ABNORMAL SIGNAL DETECTING SENSOR WITHOUT POWER SUPPLY CAPABLE OF UTILIZING BIAS SIGNAL OF OUTPUT LINE AND ENERGY OF DETECTED SIGNAL AS POWER OF THE WHOLE SENSOR

摘要

PURPOSE: An abnormal signal detecting sensor without power supply is provided to manage a thunderbolt or a surge current in the remote by driving a switch of an output end after converting a short time signal to a long time signal.;CONSTITUTION: An abnormal signal detecting sensor without power supply comprises the following: a noncontact detector(10) detecting surge input from a detected line; an input forming unit(20) rectifying the output of the noncontact detector; a micro capacitor(30) storing a DC component outputted form the input forming unit; an amplifier(40) amplifying a saved surge signal stored in the micro capacitor; and a delay signal(50) converting the output signal to a switching signal.;COPYRIGHT KIPO 2010
