Machine flow automatic holding control system and method

The invention relates to the technical field of engineering machinery, and discloses a machine tool flow automatic holding control system and method.A flow holding function is selected to be in an open state on a monitor, and the flow holding function is opened; according to the actual requirement of the working condition, a sliding key of the handle is slid to the target position, and the needed target flow float = f is obtained; a rolling button is pressed down to activate a flow keeping function; the target flow is achieved by adjusting the current of the machine tool electromagnetic valve and the current of the main pump, so that the flow maintaining function is achieved. The method has the beneficial effects that after the flow maintaining function is activated, a driver can loosen the handle sliding key, and the machine tool can act according to the maintained flow, so that the driving fatigue is relieved, and the driving experience of the driver is greatly improved. 本发明涉及工程机械技术领域，公开了一种机具流量自动保持控制系统及方法，在
