Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of the utility model Intelligent Home Appliance Controller output control circuit.
Embodiment
As shown in Figure 1: the utility model Intelligent Home Appliance Controller output control circuit, comprise three on-off circuits, each on-off circuit is identical, wherein, first on-off circuit comprises photoelectrical coupler T1, controllable silicon S1, rectifier bridge D1, passive solid relay F1, the first resistance R11, the second resistance R12; Second on-off circuit comprises photoelectrical coupler T2, controllable silicon S2, rectifier bridge D2, passive solid relay F2, the first resistance R21, the second resistance R22; 3rd on-off circuit comprises photoelectrical coupler T3, controllable silicon S3, rectifier bridge D3, passive solid relay F3, the first resistance R31, the second resistance R32; First pin of described photoelectrical coupler T1 is connected with power supply VCC, second pin of photoelectrical coupler T1 is connected with the I/O mouth of single-chip microcomputer, the three-prong of photoelectrical coupler T1 is connected with the negative electrode of controllable silicon S1, and the 4th pin of photoelectrical coupler T1 is connected with one end of the first resistance R11, one end of the second resistance R12 respectively; The other end of the first resistance R11 is connected with the anode of controllable silicon S1, and the other end of the second resistance R12 is connected with the control pole of controllable silicon S1; Controllable silicon S1 and rectifier bridge D1 is in parallel, and the input end of rectifier bridge D1 is connected with power supply 220V, and the output terminal of rectifier bridge D1 is connected with one end of passive solid relay F1, and the other end of passive solid relay F1 is connected with the output terminal of intelligent appliance; The connected mode of second on-off circuit, the 3rd on-off circuit is identical with the connected mode of first on-off circuit; Described photoelectrical coupler all adopts PC817 photoelectrical coupler, and described controllable silicon all adopts S6010L controlled silicon chip, and described passive solid relay F1 adopts JFW type passive solid relay.
Whether the control signal that the utility model Intelligent Home Appliance Controller output control circuit is carried by single-chip processor i/o mouth controls corresponding photoelectrical coupler luminescence, after light-to-current inversion, whether controls silicon controlled switch, thus realizes Phototube Coupling; When photoelectrical coupler is luminous, controllable silicon turns off, and intelligent appliance quits work; When photoelectrical coupler is not luminous, controlled silicon conducting, intelligent appliance is started working; After the control signal of single-chip processor i/o mouth conveying disappears, controllable silicon turns off at the zero crossing of alternating current, thus the spark produced when avoiding common relay switch and the interference to power supply, make Intelligent Home Appliance Controller output control circuit have better reliability, security, add the serviceable life of whole intelligent appliance system; When intelligent appliance system is out of order, photoelectrical coupler is owing to can not get electric energy and not luminous, and after intelligent appliance switches on power, controlled silicon conducting, ensures that all intelligent appliances can normally work.
