The Coal Mine Trackless Tyred Vehicle Safety Monitoring System Design

Along with the coal mine automation production increased,the coal mine transportation in coal mining in the production of more and more importance.The convenience of mine transportation to a certain extent also affects the production efficiency of coal mine.Furthermore there are more harmful gases in coal mines,when the gas concentration exceeds the standard,it exists the possibility of explosionthe,so using the trackless rubber tyred vehicle transportation,can be convenient to monitor the coal mine of dangerous and harmful gas concentration,thus to avoid the coal mine unsafe events occur.But no trackless rubber tyred vehicle in running process,will also bring some harm to coal mine,so the design of a can not only solve the problem of external security monitoring to ensure its normal operation of the system is very necessary.The research on safety monitoring of trackless rubber tire vehicle problems.This topic in the design of coal mine operation risk factors were analysis at the same time,the safety factors of trackless rubber tyred vehicle to run their own analysis,clear the trackless rubber tyred locomotive in operation should be monitoring parameters and if the unsafe factors in the emergence of trackless rubber tyred vehicle will react.In the absence of trackless rubber tyred vehicle safety monitoring system hardware design,select the measurement of temperature,CO concentration,wheel speed ten parameters of ten kinds of sensors,and correspond to the design of the measuring circuit.The system uses the microcontroller using A/D conversion chip analog to digital conversion,data acquisition end after data processing will be displayed on the LCD12864 monitor.The software of the trackless tyred vehicle safety monitoring is designed.The preparation of the monitoring interface of the host computer is designed based on VB.When the vehicle speed or the oil pressure measuring parameter exceeds a set value,the microcontroller will notice sound and light alarm circuit or directly through the solenoidvalve to direct the trackless rubber tyred vehicle parking and working personnel to make processing and re run.In the simulation experiment of the test monitoring parameters are more close to the actual value,for the trackless rubber tyred vehicle monitoring system design.Experiments and tests show that design is reasonable and feasible.
