The Design Of The Mine Hydrological Monitoring System Based On STM32

Coal is one of the most important resources, as it guarantees the industrialmanufacture and the normal life of people in China. As China’s coal resourcesexploration deepening, mine area continues to expand and increase, themanagement of the coal mine has become increasingly difficult. In order to makecoal mining industry run smoothly, lives and property are the first of all the work.Water percolation and water leakage have resulted in a large number of accidentsin the process of coal mining, so mine hydrological monitoring is very important.Under the premise of ensuring the normal coal mining, designing a monitoringsystem can understand hydrologic information in real time and can be aneffective early warning, it can definitely improve safety problem.This article analyses the techniques of the mine hydrology monitoringsystem, combined with the actual situation of China’s coal industry, design RS485as core network to transmit date, transducer technique is front end to collectrelative information, Industrial Ethernet is terminal to upper computercorresponding in mine hydrology monitoring system. STM32microprocessorcore to establish a communication substation in each underground tunnel, it playsa transit role in the connection of preceding and following. Fieldbus network usesdifferent intelligent sensors to transmit the data information including water level,water pressure, water temperature, and flow to correspondence substation throughRS485. The communication substation transmits the data to Ethernet by RS485,the data transmit to the upper computer. It is convenient to send instructioninquires and set up pointed communication substations and sensors at any times,put all of hydrology data updated into servers. Meanwhile, it set sharedinformation on local area network.Establishing reliable water inrush model, reading the pertinent area ofhydrology data from upper computer, achieving water inrush model to calculate the possibility of water inrush in this area, the calculated number is called “waterinrush index”. Then collecting some threshold values by water inrush index thatdivides diggings into safety zone, possible water inrush zone, and danger zone,Simultaneously, comparing the divided result to the known condition that makethe hydrology monitoring system possess data collection, processing,transmission, and analysis, achieve the effects including timely warning andalarm.
