A Research On The Safety Monitoring And Controlling System Of Mine Explosion-proof Diesel Vehicle

The application of explosion-proof diesel in the coal mine is more and more widely hasbeen an important subsidiary transport tool. But due to the mashgas, coal dust and otherflammable and explosive substances will be accumulated in coal mine, has danger ofexplosion, so the diesel vehicle must be explosion-proof processed and install a safetymonitoring system. Safety monitoring and controlling system not only guarantee the safeoperation of underground diesel vehicle, but also indirectly improve the efficiency of coaltransportation. This thesis mainly in the aspect of explosion-proof diesel safety monitoringsystem design to complete the following work:Analysis the factors of danger when the explosion-proof diesel vehicle work in coal mine,then put forward the design scheme; conduct the integral design scheme of safety monitoringand controlling system, acquires the physical parameters information of the explosion-proofdiesel vehicle through the speed sensor, engine surface temperature sensors, exhaust gastemperature sensor, engine oil pressure sensor, mashgas concentration sensor and then displayonline via the display module. If the parameters exceed the standard, then drive the soundand light alarm module, the lower computer achieve the function to speed down or stop themachine; Complete hardware the selection and the circuit design of each module, includingthe control core processor PCM-3370and data acquisition card PCM3718HO, the selectionand circuit design of temperature, pressure, mashgas concentration, speed sensor module,display and alarm module, executable module and so on; Complete preparation of thecorresponding program. Mainly include the sensor reading and writing program, ADconversion program, data processing program, real-time display program, sound and lightalarm procedure, control execution program; do the function test under the condition ofsimulating system. The simulation experiment results show that the safety monitoring system can realizediesel physical parameter monitoring, data display, alarm and control of the response function,the design scheme is feasible...
