Description
Technical field
The utility model belongs to electronical display control technology field, and in particular to a kind of flat-panel screens control system.
Background technology
Flat-panel screens is widely used in the fields such as various safety monitorings, advertisement putting, video conference, traffic administration.It is existing
Use of the technology for flat-panel screens needs a vision signal input line, and a control line to complete, such control
Structure processed just needs at least two signal wires to realize that control to flat-panel screens uses, and the use of wire rod will increase flat
The use cost of face display system.
The control of existing flat-panel screens needs a vision signal input line, and a control line or infrared (wireless)
Controller is completed (as shown in Figure 3), such control signal wire and video signal cable disunity, for multichannel flat panel display system
For (as shown in Figure 4), every piece of screen be required for two control signal wires realize individually control display, modern times monitoring security protection
Field generally requires many block flat-panel screens to form whole system, and the wire rod so to be used will be very more, in engineering
In wiring, installation and debugging, wire rod is more, and system installation also can be more troublesome.And due to using different signal wires, just it can also lead
Cause can not unifying for flat-panel screens system and control system, that is to say, that flat-panel screens software and flat-panel screens control are soft
Part needs different clients to complete, and so also results in and is using upper inconvenience, needs volume for layman's operation
Outer training, these all adds additional the use cost of whole system.
Utility model content
The purpose of this utility model is to provide a kind of flat-panel screens control system, by control signal wire and video signal cable
Unified, the wire rod for reducing half uses, while accomplishes the unification of control system and display system, for operating personnel significantly
Reduce operation difficulty.
The utility model provides following technical scheme：
A kind of flat-panel screens control system, includes the control terminal and screen of interconnection, and the screen connects provided with HDMI
Mouthful, the HDMI is provided with SCL pins and SDA pins, the control terminal by same signal wire connect the SCL pins with
The SDA pins, the SCL pins are used for transmission reference clock, and the SDA pins are used for transmission of control signals.
Preferably, the control terminal is splicer, and the splicer connects the SCL pins and institute by the signal wire
SDA pins are stated, realize the control to screen and the reading of information.
Preferably, the screen includes screen parameter module and screen control unit, and the splicer is drawn by the SCL
Pin and the SDA pins connect the screen parameter module and the screen control unit respectively, realize same signal wire screen
Parameter is read and control.
Preferably, the quantity of the screen is at least one, and the control terminal is connected with each other with the screen simultaneously, can be with
Multiple screens are controlled simultaneously, data exchange is carried out with multiple screens.
The beneficial effects of the utility model are：Original video line and control line is unified, reduce half wire rod and use, greatly
Reduce the cost greatly；Video signal cable and control signal wire is unified into single line material, realize to the single of flat-panel screens
Line traffic control is shown, so that the video processor of control terminal and control screen software can be integrated together, reduces control terminal
Operation difficulty；Simultaneously because control signal by HDMI with vision signal unification to single line, being connected, it is only necessary to change
The driving plate of flat-panel screens, it is other to change, reduce R＆D costs.

Embodiment
As depicted in figs. 1 and 2, a kind of flat-panel screens control system, the control terminal and screen of interconnection, screen are included
Provided with HDMI, HDMI is provided with SCL pins 1 and SDA pins 2, and control terminal connects SCL pins 1 by same signal wire
With SDA pins 2, screen includes screen parameter module and screen control unit, and control terminal is divided by SCL pins 1 and SDA pins 2
Not Lian Jie screen parameter module and screen control unit, realize that same signal wire screen parameter is read and control.
As depicted in figs. 1 and 2, modern flat-panel screens mostly supports HDMI standard, HDMI (High
Definition Multimedia Interface) HDMI is a kind of digitized video COBBAIF skill
Art, can be with simultaneous transmission video and audio signal.The utility model utilizes 15,16 pins (SCL, SDA) in HDMI,
SCL is used for transmission reference clock, and SDA is used for transmission of control signals.Originally this both threads is used for the parameter of transport plane display
To control terminal, after control terminal reads flat-panel screens information, this both threads can be in and wait idle condition.The utility model profit
With this characteristic, this two lines for being in idle condition are borrowed, send control command, when control terminal has read flat-panel screens letter
After breath, control terminal control plane display is used further to.
As shown in Figure 5 and Figure 6, control terminal is splicer, and splicer connects SCL pins 1 and SDA pins 2 by signal wire,
The control to screen and the reading of information are realized, the quantity of screen is at least one, and control terminal is connected with each other with screen simultaneously, can
To control multiple screens simultaneously, data exchange is carried out with multiple screens.Control terminal can pass through SDA, SCL after electricity in flat-panel screens
Flat-panel screens parameter is read, is now also connected simultaneously with flat-panel screens control unit, but flat-panel screens control unit
In holding state, control terminal is not influenceed the parameter of flat-panel screens is read.After waiting parameter reading, control terminal is right again
Flat-panel screens control unit sends control command.So ensure that and video and control are transmitted on same root signal wire
Signal.Simultaneously because control signal in control terminal with vision signal unification to single line, so also only needing a client
Software can just realize transmission of video and the control to flat-panel screens simultaneously.
The control method of described flat-panel screens control system：
S1：On screen after electricity, control terminal reads the parameter in screen parameter module by SCL pins and SDA pins, simultaneously
It is connected with screen control unit, screen control unit is in holding state；
S2：After control terminal reads parameter, then control command is sent to screen control unit, that is, ensure to believe in same root
Video and control signal are transmitted on number line；
S3：Screen control unit receives the control command from control terminal, after being shown according to control command, screen ginseng
Digital-to-analogue block passes screen parameter back control terminal by SCL pins and SDA pins.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, although ginseng
The utility model is described in detail according to previous embodiment, for those skilled in the art, it still can be with
Technical scheme described in foregoing embodiments is modified, or equivalent substitution is carried out to which part technical characteristic.It is all
Within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., this practicality should be included in
