The invention belongs to the technical field of automobile communication, and discloses a law and regulation data acquisition terminal anti-dismantling alarm method which comprises the following steps: step 1, a vehicle is powered on for the first time, and main parts of the vehicle are started in sequence; step 2, identifying a fixed CAN message agreed by the law and regulation data acquisition terminal in the first power-on process of the vehicle instrument panel; step 3, judging whether the current vehicle is equipped with a regulation data acquisition terminal according to the identification result, and marking and storing the identification result; if the current vehicle is not assembled with the regulation data acquisition terminal, entering the step 7, otherwise, entering the next step; and 4, the vehicle instrument panel and the law and regulation data acquisition terminal carry out CAN message communication interaction at a fixed time interval, and fault-tolerant algorithm processing of anti-disassembly judgment is carried out on an interaction result. According to the invention, a driver can be obviously prompted of the current working state of the regulation data acquisition terminal, and the abnormal working state of the regulation data acquisition terminal caused by the fact that the driver cannot know non-subjective in the driving process is avoided.

    本发明属于汽车通信技术领域,公开了一种法规数据采集终端防拆除报警方法,包括以下步骤:步骤一、车辆首次上电,车辆的主要部件依次启动;步骤二、车辆仪表盘首次上电过程中,识别与法规数据采集终端约定的固定CAN报文;步骤三、根据识别结果判断当前车辆是否装配有法规数据采集终端,并对识别结果进行标记存储;若判断当前车辆未装配法规数据采集终端则进入步骤七,否则进入下一步;步骤四、车辆仪表盘与法规数据采集终端进行固定时间间隔的CAN报文通信交互,并对交互结果进行防拆判断的容错算法处理。本发明能够显著提示驾驶员当前法规数据采集终端的工作状态,避免驾驶员在行驶过程中无法得知非主观造成法规数据采集终端工作状态异常。
