Nuclear monitoring system and method based on confounding sensor network

Abstract

The present invention relates to environment monitoring and control field of mobile robot, especially to a nuclear monitoring system based on hybrid sensor network and a method thereof. The system according to the invention is composed of a common node, a mobile node, a local base station, a local monitoring center and a remote monitoring center. The sensor node is used for monitoring the nuclear radiation information in the network covering area. The mobile node is used for replacing the working personnel to enter certain occasion which is hard for the entering of person. A background monitoring platform adopts the navigation monitoring based on digital map. The system can finish the accident rescuing operation and can free the people from the dangerous and execrable working environment.

Description

technical field [0001] The invention relates to the fields of environment monitoring and mobile robot control, in particular to a nuclear monitoring system and method based on a hybrid sensor network. Background technique [0002] The nuclear and radiation monitoring system mainly includes two categories: one is fixed-point monitoring, which mainly installs nuclear monitoring equipment for nuclear power plants and nuclear radiation facilities; the other is emergency monitoring, such as nuclear attacks in wartime or after terrorist nuclear attacks. Monitoring, estimating and predicting the damage results of nuclear and radiation attacks based on the monitoring results, so as to make decisions on the next action plan and put it into practice. [0003] Nuclear monitoring is based on nuclear radiation. The nuclear monitoring system mainly measures various parameters of the nuclear radiation site, such as dose rate, location, time and weather, etc. The measurement results are sen...

Problems solved by technology

[0004] The main problems existing in my country's nuclear and radiation monitoring system at present: the level of system intelligence is still relatively low, most of the existing communication systems are based on wired access, and it is difficult to expand and update facilities; The interruption of the line leads to the failure of the communication line and destroys the data exchange in the system. It takes a lot of time to troubleshoot the fault; moreover, there is a weak link in the traditional nuclear monitoring system, that is, some metal joints of the line itself will be rusted, seeped, Wiring materials are easily corroded, and at the same time, damage by optical radiation and mechanical damage caused by shock waves also occur from time to time

The former cannot adapt to the requirements of information detection in places where people and large equipment are difficult to approach or enter due to terrain and space constraints; the latter is labor-intensive, and when monitoring some unknown places or suspicious objects, it cannot Free people from dangerous and harsh working environments
