[CN 202010369077.1] Hydraulic Cylinder Piston Stroke Control Method, Equipment, System and Hydraulic Machinery Title: Hydraulic Cylinder Piston Stroke Control Method, Equipment, System and Hydraulic Machinery Application Number: CN 202010369077.1 Applicant: Zoomlian Heavy Science Co., Ltd. Application Date: 2020-4-27 Patent Type: Invention Application The embodiment of the present invention provides a hydraulic cylinder piston stroke control method, which belongs to the field of hydraulic control, the piston is driven by hydraulic pump power conducted by hydraulic oil, and the method includes: obtaining a working condition parameter of the hydraulic pump in a piston stroke; determining a predicted stroke of the piston based on the working condition parameter; and controlling an action of the piston based on a relationship between the predicted stroke and a set stroke threshold of the piston. At the same time, a hydraulic cylinder piston stroke control device and system are also disclosed. The embodiment of the present invention solves the problem that the hydraulic system cannot work normally caused by the situation that the position of the hydraulic piston cannot be obtained, and at the same time improves the stability of the hydraulic system.
