Abstract

The invention provides a high precision launching platform switching device control system comprising an upper computer, a control box, a transfer box and collection and feedback devices. Each collection and feedback device comprises a hydraulic box and a displacement sensor, wherein the hydraulic box is used for providing an electro-hydraulic servo structure, receiving control data to form stepping control signals, controlling the valve port flow of the corresponding electromagnetic valves and forming power output working on execution mechanisms of switching devices, and the displacement sensor is used for measuring the real-time signals such as the displacement and the speed of the switching devices and outputting the signals. The invention also provides a corresponding control method. The control method employs a feedback closed-loop control mode to perform speed control on various switching devices and prevents influence from unpredictable external factors; the calculation, feedback and regulation speeds are high and the motion speed can be controlled in real time, so that repeated adjustment caused by lagging is reduced.

Description

technical field [0001] The invention relates to an electromechanical control system and method, in particular to an electromechanical control system and method for state transition of a large-tonnage platform. Background technique [0002] In order to ensure the smooth and safe state transition process of the launch platform between the load-bearing state of the platform wheel set and the load-bearing state of the conversion device, it is necessary to ensure that the force of each supporting device is always uniform during the lifting process, which directly affects the levelness of the main frame of the platform and its The force situation will affect the vertical state of the platform support. How to ensure that the deviation between the actual stroke and the theoretical stroke is less than ±0.5mm when the switching device adjusts the support state, that is, the support surfaces of each device are always on the same plane as much as possible requires careful design and opt...
