The invention provides a vehicle top cover state identification method and device. The method comprises the steps of starting timing and acquiring the voltage at the two ends of a motor and the current flowing through the motor real time when the motor is started, determining whether the voltage at the two ends of the motor and the current flowing through the motor obtained in real time are abnormal or not; turning off the motor if any one of the voltage and the current is abnormal, determining whether the voltage at the two ends of the motor meets the preset voltage condition or not after a preset time length, and whether the current flowing through the motor meets the preset current condition or not; and if yes, determining that the vehicle top cover is closed, otherwise, determining that the vehicle top cover is not closed. The state of the top cover of a vehicle is judged according to the working parameters of a motor. Therefore, the monitoring of the state of the vehicle top coverbecomes simple and feasible, and the problem that a sensor is easy to damage is avoided.
Description
technical field [0001] The invention relates to the technical field of vehicle transportation, in particular to a vehicle roof state recognition method and device. Background technique [0002] The roof of the muck truck must be covered during transportation, otherwise it may cause the muck to be scattered along the road and loaded beyond the compartment, etc. The supervision of the status of the roof of the muck truck is a very important task for the management of muck trucks. [0003] The current common practice is to use the detection switch or the proximity sensor to judge whether the top cover is closed, but these two methods are easy to damage during the operation of the muck truck, and it is also easy to cheat, which makes the installation and maintenance in the early stage inconvenient , resulting in high cost. [0004] There is a method in the prior art, which can avoid the use of a detection switch, and only needs to replace the motor controller. The switch of th...
