摘要

随着医疗技术的不断发展和人们对医疗服务需求的提升，对于医院的管理和效率也提出了更高的要求。在医院的病房管理中，及时、有效的病人呼叫系统是提升医疗服务质量的关键环节之一。传统的有线呼叫系统存在着布线复杂、移动性差等问题，无法满足现代医疗服务的快速响应需求。因此，无线病房呼叫系统的研究与设计显得尤为重要。

本研究设计了一种基于单片机的无线病房呼叫系统。该系统以ST89C52芯片为核心，配以多种外围电路，如时钟电路、复位电路、键盘扫描电路、无线射频接受电路、无线射频发射电路、数码管显示电路和蜂鸣警报电路。通过Keil uVision4、Proteus ISIS和stc-isp烧录软件进行软件程序开发。该系统旨在提高医院病房的通讯效率，方便病人与医护人员之间的信息传递，为病患提供及时、有效的服务。无线通信技术在该系统中的应用，大大降低了布线的复杂性和成本，增强了系统的灵活性和可移动性。本设计的实施对于提升医疗服务的效率和质量具有重要意义。

Abstract

  With the continuous development of medical technology and the improvement of people's demand for medical services, higher requirements are also put forward for hospital management and efficiency. In the hospital ward management, timely and effective patient call system is one of the key links to improve the quality of medical service. Traditional wired call system has problems such as complex cabling and poor mobility, which cannot meet the rapid response needs of modern medical services. Therefore, the research and design of the wireless ward call system are particularly important.

The present study designed a SCM-based wireless ward calling system. The system takes ST89C52 chip as the core, with a variety of peripheral circuits, such as clock circuit, reset circuit, keyboard scanning circuit, radio frequency receiving circuit, radio frequency transmitting circuit, digital tube display circuit and beep alarm circuit. The software program was developed through Keil uVision4, Proteus ISIS and stc-isp burning software. The system aims to improve the communication efficiency of hospital wards, facilitate the information transmission between patients and medical staff, and provide timely and effective services for patients. The application of wireless communication technology in this system greatly reduces the complexity and cost of wiring, and enhances the flexibility and mobility of the system. The implementation of this design is of great significance for improving the efficiency and quality of medical services.
