Research on Seismic Bracing Monitoring System Based on Wireless Transmission

Real-time data acquisition and monitoring of seismic bracings can help to maintain their effectiveness during service life and to improve the seismic resistance and disaster mitigation effects when strong earthquakes occur. In order to monitor real-time states of the seismic bracing, an intelligent monitoring system based on wireless transmission technology was designed. The system used CC2530 Zigbee module to establish a ZigBee wireless LAN, and combined MEMS vibration sensors and strain gauges. Meanwhile, the system used ESP32 to upload the measurement data to OneNET cloud platform through MQTT wireless communication protocol. The function of data visualization was designed so as to realize real-time monitoring of seismic bracing states. The experimental results showed that the proposed wireless monitoring system can reliably execute real-time data collection, storage, display, and hazard warning to guarantee the effectiveness of seismic bracings.
