Abstract

A remote-control emitter capable of being in online operation with a computer comprises a single-chip microcomputer, a peripheral circuit thereof and a remote-control signal emitting circuit, wherein the single-chip microcomputer is arranged in a casing, and the remote-control signal emitting circuit is used for emitting wireless remote-control signals to a controlled device under control of the single-chip microcomputer. The remote-control emitter is characterized by further comprising a USB (universal serial bus) interface, a power line of the USB interface is connected with power supplying ends of the single-chip microcomputer and the remote-control signal emitting circuit so as to supply direct-current power for the same, a signal line of the USB interface is connected with an input end of the single-chip microcomputer and used for inputting control commands to the single-chip microcomputer. The remote-control emitter is capable of being in online operation with the computer and has the advantages that firstly, the computer can supply direct-current power source to the remote-control emitter; and secondly, the controlled device can be remotely controlled by the aid of the computer.

Description

A kind of remote control transmitter that can be online with computer

Technical field

The utility model belongs to a kind of electronic-controlled installation, is specifically related to a kind of miniwatt remote control transmitter.

Background technology

The miniwatt remote control transmitter is generally used for wireless industrial electric control, wireless senser, wireless data acquisition system, security warning system, household electrical appliance controlled in wireless, toy, doorbell, garage door, supply socket remote control, automobile, motorcycle anti-theft remote control etc.Mostly existing household appliance remote control transmitter is the telepilot of hand-held mobile, and it can realize the manual control of household electrical appliance, and along with the raising of people's living standard, people wish with more form consumer to be controlled.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of can by computer to power device carry out straighforward operation can be online with computer remote control transmitter.

The technical scheme that addresses the above problem is: the utility model is provided with single-chip microcomputer and the peripheral circuit thereof that is contained in the housing, and

The remote signal radiating circuit is used for sending the wireless remote control signal to controlled device under the control of single-chip microcomputer; It is characterized in that:

Also be provided with USB interface, the power lead of USB interface is connected with the feeder ear of single-chip microcomputer with the remote signal radiating circuit, thinks that it provides direct supply; The signal wire of USB interface is connected with the input end of single-chip microcomputer, is used for to the single-chip microcomputer input control order.

Described controlled device is meant to have the device of accepting the radio remote-controlled signal function, for example can accept the device such as remote circuit socket, switch on wall of wireless remote control signal.

The using method of this device is to be connected with computer by USB interface, then by on-line software at the enterprising line operate of the man-machine interface of computer screen, computerize the single-chip microcomputer sending controling instruction in remote control transmitter, remote control transmitter sends the wireless remote control signal according to the instruction that computer sends to controlled device.

The online use of the utility model and computer, the one, can utilize computer to provide direct supply for remote control transmitter, the 2nd, can carry out straighforward operation to controlled device by computer.

Embodiment (referring to Fig. 2)

This routine telepilot is provided with the HT82M99E-20 single-chip microcomputer that is contained in the housing, and 20,19 pin of single-chip microcomputer are connected with the clock circuit that electric capacity Y2, C15, C16 form.

Control end 11 pin of single-chip microcomputer are connected with the remote signal radiating circuit; The remote signal radiating circuit is made up of triode G1 and peripheral circuit, the Y1 filter capacitor that connects in the base loop can produce the 433.92MHZ carrier frequency, its base stage is connected with single-chip microcomputer output terminal 11 pin, and this remote signal radiating circuit can send carrier wave to controlled device under the control of single-chip microcomputer 11 pin be the wireless signal of 433.92MHZ.

Housing is provided with USB interface, its 1 pin 5V power end is connected with the telepilot feeder ear with 4 pin GND end, be used to single-chip microcomputer and remote signal radiating circuit that 5V is provided direct supply, its

signal wire

2,3 pin are connected with

input end

4,3 pin of single-chip microcomputer respectively, are used for to the single-chip microcomputer input control order.

Single-chip microcomputer 10 pin are connected with+5V power supply by pilot lamp LED and resistance R 10, and when wireless signal transmission was arranged, this pilot lamp was bright, and is synchronous with the emission of signal, is used for launching working properly to user prompt.

This telepilot can be connected with computer by USB interface, after the connection again by on-line software at the enterprising line operate of the man-machine interface of computer screen, by the single-chip microcomputer sending controling instruction of computation to remote control transmitter, remote control transmitter sends remote signal according to the instruction that computer sends to controlled device.

If controlled device need carry out sign indicating number is learnt to this remote control transmitter, can on controlled device, press earlier and receive the study button, pilot lamp can dodge slowly on it, expression enters learning state, in 12 seconds, click the transmission learning key of computer screen man-machine interface then, the coded signal that the wireless signal transmission circuit of this remote control transmitter promptly can be learnt is launched with the wireless carrier signal of 433.92MHZ, controlled device receive rear indicator light by dodge slowly-extinguish-grow bright, the expression learning success, then can be by " ON " on the computer man-machine interface, " OFF ", or " light modulation " key has carried out remote control to controlled device.

Claims

One kind can be online with computer remote control transmitter, be provided with the single-chip microcomputer and the peripheral circuit thereof that are contained in the housing, and

The remote signal radiating circuit is used for sending the wireless remote control signal to controlled device under the control of single-chip microcomputer; It is characterized in that:

Also be provided with USB interface, the power lead of USB interface is connected with the feeder ear of single-chip microcomputer with the remote signal radiating circuit, thinks that it provides direct supply; The signal wire of USB interface is connected with the input end of single-chip microcomputer, is used for to the single-chip microcomputer input control order.
