Strengthening the daily monitoring of health sign parameters can effectively avoid the occurrence of diseases and accidents. Some current daily monitoring devices are large, inconvenient to operate, and single-functional, which do not meet people's needs for portable daily wearable multi-health parameter monitoring. In response to the above situation, this paper researches and designs a wearable multi-health parameter monitoring system based on Internet of Things technology in combination with telemedicine monitoring technology. The hardware module of this system contains seven parts, including MCU microprocessor, acceleration sensor module, temperature collection module, heart rate and blood oxygen collection module, respiration detection module, Bluetooth module and network communication data transmission module. This system can realize the monitoring of several health parameters such as body temperature, step count, travel distance, heart rate, blood oxygen and respiration. The overall structure adopts miniaturized design, which is easy to be embedded into more portable products. The system is designed with a supporting cell phone APP, through which users can view the measurement results of health parameters and real-time monitoring of dynamic information, which greatly realizes the management of their own health records. In addition to self-monitoring, it can also be transmitted to doctors or medical institutions through the network, which can realize remote monitoring or diagnosis. The experimental results show that the monitoring system is fully functional, small in size and has many measurement parameters. The accuracy of body temperature is 0.1 degree, the error of pedometry is 5%, the respiratory range is ± 346pa, the error of heart rate can reach ±2%+1 times/min, and the error of blood oxygen can reach ±2% in the range of 70-100, which can conveniently meet the needs of people's home daily multi-health parameters monitoring and telemedicine.
