DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The file stored in the black box memory card is a video file, and the size of the encoded file is very large. Therefore, when a black box for a vehicle is normally recorded, a moving picture file is generated every minute, so writing to a memory card (or a storage medium) such as an SD card frequently occurs. In addition, the video stored and judged as an important event in the black box itself is not important to the user, and frequent memory card writing may occur due to the occurrence of an event having a high positive error rate. As described above, when moving picture files of a relatively large capacity are frequently written to the memory card, the remaining capacity of the memory card is lost due to the capacity limitation of the memory card. Therefore, when storing a new moving picture file, Is required. That is, there is a problem of file overwriting according to the limited capacity of the black box.

Accordingly, in order to securely store the file stored in the memory card for a long period of time, the user has to store the memory card of the black box in a separate place.

When file overwriting is executed, the selection criteria of the file to be deleted is generally the oldest file created before. In other words, the criterion for determining the importance of the file is to consider only the recency of the file, which is a measure indicating how recently the file is formed.

However, if the importance of the file is determined only by the recentness of the file, and the overwrite is performed from the oldest file, the file overwrite can be performed only because the important file stored in the state exposed to the dangerous situation is the oldest file. And can be deleted as a target.

Therefore, the importance of the file should be reflected not only in the last name, but also the risk of the situation in which the image is recorded. That is, the importance of the file should be calculated considering both the generation time of the file (that is, the recentness) and the risk, and the file overwriting should be executed in order of the lowest importance file by judging the importance of the file.

1 is a block diagram illustrating a storage area of a storage medium according to an embodiment of the present invention.

Referring to FIG. 1, a method of dividing a storage area of the storage medium is not limited thereto. However, the method of dividing the storage area of the storage medium includes the normal recording storage unit 110, the parking motion storage unit 120, the normal impact storage unit 130, A recording unit 140, and a manual recording / storing unit 150.

First, the normal recording storage unit 110 is a storage area in which a moving picture file can be continuously stored in a running state of the vehicle. Therefore, the normal recording / storing unit 110 stores a file in units of a predetermined time at the time of driving. For example, it is possible to set the moving picture file for one minute to be continuously stored.

The parking motion storage unit 120 is a storage area in which a moving picture file can be stored when a motion is detected while the vehicle is parked. For example, when motion is detected during parking, it is possible to set an image for 30 seconds before and after the motion is detected to be stored in a file.

In addition, the constant impact storage unit 130 is a storage area in which a moving image file can be stored when an impact such as an external shock applied to the vehicle or a sudden braking of the vehicle occurs. Therefore, it is possible to set, for example, a one-minute image in which an impact occurs, to be copied and stored in a space where an image when the rate of change of the acceleration sensor value is higher than a threshold is stored.

The parking impact storage unit 140 is a storage area in which a moving picture file can be stored when the rate of change of the acceleration sensor value is higher than a threshold when the vehicle is parked. For example, when the change rate of the acceleration sensor value at the time of parking is higher than the threshold, it is possible to set an image for 30 seconds before and after it to be stored as a file.

Lastly, the manual recording storage unit 150 is a storage area in which a moving picture file can be stored according to manual recording of the user. Accordingly, it is possible to set an image for 30 seconds before and after the point at which the button is pressed for manually recording by the user.

When the file is stored in each storage area, the time when the file is created, the rate of change of the acceleration sensor value, the position coordinates of the vehicle or the moving speed of the vehicle related to whether or not the vehicle is exposed to the dangerous area from the GPS coordinates, The kind or size of the sound generated in the parking lot, and whether or not the motion is detected during the parking, can be stored in the storage medium.

Therefore, a storage medium such as a memory card mounted on a vehicle black box is distributed to a storage area of a storage medium according to characteristics of a storage image, thereby managing the file according to the importance of the storage medium.

Here, importance of a file refers to the importance of a file as a single value or a value, so that the larger the value, the more important it is.

As described above, the importance level of the file can be determined by classifying the importance level item as follows and calculating the importance degree by simple calculation.

(Example 1)

In the first embodiment, the Importance factor (I) of the file can be calculated through a weighting function f (function) of the following sensor values.

Table 1 shows importance items for determining importance of files according to an embodiment of the present invention.

Importance Items Detail Φ Items related to acceleration sensor values ρ Items related to the size of the sound when the car is exposed ε Items related to the type of sound when the car is exposed σ Items related to the position coordinates of the vehicle beta Items related to the moving speed of the vehicle δ Items related to whether or not ACC signals related to whether the vehicle is traveling or parked θ Items related to whether the user's intention is reflected τ Items related to file creation time

Thus, referring to Table 1, the importance of the file is related to the acceleration sensor value, the size of the sound generated when the vehicle is exposed, the type of sound generated when the vehicle is exposed, , Items related to the position coordinates of the vehicle, items related to the moving speed of the vehicle, items related to whether or not the ACC signal related to whether the vehicle is running or parked, items related to the user's intention to reflect the user's intention, , And the importance (I) of the file can be expressed through a weighting function of each sensor value.

(Example 2)

In Embodiment 2, the Importance factor (I) of the file can be expressed by the following equation.

Table 2 shows the importance items for determining the importance of the file according to the second embodiment.

Importance Items Detail R (recency) The more recently saved the file, the higher the value assigned

(accelerometer) Peak change rate of acceleration sensor value D (danger) Vehicle Exposure Risks in Video-Recorded Environment Based on GPS Information M (motion) When parking, it assigns a value to a stored image due to motion detection U (user saving) When the user specially intentionally saves the image, the value assignment

Referring to Table 2, the importance level of the file is R (recency)

(accelerometer), D (danger), M (motion). And user saving (U). Firstly, it shows the recent recorded image of the file as R (recency) and indicates the peak change rate of the acceleration sensor value related to the external shock applied to the vehicle or sudden braking of the vehicle

(accelerometer). In addition, the vehicle exposure can be expressed as D (danger) for the accident bundle area or the speed violation control area obtained from the GPS, and the image stored by the motion detection during parking can be expressed as M (motion). Lastly, it is possible to distinguish importance items by indicating user's recording intention by U (user saving).

Table 3 shows the weights according to the importance of the files.

Weight Detail alpha The weight of the file's recency beta The weight of the peak acceleration rate of the file gamma Weight of vehicle exposure risk δ Weight for motion detection ε Weight for manual recording

Table 3 shows the weights according to the importance level of the files. The weights can be expressed as α, β, γ, δ, and ε according to each importance level item.

Therefore, the importance (I) of the file according to the second embodiment can be represented as the sum of the weighting factors applied to the respective importance items.

Here, the service provider and the user can add or change various items such as the risk judgment item by the sound sensor to the importance item of the file, and the value of the weight can be changed according to the appropriate environment and intention.

2 is a flowchart illustrating file management according to importance in a storage area according to an embodiment of the present invention.

Referring to FIG. 2, a file having the lowest Importance factor of each file in each storage area may be overwritten.

Step 201 may open a new file for storage on the storage medium and start writing to the storage medium.

In step 202, an empty space in which a new file can be stored can be confirmed in the storage area of the storage medium.

Step 203 may store a new file in the empty space if the empty space is confirmed in the storage area of the storage medium.

In step 204, if a vacant space in which the new file can be stored is not confirmed in the storage area of the storage medium, the file having the lowest importance in the storage area can be searched.

Step 205 may overwrite (overwrite) the file having the lowest importance in the storage medium with a new file.

If the vacant space is not confirmed in the storage area, a file having the lowest importance is searched for in the storage area. The importance is determined based on the peak change rate information of the acceleration sensor value It is possible to determine the importance or to determine the importance based on GPS (Global Positioning System) position information.

The determination of the importance may be made based on the generation time information of the file, the acceleration sensor information, the GPS position information, the moving speed of the vehicle, the motion detection information, the sound information, the user storage information, The importance of the file can be determined by a value calculated by applying the weight to each piece of information. At this time, in order to determine the importance of the file, information such as recentness, acceleration, exposure risk, motion detection, and user storage is obtained according to the importance item of the file by using a sensor or the like, Can be used.

For example, when a new file A is opened and is started to be written to the memory card, it is checked whether there is a vacant space in the storage area of the memory card. At this time, when the empty space is confirmed in the storage area, the writing of the new file A can be completed. However, if the storage area is filled with files and the empty space can not be checked, it is possible to replace the file B having the lowest importance among the entire files filling the storage area with the new file A have.

3 is a flowchart illustrating file management according to importance of storage areas of a storage medium according to an embodiment of the present invention.

Referring to FIG. 3, step 301 may open a new file for storage on a storage medium and start writing to the storage medium.

In step 302, an empty space in which a new file can be stored can be confirmed in the storage area of the storage medium.

Step 303 is to store a new file in the empty space if the empty space is confirmed in the storage area of the storage medium.

In step 304, if a vacant space in which the new file can be stored is not confirmed in the storage area of the storage medium, the file having the lowest importance in the storage area can be searched.

Step 305 may delete the lowest importance file from the storage medium and overwrite it with the new file.

If the vacant space is not confirmed within the storage area, a file having the lowest importance is searched for in the storage area. The importance is determined by measuring the peak change rate information of the acceleration sensor value, the GPS (Global Positioning System) position information, information on at least one of a moving speed of a vehicle, a motion sensor, an acoustic sensor, and a user button, and calculates a value obtained by applying a weight to each of the information The importance of the file can be determined. At this time, the information is a weight item and a weight value as described above, and the type thereof may be determined by the user and the service provider.

In step 306, overwriting is performed by replacing the file having the lowest importance with the new file to overwrite the file. Thus, it is possible to check whether the file is empty or not in another storage area of the storage medium.

Step 307 may store the overwritten file in the previous storage area in the empty space when the empty space is confirmed in the other storage area.

Step 308 is to check whether there is an empty space in another storage area of the storage medium and to search for a file having the lowest importance in the other storage area if the empty space is not confirmed in the other storage area can do.

Step 309 may determine whether the file having the lowest importance in the other storage area is less important than the file overwritten in the previous storage area.

If the file having the lowest importance in the other storage area is less important than the file overwritten in the previous storage area, the file having the lowest importance in the other storage area is stored in the overwritten file Alternatively, it can be overwritten.

For example, over-writing may occur due to capacity limitations of the parking motion area, in general, when parking in long-term parking or in a place where movement is very frequent. On the other hand, the normal recording area is generally allocated the largest amount of capacity, and is not used in the parking mode. Therefore, if the file overwritten from the parking motion storage area and subjected to deletion is of high importance, it is possible to back up the file having high importance to the always-recording storage area.

That is, if there is a file B which is overwritten from the parking motion area and which is subject to deletion, the B file can be backed up to the normal recording area if there is a vacant space that can be stored in the normal recording area. However, if there is no empty space that can be stored in the normal recording area, the file C having the least importance among the entire files stored in the normal recording area can be replaced with the file B. However, it is possible only when the importance degree of the file C is lower than the importance degree of the file B.

In addition, the controller 430 may check a vacant space in the storage unit and store a new file in the storage unit 430 when a vacant space is confirmed. If the vacant space is not confirmed in the storage unit, the storage unit 430 searches for the lowest-importance file, overwrites the lowest-importance file with the new file, ). &Lt; / RTI >
