For example, the preset configuration file is a configuration file in a JSON format, after the JSON configuration file is read by the vehicle-mounted T-BOX, the target message information needing to be collected, the collection frequency and the collection condition of the target message information are determined, and in the using process of the vehicle, the vehicle-mounted T-BOX determines whether the working condition of the vehicle meets the collection condition or not according to the vehicle _ status _ id parameter (the collection condition of the target message information) in the JSON configuration file; when the vehicle working condition meets the condition set in vehicle _ status _ id, bus message data corresponding to the vehicle is periodically acquired according to a frequency value set by msgcystlesleetime (acquisition frequency of target message information), and the vehicle message data is sent to a remote server in a preset message format. And when the vehicle working condition does not meet the condition set by the vehicle _ status _ id, the relevant bus message data is not collected and stored.
The preset message format may be a table format, and the contents of the table format may be as shown in table 1 below:
TABLE 1

In an embodiment, a certain size of space may be allocated in a memory (a preset memory) where power failure data is not lost, as an area to be uploaded of vehicle message data. When the vehicle state meets the acquisition condition of vehicle _ status _ id, vehicle message data are acquired and sent to the remote server, if it is determined that the vehicle-mounted T-BOX and the remote server (such as TSP) are disconnected due to network abnormality and the like, the acquired vehicle message data can be stored in the region to be uploaded of the vehicle-mounted T-BOX in a preset message format, and after the vehicle-mounted T-BOX and the remote server are restored to be connected, the vehicle message data stored in the region to be uploaded are sent to the remote server again, so that the function of reissuing the vehicle message data is realized, and the possibility of vehicle message data loss caused by network failure is reduced. When the storage space of the area to be uploaded is insufficient, the vehicle-mounted T-BOX can delete the oldest vehicle message data to store the newly generated vehicle message data according to the sequence of the storage time, so as to ensure the timeliness and the accuracy of the vehicle message data.
In an embodiment, in step S30, that is, the vehicle message data is sent to the remote server, so that the remote server parses the vehicle message data to obtain the vehicle data, which specifically includes the following steps:
s31: and determining the data transmission frequency and the bus data communication matrix through the configuration information.
After the vehicle message data is acquired, the vehicle-mounted T-BOX needs to determine the data transmission frequency and the version number of the bus data communication matrix through corresponding parameter data in the configuration information.
S32: and sending the vehicle message data to a remote server at a data sending frequency so that the remote server analyzes the vehicle message data according to the bus data communication matrix to obtain the vehicle data.
After determining the data transmission frequency and the bus data communication matrix through the configuration information, the vehicle-mounted T-BOX needs to transmit vehicle message data in a preset message format to the remote server at the data transmission frequency and transmit the version number of the bus data communication matrix to the remote server. The remote server receives the vehicle message data and the version number of the bus data communication matrix, determines the corresponding bus data communication matrix according to the version number of the bus data communication matrix, and then analyzes the vehicle message data by adopting the bus data communication matrix to obtain the vehicle data, so that the real-time monitoring of the vehicle data is realized.
For example, the vehicle-mounted T-BOX regularly packages vehicle message data collected and stored in an area to be uploaded into a sending data format by adopting a specified compression algorithm (which can be determined by configuration information of a preset configuration file) according to a time interval defined by an uploadsequence parameter (data sending frequency) in a JSON configuration file, specifies a service request through a communication protocol of the vehicle-mounted T-BOX and a TSP server, and uploads the packaged vehicle message data to the TSP server; and after receiving the vehicle message data, the TSP server analyzes the vehicle message data by using the corresponding bus communication matrix database to obtain vehicle state data, so that the vehicle data is monitored.

s11: and determining whether the preset configuration file needs to be subjected to version updating.
After the vehicle-mounted T-BOX is powered on and started, before bus message data on a vehicle are collected according to configuration information, the vehicle-mounted T-BOX needs to determine whether a preset configuration file stored in a self preset memory needs to be subjected to version updating.
For example, the vehicle-mounted T-BOX needs to determine whether the version number of the preset configuration file is the latest version number, and if the version number of the preset configuration file is the latest version number, it is determined that the version update of the preset configuration file is not needed; and if the version number of the preset configuration file is not the latest version number, determining that the version of the preset configuration file needs to be updated. When the preset configuration file is not temporarily stored in the vehicle-mounted T-BOX, the fact that the version of the preset configuration file needs to be updated is determined.
In this embodiment, determining whether the preset configuration file needs to be subjected to version update according to the version number of the preset configuration file is only an exemplary illustration, and in other embodiments, determining whether the preset configuration file needs to be subjected to version update may also be performed in other manners, which is not described herein again.
S12: and if the version needs to be updated, acquiring a target update file, and updating the preset configuration file according to the target update file.
After determining whether the preset configuration file needs to be subjected to version updating, if determining that the preset configuration file needs to be subjected to version updating, the vehicle-mounted T-BOX acquires a target updating file from a remote server, updates the preset configuration file according to the target updating file, so as to store the updated preset configuration file in a preset memory, and simultaneously deletes the original preset configuration file in the preset memory. After the preset configuration file is updated according to the target update file, the vehicle-mounted T-BOX can execute the updated preset configuration file, namely, the configuration information of the preset configuration file with the latest version can be read, and then bus message data on the vehicle is collected according to the configuration information with the latest version so as to obtain vehicle message data.
In one embodiment, after determining whether the preset configuration file needs to be subjected to version updating and acquiring a target updating file, the preset configuration file of the existing version is still executed in the current ignition cycle, and when the next ignition cycle of the vehicle starts, the preset configuration file is updated according to the target updating file, that is, the preset configuration file of the latest version is executed at the next ignition cycle of the vehicle, so that vehicle message data is acquired according to configuration information of the preset configuration file of the latest version, and the preset configuration file of the existing version is deleted at the same time, so that the updating time of the preset configuration file is reduced, and the timeliness and the integrity of vehicle data acquisition are ensured.

In an embodiment, taking a remote server as a TSP server as an example for explanation, as shown in fig. 4, in step S11, determining whether the preset configuration file needs to be version-updated specifically includes the following steps:
s111: and the vehicle-mounted T-BOX determines the version information of the preset configuration file and sends a version matching request to the TSP server according to the version information.
Before bus message data on a vehicle are collected according to configuration information, the vehicle-mounted T-BOX determines version information of a preset configuration file and sends the version information and a version matching request to a remote server so that the remote server can perform version matching according to the version information and the version information of the latest version of the preset configuration file.
S112: and the TSP server receives the version matching request, performs version matching on the version information in the version matching request and the latest version preset configuration file, and sends a reply message to the vehicle-mounted T-BOX according to the version matching result.
And after receiving the version matching request, the TSP server performs version matching on the version information in the version matching request and the version information of the latest version preset configuration file, and then sends a reply message to the vehicle-mounted T-BOX according to the version matching result. And if the version matching result is not matched, generating a reply message according to the unmatched version matching result. When the version matching result is that the configuration files are not matched, the reply message may further include file downloading information (such as a downloading address) of the latest version preset configuration file. And if the version matching result is matching, generating a reply message according to the matching version matching result. When the preset configuration file is not stored in the vehicle-mounted T-BOX temporarily, the version number of the preset configuration file is determined to be 0, and the version number 0 of the preset configuration file is sent to the remote server so that the remote server can carry out version matching.
In this embodiment, to obtain the version information quickly, the version information of the preset configuration file may be a version number in the configuration information of the preset configuration file, and in other embodiments, the version information of the preset configuration file may also be other information identifying the version of the preset configuration file, which is not described herein again.

In other embodiments, in order to facilitate the quick generation of the reply message, reduce the data processing amount of the remote server, and solidify the parameter format of the reply message, that is, whether the version matching result is matched or not, the reply message returned by the remote server includes parameters such as a download address, a private key, a public key, and an encrypted signature ciphertext, and the difference is that, when the version matching result is matched, the data corresponding to the parameters such as the download address, the private key, the public key, and the encrypted signature ciphertext is the actual data of the corresponding parameters, and the data corresponding to the download address is the actual download address of the latest version preset configuration file package, and the parameters such as the private key, the public key, and the encrypted signature ciphertext correspond to the actual encrypted information value; and when the version matching result is unmatched, the data corresponding to the parameters such as the download address, the private key, the public key, the encrypted signature ciphertext and the like are null values. The format of the explicit reply message in a fixed parameter form is convenient for the remote server to directly generate the reply message, so that the data volume can be reduced, meanwhile, when the vehicle-mounted T-BOX acquires the reply message returned by the remote server according to the version matching request, whether the corresponding parameter in the reply message is a null value or not can be directly read, and if the corresponding parameter is the null value, the file downloading information does not exist in the reply message; if the reply message is not null, determining that the file downloading information exists in the reply message, so that the version updating of the preset configuration file is determined to be needed directly according to the file downloading information, and the target updating file is obtained directly according to the file downloading information.
S115: and if the reply message contains file downloading information, the vehicle-mounted T-BOX determines that the version of the preset configuration file needs to be updated.
After determining whether the reply message contains the file downloading information or not, if the reply message contains the file downloading information, the vehicle-mounted T-BOX determines that the version of the preset configuration file needs to be updated; and if the reply message does not contain the file downloading information, the vehicle-mounted T-BOX determines that the version of the preset configuration file does not need to be updated.
