Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator with anti-tailgating scanning function. Background Technology

[0002] An elevator is a vertical transportation device used to efficiently and safely transport people or goods between different floors of a building. Its core function is to achieve rapid movement between floors through a mechanical system, reducing the burden of manual handling and improving building efficiency.

[0003] Traditional elevator internal monitoring components are usually fixed and cannot cover the corners or specific areas of the elevator car, resulting in blind spots. If there are blind spots in the corners or side walls of the elevator car, it may allow tailgating personnel to enter the elevator. Utility Model Content

[0004] The purpose of this invention is to provide an elevator with an anti-tailgating scanning function. This device prevents unauthorized personnel from tailgating into the elevator, thus solving the problem of unauthorized personnel easily tailgating into the elevator in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An elevator with anti-tailgating scanning function includes an elevator car, with grooves on both inner walls of the elevator car, a side door slidably connected inside the grooves, a display screen fixedly connected to the inner wall of the elevator car, and a screw rotatably connected inside the elevator car; a movable plate, which is slidably disposed inside the elevator car, the screw being threadedly connected to the movable plate, and a camera, an infrared sensor, and a laser scanner head fixedly connected to the lower end of the movable plate.

[0007] Preferably, a motor is fixedly connected inside the side wall of the elevator car, and the output end of the motor is fixedly connected to the end of the screw through a coupling.

[0008] Preferably, a protective plate is fixedly connected to the inner wall of the elevator car, the protective plate is located below the movable plate, and the protective plate is made of transparent acrylic material.

[0009] Preferably, a controller and a terminal are fixedly connected inside the side wall of the elevator car, and the controller is electrically connected to the terminal, a camera, an infrared sensor and a laser scanner head.

[0010] Preferably, a crossbar is fixedly connected between the inner walls on both sides of the elevator car, and the crossbar is slidably connected to the movable plate.

[0011] Preferably, two electric actuators are fixedly connected inside the side wall of the side door, the output end of the electric actuator is fixedly connected to the inner wall of the groove, and the electric actuator is electrically connected to the controller.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. After people enter the elevator car, multiple sensors work together to accurately identify whether there are any people following behind. This function can effectively prevent unauthorized personnel from entering specific floors or areas. When tailing behavior is detected, the controller reacts quickly, controlling the electric push rod to prevent the side door from closing, and displays the image of the tailing person on the display screen and sounds a buzzer to drive them away. This timely warning and handling method can make the tailing person realize that their behavior has been discovered, thereby forcing them to leave the elevator car as soon as possible and reducing potential safety threats.

[0014] 2. The motor output drives the screw to rotate through the coupling. The movable plate slides laterally through the threaded engagement between the movable plate and the screw. At the same time, the movable plate drives the camera, infrared sensor and laser scanner head to move laterally, which can comprehensively monitor the inside of the elevator car. Through the lateral movement design, the sensor can cover the entire width of the elevator car, ensuring that every corner is effectively monitored and avoiding blind spots.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 An elevator with anti-tailgating scanning function includes an elevator car 001. Grooves 101 are provided on both inner walls of the elevator car 001. Side doors 002 are slidably connected inside the grooves 101. A display screen 107 is fixedly connected to the inner wall of the elevator car 001. A screw 103 is rotatably connected inside the elevator car 001. A movable plate 003 is slidably disposed inside the elevator car 001. The screw 103 is threadedly connected to the movable plate 003. A camera 301, an infrared sensor 302, and a laser scanner head 303 are fixedly connected to the lower end of the movable plate 003. A laser scanner is fixedly connected inside the elevator car 001 and electrically connected to the laser scanner head 303. The camera 301 captures images of people inside the elevator car 001, and the infrared sensor 302 monitors human infrared signals. The system assists in determining the number and location changes of personnel. Simultaneously, the laser scanner head 303 scans the interior of the elevator car 001 to construct a three-dimensional spatial model, accurately locate passenger positions, and identify tailgating behavior. The screw 103 rotates, and through the threaded engagement between the movable plate 003 and the screw 103, the movable plate 003 slides laterally. At the same time, the movable plate 003 drives the camera 301, infrared sensor 302, and laser scanner head 303 to move laterally, enabling comprehensive monitoring of the interior of the elevator car 001. When tailgating personnel are detected, the side door 002 cannot close, and the display screen 107 displays the image of the tailgating personnel. The buzzer inside the display screen 107 also sounds to drive away the tailgating personnel and remind them to leave the elevator car 001. A personnel entry sensor is fixedly connected to the top of the elevator car 001.

[0023] A motor 102 is fixedly connected inside the side wall of the elevator car 001. The output end of the motor 102 is fixedly connected to the end of the screw 103 through a coupling. The output end of the motor 102 drives the screw 103 to rotate through the coupling.

[0024] A protective plate 104 is fixedly connected to the inner wall of the elevator car 001. The protective plate 104 is located below the movable plate 003. The protective plate 104 is made of transparent acrylic material and divides the interior of the elevator car 001.

[0025] Inside the side wall of elevator car 001, a controller 105 and a terminal 106 are fixedly connected. The controller 105 is electrically connected to the terminal 106, camera 301, infrared sensor 302, and laser scanner head 303. The personnel entry sensor and display screen 107 are also electrically connected to the controller 105. The controller 105 receives data transmitted from the camera 301, infrared sensor 302, and laser scanner head 303, processes and analyzes the data, determines whether there is tailgating behavior, and controls the display content of the display screen 107 and the sound emitted by its internal buzzer based on the judgment result. The terminal 106 receives event information transmitted by the controller 105 and uploads the event information to a remote server so that security personnel or relevant management departments can further process it.

[0026] A crossbar 108 is fixedly connected between the inner walls on both sides of the elevator car 001. The crossbar 108 is slidably connected to the movable plate 003. When the movable plate 003 slides laterally, it is supported and guided by the crossbar 108.

[0027] Two electric actuators 201 are fixedly connected inside the side wall of the side door 002. The output end of the electric actuator 201 is fixedly connected to the inner wall of the groove 101. The electric actuator 201 is electrically connected to the controller 105. The controller 105 controls the operation of the electric actuator 201 according to the judgment result.

[0028] In this invention, when the side door 002 of the elevator car 001 opens and a person enters the elevator car 001, the person entry sensor located at the upper part of the elevator car 001 entrance detects the person's entry and transmits the signal to the controller 105. After receiving the signal, the controller 105 controls the camera 301, infrared sensor 302, and laser scanner head 303 to start working. The camera 301 captures images of the people inside the elevator car 001, and the infrared sensor 302 monitors the human infrared signal to help determine the number and position changes of the people. At the same time, the laser scanner head 303 scans the interior of the elevator car 001 to construct a three-dimensional spatial model, accurately locate the passenger's position, and identify tailgating behavior. The controller 105 receives the data transmitted by the camera 301, infrared sensor 302, and laser scanner head 303, and processes and analyzes the data.

[0029] The controller 105 performs image recognition based on the personnel images captured by the camera 301, and combines the intensity and distribution of human infrared signals monitored by the infrared sensor 302 with the position and movement trajectory of the personnel in the three-dimensional spatial model constructed by the laser scanner head 303. If it finds that the number of personnel does not match the authorized number of people to enter, or that the movement trajectory of the personnel is abnormal, such as after an authorized person enters, an unauthorized person follows into the elevator car 001 and stays in the car for more than a preset threshold, it is determined to be a tailgating behavior.

[0030] When a follower is detected inside elevator car 001, controller 105 controls the operation of electric push rod 201 based on the judgment result, opening side door 002 so that side door 002 cannot be closed. Controller 105 also displays the received data and image of the follower on display screen 107 and controls the buzzer inside display screen 107 to sound, driving away the follower and reminding them to leave elevator car 001.

[0031] The output end of the motor 102 drives the screw 103 to rotate through the coupling. Through the threaded engagement between the movable plate 003 and the screw 103, the movable plate 003 slides laterally. At the same time, the movable plate 003 drives the camera 301, the infrared sensor 302 and the laser scanner head 303 to move laterally, which can perform comprehensive monitoring of the interior of the elevator car 001.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
