摘要

随着科学技术的发展，无线技术在我们生活的不同领域都得到了十分普遍的应用，而医疗方面对无线技术的需求也是日益增加。病床呼叫是进行医患沟通从而传递临床信息的重要方式, 病人可通过病房呼叫系统将请求迅速传递到医生或护士处,同时会在监控中心主机上留下及时准确并且完整的记录, 病房呼叫系统是提高医院或养老院等设施的护理水平的必备设备之一。

本设计是以AT89C51单片机为核心，通过无线信号传输技术来进行信息传递从而构建出的无线呼叫系统。系统通过键盘进行信号输入，无线模块进行信号发送和接受，信号通过单片机处理进而发送到数码管显示模块和声音报警模块实现报警呼叫功能。本系统优点是通过单片机的优良性能大大降低了生产的成本，同时通过无线技术提高了应用范围，有着成本低、效率高、操作方便等特点。

ABSTRACT

With the development of science and technology, wireless technology ha s been widely used in different fields of our life, at the same time the dem and for wireless technology is also increasing.Clinical call for help is an im portant means to transfer the clinical information of the ward call system, th e patient's request can be quickly transmitted to the doctor or nurse on duty, and keep accurate and complete records in the duty room of the monitorin g center on the host, is one of the necessary equipment to improve the leve l of nursing and hospital ward.

The design is based on AT89C51 microcontroller as the core, through t he wireless signal transmission technology to transmit information to constru ct the wireless call system. The system of signal input through the keyboard module, wireless signal sending and receiving signals, and then sent to the digital tube display module and voice alarm module to achieve the alarm cal l function through the single-chip processing. This system has the advantages of excellent performance through the microcontroller can greatly reduce the production cost, at the same time through wireless technology to improve t he range of applications, has the advantages of low cost, high efficiency, co nvenient operation.
