Description

Technical Field

[0001] This invention relates to the field of escalator operation safety technology, and in particular to a remote monitoring method for escalator operation safety. Background Technology

[0002] Escalators are convenient public facilities that facilitate passenger movement, widely used in high-traffic areas such as subways, airports, train stations, and shopping malls. However, due to the complex usage scenarios and weak safety awareness among passengers, accidents such as falls on escalators, especially involving the elderly or children, and passengers' belongings rolling off, are frequent. Traditional emergency response methods typically involve staff pressing the emergency stop button at the end of the escalator to stop it. However, this method is not only untimely but also fails to prevent people or items from continuing to fall, and its timeliness and safety need improvement. Therefore, there is an urgent need for a remote monitoring method for escalator operation safety that can prevent people or items from falling abnormally, improve escalator operation safety, and enhance the timeliness of handling abnormal situations. Summary of the Invention

[0003] This invention provides a remote monitoring method for escalator operation safety, which can prevent people or objects from falling abnormally on the escalator, improve the safety of escalator operation, and enhance the timeliness of handling abnormal situations.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A method for remote monitoring of escalator operation safety includes the following steps:

[0006] S100, acquire escalator image;

[0007] S200: Based on the escalator image, analyze whether there is any abnormal falling of the target object above the escalator. If not, the process ends; if so, proceed to S300.

[0008] S300: Analyze the location of the target object based on the escalator image;

[0009] S400, based on the location of the target object, controls the activation of the blocking device installed on the handrail wall panel in the escalator to block the target object.

[0010] The principle and advantages of this invention are as follows: By capturing escalator images, the passenger riding situation on the escalator can be obtained, thereby analyzing whether there is an abnormal fall of a target object (passenger or items carried by passengers) on the escalator; when an abnormal fall is detected, the blocking device installed on the handrail and wall panel of the escalator is activated according to the position of the target object, promptly blocking the falling target object and preventing it from rolling further down the escalator, thus protecting the safety of the target object itself and preventing passengers below from being knocked down by the target object and causing a larger safety accident. Using this solution, abnormally falling personnel or items on the escalator can be blocked, improving the safety of escalator operation and the timeliness of handling abnormal situations.

[0011] Furthermore, the S400 includes:

[0012] S401, Based on the location of the target object, the position that is at a preset blocking distance in the horizontal direction from the target object and is close to the bottom of the escalator is set as the target blocking position;

[0013] S402, control the movement of the blocking device on the handrail wall panel to the target blocking position.

[0014] Beneficial effect: During the activation of the blocking device, the target object may fall down the escalator steps. Therefore, blocking the target object at a predetermined blocking distance near the bottom of the escalator will improve the success rate of blocking.

[0015] Furthermore, the handrail guard plate is provided with a slide rail parallel to the handrail in the escalator;

[0016] The blocking device includes a sliding base and a blocking bar, one end of which is rotatably connected to the sliding base;

[0017] The initial position of the barrier bar is perpendicular to the horizontal plane;

[0018] The slide block is slidably engaged on the slide rail; the blocking device moves to the target blocking position by the movement of the slide block on the slide rail.

[0019] The S400 also includes:

[0020] S403, control the barrier arm to rotate until it is parallel to the horizontal plane.

[0021] Beneficial effects: The movement of the blocking device on the escalator is achieved through the cooperation of the sliding seat and the sliding rail. Using this solution, only one blocking device is needed per escalator to block objects at multiple locations, reducing practical application costs. Initially, the blocking bar is perpendicular to the horizontal plane and installed on the handrail panels on both sides of the steps, thus not affecting passengers on the escalator. When there is no need to block falling objects, the blocking bar is rotated to be parallel to the horizontal plane, preventing the falling object from continuing to fall and improving safety during escalator operation.

[0022] Furthermore, the blocking device also includes a motor, a rotating shaft, bearings, and a rotating sleeve;

[0023] The motor is fixedly mounted on the slide, one end of the rotating shaft is connected to the output end of the motor, and the other end is rotatably mounted in the slide through a bearing;

[0024] The rotating sleeve is fixedly sleeved on the rotating shaft, and the blocking rod is fixedly connected to the rotating sleeve. The rotating shaft of the motor drives the blocking rod, which is fixedly connected to the rotating sleeve, to rotate.

[0025] Beneficial effects: The rotating shaft is connected to the output end of the motor, the rotating sleeve is fixedly sleeved on the rotating shaft, and the blocking rod is fixedly connected to the rotating sleeve. Thus, the rotating shaft can be driven to rotate by the motor, which in turn drives the blocking rod fixedly connected to the rotating sleeve to rotate.

[0026] Furthermore, the outer peripheral wall of the slide is provided with a clearance groove for the barrier bar to extend out and rotate under the drive of the rotating shaft.

[0027] Beneficial effect: A clearance groove is opened on the outer peripheral wall of the slide to allow the blocking bar to extend and rotate under the drive of the rotating shaft.

[0028] Furthermore, the slide rail is located at the bottom of the handrail wall panel, and the bottom end of the barrier bar is rotatably connected to the slide block.

[0029] Beneficial effects: Since the size of the target object is variable, if the height of the barrier bar is set too high, the target object may continue to fall from below the barrier bar. Therefore, in this solution, the slide rail is set at the bottom of the handrail wall panel, and the bottom end of the barrier bar is rotatably connected to the slide base, which can improve the success rate of blocking the target object when the barrier bar is extended.

[0030] Furthermore, the barrier bar includes a base plate and a top plate, with the base plate parallel to the top plate;

[0031] One end of the base plate is fixedly connected to the rotating sleeve;

[0032] An electric telescopic rod is provided on the base plate, and the top plate is fixedly connected to the top end of the electric telescopic rod; a flexible barrier net is provided between the base plate and the top plate;

[0033] The S400 also includes:

[0034] S404 controls the electric telescopic rod to switch from the retracted state to the extended state.

[0035] Beneficial effects: After the barrier bar is extended, the electric telescopic bar changes from a retracted state to an extended state, thereby opening the flexible barrier net between the two and improving the barrier effect.

[0036] Furthermore, the extension and retraction direction of the electric telescopic rod is perpendicular to the horizontal plane.

[0037] Beneficial effects: The telescopic pole extends and retracts perpendicular to the horizontal plane. Compared to being inclined to the horizontal plane, it has a larger interception area in the vertical direction, thus improving the interception effect.

[0038] Furthermore, it also includes:

[0039] S500 generates an error message and stops the escalator.

[0040] Beneficial effects: By providing anomaly alerts, management personnel can be remotely notified to promptly go to the escalator location to handle the anomaly; at the same time, the escalator can be stopped to prevent the escalation of safety accidents. Attached Figure Description

[0049] Example 1:

[0050] A method for remote monitoring of escalator operation safety, such as Figure 1 As shown, it includes the following steps:

[0051] S100, Acquire escalator images; In this embodiment, a monitoring probe is used to acquire escalator images to achieve remote monitoring of the escalator's operation.

[0052] S200: Based on the escalator image, analyze whether there is any abnormal falling of the target object above the escalator. If not, the process ends; if so, proceed to S300.

[0053] In this embodiment, the following steps are used to analyze abnormal drop situations:

[0054] S1, Obtain the original image set of abnormal fall behavior;

[0055] S2, label the categories and locations of abnormal falling behaviors in the original image set to generate a labeled image set; the categories include people falling, people rolling downwards, objects falling, and objects rolling downwards;

[0056] S3, Create an object detection model and train the object detection model using the labeled image set;

[0057] S4: Based on the escalator image, generate escalator image frames and input them into the trained target detection model for analysis. Determine whether there is an abnormal fall of a target above the escalator and determine the category of the corresponding abnormal fall behavior. If there is an abnormal fall, execute S300 and lock the target that has experienced the abnormal fall behavior. If there is no abnormal fall, end the process.

[0058] S300, based on the escalator image, analyze the position of the target object; specifically, taking the starting point of the step (below the escalator) as the origin, analyze the horizontal distance between the target object and the origin, and record it as the position of the target object. In this embodiment, the position of the target object is 5 meters away from the origin.

[0059] S400: Based on the location of the target object, the blocking device 3 installed on the handrail wall panel 1 in the escalator is activated to block the target object.

[0060] The S400 includes:

[0061] S401, based on the position of the target object, the position that is horizontally spaced from the target object by a preset blocking distance and is close to the bottom of the escalator is set as the target blocking position; in this embodiment, the preset blocking distance is 1 meter. Since the target object is 5 meters away from the origin, the target blocking position is 4 meters away from the origin. If the distance between the target object and the origin is less than 1 meter, the target blocking position is set as the origin.

[0062] S402, control the movement of the blocking device 3 on the handrail wall panel 1 to the target blocking position.

[0063] Specifically, such as Figure 2 As shown, the handrail guard plate 1 is provided with a slide rail 2 parallel to the handrail in the escalator. The blocking device 3 includes a slide seat 4, a blocking rod 5, a motor 6, a rotating shaft 7, a bearing 8, and a rotating sleeve 9. The slide seat 4 is slidably fitted on the slide rail 2. The blocking device 3 moves to the target blocking position by the movement of the slide seat 4 on the slide rail 2.

[0064] S403, control the barrier arm 5 to rotate from being perpendicular to the horizontal plane to being parallel to the horizontal plane.

[0065] Specifically, one end of the blocking rod 5 is rotatably connected to the slide 4, which is used to change the initial position perpendicular to the horizontal plane to a blocking position parallel to the horizontal plane after the blocking device 3 moves to the target blocking position, so as to achieve the purpose of blocking the target object falling on the escalator.

[0066] In this embodiment, the bottom end of the barrier bar 5 is rotatably connected to the slide block 4, and the slide rail 2 is located at the bottom of the handrail guardrail panel 1. The principle is that, compared to placing the slide rail 2 at the top of the handrail guardrail panel 1 and rotatably connecting the top end of the barrier bar 5 to the slide block 4, rotating the barrier bar 5 to a horizontal position allows for more comprehensive blocking of objects of various sizes (in the latter approach, smaller objects may continue to roll down the escalator from below the barrier bar 5). Therefore, this solution offers better blocking effect and efficiency.

[0067] The motor 6, shaft 7, bearing 8, and rotating sleeve 9 are used to achieve the rotation of the blocking rod 5 relative to the slide block 4. Specifically, as shown... Figure 3 As shown, the motor 6 is fixedly mounted on the slide 4. One end of the rotating shaft 7 is connected to the output end of the motor 6, and the other end is rotatably mounted inside the slide 4 via a bearing 8. The rotating sleeve 9 is fixedly sleeved on the rotating shaft 7, and the blocking rod 5 is fixedly connected to the rotating sleeve 9. The rotating shaft 7 of the motor 6 drives the blocking rod 5, which is fixedly connected to the rotating sleeve 9, to rotate. The outer peripheral wall of the slide 4 has a clearance groove for the blocking rod 5 to extend out and rotate under the drive of the rotating shaft 7.

[0068] Therefore, in the initial state, the barrier bar 5 is perpendicular to the horizontal plane and is set on the handrail wall panels 1 on both sides of the steps, so it will not affect the passengers on the escalator. When there is no need to block it, it will not affect the normal use of the escalator. When it is necessary to block the falling target on the escalator through the barrier device 3, the barrier bar 5 is controlled to rotate to be parallel to the horizontal plane, so that the falling target can be prevented from continuing to fall through the barrier bar 5, thus improving the safety of the escalator during operation.

[0069] The S500 system generates an anomaly alert and stops the escalator. This serves to remotely remind management personnel to promptly proceed to the escalator's location to handle the anomaly; simultaneously, it stops the escalator to prevent the escalation of a safety incident.

[0070] This solution can prevent people or objects from falling abnormally on escalators, improve the safety of escalator operation, and enhance the timeliness of handling abnormal situations.

[0071] Example 2:

[0072] The basic principle of Example 2 is the same as that of Example 1, the difference being that, as Figure 4As shown, the barrier bar 5 includes a base plate 10 and a top plate 11, with the base plate 10 and top plate 11 parallel to each other. One end of the base plate 10 is fixedly connected to a rotating sleeve 9, so that the rotation of the rotating sleeve 9 can drive the rotation of the base plate 10. An electric telescopic rod 12 is provided on the base plate 10, and the top plate 11 is fixedly connected to the top end of the electric telescopic rod 12, so that the top plate 11 can also rotate synchronously under the drive of the base plate 10. A flexible barrier net 13 is provided between the base plate 10 and the top plate 11. When the electric telescopic rod 12 is retracted, the flexible barrier net 13 is not subjected to external force and retracts between the base plate 10 and the top plate 11. When the electric telescopic rod 12 is extended, both ends of the flexible barrier net 13 are subjected to opposite forces from the base plate 10 and the top plate 11, thus being in a stretched state and effectively blocking the target object. In this embodiment, the flexible barrier net 13 is made of rubber.

[0073] S400 also includes S404, which controls the electric telescopic rod 12 to change from a retracted state to an extended state. In this embodiment, the telescopic direction of the electric telescopic rod 12 is perpendicular to the horizontal plane. Compared with being inclined to the horizontal plane, its interception area in the vertical direction is larger, thus improving the interception effect.

[0074] Example 3:

[0075] The basic principle of Example 3 is the same as that of Example 1. The difference is that S100 further includes: analyzing the age of each passenger on the escalator based on the escalator image (obtaining passenger information through facial recognition), and recording each passenger and their accompanying items as a target object; and sorting each passenger and their items according to age; specifically, if the passenger's age is greater than or equal to 80 years old or less than 7 years old, they are placed in the first sequence; if the passenger's age is greater than 70 years old and less than 80 years old, or greater than or equal to 7 years old and less than 14 years old, they are placed in the second sequence; otherwise, they are placed in the third sequence; and the target objects in the same sequence are randomly ordered.

[0076] The slide rail is provided with several reserve positions. In this embodiment, there are a first reserve position and a second reserve position, located at one-third of the total length of the slide rail from the bottom and two-thirds of the total length of the slide rail from the bottom, respectively. S100 further includes: dividing the slide rail into two sections, a lower half and an upper half, with the midpoint at the point half of the total length of the slide rail from the bottom, and setting the first reserve position and the second reserve position in the lower half and the upper half, respectively; analyzing the danger coefficient of the lower half and the upper half of the slide rail based on the escalator image and the sorting results, and moving the blocking device to the corresponding reserve position of the section with the higher danger coefficient.

[0077] The risk factor is calculated as follows: if a passenger is included in the first sequence, add 3 points; if a passenger is included in the second sequence, add 2 points; if a passenger is included in the third sequence, add 0.5 points. The scores of the passengers in the upper and lower sequences are added together to obtain the risk factor.

[0078] This increases the probability that the barrier device can quickly reach the required location, and since it is only divided into upper and lower sections, neither of which is too far from the steps.

[0079] The above are merely embodiments of the present invention. Commonly known structures and characteristics are not described in detail here.

Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention. These should also be considered within the scope of protection of the present invention, and will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
