Description
Technical field
The present invention relates to the timely fatigue alarm sets that one kind uses in a vehicle, are particularly suitable for automotive field
Timely fatigue alarm set.
Background technique
With the development of highway and the raising of speed, in traffic accident, since fatigue driving causes traffic thing
Therefore occupy significant proportion, the fatigue problem of driving, it has also become a Xiang Chongdian of current automotive safety research.
The present apparatus is monitored according to the physiological characteristic of driver, and active forewarning reminds whether driver is in tired shape
State largely reduces traffic accident, to prevent due to fatigue driving cause traffic accident have great meaning
Justice.
Summary of the invention
To solve the above problems, the invention discloses a kind of timely fatigue alarm sets.The present apparatus passes through image recognition
Method, some state of mind of driver are analyzed in real time, to the timely warning reminding of the behavior of dangerous driving.Mainly
Applied to vehicle security drive field.
In order to reach the goals above, the invention provides the following technical scheme:
A kind of timely fatigue alarm set, including main control chip；The main control chip connects power supply；The main control chip
Connect memory module, data acquisition module, audio output module, communication module, GPS module, GPRS module；The memory module
Including internal storage, random access memory；The data acquisition module includes calling camera, Video Decoder；The calling
Camera acquires the facial expression of driver, and passes data to Video Decoder, and Video Decoder says that data pass to master control
Chip；The communication module includes CAN communication module, RS232 communication module, RS485 communication module.
Further, the main control chip connects crystal oscillator.Crystal oscillator is the clock frequency for controlling CPU, that is, is generated high
The low level period.
Further, the main control chip connects chip interior detection module.Internal check module can be used for detection chip
Internal operation situation it is whether normal, play the role of good detection.
Further, the main control chip connects clock module.Clock module can be effectively according to time recording camera
The internal information of the driver detected.
Further, the main control chip connects USB peripheral interface.USB peripheral interface can realize the present apparatus and external equipment
Quick connection.
Further, the main control chip is also connected with reseting module.Reseting module, which is realized, to be resetted.
Further, the main control chip uses TMS320SM64 chip, and the internal storage uses DDP memory；
The Video Decoder uses TVP5150 decoder.
The working principle of the invention:
After camera collects the facial expression of driver, TVP5150 decoding is analysed and compared by algorithm, and such as fatigue is sleepy
The driving behaviors such as sleep, yawn, glancing right and left, there is the present apparatus voice to play prompting function, and can store video, and data pass
It is defeated to have RS232, RS485, CAN, network several ways, while data can also be transmitted to by background server by 4G.
The present invention has the advantage that
The facial expression of driver can be monitored in real time, accurate judgement is in a state of fatigue, the safety of prompting reduction in time
Accident.A kind of timely fatigue alarm set, it is easy to operate, dangerous driving behavior is reminded in time, is risen in terms of automotive safety
Very big effect.
