The communication unit 102 performs communication with an external device. The external device may include a server installed in an institution such as a police station, a fire station, etc., a user terminal device (e.g., a smart phone), and the like.

The communication unit 102 is a communication unit that interconnects the helmet 100 and an external device through a communication network. The communication unit 102 may be a wireless communication module such as mobile communication or satellite communication, a wired communication module such as the Internet, Modules, and the like.

In addition, the communication unit 140 may transmit information on an external image to an external device, and may transmit or receive an audio signal of an external device or a voice call when the external device is a mobile terminal. And may further include a speaker 122 and a microphone 120 for voice communication of an audio signal. The speaker 122 may be installed near the user's ear when the helmet 100 is worn. Preferably, at least two speakers 122 are provided for listening to music and may have a stereo function. The microphone 120 may be installed near the mouth when the user wears the helmet 100. The microphone 120 and the speaker 122 will be embedded in the helmet 100.

The display unit 104 displays the backward image under the control of the controller 114.

The photographing unit 106 photographs the back of the helmet 100 and transmits the photographed image to the control unit 114. [

When an impact is detected, the impact sensor 108 detects the impact value and transmits the impact value to the control unit 114.

As the impact sensor 108, one of a geomagnetic sensor, an acceleration sensor, or a gyro sensor may be used. The controller 114 monitors a value measured at a certain period in the geomagnetic sensor, the acceleration sensor, or the gyro sensor, and determines that the impact is applied when the value is changed over a predetermined value. As the impact sensor 108, any sensor capable of detecting an impact other than the above sensors can be used.

The beacon unit 110 emits an ultrasonic signal, and transmits a signal to the control unit 114, which is returned to the rear vehicle. The beacon unit 110 may include, for example, an ultrasonic sensor or the like.

The warning generating unit 112 generates a warning with light or sound under the control of the control unit 114. [ The warning generating unit 112 may include a light emitting unit that generates light, a speaker that transmits sound, and the like.

The position measuring unit 116 measures the current position. The position measurement unit 116 may be, for example, a GPS module.

The control unit 114 activates the photographing unit 106 to photograph the image when traveling starts and stores the image data provided from the photographing unit 106 in the storage unit 124. [

The control unit 114 processes the image photographed by the photographing unit 106 and controls the display unit 104 to output the processed image. That is, the control unit 114 converts the image photographed by the photographing unit 106 into a video signal that can be outputted from the display unit 104, and outputs the converted video signal to the display unit 104. [

The control unit 114 determines whether or not an accident has occurred by using the image captured by the photographing unit 106 or the impact value detected by the impact sensor 108 and transmits the field information to the communication unit 102 through the communication unit 102 To the predefined external device. The field information may include the image, time, location, etc. of the site.

In other words, the control unit 114 analyzes the image photographed by the photographing unit 106. When the rear vehicle is not in the forward direction by a predetermined angle or more, when the backward vehicle and the vehicle aboard the user coexist, And transmits the image to the external device as the scene information. If the impact value detected by the impact sensor 108 is equal to or larger than the predetermined value, the control unit 114 determines that an accident has occurred, and transmits the image at that time to the external device as the scene information. The control unit 114 determines whether an accident has occurred by combining the image photographed by the photographing unit 106 and the impact value detected by the impact sensor 108. If it is determined that an accident has occurred, And transmits the information to an external device.

When the communication unit 102 is capable of only local communication, the control unit 114 transmits the site information to the user terminal device, and the user terminal device can transmit the site information to the server of the predefined institution.

Upon receiving the ultrasonic signal from the beacon unit 110, the control unit 114 calculates the distance to the rear vehicle based on the received ultrasonic signal, and generates a warning according to the calculated distance. That is, the control unit 114 calculates the distance based on the time difference from the echo signal, which is emitted when the ultrasonic signal is emitted from the beacon unit 110, and the ultrasonic signal is reflected back from the obstacle. Then, the control unit 114 determines whether the calculated distance is smaller than a preset threshold distance. If the calculated distance is smaller than the predetermined threshold distance, the control unit 114 generates an alarm through the alarm generating unit 112. That is, if the distance from the motorcycle to the rear vehicle is smaller than the predetermined threshold distance, the probability of a collision increases, and it is therefore necessary to notify the driver of the motorcycle.

The control unit 114 may emit light through the light emitting unit of the warning generating unit 112 to provide a warning to the driver driving the rear vehicle. At this time, the control unit 114 may emit the light emitting unit in a different manner depending on the distance from the rear vehicle. In addition, the control unit 114 may provide a sound to the driver of the motorcycle or the driver of the rear car through the speaker of the warning generating unit 112. [ In this case, the warning provided to the driver of the motorcycle may be a caution message because it is close to the rear vehicle. Or the driver of the rear car may be a warning sound such as an alarm sound.

Accordingly, the driver of the motorcycle or the driver of the rear car has a vigilance against a collision accident, and the risk of collision can be reduced. Here, the beacon unit 110 is provided behind the helmet to reduce the risk of collision with the rear vehicle, but the beacon unit 110 may be installed on the right and left sides of the helmet. In this case, the motorcycle driver can be provided with a warning of a collision accident with respect to the cars on the right and left sides of the motorcycle.

The control unit 114 may include at least one computing unit, which may be a general purpose central processing unit (CPU), a programmable device device (CPLD, FPGA) that is suitably implemented for a specific purpose, (ASIC) or a microcontroller chip.

The switch unit 118 supplies power to the driving unit (not shown) of the photographing unit 106 and the display unit 104 and controls the power supply button and the power- When the power supply button is selected in conjunction with the control unit 114, the control unit 114 supplies power to the battery 126 and cuts off the power supply when the power off button is selected.

If the switch unit 118 is not provided, the control unit 114 can perform power supply or power off through voice command recognition using the microphone 120.

The control unit 114 converts the image photographed by the photographing unit 106 into a digital signal, compresses and restores the digital image into MPEG (Moving Picture Experts Group), and transmits the digital signal to the storage unit 124, .

The storage unit 124 is preferably a memory card in which compressed image data is stored in the controller 114 and the digital signal once recorded is not erased. It is similar in size to a CF memory card (Compact Flash Memory Card) and a CF memory card, but has a remarkably small MMC (Multi Media Card). It is highly compatible, has a relatively small size, An SD memory card (Secure Digital Memory Card) or the like is used.

The storage unit 124 may be formed with a connection socket (not shown) on the outer cover so that the image data stored in the storage unit 124 can be connected to an external computer or the like so that the user can check the stored image data from the outside.

The battery 126 may be a built-in rechargeable battery or a removable battery pack.

In the helmet 100 constructed as above, when the helmet wearer selects a power supply button of the switch unit 118 or inputs a power supply voice command, the controller 114 senses the power supply button, The display unit 104 is operated by supplying power to the display unit 104 and the image photographed by the photographing unit 106 is transmitted to the display unit 104 so that the wearer can check the image of the rear side.

When the wearer wearing the helmet 100 selects a power cutoff button of the switch unit 118 or inputs a power off voice command, the controller 114 cuts off the power supplied to the drive unit of the display unit 104 So that the display unit 104 is placed in a normal state and the image photographed by the photographing unit 106 is stored in the storage unit 124.

In this manner, a photographing unit 106 is provided behind the helmet 100, and a display unit 104, which outputs an image photographed by the photographing unit 106, is provided in front of the helmet 100, It is possible to check the image of the rear side through the unit 104 in real time, thereby improving the ability to cope with safety accidents and minimize human accidents.
