Mine Search System Research And Design For Help

Serious coal mine accidents, the mine rescue personnel is a very important work, the study found mine / SOS system to improve mine rescue personnel decrease the rate of loss has an important role in the accident.Based on the search for help mine needs analysis, design of the search and rescue, crying for help and the gas content of the ambient temperature and test functions. And applying radio frequency identification (RFID) technology in accordance with the essential safety requirements designed by the MCU and CC1100 modules ATMEL89 posed by search and rescue, for help circuit, as well as by the temperature sensor and gas sensor TGS2611 DS18B20 composed of sensor circuit; prepared the system software, and studied the anti-collision RFID technology, using anti-collision technology applied to the binary system. Introduced the wireless transceiver chip circuit and system components, analysis of system power source, low-power design circuit design, electromagnetic compatibility in accordance with mine and anti-electromagnetic interference technology to map out the circuit board requirements, and installation.The results show that: The system can search and call for help function, search and rescue devices in the work process can effectively prevent the collision, and can signal for help on the display of information; systems in open conditions, the role of distance is more than 100 meters, the surrounding ambient temperature can be displayed correctly; and software settings on the gas content of more than timely warning. Meet system design requirements.
