Second of example, controller 120 is sent to by the children's seat video information of collection by wireless communication module.
In this example, rear camera 110 and controller 120 all include wireless communication module, are assisted by wireless communication
Discuss transmission of video information.Wherein wireless communication module can be the common channel radio of the smart machines such as bluetooth module, WIFI module
Believe module.
Controller 120, for receiving the children's seat video information of the transmission of rear camera 110, and is sent to projector
130。
Specifically, rear camera 110 collects is converted into numeral after video information by quantifying, encoding by analog signal
Signal is sent on controller 120, and controller 120 will be sent on projector 130 after Digital Signal Processing and carry out follow-up behaviour
Make.
It should be noted that after enabling signal is set out, controller 120 is powered by cable to rear camera 110.
Projector 130, for being decoded to children's seat video information, projects to the default viewing area of front windshield
Domain.
Specifically, projector 130 receive controller 120 transmission digital signal after by decode and etc. by numeral believe
Number be converted to optical signal and project on the default region of front windshield and show.Driver can watch heel row children's
Real-time imaging.
It should be noted that default display area is does not influence the region of pilot's line of vision on front windshield, it can
Can also be set as needed by default by user, for example can be that corresponding position can also be above front passenger's seat
Position on the upper side, explanation numerous to list herein on the left of front windshield.
In conclusion the vehicle-mounted monitoring system of the utility model embodiment, gathers children's seat by rear camera and regards
Frequency information is sent to controller, and controller is sent to projector after receiving the children's seat video information that rear camera is sent,
Projector projects to the default display area of front windshield after being decoded to children's seat video information.The system is by after
The image projection of children's seat is arranged to front windshield, also ensures pilot's line of vision all the time while heel row children's situation is monitored
In front, avoid that accident occurs because pilot's line of vision disperses, improve the security of driving.
Based on above example, anticipate to further avoid driver from excessively paying attention to the picture on display area
Outside, can also by the other equipment in vehicle-mounted monitoring system to driver alarm, remind its safety traffic, below with combination before
Put camera and exemplified by buzzer alarmed, illustrate：
Fig. 3 is according to the structure diagram of the vehicle-mounted monitoring system of the utility model another specific embodiment, such as Fig. 3
It is shown, on above-mentioned vehicle-mounted monitoring system, further include：
Front camera 150, is connected with controller 120 for the visual direction for monitoring driver, as identification driver
The time for watching the display area projection video exceedes default first time threshold value, then to the controller 120 feedback the
One timeout signal.After controller 120 receives the first timeout signal of the feedback of front camera 150, if current vehicle is known in detection
Speed is more than preset vehicle speed, then is taken care driving by voice prompt driver.Front camera 150 is additionally operable to when identification drives
The time of member's viewing display area projection video exceedes default second time threshold, then to the controller 120 feedback second
Timeout signal.Wherein, the second time threshold is more than the first time threshold value.Controller 120 receives front camera 150
After second timeout signal of feedback, then sent to projector 130 and stop projection instruction, and voice prompt is carried out to driver.
It can be monitored specifically, front camera is placed on the position of driver's eyes, such as on front windshield
Side, starts to monitor the visual direction of driver when projector 130 is projected on predeterminable area.When identification driver continuously watches
The first timeout signal is fed back to controller 120 when front windshield projection video exceedes default first threshold values, if controller 120
Detect that current vehicle speed is more than preset vehicle speed then by voice prompt driver.If driver continues viewing display area, projection regards
Frequently and the duration exceedes default second time, then front camera feeds back the second timeout signal, controller to controller 120
120 control projectors 130, which stop sending, to be projected and is driven by voice reminder driver safety.
Wherein, the first threshold time, preset vehicle speed, the second threshold time can by default can also by user according to
Actual conditions are set, on the basis of ensureing safe driving.
For example, as shown in figure 4, default first threshold time is 5 seconds, it is 5m/s to preset safe speed, presets second
Threshold time is 8 seconds.Controller 120 detects current vehicle speed after driver's viewing display area projection video was more than 5 seconds, if car
Speed≤5m/s is then without circular；Taken care driving by voice reminder driver if speed >=5m/s.After voice prompt
If Driver Vision leaves video pictures, front camera 150 starts to re-recognize timing, if driver's eyes vision
Video pictures are not left also, and when 8s is arrived in accumulation, controller 120 controls projector 130 to stop sending projection and carried by voice
Driver safety of waking up drives.
Buzzer 160, buzzer 160 are connected with controller 120, are fed back when controller 120 receives front camera 150
The second timeout signal after, to buzzer 160 send warning instruction.The warning that buzzer 160 receives the transmission of controller 120 refers to
After order, buzzing reminds driver to drive with caution.
In conclusion the vehicle-mounted monitoring system of the utility model embodiment, obtains driver by front camera and watches
The time of video pictures and the speed that existing situation is detected by controller, compared with default threshold time and speed
Afterwards, if driver watches the time of video pictures and current vehicle speed exceedes default security value (s) by buzzer to driver
Send audio alert.Thus, driver attention's concentrations can effectively be prevented on video pictures, before danger occurs in time
Prompting is made, avoids unexpected generation, ensures the security driven while can monitor heel row children's seat.
