However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0025] like Figure 1As shown, in one of the embodiments, the nuclear electric anti-radiation temperature detection device of the present embodiment comprises an anti-radiation measurement probe 10, a double-layer heat insulation structure 20, a data processing system 30, a display screen 40, and a power module 50 for providing working power for the device. The double-layer heat insulation structure 20 is wrapped around the anti-radiation measurement probe 10. The anti-radiation measurement probe 10 is used to detect the radiation signal and temperature signal of the current environment at the determined detection position. The data processing system 30 is electrically connected with the anti-radiation measurement probe 10, used to receive and analyze the collected radiation signal and temperature signal, and display the processing result through the display screen 40. The power module 50 is connected with the anti-radiation measurement probe 10, the data processing system 30, and the display screen 40 respectively, and can supply power for the entire device, providing power support.

[0026] It can be understood that the anti-radiation measurement probe 10 has a total radiation sensor probe and a temperature sensor probe, which are packaged in the same shell in a split manner. The anti-radiation measurement probe 10 is made of nickel-based alloy material, ceramic material, or carbon fiber composite material. That is, the probe material is made of nickel-based alloy, which has the properties of high temperature resistance, radiation resistance, and anti-radiation. In addition to special alloy materials, other materials with excellent anti-radiation performance can also be selected as the anti-radiation material of the probe, such as ceramic materials, carbon fiber composite materials, etc.

[0027] The double-layer heat insulation structure 20 is formed by bonding two layers of heat insulation materials of the same material. The heat insulation material is a vacuum heat insulation layer or a multi-layer heat insulation film. That is, the double-layer heat insulation structure 20 can adopt different materials and structural forms, such as vacuum heat insulation layer, multi-layer heat insulation film, etc., to meet the heat insulation needs in different environments. In this embodiment, the double-layer heat insulation structure 20 can protect the internal temperature sensor and electronic components, reduce the direct impact of radiation on the temperature sensor, improve stability, and slow down the transmission of external temperature sudden changes.

[0028] On the basis of the above-mentioned embodiments, the structure of the anti-radiation measurement probe 10 can be further optimized, and a multi-layer composite material design can be adopted to improve the anti-radiation performance while enhancing the mechanical strength and durability of the probe. It should be noted that the multi-layer composite material can use existing technical materials, which will not be described here.

[0029] In this embodiment, the data processing system 30 can also obtain actual irradiance and actual temperature values by analog-to-digital conversion of the radiation signal and the temperature signal. According to a preset calibration algorithm and a preset correction rule, the actual irradiance and the actual temperature values are subjected to automatic calibration and error correction processing in sequence. Optionally, the data processing system 30 can also compare the currently collected data with historical data to realize fault self-diagnosis and alarm. The data processing system 30 with the function of fault self-diagnosis can discover and handle device faults in time, and improve the reliability and safety of the system.

[0030] It should be noted that the automatic calibration is a data preprocessing after data collection, and the calibration model is used for calibration after denoising (which can be achieved by filtering technology) and missing value processing (which can be achieved by interpolation technology) in the preprocessing stage. The automatic calibration algorithm is based on a statistical method (least squares method), and the sensor will be continuously detected subsequently. The error correction is also denoising after collection, and rule correction (such as threshold correction) is performed thereon. That is, the function implementation of the data processing system 30 of the present application is based on related algorithms in the prior art, and the core improvement lies in the optimization of the hardware structure to improve the processing efficiency and stability. The algorithm in the data processing system 30 can be optimized and adjusted according to the actual application scene to improve the measurement accuracy and data processing efficiency.

[0031] The working principle of the nuclear electric anti-radiation temperature detection device of the present embodiment is as follows: a detection position is determined, the anti-radiation measurement probe 10 is placed in the detection position, the anti-radiation measurement probe 10 detects the actual temperature value and the actual radiation amount of the current environment, and sends the collected data to the data processing system 30. The data processing system 30 receives the data and performs automatic calibration on the data to obtain calibrated data, performs error correction processing on the calibrated data to obtain corrected data, uploads the corrected data to the upper computer through the remote communication module 60, and displays the corrected data on the display screen 40.

[0032] The present embodiment can ensure that the probe stably and accurately measures the temperature in a high-radiation environment, effectively isolates the influence of the external environment on the measurement probe, improves the measurement accuracy, and improves the accuracy of the measurement results through real-time analysis and processing of the measurement data.

[0033] In some embodiments, reference is made to Figure 2The nuclear electric anti-radiation temperature detection device of the embodiment can further include a remote communication module 60 connected with the data processing system 30, and the remote communication module 60 is used to transmit relevant data of the data processing system 30 to a gateway or an upper computer. It can be understood that the relevant data includes but is not limited to device state, collected data, processing result data and / or data transmission state device running state. The upper computer detects the device running state according to the device state, diagnoses the fault, monitors the network connection of the data transmission state and checks the data integrity. The anti-radiation measurement probe made of special material in the embodiment has very high anti-radiation performance and can maintain stable measurement performance in a high radiation environment. The double-layer thermal insulation layer is designed to effectively isolate the influence of the external environment on the measurement probe and ensure the measurement accuracy. The integrated data processing module analyzes the measurement data in real time, automatically calibrates and corrects errors, and improves the measurement accuracy. The remote communication module is equipped to realize remote real-time monitoring and data transmission and improve the safety management level of the nuclear power plant.

[0034] In a specific embodiment, regarding the signal processing procedure, the sensor signal of the probe is processed by a low-power single-chip microcomputer after analog-to-digital conversion (ADC) and displayed by LCD or generated into a table / curve by supporting software. For example, the host of H17694 adopts a Chinese menu interface and supports real-time viewing and statistical functions. Regarding sensor integration, the SOLAR02 remote measurement unit can simultaneously connect three radiation probes (such as total radiation sensors) and PT300N temperature probes, communicate with the host device through USB or radio frequency (RF), and display the irradiance and temperature values in real time. Regarding the dual-mode detection structure, the optical fiber temperature sensor detects the temperature through fluorescence lifetime in the low-temperature zone (<400℃) and calculates the temperature through radiation signal strength in the high-temperature zone (>400℃). The system includes Y-type quartz optical fiber, ultra-high brightness LED, photodetector and separate fluorescence / radiation signal processing modules. The blackbody cavity coating and Cr 3 + ion doping optimize signal separation, reduce the mutual interference of fluorescence and radiation signals, so as to realize the anti-interference design of the detection device.

In this embodiment, the nuclear electric anti-radiation temperature detection system includes an anti-radiation measurement probe, a double-layer thermal insulation structure, a data processing system, a remote communication module, a power module, a display screen, and the host computer 3 and / or the gateway 2.

The double-layer thermal insulation structure is composed of materials with good high-temperature resistance and thermal insulation performance, which ensures that the measurement probe is not affected by the external environment. The data processing system can process measurement data in real time and automatically calibrate. The remote communication module supports wireless or wired communication and realizes remote monitoring. Optionally, the remote communication module can first transmit relevant data to the gateway 2, and then transmit the data to the host computer 3 through the gateway 2 for monitoring, which can make the host computer 3 avoid the construction work of the base as much as possible. Of course, the remote communication module can also directly transmit relevant data to the host computer 3. The power module uses high-efficiency batteries to ensure stable operation of the device for a long time. The display screen is used to display measurement data and device status in real time. The remote monitoring content of the host computer 3 includes but is not limited to temperature data monitoring, radiation level monitoring, and device status monitoring, fault diagnosis, fault alarm, etc.
