Allow to drive 3004 starter motor 10 of microprocessing unit, and the automatically controlled microprocessing unit 3204 of magnetic strength can just be allowed to pass through switch 42
Start magnetic strength electronic control unit 3202.
Fig. 2A and Fig. 2 B is please referred to according to Fig. 1, Fig. 2A is that the automatically controlled microprocessing unit 3204 of magnetic strength of the present invention is detected effectively
The signal schematic diagram of signal time-histories value in pulse wave width modulation signal.Fig. 2 B is that the present invention driving detecting of microprocessing unit 3004 has
Imitate the signal schematic diagram of signal time-histories value in pulse wave width modulation signal.We are further illustrated with Fig. 1, Fig. 2A and Fig. 2 B
Bright, the abscissa of Fig. 2A and Fig. 2 B is time shaft, and ordinate is voltage.
The signal time-histories value can also be with one other than representing the signal time-histories of effective pulse wave width modulation signal
The time-histories ratio of useful signal replaces in the pulse wave time-histories 50 in a period.Effective pulse wave width modulation signal is in illustrated example
In be electronic signal of the lift-rising to 5 volts (V), other 0 volt is then invalid pulse wave width modulation signal.
So as shown, the pulse wave time-histories 50 of pulse wave width modulation signal is all 50 milliseconds (ms), it is equal to one according to legend
The signal period is exactly a pulse wave time-histories 50, and the first pulse wave width modulation signal 51 and the second pulse wave width modulation signal 52 have
The signal in two periods provides the confirmation more more reliable than independent a cycle signal, so in 100 milliseconds for starting starting,
All testing whether the first pulse wave width modulation signal 51 and the second pulse wave width modulation signal 52 have effective pulse bandwidth tune
Become the signal specific time-histories value or time-histories ratio of signal.It is assumed that the first pulse wave width modulation signal 51 and the second pulse bandwidth tune
It is 5 milliseconds that the signal time-histories value for becoming effective pulse wave width modulation signal of signal 52 all defines respectively, so effective pulse bandwidth
The specific time-histories ratio of modulation signal is then 10% (5 milliseconds/50 milliseconds) respectively.
Then, the 100th millisecond to 200 milliseconds of period, it is wide with the 4th pulse wave just to detect third pulse wave width modulation signal 53
Spend modulation signal 54 whether signal specific time-histories value or time-histories ratio with effective pulse wave width modulation signal, during this section
All there are two the signals in period respectively for same third pulse wave width modulation signal 53 and the 4th pulse wave width modulation signal 54.It is assumed that
When the signal of effective pulse wave width modulation signal of third pulse wave width modulation signal 53 and the 4th pulse wave width modulation signal 54
All definition is 10 milliseconds to journey value respectively, so the specific time-histories ratio of effectively pulse wave width modulation signal is all 20% (10 respectively
Millisecond/50 milliseconds).
It connects again, the 200th millisecond to 300 milliseconds of period just detects the 5th pulse wave width modulation signal 55 and the 6th pulse wave
Whether width modulation signal 56 has the signal specific time-histories value or time-histories ratio of effective pulse wave width modulation signal.It is assumed that the
The signal time-histories of effective pulse wave width modulation signal of five pulse wave width modulation signals 55 and the 6th pulse wave width modulation signal 56
All definition is 15 milliseconds to value respectively, so the time-histories ratio of effectively pulse wave width modulation signal is all 30% (15 milliseconds/50 respectively
Millisecond).
So when the automatically controlled microprocessing unit 3204 of magnetic strength detects the signal time-histories of the first pulse wave width modulation signal 51
Value, and after the signal time-histories value for driving microprocessing unit 3004 to detect the second pulse wave width modulation signal 52, measured first
When the signal time-histories value of pulse wave width modulation signal 51 and the second pulse wave width modulation signal 52 is all 5 milliseconds respectively, that is,
In 52 signal of first pulse wave width modulation signal 51 and the second pulse wave width modulation signal effective pulse wave width modulation signal when
When journey ratio is all 10% respectively, it can just continue to send out third pulse wave by driving microprocessing unit 3004 at the 100th millisecond
Width modulation signal 53, and the automatically controlled microprocessing unit 3204 of magnetic strength sends out the 4th pulse wave width modulation signal 54.
It connects, when the automatically controlled microprocessing unit 3204 of magnetic strength detects the signal time-histories of third pulse wave width modulation signal 53
Value, and after the signal time-histories value for driving microprocessing unit 3004 to detect the 4th pulse wave width modulation signal 54, measure third arteries and veins
When the signal time-histories value of wave width modulation signal 53 and the 4th pulse wave width modulation signal 54 is all 10 milliseconds respectively, that is, the
The time-histories of effective pulse wave width modulation signal in three pulse wave width modulation signals 53 and 54 signal of the 4th pulse wave width modulation signal
When ratio is all 20% respectively, it can just continue to send out the 5th pulse wave by driving microprocessing unit 3004 at the 200th millisecond wide
Modulation signal 55 is spent, and the automatically controlled microprocessing unit 3204 of magnetic strength sends out the 6th pulse wave width modulation signal 56.
Finally, when the automatically controlled microprocessing unit 3204 of magnetic strength detects the signal time-histories of the 5th pulse wave width modulation signal 55
Value, and after the signal time-histories value for driving microprocessing unit 3004 to detect the 6th pulse wave width modulation signal 56, measure the 5th arteries and veins
When the signal time-histories value of wave width modulation signal 55 and the 6th pulse wave width modulation signal 56 is all 15 milliseconds respectively, that is, the
The time-histories of effective pulse wave width modulation signal in five pulse wave width modulation signals 55 and 56 signal of the 6th pulse wave width modulation signal
When ratio is all 30% respectively, just allow to drive 3004 starter motor 10 of microprocessing unit, and also just allow to keep magnetic strength automatically controlled
Microprocessing unit 3204 starts magnetic strength electronic control unit 3202 by switch 42.
Referring to Fig. 3, Fig. 3 is the flow chart of present invention starting control method.For up to the advantage at least one or
