When the switch on wall (input block) pressed away from intelligent electrical controller, make a response after the microprocessor perception, be that switch power load signal is just exported set of pulses coded signal to driver element, relay drive unit sends the switching of pulse control signal control magnetic latching relay contact to magnetic latching relay; Be that light modulation or speed-regulating signal are just exported one group of PWM (width modulation) signal to driver element, be modulated on the photoelectrical coupler again after strengthening driving force, control the silicon controlled conducting by the photoelectrical coupler of zero passage detection, regulate the brightness of power load incandescent lamp or the speed of motor by the controllable silicon output unit.Communication interface receives the data command bag that other peripheral control unit (computer or wireless channel) comes, enter into microprocessor by having the high-transmission data rate and can isolating external high-tension photoelectrical coupler, microprocessor is made a response in the microsecond level and is controlled the action of output unit.Power failure detecting unit connects civil power, when civil power cuts off the power supply, sends the signal of preserving control data to microprocessor; When energy-storage units cuts off the power supply when civil power, provide microprocessor to preserve the temporary required electric energy of control data, treat that microprocessor when power on next time reads out data the state that recovers before the intelligent electrical controller power down.
To intelligent electrical controller embodiment of the present invention shown in Figure 13, the 485 netting twine double nip J5 and the J6 (as shown in figure 10) that have in the intelligent electrical controller and connect, such double nip one-in-and-one-out are convenient to each controller communication unit circuit serial connection at Fig. 2.The current supply circuit of communication unit low voltage component is that diode and voltage stabilizing IC 78L05 by anti-reverse electric current provides by netting twine in controller, and D13 among Figure 10 and U10 are respectively diode and voltage stabilizing IC.
For lamp dimmer, Fig. 2 is the circuit diagram of microprocessor unit circuit.Wherein U3 (STC89C54RD+) is a microprocessor, it is by 5,6,7 pins and 485 communication interfaces and the coupling of the photoelectricity in photoelectricity isolated location circuit IC U5 thereof shown in Figure 7, U6 is connected with U11, baud rate with 9600 is carried out serial communication, the director data bag that analysis, execution and feedback receive to 485 communication IC U1.The signal that microprocessor U3 sends here on can the perception switch on wall, for example 1 pin of the external connection terminal J6 among the input pin 22 of the photoelectricity among Fig. 3 coupling IC U12 and Fig. 6 links to each other, if external reset switch is performed by next time, the 1st pin level of photoelectricity coupling IC U12 is just dragged down once among Fig. 3 so, the 40th pin level of just linking on the microprocessor U3 once changes, promptly once return high variation from high to low, after microprocessor U3 perceives current variation, just give the assembled pulse of corresponding mouthful of line the 18th pin and the 19th pin output 100mS width, this is added on the 3rd and the 7th pin of the coding drive IC U7 (BL8023) among Fig. 8 the 16th pin of assembled pulse by photoelectricity coupling IC U2 and U14 (Fig. 4 and shown in Figure 5).U7 is according to the assembled pulse on the 3rd and the 7th pin like this, output corresponding driving pulse current on the 1st pin and the 5th pin, make the magnetic latching relay K5 among Fig. 9 change a next state, be that the magnetic latching relay output contact is originally the just closed now of disconnection, or be originally that the present of closure just disconnects (hypothesis is originally disconnection) here, after the pulse of microprocessor U3 output, coding drive IC U7 (Fig. 8) also just ignores other various forms of disturbing pulses. and the sequential of microprocessor U3 coded pulse and the width of pulse are specific, and the disturbing pulse coding drive IC U7 that does not meet its feature can not comprehend.The state of keeping this closure that magnetic latching relay just continues, magnetic latching relay K5 at this moment no longer needs electric current.Because the 1st pin of coding drive IC U7 and the output of the 5th pin is high impedance, the coil of magnetic latching relay K5 also just can not get electric current, and its output contact is that the permanent magnet of inner portion stablize adhesive and closure.If K5 is non-magnetic latching relay, circuit is prominent is so disturbed or power down suddenly, and the coil current of K5 will be unstable, cause output contact to touch work, be connected on the output contact electrical appliance for example bulb will frenziedly glimmer, cause user's uneasiness, sometimes even burn electrical appliance.When having damaged the micro computer process chip if the circuit of control section meets with powerful lightning induction, the thunderbolt power failure that usually invariably accompanies again simultaneously, when restoring electricity once more, controller has just lost memory, non-magnetic latching relay will make the electrical appliance that is connected to output contact stop using, and magnetic latching relay just can not lose memory, and it has remembered that firmly you by this order of crossing a switch, make the electrical appliance that is connected on the output contact be continued normal use.This self-sustaining function is that traditional controller can't be accomplished.Have circuit structure and magnetic latching relay that the curtain controller of self-retaining function also can be above-mentioned.
In Fig. 2, U20 that is connected with microprocessor U3 and U21 are the chip for driving of controllable silicon output unit, drive the controllable silicon output unit by optocoupler, can carry out light modulation or speed governing, as the brightness of adjusting incandescent lamp or the speed of electrical equipment motor.
As shown in figure 11, the present embodiment low-tension supply comprises rectification circuit and mu balanced circuit, civil power through after the step-down again after rectification and mu balanced circuit voltage stabilizing to the power supply of the low voltage component of intelligent electrical controller.
As shown in figure 12, the alternating current of 220V is by junction block J1, and the secondary coil PortC of common mode choke coil CT2 and transformer T2---PortD is added on the input end of the photoelectricity coupling IC U16 of Figure 13 and U18.Common mode choke coil CT2 plays filtering, because the electromagnetic interference (EMI) that the output contact of relay has arc spark to produce when switch load is extraneous by the current supply circuit interference of itself, and 485 communication loop is vulnerable to disturb most.In order to reduce voltage and to keep enough little volume, the secondary coil of transformer T2 is done to such an extent that coil turn is many and the line footpath is little, the shaping sample circuit shaping that the alternating current of 220V also keeps the sinusoidal ac signal of a 50Hz to give the back after secondary coil obtains enough step-downs, sampling.U16 among Figure 13 and U18 form the shaping sample circuit, output terminal the 4th pin of U16 and U18 combines, promptly the positive half cycle of alternating current and negative half period are pooled together the 8th pin that is given to microprocessor U3 (STC89C54RD+) among Fig. 2, this pin is an interrupt pin, as the failure detection signal end.If microprocessor U3 is in the alternating current of 50Hz, can not find the waveform (the process shaping is negative saltus step pulse one by one) that exchanges pulsation in the one-period of T=20mS and just think power down or power failure, microprocessor U3 just is saved in the dimming state data of current light adjusting controller in the inner electrically-erasable memory, treats when power on next time data are read out the state that recovers before the power down.The time that this storing process needs only needs the time about 2mS, and microprocessor is stored the required electric energy of data and provided by the tank circuit that diode Dx and capacitor C x are formed after power down.
