The invention relates to the technical field of
safety control, and particularly discloses a
safety control method, device and
system for a
combine harvester, and the method comprises the steps: judging whether the
combine harvester meets a starting condition or not based on the position of a
handle of the
combine harvester, and the rotating speed value, the
battery voltage value and the excitation
voltage value of an engine of the combine harvester; and after the combine harvester meets the starting condition, if a
target control signal of a main
clutch of the combine harvester is received, and the combine harvester meets a preset condition corresponding to the
target control signal, the main
clutch is controlled. The method can effectively solve the potential safety
hazard caused by the fact that the vehicle starting condition is judged only by depending on the position of a
handle in the prior art, makes up for the defect that multi-dimensional
verification is not carried out in combination with the engine state, and can prevent illegal vehicle starting caused by sensor faults or instantaneous misoperation. And meanwhile, the problem that wrong actions are executed when a combination
signal is triggered by mistake before the combine harvester is started is avoided, and the
operation safety and the equipment reliability of the combine harvester are improved.
