(embodiment)
Below, with reference to description of drawings the 1st embodiment of the present invention.
Fig. 1 is the 1st embodiment's a circuit diagram.
Fig. 2 is the 1st embodiment's a time diagram.
Fig. 3 is the 2nd embodiment's a circuit diagram.
Fig. 4 is the 3rd embodiment's a circuit diagram.
Fig. 1 is the automobile-used engine ignitor of two-wheel, this engine ignitor by battery 1 with 12V terminal voltage, utilize ignition switch 2 that ignition key opens and closes, use the spark plug 5 of igniting unit 3, spark coil 4 and the motor of microprocessor to constitute.
The negative terminal of battery 1 is connected ground connection with car body, and anode is connected with ignition switch 2 by safety fuse cutout 6.Closed between a point and b point when ignition switch 2 disconnects, simultaneously, c point and d point are separated, and a point and b point were separated when ignition switch 2 was connected, and be simultaneously, closed between c point and d point.
The control device 7 of igniting unit 3 has power supply terminal 8, igniting enabling signal terminal 9 and trigger terminal 10.Capacitor C1 is connected between e point and the f point, and resistance R 1 is connected between f point and the g point, and the f point is connected with the power supply terminal 8 of control device 7.Zener diode ZD1, resistance R 2, resistance R 3 are connected in series between e point and the g point.The base stage of transistor T R is connected between resistance R 2 and the resistance R 3, and collector electrode is connected with the igniting enabling signal terminal 9 of resistance R 4 and control device 7, and emitter is connected with the g point.
Spark coil 4 has primary air 12 that is connected with high voltage circuit 11 by capacitor C2 and the secondary winding 13 that is connected with spark plug 5.Silicon controlled rectifier (thyristor) SCR is connected between primary air 12 and the grounding parts, and this silicon controlled rectifier SCR is connected with the trigger terminal 10 of control device 7.
Below, the effect of the embodiments of the invention with said structure is described with reference to Fig. 2 in the lump.
When ignition switch 2 was in illustrated off state, closed between a point and b point, electric current flowed to capacitor C1 by resistance R 1 from battery 1, through charging to above-mentioned capacitor C1 after the fixed time.As a result, the current potential that f is ordered becomes the 0V of earthing potential, and the current potential that e is ordered becomes the 12V that equates with the terminal voltage of battery 1.At this moment, because the breakdown voltage of Zener diode ZD1 is set at the numerical value of the appointment that is higher than 12V, is lower than 24V,, thereby can prevent capacitor C1 discharge so Zener diode ZD1 can not puncture.
When the ignition switch of ato unit being used from this state is connected, closed between c point and d point because a point and b point are separated, so the current potential that the f that is connected with the anode of battery 1 is ordered becomes 12V.As a result, because the current potential that e is ordered becomes the 24V of the high 12V of current potential of ordering than f, so Zener diode ZD1 punctures, electric current flows to the g point from the e point through Zener diode ZD1, resistance R 2 and resistance R 3.Like this, electric current just flows to the base stage of transistor T R, make this transistor T R conducting, electric current just flows to grounding parts g point from control device 7 through the collector and emitter of resistance R 4 and transistor T R, thereby makes the current potential of the igniting enabling signal terminal 9 of control device 7 become 0V near earthing potential.
Like this, when the current potential of igniting enabling signal terminal 9 became near 0V, control device 7 just judged that ignition switch 2 connected by regular ignition key, thereby by the time chien shih silicon controlled rectifier SCR action of trigger terminal 10 in appointment.As a result, the discharge current of capacitor C2 just flows through the primary air 12 of spark coil 4, in secondary winding 13 high voltage takes place, thereby makes the discharge of spark plug 5 flashings, makes engine start.
Like this, when using regular ignition key to connect ignition switch 2, but just ato unit.In addition, want not use ignition key with engine start, must make current potential that e orders and be higher than 12V, the designated value that is lower than 24V is consistent.But, the necessary for this reason Capacity of measuring capacitor C1, and owing to can not measure the Capacity of capacitor C1 with instruments such as testers simply, so, be difficult to utilize non-normal method to come ato unit.
Below, with reference to Fig. 3 the 2nd embodiment of the present invention is described.
The 2nd embodiment is between the f point and g point that resistance R 5 and resistance R 1 are connected in series in the 1st embodiment, simultaneously, capacitor C3 is connected in parallel with resistance R 1.
According to the 2nd embodiment, closed between a point and b point when ignition switch 2 is in illustrated off state, capacitor C1 charging, the current potential that e is ordered becomes the 12V that equates with the terminal voltage of battery 1, and the current potential that f is ordered becomes the 0V that equates with earthing potential.When connecting the ignition switch 2 of ato unit, a point and b point are separated, and be closed between c point and d point, so on one side to capacitor C3 charging, the current potential that f is ordered little by little rises on one side, when capacitor C3 charged electricity, the current potential that f is ordered became 12V (referring to the dotted line of Fig. 2).
As a result, because the current potential that e is ordered becomes the 24V of the high 12V of current potential of ordering than f, so the same with the 1st embodiment, Zener diode ZD1 punctures, electric current flows to the g point from the e point, transistor T R conducting, and the current potential of igniting enabling signal terminal 9 becomes 0V.So control device 7 is judged ignition switch 2 by regular ignition key connection, thereby drive ignition coil 4 makes engine start.
Like this, utilize the 2nd embodiment also can prevent to utilize non-normal method ato unit reliably.In addition, shown in the dotted line of Fig. 2, when connecting ignition switch 2, if judging current potential that e orders rises to 24V from 12V line, if permission drive ignition coil 4, suppose and use non-normal method merely the voltage of appointment to be added to the e point, also the line difference that can rise and can not ato unit owing to the current potential that e order.
Below, with reference to Fig. 4 the 3rd embodiment of the present invention is described.
The 3rd embodiment is connected Zener diode ZD2 between a point and b point of ignition switch 2, simultaneously, capacitor C4 is connected between e point and the g point.And, the current potential that e is ordered and carry out dividing potential drop and the reference potential that obtains is input to window comparison circuit IC1 with resistance R6 and 7 pairs of cell voltages of resistance R.
According to the 3rd embodiment, closed between a point and b point when ignition switch 2 is in illustrated off state, capacitor C4 charging, the current potential that e is ordered becomes the 12V that equates with the terminal voltage of battery 1.When connecting the ignition switch 2 of ato unit, because a point and b point are separated, closed between c point and d point, so, if the breakdown voltage of Zener diode ZD2 is chosen to be for example 2V, then the e current potential of ordering becomes the 10V that deducts gained behind the above-mentioned breakdown voltage 2V for the terminal voltage 12V from battery 1.
The result, if becoming, the difference of the current potential that said reference current potential and e are ordered is designated value, just from the igniting enabling signal terminal 9 output igniting enabling signals of window comparison circuit IC1 to control device 7, control device 7 is just judged ignition switch 2 by regular ignition key connection, thus the permission ato unit.
Like this, just permit ato unit during than the low given voltage of the terminal voltage of battery 1 owing to have only when formation, so, can prevent to utilize non-normal method ato unit.
Above, understand embodiments of the invention in detail, still, in the scope that does not exceed its purport, the present invention can carry out all design alterations.
For example, engine igniting circuit used for vehicles of the present invention except being applicable to two-wheeled motor vehicle, also goes for four wheeler.
As mentioned above, according to the present invention, have only when electric accumulator and battery utilize the disconnection of ignition switch to form the given voltage different with the voltage of this battery, thereby could come drive ignition coil ato unit by igniting unit.Came ato unit even can't come round to the idea ignition switch, also can be owing to the Capacity that is difficult to measure easily electric accumulator, so, can not form the voltage of above-mentioned appointment, therefore, can prevent to utilize non-normal method to come ato unit reliably.
