Method for distributing wireless sensor nodes for nuclear pollution detection

Abstract

The invention discloses a method for distributing wireless sensor nodes for nuclear pollution detection. A ground high-mobility mobile reconnaissance robot provided with mechanical arms serves as a platform, and nuclear detection wireless sensor nodes are carried to enter a nuclear pollution site. The nuclear detection wireless sensor nodes are taken out of a box by utilizing the mechanical arms and are arranged at a detection place, and a switch of the nuclear detection wireless sensor nodes is turned on for detection; after the nodes are distributed, far-end detection personnel can determine an area with the highest polluted degree according to a detection value of the nuclear detection wireless sensor nodes and control the robot to enter the area so as to find a pollution source; and after the detection task is ended, the robot returns to the previous node distributing position according to global position system (GPS) positioning, and the nodes are closed and recovered into the box one by one. By the method, the working efficiency of the nuclear detection in a wide-range polluted area is greatly improved, and the nuclear radiation pollution degree in the polluted area can be rapidly and accurately found out.

Description

1. Technical field [0001] The invention relates to the field of nuclear pollution detection, in particular to a method for distributing wireless sensor nodes for nuclear pollution detection. 2. Background technology [0002] In the current nuclear accident handling and nuclear anti-terrorism operations, the use of portable, vehicle-mounted and airborne nuclear detection equipment in the implementation of nuclear detection tasks requires personnel to enter the site for operations, and it is necessary to complete complex areas or large-scale equipment and personnel cannot enter There are certain difficulties in the nuclear detection missions carried out in the region. In order to reduce casualties, it is necessary to use small mobile reconnaissance robots to enter the scene through wireless control, equipped with nuclear detection instruments, and send back the data, sound, images and other information measured by the instruments on site in real time, providing a basis for on-...

AI Technical Summary

Problems solved by technology

However, if it is necessary to detect the degree of nuclear pollution in a large area, it will expose the shortcomings of the low efficiency of the above-mentioned technical work, not only the working time is long, but also there are a large number of repeated detection paths

When the detection instrument needs to be replaced, the teleoperated mobile robot must first return to the safe working area. After manually replacing the detection instrument, re-enter the on-site detection, which consumes a lot of precious time and affects the progress of nuclear chemical detection.

At the same time, this method can only find nuclear radioactive sources after a large number of repeated detection paths, but cannot form a distribution map of nuclear radiation levels, and cannot provide a more intuitive basis for rescuers' decision-making command and personnel evacuation
