Mine Personnel Positioning System Application

At present, China's coal production industry is still in mine accident-prone, low level of safety, particularly the small township coal mines and private coal mines, backward because of security equipment, security awareness is not strong, not to establish a comprehensive safety management system, the situation is more worrisome. Therefore, the development of a set of suitable conditions, for medium and small coal mine production safety needs of staff orientation and management system has become a hot coal industry, one of the issues of common concern.Paper on RFID (Radio Frequency Identification) technology works, conflict prevention strategy and positioning system in mine workers in-depth studies and reliable applications. Main tasks are:1. according to underground coal mine environment and characteristics of RFID technology was designed based on RFID and CAN bus technology personnel mine shaft positioning system of the overall program.2. Complete system hardware design, including personnel tracking radio frequency card, card reader, repeaters, the total controller and handheld terminals. Each staff and key equipment are equipped with a wireless card, positioning the region face in every certain distance, RFID reader installed. Identity card to send on behalf of the wireless RF signals, the reader receives the RF signal after the signal sent to the appropriate identity relay, relay signals to electrical signals into light, and total controller through the fiber optic connection The total controller receives the optical signal into a serial communication signal to the data server.3. The completion of the system software design, main control node hardware, software, electronic tags to monitor the node software design.4. analysis and design based on RFID in Pingdingshan Coal Group mine in the coal mine workers eight positioning system.Papers on the system architecture, design diagram, hardware and software, etc. Principles of detailed description.
