Description

The multifunctional microcomputer telepilot that infrared ray and radio remote controller are two-in-one

The utility model relates to control the telepilot of various items, but refer to especially a kind of with a telepilot just transmitting radio or ultrared signal so that the infrared ray and the two-in-one multifunctional microcomputer telepilot of radio remote controller of control various items.

In the known telepilot, be that the integrated circuit by the center is constituted with CPU by one group, this CPU has input and sets controlling signal, the output controlling signal, and the function of computing, processing, storage signal arranged, and the signal of setting can be given coded memory it, the power supply transmission frequency has several wave bands to select, and is mainly in the mode of radio as the control of news source.

Again, if action with simple radiowave gauge tap, though it is simple, fault is few, and easy operating, but also do not have anti-theft feature, thereby follow-up research and development improvement utilizes pulse-generating circuit to produce pulse signal, can accept aforementioned pulse signal triggers and the coding circuit of generation tandem coded signal, can launch the radiating circuit of aforementioned tandem coded signal, so, then Fa She electric wave is the mode with password, and the receiver of receiving end has also been set the emission electric wave password of accepting transmitting terminal only, the electric wave of other frequency does not have this password, then receiving terminal is failure to actuate, and this is to have a design of antitheft effect, the central controlled lock of using as automobile etc.

Again, the mode with infrared ray transmission signal is used for electrical home appliances mostly, precisely because generally be all miniwatt, distance can not be too far away, and environment also can not have too many thermal source; And ultrared wavelength coverage is narrow, easily causes the difficulty of frequency division, so majority is all done single remote control with infrared ray.

Therefore, up to now, all on the market telepilots all can't can select to launch infra-red signal and radio signals on a body.

The operation of existing telepilot needs exclusive telepilot of each machine collocation, and what have is radio signals, and what have is infra-red signal, and also has the situation of malfunction between identical sometimes type, very is inconvenience.And when using different remote control machine, that telepilot of memory of still needing is to cooperate that machine, obscures very easily.

At the problems referred to above, fundamental purpose of the present utility model is to provide a kind of infrared ray and the two-in-one multifunctional microcomputer telepilot of radio remote controller, be to utilize a telepilot to plan as a whole to control infrared ray news source and the emission of radio source with micro processor, cooperate the collocation of its peripheral auxiliary circuit, overcome above-mentioned difficulties jointly, reach the actual demand of the multiple different remote-control targets of control with minimum cost and minimum volume, the simplest mode, and break through traditional constraint.

The utility model is provided with eight circuit bank basically, has promptly comprised

A) micro processor: in button inputting circuits, push button, just be stored in the circuit, read it, and differentiate the channel that sets at present, again by correct radiating circuit emission by remote control mode.

B) button inputting circuits: comprise five buttons, and have a busbar wire to be connected in micro processor,, produce different remote control modes, indicate different instructions with this and drive it via pressing different key.

C) flashing light control circuit: if select different channels, different flashing light modes is arranged then, showing difference, and whether normal transmission is encoded to judge this telepilot.

D) power circuit: the power supply of the whole group of supply circuit operation.

E) remote control storage circuit: in order to deposit remote control mode and channel setting state.

F) one of superregeneration radio transmitter circuit: in order to launch the superregeneration radio signals of first group of channel.

G) two of the superregeneration radio transmitter circuit: in order to launch the superregeneration radio signal of second group of channel.

H) infrared transmitter: in order to launch the infra-red signal of the 3rd and four group of infrared ray channel.

Above explanation sees also Fig. 1.

Micro processor in the foregoing circuit can be pushed situation according to buttons different in the button inputting circuits, infra-red signal in being stored in the remote control storage circuit or radio signals take out different signals, and then according to user's demand, through radio transmitter circuit transmitting radio signal; Or, make infrared light-emitting diode conducting emission infra-red signal through infrared transmitter triggering and conducting transistor then.

The utility model utilizes the logical circuit in the micro processor and the software design of storage, makes this machine in the collocation state of controlling specific keys, can produce

(a) radiowave of several different channels.

(b) circulating first to fourth channel of selection.

(c) circulating setting automatic or manual channel.

(d) close or open telepilot.

All, can reach above-mentioned multi-functional effect with easy circuit structure.

In sum, the utility model is more and more wide at the scope of telepilot (infrared ray and radio) use in the market, the puzzlement that causes the consumer to use and carry, the spy is integral transmitting set circuit and infrared transmitter circuit design, but can be convenient to the user, so that control various items only with a telepilot just transmitting radio or ultrared signal.
