[0037] The engineering inspection device and method of the nuclear facility physical protection system in the present application are applied to the engineering inspection of the physical protection system of the nuclear facility after the construction of the physical protection system is completed.

[0038] <First Embodiment>

[0039] like Figure 1 to Figure 6 As shown, the first embodiment of the present application provides an engineering inspection device 100 (hereinafter, sometimes simply referred to as the engineering inspection device 100 ) for a nuclear facility physical protection system.

[0040] In the present application, the engineering inspection device 100 may be implemented in hardware, or in software modules running on one or more processors, or in a combination thereof. For example, the engineering inspection device 100 may be implemented in a combination of hardware and software by any suitable electronic device such as a desktop computer, a tablet computer, a smart phone, a server, etc. equipped with a processor.

[0041] The processor of the engineering inspection device 100 can execute the engineering inspection method described below.

[0042] The engineering inspection device 100 may further include a memory (not shown), a communication module (not shown), and the like.

[0043] The memory of the engineering inspection device 100 can store the various steps of the engineering inspection method described later, as well as data related to the engineering inspection. The memory can be, for example, a ROM (Read Only Memory image), a RAM (Random Access Memory), etc. The memory has a storage space for program codes for executing any step in the following engineering inspection method. When these program codes are read and executed by the processor, the following engineering inspection method is executed.

For example, the communication module can send the inspection result of the engineering inspection device 100 to a server, etc.

[0045] In addition, the engineering inspection device 100 may also include output units such as a display, a microphone, a speaker, etc., for displaying or broadcasting engineering inspection results, or issuing an alarm, etc.

[0046] In the following, the components of the engineering inspection device 100 are functional and conceptual components, and they may not necessarily be physically configured as shown in the figure. That is, the specific form of each device is not limited to the form shown in the figure, and all or part of them may be functionally or physically separated or combined in arbitrary units according to the processing load implemented by each device, the usage status, etc.

[0047] (Example 1)

[0048] Figure 1 1 is a block diagram schematically showing Example 1 of an engineering inspection device 100 for a nuclear facility physical protection system according to a first embodiment of the present application. Figure 1 As shown, the engineering inspection device 100 includes: a front-end equipment testing module 10 and a subsystem testing module 20 .

[0049] The front-end device testing module 10 tests the front-end device, and the front-end device at least includes a front-end detector.

[0050] Here, the front-end equipment refers to the equipment installed in the nuclear facility. The front-end equipment can collect data or provide signals, and is connected to the nuclear facility physical protection system and the engineering inspection device 100. In addition to the front-end detector, the front-end equipment can also include a camera for collecting video information, a lighting device for irradiating light, an X-ray machine for obtaining CT data, etc. Here, the front-end equipment selects the equipment included in the nuclear facility physical protection system, and is respectively connected to the subsystems corresponding to the functions in the integrated management platform of the nuclear facility physical protection system. In this embodiment, the front-end detector may include a microwave detector, a Doppler detector, an infrared detector, a tension detector, a vibration cable detector, a laser detector, etc., but is not limited thereto.

[0051] The subsystem test module 20 tests each subsystem of the nuclear facility physical protection system. The subsystem test module 20 can be applied to the integrated management platform of the nuclear facility physical protection system.

[0052] Here, the front-end device and the front-end device test module 10 can also be connected to the subsystem test module 20. The front-end device can send its collected data to the subsystem test module 20, and the front-end device test module 10 can also send its test results to the subsystem test module 20.

[0053] The subsystem test module 20 may have a plurality of subtest units corresponding to the subsystems of the nuclear facility physical protection system. The subsystems of the nuclear facility physical protection system at least include perimeter physical barriers, intrusion detection alarm systems, and video monitoring systems.

[0054] Correspondingly, if Figure 1 As shown, the subsystem test module 20 may specifically include: a perimeter physical barrier test unit 21 for testing the perimeter physical barrier, an intrusion detection alarm system test unit 22 for testing the intrusion detection alarm system, and a video surveillance system test unit 23.

[0055] The perimeter physical barrier testing unit 21 performs a test on the perimeter physical barrier, which is respectively arranged around the control area, the protection area, and the critical area divided according to the level of physical protection of the nuclear facility.

[0056] In the physical protection system of nuclear facilities, perimeter physical barriers refer to fences, walls or similar obstacles that can provide intrusion delay and assist in access control.

[0057] Since the principle of defense in depth is an important part of the basic principles of nuclear security and the foundation of nuclear security technology, in order to meet the principle of defense in depth, nuclear facilities need to set up multiple barriers for multiple protections. Therefore, control areas, protection areas, and key areas are set up for nuclear facilities.

[0058] In other words, the control area, protection area, and critical area can be divided according to the type and importance of nuclear materials and nuclear facilities. For example, the control area, protection area, and critical area can be divided according to the level of physical protection of nuclear facilities. Specifically, when a nuclear facility is a first-level physical protection nuclear facility, three perimeter physical barriers should be set up in the critical area, protection area, and control area; when a nuclear facility is a second-level physical protection nuclear facility, two perimeter physical barriers should be set up in the protection area and control area; when a nuclear facility is a third-level physical protection nuclear facility, one perimeter physical barrier should be set up in the control area.

[0059] Therefore, perimeter physical barriers are set up in the critical area, protection area and control area of ​​the nuclear facility, or in both the protection area and the control area, or only in the control area.

[0060] When the perimeter physical barrier includes a fence, the perimeter physical barrier testing unit 21 can test the fence height, the angle and height of the diagonal support, the side length of the fence mesh, etc.

[0061] Nuclear security also has the principle of balanced protection, and the entrance and exit barriers and walls (or fences) need to be able to achieve a balanced protection effect. Therefore, in this application, the perimeter physical barrier includes types such as entrance and exit barriers in addition to fences and walls. The perimeter physical barrier test unit 21 also tests the entrance and exit barriers. Specifically, the perimeter physical barrier test unit 21 can test the following test items: vehicle entrance and exit barrier requirements on the perimeter, perimeter maintenance entrance and exit barrier requirements, perimeter personnel entrance and exit barrier requirements, barrier requirements for the main entrance and exit on the perimeter, etc.

[0062] The intrusion detection alarm system test unit 22 may perform an intrusion detection alarm system test using front-end detectors disposed at specific selected points on the perimeter physical barrier.

[0063] In other words, a specific point can be selected on the physical barrier of the perimeter, and the front-end detector set at the specific point can be selected to perform the intrusion detection alarm system test. The specific point refers to the position of the front-end detector specially selected on the physical barrier of the perimeter. For example, the fences of the three physical barriers of the perimeter of the critical area, the protection area and the control area, the entrance and exit barriers and specific points near them. Since the intrusion detection alarm system test unit 22 uses the front-end detector set at the specific point on the physical barrier of the perimeter to perform the intrusion detection alarm system test, it can meet the principles of defense in depth and balanced protection of nuclear facilities while taking into account the accuracy and work efficiency of sampling statistics.

[0064] Specifically, the specific selection of points is equivalent to a sampling test. If there are too few specific selection points or the sampling locations are inappropriate, it may not be possible to accurately detect the situation where the intrusion detection alarm system does not meet the construction requirements, and the engineering inspection effect is not ideal; if there are too many specific selection points, the efficiency of engineering inspection may be reduced. Therefore, it is necessary to take into account the accuracy of sampling statistics and the efficiency of engineering inspection.

[0065] In this application, specific sites can be selected based on the following principles:

[0066] (1) Taking into account the principles of defense in depth and balanced protection of nuclear facilities, sampling is carried out according to the division of critical areas, protection areas and control areas; sampling can also be further carried out by considering the types of perimeter physical barriers.

[0067] (2) Sampling according to the type of front-end detectors. Specifically, different types of front-end detectors can be configured according to the area where the perimeter physical barrier is located, the type of the perimeter physical barrier, etc., and for each type of front-end detector, sampling can be performed according to existing sampling procedures such as GB / T 2828.1-2012. For example, if the number of front-end detectors of this type is less than 5, all of them are selected as specific points; if the number is greater than 5, sampling is performed again.

[0068] (3) Analyze the effectiveness of the physical protection system, calculate the effectiveness probability of various paths to enter the critical area, select the weak path of the physical protection system, and give priority to sampling from the front-end detectors on the weak path.

[0069] For example, the probability of effectiveness of a physical protection system can be calculated as follows.

[0070] The effectiveness of the physical protection system is measured by the probability P, which is determined by the interception probability P of the response force. I and the probability of winning P N decided.

[0071] That is, P is the interception probability P I and the probability of winning P N The product of:

[0072] P=P I ×P N (1)

[0073] Interception probability P I It is the product of the detection probability PA of the front detector arranged on the perimeter physical barrier and the timely response probability P(R|A):

[0074] P I =P(R|A)×PA (2)

[0075] The response probability P(R|A) is the probability that the response force will arrive at the deployment location before the intruder after receiving the alarm signal. I is the product of the detector's P(R|A), P(A) and the probability that all detectors before this detector cannot detect the intrusion. If there is no other detector before this detector, then P I =P(R|A)×P(A). Then the cumulative interception probability on the intrusion path from the starting point to the end point is the sum of the interception probabilities of all detectors:

[0076]

[0077] (4) Winning probability P N The calculation method of is as follows.

[0078]

[0079] Among them, x is the number of combat units of the reaction force at time t; y is the number of combat units of the invading enemy at time t; α is the average combat power of each combat unit of the reaction force; β is the average combat power of each combat unit of the invading enemy. The deterrence probability is calculated based on the design basis threat and the weapon configuration of the armed police force. The path with the smallest effectiveness probability P of the above-mentioned physical protection system is determined as the weak path, and the front-end detector of the weak path is selected first.

[0080] The above-mentioned calculation method of validity probability and weak path may also be performed by any existing method.

[0081] The following is a specific description of the combined application of the above principles (1) and (2).

[0082] As an example, when a nuclear facility is in the second-level physical protection, two perimeter physical barriers are set up, namely the protection zone and the control zone. At this time, microwave detectors, Doppler detectors, infrared detectors, and vibration cable detectors can be set up in the protection zone, and infrared detectors, the tension detectors, and laser detectors can be set up in the critical zone.

[0083] In order to strengthen the protection of the protected area, a double-layer fence can be set up in the protected area. In this case, the protected area includes a double layer, an isolation zone between the double layers of fences, and an entrance and exit barrier, while the critical area includes a single layer of fence and an entrance and exit barrier. In this case, the above-mentioned specific selected points are located on the isolation zone of the protected area, and the fences and entrance and exit barriers of the protected area and the critical area. Specifically, microwave detectors and Doppler detectors can be set on the isolation zone of the protected area, while vibration cable detectors can be set on the fence of the protected area, tension detectors can be set on the fence of the critical area, infrared detectors can be set on the upper space of the entrance and exit barriers of the driveway gates or revolving doors on the fences of the protected area and the critical area, and laser detectors can be set on the entrance and exit barriers of the driveway gates and other entrances and exits of the critical area.

[0084] The above detectors can be used in the intrusion detection alarm system test unit 22 to test the perimeter intrusion alarm project.

[0085] When the intrusion detection alarm system test unit 22 tests the perimeter intrusion alarm project, as an example, the intrusion detection alarm system test unit 22 can use the microwave detector and Doppler detector installed on the isolation belt of the protection zone to detect and alarm the intruders who break into the protection zone; use the vibration cable detector installed on the fence of the protection zone to detect the illegal behavior of the intruders climbing over or cutting the fence net; use the tension detector installed on the fence of the critical area to detect the deformation of the tension sensing line, so as to alarm the compression, climbing or cutting of the fence of the critical area; use the infrared detector to detect the intruders, and the infrared detector is installed in the upper space of the driveway gate or revolving door on the fence of the protection zone and the critical area; use the laser detector installed on the driveway gate of the critical area to supplement the blind spot of the infrared detector.

[0086] By selecting front-end detectors at such specific points and making comprehensive use of the characteristics of various detectors, we can rationally collect targeted and calibrated data on different safety requirement areas and different perimeter physical barrier types of nuclear facilities, thereby achieving in-depth defense and balanced protection while further improving the targeting and engineering inspection efficiency.

[0087] In addition, the intrusion detection alarm system test unit 22 can also test the following test items: detection function, anti-dismantling function, anti-destruction and fault identification function, function setting, operation function, indication function, notification function, transmission function, recording function, response time, alarm information analysis function, entrance and exit intrusion alarm function on the perimeter, security control center intrusion alarm function, important parts intrusion alarm requirements, and emergency alarm device equipment.

[0088] In addition, if Figure 2 As shown, since the intrusion detection alarm system test unit 22 uses the front-end detectors on the specific selected points of the perimeter physical barrier respectively set in the control area, the protection area, and the key area to perform the test, the front-end detectors on the perimeter physical barrier can be started at the same time when the perimeter physical barrier is tested, so that the perimeter physical barrier test and the intrusion detection alarm system test can be performed at the same time. Therefore, compared with the situation where the perimeter physical barrier test and the intrusion detection alarm system test are performed separately in sequence, the test time can be reduced and the efficiency of engineering inspection and testing can be improved.

[0089] The video surveillance system test unit 23 can use the camera in the front-end device to test the video surveillance system. Here, the camera can include: a fixed IP camera, a high-definition PTZ camera, etc. Here, the front-end device test module 10 can test the camera in the front-end device test before starting the subsystem test.

[0090] The video monitoring system of the physical protection system may be connected to cameras at various points inside and outside the nuclear facility to obtain comprehensive monitoring data. However, the video monitoring system test unit 23 preferably selects cameras near the above-mentioned specific points on the perimeter physical barrier for testing.

[0091] The so-called vicinity of a specific selected point means that the distance to the specific selected point is within a predetermined range.

[0092] The video surveillance system test can test at least one of the following test items: video acquisition function, transmission, switching scheduling function, remote control function, video display function, storage / playback / retrieval function, video analysis function, system management function, power failure protection, video surveillance equipment installation, perimeter video surveillance, perimeter entrance and exit video surveillance, security control center video surveillance, important parts video surveillance, corridor video surveillance.

[0093] As an example, Figure 4 As shown, a fixed IP camera can be set between the control area and the protection area, and a high-definition PTZ camera can be set between the protection area and the key area. Thus, higher quality surveillance video can be provided for the key area.

[0094] The video surveillance system test unit 23 may also select a camera near the above-mentioned specific point to review the alarm content of the intrusion detection alarm system test unit 22 once an alarm is triggered in the intrusion detection alarm system test unit 22 .

[0095] Specifically, after the alarm is triggered, a camera near a specific point is selected, and the scene image captured by the camera is used to determine whether the alarm content of the intrusion detection alarm system test unit 22 is accurate.

[0096] The above-mentioned review can be performed automatically through image recognition or the like, or the content of the corresponding camera can be highlighted, for example, displayed as a pop-up on the display of the engineering inspection device 100, so that the tester can manually review it.

[0097] Since the cameras selected in the video surveillance system test are near specific selected points on the perimeter physical barrier, the intrusion detection alarm system test can be reviewed through these cameras.

[0098] Through the above review, it is possible to determine whether the alarm function of the intrusion detection alarm system test unit 22 is accurate, whether the image display function of the video surveillance system test unit 23 is normal, and improve the reliability and accuracy of engineering inspection.

[0099] In addition, since the alarm function of the intrusion detection alarm system test unit 22 is triggered, the video surveillance system test unit 23 will conduct a review, so the video surveillance system test can be automatically entered after the intrusion detection alarm system test. That is, the intrusion detection alarm system test unit 22 and the video surveillance system test unit 23 can be linked. In this way, the perimeter physical barrier test, the intrusion detection alarm system test, and the video surveillance system test can be performed at one time, which can reduce the operating burden, reduce the inspection steps, and improve the test efficiency of the engineering inspection.

[0100] (Example 2)

[0101] Figure 3 1 is a block diagram showing Example 2 of the engineering inspection device 100 according to the first embodiment of the present application. The difference between Example 2 and Example 1 is that the subsystem of the physical protection system further includes a lighting system, and correspondingly, the subsystem test module 20 further includes a lighting system test unit 24.

[0102] The lighting system test unit 24 tests the lighting system, that is, performs a lighting system test.

[0103] The lighting system test can test at least one of the following test items: the installation position and light direction of perimeter lighting poles, the night ground illumination around the control area, the night ground illumination around the protection area, the night ground illumination around the critical area, the night ground illumination at the critical indoor parts, the working surface illumination of the main entrance and exit of the control area, the working surface illumination of the main entrance and exit of the protection area, the working surface illumination of the main entrance and exit of the critical area, the working surface illumination of the control center, uninterrupted lighting, and the control method of turning on and off the lighting.

[0104] In order to test the above test items, the lighting system test unit 24 selects lighting points inside and outside the nuclear facility, and uses the lighting facilities at the lighting points to perform the test. That is, lighting point selection means that when a nuclear facility is equipped with multiple lighting facilities, a part of them is selected for testing, so as to determine whether the lighting system in the nuclear facility physical protection system is normal, which is also equivalent to a sampling of lighting facilities. Among them, the lighting facilities can be, for example, lighting lamps. The lighting facilities can also be set on the perimeter physical barrier.

[0105] Here, a lighting device such as a lighting lamp may be included in the front-end device, and the front-end device test module 10 may test the lighting lamp in the front-end device test before starting the subsystem test.

[0106] In the case where the subsystem test module 20 includes a lighting system test unit 24, when the video surveillance system test unit 23 performs testing at night, a part or all of the lighting points selected by the lighting system test unit 24 as described above are selected, and the video surveillance system test is performed using a camera configured nearby.

[0107] Thus, the problem that the camera's shooting effect is not good and the video surveillance system test results are inaccurate or unusable when testing at night can be solved. Therefore, by using the linkage of the lighting system test unit 24 and the video surveillance system test unit 23, it is possible to reduce invalid or poorly effective video surveillance system tests and improve the efficiency and accuracy of engineering inspections.

[0108] In addition, the specific selected point of the intrusion detection alarm system test unit 22 can also be located near the lighting selected point performed by the lighting system test unit 24. At this time, since the specific selected point of the front-end detector of the intrusion detection alarm system test unit 22, the camera near the specific selected point selected by the video monitoring system test unit 23, and the lighting selected point of the lighting system test unit 24 are all located in a similar position, the video monitoring system test unit 23 can simultaneously realize the review of the intrusion detection alarm system test unit 22 and the nighttime lighting of the camera, thereby improving the accuracy of the nighttime review. That is, the linkage of the four units of the perimeter physical barrier test unit 21, the intrusion detection alarm system test unit 22, the video monitoring system test unit 23, and the lighting system test unit 24 can be realized.

[0109] (Example 3)

The difference between Example 3 and Example 2 is that the subsystem test module 20 includes at least one of the following subsystem test units in addition to the perimeter physical barrier test unit 21, the intrusion detection alarm system test unit 22, the video surveillance system test unit 23, and the lighting system test unit 24.

Specifically, the power supply system test unit 26 can test at least one of the test items such as the backup power supply, the main and backup power supply conversion, and the distribution box.

[0113] The integrated management system test unit 27 tests the integrated management system of the nuclear facility physical protection system. Specifically, the integrated management system test unit 27 can test at least one of the following test items: integrated management, information management, user management, equipment management, linkage control, log management, statistical analysis, system time calibration, plan management, human-computer interaction, command and dispatch, and emergency command center equipment access.

[0116] The line transmission system test unit 30 tests the line transmission system of the nuclear facility physical protection system. Specifically, the line transmission system test unit 30 can test test items such as cable laying. For example, when the cable route from the high-risk area passes through the low-risk area, necessary protective measures should be taken; the cable connection points and terminals should be uniformly numbered and permanently marked, and labels should be set at both ends of the cable, inspection holes, etc.

[0117] The security communication system test unit 31 tests the security communication system of the nuclear facility physical protection system.

Specifically, the explosion-proof safety inspection system test unit 35 may test at least one of the test items such as safety inspection settings, equipment requirements, X-ray dose, information storage time, safety inspection area settings, safety inspection area video surveillance requirements, and safety inspection equipment installation.

[0122] As described above, in this embodiment, the subsystem test module 20 has sub-test units corresponding to the various subsystems of the nuclear facility physical protection system, so that targeted engineering inspections can be performed on the various subsystems of the nuclear facility physical protection system. It has strong operability and can obtain comprehensive and complete engineering inspection results.

[0123] At this time, the front-end equipment test module 10 can also test the front-end equipment including the front-end detector, camera, lighting equipment, X-ray machine, etc. Thus, the engineering inspection results of the front-end detector, camera, lighting equipment, X-ray machine, etc. and the engineering inspection results of each subsystem can be obtained respectively, so as to avoid misjudgment of the nuclear facility physical protection system due to the failure of the front-end equipment.

[0124] <Second Embodiment>

[0125] As a second embodiment, an engineering inspection method for a nuclear facility physical protection system (hereinafter, sometimes simply referred to as an engineering inspection method) is provided.

[0126] (Example 1)

[0127] like Figure 5 As shown, in Example 1 of the second embodiment, the method includes steps S10 and S20.

[0128] In step S10 , the front-end device testing module 10 tests the front-end device including the front-end detector.

[0129] In step S20, the subsystem testing module 20 tests each subsystem of the nuclear facility physical protection system.

[0130] Preferably, step S10 is performed before step S20. Thus, before starting the subsystem test, the front-end device is first checked to see if it is in good condition, thereby avoiding deviations in the engineering inspection results of each subsystem due to a failure of the front-end device.

[0131] Specifically, step S20 may include step S21, step S22 and step S23.

[0132] In step S21, the perimeter physical barrier test unit 21 selects points around the control area, protection area, and critical area of ​​the nuclear facility to set up front-end detectors, and performs a perimeter physical barrier test.

[0133] In step S22, the intrusion detection alarm system test unit 22 uses the front-end detector to perform an intrusion detection alarm system test.

[0134] Among them, step S21 and step S22 are executed simultaneously, and the front-end detector is shared by steps S21 and S22.

[0135] In other words, the same detection data of the front-end detector can be acquired in step S10 and transmitted to steps S21 and S22 at the same time, and the processing of steps S21 and S22 can be started at the same time.

[0136] By executing step S21 and step S22 simultaneously, the test time can be reduced and the efficiency of engineering inspection and testing can be improved.

[0137] In step S23, the video surveillance system testing unit 23 tests the video surveillance system.

[0138] There may be a determination step S41 between step S22 and step S23.

[0139] In step S41, it can be determined whether an alarm is triggered in step S22. If so, the process automatically enters step S23, in which the camera of the video surveillance system test unit 23 is automatically started to review the result of step S22.

[0140] In other words, in this embodiment, it is determined whether an alarm is triggered during the intrusion detection alarm system test, and if so, the video surveillance system test is automatically started.

[0141] Among them, in step S23, it is preferred to select a camera near the point selected in step S21 for testing.

[0142] By processing step S41, step S22 and step S23 can be linked together, so that the perimeter physical barrier test, intrusion detection alarm system test, and video surveillance system test can be performed at one time, which can reduce the operating burden, reduce the inspection steps, and improve the test efficiency of engineering inspection. By using the camera near the selected point in step S21 in step S23, the result of step S22 can be easily compounded through step S23.

[0143] Of course, in Embodiment 2, step S41 may not be included, but step S23 may be performed before or after step S21 or step S22, or step S23 may be performed simultaneously with steps S21 and S22.

[0144] The specific details and effects of Example 1 of the engineering inspection method provided in the second embodiment can refer to the specific contents of Example 1 of the engineering inspection device provided in the first embodiment.

[0145] (Example 2)

[0146] like Figure 6 As shown, in Example 2 of the second embodiment, compared with Example 1 of the second embodiment, step S20 of the engineering inspection method further includes step S24.

[0147] In step S24, the lighting system testing unit 24 tests the lighting system using the lighting facilities selected by the selection point.

[0148] In the case where the subsystem test module 20 includes the lighting system test unit 24, the above-mentioned step S23 may include steps S231 and S232.

[0149] In step S231, it is determined whether the video surveillance system test unit 23 performs the test at night. If so, the process proceeds to step S232.

[0150] In step S232, a part or all of the lighting points selected by the lighting system testing unit 24 are selected to perform video surveillance system testing.

[0151] In addition, step S23 may also include step S233.

[0152] When it is determined in step S231 that the video surveillance system test unit 23 is not testing at night, the process proceeds to step S233.

[0153] In step S233, a normal video monitoring system test is performed. The normal video monitoring system test is the same test as when the determination in S231 is not performed, and any camera can be selected to perform the test.

[0154] By executing steps S231 and S232, the problem that the video surveillance system test results are inaccurate or unusable due to poor camera shooting effects during nighttime testing can be solved. Therefore, by using steps S231 and S232, the video surveillance system test step S23 and the lighting system test step S24 can be linked, which can reduce invalid or poorly effective video surveillance system tests and improve the efficiency and accuracy of engineering inspections.

[0155] The specific details and effects of Example 2 of the engineering inspection method provided in the second embodiment may refer to the specific contents of Example 2 of the engineering inspection device of the first embodiment.

[0156] (Example 3)

[0157] In Example 3 of the second embodiment, compared with Example 2 of the second embodiment, step S20 of the engineering inspection method further includes at least one of the following steps. Figure 7 The example in which all the following steps are included is shown, that is, step S20 includes steps S21 to S35.

[0158] In step S25, the access control system testing unit 25 tests the access control system of the nuclear facility physical protection system.

[0159] In step S26 , the power supply system testing unit 26 tests the power supply system of the nuclear facility physical protection system.

[0160] In step S27, the integrated management system testing unit 27 tests the integrated management system of the nuclear facility physical protection system.

[0161] In step S28, the patrol system testing unit 28 tests the patrol system of the nuclear facility physical protection system.

[0162] In step S29, the security control center testing unit 29 tests the security control center of the nuclear facility physical protection system.

[0163] In step S30 , the line transmission system testing unit 30 tests the line transmission system of the nuclear facility physical protection system.

[0164] In step S31 , the security communication system testing unit 31 tests the security communication system of the nuclear facility physical protection system.

[0165] In step S32, the safety and network security system testing unit 32 tests the safety and network security system of the nuclear facility physical protection system.

[0166] In step S33, the electromagnetic compatibility system testing unit 33 tests the electromagnetic compatibility system of the nuclear facility physical protection system.

[0167] In step S34, the lightning protection and grounding system testing unit 34 tests the lightning protection and grounding system.

[0168] In step S35 , the explosion-proof safety inspection system testing unit 35 tests the explosion-proof safety inspection system of the nuclear facility physical protection system.

[0169] In this embodiment, targeted engineering inspections can be performed on various subsystems of the nuclear facility physical protection system, and the operability is strong, so that comprehensive and complete engineering inspection results can be obtained.

[0170] The operations of the above-mentioned steps S25 to S35 are relatively independent, and therefore, they can be executed in parallel or in series, and there is no special limitation on this. In addition, S21 to S24 can also be executed in parallel independently, and therefore, Figure 7 Only one example is shown in which all steps S21 to S35 are executed in parallel.

[0171] However, Examples 1 to 3 and Example 4 of the second embodiment described above may be combined.

[0172] In step S10, the front-end device testing module 10 can also test the front-end devices such as the front-end detector, camera, lighting equipment, X-ray machine, etc. separately, and send the data generated in the test to the corresponding subsystem testing unit in the subsystem testing module 20, and enter the corresponding subsystem testing steps in steps S21 to S35.

[0173] The specific details and effects of Example 3 of the engineering inspection method provided in the second embodiment may refer to the specific contents of Example 3 of the engineering inspection device provided in the first embodiment.

[0174] Although embodiments of the engineering inspection device and method for the physical protection system of nuclear facilities are provided above, the present application may also be implemented in the form of a storage medium storing a program for executing each step of the above-mentioned engineering inspection method.

[0175] Although the implementation modes and specific examples of the present invention are described above in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the claims.
