By adding a pass logic control module on the secondary side, various indicator lights on the secondary side and the receiving position / maintenance switch are controlled.

[0044] Figure 3 A schematic diagram of another automatic ticket gate control system provided by the present invention is shown in FIG. 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 figure), a power module, a main side traffic logic control module, a main side door module and a main side switch.

[0046] The power module converts the external power supply, outputs 5V, 12V, 24V, 48V power to each module on the main side, and connects to the power adapter board through the power supply line, and the power adapter board outputs 5V, 12V, 24V, 48V power to each module on the secondary side. The electronic control unit is connected to the power module through the RS232 interface, controls each group of outputs of the power module, collects information such as temperature, current, voltage, etc. of the power module, and performs feedback control on the power module.

[0047] The electronic control unit integrates a face recognition module and a ticket reader / writer module. The face recognition module is connected to the primary face recognition camera module and the secondary face recognition camera module via a USB interface. The ticket reader / writer module is connected to the primary ticket reader / writer antenna (antenna 1 in the figure) and the secondary ticket reader / writer antenna (antenna 2 in the figure). Traditional electronic control units such as Advantech and EVOC's industrial computer series are based on the Intel platform. Currently, face recognition terminals and readers are based on the RK3399 platform architecture, and the RK platform can run the Linux system. Therefore, the electronic control unit of the present invention adopts the RK platform, selects a CPU more powerful than RK3399, such as 3588, 4-core Cortex-A76 + 4-core Cortex-A55 size core architecture, has powerful data computing capabilities, and its built-in 6T computing power NPU integrates Rockchip's fourth-generation artificial intelligence computing engine, supports INT4 / INT8 / INT16 / FP16 mixed computing, supports conversion of network models based on a series of frameworks such as TensorFlow / MXNet / PyTorch / Caffe, and is suitable for various complex AI computing tasks. The electronic control unit is configured to integrate the algorithms of face recognition and ticket reading and writing into the electronic control unit on the basis of normal operation, so that the electronic control unit, face recognition terminal, and ticket reader module are three-in-one.

[0048] The main side switch is connected to the main side access logic control module, the electronic control unit and the main side door module respectively. The electronic control unit is connected to the main side switch via Ethernet. The electronic control unit acts as the master control and exchanges information with the main side access logic control module and the main side door module through the switch.

[0049] The main side passage logic control module is connected to the main side direction indicator light, card swiping indicator light, passage indicator light, guide indicator light 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 in-place switches. It outputs control signals to control the main side indicator lights, receives input signals from the main side in-place switches, and feeds back to the electronic control unit.

[0050] The secondary side includes a secondary side passage logic control module, a power adapter board, a secondary side door module and a secondary side switch.

[0051] The power module is connected to the power adapter board through a power cable to convert the voltage output by the power module into the voltage required by each module on the secondary side. The power adapter board is respectively connected to the secondary side access logic control module, the secondary side gate module and the secondary side switch to supply power to the secondary side access logic control module, the secondary side gate module and the secondary side switch.

[0052] The secondary side switch is connected to the secondary side passage logic control module, the primary side switch and the secondary side door module respectively. The electronic control unit exchanges information with the secondary side passage logic control module and the secondary side door module through the primary side switch and the secondary side switch.

[0053] The secondary side passage logic control module is connected to the secondary side direction indicator light, card swiping indicator light, passage indicator light, guide indicator light 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 in-place switches. It outputs control signals to control the secondary side indicator lights, receives input signals from the secondary side in-place switches, and feeds back to the electronic control unit through the main side passage logic control module.

[0054] The main side also includes a one-way ticket recovery module, which is connected to the electronic control unit via an RS232 interface.

[0055] The electronic control unit is also integrated with a power amplifier module (the power amplifier in the figure), which is used to connect to a speaker, and the speaker can broadcast prompt information to the user. Due to the versatility of traditional electronic control units, power amplifier modules above 15W are not considered to be integrated, and the automatic ticket gate control system usually requires the decibel number to reach 50 decibels within 0.5m from the equipment, which requires the system to have a power amplifier of more than 15W. The audio signal can be amplified and output to the speaker by using TDA7297. However, the existing automatic ticket gate control system has many modules and a common power supply, which generates common ground noise that affects the user experience. Adding an audio isolator between the power amplifier and the speaker will complicate the electrical design. The present invention adds an audio transformer to the output end of TDA7297, which is small in size and low in cost.

[0056] The main side also includes a main side QR code module, the secondary side also includes a secondary side QR code module, and the electronic control unit is also connected to the main side QR code module and the secondary side QR code module through an RS232 interface. Exemplarily, the main side QR code module is used to scan the QR code presented by the user and upload it to the electronic control unit, which processes the QR code, identifies the user's traffic account, and determines the account balance. When the balance is sufficient, the electronic control unit sends an instruction to the main side door module through the main side switch to control the main side door to open. The secondary side QR code module is used to scan the QR code presented by the user and upload it to the electronic control unit, which processes the QR code, identifies the user's traffic account, and determines the account balance. When the balance is sufficient, the electronic control unit sends an instruction to the secondary side door module through the main side switch and the secondary side switch to control the secondary side door to open.

[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 through 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. The traditional automatic ticket gate control system detects through 16-18 pairs of through-beam sensors on the fuselage, which is equivalent to a resolution of 16-18 points (one-dimensional space detection). The through-beam sensors need to be arranged on both the main side and the secondary side, occupying nearly half of the electrical connections in the power supply and control lines of the automatic ticket gate control system. The present invention uses a visual access module to replace the original through-beam sensor, which only needs to be connected to the electronic control unit on the main side through power supply and communication lines. The electrical design has been greatly simplified, and the detection space has been upgraded to three dimensions.

[0059] Figure 4 A structural diagram of a visual access module provided by the present invention is shown in FIG. Figure 4As shown, the visual access module includes a laser projector, a TOF sensor, a color image sensor, a visual processor and a logic processor. The laser projector, the TOF sensor and the color image sensor are all connected to the visual processor, the visual processor is connected to the logic processor (RK3568 in the figure), and the logic processor is connected to the access logic control module. Among them, the laser projector is a modulated collimated laser and acts as a transmitter, and the shutter of the laser projector is controlled by the visual processor. As a receiver, the TOF sensor usually uses a single photodiode to obtain a complete scene depth map or depth data through a one-time imaging technology. The color image sensor collects color images (RGB images). The color image sensor component provides internal parameters, external parameters, and distortion parameters. The visual processor can use a high-real-time FPGA or an unmanned driving field horizon processor to output 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 angle and strong anti-light interference ability, which is suitable for use in stations with limited height or non-underground stations.

[0060] Figure 5 A structural diagram of another visual access module provided by the present invention is shown in FIG. Figure 5 As shown, the visual access module includes a laser projector, a structured light sensor, a color image sensor, a visual processor and a logic processor (RK3568 in the figure). The laser projector, the structured light sensor and the color image sensor are all connected to the visual processor, the visual processor is connected to the logic processor, and the logic processor is connected to the access logic control module. The structured light sensor is divided into left and right infrared image sensors. The active binocular depth camera supports receiving instructions from the logic processor through the USB interface or Ethernet interface to realize software instruction triggering image acquisition; the camera with a hardware trigger interface supports external hardware signal triggering and acquires images according to the frequency of the trigger signal (≤ the frame rate of the continuous mode). The laser projector emits structured light to the surface of the object to be measured, the color image sensor collects RGB data, and after the infrared image sensor receives two channels of infrared data, it uses the embedded visual processor as the computing platform to quickly calculate the depth data of each point in the field of view according to the principle of triangulation. Since the image data output by the color image sensor needs to be synchronized with the infrared image data, the color image sensor without the hardware ISP module is selected to output the RAW BAYER image. There may be color cast on the image screen, which needs to be processed by the SDK software ISP (such as white balance). After processing, it is displayed as a color image in the normal color space. The advantage of the 3D structured light vision access module is that the depth data is stable and the cost is low, which is suitable for a large number of underground stations.

[0061] The visual access module in the present invention can accurately calculate the current position information of the target, and judge whether the target is a person or an object, distinguish whether the person is an adult or a child, and track and judge multiple moving targets at the same time. However, the depth map will have certain errors for people or objects or the combination of people and objects in irregular states, such as: a person stretches his arms to open the gate, the effective contour information of the whole person; a person passes the gate with a baby stroller, the effective contour information of the person and the baby stroller combined; a person passes the gate with an umbrella, the effective contour information of the person and the umbrella combined, etc. In response to this problem, the present invention can calculate the current position information and height information of the target through the depth image, judge whether the target is a person or an object, track and judge multiple targets at the same time, and track and identify the situation of passengers following. Then, the RGB image is used to judge whether the passenger is an adult or a child, whether there is a pregnant woman among the adults, whether the object is a trolley case or a baby stroller or a wheelchair or a hat or an umbrella, and the combination of people and objects includes passengers carrying trolley cases, passengers pushing baby strollers and judging whether there is a baby in the baby stroller, passengers pushing wheelchairs and judging whether there is someone in the car, passengers wearing hats, and passengers holding umbrellas. Then the area information where the people and objects are located is given to the access logic control board for behavior recognition and judgment.

[0062] In an embodiment of the present invention, both the main side door module and the auxiliary side door module are integrated with a motor drive unit and a door machine. The existing door module includes a mechanical part and a motor part. The motor drive module controls the rotation of the motor in the door mechanism, and the control line between the two includes a power line (three-phase U, V, W) and a feedback line (encoding line / Hall signal). The present invention combines the motor drive unit and the door machine into one. Integrating the motor drive unit into the motor can save the power line and feedback line in the electrical design. There is no need for an external drive control system assembly shell, which saves the wiring space between the motor and the drive. The external interface of the entire door module only has power supply and communication terminals, which saves costs. The integrated motor can effectively reduce the failure rate of the entire door module equipment.

[0063] Figure 6 A schematic diagram of another automatic ticket gate control system provided by the present invention is shown in FIG. Figure 6 As shown, the same parts of this embodiment as those in the previous embodiment are not described in detail here. The difference between this embodiment and the previous embodiment is as follows:

[0064] The electronic control unit is connected to the main side access logic control module through the industrial Ethernet bus (EtherCAT) (EtherCAT is represented by ECAT in the figure), and the main side access logic control module is connected to the main side door module through the EtherCAT bus. The electronic control unit (ECU in the figure) is connected to the secondary side access logic control module through the EtherCAT bus, and the secondary side access logic control module is connected to the secondary side door module through the EtherCAT bus.

[0065] Each module in the above-mentioned embodiment is networked according to the Ethernet mode, and its network delay is less than 100mS, which meets most application occasions. However, for occasions with higher real-time requirements, an industrial Ethernet bus with better real-time performance is required. The EtherCAT bus retains the standard Ethernet physical layer and builds a new deterministic protocol on its basis. This protocol uses a host controller, which is the only device that allows the creation of EtherCAT frames. The length of the frame is always the same, and each device node on the network has a dedicated frame addressable area. When the frame is transmitted in the network, each node selects control data and discards the reply information in its allocated space when it passes. The delay of the frame does not exceed the hardware transmission delay, and at the same time provides a maximum effective data rate close to the 100Mbps line speed, so that the real-time performance of the network reaches the μS level. EtherCAT bus technology is directly implemented on the Ethernet hardware platform through a master-slave mode. The short cycle time is because the microprocessor of the slave station does not need to process Ethernet packets. EtherCAT uses a full-duplex Ethernet physical layer, and the slave station may have two or more ports. If the device does not detect other devices downstream, the controller of the slave station will automatically close the corresponding port and return the Ethernet frame. Therefore, EtherCAT supports almost all network topologies, including bus, tree or star. The topology of EtherCAT can be any combination of network lines, branches or short lines.

[0066] The characteristics of the EtherCAT bus determine that the electronic control unit in the present invention serves as the master station, and the modules on the master and slave sides serve as slave stations, without the need to pass through a switch in the middle, so that the switches on the master and slave sides in the automatic ticket gate control system can be omitted. In the industrial automation industry, it is usually required that the equipment on the bus operates uninterruptedly, and production is not allowed to be stopped. Redundancy technology can achieve the reliability and stability of the application system. Therefore, the present invention designs the communication line between the master and slave devices into a ring structure with two branches, realizing the link redundancy function. When a cable is broken, the two links control and continue to work. At the same time, EtherCAT can automatically detect the fault point in the bus system, which can greatly simplify the maintenance of the system and improve the maintainability of the equipment.

[0067] The specific system structure is as follows Figure 6As shown, the 5V, 12V, 24V, and 48V power supplies output by the power module are used to supply power to each module on the main side and are connected to the power adapter board on the secondary side through the 12V, 24V, and 48V power supply lines (since the switch on the secondary side is cancelled, the 5V power supply does not need to be passed through the machine), and the power adapter board outputs 12V, 24V, and 48V power supplies to supply power to each module on the secondary side. The electronic control unit is connected to the power module, the one-way ticket recovery module, the main side QR code module, and the secondary side QR code module through the RS232 interface, and is connected to the main side face recognition camera module and the secondary side face recognition camera module through the USB interface, and is connected to the main side ticket reading and writing antenna and the secondary side ticket reading and writing antenna through the antenna feeder, and is connected to the main side display screen and the secondary side display screen through VGA / HDMI, and is connected to the external network through the Ethernet port, and is connected to the speaker through the power amplifier output. The electronic control unit is connected to the main side passage logic control module through the EtherCAT bus, the main side passage logic control module is connected to the main side door module through the EtherCAT bus, the main side door module is connected to the visual passage module through the EtherCAT bus, the visual passage module is connected to the secondary side door module through the EtherCAT bus, the secondary side door module is connected to the secondary side passage logic control module through the EtherCAT bus, and the secondary side passage logic control module is connected to the electronic control unit through the EtherCAT bus.

[0068] Figure 7 A schematic diagram of another automatic ticket gate control system provided by the present invention is shown in FIG. Figure 7 As shown, the same parts of this embodiment as those in the previous embodiment are not described in detail here. The difference between this embodiment and the previous embodiment is as follows:

[0069] The secondary side passage 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, the CAN bus relay module is connected to the primary side passage logic control module via the CAN bus, and the primary side door module is connected to the secondary side 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 using CAN communication can also meet most usage scenarios and has lower costs. The existing old modules on site also support the 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 5V, 12V, 24V, and 48V power supplies output by the power module are used to supply power to each module on the main side and are connected to the CAN bus relay module on the secondary side through the 12V, 24V, and 48V power supply lines (since the switch on the secondary side is cancelled, the 5V power supply does not need to be passed through the machine), and the CAN bus relay module on the secondary side outputs 12V, 24V, and 48V power supplies to supply power to each module on the secondary side. The electronic control unit (ECU in the figure) is connected to the power module, the one-way ticket recovery module, the main side QR code module, and the secondary side QR code module through the RS232 interface, and is connected to the main side face recognition camera module and the secondary side face recognition camera module through the USB interface, and is connected to the main side ticket reading and writing antenna and the secondary side ticket reading and writing antenna through the antenna feeder, and is connected to the main side display screen and the secondary side display screen through VGA / HDMI, and is connected to the external network through the Ethernet port, and is connected to the speaker through the power amplifier output, and is connected to the main side pass logic control module through the CAN bus. The main side passage logic control module is connected to the main side door module through the RS232 interface, is connected to the visual passage module through the RS485 interface, is connected to the secondary side CAN bus relay module through the CAN bus, is connected to the main side direction indicator light, card swiping indicator light, passage indicator light, guide indicator light 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 in-place switches; the secondary side CAN bus relay module is connected to the secondary side direction indicator light, card swiping indicator light, passage indicator light, guide indicator light and other indicator lights, and is connected to the secondary side maintenance door switch, top cover switch, ticket box switch and other in-place switches; the main side door module is connected to the secondary side door module through a separate CAN bus.

[0072] This embodiment simplifies and integrates the power adapter board and the secondary side traffic logic control module into one. The secondary side traffic logic control module is equipped with multiple communication interfaces (including RS232, RS485, CAN, Ethernet) to cope with the communication of different devices, and the communication on the secondary side only needs to meet CAN. Therefore, the original secondary side traffic logic control module can be simplified into a CAN bus relay module, which communicates with the main side traffic logic control module, parses the control instructions of the main side traffic logic control module, and controls each indicator light.

[0073] Due to the fusion of the modules on the primary and secondary sides mentioned above, the modules on the secondary side have been simplified a lot. Only the secondary door module, CAN bus relay module and secondary display screen need to be powered. After the number of interfaces is reduced, the functions can be directly integrated into the CAN bus relay module.

[0074] In addition, conventional CAN bus links generally use one bus, and each module is cascaded on this bus link. The present invention divides the CAN bus link architecture of the entire automatic ticket gate control system into two. This is to take into account the real-time transient response of the CAN bus control and to avoid malfunction or action delay that causes door malfunction, to avoid occupying CAN bus bandwidth and resources. The main side door module and the auxiliary side door module are connected separately using the CAN bus, and the electronic control unit, the main side passage logic control module, and the CAN bus relay module use another CAN bus link. The two CAN bus links are connected with an RS232 interface.

[0075] It should be noted that the door in the door module in the embodiment of the present invention may be a flap door or a leaf door, etc., and the embodiment of the present invention does not limit this.
