【摘要】 以短距离无线通信技术为支撑的短距离无线数据网络以其动态自组网、数据传输可靠、网络容量大等特点正被应用到广阔的应用领域。本文从梳理短距离无线通信技术的产生和发展入手,着重介绍短距离无线数据网络,并参考ZigBee通信协议标准,自己开发无线通信协议。该协议具备ZigBee自组织,低功耗等优点,克服了ZigBee通信芯片成本高昂,底层不开源的缺点,具备普适性,可以在当前主流微控制器上移植。本文在自开发无线通信协议的基础上进行无线数据网络技术应用研究。本文在分析病区无线智能监控系统应该具有的功能和组成构架的基础上,应用基于自开发无线通信协议的无线数据网络技术进行了系统原形的开发和制作。本文在整体把握无线数据网络技术,开发自有无线通信协议的基础上,解决了病区无线智能监控系统的关键技术问题。本文基于台湾宏晶科技公司的STC89C516RD+微控制器和Nordic公司的NRF24L01射频通信芯片完成病区无线智能监控系统的监测节点和网络协调器节点的硬件开发。本文自己设计一个无线通信协议构架,充分利用了NRF24L01自身特点,采用了轮询和跳频结合的通信方式。并在此通信协议基础上开发温度采集程序、无线数据传输程序、串口通信程序、显示报警程序,按键扫描程序,实现了基于该协议的软件开发。本文利用自己设计的节点和协调器软硬件平台,根据病区无线智能监控系统的功能和构架要求,实现了基于短距离无线数据网络技术和自开发通信协议标准的星形拓扑结构组网,完成了在节点和协调器之间有效可靠的双向数据传输。更多还原

【Abstract】 Short-range wireless data network with its dynamic ad hoc networks, data transmission reliability, network characteristics of large capacity is being applied to the wide fields of application.In this paper, sort out short-range wireless communication technology generation and development, begin to highlight short-range wireless data network, and refer to mature ZigBee communication protocol standards, develop our own wireless communication protocols. The purpose is based on self-development of wireless communication protocols for wireless data networking technology, applied research. Based on the analysis ward wireless intelligent monitoring system should have the function and composition of the framework, based on the application of wireless communication protocols based on self-development of the wireless data network technology of the system prototype development and production. In this paper, the overall grasp the wireless data network technologies, developing proprietary wireless communication protocol based on the solution of the ward Wireless Intelligent Monitoring System for key technical problems.Based on Taiwan’s macro Crystal Technology, Inc. STC89C516RD+ micro-controller and Nordic companies NRF24L01 RF communications chips to complete ward wireless intelligent monitoring system for monitoring node and the network coordinator node hardware development.In this paper, refer to ZigBee protocol standard, based on our own design of a wireless communication protocol architecture and protocol development based on the temperature acquisition program, wireless data transmission program, serial communication program, display alarm program, key scanner to achieve an agreement based on the software development. In this paper, the node of their own design and coordination of hardware and software platform device, according to Ward wireless intelligent monitoring system functions and architecture requirements, implementation based on short-range wireless data network technology and self-development of communication protocol standards for the star topology networking to complete the in the node and coordinator between the effective and reliable two-way data transmission.更多还原
