Description

Technical Field

[0001] The present invention relates to the technical field of platform safety, and in particular to a platform end intrusion safety monitoring 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 a platform end intrusion security monitoring method. SUMMARY

[0006] The present application aims to provide a platform end intrusion safety monitoring method, which sets a safety door at the end of the platform, effectively protects the end of the platform from intrusion, effectively blocks malicious intrusion, and gives different intrusion situation alarms according to the approaching position and distance of pedestrians, thereby ensuring the safety identification of platform end intrusion.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: A platform end intrusion safety monitoring method is used for a platform end intrusion safety monitoring structure, which comprises a plurality of columns arranged at the end of the platform and an end safety door formed by a pull rope arranged between two adjacent columns; the end safety door is located at the longitudinal end of the platform safety door for passengers to get on and off and is arranged perpendicularly to the platform safety door to form a rectangular closed safety door, and further comprises a detection part for detecting the distance of pedestrians, an alarm part for giving an intrusion alarm, and an identification part for verifying the identity of pedestrians. The method comprises the following steps: S1: Real-time acquisition of the distance between pedestrians and columns and the distance between pedestrians and pull ropes by the detection part; S2: Judgment of whether the distance between pedestrians and pull ropes is less than a first preset distance; if yes, step S3 is executed; otherwise, no operation is performed; S3: Judgment of whether the distance between pedestrians and columns is less than a second preset distance within a predetermined time; if yes, step S4 is executed; otherwise, a first-level alarm is given by the alarm part; S4: Judgment of whether the verification of the identity of pedestrians by the identification part is passed; if yes, the pull rope is raised to a first preset height for pedestrians to pass through; otherwise, a second-level alarm is given by the alarm part.

[0008] As a preferred embodiment of the present application, step S5 is executed after the alarm part gives an alarm; S5: Judgment of whether the pedestrians contact the pull rope; if yes, a third-level alarm is given by the alarm part; otherwise, the original alarm level is maintained.

[0022] Embodiment one: as shown in Figs. 1 to 3 Fig. 1 ​This is a schematic diagram of a platform end intrusion safety monitoring method according to the present invention, which is only one embodiment of the present invention. A platform end intrusion safety monitoring method is used for a platform end intrusion safety monitoring structure, which includes a plurality of columns 1 disposed at the ends of a platform 6 and an end safety door formed by a controllably raised and lowered 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 disembarking passengers and is vertically connected to the platform safety door to form a rectangular closed safety door. The end safety door is in a normally closed state at a third preset height. The structure also includes a detection unit 3 for detecting the distance to a pedestrian, an alarm unit 4 for issuing an intrusion alarm, and an identification unit 5 for verifying the identity of the pedestrian. 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. Fig. 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. Fig. 2 shown.

[0023] That is to say, by arranging the pull rope 2 between the upright posts at the ends of the safety door structure on both sides of the existing platform, the end intrusion protection function is achieved.

[0024] Moreover, the pull rope of the end safety door is in a normally closed state at a third preset height. Generally speaking, multiple pull ropes are arranged in parallel, the shortest pull rope is about 0.2 meters from the platform ground, the highest pull rope is about 1.6 meters from the ground, and the distance between two adjacent pull ropes is about 0.2 meters, which is enough to prevent pedestrians from passing through. This initial state is the third preset height.

[0025] 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.

[0026] At this end safety gate, a detection unit 3, an alarm unit 4 and an identification unit 5 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 needs to sound an alarm, firstly to scare away the illegal intruders, and secondly to remind the surrounding staff to persuade them to leave; the identification unit 5 can identify whether the approaching pedestrians are legal persons, that is, staff members. The identification unit 5 can be a facial recognition device, a password lock, a fingerprint lock, etc.; on the contrary, once the approaching pedestrians are not staff members or other special persons allowed to pass through, they are recorded as illegal intrusions, and the alarm unit 4 sounds an alarm to drive the illegal persons away from the end safety gate.

[0027] The method comprises the following steps: S1: The distance between the pedestrian and the column and the distance between the pedestrian and the pull rope are obtained in real time through the detection unit; The end safety doors are usually closed to prevent pedestrians from directly passing through and invading the end of the platform. In addition, they are also required to detect whether there are pedestrians approaching the end of the platform with malicious intent. To do this, the detection unit needs to be activated to obtain the distance L1 between the pedestrian and the column and the distance L2 between the pedestrian and the pull rope in real time.

[0028] In fact, the key data here are two: "the distance between the pedestrian and the column L1" and "the distance between the pedestrian and the pull rope L2". Since the safety door is formed by two columns and the pull rope between the two columns, the column can be regarded as a point, but the pull rope is a line connecting the two points. The distance between the pedestrian and the column is the straight-line distance between the pedestrian point and the column point. However, the pull rope cannot be calculated directly. It is necessary to draw a perpendicular line to the pull rope from the pedestrian point. This perpendicular line is the distance between the pedestrian and the pull rope.

[0029] S2: Determine whether there is a pedestrian whose distance from the pull rope is less than a first preset distance; if so, execute step S3; otherwise, do not execute the operation; When a pedestrian approaches the end safety gate, until the distance between the pedestrian and the pull rope is less than the first preset distance, the distance between the pedestrian and the safety gate is less than the first preset distance. At this time, it is necessary to perform intrusion identification on this pedestrian and execute step S3; on the contrary, the distance between the pedestrian and the end safety gate is large and not less than the first preset distance. It is a normal pedestrian activity space and no intrusion identification is required.

[0030] S3: Determine whether the distance between the pedestrian and the pillar is less than a second preset distance within a predetermined time; if so, execute step S4; otherwise, the alarm unit issues a level 1 alarm; Since the pull rope 2 is relatively long, the equipment and identification part 5 for opening the end pull rope door can and can only be set on the pillar 1. Therefore, if a pedestrian approaches directly in front of the pull rope 2, it is impossible to identify and open the end pull rope door. Therefore, any personnel who have received simple training know that they should approach the pillar 1 to perform the opening operation and then pass the pull rope of the pull rope door. Therefore, if a pedestrian is in the danger range but does not approach the pillar 1, it must be an illegal intrusion; on the contrary, if the approach is legal, the legal person will inevitably approach the pillar 1 directly, and the legal person will approach the end safety door directly in front of the pillar 1.

[0031] If the straight-line distance L1 between the pedestrian and the pillar is less than the second preset distance, it means that the pedestrian is close to the pillar and can interact with the recognition part on the pillar, or the pedestrian has reached the pillar interaction area and has a tendency to interact with the recognition part on the pillar; on the contrary, if the distance L1 between the pedestrian and the pillar is not less than the second preset distance, then the pedestrian is not close to the pillar and cannot interact with the recognition.

[0032] When the pedestrian is less than the first preset distance from the entire end safety door and maintains the first predetermined time, but still does not move in front of the pillar 1 for identification interaction, it means that the pedestrian is an illegal intruder and may have the possibility of maliciously climbing over the rope 2, that is, there is an illegal intrusion intention at this time, and the alarm unit needs to sound an alarm; On the contrary, if the pedestrian reaches the pillar interaction area within the first predetermined time when the distance from the pedestrian to the entire end safety door is less than the first preset distance (the straight-line distance L1 between the pedestrian and the pillar is less than the second preset distance), then pedestrian identity verification is required and step S4 is executed.

[0033] Of course, the first predetermined distance is greater than the second predetermined distance.

[0034] Before executing step S2, a first predetermined distance is generated according to the platform area and the platform level; Before executing step S3, a second predetermined distance is generated according to the recognition distance of the recognition unit. In fact, the second predetermined distance is the farthest distance at which the recognition unit can perform personal identity recognition.

[0035] S4: Determine whether the identification unit verifies the identity of the pedestrian; if so, the pull rope is raised to a first preset height to allow the pedestrian to pass; otherwise, the alarm sounds a second-level alarm.

[0036] When the pedestrian reaches the pillar interaction area (the straight-line distance L1 between the pedestrian and the pillar is less than the second preset distance), the pedestrian's identity is identified and verified. 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 the pedestrian to enter a password or press a fingerprint, etc.; if the identification is passed, it means that the legal person can pass, and the pull rope will rise to the first preset height for the pedestrian to pass through; otherwise, if the identification fails, the pedestrian is an illegal person and cannot pass through the security door.

[0037] Here, after the distance L1 between the pedestrian and the column is less than the second preset distance, and the second preset time has passed, 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 needs to be upgraded to a second-level alarm to increase the alarm intensity, in order to scare away illegal intruders and to remind the staff on the platform to arrive and persuade the illegal intruders to leave.

[0038] Of course, before executing step S4, a first preset height is generated based on the platform location information. Generally speaking, the first preset height is set based on the local average height and 90% height value to ensure that the pull rope will not affect the passage of staff after it is raised to the first preset height, thereby reducing safety hazards.

[0039] The present invention provides a platform end intrusion safety monitoring method, which sets a safety door at the platform end to effectively protect the platform end from intrusion, effectively block malicious intrusion, and issue different intrusion situation alarms according to the pedestrian's approach position and distance, ensuring the safe identification of platform end intrusion.

[0040] Example 2, still as Figs. 1 to 3 The figure is only one embodiment of the present invention. Based on the first embodiment, in a platform end intrusion security monitoring method of the present invention, after the alarm unit issues an alarm, step S5 is executed; S5: Determine whether the pedestrian has touched the pull rope. If so, the alarm unit will issue a level 3 alarm; otherwise, the original alarm level will be maintained.

[0041] When the alarm unit issues a level one alarm in step S3 and a level two alarm in step S4, the approaching person is judged to be an illegal intruder. While processing the current alarm, it is necessary to further prevent malicious intrusion by illegal persons and execute step S5. The only possibility of malicious intrusion is to climb over the top rope or to stretch the two ropes and drill through between the two ropes. In any case, the person will touch the rope (when the end safety door is closed, the top rope is about one and a half meters from the ground. We assume that the pedestrian climbing over is an ordinary person, not a high jumper, and cannot climb over the rope safety door without touching the rope).

[0042] Therefore, once a pedestrian touches the pull rope, the alarm department will upgrade again and issue a level three alarm; that is, there is a risk of malicious intrusion, and a level three alarm will be issued. Not only will notifications be made on the platform, but the control room behind the platform will also be alerted, notifying high-speed rail police and others to conduct patrols.

[0043] In the present invention, when the alarm unit issues a third-level alarm, the pull rope touched by the pedestrian is obtained in real time, and the pull rope is controlled to rise to a second preset height to prevent the pedestrian from climbing over.

[0044] 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. This process inevitably causes the ropes to be touched and subjected to downward pressure. The pressure sensor set at the hook 21 at the end of the rope can sense which rope is touched by the intruder, and the rope will rise to a second preset height to prevent intrusion. It may only rise by a dozen centimeters to the second preset height, which will lift the legs of the pedestrian who is about to cross and jam them (jam the crotch). At this time, the staff will have enough time to arrive and persuade the illegal intruder to leave.

[0045] Preferably, the number of the pull rope 2 touched by the pedestrian is identified, and when the pedestrian crosses over, the pull rope 2 with that number is appropriately raised to a second preset height, thereby increasing the difficulty for illegal intruders to climb over and making it impossible for them to climb over.

[0046] Example 3, still as Figs. 1 to 3 The figure shown is only one embodiment of the present invention. Based on any of the above embodiments, in a platform end intrusion safety monitoring method of the present invention, a controller is provided on the column, and the detection unit 3, the alarm unit 4 and the identification unit 5 are all electrically connected to the controller; a motor for driving the pull rope 2 to rise and fall is provided on the column 1, and the motor is electrically connected to the controller; When the identification unit verifies the identity of a pedestrian passing through, the controller controls the motor to operate so that the pull rope rises to a first preset height for the pedestrian to pass through.

[0047] Furthermore, the alarm unit 4 includes an alarm speaker 41 provided on the pillar 1 and an LED light 42 provided on the pull rope 2; In step S3, when the alarm unit issues a level 1 alarm, the LED light flashes; In step S4, when the alarm unit issues a secondary alarm, the LED light flashes and the alarm speaker issues a voice alarm; In step S5, when the alarm unit issues a level 3 alarm, the LED light flashes, the alarm speaker issues a voice alarm, and the alarm unit sends an alarm message to the platform control room.

[0048] In the present invention, the detection unit 3 includes a first detector 31 and a second detector 32; When executing step S3, the distance between the pedestrian and the pillar is obtained by the first detector; When executing step S2, the distance between the pedestrian and the pillar is obtained by the second detector.

[0049] 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 angle between the direction of the second detector 32 and the extension direction of the pull rope 2 is less than 90°; When executing step S3, the first detector directly obtains the distance between the pedestrian and the first detector as the distance between the pedestrian and the pillar; When executing step S2, the second 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.

[0050] 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.

[0051] 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.

[0052] The present invention provides a platform end intrusion safety monitoring method, which sets a safety door at the platform end to effectively protect the platform end from intrusion, effectively block malicious intrusion, and issue different intrusion situation alarms according to the pedestrian's approach position and distance, ensuring the safe identification of platform end intrusion.

[0053] 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.
