[Abstract]:With the development of low-power wireless communication mode and the development of on-chip system, It has become possible to deploy a large number of tiny smart sensor nodes on the body to monitor all kinds of information about the human body. Wireless body-area networks (WSNs) are those sensor nodes that are implanted into the body or placed on the surface of the body. Collect important physical and non-physiological data, send these receipts to the system database wirelessly for data storage, processing, analysis, and take measures to diagnose the system when necessary. The working area of the body area network is the body, which has certain limitations. Many factors such as flexibility, practicability, expansibility and so on need to be taken into account in designing wireless body area network sensor nodes and convergence nodes. The system designed in this paper has the following characteristics:. First, low power consumption. Low-power Bluetooth technology is newly introduced by Bluetooth technology alliance. Compared with traditional Bluetooth technology, low-power Bluetooth technology replaces the original idle state with dormant state, and the broadcast channel becomes three. The power consumption of Bluetooth is greatly reduced. Second, the flexibility is strong. Many mobile phones begin to integrate low-power Bluetooth technology in the market, which can be well connected to the smart sensor, no need to be limited to a fixed situation, the enhancement of flexibility can promote the popularity of the body area network. Third, low cost. The CC2540 chip selected for the system is a real on-chip system, requiring very few peripherals to work properly, and a package of 2,500 chips costs only about $9. The main work of this paper is as follows:. First, three popular wireless communication technologies in the market are compared, and the low-power Bluetooth technology and 802.15.6 standard are compared in two aspects, and the conclusion that low-power Bluetooth is also suitable for LAN network is obtained theoretically. Secondly, in the aspect of hardware and software design, the circuit diagram of sensor nodes with different functions is made according to their instructions, and the program code for collecting data from sensor nodes is compiled. The system structure and workflow of the body area network are designed, and the workflow of communication between the convergent node and the host computer and smart phone is designed, and the source code is compiled. Thirdly, in the aspect of hardware implementation, the sensor data acquisition is realized, and the collected data is transmitted to the upper computer and smart phone. The feasibility and success of the system are verified by the actual results.
