Abstract


With the rapid development of China’s coal industry, mine safety has become an important topic can not be ignored. Existing antiquated mine safety monitoring system can not meet the needs of mine safety. In recent years, coal mine accidents, if they can set the device to accurately grasp the actual underground mine staff position, and the corresponding environmental parameters, carried out for the ground to secure the timely and effective rescue valuable time and reliable data, to the greatest to minimize casualties. In order to ensure the safe operation of the mine, should establish an early warning of dangerous rapid positioning system. This paper from the mine safety, this paper proposes the application of ZigBee wireless technology to mine personnel positioning system design. The system has information on the location of miners and number recognition and real-time tracking security warning feature. Which can guarantee the safe and efficient underground operations. ZigBee technology is characterized by: low power consumption, low cost, low transmission rate, short-range communications security and reliability, especially for mine safety operations personnel, positioning and monitoring.This in-depth study of the ZigBee network technology and IEEE802.15.4 agreement, the focus of ZigBee short-range wireless transmission technology, communication technology and other features and a detailed comparison of ZigBee wireless communication technology described the feasibility and advantages. Positioning system to track the use of domestic and international development and positioning technology, the latest research, designed to RSSI-based location technology to track underground personnel positioning system overall program. System uses the ZigBee wireless network with a combination of fiber-optic bus to build data communications platform, will face a number of underground personnel location data and other information transmitted to the control room Inoue’s data processing platform. Paper details the main equipment of the system, focusing on analysis of the hardware circuit design, including the CC2430 ZigBee modules based positioning sub-stations, base locator, mobile positioning terminals and optical transmission interface circuit design. ZigBee network application development based on TI’s zigBee stack Z-stack, this article describes the function of Z-stack-based device software design. Explosion-proof requirements for underground equipment, this system introduces intrinsically safe explosion-proof technology, the nature of security system equipment proposed design method. Finally, the article describes the network of ZigBee modules and testing methods.ZigBee-based underground personnel positioning system for its high reliability, high accuracy, easy to install and easy to extend the advantages of intelligence in the mine production will play an important role.
