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.
