Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display screen operation and maintenance control device, system and display system. Background Art

[0002] In the current commercial display industry (hereinafter referred to as the commercial display industry), in order to facilitate the operation and maintenance management of commercial display devices such as commercial display screens, an operation and maintenance management solution based on the Android system is proposed. The solution includes display operation and maintenance control devices such as Android boards, Xinfa APP (an application for pushing and playing videos, pictures and other content on commercial display devices), and a cloud platform backend management system that is compatible with it. This combination allows users to log in to the cloud platform through a mobile phone or computer to remotely control and manage the content push and playback on the board. However, although the existing solutions meet the basic operation and maintenance needs to a certain extent, they still have some significant shortcomings. First, the existing solutions usually can only provide basic content push and playback functions, lacking more flexible and intelligent control mechanisms, such as pay-on-demand advertising playback control; second, the operation and maintenance functions of the existing solutions rely heavily on the overall stability of the system. For Android-based boards, if the system fails or restores factory settings, important data stored on the board may be lost. This situation not only affects the normal operation and maintenance of the device, but may also cause the user's purchased services to be unable to continue to be used, thereby adversely affecting the user's experience. In addition, existing solutions also have deficiencies in the arrears management function. Although some solutions can restrict content playback in the case of arrears, these restrictions are usually simple and lack multi-level management strategies. For example, when the board is in arrears, it can usually only simply stop playing content, but cannot further implement operations such as timed shutdown and screen standby. This simple arrears management method cannot flexibly respond to different user needs, reducing user experience and service quality. Summary of the invention

[0022] Embodiment 1

[0023] See also Figure 1 An embodiment of the present invention provides a display screen operation and maintenance control device 1, which is connected to a display screen 2 and a cloud platform 3 respectively. The display screen 2 here can be an LCD display screen, an LED display screen, an OLED display screen, a projection display screen, a plasma display screen, a naked-eye 3D display screen, etc. These display screens can be used as commercial display screens (commercial display screens) for commercial advertising and information display indoors or outdoors.

[0024] Specifically, the display screen operation and maintenance control device 1 at least includes a main control unit 11, a micro control unit 12, a network communication unit 13 and a signaling APP unit 14, wherein the main control unit 11 is used to manage and control the operation of the display screen operation and maintenance control device 1, the network communication unit 13 is used to communicate with the cloud platform 3, the micro control unit 12 is used to store preset broadcast control status information and to drive the display screen operation and maintenance control device to perform screen standby or timed power on / off management on the display screen 2 according to the preset management information from the signaling APP unit 14, the signaling APP unit 14 is used to receive preset graphic information from the cloud platform 3 through the network communication unit 13, and to modify the preset broadcast control status information according to the transaction information issued by the cloud platform 3 and then write it into the micro control unit 12, the signaling APP unit 14 is also used to read the preset broadcast control status information from the micro control unit 12 and generate the preset management information based on it or drive the display screen 2 to display the preset graphic information.

[0025] In one embodiment, the main control unit is a SOC chip integrated with the Android system, the main operating system of the entire display screen operation and maintenance control device is the Android system, the microcontroller unit is a 16-bit, 32-bit or 64-bit MCU, the main control unit communicates with the microcontroller unit through the I2C protocol, the network communication unit is any one or more of an Ethernet module, a WIFI module or a 4G / 5G communication module, and can support Ethernet, WIFI or 4G, 5G network communication, and the network communication unit communicates with the main control unit through the PHY interface, PCIe interface, SDIO interface, etc. integrated in the display screen operation and maintenance control device. The Xinfa APP unit is an application built into the main control unit, which can communicate or interact with the cloud platform through the network communication unit, receive preset graphic information and other data issued from the cloud platform, and drive the display screen motion control module to control the display screen to display preset graphic information according to the playback rules set by the user, such as playing videos, pictures, text, etc. The preset graphic information includes any one or more combinations of videos, pictures, and texts.

[0026] In one embodiment, when the display screen operation and maintenance control device is powered on and started, the main control unit controls the micro control unit to perform initialization operations and starts the signal sending APP unit at the same time. The signal sending APP unit reads the data stored in the micro control unit and performs data analysis to obtain preset broadcast control status information.

[0027] Preferably, the preset broadcast control status information includes any one of the first broadcast control status information, the second broadcast control status information and the third broadcast control status information, wherein the first broadcast control status information indicates that the display screen operation and maintenance control device has not activated the broadcast control function, the second broadcast control status information indicates that the display screen operation and maintenance control device has activated the broadcast control function but is in arrears, and the third broadcast control status information indicates that the display screen operation and maintenance control device has activated the broadcast control function and is in a normal state; wherein the broadcast control function allows the user to display the preset graphic information on the display screen according to the method or playback rules set by the user, for example, the user can choose which specific advertising content to play in which time periods, and in which playback methods (such as loop playback, intermittent playback), etc. The preset broadcast control status information is stored in the micro control unit. The preset broadcast control status information is stored in the micro control unit (such as MCU) to realize power-off protection of data. Micro control units such as MCU usually have a power-off saving function. Even if the main operating system (such as Android system) is powered off or restarted, the broadcast control status information stored therein will not be lost. After the system is restored or restarted, the data can be read from the micro control unit, so that the device can continue to operate according to the previous set state, avoiding service interruption caused by data loss. In addition, during the system update or maintenance process, the preset broadcast control status information in the micro control unit will not be affected. When the system is upgraded or fault repaired, there is no need to worry about the broadcast control status information being cleared or tampered with, thereby simplifying the maintenance of the system and avoiding the trouble of users needing to reconfigure the broadcast control status. Further, the preset broadcast control status information is stored in the micro control unit, so that the information can be managed independently of the main operating system (such as Android system). When the main system fails or needs to be reset, the micro control unit can still maintain basic control of the display screen to ensure the normal operation of the basic functions of the system. For example, when the main system fails, the microcontroller unit can control the display screen to enter a safe mode or turn off the display screen according to the stored preset broadcast control status information to avoid accidental display of content.

[0028] When the preset broadcast control status information obtained by the signal transmission APP unit from the micro control unit is the first broadcast control status information, that is, the display screen operation and maintenance control device has not activated the broadcast control function and cannot display the preset graphic information, the signal transmission APP unit will send the preset prompt information according to the first broadcast control status information. The preset prompt information here can be displayed in the form of a page, a window or a dialog box, and can include any one or more of text, images, QR codes, web links and other information. The preset prompt information is used to prompt the user to register or log in through the cloud platform to conduct a transaction to activate the broadcast control function. The user can register or log in through the mobile phone APP or PC web page according to the preset prompt information. Register or log in to the cloud platform, and then perform transaction operations such as paying for the playback time. When the transaction is successful, the cloud platform sends the transaction information to the Xinfa APP unit. After receiving the transaction information from the cloud platform, the Xinfa APP unit modifies the preset broadcast control status information from the first broadcast control status information to the third broadcast control status information, that is, the broadcast control function has been activated and is in a normal state. At this time, the user can send the preset graphic information to be played to the cloud platform through a terminal such as a mobile phone or PC, and the cloud platform will send it to the Xinfa APP unit. After receiving the preset graphic information, the Xinfa APP unit will drive the display motion control module to control the display to display the preset graphic information.

[0029] When the preset broadcast control status information obtained by the signal transmission APP unit from the micro control unit is the second broadcast control status information, that is, the display screen operation and maintenance control device has activated the broadcast control function but is in arrears, the signal transmission APP will read data from the micro control unit at preset intervals or periodically, parse and obtain the preset broadcast control status information, monitor and record the duration when the preset broadcast control status information is the second broadcast control status information.

[0030] When the duration is less than or equal to the first preset time, the information sending APP unit drives the display screen to display preset prompt information, which can be displayed in the form of a page, window or dialog box, and can include any one or more of text, image, QR code, web link and other information, prompting the user to log in to the existing account through the cloud platform and perform renewal transactions; when the duration is greater than the first preset time, the information sending APP can be driven to generate and send preset management information, where the preset management information includes preset standby information and preset timed power on / off information. When the duration is greater than the first time but less than or equal to the second preset time, the information sending APP unit sends the preset standby information to the micro control unit, and the micro control unit drives the display screen operation and maintenance control device to enter the standby state with the preset standby information, and at the same time performs screen off processing on the display screen; when the duration is greater than the second preset time, the information sending APP unit sends the preset timed power on / off information to the micro control unit, and the micro control unit will drive the display screen operation and maintenance control device to timed power on / off according to the preset timed power on / off information, and also turns off the display screen when it is turned on to save energy.

[0031] In the embodiment of the present invention, the microcontroller unit implements basic control operations on the display screen operation and maintenance control device and the display screen, such as standby and timed power on / off functions, after receiving the preset management information from the Xinfa APP unit. When in arrears, the microcontroller unit will automatically control the display screen operation and maintenance control device and the display screen to enter low power consumption mode or timed power on / off according to the set time threshold to save energy and remind the user to renew. When the user completes the transaction through the cloud platform, the Xinfa APP unit will update the broadcast control status stored in the microcontroller unit from the arrears status to the normal status, ensuring that the display screen can resume normal display and operation in a timely manner.

[0032] Exemplarily, the first preset time is 7 days, and the second preset time is 15 days. When the Xinfa APP unit reads that the preset broadcast control status information stored in the micro control unit is the second broadcast control status information, it will read the data in the micro control unit periodically or at every preset time interval (which can be set according to actual conditions, such as every 1 hour, 2 hours or 5 hours, etc.), monitor and record the duration of the second broadcast control status (that is, although it is activated but in arrears). If the arrears time is less than or equal to 7 days, then the Xinfa APP unit will issue a preset prompt message, which can be displayed on the display screen or on a mobile phone, tablet computer or PC connected to the cloud platform to remind the user to renew to maintain the broadcast control function. If the user successfully renews through the cloud platform during this period, the cloud platform will send transaction information to the Xinfa APP unit, and the Xinfa APP unit will modify the preset broadcast control status information from the second broadcast control status information to the third broadcast control status information, and drive the display screen operation and maintenance control device to drive the display screen to normally display the preset graphic information.

[0033] If the arrears time is greater than 7 days but less than 15 days, the screen will be turned off and put into standby mode. At this time, the Xinfa APP will send a preset standby message to the microcontroller unit, and the microcontroller unit will drive the display screen operation and maintenance control device to turn off the screen. At the same time, the display screen operation and maintenance control device will also enter standby mode, thereby saving energy consumption. At the same time, after the user's renewal operation is successful, the display screen operation and maintenance control device and the display screen can quickly enter the working state. If the user successfully renews through the cloud platform during this period, the cloud platform will send transaction information to the Xinfa APP unit, and the Xinfa APP unit will modify the preset broadcast control status information from the second broadcast control status information to the third broadcast control status information. The microcontroller unit will switch the display screen operation and maintenance control device from standby mode to normal working mode to drive the display screen to normally display the preset graphic information.

[0034] If the arrears time is greater than 15 days, the Xinfa APP unit sends the preset timed power on / off information to the microcontroller unit, and the microcontroller unit drives the display screen operation and maintenance control device to timed power on / off, for example, shut down from 18:00 to 6:00 in the evening, and turn on and standby at other times, but at the same time control the display screen to be off. When the user successfully renews through the cloud platform, the cloud platform will send transaction information to the Xinfa APP unit during the power-on period, and the Xinfa APP unit will modify the preset broadcast control status information from the second broadcast control status information to the third broadcast control status information, and clear the preset timed power on / off information, and the microcontroller unit will switch the display screen operation and maintenance control device from standby mode to normal working mode to drive the display screen to normally display the preset graphic information.

[0035] When the preset broadcast control status information obtained by the Xinfa APP unit from the microcontroller unit is the third broadcast control status information, that is, the display screen operation and maintenance control device has activated the broadcast control function and is in a normal state, the Xinfa APP unit does not need to perform any operation, and the display screen operation and maintenance control device normally drives the display screen to display the preset graphic information (the preset graphic information has been obtained from the cloud platform when the broadcast control function is activated). When the preset graphic information needs to be updated, the user can log in to the cloud platform through a mobile phone, tablet phone or PC and transmit the updated preset graphic information to the cloud platform. The cloud platform sends the updated preset graphic information to the Xinfa APP unit, and the Xinfa APP unit drives the display screen to display the updated preset graphic information through the display screen operation and maintenance control device.

[0036] In summary, the display screen operation and maintenance control device provided by the embodiment of the present invention realizes data persistence and power-off protection functions by adopting a micro control unit (MCU) to store and manage preset broadcast control status information. Different from the data storage method of the traditional Android board card that relies on the operating system, the micro control unit can independently save important data including the first broadcast control status information (broadcast control function not enabled), the second broadcast control status information (enabled but in arrears) and the third broadcast control status information (enabled and normal). Even if the system fails or restores the factory settings, the broadcast control status information will not be lost, which improves the stability of the system and ensures that the device can continue to operate according to the set state after the system is restored, avoiding operation and maintenance interruptions caused by data loss, thereby improving the user experience. Secondly, the display screen operation and maintenance control device introduces a more flexible and intelligent control mechanism in operation and maintenance management. For example, users can set the paid playback rules of advertisements through the letter-sending APP unit according to their needs, and send these rules to the micro control unit for persistent storage. When the user completes the payment transaction, the micro control unit will immediately update the broadcast control status and drive the display screen to play content according to the new rules. This pay-as-you-go intelligent control mechanism not only meets the diverse needs of users, but also provides greater flexibility and accuracy for advertising, significantly improving service quality and user satisfaction.

[0037] In terms of arrears management, the display screen operation and maintenance control device of the embodiment of the present invention has the advantage of a multi-level management strategy. Different from the traditional arrears management method of simply stopping playback, this module can gradually take different response measures according to the length of the arrears time. For example, when the arrears time is less than the first preset time, the system will first prompt the user to renew through the message sending APP unit; when the arrears time exceeds the first preset time but is less than the second preset time, the system will automatically switch the display screen to standby or screen-off mode to reduce energy consumption; if the arrears time exceeds the second preset time, the timed power on and off strategy will be executed to further restrict usage by shutting down the device. This multi-level management strategy can not only flexibly respond to the needs of different users, but also effectively improve the utilization efficiency of resources, ensure the continuity of operation and maintenance and the normal operation of the system.

[0038] In summary, the display screen operation and maintenance control device of the embodiment of the present invention provides an intelligent and automated display screen operation and maintenance solution through the coordinated work of the main control unit, the micro control unit, the network communication unit and the letter sending APP unit. Among them, the main control unit is responsible for overall management and operation control to ensure the coordinated operation of various parts of the system; the network communication unit ensures the data exchange function with the cloud platform; by adopting the micro control unit to store and manage the preset broadcast control status information, the data persistence and power-off protection function can be realized, the stability of the system is improved, and it is also ensured that the device can continue to operate according to the set state after the system is restored, avoiding the operation and maintenance interruption caused by data loss, thereby improving the user experience. In addition, the micro control unit will also drive the display screen operation and maintenance control device to standby or timed switch according to the preset management information from the letter sending APP unit to reduce energy consumption; the letter sending APP unit is an interface for interacting with the cloud platform, responsible for receiving and pushing content, data updating, and implementing the execution and intelligent control of playback rules based on the broadcast control status and the micro control unit, which provides higher flexibility and accuracy for the delivery of graphic information such as advertisements, and significantly improves the quality of service and user satisfaction.
