Vibrating wire sensor acquisition system, method and device based on wireless sensor network

Abstract

The invention belongs to the technical field of communication and measurement of wireless sensor network, and discloses a vibrating wire sensor acquisition system, method and device based on the wireless sensor network. The vibrating wire sensor acquisition system based on the wireless sensor network comprises an embedded processor module, a sensor excitation and measurement module, a wireless sensor network module and a power supply module. According to the vibrating wire sensor acquisition system, method and device based on the wireless sensor network, the nearby installation of a sensor isrealized, the bondage of a large number of cables can be rid of, interference and signal attenuation caused by long cables are eliminated, system construction cost and construction period are reduced,and a ''cable-free'' system is realized. The low power consumption design of an acquisition instrument can adopt batteries or solar energy for power supply, so that the limitation of alternating current power supply is avoided, alternating current dose not exist, power frequency interference on the alternating current and the introduction of lightning can be eliminated, and the reliability of thesystem is improved; and the acquisition instrument is small in size and made of metal, and adopts an embedded structure, both ends of the acquisition instrument are sealed and fixed by cover plates,and the acquisition instrument can be installed anywhere without providing additional protection.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network communication and measurement, and in particular relates to a vibrating wire sensor acquisition system, method and device based on a wireless sensor network. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: The characteristics of the safety monitoring system in water conservancy projects are that the sensors are distributed in a wide range and the environment is relatively harsh. The traditional monitoring method is to lead the sensor cables to the collection device, collect data through the collection device, and then use communication cables or other communication technologies to collect data. A means of transmission to the control center. There are a large number of signal cables and communication cables in this way, and cable trenches need to be excavated, which is time-consuming and laborious. It is easy to be ...

AI Technical Summary

Problems solved by technology

[0003] In summary, the problems in the prior art are: Existing collectors use a large number of working methods, and need to open cable trenches, which takes time and effort, damages the surface image of the project, and has a long construction period; in particular, a large number of cables have various interferences, which are easily attacked by lightning, causing system failures or even paralysis
