Description

Technical Field

[0001] This invention belongs to the field of detection technology, specifically relating to a device and method for detecting the alarm response time of a perimeter intrusion alarm system. Background Technology

[0002] Perimeter intrusion alarm systems are commonly used security systems in important locations such as railways, airports, government agencies, protected areas, schools, and hospitals. These systems utilize sensor and electronic information technologies to detect unauthorized entry or attempted unauthorized entry into a protected area, preventing perimeter intrusion incidents. They typically consist of front-end alarm equipment, a transmission network, and a management center. The front-end alarm equipment is usually installed on or at the edge of the perimeter fence, while the management center typically houses the alarm control panel and display software; these two locations are usually relatively far apart.

[0003] Perimeter intrusion alarm systems generally employ two types of detection technologies: passive and active. Passive detection technologies, such as electronic pulse fences and vibration fiber optics, require the front-end alarm devices or sensors to be fixed to the perimeter. They trigger an alarm upon detecting perimeter vibration or an object touching the sensor. Active detection technologies, such as leaky cables, visible light cameras combined with thermal imaging cameras, and millimeter-wave radar electromagnetic wave detection, typically define virtual electronic defense zones in the system software. These virtual zones can cover a large area both inside and outside the perimeter fence. Once an object crosses the boundary of this virtual electronic defense zone, it can be detected and trigger an alarm.

[0004] "Alarm response time" is one of the important indicators for measuring the detection performance of a perimeter intrusion alarm system. According to the requirements of the "Technical Standard for Security Engineering" (GB50348), the alarm response time of a perimeter intrusion alarm system with security level 4 should not exceed 2 seconds, and the alarm response time of a perimeter intrusion alarm system with security levels 2 and 3 should not exceed 5 seconds. That is, when someone illegally enters or attempts to illegally enter the protected area, the perimeter intrusion alarm system should sound an alarm within 2 seconds or 5 seconds.

[0005] For a long time, the testing of the "alarm response time" performance indicator of perimeter intrusion alarm systems has been unscientific and inaccurate. For example, the testing work generally requires two people, A and B, as follows:

[0006] When testing a perimeter intrusion alarm system using passive detection technology, inspector A manually touches the perimeter to trigger the alarm. Simultaneously, inspector A records the start time of the touch, while inspector B records the alarm time at the management center. The "alarm response time" is then calculated by determining the time difference between the times recorded by B and A. However, the human touch action involves a reflexive process, which can introduce measurement errors in the trigger time. Furthermore, because A and B are relatively far apart, the clocks of their detection tools may be out of sync, leading to inaccurate results.

[0007] When testing a perimeter intrusion alarm system employing active detection technology, the alarm is triggered by inspector A quickly crossing from the outside of the virtual electronically protected area boundary into the inside. Inspector A records the time it takes to cross the virtual electronically protected area boundary, while inspector B records the system alarm time at the management center. The time difference is calculated to determine the "alarm response time." However, the human action of crossing involves a reflex, making it difficult to accurately record the time of crossing the virtual electronically protected area boundary. Furthermore, due to the distance between inspectors A and B, the clocks of their detection tools may have synchronization errors, leading to inaccurate detection results.

[0008] Given that the alarm response time of a perimeter intrusion alarm system should not exceed 2s or 5s, the measurement error caused by detection methods that involve human touching of the perimeter or crossing the boundary of the virtual electronic defense area is obviously not negligible. How to scientifically, objectively, and accurately detect the performance indicators of the alarm response time of a perimeter intrusion alarm system is currently a challenge. Summary of the Invention

[0009] The purpose of this invention is to solve the problems existing in the prior art and provide a device and method for detecting the alarm response time of a perimeter intrusion alarm system. This invention solves the problems that existing detection methods are greatly affected by human factors, are unscientific, and have inaccurate results. It can automatically detect the alarm response time performance index of the perimeter intrusion alarm system. The method is scientific, the results are accurate, and it is easy to use.

[0010] This invention is achieved through the following technical solution:

[0011] In a first aspect, the present invention provides an apparatus for detecting the alarm response time of a perimeter intrusion alarm system, the apparatus comprising: a control computer, a local area network control unit, and an intrusion actuation unit;

[0012] The control computer can communicate with the alarm host and the local area network control unit of the perimeter intrusion alarm system under test, respectively.

[0013] The local area network control unit is able to communicate with the intrusion actuation unit.

[0014] A further improvement of the present invention is that:

[0015] The control computer is connected to the alarm host of the perimeter intrusion alarm system under test via a wired connection.

[0016] The control computer is connected to the local area network control unit via a wired connection;

[0017] The local area network control unit is connected to the intrusion actuation unit via a wired connection.

[0020] The control computer can provide time synchronization to the clock synchronization unit;

[0021] Upon receiving the release start command from the control computer, the actuation control unit controls the intrusion actuation unit to perform actions, while the data recording unit records the time when the release start command is received.

[0022] A further improvement of the present invention is that:

[0023] The intrusion actuation unit includes: a base, a column, a controllable pop-out mechanism, and a cantilever mechanism;

[0024] The lower end of the column is fixedly connected to the base;

[0025] The controllable pop-out mechanism is located on the upper part of the column;

[0026] One end of the cantilever mechanism is hinged to the controllable pop-out mechanism, while the other end is suspended in the air.

[0027] The controllable pop-out mechanism can lock or pop out the cantilever mechanism.

[0028] A further improvement of the present invention is that:

[0029] A clamp is provided on the cantilever mechanism near the suspended end;

[0030] The clamp can hold the soft cloth.

[0031] Preferably, heating wires are embedded in the soft cloth.

[0032] A second aspect of the present invention provides a method for detecting the alarm response time of a perimeter intrusion alarm system, the method comprising:

[0033] The first step is to fix the intrusion actuation unit at the detection position of the intrusion alarm system of the perimeter to be tested;

[0034] The second step is to connect the control computer to the alarm host of the perimeter intrusion alarm system under test via a local area network and synchronize their clocks:

[0035] The third step is to connect the local area network control unit to the control computer and the intrusion actuation unit via the local area network, and at the same time, synchronize the clock of the local area network control unit with that of the control computer.

[0036] The fourth step is to adjust the cantilever mechanism of the intrusion actuation unit to the retracted state;

[0037] Fifth, the control computer sends a release start command to the local area network control unit;

[0038] Step 6: After receiving the release start command, the local area network control unit immediately starts the intrusion actuation unit, records the time t0 when the release start command is received, and sends the time t0 to the control computer.

[0039] Step 7: Record the alarm time t1 of the perimeter intrusion alarm system under test;

[0040] Step 8: Calculate the alarm response time Δt of the perimeter intrusion alarm system under test using the following formula:

[0041] Δt = t1 - t0.

[0042] Preferably, in the first step, if the perimeter intrusion alarm system to be tested uses passive detection technology, the intrusion actuation unit is placed at the edge of the perimeter or at the edge of the detection sensor of the perimeter intrusion alarm system to be tested.

[0043] Preferably, in the first step, if the perimeter intrusion alarm system to be tested uses an active detection technology other than thermal imaging detection technology, the intrusion actuation unit is placed outside the boundary of the virtual electronic defense area defined by the perimeter intrusion alarm system to be tested, and the soft cloth is clamped by the clamp on the cantilever mechanism.

[0044] Preferably, in the first step, if the perimeter intrusion alarm system to be tested uses thermal imaging detection technology, the intrusion actuation unit is placed outside the boundary of the virtual electronic defense area defined by the perimeter intrusion alarm system to be tested, and the soft cloth is clamped by the clamp on the cantilever mechanism while the heating wire is heated.

[0045] Compared with the prior art, the beneficial effects of the present invention are:

[0046] (1) The present invention activates the intrusion actuation unit by control command to quickly pop out the cantilever mechanism, automatically records the time, and triggers the alarm of the perimeter intrusion alarm system to be measured, thus achieving the effects of automated detection, fast triggering time and small measurement error.

[0047] (2) The present invention connects the measuring device to the perimeter intrusion alarm system under test via a local area network, eliminating the measurement error caused by the two inspectors being far apart and having out-of-sync clocks.

[0048] (3) This invention can be used to detect both passive and active perimeter intrusion alarm systems. When used to detect passive perimeter intrusion alarm systems, the cantilever mechanism of the device generates an alarm by rapidly extending and touching the perimeter or sensor. When used to detect active perimeter intrusion alarm systems, the cantilever mechanism and the soft cloth rapidly extend to simulate an intruder crossing the boundary of a virtual electronic defense area, and the heating wire in the soft cloth can also simulate the infrared characteristics of the intruder. This invention solves the problems of existing perimeter intrusion alarm system alarm response time performance index testing tools being unsuitable for perimeter intrusion alarm systems using different technical principles and inconsistent testing methods, achieving the effects of strong universality, unified testing methods, and simple use.

Detailed Implementation

[0057] The present invention will now be described in further detail with reference to the accompanying drawings:

[0058] Traditional methods of detecting intrusion alarms in perimeter security systems, relying on human interaction with the perimeter or simulated crossing of virtual electronically protected boundaries, suffer from measurement errors in trigger start time due to delays caused by bodily reflexes. To address this technical issue, such as... Figures 1-6 As shown, the present invention provides an apparatus and method for detecting the alarm response time of a perimeter intrusion alarm system.

[0059] like Figure 1 As shown, the device for detecting the alarm response time of the perimeter intrusion alarm system includes: a control computer 1, a local area network control unit 2, and an intrusion actuation unit 3; the control computer 1 can communicate with the alarm host 4 of the perimeter intrusion alarm system under test, and at the same time, the control computer 1 can communicate with the local area network control unit 2, and the local area network control unit 2 can communicate with the intrusion actuation unit 3.

[0060] In this embodiment, the control computer 1 is connected to the alarm host 4 of the perimeter intrusion alarm system under test via a wired connection (cable). Simultaneously, the control computer 1 is connected to the local area network control unit 2 via a wired connection, and the local area network control unit 2 is connected to the intrusion actuation unit 3 via a wired connection. The purpose of using a wired connection in this embodiment is to avoid the time measurement error introduced by the latency of a wireless connection. Of course, if the wireless connection can guarantee low latency, the wired connection methods described above can also be replaced with wireless connections. For example, if the control computer 1 and the alarm host 4 of the perimeter intrusion alarm system under test are not far apart, they can directly connect wirelessly through two wireless routers (one transmitting and one receiving), resulting in low latency. If the control computer 1 and the alarm host 4 of the perimeter intrusion alarm system under test are far apart, requiring multiple wireless routers for relay communication, the latency may be high, for example, exceeding 100ms. This introduces a measurement error of more than 100ms, making the measurement result less accurate than using a direct wired connection.

[0061] Specifically, the local area network control unit 2 includes: a clock synchronization unit, an actuation control unit, a data recording unit, and a power supply unit. The control computer 1 can provide time synchronization to the clock synchronization unit (i.e., through a connected cable, the control computer 1 provides time synchronization to the clock synchronization unit). Upon receiving a release start command from the control computer 1, the actuation control unit controls the intrusion actuation unit 3 to perform an action (i.e., the actuation control unit can control the controllable ejection mechanism 303 in the intrusion actuation unit 3 to release the cantilever mechanism 304 through a connected cable). Simultaneously, the data recording unit records the time t0 at which the release start command is received and sends the time t0 to the control computer 1.

[0062] More specifically, the clock synchronization unit uses existing products, such as a clock synchronization chip based on the "IEEE 1588 Precision Clock Synchronization Protocol Standard for Network Measurement and Control Systems" and resistors, capacitors, etc., to form a clock synchronization unit circuit. This clock synchronization unit circuit is connected to the control computer 1 via a network cable. The control computer 1 can be set to send its own clock to the clock synchronization unit circuit every 1 second or at any time interval. The precision clock synchronization technology of IEEE 1588 network measurement and control systems is common knowledge in the field. Relevant clock synchronization chip products include AD9543, AD9545, DP83640, Si5348, ACS9522, etc., which will not be described in detail here.

[0063] The actuation control unit can use common microcontrollers, ARM processors, FPGA chips, etc., as the main control processor, plus related resistors, capacitors, etc. to form the circuit. The control computer 1 sends control signals to the actuation control unit via cables. After receiving the signal, the actuation control unit controls the controllable ejection mechanism 303 in the intrusion actuation unit 33 through the signal lines on the circuit board. The above control circuit is common knowledge in the art and will not be described in detail here.

[0064] The power supply unit supplies power to the clock synchronization unit, actuation control unit, and data recording unit, and can also supply power to the heating wire 307 in the intrusion actuation unit 3. The power supply unit can use batteries, AC power, etc.

[0065] In actual production, the local area network control unit 2 can be an integrated circuit board. This board includes a clock synchronization unit, an actuation control unit, a data recording unit, a power supply unit, and further includes a network port. The main control processor on this board is the microcontroller, ARM processor, or FPGA chip used by the actuation control unit. This main control processor is connected to the clock synchronization unit, data recording unit, power supply unit, and network port. The main control processor can read data from the data recording unit and send the data to the control computer 1 via the network cable. The design method and specific implementation of this type of circuit are well-known and commonly used techniques in the fields of electronic circuits and instrument science. They will not be elaborated further here.

[0066] like Figure 2 As shown, in this embodiment, the intrusion actuation unit 3 includes a base 301, a column 302, a controllable ejection mechanism 303, and a cantilever mechanism 304. The lower end of the column 302 is fixedly connected to the base 301. The controllable ejection mechanism is disposed on the upper part of the column 302. One end of the cantilever mechanism 304 is hinged to the controllable ejection mechanism 303, and the other end is suspended. The controllable ejection mechanism 303 can lock or eject the cantilever mechanism 304, thereby changing the angle between the cantilever mechanism 304 and the column 302.

[0067] Specifically, the cantilever mechanism 304 adopts a straight rod. When the controllable pop-out mechanism 303 is not activated, the cantilever mechanism 304 is in a retracted state, that is, parallel to the column. When the controllable pop-out mechanism 303 is activated, the cantilever mechanism 304 pops out and is perpendicular to the column 302.

[0068] The controllable ejection mechanism 303 can be implemented using various existing structures. For example, the controllable ejection mechanism 303 can adopt the ejection structure of an existing spring knife (see https: / / b23.tv / CdEDhV0). In the initial state, the knife is in the retracted state. When the shaft lock is pressed by the button on the spring knife, the knife is ejected. Due to the action of the spring (or spring plate), the knife stop shaft will move back and forth, and then press against the two arc-shaped grooves at the tail of the knife (the shape and size of the arc-shaped grooves can control the angle between the knife and the handle after the knife is opened). Specifically, in this embodiment, the column 302 serves as the handle of the spring knife, and the cantilever mechanism 304 serves as the knife. The connection between the cantilever mechanism 304 and the controllable pop-out mechanism 303 has an arc-shaped groove, similar to the tail of a knife. Simultaneously, the shaft lock in the spring knife is replaced with an electromagnet or an electronic switch. Energizing the electromagnet or electronic switch automatically presses and releases the shaft lock (refer to the principle and application of existing electromagnetic relays and the structure of electromagnets), achieving the same function as manually pressing the button on a spring knife. Initially, the cantilever mechanism 304 is parallel to the column 302 and is held in place by the controllable pop-out mechanism 303. When the electromagnet or electronic switch is energized, the cantilever mechanism 304 springs out like a knife, forming a 90-degree angle with the column 302. The electromagnet and electronic switch are well-known products in the art, and their structure will not be described in detail here. The actuation control unit of the local area network control unit 2 outputs an electrical signal to open the electromagnet or electronic switch.

[0069] Furthermore, a clamp 305 is provided on the cantilever mechanism 304 near the suspended end, which can clamp the soft cloth 306. Preferably, in order to simulate the infrared characteristics of the human body, an electric heating wire 307 is embedded in the soft cloth 306. For example, the electric heating wire can be embedded in the soft cloth 306 in an S-shape (the soft cloth can be made using existing methods for manufacturing electric blankets; as long as it can generate heat, it can simulate the infrared characteristics of humans or animals). A power plug is provided at one end of the electric heating wire 307. A power cord is led out from the power supply unit of the local area network control unit 2, runs along the column 302 and the cantilever mechanism 304 to the top of the plug of the electric heating wire 307, where a power socket for connecting the power cord is provided. When the electric heating wire 307 needs to be used, the plug is connected to the power socket.

[0070] In this embodiment, the soft cloth 306 is used to simulate an intruding object. If a plate with heating wires were used, its weight would be heavier than the soft cloth, and since the plate is a rigid material, it might be damaged or injure someone when the cantilever mechanism 304 pops out. Using a soft cloth with heating wires effectively simulates a person or animal entering the electronically secured area of ​​the perimeter. As long as the area is large enough and has infrared signatures, the testing effect is achieved. During use, the soft cloth 306 is clamped with a clamp 305; when not in use, the soft cloth 306 is removed from the clamp 305. The clamp 305 can be any existing clamp, as long as it clamps tightly enough to ensure the soft cloth 306 does not detach when the cantilever mechanism 304 pops out.

[0071] like Figure 4 As shown, the present invention also provides a method for detecting the alarm response time of a perimeter intrusion alarm system. The method utilizes the aforementioned apparatus for detecting the alarm response time of a perimeter intrusion alarm system, and includes the following steps:

[0072] The first step is to fix the intrusion actuation unit 3 at the detection position of the perimeter intrusion alarm system under test:

[0073] Fixed Intrusion Actuation Unit: Based on the technical principles used by the perimeter intrusion alarm system under test, the intrusion actuation unit 3 is fixed to the ground at the detection location of the perimeter intrusion alarm system using base 301. Any common and feasible fixing method can be used, such as cement counterweight, anchoring, or bolt connection, which will not be elaborated upon here.

[0074] In this embodiment, as Figure 5 As shown, if the perimeter intrusion alarm system under test adopts passive detection technology, the intrusion actuation unit 3 is placed at the edge of the perimeter or the edge of the detection sensor of the perimeter intrusion alarm system under test. As long as the cantilever mechanism 304 can touch the perimeter or the sensor when it pops out, the soft cloth 306 is not installed.

[0075] In this embodiment, as Figure 6 As shown, if the perimeter intrusion alarm system under test uses an active detection technology other than thermal imaging, the intrusion actuation unit 3 is placed outside the boundary of the virtual electronic defense area defined by the perimeter intrusion alarm system under test, and the soft cloth 306 is clamped by the clamp 305 on the cantilever mechanism 304. If the perimeter intrusion alarm system under test uses thermal imaging detection technology, the intrusion actuation unit 3 is placed outside the boundary of the virtual electronic defense area defined by the perimeter intrusion alarm system under test, and the soft cloth 306 is clamped by the clamp 305 on the cantilever mechanism 304, and the heating wire is heated (for example, by connecting the power plug of the heating wire 307 to a power socket). After the heating wire is heated, it can simulate the infrared characteristics of the human body.

[0076] The second step is to connect the control computer 1 to the alarm host 4 of the perimeter intrusion alarm system under test and synchronize their clocks:

[0077] Connect control computer 1 to the alarm host 4 of the perimeter intrusion alarm system under test via a local area network (LAN). Simultaneously, synchronize the clocks of control computer 1 and the alarm host 4 of the perimeter intrusion alarm system under test (since they are connected via LAN, setting the clock synchronization server IP address of control computer 1 to the IP address of the alarm host 4 of the perimeter intrusion alarm system under test will achieve clock synchronization between the two computers). Figure 7 As shown in the figure, this eliminates measurement errors.

[0078] The third step is to connect the local area network control unit 2 to the control computer 1 and the intrusion actuation unit 3 via the local area network. At the same time, the clock of the local area network control unit 2 is synchronized with that of the control computer 1, thus eliminating measurement errors.

[0079] Fourth step: Adjust the cantilever mechanism 304 of the intrusion actuation unit 3 to the retracted state:

[0080] like Figure 3 As shown, the cantilever mechanism 304 of the intrusion actuation unit 3 is adjusted to the retracted state. For example, the cantilever mechanism 304 can be manually pressed to make it be locked by the controllable pop-out mechanism 303. At this time, the cantilever mechanism 304 is in the retracted state. In the retracted state, the cantilever mechanism 304 is close to the edge of the column 302 and parallel to the column 302.

[0081] Fifth step: Control computer 1 sends a release start command to local area network control unit 2;

[0082] Step 6: Upon receiving the release start command, the local area network control unit 2 immediately activates the intrusion actuation unit 3, simultaneously records the time t0 at which the release start command was received, and sends the time t0 to the control computer 1.

[0083] Upon receiving the release start command, the local area network control unit 2 immediately activates the intrusion actuation unit 3. The cantilever mechanism 304 extends and touches or crosses the boundary of the virtual electronic defense area of ​​the intrusion alarm system 4 to enter the inner side of the boundary. Simultaneously, the data recording unit of the local area network control unit 2 records the time t0 of receiving the release start command (the time difference between the immediate activation of the intrusion actuation unit upon receiving the release start command and the very small intrusion actuation unit is negligible; therefore, recording the time t0 is sufficient) and sends the time t0 to the control computer 1.

[0084] Step 7: Record the alarm time t1 of the perimeter intrusion alarm system under test.

[0085] The alarm host 4 of the perimeter intrusion alarm system under test can send the alarm time t1 to the control computer 1, and the control computer 1 can record the alarm time t1 of the alarm host 4 of the perimeter intrusion alarm system under test. Alternatively, the alarm time t1 can be recorded directly on the alarm host 4 of the perimeter intrusion alarm system under test without sending the alarm time t1.

[0086] Step 8: Calculate the alarm response time of the perimeter intrusion alarm system under test using the following formula:

[0087] Δt = t1 - t0.

[0088] If the alarm host 4 of the perimeter intrusion alarm system under test sends the alarm time t1 to the control computer 1 in step 7, then the control computer 1 will calculate the alarm response time. If it does not send the alarm time, the alarm response time can be calculated manually.

[0089] This invention enables automatic detection of perimeter intrusion alarm systems based on different technical principles, with small measurement errors and simple operation.

[0090] The above technical solution is only one embodiment of the present invention. For those skilled in the art, based on the principles disclosed in the present invention, it is easy to make various types of improvements or modifications, and not limited to the technical solutions described in the specific embodiments of the present invention. Therefore, the foregoing description is only a preferred option and is not restrictive.
