Hospital bed call systemAbstract:Generally speaking,the ward call system is a call system that facilitates flexiblecommunication between patients and medical staff,and is a means to solve information feedbackbetween medical staff and patients.The quality of the hospital bed call system is directly related to thelife safety of patients.For example,this year's new coronal pneumonia,it is really impossible to have aflexible and reliable medical system.The task of this subject is to design a sickbed calling system based on STM32 microcontroller anda control system to control its various functions.The system design includes matrix keyboard andLCD12864 LCD display circuit.In this design,each ward has a key.When the patient needs to press thekey,the display screen in the duty room can display the patient's bed number.When multiple people useit,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 informationtransmission.The staff on duty can display the information of the hospital bed from the LCD12864display,and the nurse station can quickly grasp the information.The software is programmed with Clanguage and modular design idea is adopted.The hardware circuit of the system is simple,and thesubprogram is universal,which fully meets the design requirements.Keywords:STM32,hospital call system,zigbee,LCD12864
