Remote monitoring system based on Zigbee wireless sensor network

摘要

This paper deals with the monitoring system based on Zigbee wireless sensor network technique in details. The system adopts single-chipped microprocessor ZIC2410 radio frequency chip. By the upper computer software and programs of various physiological data acquisition, the physiological data of warded people, such as the pulse, blood pressure, blood oxygen saturation and electrocardiogram, are gathered by the PC software in real time, and then the collected data are transmitted to the remote medical monitoring center through the wireless sensor network. The data information of each node, including the location and health status of the warded people, can be displayed by the monitoring center software. It makes timely and effective medical guidance possible. The system is small-sized, low-power-dissipated and strongly compatible and can be connected to network with different hardware platforms. The author mainly introduces hardware circuit design of processor module, data acquisition module, and wireless communication module. The monitoring software of the host computer is developed by LabVIEW. Experiments prove that the system has good stability and security. It has very high practical value and promoting function in telemetrically monitoring field in the future.
