[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] In the description of the present invention, the terms "comprises", "has" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may also include other steps or units that are not explicitly listed but are inherent to these processes, methods, products or apparatuses, or steps or units added based on further optimization schemes conceived by the present invention.

[0034] At present, there are two major drawbacks in the operation and maintenance control of smart vending machines. First, technicians can perform real-time control in front of the machine through a USB cable, but this operation requires opening the device and exposing its internal structure, which not only poses a safety hazard, but also affects the normal operation of the smart vending machine during operation and affects the machine's sales. Secondly, in the wide-area environment of the Internet of Things, it is difficult for technicians to perform real-time control of smart vending machines, such as executing key tasks such as adb commands, multimedia operations, and desktop control, which limits the remote maintenance and management capabilities of the equipment. Therefore, a safe, convenient, and real-time contactless control method is urgently needed for the control of smart vending machine systems.

[0035] The pain points of existing technologies include:

[0036] ① Risk of USB cable control in front of the machine: Currently, technicians can control the machine in real time through a USB cable, but this method requires opening the device, exposing the internal structure, which poses a safety hazard. At the same time, it will interfere with the normal operation of the smart vending machine during operation and affect sales.

[0037] ② Limitations of wide-area control of the Internet of Things: In the wide-area environment of the Internet of Things, it is difficult for technicians to perform key tasks such as adb commands, multimedia operations, and desktop control on smart vending machines, which limits the remote maintenance and management capabilities of the equipment.

[0038] Introduction to the use of smart vending machine virtual LAN security control:

[0039] When the technician arrives at the smart vending machine, he inputs the machine number through the remote control system and issues a command to start the hotspot. After receiving the command, the smart vending machine turns on the camera and automatically performs facial recognition verification on the operator. If the verification passes, the hotspot is turned on. The technician enters the 8-digit random password generated by the system on the control terminal (PC or mobile phone) to establish a virtual LAN with the machine.

[0040] The smart vending machine system is equipped with scrcpy to transfer desktop images, start the dlna sharing service, run the specified server software, open random ports 5555 to 9999, and publish the control end web page;

[0041] The technician can enter http: / / 127.0.0.1:open port / in the browser of the control terminal (PC or mobile phone) to perform the virtual desktop and command operations of the smart vending machine;

[0042] The hotspot will be closed within the preset time, and the corresponding sharing service will be uninstalled and the data cache will be cleared to ensure system security. To continue control, you need to repeat steps ① to ③;

[0043] The shortcomings of existing methods include:

[0044] Controlling the transmission of large amounts of data (multimedia operations) will affect the current use of smart vending machines, manifested as software freezes and network delays;

[0045] Specific objectives of this application include:

[0046] Realize contactless operation and maintenance in front of smart vending machines to ensure that the normal sales of the machines are not affected.

[0047] Realize the safe opening of the local hotspot of the smart vending machine to ensure the convenience and safety of the control process.

[0048] Realize the shared service of customized web page control for smart vending machines, and provide remote real-time desktop viewing and command control functions.

[0049] Implement an automated safety mechanism for smart vending machines to ensure that hotspots are automatically shut down and data caches are cleared within a preset time, improving system security.

[0050] In order to achieve contactless operation and maintenance in front of the machine and avoid affecting the normal sales of smart vending machines, the entire operation process sets up virtual LAN ports 5555 to 9999, and avoids the existing smart vending machine business ports. With the help of machine remote control instructions and intelligent verification mechanism, there is no need for operation and maintenance personnel to directly contact the internal hardware of the equipment. The operation and maintenance personnel control the system remotely through the virtual LAN and issue instructions to the smart vending machine in a non-physical contact manner. The smart vending machine automatically completes the corresponding operation based on the received instructions, realizing the parallel operation and maintenance process and the normal sales process of the machine.

[0051] Please refer to Figure 1 , which shows a flow chart of a method for controlling the security of a virtual local area network of an intelligent vending machine provided by an embodiment of the present application. The method may include the following steps:

[0052] S1, the operator sends a hotspot-enabling command to the smart vending machine through the remote control system. After receiving the command, the smart vending machine verifies the operator's identity. After the verification is passed, the local hotspot is enabled and a virtual local area network is established with the technician's control terminal.

[0053] This step specifically includes:

[0054] The operator inputs the unique number of the smart vending machine through the remote control system (such as a cloud management platform or a dedicated APP) and sends a command to the target smart vending machine to turn on the hotspot. The remote control system verifies the operator's authority to ensure that only authorized personnel can initiate the command.

[0055] The smart vending machine receives the hotspot-enabling command sent by the remote control system through a built-in communication module (such as Wi-Fi, 4G / 5G module). The smart vending machine parses the received command to confirm the legitimacy and integrity of the command.

[0056] After receiving the hotspot-enabling command, the smart vending machine starts the built-in camera to perform facial recognition verification on the operator. Facial recognition technology verifies the identity of the operator through image recognition algorithms based on the pre-stored facial data of authorized personnel. Figure 2 A schematic diagram of the smart vending machine turning on the camera after receiving instructions is given.

[0057] If the verification passes, the smart vending machine proceeds to the next step; if the verification fails, it refuses to turn on the hotspot and sounds an alarm.

[0058] After the verification is passed, the smart vending machine turns on the local hotspot and randomly generates an encrypted 8-digit password, which is generated by an encryption algorithm to ensure unpredictability. The technician enters the password on the control terminal (such as a PC or mobile phone) to establish a virtual LAN connection with the smart vending machine. The port range of the virtual LAN is 5555 to 9999, avoiding the ports used by the normal business of the smart vending machine to ensure that the operation and maintenance operations do not affect the normal sales of the machine.

[0059] S2, the smart vending machine starts the desktop mirroring transmission service and transmits the desktop image to the control end in real time; at the same time, it starts the sharing service, runs the server software and opens the port to publish the control end web page.

[0060] This step specifically includes:

[0061] The smart vending machine system starts the desktop image transmission service, and transmits the desktop screen of the smart vending machine to the control end in real time through built-in open source software (such as scrcpy) or custom software. This service can transmit the screen content of the smart vending machine to the control end in the form of a video stream, and technicians can view the operation interface of the smart vending machine in real time on the control end.

[0062] The smart vending machine starts the sharing service (such as DLNA or other custom protocols) and runs the specified server software to share data and commands between the smart vending machine and the control terminal. The system randomly selects a port in the range of 5555 to 9999 to open, which is used to establish a communication connection between the control terminal and the smart vending machine.

[0063] Based on the above settings, the smart vending machine publishes a control-end web page, which embeds a real-time desktop mirror image and a virtual command window. The technician can access the web page through the browser of the control end to remotely operate and monitor the smart vending machine. The design of the control-end web page ensures the convenience and intuitiveness of operation, and the technician can manage the smart vending machine just like operating a local device.

[0064] S3, the technician enters the corresponding IP address and open port in the browser of the control end, accesses the control end web page, and performs real-time desktop viewing and command operations of the smart vending machine.

[0065] In this step:

[0066] The technician enters the IP address of the smart vending machine and an open random port in the browser of the control terminal (such as a PC or mobile phone). The browser connects to the control terminal web page published by the smart vending machine through the address. The technician accesses the desktop image and control functions of the smart vending machine through the web interface.

[0067] The control end webpage embeds the real-time desktop image of the smart vending machine, through which technicians can view the operation interface and status of the smart vending machine in real time. The desktop image transmission service ensures the real-time and smoothness of the image, and technicians can clearly see the current operation status of the smart vending machine.

[0068] The control end webpage provides a virtual command window, through which technicians can input commands or operating instructions to remotely control the smart vending machine. After receiving the instructions sent by the control end, the smart vending machine automatically performs the corresponding operations, such as software updates, troubleshooting, and product replenishment.

[0069] Furthermore, the method also includes:

[0070] After the smart vending machine turns on the hotspot and successfully establishes a virtual LAN, it automatically sets a preset time. When the preset time arrives, it automatically turns off the hotspot, uninstalls the sharing service, and clears the data cache to ensure system security.

[0071] like Figure 3 A method implementation framework diagram is given. In an optional embodiment of the present application, the present application implements the following contents respectively:

[0072] Realize the safe opening of local hotspots of smart vending machines:

[0073] Instruction issuance and identity verification: After the technician arrives at the location of the smart vending machine, he logs into the remote control system, enters the unique number of the smart vending machine, and then issues an instruction to open the local hotspot. After receiving this instruction, the smart vending machine immediately starts the camera and automatically verifies the operator's face recognition. This process uses advanced face recognition technology to ensure that only authorized technicians can continue subsequent operations, ensuring the security of hotspot activation from the personnel identity level.

[0074] Hotspot activation and password generation: When the operator passes the facial recognition verification, the smart vending machine activates the local hotspot and randomly generates an 8-digit password. The random password is generated using an encryption algorithm to ensure the unpredictability of the password.

[0075] Virtual LAN establishment: The technician enters the 8-digit random password on the control terminal (PC or mobile phone) to establish a virtual LAN with the smart vending machine. This virtual LAN establishment method based on password verification further strengthens the security of the connection. Only the control terminal that knows the random password can successfully access, preventing illegal devices from accessing and causing security threats.

[0076] Implementing the shared service of custom web page control for smart vending machines:

[0077] Desktop image transmission: The smart vending machine system is installed with the open source scrcpy software, which has a powerful desktop image transmission function. Through this software, the smart vending machine can transmit its own desktop image to the control end in real time, so that the technicians can view the desktop content of the smart vending machine at the control end just like operating a local device.

[0078] Sharing service startup and port opening: At the same time, the smart vending machine starts the system's DLNA sharing service and runs the specified server software. During this process, the system will randomly open a port from the port range of 5555 to 9999. This random port selection method increases the security of the system and reduces the risk of malicious scanning and attacks.

[0079] Control terminal web page publishing and operation: Based on the above settings, the smart vending machine publishes the control terminal web page. This web page is carefully designed and embedded with a real-time scrcpy desktop mirror image and a virtual command window. The technician can access the web page by entering the corresponding IP address and an open random port in the browser of the control terminal (PC or mobile phone), thereby performing real-time desktop viewing of the smart vending machine and various command control operations, realizing convenient and efficient remote control.

[0080] Realize the automated safety mechanism of smart vending machines:

[0081] Preset time setting: After the smart vending machine turns on the hotspot and successfully establishes a virtual LAN, the system automatically sets a preset time, such as half an hour. This preset time can be flexibly adjusted according to actual operation and maintenance needs, aiming to provide technicians with sufficient operation time while effectively controlling potential security risks.

[0082] Automatic cleaning and security assurance: When the preset time arrives, the smart vending machine will automatically perform a series of security operations, including shutting down the hotspot to prevent unauthorized devices from accessing it at a later time; uninstalling the corresponding shared service to avoid unnecessary continued operation of the shared service and causing security risks; clearing the data cache to prevent the leakage of sensitive information that may be contained in the cached data. If the technician needs to continue to control the smart vending machine, he needs to repeat the above steps of opening the hotspot, identity verification, establishing a virtual LAN, and accessing the control end web page to ensure that each control process is in a safe and controllable state.

[0083] Please refer to Figure 4 , which shows a block diagram of a smart vending machine virtual local area network security control system provided by an embodiment of the present application. Figure 4 As shown, the system may include:

[0084] The verification networking module is used by the operator to send a hotspot-enabling command to the smart vending machine through the remote control system. After receiving the command, the smart vending machine verifies the identity of the operator. After the verification is passed, the local hotspot is enabled and a virtual local area network is established with the technician's control terminal.

[0085] The port sharing module is used for the smart vending machine to start the desktop mirror transmission service and transmit the desktop image to the control end in real time; at the same time, the sharing service is started, the server software is run, and the port is opened to publish the control end web page;

[0086] The control operation module is used by technicians to enter the corresponding IP address and open port in the control terminal browser to access the control terminal web page and perform real-time desktop viewing and command operations of the smart vending machine.
