CAN data acquisition method and system based on TBC file

The invention discloses a CAN data acquisition method and system based on a TBC file, relates to the technical field of new energy vehicle-mounted terminal data acquisition, and solves the technical problems of frequent terminal software upgrading and poor stability in the prior art. The method comprises the following steps: constructing a communication matrix based on a TBC file; the constructed communication matrix is updated; issuing the updated communication matrix; and after the issuing is successful, collecting CAN data of the vehicle-mounted end according to the updated communication matrix. According to the method, the CAN communication matrix is flexibly defined and changed through the TBC file, and terminal embedded software does not need to be changed; moreover, the system can be adapted to vehicles with various different CAN protocols for CAN data acquisition, and is high in applicability. 本发明公开了一种基于TBC文件的CAN数据采集方法及系统，涉及新能源车载终端数据采集技术领域，解决了现有技术中存在的终端软件升级频繁，稳定性变差的技术问题。本方法包括的步骤为：构建基于TBC文件的通信矩阵；对构建的通信
