The invention relates to the field of engineering machinery, and provides a control method, device and system of an operation machine and the operation machine.The method is applied to a power management module in the operation machine.The method comprises the steps that a starting signal is received, a starting control loop is connected based on the starting signal, and the starting control loop is used for controlling a starting output loop to be connected when the starting control loop is connected; wherein the starting output loop is a power supply loop of a starting motor of the operation machine; the starting signal is generated and sent by a vehicle control unit of the operation machine based on the starting control signal; and after it is determined that the preset duration is reached, the starting machine output loop is disconnected. According to the invention, the risk that the starting motor is burnt down can be effectively reduced, and the starting safety is ensured.
Description
technical field [0001] The present invention relates to the technical field of construction machinery, and in particular, to a control method, device, system and work machine of a work machine. Background technique [0002] As an important productivity tool in the engineering industry, construction machinery is faced with extremely complex working conditions, and its operational safety has received great attention. At present, EFI diesel engines are mainly used in construction machinery. The traditional start-up protection is mainly concentrated on the protection of the control end. It is easy to cause the starter motor to be burned due to control failure, and the safety of start-up cannot be guaranteed. SUMMARY OF THE INVENTION [0003] In view of the problems existing in the prior art, the present invention provides a control method, device, system and work machine for a work machine. [0004] The present invention provides a control method for a work machine, which is ...
