Description

Technical Field

[0001] The present invention relates to the technical field of network advertisement push, in particular to a display system using a mobile gateway. Background Art

[0002] Displaying advertisements on display terminals (such as electronic screens) is a common method of advertising push. Existing display terminals used for advertising push generally contain 4G / 5G cards and display control cards to connect to cloud servers. First, the backend uploads the advertising information to the cloud server, which then communicates with the display terminal's 4G / 5G card to display the advertising information on the display terminal. This method is relatively modular and simple to implement, making it widely used in various advertising fields.

[0003] However, there are three problems: 1. This method generally requires a 4G / 5G module and a 4G / 5G card to be set up on the display terminal, and the 4G / 5G card needs to pay traffic fees every year. Since advertising push generally requires a large number of display screens with 4G / 5G modules, the cost is obviously high.

[0004] 2. Furthermore, 4G / 5G card registration requires a complex qualification review process. Businesses or organizations must first contact a mobile communications operator or its authorized agent to explain their need for bulk SIM cards. Then, according to the operator's requirements, they must prepare the necessary registration documents, such as their business license, legal representative ID, and the ID of the person handling the transaction. For bulk SIM cards, a detailed list of user information, including name and ID number, may also be required. This means that each SIM card requires individual real-name authentication, making it inconvenient for bulk applications. Furthermore, international certification for 4G / 5G modules is relatively strict, primarily involving FCC certification and local testing. FCC certification is a certification for products such as radio, television, telecommunications, and satellite communications, ensuring compliance with US safety and electromagnetic compatibility standards. Certain countries or regions may require local testing of 4G / 5G modules to ensure compliance with local communications standards and safety requirements. For example, Argentina will require that, starting March 1, 2022, equipment supporting 2G, 3G, and 4G / 5G technologies (for cellular phones, modules, devices, etc.) must be fully tested by an accredited Argentine laboratory to ensure the performance and safety of the equipment.

[0005] 3. 4G / 5G network security faces challenges. It is easy to be hacked by fake base stations, which can lead to criminals posting bad information on display terminals. Moreover, 4G / 5G is a real-time updated network. If the network is disconnected, the display terminal will not be able to display advertisements, and its reliability needs to be improved. The main problems facing 4G / 5G network security include hacker attacks, the spread of malware, security threats on smart terminals, security threats in wired links and wireless networks, security vulnerabilities, user data leakage, and device security issues. Hackers may use 4G / 5G networks to leak personal information, steal accounts, and steal sensitive data. The spread of malware may cause user devices to be infected, endangering the information security of individuals and enterprises. As the closeness between smart terminals and users of 4G / 5G systems deepens, the number of malicious programs that can be executed on terminals increases, making it easy to have security risks such as vulnerabilities in mobile terminal operating systems, virus attacks, and lax protection of communication interfaces. Security threats in wired links and wireless networks include fraud under the guise of operators, hackers stealing user information through technical means, and disguising themselves as legal entities. Illegal users enter the network, and the fault tolerance of 4G / 5G networks needs to be improved. There are various security vulnerabilities in the design of software and hardware of 4G / 5G networks, such as the key and algorithm security issues in the encryption and decryption process of wireless transmission of uplink and downlink data, as well as buffer overflows, improper parameter configuration, unauthorized access and other security vulnerabilities. Due to the real-time and high-speed nature of 4G / 5G networks, when users transmit data through 4G / 5G networks, the security risks increase accordingly. Devices in 4G / 5G communication networks may have various security vulnerabilities, allowing hackers to invade devices and obtain user information. Summary of the Invention

[0006] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a low-cost and highly reliable display system using a mobile gateway.

[0007] According to an embodiment of the present invention, a display system using a mobile gateway includes a cloud server that communicates with a background terminal, and the background terminal can upload information data to the cloud server; a smart mobile terminal that can be carried by a user and can communicate with the cloud server, and a gateway APP is downloaded on the smart mobile terminal to receive the information data; a display terminal, and the display terminal and the smart mobile terminal are respectively provided with a Bluetooth module, and the gateway APP can communicate with the display terminal by Bluetooth to send the information data to the display terminal, and the gateway APP does not have the function of changing the content of the information data, so that the user carrying the smart mobile terminal cannot change the content of the information data.

[0008] The display system using a mobile gateway according to an embodiment of the present invention has at least the following beneficial effects: a backend terminal sends information data to a smart mobile terminal through a cloud server, and the smart mobile terminal receives the information data through a gateway APP and sends the information data to the display terminal via Bluetooth. That is, the user's smart mobile terminal (such as a smartphone, tablet, etc.) is used as a gateway to transmit information data. The smart mobile terminal moves with the user. When it moves within the Bluetooth communication range of the display terminal, information data can be transmitted. When there are multiple display terminals and multiple users carrying the smart mobile terminals, the multiple display terminals can display information data by communicating with any smart mobile terminal through Bluetooth, resulting in high information transmission efficiency and convenient advertising push. In addition, compared with traditional systems that push advertisements through 4G / 5G networks, this system reduces 4G / 5G modules and 4G / 5G cards, eliminating the need for traffic fees and the cumbersome 4G / 5G card registration process. In particular, when applied overseas, there is no need for 4G / 5G module certification and is not subject to overseas restrictions on 4G / 5G. When applied to multiple display terminals, a large number of 4G / 5G modules can be saved, significantly reducing costs. When the information data is successfully transmitted, the information data is stored in the memory of the display terminal. The smart mobile terminal can close the gateway APP or turn off the network without affecting the normal operation of the display terminal. In addition, the security level of general smart mobile terminals (mobile phones) is level 3. The gateway APP is not easy to break into and has a high security level. In addition, the gateway APP does not have the function of changing the information content, so users cannot change the content of the information data and have high reliability.

[0018] Reference Figures 1 to 4The present invention provides a display system using a mobile gateway, including a cloud server, an intelligent mobile terminal and a display terminal. The cloud server communicates with the background terminal, and the background terminal can upload information data to the cloud server; the intelligent mobile terminal can be carried by the user and can communicate with the cloud server, and a gateway APP is downloaded on the intelligent mobile terminal to receive information data; a Bluetooth module is respectively provided on the display terminal and the intelligent mobile terminal, and the gateway APP can communicate with the display terminal by Bluetooth to send information data to the display terminal, and the gateway APP does not have the function of changing the content of the information data, so that the user carrying the intelligent mobile terminal cannot change the content of the information data, and the display terminal has a data storage function, and the latter information data can refresh the previous information data, so that the display terminal displays and saves the latest information data. The backend terminal sends information data (including text data, audio data and video data) to the smart mobile terminal through the cloud server. The smart mobile terminal receives the information data through the gateway APP and sends the information data to the display terminal via Bluetooth. That is, the user's smart mobile terminal (such as a smartphone, tablet, etc.) is used as a gateway to transmit information data. The smart mobile terminal moves with the user. When it moves within the Bluetooth communication range of the display terminal, the information data can be transmitted. When there are multiple display terminals and multiple users carrying the smart mobile terminal, the multiple display terminals can display the information data by communicating with any smart mobile terminal through Bluetooth. The information transmission efficiency is high and it is convenient for advertising push. Compared with the traditional system for advertising push through the 4G / 5G network, this system reduces the 4G / 5G module and 4G / 5G card, and there is no need to pay traffic fees or go through the cumbersome 4G / 5G card registration process. Especially when applied abroad, there is no need for 4G / 5G module certification and is not subject to foreign restrictions on 4G / 5G. When applied to multiple display terminals, a large number of 4G / 5G modules can be saved, and the cost is significantly reduced. When the information data is successfully transmitted, the information data is stored in the memory of the display terminal. The smart mobile terminal can close the gateway APP or turn off the network without affecting the normal operation of the display terminal. In addition, the security level of general smart mobile terminals (mobile phones) is level 3. The gateway APP is not easy to break into and has a high security level. In addition, the gateway APP does not have the function of changing the information content, so users cannot change the content of the information data and have high reliability.

[0019] like Figure 2In some embodiments, there are multiple zones, each containing at least one display terminal. There are multiple pieces of information data, each corresponding one-to-one to each zone. The backend terminal is capable of monitoring the location of the smart mobile terminal (existing smartphones, tablets, etc. generally have positioning functions, and the backend can monitor the zone in which the smart mobile terminal is located through GPS positioning). Furthermore, the gateway app on each smart mobile terminal has a corresponding user ID. The backend terminal can group multiple user IDs according to their zones and transmit the corresponding information data to the smart mobile terminals in the corresponding zones via the cloud server. For example, when a user is in zone A, the backend terminal transmits information data A to the user's phone via the cloud server. The gateway app on the phone then sends information data A to display terminal A in zone A, which displays information data A. When the user is detected moving into zone B, the backend terminal transmits information data B to the user's phone via the cloud server. The gateway app on the phone then sends information data B to display terminal B in zone B, which displays information data B. This enables grouped display of information data to meet market demand.

[0020] In some embodiments, there are multiple smart mobile terminals, and any smart mobile terminal can perform Bluetooth communication with a display terminal within the Bluetooth communication range to display corresponding information data, thereby realizing group control and improving the transmission efficiency of information data.

[0021] like Figure 4 In some embodiments, there are multiple smart mobile terminals and multiple display terminals. Any smart mobile terminal follows the user's movement to communicate with any display terminal within the Bluetooth communication range to display corresponding information data, further improving the transmission efficiency of information data and increasing the possibility of the display terminal displaying the latest data information.

[0022] In some embodiments, there are multiple smart mobile terminals and multiple display terminals, and the display terminals are movable. Any smart mobile terminal follows the user's movement to perform Bluetooth communication with any display terminal within the Bluetooth communication distance to display corresponding information data. Since both the display terminal and the smart mobile terminal are movable and there are multiple of each, the probability of reducing the communication distance between the two is increased, thereby further improving the transmission efficiency of information data and the possibility of the display terminal displaying the latest data information.

[0023] In some embodiments, multiple smart mobile terminals are associated with multiple display terminals. The smart mobile terminals follow the user's movements and communicate with the corresponding display terminals via Bluetooth to display corresponding information data. In other words, the smart mobile terminals and display terminals are bound to each other in a one-to-one manner, facilitating group management and meeting market demand.

[0024] In a specific application, for example, a food delivery app consists of a cloud server, the delivery driver's phone, and a delivery box with a display terminal. The backend terminal uploads information data to the cloud server. The delivery driver simply connects his phone to the internet, downloads and registers the gateway app on his phone, and the cloud server transmits the information data to the gateway app on his phone. The gateway app then transmits the information data via Bluetooth to the display terminal on the delivery box for display. Even if the phone is turned off or the internet is disconnected, the information displayed on the display terminal is not affected. With the large number of delivery drivers currently on the market, advertising through the delivery driver's phone and the electronic screen of the delivery box is efficient, low-cost, and highly reliable.

[0025] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above preferred embodiments can be freely combined and superimposed.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
