The light emitting module 110 is capable of displaying predetermined characters or phrases such as "attention", "accident occurrence", "safe operation", etc. by blinking or lighting the LEDs according to the control of the controller 300.

The emergency light emitting unit 100 is installed on the deliner 50 so that the emergency light emitting unit 100 can be moved up and down by the elevator driving unit 150 installed between the deliner 50 and the deliner 50, As shown in Fig.

The lifting and lowering driving unit 150 includes a fixed rail 151 provided at one side of the deliner 50 and provided with a moving support groove 152 extending in the vertical direction at the center, A movable rail 161 provided with a movable support protrusion 162 extending in the up and down direction so as to be movable along the movable support groove 152 in a state in which the fixed rail 151 is fixed to the movable support groove 152 of the fixed rail 151, A screw member 171 screwed to the movable rail 161 and a drive motor 173 rotating the screw member 171 under the control of the controller 300 in normal and reverse directions.

The emergency light emitting unit 100 is normally hidden behind the deliner 50 through the elevation driving unit 150. When it is determined that an accident has occurred by the controller 300 and an emergency control signal is received from the controller 300 Power is supplied to the light emitting module 110 by the emergency control unit 120 and the light emitting module 110 is operated while the driving motor 173 is operated by the emergency control unit 120, And exposed to the upper portion of the magnet 50.

The impact sensor 210 senses a physical force such as a vehicle touching or hitting a road facility directly, and transmits the sensed physical force to the controller 300.

The distance sensor 220 senses the distance between the road facility and the vehicle and whether the vehicle is parked or not. The distance sensor 220 measures the distance from the installed position to the vehicle located in the direction orthogonal to the road facility, do.

The microphone 230 is used to acquire sound generated in the event of a vehicle accident, and acquires sound or noise around the installed position and sends it to the controller 300.

The controller 300 receives the sensing information sensed by the sensor unit 200 and determines whether or not an accident has occurred in the vehicle according to the sensed information. And controls the operation of the plurality of emergency light emitting units (100).

The controller 300 determines whether the impact value sensed by the impact sensor 210 is equal to or greater than a predetermined reference impact value or a distance value sensed by the distance sensor 220 is less than or equal to a set reference distance value, It is determined that an accident caused by the vehicle has occurred and an emergency control signal for operating the emergency light emitting unit 100 is transmitted through the main communication unit 430. [

For example, when the impact information detected by the impact sensor 210 exceeds the set reference impact value, the controller 300 determines that an accident has occurred, and transmits an emergency control signal for operating the emergency light emitting unit 100 Output.

Alternatively, when the distance information detected by the distance sensor 220 is within a set reference distance or the sensed distance information continues for a set time within a reference distance, the controller 300 determines that an accident has occurred, And outputs an emergency control signal for operating the light emitting portion 100.

In another example, the controller 300 outputs an emergency control signal for activating the emergency light emitting unit 100 when the decibel of the sound obtained by the microphone 230 is equal to or higher than a set reference decibel.

To this end, the controller 300 is further provided with a frequency analyzing unit for analyzing a frequency component of sound and a memory for storing information on frequency components of sound occurring in a real vehicle accident.

In addition, the controller 300 receives the detected speed information from the speed sensor for a predetermined time, analyzes the received speed information, and determines an accident when the speed of the vehicle falls below a predetermined rate within a set time. That is, only a certain range of deceleration conditions that change per unit time is selectively detected to determine whether or not an accident has occurred.

The communication unit 400 enables communication between the emergency light emitting unit 100 and the controller 300, the controller 300 and the sensor unit 200, the emergency light emitting unit 100 and the sensor unit 200, An emergency communication unit 410 installed in the light emitting unit 100, a sensor communication unit 420 installed in the sensor unit 200, and a main communication unit 430 installed in the controller 300.
