Intelligent Mine Monitoring System Based On PIC MCU

The security problem of coal mines has been a focus that all the society is looking for it now. It has been an important problem relating to the property and life of people even influencing building harmonious society. So the research on the Monitor and Control System of Gas with high quality, high capability, high reliability and low cost will help to resolve this important problem deeply. The Monitor and Control System of Gas can continuously monitor gas concentration and control gas deflation. It also change the actuality that gas deflation and facilities of gas storage are overwatched by labor in our country.We bring forward a whole design scheme of the Monitor and Control System of Gas according to demand of user and the criterion of safety manufacture of china. This digital integrated design scheme includes collection , analyse and treatment of data function, control function and data communication function. This scheme can meet demand of user efficiencily and reliably.The Monitor and Control System of Gas can be divided into two main part, the intelligent gas sensor and monitor and control unit. The intelligent gas sensor can satisfy the user demand of high precision, high reliability, multi function and low power demand. The monitor and control unit can gather, process, and transmit the data of gas. The main computer at up ground also control the system for increase reliability. The monitor and control unit can also show the data by LCD.Either the intelligent gas sensor or monitor and control unit use MCU of PIC as core. The excellences of PIC MCU are fewer pin, multi function, driving LED directly, and lower power demand. The components around it are simple,so it can improve the reliability of the system.This paper discusses the design of hardware and software of the system in detail.Several parts of this system have been used by our customer for several onths. All of them are operating normally and full satisfaction and high praise of customers.
