Abstract 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 TLWR841Nv8. 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.

Introduction Vast territory and diverse landforms have been widely recognized as the geological and geomorphic characteristics of China. This feature will surely lead to the occurrence of geological hazards and become a problem that cannot be ignored in China (Berariu et al. 2015). Some studies have pointed out that the causes of geological hazards are often complex and changeable, with such characteristics as gradual change, immediate change, multiple occurrences, and mass occurrence (Qin et al. 2018). At present, the condition of geological hazards in China is still very severe. In 2019 alone, a total of 6181 geological hazards occurred in China. As a result, 211 people were killed, 13 people were missing, and 75 people were injured, causing in a direct economic loss of RMB 2.77 This article is part of the Topical Collection on Geological Modeling and Geospatial Data Analysis * Jian Chen [email protected] 1

billion. In 2019, a total of 948 geological hazards were successfully predicted in China, involving 24,478 possible casualties and avoiding direct economic losses of RMB 830 million (the data comes from the 2019 official survey of the China Geological Survey) (Shen et al. 2019; Huo et al. 2020).
