Along with popularizing of science and technology development and computer, the computer lantern slide is very extensive in the application in fields such as teaching, product demonstration.Demonstrator needs to operate before computer in person or need other people to help just can finish whole presentation process usually at present, and this has brought a lot of troubles to demonstrator.Also Related product such as wired/wireless mouse on the market, but use inconvenience and cost higher relatively.
Three, summary of the invention
The purpose of this utility model provides a kind of easy to use, demonstrator and need not the infrared computer remote-control device that before computer operation just can be finished whole presentation process, and this device can be accomplished the demonstration effect that some are special simultaneously.
The purpose of this utility model is achieved like this: a kind of infrared computer remote-control device, it is characterized in that: it comprises radiating portion, receiving unit and controlling computer, described radiating portion is made up of keypad, coding, modulator and infrared transmitter, coding, modulator are accepted the signal of keypad, and the signal after ovennodulation is exported by infrared transmitter; Described receiving unit is made up of infrared remote receiver, demoder and USB (universal serial bus) (USB) transceiver, infrared remote receiver receives the signal of infrared transmitter output, and signal passed to demoder, flow to controlling computer through decoded signal by the USB transceiver.Include USB interface in the USB transceiver, USB interface is connected with controlling computer.
In the utility model, more convenient for using, in radiating portion, be provided with generating laser, can play the effect of electronic teacher pointer.Radiating portion can be the hand-held remote controller form, and generating laser can be arranged on the laser lamp in the telepilot.
In the utility model, the C1 of keypad, C2, C3, C4, L1, L2, L3, L4 interface are connected with C1, C2, C3, C4, L1, L2, L3, L4 interface in coding, the modulator respectively in the radiating portion; 1 interface in coding, the modulator is connected with infrared transmitter with 22 interfaces.The OUT1 interface of infrared remote receiver is connected with OUT1 interface in the demoder in the receiving unit; The corresponding interface in the demoder is connected with corresponding interface in the USB transceiver; USB interface CON4 in the USB transceiver is connected with controlling computer.
Use Infrared Ray Remote Control Technology and USB interface technology in the utility model, send the output signal of radiating portion to controlling computer, compared with prior art, the demonstrator hand-held remote controller can be finished all operations in the slide show process in the utility model, very easy to use, and can accomplish the demonstration effect that some are special, finish various demo functions, as preceding turn over, after turn over, amplification, volume control etc., make demonstration reach arbitrary effect.In addition, the built-in laser lamp of telepilot can play the effect of electronic teacher pointer.The utility model has the advantages that: easy to use, stable performance, installation is easy to carry, operation is succinct and cost is low.
Slide show is used very extensive at present, teaching demonstration, sales force as colleges and universities demonstrate the introduction of product, and use large, medium and small meeting of magic lantern or the like, any occasion that the slide show function is arranged, the utility model all can use, and it greatly facilitates slide show personnel's operation.The utility model not only can be used for slide show, can also be used to computer is carried out straighforward operation, brings convenience to people.
Four, description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is the utility model radiating portion circuit diagram;
Fig. 3 is the utility model receiving unit circuit diagram.
Five, embodiment
The infrared computer remote-control device of a kind of slide show described in the utility model comprises radiating portion 1, receiving unit 2 and controlling computer 3.Radiating portion 1 is the hand-held remote controller form, form by keypad 4, coding, modulator 5 and infrared transmitter 6, the input end of coding, modulator 5 is connected with keypad 4, output terminal is connected with infrared transmitter 6, it accepts the signal of keypad 4, and the signal after ovennodulation is exported by infrared transmitter 6.Receiving unit 2 is arranged in the computer, it is made up of infrared remote receiver 7, demoder 8 and USB transceiver 9, the input end of demoder 8 is connected with infrared remote receiver 7, output terminal is connected with USB transceiver 9, infrared remote receiver 7 receives the signal of infrared transmitter 6 outputs, and signal passed to demoder 8, and flow to controlling computer 3 through decoded signal by the USB interface in the USB transceiver 9, realize operation to slide show.
More convenient for using, can in hand-held remote controller, be provided with generating laser 10, generating laser 10 can be arranged on the laser lamp in the telepilot, can launch round dot laser and make indication usefulness to display screen, plays the effect of electronic teacher pointer.
In the present embodiment, remote-control transmitting part 1 adopts the infrared coding technology, and button can be launched the infrared signal of different coding and give infrared remote receiver 7 when pressing; Decoding draws different control commands to infrared coding by computer chip to accept part 2.This order is sent into computer by USB transceiver 9, finishes various control function by the driver that computer is installed.
The flow process that the utility model signal transmits is as follows:
After a certain button in the keypad on the hand-held remote controller 14 was pressed, circuit captured key value immediately and is encoded by scrambler 5, and coding is after launched by infrared-emitting diode after the modulation of 38KHZ signal.Button may command generating laser 10 is launched round dot laser in addition, the usefulness of giving instruction on giant-screen.
After receiving unit 2 is received infrared signal, after receiving a demodulation, send into microprocessor decoding 8, and control USB transponder chip is sent to controlling computer 3 with decode value.Key commands on the telepilot has just converted the control command of computer to like this.After computer is received control command, finish various control operations to slide show, as preceding turn over, after turn over, amplification, volume control etc., greatly facilitate the operation of the demonstrator of using magic lantern.
