Research And Implementation Of Wireless Mine Pressure Monitoring System Based On WSN

In recent years, there are frequent accidents in China’s coal mine, especially mine pressureaccidents. It not only causes tremendous economic losses to our country and enterprises, but also be aserious threat to the lives of mine workers. With the use of WSN technology for mine pressuremonitoring, we can grasp the mine pressure information and reduce the risk of accidents, with no needof laying massive underground cable. So this technology has a high sense of academic research andindustrial applications. This paper designs the implementation of wireless mine pressure monitoringsystem based on WSN, and makes a thorough study on some technology.Firstly, this thesis does a design on software and hardware platform for data acquisition node andgateway node, including the selection of hardware components, schematic design, operating systemmigration and the building of a software development environment; Secondly, this thesis studies thewireless sensor network routing technology, analyzes the advantages and disadvantages of LEACH,then proposes an improved routing protocol LEACH-MMS with the need of mine environment, anddoes a comparison of energy analysis and simulation experiments; Next, a key technology-WSNtime synchronization used in mines is analyzed and studied, according to its dual needs ofhigh-precision and low-power, this theses improves the TPSN algorithm and presents anenergy-efficient WSN time synchronization algorithm EETS, and does some analysis and simulationexperiments to prove its feasibility; Finally, the function of wireless mine pressure monitoring systemis designed and implemented, including functional design of data acquisition nodes and gatewaynodes, format design of radio frequency data, creation of relational tables in database and theimplementation of human-computer interaction systems.
