The blank of shadow machine function.
Background technology
Projecting apparatus, also known as projector, which are one kind, can project image or video equipment on curtain (blank), can be with
It is connected by the different same computers of interface, VCD, DVD, BD, game machine, DV etc. and plays corresponding vision signal.
Projector is due to the use of convenient, and image frame can adjust larger, and image displaying quality is fine, it is important that price
Cheaply, it is widely used in the even professional theater of business meetings, education, home theater.
Currently, whether in the parlor of meeting room, classroom or family, the film playback Room of movie theatre etc., these places are substantially
Projector is mounted on the floor on roof, in the parlor of meeting room, classroom or family, before film playback Room of movie theatre etc.
The blank (curtain) of one projection of installation, on projector to blank, people watch the projection on blank.
In this way, being operated to projector, the remote controler of projector is generally used, currently, projection set remote-controller and family
The same with TV remote controller, remote control process and remote control principles are also almost the same, are all (distant using an infrared transmitting device
Control device) remote control command is generated, remote control command is modulated on infrared ray and is sent, there are one infrared in projector main frame one end
Line reception device, it is demodulated after receiving infrared-ray signal, control command is obtained, projector main frame is completed control command and wanted
The action asked, such as booting, shutdown, selection projection pattern, adjustment projection pattern, also home television set remote control process is consistent.
But the ground such as meeting room, classroom, unlike places such as families, personnel are relatively more, remote controler is often inconvenient to preserve, and holds
It is easy to be lost.Once remote controler is lost, it may result in projector and cannot be started up, influence entire blank answering in meeting teaching etc.
With.
In order to overcome remote controler to be easily lost caused deficiency, existing method is to connect blank and projection with serial ports
Machine, blank are said the word by serial ports to projector, its switch is controlled.But it needs additionally to increase a Serial Port Line.
Utility model content
The purpose of this utility model, which is to provide, to be provided under the premise of one kind can not increase additional wire rod, and projection can be controlled
The blank with remote controlled projection machine function of machine.
The utility model is technical solution used by realizing its purpose of utility model：A kind of band remote controlled projection machine function
Blank, including blank ontology is additionally provided with the remote control unit being remotely controlled to projector on the blank ontology, described
Remote control unit include the remote host being arranged on blank, be arranged in the touch key-press of whiteboard surface and inside the blank
Against the remote control signal transmission device of the projector；The order of the output end and remote host of the touch key-press inputs
Interface port is connected, and the remote signal emission port of the remote host connects the remote control signal transmission device.
In the utility model, infrared remote controller is built into the circuit of blank, using with remote controlled projection machine function
Blank realization is remotely controlled projector, will not make troubles since remote controler is lost.
Further, in the above-mentioned blank with remote controlled projection machine function：The remote control unit is infra-red remote control list
Member, remote control signal transmission device are mounted on blank body interior against the infrared emission tube of the projector.
Further, in the above-mentioned blank with remote controlled projection machine function：The touch key-press is arranged in blank ontology
Front sends corresponding control code to projector when hand touches certain function button.
Further, in the above-mentioned blank with remote controlled projection machine function：The remote host includes generating remote control life
The microcontroller of order and the driving device for emitting remote signal amplification by remote control signal transmission device.
The utility model is further detailed in the following with reference to the drawings and specific embodiments.
Description of the drawings
Fig. 1 is 1 functional block diagram of the utility model embodiment.
Fig. 2 is 2 functional block diagram of the utility model embodiment.
Fig. 3 is the logical flow chart of 2 blank remote controlled projection machine of the utility model embodiment.
Fig. 4 is the circuit diagram that specific remote control scheme is implemented.
Specific embodiment
Embodiment 1, as shown in Figure 1, the present embodiment be it is a kind of can to the blank that projector main frame is remotely controlled, be remotely controlled throw
The booting of shadow machine, shutdown, selection projection pattern etc., as shown in Figure 1, the blank with remote controlled projection machine function of the present embodiment, including
Blank ontology, is additionally provided with the remote control unit being remotely controlled to projector on blank ontology, and remote control unit includes being arranged white
Remote host on plate is arranged in the touch key-press of whiteboard surface and emits against the remote signal of projector on blank
Device.
Remote host is the core of the present embodiment, and in order to save development cost, in the present embodiment, remote host is using current
The circuit of the remote host of hand-held remote controller, that is to say, that by the remote host circuit design of the remote controler of former projector in blank
On, the advantage of doing so is that using the remote control circuit of original projector itself, any exploitation need not be carried out to remote signal, thrown
Shadow machine itself has any improvement without due to needing suitable blank to be remotely controlled it, it is only necessary to directly be clicked on blank
Touch key-press can.
The output end of touch key-press is connected with the command input interface port of remote host, and touch key-press can in the present embodiment
To be arranged on the surface of blank, in one, the surface of blank specific region, such as on some angle, according to hand-held remote controller panel
Some key areas of content setting are arranged to corresponding press key contents in corresponding key area.Key information is received, then will
These key informations received are sent to remote host, and remote host generates the letter of different coding according to the key mapping information pressed
Number, it then modulates the signals onto on infrared ray, emitter is emitted.
Remote control signal transmission device is a kind of infrared transmitting device, currently, the remote-controlled launcher on trick remote controler
It is a kind of infrared light-emitting diode, in the present embodiment, the suitable such infrared ray hair of place installation one inside blank
Optical diode, infrared light-emitting diode connect the remote signal emission port of remote host, and the remote signal of remote host is sent out
