The Design Of Blood Pressure Monitor With Wireless Transceiver Function

With the concentration of the living environment and human being's concern about their health, per capita health care resources is becoming less and less. To solve this problem, scientists are constantly try a variety of ways to let the medical treatment become simple and convenient.This topic is based on the design of electronic blood pressure monitor wireless sensor network, the level of blood pressure response of the human heart and vascular function in health status. Blood pressure every day in time to prevent, identify problems, In recent years, high blood pressure in the elderly showed a trend of high. The traditional blood pressure measurement methods is not convenient. This requires small size, easy way to blood pressure. The subject system is designed to be used in community health point, just extended arm, press the button, electronic blood pressure monitor blood pressure will be measured by means of wireless transmission to the host node. and the host node will save the blood pressure data. People can view the data at any time in the future to know their blood pressure changes. So this need not have every household to buy a blood pressure monitor, this can reduce the cost.The system's main control chip is designed by Department of Electronic Science and Technology in Huazhong University of Science and Technology, this chip with Low cost, low power consumption and high security, Transceiver chip CC1000 was designed by Chipcon. ZigBee protocol meet the OSI architecture, IEEE802.15.4 defines the lower two layers, physical layer and MAC layer, ZigBee Alliance defines the application layer and network layer, ZigBee network formed by the two types of equipment, full-function devices (full function device), and reduced functionality devices (reduced function device), including three types of nodes, namely routers, coordinator, terminal equipment. Support star network, mesh network of three network tree structure, divided into beacon and two non-beacon mode, the topic is used in a star network. System was successfully collected blood pressure data, all the node formed a star network. So as there are blood pressure data transmit from RFD node, the FFD node will collect the data and save it.
