The Application Of Rfid Technology In The Detonator Product Safety Management

This article started from the current condition of our countries'detonator management. It studied the RFID technology and the feasibility of application RFID in the detonator management, and carried out the research of the terminal data acquisition system which based on RFID technology.This article analyzed the anti-radio performance of detonator at first, calculated the radio energy which picked up in the 915MHz radio field by the detonator and the least safety distance of detonator misfire on this condition. A conclusion has been drawn that the detonator whether or not misfire lies on the radio emission power of the RFID system,the length of the detonator's feet-thread and radio frequency. It took the digital detonator as the management object that has been developed recently, and brought forward the blue print of tagging the digital detonator and it's packaging box, what's more, the methods of encapsuling the tag to make it don't be affected by metal is researched by this article, as well as the security of tag's information during the course of wireless communication.By using of ARM7 microcontroller LPC2103 as the controlling core unit, it finished the hardware and software designing for the data collecting implement's motherboard. Then it successfully embedded the RFID read-write module and the GPRS wireless data transmitting unit. Program has been written and debugged for the data collecting implement, through serial communication port emluator to control the RFID read-write module realized the data collecting implement's read-write operation to the RFID tags, and using the GPRS unit finished the data collecting implement's communication function with the long-distance controlling mainframe. The first step has accomplished the thesis'research target.
