【摘要】：核辐射环境监测已经成为一个重要的环境问题。核辐射恐怖事件、核辐射军事战争以及核泄露等迫使各国必须建立有效地核辐射环境监测平台。从区域环境核辐射监测的角度出发，建立一个科学、可靠的无线传感器监测网络，研究沾染区的核辐射情况，对及时准确地掌握核辐射状况、核事故应急防护、降低核事故发生率以及确保核安全具有重大的现实意义。 本课题从区域环境核辐射监测方面着手，采用ZigBee无线技术，设计基于ZigBee无线传感网络的区域环境核辐射监测系统。首先，针对无线传感网络低功耗和低成本的要求，深入分析无线传感器网路架构和ZigBee协议，设计适用于核辐射环境监测的网络拓扑；其次，选取JN5121模块作为ZigBee无线传感器的核心，构建网络硬件平台；再者，重点研究了接收机制、数据发送、网路节点间的协调、网络结构和动态网路管理，并对所构建的ZigBee无线环境监测网络进行软件开发。最后，对系统进行软硬件调试和性能测试。该系统能够实时测量数据，有效地显示现场γ辐射的剂量率，，实现远程控制、现场调控、安防报警以及环境监测等功能。 该区域环境核辐射监测系统具有较好的推广应用价值，通过核放射性元素剂量检测，能够实际准确地提供核辐射信息，为启动应急防护以及确保和安全提供了可靠的数据基础，同时为区域环境核辐射监测提供了一套实用的解决方法。
[Abstract]:Environmental monitoring of nuclear radiation has become an important environmental problem. The nuclear radiation terrorism, the nuclear radiation military war and the nuclear leakage and so on force each country to establish the effective nuclear radiation environment monitoring platform. From the point of view of regional environmental nuclear radiation monitoring, a scientific and reliable wireless sensor monitoring network is established to study the radiation situation in contaminated areas, to grasp the nuclear radiation situation in a timely and accurate manner, and to prevent nuclear accidents from emergency. Reducing the incidence of nuclear accidents and ensuring nuclear safety is of great practical significance. In this paper, the regional environmental nuclear radiation monitoring system based on ZigBee wireless sensor network is designed by using ZigBee wireless technology. Firstly, aiming at the requirement of low power consumption and low cost of wireless sensor network, the architecture of wireless sensor network and ZigBee protocol are deeply analyzed, and the network topology suitable for nuclear radiation environment monitoring is designed. JN5121 module is selected as the core of ZigBee wireless sensor to construct the network hardware platform. Furthermore, the receiving mechanism, data transmission, coordination between network nodes, network structure and dynamic network management are studied. And the ZigBee wireless environment monitoring network software development. Finally, the software and hardware debugging and performance testing of the system are carried out. The system can measure the data in real time, display the dose rate of 纬 radiation effectively, and realize the functions of remote control, field control, security alarm and environment monitoring. The environmental radiation monitoring system in this region has a good application value. Through the dose detection of radioactive elements, it can actually and accurately provide the nuclear radiation information, and provide a reliable data base for emergency protection and ensuring and safety. At the same time, it provides a set of practical solutions for regional environmental radiation monitoring.
