Hereinafter, the configuration of each part of the vehicle driving information recording apparatus according to the present invention in more detail.

First, the control panel 110 provided in the housing 10 includes a microcomputer 112 for the overall control and an image processor for processing images captured by the first and second cameras 102 and 104. And a voice processor 116 for processing voice of the microphone 134 or speaker 146, and a basic memory unit 118 for storing driving programs.

At this time, the basic memory unit 118 is naturally composed of a ROM area for storing the drive program, and a RAM area for temporarily storing data when the program is driven.

On the other hand, the microcomputer 112 is initialized when the power is supplied through the power connection unit 122 to monitor the event state, by pressing the reset button 120 provided on one side of the housing 10, it is natural that the initialization is natural At the same time, it monitors whether a certain event state is present.

In this case, the specific event is divided into an emergency event generated when the user sets arbitrarily, a shock event generated due to a collision of a vehicle, and a speed event due to speeding, sudden braking, or sudden start of the vehicle.

The emergency event is an event generated when the emergency button 128 provided on the surface of the housing 10 or the external button 140 connected to the external button connecting portion 144 of the housing 10 is pressed. The external button 140 is preferably attached to the lower portion of the instrument panel on the front of the vehicle driver's seat for easy driver operation.

When such an emergency button 128 or an external button 140 is pressed, the microcomputer 112 of the control panel 110 is recognized as an emergency event, for example, an emergency button 128 or an external button 140. On the basis of the pressed time point, the image of the previous 10 seconds to the next 10 seconds is separately stored in the data storage memory 136 as event data.

Of course, the storage time at the time of occurrence of the event is just an example and can be arbitrarily set as necessary.

On the other hand, the shock event is an event by the impact detection signal of the shock sensor 148 provided in the housing 10, even when such an impact event is detected, the microcomputer 112 of the control panel 110 Recognizes as an emergency event, and stores the image of the previous 10 seconds to 10 seconds after the event time in the data storage memory 136 separately as an event data.

In addition, the speed event is converted into speed data using GPS reception information input through one side of the GPS connection unit 106 of the housing 10, and the speed event is used when the speed is faster than the road condition, and the sudden driving speed is reduced. The presence or absence of an event can be determined by classifying a case of sudden braking and a case of sudden starting due to a sudden increase in driving speed.

Even when such a speed event is detected, the microcomputer 112 of the control panel 110 recognizes the speed event and separately stores an image between the previous 10 seconds and the next 10 seconds based on the time of the speed event. 136 is stored as event data.

On the other hand, the inside of the housing 10 is further provided with a charging unit 119 for charging the power supplied through the power connection portion 122 to be driven independently even when the power supply is stopped due to the battery of the car. Can be.

In this case, a cigar jack connection terminal 123a for receiving power through the power supply cigar jack 123 is connected to the power connection unit 122.

In this case, when the allowable voltage (for example, 10.5V) or less of the power supply through the power supply cigar jack 123 is lower, the power supplied through the power supply cigar jack 123 is cut off and the power of the charging unit 119 is turned off. In order to use the voltage sensing unit 121 is further provided.

Therefore, when the start-up is turned off due to the parking or stopping of the vehicle by such a configuration, the voltage detecting unit 121 checks the supply power periodically to check whether the reference voltage is below the reference allowable voltage, and when the voltage is exceeded. When the power is supplied and operated, and the supply voltage detected by the voltage sensing unit 121 is less than the allowable voltage, the power supply of the car battery is cut off and the power is continuously supplied by the charging unit 119. When all of the power of 119) is exhausted, the vehicle is automatically stopped. Therefore, it is possible to monitor and store the driving information around the car for a long time.

On the other hand, in the case of night time, the first and second cameras 102 and 104 may not properly secure images. To this end, the illuminance sensor 124 provided on the surface of the housing 10 detects whether illuminance is less than or equal to the set illuminance. In this case, when the illuminance is less than or equal to the set illuminance, the microcomputer 112 displays the infrared image of the second camera 104. The infrared LED 126 is turned on so that the image can be photographed to irradiate the infrared light, and thus the infrared light is reflected from the object so that the image can be captured even in a place where there is no light.

On the other hand, the data storage memory 136 is inserted into the memory insertion unit 138 or can be separated as necessary, using a known memory card. In this case, since the memory card has various types of cards, detailed description thereof will be omitted.

In addition, the monitor connection unit 108 is connected to a monitor 109 installed inside the vehicle. Therefore, the images captured by the first and second cameras 102 and 104 are displayed on the monitor 109 in real time.

On the other hand, the first camera 102 is installed to face the front of the car, the second camera 104 is installed to face the interior of the car, so that the inside and outside of the car through the first and second cameras (102, 104) You can shoot at the same time.

In this case, the internal and external images of the vehicle photographed by the first and second cameras 102 and 104 are continuously stored in the data storage memory 123.

When a specific event occurs in this state, the previous image within 10 seconds before the specific event occurs and the image after 10 seconds taken after the specific event occur are separately stored in the data storage memory 136 as event data. Done.

On the other hand, when the capacity of the data storage memory 136 is insufficient or when the set time (for example, 2 hours) has elapsed, the event data is stored, and the image data that is continuously taken is deleted in such a manner as to delete the image data. Manage the capacity of 136.

In addition, the vehicle driving information recording apparatus 1 further includes an infrared sensor 117 capable of detecting a distance of about 5 meters so that the microcomputer 112 determines when an unspecified person approaches the vehicle while the driving of the vehicle is stopped. Recognized as an event, the previous image within 10 seconds before the specific event and the subsequent image captured within 10 seconds after the specific event occurs are stored separately as event data in the memory 136.

Hereinafter, an operation process of the driving information recording apparatus for a vehicle according to the present invention will be described in detail.

First, after installing the driving information recording device for the vehicle in front of the interior of the car, connecting the GPS receiver 105 and the monitor 109, and connecting the power supply cigar jack 123, recording the driving information for the automobile The device 1 is initialized and driven and a beep sound is output through the speaker 146.

When the vehicle is driven in such a state, images captured by the first and second cameras 102 and 104 are processed through the image processing unit 114 and continuously stored in the data storage memory 136, in this case, the microphone. The voice information input through 134 is also processed by the voice processor 116 and continuously stored in the data storage memory 136 together with the image.

In such a state, the microcomputer 112 calculates the speed by using the position information and the time difference received through the GPS receiver 105, and a speed event in which the speed is determined to be a state of overspeed, sudden drop or oscillation, and the user arbitrarily emerges. It is checked whether an emergency event when a button or the like is pressed and a shock event by a shock detection signal of the shock detection sensor 148 are detected due to a collision of a vehicle.

In this case, when a specific event occurs and the microcomputer 112 detects this, the previous image during the previous time (within 10 seconds) before the occurrence of the specific event and during the time after shooting after the occurrence of the specific event (within 10 seconds) After that, the image is stored in the data storage memory 136 as event data.

In particular, when storing the event data including the previous image and the subsequent image in the data storage memory 136, it is possible to secure the objective evidence by storing the driving speed, position, and time of the vehicle at the time of occurrence of the event. Let's do it.

Meanwhile, images captured by the first and second cameras 102 and 104 are continuously stored in the data storage memory 136 and displayed on the monitor 109 in real time.
