Description

Technical Field

[0001] This utility model relates to the field of turnstile technology, and in particular to a turnstile that uses a robotic arm to prevent tailgating. Background Technology

[0002] With the rapid development of urban public transportation, safety issues in densely populated areas such as subway stations and bus stops are becoming increasingly serious. Tailing not only threatens passenger safety but also poses challenges to management. Traditional manual monitoring methods are slow and inefficient, making it difficult to effectively curb tailgating. Installing double-door turnstiles to prevent tailgating through the first door requires more space, and some sites cannot accommodate such devices, as shown in patent document CN110344348A – a turnstile, turnstile control method, and device. Therefore, a new type of turnstile device is urgently needed to improve public safety. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a gate that utilizes a robotic arm to prevent tailgating.

[0004] This utility model is implemented using the following method: a turnstile that uses a robotic arm to prevent tailgating, comprising a turnstile body, a robotic arm, and a sensor for detecting the number of people, as well as a pedestrian passage opened in the turnstile body and a controller installed in the turnstile body. The robotic arm is installed on one side of the pedestrian passage on the turnstile body, and the robotic arm is located on the entrance side of the pedestrian passage. The robotic arm is communicatively connected to the controller. The sensor is installed in the pedestrian passage, and the sensor is communicatively connected to the controller.

[0005] Preferably, the sensor includes an infrared sensor, which is disposed on the gate body on both sides of the pedestrian passage.

[0006] Preferably, multiple infrared sensors are provided and are arranged at intervals along the passage direction of the pedestrian walkway.

[0007] Preferably, multiple sets of external sensor groups are provided on the side walls of the gate body on both sides of the pedestrian passage along the longitudinal direction, and each infrared sensor group is composed of multiple infrared sensors.

[0008] Preferably, multiple infrared sensors are provided on the side walls of the gate body on both sides of the pedestrian passage entrance along the longitudinal direction.

[0009] Preferably, the sensor further includes a camera, which is mounted on the top of the gate body and is used to identify the number of pedestrians in the pedestrian passage.

[0010] Preferably, the robotic arm is installed on the upper end of one side of the gate body at the entrance of the pedestrian passage.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a turnstile that uses a robotic arm to prevent tailgating. Compared with the prior art, this utility model has at least the following technical effects: 1. By setting sensors on the turnstile body to detect the number of people in the passage, and installing a robotic arm on the turnstile, both are connected to a controller. The sensors detect the number of people in the pedestrian passage, and if more than two people are detected, the controller can control the robotic arm to extend and block tailgating; there is no need to set up double gates to prevent tailgating, thus avoiding the turnstile occupying too much space. 2. Multiple infrared sensors are set at intervals in the pedestrian passage to detect whether there are multiple people in the pedestrian passage. 3. Multiple sets of infrared sensor groups are set longitudinally at intervals on the side wall of the turnstile body, which can be used to detect people of different heights. 4. The sensors also include a camera, which can be used to distinguish between objects and people, avoiding the turnstile misidentifying and causing the robotic arm to extend incorrectly to block.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Please see Figures 1 to 2 A turnstile that uses a robotic arm 2 to prevent tailgating includes a turnstile body 1, a robotic arm 2, and a sensor for detecting the number of people, as well as a pedestrian passage 11 opened in the turnstile body 1 and a controller installed in the turnstile body 1. The robotic arm 2 is installed on one side of the pedestrian passage 11 on the turnstile body 1, and the robotic arm 2 is located on the entrance side of the pedestrian passage 11. The robotic arm 2 is communicatively connected to the controller. The sensor is installed in the pedestrian passage 11, and the sensor is communicatively connected to the controller.

[0017] Please see Figures 1 to 2 Preferably, the sensor includes an infrared sensor 3, which is mounted on the gate body 1 on both sides of the pedestrian passage 11. The infrared sensor 3 detects infrared rays emitted by a human body, thus detecting whether a pedestrian has entered the pedestrian passage 11.

[0018] Please see Figures 1 to 2 Preferably, multiple infrared sensors 3 are provided and spaced apart along the passage direction of the pedestrian walkway 11. Multiple infrared sensors 3 are spaced apart in the pedestrian walkway 11 to detect and determine whether there are multiple people in the pedestrian walkway 11. When multiple infrared sensors 3 in the passage direction of the pedestrian walkway 11 receive infrared rays emitted by a human body, it indicates that there may be multiple pedestrians in the walkway at that time.

[0019] Please see Figures 1 to 2 Preferably, multiple sets of external sensors are arranged longitudinally on the side walls of the gate body 1 on both sides of the pedestrian passage 11, and each set of infrared sensors 3 consists of multiple infrared sensors 3. The longitudinally spaced multiple sets of infrared sensors 3 on the side walls of the gate body 1 can be used to detect people of different heights.

[0020] Please see Figures 1 to 2 Preferably, multiple infrared sensors 3 are arranged longitudinally on the side walls of the gate body 1 on both sides of the entrance of the pedestrian passage 11. Multiple sets of infrared sensors 3 are longitudinally spaced on the side walls of the entrance of the pedestrian passage 11 of the gate body 1, which can be used to detect people and objects of different heights. The pedestrian flow in the pedestrian passage 11 can be detected according to the time interval between the triggering of each infrared sensor 3.

[0021] Please see Figures 1 to 2 Preferably, the sensor further includes a camera 4, which is mounted on the top of the gate body 1 and used to identify the number of pedestrians in the pedestrian passage 11. The camera 4 can distinguish between objects and people, preventing gate recognition errors that could cause the robotic arm 2 to extend incorrectly to block. It should be noted that this utility model claims protection for the specific structure; specific methods for identifying the number of passengers and determining their location can employ recognition schemes such as DeepCamera, and the specific control algorithm for the robotic arm 2 is existing technology, such as a PID control strategy algorithm, etc., and is not limited thereto, nor are specific protection requirements made. The infrared sensor 3 and camera 4 work together to improve the accuracy of identification and judgment (e.g., of suitcases and people).

[0022] Please see Figures 1 to 2 Preferably, the robotic arm 2 is installed on the upper end of one side of the gate body 1 at the entrance of the pedestrian passage 11. This allows it to extend and block trailing pedestrians from entering.

[0023] Preferably, the outer layer of the robotic arm 2 is covered with a rubber sleeve to protect pedestrians.

[0024] The working principle of this utility model is as follows:

[0025] In practical applications, this device can be installed in public places such as subway stations and bus stations. Sensors (infrared sensor 3, camera 4) continuously monitor the pedestrian walkway 11. When a passenger is detected passing through, it immediately determines whether it is a single person. If the system detects tailgating (camera 4 detects two or more passengers too close together, and multiple (three or more) infrared sensors 3 in adjacent directions along the pedestrian walkway 11 are simultaneously triggered), the controller will control the robotic arm 2 to quickly extend in front of the tailgating person, blocking their progress. Upon receiving the detection data from the infrared sensors 3 (two or fewer adjacent sensors along the pedestrian walkway 11 being simultaneously triggered) and the camera 4's identification of a single person, the controller will keep the robotic arm 2 in place. This reduces manual intervention and management costs. Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0026] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0027] Finally, the above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.

[0028] It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this utility model should also be considered within the scope of protection of this utility model.
