Safe driving support system based on mobile IoT agent and method for processing thereof
The present disclosure relates to a safe driving support system based on a mobile Internet of Things (IoT) agent, and a processing method thereof. The safe driving support system based on a mobile IoT agent may provide an accident response service for preventing a traffic accident in advance by obtaining GNSS-based position information of each of vehicles, collecting various information on a driver's status and a vehicle driving status of the vehicle that is being driven in real time to construct big data, and analyzing and repeatedly learning the collected information. According to the present disclosure, it is possible to provide the ground for providing various services capable of decreasing traffic accidents by obtaining driving information of a short cycle using a GNSS platform and analyzing the driving information to apply the driving information to traffic safety and accident prevention activities.
1. A safe driving support system based on a mobile Internet of Things (IoT) agent, comprising:
a smart band worn by a driver of a vehicle that is being driven and sensing heart rate information of the driver and acceleration information according to driver's movement;
a driver status monitoring (DSM) device installed inside the vehicle, including a first camera module, and obtaining an image including a driver's iris and face to sense driver status information;
an advanced driver assistance system (ADAS) device installed in the vehicle, including a second camera module to obtain an image around the vehicle during vehicle driving, including a radar module to sense the presence or absence of an object and a distance to the object in a surrounding situation of the vehicle, receiving vehicle driving information according to the vehicle driving from an on-board diagnostics-II (OBD2) device of the vehicle in real time to generate driver assistance information, and transmitting a notification command to the OBD2 device when an event occurs in the driver assistance information;
an advanced emergency braking system (AEBS) device generating emergency braking information and transmitting the emergency braking information to the ADAS device when the OBD2 device receives the notification command from the ADAS device and operates a brake actuator;
a global navigation satellite system (GNSS) terminal installed in the vehicle, connected to a plurality of base stations through an artificial satellite to obtain position information of the vehicle in real time, receiving the heart rate information, the acceleration information, and the driver status information from the smart band and the DSM device, receiving the driver assistance information and the emergency braking information from the ADAS device, and transmitting the position information of the vehicle, the driver status information, the vehicle driving information, and the emergency braking information; and
an accident response service server providing an accident response service so as to prevent a traffic accident by collecting the position information of the vehicle, the driver status information, and the vehicle driving information transmitted from the GNSS terminal included in each of a plurality of vehicles and analyzing and learning the collected information to detect driver's drowsy driving or notify or warn the driver of an event occurrence situation by transmitting notification information to a driver terminal when the event occurs during the vehicle driving.
2. The safe driving support system based on a mobile IoT agent of claim 1 , wherein the GNSS terminal automatically switches channel connections with adjacent base stations during the vehicle driving to correct the obtained position information in real time.
3. The safe driving support system based on a mobile IoT agent of claim 1 , wherein the accident response service server statistically analyzes the collected information to determine whether or not the event has occurred according to a driver's status and a vehicle driving status, analyzes images obtained from the first camera module to determine a driver's drowsy driving status, or analyzes a pattern of the driver status information and the vehicle driving information to predict whether or not an accident is to occur.
4. The safe driving support system based on a mobile IoT agent of claim 3 , wherein the accident response service server repeatedly learns the collected information and an analysis result so as to determine at least a driver's status, a vehicle driving status, an accident type prediction, and a road risk to construct big data for providing the accident response service.
5. The safe driving support system based on a mobile IoT agent of claim 4 , wherein the accident response service server calculates a risk index of a road on which the vehicle is being driven through the position information of the vehicle and the vehicle driving information, and provides the calculated road risk index to the driver of the vehicle that is being driven in real time.
6. The safe driving support system based on a mobile IoT agent of claim 4 , wherein the accident response service server determines whether or not the driver is in a drowsy driving status through pattern learning of the driver status information, and provides information indicating that the driver is in the drowsy driving status to the driver of the vehicle that is being driven in real time when the driver is in the drowsy driving status.
