Description

Technical Field

[0001] The present invention relates to the field of platform security technology, and in particular, to a terminal intrusion identification method. Background Art

[0002] Current railway transportation, especially high-speed rail, features high volumes, short departure intervals, and heavy passenger traffic. This leads to crowds gathering on platforms while passengers wait for or board trains, forcing platform staff to expend considerable time and effort maintaining order. In the past, individual passengers frequently entered platform end areas, trespassing through critical areas of the line. This poses a significant personal safety risk to passengers and disrupts normal transportation operations, significantly impacting operational order and causing significant direct and indirect economic losses. To prevent passengers from entering platform end areas, current security measures primarily rely on physical barriers and patrols. This involves installing fences at existing end areas and deploying sufficient personnel for surveillance. This approach is labor-intensive, inefficient, and inefficient, and it lacks 24 / 7 monitoring.

[0003] There is also a technology that installs laser radar video devices at both ends of the station platform for security monitoring. By sensing the approach of people and issuing an alarm, for example, Chinese patent invention patent CN115985028A discloses a railway platform end anti-intrusion monitoring system and method. The laser radar video device can capture images of the target area at the platform end, detect laser radars, and detect and identify personnel identity tags. Then, based on the detection signal, it is determined whether there is a person entering the target area. Based on the identity recognition result, it is determined whether the person in the target area is a whitelisted person. When it is determined that there is a person in the target area and the person is not a whitelisted person, an alarm message is generated. The alarm message is transmitted to the platform server and the station integrated control room through the station's internal dedicated network. At the same time, the person entering the target area is given an audible and visual warning and a subtitle warning, thereby achieving efficient and accurate platform end anti-intrusion monitoring. The above invention can replace the traditional physical prevention and personnel patrol mode, improve the intrusion prevention effect of the platform end, and has high monitoring efficiency and accuracy, can achieve accurate personnel differentiation, and prevent false alarms.

[0004] However, the above-mentioned end-anti-intrusion monitoring design still has the following shortcomings: it can only perform intrusion monitoring, cannot effectively block people who invade the end, cannot effectively prevent malicious intrusion incidents from occurring, cannot identify people close to the end of the platform, and cannot ensure the safety 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 the present invention is to provide an end intrusion identification method, which sets a safety 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 situation alarms according to the approach position and distance of pedestrians, ensuring the safe identification of intrusion at the end of the platform.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A method for identifying an end intrusion, for use with an end intrusion identification structure, comprising a plurality of columns disposed at the end of a platform and an end safety door formed by a controllable lifting rope disposed between two adjacent columns; the end safety door is located at the longitudinal end of a platform safety door for boarding and disembarking passengers and is vertically connected to the platform safety door to form a rectangular closed safety door; the rope of the end safety door is in a normally closed state at a first preset height; the structure also includes a detection unit for detecting an approaching pedestrian and an alarm unit for issuing an intrusion alarm; The method comprises the following steps: When the detection unit detects that the distance between the pedestrian and the pull rope is less than the first predetermined distance and the distance between the pedestrian and the pillar is not greater than the distance between the pedestrian and the pull rope, the alarm unit does not sound an alarm; When the detection unit detects that the distance between the pedestrian and the pull rope is less than the first predetermined distance and the distance between the pedestrian and the pillar is greater than the distance between the pedestrian and the pull rope, the alarm unit issues a first-level alarm; When the detection unit detects that the distance between the pedestrian and the pull rope is less than the second predetermined distance and the distance between the pedestrian and the pillar is greater than the third predetermined distance, the alarm unit issues a secondary alarm.

[0008] As a preferred embodiment of the present invention, the column is further provided with an identification portion; When the distance between the pedestrian and the pillar is no greater than a third predetermined distance, the recognition unit wakes up. If the recognition unit verifies that the pedestrian has passed the identification, the alarm unit stops the alarm and the pull rope rises to a second preset height to allow the pedestrian to pass through. Within a preset time after the distance between the pedestrian and the pillar is no greater than the third predetermined distance, if the identification unit still fails to verify the pedestrian's identity, the alarm unit will issue a third-level alarm.

[0009] As a preferred embodiment of the present invention, the column is provided with a motor for driving the pull rope to rise; After the identification unit verifies the identity of the pedestrian and passes, the motor drives the pull rope to rise to a second preset height for the pedestrian to pass through.

[0010] As a preferred embodiment of the present invention, a controller is further provided on the column, and the motor, detection unit, alarm unit and identification unit are all electrically connected to the controller.

[0011] As a preferred embodiment of the present invention, the alarm unit includes an alarm speaker arranged on the column and an LED light arranged on the pull rope; When the alarm unit issues a level one alarm, the LED light flashes; When the alarm unit issues a secondary alarm, the LED light flashes and the alarm speaker issues a voice alarm; When the alarm department issues a level 3 alarm, the LED light flashes, the alarm speaker issues a voice alarm, and the alarm department sends an alarm message to the platform control room.

[0012] As a preferred embodiment of the present invention, the detection unit includes a first detector and a second detector; When the detection unit detects the distance of a pedestrian, the distance between the pedestrian and the pillar is obtained by the first detector, and the distance between the pedestrian and the pillar is obtained by the second detector.

[0013] As a preferred embodiment of the present invention, the first detector is a millimeter wave radar, and the first detector is arranged perpendicular to the extension direction of the pull rope; the second detector is a laser rangefinder, and the angle between the second detector and the extension direction of the pull rope is less than 90°; When the detection unit detects the distance of a pedestrian, the first detector directly obtains the distance between the pedestrian and the first detector as the distance between the pedestrian and the pillar; 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.

[0014] As a preference of the present invention, there are multiple second detectors, and angles between the multiple second detectors and the extension direction of the pull rope are all different.

[0015] As a preferred embodiment of the present invention, the first predetermined distance is greater than the second predetermined distance; A first predetermined distance and a second predetermined distance are generated according to the platform area and the platform level.

[0016] As a preferred embodiment of the present invention, the third predetermined distance is smaller than the second predetermined distance; A third predetermined distance is generated based on the recognition distance recognized by the recognition unit.

[0017] The beneficial effect of the end intrusion identification method of the present invention is that: a safety door is set at the end of the platform to effectively protect the end of the platform from intrusion, effectively block malicious intrusion, and issue different intrusion situation alarms according to the approach position and distance of pedestrians, ensuring the safe identification of intrusion at the platform end.

[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0020] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application. Different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, even though the embodiment may not be clearly described in the following text.

[0021] 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 elements described without departing from the scope of the present application. Various examples may appropriately omit, replace, or add various processes or components. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted, or combined. In addition, features described in some examples may be combined in other examples.

[0022] Example 1: Figures 1 to 3As shown, Figure 1 This is a schematic diagram of an end intrusion identification method of the present invention, which is only one embodiment of the present invention. An end intrusion identification method is used for an end intrusion identification structure, which includes a plurality of columns 1 arranged at the end of a platform 6 and an end safety door formed by a controllable lifting rope 2 arranged between two adjacent columns 1; the end safety door is located at the longitudinal end of the platform safety door for boarding and disembarking passengers and is vertically connected to the platform safety door to form a rectangular closed safety door; the pull rope of the end safety door is in a normally closed state at a first preset height; the structure also includes a detection unit for detecting the approach of pedestrians and an alarm unit for issuing an intrusion alarm, and further includes a detection unit 3 for detecting the approach of pedestrians and an alarm unit 4 for issuing an intrusion alarm; In the present invention, an end safety door is directly set at the end of the platform 6. The safety door is a rope-drawn safety door located at the end of the platform formed by a plurality of columns 1 and a pull rope 2 connected between two adjacent columns 1; it should be noted that many platforms now have platform safety doors on both sides for getting on and off passengers. The platform safety door is used to prevent pedestrians from jumping off the platform from the side of the platform. The structure of the platform safety door can adopt the structural design described in the Chinese patent invention patent CN118062060A. The platform safety door also has multiple platform door columns. We directly use the platform door columns at the end of the platform safety door as the columns of the end safety door. Generally speaking, the platform width does not exceed 10 meters, then only two columns 1 and a set of pull ropes 2 are needed to form the end safety door, and these two columns 1 can be used as the platform door columns at the end of the platform safety door on both sides of the platform. Figure 2 Platform 6 is a long rectangular structure. Platform safety doors are set on the side (long side) of platform 6, and end safety doors are set at the end (short side) of platform 6. In this way, the end safety doors are vertically connected to the platform safety doors to form a closed safety door of a rectangular structure. All pedestrians who arrive at the platform through the overpass or underground passage are located in the area enclosed by this rectangular closed safety door and cannot invade the outside of the platform. Figure 2 shown.

[0023] It is further explained that on platform 6, a door body is formed by a column and a rope between the two columns in the platform safety door, and several such door bodies form a platform safety door. The platform safety door is arranged on the side of the platform to protect the side edge of the platform (in fact, the platform safety door is still a certain distance away from the edge of the platform) to prevent pedestrians from intruding onto the train track when the train enters and exits the station; similarly, a door body of the same structure is formed by a column 1 and a rope 2 between the two columns 1 in the end safety door, and several such door bodies form an end safety door, which is arranged at the end of the platform 6 to protect the end of the platform (in fact, there is still a certain distance between the end safety door and the end of the platform, and there is a sloping downhill area of ​​the platform outside the end safety door) to prevent pedestrians on the platform from reaching the end of the platform and intruding onto the train track, and to prevent pedestrians from detouring from the end of the platform 6 to reach the outside of the closed platform safety door. The risk of being sucked off the platform when the train enters and exits the station at high speed can also be effectively avoided.

[0024] That is to say, the main structure of the end safety door and the platform safety door is the same, and the same structure can be used, such as the safety door structure design described in the Chinese patent invention patent CN118062060A, which uses a motor to drive the pull rope to move up and down to protect the side and end of the platform. Figure 4 、 5 、6 as shown ( Figure 4 、 5 , 6 are only the reference numerals in the Chinese invention patent CN118062060A and have nothing to do with the reference numerals in the present invention), and the installation is simpler.

[0025] Of course, at the platform safety door, when the rope is lowered, the platform safety door is closed and passengers cannot pass. Only when the train enters or leaves the station, the rope is raised and the platform safety door is opened. Passengers can get on and off the train through the platform safety door and the train compartment door. Also, at the end safety door, under normal circumstances, the pull rope is maintained in a normally closed state, the end safety door is closed, and passengers cannot pass through. Only when staff need to pass, patrol the line or inspect equipment, the pull rope is raised, the end safety door is opened, and the staff passes under the pull rope.

[0026] It should be noted that when there are people stranded outside the platform safety door, the platform safety door should be opened or stopped from closing so that the stranded people can return to the enclosed space; When someone approaches the inside of the end safety door, the end safety door closes or stops rising, that is, in order to prevent pedestrians from intruding into the end of the platform, the end safety door closes or remains closed; Furthermore, when there are people stranded outside the platform safety door and the platform safety door cannot be opened due to an abnormality, the end safety door can be opened to increase the escape route. By opening the end safety door, people staying outside the enclosed space can evacuate through the end safety door to get into the enclosed space.

[0027] In short, by arranging a pull rope 2 between the end columns of the platform safety door structure on both sides of the existing platform, the end intrusion protection is achieved, and the end safety door and the platform safety door are enclosed for closed protection.

[0028] Moreover, the pull ropes of the end safety gates are 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 highest pull rope about 1.6 meters from the ground. The distance between two adjacent pull ropes is about 0.2 meters, which is sufficient to prevent pedestrians from passing through. This initial state is the first preset height. When the end safety door is opened, the pull rope needs to be driven to rise to the second preset height. At this time, the shortest pull rope is raised to about 1.8 meters from the ground to facilitate the passage of staff.

[0029] At this end safety gate, a detection unit 3 and an alarm unit 4 are also provided. The detection unit 3 can detect the distance between the surrounding pedestrians and the safety gate (specifically, the distance between the pedestrians and the pillar 1 and the distance between the pedestrians and the pull rope 2). Once the pedestrians are too close and are identified as illegal intruders, the alarm unit 4 will sound an alarm, which will not only scare away the illegal intruders, but also remind the surrounding staff to persuade them to leave.

[0030] The method comprises the following steps: When the detection unit detects that the distance between the pedestrian and the pull rope is less than the first predetermined distance and the distance between the pedestrian and the pillar is not greater than the distance between the pedestrian and the pull rope, the alarm unit does not sound an alarm; In fact, there are two key data here: "the distance between the pedestrian and the column L1" and "the distance between the pedestrian and the rope L2". Since the safety door is formed by two columns and the rope between the two columns, the column can be regarded as a point, but the rope is a line. The distance between the pedestrian and the column is the straight-line distance, but the rope cannot be calculated directly. It is necessary to draw a perpendicular line to the rope starting from the pedestrian point, and this perpendicular line is the distance between the pedestrian and the rope. In actual application, the column is raised and the rope cannot be designed directly against the surface of the column. Then, when the pedestrian is directly in front of the column, the distance L1 between the pedestrian and the column is slightly smaller than the distance L2 between the pedestrian and the rope. After introducing trigonometric function calculation, in a very small fan-shaped area where the pedestrian is directly in front of the column, the distance L1 between the pedestrian and the column is not greater than the distance L2 between the pedestrian and the rope.

[0031] At the same time, due to the long length of the pull rope 2, the equipment for opening the end safety door can and can only be set on the column 1. Therefore, if a pedestrian approaches directly in front of the pull rope 2, the end safety door cannot be opened. Therefore, any personnel who have received simple training knows that they should approach the column 1 to perform the opening operation and then pass the pull rope of the pull rope door. Therefore, if a pedestrian directly intrudes in front of the pull rope 2, it must be an illegal intrusion; on the contrary, if it is a legal approach, the legal person will inevitably approach the column 1 directly, and the legal person will approach the end safety door in a very small fan-shaped area directly in front of the column 1.

[0032] Therefore, when the second detector senses that a pedestrian is approaching in front of the pull rope, and the distance L2 between the pedestrian and the pull 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 at this time the distance L1 between the pedestrian and the pillar is not greater than the distance L2 between the pedestrian and the pull 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 determined to have no intention of illegal intrusion, and the alarm unit does not issue an alarm.

[0033] When the detection unit detects that the distance between the pedestrian and the pull rope is less than the first predetermined distance and the distance between the pedestrian and the pillar is greater than the distance between the pedestrian and the pull rope, the alarm unit issues a first-level alarm; Similarly, when the second detector senses a pedestrian approaching in front of the pull rope, and the distance L2 between the pedestrian and the pull rope is less than the first predetermined distance, it means that the pedestrian has entered the intrusion detection range of the detector 3. However, if the distance L1 between the pedestrian and the pillar is greater than the distance L2 between the pedestrian and the pull rope, it means that the pedestrian has left a very small fan-shaped area in front of the pillar. In other words, the pedestrian is not approaching the pillar 1 directly, but is illegally intruding into the position of the pull rope 2. There is a possibility that the pedestrian is maliciously climbing over the pull rope 2, that is, there is an illegal intrusion intention, and the alarm unit needs to sound an alarm. At this time, only a level one alarm is issued. After all, the first predetermined distance is still a relatively large distance value, and there is a possibility that people waiting on the platform may mistakenly enter. At this time, a level one alarm is issued to remind waiting passengers that this place is dangerous and cannot be entered, and to remind pedestrians to evacuate actively. On the contrary, if the pedestrian is a staff member, when the level one alarm is issued, it can also remind the staff to reach a very small fan-shaped area directly in front of the column before approaching, and not to make mistakes (approaching in the wrong way).

[0034] When the detection unit detects that the distance between the pedestrian and the pull rope is less than the second predetermined distance and the distance between the pedestrian and the pillar is greater than the third predetermined distance, the alarm unit issues a secondary alarm.

[0035] When the pedestrian approaches the rope-pull 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 means that the pedestrian is very close to the rope-pull gate and there is a possibility of climbing over it in a short time. If the distance between the pedestrian and the column is not greater than the third predetermined distance at this time, it can be understood that the staff is trying to legally open the end safety gate and there is no need to issue an alarm; on the contrary, if the distance between the pedestrian and the column is greater than the third predetermined distance at this time, it can be understood that the staff is not directly approaching the column 1, but is not far in front of the rope 2 and too far away from the column 1, that is, the staff did not try to legally open the end safety gate. At this time, it is directly determined that the pedestrian is illegally intruding and there is a risk of malicious climbing over and invading. It is necessary to increase the alarm level and directly issue an alarm in the form of a second-level alarm, one to scare away illegal intruders, and the other to remind the staff on the platform to arrive and persuade the illegal intruders to leave.

[0036] Generally speaking, the first predetermined distance and the second predetermined distance are generated according to the platform area and the platform level.

[0037] The present invention provides an end intrusion identification method, which sets a safety 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 situation alarms according to the approach position and distance of pedestrians, ensuring the safe identification of intrusion at the platform end.

[0038] Example 2, still as Figures 1 to 3 The figure is only one embodiment of the present invention. Based on the first embodiment, in an end intrusion identification method of the present invention, an identification part 5 is further provided on the column. The recognition unit 5 can identify whether the approaching pedestrian is a legal person, that is, a staff member. The recognition unit 5 can be a facial recognition device, a password lock, a fingerprint lock, etc.; on the contrary, once the approaching pedestrian is not a staff member or other special person allowed 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.

[0039] In the present invention, until the distance L2 between the pedestrian and the pull rope is less than the second predetermined distance, it means that the pedestrian is very close to the pull rope door and there is a possibility of climbing over it in a short time. If the distance between the pedestrian and the column is not greater than the third predetermined distance at this time, it can be understood that the staff is trying to legally open the end safety door, and there is no need to sound an alarm. Instead, the recognition unit 5 is awakened, and the recognition unit 5 recognizes and verifies the identity of the pedestrian. If the recognition unit verifies that the pedestrian's identity is passed, the alarm unit stops the alarm, opens the end safety door, and the pull rope is raised to the second preset height for the pedestrian to pass through. On the contrary, within the preset time after the distance between the pedestrian and the pillar is no more than the third predetermined distance, if the identification unit still fails to verify the pedestrian's identity, the alarm unit will issue a third-level alarm; that is to say, after the distance L1 between the pedestrian and the pillar is less than the third predetermined distance, the preset time has passed and the pedestrian identity verification has not been successfully passed once, then there is a risk of malicious intrusion, and an attempt is made to confuse the verification. At this time, the alarm is upgraded again to a third-level alarm, which notifies not only the people on the platform but also the control room behind the platform, notifying the high-speed rail police and others to conduct patrols.

[0040] It should be noted that the third predetermined distance is not less than the second predetermined distance; the third predetermined distance is generated according to the recognition distance of the recognition unit. In fact, the third predetermined distance is the farthest distance at which the recognition unit can perform personal identity recognition.

[0041] Of course, when the second preset distance is generated, the third preset distance must also be considered, that is, the second preset distance cannot be greater than the third preset distance. For example, the farthest distance at which the recognition unit can identify the identity of a person is 1.5 meters, so the second preset distance is appropriately set to 1.2 meters. That is, if a legitimate person approaches the column vertically, he must first enter the space where the distance L1 between the pedestrian and the column is less than the third preset distance, and then reach the space where the distance L2 between the pedestrian and the pull rope is less than the second preset distance. At this time, the alarm unit will not issue a secondary alarm.

[0042] Furthermore, the first predetermined distance is necessarily greater than the third predetermined distance. Obviously, when a legitimate person approaches a pillar, there will inevitably be a moment when the person's distance from the pull 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. In this case, the first level alarm will still be triggered, but within a very short time, the legitimate person can pass the identification verification and the alarm will be deactivated. This short period of time also serves as a record and reminder process, recording the staff member's approach and legal entry, and reminding other staff members that a staff member has approached the end protection safety door and legally entered.

[0043] The identification unit 5 can be active identification, that is, active monitoring identification, such as facial recognition, pupil recognition, etc.; it can also be passive identification, that is, waiting for pedestrians to enter a password or press a fingerprint, etc.; if the identification is passed, it means that the legal person can pass; otherwise, if the identification fails, it means that the person is an illegal person and cannot pass through the security door.

[0044] Correspondingly, the column 1 is provided with a motor for driving the pull rope 2 to rise; After the identification unit verifies the identity of the pedestrian and passes, the motor drives the pull rope to rise to a second preset height to allow the pedestrian to pass through.

[0045] Furthermore, a controller is provided on the column, and the motor, the detection unit 3, the alarm unit 4 and the identification unit 5 are all electrically connected to the controller.

[0046] Example 3, still as Figures 1 to 3 The figure 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 speaker 41 provided on the column 1 and an LED light 42 provided on the pull rope 2; When the alarm unit issues a level one alarm, the LED light flashes; When the alarm unit issues a secondary alarm, the LED light flashes and the alarm speaker issues a voice alarm; When the alarm department issues a level 3 alarm, the LED light flashes, the alarm speaker issues a voice alarm, and the alarm department sends an alarm message to the platform control room.

[0047] Furthermore, after the alarm unit issues any alarm, it is necessary to perform the anti-crossing steps of the end safety door, specifically: Determine whether a pedestrian has touched the pull rope and obtain the pull rope touched by the pedestrian in real time. If a pedestrian has touched the pull rope, the pull rope is controlled to rise to a third preset height to prevent the pedestrian from climbing over; conversely, if no pedestrian has touched the pull rope, the pull rope of the end safety door remains in a normally closed state at the first preset height.

[0048] When the alarm unit issues any alarm, it is judged that the approaching person has illegally approached and there is 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 illegal personnel from malicious intrusion. The only possibility of malicious intrusion is to climb over the top pull rope, or to stretch the two pull ropes and drill through the two pull ropes. In any case, the person will touch the pull rope.

[0049] What needs to be explained here is that when the end safety gate is closed, the top rope is at least about 1.6 meters from the ground. We assume that the pedestrian who is climbing over is an ordinary person, not a high jumper, and it is impossible for him to climb over the rope safety gate without touching the rope. Moreover, the distance between two adjacent ropes is generally between 20cm and 25cm. If the two ropes are not stretched, ordinary people cannot pass between the two ropes. Furthermore, due to the long span of the ropes, in order to avoid pedestrians stretching the two ropes in the initial installation, the ropes are always in a taut state. If you want to stretch the two ropes manually, a large pulling force is required to stretch them, and this stretching process will inevitably cause the entire palm to contact and hold the rope and then exert force (except when using special equipment).

[0050] Therefore, once a pedestrian touches the pull rope, there is a direct risk of malicious intrusion, and the high-speed rail police and others will be notified to conduct patrols.

[0051] Since a pedestrian is illegally intruding at rope 2 at this time, in order to prevent the pedestrian from crossing, when the pedestrian is about to cross the rope door, he or she will inevitably climb over one of the ropes (the lower one of the two stretched ropes). This process inevitably causes the ropes to be touched and subjected to downward pressure. The pressure sensor provided at the hook 21 at the end of the rope can sense which rope is touched by the intruder. The rope is raised to a third preset height to prevent intrusion. When it is raised from the first preset height to the third preset height, the legs of the pedestrian who is about to cross are lifted and stuck (crotch-locked), thereby reducing the possibility of pedestrians crossing in a short time. At this time, the staff has enough time to arrive and persuade the illegal intruder to leave.

[0052] It is best to identify the number of the rope 2 that the pedestrian touches, and when the pedestrian crosses, the rope 2 with that number is appropriately raised to a third preset height, thereby increasing the difficulty for illegal intruders to climb over and preventing them from climbing over. The third preset height is generally 10cm to 15cm, which can not only block the pedestrian who is about to cross together with the rope above it (the distance between them is more than ten centimeters), but also the distance between the rope with that number and the rope below it is not very large, and is still maintained at about thirty centimeters, so that pedestrians cannot cross directly, or several ropes below the rope with that number are also appropriately raised to prevent pedestrians from crossing, for example, the first rope below it is raised by 9cm, the second rope below it is raised by 6cm, and the third rope below it is raised by 3cm. In this way, in the space below the rope that blocks the pedestrian, the change in the expansion of the distance between each two ropes will be smaller.

[0053] Example 4, still as Figures 1 to 3 The figure 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 detection unit 3 includes a first detector 31 and a second detector 32; When the detection unit detects the distance of a pedestrian, the distance between the pedestrian and the pillar is obtained by the first detector, and the distance between the pedestrian and the pillar is obtained by the second detector.

[0054] Furthermore, the first detector 31 is a millimeter-wave radar, and the first detector 31 is arranged perpendicular to the extension direction of the pull rope 2; the second detector 32 is a laser rangefinder, and the second detector 32 is arranged on the side of the column 1 close to the pull rope 2, and the angle between the direction of the second detector 32 and the extension direction of the pull rope 2 is less than 90°; When the detection unit detects the distance of a pedestrian, the first detector directly obtains the distance between the pedestrian and the first detector as the distance between the pedestrian and the pillar; 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.

[0055] Since the pull rope 2 is relatively long, about 10 meters, the millimeter-wave radar cannot detect such a long distance, so a laser rangefinder is directly set on the side of the column 1 close to the pull rope 2. Of course, the second detector 32 is tilted and extended in front of the pull rope 2. When there is no person approaching in front of the pull rope 2, the ranging value of the second detector 32 is a safe value; once someone approaches in front of the pull rope 2, the ranging value of the second detector 32 will become smaller, which means that someone is approaching in front of the pull rope 2.

[0056] In the present 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 different. Through different second detectors 32, pedestrians approaching can be detected without blind spots, and through multiple second detectors, the distance between pedestrians and the pull rope can be known more accurately.

[0057] The present invention provides an end intrusion identification method, which sets a safety 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 situation alarms according to the approach position and distance of pedestrians, ensuring the safe identification of intrusion at the platform end.

[0058] The present invention is not limited to the above specific embodiments, and various modifications and variations are possible. Any modification, equivalent replacement, improvement, etc. made to the above embodiments based on the technical essence of the present invention shall be included in the scope of protection of the present invention.
