<p>The present invention relates to an alarm signal apparatus for emergency situation on a road. The alarm signal apparatus includes: a stand pillar (11) which is installed upright along a road (H); a first solar cell (14a); a first storage battery (14c) charged with a current inputted from the first solar cell (14a); a first button switch (16a) to inform emergency situation occurrence; a control board (15) which controls light emission of a light emitting part (13) by outputting an operation control signal to the light emitting part (13) in case a first input signal is inputted from the first button switch (16a), and outputs a transmission control signal to a first communication module (17) in order to transmit an emergency situation occurrence notice signal to another rear signal flag (10) installed on the road (H) in case the first input signal is received from the first button switch (16a); the light emitting part (13) emitting a light on the basis of the control of the control board (15); and the first communication module (17) which transmits the emergency situation occurrence notice signal to another rear signal flag (10) registered on the basis of the transmission control signal received from the control board (15). The rear signal flags (10) receiving the emergency situation occurrence notice signal from the corresponding signal flag (10), where the first button switch (16a) operates, makes the light emitting part (13) flicker by the control of the control board (15). By this, a vehicle traveling behind can receive alarm of vehicle accident occurrence by a simple configuration.</p> |
