PURPOSE: A no power train approach alarm system and a control method thereof are provided to change the change of pressure due to the load of a train into electric energy by installing a piezo-electricity device on the line. CONSTITUTION: At least one power generator(1) is formed between a railroad tie and a rail with a constant interval. The power generator generates a current with the strong pressure due to the load of a train passing a rail. An alert part(6) is connected to the power generator. The alert part generates a visual/auditory signal with electrical energy. The alert part is installed in one side or two side of a rail. The power generator comprises a bracket which is installed between railroad ties, a piezo-electricity device which is fixed to the upper part of the bracket, and a charger which is fixed to the lower part of the bracket. |
