A kind of excavator environment adaptive control system and control method

Abstract

The invention discloses an excavator environment self-adaptive control system and control method, which can adjust both the static power matching of the system and the dynamic power matching of the system according to environmental parameters such as atmospheric pressure, so that the engine can better adapt to the load change. The control system includes an excavator main controller, an engine controller, an information acquisition unit and a control unit. The information acquisition unit includes an atmospheric pressure sensor, a hydraulic oil temperature sensor, an engine cooling water temperature sensor, an ambient temperature sensor and an air conditioning refrigeration state detection unit. The units include hydraulic oil cooling pump control unit, engine cooling water cooling pump control unit, air conditioning condenser cooling pump control unit, hydraulic oil direct return oil tank control unit, main pump I control unit and main pump II control unit, information collection unit and excavation The input port of the machine controller is connected, the control unit is connected with the output port of the excavator main controller, and the engine controller is connected with the excavator controller.

Description

technical field [0001] The invention relates to the technical field of hydraulic excavators, in particular to an excavator environment adaptive control system and a control method. Background technique [0002] Hydraulic excavators work in a wide range of geographic and temperature ranges, and often work in high altitude, high temperature, and alpine regions, requiring excavators to have necessary environmental adaptability. In the plateau environment, the engine not only reduces the power, but also reduces the responsiveness; and the ambient temperature indirectly affects the heat dissipation power by affecting the heat dissipation capacity of the excavator. When facing extreme temperatures, it is necessary to adjust the maximum (minimum) heat dissipation capacity and cooperate with it. Appropriate heat dissipation strategy can achieve better heat dissipation effect, and at the same time, it needs the cooperation of power matching strategy to give full play to the power of ...
