| The ground coal storage bunker methane concentration wireless monitoring methods mostly use the traditional underground wireless monitoring system of methane concentration,cannot completely solve the problem of coal storage bunker methane overrun,causing potential safety problems,causing damage to property staff.Therefore,developed for the coal preparation plant storage bunker methane concentration wireless detection system exclusive become important technical problems.With the further development of the coal mine intelligent and wireless monitoring system in coal preparation plant storage bunker methane concentration development has good prospects.Thesis according to the coal storage bunker methane release characteristics,the methane sensor placed in storage bunker at the top and upper angle position.Through the hardware structures and software design,the development of the wireless monitoring system of methane concentration in coal preparation plant storage bunker,the suitable storage bunker in the ZigBee technology,the coordinator transmitted to the host computer for data display,storage and analysis and set system detecting and warning threshold,realize the wireless monitoring coal preparation plant storage bunker methane concentration.Paper to Shanxi Hot Stone coal mine coal preparation plant storage bunker as the test site,the practical application of the system,according to the measured field and minimum system relative error value of 0.005%,and the relative error fitted value is about 0.8655.Compared with manual collection,the work efficiency and accuracy can be significantly improved.System is stable,obstacle free copy mine methane monitoring system has many shortcomings,on the safe operation of the coal preparation plant production line has important significance. |
