Road 500, the first path terminal connection first switch element 200, alternate path end ground connection.Preferably, the second switch element 300 is
Audion, the base stage of audion is control end, and current collection extremely the first path terminal launches extremely alternate path end.In other enforcements
In example, the second switch element 300 is transistor.
Micro-control unit (Microcontroller Unit；MCU) 600, also known as one chip microcomputer (Single
Chip Microcomputer) or single-chip microcomputer, it is central processing unit (Central Process Unit；CPU frequency)
Appropriate reduction is done with specification, and by internal memory (memory), enumerator (Timer), USB, A/D conversion, UART, PLC, DMA isoperimetric
Side interface, or even LCD drive circuits are all incorporated on one chip, form the computer of chip-scale, are different application scenarios
Do various combination control.In the present embodiment, the micro-control unit 600 connects the digital video recorder 100 and second line
Road 500.
First line 400 is used to turn in automobile starting and control the second switch element 300 to turn on.In the present embodiment
In, first line 400 includes the diode 402 of zener diode 401 and first, and the negative electrode of zener diode 401 connects ACC shelves,
The anode of zener diode 401 connects the anode of the first diode 402, and the negative electrode of the first diode 402 connects the second switch
The control end of element 300.Additionally, the first line 400 also includes first resistor 403 and second resistance 404, the first resistor

Second circuit 500 is used to control the second switch element conductive 300 in automobile flameout.In the present embodiment,
Two circuits 500 include the second diode 501, and the anode of the second diode 501 connects the micro-control unit 300, and negative electrode connection should
The control end of second switch element 300.
In detail, during automobile starting, adnexa (than adnexaes such as Source Musics) power supply can be connected by ACC shelves, ACC shelves are by car
Key controller, connects accessory power supply with the startup of automobile, automobile flame-out and disconnect adnexa.Therefore, during automobile starting, even
The first line 400 for connecing ACC shelves is turned on, that is to say, that the first diode 402 of first line 400 is turned on, and makes second switch unit
Part 300 is turned on, and then turns on first switch element 200, so as to realize that power supply 700 is powered to digital video recorder 100, number
Word video cassette recorder 100 records the running data of the automobile according to the travel conditions.
In an example, second switch element 300 is high level conducting, and first switch element 200 is low level conducting.
Therefore, after connecting the conducting of first line 400 of ACC shelves, second switch element 300 is turned on, by the transmitting of second switch element 300
Pole is grounded, and the colelctor electrode of second switch element 300 is connected with first switch element 200, after second switch element 300 is turned on,
The control terminal voltage for making first switch element 200 is pulled low, and now first switch element 200 is turned on, and power supply 700 is opened by first
Close element 200 to power to digital video recorder 100.
During automobile flameout, the first line 400 being connected with ACC shelves disconnects, that is to say, that the first diode 402 disconnects.This
When, micro-control unit 600 provides a Continuity signal (such as high level signal) to the second circuit 500, turns on the second circuit 500,
And then second switch element 300 is turned on, so that first switch element 200 is tended to remain on.
Further, micro-control unit 600 also judges that the data processing of digital video recorder 100 is after automobile flameout
It is no to complete, and continue to be switched on or off according to judged result control second circuit 500.In detail, micro-control unit 600
By whether receiving the interrupt signal by the transmission of digital video recorder 100 to judge the data of digital video recorder 100
Whether process completes.For example, if automobile stops, micro-control unit 300 receives the transmission of the digital video recorder 100
Interrupt signal, then it represents that the data processing of digital video recorder 100 is completed, then interrupt the second circuit 500.
Under normal circumstances, when automobile flameout, first line 400 are interrupted, the photographic head of digital video recorder 100 is general
Correspondence collects the ephemeral data at automobile flameout moment, and digital video recorder 100 will also carry out data processing, therefore, in vapour
Digital video recorder 100 also needs to certain hour after car is flame-out carries out data processing.Now, digital video recorder 100 will
Interrupt signal will not be sent to micro-control unit 600, it is conducting state that micro-control unit 600 keeps the second circuit 500, makes power supply
700 continue as digital video recorder 100 powers.
Further, when the data processing of digital video recorder 100 is completed, digital video recorder 100 is to micro-control
Unit processed 600 sends interrupt signal, and micro-control unit 600 receives and the finger for interrupting the second circuit 500 is sent after the interrupt signal
Order, the second diode 501 for making the second circuit 500 ends.The cut-off of the second diode 501 causes 300 sections of second switch element
Only, and then, the cut-off of second switch element 300 further results in first switch element 200 and ends, so that power supply 700 stops
Power to digital video recorder 100.
According to the system of the present embodiment, by increasing by second circuit 500, so that digital video recorder 100 exists
When automobile flameout, first line 400 disconnect, remain to make power supply 700 continue as digital video recorder by the conducting of the second circuit 500
Machine 100 is powered, therefore can effectively prevent digital video recorder 100 from interrupting the problem of data record in automobile flameout, and
And effectively improve the life-span of the element of digital video recorder.
