Accelerator industrial CT safety interlocking logic

 

I. Introduction

 

Accelerator industrial Computed Tomography (CT), as an advanced non-destructive detection technology, plays an important role in the industrial field. However, due to its use of high-energy particle beams for scanning, there are certain radiation safety risks. In order to ensure the safety of workers, equipment and the surrounding environment, the accelerator industrial CT system must be equipped with a complete safety interlocking system. The purpose of this paper is to elaborate the construction and application of safety interlocking logic relation of CT in accelerator industry.

Ii. Overview of accelerator industrial CT safety interlocking system

 

Accelerator Industrial CT Safety Interlocking system refers to a combination of safety devices and control logic used to monitor and control potential safety risks during accelerator operation. By monitoring various safety parameters, such as radiation dose, equipment status, personnel location, etc., the system can automatically or manually control the operating status of the accelerator to ensure that safety measures can be taken quickly in abnormal situations to prevent accidents.

 

Third, the construction of accelerator industrial CT safety chain logic relationship

 

Selection and monitoring of safety parameters

The safety parameters that need to be monitored in the accelerator industrial CT safety interlocking system include radiation dose, equipment temperature, pressure, current, voltage, etc. These parameters are monitored in real time by sensors, and the data is transmitted to the control system for analysis and processing. When any safety parameter exceeds the preset safety threshold, the control system will trigger the corresponding safety chain action.

 

Definition and implementation of security interlocking action

According to the different safety parameters, accelerator industrial CT safety interlocking system needs to define the corresponding safety interlocking action. These actions include, but are not limited to:

(1) Emergency shutdown: When the radiation dose exceeds the safety threshold, the control system will immediately cut off the power of the accelerator and stop its operation to avoid radiation leakage.

 

(2) Equipment protection: When the equipment temperature, pressure and other parameters exceed the safe range, the control system will take corresponding measures, such as reducing power, increasing cooling, etc., to protect the equipment from damage.

 

(3) Personnel protection: When personnel are detected to enter the dangerous area, the control system will trigger the audible and visual alarm device to remind the personnel to evacuate, and automatically take safety measures such as emergency shutdown.

 

(4) Fault recovery: When the system detects a fault, it will automatically carry out fault diagnosis and recovery operations to reduce downtime and losses.

 

In order to realize these safety interlocking actions, the accelerator industrial CT safety interlocking system needs to adopt reliable hardware and software technology. In terms of hardware, the system should choose high-performance controllers, sensors and actuators and other key components to ensure the stability and reliability of the system. In terms of software, the system should adopt modular and hierarchical design ideas to achieve loose coupling and easy expansibility between various functional modules. At the same time, the system should support remote monitoring and fault diagnosis functions to detect and deal with potential security risks in a timely manner.

 

Establishment of security chain logic relationship

The establishment of safety interlocking logic relationship of accelerator industrial CT is the key to ensure the safety of the system. In the safety chain logic relationship, each safety parameter and chain action should form a relationship of mutual correlation and mutual restriction. When a security parameter is abnormal, the corresponding chain action is triggered, and other related parameters and actions are taken into account through logical relationships. For example, when the radiation dose exceeds the safety threshold, in addition to immediately cutting off the accelerator power, it should also shut down the relevant equipment and start the alarm device. This interconnected and mutually restrictive logic ensures that the system can quickly take comprehensive safety measures to prevent accidents in the event of an anomaly.

 

Iv. Application and optimization of accelerator industrial CT safety interlocking system

 

System application

Accelerator industrial CT safety interlocking system should meet the following requirements in practical application:

 

(1) Reliability: The system should be able to operate stably in a variety of complex environments, and accurately monitor and control various safety parameters.

 

(2) Real-time: The system should be able to monitor the changes of various security parameters in real time, and quickly take security measures in abnormal circumstances.

 

(3) Ease of use: The system should have a friendly user interface and operation process, convenient for users to carry out daily operation and maintenance.

 

(4) Scalability: The system should support modular and hierarchical design ideas to facilitate the expansion and upgrade of subsequent functions.

 

System optimization

To improve the performance of the accelerator industrial CT safety interlocking system, the following optimization measures can be taken:

 

(1) Optimization algorithm: advanced control algorithm and data processing technology are adopted to improve the response speed and accuracy of the system.

 

(2) Upgrade hardware: Select more advanced controllers, sensors and actuators and other key components to improve the stability and reliability of the system.

 

(3) Improve the function: according to user needs and technical development, constantly improve the function of the system, improve the practicality and ease of use of the system.

 

(4) Strengthen training: strengthen training and technical support for users, and improve users' ability to use and maintain the system.
