基于ZigBee协议的病房呼叫系统研制

Development of Ward Calling System Based on ZigBee Protocol

目的:研制一种基于无线传输协议的病员呼叫系统,避免以住系统布线复杂的缺点。方法:采用ZigBee协议,以呼叫控制台作为网络协调器,呼叫分机作为终端节点,并在每个房间配置路由器作为信号中导。结果:系统经过初始配置后,能够对病员呼叫进行报警,同时提示床位号和所在房间号,并具有完备的网络故障检测机制。结论:系统安装方便、智能高、可扩展性强,符合病员呼叫系统的发展趋势。

Objective To avoid complicated wiring, a ward calling system based on wireless protocol is studied. Methods The system adopted ZigBee protocol, composed of calling console as network coordinator, bed-extensions as terminals and network routers in each ward, Results After initial configuration, the system could ring an alarm and gave the patient＇s bed number and ward number when patients called. Also it provided the automated network faults detection system. Conclusion The system is characterized with convenient installation, high intelligence and easy expansibility, and accords with the trend of technology.
