一种基于Lora无线局域网的智能型医用点滴监护系统设计与实现

针对采用ZigBee等传统无线技术的医用点滴监护系统存在数据传输距离有限、系统功耗高等诸多问题,设计了一款基于Lora技术的低功耗医用点滴监护系统.按照实现的功能不同可将整个点滴监护系统划分为3个部分,各个部分之间通过Lora无线网络实现数据交互.其中检测端的核心器件为红外光电传感器,其将获取的点滴速度和药液余量一方面...

Design and implementation of an intelligent medical drip monitoring system based on Lora wireless LAN

The traditional wireless monitoring system based on ZigBee has many problems, such as limited data transmission distance and high power consumption. A low-power medical monitoring system based on Lora technology is designed. According to the different functions, the whole monitoring system can be divided into three parts, each part realizes data interaction through Lora wireless network. The core device of the detection end is the infrared photoelectric sensor, which sends the acquired dropping speed and liquid medicine margin to the hand-held end through Lora wireless network on the one hand, and to the patient through voice broadcast and LCD display on the other hand, and the detection end is also responsible for receiving the patient information sent from the hand-held end and the rear end. The backstage end is responsible for monitoring patients and nurses in an all-round way. The experimental results show that the medical drip monitoring system designed in this paper has strong anti-interference ability, can realize data long-distance transmission, not only low power consumption, but also easy to network, and has a wide range of application prospects.
