The invention relates to a tube
cathode protection inspection and
monitoring system, comprising a
cathode protection
data monitoring center, at least one first
wireless intelligent telemetering terminal, and a plurality of second
wireless intelligent telemetering terminals, wherein the
cathode protection
data monitoring center is used for receiving, analyzing and storing data sent by
wireless intelligent telemetering terminals installed in a
pipe network and providing an underground
pipe network cathode
protection system security monitoring service for a
client; the at least one first wireless intelligent telemetering terminal is installed on the
pipe network, is connected with a constant potential
rectifier and is used for detecting U+
voltage signals, I+ current signals, RE
electric potential signals and SR given potential
signal parameters of the cathode
protection system of the constant potential
rectifier, and the plurality of second wireless intelligent telemetering terminals are installed on the pipe network, are connected with test posts and are used for detecting the cathode potential and power-failure potential parameters of the test posts. The tube cathode protection inspection and
monitoring system provided by the invention is mainly used for solving the technical problems that the manual poling labor intensity is large, the cost is high, and the poling precision is low; according to the tube cathode protection inspection and
monitoring system, the stray current influence and
electromagnetic interference on an underground pipe network can be eliminated, and the U+, I+, RE and SR parameters of the cathode
protection system can be immediately, correctly and completely monitored.
