Description

Technical Field [0001] The present invention relates to a method of providing a black box for a vehicle,

The present invention relates to a method of providing image data of a black box for a vehicle in cooperation with a GIS (geographic information system), and more particularly, The present invention relates to a video data service method for a vehicle black box, which enables video data to be checked in cooperation with a GIS in a mobile terminal and can monitor the operation of a black box with a mobile terminal.

In general, the Black Box is a device used to analyze the status of aircraft accidents. The black box is originally developed for aircraft and serves to record the status of the aircraft, such as altitude, route, speed, engine status, and communications. Therefore, it is very helpful to accurately identify the accident situation of the aircraft when the incident is recovered after analysis.

Today, black boxes are used in cars as well as aircraft. Car black boxes are sometimes called 'EDR (Event Data Recorder)', but they are mostly camera type products. It is mainly installed near the room mirror inside the vehicle or on the dashboard. It is mainly used to record the video of the front of the vehicle and to record the moving image and to prevent the occurrence of a traffic accident.

Depending on the product, two or more cameras may be installed. In some cases, such as a taxi or a bus, an unspecified number may be photographed at the same time. do. In addition to this, there are a product that always shoots while driving, a product which captures a sudden movement of a vehicle to capture only a collision moment, or a product that operates only when parking, and the like. There are many cases. There is also an integrated black box with navigation and high pass functions.

In addition to being fitted separately by the driver, the car maker may initially install a black box. In this case, the pedal (accelerator), the operation of the brake or the steering wheel (steering wheel), the speed of the vehicle, and the status of the seat belt are recorded.

Conventionally, a photographing apparatus mounted on a vehicle black box stores image data photographed in real time in a storage device, thereby providing a record of a safety accident occurring during driving of the vehicle or during driving of the vehicle. However, the image data photographed by the photographing apparatus of the black box can be confirmed by a monitor provided in the black box or by separating the storage apparatus from the black box and reproducing the image data.

Therefore, in a situation where a vehicle is parked or stopped remotely and the vehicle is damaged due to a collision or intention from the outside, there is a problem in that it can not be known through real time. That is, even if the photographing device of the black box mounted on the vehicle for the collision accident or damage of the vehicle is photographed in the vicinity of the vehicle, since it is necessary to check the image data after the photographing, it is difficult to take immediate action, I had a problem. In response to such a problem, a method of storing and transmitting image data stored in a black box has been applied.

As a prior art related to a method of storing and transmitting image data stored in a vehicle black box, Patent Document 1 collects traffic information or vehicle information from a vehicle black box equipped with a communication module, transmits the traffic information or vehicle information to a cloud computing storage server, A cloud computing storage server stores traffic information or vehicle information, and then backs up the traffic information or vehicle information to a backup server, thereby preventing loss of information and facilitating management. It is difficult to store and manage vast amounts of information on cloud computing storage servers, although the traffic information and vehicle information collected from the vehicle black box is transmitted to and stored in the cloud computing storage server.

Also, Patent Document 2 discloses a mobile terminal capable of wirelessly transmitting / receiving data with a user terminal capable of wireless communication, storing a vehicle terminal mounted on the vehicle and a plurality of applications, And a cloud server for receiving the data of the user terminal and the data of the vehicle terminal and storing the data. It is difficult to manage vast amount of information stored in the cloud server because it receives and stores the user terminal data and the vehicle terminal data in the cloud server.

In addition, in Patent Document 3, when an information collecting device provided in a vehicle determines that an event has occurred in a vehicle, it requests the video devices to be information about the photographed image of the scene related to the metadata-event, So that only images related to an event can be provided again. In this case, it is possible to acquire images of surrounding objects according to the occurrence of an event to grasp the events. However, there is a problem that the generated events can not be coped with in real time, and data storage and management problems arise.

Patent Document 4 discloses that vehicle driving data is collected from a vehicle terminal installed in a vehicle, and the collected vehicle driving data is stored in a database and provided to users. This means that there is a large amount of vehicle driving data generated in the vehicle and there is a problem in storing and managing it.

In addition, Patent Document 5 discloses a method of detecting an accident by using vehicle driving data that can acquire data related to the accident through a route diverted to a vehicle terminal and a mobile terminal when an accident occurs in a vehicle . This is problematic in storing, utilizing, and managing large amounts of vehicle operation data depending on the severity of a vehicle accident.

As described above, although the prior arts have been installed in the vehicle to photograph and record images outside the vehicle, the black box for a vehicle stores the captured image data in various storage media so that it can be used as a post-evidentiary event according to the occurrence of an accident. However, In addition to not being able to accurately communicate the current situation, it can not solve the problem that can be derived, but also has a problem that the operation of the vehicle black box can not be remotely detected, controlled and utilized.

The illuminating device 20 is adapted to emit light when the periphery of the vehicle is below a predetermined illuminance so as to improve the sharpness of the image taken from the photographing device 18. [ In particular, it is preferable that the illuminating device 20 is operated only when there is an impact of a certain intensity or more on the vehicle under a certain illuminance according to the sensing signal of the illuminance sensor 11 and the sensing signal of the impact sensor 12. [

In addition, GPS (Global Positioning System) is incorporated in the black box 10 for a vehicle according to the present invention to receive position information, time information, and the like.

The cloud computing server 30 is connected to a communication device 19 of a plurality of vehicle black boxes 10 via a mobile communication network to transmit / receive various data and to store received data. The cloud computing server 30 provides a computing service, a storage service, a communication service, and an infrastructure service management to a service user, that is, a vehicle black box 10. It is preferable that the cloud computing server 30 provide both a black box 10 for a vehicle to be connected and a browser used in the mobile terminal 40, that is, an iOS, an Android, or a PC based browser.

The mobile terminal 40 is preferably a mobile communication terminal such as a smart phone, and includes a PC such as a tablet or a notebook having improved mobility. The mobile terminal 40 is provided with an application 41 for a black box image data service. The mobile terminal 40 includes a GIS (Geographic Information System) 42 including a map for displaying geographical information. Furthermore, it is preferable that the vehicle black box 10 is basically provided with a GPS for recognizing the geographical information.

The video data and the GIS interworking service method of the vehicle black box according to the present invention will now be described with reference to the flowcharts of FIGS. 2 and 3. FIG.

2, when the vehicle is running or the black box 10 mounted on the vehicle is operated while the vehicle is parked or stopped regardless of whether or not the occupant is present in the vehicle, the photographing apparatus 18 is disposed in the vicinity of the vehicle, Channel), rear (2 channels), left room (3 channels) or right room (4 channels). The photographing range will vary depending on the number of channels of the photographing apparatus 18 mounted or connected to the vehicle black box 10 depending on the direction of the vehicle centering on the vehicle. Therefore, when a shock due to a collision, a collision, or the like occurs in the front, rear, or side of the vehicle while photographing the surroundings of the vehicle in the photographing apparatus 18 mounted on the vehicle black box 10, the impact sensor 12 detects the impact S2). At this time, the impact sensor 12 senses the set impact strength. The impact strength will be determined to the extent that the degree of impact on the vehicle is such that it can cause damage to the vehicle or damage to the driver or passenger on board. When the shock sensor 12 senses an impact of a certain intensity due to the detection of the illuminance sensor 11 according to the illuminance at night or the surroundings of the vehicle, the illumination device 20 according to the photographing direction of the photographing device 18 is operated It is good.

When the shock sensor 12 detects a certain level of impact, the controller 15 of the vehicle black box 10 edits the image data stored in the storage device 16 (S3). At this time, the control unit 15 also edits an image photographed for a predetermined time after the impact of the impact sensor 12 is sensed. That is, the control unit 15 edits the image data photographed for a predetermined time before and after the impact is applied to the vehicle from the outside. For example, the control unit 15 extracts image data of 10 seconds before the impact and 10 seconds after the shock from the image data stored in the storage unit 16, 10 still images are extracted. The time before and after the impact for editing the image data in the control unit 15 can be set in advance. The control unit 15 edits a still image, an impact image, and a post-impact image in the control unit 15, and the control unit 15 can set the number of still images at the time of impact and before and after the impact. Further, since the image data captured by the photographing apparatus 18 currently mounted on the vehicle shoots a full HD-level image at approximately 1,280 × 720 pixels (pixel) according to the sharpness and resolution, the control unit 15 When editing, the resolution of the extracted image is converted into approximately 320 × 240 pixels. This is because the full HD video data has a large capacity and takes a long time to be transferred. Therefore, it is advantageous to reduce the time required for the transmission of the reduced resolution image.

The control unit 15 accesses the communication network through the communication device 19 of the vehicle black box 10 and connects to the specified cloud computing server 30. [ And accesses the cloud computing server 30 and performs an authentication procedure (S4). The authentication procedure of the vehicle black box 10 and the cloud computing server 30 is for distinguishing whether the vehicle black box 10 connected to the cloud computing server 30 is a device registered for transmitting and receiving image data or the like . The controller 15 accesses and authenticates the cloud computing server 30 and transmits the location information, the time information, and the receiver information of the vehicle together with the edited image data in the controller 15 (S5). The location information of the vehicle can be used to easily grasp the position of the vehicle. The time information can be used to determine a time point depending on an external impact, and the receiver information is transmitted to the cloud computing server 30, And a telephone number for transmitting to the recipient's mobile terminal via the Internet.

The cloud computing server 30 stores the image data, the location information, the time information, and the receiver information received from the control unit 15 of the vehicle black box 10 (S6). Then, the cloud computing server 30 transmits an alarm informing the recipient's mobile terminal to confirm the image data from the stored recipient information (S7). That is, when the image data including the receiver information is received from the vehicle-use black box 10, the cloud computing server 30 sends a message to the receiver to confirm that the image data is received and stored in the cloud computing server 30 (Alram) containing the alarm.

Accordingly, after receiving the alarm from the cloud computing server 30 from the mobile terminal 40, the receiver executes the black box image data service application 41 (S8). It is preferable that the black box image data service application 41 installed in the recipient's mobile terminal 40 is automatically executed when an alarm is received in the cloud computing server 30. [

When the black box image data service application 41 is executed, the mobile terminal 40 accesses the cloud computing server 30 via the communication network and performs a recipient authentication procedure (S9). Then, the mobile terminal 40 allows the receiver to determine whether to check the image data after connection and authentication with the cloud computing server 30 (S10).

The mobile terminal 40 can be configured to input the key or the icon displayed on the screen in order to confirm the image data through the application 41. [ When the image data is confirmed, the mobile terminal 40 receives and stores the image data stored in the cloud computing server 30 (S11). Further, when the reception of the image data is completed (S12), the mobile terminal 40 causes the image data stored in the cloud computing server 30 to be deleted (S13). This is to reduce the load according to the storage capacity of the cloud computing server 30.

The mobile terminal 40 interlocks the received image data with the built-in GIS (Geographic Information System) 42 to display the image data together with the geographical information on the screen of the mobile terminal 40 (S14). That is, after the GIS 42 is executed, the mobile terminal 40 displays location information included in the received image data in the geographical information to display the location of the vehicle, and displays the corresponding image data, that is, a moving image or a still image . Therefore, the receiver can confirm the situation of the collision or collision of the vehicle in real time through the mobile terminal 40, so that quick post-treatment can be performed.

In addition, according to the settings of the control unit 15 and the cloud computing server 30 of the vehicle black box 10, image data can be set to be transmitted not only to the receiver but also to the car accident insurance company, the traffic controller or the police station. Furthermore, it may be possible to set up such a system to transmit a safety accident caused by a collision or a collision to a public vehicle or a freight vehicle such as a bus or a taxi to an affiliated company, a government office or a traffic controller.

3, the photographing state of the photographing device 18 installed in the vehicle black box 10 at the mobile terminal 40 can be confirmed. The mobile terminal 40 connects to the communication device 19 of the black box 10 via the communication network after the black box image data service application 41 installed in the mobile terminal 40 is executed (S21) S22). Then, authentication is performed with the control unit 15 of the mobile terminal 40 and the black box 10 (S23). When authentication is performed, the mobile terminal 40 selects any one of a plurality of photographing apparatuses connected to the vehicle black box 10 through an application executed in the mobile terminal 40 (S24). That is, the photographing device 18 installed at the front, the rear, or the side of the vehicle black box 10 can be selected to confirm the current photographing state.

Accordingly, it is possible to select and confirm the image data around the vehicle currently photographed by the mobile terminal 40 or the image data stored in the storage device after the image is photographed (S25). The control unit 15 of the vehicle black box 10 displays the image data currently being photographed in the corresponding channel in real time by the selection of the mobile terminal 40 when the mobile terminal 40 selects the image currently being photographed on the channel (S26). The control unit 15 of the vehicle black box 10 selects the image that the mobile terminal 40 has already photographed on the channel and selects the image on the corresponding channel by the selection of the mobile terminal 40, The stored image data is transmitted in real time (S27). Therefore, the mobile terminal 40 displays the image data received from the vehicle black box 10 together with the GIS (Geographic Information System) 42 installed in the mobile terminal 40 together with the geographical information on the screen (S28).

When the user selects to delete the image data stored in the storage device 16 of the vehicle black box 10 through the black box image data service application 41 executed in the mobile terminal 40 (S29) The image data stored in the memory 16 can be deleted (S30). This may be performed to empty the storage capacity of the storage device 16 or to remove unnecessary image data, and selectively delete only necessary portions.

When downloading of the image data stored in the storage device 16 of the vehicle black box 10 is selected through the black box image data service application 41 executed in the mobile terminal 40 (S31) The image data stored in the mobile terminal 16 can be downloaded to the mobile terminal 40 and stored (S32). This is to allow the user to download and store important video data that needs to be stored or utilized.

As described above, according to the present invention, when an impact of a predetermined intensity or more is exerted on a vehicle that is being driven or parked or stopped, the image data captured by at least one photographing device installed in a black box for a vehicle before and after the impact time, So that the receiver can check the surrounding images of the vehicle in real time, so that it is possible to follow up the safety accident, and in particular, when the vehicle is parked remotely from the vehicle driver, It is possible to implement the measures quickly, thereby improving the safety and safety of the vehicle black box as well as improving the reliability of the vehicle.
