The utility model has the advantages of strength electricity isolation, large receiving angle and free selection of manual operation and remote control.

Description

The multichannel infrared remote control switch

The utility model relates to a kind of multichannel infrared remote control switch that is used for household electrical appliance such as pendent lamp, pinup, floor-lamp, ventilating fan, fan, TV, sound equipment and industry, commercial various electrical equipment.

Existing remote control switch adopts the capacitance decompression method, capacitor is fragile, hot base plate forceful electric power, light current is not every the merchant, the infrared emission receiving angle is little, easily aging, when adopting remote control, manual control is not set, even also just one tunnel manual control of manual control is arranged, thereby do not satisfy daily family expenses and industry, commercial needs.

The utility model and purpose are in order to overcome the shortcoming of prior art, a kind of infrared emission to be provided, and receiving angle is big, can the multichannel remote control and the multichannel infrared remote control switch of multichannel manual control.

The technical solution of the utility model is that it is made up of radiating circuit, receiving circuit and control circuit, radiating circuit is by the coding integrated circuit, infrared emission circuit and infrared transmitting tube are formed, be connected with the coding integrated circuit by a plurality of digital control keys, the encoded integrated circuit coding of digital control keyed jointing messenger latchs, discerns the back and exports by the clock coded pulse, amplify through shaping, be modulated at the infrared transmitting tube emission; Receiving circuit and control circuit are made up of infrared remote receiver, decoding circuit, triggering memory circuit, execution change-over circuit, power unit, infrared remote receiver receives the modulation signals that reflector is sent here, again through shaping amplification, decoding circuit decoding, gating corresponding one tunnel, trigger memory circuit, through power driving circuit, drive that road relay adhesive that is connected to controlled electric appliance accordingly again.A remote manual control conversion master switch and a plurality of remote manual control change over switch are housed in carrying out change-over circuit.

Embodiment of the present utility model is described further in conjunction with the accompanying drawings.

Fig. 4 is multichannel infrared remote control switch receiving circuit and control circuit schematic diagram

By Fig. 3, shown in 4, present embodiment is one 4 road infrared remote control switch, it is made up of reflector and receiving unit, transmitter section is divided into a radiating circuit, by radiating circuit shown in Figure 3 by coding integrated circuit (IC) 1, infrared emission circuit V1, V2 and infrared transmitting tube ILED form, by AN1～AN88 digital operating key, just enough these digital control keys are connected with IC1 respectively only to need 4 in the present embodiment, are provided with automatic circuit break function for saving power supply IC1, LED is the output state indication, when pressing numerical key AN, the IC1 coding latchs, through the identification of IC1 error detection, press clock coded pulse output, through V1, the V2 shaping is amplified, and is modulated at the ILED emission.By shown in Figure 4, receiving circuit and control circuit are by infrared remote receiver IC2, decoding circuit IC3, trigger memory circuit IC4, carry out change-over circuit and power unit composition, IC2 receives the modulation signals that reflector is sent here, amplify through the VT1 shaping, decode through IC3, gating corresponding one tunnel is as CP1, and this moment, CP1 was that high potential triggers IC4, and the Q+D end of IC4 becomes high potential by electronegative potential makes the VT2 conducting, relay J 1 adhesive, thereby the connection load appliance, when not receiving second pulse signal, state keeps always.

Transmitter portion is remote-controlled 8 the tunnel in the present embodiment, and receiver remote-controlled be 4 the tunnel, extendible as required.In the executive circuit, K is the master switch that remote manual control is switched, and the remote manual control for four tunnel switches respectively and switched by K1, K2, K3, K4.The layout of these switches as shown in Figures 1 and 2, Fig. 1 is the utility model receiving unit structural representation, 1 is big liner plate, 2 is the remote control switch panel, 3 for receiving head, 4 is the upright switches of 5 parallel, is equipped with the wiring board 5 of reception at the switch bosom.

Adopt such structure and circuit, forceful electric power light current is isolated, infrared emission, receiving angle are big, can arbitrarily angled remote control in 25～30 square metres of areas, and switch has adopted multichannel remote control mode and manual mode to select, and the user can select to use.
