DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a vehicle impact recording and real-time image transmission system according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a block diagram of a system for impact recording and real-time image transmission of a vehicle according to a preferred embodiment of the present invention.

The shock recording and real-time image transmission system of the vehicle according to the present invention includes an image photographing unit 10, an impact recording and real-time image transmission unit 20, a relay server 30, and a mobile device 40.

In addition, the impact recording and real-time image transmission system of the vehicle of the present invention may further comprise a vehicle battery 50, a can communication unit 60, and an external storage device 70.

The image photographing unit 10 photographs a surrounding image of a vehicle. The image capturing unit 10 may include an RR camera for capturing the back of the vehicle, a front camera (FRT camera) for capturing the front of the vehicle, an AROUND VIEW CAMERA, and an LDWS CAMERA.

The shock recording and real-time image transmission unit 20 stores the image captured by the image capturing unit 10 and transmits the image data stored when the shock of the vehicle is sensed to the registered mobile device 40 or real- It plays a supporting role.

The shock recording and real-time image transmission unit 20 includes a sensor unit 21 for detecting a vehicle impact; An image capturing unit 23 for capturing an image captured by the image capturing unit 10; A memory unit 25 for storing the image collected by the image collection unit 23; A communication module 26 for transmitting video data stored in the memory unit 25 to a registered mobile device or supporting real-time streaming; And a control unit 27 for controlling the sensor unit 21, the image capturing unit 10, and the communication module 26 to control the impact recording and real time image transmission.

Where the communications module 26 may utilize LTE communications and / or short range wireless communications (Wi-Fi, Bluetooth, etc.).

The control unit 27 transmits an event occurrence to the mobile device 40 in the form of a text message (SMS) or a push alarm when the event occurs due to a vehicle impact so that the mobile device 40 can monitor the vehicle in real time .

Also, the impact recording and real-time image transmission unit 20 includes an auxiliary battery 29 for supplying an auxiliary power source to prevent information loss due to system damage and power interruption that may occur between vehicle impacts; A power supply 22 for power supply; An image processing and transmitting unit 28 for image processing and transmission, and a GPS module 24 for receiving GPS signals via GPS satellites.

The relay server 30 functions to relay command and image transmission information between the mobile device 40 and the impact recording and real-time video transmission unit 20. [

The mobile device 40 receives an event alarm transmitted from the impact recording and real-time video transmission unit 20 in conjunction with the relay server 30, and confirms and manages event data, And stores the real-time transmitted image. To this end, the mobile device 40 preferably includes an application for receiving event alarms, checking and managing event data, and supporting functions for real-time camera shot image transmission.

In addition, the external storage device 70 backs up data stored in the internal memory to prevent data loss caused by power interruption or internal memory damage, and the vehicle battery 50 supplies driving power And the can communication unit 60 receives the vehicle speed, the RPM, and the like, and transmits the received information to the impact recording and real-time image transmission unit 20. [

The impact recording and real-time image transmission system of the vehicle according to the present invention will be described in detail as follows.

The shock recording and real time video transmission unit 20 charges the auxiliary battery 29 with the power supplied from the vehicle battery 50 and the power supply unit 22 And supplies driving power to each of the cameras in the image capturing unit 10. [0050]

When the initialization is completed, the control unit 27 switches to the standby state for impact monitoring, image storage and management, image transmission, and the like.

In the standby state, the sensor unit 21 continuously monitors whether or not an impact has occurred in the vehicle. Here, the sensor unit 21 may use various shock sensors for detecting the impact of the vehicle. In the present invention, a three-axis acceleration sensor is used.

The sensor unit 21 transmits a vehicle impact detection signal to the control unit 27 when it is detected that a vehicle impact has occurred while continuously monitoring whether or not a vehicle impact has occurred. The control unit 27 collects vehicle surroundings and / or internal images taken by the image pickup unit 10 through the image pickup unit 23 when a vehicle impact detection signal is transmitted. Then, the collected image data is stored in the memory unit 25.

One of the features of the present invention is that when image data is stored in the memory unit 25, the image data is stored in a backup form in the external storage device 70 at the same time, thereby preventing data loss even when the internal memory is damaged due to a shock . That is, the image data primarily collected is stored in the internal memory unit 25 and simultaneously stored in the external storage device 70 to prevent data loss.

Here, when storing the image data, it is preferable to store the vehicle information (vehicle speed, RPM, etc.) acquired in the event of an impact through the can communication unit 60 and the current time information acquired through the GPS module 24 together.

Next, the control unit 27 generates an event generation signal such as an SMS or a push alarm when a vehicle impact occurs, and transmits the generated event generation signal to the relay server 30 through the communication module 26. And transmits the image data (including the vehicle information) stored in the memory unit 25 to the relay server 30 through the communication module 26 in real time or periodically.

When the relay server 30 receives the SMS or the push alarm, the relay server 30 transmits it to the mobile device 40 and then transmits the image data transmitted from the impact recording and real-time image transmission unit 20 to the mobile device 40 . The command signal generated from the mobile device 40 is relayed to the impact recording and real-time video transmission unit 20.

Here, as another feature of the present invention, an auxiliary battery 29 is added in order to prevent information loss due to system damage and power shutdown when an impact occurs in a vehicle. The auxiliary battery 29 discharges the stored power and supplies the driving power to the required part continuously through the power supply unit 22 when system damage or power cut-off occurs due to the occurrence of a vehicle impact. Therefore, even when system damage or power cut-off occurs due to the impact of the vehicle, power is constantly supplied to the impact recording and real-time video transmission unit 20, and the vehicle or surrounding images can be captured, stored, and transmitted.

On the other hand, when the mobile device 40 receives an event signal due to the occurrence of a vehicle impact through the relay server 30, it executes the vehicle monitoring application stored therein to switch to the vehicle monitoring mode. In a state of switching to the vehicle monitoring mode, the image data received through the relay server 30 is received and stored, and displayed on the display device. Therefore, the driver can monitor the vehicle condition in real time even when the vehicle is running or when the vehicle is turned on, even when the vehicle is away from the vehicle. When the image transmission or other command signal is generated as needed, the relay server 30 relays it to the impact recording and real-time image transmission unit 20.

Here, the command information includes command information for accessing the backup space to reproduce, delete, and download data.

In addition, according to another embodiment of the present invention, when an impact occurs in a vehicle in a state where the vehicle is turned off and parked or stopped, the sensor unit 21 senses the impact and transmits the shock to the control unit 27. The control unit 27 is automatically activated by the wake-up function when a vehicle impact detection signal arrives while the vehicle is in the off state. Thereafter, an event signal for the occurrence of a vehicle impact is generated and transmitted to the relay server 30 through the communication module 26.

The relay server 30 transmits the transmitted event signal to the mobile device 40. The driver recognizes that an abnormality has occurred in the vehicle through the generation of an event signal at a remote location remote from the vehicle.

Then, the camera is selected through the mobile device 40, and a command signal for transmitting the camera image in real time is transmitted. The command signal thus transmitted is transmitted to the impact recording and real-time image transmission unit 20 through the relay server 30.

The impact recording and real-time image transmission unit 20 operates the camera of the image capturing unit 10 according to the transmitted command, collects the image data photographed by the camera, and stores the captured image data in the memory unit 25 and the external storage device 70 At the same time, the image is photographed in real time through the real-time streaming function, and is transmitted to the mobile device 40 through the communication module 26.

Accordingly, the driver can monitor the state of the vehicle using the mobile device 40 at a position away from the vehicle, and if the occurrence of the vehicle abnormality is detected, the driver can take appropriate follow-up measures promptly to prevent further damage.

5, when the mobile device 40 issues a real-time image transmission command when an event occurs during parking or stopping, the image capturing unit 10, the impact recording and real-time image transmission unit 20, and the relay server 30, FIG. 4 is a flow chart illustrating a process of streaming a captured image to the mobile device 40 in real time through interlocking between the mobile device 40 and the mobile device 40.

FIG. 6 shows a process of streaming a recorded image between the relay server 30 and the mobile device 40, and searching and managing necessary images.

FIG. 4 is a flow chart for performing image transmission or video streaming in response to a shock detection (S11) of a vehicle and a starting state of the vehicle (S12).

The camera image is collected (S13), the event image is stored (S14), and the event image stored in the memory is transmitted to the mobile device 40 in real time or periodically (S15).

If the vehicle is turned off, the system automatically wakes up the system (S16) and generates an event signal to the mobile device 40 (S17). Then, the mobile device 40 designates the IP address of the camera modem to select the camera (S19), and then streams the camera image to the mobile device in real time (S19).

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.
