无线病房呼叫系统设计与实现

摘要

为解决传统有线病房呼叫系统布线复杂、维修不便且明线不雅观等问题,设计了一种具有无线通信功能的病房呼叫系统。系统以单片机为核心,采用无线收发模块 NRF2401和语音模块YY01,实现了病患与医务人员之间信息传输与反馈的功能,同时可将呼叫信息存储在监控计算机上,以便于信息管理。结果表明,系统配置灵活、功能可扩展、价格低廉,具有良好的可操作性。%The author of this paper has designed a ward call system with wireless communication to solve the problems of the complexity,ugliness and inconvenient maintenance of open wiring of the traditional ward call systems.The new system,based on MCU,NRF2401 wireless transceiv-er module and YY01 voice module,can transmit information and feedback between patients and medical staff,and store call information in computers with easy information management.The results show that the system has the advantages of flexible configuration,extendible function, low price and easy operation.
