First on-off element 200 is connected between power supply 700 and digital video recorder 100, is energized or power-off for controlling this digital video recorder 100.When first on-off element 200 is conducting state, power supply 700 is powered for this digital video recorder 100, and digital video recorder 100 is for there being electricity condition.When first on-off element 200 is off state, power supply 700 stops powering for this digital video recorder 100, and digital video recorder 100 is off-position.In the present embodiment, the first on-off element 200 comprises control end, the first path terminal and alternate path end, and control end connects second switch element 300, first path terminal and connects digital video recorder 100, and alternate path end connects power supply 700.Preferably, this first on-off element 200 is aerotron, and the base stage of aerotron is control end, and current collection is the first path terminal very, launches very alternate path end.In other embodiments, this first on-off element 200 is transistor.
Second switch element 300 is for controlling this first on-off element 200 conducting or disconnection.In the present embodiment, second switch element 300 comprises control end, the first path terminal and alternate path end, and control end connects first line 400 and the second circuit 500, first path terminal connects the first on-off element 200, alternate path end ground connection.Preferably, this second switch element 300 is aerotron, and the base stage of aerotron is control end, and current collection is the first path terminal very, launches very alternate path end.In other embodiments, this second switch element 300 is transistor.
Micro-control unit (MicrocontrollerUnit; MCU) 600, also known as one chip microcomputer (SingleChipMicrocomputer) or micro controller system, be central process unit (CentralProcessUnit; CPU) frequency and specification do suitable reduction, and by the perimeter interface such as internal memory (memory), counting machine (Timer), USB, A/D conversion, UART, PLC, DMA, even LCD driving circuit is all incorporated on one chip, form the computing machine of chip-scale, do various combination for different application scenarios and control.In the present embodiment, this micro-control unit 600 connects this digital video recorder 100 and this second circuit 500.
First line 400 is for the conducting when automobile starting and control this second switch element 300 conducting.In the present embodiment, first line 400 comprises zener diode 401 and the first diode 402, the negative electrode of zener diode 401 connects ACC shelves, and 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 control end of this second switch element 300.In addition, this first line 400 also comprises the first resistance 403 and the second resistance 404, and this first resistance 403 is connected between the negative electrode of ACC shelves and this zener diode 401, and preferably, this first resistance 403 is divider resistance, and resistance is preferably 1K Ω.Between the anode that this second resistance 404 is connected to the first diode 402 and ground, resistance is preferably 47K Ω.
Second circuit 500 is for controlling this second switch element conductive 300 when automobile flameout.In the present embodiment, the anode that the second circuit 500 comprises the second diode 501, second diode 501 connects this micro-control unit 300, and negative electrode connects the control end of this second switch element 300.
In detail, during automobile starting, connect annex (than annexes such as Source Musics) power supply by ACC shelves, ACC shelves are controlled by car key, the coupling power supply along with the startup of automobile, automobile flame-out and disconnect annex.Therefore, during automobile starting, connect first line 400 conducting of ACC shelves, that is, first diode 402 conducting of first line 400, makes second switch element 300 conducting, and then makes the first on-off element 200 conducting, thus realize power supply 700 and power to digital video recorder 100, the running data of digital video recorder 100 automobile according to described travel conditions record.
In an example, second switch element 300 is high level conducting, and the first on-off element 200 is low level conducting.Therefore, after connecting first line 400 conducting of ACC shelves, second switch element 300 conducting, by the grounded emitter of second switch element 300, the collecting electrode of second switch element 300 is connected with the first on-off element 200, when after second switch element 300 conducting, the control end voltage of the first on-off element 200 is dragged down, now the first on-off element 200 conducting, power supply 700 powers to digital video recorder 100 by the first on-off element 200.
During automobile flameout, the first line 400 be connected with ACC shelves disconnects, and that is, the first diode 402 disconnects.Now, micro-control unit 600 provides a Continuity signal (as high level signal) to the second circuit 500, makes the second circuit 500 conducting, and then makes second switch element 300 conducting, thus makes the first on-off element 200 keep conducting state.
Further, micro-control unit 600 also judges after automobile flameout whether the data processing of digital video recorder 100 completes, and continues conducting or disconnection according to described second circuit 500 of judged result control.In detail, whether micro-control unit 600 is subject to the interrupt signal that digital video recorder 100 sends judges whether the data processing of digital video recorder 100 completes by receiving.Such as, if when automobile stops, micro-control unit 300 receives the interrupt signal that described digital video recorder 100 sends, then the data processing of representative digit video cassette recorder 100 completes, then interrupt the second circuit 500.
Under normal circumstances, when automobile flameout, first line 400 are interrupted, the general also corresponding ephemeral data collecting the automobile flameout moment of camera of digital video recorder 100, digital video recorder 100 also will carry out data processing, therefore, after automobile flameout, digital video recorder 100 also needs certain hour to carry out data processing.Now, digital video recorder 100 can not send interrupt signal to micro-control unit 600, and micro-control unit 600 keeps the second circuit 500 to be conducting state, makes power supply 700 continue as digital video recorder 100 and powers.
Further, when the data processing of digital video recorder 100 completes, digital video recorder 100 sends interrupt signal to micro-control unit 600, micro-control unit 600 sends the instruction of interruption second circuit 500 after receiving this interrupt signal, the second diode 501 of the second circuit 500 is ended.The cut-off of the second diode 501 causes second switch element 300 to end, and then the cut-off of second switch element 300 causes the first on-off element 200 to end further, thus makes power supply 700 stop powering to digital video recorder 100.
According to the system of the present embodiment, by increasing by second circuit 500, thus make digital video recorder 100 when automobile flameout, first line 400 disconnect, still make power supply 700 continue as digital video recorder 100 by the second circuit 500 conducting to power, therefore effectively can prevent digital video recorder 100 from interrupting the problem of data logging when automobile flameout, and effectively improve the life-span of the element of digital video recorder.
