| Owing to the particular environment in coal mine, charging the people in well is one big problem about the safe production and management in coal mine.In this paper, after a review conducted for present and development status for the mine monitoring system.Then present quention of people monitoring and solution for the tasks are stated in brief. This paper unified the present coal security situation in our country,designed a set ofpersonnel under mine region recognition system.A quite advanced RFIDtransmit recognize technique, is used to resolve wireless data acquisition followed up problem. Personnel information under mine is gathered to the survey station of identification. By power line with the interface home-made chip of SC1128 based on direct spread spectrum technique.Information is transmitted real timely to master control module in the transformer substation under mine. Information managermented unifiedly is delivered to the computer on the ground by RS485 bus. It is communicated personnel under mine and information system on the ground.Then it is realized personnel under mine regionrecognition.It can monitor real-timely personnel position under mine and therelated information.This system selects the method which wireless and wired unifies,it hasthe good extendibility.It may apply personnel management under mine in thelarge and middle scale coal mine. |
