Description

The infrared ray multi-purpose remote controller

A kind of infrared ray multi-purpose remote controller relates to the dispensing device of infrared signal.

Household electrical appliance progressively develop to the drone version direction at present, tend to have plural drone version household electrical appliances in general family, and every kind of household electrical appliance all have a telepilot.Often to seek telepilot when therefore using, thereby produce inconvenience.And those dedicated remote controls all can not get sufficient utilization on function.

The purpose of this utility model provides a kind of infrared ray multi-purpose remote controller, and it is applicable to the infra-red remote control of multiple household electrical appliance.

Adopt such technical scheme according to above-mentioned purpose the utility model: this telepilot comprises infrared transmitting tube, keyboard, be characterized in also comprising a single-chip microcomputer according to the exportable multiple waveform of keyboard instruction, and keyboard ordinate and horizontal line all link to each other with single-chip microcomputer scanning mouth, the single-chip microcomputer signal output joins with infrared emission tube, thereby becomes infrared to go out conversion of signals.There is the coding of various brand electrical equipment single-chip microcomputer inside, needs only the numbering of keying in institute's desire control apparatus from keyboard during use, can carry out control operation.

The utility model integrates the remote control of various household electrical appliances, can carry out infra-red remote control to multiple household electrical appliance, and static power consumptive province, easy to use, advantage that reliability is high are arranged.

The particular circuit configurations of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is according to the infrared ray multi-purpose remote controller circuit theory diagrams that the utility model proposes.

Fig. 2 is according to the infrared ray multi-purpose remote controller software main flow chart that the utility model proposes.

Fig. 3 is according to the infrared ray multi-purpose remote controller software sub-process figure that the utility model proposes.

Below in conjunction with the details of accompanying drawing detailed description according to the concrete device that the utility model proposes.

As shown in Figure 1, the core parts of this telepilot are one can export the single-chip microcomputer of multiple waveform according to keyboard instruction, and its model is KS57C2618.The Xin of single-chip microcomputer and Xout termination crystal oscillator CRYSTAl, the crystal oscillator two ends are connected to capacitor C 1 and C2 respectively, and C1, the C2 other end back ground connection that links to each other.Power supply (battery) is divided into three tunnel, one tunnel vdd terminal that connects single-chip microcomputer behind diode D3, connect the RESET end of single-chip microcomputer behind one road connecting resistance R11, also have one the tunnel behind filter capacitor C4 ground connection.Be connected on single-chip microcomputer RESET end with between the ground after resistance R 10 and capacitor C 3 are in parallel, form electrify restoration circuit single-chip microcomputer P0.0～P0.3 and P0.8 end meets diode D3 respectively behind resistance R 1～R5 negative electrode.Simultaneously, the keyboard ordinate connects single-chip microcomputer P0.0～P0.3 and P0.6 end respectively, and the keyboard horizontal line then connects the P4.0～P4.3 and the P5.0～P5.2 end of single-chip microcomputer respectively.P6.0, P0.0～P0.3, P4.0～P4.3, P5.0～P5.2 be as keyboard scan, reading command.

The signal output part P2.1 of single-chip microcomputer meets infrared transmitting tube D2 after resistance R 6, the infrared transmitting tube other end then connects the anode of filter capacitor C4 after resistance R 9.In order to have bigger emissive power, between resistance R 8 is with infrared transmitting tube, preferably meet the triode Q1 of amplifying signal effect together.And 01 base stage meets R6, grounded emitter, and collector meets infrared transmitting tube D2.Resistance R 8 then is connected across the Q1 base stage with between capacitor C 4 positive poles.In order to indicate the residing state of telepilot, this telepilot also is equipped with light emitting diode D1.And the P2.0 of single-chip microcomputer end connects the anode of filter capacitor C4 after light emitting diode D1 and resistance R 7.

Referring to Fig. 2, at first the single-chip microcomputer electrification reset begins again, carries out RAM initialization and port initialization then.After above-mentioned work was finished, the wait button was pressed, and was that the DEVICE key then returns behind the input equipment coding as if what press; If that press is not equipment key DEVICE, return after then getting key.

The code search sub-process is seen Fig. 3, at first judges whether the search coding after the beginning, does not search for then and returns; At first judge whether TV (TV) coding when searching for, be then to arrive the TV page, and obtain device coding.Same if not the TV coding then judges whether video recorder VCR coding, if then go the VCR page to get device coding then; If not the VCR coding then removes the air-conditioning control AIR-CON page, get device coding then.Obtaining judging whether the key by ENTER behind the device coding, not by then returning, is then to find to deposit sign indicating number behind the coding and return.
