Design of monitoring system based on vibrating wire sensor

In this paper, the vibrating wire pressure sensor is taken as an example to describe the working principle of the vibrating wire pressure sensor and the hardware design and function algorithm of the lower computer part in the monitoring system. This paper is designed to collect multi-channel pressure information to observe the geological pressure environment, use ARMA algorithm to predict the geological pressure trend, and realize wireless data communication. The main content is to use the vibrating wire sensor to collect pressure information to achieve multi-position force monitoring; the MCU embeds the ARMA algorithm, analyzes the data, and produces the prediction result; and uses the Internet of Things technology to transmit the data to the host computer system. The upper computer part will get the data combined with the actual situation to analyze and get the required information. Complete a monitoring system that meets actual needs. The monitoring system can be extended to monitor the safety conditions under the pit. It has broad application prospects in the fields of mines, subways and bridges[1].
