Accompanying drawing explanation
Fig. 1 is the circuit connection diagram of bicycle lock control circuit of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, bicycle lock control circuit of the present utility model, comprise control signal input En for being connected with microprocessor, for control lockset operating state lockset interface J1, optocoupler U1, pipe Q1, biasing circuit, indicator light circuit and diode D1 open the light.
The two ends of the transmitting tube of optocoupler U1 connect respectively connection control signal input En and the first power supply respectively, and described the first power supply refers to the power unit that microprocessor system is driven, and can refer to its positive power source terminal, can be also negative power end or ground connection; Particularly, in the present embodiment, described the first power supply is+5V power supply; The anode of the transmitting tube of optocoupler U1 is by be connected to+5V of resistance R 4 power supply, and the negative electrode of the transmitting tube of optocoupler U1 is connected with control signal input En; Take the low level output of microprocessor as effectively, and the transmitting tube conducting of optocoupler U1 is and luminous, and such mode is effectively pushed the transmitting tube of optocoupler U1.Also can change closure, make the transmitting tube minus earth of optocoupler U1, anode meets control signal input En, by high level, promoted, but on needing mainly the output signal voltage of microprocessor to be carried out, draw, avoid the not high enough transmitting tube luminous signal of optocoupler U1 that makes of voltage of high level weak or unstable.
The anodic bonding of switching tube Q1 is to second source, and the negative electrode of switching tube Q1 is connected to the first end of lockset interface J1, the second end ground connection of lockset interface J1; Described biasing circuit is connected to grid and the second source of the pipe Q1 that opens the light, and biasing circuit is also by the receiving tube ground connection of optocoupler U1.Described second source refers to the power supply that lockset is powered, and the voltage that power to lockset is generally high than the driving voltage of microprocessor, and in the present embodiment, second source is+24V power supply.Particularly, described biasing circuit comprises the first resistance R 1, the second resistance R 2 and the 3rd resistance R 3; Be connected to+24V of the first end of the first resistance R 1 power supply, the second end of the first resistance R 1 is connected to the grid of switching tube by the second resistance R 2; The second end of the first resistance R 1 is connected to the anode of the receiving tube of optocoupler U1, the minus earth of the receiving tube of optocoupler U1 by the 3rd resistance R 3.Transmitting tube conducting as optocoupler U1, when luminous, the also conducting of the receiving tube of optocoupler U1, thereby receiving tube place branch road is switched on, and the grid voltage of the pipe Q1 that opens the light is dragged down, and makes the Ugs of switching tube be greater than its cut-in voltage, switching tube conducting, thereby make one end of lockset interface J1 be+24V power supply, other end ground connection, can form power supply to bicycle lock.Described indicator light circuit comprises light-emitting diode D2; The anode of light-emitting diode D2 is connected to the negative electrode of switching tube by a resistance R 5, the plus earth of light-emitting diode D2, and after the pipe Q1 conducting of opening the light, light-emitting diode D2 also conducting carries out luminously, realizes deixis.The negative electrode of described diode D1 is connected to the negative electrode of switching tube, the plus earth of diode D1.Due to the inductive effect of magnetic key operated lock, when switching tube is turned to while closing by conducting, lockset can produce larger reverse current, if electric current is by switching tube, likely can cause switching tube damage in the other direction; And due to diode D1, reverse current carries out water conservancy diversion by diode D1, avoided reverse current to flow through switching tube, protective efficient switch pipe.Use optocoupler U1, the impact of can isolate+24V power supply on microprocessor portion, safer to weak signal end, control convenient.
