In this thesis, according the present situation and development trend of the instrument equipment management system, bining the basic theory of wireless sensor works, we propose a design scheme of the instrument and equipment management system which is based on ZigBee technology. After the careful analyse and study of the ZigBee wireless sensor work, we put forward a solution to the problems of the instrument equipment management system. Using means of ZigBee technology, and the wireless sending module,the data which is detected by detection module would sent to the receiving data will be transmitted to a puter through USB the management people of laboratory instruments and equipment will have an instant， convenient and efficient management. Thinking of factors about low cost, low power consumption and high performance in the design of hardware circuit,the sensor signal processing circuit, the power conversion circuit and interface circuit is based on the CC2430 also made a theory analysis on the design of antenna. In the software design, we mainly discusse the structure of the ZigBee protocol, and the functions of different nodes. A summary of full text has carried on in the end, and points out the deficiency of the design,the needed improvement and direction and focus of the future research .
