PROTECTION POTENTIAL MEASUREMENT SYSTEM OF UNDERGROUND PIPELINE OF HIGH-SPEED MOBILE BASED ON LOW-POWER

摘要

The present invention provides a protective potential measurement system of a high speed movable underground buried pipeline based on low power which measures a potential of a reference electrode used in protective potential measurement of the underground buried pipeline and a sacrificial anode for connecting a cathode to a buried pipeline to prevent corrosion of the buried pipeline by attaching a potential measurement data logger to a lower part of a manhole cover in order to measure a protective potential of the underground buried pipeline, and stores the measured protective potential data in a memory part. A worker installs a movable gateway in a vehicle to measure the protective potential of the underground buried pipeline and passes by a position where the potential measurement data logger is installed by driving the vehicle. And when the movable gateway requests data transmission to the potential measurement data logger, the potential measurement data logger transmits the protective potential data measured in advance and stored in the memory part to a movable data logger through wireless communication. And the system can measure and evaluate the protective potential of the underground buried pipeline simply as the worker drives the vehicle, by comparing the transmitted data with a reference protective potential value established in a data analysis part in advance.
