The Design Of Patients Management System Based On RFID

This paper introduces a design of patients management system based on RFID technology and proposes a new kind of compound double frequency electronic wrist strap design, of which internal packaging a microwave active tag (2.45GHz, the effective distance of70m) based on nRF2401RF chip and MSP430SCM, and a passive adhesive material tag, which just like paper, working at high frequency (13.56MHz, effective distance10cm, and it’s card reader is based on MFRC500RF chip and STC89C52SCM). This compound double frequency electronic wrist strap combines the advantages of active and passive RFID products, and makes itself have the ability of remote position and close recognition simultaneously, so that it can realize the patient’s remote monitoring and information management.This paper is divided into five parts. The first part is the introduction, introduces the project significance, the overseas and domestic research status and the integral design scheme of this system; The second part is the design of tracking position system at microwave, includes the reader and tag’s selection of each module chip and the design of hardware circuit, antennas, communication mode, programming, etc.; The third part is the design of entrance guard system at high frequency, in this part, it will introduce non-contact IC card Mifare1IC S50and ISO14443standard first, and then put forward the selection of each module chip and hardware circuit design of the entrance guard system, as well as the design of antennas, anti-collision mechanism, antenna tuning, etc.; The fourth part is the realization of upper computer to the patients management system, includes the database establishment and the visual interface design; The fifth part is the summary and prospect to the whole project.
