Embodiment
The present invention will be further described below in conjunction with accompanying drawing
Main frame (see figure 9): the room mirror (interior configuration is made a video recording first) of band TFT display.
Native system adopts brake signal, engine signal, astern signal, ignition switch to come the action of control system, and these signals are all taken from vehicle interior, signal are incorporated into the corresponding I port (see figure 6) of MCU (U6) by connectivity port J7, the J8 of system.U6 port function: AP: control port; PB0: operation; PB1: reversing; PB2:VIDEO-IN; PB3: ignition switch; PC0:NC; PC1: browse state; The PC2:TFT switch; PDO: screen shows control; PD1:LCD control; PD2: video state detects; PD3: power state detection; PE:OSD control; The control of PF0:DSP power supply; PF1: prompt tone.Interface J7:1:12V-IN; 2:GROUND.Interface J8:1: brake; 2: reversing; 3:Video-IN, 4: ignition switch.
When car starts, when MCU (U6) detected ignition switch and has signal to pass over, system started through behind the suitable time-delay, and the TFT display screen is opened and also shown the place ahead image.MCU can continuously detect other signals simultaneously, MCU (U6) sends instruction when not having brake signal when detecting, DSP (U1) begins the data that collect from Sensor (independent PCB) are compressed, be saved among the Flash then, Flash leaves independently one in above the PCB, and purpose is to increase data security.(system also supports other storage mediums such as SD, MMC, CF, SMC etc.).After having detected brake signal and having continued some seconds, MCU sends halt instruction, and DSP stops data acquisition.
After the Flash storage was full, MCU switched to data bus above the another one Flash fast, thereby realized the continuous storage of data, and when DSP write current Flash with data, MCU formatd another Flash, and the data of waiting for next time write.
At any time, when MCU has detected astern signal (when moveing backward), display screen is transformed into the signal of back camera automatically.If this moment, display screen was in closed condition, then to open automatically, reversing is closed after finishing automatically.The switching of front and back vision signal does not influence collection, the store status of data.
Display screen extinguishes after showing 3 minutes automatically.The TFT-CTL key can be opened once more, and keeps 3 minutes.Can not close at browse state and reversing state display screen.
During switch-off, ignition signal disappears, and MCU sends END instruction, and system preserves the data of having gathered, and closes then.
When causing system cut-off as the accident generation, the 12V of J71 pin disappears, and MCU can start standby power supply, data reliably can be preserved equally.
At non-recording status, when promptly stopping, can browse the video data stored of resetting.
When accident takes place, can press the protection button, can protect the video data that has write down.
The module brief introduction
The DSP digital signal processor; Native system is used for audio frequency and video are carried out the core of acquisition process.Adopt special DSP, can carry out Real Time Compression, decompression, storage, playback etc. to audio-video signal with multiple form.
SDRAM random data storer; Be used to deposit intermediate data.Because a large amount of computation process is being compressed, had when decompressing to data especially video data, having some ephemeral datas therebetween need deposit, and requirement has the access time fast, instruction code also will download among the Ram and carry out simultaneously, so system disposition a slice SDRAM is used for above operation, the amount of capacity of SDRAM is according to actual needs from 32M～256M configuration.
Flash NAND type flash memory; Deposit data through overcompression.Because refreshing of Flash needs the regular hour, and prolongs along with the increase of capacity, be equipped with 2 Flash for this reason, a slice storage therein completely need be formatd it, and this moment is by another Flash storage data, thus the uninterrupted storage of realization data.
The supply of POWER system power supply; Adopt the Frequency-variable Modulation technology to modulate, isolate the power supply system use of various different magnitudes of voltage again with LDO type IC taking from outside 12V power supply.Native system is also considered the singularity of environment for use and has been equipped with a Battery pack, uses for reference the UPS principle, when having accident to cause system cut-off, changes battery-powered, has at utmost guaranteed the stability and the safety of data of system.When car starts, then the S12V end has, the Q11 saturation conduction, the collector low level, Q12 conducting system powers on, MCU work IO17 output high level, under the normal condition after the Q12 conducting 12V provide a faint electric current of keeping by D9 to battery, cell voltage is added to the S end of Q12 by D4 and since this moment the Q12S end voltage be 12V, and cell voltage is 6V, therefore do not have electric current and flow through, only when the disappearance of VBAT (taking from storage battery) terminal voltage, storage battery outage just, cell voltage provides the power supply supply by D4 to system, simultaneously continue to keep high level at outage moment MCU, and send END instruction, what the data of collection also can safety deposits among the Flash, 2 level, system cut-off are hanged down in IO17 output then.By above-mentioned measure and ensure safety of data.
HOST provides the port with dataphone; Be connected with computer for convenient, this machine is useful on the USB port with the PC communication.Browse state insert the USB connecting line can be with system in video data stored copy in the computer and preserve, this moment, system just was equivalent to a USB flash disk, using method is identical with USB flash disk.
Sensor imageing sensor (camera); The ImageSensor that can directly connect the plurality of specifications model.DSP can be directly and the Sensor communication, carries out related setting and data back DSP is handled.
The input of TV_in/Audio_in video/audio signal; Directly video, the sound signal of input standard are imported DSP through conversion with data and are handled.System just can accept any front end signal that meets video, audio standard like this.
The output of TV_Out vision signal; The image that image that front end Sensor gathers or playback have been preserved all can be by the TV of TV_out output or above the other display equipment.
The output of Audio_Out audio frequency; Synchronous playing gather or sound signal.
The output of Digital Out digital video; Support multiple main flow numeral TFT display screen to connect, enable direct display image.
The MCU single-chip microcomputer; The core of system control, the outside control signal of introducing as: realization of the various functional statuses of ignition switch signal etc., speed of a motor vehicle calculating, multiple point distance measurement, system or the like all is to control, handle by MCU, also is the key that the function of system realizes.After system powered on, MCU is each IO of initialization at first, and each IC is carried out initializing set, realizes different actions according to the state of control port then.As being automatically demonstration to be switched to above the camera of back when detecting astern signal, when having detected brake signal and having stopped video recording after continuous 15 seconds automatically, brake signal disappears and continues video recording again.
Multi-path monitoring; According to different demands, can be equipped with 1 to 4 road monitoring cameras, so just can carry out the omnibearing real-time monitoring of multiple spot to monitored object.
Multiple point distance measurement; Adopt the multiple spot ultrasonic ranging system to realize the real time distance of multiple spot, on display device, show during reversing, for the user provides real time data intuitively.
Speed of a motor vehicle induction; Independently a real-time speed of a motor vehicle induction system can show, write down real-time vehicle speed data.For evidence obtaining in the future provides reference.
