The utility model is compared with traditional Infrared remote controller, has following effect:

(1) user can control light fixture fully with remote controller, comprises that open and close, third gear time-delay, the Night of light fixture switches;

(2) user can control light fixture with soft-touch control; The touch switch can carry out ON operation to a road lighting lantern of wherein appointment, also can carry out the operation of Close All and releasing Night to all road lighting lanterns.

Description of drawings:

Fig. 1 is the transmitter circuit schematic diagram of light fixture infrared remote controller described in the utility model.

Fig. 2 is the acceptor circuit schematic diagram of light fixture infrared remote controller described in the utility model.

Below in conjunction with accompanying drawing operation principle of the present utility model is described in detail as follows:

1. reflector operation principle:

Radiating circuit as shown in Figure 1, BA5104 is the New-type CMOS coding chip that is used for infra-red remote control, K1-K6 is an input, when pressing the K1-K6 key, (12) (13) internal clock circuit that pin connect and external 455KHZ crystal oscillator by BA5104, C1, the oscillating circuit starting of oscillation work that C2 forms, produce the 38KHZ CF signal through the inner shaping frequency division of circuit, the data of K1-K6 input are encoded, by (15) pin D0 end serial output, amplify the rear drive infrared transmitting tube through triode Q1 and send the modulating wave infrared pulse signal, (14) pin is that emission state shows output, and LED1 was bright when infrared signal output was arranged, otherwise did not work.

2. reception operation principle:

Receiving circuit as shown in Figure 2, IC2 is the infrared reception/demodulation module of microminiature, this component size is little, have the daylight filtering function, the built-in magnetic screen, quiescent current is little, use this element, increased antijamming capability, preposition amplification, carrier wave frequency-selecting, the pulse modulation finished by it.When infrared pulse signal arrived, the IC2 output low level after Q1 is anti-phase, exported the external interrupt mouth P3.2 of single chip circuit IC1 to, through the IC1 decoding, judged, by the P1 mouth output control signal corresponding of IC1.The drive current of P1 mouth is 20mA, and through R7 and LED2, R8 and LED1 directly drive bidirectional triode thyristor T1 and T2.LED1 and LED2 are the status indicator lamps of output, and LED5 is bright to be time-delay indication in 0.5 hour, LED5,4 bright be time-delay indication in 1 hour, LED5,4,3 bright be time-delay indication in 1.5 hours, LED4 is glittering to be the Night indication, C1, R2 forms power-on reset circuit, (4) (5) internal clock circuit that pin connect and the external 6M crystal of IC1, C2, C3 forms oscillating circuit.Q2, R8 form soft-touch control, and R1 is a current-limiting resistance, when human body touch during to sheet metal M1 the Q2 collector electrode be low level, affact the external interrupt mouth P3.3 of IC1 through R1, IC1 goes shake, time-delay back negate P1.3.

Circuitry adopts the capacitance decompression mode to power, and guarantees the reliability of long-time power supply, because do not use transformer, there is not problems of excessive heat in circuit, and power consumption has also reduced a lot.Civil power is through capacitor C 4 step-down D6, D7 rectification, voltage stabilizing, and C5 filtering obtains the DC power supply about 8V, after three terminal regulator U1 voltage stabilizing, obtaining more stable 5V voltage, use for complete machine, because this circuit is directly controlled the 220V civil power, so should take care during installation.

Function declaration: (P1 mouth low level is effective)

When pressing reflector K1 key, P1.2 and the P1.3 of IC1 are low level, T1, T2 conducting.

When pressing reflector K2 key, the P1 mouth of IC1 all is high level, closes All Jobs, removes memory internal.

When pressing reflector K3 key, the P1.2 mouth negate of IC1, (uprising step-down when high when hanging down) T2 changes thereupon.

When pressing reflector K4 key, the P1.3 mouth negate of IC1, (uprising step-down when high when hanging down) T1 changes thereupon.

Press reflector K5 key the 1st time, the P1.5 mouth of IC1 is low level, and LED5 is bright, expression time-delay 0.5 hour.

Press reflector K5 key the 2nd time, the P1.5 of IC1,6 mouthfuls are low level, LED5,4 bright, expression time-delay 1 hour.

Press reflector K5 key the 3rd time, the P1.5 of IC1,6,7 mouthfuls are low level, LED5,4,3 bright, expression time-delay 1.5 hours.

Press reflector K5 key the 4th, the P1.5 of IC1,6,7, mouth are high level, and LED5,4,3 goes out, and expression stops time-delay.

When pressing reflector K6 key, the P1.6 mouth level of IC1 height alternate, LED4 flashes, and the expression receiver enters Night, presses the K1-K5 key, is the P1.3 port of negate IC1 entirely, and T1 changes thereupon, and has cancelled delay function.Press reflector K6 key again, the P1.6 mouth is high level, and LED4 goes out, and the cancellation Night recovers original function.

Touch sheet metal M1, when the port P1 of IC1 all was high potential, the P1.3 mouth was low level, the bright T1 conducting of LED2.

Touch sheet metal M1, when the port P1 of IC1 had a mouth to be low level, set port P1 removed all memories.

This shows, the decoding infrared ray system that forms by single-chip microcomputer be suitable flexibly.The particularly important is, increase and modify feature needn't be changed hardware sometimes, directly just can be finished by software, and this is that other remote control system can not be compared.
