【正文】 system which is based on the Zigbee technology. It requires four signs of health information detection of human body: temperature, pulse, blood pressure, ECG, processing the information through the STM32 microcontroller, transmitting the information to PC to achieve realtime display via Zigbee wireless. It consists of two parts of hardware and software. The first is the temperature detection, using probe type temperature sensor DS18B20 to detect, which adopts single bus mode. The course of programming for temperature detection is in strict accordance with the chip to read and write timing. The second is the pulse detection, using infrared pulse sensor to detect changes in the fingertip blood because of the heart beat. We calculate the pulse rate through signal amplification and adjustment circuit processing. Once again is the ECG testing, collecting the ECG signal by electrocardiogram, reading the voltage value through the AD converter, and sending the data to the PC to achieve realtime display of ECG data. Finally, the blood pressure measurement uses a modified automatic sphygmomanometer BK6022 to measure human blood pressure information. SCM also includes a power supply circuit, overrun sound and light alarm circuit, reset circuit, and PC applications. Research and development of this system is conducive to a better hospital medical care, transferring information between medical sensor and monitor, reducing connection between the monitoring equipment and medical sensor, making the guardian have more freedom of space, achieving better services for patients, and improving the work efficiency of hospital care, and it is fortable, low power consumption, scalability.
