[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 緯 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.
