摘要
针对目前人工监测输液治疗存在的问题,提出了一种基于光电检测技术、嵌入式无线通信与网络技术的无线智能监测系统的设计方案。系统选用无线单片机nRF9E5,由中央监测设备和无线智能监测终端组成分布式无线监测网络,实现了对点滴速度的实时监测与异常情况的自动报警。通过构建合理的通信协议,实现了新增终端的自动识别,确保了中央监测设备对多终端的可靠通信。
For solving the problem with the infusion process monitored by nurses, a wireless intelligent monitoring system of liquid dropping in the therapy is designed, which is based on photoelectricity inspect technology, embedded wireless-communication and network technology. As a distributed wireless monitoring network, the system, which uses wireless single chip nRF9E5, is composed of a center monitor and many wireless intelligent monitoring terminals. It isn＇t only able to monitor and display dripping speed timely, but also gives an alarm in case of abnormality during the process of transfusion. And, a reasonable protocol is designed in the system, which can identify new terminal automatically and assure the reliability of communication between center monitor and terminals.
