The black box power supply 300 can exchange data with each other through a communication object.

The dual battery unit 310 can be charged by receiving power from the vehicle. At this time, the dual battery unit 310 may include at least two batteries, and even if the capacities of the two batteries are different, the dual battery unit 310 may be configured such that the total amount is consumed while maintaining the same voltage. Also, the dual battery part 310 can be detached from the black box power supply 300 through a slot formed in the black box power supply 300. [

The control unit 320 measures the potential of the power source supplied from the vehicle and outputs a control signal to the black box connected to the black box power supply device 300 from the dual battery unit 310 100 to be supplied with power. That is, the control unit 320 logs and measures the time when the potential value of the dual battery unit 310 is lower than a preset reference value, and measures the usage time and the amount of power of the dual battery unit 310, ), And output the log when the measured data exceeds the available data. Here, the supplyable data may be available time and power amount.

Meanwhile, the dual battery unit 310 may be charged with the power supplied through the power supply unit 350 of the black box 100. That is, the dual battery unit 310 can be charged with the power supplied through the power supply unit 350, and after the charging, the charging can be stopped for overcharge protection, The black box 100 can be powered. At this time, the battery of the dual battery unit 310 can be detachably attached to the slot-shaped groove. Here, the battery of the dual battery unit 310 is a detachable battery. When the use of the dual battery unit 310 is completed, the battery can be replaced with another battery. The capacity of the battery of the dual battery unit 310 is determined. However, in the case where the black box 100 of the dual battery unit 310 determines how much power is used for a few hours when the battery of the vehicle is not charged It is possible to inform the user terminal of the purchase of the battery having the capacity corresponding to the pattern and to change the capacity to the user terminal or replace the battery with a new battery even when the life of the battery is shortened You can tell.

In summary, the black box power supply apparatus 300 monitors the amount of power supplied to the power supply unit 350, and controls the dual battery unit 310 to supply power when the monitored amount of supplied power is less than a preset amount of power . In other words, when the battery of the vehicle, the battery of the black box power supply device 300 is another battery, and the vehicle is not in operation, the battery is not charged due to the running of the vehicle, When the battery of the vehicle is used, the battery of the vehicle may be discharged and the starting may not take place. Therefore, the black box power supply 300 prevents the black box 100 from consuming the battery of the vehicle when the battery of the vehicle is consumed and the battery of the vehicle is kept below the predetermined potential value, Thereby powering the box 100. Then, the black box power supply 300 may pattern the time when the vehicle is stopped, etc., and analyze what capacity of the battery is required to be recognized by the user. Alternatively, the black box power supply 300 may send an alarm for battery replacement to the user terminal. The control unit 320 may supply power to the dual battery unit 310 from the battery of the vehicle through the power supply unit 350 when the measured potential value from the battery of the vehicle is equal to or greater than a preset potential value.

3, the connection management unit 360 includes at least one LED 361, at least one USB interface 362, an output terminal 363, an input terminal 364, and a power terminal 365 .

In this case, the parallel can be based on the vertical axis or the horizontal axis. That is, they may be parallel based on all of the X, Y, and Z axes.

In addition, the black box power supply 300 may form a communication interface for interlocking with the black box 100 and the user terminal. When the content stored in the black box 100 is connected to the black box 100 in a wireless or wired manner, the black box power supply 300 may transmit a 10 G black box, for example, The content may be moved to the black box power supply 300 or a storage location of the black box 100 may be the black box power supply 300 in order to secure memory. At this time, in addition to considering computing resources and networking resources, when the stored content is transferred or uploaded to an account connected to the user terminal, the black box power supply 300 may transmit abnormal data connected to the stored frame, The content can be removed and uploaded. In other words, there is no accident or everyday content is often not needed later. At this time, the impact data can be received by being connected with an ECU (Electronic Control Unit) of the vehicle, and a method of confirming whether or not the abnormal data can be obtained can be performed through comparison and analysis of image templates.

In addition, the black box power supply 300 can receive and store an image photographed by the black box 100 through the wireless communication unit 310. [ At this time, when the image is stored, if the content does not have the above-mentioned abnormal data, the size of the data may be reduced by decreasing the resolution of the data, for example. In addition, the storage unit 320 adjusts the resolution of the pre-stored content or moves the content to the account connected to the user terminal when the predetermined percentage is exceeded in consideration of the ratio of the user's own capacity and the stored capacity Can be adjusted.

Here, the black box power supply 300 includes a SSD of a hard disk drive (HDD), and includes a temperature measuring sensor (not shown) for measuring the temperature of the HDD and a temperature measuring sensor And may further include a cooling fan (not shown) for cooling the HDD when it is exceeded. Here, the HDD is an auxiliary storage device of a computer which is nonvolatile, sequential access. Rotate the platter in the protective case and record information on it in a magnetic pattern. Here, the device for driving the platters is formed of a spindle motor. Data is written to the magnetic body coated on the platter surface and can be magnetically written and read by the input / output head floating above the rotating platter. However, since the CPU and the RAM are semiconductor materials that perform data processing only by the movement of electrons moving between the microcircuits, the HDD can operate at a high speed. However, the HDD physically rotates the magnetic disk as a platter and reads or stores data, No matter how fast you spin the magnetic disk, you can not keep up with the speed of the semiconductor. Thus, according to one embodiment, the HDD may be implemented as an SSD, wherein the SSD (solid state drive) stores data using a semiconductor rather than a magnetic disk. Because of these characteristics, SSDs can read or write data faster than HDDs. And since there are no physically moving parts, there is no operating noise and power consumption is low. This is only an example, and it will be obvious that the implementation of the storage device in the HDD is not limited.

The black box power supply 300 can upload images stored in the black box power supply 300 in real time in the cloud associated with the account of the user terminal. Here, even if the user terminal does not separately register the account, if the user terminal is paired with one authentication, the user's account information is extracted, and the account having the largest capacity of the drive among the extracted account information is selectively You can choose.
