Description

Technical Field

[0001] This invention relates to the field of security system technology, specifically to an electronic fence security terminal and its operation method. Background Technology

[0002] The electronic fence security system for train platforms is mainly used for early warning of illegal intrusion by pedestrians around the platform. Traditional security systems primarily rely on image acquisition and analysis to deter intruders. While traditional systems use wide-angle or panoramic cameras to achieve large-area coverage, the lack of refined area segmentation and positioning mechanisms results in a cluttered monitoring screen with numerous background interferences. Especially when distinguishing between multiple real intruders and environmental distractions within a large coverage area, false alarms are often triggered by non-threatening moving objects. Therefore, it is difficult to quickly and accurately locate specific risk points in complex scenarios, leading to significant delays and misjudgments in risk response, thus reducing the system's reliability and practicality. To address this, an electronic fence security terminal and its operating method are proposed. Summary of the Invention

[0003] To address the problems in the prior art, this invention provides an electronic fence security terminal and its operation method.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an electronic fence security terminal, wherein the security terminal divides the platform into an internal movement area, an internal warning area, and a security early warning boundary, wherein a security terminal processing unit is provided in the security early warning boundary, wherein the security early warning boundary is divided into a security warning range and is used to cooperate with the security terminal processing unit to detect and screen non-active obstacles for terminal intrusion; The security early warning boundary is set as two sets symmetrically distributed front and back. The security terminal processing unit is arranged in one of the security early warning boundary surfaces. The inner side of the security early warning boundary is divided into several matrix recognition surfaces. Each matrix recognition surface has several measurement point cells arranged in a matrix distribution. Each matrix recognition surface area is provided with a laser expansion unit adapted to the measurement point cells. The laser expansion units are arranged in a rectangular distribution and cover the outer perimeter of the matrix recognition surface. One side of the security terminal processing unit is equipped with a non-active intrusion detection module. There are at least two sets of these modules, each with a detection surface covering two opposing security warning boundary areas. Each non-active intrusion detection module includes an image acquisition unit and a millimeter-wave radar sequence group, which are longitudinally symmetrically distributed. Preferably, the image acquisition unit is used to acquire image data within the matrix recognition surface area, and to perform active or non-active obstacle verification and identification based on whether there is cross-coverage between several laser expansion units inside it.

[0005] Preferably, the millimeter-wave radar sequence group and the matrix identification surface distribution surface are arranged horizontally. The millimeter-wave radar sequence group is used to obtain the coverage area of ​​the matrix identification surface corresponding to active or non-active obstacles, and to provide approval data to the security terminal processing unit according to the area array scanning parameters of active or non-active obstacles in the coverage area.

[0006] Preferably, each laser display unit in the matrix recognition surface is equipped with an independent edge computing gateway that is electrically connected to the security terminal processing unit.

[0007] Preferably, each of the matrix recognition surfaces is provided with a local acquisition data transmission unit. The local acquisition data transmission unit is used to capture the cross-coverage image data of the laser expansion unit and the approval data of the millimeter-wave radar sequence group, and upload them to the security terminal processing unit through an independent edge computing gateway.

[0008] Preferably, the security terminal processing unit is equipped with an audible and visual alarm, a radio frequency identification unit, a storage hard disk, a switch, and a processor group. The image acquisition unit and the millimeter-wave radar sequence group are both connected to the storage hard disk via signal. The storage hard disk and the processor group are both connected to an external remote monitoring terminal via the switch. The audible and visual alarm includes a radio frequency identification unit that is connected to the processor group via signal.

[0009] Preferably, the security terminal processing unit is further provided with an end fence section at the end away from the security early warning boundary surface, and an independent wide-angle camera unit is provided on one side of the security terminal processing unit. The independent wide-angle camera unit is used to independently cover and collect images of the end fence section area.

[0010] Preferably, an operation method for an electronic fence security terminal includes the following steps: Step S1: The entrance warning line and track warning line are set as the platform warning zone, and the terminal intrusion line is set as the platform end security warning zone for risk classification. When personnel enter the entrance warning line or track warning line area, the image acquisition unit operates independently to acquire low-risk warning images and drives away personnel from the platform through the security terminal processing unit. Step S2: When a person moves from the movement area within the platform to the end of the platform, the image acquisition unit first acquires the image of their entry route as record data. When the person enters the security warning boundary area, the image acquisition unit starts to independently acquire the image data of the corresponding matrix recognition area reached by the person, and performs active or non-active obstacle verification and identification based on the cross-coverage surface generated by the laser amplification unit in the measuring point cell. Step S3: When multiple laser amplification units set inside the measuring point cell in a single matrix recognition surface are all blocked by obstacles, the originating signal of the laser amplification unit is affected by the obstacles, and the integrity of the image information acquired by the image acquisition unit is limited. At this time, the security terminal processing unit controls the millimeter-wave radar sequence group to verify the height plane of the obstacle in the corresponding matrix recognition surface area through the millimeter-wave radar signal. If the interference height plane is lower than the preset value, it is identified as a non-active intrusion obstacle. At this time, the record data obtained by the image acquisition unit is deleted. Step S31: The security terminal processing unit controls the millimeter-wave radar sequence group to verify the height plane of the interference of the obstacle in the corresponding matrix recognition area through the millimeter-wave radar signal. If the interference height plane is higher than the preset value, and multiple laser amplification units set inside the measuring point cell in a single matrix recognition area are all blocked by the obstacle, the security terminal processing unit verifies it as an active intrusion obstacle, the security terminal processing unit starts the audible and visual alarm, and uploads the image collected by the image acquisition unit for archiving. Step S32: When an independent laser expansion unit set inside the measuring point cell in a single matrix recognition surface is triggered, the security terminal processing unit eliminates the locally generated obstacle occlusion error.

[0011] Compared to existing technologies, the advantages of this invention are as follows: By setting up a security early warning boundary surface, matrix recognition surface, and measuring point cells in the terminal intrusion line area, the end position of the security terminal processing unit at the station is set as a grid-like monitoring network. The matrix arrangement of laser amplification units forms a laser recognition surface grid, which can quickly verify the specific range of the intrusion based on the specific grid range of the penalty, realize regional grid-based monitoring, quickly respond to the intrusion location for point-to-point removal, and directly capture the intrusion local through the image acquisition unit, ensuring the integrity of image data and the accuracy of the image acquisition center. In actual monitoring, the intruder volume contour can be confirmed by the crossing range of multiple laser amplification units set inside the measuring point cells in a single matrix recognition surface when they are subjected to obstacles, in conjunction with the plane height parameters generated by the millimeter-wave radar sequence group, so that the security terminal processing unit can reduce false alarms after completing image analysis.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-3 As shown, the electronic fence security terminal of the present invention divides the platform into an internal movement zone 1, an internal warning zone 2, and a security warning boundary 3. A security terminal processing unit 4 is provided in the security warning boundary 3. The security warning boundary 3 is divided into a security warning range and is used to cooperate with the security terminal processing unit 4 to detect and screen non-active obstacles that the terminal intrudes into. The security early warning boundary surface 3 is set as two sets symmetrically distributed front and back. The security terminal processing unit 4 is arranged in one of the security early warning boundary surfaces 3. The inner side of the security early warning boundary surface 3 is divided into several matrix recognition surfaces 31. Each matrix recognition surface 31 has several measurement point cells 32 arranged in a matrix distribution. Each matrix recognition surface 31 is equipped with a laser expansion unit 33 that is adapted to the measurement point cells 32. The laser expansion units 33 are arranged in a rectangular distribution and cover the outer periphery of the matrix recognition surface 31. A non-active intrusion detection module 5 is provided on one side of the security terminal processing unit 4. There are at least two sets of non-active intrusion detection modules 5, and their detection surfaces cover two opposing security warning boundary areas 3 respectively. The non-active intrusion detection module 5 includes an image acquisition unit 51 and a millimeter-wave radar sequence group 52. The image acquisition unit 51 and the millimeter-wave radar sequence group 52 are longitudinally symmetrically distributed. In this embodiment, to address the problem that while existing technologies employ wide-angle or panoramic cameras to achieve large-area coverage, the lack of refined area division and positioning mechanisms leads to cluttered targets and background interference in the monitored image, making it difficult to quickly and accurately locate specific risk points in complex scenes, this invention proposes an electronic fence security terminal. This terminal sets up a grid-like monitoring network at the end of the platform where the security terminal processing unit 4 is located by using a security warning boundary surface 3, a matrix recognition surface 31, and measuring point cells 32 set in the terminal intrusion line 23 area. A laser recognition surface grid is formed by the matrix arrangement of laser amplification units 33, which can then be used to quickly and accurately locate specific risk points in complex scenes. The grid range of the physical punishment system quickly verifies the specific matrix identification surface 31 range of the intrusion, realizing regional grid-based monitoring, rapidly responding to the intrusion location for point-to-point removal, and directly capturing the intrusion local through the image acquisition unit 51, ensuring the integrity of image data and the accuracy of the image acquisition center. In actual monitoring, the multiple laser amplification units 33 set inside the measuring point cell 32 in a single matrix identification surface 31 can be used to determine the crossing range when crossing obstacles, in conjunction with the plane height parameters generated by the millimeter-wave radar sequence group 52, confirming the volume and outline of the intruder, so that the security terminal processing unit 4 can reduce false alarms after completing image analysis.

[0017] In one optional embodiment of this example, the image acquisition unit 51 is used to acquire image data within the area of ​​the matrix recognition surface 31, and to perform active or non-active obstacle verification and identification based on whether there is cross-coverage between several laser expansion units 33 on its inner side.

[0018] In this embodiment, as shown in the accompanying drawings. Figure 3 As shown, since the inner side of the matrix recognition surface 31 is divided into multiple cells by measuring point cells 32, the laser amplification unit 33 corresponds to the independent cells set by the measuring point cells 32. When the laser amplification unit 33 is blocked by an obstacle in the cell where it is located, the laser amplification surface generated by the laser amplification unit 33 is obstructed. If an intruder enters the area where the matrix recognition surface 31 is located, the active intruder coverage will be multiple and will cross the emission surface of the laser amplification unit 33, thus distinguishing between the real intruder and environmental interference. At the same time, this monitoring and early warning mode, by setting a gridded detection matrix composed of the matrix recognition surface 31, measuring point cells 32 and laser amplification unit 33 within the security early warning boundary surface 3, decomposes a large monitoring area into multiple independent monitoring units. This structure can accurately locate the intrusion event to a specific cell, greatly improving the positioning accuracy.

[0019] In one optional embodiment of this example, the millimeter-wave radar sequence group 52 and the matrix identification surface 31 are arranged horizontally. The millimeter-wave radar sequence group 52 is used to obtain the coverage area of ​​the matrix identification surface 31 corresponding to active or non-active obstacles, and to provide approval data to the security terminal processing unit 4 according to the area array scanning parameters of active or non-active obstacles in the coverage area.

[0020] In this embodiment, when multiple laser imaging units 33 in the matrix identification surface 31 are triggered, the plane height parameters generated by the millimeter-wave radar sequence group 52 confirm the volume profile of the intruder, which is used to verify the height of the intruder for a second time, and then to remove the environmental interference data for a second time, so as to delete the image generated by the image acquisition unit 51 after the previous trigger, thereby reducing the storage burden in the security terminal processing unit 4.

[0021] In an optional embodiment of this example, each laser display unit 33 in the matrix recognition surface 31 is provided with an independent edge computing gateway and electrically connected to the security terminal processing unit 4.

[0022] In an optional embodiment of this example, each matrix recognition surface 31 is provided with a local acquisition data transmission unit 34. The local acquisition data transmission unit 34 is used to capture the cross-coverage image data of the laser expansion unit 33 and the approval data of the millimeter-wave radar sequence group 52, and upload them to the security terminal processing unit 4 through an independent edge computing gateway.

[0023] In this embodiment, by setting an independent edge computing gateway and a local data acquisition and transmission unit 34 in each matrix recognition surface 31, data can be processed and filtered locally. After the security terminal processing unit 4 deletes the non-active intruder image data acquired by the image acquisition unit 51, only active intruders or abnormal data that meet the scope of active intruders are uploaded to the security terminal processing unit 4, thereby greatly reducing the data processing pressure of the central node, reducing network bandwidth occupation, and ensuring that the system's response speed and real-time performance are more stable.

[0024] In one optional embodiment of this example, the security terminal processing unit 4 is equipped with an audible and visual alarm, a radio frequency identification unit, a storage hard disk, a switch, and a processor group. The image acquisition unit 51 and the millimeter-wave radar sequence group 52 are both connected to the storage hard disk via signal. The storage hard disk and the processor group are both connected to an external remote monitoring terminal via the switch. The audible and visual alarm includes a radio frequency identification unit that is connected to the processor group via signal.

[0025] In this embodiment, the radio frequency identification unit is used to identify the identification card. When staff enter the security warning boundary 3 area, carrying the identification card will deactivate the security terminal processing unit 4 and the non-active intrusion approval module 5, thus avoiding false alarms from the audible and visual alarms.

[0026] In one optional embodiment of this example, the end of the security terminal processing unit 4 away from the security warning boundary surface 3 is also provided with an end fence section 24, and an independent wide-angle camera unit 6 is provided on one side of the security terminal processing unit 4. The independent wide-angle camera unit 6 is used to independently cover and collect images of the end fence section 24 area.

[0027] In this embodiment, since the area between the end fence section 24 and the security warning boundary 3 is small, clear and comprehensive image information can be obtained by independently detecting this area using the independent wide-angle camera unit 6, without the need for grid monitoring.

[0028] The operating method of the present invention includes the following steps: Step S1: The entry warning line 21 and the track warning line 22 are set as the platform warning zone, and the terminal intrusion line 23 is set as the platform end security warning zone for risk classification. When personnel enter the area of ​​the entry warning line 21 or the track warning line 22, the image acquisition unit 51 operates independently to acquire low-risk warnings and drives away personnel from the platform through the security terminal processing unit 4. Step S2: When a person moves from the movement zone 1 within the platform to the end of the platform, the image acquisition unit 51 first acquires the image of their entry route as record data. When the person enters the security warning boundary surface 3 area, the image acquisition unit 51 starts to independently acquire the image data of the corresponding matrix recognition surface 31 area reached by the person, and performs active or non-active obstacle verification and identification based on the cross-covering surface generated by the laser expansion unit 33 in the measuring point cell 32. In step S3, when multiple laser expansion units 33 set inside the measuring point cell 32 in a single matrix recognition surface 31 are all blocked by obstacles, the originating signal of the laser expansion unit 33 is affected by the obstacles, and the integrity of the image information acquired by the image acquisition unit 51 is limited. At this time, the security terminal processing unit 4 controls the millimeter-wave radar sequence group 52 to verify the height plane of the obstacle in the corresponding matrix recognition surface 31 area through the millimeter-wave radar signal. If the interference height plane is lower than the preset value, it is identified as a non-active intrusion obstacle. At this time, the record data obtained by the image acquisition unit 51 is deleted. Step S31: The security terminal processing unit 4 controls the millimeter-wave radar sequence group 52 to verify the height plane of the obstacle in the corresponding matrix recognition surface 31 area through the millimeter-wave radar signal. If the interference height plane is higher than the preset value, and multiple laser expansion units 33 set inside the measuring point cell 32 in a single matrix recognition surface 31 are all blocked by the obstacle, the security terminal processing unit 4 verifies it as an active intrusion obstacle, the security terminal processing unit 4 starts the sound and light alarm, and uploads the image collected by the image acquisition unit 51 for archiving. When the independent laser expansion unit 33 set inside the measuring point cell 32 in the single matrix recognition surface 31 is triggered in step S32, the security terminal processing unit 4 eliminates the locally generated obstacle occlusion error.
