Design And Implementation Of A Wireless System For Unstable Rock Monitoring In Wulong County

In recent years,China's economy has entered a period of vigorous development,the negative impact of human activities on the natural environment are gradually deepened,geological disasters frequently been reported,becoming an important factor of affecting the national economy,and even result a serious threat to people's production activities and lives and property.These reported disaster illustrate the lack of work in geological disaster monitoring and prediction in China,can not form a unified disaster monitoring and prediction systems.With the development of network communication technology,new communication technologies continue to be applied to the monitoring of geological hazards,geological disaster monitoring system based on wireless communication has also been universal application.This paper use a certain large perilous rock in Wulong County as the research object,take the terrain of the large perilous rock as the basis,with the promote to prevent and control of geological disasters in Wulong County as the goal,combined with embedded technology,wireless sensor network technology and GPRS wireless transmission technology designed and implemented a set of field data collection,on-site wireless network,remote data transmission and other functions crag monitoring system which can provide real-time field data for the monitoring center to predict the perilous rock.Thesis mainly use RF433 communication protocol and GPRS / GSM technology to design the communication network system,use STM32F103 series chip to implement software and hardware,and ultimately complete the perilous rock monitoring system design and applicant in the field.The main content of this paper:(1) Design the system functional requirements base on the formation conditions of unstable rock disaster in Wulong County, select environmental parameters and sensor type of the site to be monitored;(2) Thesis design the overall scheme of system, including communications programs and acquisition program, complete chip selection and hardware design. Design the node acquisition program base on the classification of a sensor;(3) Design the collection software and transmission software base on the type of sensor nodes and communication protocol, achieve the field data collection, communications, networking and remote interactivity;(4) Describe the major equipment of system, measure the error of the node module, describe the system process of on-site installation, and complete communications debugging and functional site of the system implementation.Field application shows that the paper designed perilous rock monitoring system can collect sensor information in real time,preserve the field information data,achieve the perilous rock band remote monitoring,provide data support for prediction of perilous rock disasters in Wulong County.
