4resistance, and then select charging current to battery pack 122.Understandably, when bearing power is larger, the output current of energising power taking unit 110 is comparatively large, and control unit 130 regulates the 4th resistance R
4to less resistance, thus battery chip U
4export larger charging current to charge to battery; Otherwise when bearing power is less, the output current of energising power taking unit 110 is less, and control unit 130 regulates the 4th resistance R
4to larger resistance, thus battery chip U
4export less charging current to charge to battery.Such as, suppose that single live wire switch 100 controls three road illuminating lamps, when opening a road illuminating lamp, battery chip U
4exporting charging rated current is 40mA, when opening two-way illuminating lamp, and battery chip U
4exporting charging rated current is 60mA, when three road illuminating lamps are all opened, and battery chip U
4exporting charging rated current is 100mA.
And when the control signal end output low level of control unit 130, optocoupler controllable silicon U
2middle bidirectional triode thyristor Q
2turn off, bidirectional triode thyristor Q
1not triggering, is off state, the input TP of switch 100
1with output TP
2separated, there is no electric current in load main control loop, load close.Therefore rectifier diode D
1on do not have electric current to pass through yet, step-down chip U
1no-output, charging chip U
4power-off does not work.Now, battery pack 122 is discharged, to step-down chip U
3power supply, export 3.3V direct voltage and to be energized work for control unit 130, now, control unit 130 can be operated in low power consumpting state.Like this, the single live wire switch 100 of effective guarantee all can normally work when load opens and closes, and when closing, load turns off, completely without potential safety hazard.
In addition, control unit 130 also comprises AD sample circuit, and this AD sample circuit is suitable for measuring battery pack 122 voltage, and control unit 130 can regulate its mode of operation according to this voltage measuring value.When measuring voltage value is normal mode of operation higher than control unit during 4.0V 130, low-power consumption mode is opened when measuring voltage value is 3.5-4.0V, then take keystroke pattern when measuring voltage value is less than 3.5V, ensure the operating time that control unit 130 keeps sufficient as far as possible in all cases.
