【摘要】：系统的核心是at89c51单片机。还有其它辅助硬件电路,矩阵键盘、LED显示电路、蜂鸣器、数码管等。每个床位的病人要呼叫护士可以按自己床边的按键,此时值班室会有蜂鸣器响,相应的指示灯亮,并且在值班室的数码管上显示床位号。信号通过矩阵键盘进行输入,在用高级语言编写程序时,对键盘信号的获取非常重要。每个病房的病床旁都有一个呼叫按钮,当患者有需要医务人员帮助时,按下呼叫键,此时值班室的显示屏可显示此患者的床位号,多人按键时医护人员按下中断"响应"键取消当前呼叫,并且显示前一位按键呼叫着的病床号。
[Abstract]:The core of the system is at89c51 microcontroller. There are other auxiliary hardware circuits, matrix keyboard LED display circuit, buzzer, digital tube and so on. The patient in each bed can press the button on his bedside, and the buzzer will ring, the corresponding light will light, and the bed number will be displayed on the digital tube of the duty room. The signal is input through the matrix keyboard, and it is very important to obtain the keyboard signal when writing the program in the high-level language. There is a call button next to the sickbed of each ward. When the patient needs medical help, press the call button, and the display in the duty room can display the patient's bed number. The medical staff press the interrupt "response" button to cancel the current call and display the sickbed number called by the previous button when more than one button is pressed.
