The invention provides a hydraulic control system, method and device and a working machine. The hydraulic control system comprises a handle, a main valve, a main pump and a controller, wherein the handle is used for obtaining the control input of a user; the main valve is provided with a first output end used for supplying hydraulic oil to an executing mechanism; the main pump is provided with a second output end used for outputting hydraulic oil, and the second output end communicates with the input end of the main valve; and the handle, the main valve and the main pump are all electrically connected with the controller, and the controller is arranged to control the first output flow of the main valve and the second output flow of the main pump based on the control input. According to the hydraulic control system, method and device and the working machine, the controller is arranged in the hydraulic system and can control the output flow of the main valve and the output flow of the main pump according to the control input of the handle, so that flow control over the main valve and the main pump is achieved through the transmission of electric signals, the hydraulic control precision can be improved, and the control efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of working machinery, in particular to a hydraulic control system, method, device and working machinery. Background technique [0002] The function of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components (accessories) and hydraulic oil. Hydraulic systems can be divided into two categories: hydraulic transmission systems and hydraulic control systems. Due to its unique advantages, that is, a wide range of process adaptability, excellent control performance and relatively low cost, the hydraulic system has been more and more widely used in various fields. In the application process of the hydraulic system, it is necessary to control the hydraulic pressure of the hydraulic system. [0003] In the current way of controlling hydraulic pressure, the signal is transm...
