Abstract

The invention discloses a nuclear power plant equipment monitoring system based on a wireless sensor network. A wireless monitoring node for gridding an equipment monitoring surface, obtaining tenth-order vibration mode inherent frequency and total displacement modal data of primarily selected monitoring points of important equipment to be monitored of the nuclear power plant, selecting optimized points by use of an intelligent optimization algorithm and collecting the monitoring information of nuclear power plant equipment monitoring terminals; a wireless relay node is used for gridding a spatial range in which the relay node is possibly deployed and primarily forming virtual redundant multi-route paths on the basis of the wireless monitoring node and further used for receiving the monitoring information data of the wireless monitoring node; a gateway and network access node is used for transmitting the monitoring information data to background monitoring software for processing; the background monitoring software is used for processing the monitoring information data and sending the processing result to a client and various monitoring terminals. The nuclear power plant equipment monitoring system based on the wireless sensor network is capable of meeting the special requirements such as high safety and high reliability in the application scenes of the nuclear power plant.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant equipment monitoring, and relates to a nuclear power plant equipment monitoring system based on a wireless sensing network. Background technique [0002] At present, the world's energy prices are soaring, the greenhouse effect is intensifying, and the energy supply and demand situation is deteriorating. Energy shortages and environmental issues have become the main body of global energy issues. It is an inevitable choice to vigorously develop resource-rich and clean nuclear power. At present, the production process, industrial control, equipment monitoring and maintenance in nuclear power plants mainly use wired communication technology. However, there are many problems in the traditional wired method, such as environmental constraints on wiring, expensive cables, difficult maintenance, etc., which limit the scope and methods of wired technology applications. In addition, the goal of ...
