Description

Car DVR with Black Box Function {DVR (Digital Video Recorder) System including Use of the Black-box for the Auto-mobile}

The present invention relates to a car DVR including a black box function, wherein a driving state of a car, a collision during a car parking, a collision, a front or rear bumper or a side of another vehicle or a person by the front, rear, left, and right of the car are brought into contact with the car. In case of damage, the vehicle's accident situation storage and reading device using speed sensor, CCD camera or CMOS camera, sound sensor, shock sensor, contact sensor, etc. It is a technology that can save the situation information before and after a certain time from the time of the accident.

In the past, one solution was to cover skid marks or traffic laws in case of contact or collision accidents.In the event of an accident, the vehicle was photographed on the spot immediately or white spray paint was used. It has been taken to mark. In addition, the conventional automotive black box had to be equipped with a general camcorder or expensive equipment capable of storing information such as the speed at the time of driving the vehicle, the steering wheel bending, the position of the vehicle, and the like.

According to the present invention, when the vehicle is in contact with a bumper or side by another vehicle or person by collision, collision, collision, or when the vehicle is parked, or when the vehicle is in contact with the front, rear, left, and right of the vehicle, the information is recorded, It is possible to objectively determine the causes of traffic accidents by visually regenerating them during the accident analysis process, so that the vehicle can not only objectively determine the situation before and after the accident but also record and store minute accidents. To provide a black box function.

The present invention relates to a traffic accident such as a collision and a collision while driving a vehicle; About the car, such as when the car is parked; The situation around the car, such as impact, contact or breakage on the car; Charge-Coupled Device (CCD) cameras, Complementary Metal-Oxide-Semiconductor (CMOS) cameras installed in front, rear, left, and right of vehicles, etc.Acoustic sensor, shock sensor, speed sensor, ambient speed detection in case of specific speed abnormal and excessive brake use, image Photographing or recording using motion detection by; The data is digitized and recorded on A / V (Audio / Video) storage media such as HDD (Hard Disk Driver), CD (Compact Disk), flash memory, and diskette, which are digital recording devices of DVR (Digital Video Recorder). ; By visually and audibly reproducing them in the analysis of accidents and surrounding conditions; It is a car DVR (Digital Video Recorder) that includes a black box function to objectively determine the cause of accidents and situations.

The configuration and operation of the device of the present invention will be described in detail with reference to the accompanying drawings.

1 is a state diagram in which a surveillance camera and a DVR having a black box function are mounted on a vehicle. The automobile DVR 100 and the surveillance camera modules 201, 202, which serve as a black box function in a driving or stopped vehicle 200 are illustrated in FIG. The side monitoring ranges 213 and 214 and the rear monitoring range 212 and the like are shown as shown in the state where the 203 and 204 are attached and the limits of the monitoring range 211 that the front camera module 201 can monitor. It is shown. However, a concept including a microphone for sound monitoring and various sensors capable of monitoring the surroundings of a vehicle such as a sensor, an impact sensor, and a speed sensor without limiting the surveillance camera modules 201, 202, 203, and 204 to a surveillance camera. It is done.

FIG. 2 is a situation diagram of monitoring a vehicle's surroundings and interfacing the result when the vehicle is stopped. The DVR 100 including a black box function for storing various images necessary for digital video, sound, and car monitoring is provided with a surveillance camera and various sensors. After receiving the surveillance image and various sensor input data by the functional devices 201, 202, 203, and 204, and converting the data to digital, the black box function of the image and various sensor data on the object 400 being monitored is real-time. Database to the DVR including a. Monitoring data related to database image and various sensor data can be connected to general PC or specialized computer system (301) and can be searched through monitor (302). The efficiency of the can be further enhanced.

FIG. 3 is a block diagram showing each module of each system operation. The surveillance video 201, the microphone and the acoustic sensor 223, and the various sensors 222 attached to the vehicle 200 are monitored video, surveillance sound, and surveillance, respectively. The data is input to the video / audio input terminal 103 and the sensor input / output port 101 of the DVR 100 having a black box function, and are transmitted in real time from the digital video / audio memory 105 via the analog-to-digital conversion terminal 104. The multimedia processing stage 102 for processing the compression / display is reached and processed. In the event of events such as motion detection, sound detection, and various sensor monitoring data generation, backup data is stored and stored in digital storage media such as main memory 108 by using a proprietary algorithm and monitoring data for various sensor data. When using the data backup device 107 and the device 106 for compensating the vibration of the vehicle to prepare for the impact and the intensity, and also to decode the stored data, to connect to the external search device 300 (301) to search In this case, the display device 302 is used. Control the pan / tilt equipment 225 to move the surveillance camera and microphone device up, down, left and right, control the zooming equipment 224 used to enlarge and reduce the image, or flash 227 and infrared for night surveillance.
