Problems solved by technology
[0002] The working conditions of the excavator are complex and the environment is harsh, especially in the heat dissipation area, which is often accompanied by a large amount of dust and foreign matter due to air inhalation, which eventually falls on the radiator. If the heat dissipation effect of the whole machine is not cleaned in time, the heat dissipation effect of the whole machine will be significantly reduced, affecting the hydraulic system and power system. service life

The disclosure provides a dust removal control method, controller and system. The dust removal control method includes: judging whether the differential pressure data on both sides of the radiator reported by the differential pressure sensor is greater than a first threshold; if the differential pressure data is greater than the first threshold, sending a first instruction to the monitor so that the monitor can display warning information; After receiving the second instruction for dust removal sent by the monitor and input by the user, detect whether the safety joystick is in a safe state; if the safety joystick is in a safe state, send a third instruction to the engine so that the engine stops working; If the current speed of the engine is 0, the electromagnetic reversing valve is controlled to enter the dust removal working position, wherein in the dust removing working position, the oil inlet of the electromagnetic reversing valve is connected with the first port of the cooling motor, and the oil outlet of the electromagnetic reversing valve It communicates with the second port of the heat dissipation motor; start the engine so that the heat dissipation motor drives the heat dissipation fan to rotate in reverse to remove dust from the radiator.
Description
technical field [0001] The present disclosure relates to the control field, in particular to a dust removal control method, controller and system. Background technique [0002] The working conditions of the excavator are complex and the environment is harsh, especially in the heat dissipation area, which is often accompanied by a large amount of dust and foreign matter due to air inhalation, which eventually falls on the radiator. If the heat dissipation effect of the whole machine is not cleaned in time, the heat dissipation effect of the whole machine will be significantly reduced, affecting the hydraulic system and power system. service life. [0003] Radiator dust removal is usually done manually. During dust removal, the machine is turned off manually, the engine stops working, the reversing valve is manually switched to make the cooling motor enter and exit the oil circuit, and then the power is manually turned on, and the fan reverse command is selected through the m...
