Design and implementation of geological hazard monitoring system via the Internet of things

To realize geological hazard monitoring, a set of the Internet of things geological hazard monitoring system based on Mesh network combined sensor is constructed in this study. In this study, the Internet of things geological hazard monitoring system is divided into three parts according to its functions, which are acquisition system, wireless Mesh network system, and data monitoring platform. The hardware and software of these three parts are constructed respectively. Under the control of master control STM32, the acquisition system sends the data of temperature and humidity sensor and tilt angle sensor to the Mesh network through Lora module. Mesh network is developed and configured with OpenWrt under the hardware platform of TL-WR841Nv8. The data monitoring platform sets up a web server on the basis of Mesh network exit to realize a series of functions. Through the construction of three parts of hardware and software, the monitoring platform is established. Verified in three scenes of laboratory, campus, and lakeside, the function of the monitoring platform is realized. The Internet of things geological hazard monitoring system constructed in this study has achieved preliminary results, meeting the basic needs of the geological hazard monitoring system, which lays a foundation for the further optimization of the geological hazard monitoring system.
