Description

Technical Field

[0001] This application relates to the technical field of LED large screen dual systems, and in particular to a system, method and medium for implementing an LED large screen dual system. Background Art

[0002] With the rapid development of information technology, as an important information dissemination tool, LED display screens are widely used in various public places and commercial activities. However, traditional LED screens have problems such as a single operating system and poor ecological compatibility, making it difficult to meet the modern information dissemination requirements for efficiency and intelligence. In addition, LED large screens also face problems of poor system operation reliability and high costs. Therefore, it is of great significance to study the multi-system redundancy technology for LED large screens, and relevant enterprises should continuously strengthen technological innovation to improve the intelligent level of LED large screen devices.

[0003] Currently, dual-system LED large screen products on the market usually come with two independent system management units, and the two modules achieve data sharing and synchronization through the OPS interface. Existing solutions basically adopt the master-slave technology, and both system management units need to be online simultaneously during system switching; the operating systems mainly involve the Android system and the Windows system, and there are relatively few products for systems such as LINUX, domestic Kirin, and Tongxin.

[0004] Although existing solutions have improved system flexibility and software compatibility, they also have some disadvantages. First, the existing technology requires the integration of an OPS computer, and both units need to be online simultaneously during system switching, which greatly increases the hardware cost and energy consumption of the product; second, using the Windows system is more vulnerable to attacks such as Trojans and viruses, resulting in system crashes, data loss, and even affecting the normal operation of another system. Finally, using the existing solution increases the startup time and maintenance cost of the device. Summary of the Invention

[0005] Aiming at the above deficiencies of the existing technology, this application provides a system, method and medium for implementing an LED large screen dual system to solve the problems that the existing technology requires the integration of an OPS computer, and both units need to be online simultaneously during system switching, which greatly increases the hardware cost and energy consumption of the product; second, using the Windows system is more vulnerable to attacks such as Trojans and viruses, resulting in system crashes, data loss, and even affecting the normal operation of another system; finally, using the existing solution increases the startup time and maintenance cost of the device.

[0006] In a first aspect, this application provides a system for implementing an LED large screen dual system, the system includes:

[0008] The online learning method provided by the embodiments of the present application. In the existing solution, an OPS computer needs to be integrated, and when switching systems, the two systems need to be online simultaneously, which increases the hardware cost (such as additional computer devices, storage devices, etc.) and energy consumption (such as power consumption).
