Design Of Mine Wireless Sensor Module

Mine wireless sensor system is the combination of wireless sensor technology and engineering security technology. It not only solves the traditional wireless sensing transmission problems, but also solves the coal mine of the multi-path effect, communication conflicts, explosion-proof etc. It has a broad prospect in the underground stuff locating, underground information collection etc.The thesis analysis the data transfer process of wireless sensor network.Based on the characteristics of personnel locating, it develops a programme of personnel locating which is based on the combination of a single chip and RF chip technology. It designs a point-to-point data transmission system, through sending and receiving the data can judge the personnel location.In this thesis, overall design of the module has been completed.In sending module, realize the module's low-power solutions through the design work in different modes of single-chip,therefore it extends the life of the module.Using the A/D sampling features,sample the voltage real-time can ensure the stability of the module. RF chip works in the Shock Burst mode can ensure the reliability of data transmissions. In the receiving module, RS-485 technology is used to realize data transmission with PC. On this basis, the circuit design of hardware is implemented; the software for the transmission and reception of data is realized also TDMA technology is used to solve the communication problems of conflicts. It completes the data transmission between module and Inoue Monitoring Centre.After the software debugging, the module can be accurate to send and receive data through the serial debug.It can serve as the data transaction bridge between the host computer and the crew.The programme is verified to be feasible and achieves the objective.
