PROBLEM TO BE SOLVED: To efficiently evaluate corrosion risk of a pipe line while suppressing consumption of n when monitoring an operation condition of a selective flow exhaust vessel.SOLUTION: A remote monitoring system of anticorrosion facility includes: a selective flow exhaust vessel 1 connected between a rail R of a DC electric railway D1 and a pipe line P embedded under the rail R; a remote monitoring means 2 that is driven by a battery 20 and that remote-sends monitoring information relating to an operation condition of the selective flow exhaust vessel 1; and an amount of rainfall sensor 3 that detects an amount of rainfall in vicinity of an installation place of the selective flow exhaust vessel, and outputs it to the remote monitoring means 2. The remote monitoring means 2 includes: a measuring means 21 that measures an operation condition of the selective flow exhaust vessel 1; and an arithmetic processing means 22 that extracts measured data measured by the measuring means 21 based on time to be timed, performs arithmetic processing of extracted measured data, and outputs monitoring information; and an information transmission means 23 that remote-sends monitoring information. A set time period in which operation frequency of a DC electric railway is high and a set time period after the amount of rainfall sensor 3 detects an amount of rainfall that exceeds a set threshold monitoring are made monitoring time, the remote monitoring means 2 is driven only for monitoring time, monitoring information is output. |
