Abstract
The utility model discloses a multimedia remote controller, which is characterized by comprising a remote control transmitting end and a receiving end, wherein the remote control transmitting end is provided with a laser transmitter and a laser transmitter control switch, the laser transmitter is embedded inside the remote control transmitting end, the receiving end is formed by a universal serial bus (USB) keyboard control chip, a USB interface and a wireless receiving module, and the remote control transmitting end can move freely. The multimedia remote controller can be used for fulfilling the functions of page-up turning, page-down turning, slideshow, stopping, program switching and the like; a near-distance teaching rod function is realized by a rod antenna, a far-distance teaching rod function is realized by a laser head, and the remote control distance is more than 500 meters; and the multimedia remote controller has the advantages of application of the USB interface, no need of driving, small and exquisite appearance, plug and play performance and great market potential.
Description
Technical field
The utility model relates to a kind of multimedia teaching aid, relates in particular to a kind of multimedia remote controller, to be convenient for people to use when PPT demonstrates.
Background technology
Multimedia ppt teaching has been widely used in various occasions; Like occasions such as teaching, speech, hotel, public lecture and technical training, but in actual application, there are some problems, must be like teacher near computation ppt; Can not be away from computer; This just makes teacher not to be dissolved among the student and goes, and influences communicative effect, has brought inconvenience; Some professors expert have asked the assistant to operate ppt when holding large-scale speech specially, but produce mismate sometimes, phenomenon not on one's beat, also caused waste of manpower resource simultaneously.Thereby, need badly a kind of can remote operated multimedia equipment.
The utility model content
The technical matters that the utility model will solve is: in order to overcome the problems referred to above, a kind of multimedia remote controller is provided, it can remote-controlled operation, makes things convenient for the PPT demonstration.
The utility model solves the technical scheme that its technical matters adopted: a kind of multimedia remote controller; It is characterized in that: comprise remote-control transmitting end and receiving end; The remote-control transmitting end has generating laser and generating laser CS; Generating laser is embedded in remote-control transmitting end inside, and receiving end is made up of USB keyboard control chip, USB interface and wireless receiving module, and the remote-control transmitting end can move freely.
Described remote-control transmitting end is provided with five function buttons, is respectively last turnover key, following turnover key, projection button, stops key and the program switching key.
Described remote-control transmitting end is provided with telescopic antenna.
Described receiving end is by the USB port power supply of computer.
The beneficial effect of the utility model is: by the partial function of generic USB keyboard; And combine with wireless receiving module; Realized the operated from a distance function; Because of the electronic switching circuit of remote control receiving unit belongs to parallelly connected relation with the circuit of keyboard chip internal, so the inner integrated remote control receiver module of receiver has no effect to the normal function of computer equipment, so page turning slideshow about can accomplishing in use, stop and function such as program switching; Closely teaching the bar function to realize, then realizing that by laser head remote control distance is greater than 500 meters at a distance by telescopic antenna; Use USB interface, need not to drive, small and exquisite, plug and play has very big market potential.
Description of drawings
Fig. 1 is the utility model external structure synoptic diagram;
Fig. 2 is the inner theory of constitution figure of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
As shown in Figure 1, the utility model has installed remote control receiver module 5 additional on the basis of original USB keyboard control chip, accomplished the respective remote operating function; Wherein telescopic antenna 1, not only can be used as telepilot antenna transmitted radio signal but also can closely the time, use as the religion bar; Generating laser 2 can be used as remote religion bar and uses; Function button 3 can be accomplished functions such as page turning up and down, program switching and PPT show, stop by Remote; Generating laser CS 4, convenient control generating laser; Wireless receiving module 5, supporting signal is encrypted, and prevents the phase mutual interference between every complete equipment, receives the control signal from the remote-control transmitting end, accomplishes function corresponding; USB keyboard control chip 6.
Concrete implementation procedure is like Fig. 1, shown in 2: after receiving end is inserted into the USB interface on the computer, get electric operate as normal; Be embedded into inner wireless receiving module from the USB interface power taking, in running order, its output terminal is an electronegative potential; This moment, triode was in cut-off state, and electronic switch is equivalent to cut out, behind the function button of pressing the remote-control transmitting end 3; Radio signal is gone out by telescopic antenna 1 diffraction, and the inner wireless receiving module 5 of receiving end receives the signal from the remote-control transmitting end, and its corresponding ports presents noble potential; The transistor base current potential that link to each other with this port this moment uprises triode conducting, the state that electronic switch is in out; Two contacts parallelly connected with transistor collector and emitter are equivalent to short circuit, promptly are equivalent to the action of pressing of keyboard, thereby accomplish remote-operated process.Generating laser 2 can serve as the function of teaching bar when remote-controlled operation.
The utility model adopts USB interface, need not to drive, and plug and play, remote control distance is about 500 meters; Make simply, with low cost, the brief practicality of function; Dependable performance is compared with the laser pen on the market and to be had advantageous functionality advantage, has made things convenient for ppt teaching and necessary operated from a distance.Be used for PowerPoint, page turning up and down, the broadcast of lantern slide stops; The RF remote-controlled design of RF need not be aimed at receiver, really embodies wireless freedom; Can be in 500 meters scopes random PowerPoint, need not be equipped with the special messenger and operate PC or notebook, bulletin demonstration, classroom instruction only need a people just can easily settle; Exquisite appearance, easy to carry.Being fit to occasions such as school, hotel, government organs, training center, exhibition, bid, commercial affairs interchange uses.Thereby, have good value for applications.
