DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an active vehicle disaster relief apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an active vehicle disaster relief device according to the present invention, FIG. 2 is a block diagram illustrating the configuration of the disaster relief device of FIG. 1, and FIG. 3 is a block diagram Fig.

As shown in the figure, the active vehicle disaster relief apparatus according to the present invention includes a case 10 mounted inside a vehicle; A camera (20) installed in the case (10) for shooting an image of the surroundings of the vehicle and generating a video signal; A microphone (30) for sensing a sound generated in the surroundings of the vehicle and generating a corresponding sound signal; A sensor module unit 40 for sensing a vehicle state and generating a corresponding sensing signal; A weight assigning unit (50) for giving a first weight (A) to a sound signal generated by a microphone (30) and giving a second weight (B) to a sensing signal generated by the sensor module unit (40); A GPS module (60) for measuring the position and speed of the vehicle and generating a corresponding position velocity signal; A memory 70 for storing the video signal, the sound signal, the position velocity signal, and the sensing signal information; An event analyzer 80 for analyzing whether the vehicle is in a normal event state in which the vehicle normally travels or in an accident event in which an accident occurred, from the sum of the first weight A and the second weight B; A disaster signal generating unit 90 for generating a disaster signal when the event analyzing unit 80 determines that the event is an accident event; An emergency rescue switch (100) operated by the driver to artificially generate the disaster signal; A wireless transmission unit 110 for wirelessly transmitting the disaster signal to a disaster center; A battery 120 for supplying power for operation; A warning signal generator 130 for outputting a warning signal when a disaster signal is generated; And a CPU 140 which is connected to the above-described configurations and is for controlling.

The camera 20, the microphone 30, the sensor module 40, the weight assigning unit 50, the GPS module 60, the memory 70, the event analyzing unit 80, the disaster signal generating unit 90, The emergency rescue switch 100, the wireless transmission unit 110, the battery 120 and the warning signal generating unit 130 are integrated into the case 10.

The case 10 is mounted on a dashboard upper side or a rear mirror inside the vehicle.

The camera 20 photographs a front side image of the vehicle and is capable of switching between the left and right side images so that the front side of the vehicle can be photographed regardless of the installation position of the case 10. [ To this end, the camera 20 is mounted on a pivotal support bracket 15 which protrudes to the upper side of the case 10 and has a ball type hinge or a hinge capable of switching in the front, back and left and right directions. Accordingly, the camera 20 can be directed to the front side of the vehicle, regardless of where the disaster relief apparatus is mounted on the dashboard.

The microphone 30 senses a sound generated in the vehicle and generates a corresponding sound signal. Through this sound signal, the volume of the sound generated inside the vehicle is rapidly changed, for example, a change in shock volume caused by a vehicle crash. The sudden change in volume can be detected according to the scream of the driver. In this way, from the sound signal generated by the microphone 30, it is recognized that the vehicle is out of the normal driving situation.

 The video signal generated by the camera 20 or the sound generated by the microphone 30 may be wirelessly transmitted to the control center by the wireless transmission unit 110 to be described later when the disaster signal is generated.

3, the sensor module 40 senses the vehicle state and generates a corresponding sensing signal. The sensor module 40 includes a G sensor 41 for sensing a change in the acceleration of the vehicle and generating a corresponding acceleration change signal, Wow; A smoke sensor (42) for sensing a smoke inside the vehicle and generating a corresponding smoke signal; A motion sensor (43) for sensing a motion of a driver inside the vehicle and generating a corresponding motion signal; And a temperature sensor (44) for sensing a temperature change inside the vehicle and generating a corresponding temperature signal.

The G sensor 41 senses a sudden acceleration change value in the three axial directions (X, Y, Z). For example, when the vehicle suddenly stops due to a sudden change in the acceleration of the vehicle, for example, a collision accident, the acceleration change in the X-axis direction is sensed to generate a corresponding X-side acceleration change signal. Or when the vehicle rotates or rolls due to a slip or crash, it senses the Y-Z axis acceleration change and generates a corresponding Y-Z axis acceleration change signal. Sensing changes in acceleration in the X, Y, and Z axis directions sensed by the G sensor 41 as described above allows the vehicle to recognize that the vehicle is out of the normal running condition.

The smoke sensor 42 senses smoke generated in the vehicle in the event of an accident and generates a corresponding smoke signal. Smoke usually occurs when a vehicle crashes, meaning that when the smoke signal is generated, the vehicle is not in a normal running condition.

The motion sensor 43 senses whether or not the driver is moving and generates a corresponding motion signal. The state of the driver can be known by the motion signal.

For example, after a change in the volume of the sound sensed by the microphone 30 or a change in acceleration sensed by the G sensor 41 occurs in a case where a larger event occurs in a normal normal driving situation, If the motion of the driver is not detected, the driver is likely to have lost his mind. That is, if the motion sensor 43 can not sense the motion of the driver while a predetermined time has elapsed after an event in which an acceleration change greater than a change in acceleration during normal driving occurs, the vehicle is not in a normal running state.

The temperature sensor 44 senses a rapid temperature change when a fire occurs inside or outside the vehicle and generates a corresponding temperature signal. When a fire occurs due to a vehicle or a fall accident, a sudden temperature change occurs inside the vehicle. Therefore, by sensing the temperature change, it can be seen that the vehicle is not in a normal running condition.

The weight assigning unit 50 assigns weights to the sound signal and the sensing signal, respectively.

Since various event situations arise in the vehicle driving, it is necessary to distinguish accurately whether it is a normal event situation caused by a driver's vehicle operation or an accident event due to an accident. The weight assigning unit 50 assigns a first weight A to a sound signal generated by the microphone 30 and a second weight B to a sensing signal generated by the sensor module 40 .

The first weight A is a value of a normal sound related to a sound generated during normal driving (noise transmitted from the outside to the vehicle, vehicle engine sound, music sound, and clash sound) in the sound signal generated by the microphone 30 This value is given to the abnormal sound volume that occurs when a vehicle collision occurs when the maximum volume is set to the reference volume value (A0). That is, since the abnormal sound volume generated when the vehicle collision occurs is larger than the reference volume value A0, the first weight A is given to indicate the possibility of an accident when the abnormal sound volume is generated. For example, when the maximum volume generated during normal driving is 70 dB, a weight value of 70 dB or more is given.

The second weight B is a value obtained by multiplying the sensing signal generated by the sensor module unit 40 by a normal sensing value generated during normal driving as a reference sensing value B0, And is a value given to an abnormal sensing signal generated in the event of an accident. That is, the abnormal sensing signal generated when a vehicle collision occurs is different from the normal sensing signal generated when the vehicle runs normally, and the weight is given when the abnormal sensing signal is generated.

Here, the second weighting value B is calculated by multiplying the acceleration weight B1 given to the acceleration signal generated by the G sensor 41, the smoke weight B2 given to the smoke signal generated by the smoke sensor 42, A motion weight B3 given to a motion signal generated by the motion sensor 43 and a temperature weight B4 given to a temperature signal generated by the temperature sensor 44. [

The acceleration weight B1 is set to a reference acceleration B10 which is a normal acceleration change value that can be generated when the driver is suddenly stopped by the driver during normal driving in the acceleration signal generated in the G sensor 41, This value is given to the abnormal acceleration change value that occurs when the vehicle collides, falls, or slips. That is, the abnormal acceleration change value occurring at the time of a vehicle collision or a crash is much higher than a normal acceleration change value generated when the driver stops at normal driving, so that when the G sensor 41 measures the abnormal acceleration change value And gives the acceleration weight value B1 to the abnormal acceleration change value. For example, the normal acceleration change value is 16m / sec2 when the driver stops at a speed of 60km for 1 second due to the will. In the case of collision or fall, the acceleration change occurs at around 0.1 second. Therefore, the abnormal acceleration change value Is at least 100 m / sec2. Therefore, when the maximum acceleration change value (normal acceleration change value) that can occur during normal driving is set to 40 m / sec2, when the acceleration change value larger than the normal acceleration change value occurs, the acceleration weight B1, .

It is also possible to give the acceleration weight (B1) even when the vehicle slips or rolls. That is, when the vehicle slips or rolls, an acceleration change occurs in the Y-Z axis, and when the G sensor 41 measures the change in the Y-Z axis acceleration, it gives an acceleration weight B1 indicating the possibility of an accident.

The smoke weight B2 is a value given to the smoke signal generated by the smoke sensor 42. [ Since smoke is not normally generated in a normal running state, a smoke weight (B2) indicating the possibility of an accident occurring when a smoke signal is sensed is given.

The motion weighting value B3 is a value obtained by subtracting the motion weight value B3 from the motion weight value of the motion sensor 43 in a state in which the first weight value A is given to the motion signal generated in the motion sensor 43 It is a value given to an abnormal motion signal generated when it does not move for more than 10 seconds.

If an accident occurs, the driver must move down from the vehicle in order to check the state of the vehicle. If the driver's motion is not detected despite the abnormal sound volume given the first weight (A) high portential. Accordingly, when an abnormal motion signal in which the driver's motion is not detected is generated for a predetermined time, for example, 10 seconds or more despite the occurrence of the first weight value A, the abnormal motion signal indicates the possibility of an accident The motion weight B3 is given.

The temperature weight B4 is a value given to the abnormal temperature signal generated by the temperature signal 44 when a sudden temperature change is sensed inside the vehicle.

In the case where a sudden temperature change occurs in a vehicle, there is a high possibility that a fire occurs due to a vehicle accident. In this case, the abnormal temperature signal is given a temperature weight (B4) indicating the possibility of an accident.

The GPS module 60 receives a signal from a GPS satellite located in the earth orbit and measures the position and velocity of the traveling vehicle to generate a corresponding position velocity signal. The GPS module 60 is exposed to the outside of the case 10 to receive GPS signals from GPS satellites accurately.

The memory 70 stores image information photographed by the camera 20, sound information sensed by the microphone 30, sensing information generated by the sensor module unit 40, Store information related to position speed. The information stored in the memory 70 provides information necessary for future accident investigation and identification of the situation at the time of an accident.

The event analyzer 80 is for determining whether the event is a normal event situation or an accident event event and may be generated in a normal event situation in which the sum of the first weight A0 and the second weight B is set Is greater than a reference sound volume value (A0) and a reference sensing value (B0), it is determined that an accident has occurred in the vehicle. For a more accurate analysis, the second weight B may be a value including the acceleration weight B1, the smoke weight B2, the motion weight B3, and the temperature weight B4.

Generally, when the vehicle travels on roads, off-roads, or mountainous areas, various driving conditions are met. That is, it is exposed to various sound environments such as various road noises, engine noises generated at high speed RPM, large music sounds, and clash sounds, and vehicle shocks applied when driving on rough roads or unpaved roads. Therefore, in a complex driving environment, it should be accurately distinguished whether it is a normal event situation in which the vehicle is operated by the driver's will, or an accident event situation in which the driver's intention is lost due to an accident.

The event analyzer 80 determines whether or not an accident has occurred in the vehicle by adding the first weight A0 and the second weight B described above.

The disaster signal generating unit 90 generates a disaster signal when the event analyzing unit 80 determines that it is an accident event situation. These disaster signals are generated automatically regardless of driver's will.

The emergency rescue switch 100 generates a disaster signal when the driver presses it by hand. The emergency rescue switch 100 is installed so as to be exposed to the surface of the case 10 so that the driver's hand can be easily accessed.

When a disaster signal is generated by the disaster signal generating unit 90 or the emergency rescue switch 100, the wireless transmission unit 110 transmits a disaster signal to the disaster center. At this time, the wireless transmission unit 110 transmits the image taken by the camera 20, the sound around the vehicle sensed by the microphone 30, and the position information measured by the GPS module 60 together. Signals transmitted from the wireless transmission unit 110 are transmitted to the disaster center through the 3G / 4G / LTE network.

The battery 120 supplies power to the components, and is built in the case 10 and is normally supplied with power from the battery of the vehicle. However, when the power supplied to the inside of the vehicle is cut off due to a vehicle accident, it operates independently to operate the active vehicle disaster relief device of the present invention.

The warning signal generating unit 130 generates a warning signal for generating a warning light and a warning sound so that people around the vehicle can recognize the occurrence of a disaster signal. For this, the warning signal generating unit 130 includes a high-brightness LED module 135, which is installed outside the case 10 to generate warning light, and a speaker 136 that generates a warning sound. In particular, the warning signal generated at night becomes an SOS signal so that an external vehicle can visually recognize the accident vehicle.

In addition, the warning signal generator 130 may be connected to the vehicle's clock or a warning lamp so as to automatically operate the alarm and the lightening when a disaster signal is generated. In this case, the external vehicle easily recognizes the accident vehicle.

As described above, according to the present invention, a first weight A is given to a sound signal generated by a microphone 30, a second weight B is given to a sensing signal generated by a sensor module 40, From the sum of the first weight A and the second weight B, it is possible to comprehensively analyze whether the normal event situation in which the driver's intention is reflected or the abnormal event situation in which the driver's intention is lost. A disaster signal, a video signal photographed by the camera 20, a sound signal around the vehicle sensed by the microphone 30, and a position information signal measured by the GPS module 60 are automatically disaster The center is able to receive all the information of the vehicle and issue an emergency rescue order.

In the case of the second weight A, the acceleration weight B1 given to the acceleration signal generated by the G sensor 41, the smoke weight B2 given to the smoke signal generated by the smoke sensor 42, The moving weight B3 given to the motion signal generated by the motion sensor 43 and the temperature weight B4 given to the temperature signal generated by the temperature sensor 44 can do.

Also, since the power is supplied by the battery 120 built in the case 10, a disaster signal can be transmitted even if all the internal power of the vehicle is shut off due to an accident event.

In addition, the warning signal generating unit 130 generates a warning sound and a warning sound in the event of an accident so that the external vehicle can recognize the accident vehicle, thereby preventing the second collision.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
