4, maintain power supply and cut off the testing process of the testing circuit of power supply:

Maintaining power supply and cutting off power supply is the working current of detection load.

When selecting without lotus power down function, bearing power is less than in the situation of 0.1W, and its electric current is in microampere order.Owing to detecting shunt, be the 5th diode D5 by two shunting actions that have been in series, the 6th diode D6 forms, its impedance is two knot electric fields, about 1.4V, with the 5th diode D5, in blockade the 2nd triode BG2 input circuit that the 6th diode D6 is in parallel, only has an emitter junction electric field, about 0.7V, resulting impedance is less than shunt resulting impedance, when load current is very little, make the i.e. pressure drop of the 12nd resistance R 12 of base resistance of the 2nd triode BG2 be less than 0.7V, electric current all flows to the input circuit of the 2nd triode BG2, the 2nd triode BG2 saturation conduction blocks the charging circuit of capacitor C 3.When the continuous increase of load, working current also increase thereupon, voltage drop in the 12nd resistance R 12 is risen thereupon, when being raised to 0.7V and have over trend, the 5th diode D5, the 6th diode D6 conducting, under the characteristic of diode forward constant voltage, the base voltage of the 2nd triode BG2 is by constant, and later increased electric current is shunted by the 5th diode D5, the 6th diode D6.When selecting little load power down function, because the 2nd triode BG2 is operated in amplification region, load power significantly changes and causes the variation thereupon of working current, causes the height that is blocked voltage to follow variation, select suitable working point, just can select to maintain the minimum power of power supply.

Due to line voltage in different regions, Various Seasonal, the fluctuation of different period be very large, in the situation that voltage is very low, may cause in the 8th resistance R 8 dividing potential drop too low, makes the present invention can not normal power down.When voltage becomes suddenly very high, because charging current changes by exponential law, initial velocity is very fast, and load current changes by direct proportion, and the potential dividing potential drop in the 8th resistance R 8 also rises very highly, and blockade may be overturned, cause load at work because of malfunction power-off midway.Therefore in circuit, added the mu balanced circuit being formed by the 3rd stabilivolt D3.The course of work is: with the 3rd stabilivolt D3, the 8th resistance R the 8, the 9th resistance R 9 is stabilized in working range to when the 8th resistance R 8, the 9th resistance R 9 dividing potential drop enough voltage storage level, has normal work dividing potential drop when guaranteeing that line voltage is very low in the 8th resistance R 8.When line voltage rises very highly, because the charging voltage in the 3rd capacitor C 3 is held, and load current increases in proportion, the 2nd triode BG2 the 2nd triode BG2 conducting amount that makes to block strengthens, the collector voltage of its 2nd triode BG2 declines and causes the voltage follow of the 3rd capacitor C 3 to decline, form like this negative-feedback circuit, guaranteed reliably the steady operation of circuit.Because the 3rd stabilivolt D3 offset of sinusoidal ripple is cut top effect, in order to improve effective charging voltage, a 4th capacitor C4 in parallel on the 3rd stabilivolt D3, power supply is filtered into direct current, to improve charge efficiency, after mu balanced circuit access, can be adapted to voltage in the variation range of 100V-270V.

5, the 1st triode BG1 is the output phase-reversing tube of infrared remote control receiver IRM, due to infrared remote control receiver IRM output be negative pulse, and the 1st thyristor BT1 to trigger what need be positive pulse, so must paraphase.

The course of work is: infrared remote control receiver IRM is when static state, be output as high level, its numerical value approaches supply voltage, make the 1st triode BG1(PNP type) base stage and emitter equipotential and in zero state partially, the 1st triode BG1 cut-off, the 1st thyristor BT1 blocking-up, motor D does not work.When infrared remote control receiver IRM receives after signal, infrared remote control receiver IRM exports negative pulse, amplitude is several volts at zero point, the emitter current potential of the 1st triode BG1 forms base flow higher than base potential, the 1st triode BG1 conducting, the collector current after amplification is by the 4th resistance R 4, for the control utmost point of the 1st thyristor BT1 provides gate current, the 1st triode BG1 conducting, motor D obtains voltage and drives the 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 to close cutter power supply.

Due to circuit triggers is a simple DC channel, the requirement of not free and electrical angle, more, without reading out data, therefore, utilize its carrier wave to trigger, carrier widths far surpasses the sincere firmly time of thyristor, conducting reliably, so can, by the remote control transmitter of household electrical appliances self, press any one function key and can trigger, because the remote control transmitter of general household electrical appliances can be received work, so do not need to join dedicated transmitter.

The 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 drop into after powered operation, and limit switch XK cuts out circuit to avoid unnecessary consumption by battery E.Distant control function is mainly used in watching TV, particularly before and after sleep, watches, and start, shutdown reach Full remote controlled, use ten parts of convenience.Computer, owing to operating before screen, without using remote control, therefore can disconnect remote-controlled power switch 12, to reduce the static power consumption of Receiver, makes the present invention become zero consumption standby completely, adopts pushbutton switch 13 starts during work.

After load place in circuit, if during 1 selection idling lotus power down function, maintain for power detection circuit and will detect its internal resistance, make battery E by battery control circuit automatically for mechanical actuating mechanism provides a power supply, motor D outputting power promotes the 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 for load power supply.After load operation, thereby its working current is turned off testing circuit, detect blockade shutoff testing circuit, maintain the power supply to load.While 2, selecting little load power down function, after pushbutton switch 13 or infra-red remote control start, load operation electric current is detected equally and maintain power supply.When outer load is cut off or uses power to be significantly reduced to setting value, breaking circuit block to be removed, and control circuit provides an of short duration reverse voltage for motor, and motor is just exported an of short duration reverse power, promotes knife-like switch by dump.

No-load consumption during for fear of self standby of the present invention and being struck by lightning, thereby the present invention be take battery and is thoroughly departed from electrical network as power supply, because thyristor does not have electric current to flow through when blocking, only need add a voltage, so the present invention's power consumption when standby is zero.Motor D is in when work, due to time compole short, electric current is little, battery E discharge rate is very low.Battery E once can be used long time, with average every day of ten starts, calculates, and motor D work T.T. less than ten seconds, electric current is: 80-100mA, year power consumption is less than 100mAh, and the capacity of No. 7 dry cells is generally more than 400 mAh.If connect infrared remote control receiver IRM, the present invention just has the static consumption of less standby.
