Description
Technical Field
[0001] This utility model relates to the field of security inspection equipment technology, specifically to security gates used in passenger stations, and more specifically to enclosed AB one-way gates for passenger stations. Background Technology
[0002] With the continuous development of my country's railway transportation infrastructure and the constant increase in passenger traffic, the challenges in passenger safety management are growing. Security checks at the waiting room are a crucial measure and a core element in ensuring public transportation safety.
[0003] Traditional railway passenger stations use serrated one-way gates or serrated one-way mechanical turnstiles at the entrances and exits of waiting rooms for security checks. Serrated one-way gates (also known as serpentine gates or loop gates) are core facilities for one-way crowd control and order management, using physical structure design to achieve forced flow guidance that is "only forward, no backward." Serrated one-way mechanical turnstiles (also known as serpentine turnstiles or maze turnstiles) are intelligent access devices that deeply integrate physical flow guidance structures with mechanical interception systems, specifically designed for rigid one-way control in high-density crowd scenarios. However, both serrated one-way gates and serrated one-way mechanical turnstiles share a common drawback: neither can create a closed space, allowing passengers to freely pass prohibited or dangerous items that are difficult to detect. Therefore, in the existing waiting rooms, especially at the entrance and exit, even after passengers have passed through the security gate, special security personnel still need to check each passenger individually. The security personnel check one person at a time, which results in low inspection efficiency. Especially during holidays when passenger flow is large, queues and congestion are likely to occur at the entrance of the waiting room. Utility Model Content
[0004] In response to the technical problem described in the background art above, the existing security inspection equipment used at the entrances and exits of waiting rooms in railway passenger stations cannot form a closed space, and there is a technical problem that it cannot identify prohibited and dangerous items passed by passengers. In order to address this technical problem, this utility model proposes a closed AB one-way door for passenger stations.
[0005] This utility model uses an automatic door A structure, an automatic door B structure, a side panel, and a top panel to form a closed box-like structure. A control module controls the automatic door A and automatic door B to open and close in a one-way pattern from door A to door B, preventing passengers from entering through door A or exiting through door B and then exiting through door A. This creates a closed, one-way security checkpoint, preventing passengers from passing prohibited or dangerous items and improving the security check effectiveness.

[0013] Further defined, the A automatic door structure includes two fixed A door bodies and two movable A door bodies, the two fixed A door bodies are located on the same plane, and the two fixed A door bodies are respectively connected to two opposing columns;
[0014] The two movable A-gate bodies are located on the same plane and between the two fixed A-gate bodies, and one or both of the movable A-gate bodies are connected to the door operator system.
[0015] Further specifying, the gantry crane system includes a hanging wheel, a gantry crane beam, a drive transmission component, and a limiting component. The gantry crane beam is connected to the column. The drive transmission component and the limiting component are both connected to the gantry crane beam. The drive transmission component is connected to the movable door body of Gate A through the hanging wheel. The limiting component is used to limit the travel of the movable door body of Gate A.
[0016] Further specifying, the limiting component includes a closing limiting block and an opening limiting block, with the closing limiting block positioned near the middle of the gantry beam and the opening limiting block positioned near the end of the gantry beam.
[0017] Further specifying, the top of the column is provided with a door operator top box A and a door operator top box B.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. This utility model relates to a closed AB one-way door for passenger stations. It comprises an A automatic door structure, a B automatic door structure, side panels, and a top panel, forming a closed, enclosed box-like structure. A control module controls the A and B automatic door structures to open and close in a one-way manner from the A automatic door structure to the B automatic door structure. This prevents passengers from entering through the A automatic door structure or exiting through the B automatic door structure, creating a closed, one-way security checkpoint.

When the infrared sensor detects movement within its detection area, it sends the detected signal to the control module. The control module then sends an opening signal to the door operator system of the A automatic door structure, thereby controlling the A automatic door structure to open and allowing passengers to enter the compartment structure. The image sensor identifies human images inside the compartment structure, and the light curtain sensor identifies objects inside the compartment structure, sending the identification information of human images and objects to the control module. Security personnel use the human images and objects on the control module to make judgments. If no abnormalities are found in the human images and objects, they send an instruction to the control module, which then sends an opening signal to the door operator system of the B automatic door structure. The B automatic door structure opens, and passengers leave. Therefore, the passenger station enclosed AB one-way door of this utility model can realize the simultaneous detection of people and objects without the need to separate people and objects, thus improving security inspection efficiency. In addition, when the size of the compartment structure is large enough, multiple people and objects can enter at one time for security inspection, further improving security inspection efficiency and significantly alleviating the queuing and congestion that occur during holidays when passenger flow is large.
[0023] 3. This utility model of a passenger station enclosed AB one-way door also includes an audible and visual alarm and a high-definition camera. The high-definition camera is used to collect personnel information inside the compartment and transmit this information to the command center (station monitoring room). When the monitoring personnel in the monitoring room discover someone illegally entering (entering through the B automatic door structure), they will trigger an audible and visual alarm. Additionally, after the B automatic door structure has started its preset time (3-5 seconds), the image sensor will identify that there are still passengers inside the compartment and will alert them to exit as soon as possible via the audible and visual alarm, allowing the next batch of security checks to proceed.

Detailed Implementation
[0029] The technical solution of this utility model will be further explained and described below with reference to the accompanying drawings and embodiments, but this utility model is not limited to the embodiments described below.
[0030] See Figure 1 and Figure 2 This utility model proposes a closed AB one-way door for passenger stations, including an A automatic door structure 1, a B automatic door structure, two side panels 4, a top plate 7, an infrared sensor 8, a door operator system 9, and a control module 11. The two side panels 4 are arranged opposite each other, and the A automatic door structure 1 and the B automatic door structure are arranged opposite each other, forming a security check channel. The A automatic door structure 1, the B automatic door structure, the two side panels 4, and the top plate 7 together form a closed box-like structure, from... Figure 1 and Figure 2 As can be seen, automatic door structure A 1, one side panel 4, automatic door structure B, and another side panel 4 are connected end to end. A door operator system 9 is installed above both automatic door structure A 1 and automatic door structure B. The door operator system 9 is connected to the control module 11, and the control module 11 controls automatic door structure A 1 and automatic door structure B to form a one-way opening and closing mode along automatic door structure A 1 to automatic door structure B through the door operator system 9.
[0031] In this utility model, the structure of automatic door structure A 1 is the same as that of automatic door structure B.
[0032] In this utility model, the control module 11 is an existing product purchased directly from the market. It is a Cortex-M4 STM32F407 product manufactured by ARM. However, the control module 11 of this utility model is not limited to this model. Any control module 11 that can realize the functions of this utility model is acceptable.
[0033] This utility model uses an automatic door structure 1 (A), an automatic door structure (B), a side panel 4, and a top panel to form a closed box-like structure. A control module 11 controls the automatic door structures 1 and 1 to open and close in a one-way manner from A to B, preventing passengers from entering through A or B and exiting through A. This creates a closed, one-way security checkpoint, preventing passengers from passing prohibited or dangerous items and improving the security check effectiveness. Simultaneously, it achieves automated security checks, increasing efficiency.

[0035] The working process of the image sensor, light curtain sensor, and infrared sensor 8 is as follows: When the infrared sensor 8 detects movement within the detection area, it sends the detected signal to the control module 11. The control module 11 sends an opening signal to the door operator system 9 of automatic door structure A, thereby controlling automatic door structure A to open and allowing passengers to enter the compartment. The image sensor identifies the human image inside the compartment, and the light curtain sensor identifies the object inside the compartment, and sends the identification information of the human image and object to the control module 11. Security personnel make judgments based on the human image and object on the control module 11 (specifically, a display module can be connected to the control module 11, and security personnel can observe the information of the human image and object through the display module). If it is determined that there is no abnormality in the human image and object, it sends an instruction to the control module 11, and the control module 11 sends an opening signal to the door operator system 9 of automatic door structure B, causing automatic door structure B to open and allowing passengers to leave. Therefore, the passenger station enclosed AB one-way door of this utility model can realize the simultaneous detection of people and objects without the need to separate people and objects, thus improving security inspection efficiency. In addition, when the size of the compartment structure is large enough, multiple people and objects can enter at one time for security inspection, further improving security inspection efficiency and significantly alleviating the queuing and congestion that occur during holidays when passenger flow is large.
