Description

Technical Field

[0001] The present application relates to the technical field of large-scale LED screen dual systems, and in particular to a system, method and medium for realizing a large-scale LED screen dual system. Background Art

[0002] With the rapid development of information technology, LED display screens, as an important information dissemination tool, 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. It is difficult to meet the needs of modern information dissemination for efficiency and intelligence. In addition, LED large screens also face problems such as poor system operation reliability and high cost. Therefore, it is of great significance to study the multi-system redundancy technology of LED large screens. Relevant companies should continuously strengthen technological innovation and improve the intelligence level of LED large screen equipment.

[0003] At present, dual-system LED large-screen products on the market are usually equipped with two independent system management units, and the two modules share and synchronize data through the OPS interface. The existing solutions basically adopt one master and one slave technology, and two system management units need to be online at the same time when the system is switched; the operating system mainly involves Android and Windows systems, and there are relatively few products for LINUX, domestic Kirin, Tongxin and other systems.

[0004] Although the existing solution has improved system flexibility and software compatibility, it also has some disadvantages. First, the existing technology needs to integrate OPS computers, and the system must be online at the same time when switching, which greatly increases the hardware cost and energy loss of the product; secondly, 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, the existing solution increases the startup time and maintenance cost of the equipment. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present application provides a system, method and medium for realizing dual systems of a large LED screen, so as to solve the problem that the prior art needs to integrate an OPS computer and the systems need to be online at the same time when switching, which greatly increases the hardware cost and energy loss of the product; secondly, the Windows system is more susceptible to attacks such as Trojans and viruses, resulting in system crashes, data loss, and even affecting the normal operation of another system; finally, the existing solution increases the startup time and maintenance cost of the equipment.

[0007] The online learning method provided in the embodiment of the present application requires the integration of OPS computers in the existing solution, and the two systems need to be online at the same time when the system is switched, which increases the hardware cost (such as additional computer equipment, storage devices, etc.) and energy loss (such as power consumption). However, the present application designs a LED large screen dual system including a storage management unit, a system management unit, a power supply unit, an LED display unit and an information storage unit, so that the two systems can run and switch independently without adding additional hardware devices, thereby greatly reducing the hardware cost and energy loss. In addition, the existing solution uses the Windows system, which is vulnerable to attacks by malware such as Trojans and viruses, resulting in system crashes, data loss, and may even affect the normal operation of another system. The present application effectively improves the security and stability of the system by designing a dual system architecture and using a customized system. Even if one system is attacked, the other system can still maintain normal operation, ensuring the stability of the overall system and the integrity of the data. In addition, the existing solution requires the integration of multiple hardware devices and a complex system environment, resulting in a long device startup time and high maintenance costs.

[0014] In one implementation of the present application, after the storage management unit controls the control system management unit and the LED display unit are powered on, the method further includes: The storage management unit retrieves the operation instruction corresponding to the currently powered-on system storage unit from the information storage unit, and uploads it to the system management unit.
