The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein. 
         [0008]    The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like. 
         [0009]      FIG. 1  illustrates a safe driving monitoring system  10 . The safe driving monitoring system  10  is employed in a motor vehicle to warn a driver if experiencing an abnormal driving behavior. The safe driving monitoring system  10  includes a vehicle sensing module  20 , a face capturing module  30 , a face indentifying and analyzing module  40  and a warning module  50 . 
         [0010]    The vehicle sensing module  20  is configured to sense whether the motor vehicle is moving and send a movement signal to the face capturing module  30  when the motor vehicle is moving. In the embodiment, the vehicle sending module  20  includes a road image capturing module  60  and a road image analyzing module  70 . The road image capturing module  60  is configured to continuously capture images of a road in front of the motor vehicle and send the captured images of the road to the road image analyzing module  70 . The road image analyzing module  70  is configured to compare the captured images of the road, if the captured images of the road are different, it determines that the motor vehicle is moving. The road image analyzing module  70  is further configured to send the movement signal to the face capturing module  30  if the captured images of the road are different. 
         [0011]    The face capturing module  30  is positioned before the driver. The face capturing module  30  is configured to continuously capture images of the driver according to the movement signal. The image of the driver includes the face of the driver. The face indentifying and analyzing module  40  is configured to indentify the face of the driver and analyze whether an orientation of the face is in a normal range. In an embodiment, the normal range is that the head rotates from 45 degrees to the left to 45 degrees to the right relative to the neck of the driver. The face indentifying and analyzing module  40  is further configured to send an abnormal driver signal to the warning module  50  when the orientation of the face is in an abnormal range, and identify the eyes of the driver and analyze a state of the eyes of the driver when the orientation of the face is in the normal range and send an abnormal driver signal to the warning module  50  when the eyes are closed for a period of time exceeding a preset time. In the embodiment, the preset time is two seconds. 
         [0012]    The warning module  50  is configured to warn the driver of an abnormal driving behavior according to the abnormal driver signal. In at least one embodiment, the warning module  50  includes an audio warning device. The audio warning device makes a warning sound to warn the driver. In another embodiment, the warning module  50  includes a display for displaying a flashing warning to warn the driver. 
         [0013]    In the embodiment, the face capturing module  30 , the face indentifying and analyzing module  40 , the warning module  50 , the road image capturing module  60  and the road image analyzing module  70  are integrated in a mobile phone. The road image capturing module  60  is a rear camera of the mobile phone. The face capturing module  30  is a front-facing camera of the mobile phone. The face indentifying and analyzing module  40  and the road image analyzing module  70  are image processing software installed in the mobile phone. 
         [0014]      FIG. 2  illustrates a flowchart of a safe driving monitoring method. The method includes the following blocks. In block  82 , the vehicle sensing module  20  senses the motor vehicle is moving. In the embodiment, the vehicle sensing module  20  continuously captures images of a road in front of the motor vehicle and compares the captured images of the road, and determines the motor vehicle is moving when the captured images of the road are different. The images of the road are captured by a rear camera of a mobile phone positioned in front of the driver. 
         [0015]    In block  84 , the vehicle sensing module  20  sends a movement signal. 
         [0016]    In block  86 , the road image capturing module  60  continuously captures images of the driver according to the movement signal. In the embodiment, the images of the road are captured by a front-facing camera of the mobile phone positioned in front of the driver. 
         [0017]    In block  88 , the face indentifying and analyzing module  40  indentifies the face of the driver and analyzes an orientation of the face. 
         [0018]    In block  90 , the face indentifying and analyzing module  40  determines whether the orientation of the face is in a normal range. In an embodiment, the normal range is the head rotating from 45 degrees to the left to 45 degrees to the right in relation to the neck of the driver. If the orientation of the face is in the normal range, the procedure goes block  92 , otherwise, the procedure goes block  96 . 
         [0019]    In block  92 , the face indentifying and analyzing module  40  identifies the eyes of the driver and analyzes the state of the eyes of the driver. 
         [0020]    In block  96 , the face indentifying and analyzing module  40  sends an abnormal drive signal. 
         [0021]    In block  94 , the face indentifying and analyzing module  40  determine whether the eyes are closed exceeding a preset time. If the eyes are closed exceeding the preset time, the procedure goes block  96 , otherwise, the procedure goes block  88 . In the embodiment, the preset time is two seconds. 
         [0022]    In block  98 , the warning module  50  warns the driver of an abnormal driving behavior according to the abnormal driver signal. In at least one embodiment, the warning module  50  makes a warning sound to warn the driver. In another embodiment, the warning module  50  displays a flashing warn subtitle to warn the driver. 
         [0023]    The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
