Multi-axis hydraulic synchronization control system, method and device

Abstract

The invention discloses a multi-axis hydraulic synchronization control system, method and device, and belongs to the technical field of synchronization control. The system comprises a controller, a digital-to-analogue conversion module, at least two hydraulic proportional valves and position feedback devices the number of which is equal to the number of the hydraulic proportional valves; the controller is connected with each hydraulic proportional valve through the digital-to-analogue conversion module, and each hydraulic proportional valve can drive a hydraulic cylinder which is connected with each hydraulic proportional valve; each position feedback device is respectively connected with the controller, each position feedback device can detect the position of each hydraulic cylinder, andtransmits the detected position data to the controller; and the controller can control each hydraulic proportional valve according to the position data of each hydraulic cylinder transmitted by each position feedback device and by consulting the stored synchronization data of the controller. The multi-axis hydraulic synchronization control system has the advantages of simple structure, high synchronization precision and low cost, and can be used for solving the problems of low synchronization and high cost of the existing multi-axis hydraulic synchronization.

Description

technical field [0001] The invention relates to the field of synchronous control, in particular to a multi-axis hydraulic synchronous control system, method and equipment. Background technique [0002] At present, in some electromechanical controlled equipment, such as electromechanical controlled stages, synchronous cylinders or synchronous motors are often used to achieve synchronous control of lifting, but if the lifting stroke of the stage is long, the volume of the used synchronous cylinders or synchronous motors will be reduced. Larger and more expensive. In addition, the synchronous cylinder or the synchronous motor requires high processing precision, and there are problems such as internal leakage safety hazards and high maintenance costs. Contents of the invention [0003] Based on the problems existing in the above-mentioned prior art, the embodiment of the present invention provides a multi-axis hydraulic synchronous control system, method and equipment, withou...
