【摘要】 在现代医疗中,血液及其制品是抢救患者生命的特殊药品。为了确保患者临床用血的安全性,就一定要严格储存和运输医用血液及其制品。因此,通过对血液冷链的实时监测,可以保证血液及其制品的质量安全可靠。本课题所研制的冷链监测系统对血液冷链的管理具有重要意义。本文通过对冷链监测系统的国内外研究现状进行对比和分析,提出了基于Zig Bee和GPRS的冷链监测系统方案。该系统主要由采集节点和主控节点构成。系统通过各个采集节点来获取被监测对象的温度等数据,并利用Zig Bee方式将数据都汇集到主控节点。主控节点将数据存储到本地的SD卡中以作备份,同时通过GPRS网络把收集到的温度等数据传递到远程监控中心。本文详细阐述了冷链监测系统的硬件实现过程。首先,对主要器件进行选型,Zig Bee芯片选用了TI公司的CC2530,主控节点的处理器芯片为ST公司的STM32F107RC。其次,详细描述了采集节点、主控节点和大功率路由节点的电路设计。监测系统的软件设计主要包括硬件底层驱动程序的设计和远程监控软件的设计。硬件驱动主要包括GPS定位、GPRS数据传输、USB、SD卡、以太网、串口和Zi Bee驱动等。远程监控软件利用Lab VIEW实现。监控软件用来接收并显示主控节点发来的温度和GPS定位等数据,为远程监控中心提供实时的冷链信息。在系统软硬件实现的基础上,本文对整个冷链监测系统进行调试与验证。首先,对系统的各个功能进行单独测试,包括Zig Bee传输性能测试、Zig Bee组网实验、以太网测试和通过U盘进行固件升级等实验。然后对温度的测量进行了误差分析与处理。最后,对整个系统进行联调和测试。结果表明,本文对冷链监测系统的研制实现了预期的需求和目标。更多还原

【Abstract】 Blood transfusion is an essential part of modern health care, and it helps to save millions of lives every year. The high-quality storage and transportation of blood and blood products is very important for the clinical use. It’s essential to use the real-time monitoring system of blood cold chain in order to ensure the safety and reliable quality of blood and blood products.Through the analysis of domestic and foreign research situation and performance of cold chain monitoring system, this paper presents a monitoring system based on Zig Bee and GPRS in cold chain. The system is consisted of collector node and the master node. The collector node collects the temperature data of monitored objects. The temperature data of collector nodes are aggregated to the master node through Zig Bee. Then these data are stored in local SD card for backup. At the same time, the remote monitoring center receives data from the master node through GPRS network.This paper detailed elaborates the implementation process of cold chain monitoring system hardware. Firstly, the main devices are selected appropriately. The TI CC2530 is used for Zig Bee. And the STM32F107 RC is used for the master node.Secondly, this paper elaborates the hardware design of collector node, master node and router node.The software design of monitoring system consists of hardware drivers and remote monitoring software. The hardware drivers include GPS, GPRS, USB, SD card, Ethernet, UART and Zig Bee. The remote monitoring software which is programmed by Lab VIEW receives and displays the temperature and GPS data.Based on the implementation of the system hardware and software, this paper did a variety of tests. Firstly, the Zig Bee network is tested. It’s concluded of the function of collector node and the master node.The result shows that the development of cold chain monitoring system achieved the expected requirements and objectives.更多还原
