Recently, Twowin technology has cooperated deeply with a leading American technology company, and with the self-developed smart box T201S as the core, it has successfully created an AI vending machine that integrates image recognition and behavior analysis detection technology to help the American technology company’s project land smoothly.

This achievement demonstrates Twowin technology’s deep technical accumulation in the field of artificial intelligence. Through accurate image recognition and intelligent behavior analysis, the AI ​​vending machine can provide users with a more convenient and efficient shopping experience, and also bring higher operational efficiency and data insights to operators.

The AI ​​vending machine project developed by Twowin technology and its friends has not only landed in the United States, but will also gradually radiate the global market from this point on, bringing new changes and opportunities to the global retail market through intelligent shopping experience and efficient operation mode.

2.Solution

This solution uses T201S smart box to connect “cargo aisle control board + USB stereo camera + screen display + 4-way microphone + optical sensor + card reader + LED light + smart door lock”, integrating multiple sensors and devices to form an intelligent vending machine system.

1. T201S smart box

Core function: T201S smart box is the “brain” of the entire system, responsible for data processing, AI algorithm operation, and communication and coordination between devices.

It uses the USB interface to connect the stereo camera to accurately complete image acquisition and analysis; connects the cargo aisle control board, optical sensor, LED light and smart door lock through the GPIO interface to achieve precise control of various hardware devices; uses the audio interface to connect 4-way microphones to provide users with smooth voice recognition and interactive experience; at the same time, connects the screen display through the HDMI interface to clearly present the user interface and support convenient interaction.

2. Cargo aisle control board

Function: Control the mechanical movement of the cargo aisle to ensure that the goods can be shipped accurately.

The cargo aisle control board is connected to the T201S smart box through the GPIO interface to receive control instructions from the smart box. The AI ​​algorithm sends instructions to the cargo channel control board through the smart box according to the goods selected by the user, drives the motor or mechanical device, and ensures the smooth shipment of the goods.

3. USB stereo camera

Function: used to capture user behavior and product images, and supports AI algorithms for image recognition and behavior analysis.

The stereo camera is connected to the T201S smart box through the USB interface to transmit image data in real time. The AI ​​algorithm processes the image to identify user actions (such as picking up and putting goods) and product information (such as product type and quantity). Through the deep learning model, the system can detect abnormal behavior (such as theft or wrong operation) in real time and trigger an alarm.

4. Screen display

Function: used for user interface display, supporting product display, operation prompts and advertising playback.

The screen display is connected to the T201S smart box through the HDMI interface to receive the image and video signals transmitted by the smart box. The AI ​​algorithm dynamically updates the display content according to user operations and system status, such as product recommendations, payment prompts, etc.

5. 4-way microphone

Function: used for voice interaction, supporting voice recognition and voice command processing.

The microphone is connected to the T201S smart box through the audio interface to collect user voice data. The AI ​​voice recognition algorithm processes the voice signal and recognizes the user’s voice commands (such as querying product information and requesting help). The system responds to the voice command, such as displaying information on the screen or voice feedback.

6. Optical sensor

Function: used to detect the removal and placement of goods, and assist the image recognition system.

The optical sensor is connected to the T201S smart box through the GPIO interface to monitor the status of the cargo channel in real time. When the user takes out or puts in the goods, the optical sensor detects the change and triggers a signal. The AI ​​algorithm combines the optical sensor data and image recognition results to ensure the accuracy of commodity counting and inventory management.

7. Credit card machine

Function: used for user payment, supporting multiple payment methods such as credit cards and debit cards.

The credit card machine is connected to the T201S smart box through a serial interface or a USB interface. After the user swipes the card, the card machine transmits the payment information to the smart box, and the smart box sends the payment request to the payment gateway through the network; after the payment is successful, the smart box triggers the cargo channel control board to ship and updates the inventory information.

8.LED light

Function: used to indicate status (such as out-of-stock goods, system failure) and guide user operation.

The LED light is connected to the T201S smart box through the GPIO interface and receives the control signal of the smart box. The AI ​​algorithm controls the color and flashing mode of the LED light according to the system status (such as sold out goods, abnormal operation), providing intuitive feedback to users.

9.Smart door lock

Function: used to control the opening and closing of the vending machine cabinet door to ensure safety.

The smart door lock is connected to the T201S smart box through the GPIO interface and receives the control instructions of the smart box. The AI ​​algorithm controls the opening and closing of the door lock according to the user’s identity authentication results (such as card swiping, fingerprint recognition). The door lock status is fed back to the smart box to ensure the safe operation of the system.

Solution advantages

1. Good intelligent interactive experience: integrated image recognition, behavior analysis, and voice interaction technology, allowing users to shop naturally and accurately; with convenient payment, smart door locks, and LED lights and screen guidance functions, it improves the convenience and experience of shopping in all aspects.
2. Precise control and high efficiency: Through precise inventory management, the quantity and location of goods can be mastered in real time; the automated delivery system reduces the failure rate and improves the delivery speed; the abnormal behavior detection and alarm function escorts the safety of operation.
3. Data insight and decision-making: The system collects and deeply analyzes operational data, and has insights into user purchase preferences and product sales trends, so as to adjust the layout, inventory and marketing plans in a targeted manner and improve operational efficiency.
4. Flexible customization and strong adaptability: Under the modular design concept, each functional module can be independently developed and upgraded, and can be customized according to different business scenarios and user needs, and quickly adapt to business changes.
5. Cost-effective and easy to promote: Adopting a cost-effective design solution, it effectively reduces the cost of procurement, deployment and maintenance; at the same time, it complies with international standards, supports multiple languages, and is suitable for global market promotion.
