The utility model comprises a sender, a receiver; the sender is arranged in a cover, a power supply indicator, a power supply switch, a laser ferula light hole are arranged on the cover; the panel is provided with a plurality of functional keys; the sender uses a single chip machine as the signal processing circuit, and the laser ferula is embedded in the sender, the laser ferula is of a 300-350MHz sending frequency; the receiver is provided with an interface circuit to computer, the input terminals of the interface circuit are connected with the digital rectifying circuit, the output terminals of the interface circuit are connected with the RS232 or USB. The remote controller can be used to control a computer in the environment without the limitation of the computer wires.

Description

The wireless computer telepilot

Technical field

The utility model relates to a kind of wireless computer telepilot.

Background technology

More in the market employing infrared ray computer telepilot, because its transmission mode has determined short, the high directivity of this UltraVNC effective working distance when work, if hamper is arranged before the receiver, then very easily be interfered, the work effect that causes receiving and sending is had a greatly reduced quality; Also has a kind of wireless mouse that can remote-control computer, no matter desktop type still is the wireless signal that hand-held can only transmit the own functions of mouse such as mouse moving, right and left key, remote control distance is short, poor anti jamming capability, and the user can not arbitraryly operate computing machine.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of based on radiotelegraphy, with laser pointer function and telepilot wireless computer telepilot integrated and convenient to use.

The technical scheme that the utility model adopted is: the utility model comprises transmitter and receiver, the circuit of described transmitter is contained in the housing, use single-chip microcomputer as signal processing circuit in the circuit of described transmitter, built-in laser pointer in the described transmitter, the switch of described laser pointer connects power supply, on the described transmitter housing power light is arranged, power switch, the laser pointer unthreaded hole, the switch of described laser pointer, a plurality of self-defining keys, page turning key, left button, right button, the mouse button of indication four direction, push button signalling on the described transmitter housing except that the switch of laser pointer inserts described single-chip microcomputer, described single-chip microcomputer output termination high frequency generation circuit; The high-frequency digital signal that the receiver receiving antenna is accepted is input to superheterodyne detection and receives amplifying circuit, described superheterodyne detection receives the input end of the output termination numeral shaping circuit of amplifying circuit, the input end of the output termination computer interface circuits of described digital shaping circuit, the output terminal of described computer interface circuits is connected with computing machine RS232 mouth or USB mouth.

Described transmitter frequency of operation is in 300MHz～350MHz frequency range.

Described single-chip microcomputer is AT89C2051.

The beneficial effects of the utility model are: transmitter of the present utility model and receiver have adopted radiotelegraphy, laser pointer function and telepilot is integrated, so it is strong, comprehensive that remote signal penetrates the obstacle ability, the reliable about 10m of remote control radius, need not to aim at receiver, can directly impart knowledge to students or business presentations in the face of the demo content cooperation laser pointer of projector.

Embodiment

Be described further below in conjunction with accompanying drawing.

Transmitter 1: as seen from Figure 1, have on transmitter 1 housing outside power light 11, power switch 18, the laser pointer unthreaded hole 19, also have the switch k15, right button 15, left button 16 of a plurality of self-defining keys 12, page turning key 13, laser pointer 2, the mouse button 17 of indication four direction on the panel, finish the function of mouse and multiple keyboard hot key.

By Fig. 2, Fig. 3 as seen, transmitter circuit is to have replaced original signal processing circuit with single-chip microcomputer 3 in existing disclosed transmitter circuit, single-chip microcomputer 3 selects the AT89C2051 model, the signal of transmitter 1 button is directly sent into single-chip microcomputer 3, such as a plurality of self-defining keys 12 (1., 2., 3., 4., 5., 6.), page turning key 13 (down, on), right button 15, left button 16, (the left side of the mouse button 17 of indication four direction, down, right, on) leg (P37 that can corresponding single-chip microcomputer 3, P35, P34, P33, P32, RXD, P10, P11, P12, P13, P14, P15, P16, P17); The digital signal that produces in the single-chip microcomputer 3 is sent into the N end of high frequency transmission circuit 4, launches by antenna TN behind the carrier wave, and emissive power 2mW, the transmitter frequency of operation is at 300MHz～350MHz; Operating voltage 4.5V; Built-in laser pointer 2 in the transmitter 1, laser pointer 2 links to each other with power supply by light pen switch k15 button, combines with transmitter line.

Receiver: as seen by Fig. 4, Fig. 5, the acceptor circuit received signal, after receiving amplifying circuit 5, superheterodyne detection outputs to digital shaping circuit 7 (being the input pin that the collector of triode T2 meets double operational LM358), the input end (as the T2in pin of chip U2) of the output termination computer interface circuits 6 of numeral shaping circuit 7, the output terminal of computer interface circuits 6 is connected with computing machine RS232 mouth or USB mouth, thereby communicates with computing machine.

During operation, need not to aim at receiver, can directly impart knowledge to students or business presentations the reliable about 10M of remote control radius in the face of the demo content cooperation laser pointer of projector.
