Description

Multichannel expanded type multi-screen splicer

Technical field

The utility model relates to areas of information technology, utilizes video control technology to monitor in real time and Real time displaying the running status of industrial electromechanical equipment.

Background technology

Traditional multi-screen splicer is simple processing the splicing of picture or video, and also at outside configuration signal conversion equipment, like this when containing much information, will can produce synchronism problem for unlike signal.Therefore, create advanced person, high definition, smoothness, seamless, multi-signal processes and displays can be carried out, the large screen splicing device that collection multiclass human users is controlled in one is very necessary.

Utility model content

For solving the problems of the technologies described above, providing a kind of multichannel expanded type multi-screen splicer, can carry out with entering processes and displays the multiple signals of video matrix, and there is expanded function, supporting that more video inputs export.

For realizing above-mentioned technical purpose, the technical scheme adopted is: multichannel expanded type multi-screen splicer, be provided with splicer mainboard, splicer mainboard is provided with 11 pieces of input draw-in grooves, 10 pieces export draw-in groove and one piece of control draw-in groove, every block input draw-in groove, export draw-in groove and control draw-in groove is equipped with two groups of clamps, the clamp of input draw-in groove is equipped with HDMIIN, VGAIN, VIDEOIN and DVIOUT tetra-kinds of terminals, the clamp exporting draw-in groove is provided with the lead-out terminal matched with the clamp inputting draw-in groove, the vision signal of the clamp receiver, video matrix of input draw-in groove, the clamp exporting draw-in groove is connected with Mosaic screen by data wire, the clamp controlling draw-in groove is connected with main control system.

The clamp of control draw-in groove described in the utility model adopts RS232 serial ports.

Splicer described in the utility model is expanded type splicer, is contacted by the clamp of both control draw-in grooves between splicer and splicer by data wire, realizes expansion.

The major technique advantage of this product and in the past product is as follows:

(1) no longer need additional configuration signal processor, product inherently has the signal input function supporting multiple format, solves signal synchronism problem.Comprise composite video CVBS, digital high-definition video HDMI1.3 (HDCP1.3), analogue computer signal VGA, digital computer signal DVI1.0 etc.

(2) the input and output summation on unit the highest support 24 tunnel, and the function with multimachine cascade use.Containing RS-232in and RS-232OUT interface on controller, RS-232OUT is the expansion to computer serial port, can next controller of cascade or matrix.

(3) output port of output board is DVI and VGA and deposits, and output resolution ratio is up to 1920 X 1200@60HZ.Automatic calibration can be carried out, filtering decoding etc. to unlike signal.

Embodiment

Multi-screen splicer belongs to pure hardware configuration, without operating system, includes tablet, output board, signal processor, client and signal source.The tablet of described controller and output board are respectively 12 pieces and 11 pieces, and each block is actual comprises two groups of input and output clamps; The compatible DVI of HDMIIN(is had above every block clamp), VGAIN, VIDEOIN, DVIOUT (comprising VGA) four terminals.After described signal source is inputted by tablet, can roam arbitrarily on large-screen through signal processor (control card), zoom in or out picture.Described output board is directly connected with large-screen, realizes the output of splicing signal.Concrete signal handling process is: according to splicing instruction and the son screen Splicing model of client, control unit in splicer transfers to primary processor by switch, primary processor according to client demand to transferring in each sub-processor after the video image decoding received, sub-processor application edge shield technology carries out cutting cutting to image, demonstrates indeformable video image in screen.Splicer adopts the RS232 serial ports of main flow to control, and has RS232 serial ports expanding function, facilitates the cascade Mach-Zehnder interferometer of system miscellaneous equipment.

One, multi-screen splicer internal structure describes:

Multi-screen splicer splicing mainboard has 11 pieces to input draw-in groove, 10 pieces of output draw-in grooves and one piece of control draw-in groove, and every block draw-in groove can include two groups of inputs, output, Control card.Include DVI signal input interface and AV vision signal access port in input card, receive the vision signal from monitoring camera, industrial computer and network; Output card includes DVI signal output, is connected with large-screen splicing wall; Control card adopts S232 serial ports, for regulating and controlling the vision signal of input, or the multiple splicer of cascade.Inserting and link the input signal connect, can be any one in HDMI, DVI, VGA, VIEDO.All signals of input, by the distributional effects of splicing mainboard, can be presented at the optional position of combination.(if VGA exports, DVI must be used to turn VGA connector).

Two, multi-screen splicer system configuration describes:

The topological structure of system is divided into matrix form and non-matrix formula.Matrix type structure refers to that the vision signal such as video-frequency monitor, DVD is transferred in splicer by video matrix, or device data acquisition picture on computer or industrial computer or satellite display figure are transferred in splicer by rgb matrix.Computer signal is shown in mosaic screen by general conventional VGA mouth, also video matrix delivery outlet can be accessed simultaneously A plate BNC mouth, the arbitrary placement in mosaic screen by camera image or computer picture.Non-matrix formula structure refers to and uses one or more RGB data capture card to replace rgb matrix.When system connection server or network, data-signal, by switch, is transferred in network decoder, is then transferred to multi-screen splicer, large-screen shows.

Main control system adjusts the quantity of display frame, mode, and large-screen shows.Main control system, by RS232 serial ports and splicer and computer communication, comprises: selection PORT COM, its parameter includes port, baud rate, data bit, check digit, position of rest etc.

If control software design is without operation after start, so controller can recover the scene of windowing before shutting down for the last time, if now respective window no signal input, then and combination display blank screen; If without any image window before last shutdown, then combination shows built-in base map, normally a width world map.
