Based On Rfid Indoor Personnel Tracking And Pharmaceutical Anti-counterfeiting And Management

RFID is a kind of auto-identify technique raised in the 1990's. And nowadays, it has been a hot topic to research and study the theory and application in this domain and also many enterprises have set foot in this industry. There are many reasons due to its advantages, such as large volume of data, confidentiality of high anti-jamming capability to identify short, lower cost. It is worthwhile trying to apply this technology to other industries, and helping them to improve operational efficiency and reduce operating costs.As everybody knows, China has a big problem of graying of population, which will be resulted in the difficulties of nursing and serving the old. Mean while, after the entry to WTO, with the descending the tariff of pharmacon imported, and the problem of false pharmacon, many pharmaceutical manufacturers are challenged and threatened.The paper takes the pharmaceutical industry as the background, trying to introduce RFID to the field, to help the development of China's pharmaceutical industry better.In the first place of this paper, a few of common automatic identification technologies are introduced, and following them comprehensive analysis and comparison are described respectively. Secondly, the composition, classification, characteristics, applications and Internet of things of the RFID system are specificly analyzed. Then the primary principles of RFID is studied, especially the analysis of anti-collision mechanism, a dynamic binary system based on the structure of RFID anti-collision search algorithm is proposed and achieved, and the results of simulation also illustrate that the new algorithm has better performance in comparison with the existing dynamic binary algorithm, and with the increase of the tags and the length of EPC, the advantages are more obvious. And then face to the hospital staff indoor positioning and tracking done in-depth studies, establish a system based on LANDMARC mathematical models and introduce Z direction vector as interference factors for simulating...
