基于51单片机的病房呼叫系统设计和实施

Based on the provided information, the research aims to design a ward call system using the AT89S51 microcontroller. The system includes a buzzer, digital display, indicator lights, buttons, and the microcontroller itself. When a patient in the ward requires assistance, they can press the call button which will notify the staff in the duty room. The corresponding room and bed numbers will be displayed on a monitor, allowing the staff to address the patient's needs. In the case of multiple button presses simultaneously, the system will prioritize based on the severity of each patient's condition, ensuring that urgent cases are attended to first. In terms of connectivity, the system utilizes a wired setup. This choice offers advantages in terms of security and reliability, as it does not interfere with the operation of other medical electronic devices. However, installing and maintaining the system can be cumbersome, and the responsiveness may not be optimal. In conclusion, this research project focuses on designing a ward call system using the AT89S51 microcontroller. The system aims to improve communication between medical staff and patients, enhancing the level and quality of service in hospitals. By incorporating a buzzer, digital display, indicator lights, and buttons, the system enables patients to easily request assistance. The duty room staff can receive these requests through a monitor, displaying the corresponding room and bed numbers. By prioritizing urgent cases, the system ensures efficient allocation of resources. Although the chosen wired setup provides security and reliability, it may pose challenges in terms of installation, maintenance, and responsiveness.
