Abstract


The proposed system consists of coal mine safety base stations, base station controllers , control centers , and security information terminal. The system is capable of real-time dynamic monitoring of the concentration of methane and other harmful gases that can monitor the human defense Mine Road safety hazards that may exist . Underground cable network using CAN and Zigbee wireless hybrid network combining way through security information carried by the miners monitoring network extends to each terminal so that mining face , dynamic tracking. Control center through a friendly interface you can view the gas concentration, temperature , humidity, the latest data with historical data , you can view alarm history , and these data in graph form visual display. Base stations and base station controllers based LPC2119 ARM family of microprocessor core design , complete safety information terminal and control center communications between tasks. Base stations and safety information terminal using a technique based on Zigbee wireless transceiver module SZ05 series for embedded networking communication , using MC14LC5480 voice chip voice system features a built-in CAN controller based LPC2119 P82C250 supplemented by multi- base station transceiver between network connection . The base station controller through the CAN bus networking communication with the base station , the base station monitoring the working state , the base station and coordinate the transfer of information between the mobile terminal , the control center via RS232 PC for information exchange . In this hardware platform based on the LPC2119 microprocessor given based on the software design process , including initialization, wireless communication module communication protocol development and communication program design , voice-enabled software design and programming , base stations and base station controllers the communication protocol development and main design, system design and control center monitoring program PC-side man-machine interface design. After repeated testing, to achieve the control center PC, receive security information terminal detects the environmental parameter data and determine whether the concentration of the gas gauge , also achieved through man-machine interface to query data , view graphs and sending commands.
