基于低压电力线的病房监护系统设计

Ward Monitoring System Based on Power Line Communication

目的:介绍一种基于低压电力线通信的病房监护系统。方法:电力线通信优点多多,本文把电力线通信用到病房监护系统中,利用电力线载波通信技术、单片机多机通信和计算机监控管理技术,设计出一种基于低压电力线通信的主从结构的病房监护系统。结果:经试验室检测该系统能够实现正确的通信功能,最大通讯距离为300m,能够满足一般医院的要求。结论:此系统不需要布线,即插即用,可远程监控病人的体温、脉搏和血压等生理数据,并对非正常数据做出报警指示,极大地减少了护士的工作量,具有广阔的应用前景。

Purpose： Ward Monitoring System based on Power Line Communication. Methods：A Ward Monitoring System based on PLC is introduced in this paper. We mainly talk about the hardware design and software design of the system. The system adopt principal and subordinate structure, transmit data on low-voltage power line. Result： The system can communicate correctly in testing, and the max communication distance is 300 m. Conclusion： The system has many functions such as priority setting, records storage, etc. Nurses can monitor the patients＇ life sign parameters through the system.
