Description

Pump distribution method and device and electronic equipment Technical Field The application relates to the technical field of engineering machinery, in particular to a pump distribution method and device and electronic equipment. Background In construction machines, it is common to use a large number of pumps, the number of pumps being dependent on the flow demand of the whole system and the type of pump. When the system works, the pump conveys hydraulic oil into the hydraulic circuit, and then the hydraulic oil is distributed through the hydraulic circuit to actuators such as an oil cylinder or a motor or an actuating mechanism. Because of the different volume flows and operating pressures of the different actuators, relatively large throttling losses may result. In order to eliminate these throttling losses, a separate hydraulic circuit can be provided for each actuator, but at the same time the number of pumps is increased considerably, or the flow of the pumps is distributed to the individual actuators via a valve system, ensuring that the individual hydraulic circuits are always separated, avoiding throttling losses due to different operating pressures. For example, a lookup table method used in the hydraulic system assigns pumps to the actuators based on an assignment pattern corresponding to the actions of the actuators, which is statically stored in the lookup table. However, in the related art, when operators continuously change to operate, the flow requirements of each actuator are continuously changed, and the allocation mode of the corresponding pump is continuously changed, so that the situation that the pumps allocated to the actuators are frequently switched may occur, and unnecessary switching processes are brought.
