Remote LED display screen display content custom control method

Abstract

The invention discloses a remote user-defined control method for display content of an LED display screen. The method comprises the following steps that S1, pre-control equipment is selected through a Web terminal, and an LED dot matrix space of a display interface is determined; s2, selecting a standard pattern in a program database through a Web end or customizing a new pattern in a drawing tool to serve as display content; s3, the display content in the step S2 is mapped to the LED dot matrix space in the step S1, and a control instruction is formed; s4, the Web end transmits the control instruction in the step S3 to a vehicle-mounted control end of the pre-control equipment through a Web server; and S5, the vehicle-mounted control terminal updates the display content of the LED display screen according to the received control instruction. Display content is conveniently defined based on a drawing tool, pre-control equipment is rapidly selected through the Web end, operation is easy, control is convenient, the system can automatically achieve display brightness configuration, conversion of control instructions between different equipment models is completed through the Web server, and the system can be effectively used for a mobile traffic information display screen control system.

Description

technical field [0001] The invention relates to a remote control technology of an LED display screen, in particular to a method for customizing the display content of a remote LED display screen. Background technique [0002] With the acceleration of urbanization, the requirements for transportation facilities are getting higher and higher. For intersections that require temporary traffic guidance, mobile traffic information display screens have been widely used. [0003] Existing mobile traffic information display screens are usually implemented with low-resolution LED screens. For example, the applicant has also proposed a mobile traffic information device with patent application number 201320387686.5. The content of the display screen can be controlled by the controller Control, can display Chinese characters, various common characters, graphics and traffic sign information, with rich display content, and can adapt to various contingency conditions according to the conges...

Problems solved by technology

[0004]However, the defect of the existing technology is: for different types of display screens, the control commands corresponding to the display content often need to be configured by the lower computer, and usually only display Standardized graphics or characters, low level of intelligence that can be customized by users, as the number of equipment distribution increases, the distribution area becomes wider and wider, making it difficult to quickly realize remote centralized management
