Medical monitoring system based on ZigBee and network congestion control method

Abstract

The invention discloses a medical monitoring system based on ZigBee, and the system comprises a Zigbee wireless monitoring node, a ZigBee coordinator, a ZigBee-WiFi gateway module and a control host; the Zigbee wireless monitoring node sends human physiological data, environmental data, a detection alarm signal, a calling signal and an active alarm signal to the Zigbee coordinator; the ZigBee coordinator is used for collecting data obtained by the Zigbee wireless monitoring nodes and forwarding the data to the Zigbee-WiFi gateway module; the invention further discloses a medical monitoring network congestion control method based on ZigBee, and the medical monitoring network congestion control method based on ZigBee solves the problems that traditional equipment is difficult in wiring and not easy to move; the transmission data volume at the initial starting stage of the system is reduced, and network congestion is reduced. The congestion avoidance control is carried out to ensure the transmission of the most important data.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, more specifically relates to a ZigBee-based medical monitoring system, and also relates to a ZigBee-based medical monitoring network congestion control method, which is suitable for hospitals to monitor various physical indicators of patients. Background technique [0002] At present, most of the medical monitoring systems in our country are wired, but generally this kind of wired monitoring system is very complicated in the connection process, and most of them can only be placed in a fixed position for use, which leads to The efficiency of hospital medical monitoring equipment is greatly reduced during the use process, and the intricate wiring also increases the difficulty of maintenance of the equipment in the later stage. Facing the existing problems of the wired monitoring system, the research and development of a new, convenient Fast, safe and reliable wireless mobile medical ...
