A Monitoring System Research Of Coal Miner Personnel Positioning Based On RFID

As coal mined accidents occurs frequently, the requirement for security of coal mine's producing is more and more rigorous. However, Coal mine exist the personnel management difficult. The people on the ground can't communicate with the people underground in time, and it's hard for them to hold the distributing and work information dynamically. Once the accident happens, the efficiency of rushing to deal with an emergency and relieving sick or injured person is low, and the rescue effect is not good. So a monitoring system for coal miner security is needed. For the coal mine situation,the thesis present coal miner personnel positioning based on RFIDThis thesis based on RFID, depending on MSP430 MCU system and ARM microcontroller, designs identification card and the long-distance read in 2.4GHz.The discussion covers:According to the feature of wireless communication in the pit and contrasts the schemes of traditional localization. The thesis present RFID, It adopt ALOHA algorithm for Anti-collision and design antenna. After the paper chooses the chips of the system ( MSP430 MCU and S3C2440A). That is MSP430 MCU system that controls sending of identification card and ARM microcontroller controls receiver of read for frequency.The third chapter and the fourth chapter propose designing ideas of identification card and read, software and hardware are designed for identification card based on the MSP430 MCU system, and for read based on the ARM9, reader's software platform is based on miscrosoft company's embedded operating system--Windows CE.net, and adopt embedded visual c++4.0 software. Achieve Program design and debugging and design intelligent control form.Finally the paper designes host computer of personnel positioning system. system development tools use Visual Basic 6.0 to develop the set of data collection and information processing of the Integrated Management System. Background use SQL Server 2005 database data.Test the total RFID system.after all the software has finished. All the data meets the national standard requirement and the result show that the design is reasonable and achieve its purpose。...
