Three projectors of three display terminals, can be controlled by master controller and pass through three and show from controller and three projectors
Terminal is shown, improves the efficiency of trial.
Brief description
Fig. 1 is the module diagram of law court's projection demonstration device in the embodiment of the present invention.
Specific embodiment
The embodiment of the present invention is passed through to provide a kind of law court projection demonstration device, solves transmission exhibit efficiency in prior art
Ratio is relatively low, the technical problem of impact trial efficiency.
In order to solve in above-mentioned prior art, below in conjunction with Figure of description and specific embodiment to above-mentioned skill
Art scheme is described in detail.
Embodiments provide a kind of law court projection demonstration device, as shown in figure 1, including three display terminals, masters
Controller 10, three projectors 20 of corresponding three display terminals, the wireless transceiver 30 connecting master controller 10 and main LED
Lamp group 40, connect the mike 50 of master controller 10 and speaker 60, display terminal based on the first display terminal A, the second display
Terminal B and the 3rd display terminal C are from display terminal, also include connecting the first of the second display terminal B from LED light group 401,
Connect the second of the 3rd display terminal C from LED light group 402, master controller 10 connects first from controller 101 and second from control
Device 102, three projectors 20 are all connected with master controller 10, and three display terminals are respectively arranged on sliding rail, and first is aobvious
Show that terminal A connects encoder.
In a particular embodiment, due to master controller 10 can by first from controller 101 and second from control
Device 102 is controlled showing, realizes three display terminals and shows respectively.The spectators of zones of different can see and being opened up for convenience
Exhibit showing etc. information, can correspond to three display terminals respectively by connecting three projectors 20 on master controller 10,
Content shown by these three display terminals can be shown on projection screen, facilitate other spectators by way of projection
Viewing.Each display terminal is all disposed within sliding rail, and sliding rail is specially opposing parallel track.
Master controller 10 includes power supply side and signal switching port.Achieve effective control.
By above-mentioned technical scheme, thus improve the efficiency of court's trial.
Although preferred embodiments of the present invention have been described, but those skilled in the art once know basic creation
Property concept, then can make other change and modification to these embodiments.So, claims are intended to be construed to including excellent
Select embodiment and fall into being had altered and changing of the scope of the invention.
