Title:
SYSTEM FOR MONITORING CORROSION PREVENTION STATE OF STEEL STRUCTURE
Document Type and Number:
Japanese Patent JP2019215289
Kind Code:
A
Abstract:
To provide a system for monitoring a corrosion prevention state of a steel structure capable of diagnosing a corrosion prevention state of a steel structure without going to an actual place.SOLUTION: The system for monitoring a corrosion prevention state of a steel structure comprises a metal piece 11 fixed to a steel structure 10, a current measurement unit 18 for measuring current which flows by corrosion of the metal piece 11, a data collection unit 19 for collecting chronological data of the current to transmit the data to a server 21 of the Internet 20, and a monitoring terminal 23 for monitoring a corrosion prevention state of the steel structure 10 through communication with the server 21. The server 21 includes a storage unit for storing the chronological data, a computation unit for computing corrosion speed of the steel structure 10 and a determination unit for determining a corrosion state of the steel structure 10. The monitoring terminal 23 displays the corrosion speed of the steel structure 10 obtained by the computation unit and a determined result obtained by the determination unit.SELECTED DRAWING: Figure 4
