Description

[0001] DRIVING VIDEO RECORDER AND METHOD THEREOF [0002]

The present invention relates to a traveling image recording apparatus and method, and more particularly, to a traveling image recording apparatus capable of ensuring that a traveling image is recorded securely and extending the service life of a nonvolatile memory used for recording a traveling image And methods.

[0002] Recently, a driving image recording apparatus, that is, a black box, which detects and records all the information generated in a vehicle in the event of an accident or an accident, is gradually increasing in the vehicle.

The black box stores the driving image in a removable external memory so that the recorded image can be reproduced on a user device such as a notebook PC, a mobile phone, a navigation device, a MP3 player, a PMP, or the like. However, when a physical or logical error occurs in the external memory, an accident image is not recorded, and there is no way to restore it.

In addition, the SD card, which is mainly used as an external memory, has a problem in that data is repeatedly written and erased from time to time due to the characteristics of the black box, so that the life is shortened and replacement is required every time the life cycle comes.

Accordingly, there is a need for a traveling image recording apparatus that can extend the life of an external memory by storing the traveling image in the external memory only when the reliability of data storage is improved and when an accident actually occurs.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

1 is a block diagram for explaining a running recorder according to an embodiment of the present invention.

Only the components related to the present embodiment are shown in the running-image recording apparatus 100 shown in Fig. Therefore, those skilled in the art will recognize that other general-purpose components other than the components shown in FIG. 1 may be further included.

The running image recording apparatus 100 shown in FIG. 1 may be a black box for a vehicle (an event data recorder for an automobile), but is not limited thereto. Hereinafter, for the sake of convenience of explanation, it is assumed that the running video recording apparatus 100 is a vehicle black box.

1 includes a battery 110, a volatile memory 120, a real-time recording unit 130, a non-volatile memory 140, an event sensing unit 150, and an event processing unit 160 .

The battery 110 supplies power to drive the driving video recording apparatus 100 even when the driving video recording apparatus 100 is disconnected from an external power supply (not shown). Therefore, even when the volatile memory 120 is disconnected from the external power source, the power can be supplied for a certain period of time and the data stored in the volatile memory 120 can be maintained. The battery 110 may be installed in the traveling image recording apparatus 100. When the traveling image recording apparatus 100 is charged in a state of being connected to an external power source and the traveling image recording apparatus 100 is disconnected from the external power source, And the like.

The volatile memory 120 may allocate a certain area to a RAM-disk, and the vehicle driving image data is recorded in a streaming form.

Here, a RAM-disk means that an extra unused storage space of the capacity of the RAM, which is a volatile memory, is used as if it is a disk. For example, some space in RAM (RAM) is utilized as an auxiliary storage device such as a hard disk or a floppy disk in a hardware or software manner.

Volatile memory 120 such that a non-volatile memory 140 such as a flash memory or an external hard disk drive is normally stored in the ramdisk, When the running image is linked to the nonvolatile memory 140, it is possible to utilize both the characteristics of the RAM having a high processing speed and the characteristics of the auxiliary storage device having a large storage space.

The real-time recording unit 130 receives vehicle driving image data and records the same in the volatile memory 120 in real time.

The real-time recording unit 130 receives image data from at least one photographing unit (not shown) installed inside or outside the vehicle and photographs a vehicle traveling image, and records the received image data in the volatile memory 120. The real-time recording unit 130 may be implemented to be stored in an addressable storage medium to execute at least one processor. Accordingly, the real-time recording unit 130 may include software components, object-oriented software components, and class components.

The nonvolatile memory 140 is a storage medium in which driving image data is stored, and the stored contents are not lost even when the driving video recording apparatus 100 is powered off. The nonvolatile memory 140 may be embodied in the traveling image recording apparatus 100 or may be connected to the traveling image recording apparatus 100 in a separate configuration.

The nonvolatile memory 140, which is implemented as a flash memory such as a hard disk drive, an SD card, or a USB memory, stores various data for operating the traveling video recording apparatus 100, a program that implements an algorithm, And audio data for the audio data.

The event detection unit 150 detects a preset event occurring when a vehicle is impacted and records a vehicle drive image data recorded in the RAM disk in the nonvolatile memory 140 when an event is detected .

Volatile memory 140. The event processor 160 determines whether the data write to the non-volatile memory 140 is normal or not in response to receiving the write command from the event detector 150. As a result, At least a part of the vehicle driving image data recorded in the RAM disk 120 is recorded in the nonvolatile memory 140. [

When the event sensing unit 150 detects a predetermined event, for example, an amount of impact equal to or greater than a threshold value, the event processing unit 160 transmits the driving image data stored in the RAM disk 120 to the nonvolatile memory 140 to determine whether or not the nonvolatile memory 140 is normally connected to the running video recording apparatus 100.

If it is determined that the traveling image data can be normally recorded in the nonvolatile memory 140, the image recorded in the RAM disk is recorded in the nonvolatile memory 140. [ In this manner, instead of recording the running image data directly in the nonvolatile memory 140, the running image data recorded in the volatile memory 120 is stored in the ramdisk, and when it is determined that the nonvolatile memory 140 is normally connected It is possible to avoid the case where traveling image data is not stored due to a physical or logical error generated in the nonvolatile memory 140. [

In addition, the event detection unit 150 does not record the driving image data stored in the RAM disk in the nonvolatile memory 140 in all cases where the preset event is generated, and determines whether the generated event is an event caused by actual occurrence of an accident It is possible to generate a recording command for recording the traveling image data in the nonvolatile memory 140 only when it is determined that an actual accident has occurred.

Since the number of times data can be written to and erased from the nonvolatile memory 140 is determined, it is unnecessary to shorten the service life of the nonvolatile memory 140 by repeatedly writing and erasing a simple driving image instead of an accidental image in the nonvolatile memory 140 .

For example, when the vehicle passes the uneven portion, an amount of impact equal to or greater than a threshold value is applied to the vehicle. When the event sensing unit 150 generates a recording command corresponding thereto, Resulting in unnecessary shortening of the life of the memory 140. [

Accordingly, the event detection unit 150 according to the embodiment of the present invention receives the vehicle driving information, verifies whether the event occurrence is caused by an accident using the provided vehicle driving information, and determines that the event occurrence is caused by an accident A write command can be generated.

According to an embodiment of the present invention, the vehicle driving information may be provided through an OBD (On Board Diagnostic), and the vehicle driving information received through the OBD terminal may include fuel consumption, vehicle speed, RPM, Position, break state, and the like, and the event sensing unit 150 can use this information to determine whether an accident has occurred or not.

For example, when the vehicle speed is "0 km / h " or the engine revolution per minute is 0 for a certain period of time after the impulse amount exceeding the threshold value is applied to the vehicle, the event detection unit 150 determines that an accident has occurred. It is possible to generate a recording command for recording the traveling image data after the point of time when the impact amount is added from the previous point in time to the nonvolatile memory 140. [ In addition, when the running image data recorded on the RAM disk is recorded in the nonvolatile memory 140, it is possible to secure the space for recording the other data by deleting the running image data recorded on the RAM disk.

On the other hand, if it is determined that the vehicle has traveled normally after the impact amount exceeding the threshold value is applied to the vehicle, it is determined that the impact amount exceeding the threshold value is caused by an accident other than the accident and the image recorded on the RAM disk is stored in the nonvolatile memory 140 The recording command may not be generated.

As described above, if the running image data is recorded in the nonvolatile memory 140 only when it is determined that an actual accident has occurred, the normal running image, not the accident running image, is written to the nonvolatile memory 140 unnecessarily It is possible to prevent the life of the nonvolatile memory 140 from being shortened.

2 is a block diagram for explaining a traveling image recording apparatus 100 according to another embodiment of the present invention. Description of the configuration of the components shown in FIG. 2 that perform the same functions as those shown in FIG. 1 will be omitted.

The driving image recording apparatus 100 according to an embodiment of the present invention may include a communication unit 170 for transmitting the driving image data to an external device (not shown) instead of the nonvolatile memory 140 for recording driving image data have.

The event detection unit 150 may generate a transmission command for transmitting the vehicle driving image data stored in the RAM disk to an external device (not shown) when a predetermined event is detected.

The event processing unit 160 determines whether the communication unit 170 is normally connected to the external device in response to the transmission command generated by the event sensing unit 150. If the determination result communication unit 170 is normally connected to the external device Transmits at least a part of the vehicle driving image data recorded in the ram disk 120 to the external device.

The external device may be an external server that communicates with the running video recording device 100. However, the external device may be an external server that is connected to the running video recording device 100 by wire or wireless and can transmit and receive data, Lt; / RTI >

Meanwhile, the communication unit 170 may transmit data according to at least one e-Call standard among ETSI (European Telecommunications Standards Institute), CEN (European Committee for Standardization), and 3GPP (3rd Generation Partnership Project).

In this case, e-call means that when an accident occurs, an accident information sensor installed in the vehicle automatically or the passenger uses the manual button to transmit the accident information data including the accident occurrence position to the accident reception center, This is a series of processes for judging an accident situation by connecting a voice channel, and for preventing casualties and secondary accidents through prompt rescue after an accident.

3 is a conceptual diagram for explaining a traveling image recording apparatus 100 combined with an e-call according to an embodiment of the present invention.

As shown in FIG. 3, the running image recording apparatus 100 according to an embodiment of the present invention can be mounted on the vehicle 300 and record a real-time running image. When an impact amount equal to or greater than the threshold value is detected during the vehicle running, the communication unit 170 transmits the accident information data including the accident occurrence position to the accident reception center 320 using the mobile communication network 310. [ The accident reception center 320 that received the accident can use the received location information to carry out a series of procedures to prevent casualties and secondary accidents through quick rescue.

Meanwhile, if it is determined that the communication unit 170 is normally connected to the accident reception center 320 through the mobile communication network 310, the accident image data stored in the RAM disk may be transmitted to the outside. The incident image data to be transmitted at this time may be running image data about a certain time from the point of time when an impact amount exceeding the threshold value is applied.

As described above, if the e-call function is incorporated into the running video recording apparatus 100, it is possible not only to minimize the damage of the person through the rescue operation, but also to reduce the accident image stored in the RAM disk, which is a volatile memory, It is possible to achieve an effect that the reliability of data storage can be increased as the data is transmitted to the outside.

4 is a diagram illustrating a process of storing traveling image data according to an embodiment of the present invention.

The RAM disk 410 may be allocated to a part of the main memory 400 in a physical or software manner to store driving image data recorded by the real time recording unit 130. [ In a space other than that allocated to the RAM disk 410, a program for driving the running video recording apparatus 100 or data to be immediately referred to and executed by the CPU may be stored.

The size of the space allocated to the RAM disk 410 may be set by the user. The travel image recording apparatus 100 can store long traveling image data if the size of the space allocated to the RAM disk 410 is large. However, since there is a shortage of space for storing data to be immediately referred to and executed among programs and data stored in the ROM, The size of the space allocated to the RAM disk 410 becomes small, the size of the traveling image data that can be stored becomes small. On the other hand, since the traveling image recording apparatus 100 is accelerated, .

On the other hand, if the allotted RAM disk 410 is full, the oldest stored driving image data among the driving image data recorded in the RAM disk 410 is deleted and new driving image data can be recorded in the new space. If it is determined that the amount of the impact is greater than the threshold value while the data is being written to the RAM disk 410 and that the nonvolatile memory 140 is normally connected to the driving video recording apparatus 100, The forward and backward traveling image data at the time of being applied to the vehicle is recorded in the nonvolatile memory 140. [ In addition, only when the vehicle is subjected to an impact amount equal to or greater than the threshold value, the nonvolatile memory 140 is normally connected to the running video recording apparatus 100, and it is determined that the impact amount exceeding the threshold value is caused by an actual accident, The traveling image data may be stored in the nonvolatile memory 140. [

When the accidental image data is normally copied from the RAM disk to the nonvolatile memory 140, the corresponding image is deleted from the RAM disk, and a space for recording new data may be secured.

In the present embodiment, data is recorded in the main memory 400 as shown in FIG. 4 for ease of explanation. However, data may be stored in an arbitrary memory address by address designation.

5 is a view for explaining a method of storing a location where a predetermined event is generated by a vehicle impact according to an embodiment of the present invention.

The event detection unit 150 stores the location information of the event when the predetermined event occurs when the vehicle is impacted, and only when the event location information is not identical to the recorded location, Can be generated.

That is, when an event occurs in the pre-stored location information, it is determined that the vehicle is in a normal driving state and the vehicle driving image data recorded in the RAM disk may not be generated in the nonvolatile memory 140.

For example, it is possible that an event caused by an impact occurs every time a driver passes through a specific position in a state where the driver is traveling on the same route every day, due to the unevenness existing on the traveling route. If the vehicle is repeatedly applied with an impact amount exceeding the threshold value at the same position, the event sensing unit 150 may store the latitude and longitude information of the position where the impact amount exceeding the threshold value occurs. When a predetermined event is generated at the position stored in the running image recording apparatus 100, the controller determines that the vehicle is in a normal running state and does not generate a recording command for recording the traveling image data stored in the RAM disk in the nonvolatile memory 140 .

Alternatively, if an amount of an impact equal to or greater than a threshold value at a pre-stored position is applied to the vehicle, the event detection unit 150 can more strictly determine whether an accident has occurred. For example, if it is judged that an accident occurs when the speed is zero or the RPM is 0 or at least one of the rapid braking or the rapid acceleration has occurred after an impact amount equal to or greater than the threshold value is applied, It can be judged that an accident has occurred.

As described above, when a situation that may occur in the user's driving route is stored in advance to determine whether an accident has occurred, and when the driving image data is recorded in the nonvolatile memory 140, an unnecessary driving image is recorded in the nonvolatile memory 140 It is possible to achieve the effect of preventing the problem.

FIG. 6 is a flowchart illustrating a driving image recording method according to an embodiment of the present invention.

The vehicle driving image data received from the photographing unit is recorded in the volatile memory 120 (S610). When a predetermined event, for example, an impact amount exceeding a threshold value is detected during a vehicle running (S620), the vehicle driving image data recorded in the volatile memory 120 is stored in the RAM disk, and the nonvolatile memory 140 in step S630.

On the other hand, if the predetermined event is not detected, the driving image data is continuously stored in the volatile memory 120.

In response to the write command generated in step S630, the event processing unit 160 determines whether the data write to the nonvolatile memory 140 is normal or not (S630). If it is determined that the data write operation is normal, Vehicle driving image data recorded in the nonvolatile memory 140. [ On the other hand, if it is determined that data recording to the nonvolatile memory 140 is abnormal, the vehicle driving image data recorded in the RAM disk is maintained (S650).

On the other hand, the data recorded in the nonvolatile memory 140 among the vehicle driving image data recorded on the RAM disk can be deleted from the RAM disk 120.

As described above, only when the vehicle driving image data is stored in the RAM disk and the data can be normally recorded in the nonvolatile memory 140, the nonvolatile memory 140 It is possible to prevent the case where the vehicle driving image data is not stored due to physical or logical errors of the vehicle.

FIG. 7 is a flowchart illustrating a driving image recording method according to another embodiment of the present invention.

7 is recorded in the volatile memory 120 (S710), and the step of determining whether a preset event generated by the vehicle impact has occurred (S720) is the same as that described in Fig. 6 The same description will not be repeated.

When a predetermined event generated by the vehicle impact is detected, the vehicle driving image data recorded in the volatile memory 120 is stored in the RAM disk, and a transmission command for transmitting the data to the external device is generated. If it is determined that the communication unit 170 is properly connected to the external device (S740), the vehicle driving image data stored in the RAM disk is transmitted to the external device (S750). On the other hand, if it is determined that the communication unit 170 is not normally connected to the external device, the vehicle driving image data is stored in the RAM disk (S760).

That is, the reliability of data storage can be improved by storing the data in the RAM disk until the external device and the communication unit 170 are normally connected to transmit the vehicle driving image data.

Meanwhile, the above-described method can be implemented in a general-purpose digital computer that can be created as a program that can be executed by a computer and operates the program using a computer-readable recording medium. In addition, the structure of the data used in the above-described method can be recorded on a computer-readable recording medium through various means. The computer-readable recording medium includes a storage medium such as a magnetic storage medium (e.g., ROM, floppy disk, hard disk, etc.), optical reading medium (e.g., CD ROM,

Therefore, the disclosed methods should be considered from an illustrative point of view, not from a restrictive point of view.
