[0037] In order to improve the accuracy of the pressure calibration of the overflow valve and reduce unnecessary energy waste of the hydraulic constant pressure system, the embodiments of the present invention provide a debugging control method, device, system and an engineering machine for overload protection. In this technical solution, the pressure of the hydraulic constant pressure system does not require manual visual inspection, the adjustment of the electric proportional relief valve is completed by electronic control, and the debugger only needs to manually input the opening adjustment information of the electric proportional relief valve. Therefore, The accuracy of the pressure calibration of the overflow valve is greatly improved. The present invention will be described in detail below with specific embodiments in conjunction with the drawings.
[0038] Such as figure 2 In the illustrated embodiment, the debugging control method for overload protection of the present i...
