Description

Technical Field

[0001] The present invention relates to the field of retail terminals, and in particular to a smart vending machine master control device, equipment and storage medium with an AI camera. Background Art

[0002] As a new type of retail terminal, the smart vending machine's user process is to scan the code - open the door - select the product - close the door.

[0003] The technology currently used in smart vending machines is to use network cameras to collect videos, which are then processed on the main control of the smart vending machine and uploaded to the cloud server after processing. However, the existing method has the following problems: network cameras are prone to frame drops during video collection and the collection clarity is not good. At the same time, in terms of price cost, network cameras are relatively expensive and not cost-effective.

[0004] On the other hand, the existing smart vending machine main controller is not waterproof enough. A little rain will cause water to accumulate in the main board. The vending machine main controller has shortcomings in processing 4G signals, resulting in poor signal stability. Finally, the original smart after-sales cabinet main controller has shortcomings in board design. The main controller cannot be directly installed on the light box of the smart vending machine in terms of structure. Summary of the invention

[0009] Furthermore, the main control circuit board is fixedly arranged in the main control box through a waterproof cover plate.

[0010] Furthermore, the main control box is also provided with a mounting hole for fixed connection with the smart vending cabinet light box.

[0011] Furthermore, the AI ​​main control unit includes a main control MCU and a main control NPU.

[0012] Furthermore, the master MCU obtains the dual MIPI camera video data and transmits it to the master NPU for processing.

[0013] Furthermore, the main control NPU uses the AIQ algorithm to process the video data and transmits the processed data to the cloud server via the RF coaxial connector.

[0014] The main control circuit board also includes an indicator light for indicating the working status of the main control circuit board.

[0015] The beneficial effects provided by the present invention are: facilitating installation on the smart vending cabinet light box; solving the problem of water ingress during rain that damages the AI ​​main control; adopting a new RF coaxial connector to solve the problem of unstable 4G signals; solving the problem of frame drop and unclear video acquisition, while also greatly reducing costs; adopting the AIQ algorithm to solve the impact of the external environment on the MIPI camera; adopting the AIQ algorithm to realize automatic face coding for purchasing customers to protect customer privacy.

[0019] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0020] Before formally describing the present invention, the scheme of the present invention is first generally described for easy understanding.

[0021] Please refer to Figure 1 , Figure 1 It is a schematic diagram of the overall structure of the main control device of the present invention;

[0022] The present invention provides a smart vending cabinet main control device with an AI camera, comprising:

[0023] A main control box and a main control circuit board located in the main control box; the main control circuit board includes: dual MIPI cameras, RF coaxial connector, AI main control unit and power supply.

[0024] Figure 1 The dual MIPI camera includes: a first MIPI camera 1 and a second MIPI camera 2.

[0025] It should be noted that the first MIPI camera 1 and the second MIPI camera 2 can be retracted and extended, that is, Figure 1 The camera can be extended or retracted in the middle view position.

[0026] The main advantages of the MIPI camera in the present invention include fast transmission speed, large amount of data transmission, low power consumption, and good anti-interference performance. Compared with the network camera used in traditional vending machines, it has obvious advantages.

[0027] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the connection between the AI ​​main control unit and the MIPI camera.

[0028] It should be noted that the dual MIPI cameras communicate with the AI ​​main control unit via the MIPI bus; the AI ​​main control unit communicates with the cloud server via the RF coaxial connector;

[0029] As an embodiment, the AI ​​main control unit includes a main control MCU and a main control NPU.

[0030] The master MCU obtains the dual MIPI camera video data and transmits it to the master NPU for processing.

[0031] The main control NPU uses the AIQ algorithm to process the video data and transmits the processed data to the cloud server via the RF coaxial connector.

[0032] It should be noted that the power supply is used to power the dual MIPI cameras and the AI ​​main control unit.

[0033] It should be noted that the main control circuit board is fixedly placed in the main control box through a waterproof cover.

[0034] Still reference Figure 1 , Figure 1 The figure shows a waterproof cover plate 4 and a water outlet 6. The traditional vending machine main control device is not waterproof enough. In the present invention, the waterproof cover plate and the water outlet 6 are used to discharge the accumulated water in time, so as to protect the main control circuit board from working safely without causing water accumulation.

[0035] Since the main control circuit board is inside the main control box, its structure is not shown. Overall, the circuit board still uses a PCB board, on which corresponding components are arranged to meet the connection requirements of the MIPI camera, AI main control unit, and RF coaxial connector in the present invention.

[0036] Still reference Figure 1 , Figure 1 RF coaxial connector 5 is shown in FIG. It should be noted that in traditional vending machines, feeder connection is adopted. The feeder mainly refers to the cable used to transmit signals, which plays the role of transmitting signals in many fields, but is subject to the quality and model of the feeder; the quality and model of the feeder are the key factors that directly affect the reception effect and signal transmission quality, and the traditional vending machines are subject to various factors such as cost and technology update, resulting in unstable defects in 4G signal processing.

[0037] In the present invention, the RF coaxial connector is welded and fixed on the main control circuit board. The RF coaxial connection mainly involves the transmission of radio frequency signals, especially in the field of wireless communications. RF stands for radio frequency, which refers to any frequency in the electromagnetic spectrum and is related to the diffusion of radio waves. When radio frequency current is supplied to the antenna, an electromagnetic field is generated and then propagates in space. Therefore, the present invention adopts wireless 4G communication to solve the technical problems of unstable transmission and inconvenient connection of traditional feeder connection. At the same time, communication with the cloud server can be carried out through 4G.

[0038] It should be noted that the main control box is also provided with a mounting hole for fixed connection with the smart vending cabinet light box.

[0039] Still reference Figure 1 , Figure 1 The smart vending cabinet light box mounting hole 3 is shown in FIG.

[0040] The main control circuit board also includes an indicator light for indicating the working status of the main control circuit board. The traditional main control board structure cannot directly install the main control on the vending cabinet light box, resulting in cumbersome installation of the main control device. The present application installs the main control box on the light box through the smart vending cabinet light box installation hole 3, achieving quick installation.

[0041] The beneficial effects of the present invention are: it facilitates installation on the smart vending cabinet light box; it solves the problem of water ingress during rain that damages the AI ​​main control; it adopts a new RF coaxial connector to solve the problem of unstable 4G signals; it solves the problem of frame drop and unclear video acquisition, and also greatly reduces the cost; it adopts the AIQ algorithm to solve the impact of the external environment on the MIPI camera; it adopts the AIQ algorithm to realize automatic face coding for purchasing customers to protect customer privacy.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
