单片机病房呼叫系统设计 摘要：一般来说，病房呼叫系统是方便于病人患者与医护人员灵活沟通的一种呼叫系统，是解决医护人员与病人患者之间信息反馈的一种手段。病床呼叫系统的好坏直接关系到病人患者的生命安危，像今年的新冠型肺炎，没有一个灵活可靠的医疗系统真的不行。 本课题的任务是设计出基于STM32单片机的病床呼叫系统以及对它的各项功能进行控制的控制系统。系统设计包括矩阵键盘，LCD12864液晶显示器显示电路，在该设计中每个病房都有一个按键，当患者有需要时，按下按键，此时值班室的显示屏可显示此患者的床位号，多人使用时可实现循环显示，医护人员按下“响应”键取消当前呼叫。值班室与病房终端利用zigbee无线通信技术进行信息传输。值班人员可以从LCD12864显示器显示病床的信息，护士站可以快速掌握消息。软件部分用C语言进行编程，采用模块化设计思想。该系统硬件电路简单，子程序具有通用性，完全符合设计要求。 关键词：STM32，病床呼叫系统，zigbee， LCD12864 Hospital bed call system Abstract: Generally speaking, the ward call system is a call system that facilitates flexible communication between patients and medical staff, and is a means to solve information feedback between medical staff and patients. The quality of the hospital bed call system is directly related to the life safety of patients. For example, this years new coronal pneumonia, it is really impossible to have a flexible and reliable medical system. The task of this subject is to design a sickbed calling system based on STM32 microcontroller and a control system to control its various functions. The system design includes matrix keyboard and LCD12864 LCD display circuit. In this design, each ward has a key. When the patient needs to press the key, the display screen in the duty room can display the patients bed number. When multiple people use it, it can realize circular display. The medical staff can press the response key to cancel the current call. The duty room and ward terminal use zigbee wireless communication technology for information transmission. The staff on duty can display the information of the hospital bed from the LCD12864 display, and the nurse station can quickly grasp the information. The software is programmed with C language and modular design idea is adopted. The hardware circuit of the system is simple, and the subprogram is universal, which fully meets the design requirements.
