The invention relates to the technical field of nuclear power station radiation protection, and provides an early warning system based on nuclear power station isolation boundaries. The system comprises an early warning device and a mounting device. The early warning device is arranged on the mounting device and comprises a device shell, a visual warning module, a mobile living body detection module, a control module, a sound warning module and a power supply module. The visual warning module is used for carrying out real-time warning on an isolation boundary site. The mobile living body detection module is used for generating a trigger signal and sending trigger information to the control module when a mobile living body enters a predetermined area. The control module is arranged in the device shell and used for controlling the sound warning module to give out a preset sound warning according to the received trigger signal. The sound warning module is used for responding to a preset sound warning sent by the control module. The power supply module is arranged in the shell of the shell device and used for providing a working power supply for the early warning device, and the earlywarning system can achieve warning and early warning functions for nuclear power station isolation boundary sites.
Description
technical field [0001] The invention relates to the technical field of nuclear power plant radiation protection, in particular to an early warning system based on nuclear power plant isolation boundaries. Background technique [0002] For the daily work of nuclear power plants, some of the work areas involve the radiation of certain rays, where the radiation radiation is, for example, the radiation radiation during radiographic flaw detection. As a non-destructive testing technology commonly used in industry, radiographic flaw detection uses a beam of uniform intensity to illuminate an object. If there is a defect or a difference in structure in a local area of the object, the intensity of the ray transmitted through the area will be changed. In this way, a certain detector is used to detect The intensity of the transmitted rays can determine whether there are defects inside the object or analyze the material distribution inside the object, but the rays radiated during thi...
