[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0037] Figure 1 It is a schematic flow chart of the automatic calibration method of the ionizing radiation instrument provided by the present invention;

[0038] Figure 2 The invention provides a principle block diagram of an automatic calibration system for an ionizing radiation instrument. DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In order to solve the problems of data recording, uploading, calculation and other storage of existing radiation instruments, the present invention provides an ionizing radiation instrument automatic calibration method and system, which aims to realize the automation of data recording during the calibration process of the radiation instrument, improve accuracy, efficiency and consistency, and realize the automation of data processing after the calibration of the radiation instrument, and simultaneously issue the instrument calibration certificate and original records.

[0041] Specifically, refer to Figure 1 In a preferred embodiment, the automatic calibration method of the ionizing radiation meter comprises the following steps:

[0042] Step S101: Acquire image information of a radiation meter through a smart camera, and perform recognition based on the image information to obtain a label number of the radiation meter.

[0043] Specifically, the radiation meter is imaged through a smart camera to obtain image information of the radiation meter, and the smart camera and the industrial machine are connected to the same network segment through a network connection device, so that the image information used by the smart camera is transmitted to the industrial machine, and the industrial machine recognizes the image information to identify the label number of the radiation meter.

[0044] Step S102: During the calibration process of the radiation instrument, image acquisition and image recognition are performed on the radiation instrument to obtain instrument data.

[0045] In some embodiments, during the calibration process of the radiation instrument, images of the radiation instrument are collected and image recognition is performed to obtain instrument data, including: during the calibration process of the radiation instrument, images of the radiation instrument are collected to obtain instrument images; based on the YoloV5 target detection model, CNN character recognition model and OCR text recognition model, the instrument image is analyzed to obtain instrument data of the radiation instrument.

[0046] Furthermore, in an embodiment of the present invention, before applying the YoloV5 target detection model, CNN character recognition model and OCR text recognition model to analyze the instrument image, the model needs to be trained and optimized, that is, the YoloV5 target detection model and the OCR text recognition model are trained and optimized based on the original recorded data saved after the data recognition is completed after each radiation instrument calibration, and then the YoloV5 target detection model and the OCR text recognition model are integrated to build a complete OCR system. Finally, according to the specific instrument laboratory scenario, it is deployed on an industrial machine. Among them, the parameters and loss function of the model can be optimized by reviewing the past to improve the accuracy and stability of the model.

[0047] Specifically, pre-trained weights (such as the YoloV5 model pre-trained on the COCO dataset) are used for fine-tuning to speed up the training process and improve performance.

[0048] The loss functions used by YoloV5 include bounding box regression loss, confidence loss, and classification loss. It can generally be trained using Adam or SGD optimizers. When adjusting hyperparameters, model performance can be optimized by adjusting hyperparameters such as learning rate, batch size, and data augmentation parameters. Specifically, learning rate scheduling strategies such as cosine annealing and learning rate decay are used for learning rate scheduling. Regularization is performed using techniques such as L2 regularization and Dropout to prevent overfitting. Transfer learning is performed by starting training from pre-trained models of similar tasks to reduce training time and improve performance.

[0049] In the embodiment of the present invention, the prediction results of integrating multiple models have the following advantages:

[0050] Improve the overall prediction performance and robustness. Among them, methods including but not limited to Bagging, Boosting and Stacking can be used for integration.

[0051] Improve fault tolerance. The integrated model can effectively reduce the errors in the prediction of a single model, thereby improving the overall accuracy of the system.

[0052] Enhance the scalability and flexibility of the model. Specifically, modular design: By integrating the model into the system, modular design can be achieved, making the system easier to expand and maintain. Portability: The integrated model can be easily ported to different platforms and environments, enhancing the flexibility of the application.

[0053] Realize practical applications and business needs. Specifically, real-time prediction: deploying the model to the production environment can achieve real-time prediction and decision support to meet business needs. User interaction: by deploying the model, users can interact with the system, such as recommendation systems, speech recognition and other application scenarios.

[0054] Continuous optimization and updating. Feedback loop: By deploying the model to the actual environment, user feedback and new data can be collected to further optimize and update the model. Performance monitoring: After deployment, the performance of the model can be monitored in real time to promptly discover and solve problems and ensure the stability and reliability of the model.

[0055] Step S103: Analyze and calculate the instrument data to obtain data processing results.

[0056] In some embodiments, analyzing and calculating the instrument data to obtain the data processing results includes: judging abnormal data on the instrument data; if abnormal data exists, marking and removing the abnormal data, and outputting a data abnormality reminder; if no abnormal data exists, analyzing and calculating the instrument data to obtain the data processing results.

[0057] Step S104: Generate an instrument calibration certificate and original records based on the data processing results and instrument data.

[0058] In some embodiments, generating an instrument calibration certificate and original records based on data processing results includes: judging the instrument performance of the radiation instrument based on the data processing results; if the radiation instrument does not meet the restriction conditions, outputting an unqualified prompt; if the radiation instrument meets the restriction conditions, generating an instrument calibration certificate and original records based on the data processing results and the instrument data.

[0059] Among them, generating an instrument calibration certificate and original records based on data processing results and instrument data includes: using Python tools to capture data processing results and instrument data into an instrument calibration certificate template and an original record template; and generating an instrument calibration certificate and original records of a radiation instrument based on the instrument calibration certificate template and the original record template.

[0060] Specifically, after the instrument data of the radiation instrument is identified, the instrument data is filled into an Excel table with set rules and templates, and then the Python tool is used to simulate the manual automatic generation of the instrument calibration certificate and original records.

[0061] Among them, the Laida criterion can be used to identify abnormal data. That is, the Laida criterion is set in an Excel table to mark and remove abnormal values. Among them, the Laida criterion is:

[0062] |x d -x|≧3s;

[0063] That is, when the above conditions are met, the data is judged to be abnormal data, otherwise it is not abnormal data.

[0064] After the abnormal data is identified, the quality of the radiation instrument is determined based on the instrument data. Specifically, the instrument performance requirements specified in the instrument verification regulations (such as relative inherent error, repeatability, statistical fluctuations, surface emissivity response, etc.) are set as constraints in the Excel table of the instrument calibration certificate template, and the calculated data processing results are compared with the constraints. If the instrument performance requirements specified in the regulations are exceeded, the data is determined to be unqualified. At this time, the color of the corresponding data box turns red, thereby achieving the purpose of reminding the data of unqualified and completing the metrological technical identification of the radiation instrument.

[0065] Further, in an embodiment of the present invention, the automatic calibration method for an ionizing radiation instrument further includes: storing the generated instrument calibration certificate and original records. Storing the generated instrument calibration certificate and original records includes: storing the instrument calibration certificate and original records in a database or a file system. By using a database or a file system for storage, the security and integrity of the data can be ensured, which is convenient for subsequent analysis and use.
