[0002] In terms of the control of high radiation risk work, nuclear power plants have taken many measures to confirm the radiation safety of operators, but the existing control measures rely more on the risk awareness and skills of radiation workers. Both operations and supervision still rely too much on people's subjective initiative, and there are certain deficiencies in technical means. Taking radiographic flaw detection as an example, most nuclear power plants still use traditional isolation methods when performing the control of radiation isolation boundaries for radiographic flaw detection operations, that is, setting up isolation columns, setting up isolation belts, and arranging special personnel on duty to control the flaw detection area. At present, nuclear power plants adopt this method for the control of radiation boundaries for radiographic flaw detection. This traditional control method completely relies on the subjective initiative of the on-duty personnel, cannot monitor the radiation dose of the boundary in real time, lacks the necessary means of personnel intrusion alarm, and there is a risk of personnel accidentally intruding into the isolation boundary, which is not conducive to the radiation safety control of the operation.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] At least one embodiment of the present application provides an intelligent control device for radiation boundaries of radiographic flaw detection, which is mainly used for safety control of radiation isolation boundaries during radiographic flaw detection operations in nuclear power plants.

[0020] refer to Figures 1 to 3 The intelligent control device for radiation boundary of radiographic flaw detection includes a supporting component and a control component located above the supporting component. The control component includes a shell and an acoustic and optical alarm module integrated in the shell, a radiation detection module, a display unit, a laser module, a human infrared detection module, a camera intrusion alarm module, a data processing center and a host computer control module. The host computer control module is connected to the display unit and the data processing center, and is used to receive signals from the display unit and the data processing center, and process and filter the signals from the display unit and the data processing center, process the current radiation dose threshold of the display unit monitoring data, and display it through the display unit.

The laser module is used to mark the boundary of the radiation area and update the boundary information in real time. The host computer control module is used to write and compare the radiation monitoring threshold, and to screen and integrate the data transmitted by the data processing center and then send it to the data processing center for processing.

[0021] It should be noted that the laser module and the power module are both independent working modules. The human infrared detection module is a mobile living body intrusion detection module. The radiation monitoring module can monitor the radiation dose at the boundary in real time.

[0022] The working principle of the laser module is based on the synergy of the laser emitter and the optical system. The laser emitter generates a stable laser beam, while the optical system is responsible for guiding the laser beam to the predetermined position to form the required boundary line. By controlling the power of the laser emitter and the configuration of the optical system, the laser module can generate laser lines of different colors and thicknesses to adapt to different working environments and needs. In the process of X-ray flaw detection, the application of laser modules can significantly improve work efficiency and safety.

[0024] According to the technical solution provided by the embodiment of the present application, by using the radiation detection module to monitor the radiation dose of the boundary in real time, and using the human infrared detection module to monitor the intrusion of personnel at the boundary in real time, when the personnel enter the sensing area of ​​the radiation boundary intelligent control device of the radiographic flaw detection, it is timely discovered that the personnel have mistakenly entered the isolation boundary, and the sound and light alarm module continuously performs sound and light alarms and voice prompts to remind the security control personnel to pay attention, and record the video at the same time, thereby realizing real-time monitoring of the radiation level at the boundary, and performing real-time monitoring and alarm of personnel intrusion while playing a safety warning role, assisting the intelligent safety control of the boundary, realizing real-time control of the radiation boundary of the radiographic flaw detection operation, and improving the radiation safety control performance of the radiographic flaw detection operation. In addition, by using the laser module to adjust the position and shape of the laser line in real time, the laser module can accurately mark the boundary of the radiation area to prevent personnel from mistakenly entering the dangerous area, and the rapid response capability of the laser module enables the boundary information to be updated in real time during the radiographic flaw detection process, ensuring that the radiation boundary intelligent control device of the radiographic flaw detection always maintains accurate control of the radiation area.
