Abstract
The utility model discloses a remote controller for playing a slideshow, which belongs to the field of wireless remote controllers. The remote controller for playing the slideshow comprises an emitter and a receiver, wherein the emitter comprises a slide-turning function button, an encoding unit, a converter used for converting an electronic signal into a wireless signal and an antenna used for emitting the wireless signal, which are connected in sequence; the receiver comprises a wireless receiving device, a decoder and an interface converter, which are connected in sequence; the input terminal of the interface converter is connected with the output terminal of the decoder and the other end of the interface converter is connected with a computer; and the emitter is powered by a battery arranged inside the emitter; and the receiver is directly powered by the control wire of the port of the computer. The remote controller for playing the slideshow is characterized in that a laser head is arranged inside the emitter which comprises a laser diode driving circuit and a laser diode and is connected with a laser emission switch arranged correspondingly on the face plate. The remote controller for playing the slideshow can control the computer to turn up and down the slides and achieves the integration of playing control and laser indication.
Description
[technical field]
The utility model relates to a kind of Digiplex, the wireless remote control when particularly being applicable to lantern slide playing.
[background technology]
Along with Development of Multimedia Technology, projector replaces blackboard gradually, and the teacher utilizes the software development courseware, shows the important way that becomes modernizing teaching by projector.And in the present lantern slide playing, often need the teacher with mouse or keyboard closely page turning and the action of carrying out lantern slide of operational computations machine switch, the activity space that has limited to speaker self, widened the direct contact distance of teacher and student, having limited some needs the carrying out of object operation demonstration simultaneously.In addition, usually can use laser pen in the explanation of lantern slide, for the teacher, be used alternatingly two equipment of mouse and laser pen during concrete operations, very inconvenience.
[summary of the invention]
Technical assignment of the present utility model is at above the deficiencies in the prior art, provides a kind of simple in structure, easy to use, arbitrarily controls presentation process and can adopt laser pen to explain the telepilot of prompting.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of lantern slide playing telepilot, constitute by transmitter, receiver, transmitter comprise page-turning function button, coding unit, with electronic signal be converted to wireless signal converter, send this wireless signal antenna continuous in proper order; Receiver is continuous in proper order by radio receiver, demoder, interface convertor, the output terminal of the input termination demoder of interface convertor, another termination computing machine of interface convertor; Transmitter is by powered battery in the transmitter, and receiver is directly powered by the control line of computer port.It is characterized in that transmitter is built-in with a laser head, comprise laser diode driver circuit, laser diode, be connected with Laser emission switch on the panel of relative set.
Above-mentioned transmitter can have ESC button and corresponding encoded unit, realizes withdrawing from or cancelling function.
Can adopt the infrared-ray communication mode to carry out transmission of wireless signals between above-mentioned transmitter, the receiver.
Can transmit upper and lower page turn information to computing machine by the utility model, thereby saved the trouble of when utilizing lantern slide to impart knowledge to students, operating with computer keyboard or mouse, make that the teacher can be free within the specific limits movable, thereby can be better and student's interaction, communication, strengthen the classroom interest.Meanwhile, in use, except control lantern slide playing process, the utility model has also been realized the integrated of Play Control and laser indication, uses the laser indication to point out and explain, and is practical, can be widely used in electronic teaching.

Fig. 3 is a receiver architecture theory diagram of the present utility model.
[embodiment]
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, 2, the utility model mainly is made of transmitter, receiver.In the present embodiment, the transmitter housing grips for the user, and housing is lip pencil, and the surface is provided with function button and switch, and page-turning button also can be substituted by roller.Transmitter is arranged in this housing, normally is arranged on the circuit board.Transmitter mainly comprises coding and two modules of modulate emission, the page-turning function button, coding unit, electronic signal is converted to the converter of wireless signal, the antenna that sends this wireless signal is continuous in proper order, the variation of page-turning function button position produces a corresponding signal, coding unit is taken a sample the signal that is sent and encoded, form electronic signal, received this electronic signal and be converted to the infrared and radio signal that meets radio transmission protocol of certain frequency by converter, this wireless signal is sent to antenna and is emitted to the receiver that is connected to the computing machine USB port.Transmitter is by being arranged at powered battery in this housing.
Shown in Fig. 1,3, receiver mainly comprises receiving demodulation, decoding and transport module, and is continuous in proper order by radio receiver, demoder, interface convertor, the output terminal of the input termination demoder of interface convertor, another termination computing machine of interface convertor.Receiver is directly powered by the control line of computer port.Its process mainly is to be divided into wireless signal to be converted to digital signal and to exchange two parts with computerized information, receiver is through after receiving wireless signal, receive by radio receiver is corresponding, utilize demoder with the signal of required fixed frequency through processing and amplifying, convert digital signal to, send into computing machine by the interface convertor transmission and carry out message exchange.In computing machine, by drive software detection port data, judgement button, send press key message then, thereby realize realizing the operation of page turning in the lantern slide playing by the page-turning function button, realize withdrawing from of lantern slide playing or cancel function by the ESC button.
Simultaneously, transmitter is built-in with a laser head, comprises laser diode driver circuit, laser diode, and is provided with a switch it is controlled, and can realize explaining prompt facility.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the utility model claim.
