Broken wires monitoring in Mingchuan Road Bridge

Brief:The Yangtze River Diversion project is a large-scale cross-basin water diversion project, which mainly focuses on the urban and rural water supply, the development of navigation along the Yangtze River, and the improvement of the ecological environment of Chaohu Lake and Huaihe River. With the encouragement of this policy, many suspension Bridges and cable-stayed Bridges have been built, and the safety monitoring of Bridges has become more important.


 Overview:

The Yangtze River Diversion project is a large-scale cross-basin water diversion project, which mainly focuses on the urban and rural water supply, the development of navigation along the Yangtze River, and the improvement of the ecological environment of Chaohu Lake and Huaihe River. With the encouragement of this policy, many suspension Bridges and cable-stayed Bridges have been built, and the safety monitoring of Bridges has become more important. As the traditional inspection method of bridge cable is regular inspection with inspection equipment, it is not only impossible to monitor bridge cable for a long time, but also needs a lot of time and professional quality inspection technicians every time. After the owner's selection, the RAEM1 monitoring system of Qingcheng Acoustic Emission Institute was identified as the monitoring product of the bridge.

 

 

Working principle:

RAEM1 acoustic emission monitoring system can accurately detect the break signal of the suspension cable, process and analyze the signal, and then upload the signal to Qingcheng Cloud platform through 4G communication, so that customers can see the status of the suspension cable in real time on the terminal equipment. The built-in algorithm of the cloud platform software can calculate the wire breaking rate of the suspension cable through the received cable breaking signals, and can trigger an alarm when the wire breaking rate reaches a preset value, and notify customers by sending SMS or email.

 



 

Composition of RAEM1 Acoustic emission monitoring system:

1. Bridge acoustic emission sensor: it is installed on the suspension cable of the bridge to collect the fracture signal, convert the signal into telecommunication and transmit the signal to the RAEM1 monitor after amplification.

2. RAEM1 monitor: Analyze signals from sensors and upload data to the cloud platform.

3. Qingcheng Cloud platform: real-time display of monitoring data, and provide calculation and alarm functions.

Results:

Different from the traditional regular inspection of bridge cables, RAEM1 acoustic emission monitoring system can not only carry out long-term unmanned monitoring of bridge cables, but also accurately record the position of wire breaking signal, breaking time, number of broken wires and even broken wire rate, and trigger the alarm to the customer's terminal equipment when the bridge is abnormal.
