Embodiment Construction

[0027] In the embodiment of the present invention, the mapping relationship between the control card mark and the control card is established and stored in advance, after the control system software is started, the control card parameters read in the internal memory are put into the temporary memory, and the control system then according to The mapping relationship calls the protocol interface provided by the control card manufacturer to transmit the required parameters to the corresponding control card, and then displays all the control card simulation icons on the same interface. At this time, the control card can be operated one step at a time.

[0028] See figure 1 , figure 1 It is the implementation flow of a LED display screen control method of the present invention, which is described in detail as follows:

[0029] Step S101, establishing and storing the mapping relationship between the control card label and the control card, mainly using the mapping table to establis...

Abstract

An LED display screen compatible with different types of control cards and its control system and method, the method includes the following steps: establishing and storing the mapping relationship between the control card mark and the control card; starting the control system software, reading the internal The control card parameters in the memory are put into the temporary memory; the control system calls the protocol interface provided by the control card manufacturer according to the mapping relationship to transmit the required parameters to the corresponding control card. Since the present invention establishes and stores the mapping relationship between the control card label and the control card in advance, each control card has a unique control card label, and calls the protocol interface provided by the control card manufacturer according to the stored mapping relationship during initialization. The required parameters are sent to the corresponding control card, so that different types of control cards can be controlled on the same software, and the operation is simple and error-free.

Description

technical field [0001] The invention relates to an LED display screen compatible with different types of control cards and its control system and method. Background technique [0002] In modern society, with the rapid development of science and technology, more and more LED displays are used in people's daily life. LED displays such as full-color LED displays, traffic variable speed limit signs, countdown boards, and Kanban management systems have No longer an uncommon product. [0003] The LED display control system is an important part of the LED display and also the core of the technology. At present, many excellent companies in the market are producing control chips for LED displays, but each control card manufacturer has its own operating procedures for each control card. In large projects, it may be installed To more than dozens of LED displays with different types of control cards, the current practice is to install operating programs from different manufacturers in...
