[0022] This utility model discloses an integrated card reader device, comprising a module body and a card reader antenna 2. The module body includes a housing structure 1 and a main control unit, a read / write module, and a communication unit integrated within the housing 1. The card reader antenna 2 is connected to the main control unit via a coaxial cable. The communication unit includes a 4G / 5G communication module and an RS232 serial port module 12. The RS232 serial port module 12 is used for electrical connection with an external turnstile, and the 4G / 5G communication module is used for electrical connection with the Beijing Smart Card platform. The 4G / 5G communication module and the RS232 serial port module 12 are respectively electrically connected to the main control unit, and the read / write module is electrically connected to the main control unit. The housing structure is a rectangular prism with precisely designed dimensions of 160mm in length, 125mm in width, and 50mm in height. Four mounting screw holes 3 are evenly distributed at the four corners of the bottom of the housing 1. The screw holes 3 are rectangular in shape, extending 10mm laterally from the edge of the module body, and have chamfered edges around them. The housing 1 can be securely fixed inside the gate through the screw hole 3, preventing the module from shifting due to vibration during the operation of the gate.

[0023] Reference Figure 1 As shown, the front of the housing integrates multiple interfaces, including an RJ45 network port 11, an RS232 serial port module 12, a USB1 interface 13, a USB2 interface 14, a program download interface 15, a power interface 16, and a program debugging interface 17. These interfaces are arranged orderly along the edge of the module body with reasonable spacing, facilitating wiring during gate installation and preventing signal interference between interfaces. The module body has clearly defined unit installation areas. The main control unit, read / write module, communication unit, and QR code scanning unit are respectively fixed on pre-set circuit boards. The units are connected by wires, with neat wiring routes to reduce signal transmission loss.

[0024] The RJ45 network port 11 can be connected via Ethernet cable as a backup network to ensure data transmission when the 4G / 5G communication module malfunctions. The program download interface 15 is used to connect to a computer via a dedicated data cable to download new programs to the main control unit. The program debugging interface 17 is used to debug the program running inside the housing 1.

[0025] As one specific embodiment, such as Figure 2 As shown, the card reader antenna 2 has a plate-like structure and adopts an RF antenna design adapted for contactless card recognition. Its effective recognition range covers the card swiping area of ​​the gate, ensuring stable recognition of users within the normal card swiping distance. An antenna interface 18 is provided on the housing 1. The card reader antenna 2 is connected to the housing 1 via a coaxial cable approximately 90 cm long. One end of the coaxial cable is connected to the antenna interface 18 on the housing 1 via an RF interface, and the other end extends to the center of the front of the card reader antenna 2 and is fixed there. This connection method reduces the attenuation of the RF signal during transmission, ensuring the integrity of the card reading data. During actual installation, the card reader antenna 2 needs to be fixed to the card swiping sensing area of ​​the gate. The recommended minimum distance between its front and the card when the user swipes is 0.5 cm. This distance ensures recognition sensitivity while avoiding interference from external metal parts on the antenna signal. The size of the antenna plate is adapted to the size of the gate's sensing area, ensuring no blind spots in the recognition range while not occupying excessive internal space of the gate.

[0026] like Figure 3 As shown, in one specific embodiment, the main control unit is the core data processing module of the module, including an MCU chip, a storage module, a real-time clock module, and a SOC chip. The components work together to realize the functions of data reception, processing, storage, and time synchronization.

[0027] Specifically, the MCU chip used is a quad-core chip, model N32G455REL7, with a main frequency of 1.1GHz. This chip has strong data processing capabilities and can quickly receive and parse card reading data, barcode scanning data, and gate feedback data. The MCU chip is electrically connected to the RS232 serial port module 12, the read / write module, the storage module, the real-time clock module, and the SOC chip via wires. The connection between the MCU chip and the RS232 serial port module is used to output gate control signals; the connection with the read / write module is used to receive card reading data; the connection with the storage module is used for temporary data storage; the connection with the real-time clock module is used to obtain time information; and the connection with the SOC chip is used for collaborative processing of complex data.

[0028] In this example, the storage module is configured with 1GB of RAM and 8GB of storage. The 1GB of RAM is used as a temporary data cache when the MCU chip processes data, and the 8GB of storage is used to store the parameter configurations and historical transaction data required for module operation for a long time. The storage module is electrically connected to the MCU chip via a data bus.

[0029] In this example, the real-time clock module has a built-in independent clock battery. Even if the module is powered off, the clock battery can still maintain the module's timekeeping operation, ensuring that time information is not lost. The module's time error is ±10 seconds / 24 hours. After powering on, it can automatically synchronize with the base station time, obtaining the base station time signal through the 4G / 5G communication module to achieve time calibration. The real-time clock module is electrically connected to the MCU chip via the I2C bus, and can transmit the current time information to the MCU chip in real time. This time information will be uploaded to the Beijing Smart Card platform along with transaction data for timestamp marking of transaction records.

[0030] In this example, the SOC chip selected is the SC200L model, whose main function is to assist the MCU chip in processing QR code scanning data and 4G / 5G communication data. Since QR code data parsing and 4G / 5G network data transmission require high processing speeds, the SOC chip can alleviate the processing pressure on the MCU chip, improving overall data processing efficiency. The SOC chip is electrically connected to the MCU chip via a high-speed data interface, and also electrically connected to the QR code scanning unit and the 4G / 5G communication module. It can directly receive the raw scanning data transmitted by the QR code scanning unit and the platform interaction data transmitted by the 4G / 5G module, preprocess it, and then transmit it to the MCU chip for final processing, reducing data processing latency.

[0031] In one specific embodiment, the read / write module includes four PSAM card slots and a reader / writer. The reader / writer is used to read contactless card data sensed by the card reader antenna 2. It supports Mifare cards and CPU cards conforming to the ISO / IEC 14443 Type A / Type B protocol, and is also compatible with second-generation ID cards and third-generation social security cards. Its model is SS728M, meeting the compatibility and recognition requirements of various card types. The four PSAM card slots are fixed in a row on the side of the read / write module. The slots conform to the ISO7816 standard and are electrically connected to the main control unit. The PSAM cards are encrypted cards; after being inserted into the slots, they encrypt the card data read by the read / write module, ensuring the security of transaction data and preventing data tampering during transmission. The four PSAM card slots can each hold a PSAM card with a different key, adapting to the encryption requirements of different card types and improving the module's encryption flexibility.

[0032] In one specific embodiment, the communication unit includes a 4G / 5G communication module and an RS232 serial port module, which respectively enable remote communication with the Beijing Smart Card platform and local communication with external turnstiles.

[0033] Specifically, the 4G / 5G communication module supports 4G full network compatibility and 5G network access, and can automatically switch network modes according to the network coverage of the gate installation scenario to ensure a stable connection with the Beijing Smart Card platform. Module 1 has one SIM card slot, shaped to fit Micro SIM cards. The SIM card slot is electrically connected to the 4G / 5G communication module; inserting a carrier SIM card enables network access. The 4G / 5G communication module is electrically connected to the SOC chip of the main control unit via a data interface, receiving transaction data transmitted by the main control unit and uploading the data to the Beijing Smart Card platform via the 4G / 5G network.

[0034] One end of the RS232 serial port module 12 is electrically connected to the external gate, and the other end is electrically connected to the MCU chip of the main control unit. When the MCU chip determines that the card reading data is valid, it will send a gate opening and closing control signal to the RS232 serial port module 12. The signal is transmitted to the gate through the serial port module 12 to control the gate to open.

[0035] like Figure 1 As shown, the front of the housing 1 also includes a barcode scanner interface 19 for connecting to the QR code scanning unit inside the housing 1. This unit's scanning range covers the QR code recognition area of ​​the gate and can recognize electronic QR codes generated by the Beijing Yikatong APP and other compatible payment QR codes. The output of the QR code scanning unit is electrically connected to the SOC chip of the main control unit via a data cable. When a user presents a QR code and approaches the scanning area, the scanner can quickly recognize the QR code image and parse it into raw data. After the raw data is transmitted to the SOC chip, it undergoes preprocessing before being transmitted to the MCU chip for validity determination. If valid, the MCU chip also controls the gate's opening and closing via the RS232 serial port module 12 and uploads the scanned transaction data to the Beijing Yikatong platform.

[0036] In one specific embodiment, the housing 1 houses a power supply unit that provides a stable power supply to all power-consuming units within the module. Its input terminal is connected via a power interface 19 on the module body. The power supply unit contains a voltage conversion circuit that converts the input DC voltage into the operating voltage required by each unit, and then electrically connects it to the main control unit, read / write module, communication unit, and QR code scanning unit via wires.

[0037] When a user swipes a card or scans a QR code at the turnstile, the module's workflow is as follows: For card swiping, the user brings the card close to the turnstile's swiping area. The card reader antenna 2 senses the card signal and transmits it to the read / write module via a coaxial cable. The read / write module reads the card data and encrypts it through the PSAM card slot. The encrypted data is then transmitted to the MCU chip in the main control unit. For QR code scanning, the user presents a QR code. The QR code scanning unit recognizes and parses the QR code data, transmitting the raw data to the SOC chip for preprocessing before transmitting it to the MCU chip. The MCU chip receives the data and uses pre-stored recognition rules in the storage module to determine its validity. If valid, the MCU chip generates a turnstile opening / closing control signal, which is transmitted to the turnstile via the RS232 serial port module 12 to open the turnstile. If invalid, no control signal is sent. Simultaneously, the MCU chip transmits the transaction data to the SOC chip, which processes it and uploads it to the Beijing Smart Card platform via a 4G / 5G communication module. Meanwhile, the MCU chip temporarily stores transaction data in the storage module. If data upload fails due to network issues, the storage module can temporarily store the data. Once the network is restored, the 4G / 5G communication module will automatically re-upload the data, ensuring no data loss. After the gate opens, the verification result is fed back to the MCU chip via the RS232 serial port module 12. The MCU chip updates the transaction status based on the feedback result and uploads the final transaction status back to the Beijing Smart Card platform, completing the entire transaction process.
