基于PLC的病房呼叫系统

Ward Calling System Based on PLC

针对传统病房呼叫系统结构复杂、施工难度大、扩展能力差等问题,设计了一款新型病房呼叫系统,该系统采用电力线进行数据传输。详细描述了电力线载波数据通信原理,依据系统实际功能需要对系统硬件电路和软件程序进行了设计,并设计了相关硬件电路进行实验测试。试验结果表明:所开发的基于PLC(Power Line Carrier)的病房呼叫系统具有电路设计简单、操作便利、组网容易等优点,能够满足医疗系统的各项技术要求。

Aiming at the problems of complex system traditional ward calling System, a new kind of Ward structure, great construction difficulty and poor scalability of Calling Power line. The principle of Power Line Carrier（PLC） Data hardware circuit and software program are designed according System is designed. The system transfers the data by Communication is described in detail, and the whole to the actual function requirements of the system, then a relevant hardware circuit is designed to conduct the experiment. The experiment results show that the Ward Calling System based on PLC designed has the advantages of simple circuit design, convenient operation and easy networking, and it can satisfy various technical requirements of medical system.
