Description

Technical Field

[0001] This utility model relates to the field of electronic payment, and in particular to an intelligent voice POS payment device based on terminal collaboration. Background Technology

[0002] Currently, most mainstream POS (Point of Sale) devices require cashiers to perform a series of cumbersome manual operations during transactions. A typical process includes: manually turning on the screen or pressing a function key -> finding and clicking the "Transaction" menu on the interface -> entering the transaction amount using the physical keyboard or touchscreen -> selecting a payment method (such as bank card, QR code payment, etc.) -> prompting the user to swipe their card, insert their card, or show their payment code -> finally completing the transaction.

[0003] The above-mentioned operation involves many steps and is inefficient. Especially during peak transaction periods, the time spent at each step accumulates, leading to longer queue times and a decreased user experience. Furthermore, the entire process is highly dependent on manual operation and cannot be "hands-free" or "semi-automated," making it difficult for cashiers to handle other tasks (such as bagging goods and answering questions). Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose an intelligent voice POS payment device based on terminal collaboration.

[0005] To achieve the aforementioned technical objectives, the technical solution adopted by this utility model is as follows: a smart voice POS payment device based on terminal collaboration, comprising a housing assembly, a control assembly, and a microphone module.

The communication module is communicatively connected to a mobile terminal. The RFID module is electrically connected to the control module and is used to read RFID tag information. The power module provides power to the control module. The microphone module is electrically connected to the communication module and is used to capture audio signals and transmit the audio signals to the communication module.

[0006] Furthermore, the communication module includes a Bluetooth module and a voice module, the Bluetooth module is electrically connected to the voice module, the microphone module is electrically connected to the voice module, and the voice module is electrically connected to one of the I / O interfaces of the control module; It also includes a power amplifier and a speaker module, wherein the power amplifier is electrically connected to the voice module and the speaker module, respectively.

[0007] Furthermore, the control component also includes a display module, which is provided with an I2C interface, and the display module is electrically connected to the control module through the I2C interface.

[0008] Furthermore, the control component also includes multiple button modules, each of which is electrically connected to multiple I / O interfaces on the control module.

[0009] Furthermore, the outer wall of the main body is provided with a plurality of button holes, the button module is placed in the button holes, and one button hole corresponds to one button module.

[0010] Furthermore, the control module is equipped with a USB interface, and the control module is electrically connected to the power module through the USB interface.

All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0019] Please see Figures 1 to 2 This embodiment provides an intelligent voice POS payment device based on terminal collaboration, including a housing component 1, a control component 2 and a microphone module 25. The housing component 1 includes a main body 11, a top plate 12 and a bottom plate 13, which together form a storage chamber. The control component 2 is placed in the storage chamber. The control component 2 includes a control module 21, a communication module 22, a radio frequency identification (RFID) module 23, and a power module 24. The control module 21 is equipped with a UART (Universal Asynchronous Receiver / Transmitter) interface. The control module 21 is electrically connected to the communication module 22 through the UART interface. The communication module 22 is connected to the mobile terminal. The RFID module 23 is electrically connected to the control module 21 and is used to read RFID tag information. The power module 24 is used to provide power to the control module 21. The microphone module 25 is electrically connected to the communication module 22, and the microphone module 25 is used to capture audio signals and transmit the audio signals to the communication module 22.

[0020] The housing assembly 1 is an integrated shell structure composed of a main body 11, a top plate 12, and a bottom plate 13 connected by mechanical means (such as screw fixing or snap-fit ​​splicing). The main body 11 is cylindrical, hollow inside, and open at both ends. The top plate 12 and the bottom plate 13 cover the upper and lower openings of the main body 11, respectively. The main body 11, the top plate 12, and the bottom plate 13 together form a sealed storage chamber to provide housing space for the control component 2 and prevent external interference to the control component 2. The housing assembly 1 is preferably made of high-strength ABS engineering plastic, which has sufficient structural rigidity to resist daily drop impacts. At the same time, the plastic is lightweight, which helps to reduce the overall weight of this POS payment device.

[0021] In this embodiment, the control module 21 is a microcontroller unit (MCU) with low power consumption; the communication module 22 is a data transmission component that supports data interaction and transmits data to the control module 21 via a UART interface; the radio frequency identification (RFID) module 23 is connected to the control module 21 via an SPI interface, and is a tag reading component based on RFID technology, consisting of an RFID chip, an antenna, and a matching circuit, capable of emitting radio frequency signals at specific frequencies (such as 13.56MHz, compatible with financial IC card standards), when an RFID tag (such as a bank card chip, NFC...) is detected... When the device enters the signal coverage area, the tag obtains energy through electromagnetic induction and returns the stored information. The RFID module 23 receives, decodes, and transmits the information to the control module 21, realizing contactless information reading. The power module 24 is a power supply unit composed of a power management chip, filter capacitor, and voltage regulator circuit. It can be powered by a battery or USB and outputs a stable DC voltage (such as 3.3V or 5V) to provide continuous and stable power to all electrical components such as the control module 21 and communication module 22. The microphone module 25 is an audio acquisition unit composed of a microphone sensor, signal filtering circuit, and amplification circuit. The microphone sensor is preferably a MEMS microphone, which has high sensitivity and low noise characteristics and can accurately capture audio signals such as voice and prompts in the environment. After filtering and amplification preprocessing, a stable electrical signal is formed.

[0022] Specifically, the communication module 22 establishes a communication connection (such as Bluetooth or Wi-Fi) with the mobile terminal (such as a mobile APP) to realize command interaction, data transmission, and voice stream synchronization between the POS payment device and the mobile terminal; the microphone module 25 captures audio signals in the environment (such as user voice commands) in real time, converts them into standard electrical signals after internal circuit preprocessing, and transmits them to the communication module 22 through the signal line, and then the communication module 22 forwards them to the mobile terminal, which performs voice recognition processing and returns the voice command result to the communication module 22. The communication module 22 then transmits the voice command to the control module 21 through the UART interface. The control module 21 receives and executes the command, driving the radio frequency identification module 23 to emit radio frequency signals. When the user presents a payment medium with an RFID tag (such as a bank card), the radio frequency identification module 23 quickly identifies the tag information and transmits it to the control module 21, providing an identity verification basis for the payment transaction.

[0023] In this embodiment, the housing assembly 1, through the mechanical enclosure of the main body 11, top plate 12, and bottom plate 13, forms a sealed and robust storage chamber, effectively blocking the influence of external dust, liquids, and collisions on the internal components, ensuring stable operation of the device in complex environments. The communication module 22 works in collaboration with the mobile terminal, transmitting complex voice recognition and semantic parsing tasks to the mobile terminal for processing. This eliminates the need to integrate a high-performance computing chip within the POS device, significantly reducing hardware costs and design complexity. Simultaneously, the microphone module 25 captures voice commands from the user (such as amount, payment method, etc.) and passes them to the communication module 22. After processing by the mobile terminal, the control module 21 executes the commands, driving the radio frequency identification module 23 to complete the transaction. Throughout the process, no manual operation is required; only voice commands are needed, improving operational efficiency and reducing reliance on human intervention.

[0024] In this embodiment, the communication module 22 includes a Bluetooth module and a voice module. The Bluetooth module is electrically connected to the voice module, the microphone module 25 is electrically connected to the voice module, and the voice module is electrically connected to one of the I / O interfaces (Input / Output Interfaces) of the control module 21. It also includes a power amplifier 27 and a speaker module 26, wherein the power amplifier 27 is electrically connected to the voice module and the speaker module 26, respectively.

[0025] The Bluetooth module is designed based on Bluetooth technology (such as Bluetooth 5.0 and BLE Low Energy Bluetooth), integrating a Bluetooth RF chip, antenna, and communication protocol stack. It supports establishing a short-range wireless connection with mobile terminals and enables low-latency transmission of commands, data, and voice streams. The voice module consists of an audio processing chip, filtering circuit, and signal conversion circuit. It has functions such as audio signal preprocessing, format conversion, and signal amplification. It can receive the raw audio signal transmitted by the microphone module 25 and perform noise reduction, filtering, and analog-to-digital conversion, and then transmit the processed audio signal to the Bluetooth module. The Bluetooth module wirelessly transmits the signal to the mobile terminal for semantic and command recognition. At the same time, the voice module is connected to the control module 21 through the IO interface so that it can wake up the POS payment device after detecting an external wake-up word audio. The power amplifier 27 consists of a power amplifier chip, bias circuit, and protection circuit. It can amplify the weak electrical signal output by the voice module to a sufficient power to drive the speaker module 26 to produce sound, enabling the speaker module 26 to clearly play transaction prompts (such as "Please swipe your card"), transaction results (such as "Transaction successful"), and other voice information.

[0026] Bluetooth Low Energy (BLE) can significantly extend the standby time of devices, eliminating the need for frequent charging and making them suitable for long-term continuous use. The wireless connection method also frees devices from the constraints of cables, allowing for more flexible placement and meeting diverse usage scenarios such as retail and catering.

[0027] In this embodiment, the control component 2 further includes a display module 28, and the control module 21 is also provided with an I2C interface. The display module 28 is electrically connected to the control module 21 through the I2C (Inter-Integrated Circuit) interface.

[0028] The display module 28 consists of a display panel, a driver chip, and a backlight circuit. The display panel is preferably an LCD liquid crystal display screen, which has low cost and power consumption and can meet the usage requirements. The display module 28 can intuitively display transaction amount, payment status (success / failure), operation prompts (such as "Please show your bank card"), device system and other related information.

[0029] The display module 28 enables users and operators to quickly verify transaction amounts and confirm payment status via the screen, reducing transaction errors.

[0030] In this embodiment, the control component 2 further includes a plurality of button modules 14, which are electrically connected to a plurality of I / O interfaces on the control module 21.

[0031] The button module 14 consists of physical buttons, trigger circuits, and a rebound structure. The physical buttons can be made of silicone or metal, providing a good pressing feel and rebound performance. The trigger circuit adopts a mechanical contact or capacitive sensing design, which can convert the pressing action into an electrical signal. Each button module 14 corresponds to a specific function (such as power on, increase volume, decrease volume).

[0032] The one-to-one IO interface connection ensures that the operation signal of each button is transmitted independently without signal interference, resulting in fast button response and timely operation feedback, thus improving the user's manual operation experience. The button module 14 allows personnel to directly operate the POS payment device manually, which is faster than voice commands.

[0033] In this embodiment, a plurality of button holes 15 are provided on the outer wall of the main body 11, and the button module 14 is placed in the button hole 15, with one button hole 15 corresponding to one button module 14.

[0034] The button hole 15 is a circular or square hole formed on the outer wall of the main body 11 by mechanical processing (such as drilling or injection molding). The size (diameter and depth) of the hole matches the outer dimensions of the button module 14. The inner wall of the hole is smooth and the edges are rounded to avoid scratching the user's fingers. At the same time, a certain assembly gap is reserved to facilitate the installation and disassembly of the button module 14.

[0035] The button hole 15 can improve the stability of the button module 14 installation, prevent the button from becoming loose or shifting due to long-term pressing, and also protect the button module 14 to prevent damage due to accidental drop of the device, thus extending the service life of the button module 14.

[0036] In this embodiment, the control module 21 is provided with a USB interface, and the control module 21 is electrically connected to the power module 24 through the USB interface.

[0037] The USB interface can be either USB Type-C or Micro-USB, and features hot-swapping and plug-and-play functionality. The interface contains power pins (VCC, GND) and signal pins (D+, D-). The power pins are used to transmit electrical energy, and the signal pins can be used for data transmission or status interaction. The power module 24 provides the device with a 5V voltage and a 500mA current through the USB interface.

[0038] The USB interface has high versatility and is compatible with mainstream power adapters, USB data cables, power banks and other power supply devices on the market. Users do not need to purchase a dedicated power supply, which improves the portability of the device and makes the power supply more flexible.

[0039] In this embodiment, a plurality of LED lights 31 are also included, and the plurality of LED lights 31 are electrically connected to a plurality of IO interfaces on the control module 21 respectively; The outer wall of the main body 11 is provided with a plurality of lamp holes, and the LED lamp 31 is placed in the lamp holes, with one lamp hole corresponding to one LED lamp 31.

[0040] The full name of LED 31 is Light-Emitting Diode, which is a low-power, long-life light-emitting indicator component. It is made of semiconductor light-emitting material and can emit light when driven by current. The color of LED 31 can be selected according to needs (such as red, green, blue, yellow). Each LED 31 corresponds to a specific device working state (such as red indicating a fault, green indicating a successful transaction, and yellow indicating a transaction in progress). The lamp hole is a hole structure formed by mechanical processing on the outer wall of the main body 11. It adopts a circular design and the diameter is adapted to the size of the light-emitting surface of LED 31.

[0041] The LED light 31 features fast response and illumination indication, allowing users and operators to know the working status of the POS payment device without having to look at the screen or wait for voice prompts, so as to quickly proceed to the next step and improve operational efficiency.

[0042] In this embodiment, the control component 2 further includes an anti-tampering module 29, which is electrically connected to the anti-tampering pin on the control module 21.

[0043] The anti-tampering module 29 consists of a tamper detection sensor, a signal processing circuit, and an alarm triggering circuit. The tamper detection sensor can be a mechanical switch (such as a cover opening detection switch), a resistive sensor, or a capacitive sensor to detect whether the device's casing has been illegally opened or whether internal components have been disassembled or replaced. The signal processing circuit filters, amplifies, and converts the signals collected by the sensor. The alarm triggering circuit quickly outputs an alarm signal when tampering is detected. The anti-tampering pin is a dedicated security interface reserved on the control module 21. It is a dedicated channel for secure signal interaction between the control module 21 and the anti-tampering module 29. It has high reliability and anti-interference capabilities and is only used to receive the tamper detection signal from the anti-tampering module 29. It does not participate in other data transmission or command interaction, ensuring the independence and security of secure signal transmission.

[0044] The anti-tampering module 29 enables administrators to promptly detect and address tampered devices, preventing them from being used for transactions and reducing transaction risks.

[0045] In this embodiment, a debugging module 30 is also included, which is electrically connected to one of the UART interfaces on the control module 21.

[0046] The debugging module 30 establishes an independent data link with the control module 21 through a dedicated UART interface. During the device development phase, developers can use the debugging module 30 to burn the written control programs (such as transaction process control programs and voice interaction programs) into the flash memory of the control module 21. At the same time, the debugging module 30 can monitor the operating status of the control module 21 in real time, read internal register data and program running logs, and check for program vulnerabilities. During the device production phase, the debugging module 30 can be used to configure the parameters of the control module 21, such as setting Bluetooth connection parameters, the operating frequency of the RFID module 23, and the indication mode of the LED light 31, so that the device can adapt to different usage scenarios. During the use of the device, when a fault occurs (such as transaction failure or no voice response), maintenance personnel can use the debugging module 30 to read the fault logs and error codes of the control module 21, quickly locate the cause of the fault (such as program crash or hardware failure), and repair it, which greatly reduces the difficulty of program development, fault diagnosis time and maintenance costs, and improves development and maintenance efficiency.

[0047] The workflow of this utility model is as follows: The voice module of the POS payment device continuously monitors ambient sound in standby mode. When it detects a preset wake-up word, the voice module sends a wake-up signal to the control module 21 via the IO interface (e.g., ...). Figure 2 Upon receiving the "Wake up" message, the control module 21 is awakened and responds. The Bluetooth module then sends a "wake-up notification message" to the paired mobile terminal (mobile app). Upon receiving the "wake-up notification message," the mobile terminal immediately sends a "start recording and transmission command" to the POS terminal via Bluetooth. The control module 21 activates the microphone module 25 for high-precision audio acquisition and continuously sends the acquired real-time voice stream data to the mobile app via Bluetooth. The mobile app packages the received voice stream data, calls the API of the cloud-based ASR service for recognition, and the cloud-based ASR service returns the recognition result (text) to the mobile app. The mobile app parses the text content, extracts key transaction parameters (such as amount and payment method), and sends a "start transaction command" to the POS terminal via Bluetooth. This command contains the transaction amount and payment method. Upon receiving the command, the POS terminal immediately activates the RFID module 23 and enters card-finding mode. When the user presents their bank card, the POS terminal detects the card and executes the standard financial transaction process (card reading, encryption, interaction with the payment backend, etc.). After a successful transaction, the payment result is first sent to the mobile app. The mobile app then sends the text to be read (e.g., "Transaction successful, amount: 100 yuan") to the cloud-based TTS service, requesting the generation of an audio file. Upon receiving the audio file (e.g., in MP3 format) from the cloud, the mobile app sends it completely to the POS terminal via Bluetooth. The POS terminal receives and caches the audio file, then plays it aloud through the speaker module 26. Finally, after completing the playback, the POS terminal automatically resets and returns to a low-power listening state.

[0048] In this invention, the microphone module 25 captures voice commands from the user (such as amount, payment method, etc.) and passes them to the communication module 22. After processing by the mobile terminal, the control module 21 begins to execute the commands, driving the radio frequency identification module 23 to operate and complete the transaction. Throughout the process, no manual operation is required; only voice commands are needed, which improves operational efficiency and reduces reliance on human intervention. At the same time, the voice recognition task, which requires a lot of computation, is handled by the mobile terminal and the cloud, greatly reducing the hardware cost and design complexity of the POS terminal itself.

[0049] The above description is only a part of the embodiments of this utility model, and does not limit the scope of protection of this utility model. Any equivalent device or equivalent process transformation made based on the content of this utility model specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this utility model.
