The invention discloses a monitoring method and device for abnormal restart of a vehicle-mounted instrument, and relates to the technical field of automobile data monitoring, and the monitoring method for the abnormal restart of the vehicle-mounted instrument comprises the steps: obtaining the reset state information of a main control chip of the vehicle-mounted instrument and the instrument state information of the vehicle-mounted instrument in real time; combining the obtained reset state information and instrument state information into a data unit; and storing the combined data unit for reading when needed. When the vehicle is started, the reset state of the vehicle-mounted instrument main control chip and the instrument state of the vehicle-mounted instrument are monitored, the obtained reset state information and instrument state information are periodically combined into the data unit, then the data unit is stored in the EEPROM, and when a technician checks the abnormal condition of the vehicle instrument, the data unit is stored in the EEPROM. The monitoring data in the EEPROM can be read at any time and analyzed, so that whether a fault is a whole vehicle problem or an instrument problem is judged, and the accuracy of judging the fault cause of abnormal restart of the vehicle-mounted instrument is improved. When a technician reads the data in the EEPROM, the data stored in the EEPROM can be increased or decreased according to actual needs, flexibility and convenience are achieved, and the efficiency that the technician judges fault causes is improved.

    本发明公开了一种车载仪表异常重启的监测方法及装置,涉及汽车数据监测技术领域,其中车载仪表异常重启的监测方法包括:实时获取车载仪表主控芯片的复位状态信息,以及车载仪表的仪表状态信息;将获取的复位状态信息和仪表状态信息组合成数据单元;对组合得到的数据单元进行存储,以供需要时进行读取。本发明在车辆启动时监控车载仪表主控芯片的复位状态和车载仪表的仪表状态,周期性地将获取的复位状态信息和仪表状态信息组合成数据单元,然后将数据单元存储在EEPROM中,技术人员在排查汽车仪表异常状况时,可以随时读取EEPROM中的监控数据,并对数据进行分析,进而判断故障是整车问题还是仪表问题,提高了判断车载仪表异常重启的故障原因的准确性。技术人员在读取EEPROM中的数据时,可以根据实际需要对EEPROM中存储的数据进行增减,灵活方便,提高了技术人员判断故障原因的效率。
