Abstract
Description
Technical Field
[0001] This utility model relates to the field of turnstile technology, and in particular to a turnstile with free passage function. Background Technology
[0002] Traditional rail transit station turnstiles primarily operate in a "normally closed" mode, requiring passengers to swipe their cards and wait for the gates to open before passing through. With the increasing proportion of rail travel, the traditional turnstile mode cannot meet the daily passenger flow demands. Therefore, major cities' rail transit systems are piloting "normally open" modes to reduce gate opening and closing time and improve throughput. However, in the "normally open" mode, if a passenger fails to swipe their card or accidentally enters, the gate will immediately close to prevent injury. Utility Model Content
[0003] The purpose of this utility model is to provide a turnstile with free passage function, which solves the problem that neither the normally closed nor normally open modes of the existing turnstiles can meet the needs of passenger flow.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a turnstile with free passage function, comprising a turnstile body, a central monitoring system, and a passage logic controller, further comprising: a hardware control module, which includes a rocker switch, photoelectric sensors, and a photoelectric converter. The photoelectric sensors are evenly distributed on both sides of the entrance and exit of the turnstile channel to collect data on light signal occlusion during passenger passage in real time. The photoelectric converter converts the light signal into an electrical signal and transmits it to the passage logic controller; a safety detection module, comprising multiple sets of behavior monitoring sensors installed in the turnstile body channel to monitor the passenger's passage direction, speed, and abnormal behavior; an audible and visual warning unit connected to the behavior monitoring sensors, comprising a voice announcer, a top-mounted LED warning light, and a passenger display screen, for simultaneously issuing voice prompts, light warnings, and text alarms when an abnormality is detected; and a mode switching module, comprising a mode selection switch integrated into the central control system, the mode selection switch being electrically connected to the passage logic controller; the mode switching module can also communicate with the central monitoring system to receive remote commands to achieve automatic mode switching.
[0005] Preferably, in the hardware control module, the boat-shaped switch is a double-pole double-throw switch, with its first throw connected to the door closing signal line in the traditional "normally closed" mode and its second throw connected to the normally open control circuit in the "free passage" mode. Hardware logic isolation between modes is achieved by switching the throw positions.
[0006] Preferably, the photoelectric sensor includes at least four sets of infrared beam sensors, which are respectively arranged at the top of the entrance, the bottom of the entrance, the top of the exit, and the bottom of the exit of the gate channel, for accurately determining the passenger's passage trajectory and position.
[0007] Preferably, the behavior monitoring sensor further includes a pressure sensing strip installed on the floor of the gate passage. The pressure sensing strip extends along the passage direction and determines the passenger's passage speed and whether there is any rapid running behavior by detecting pressure changes.
[0008] Preferably, in the sound and light warning unit, the voice broadcaster is embedded in the top of the gate and supports multilingual voice prompts; the top LED warning light is a dual-color red and yellow light, with the red light used to warn of illegal behavior and the yellow light used to warn of missed scans; the passenger display screen is a touch screen that can display ticket verification results and real-time alarm information.
[0009] Preferably, the mode switching module further includes a mode status indicator light, which is linked to the mode selection switch and provides intuitive feedback on the current gate operation mode through different colors.
[0010] Preferably, the hardware control module further includes an overload protection circuit, which is connected in series in the gate drive circuit and is used to automatically cut off the power supply when the gate motor is overloaded, thereby protecting the equipment safety.
[0011] Preferably, the security detection module further includes a data storage unit, which is connected to the behavior monitoring sensor to record the time, location, and type of abnormal behavior for later data analysis and system optimization.
[0012] This invention offers at least the following advantages: The mode switching module serves as the entry point, enabling switching between "free passage" mode and traditional mode by adjusting the boat-shaped switch state of the hardware control module. In "free passage" mode, the hardware control module keeps the gate constantly open, while providing data support for ticket verification through photoelectric sensors and photoelectric converters. In "free passage" mode, the security detection module assumes core monitoring responsibilities, detecting anomalies in real time through behavior monitoring sensors and replacing traditional gate obstruction with an audible and visual warning unit. These three modules interact through a passage logic controller, ensuring both ticketing and passenger safety while improving passage efficiency.
[0013] Improving throughput: The "free passage" mode eliminates the time required for gate opening and closing. Passengers can pass directly after swiping their cards, scanning codes, or completing identity verification, effectively reducing the time spent at the gates. Compared to the traditional "normally closed" mode, the "free passage" mode can actually improve passenger throughput by 110%-120%, alleviating passenger flow pressure during peak hours and increasing the venue's passenger capacity. Improving passenger experience: The "free passage" mode fundamentally avoids passenger injuries caused by gates trapping people. The fast and smooth passage process makes passenger travel more convenient and comfortable, reducing the hassle of queuing and increasing passenger satisfaction with rail travel.
[0014] Cost savings: Reduced opening and closing of the gates lowers energy consumption; at the same time, reduced wear on gate components extends equipment lifespan, reduces maintenance frequency and costs, lowers the risk of operational interruptions due to equipment failure, and improves operational stability.

[0026] Reference Figure 1-4 A gate with free passage function includes a gate body 1, a central monitoring system, and a passage logic controller. It also includes a hardware control module. A rocker switch is connected in series on the closing signal line between the passage logic controller and the gate. The input of the rocker switch is connected to the output of a photoelectric converter, and the output is connected to the gate's drive circuit. The opening and closing action of the gate is independently controlled by the on / off state of the rocker switch. The hardware control module also includes photoelectric sensors and a photoelectric converter. The photoelectric sensors are evenly distributed on both sides of the entrance and exit of the gate body 1 channel to collect real-time data on light signal occlusion during passenger passage. The photoelectric converter converts the light signal into an electrical signal and transmits it to the passage logic controller.
[0027] The security detection module includes multiple sets of behavior monitoring sensors installed in the gate channel. The behavior monitoring sensors include at least one of an infrared beam sensor 4, a pressure sensor, or a camera, used to monitor the passenger's passage direction, speed, and abnormal behavior.
[0028] The sound and light warning unit is connected to the behavior monitoring sensor signal. The sound and light warning unit includes a voice broadcaster 3, an LED warning light on the top of the aircraft 2 and a passenger display screen 5, which are used to simultaneously issue voice prompts, light warnings and text alarms when an abnormality is detected.
[0029] Mode switching module; a mode selection switch integrated into the gate control system. The mode selection switch is connected to the access logic controller via hardwire or bus and supports manual switching of three modes: "normally closed", "normally open" and "free passage".
[0030] The mode switching module can also communicate with the central monitoring system and receive remote commands to achieve automatic mode switching.
[0031] Furthermore, in the hardware control module, the rocker switch is a double-pole double-throw switch. Its first throw is connected to the door closing signal line in the traditional "normally closed" mode, and the second throw is connected to the normally open control circuit in the "free passage" mode. Hardware logic isolation between modes is achieved by switching the throw position.
[0032] Furthermore, the photoelectric sensor includes at least four sets of infrared beam sensors 4, which are respectively arranged at the top of the entrance, the bottom of the entrance, the top of the exit, and the bottom of the exit of the gate channel, for accurately determining the passenger's passage trajectory and position.
[0033] Furthermore, the behavior monitoring sensor also includes a pressure sensing strip 7 installed on the floor of the gate passage. The pressure sensing strip 7 extends along the passage direction and determines the passenger's passage speed and whether there is any fast running behavior by detecting pressure changes.
[0034] Furthermore, in the sound and light warning unit, the voice broadcaster 3 is embedded in the top of the gate and supports multilingual voice prompts; the top LED warning light 2 is a dual-color red and yellow light, with the red light used to warn of illegal behavior and the yellow light used to warn of missed scans; the passenger display screen 5 is a touch screen that can display ticket verification results and real-time alarm information.
[0035] Furthermore, the mode switching module also includes a mode status indicator light 6, which is linked to the mode selection switch and provides intuitive feedback on the current gate operation mode through different colors.
[0036] Furthermore, the hardware control module also includes an overload protection circuit, which is connected in series in the gate drive circuit to automatically cut off the power supply when the gate motor is overloaded, thus protecting the equipment.
[0037] Furthermore, the security detection module also includes a data storage unit, which is connected to the behavior monitoring sensor to record the time, location, and type of abnormal behavior for later data analysis and system optimization.
[0038] In its specific implementation, this turnstile system is particularly suitable for passenger flow verification scenarios at the entrance and exit gates of rail transit stations. To meet the verification requirements of different ticketing media, a card reader area 9 and a card insertion slot 8 are added to both sides of the passage of the turnstile body 1: the card reader area 9 adopts a contactless card reader module, supporting proximity sensing of IC cards such as bus cards and electronic tickets; the card insertion slot 8 is located at the bottom of the turnstile panel, compatible with insertion verification of physical tickets such as single-journey tickets and paper tickets. Both the card reader area 9 and the card insertion slot 8 are electrically connected to the access logic controller, and the verification data is transmitted to the central monitoring system in real time.
[0039] Entrance verification process:
[0040] When a passenger swipes their card at card reader 9 or inserts their ticket into card slot 8, the system immediately performs media verification.
[0041] When the verification is successful, the LED warning light 2 on the top of the machine lights up green, and the voice broadcaster 3 simultaneously broadcasts "Verification successful, please pass quickly". The boat-shaped switch switches to the "free passage" mode, and the gate remains open.
[0042] If the verification fails, the LED warning light 2 on the top of the device will turn red, and the announcer will display "Verification error, please re-verify." If the infrared beam sensor 4 detects unauthorized personnel forcibly passing through at this time, the camera at the top of the passage will automatically capture a facial image, and the abnormal information will be simultaneously uploaded to the central monitoring system for recording and tracking.
[0043] Exit verification process:
[0044] The following design optimizations were made for the exit scenario:
[0045] When verification is successful, a green light illuminates and a passage prompt is played, while the gate remains open. If a passenger fails to scan the code or verification fails, the system allows the passenger to rectify the issue after exiting the station in two ways: either by scanning the code and having points deducted at the manual service counter located at the exit, or by completing a supplementary verification before re-entering the station. This design avoids congestion caused by verification failures at traditional turnstiles, significantly improving passage efficiency.
[0046] In a specific implementation, the pressure sensing strip 7 extends along the central axis of the gate passage. When abnormal passenger speed (such as running) is detected, the voice broadcaster 3 immediately issues a prompt: "Slow down and be careful." In particular, when verification fails, the gate drive circuit remains open via a rocker switch, preventing the risk of pinching and allowing passengers to leave the passage for assistance. Passage can be re-verified after the problem is resolved.
[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
