基于32单片机的无线病床呼叫系统设计

Design of wireless sickbed call system based on32 single⁃chip microcomputer

设计了无线病床呼叫系统,以STM32单片机作为发射端的控制核心,采用Wi-Fi作为通信方式,用Android APP作为接收端的监控系统。在发送端通过4个按键来实现4个床位的模拟,当按键按下时,对应病床信号灯点亮,并通过ESP8266来实现无线信号的发射;当接收端接收到发射端发送的信号时,接收端APP中显示相应床位信息,并通过手机铃声来提醒医护人员,待医护人员反馈后,接收端病床信号灯灭,系统恢复初始状态。

The wireless hospital bed calling system designed in this paper uses STM32 MCU as the control core of the transmitter,Wi-Fi as the communication mode,and Android APP as the monitoring system of the receiving end.When the button is pressed,the signal light of the corresponding bed is lit,and the wireless signal is transmitted through ESP8266.When the receiving end point receives the signal sent by the transmitter,the receiving end APP displays the corresponding bed information,and reminds the medical staff through the mobile phone ring tone.After the feedback from the medical staff,the hospital bed light at the receiving end is off,and the system restores to its initial state.
