and the collected vehicle gateway acquires the diagnosis message and executes mirror image operation of opening the collected vehicle gateway.
6. The method of claim 5, wherein the invoking, by the application program, the diagnostic security validation algorithm encapsulated in the dynamic library via the set open API interface comprises:
and setting an open API interface in the application program, encrypting or packaging the diagnosis security verification algorithm, and generating a called dynamic library.
7. The method of claim 6, wherein uploading the collected vehicle data to a memory module of the mobile terminal for storage further comprises:
and uploading the vehicle bus data locally acquired by the application program to a remote data server through a network of the mobile terminal for storage and summarization.
8. The method of claim 7, further comprising querying and/or downloading collected vehicle data summarized by the data server for analysis and diagnosis.
9. A remote data acquisition system, the system comprising:
the sending module is used for sending a vehicle data acquisition instruction; the vehicle data acquisition instruction is sent by an embedded application program based on a mobile terminal, and the mobile terminal is in communication connection with the diagnosis equipment through a data connection line;
the execution module is used for acquiring and executing the vehicle data acquisition instruction;
the data acquisition module is used for reading the acquired vehicle data and uploading the acquired vehicle data to the storage module of the mobile terminal for storage; the collected vehicle data are read and uploaded through diagnostic equipment, and the diagnostic equipment is in communication connection with the vehicle through an OBD patch cord.
10. A remote data acquisition device, the device comprising:
the mobile terminal unit is used for communicating and connecting an application program in the mobile terminal with the diagnosis equipment through a data connecting wire, sending a vehicle data acquisition instruction and acquiring acquired vehicle data;
the diagnosis unit is used for the diagnosis equipment to be in communication connection with the collected vehicle through the OBD patch cord, acquiring a vehicle data collection instruction of an application program in the mobile terminal, executing the data collection instruction, reading the collected vehicle data through the diagnosis equipment, and uploading the read collected vehicle data to a storage module of the mobile terminal for storage through the diagnosis equipment.
11. A diagnostic system comprising a data server, a vehicle remote diagnostic background, a remote data acquisition system according to claim 9, and a remote data acquisition device according to claim 10, wherein:
the data server is used for uploading the vehicle bus data locally acquired by the application program to a remote data server through a network of the mobile terminal for storage and summarization;
the vehicle remote diagnosis background is used for inquiring and/or downloading collected vehicle data summarized by the data server for analysis and diagnosis.
12. An electronic device, comprising:
a memory for storing non-transitory computer readable instructions; and
a processor for executing the computer readable instructions such that the computer readable instructions when executed by the processor implement the method of any one of claims 1 to 8.
13. A computer readable storage medium comprising computer instructions which, when run on a device, cause the device to perform the method of any one of claims 1 to 8.
