Method and device for automatically setting id of LCD splicing screen

Abstract

The invention discloses an automatic ID setting method for LCDs. The automatic ID setting method comprises the following steps: sequentially connecting all LCD units in series in preset order to enable every two LCD units to realize information communication; after selecting one of the LCD units as a starting unit, setting the ID value of the starting unit; respectively sending the ID value by the starting unit to the LCD units connected in front of and behind the starting unit; in each sending direction, increasing the ID value by each LCD unit according to the preset increasing law to serve as the ID value per se after receiving the ID value, and sending the increased ID value by each LCD unit to the next LCD unit in the sending direction till the increased ID value is sent to the last LCD unit. The invention also discloses an automatic ID setting device corresponding to the automatic ID setting method, by the adoption of the automatic ID setting method and device, the ID sequence numbers of all the LCDs can be automatically, quickly, accurately and conveniently set.

Description

technical field [0001] The invention relates to the technical field of screen splicing and display, in particular to a method and device for automatically setting an ID of a liquid crystal splicing screen. Background technique [0002] The most important application of LCD splicing screen products in the industry is "splicing", that is, multiple splicing screens display a signal image together. Before completing the splicing operation, it is necessary to specify which splicing screens are combined to display a complete picture. , you must complete the setting of the splicing function by selecting the ID serial numbers of these splicing screens. Before the whole LCD splicing screen leaves the factory, the ID number of each splicing screen is the same. During on-site construction, it is necessary to adjust the dial switch value of each screen or set the independent ID of each single screen through infrared signals, so that all screens in a project have different ID serial num...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, no matter whether the ID value is set through the dialing method or the infrared signal receiving method, since there is no communication between the splicing screen units, it is necessary for the on-site construction personnel to manually carry out each splicing screen unit one by one. Setting, not only the workload is relatively large, but also it is easy to configure the same ID value for two or more single screens. In addition, when doing the above configuration, it is necessary to pre-set the ID of each single screen before performing large-scale The construction of the screen, because once the large screen has been placed on the bracket, it is more difficult to adjust, because in general projects, the large screens are installed on top of each other, the height is relatively high, and it is not easy to operate after installation

[0006] The main problem of the existing technology is that ID values ​​need to be manually configured one by one. It is very easy to configure multiple single screens with the same ID value during the setting process, resulting in unavailable splicing services.
