本文设计的病床呼叫系统的核心采用的单片机型号是AT89C51系列,组成模块中包括了数字电路、显示电路以及矩阵键盘等,目的是完成医生护士与病人间传达信息。针对病房系统中设置了一个按键,只要患者按下按键,这个时候患者床位号就会显示在值班室的显示屏中,当很多人同时使用的时候能够完成循环显示,当医护人员要取消呼叫的时候,可以按下“响应”键。这个系统实现的是快捷系统,优点是效率高、成本低、安装方便,同时易操作。
In this paper, the design of the core of the call system using the microcontroller model is AT89C51 series, composed of modules include digital circuits, display circuits and matrix keyboard, the purpose is to complete the communication between doctors and nurses and patients. For the ward system, a button is set, as long as the patient presses the button, the patient bed number will be displayed on the display screen of the duty room at this time. When many people use it simultaneously, the cycle display can be completed. When the medical staff wants to cancel the call When, you can press the “response” button. The system is a fast system, the advantages of high efficiency, low cost, easy installation, easy to operate at the same time.
