Nursing monitoring system based on wireless sensor network

Abstract

The invention relates to a nursing monitoring system based on a wireless sensor network, which comprises a plurality of sensor nodes and a central node, wherein the sensor nodes are arranged at a contact point of a user and are used for collecting physiological parameters of the user, and each sensor node comprises a radio frequency module and an MCU (Microprogrammed Control Unit) power management module; the central node comprises a radio frequency module for receiving the physiological parameters collected by the sensor nodes, and transfers the physiological data to a PC (Personal Computer) terminal or an embedded device terminal through a serial port; and the sensor nodes and the central node are in point-to-point connection to form a start network topology structure. According to the invention, the start network topology structure is adopted, resources are concentrated, the network is easy to manage, the coverage area is concentrated, and the stability is strong; low energy consumption is realized between the sensor nodes and the central node through a CSMA / CA (Carrier Sense Multiple Access with Collision Avoidance) control protocol; and nursing personnel can conveniently know physical conditions of a patient in real time, and the aim of real-time monitoring the physical conditions of the patient is effectively achieved.

Description
