INLINE SIGNAL REPEATER FOR A TRANSMISSION LINE BASED ELECTRIC FENCE FOR IMPROVING AN OPERATION DISTANCE

摘要

PURPOSE: An inline signal repeater for a transmission line based electric fence can be supplied electric power with a pair of wires.;CONSTITUTION: A forward amplifier(32) includes a differential inputting unit and a differential outputting unit and amplifies a forward signal. A backward amplifier(33) includes the differential inputting unit and the differential outputting unit, and amplifies the forward signal. A mono stable circuit(41) is triggered with an output of the forward amplifier. The mono stable circuit outputs an electric pulse with preset pulse width. A four poles double throw signal switch(42) connects a pair of wires of a transmission line to the forward amplifier in a steady state. The four poles double throw signal switch connects to the backward amplifier, when the four poles double throw signal switch is triggered with an electric pulse output of the forward amplifier.;COPYRIGHT KIPO 2013;[Reference numerals] (12,13) Low pass filter; (31) Voltage regulator; (41) Mono stable circuit
