Problems solved by technology

[0003] The purpose of the present invention is to provide a distributed wireless pressure feedback compensation type air-floating vibration control system to solve the existing vibration control system in the prior art that is not suitable for low-frequency vibration and sudden high-energy broadband impact vibration In some occasions, the structure is complex, the volume is large, the price is expensive, and it is not easy to maintain. There will be short-term lag in the elimination of the impact of sudden non-stationary vibration interference.

Abstract

The invention discloses a distributed wireless pressure feedback compensation type air floatation vibration control system which comprises at least two support rigid pre-buried plates which are uniformly distributed on the bottom surface of the rigid platform in a distributed mode, and integrated data wireless communication fast feedback devices are arranged below the support rigid pre-buried boards respectively. Each integrated data wireless communication fast feedback device comprises a pressure sensor, a data acquisition module, a power supply module and a wireless communication module respectively, and the integrated data wireless communication fast feedback devices are respectively in control connection with an electromagnetic valve through wireless communication modules. An air floating damping unit is arranged under the pressure sensor, and an air inlet and an air outlet are formed in the air floating damping unit respectively. The air inlet is located above the air outlet, anda concrete foundation pier is arranged below the air floating damping unit. The structure is reasonable, the size is small, the cost is low, and the maintenance is easy.

Description

technical field [0001] The invention relates to the technical field of air-floating vibration control, in particular to a distributed wireless pressure feedback compensation type air-floating vibration control system. Background technique [0002] At present, for the micro-vibration control of precision equipment with high requirements for environmental vibration, the air-floating passive control system and the active servo vibration control system are mainly used. During the working process of these two technologies, they are mainly oriented to the disturbance of stationary random vibration. For sudden non-stationary vibration disturbance, each has the following disadvantages: (1) The air-floating passive control system is not suitable for low-frequency vibration Occasions affected by impact and sudden high-energy broadband shock vibration. The basic frequency of the air-floating passive vibration control system is generally 1.5 ~ 3.0Hz, so for a specific type of project i...
