【摘要】：现阶段,世界各国都在大力发展智能化设备和系统,尤其是无线技术应用,近几年来更是飞速发展。但对于病房呼叫系统,大部分地区医院都是采用传统的有线呼叫,很少地区甚至还是沿用最早的人工呼叫,这些呼叫方式费时又费力。而且传统病房呼叫系统存在着诸多弊端,如布线困难,排线困难,安装、维护不方便,也不便与临时增加床位呼叫器等。现在病人对医院要求是快速及时地诊断与治疗,减少与降低病人的就医时间与成本。随着各种无线的日趋成熟,也会催生出新的技术应用需求。特别是近几年,ZigBee技术的发展速度更快,应用更广泛。尤其在病房呼叫方面,ZigBee技术有着特别的优势。ZigBee是一种短距离无线通信技术,具有低功耗、高可靠性的数据传输,网络容量大、时间延迟小、兼容性强、安全性高、成本低、协议套件紧凑简单等一系列优点。因此,鉴于此技术的优点,本文依据ZigBee软、硬件技术设计了一种简单的无线病房呼叫系统[1]。本文根据实际需求设计的无线病房呼叫系统,区别了传统的有线呼叫系统。本文将由以下三大部分组成。第一部分：阐述了ZigBee的技术背景,ZigBee勺发展历程。分析了国内和国外无线系统所处的状态。同时,指出未来无线呼叫系统的一种发展态势。本文介绍了ZigBee技术的特点,与几种短距离无线通信技术作了比较,并介绍了ZigBee网络体系结构和网络拓扑结构。第二部分：分析了系统的实际需求,根据需求,对系统的结构作了一个大概的描述,确定无线系统的设计方案。利用ZigBee CC2530开发实验平台,对其中的接口模块进行分析,阐明某些接口模块通用的接口电路,给出部分接口电路图。然后分析ZigBee协议栈的功能、协调器组建网络的过程,使用其内部丰富的库函数,编写程序实现系统功能。第三部分：确认程序的完整性与正确性,烧录程序,模拟仿真设计的软件结构是否正确,确定系统组网结构的正确性。然后对其系统功能进行实验测试,确保系统正常通信使以达到预期结果。综上所述,本文实现了一种新的无线呼叫方式并应用在病房中。该系统具有操作简单、稳定性好、功耗低、安全性高易与安装调试的特点,能满足病人的基本呼叫需求。此种技术系统在生活中的应用前景始终被人们看好。
[Abstract]:At present, countries all over the world are vigorously developing intelligent equipment and systems, especially the application of wireless technology, especially in recent years. But for the ward call system, most hospitals use the traditional wired call, very few areas or even use the earliest manual call, these calls are time-consuming and laborious. There are many disadvantages in the traditional ward call system, such as difficult wiring, difficult wiring arrangement, inconvenient installation and maintenance, and temporary addition of bedspace pager, etc. Now patients are required to diagnose and treat quickly and in time to reduce the time and cost. With the growing maturity of various wireless, it will also give birth to new technology application needs. Especially in recent years, ZigBee technology is developing faster and more widely used. ZigBee is a short-range wireless communication technology with low power consumption, high reliability, large network capacity, low time delay, strong compatibility, high security and low cost. Protocol suite compact simple and so on a series of advantages. Therefore, in view of the advantages of this technology, this paper designs a simple wireless ward call system based on ZigBee software and hardware technology. In this paper, the wireless ward call system is designed according to the actual demand, and the traditional wired call system is distinguished. This article will consist of the following three parts. The first part: the technical background of ZigBee and the development of ZigBee. The state of wireless systems at home and abroad is analyzed. At the same time, it points out a development trend of wireless call system in the future. This paper introduces the characteristics of ZigBee technology, compares it with several short-range wireless communication technologies, and introduces ZigBee network architecture and network topology. The second part: the actual demand of the system is analyzed. According to the requirement, the structure of the system is described in a general way, and the design scheme of the wireless system is determined. Using ZigBee CC2530 to develop the experimental platform, the interface module is analyzed, the common interface circuit of some interface modules is clarified, and some interface circuit diagrams are given. Then, the function of ZigBee protocol stack is analyzed, and the process of constructing the network by the coordinator is analyzed. The rich library functions are used to realize the system function. The third part: confirm the integrity and correctness of the program, burn the program, simulate the design of the software structure is correct, determine the correctness of the system network structure. Then the function of the system is tested to ensure the normal communication of the system to achieve the desired results. To sum up, this paper implements a new wireless call mode and applies it to the ward. The system has the characteristics of simple operation, good stability, low power consumption, high safety, easy installation and debugging, and can meet the basic call needs of patients. The application prospect of this kind of technology system in life is always favored by people all the time.
