The Choice Of Personnel To Locating And Tracking System＆the Study Of Zigbee Wireless Network System

Presently ,the tracking and orientation technology of mining personnel remain a blank field at home and abroad, people play a main role in the traditional orientation system,which lacking the quantitative index,veracity, faraway from the need of modern production.At abroad, generally the message of the tracking and orientation to personnel in the pit transmit by leak cable through wireless way such as infrared to ground system, the computer on the ground can judge the location that the personnel in the pit locate by dealing with the data received. Nevertheless, Some collieries of countries such as U.S.A., Japan,etc. have already implemented the tracking and orientation technology of mining personnel in whole ore, but the cost of this way is very high.At present, the tracking and orientation technology of mining personnel in domestic, actually it is only a kind of attendance and records the system of the radio frequency (RFID), doing a little in the tracking and orientation, which method is at the mine entrance, or other some key passways of the pit, using the radio frequency (RFID) the method that is recorded and followed that personnel register to going into the well of method to read (pay by credit card). This kind of RFID radio frequency reads and writes the system, including SuperRFID, neither impletement the tracking and orientation of person nor timely report the concrete position of the personnel in the pit, moreover, are helpless to improving the monitoring system of the existing safe factor of production too, which only can be regarded as a registered implement of personnel. The total institute of scientific research of coal has developed the tracking apparatus to the disappearance personnel, which mainly orienting the seats of personnel after the accident, within a dozen. It′s still unable to orient personnel in the pit omni-directional. According to severe situation of colliery safety and production of Chinese, how to set up an accurate, convenient navigation systems of personnel of the pit, arose a great concerns of the domestic governments at all levels.Nowadays,the requirement of the safety in production of domestic colliery become higher and higher, hence ,seting up a reliable and practical system to track and orient for personnel of colliery, which is very important realistic meanings to improve the security production management of the colliery. In this thesis,we designed a kind of economic,applicable system to track and orient of personnel in the pit which...
