Lower scheme：Reverse image is mainly realized by the reverse image switch in the Level-3 menu of Big Dipper terminal, and the letter for accessing
Number use hard signal；When manual unlocking reverse image function, after Big Dipper terminal receives astern signal, automatically into
Reverse image interface, but due to the particularity of commercial car, it is impossible to determine below get rid of which kind of form extension is, therefore reversing shooting
Head cannot be good to user installation as front filling, and can only install photographic head by user's later stage.There is problems with this kind of scheme：1、
If later stage user does not install photographic head, the reverse image interface for entering is exactly black, causes user to be mistakenly considered damage of product,
Increase rate of freight compensation and reduce the comfortableness that user uses；2nd, the situation that user cannot be observed when not moveing backward after car, when with
After family triggering astern signal, be fitted without photographic head to cause screen to be in black due to user.
Therefore, comprehensive consideration devises a kind of reverse image system based on Big Dipper terminal of the design, including Big Dipper terminal
With photographic head（If installing）, Big Dipper terminal includes master terminal MCU, secondary terminal MCU, display screen, photographic head detection module, reversing
Signal acquisition module, is provided with shooting Head icon and reversing icon on the display screen, the shooting Head icon, reversing icon are equal
It is connected with secondary terminal MCU signal；During vehicle release, reverse image function acquiescence is closed, and images Head icon gray；As user
During one click shooting Head icon, photographic head is checked signal transmission to secondary terminal MCU by display screen, and secondary terminal MCU is detected to be taken the photograph
As the voltage of the power supply circuits of head is more than or equal to 5 volts, then it represents that Big Dipper exterior of terminal has been mounted with photographic head, secondary terminal MCU
Control shooting Head icon carries out set and becomes highlighted state, and reverse image function is activated, if being not detected by photographic head, moves backward
Imaging function can not be activated, by the way of automatic detection photographic head, it is to avoid miss claim issue without caused by photographic head,
Improve product reliability energy；Only after Head icon being imaged in highlighted state, could enter reversing interface, when photographic head figure
When mark is in Lycoperdon polymorphum Vitt, even if giving astern signal, interface of moveing backward also is cannot be introduced into；After reverse image function is activated, master terminal
MCU detects astern signal by astern signal acquisition module 5, after master terminal MCU receives astern signal, by secondary terminal MCU
The display screen picture of control Big Dipper terminal switches to reversing interface；After clicking on reversing icon, directly enter by secondary terminal MCU
Car interface, user is not when reverse gear is hung, it is also possible to see that the picture after car, such design have respected fully thinking for user
Method, embodies the design concept of consumer uppermost.
