

[0005] Another object of this application is to provide a method, apparatus, computer device, and storage medium for data transmission. Its advantage lies in that by obtaining the identification information of the target vehicle and determining the type of vehicle signals to be collected, the collection of vehicle signals is made more targeted, thereby improving the collection efficiency of vehicle signals.

[0006] Another object of this application is to provide a method, apparatus, computer device, and storage medium for data transmission. Its advantage lies in that by reporting a signal exception message to the server to prompt the server that some vehicle signal collections are abnormal, it is convenient for the subsequent server to process the signal exception messages with collection failures.

[0007] Another object of this application is to provide a method, apparatus, computer device, and storage medium for data transmission. Its advantage lies in that generating an incremental signal message according to the incremental signal and the signal identifier corresponding to the incremental signal can make the message generation strategy for vehicle signals simpler and more flexible.

[0008] Another object of the present application is to provide a data transmission method, apparatus, computer device, and storage medium. Its advantage lies in that if the number of times there is no incremental signal reaches a preset threshold, the reporting frequency can be adjusted so that the adjusted reporting frequency is less than the preset reporting frequency, which can avoid the problem of waste of network bandwidth resources caused by the reporting frequency being too fast and the vehicle signals not having time to change.

[0009] To achieve the above object, in a first aspect, an embodiment of the present application provides a data transmission method, including the following steps:

[0010] Collect vehicle signals of a target vehicle. One signal in the vehicle signals corresponds to one signal identifier, and the signal identifier is used to determine the type of the vehicle signal;

[0011] Compare the vehicle signals with the previously reported vehicle signals to obtain incremental signals;

[0012] Generate an incremental signal message according to the incremental signal and the signal identifier corresponding to the incremental signal;

[0013] Report the incremental signal message to the server.

[0014] It can be seen that by adopting the incremental reporting method, the vehicle signals with changed collected data are reported, and the unchanged data is not reported, which can reduce the data transmission volume, improve the data transmission efficiency, and save network bandwidth resources.

[0015] In some possible implementation manners, the step of collecting vehicle signals of the target vehicle includes the following steps:

[0016] Obtain the identification information of the target vehicle;

[0017] According to the identification information, determine the type of vehicle signals to be collected. The type of vehicle signals includes driving mileage, cruising range, average fuel consumption, or vehicle speed;

[0018] Collect the vehicle signals according to the type of vehicle signals to be collected.

[0019] It can be seen that the vehicle signal collection strategy obtained in the embodiment of the present application is configured on demand. The vehicle signals in the collection strategy correspond to the vehicle identification information, and there will be no redundant or vehicle signals that the target vehicle does not have, making the collection of vehicle signals more targeted, thereby improving the collection efficiency of vehicle signals.

[0020] In some possible implementation manners, before the step of comparing the vehicle signals with the previously reported vehicle signals to obtain incremental signals, the following steps are further included:

[0021] In response to the failure of vehicle signal acquisition, upload a signal anomaly message to the server, where the signal anomaly message is used to indicate the anomaly of vehicle signal acquisition; or

[0022] In response to the successful acquisition of the vehicle signal, execute the step of comparing the vehicle signal with the previously reported vehicle signal to obtain an incremental signal.

[0023] It can be seen that if the in-vehicle terminal detects the failure of vehicle signal acquisition, it reports a signal anomaly message to the server to prompt the server that there are anomalies in some vehicle signal acquisitions, which is convenient for the server to process the signal anomaly messages with acquisition failures subsequently.

[0024] In some possible implementation manners, generating an incremental signal message according to the incremental signal and the signal identifier corresponding to the incremental signal includes the following steps:

[0025] Determine the type of the incremental signal according to the signal identifier corresponding to the incremental signal;

[0026] Determine the reporting order and byte length of the incremental signal according to the type of the incremental signal;

[0027] According to the byte length, perform format conversion on the incremental signal to obtain a reporting message body;

[0028] Combine the reporting message bodies according to the reporting order to obtain an incremental signal message.

[0029] It can be seen that generating an incremental signal message according to the incremental signal and the signal identifier corresponding to the incremental signal can make the message generation strategy of vehicle signals simpler and more flexible.

[0030] In some possible implementation manners, the method includes the following steps:

[0031] If the number of times when there is no incremental signal in the comparison between the vehicle signal and the previously reported vehicle signal reaches a preset threshold, adjust the reporting frequency so that the adjusted reporting frequency is less than the preset reporting frequency.

[0032] It can be seen that when it is determined that the number of times when there is no incremental signal reaches the preset threshold, adjusting the reporting frequency so that the adjusted reporting frequency is less than the preset reporting frequency can avoid the problem of waste of network bandwidth resources caused by the too fast reporting frequency and the vehicle signal not having time to change.

[0033] In a second aspect, an embodiment of the present application provides another data transmission method, including the following steps:

[0034] Receive an incremental signal message;

[0035] Parse the incremental signal message to obtain the signal identifier corresponding to the incremental signal;

[0036] Obtain the incremental signal according to the signal identifier corresponding to the incremental signal.

[0037] It can be seen that the embodiments of the present application only need to process the incremental signal, which greatly improves the efficiency of data processing and saves network bandwidth resources at the same time.

[0038] In a third aspect, an embodiment of the present application provides a data transmission device, including the following parts:

[0039] An acquisition module, configured to acquire vehicle signals of a target vehicle, where one signal in the vehicle signals corresponds to one signal identifier, and the signal identifier is used to determine the type of the vehicle signal;

[0040] A comparison module, configured to compare the vehicle signal with the previously acquired vehicle signal to obtain an incremental signal;

[0041] A generation module, configured to generate an incremental signal message according to the incremental signal and the signal identifier corresponding to the incremental signal;

[0042] A reporting module, configured to report the incremental signal message to a server.

[0043] In a fourth aspect, an embodiment of the present application provides another data transmission device, including the following parts:

[0044] A receiving module, configured to receive an incremental signal message;

[0045] An analysis module, configured to analyze the incremental signal message to obtain the signal identifier corresponding to the incremental signal;

[0046] An obtaining module, configured to obtain the incremental signal according to the signal identifier corresponding to the incremental signal.

[0047] In a fifth aspect, an embodiment of the present application provides a computer device, including a processor, a memory, and a communication interface, where the memory stores one or more programs, which are configured to be executed by the processor, and the programs are instructions for performing some or all of the steps described in the first aspect and the second aspect.

[0048] In a sixth aspect, an embodiment of the present application provides a computer-readable storage medium, where the computer-readable storage medium stores a computer program, and the computer program enables a computer to execute to implement some or all of the steps described in the first aspect and the second aspect.

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0057] The terms "first", "second", "third", "fourth", etc. in the specification, claims and drawings of the present application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products or devices.

[0058] References to "embodiments" in this specification mean that a particular feature, result, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment each time, nor are they independent or alternative embodiments mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0059] To better understand the technical solutions of the embodiments of the present application, the system architecture that the embodiments of the present application may involve will be introduced first. Please refer to Figure 1 , a schematic diagram of a system architecture provided by an embodiment of the present application. The system architecture may include: an in-vehicle terminal 100 and a server 200. The in-vehicle terminal 100 and the server 200 can communicate with each other through a network. The network communication can be based on any wired and wireless networks, including but not limited to the Internet, wide area network, metropolitan area network, local area network, virtual private network (VPN), and wireless communication network, etc.

[0060] The in-vehicle terminal 100, also known as an in-vehicle device, in-vehicle computer, or car head unit. In the embodiments of the present application, it can be used to collect vehicle signals, generate signal messages from the vehicle signals, and communicate with the server 200, specifically for reporting the signal messages to the server 200.

[0061] The in-vehicle terminal 100 may include a processor, a memory, a communication interface, and a bus. The processor, memory, and communication interface can be interconnected with each other through the bus. Among them, the memory can be used to store software programs and data. The processor can execute various functional applications and data processing of the in-vehicle terminal 100 by running the software programs and data stored in the memory. In the embodiments of the present application, the processor can be used to collect vehicle signals. The communication interface can be used to communicate with the server 200, for example, reporting signal messages to the server 200.

[0062] The telematics box (T-box or also known as TCU) is a very important component in the in-vehicle terminal 100, mainly used for communication between the outside of the vehicle and the server and other terminals (such as mobile phones). The T-box can obtain data of each electronic control unit (ECU) through the controller area network (CAN) bus, such as vehicle condition reports, driving reports, fuel consumption statistics, traffic violation inquiries, location tracks, driving behaviors, etc., and transmit the data to the server through the network to achieve real-time monitoring of the vehicle, or facilitate subsequent testing of the vehicle's performance and analysis of the user's driving behavior.

[0063] It should be noted that the vehicle terminal 100 may further include devices not involved above. For example, a vehicle computing unit, a Bluetooth module, an audio module, a video module, a battery system, a map module, and other possible functional modules, which will not be elaborated here.

[0064] The server 200 may be a single server or a server cluster composed of multiple servers. In the embodiments of the present application, the server 200 can communicate with the vehicle terminal 100. Specifically, it can be used to receive the incremental signal message sent by the vehicle terminal 100, and can also be used to parse the incremental signal message to obtain the incremental signal. The server 200 can be a cloud server, a vehicle networking cloud platform, a vehicle networking cloud server, an Internet of Things device, a data center network device, a cloud computing device, a computer supporting the 802.11 protocol, and network devices in a future evolved public land mobile network (PLMN), etc. The embodiments of the present application do not make specific limitations.

[0065] It can be understood that Figure 1 The system architecture shown is only an exemplary implementation manner in the embodiments of the present application. The system architecture in the embodiments of the present application includes but is not limited to the above system architecture.

[0066] Currently, new energy vehicles mainly use the national standard 32960 protocol or the ministry standard 808 protocol, etc. to complete data reporting. These protocols usually use full-volume reporting, that is, all data collected by the vehicle needs to be reported. In the case of too many signal volumes, it is easy to cause waste of network resources.

[0067] In view of this, the embodiments of the present application provide a data transmission method, device, computer device, and storage medium, aiming to improve data transmission efficiency and save network bandwidth resources.

[0068] Combined with the above system architecture, a data transmission method provided by the embodiments of the present application will be described below. Please refer to Figure 2 , Figure 2 is a flowchart of a data transmission method provided by the embodiments of the present application. As Figure 2 shown, taking the vehicle terminal as the execution subject of the method as an example for illustration, the method may include steps S201 - step S204.

[0069] Step S201: The vehicle terminal collects vehicle signals of the target vehicle.

[0070] In the embodiments of the present application, the target vehicle is the vehicle for which vehicle signals are to be collected. The vehicle signals may include control data and driving data generated during the operation of the target vehicle. For example, driving mileage, cruising range, average fuel consumption, vehicle speed, remaining battery power, and so on. The vehicle signals may also include position information, remaining fuel, air-conditioning temperature, side light status, and so on, or other operation data that can reflect the status of the target vehicle, which is not limited herein. It can be understood that each vehicle signal includes at least a signal name and a corresponding status value. For example, if the vehicle signal is the remaining battery power, the corresponding status value may be 80%.

[0071] In the embodiments of the present application, one signal in the vehicle signals corresponds to one signal identifier, and this signal identifier is used to determine the type of the vehicle signal. By way of example, the signal identifier for driving mileage may be "0x7E01", and the signal identifier for cruising range may be "0x7E02". Conversely, "0x7E01" may represent driving mileage, and "0x7E02" may represent cruising range. That is to say, each vehicle signal has a unique signal identifier, and the type of the vehicle signal can be determined according to the signal identifier.

[0072] In some possible implementation manners, collecting the vehicle signals of the target vehicle specifically includes the following steps: obtaining the identification information of the target vehicle; determining the type of the vehicle signals to be collected according to the identification information, where the type of the vehicle signals includes driving mileage, cruising range, average fuel consumption, or vehicle speed; and collecting the vehicle signals according to the type of the vehicle signals to be collected.

[0073] In the embodiments of the present application, the identification information may be a vehicle identification number (VIN), or a license plate number, or other identifiers representing the vehicle identity. It can be understood that each target vehicle has a unique VIN and a unique license plate number. According to the identification information of the target vehicle, the vehicle type of the target vehicle is identified, and the type of the vehicle signals to be collected is determined, so that the vehicle signals required by the target vehicle can be known.

[0074] By way of example, the data structure defines 80 types of vehicle signals. The in-vehicle terminal obtains the VIN of the target vehicle through an in-vehicle network (such as a CAN network). According to the VIN, it is determined that there are 60 types of vehicle signals to be collected for the target vehicle. Then, the in-vehicle terminal only specifically collects 60 vehicle signals of the target vehicle, and does not collect the remaining 20 vehicle signals that do not exist for the target vehicle. It can be seen that the vehicle signal collection strategy obtained in the embodiments of the present application is configured on demand. The vehicle signals in the collection strategy correspond to the identification information, and there will be no redundant or non-existent vehicle signals for the target vehicle, making the collection of vehicle signals more targeted, thereby improving the collection efficiency of vehicle signals.

[0075] Step S202: The in-vehicle terminal compares the vehicle signal with the previously reported vehicle signal to obtain an incremental signal.

[0076] In the embodiment of the present application, the incremental signal is the vehicle signal with changed data when the vehicle signal collected this time is compared with the previously reported vehicle signal. For example, in the vehicle signal collected this time, the driving mileage is 35 km and the remaining battery power is 98%. In the previously reported vehicle signal, the driving mileage is 30 km and the remaining battery power is 98%. It can be understood that compared with the previously reported vehicle signal, among the collected vehicle signals, the data of the driving mileage has changed, while the data of the remaining battery power has not changed. Then the incremental signal is only the driving mileage. For example, if 80 vehicle signals are successfully collected this time and 60 vehicle signals have changed compared with the previously reported vehicle signal, then the incremental signal is 60.

[0077] In some possible implementation manners, before performing step S202, the following steps may further be included: in response to the failure of collecting the vehicle signal, uploading a signal exception message to the server, where the signal exception message is used to indicate the exception of collecting the vehicle signal.

[0078] In the embodiment of the present application, the failure of collecting the vehicle signal may mean that no data is collected for one or more signals to be collected, or it may mean that the data collected for one or more signals to be collected is abnormal. For example, the data of the remaining battery power is usually 0-100%, and if the remaining battery power is collected as 120%, then the data of the remaining battery power is abnormal at this time. For example, if there are 80 vehicle signals to be collected for the target vehicle and only 60 are successfully collected this time, and the remaining 20 vehicle signals fail to be collected. For the vehicle signals that fail to be collected, the signal exception message may be set to "0000", and the in-vehicle terminal uploads the signal exception message to the server.

[0079] It can be seen that if the in-vehicle terminal detects the failure of collecting the vehicle signal, it reports a signal exception message to the server to prompt the server that some vehicle signals are abnormally collected, which is convenient for the server to process the signal exception message of the failed collection subsequently.

[0080] Optionally, if the in-vehicle terminal detects that the collected signal data is abnormal, it may also directly delete the abnormal data to save storage space.

[0081] In some possible implementation manners, if the number of times that there is no incremental signal when the vehicle signal is compared with the previously reported vehicle signal reaches a preset threshold, the reporting frequency is adjusted so that the adjusted reporting frequency is less than the preset reporting frequency.

[0082] Exemplarily, the preset reporting frequency of the remaining power is once every 3 seconds, and the number of times there is no incremental signal reaches the preset threshold (assumed to be 5 times). That is to say, the data of the remaining power has not changed for 5 consecutive times. At this time, the reporting frequency is adjusted so that the adjusted reporting frequency is less than the preset reporting frequency. For example, the reporting frequency of the remaining power is adjusted from the preset once every 3 seconds to once every 5 seconds.

[0083] It can be seen that when it is determined that the number of times there is no incremental signal reaches the preset threshold, adjusting the reporting frequency so that the adjusted reporting frequency is less than the preset reporting frequency can avoid the problem of waste of network bandwidth resources caused by the reporting frequency being too fast and the vehicle signal not having time to change.

[0084] It should be noted that the reporting frequencies of each vehicle signal can be the same or different, and the present application does not make any limitations in this regard. The specific values are set by technicians according to the actual situation.

[0085] Step S203: The in-vehicle terminal generates an incremental signal message according to the incremental signal and the signal identifier corresponding to the incremental signal.

[0086] In some possible implementation manners, generating an incremental signal message according to the incremental signal and the signal identifier corresponding to the incremental signal may include the following steps: determining the type of the incremental signal according to the signal identifier corresponding to the incremental signal; determining the reporting order and byte length of the incremental signal according to the type of the incremental signal; performing format conversion on the incremental signal according to the byte length to obtain a reporting message body; and combining the reporting message bodies according to the reporting order to obtain an incremental signal message.

[0087] The embodiments of the present application use a custom protocol to report vehicle signals. The data structure of the reporting message body can be referred to in the following table. Among them, one signal identifier corresponds to one vehicle signal. Exemplarily, if the data structure defines 80 types of vehicle signals, then the signal identifiers can be "0x7E01, 0x7E02, 0x7E03... 0x7E4F, 0x7E50". The byte length is determined according to the data length of the vehicle signal. The larger the data length of the vehicle signal, the larger the byte length. For example, the byte length of the driving mileage is 4 bytes; conversely, if the data length of the vehicle signal is smaller, the byte length of the remaining fuel amount is represented by 1 byte.

[0088] It should be noted that the signal identifiers in the data structure shown in the following table are only examples. In the embodiments of the present application, only one vehicle signal corresponds to one signal identifier, and the format of the signal identifier is not limited. It can be other permutations and combinations of numbers, letters, or symbols, and this is not limited. The vehicle signal types in the embodiments of the present application may include, but are not limited to, the vehicle signal types listed in the following table. In some possible implementation manners, it may also include vehicle speed, remaining power, location information, air-conditioning temperature, side light status, etc., or other operating data that can reflect the state of the target vehicle, which is not limited here, and the corresponding data structure can refer to the following table.

[0089] Signal identifier Byte length Vehicle signal Data type 0x7E01 4 Driving mileage byte 0x7E02 2 Endurance mileage byte 0x7E03 1 Remaining fuel byte … … … …

[0090] Exemplarily, the obtained incremental signal is the driving mileage, and the corresponding status value is 1222 km. The signal identifier corresponding to the driving mileage is "0x7E01", and the byte length is 4 bytes. If a hexadecimal message is selected, then the incremental signal message can be "7E01000004c6". In the embodiments of the present application, the message takes hexadecimal as an example, and octal and binary can also be used, which is not limited here. Among them, "0x" in the signal identifier indicates that hexadecimal numbering is used, and it can be omitted in the message.

[0091] Exemplarily, the obtained incremental signals are the driving mileage and the remaining fuel. The status value corresponding to the driving mileage is 1222 km, and the status value corresponding to the remaining fuel is 69 L. According to the byte length of the type of the incremental signal, the incremental signal is format-converted to obtain the reported message body. Here, the reported message body of the driving mileage can be "7E01000004c6", and the reported message body of the remaining fuel can be "7E0345". Then, according to the reporting order (exemplarily, the reporting order can be in the order of the signal identifier), the reported message bodies are combined to obtain the incremental signal message "7E01000004c67E0345".

[0092] In some possible implementation manners, the reported message bodies can also be reported in any combination. The incremental signal message of the driving mileage and the remaining fuel can also be "7E03457E01000004c6". It can be seen that adopting the above incremental signal message generation strategy is simpler and more flexible compared to the national standard 32960 protocol or the ministry standard 808 protocol.

[0093] In some possible embodiments, the incremental signal message may further include identification information of the target vehicle, and the identification information may include, but is not limited to, information such as VIN, license plate number, etc. that can identify the identity of the target vehicle. In the embodiments of the present application, the identification information of the target vehicle can be used as the header of the incremental signal message. When the server parses the message, it can quickly identify the identity of the target vehicle, which is convenient for classifying and organizing data or subsequent calls to test the performance of the vehicle and analyze the driving behavior of users.

[0094] Step S204: The in-vehicle terminal reports the incremental signal message to the server.

[0095] The in-vehicle terminal reports the incremental signal message to the server through the T-box for the server to read and analyze the reported incremental signal data. Optionally, when the in-vehicle terminal collects vehicle signal data, it can also store the collected vehicle signal data in the in-vehicle terminal to facilitate the in-vehicle terminal to use the stored vehicle signal data for other processing.

[0096] It can be seen that the in-vehicle terminal reports vehicle signal data to the server by adopting the incremental reporting method, that is, reports the vehicle signals with changed collected data, and does not report the unchanged data. This can reduce the data transmission volume, improve the data transmission efficiency, and save network bandwidth resources.

[0097] Combined with the above system architecture, another data transmission method provided by the embodiments of the present application will be described below. Please refer to Figure 3 , Figure 3 is a schematic flowchart of another data transmission method provided by the embodiments of the present application. As Figure 3 shown, taking the execution subject of the method as the server as an example for illustration, the method may include step S301, step 302, and step S303.

[0098] Step S301: The server receives the incremental signal message.

[0099] Step S302: The server parses the incremental signal message to obtain the signal identifier corresponding to the incremental signal.

[0100] Step S303: The server obtains the incremental signal according to the signal identifier corresponding to the incremental signal.

[0101] Specifically, after receiving the incremental signal message sent by the in-vehicle terminal, the server parses the incremental signal message. In the embodiments of the present application, the signal identifier of the incremental signal can be obtained from the incremental signal message, and the signal identifier is used as a query index to determine the type of the incremental signal. Then, the byte length is determined according to the type of the incremental signal, and further the parsing of the incremental signal message is completed to obtain the incremental signal and the corresponding data. The server can store, forward, or perform other processing on the obtained incremental signal and the corresponding data, which is not limited herein.

[0102] For the reference description of the signal identifier, reference can be made to the foregoing definition, which will not be elaborated herein. It can be seen that in the embodiments of the present application, the server only needs to process the incremental signal, which greatly improves the data processing efficiency and saves network bandwidth resources at the same time.

[0103] In some possible implementation manners, if the server identifies that the message is a signal exception message, the message can be discarded to save network resources.

[0104] Optionally, the server can also obtain the identification information of the target vehicle from the incremental signal message, and can quickly identify the identity of the target vehicle according to the identification information, which is convenient for classifying and organizing the incremental data or subsequent calls to test the performance of the vehicle and analyze the driving behavior of the user.

[0105] The method of the embodiments of the present application is elaborated in detail above, and the device of the embodiments of the present application is provided below.

[0106] Please refer to Figure 4 , Figure 4 which is a schematic structural diagram of a data transmission device provided by the embodiments of the present application. As Figure 4 shown, when the data transmission device is an in-vehicle terminal, the data transmission device 400 includes:

[0107] An acquisition module 401, configured to acquire vehicle signals of a target vehicle, where one signal in the vehicle signals corresponds to one signal identifier, and the signal identifier is used to determine the type of the vehicle signal;

[0112] In some possible embodiments, the data transmission device 400 further includes a judgment module 405, configured to determine whether the vehicle signal is acquired successfully. If so, the comparison module 402 is called. If not, the reporting module 404 is called to execute the step of uploading a signal exception message to the server, where the signal exception message is used to indicate that the acquisition of the vehicle signal is abnormal.
