Automatic guided vehicle fault monitoring and tracing method and system

The invention relates to an automatic guided vehicle fault monitoring and tracing method and system. The method comprises the following steps: acquiring upper and lower limit thresholds of running state data when a vehicle runs normally; acquiring real-time running state data of the vehicle and comparing the real-time running state data with a threshold value; and when the real-time running state data of the vehicle reaches a threshold value, acquiring current position information of the vehicle, shooting and recording videos of the vehicle and the surrounding environment of the vehicle and storing the videos, and meanwhile, storing the real-time running state data of the vehicle from the moment until the real-time running state data of the vehicle is recovered to a normal value or the vehicle fails to give an alarm and shut down. According to the method, the running state of the vehicle can be monitored in real time, the vehicle and the surrounding environment of the vehicle are shot, recorded and stored whe
