【摘要】：体温是指机体内部的温度，体温是机体发挥各项正常功能的重要条件，在日常保健、患者监护、临床诊断及大规模传染病预防和控制中也具有重要意义。体温值的准确诊断有利于了解身体健康状况、对病情做出正确判断，方便治疗工作的及时开展。目前绝大多数医院对临床患者体温的采集主要通过是人工定时测量的方式，由医护人员每天定点挨个病房通过传统水银体温计测量每个患者的体温值，手工记录和绘出患者体温变化曲线图，，以便于医生分析患者病情。此方式不但消耗大量的人力，而且不能实现大规模的测量，不能实时监测患者的体温变化，从而不能及时发现异常，可能使患者错过最佳治疗时机，同时频繁接触，对于传染性疾病，容易造成医护人员感染。为解决传统医疗监护中的上述缺点，本文致力于将近年来新兴的无线传感器网络技术应用到医疗行业，设计并实现了一种基于ZigBee技术的体温监测系统，根据该系统实际应用需要采用ZigBee树形结构网络，实现了对群体体温大规模、快速、准确的监测，及时发现患者体温异常现象。在本文所述系统的设计中，具体设计思路如下：硬件方面，以TI的SoC芯片CC2530为微处理器芯片，以IST公司推出的数字型集成传感器Tsic506为温度采集芯片，该芯片是单总线结构；软件方面，基于TI公司发布的半开源Z-Stack，采用IAREW为系统应用软件开发平台；数据拟合方面，选用七维高科有限公司独立开发的1stOpt数学优化分析综合工具软件包；无线通信协议方面，选用ZigBee无线网络通信协议；系统功能测试方面，用CC2531USB Dongle和Texas Instruments Packet Sniffer软件搭建成ZigBee协议分析仪，对网络功能进行测试。本系统在病房区布置ZigBee无线体温监测网络，通过腕带终端实现对佩戴人员体温的测量，体温相关数据的通信是通过ZigBee无线网络来完成的。腕带终端测量完的体温数据通过ZigBee网络由路由转发或直接发送到协调器节点，协调器再通过串口RS232与护士站的PC机通信，PC机通过串口接收、显示和处理数据，实现了一种基于ZigBee技术的体温实时监测系统，该系统可满足同时对多个体温信号进行实时监测，除此之外，便于携带、低功耗及扩展性强也是其优势所在。本文较详细地介绍了ZigBee无线通信技术的协议架构，通过与目前市面上流行的其他几种无线技术的对比，说明了ZigBee技术在本应用系统中的优势。详细说明了腕带终端的硬件部分和软件部分。文章阐述了整个系统的通信过程，并对测得的实验数据进行分析。该系统的应用能大规模、准确、快速地反映佩戴人员的体温状况，为人们日常健康保健提供依据，及时的发现异常的优点又能为患者争取到最佳治疗时机。同时可节约医院的人力、物力成本，减少医护人员的工作量，使其工作效率得到提高，且有效降低医护人员感染传染病的机率。
[Abstract]:Body temperature is the internal temperature of the body. Body temperature is an important condition for the body to perform all normal functions. It is also of great significance in daily health care, patient monitoring, clinical diagnosis and prevention and control of large-scale infectious diseases. The accurate diagnosis of body temperature is helpful to understand the state of health, to make correct judgment of the condition and to facilitate the timely development of treatment. At present, most hospitals collect the body temperature of clinical patients mainly by means of manual timing measurement. Each patient's body temperature is measured by the traditional mercury thermometer in the designated wards one by one of the medical staff every day. Manual recording and drawing of patient temperature curve to facilitate the doctor to analyze the patient's condition. This method not only consumes a lot of manpower, but also fails to achieve large-scale measurement, and can not monitor the temperature changes of the patients in real time, thus it can not detect anomalies in time, which may make the patients miss the best treatment opportunity and contact frequently at the same time. For infectious diseases, it is easy to cause health care workers to be infected. In order to solve the shortcomings of traditional medical monitoring, this paper applies the new wireless sensor network technology to the medical industry in recent years, and designs and implements a temperature monitoring system based on ZigBee technology. According to the practical application of the system, the ZigBee tree structure network is used to monitor the body temperature of the group quickly and accurately, and to detect the abnormal temperature of the patients in time. In the design of the system described in this paper, the specific design ideas are as follows: in hardware, the SoC chip CC2530 of TI is used as microprocessor chip, and the digital integrated sensor Tsic506 developed by IST is used as temperature acquisition chip, which is a single bus structure; In the software aspect, based on the semi-open source Z-Stackreleased by TI, IAREW is used as the system application software development platform, and in the aspect of data fitting, the 1stOpt mathematical optimization and analysis software package developed independently by Seven dimensional Hi-Tech Co., Ltd. is selected. In the aspect of wireless communication protocol, ZigBee wireless network communication protocol is selected, and the system function test is carried out by using CC2531USB Dongle and Texas Instruments Packet sniffer software to build ZigBee protocol analyzer. In this system, ZigBee wireless temperature monitoring network is arranged in the ward area, and the temperature measurement of the wearer is realized through the wrist band terminal. The communication of temperature related data is accomplished through the ZigBee wireless network. Through ZigBee network, the temperature data measured by the wrist band terminal are forwarded by route or sent directly to the coordinator node. The coordinator communicates with the PC computer of the nurse station through the serial port RS232, and receives the data through the serial port, displays and processes the data. A real-time temperature monitoring system based on ZigBee technology is implemented. The system can be used to monitor multiple temperature signals simultaneously. In addition, it is easy to carry, low power consumption and strong expansibility. In this paper, the protocol architecture of ZigBee wireless communication technology is introduced in detail, and the advantages of ZigBee technology in this application system are illustrated by comparing with other popular wireless technologies in the market. The hardware and software of wristband terminal are explained in detail. This paper describes the communication process of the whole system and analyzes the measured experimental data. The application of the system can reflect the body temperature of the wearer on a large scale, accurately and quickly, and provide the basis for the daily health care of people. The advantages of finding abnormal in time can also obtain the best treatment time for the patients. At the same time, it can save the cost of manpower and material resources, reduce the workload of medical and nursing staff, improve their working efficiency, and effectively reduce the probability of infectious diseases.
