Title:
DEVICE AND METHOD FOR DRIVING ROAD STUDS
Document Type and Number:
WIPO Patent Application WO/2013/176354
Kind Code:
A1
Abstract:
One embodiment of the present invention relates to a device for driving road studs. The device for driving road studs includes: a motion sensing unit; a control unit connected to the motion sensing unit and the preceding road stud driving device; and a lamp unit connected to the control unit. In said case, the control unit changes the state of a lamp driving signal to turn the lamp unit on if a moving object is sensed by the motion sensing signal of the motion sensing unit, determines whether a driving identification signal is applied, and outputs a driving identification signal, which has a stage defined according to the moving speed of an object, to the next road stud driving device, if it is determined that the driving identification signal is applied. Moreover, when a moving object is not sensed by the motion sensing signal, the control unit determines whether a driving identification signal is applied from the preceding road stud driving device, changes the state of the lamp driving signal to turn the lamp unit on if it is determined that the driving identification signal is applied from the preceding road stud driving device, determines the state of the driving identification signal from the preceding road stud driving device, outputs the driving identification signal, which is in a state defined in accordance with the state of the determined driving identification signal, to the next road stud driving device, and turns the lamp unit off if it is determined that the driving identification signal is not applied.
