Software Design And Realization Of Monitoring System For Mine Ventilator Based On Industry

Coal enterprise occupies a more important economic status in our country, coalmine safety requirements better than a year a year, and coal mining enterprises forsaving energy and reducing consumption, life security, gradually increasingrequirements. Ventilator in coal mine safety production play a decisive role, not onlyimprove the coal mine ventilator monitoring system software of saving energy andreducing consumption, improve the degree of coal mine mechanization, and savemanpower material resources, improve safety, have important significance.Mine ventilation system monitoring software are mainly computer monitoring,data filtering analysis, the final signal feedback analysis issue instructions of three parts.Mainly through to the underground air volume, temperature, wind speed, operation ofthe fan and so on carries on the on-line monitoring, real-time feedback data to the host.This paper from the principle of measurement of the parameters of mine ventilatorand the conversion formula derivation of various parameters, can be agents and reduce alot of unnecessary parameter measurement. Through the analysis of the characteristicsof the sensor, choose the appropriate sensor, reduce the measurement error in theprocess of the sensor to the system parameters. According to the working principle offrequency converter. And characteristics to choose the appropriate high-voltagefrequency converter, improve the operation efficiency of the fan. Hardware choosingSiemens S7-300and CHH100inverter, form the system communication networkthrough CAN bus way, CAN be real-time observed fan operation. Upper softwaresystem using MCGS configuration software, realizes the online monitoring of the fan,all kinds of data upload translates into icon form reflected on a big screen, convenientfan examiner for the operation of the mine ventilation and the parameters to make theright analysis. With mu C/OS-II programmable software, fan the various dataacquisition and realize the alarm function.Combined with the topic of the requirements of industrial field, the configurationmonitoring software design of the system, built the frame of software, the functiondesign of graphic interface, real-time database system, trend chart and report designmodule. The real-time database system is the emphases and difficulty in the wholesoftware design. The whole system man-machine dialogue to facilitate simple, flexible system, has good versatility and popularization. Finally, processing and display the dataof the experiment results.
