Low-power-consumption spliced wireless structure vibration monitoring system and method

Abstract

The invention provides a low-power-consumption spliced wireless structure vibration monitoring system and method. The low-power-consumption spliced wireless structure vibration monitoring system comprises a server unit, a battery compartment splicing unit, a transformer unit and an acquisition unit, wherein the acquisition unit comprises an acquisition splicing unit and an acquisition independent unit; the acquisition splicing unit and the acquisition independent unit respectively extract structure vibration detection signals, and send the acquired signals to the server unit in a wireless communication mode; the server unit is used for processing the vibration data, displaying the vibration waveform in real time and warning an abnormal working state; the battery compartment splicing unit is used for supplying power to the system without a fixed power supply; the transformer unit is used for adjusting power supply voltage; and the acquisition splicing unit is used for simultaneously measuring a plurality of measuring points, and the acquisition independent unit is used for measuring a single measuring point. The number of measurement points is flexibly configured, the size of the low-power-consumption spliced wireless structure vibration monitoring system is small after splicing, the power consumption is low, the collection channel density is large, the device is easy to deploy near a collection position, and the interference caused by an overlong collection line is reduced.

Description

technical field [0001] The invention relates to the field of structural vibration signal monitoring, in particular to a low-power splicing wireless structural vibration monitoring system and method. Background technique [0002] Structural vibration monitoring is an important way to obtain dynamic performance information such as structural frequency, damping, response, and modal, to diagnose faults, and to evaluate health status. It is widely used in structural monitoring of mechanical structures, transportation structures, and bridge construction structures. in the field. Traditional vibration monitoring systems and solutions have many disadvantages: [0003] 1. The traditional high acquisition frequency (such as above 400Hz) vibration acquisition and monitoring system transmission is mostly wired transmission and WIFI wireless transmission. Wired transmission will increase wiring and occupy space. Although WIFI wireless transmission reduces wiring, its power consumption...
