With the improvement of living standards,people pay more attention to their health. To meet this demand,the project focuses on the research of wireless location technology and wireless temperature acquisition in the hospital environment. The hardware platform of positioning system adopts CC2431 chip based on ZigBee technology,which operates in the 2. 4 GHz band,with low power consumption and low cost,and can realize a large area deployment. In addition,it contains hardware localization algorithm,combined with CC2430 chips the plane localization can be achieved in the scope of 64 m*64 m. After the test,the position error is less than 3 m. Ward tempera-ture acquisition system uses the CC2431 chip,temperature is accurately to bits,which can satisfy the needs of temperature of monitoring indoor and outdoor. The system can collect in real time two wards’ temperatures which are displayed on the PC software interface and stored in a MySQL database for other application calls.%随着生活水平的提升，人们对自身健康更加关注。为满足这一需求，本项目重点研究了在医院环境的无线定位技术和病房的无线温度采集。定位系统采用的硬件平台是基于ZigBee技术的CC2431芯片，它工作在2.4 GHz频段，具有低功耗、低成本的特点，能够实现大量部署。此外，它带有硬件定位算法，配合CC2430芯片能够实现在64 m*64 m范围内的平面定位。经过测试，其定位误差小于3 m。病房温度采集系统采用CC2431芯片，温度值精确到个位，可以满足监视室内及室外温度的需要。该系统能实时采集两个病房的温度在PC上位机软件实时显示，同时也保存到MySQL数据库中供其他应用调用。
