Development of engineering structure intelligent monitoring system based on LoRa

According to the real-time and accurate monitoring requirements of the engineering structure, an intelligent monitoring system based on Lora is developed. The system constructs the underlying wireless monitoring network through Lora communication technology. The wireless monitoring node realizes the plug and play of sensitive sensing elements and weak signal detection through WTIM (Wireless Transducer Interface Module, WTIM) module and NCAP (Network Capable Application Processor, NCAP) module. Based on Lora sensing network, the multi sensor cooperative monitoring is realized by the collaborative cognitive order parameter network model; the network intelligent monitoring system platform is developed by using JSP and SQL Server2016 relational database based on the C/S model. The experimental results show that the strain detection error can reach 0.1%, vibration detection error is 5%, and the intelligent network monitoring is realized.
