The output current for taking electric unit 110 is larger, and control unit 130 adjusts the 4th resistance R4To smaller resistance value, so as to battery chip U4It is defeated
Go out larger charging current to charge to battery；Conversely, when bearing power is smaller, energization takes the output current of electric unit 110 smaller,
Control unit 130 adjusts the 4th resistance R4To larger resistance value, so as to battery chip U4The smaller charging current of output charges to battery.
For example, it is assumed that single 100 three road headlamps of control of firewire switch, when opening headlamp all the way, battery chip U4Export charge capacity
Constant current is 40mA, when opening two-way headlamp, battery chip U4Output charging rated current is 60mA, when three road headlamps
When fully open, battery chip U4Output charging rated current is 100mA.
And when the control signal end of control unit 130 exports low level, the silicon-controlled U of optocoupler2Middle bidirectional triode thyristor Q2It closes
It is disconnected, bidirectional triode thyristor Q1It does not trigger, is off state, switch 100 input terminal TP1With output terminal TP2It is separated, load
There is no electric current in main control loop, load is closed.Therefore rectifier diode D1On also no electric current pass through, decompression chip U1Without output,
Charging chip U4Power-off does not work.At this point, battery pack 122 is discharged, to decompression chip U3Power supply, output 3.3V DC voltages for
130 energization work of control unit, at this point, control unit 130 can be operated in low power consumpting state.In this way, the single fire of effective guarantee
Wiretap 100 can be worked normally when loading and opening and closing, and load complete switches off during closing, no security risk.
In addition, control unit 130 further includes AD sample circuits, which is suitable for measuring 122 voltage of battery pack, control
Unit 130 processed can adjust its operating mode according to the voltage measuring value.When measure voltage value be higher than 4.0V when control unit 130 be
Normal mode of operation when measuring voltage value to open low-power consumption mode during 3.5-4.0V, is then adopted when measuring voltage value less than 3.5V
Keystroke pattern is taken, ensures that control unit 130 keeps the working time as sufficient as possible in all cases.
