Description

Technical Field

[0001] This utility model relates to the field of escalator safety monitoring technology, and in particular to an escalator early warning device based on video recognition. Background Technology

[0002] Escalators, as widely used vertical transportation equipment in public places, play an important role in transporting people in areas with high traffic such as shopping malls, subway stations, and airports. However, with the increasing frequency of escalator use, their safety hazards are becoming increasingly prominent.

[0003] For example, Chinese patent CN214243409U discloses a safety monitoring and early warning device for subway escalators, including: an escalator, a tread structure installed on the outside of the escalator, a set of handrail structures installed on both the front and rear walls of the escalator, an entrance counting structure installed on the outside of the tread structure, an exit counting structure installed on the outside of the tread structure, a light warning structure installed on the front wall of the tread structure, and an audible warning structure installed on the rear wall of the tread structure; the tread structure includes: an entrance tread and an exit tread.

[0004] Existing escalator safety warning devices are mostly static signs or simple voice prompts. Although most shopping mall escalators are equipped with emergency stop buttons, the escalator cannot provide timely voice reminders or emergency stops when passengers fall backward or play on the escalator due to loss of balance. Unsafe behaviors of passengers during escalation increase the risk of accidents. Escalators cannot provide targeted dynamic warnings based on actual passenger behavior and on-site conditions. To address these issues, a video recognition-based escalator warning device is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an escalator early warning device based on video recognition.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an escalator early warning device based on video recognition, comprising a video recognition mechanism and a prompting mechanism. The video recognition mechanism includes a housing, a power supply device, an infrared sensor, and a main camera. The main camera is fixedly installed on the front side of the housing. A microprocessor, a data storage device, and an image processor are respectively installed inside the housing. Support frames are fixedly installed on both sides of the housing, and a side camera is rotatably installed at one end of each support frame. The prompting mechanism includes a movable arm and a display screen. One side of the display screen is rotatably installed with one end of the movable arm, and alarms are fixedly installed at both ends of the display screen.

[0007] Preferably, the top of the power supply device is fixedly installed to the bottom of the housing, and a mounting base is fixedly installed on the bottom of the power supply device.

[0008] Preferably, the infrared sensor is fixedly installed on the front side of the power supply device, and anti-glare covers are fixedly connected to the front sides of both the main camera and the side camera.

[0009] Preferably, a rotating rod is rotatably mounted at one end of the movable arm, and a mounting post is rotatably mounted at the bottom of the rotating rod.

[0010] Preferably, the bottom of the mounting post is welded to the top of the mounting base, and the display screen is located at the top of the housing.

[0011] Preferably, the power supply device has a connection port on the rear side, and both the main camera and the side camera are connected to the image processor via signal.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the behavior of passengers on the escalator is collected in real time by a main camera and two side cameras. The collected video data is transmitted to an image processor, which decodes and preprocesses the video data in real time. The microprocessor can accurately identify various abnormal situations. By recognizing the posture and movements of the passengers, when it is determined that there is an abnormal situation, a warning signal is immediately sent to the escalator's emergency stop system and the alarm.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides an escalator early warning device based on video recognition, including a video recognition mechanism 1 and a prompting mechanism 2. The video recognition mechanism 1 includes a housing 11, a power supply device 12, an infrared sensor 14, and a main camera 15. The main camera 15 is fixedly installed on the front side of the housing 11. A microprocessor 110, a data storage device 111, and an image processor 112 are respectively installed inside the housing 11. Support frames 16 are fixedly installed on both sides of the housing 11, and a side camera 17 is rotatably installed at one end of the support frame 16. The top of the power supply device 12 is fixedly installed to the bottom of the housing 11, and a mounting base 13 is fixedly installed at the bottom of the power supply device 12. The infrared sensor 14 is fixedly installed on the front side of the power supply device 12. Anti-glare covers 18 are fixedly connected to the front sides of the main camera 15 and the side camera 17. A connection port 19 is opened on the rear side of the power supply device 12. The main camera 15 and the side camera 17 are both signal connected to the image processor 112.

[0023] The specific settings and functions of this embodiment will be described in detail below: Figure 1As shown, the device is installed in the middle of one side of the escalator to ensure that the device can capture 360-degree video of the escalator. When the device is in use, one end of the connecting cable is connected to the power supply and the other end is inserted into the connector 19, so that the power supply device 12 can provide stable power support for the entire device. The microprocessor 110 is connected to the emergency stop system of the escalator. The main camera 15 is facing the middle area of ​​the escalator. One side camera 17 faces the escalator entrance to the middle area, and the other side camera 17 faces the escalator exit to the middle area. The main camera 15 and the two side cameras 17 can capture 360-degree video of the escalator area.

[0024] When the escalator warning device is put into normal operation, the infrared sensor 14 is facing the escalator. When a passenger is on the escalator, when a person enters the detection range of the infrared sensor 14, the infrared signal is blocked. The sensor will send an electrical signal to the control system of the microprocessor 110, and the microprocessor 110 will automatically turn on the device. When there are no pedestrians on the escalator for a long time, the warning device will automatically turn off.

[0025] The main camera 15 and two side cameras 17 collect real-time data on passenger behavior on the escalator (all cameras 15 and 17 use wide-angle lenses to ensure a large monitoring range). The collected video data is transmitted to the image processor 112. The data storage device 111 stores historical video data and analysis results for subsequent querying and statistical analysis, providing data support for escalator maintenance. The image processor 112 performs real-time decoding and preprocessing of the video data to improve data clarity and stability. The microprocessor 110 uses deep learning algorithms... After being trained with a large amount of sample data on escalator operation status and passenger behavior, the system can accurately identify various abnormal situations. By recognizing the posture and movements of passengers, it can determine whether passengers are about to fall backward, play or fight on the escalator, or go against the flow. When the microprocessor 110 determines that an abnormal situation has occurred, it immediately sends a warning signal to the escalator's emergency stop system and the alarm 25. The escalator's emergency stop system will stop the escalator immediately, and the alarm 25 will emit a high-decibel alarm sound after receiving the warning signal to attract the attention of people around and remind passengers to pay attention to safety. It will also notify relevant staff to handle the situation in a timely manner.

[0026] This device uses multiple high-definition cameras to collect real-time video data of the escalator operating area and the passenger area, enabling comprehensive monitoring of escalator operation. By processing and identifying the video data, it can quickly and accurately identify various abnormal situations in passenger behavior, issue timely warning signals, and take emergency stop measures, greatly improving the timeliness and accuracy of warnings and effectively preventing safety accidents.

[0027] Example 2: Figures 1-3As shown, the prompting mechanism 2 includes a movable arm 23 and a display screen 24. One side of the display screen 24 is rotatably mounted to one end of the movable arm 23, and alarms 25 are fixedly mounted on both ends of the display screen 24. A rotating rod 22 is rotatably mounted on one end of the movable arm 23, and a mounting post 21 is rotatably mounted on the bottom of the rotating rod 22. The bottom of the mounting post 21 is welded to the top of the mounting base 13. The display screen 24 is located at the top of the outer casing 11.

[0028] The overall effect of this embodiment is that when the microprocessor 110 determines an abnormal situation, it immediately sends a warning signal to the escalator's emergency stop system and the alarm 25. After receiving the warning signal, the alarm 25 emits a high-decibel alarm sound to attract the attention of people around and remind passengers to pay attention to safety. At the same time, it notifies relevant staff to handle the situation in a timely manner. The display screen 24 can play corresponding animation and voice prompts according to different abnormal situations, such as "Please stand firmly and hold on, do not play or fight on the escalator" and "The escalator has malfunctioned, please leave immediately," providing passengers with clearer safety guidance.

[0029] The usage and working principle of this device: When the escalator early warning device is put into normal operation, the infrared sensor 14 is facing the escalator. When a passenger is on the escalator, when the human body enters the detection range of the infrared sensor 14, the infrared signal is blocked. The sensor will send an electrical signal to the control system of the microprocessor 110, and the microprocessor 110 will automatically start the device.

[0030] The main camera 15 and two side cameras 17 collect real-time data on passengers' behavior on the escalator and transmit the collected video data to the image processor 112. The image processor 112 decodes and preprocesses the video data in real time. The microprocessor 110 identifies passengers' postures and movements to determine whether they are about to fall backward, play or fight on the escalator, or go against the flow. When the microprocessor 110 determines that an abnormal situation has occurred, it immediately sends a warning signal to the escalator's emergency stop system and the alarm 25. The escalator's emergency stop system stops the escalator immediately, and the alarm 25 emits a high-decibel alarm sound after receiving the warning signal to attract the attention of people around and to notify relevant staff to handle the situation in a timely manner, thereby improving the timeliness and accuracy of the warning and effectively preventing the occurrence of safety accidents.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
