| Nowadays, the technology of TOI (Things of Internet), which is one of the hotresearches, has entered a rapid period of development, and it is widely used in variousfields. As one of the key technologies of TOI, RFID technology has a very strongmomentum of development and research value for the development of computers, IC andnew business models, as if the RFID technology has developed for decades. The currentRFID technology has melted chip technology, integrated system software and modernbusiness models, and realized its value in the field of transportation, security, logistics,manufacturing, etc.In this paper, RFID system is design for the personnel location and tracking in theenclosed areas such as coal mine, workshops, etc. The RFID system includes4sections:tags, readers, locators and PC. This article introduces the RFID system from the systemframework to the hardware and software design, and can read data from the tag and writethe data to the tag. The RFID tag is also optimized.This design of the RFID reader system frequency is2.4GHz, compared to theoriginal RFID equipment in the laboratory, this data transmission of the RFID system ismore efficiency, and anti-collision of the RFID system is better. The tag can make alarmwhen its voltage is low than2.1V. The tag also has ultra power operating mode, whichcan longer the work time of the tag. The work time of the tag is2times longer than thelast tag in the lab, and its volume is reduced by50%than the last tag in the lab. The taghas achieved the miniaturization. |
