[0034] The X-ray detection control system includes an intelligent detection processing unit, the input end of the intelligent detection processing unit is connected to an X-ray parameter setting unit, a detection parameter setting unit, a station collection unit, a test data collection unit and a dual-start instruction collection unit, and the output end of the intelligent detection processing unit is connected to an intelligent detection control unit, a safety protection unit, a status display unit and a detection data output unit;

[0035] The input ends of the X-ray parameter setting unit and the detection parameter setting unit are both connected to the parameter button signal arranged at the front end of the control box, the input end of the standing person collection unit is connected to the weight sensor signal arranged in the weight sensing mat 4, the input end of the inspection data collection unit is connected to the X-ray detector 2 signal, and the input end of the dual start command collection unit is respectively connected to the internal linkage button 21 and the external linkage button 11 signal;

[0036] The output end of the intelligent detection and control unit is connected to the signal of the X-ray detector 2, the output end of the safety protection unit is connected to the signal of the protection component 5, the output end of the status display unit is connected to the signal of the sound and light display arranged on the upper end of the radiation shield 1, and the output end of the detection data output unit is connected to the external PC terminal signal through the wiring harness at the rear end of the X-ray detector 2. Through the cooperation of the weight sensing floor mat 4, the protection component 5 and the X-ray detection control system, on the one hand, it can realize the real-time monitoring of whether there is a person standing inside the radiation shield 1, promote the automation and intelligence of the X-ray detection equipment, and ensure the safety of the X-ray detection equipment during the application process. On the other hand, it effectively realizes the double-start verification of the safety of the startup action of the X-ray detector 2, further ensures the application safety of the X-ray detection equipment, avoids radiation damage to the inspector due to misoperation, and improves the safety protection function of the X-ray detection equipment through intelligent control, thereby effectively improving the application and development of the X-ray detection equipment and increasing the economic benefits of the X-ray detection equipment.

[0037] Figure 1 - Figure 6It is shown that a protective embedding groove 12 is opened at the front end of the radiation shield 1, and the protective embedding groove 12 is located on the outer side of the rear end of the external linkage button 11. The protection component 5 includes a protective support sleeve 51 fixedly connected to the rear inner wall of the protective embedding groove 12, and the front end of the protective support sleeve 51 is fixedly connected to the external linkage button 11.

A tension spring 54 is fixedly connected between the two anti-closing electromagnetic blocks 53, and the stiffness coefficient of the tension spring 54 is less than or equal to the stiffness coefficient of the reset part in the external linkage button 11. The cooperation between the anti-closing electromagnetic block 53 and the safety protection unit can effectively further ensure the application safety of the X-ray detection equipment according to the data of whether there is a person standing in the radiation protection cover 1. When there is a person standing in the radiation protection cover 1, the elongation effect of the protective support sleeve 51 is maintained, and the external linkage button 11 can be forced to be supported, which can effectively avoid the external linkage button 11 from being miscontrolled, and ensure the safety of the inspectors in the radiation protection cover 1. When there is no one standing in the radiation protection cover 1, the forced support effect of the protective support sleeve 51 on the external linkage button 11 can be automatically released, so that the external linkage button 11 can be effectively operated and controlled by the inspectors, thereby ensuring the functionality of the external linkage button 11.

[0038] Figure 1 , Figure 2 , Figure 7 and Figure 8 It is shown that the output end of the intelligent detection processing unit is also connected to a door lock unit, and the output end of the door lock unit is connected to an electromagnetic automatic lock signal provided on the external linkage button 11 and matched with the radiation-proof sliding door 3;

[0039] The output end of the station person collection unit is also connected to the door lock unit and the safety protection unit signal, and the output end of the door lock unit is also connected to the safety protection unit signal;

[0040] The input end of the intelligent detection processing unit is also connected to a closed instruction acquisition unit, and the input end of the closed instruction acquisition unit is connected to the door lock button signal arranged at the front end of the radiation-proof sliding door 3. The cooperation of the door lock unit, the standing person acquisition unit, the safety protection unit and the closed instruction acquisition unit can effectively realize the coordination between the units. Through the coordinated locking and verification of each unit, the safety of the X-ray detection equipment during the application process is effectively guaranteed, and the intelligent safety protection function of the X-ray detection equipment is promoted.

[0041] Figure 1 , Figure 2 , Figure 7 and Figure 8It is shown that the input end of the intelligent detection processing unit is also connected to a standing person data verification unit, and the input end of the standing person data verification unit is connected to the camera signal arranged on the inner wall of the radiation protection cover 1. The setting of the standing person data verification unit can effectively assist the standing person acquisition unit to verify the data of the state inside the radiation protection cover 1, improve the judgment accuracy of the intelligent detection processing unit, reduce the probability of unit loss of control in the X-ray detection equipment, and effectively ensure the stability and safety of the operation of the X-ray detection equipment.

[0042] Figure 1 , Figure 2 , Figure 7 and Figure 8 It is shown that the input end of the intelligent detection processing unit is also connected to the infrared sensor of the workpiece sensing unit set at the end of the X-ray detection machine 2, which senses and confirms the position of the workpiece. The input end of the workpiece sensing unit is connected to the infrared sensor signal set at the end of the workbench of the X-ray detection machine 2. The setting of the workpiece sensing unit can effectively verify and confirm the position of the workpiece placed on the workbench of the X-ray detection machine 2, and effectively ensure the efficiency and accuracy of the subsequent inspection by the X-ray detection machine 2.

[0043] Figure 1 - Figure 8 It is shown that in the process of using the X-ray detection equipment, the inspector inputs an unlocking instruction to the closed instruction acquisition unit through the door lock button at the front end of the radiation shield 1, and the closed instruction acquisition unit transmits the unlocking instruction to the intelligent detection processing unit. The intelligent detection processing unit sends an unlocking control to the door lock unit, so that the door lock unit controls the electromagnetic automatic lock to release the lock of the radiation protection sliding door 3. Then the inspector opens the radiation protection sliding door 3 to enter the radiation shield 1, and places the workpiece to be detected on the workbench of the X-ray detection machine 2. The inspector inputs relevant parameters about X-rays and detection to the X-ray parameter setting unit and the detection parameter setting unit respectively through the parameter buttons set on the control box according to the specifications and quality requirements of the workpiece to be detected. The X-ray parameters include but are not limited to the relevant data parameters such as the radio frequency, range and radiation duration of the X-ray, and the detection parameters include the relevant data parameters such as the workpiece position, moving range and speed, and detection accuracy. Then the X-ray parameter setting unit and the detection parameter setting unit process the received data and transmit them to the intelligent detection processing unit;

[0044] When the inspector is in the radiation shield 1 and sets parameters, he stands on the upper end of the weight sensing mat 4, so that the weight sensor in the weight sensing mat 4 transmits data to the standing person collection unit, and the standing person collection unit transmits the standing person data in the radiation shield 1 to the intelligent detection processing unit, and also transmits the standing person data to the door lock unit and the safety protection unit, and after the door lock unit receives the unlocking instruction of the intelligent detection processing unit and the standing person data transmitted by the standing person collection unit, the unlocking state data is transmitted to the safety protection unit, and after receiving the standing person data, the door lock unit maintains the normally open control of the electromagnetic automatic lock, and after receiving the standing person data and the unlocking state data, the safety protection unit passes current into the anti-closing electromagnetic block 53, so that the two anti-closing electromagnetic blocks 53 generate electromagnetic repulsion forces away from each other, and then under the coordinated action of the tension spring 54, the external linkage button 11 is forced to open, thereby increasing the resistance of the external linkage button 11 to being pressed and triggered, thereby effectively avoiding the problem of the external linkage button 11 being triggered by mistake and causing damage to the inspector inside the radiation shield 1;

[0045] Then, after the inspector inside the radiation shield 1 has placed the workpiece to be inspected and set the parameters, he presses the internal linkage button 21 on the control box, and then walks out of the radiation shield 1 through the radiation shield sliding door 3. The weight sensor in the weight sensing mat 4 no longer senses the standing person data, so the weight data after data recovery is sent to the standing person acquisition unit. The standing person acquisition unit transmits the data of no standing person to the intelligent detection processing unit. The inspector closes the radiation shield sliding door 3 and presses the door lock button at the front end of the radiation shield 1. The door lock button transmits the button instruction to the closing instruction acquisition unit. After the closing instruction acquisition unit transmits the locking instruction to the intelligent detection processing unit, the camera inside the radiation shield 1 transmits the image data inside the radiation shield 1 to the standing person data verification unit. The standing person data verification unit transmits the image data inside the radiation shield 1 to the intelligent detection processing unit. The intelligent detection processing unit verifies the received no standing person data. After verifying that the no standing person data is incorrect, the door lock closing instruction is not executed, and The state display unit controls the function of the sound and light display, and by issuing an abnormal sound and light warning, the operator or the inspector who is still in the radiation shield 1 is reminded to avoid safety damage caused by misoperation; after verifying that the non-standing data is accurate, the intelligent detection processing unit transmits the lock control data to the door lock unit, and while the standing data collection unit transmits the non-standing data to the intelligent detection processing unit, it also cuts off the standing data transmitted to the door lock unit and the safety protection unit respectively, so that after the door lock unit receives the lock instruction from the intelligent detection processing unit and no longer receives the standing data from the door lock unit, it controls the electromagnetic automatic lock to close and close the radiation protection sliding door 3. After the safety protection unit no longer receives the standing data, the current passed into the anti-closing electromagnetic block 53 is cut off, causing the anti-closing electromagnetic block 53 to lose its magnetic repulsion effect, and the external linkage button 11 only maintains a constant disconnection effect under the action of the tension spring 54, so that the external linkage button 11 is operable at this time;

[0046] After pressing the door lock button, the inspector presses the external linkage button 11 and compresses the tension spring 54 and the protective support sleeve 51, so that the external linkage button 11 can be pressed and triggered normally, and the double start instruction acquisition unit can receive the start data of the external linkage button 11, and the double start instruction acquisition unit transmits the double start data of the external linkage button 11 and the internal linkage button 21 to the intelligent detection processing unit. After receiving the single and double start data, the intelligent detection processing unit uses the infrared sensor to sense the position of the workpiece to be detected on the workbench, and then transmits the sensing data to the workpiece sensing unit. The workpiece sensing unit transmits the data to the intelligent detection processing unit. After determining that the position of the workpiece to be detected is incorrect, the intelligent detection processing unit controls the sound and light display to generate an abnormal warning through the status display unit, and outputs the abnormal data to the PC through the detection data output unit, so that the inspector can re-operate to enter the radiation shield 1 according to the PC and the abnormal sound and light display, check the position of the workpiece to be detected, and set the detection parameters. A check is performed regularly to ensure that the workpiece to be inspected maintains data consistency with the inspection parameters, and then the external linkage button 11 is started again; after the intelligent detection processing unit determines that the position of the workpiece to be inspected is correct, a control instruction is issued to the intelligent detection control unit, so that the intelligent detection control unit controls the X-ray detection machine 2 to start, and inspects the workpiece to be inspected. The inspection data acquisition unit collects the inspection data of the X-ray detection machine 2, and transmits it to the intelligent detection processing unit after conversion. The intelligent detection processing unit will output the inspection data to the PC through the inspection data output unit for display, so that the inspector can check the inspection structure. During the execution of the X-ray detection machine 2, the intelligent detection processing unit will act on the sound and light display through the status display unit, and prompt the inspector to the inspection status by generating different sound and light effects, so that the inspector can judge whether the inspection process is normal or not, as well as the completion status of the inspection, which can effectively realize the inspector's long-distance observation of the X-ray detection equipment and ensure the safety of the inspector during the inspection process.

[0047] When the X-ray detection equipment is not in use, the inspector closes and locks it. At this time, the intelligent detection processing unit controls the electromagnetic automatic lock to permanently lock the radiation-proof sliding door 3 through the door lock unit, and also transmits the protection data to the safety protection unit, so that the safety protection unit can control the two anti-closing electromagnetic blocks 53 to maintain a constant electromagnetic repulsive force, force the external linkage button 11 to open, increase the resistance of the external linkage button 11 being pressed and triggered, and effectively realize the locking effect of the X-ray detection equipment, thereby further ensuring the safety of the X-ray detection equipment.

[0048] Second implementation method:

[0049] Figure 1 - Figure 8A high-security modular X-ray detection device is shown. The output end of the intelligent detection processing unit is also connected to a ventilation control unit. The output end of the ventilation control unit is connected to the ventilation structure signal arranged in the radiation shield 1, and the input end of the ventilation control unit is also respectively connected to the standing person collection unit and the intelligent detection control unit signal. The ventilation structure includes a ventilation fan, a ventilation channel and other structural components. The cooperation of the ventilation control unit, the intelligent detection processing unit, the standing person collection unit and the intelligent detection control unit can, on the one hand, ventilate the inside of the radiation shield 1 according to the periodic instructions of the intelligent detection processing unit during the application of the X-ray detection equipment, which can effectively avoid the accumulation of harmful gases. On the other hand, the ventilation effect can be intelligently coordinated and controlled according to the operating status of the X-ray detection machine 2 and the data of whether there is a person standing in the radiation shield 1, so as to further ensure the ventilation effect in the radiation shield 1, reduce the damage caused to the inspection personnel by harmful gases, and ensure the safety of the inspection personnel.

[0050] Figure 1 , Figure 2 , Figure 7 and Figure 8 It is shown that the output end of the intelligent detection processing unit is also connected to a delayed start unit, the input end of the delayed start unit is connected to the dual start instruction acquisition unit signal, and the output end of the delayed start unit is connected to the intelligent detection control unit signal. The setting of the delayed start unit can further ensure the safety of the inspection personnel in the process of using the X-ray detection machine 2, reserve sufficient time for the inspection personnel to evacuate the site, and promote the safety of the application of X-ray detection equipment.

[0051] Figure 1 - Figure 8 It is shown that during the application of the X-ray detection equipment, the inspector also inputs parameters about ventilation control and delayed start parameters into the detection parameter setting unit through the parameter button on the control box. The intelligent detection processing unit will transmit the data about delayed start received from the detection parameter setting unit to the delayed start unit. Subsequently, when the intelligent detection processing unit receives the dual start data, the dual start instruction acquisition unit will also transmit the dual start data to the delayed start unit. After receiving the dual start data, the delayed start unit will transmit the delayed data to the intelligent detection control unit. As a result, after receiving the detection data and control instructions transmitted by the intelligent detection processing unit, the intelligent detection control unit will delay the start-up time of the X-ray detection machine 2 according to the delayed data transmitted by the delayed start unit, which can effectively leave enough time for the inspectors to evacuate the site and further ensure the safety of the inspectors during work.

[0052] Then, after the intelligent detection and control unit controls the X-ray detection machine 2 to produce an inspection action according to the detection parameters and instructions transmitted by the intelligent detection processing unit, the intelligent detection processing unit will control the ventilation control unit to take effect, control the ventilation structure to produce action, and perform ventilation treatment on the harmful gases generated during the operation of the X-ray detection machine 2 to reduce the accumulation of harmful gases in the radiation shield 1, and the intelligent detection and control unit will also transmit its execution status data to the ventilation control unit. When the detection program is about to end, the ventilation control unit controls the ventilation structure to increase the ventilation power, further promoting the effect of ventilation, and effectively ensuring the safety of subsequent inspection personnel entering the radiation shield 1, and the intelligent detection and control unit controls After the X-ray detection machine 2 completes the detection task, and the intelligent detection processing unit transmits the detection data to the PC through the detection data output unit, the intelligent detection processing unit will control the ventilation control unit to close. Then, after the inspector enters the radiation protection cover 1 and stands on the weight sensing mat 4, the weight sensor in the weight sensing mat 4 transmits the weight data of the standing person to the standing person collection unit. While the standing person collection unit transmits the standing person data to the intelligent detection processing unit, the door lock unit and the safety protection unit, it also transmits the standing person data to the ventilation control unit, thereby activating the ventilation control unit to maintain the internal ventilation of the radiation protection cover 1 while the person is standing in it, further promoting the safety of the application of X-ray detection equipment.

[0053] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
