Window controller and control method based on large-screen liquid crystal splicing display

Abstract

The invention discloses a windowing controller based on tiled display of large-screen liquid crystal and a control method thereof. The windowing controller comprises an input module, an output module, a signal switching module and a signal processing module. The input module comprises at least one signal input board. The output module comprises a plurality of signal output boards. The windowing controller further comprises a control module. The control module is connected with the signal switching module and used for receiving a windowing instruction of a user, generating a corresponding control signal according to the windowing instruction and transmitting the control signal to the signal switching module. The signal switching module controls the signal processing module to process the multimedia signal input by the input module, and controls the output module to output the processed multimedia signal. According to the windowing controller, tedious wiring between an external control platform and the windowing controller is avoided, and therefore the windowing controller is more convenient and easier to use; the control module in the windowing controller is used for controlling the tiled display of the large-screen liquid crystal, and therefore the windowing controller is fast to use and stable.

Description

technical field [0001] The invention relates to the field of large-screen liquid crystal splicing display, in particular to a window opening controller based on large-screen liquid crystal splicing display and a control method thereof. Background technique [0002] LCD splicing is a specialized terminal display device specially designed for engineering applications. Most of the window controllers used now are controlled by an external control platform. For example, the control host is connected to the window controller through the network, WIFI connection or RS485, RS232, so as to use the control software platform installed on the control host. to control the window controller. [0003] In this way, the control host needs to pass the converter from RS232 to RS485, and then connect to the window controller by the control line, and the on-site wiring is cumbersome and complicated. Moreover, this control method by sending the control protocol to the window controller is also ...

Problems solved by technology

[0003] In this way, the control host needs to be connected to the window controller through the RS232 to RS485 converter, and then the control line is connected to the window controller. The field wiring is cumbersome and complicated.

Moreover, this method of controlling the host computer by sending the control protocol to the window opening controller is not conducive to secondary development, and requires relatively high technical expertise for the operator, while the large-screen splicing window opening controller directly faces the Ordinary monitoring personnel, who often don't know much about professional knowledge, need a more easy-to-use, easy-to-understand, and intelligent window controller

In addition, the control software used by customers also comes from the software platform carried by the window controller when it leaves the factory, and cannot be updated to the latest software platform in real time. The intelligent expansion of the large-screen LCD splicing display system is also limited by the hardware of the current window controller. Restrictions, subsequent upgrades of the system cannot be completed
