Pipeline abnormality monitoring method and pipeline abnormality monitoring system

摘要

PROBLEM TO BE SOLVED: To provide an effective continuous abnormality monitoring method for an enormous and vast pipeline network. An IC tag 7 is held by a holding member 5 in a manhole structure 3 on the upstream side. When the water level of the sewage stream 9 in the manhole structure 3 rises to the holding height of the IC tag 7 or exceeds the holding height of the IC tag 7, the IC tag 7 floats on the sewage stream 9 and separates from the holding member 5 and lowers. It moves to the downstream side along with the flow of water flow 9. When the IC tag 7 passes through the manhole structure 13 on the downstream side, the IC reader device 15 provided in the manhole structure 13 acquires the identification information of the IC tag 7. When the IC reader device 15 acquires the identification information of the IC tag 7, it transmits the acquired identification number and / or the corresponding manhole structure information to the administrator's mobile terminal 17.
