Research And Design Of Wearable Monitoring System Based On Multi-sensor

With the rapid development of the Internet of Things technology, wisdom medical technology is affecting the daily life of ordinary people. At the same time, the development of sensor technology and the miniaturization of all kinds of chips make wearable health monitoring to be possible. Recently, how to design a long-term and thoughtful healthcare system for the ageing population and the urban professional crowd has become a problem which needs to be resolved in time. This paper studies a wearable monitoring system based on multi-sensor. The system consists of CC2530 module and sensor nodes. However, this healthcare system is controlled by upper-computer software.In this paper, the research work can be devided into four sections:After reading and referring to a vast amount of literature and paper, this paper puts forward an overall plan. Combining with present situation of wearable devices market, this paper has selected the key components of health monitoring system. In addition, Zigbee protocol was chosen to solve the wireless communication problem.In order to collect physiological signals from users, this paper uses heart rate sensor, body temperature sensor and brain wave sensor module to combine with CC2530 chips. By doing so, this paper has completed the collection of basic physiological and the design of sensing layer.Based on the analysis of the functions and demands required in wearable monitoring system, this paper sets up a Zigbee star network to transmit sensor data,meanwhile, Universal Asynchronous Receiver/Transmitter (UART) technology is used to transfer the data from the coordinator to upper machine. In this section, the transport layer of healthcare system was designed.Finally, this paper introduces the process of PC software design, which is regarded as the main task of wearable monitoring system application layer. When PC receives the data from coordinator, upper machine will do the following processing:on one hand, the data will be saved in database, so that users can analyze data anytime; on the other hand, data will be analyzed and processed, then the data and result will display via the PC software. If the software continuously captures the data that beyonds the normal range of monitoring value, the system will start the alarm in order to remind users to pay attention to their health.To ensure the reliability of the system, this paper has done a lot of tests, according to the results, the wearable monitoring system designed in this paper can provide long-term, real-time and accurate health monitoring.Certainly, the system can provide useful references to user,either.
