Large-scale high-precision passive air-floating vibration isolation platform integrated control cabinet

Abstract

The invention discloses a large-scale high-precision passive air-floating type vibration isolation platform integration control cabinet, which comprises a switch region and a diagnosis region. The switch region comprises a main switch-on button (ON), a main switch-off button (OFF), a pressure regulating button and an instrument panel; the main switch-on button (ON) is used for integrally inflatingthree groups of springs of an air-floating platform; the main switch-off button (OFF) is used for stopping integrally inflating the three groups of springs of the air-floating platform; the pressureregulating button is used for integrally setting and regulating air pressure values of the three groups of springs; the diagnosis region comprises three groups of air exhaust buttons and an instrumentpanel; the three groups of air exhaust buttons independently control air exhaust of three groups of air sources; and each group of air exhaust buttons comprises a high-grade air exhaust button (H), amiddle-grade air exhaust button (M), a low-grade air exhaust button (L) according to exhaust velocities.

Description

technical field [0001] The invention relates to the technical field of vibration control, in particular to a large-scale high-precision passive air-floating vibration-isolation platform integrated control cabinet. Background technique [0002] At present, for the vibration isolation control of large-scale high-precision air-floating platforms, manual inflation, debugging, and maintenance of the platform’s vibration-damping springs are mostly used, which is time-consuming, labor-intensive, and inefficient, or some simple control systems are used for control, but It lacks supporting fault diagnosis auxiliary functions. In summary, traditional engineering methods have the following defects: [0003] (1) There is no supporting control cabinet, which is not convenient for management and control. There are many problems with manual control methods. First of all, the manual method of controlling the vibration isolation platform needs to charge and deflate the air springs one by ...

Problems solved by technology

[0003] (1) There is no supporting control cabinet, which is not convenient for management and control

There are many problems with manual control methods

First of all, the manual method of controlling the vibration isolation platform needs to charge and deflate the air springs one by one, and debug them one by one, which is time-consuming, laborious and inefficient. control; finally, when the platform fails, it is not easy to repair and troubleshoot

[0004] (2) Lack of auxiliary functions for fault diagnosis

The existing control system lacks auxiliary functions for fault diagnosis, which brings great inconvenience to the maintenance of the system. Fault diagnosis sometimes requires checking each group of springs, recording data under different air pressures, and repeatedly testing and comparing. The method is not only cumbersome, but sometimes due to a wrong step in the diagnosis process, the test data will be invalidated, and the problem cannot be found out in time, the efficiency is low, and error-prone
