Embodiment Construction

[0027] In the present invention, the mobile device 1 can update the program content and parameters of the LED control card, benefiting from the wide application of the MTP protocol. The MTP protocol is Media Transfer Protocol, and the media transfer protocol is based on the extension of the PTP (Picture Transfer Protocol) protocol. It is mainly used to transmit media files, and its valuable application is the license for synchronizing DRM files. Based on the fact that the mobile device 1 supports the MTP protocol, the present invention achieves the purpose of asynchronously controlling the LED screen by the mobile device 1 by improving the mobile device 1 and the LED control card. The substantive features of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] like figure 1 Shown is an asynchronous control system for updating LED screen contents disclosed by the present invention, which includes...

Abstract

The invention discloses an asynchronous control system and an asynchronous control method for using a mobile device to update the content of an LED screen. The system comprises a mobile device, a control card device, and a connecting device for connecting the mobile device and the control card device. The mobile device is provided with a processing module and a data export module, the processing module is used for processing content needing updating, and the updated content is exported by the data export module. The control card device is provided with a mobile device identification module for access identification and a parsing module, and after the parsing module parses the content needing updating, the content is played on a related LED screen under control. The method comprises the following steps: the content for updating an LED screen is edited on a mobile device; the mobile device and a control card device are connected using a USB data cable; the control card device identifies the mobile device; the control card device traverses the files of the mobile device, and searches for a feature file; the control card device parses the feature file; and the control card device updates the content played on the related LED screen. The asynchronous control system and the asynchronous control method have the advantages of simple control process, diversified control modes, low cost, and the like.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an asynchronous control system and method for updating LED screen content with a mobile device. Background technique [0002] At present, mobile devices are becoming more and more popular, and customers have increasingly strong demands on using mobile devices to control various devices. There are also some LED display control systems on the market, which introduce mobile APP to control the display. [0003] But currently it is limited to updating control card parameters and media content through WiFi and U disk. Updating through WiFi requires additional network equipment support, while updating through U disk, and because the platforms of mobile devices are quite different, different systems support differently, and some even do not support it. Contents of the invention [0004] In order to solve the limitations of the prior art, the present invention provides an asynchrono...
