Air bag vibration isolation device

Abstract

The invention discloses an intelligent air bag vibration isolation device which comprises a plurality of air bags, a height sensor and a pressure sensor are arranged outside the air bags, the height sensor comprises a probe, a front-end device and a cable, the probe and the front-end device are integrated together, and the height sensor is connected to an FF bus; the dust cover shell wraps the height sensor; the electromagnetic air inlet valve and the electromagnetic air outlet valve are arranged on the air bag air inlet pipe and the air outlet pipe and are connected with the FF bus; the pressure sensor is connected to the FF bus to detect the pressure of the air bag; the air bag controller is connected to the FF bus, receives data of the pressure sensor and the height sensor and controls the electromagnetic air inlet valve and the electromagnetic air outlet valve to conduct air inlet or air outlet. According to the invention, the preposition device and the probe of the height sensor are integrated together, so that the height detection precision is improved; and an FF bus architecture is adopted, software and hardware upgrading is facilitated, equipment of different manufacturers can be compatible, and an equipment diagnosis function is achieved.

Description

technical field [0001] The invention belongs to the technical field of ship vibration reduction, in particular to an airbag vibration isolation device. Background technique [0002] Ships using airbag vibration isolators can effectively reduce noise and improve stealth performance due to good low-frequency vibration isolation performance. However, due to the air leakage of the airbag or the vibration of the engine and propeller, the ship deviates from the centered state, which makes the pipeline connected to the detection distorted and reduces the vibration isolation effect. Therefore, it is necessary to effectively control the attitude balance of the equipment. The premise of maintaining posture balance is to effectively detect the height of the airbag. The eddy current displacement sensor used in the existing airbag vibration isolation, the probe and the front device are two separate parts, connected by an armored shielded cable in the middle, if the armored shielded cabl...

AI Technical Summary

Problems solved by technology

The eddy current displacement sensor used in the existing airbag vibration isolation, the probe and the front device are two separate parts, connected by an armored shielded cable in the middle, if the armored shielded cable is too long, it will affect the drive of the front device to the probe And signal reception, which affects the measurement accuracy of the height, which leads to inaccurate adjustment of the airbag height, and repeatedly adjusts the height of the airbag within a certain range, resulting in the reduction of the stealth effect and the life of the airbag

[0003] The attitude control of the airbag vibration isolator requires the use of a variety of sensors and actuators. With the traditional bus structure, it is difficult to upgrade the software and hardware of the bus equipment, and it cannot be compatible with equipment from different manufacturers. It does not have the online diagnosis function of the equipment and cannot achieve definite control. system
