(example 1)

Fig. 1 is a block diagram schematically showing example 1 of an engineering verification device 100 of a nuclear facility physical protection system according to a first embodiment of the present invention. As shown in fig. 1, the engineering verification apparatus 100 includes: a front-end device test module 10 and a subsystem test module 20.

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

Here, the front-end device refers to a device installed in a nuclear facility. The front-end equipment can collect data or provide signals and is connected with the nuclear facility physical protection system and the engineering inspection device 100. In addition to the front-end detector, the front-end device may include a camera for collecting video information, an illumination device for illuminating light, an X-ray machine for obtaining CT data, and the like. The front-end equipment selects the equipment contained in the nuclear facility physical protection system and is respectively connected with the subsystems corresponding to the functions in the integrated management platform of the nuclear facility physical protection system. In the present embodiment, the front end detector may include a microwave detector, a doppler detector, an infrared detector, a tension detector, a vibrating cable detector, a laser detector, and the like, but is not limited thereto.

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

Here, the front-end device and the front-end device test module 10 may be connected to the subsystem test module 20. The front-end device may send the data collected by the front-end device to the subsystem test module 20, and the front-end device test module 10 may also send the test result to the subsystem test module 20.

The subsystem test module 20 may include a plurality of sub-test units corresponding to the subsystems of the nuclear facility physical protection system. The subsystem of the nuclear facility physical protection system at least comprises a perimeter entity barrier, an intrusion detection alarm system and a video monitoring system.

Correspondingly, as shown in fig. 1, the subsystem test module 20 may specifically include: a perimeter entity barrier testing unit 21 for testing the perimeter entity barrier, an intrusion detection alarm system testing unit 22 for testing the intrusion detection alarm system, and a video monitoring system testing unit 23.

The perimeter entity barrier test unit 21 performs a test of a perimeter entity barrier, and the perimeter entity barrier is respectively disposed around a control area, a protection area, and an essential area that are divided according to the level of physical protection of the nuclear facility.

In the physical protection system of the nuclear facility, the perimeter physical barrier means: fences, walls or similar barriers that can provide intrusion delay and assist in access control.

Since the defense-in-depth principle is an important component of the basic principle of nuclear security and is also the basis of the nuclear security technology, in order to meet the defense-in-depth principle, a plurality of barriers are required to be arranged on the nuclear facility for multiple protection, and therefore, a control area, a protection area and a critical area are arranged on the nuclear facility.

In other words, the control zone, the protection zone, and the critical zone may be divided according to the type and importance of the nuclear material and the nuclear facility. For example, the control zone, the protection zone, and the critical zone may be divided according to the level of physical protection of the nuclear facility. Specifically, when the nuclear facility is a first-level physical protection nuclear facility, three perimeter solid barriers of a key area, a protection area and a control area are set; when the nuclear facility is a secondary physical protection nuclear facility, two perimeter entity barriers of a protection area and a control area are required to be arranged; when the nuclear facility is a three-level physical protection nuclear facility, a control area and a perimeter entity barrier are arranged.

Therefore, the perimeter solid barrier is provided in all three of the critical zone, the protected zone, and the control zone of the nuclear facility, or in both the protected zone and the control zone, or in only the control zone.

When the perimeter solid barrier includes a fence, the perimeter solid barrier testing unit 21 can test fence height, angle and height of the diagonal brace, mesh side length of the fence, and the like.

The nuclear security protection also has a balanced protection principle, and the entrance barrier and the enclosure (or the fence) need to achieve a balanced protection effect. Thus, in the present application, a perimeter physical barrier includes types such as an entrance barrier in addition to types such as fences, and the like. The perimeter physical barrier test unit 21 also tests the entrance and exit barrier. Specifically, the perimeter entity barrier test unit 21 may test the following test items: vehicle doorway barrier requirements at the perimeter, perimeter service doorway barrier requirements, perimeter personnel doorway barrier requirements, barrier requirements at the main doorway at the perimeter, and the like.

The intrusion detection alarm system test unit 22 may perform intrusion detection alarm system tests using front-end detectors placed at specific selected points on the perimeter physical barrier.

In other words, a specific point selection can be performed on the perimeter physical barrier, and the front-end detector arranged at the specific point selection is selected to perform the intrusion detection alarm system test. The specific setpoint refers to a specifically selected position of the front-end detector on the perimeter physical barrier. For example, fences of three perimeter physical barriers of a critical area, a protection area and a control area, entrance and exit barriers and specific points near the entrance and exit barriers, and the like. Since the intrusion detection alarm system test unit 22 executes intrusion detection alarm system test by using the front-end detector disposed at a specific selected point on the perimeter physical barrier, the principles of depth defense and balance protection of the nuclear facility can be satisfied while taking into account the accuracy of the sampling statistics and the working efficiency.

Specifically, a particular setpoint is equivalent to performing a sampling test. If the specific point selection position is too few or the sampling position is not appropriate, the condition that the intrusion detection alarm system does not meet the construction requirements can not be accurately detected, and the engineering inspection effect is not ideal; if the specific point selection positions are too many, the work efficiency of engineering inspection can be reduced, and therefore, the accuracy of sampling statistics and the work efficiency of engineering inspection need to be considered at the same time.

In the present application, the specific selection point can be made based on the following principle:

(1) Sampling according to the division of the vital area, the protection area and the control area by considering the principles of depth defense and balanced protection of the nuclear facility; the sampling may also be performed further taking into account the type of perimeter entity barrier.

(2) Sampling is performed according to the type of the front-end detector. Specifically, different types of front-end detectors can be configured according to the area where the perimeter entity barrier is located, the type of the perimeter entity barrier, and the like, and for each type of front-end detector, sampling is performed according to an existing sampling program such as GB/T2828.1-2012. For example, if the number of front-end detectors of the type is less than 5, all the front-end detectors are taken as specific selection points; if the number is more than 5, the pumping is performed again.

(3) And analyzing the effectiveness of the material object protection system, calculating the effectiveness probability of various paths attacking the critical area, selecting a weak path of the material object protection system, and preferentially sampling from a front-end detector on the weak path.

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

The effectiveness of the physical protection system is measured by the probability P, which is the interception probability of the response force

And probability of winning

And (6) determining.

I.e., P is the interception probability

And probability of winning

The product of (a):

（1）

probability of interception

Probability of detection PA and probability of timely response for front-end detectors arranged on a perimeter physical barrier

The product of (a):

（2）

probability of response

The probability of the intruder reaching the deployment site is preceded after the response force receives the alarm signal. Probability of interception per detector P _I Of the detector

P (A) and the probability that all detectors before the detector will not detect the intrusion, if the detector has no other detectors before it

. Then the cumulative interception probability on the intrusion path from the start point to the end point is the sum of all detector interception probabilities:

（3）

(4) Probability of winning

The following method is used for the calculation of (c).

（4）

Wherein x is the number of combat units of the reaction force at time t; y is the number of fighting units of the invading enemy at the moment t; alpha is the average fighting power of each fighting unit of the reaction force; beta is the average fighting capacity of each fighting unit of the invading enemy, and the stopping probability is calculated according to the design benchmark threat and the weapon configuration of the armed police forces. And determining the path with the small validity probability P of the real object protection system as a weak path, and preferentially selecting points of a front-end detector of the weak path.

The calculation method of the validity probability and the weak path described above may be any conventional method.

Hereinafter, the general application of the above principles (1) and (2) will be specifically described.

As one example, when the nuclear facility is secondary physical protection, two perimeter physical barriers are provided for the protection zone and the control zone. At this time, the microwave detector, the doppler detector, the infrared detector, and the vibration cable detector may be disposed in the protection area, and the infrared detector, the tension detector, and the laser detector may be disposed in the critical area.

In order to enhance the protection of the protection area, the protection area may be provided with double-layer fences, where the protection area includes double layers, an isolation strip between the double layers of fences, and an entrance barrier, and the critical area includes a layer of fence and an entrance barrier. In this case, the specific selected points are located on the isolation zone of the protected area, the enclosure of the protected area and the critical area, and the entrance and exit barrier. Specifically, the microwave detector and the doppler detector may be disposed on an isolation zone of the protection area, the vibrating cable detector may be disposed on a fence of the protection area, the tension detector may be disposed on a fence of the critical area, the infrared detector may be disposed in an upper space of an entrance/exit barrier of an entrance/exit such as a doorway or a revolving door on the fence of the protection area and the critical area, and the laser detector may be disposed on an entrance/exit barrier of an entrance/exit such as a doorway of the critical area.

The detector can be used for the intrusion detection alarm system testing unit 22 to test the perimeter intrusion alarm project.

When the intrusion detection alarm system testing unit 22 tests the perimeter intrusion alarm project, as an example, the intrusion detection alarm system testing unit 22 may utilize a microwave detector and a doppler detector which are arranged on an isolation zone of the protection zone to detect and alarm intruders intruding into the protection zone; detecting the illegal crossing or cutting of the fence net by an intruder by using a vibrating cable detector arranged on the fence of the protection area; detecting the deformation of the tension induction line by using a tension detector arranged on the fence of the key area, thereby alarming the oppression, climbing or cutting of the fence of the key area; detecting intruders by using an infrared detector which is arranged in the upper space of a lane door or a revolving door on the fences of the protection area and the critical area; the laser detector arranged at the lane door of the critical area is used for supplementing the blind area of the infrared detector.

By selecting the front-end detector at the specific selection point, the characteristics of various detectors are comprehensively utilized, and data of different safety requirement areas, different perimeter entity barrier types and pertinence correction of the nuclear facility are reasonably acquired, so that the deep defense and the balanced protection can be realized, and the pertinence and the engineering inspection efficiency are further improved.

In addition, the intrusion detection alarm system test unit 22 may also perform the following tests: the system comprises a detection function, an anti-dismantling function, a damage prevention and fault identification function, a function setting function, an operation function, an indication function, an announcement function, a transmission function, a recording function, response time, an alarm information analysis function, a perimeter entrance and exit intrusion alarm function, a security control center intrusion alarm function, an important part intrusion alarm requirement and an emergency alarm device.

In addition, as shown in fig. 2, since the intrusion detection alarm system test unit 22 performs the test by using the front-end detectors respectively disposed at specific selected points of the perimeter entity barriers of the control area, the protection area, and the critical area, the front-end detectors on the perimeter entity barriers can be simultaneously activated when the test is performed on the perimeter entity barriers, so that the perimeter entity barrier test and the intrusion detection alarm system test can be simultaneously performed. Therefore, compared with the condition that the perimeter entity barrier test and the intrusion detection alarm system test are sequentially and respectively carried out, the testing time can be reduced, and the engineering inspection testing efficiency is improved.

The video monitoring system test unit 23 may perform a test of the video monitoring system using a camera in the front-end equipment. Here, the camera may include: fixed IP cameras, high definition pan-tilt cameras, and the like. Here, the front-end device testing module 10 may test the camera in the front-end device test before starting the subsystem test.

The video monitoring system of the physical protection system may be connected to cameras at various points throughout the nuclear facility, to obtain comprehensive monitoring data. However, the video surveillance system test unit 23 preferably selects cameras near the specific selection points described above on the perimeter physical barrier to be tested.

The vicinity of the specific selected point means that the distance from the specific selected point is within a predetermined range.

The video surveillance system test may test at least one of the following test items: the system comprises a video acquisition function, a transmission function, a switching and scheduling function, a remote control function, a video display function, a storage/playback/retrieval function, a video analysis function, a system management function, power-off protection, video monitoring and control of equipment installation, perimeter video monitoring, perimeter entrance and exit video monitoring, video monitoring of a security control center, video monitoring of important parts and corridor video monitoring.

As an example, as shown in fig. 4, a fixed IP camera may be provided between the control area and the protection area, and a high-definition pan-tilt camera may be provided between the protection area and the critical area. Thus, higher quality surveillance video is provided for the critical area.

The video monitoring system testing unit 23 may also select the cameras near the specific selected points to review the alarm content of the intrusion detection alarm system testing unit 22 once an alarm is triggered in the intrusion detection alarm system testing unit 22.

Specifically, after the alarm is triggered, a camera near a specific selected point is selected, and whether the alarm content of the intrusion detection alarm system test unit 22 is accurate is determined according to a field image shot by the camera.

The review may be performed automatically by image recognition or the like, or the contents of the corresponding camera may be highlighted, for example, pop-up displayed on the display of the engineering inspection apparatus 100, so that the tester may manually perform the review.

Since the selected cameras in the video monitoring system test are near the specific selected points on the perimeter entity barrier, the rechecking of the intrusion detection alarm system test can be realized through the cameras.

Through the rechecking, whether the alarm function of the intrusion detection alarm system test unit 22 is accurate and the image display function of the video monitoring system test unit 23 is normal can be judged, and the reliability and the accuracy of engineering inspection are improved.

In addition, after the alarm function of the intrusion detection alarm system test unit 22 is triggered, the video monitoring system test unit 23 checks the alarm function again, so that the video monitoring system test can be automatically started 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 may be linked. Therefore, the perimeter entity barrier test, the intrusion detection alarm system test and the video monitoring system test can be performed at one time, the operation burden can be reduced, the inspection steps are reduced, and the test efficiency of engineering inspection is improved.

(example 2)

Fig. 3 is a block diagram showing example 2 of the engineering verification apparatus 100 according to the first embodiment of the present application. The embodiment 2 is different from the embodiment 1 in that the subsystem of the physical protection system further includes an illumination system, and correspondingly, the subsystem test module 20 further includes an illumination system test unit 24.

The lighting system testing unit 24 tests the lighting system, i.e. performs a lighting system test.

The lighting system test may test at least one of the following test items: the peripheral lighting lamp post installation position and lamplight orientation, the control area peripheral night ground illumination, the protection area peripheral night ground illumination, the essential area peripheral night ground illumination, the indoor essential part ground illumination, the control area main access working face illumination, the protection area main access working face illumination, the essential area main access working face illumination, the control center working face illumination, the uninterrupted lighting and the lighting lamp switching control mode.

The lighting system test unit 24 performs lighting setpoints inside and outside the nuclear facility in order to test the above test items, and tests are performed using the lighting facilities at the lighting setpoints. That is, the lighting selection is a test performed by selecting a part of a plurality of lighting facilities provided in the nuclear facility, and determining whether or not the lighting system in the nuclear facility entity protection system is normal, that is, a sampling of the lighting facilities. Wherein the lighting facility may for example be a lighting lamp. Lighting fixtures may also be disposed on the perimeter physical barrier.

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

When the subsystem test module 20 includes the lighting system test unit 24, when the video surveillance system test unit 23 performs a test at night, a part or all of the lighting points selected by the lighting system test unit 24 as described above are selected, and a video surveillance system test is performed by using cameras disposed in the vicinity thereof.

Therefore, the problem that when the test is carried out at night, the shooting effect of the camera is poor, and the test result of the video monitoring system is inaccurate or cannot be used is solved.

In addition, the specific point selection of the intrusion detection alarm system test unit 22 may also be located near the lighting point selection performed by the lighting system test unit 24, and at this time, since the specific point selection of the front-end detector performed by the intrusion detection alarm system test unit 22, the camera near the specific point selection selected by the video monitoring system test unit 23, and the lighting point selection of the lighting system test unit 24 are all located at similar positions, the rechecking of the intrusion detection alarm system test unit 22 and the night lighting of the camera performed by the video monitoring system test unit 23 can be simultaneously achieved, so that the accuracy of the night rechecking can be improved. That is, the four units of the perimeter entity 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 linked.

< second embodiment >

As a second embodiment, there is provided a method of engineering inspection of a nuclear facility entity protection system (hereinafter, may be simply referred to as an engineering inspection method).

(example 1)

As shown in fig. 5, in example 1 of the second embodiment, the method includes a step S10 and a step S20.

In step S10, the front-end device testing module 10 tests a front-end device including a front-end probe.

In step S20, the subsystem test module 20 tests each subsystem of the physical protection system for nuclear facilities.

Preferably, step S10 is performed before step S20. Therefore, before the subsystem test is started, whether the front-end equipment is good or not is checked, so that the condition that engineering check results of the subsystems deviate due to the fault of the front-end equipment can be avoided.

Specifically, the S20 step may include S21 step, S22 step, and S23 step.

In step S21, the perimeter entity barrier test unit 21 performs point selection and front-end detector setting on the periphery of the control area, the protection area, and the critical area of the nuclear facility, respectively, and performs the perimeter entity barrier test.

In step S22, the intrusion detection alarm system test unit 22 performs intrusion detection alarm system test using the front-end detector.

Wherein, the step S21 and the step S22 are executed simultaneously, and the front end detector is shared in the step S21 and the step S22.

In other words, the detection data of the same front-end probe may be acquired in step S10 and transferred to steps S21 and S22 at the same time, and the processing of steps S21 and S22 may be started at the same time.

By executing the step S21 and the step S22 simultaneously, the testing time can be reduced, and the engineering inspection testing efficiency can be improved.

In step S23, the video monitoring system test unit 23 tests the video monitoring system.

There may also be a decision step S41 between the steps S22 and S23.

In step S41, it may be determined whether an alarm is triggered in step S22, if yes, the process automatically proceeds to step S23, and in step S23, the camera of the video monitoring system test unit 23 is automatically started to review the result of step S22.

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 monitoring system test is automatically started.

In step S23, it is preferable to select a camera near the selected point in step S21 and perform the test.

By performing the processing of the step S41, the step S22 and the step S23 can be linked, so that the perimeter entity barrier test, the intrusion detection alarm system test, and the video monitoring system test can be performed at one time, the operation load can be reduced, the inspection steps can be reduced, and the test efficiency of the engineering inspection can be improved. By using a camera near the selected point in the step S21 in the step S23, it is possible to easily combine the results of the step S22 by the step S23.

Of course, in embodiment 2, the step S23 may be executed before or after the step S21 or the step S22, or the step S23 may be executed simultaneously with the steps S21 and S22, instead of the step S41.

The specific details and effects of example 1 of the engineering inspection method provided by the second embodiment can be referred to the specific contents of example 1 of the engineering inspection apparatus provided by the first embodiment.

(example 2)

As shown in fig. 6, in example 2 of the second embodiment, the step S20 of the engineering verification method further includes a step S24, compared to example 1 of the second embodiment.

In step S24, the lighting system testing unit 24 tests the lighting system using the lighting facility selected by the point selection.

In the case where the subsystem test module 20 includes the lighting system test unit 24, in the above-described step S23, the steps S231 and S232 may be included.

In step S231, it is determined whether the video surveillance system test unit 23 is performing a test at night. If yes, the process proceeds to step S232.

In step S232, a part or all of the lighting selection points selected by the lighting system test unit 24 are selected for the video surveillance system test.

In addition, the S23 step may further include the S233 step.

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

In step S233, a normal video surveillance system test is performed. The normal video surveillance system test is the same test as the test without the determination at S231, and may be performed by selecting an arbitrary camera.

By executing the steps S231 and S232, the problem that the video monitoring system cannot be used or the video monitoring system cannot be used due to poor shooting effect of the camera when the test is carried out at night can be solved. Therefore, the video monitoring system testing step S23 and the lighting system testing step S24 can be connected by utilizing the steps S231 and S232, invalid or poor-effect video monitoring system testing can be reduced, and the efficiency and the accuracy of engineering inspection can be improved.

The specific details and effects of example 2 of the engineering inspection method provided by the second embodiment can be referred to the specific contents of example 2 of the engineering inspection device of the first embodiment.

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

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

In the embodiment, targeted engineering inspection can be performed on each subsystem of the nuclear facility physical protection system, meanwhile, the operability is high, and comprehensive and complete engineering inspection results can be obtained.

Since the operations of steps S25 to S35 are relatively independent, they may be executed in parallel or in series, and this is not particularly limited, and since steps S21 to S24 may be executed independently and in parallel, fig. 7 shows only one example of the parallel execution of all steps S21 to S35.

However, examples 1 to 3 of the second embodiment may be combined with example 4.
