By comparing and analyzing the sample data of patients’ temperature,blood pressure,oxygen saturation and pulse rate,the method of collecting human physiological parameters can be developed. The system designs the Cortex-M3 system circuit and the CC2530 wireless module circuit,and also selects the suitable chip and the sensor acquisition module for the hardware platform. On this basis,by analyzing the software and hardware platform,the design of hardware circuit system is performed. In a word,the STM32 platform completes the programs of physiological signal acquisition,system control,display,storage,wireless communication module and Bluetooth communication module. The CC2530 platform completes the program development of the acquisition nodes,ZigBee routing node and the coordinator node. The ZigBee protocol stack completes the ZigBee network and the whole design.
