Description
Technical Field
[0001] This utility model relates to ticket gate technology, and more particularly to an automatic ticket gate control system. Background Technology
[0002] In rail transit engineering, the Automatic Gate Machine (AGM) control system is divided into a main side and a secondary side. The main side includes: a power supply module, an electronic control unit, a single-journey ticket collection module, a power amplifier module, a display screen, a door module, a passage logic control module, a switch, a main-side facial recognition module, and a main-side reader / writer module.

[0023] By combining the motor drive module and the motor into one, and integrating the motor drive part into the motor, the power line and feedback line in the electrical design can be eliminated.

[0024] In the automatic ticket gate system, each module is networked in a master-slave mode using the industrial Ethernet EtherCAT bus, providing a maximum effective data rate of nearly 100Mbps line speed, and enabling the real-time performance of network latency to reach the microsecond level.
[0025] In summary, the entire automatic ticket gate simplifies the internal module structure of the main and auxiliary sides, reducing the overall length to about 60% of that of traditional automatic ticket gate systems; the power supply and communication lines between modules are also reduced, lowering maintenance difficulty and cost.

[0037] Figure 1 A schematic diagram of an automatic ticket gate control system provided for the prior art, such as... Figure 1 As shown, by adding another switch on the secondary side, an IP network architecture is constructed, with the main and secondary switches as the centers and each module connected via Ethernet. Ethernet communication is used between the main and secondary sides, eliminating the need for I / O communication lines between the main and secondary door modules. A power adapter board is added to the secondary side to allow the four power supply signals from the main side to pass through the machine before being distributed to the secondary side modules. A passage logic control module is added to the secondary side to control various indicator lights and the received position / maintenance switch. Although this scheme reduces the number of machine-passing lines, the number of modules on the main and secondary sides is not reduced. Ticket readers and facial recognition terminals still need to be installed on both the main and secondary sides, and the internal electrical connections between the main and secondary sides remain complex.
[0038] To address the above problems, this utility model provides an automatic ticket gate control system. Figure 2 This utility model provides a structural schematic diagram of an automatic ticket gate control system, as shown below. Figure 2 As shown, the automatic ticket gate control system includes a main side 100 and a secondary side 200.
[0039] The main side 100 includes an electronic control unit 110, a power module 120, a main side access logic control module 130, and a main side door module 140. The power module 120 is connected to the electronic control unit 110, the main side access logic control module 130, and the main side door module 140 (only the connection between the power module 120 and the electronic control unit 110 is shown in the figure), and is used to supply power to these components. The electronic control unit 110 is connected to both the main side access logic control module 130 and the main side door module 140. The electronic control unit 110 integrates a face recognition module 111 and a ticket reading / writing module 112. The face recognition module 111 connects to the main side face recognition camera module 101 and the secondary side face recognition camera module 201, and the ticket reading / writing module 112 connects to the main side ticket reading / writing antenna 102 and the secondary side ticket reading / writing antenna 202. The main side access logic control module 130 is connected to the main side direction indicator, card swipe indicator, access indicator, guide indicator and other indicator lights through I / O control signals, and is connected to the main side maintenance door switch, top cover switch, ticket box switch and other position switches. It outputs control signals to control the main side indicator lights, receives input signals from the main side position switches and feeds them back to the electronic control unit 110.
[0040] The secondary side 200 includes a secondary side access logic control module 210, a power adapter board 220, and a secondary side door module 230. The power module 120 is connected to the power adapter board 220 via a cable, and is used to convert the voltage output by the power module 120 into the voltage required by each module of the secondary side 200. The power adapter board 220 is connected to both the secondary side access logic control module 210 and the secondary side door module 230, and is used to supply power to both modules. The electronic control unit 110 is connected to both the secondary side access logic control module 210 and the secondary side door module 230. The secondary access logic control module 210 is connected to the secondary side direction indicator, card swipe indicator, access indicator, guide indicator and other indicator lights through I / O control signals, and is connected to the secondary side maintenance door switch, top cover switch, ticket box switch and other position switches. It outputs control signals to control each indicator light on the secondary side, receives input signals from each position switch on the secondary side, and feeds them back to the electronic control unit 110 through the main access logic control module 130.
[0041] For example, the main-side face recognition camera module 101 is used to capture the user's face image and upload it to the face recognition module 111. The face recognition module 111 processes the face image, identifies the user, and determines the user's corresponding transportation account. If the transportation account has sufficient balance, the electronic control unit 110 sends a command to the main-side door module 140 to control the main-side door to open. The secondary-side face recognition camera module 201 is used to capture the user's face image and upload it to the face recognition module 111. The face recognition module 111 processes the face image, identifies the user, and determines the user's corresponding transportation account. If the transportation account has sufficient balance, the electronic control unit 110 sends a command to the secondary-side door module 230 to control the secondary-side door to open.
[0042] For example, the main-side ticket reader / writer antenna 102 is used to collect card swiping data and upload it to the ticket reader / writer module 112. The ticket reader / writer module 112 processes the card swiping data to determine the account balance of the transportation card. If the balance is sufficient, the electronic control unit 110 sends a command to the main-side door module 140 to control the main-side door to open. The secondary-side ticket reader / writer antenna 202 is used to collect card swiping data and upload it to the ticket reader / writer module 112. The ticket reader / writer module 112 processes the card swiping data to determine the account balance of the transportation card. If the balance is sufficient, the electronic control unit 110 sends a command to the secondary-side door module 230 to control the secondary-side door to open.
[0043] The automatic ticket gate control system provided by this utility model includes a main side and a secondary side. The main side includes an electronic control unit, a power supply module, a main side passage logic control module, and a main side door module. The power supply module is connected to the electronic control unit, the main side passage logic control module, and the main side door module. The electronic control unit integrates a face recognition module and a ticket reading and writing module. The face recognition module is used to connect to the main side face recognition camera module and the secondary side face recognition camera module. The ticket reading and writing module is used to connect to the main side ticket reading and writing antenna and the secondary side ticket reading and writing antenna. The electronic control unit is connected to the main side passage logic control module and the main side door module. The secondary side includes a secondary side passage logic control module, a power adapter board, and a secondary side door module. The power supply module is connected to the power adapter board, and the power adapter board is connected to the secondary side passage logic control module and the secondary side door module. The electronic control unit is connected to the secondary side passage logic control module and the secondary side door module. This invention integrates the main and auxiliary face recognition terminals and the main and auxiliary ticket readers into the electronic control unit, which simplifies the internal structure of the main and auxiliary sides, shortens the length of the automatic ticket gate control system, and simplifies the power supply and communication lines between modules, thereby reducing maintenance difficulty and cost.
[0044] Figure 3 A schematic diagram of another automatic ticket gate control system provided by this utility model is shown below. Figure 3As shown, the automatic ticket gate control system includes a main side and a secondary side.
[0045] The main side includes an electronic control unit (ECU in the diagram), a power module, a main side access logic control module, a main side door module, and a main side switch.
[0046] The power module converts external power, outputting 5V, 12V, 24V, and 48V power to supply the main modules. It also connects to a power adapter board via a power supply cable, which outputs 5V, 12V, 24V, and 48V power to supply the secondary modules. The electronic control unit connects to the power module via an RS232 interface, controlling each output group of the power module and collecting information such as temperature, current, and voltage from the power module for feedback control.
[0047] The electronic control unit integrates a face recognition module and a ticket reading / writing module. The face recognition module connects to the main and secondary face recognition camera modules via a USB interface, while the ticket reading / writing module connects to the main ticket reading / writing antenna (antenna 1 in the diagram) and the secondary ticket reading / writing antenna (antenna 2 in the diagram). Traditional electronic control units, such as those from Advantech and Acer, are based on the Intel platform architecture. Currently, face recognition terminals and readers use the RK3399 platform architecture, and the RK platform can run Linux. Therefore, the electronic control unit of this invention adopts the RK platform, selecting a CPU more powerful than the RK3399, such as the 3588, with a 4-core Cortex-A76 + 4-core Cortex-A55 big.LITTLE architecture, possessing powerful data processing capabilities. Its built-in 6T computing power NPU integrates Rockchip's fourth-generation artificial intelligence computing engine, supporting mixed operations of INT4 / INT8 / INT16 / FP16, and supporting the conversion of network models based on a series of frameworks such as TensorFlow / MXNet / PyTorch / Caffe, suitable for various complex AI computing tasks. In addition to normal operation, this electronic control unit is equipped with the ability to simultaneously integrate face recognition and ticket reading / writing algorithms, making the electronic control unit, face recognition terminal, and ticket reader / writer module a three-in-one unit.
[0048] The main-side switch is connected to the main-side access logic control module, the electronic control unit, and the main-side gate module. The electronic control unit is connected to the main-side switch via Ethernet. As the master controller, the electronic control unit interacts with the main-side access logic control module and the main-side gate module through the switch.
[0049] The main side access logic control module connects to the main side direction indicator, card swipe indicator, access indicator, guide indicator and other indicator lights through I / O control signals, and connects to the main side maintenance door switch, top cover switch, ticket box switch and other position switches. It outputs control signals to control the main side indicator lights, receives input signals from the main side position switches and feeds them back to the electronic control unit.
[0050] The secondary side includes a secondary side access logic control module, a power adapter board, a secondary side door module, and a secondary side switch.
[0051] The power module and the power adapter board are connected via power supply cables to convert the voltage output by the power module into the voltage required by the various modules on the secondary side. The power adapter board is connected to the secondary side access logic control module, the secondary side door module, and the secondary side switch, respectively, to supply power to these modules.
[0052] The secondary switch is connected to the secondary access logic control module, the primary switch, and the secondary door module. The electronic control unit interacts with the secondary access logic control module and the secondary door module through the primary and secondary switches.
[0053] The secondary access logic control module connects to secondary side indicator lights such as direction indicator lights, card swipe indicator lights, access indicator lights, and guide indicator lights via I / O control signals. It also connects to secondary side maintenance door switches, top cover switches, ticket box switches, and other position switches. The module outputs control signals to control the secondary side indicator lights, receives input signals from the secondary side position switches, and feeds them back to the electronic control unit through the primary access logic control module.
[0054] The main side also includes a single-journey ticket collection module, which is connected to the electronic control unit via an RS232 interface.
[0055] The electronic control unit also integrates a power amplifier module (power amplifier shown in the figure), which is used to connect to a speaker, allowing the speaker to broadcast prompts to the user. Traditional electronic control units, due to their versatility, do not integrate power amplifier modules of 15W or higher. However, automatic ticket gate control systems typically require a noise level of 50 dB within 0.5m of the device, necessitating a power amplifier of 15W or higher. The TDA7297 can amplify the audio signal and output it to the speaker. Existing automatic ticket gate control systems, due to the numerous modules and shared power ground, generate ground noise that negatively impacts the user experience. Adding an audio isolator between the power amplifier and the speaker complicates the electrical design. This invention adds an audio transformer to the output of the TDA7297, resulting in a small size and low cost.
[0056] The main side also includes a main-side QR code module, and the secondary side also includes a secondary-side QR code module. The electronic control unit (ECU) is connected to both the main-side and secondary-side QR code modules via an RS232 interface. For example, the main-side QR code module scans the QR code presented by the user and uploads it to the ECU. The ECU processes the QR code, identifies the user's transportation account, and determines the account balance. If the balance is sufficient, the ECU sends a command to the main-side door module via the main-side switch to open the main-side door. Similarly, the secondary-side QR code module scans the QR code presented by the user and uploads it to the ECU. The ECU processes the QR code, identifies the user's transportation account, and determines the account balance. If the balance is sufficient, the ECU sends a command to the secondary-side door module via the main-side and secondary-side switches to open the secondary-side door.
[0057] The main side also includes a main side display screen, and the secondary side also includes a secondary side display screen. The electronic control unit is also connected to the main side display screen and the secondary side display screen via a VGA interface, and outputs guidance information and account balance information to the main side display screen and the secondary side display screen.
[0058] The automatic ticket gate control system also includes a visual access module, which is connected to the electronic control unit. Traditional automatic ticket gate control systems use 16-18 through-beam sensors on the gate body for detection, equivalent to a resolution of 16-18 points (one-dimensional spatial detection). These through-beam sensors need to be deployed on both the main and auxiliary sides, occupying nearly half of the electrical connections in the power and control lines of the automatic ticket gate control system. This invention replaces the original through-beam sensors with a visual access module, requiring only a power and communication line connection to the main side's electronic control unit, greatly simplifying the electrical design and upgrading the detection space to three dimensions.
[0059] Figure 4 This is a structural schematic diagram of a visual access module provided by this utility model, as shown below. Figure 4As shown, the visual access module includes a laser projector, a Time-of-Flight (TOF) sensor, a color image sensor, a vision processor, and a logic processor. The laser projector, TOF sensor, and color image sensor are all connected to the vision processor, which in turn is connected to the logic processor (RK3568 in the diagram). The logic processor is connected to the access logic control module. The laser projector is a modulated collimated laser that also acts as the transmitter; its shutter is controlled by the vision processor. The TOF sensor, acting as the receiver, typically uses a single photodiode to acquire a complete scene depth map or depth data through a single-image imaging technique. The color image sensor acquires a color image (RGB image). The color image sensor component provides intrinsic, extrinsic, and distortion parameters. The vision processor can employ a high-real-time FPGA or a horizon processor used in autonomous driving, outputting the calculated depth data to the logic processor via USB. The advantages of the TOF-based visual access module are a large field of view and strong resistance to light interference, making it suitable for use in stations with limited height or in non-underground stations.
[0060] Figure 5 A schematic diagram of another visual access module provided by this utility model is shown below. Figure 5 As shown, the visual access module includes a laser projector, a structured light sensor, a color image sensor, a vision processor, and a logic processor (RK3568 in the figure). The laser projector, structured light sensor, and color image sensor are all connected to the vision processor, which in turn is connected to the logic processor. The logic processor is connected to the access logic control module. The structured light sensor consists of left and right infrared image sensors. The active binocular depth camera supports receiving commands from the logic processor via a USB or Ethernet interface, enabling software-triggered image acquisition. Cameras with hardware trigger interfaces support external hardware signal triggering, acquiring images according to the frequency of the trigger signal (≤ the frame rate of continuous mode). The laser projector emits structured light onto the surface of the object being measured. The color image sensor acquires RGB data, and the infrared image sensor receives both infrared data streams. Using the embedded vision processor as a computing platform, the depth data of each point within the field of view is calculated at high speed based on the triangulation principle. Because the image data output by the color image sensor needs to be synchronized with the infrared image data, a color image sensor without a hardware ISP module is selected to output a RAW BAYER image. This may result in color casts in the image, requiring additional software ISP processing (such as white balance) via the SDK. The processed image is then displayed as a color image in a normal color space. The advantages of the 3D structured light vision access module are stable depth data and low cost, making it suitable for use in numerous underground stations.
[0061] The visual access module in this invention can accurately calculate the current position information of a target, determine whether the target is a person or an object, distinguish between adults and children, and simultaneously track and judge multiple moving targets. However, depth maps can have certain errors in determining the effective outline information of a person or object, or a combination of a person and an object, under irregular conditions. For example, when a person passes through the gate with their arms outstretched, the effective outline information of the person and the stroller combined is obtained; when a person passes through the gate with a stroller, the effective outline information of the person and the stroller combined is obtained; when a person passes through the gate with an umbrella, the effective outline information of the person and the umbrella combined is obtained, etc. To address this problem, this invention can calculate the current position and height information of the target through depth images, determine whether the target is a person or an object, and simultaneously track and judge multiple targets, including tracking and identifying passengers following behind. Then, it uses RGB images to determine whether the passenger is an adult or a child, whether there is a pregnant woman among the adults, and whether the object is a suitcase, stroller, wheelchair, hat, or umbrella. The combination of a person and an object includes a passenger carrying a suitcase, a passenger pushing a stroller and determining whether there is an infant in the stroller, a passenger pushing a wheelchair and determining whether there is anyone in the wheelchair, a passenger wearing a hat, and a passenger holding an umbrella. Finally, the information of the area where the person and object are located is given to the access logic control board for behavior recognition and judgment.
[0062] In this embodiment of the invention, both the main side door module and the secondary side door module integrate a motor drive unit and a door operator. Existing door modules include a mechanical part and a motor part. The motor drive module controls the rotation of the motor in the door mechanism, and the control lines between the two include power lines (three-phase U, V, W) and feedback lines (encoding lines / Hall signals). This invention combines the motor drive unit and the door operator into one unit. Integrating the motor drive unit inside the motor eliminates the need for power and feedback lines in the electrical design, and eliminates the need for an external drive control system housing, saving wiring space between the motor and the drive. The only external interfaces of the entire door module are the power and communication terminals, saving costs. The integrated motor effectively reduces the failure rate of the entire door module equipment.
[0063] Figure 6 A schematic diagram of another automatic ticket gate control system provided by this utility model is shown below. Figure 6 As shown, the parts that are the same as those in the previous embodiments will not be repeated here. The difference between this embodiment and the previous embodiments is as follows:
[0064] The electronic control unit (ECU) is connected to the main access logic control module (represented by ECAT in the diagram) via an industrial Ethernet bus (EtherCAT). The main access logic control module is connected to the main door module via the EtherCAT bus. The ECU is also connected to the secondary access logic control module via the EtherCAT bus, and the secondary access logic control module is connected to the secondary door module via the EtherCAT bus.
[0065] The modules in the aforementioned embodiments are networked according to Ethernet mode, with a network latency of less than 100ms, which meets the needs of most applications. However, for applications with higher real-time requirements, an industrial Ethernet bus with better real-time performance is needed. The EtherCAT bus retains the standard Ethernet physical layer and builds a completely new deterministic protocol on top of it. This protocol uses a host controller, which is the only device allowed to create EtherCAT frames. The frame length is always the same, and each device node on the network has a dedicated frame-addressable area. When a frame is transmitted in the network, each node selects control data and discards reply information in its allocated space as it passes through. The frame latency does not exceed the hardware transmission latency, while providing a maximum effective data rate close to 100Mbps line speed, enabling the network real-time performance to reach the μS level. EtherCAT bus technology is implemented directly on the Ethernet hardware platform in a master-slave configuration. The cycle time is short because the microprocessor of the slave station does not need to process Ethernet packets. EtherCAT uses a full-duplex Ethernet physical layer, and a slave station may have two or more ports. If a device does not detect other devices downstream, the slave station's controller will automatically close the corresponding port and send back an Ethernet frame. Therefore, EtherCAT supports almost all network topologies, including bus, tree, or star topologies. EtherCAT topologies can be arbitrarily combined using network cables, branches, or short cables.
[0066] The characteristics of the EtherCAT bus dictate that the electronic control unit in this invention acts as the master station, with each master-slave module acting as a slave station, eliminating the need for an intermediate switch. This eliminates the need for the master and slave switches in the automatic ticket gate control system. In industrial automation, continuous operation of the devices on the bus is typically required, and production stoppages are not permitted. Redundancy technology ensures the reliability and stability of the application system. Therefore, this invention designs the communication line between the master and slave devices as a ring structure with two branches, achieving link redundancy. When a cable break occurs, the two links continue to operate. Simultaneously, EtherCAT can automatically detect fault points in the bus system, greatly simplifying system maintenance and improving equipment maintainability.
[0067] The specific system architecture is as follows: Figure 6As shown, the power module outputs 5V, 12V, 24V, and 48V power to power the modules on the main side and connects to the power adapter board on the secondary side via 12V, 24V, and 48V power lines (since the secondary side switch is eliminated, the 5V power does not need to pass through the machine). The power adapter board outputs 12V, 24V, and 48V power to power the modules on the secondary side. The electronic control unit connects to the power module, single-journey ticket collection module, main side QR code module, and secondary side QR code module via RS232 interface, to the main side face recognition camera module and secondary side face recognition camera module via USB interface, to the main side ticket reading and writing antenna and secondary side ticket reading and writing antenna via antenna feeder, to the main side display screen and secondary side display screen via VGA / HDMI, to the external network via Ethernet port, and to the speakers via power amplifier output. The electronic control unit is connected to the main side access logic control module via an EtherCAT bus. The main side access logic control module is connected to the main side door module via an EtherCAT bus. The main side door module is connected to the visual access module via an EtherCAT bus. The visual access module is connected to the secondary side door module via an EtherCAT bus. The secondary side door module is connected to the secondary side access logic control module via an EtherCAT bus. The secondary side access logic control module is connected to the electronic control unit via an EtherCAT bus.
[0068] Figure 7 A schematic diagram of another automatic ticket gate control system provided by this utility model is shown below. Figure 7 As shown, the parts that are the same as those in the previous embodiments will not be repeated here. The difference between this embodiment and the previous embodiments is as follows:
[0069] The secondary access logic control module and the power adapter board are integrated to form a controller area network (CAN) bus relay module. The power module is connected to the CAN bus relay module, and the CAN bus relay module is connected to the primary access logic control module via the CAN bus. The primary door module is connected to the secondary door module via the CAN bus.
[0070] The aforementioned embodiments are all implemented in a high-speed network such as 100M Ethernet. For the current conventional automatic ticket gate control system, the main link can also meet most usage scenarios and is less expensive. Existing old modules on site also support CAN bus, so it is more suitable for the transformation and upgrading of old machines.
[0071] The specific system architecture is as follows: Figure 7As shown, the power module outputs 5V, 12V, 24V, and 48V power to power the modules on the main side and connects to the secondary side CAN bus relay module via 12V, 24V, and 48V power supply lines (since the secondary side switch is eliminated, the 5V power supply does not need to pass through the machine). The secondary side CAN bus relay module outputs 12V, 24V, and 48V power to power the modules on the secondary side. The electronic control unit (ECU) in the diagram connects to the power module, single-trip ticket collection module, main side QR code module, and secondary side QR code module via RS232 interface, to the main side face recognition camera module and secondary side face recognition camera module via USB interface, to the main side ticket reading and writing antenna and secondary side ticket reading and writing antenna via antenna feeder, to the main side display screen and secondary side display screen via VGA / HDMI, to the external network via Ethernet port, to the speaker via power amplifier output, and to the main side access logic control module via CAN bus. The main side access logic control module is connected to the main side door module via an RS232 interface, to the visual access module via an RS485 interface, and to the secondary side CAN bus relay module via a CAN bus. It is also connected to the main side direction indicator, card swipe indicator, access indicator, and guide indicator via I / O control signals, and to the main side maintenance door switch, top cover switch, and ticket box switch. The secondary side CAN bus relay module is connected to the secondary side direction indicator, card swipe indicator, access indicator, and guide indicator, and to the secondary side maintenance door switch, top cover switch, and ticket box switch. The main side door module is connected to the secondary side door module via a separate CAN bus.
[0072] This embodiment simplifies and integrates the power adapter board and the secondary access logic control module into one. The secondary access logic control module has multiple communication interfaces (including RS232, RS485, CAN, and Ethernet) to handle communication with different devices. Since the secondary side only needs to support CAN, the original secondary access logic control module can be simplified into a CAN bus relay module to communicate with the primary access logic control module, parse the control commands of the primary access logic control module, and control the indicator lights.
[0073] As mentioned earlier, the integration of the main and secondary side modules has greatly simplified the secondary side modules. Only the secondary side door module, CAN bus relay module, and secondary side display screen require power. With the reduction in the number of interfaces, the functions can be directly integrated into the CAN bus relay module.
[0074] In addition, conventional CAN bus links generally use a single bus with all modules cascaded on this bus link. However, this invention divides the CAN bus link architecture of the entire automatic ticket gate control system into two links. This is to take into account the real-time transient response of CAN bus control and to avoid malfunctions or delays that could lead to door malfunctions, as well as to avoid consuming CAN bus bandwidth and resources. The main side door module and the secondary side door module are connected by a separate CAN bus, while the electronic control unit, the main side access logic control module, and the CAN bus relay module use another CAN bus link. The two CAN bus links are connected by an RS232 interface.
[0075] It should be noted that the door in the door module of this utility model embodiment can be a flap door or a fan door, etc., and this utility model embodiment does not limit it here.
