Description

Technical Field

[0001] This invention relates to the field of platform security technology, and in particular, to an end-intrusion identification method. Background Technology

[0002] Currently, railway transportation, especially high-speed rail, has a large capacity, short departure intervals, and high passenger volume. Platform areas often experience crowding during passenger waiting and boarding / alighting, forcing station staff to spend more time and energy maintaining order. In the past, there have been instances of individual passengers rushing into the platform end areas and encroaching on the tracks, posing a significant safety risk to passengers and disrupting normal railway operations, causing substantial direct and indirect economic losses. To prevent passengers from entering the platform end areas, current security measures primarily rely on physical barriers and personnel patrols. This involves installing fences at the existing end areas and deploying a large number of personnel for monitoring. This approach is wasteful of human resources, ineffective, labor-intensive, inefficient, and cannot achieve 24 / 7 monitoring.

[0003] Currently, technologies have emerged that install lidar video devices at both ends of railway station platforms for security monitoring. These devices detect approaching personnel and trigger alarms. For example, Chinese invention patent CN115985028A discloses a railway platform end intrusion monitoring system and method. Using lidar video devices, it can acquire images of the target area at the platform end, perform lidar detection, and identify personnel using identification tags. Based on the detection signals, it determines whether personnel have entered the target area and whether they are on a whitelist. If personnel are found to be present and not on the whitelist, an alarm is generated and transmitted to the platform server and the station's integrated control room via a dedicated internal network. Simultaneously, audible and visual warnings and text alerts are issued to personnel entering the target area, achieving efficient and accurate platform end intrusion monitoring. This invention can replace traditional physical security and personnel patrol methods, improving the intrusion prevention effect at the platform end. It also boasts high monitoring efficiency and accuracy, enabling precise personnel identification and preventing false alarms.

[0004] However, the above-mentioned end-point intrusion monitoring design still has the following drawbacks: it can only perform intrusion monitoring, cannot effectively block personnel from intruding at the end, cannot effectively prevent malicious intrusion events at the end, cannot identify personnel approaching the end of the platform, and cannot ensure the security monitoring of intrusion at the end of the platform.

[0005] Therefore, in order to solve the above problems, it is necessary for us to design an end-intrusion identification method. Summary of the Invention

[0006] The purpose of this invention is to provide an end-point intrusion identification method, which sets up a security door at the end of the platform to effectively protect the end of the platform from intrusion, effectively block malicious intrusion, and issue different intrusion alarms based on the pedestrian's approach position and distance, thus ensuring the safe identification of intrusions at the end of the platform.

[0007] To achieve the above objectives, the present invention employs the following technical solution:

[0008] An end-intrusion detection method is provided for an end-intrusion detection structure. The structure includes a plurality of columns disposed at the end of a platform and an end safety gate formed by a controllable lifting and lowering pull rope disposed between two adjacent columns. The end safety gate is located at the longitudinal end of a platform safety gate for boarding and alighting passengers and is perpendicularly connected to the platform safety gate to form a rectangular closed safety gate. The pull rope of the end safety gate is normally closed at a first preset height. The structure also includes a detection unit for detecting pedestrian approach and an alarm unit for issuing an intrusion alarm.

[0009] The method includes the following steps:

[0010] When the detection unit detects that the distance between the pedestrian and the rope is less than the first predetermined distance and the distance between the pedestrian and the post is not greater than the distance between the pedestrian and the rope, the alarm unit will not issue an alarm.

[0011] When the detection unit detects that the distance between the pedestrian and the rope is less than the first predetermined distance and the distance between the pedestrian and the post is greater than the distance between the pedestrian and the rope, the alarm unit will issue a level one alarm.

[0012] When the detection unit detects that the distance between the pedestrian and the rope is less than the second predetermined distance and the distance between the pedestrian and the post is greater than the third predetermined distance, the alarm unit will issue a level two alarm.

[0013] As a preferred embodiment of the present invention, the column is further provided with an identification part;

[0014] When the distance between the pedestrian and the pillar is no greater than the third predetermined distance, the identification unit is activated. If the identification unit verifies the pedestrian's identity and passes through, the alarm unit stops sounding and pulls the rope to raise the pillar to the second predetermined height for the pedestrian to pass through.

[0015] If, within a preset time after the distance between the pedestrian and the pillar is no greater than the third predetermined distance, the identification unit fails to verify the pedestrian's identity, the alarm unit will issue a level three alarm.

[0016] As a preferred embodiment of the present invention, the column is provided with a motor for driving the pull rope to rise;

[0017] After the identification unit verifies the pedestrian's identity, the motor drives the rope to rise to the second preset height for the pedestrian to pass through.

[0018] As a preferred embodiment of the present invention, a controller is also provided on the column, and the motor, detection unit, alarm unit and identification unit are all electrically connected to the controller.

[0019] As a preferred embodiment of the present invention, the alarm unit includes an alarm horn disposed on the column and an LED light disposed on the pull rope;

[0020] When the alarm department issues a Level 1 alarm, the LED lights will flash;

[0021] When the alarm department issues a level two alarm, the LED lights flash and the alarm horn sounds an audio alarm.

[0022] When the alarm department issues a level 3 alarm, the LED lights flash, the alarm horn sounds an audio alarm, and the alarm department sends an alarm message to the platform control room.

[0023] As a preferred embodiment of the present invention, the detection unit includes a first detector and a second detector;

[0024] When the detection unit detects the distance to a pedestrian, it obtains the distance between the pedestrian and the pillar through the first detector and the distance between the pedestrian and the pillar through the second detector.

[0025] As a preferred embodiment of the present invention, the first detector is a millimeter-wave radar, and the first detector is oriented perpendicular to the extension direction of the pull rope; the second detector is a laser rangefinder, and the angle between the orientation of the second detector and the extension direction of the pull rope is less than 90°.

[0026] When the detection unit detects the distance to a pedestrian, the first detector directly obtains the distance between the pedestrian and the first detector, which is used as the distance between the pedestrian and the post. The first detector calculates the distance between the pedestrian and the pull rope by obtaining the distance between the pedestrian and the second detector and the angle between the second detector and the extension direction of the pull rope.

[0027] As a preferred embodiment of the present invention, there are multiple second detectors, and the angles between the multiple second detectors and the extension direction of the pull rope are all different.

[0028] As a preferred embodiment of the present invention, the first predetermined distance is greater than the second predetermined distance;

[0029] Based on the platform area and platform level, a first predetermined distance and a second predetermined distance are generated.

[0030] As a preferred embodiment of the present invention, the third predetermined distance is smaller than the second predetermined distance;

[0031] Based on the recognition distance of the recognition unit, a third predetermined distance is generated.

[0032] The beneficial effects of the end intrusion identification method of the present invention are as follows: setting up a security door at the end of the platform effectively protects the end of the platform from intrusion, effectively blocks malicious intrusion, and provides different intrusion alarms according to the pedestrian's approach position and distance, ensuring safe identification of intrusion at the end of the platform.

[0041] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0042] In the following description, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The following description provides multiple embodiments of this application, which can be substituted or combined with each other. Therefore, this application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then this application should also be considered to include embodiments containing one or more other possible combinations of A, B, C, and D, even if such embodiments are not explicitly described in the following text.

[0043] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the described elements without departing from the scope of this application. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.

[0044] Example 1: As Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of an end-intrusion identification method according to the present invention, and is only one embodiment of the present invention. An end-intrusion identification method is used for an end-intrusion identification structure. The structure includes a plurality of columns 1 disposed at the end of a platform 6 and an end safety door formed by a controllable lifting and lowering pull rope 2 disposed between two adjacent columns 1. The end safety door is located at the longitudinal end of a platform safety door for boarding and alighting passengers and is perpendicularly connected to the platform safety door to form a rectangular closed safety door. The pull rope of the end safety door is normally closed at a first preset height. The structure also includes a detection unit for detecting pedestrian approach and an alarm unit for issuing an intrusion alarm, including a detection unit 3 for detecting pedestrian approach and an alarm unit 4 for issuing an intrusion alarm.

[0045] In this invention, an end safety gate is directly installed at the end of platform 6. The safety gate is a rope-operated safety gate located at the end of the platform, formed by multiple uprights 1 and pull ropes 2 connecting adjacent uprights 1. It should be noted that many platforms now already have platform safety gates on both sides for passengers to board and alight. These platform safety gates prevent pedestrians from jumping off the platform from the side. The structure of the platform safety gate can adopt the design described in Chinese invention patent CN118062060A. Platform safety gates also have multiple uprights; we directly use the uprights at the very end of the platform safety gate as the uprights for the end safety gate. Generally, if the platform width does not exceed 10 meters, only two uprights 1 and a set of pull ropes 2 are needed to form the end safety gate. These two uprights 1 can be the very end uprights of the platform safety gates on both sides of the platform, as shown in the reference. Figure 2 Platform 6 is a long rectangular structure. Platform safety doors are installed along the long side of platform 6, and end safety doors are installed at the short side. These end safety doors are perpendicularly connected to the platform safety doors, forming a closed rectangular safety gate system. All pedestrians arriving at the platform via the overpass or underpass are confined within this rectangular closed safety gate area and cannot intrude outside the platform. Figure 2 As shown.

[0046] To further explain, on platform 6, the platform safety gate consists of a column and a rope connecting two columns forming a gate body. Several such gate bodies form a platform safety gate. The platform safety gate is located on the side of the platform to protect the side edge of the platform (in reality, the platform safety gate is a certain distance from the platform edge), preventing pedestrians from entering the train tracks when trains enter or leave the station. Similarly, the end safety gate consists of a column 1 and a rope 2 connecting two columns forming a gate body with the same structure. Several such gate bodies form an end safety gate, located at the end of platform 6 to protect the end of the platform (in reality, the end safety gate is a certain distance from the end of the platform, and there is a sloping area on the outside of the end safety gate). This prevents pedestrians on the platform from reaching the end of the platform and entering the train tracks, and also prevents pedestrians from going around to the outside of the closed platform safety gate from the end of platform 6. The risk of being sucked off the platform when trains enter or leave the station at high speed can also be effectively avoided.

[0047] In other words, the main structures of the end safety doors and the platform safety doors are the same and can adopt the same structure. For example, the safety door structure design described in Chinese invention patent CN118062060A uses a motor to drive a rope for lifting and lowering, providing protection for the sides and ends of the platform. Figure 4 , 5 As shown in Figure 6 ( Figure 4 , 5The reference numerals in the appendix 6 are only those in Chinese invention patent CN118062060A and are unrelated to the reference numerals in this invention, making installation simpler.

[0048] Of course, when the platform screen doors are lowered by the pull rope, the platform screen doors are closed and passengers cannot pass through. Only when the train enters or leaves the station will the pull rope be raised and the platform screen doors be opened, allowing passengers to board and alight the train through the platform screen doors and the train's carriage doors.

[0049] Additionally, at the end safety gate, the pull rope is usually kept in a lowered, normally closed state, and the end safety gate is closed, preventing passengers from passing through. Only when staff need to pass through, patrol the line, or perform equipment maintenance will the pull rope be raised, the end safety gate be opened, and staff pass under the pull rope.

[0050] It is important to note that when there are people standing outside the platform screen doors, the platform screen doors should be opened or stopped closing to allow them to return to the enclosed space.

[0051] And when someone approaches from the inside of the end safety door, the end safety door closes or stops rising, that is, to prevent pedestrians from entering the end of the platform, the end safety door is closed or remains closed;

[0052] Furthermore, if there are people lingering outside the platform safety doors and the platform safety doors are abnormally unable to be opened, the end safety doors can be opened to increase the escape route. Opening the end safety doors allows people staying outside the enclosed space to withdraw back into the enclosed space.

[0053] In summary, by installing rope 2 between the columns at the ends of the existing platform safety gate structures on both sides of the platform, the end intrusion protection is achieved, and the end safety gate and the platform safety gate form a closed protection.

[0054] Moreover, the pull rope of the end safety gate is in a normally closed state at a first preset height. Generally speaking, multiple pull ropes are arranged in parallel, with the shortest pull rope about 0.2 meters from the platform ground and the tallest pull rope about 1.6 meters from the ground. The distance between two adjacent pull ropes is about 0.2 meters, which is enough to prevent pedestrians from crossing. This initial state is the first preset height.

[0055] When the end safety gate is opened, the pull rope needs to be driven to rise to the second preset height. At this time, the shortest pull rope rises to about 1.8 meters above the ground to facilitate the passage of workers.

[0056] At this end safety gate, there is also a detection unit 3 and an alarm unit 4. The detection unit 3 can detect the distance of pedestrians from the safety gate (specifically, the distance between the pedestrian and the pillar 1 and the distance between the pedestrian and the rope 2). Once a pedestrian gets too close and is identified as an illegal intruder, the alarm unit 4 needs to sound an alarm, firstly to scare away the illegal intruder, and secondly to remind the surrounding staff to persuade them to leave.

[0057] The method includes the following steps:

[0058] When the detection unit detects that the distance between the pedestrian and the rope is less than the first predetermined distance and the distance between the pedestrian and the post is not greater than the distance between the pedestrian and the rope, the alarm unit will not issue an alarm.

[0059] In fact, the key data here are two: "distance L1 between the pedestrian and the post" and "distance L2 between the pedestrian and the rope". Since the safety gate is formed by two posts and the rope between them, the posts can be considered as points, while the rope is a line. The distance between the pedestrian and the post is the straight-line distance. However, the rope cannot be calculated directly. It is necessary to draw a perpendicular line from the pedestrian's point to the rope. This perpendicular line is the distance between the pedestrian and the rope. In actual application, the posts are raised, and the rope cannot be designed to rest directly against the surface of the post. Therefore, when the pedestrian is directly in front of the post, the distance L1 between the pedestrian and the post is slightly smaller than the distance L2 between the pedestrian and the rope. After introducing trigonometric functions for calculation, within a very small fan-shaped area directly in front of the post, the distance L1 between the pedestrian and the post is no greater than the distance L2 between the pedestrian and the rope.

[0060] Meanwhile, since the pull rope 2 is quite long, the device for opening the end safety door can only be installed on the column 1. If a pedestrian approaches directly in front of the pull rope 2, the end safety door cannot be opened. Anyone who has received basic training knows that they should approach the column 1 to open the door and then pass through the pull rope. Therefore, if a pedestrian directly intrudes in front of the pull rope 2, it is definitely an illegal intrusion. Conversely, if the approach is legal, the legal person will approach the column 1 directly and will approach the end safety door in a very small fan-shaped area directly in front of the column 1.

[0061] Therefore, when the second detector senses a pedestrian approaching in front of the rope, and the distance L2 between the pedestrian and the rope is less than the first predetermined distance, it means that the pedestrian has entered the intrusion detection range of the detection unit 3. If the distance L1 between the pedestrian and the pillar is not greater than the distance L2 between the pedestrian and the rope, it means that the pedestrian is located in a very small fan-shaped area directly in front of the pillar and is actively approaching the pillar 1. In this case, the pedestrian is temporarily deemed not to have any intention of illegal intrusion, and the alarm unit will not issue an alarm.

[0062] When the detection unit detects that the distance between the pedestrian and the rope is less than the first predetermined distance and the distance between the pedestrian and the post is greater than the distance between the pedestrian and the rope, the alarm unit issues a level one alarm.

[0063] Similarly, when the second detector senses a pedestrian approaching in front of the rope, and the distance L2 between the pedestrian and the rope is less than the first predetermined distance, it means that the pedestrian has entered the intrusion detection range of the detection unit 3. However, if the distance L1 between the pedestrian and the pillar is greater than the distance L2 between the pedestrian and the rope, it means that the pedestrian has left a very small fan-shaped area directly in front of the pillar. That is, the pedestrian is not directly approaching the pillar 1, but illegally intruding into the position of the rope 2. There may be a possibility of maliciously climbing over the rope 2. That is, there is an intention to illegally intrude, and the alarm unit needs to issue an alarm.

[0064] At this point, only a Level 1 alarm is issued, since the initial predetermined distance is still quite large, and there is a possibility that people waiting on the platform may accidentally enter. Issuing a Level 1 alarm at this time reminds waiting passengers that this place is dangerous and should not be entered, and reminds pedestrians to evacuate voluntarily. Conversely, if the pedestrian is a staff member, when a Level 1 alarm is issued, it can also remind the staff member to approach only a very small fan-shaped area directly in front of the pillar before approaching, and not to make any misoperations (approach in an incorrect way).

[0065] When the detection unit detects that the distance between the pedestrian and the rope is less than the second predetermined distance and the distance between the pedestrian and the post is greater than the third predetermined distance, the alarm unit issues a level two alarm.

[0066] When a pedestrian approaches the rope safety gate further until the distance L2 between the pedestrian and the rope is less than the second predetermined distance and the first predetermined distance is greater than the second predetermined distance, it indicates that the pedestrian is very close to the rope gate and there is a possibility of climbing over it in a short time. If the distance between the pedestrian and the pillar is not greater than the third predetermined distance, it can be understood that the staff is attempting to legally open the end safety gate and no alarm needs to be issued. Conversely, if the distance between the pedestrian and the pillar is greater than the third predetermined distance, it can be understood that the staff is not directly approaching the pillar 1, but is not far in front of the rope 2 and too far away from the pillar 1. That is, the staff is not attempting to legally open the end safety gate. At this time, it is directly identified as illegal intrusion by the pedestrian and there is a risk of malicious climbing over. The alarm level needs to be increased and an alarm should be issued directly in the form of a level two alarm. This is to deter illegal intruders and to remind the staff on the platform to arrive and persuade the illegal intruders to leave.

[0067] Generally, a first predetermined distance and a second predetermined distance are generated based on the platform area and platform level.

[0068] This invention provides an end-point intrusion identification method, which sets up a security door at the end of the platform to effectively protect the end of the platform from intrusion, effectively block malicious intrusion, and issue different intrusion alarms based on the pedestrian's approach position and distance, ensuring safe identification of intrusions at the end of the platform.

[0069] Example 2, still as Figures 1 to 3 As shown, this is only one embodiment of the present invention. Based on the first embodiment, in the end intrusion identification method of the present invention, the column is further provided with an identification part 5.

[0070] The identification unit 5 can identify whether the approaching pedestrian is a legitimate person, i.e., a staff member. The identification unit 5 can be a facial recognition device, a combination lock, a fingerprint lock, etc. Conversely, if the approaching pedestrian is not a staff member or other specially authorized person to pass through, it is recorded as an illegal intrusion, and the alarm unit 4 will sound an alarm to drive the illegal person away from the end security door.

[0071] In this invention, until the distance L2 between the pedestrian and the pull rope is less than the second predetermined distance, it indicates that the pedestrian is very close to the pull rope gate and there is a possibility of climbing over it in a short time. If the distance between the pedestrian and the post is not greater than the third predetermined distance, it can be understood that the staff is trying to legally open the end safety gate. There is no need to issue an alarm and the identification unit 5 is activated. The identification unit 5 identifies and verifies the identity of the pedestrian. If the identification unit verifies that the pedestrian's identity has passed, the alarm unit stops the alarm and opens the end safety gate. The pull rope is raised to the second preset height for the pedestrian to pass through.

[0072] Conversely, if the pedestrian identification unit fails to verify the pedestrian's identity within a preset time after the distance between the pedestrian and the pillar is no greater than the third predetermined distance, the alarm unit will issue a level three alarm. In other words, if the pedestrian fails to successfully pass the pedestrian identity verification once after the preset time has elapsed after the distance L1 between the pedestrian and the pillar is less than the third predetermined distance, then there is a risk of malicious intrusion and an attempt to confuse the verification process. At this time, the alarm will be upgraded again to a level three alarm, which will not only notify the platform but also alert the control room behind the platform, and notify the high-speed rail police to conduct patrols.

[0073] It should be noted that the third predetermined distance is not less than the second predetermined distance; the third predetermined distance is generated based on the identification distance of the identification unit, and in fact, the third predetermined distance is the farthest distance at which the identification unit can perform personnel identification.

[0074] Of course, when generating the second preset distance, the third preset distance must also be considered. That is, the second preset distance cannot be greater than the third preset distance. For example, if the maximum distance at which the identification unit can identify a person is 1.5 meters, then the second preset distance can be appropriately set to 1.2 meters. In other words, if a legitimate person approaches the pillar vertically, they will first enter the space where the distance L1 between the pedestrian and the pillar is less than the third preset distance, and then reach the space where the distance L2 between the pedestrian and the rope is less than the second preset distance. At this time, the alarm unit will not trigger a second-level alarm.

[0075] Furthermore, the first predetermined distance must be greater than the third predetermined distance. Obviously, when a legitimate person approaches the pillar, there will be a moment when the person's distance from the rope is just less than the first predetermined distance, but the distance between the pedestrian and the pillar is still greater than the third predetermined distance. At this point, a level one alarm will still be triggered. However, within a very short time, the legitimate person can pass the verification by the identification unit, thus deactivating the alarm. This very short time also serves as a recording and alert process, recording that a worker has approached and legitimately entered, and alerting other workers that a worker has approached and legitimately entered the end safety gate.

[0076] The identification unit 5 can be active identification, which is active monitoring and identification, such as facial recognition, iris recognition, etc.; or it can be passive identification, which is waiting for pedestrians to enter a password or press a fingerprint, etc.; if the identification is successful, it means that the person is legitimate and can pass through; otherwise, if the identification fails, it means that the person is illegitimate and cannot pass through the security gate.

[0077] Correspondingly, a motor for driving the pull rope 2 to rise is provided on the column 1;

[0078] After the identification unit verifies the pedestrian's identity, the motor drives the rope to rise to the second preset height so that the pedestrian can pass through.

[0079] Furthermore, a controller is also provided on the column, and the motor, detection unit 3, alarm unit 4, and identification unit 5 are all electrically connected to the controller.

[0080] Example 3, still as Figures 1 to 3 As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, in an end-intrusion identification method of the present invention, the alarm unit 4 includes an alarm horn 41 disposed on the column 1 and an LED light 42 disposed on the pull rope 2.

[0081] When the alarm department issues a Level 1 alarm, the LED lights will flash;

[0082] When the alarm department issues a level two alarm, the LED lights flash and the alarm horn sounds an audio alarm.

[0083] When the alarm department issues a level 3 alarm, the LED lights flash, the alarm horn sounds an audio alarm, and the alarm department sends an alarm message to the platform control room.

[0084] Furthermore, after any alarm is issued by the alarm unit, the anti-crossing procedure of the end safety door needs to be performed, specifically as follows:

[0085] The system determines whether a pedestrian is touching the pull rope and acquires real-time data on the pull rope being touched. If a pedestrian is touching the pull rope, the pull rope is raised to a third preset height to prevent the pedestrian from climbing over. Conversely, if no pedestrian is touching the pull rope, the pull rope of the end safety gate remains in a normally closed state at a first preset height.

[0086] When any alarm is issued by the alarm department, it is determined that there is an illegal approach by the personnel and a possibility of illegal intrusion into the end of the platform. While maintaining the current level of alarm, the pull rope of the end safety door is maintained (or lowered from the open state) to the first preset height. It is also necessary to further prevent malicious intrusion by unauthorized personnel. The only possibility of malicious intrusion is to climb over the top pull rope or spread the two pull ropes and crawl between them. In any case, they will touch the pull rope.

[0087] It's important to explain here that when the end safety gate is closed, the topmost rope is at least 1.6 meters above the ground. We assume the pedestrians climbing over are ordinary people, not high jumpers, and cannot climb over the rope safety gate without touching the ropes. Furthermore, the distance between two adjacent ropes is generally between 20cm and 25cm. Without spreading the two ropes apart, it's impossible for an average person to pass between them. Moreover, due to the long span of the ropes, they are kept taut during the initial installation to prevent pedestrians from spreading them apart. To spread the two ropes apart manually requires considerable pulling force, which inevitably involves the entire palm touching and gripping the ropes and then applying force (unless using special equipment).

[0088] Therefore, if a pedestrian touches the rope, there is a direct risk of malicious intrusion, and the high-speed rail police will be notified to conduct a patrol.

[0089] Since pedestrians have illegally entered the rope gate at this time, to prevent them from crossing, when a pedestrian prepares to cross the rope gate, they will inevitably climb over one of the ropes (the lower of the two ropes). This process inevitably causes the rope to be touched and subjected to downward pressure. The pressure sensor installed at the hook 21 at the end of the rope can detect which rope has been touched by the intruder. The rope will then rise to a third preset height to prevent intrusion. When the rope rises from the first preset height to the third preset height, it will lift and block the legs of the pedestrian preparing to cross (crotch block), thus reducing the possibility of the pedestrian crossing in a short time. At this time, the staff will have enough time to arrive and persuade the intruder to leave.

[0090] Ideally, the number of the pull rope 2 that the pedestrian is in contact with should be identified. When the pedestrian is crossing, the pull rope 2 with that number should be raised to a third preset height to increase the difficulty for unauthorized intruders to climb over, making it impossible for them to do so. The third preset height is generally 10cm to 15cm. This not only helps to stop the pedestrian from crossing along with the pull rope above (spaced a few centimeters apart), but also the distance between the pull rope with that number and the pull rope below it is not large, remaining at about 30cm, so the pedestrian cannot cross directly. Alternatively, several pull ropes below the pull rope with that number can also be raised to prevent pedestrians from crossing. For example, the first pull rope below it could be raised by 9cm, the second pull rope below it by 6cm, and the third pull rope below it by 3cm. In this way, the change in the distance between each pair of pull ropes in the space below the pull rope that stops the pedestrian will be smaller.

[0091] Example 4, still as Figures 1 to 3 As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, in the end-intrusion identification method of the present invention, the detection unit 3 includes a first detector 31 and a second detector 32.

[0092] When the detection unit detects the distance to a pedestrian, it obtains the distance between the pedestrian and the pillar through the first detector and the distance between the pedestrian and the pillar through the second detector.

[0093] Furthermore, the first detector 31 is a millimeter-wave radar, and the first detector 31 is oriented perpendicular to the extension direction of the pull rope 2; the second detector 32 is a laser rangefinder, and the second detector 32 is located on the side of the column 1 close to the pull rope 2, and the angle between the orientation of the second detector 32 and the extension direction of the pull rope 2 is less than 90°.

[0094] When the detection unit detects the distance to a pedestrian, the first detector directly obtains the distance between the pedestrian and the first detector, which is used as the distance between the pedestrian and the post. The first detector calculates the distance between the pedestrian and the pull rope by obtaining the distance between the pedestrian and the second detector and the angle between the second detector and the extension direction of the pull rope.

[0095] Since the pull rope 2 is quite long, about 10 meters, millimeter-wave radar cannot detect such a long distance. Therefore, a laser rangefinder is directly installed on the side of the column 1 closest to the pull rope 2. Of course, the second detector 32 is inclined and extends forward of the pull rope 2. When no one is near the pull rope 2, the distance measurement value of the second detector 32 is a safe value; once someone approaches the pull rope 2, the distance measurement value of the second detector 32 will decrease, which indicates that someone is approaching the pull rope 2.

[0096] In this invention, there are multiple second detectors 32, and the angles between the multiple second detectors 32 and the extension direction of the pull rope 2 are all different. By using different second detectors 32, the approach of pedestrians can be detected without blind spots, and by using multiple second detectors, the distance between pedestrians and pull ropes can be known more accurately.

[0097] This invention provides an end-point intrusion identification method, which sets up a security door at the end of the platform to effectively protect the end of the platform from intrusion, effectively block malicious intrusion, and issue different intrusion alarms based on the pedestrian's approach position and distance, ensuring safe identification of intrusions at the end of the platform.

[0098] This invention is not limited to the specific embodiments described above, and various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made to the above embodiments based on the technical essence of this invention should be included within the scope of protection of this invention.
