Research on the Application of Lora Mesh Technology in the Field of Service Performance Monitoring for Highway Infrastructure

With the development of sensors and communication technology, the service performance monitoring system of highway traffic infrastructure based on intelligent sensors has been widely used. By arranging sensors to obtain information such as strain, load, displacement and deformation of highway infrastructure, we can timely grasp its structural changes and health status, which is of great significance for improving the maintenance level of highway infrastructure. However, the current monitoring system mainly uses wired sensor network, which has a series of problems such as complex wiring, high cost and poor scalability. Therefore, in this paper, a highway traffic infrastructure service performance monitoring system based on wireless communication technology is designed by integrating LoRa and Mesh AD hoc networking technology. The system has AD hoc networking, multi-hop transmission, network self-healing and other functions. The experimental results show that the LoRa Mesh monitoring system using multi-hop transmission has obvious advantages in coverage and communication reliability, and has broad application prospects in the field of highway traffic infrastructure performance monitoring.
