Design And Research Of Slope Disaster Monitoring System Based On Internet Of Things

China’s terrain is complex,with frequent and severe geological disasters such as landslides,mudslides,and landslides.The construction of high-grade highways has developed rapidly,but the accompanying slope disasters are also increasing,posing huge risks to the safe operation of highways.Therefore,this article designs a slope disaster monitoring system based on Internet of Things technology,which evaluates slope safety and threshold alarms based on changes in slope angle of highway slope monitoring points,prevents disaster expansion,reduces casualties and property losses.The research has been conducted on key technical issues related to the timing collection,transmission,analysis,management,and alarm of data,and an integrated monitoring and alarm system has been proposed.The main work is as follows:1.Based on the JY901 sensor,the STM32F103C8T6 microcontroller is used to regularly collect the angle values of slope monitoring points and make threshold judgments on the changes in angle.After the monitoring equipment is laid,the angles of the X and Y axes are set to zero,and the safety threshold angle range is set to ± 3°.If the threshold range is exceeded,it is determined that a geological disaster may have occurred on the slope.The data is uploaded to the upper computer through the 4G module using TCP protocol for alarm.An anti-interference design was carried out for the circuit and PCB,and the data was filtered to achieve stable collection of angle data and battery voltage.2.The system uses a 7.4V lithium battery for power supply,and collects angle information from a set of monitoring points every ten minutes to determine the threshold.If it exceeds the threshold,it will be uploaded,and if it falls within the threshold range,the data will be stored.After collecting six times,that is,one hour,the battery level information will be measured and the 4G module will be activated to upload all the collected data.After the JY901 sensor,ADC voltage measurement circuit,and 4G module are collected and uploaded,they are turned off through software control.At this time,the STM32F103C8T6 microcontroller is in stop mode and waiting for the next alarm to wake up.3.Designed upper computer software to obtain data through sockets,perform real-time processing and analysis of the data,and determine the safety threshold for each group of uploaded angle data.If the threshold is exceeded,a disaster alarm will be issued.The data and analysis results will be displayed intuitively and clearly through a multi window design.Use log4 net to add a logging function to the project,saving the information uploaded from various points on the lower computer in text format for staff to view and analyze.The experimental results show that the monitoring equipment can operate stably and provide disaster alarms,and its functions and performance can meet the design requirements.The power supply battery used can ensure that the monitoring equipment can continue to operate for one year or more.
