Embodiment
With reference to accompanying drawing, preferred embodiment of the present invention is specifically described.
The present invention as shown in Figure 1, that a kind of power supply of outside is converted supply for galvanic current source by power suppling part (14), the image taken at camera lens (11) is obtained by charge coupled cell (CCD) (12), by ISP (ISP) (13) processing signals, and export the CCTV camera (10) of outside display screen to, the output signal of the power supply sent at CCTV camera (10) and image is compared with fiducial value, whether detect power supply in Power Supply Monitoring portion (30) occurs bad, whether detect image in monitoring videosignal portion (40) occurs bad, make to be shown in state display diode (50).
The conventional Power convert of outside is galvanic current source (such as, 12V or 24V) by power suppling part (14) by CCTV camera of the present invention (10).
Now, when power suppling part (14) occurs bad, CCTV camera (10) can not normally run, the current method not having can be confirmed it by naked eyes, and the applicant researches and develops one, and by simple circuit realiration, whether naked eyes monitoring power supply occurs bad.
Namely, the DC power supply of described power suppling part (14) is transferred to Power Supply Monitoring portion (30), as shown in Figure 2, described Power Supply Monitoring portion (30) by distributing resistance R1, R2 control voltage, judge whether higher than reference voltage by transistor Q1, Q2, produce high (High) or low (Low) output signal.
Even if the DC power supply that described distribution resistance R1, R2 play power suppling part (14) reaches 12V, 24V or other specific voltage, also voltage is reduced to the effect of the input voltage that Q1 and Q2 can normally run.Q1 and Q2 plays the effect of switch element, especially Q2 is when the voltage inputted is higher than reference voltage value, produces high (High) signal, when the voltage inputted is lower than reference voltage, produce low (Low) output signal, and transfer to state display diode (50).
In addition, the video signal transmission transmitted by the output of described ISP (ISP) (13) is to monitoring videosignal portion (40), judge that whether vision signal is higher than baseline signal value described monitoring videosignal portion (40), produce high (High) or low (Low) output signal.
Described ISP (ISP; ImageSignalProcessor) for the signal of telecommunication changed at imageing sensor (charge coupled cell etc.) being converted to the device of signal of video signal, when ISP is complementary metal oxide semiconductors (CMOS) (CMOS) transducer, can be able to realize with monolithic (OneChip), when amplifying, be configured at back-end chip (BackendChip) with the chip of Digital Signal Processing (DSP) and system single chip (SoC) form.Omit the content that it is concrete in the present invention.
One embodiment of the invention, as shown in Figure 3, removed the brightness being contained in vision signal by brightness removal unit (41) in described monitoring videosignal portion (40), any one above video synchronization signal in vertical synchronization or horizontal synchronization is only detected by synchronization signal detection portion (42), after removing noise by filter (43), judge whether higher than baseline signal value.
Namely, because vision signal must comprise synchronizing signal with certain hour interval, thus, when analyzing the pattern of this synchronizing signal, judge whether vision signal is normal state, but the present invention receives the vision signal transmitted by ISP (13), and only detect the synchronizing signal (syncsignal) being contained in described vision signal, judge that whether vision signal is normal.
Utilize the method and the synchronizing signal that detects that detect described synchronizing signal and judge the existing known technology of approach application whether vision signal normally exports.Such as, utilize the vertical bar of winding around also can detect synchronizing signal, utilize magnetic field also can detect synchronizing signal.
Described synchronizing signal comprises horizontal synchronization (Horizontalsynchronizingsignal; Horizontal-drive signal) and vertical synchronization (Verticalsynchronizingsignal; Vertical synchronizing signal).
Horizontal-drive signal and vertical synchronizing signal are for making the square-wave signal that the starting point of vision signal is consistent, by with the opposite polarity pulse signal transmission of signal of video signal to the horizontal vertical field flyback of signal of video signal or perpendicualr field flyback.Now, vertical synchronizing signal is compared with horizontal-drive signal, and the duration is long, thus easily judge whether normal, thus, in the present invention, first time is suitable for.
Therefore, the state that the output signal (high signal or low signal) transmitted by described Power Supply Monitoring portion (30) and monitoring videosignal portion is transferred to the side being arranged on CCTV camera (10) shows diode (50), thus, the running status of CCTV camera (10) can be judged.
Namely, the present invention is according to the bright light of output signal adjustment state display diode (50) transmitted by described Power Supply Monitoring portion (30) and monitoring videosignal portion (40), and real-time display power supply cuts off, normal, power supply is bad, whether bad video is.
One embodiment of the invention, described state display diode (50) uses display a kind of surface mount to three kinds of colors (SMD) light-emitting diode, as shown in Figure 1, turn off the light when not having power supply to supply (51), when power supply occurs bad, shiny red (RED) (52), when vision signal occurs bad, sapphirine (BLUE) (53), during for normal condition, bright green (GREEN) (54).
And the color according to state bright light can convert, and, also can be divided into multiple diode, and realize in the mode of bright light.
The present invention as above is not defined in above-mentioned specific embodiment, when not departing from the main idea of the present invention of this claim, those skilled in the art anyone can carry out various distortion implement.
