SEDIMENT MOVEMENT OBSERVATION SYSTEM
PROBLEM TO BE SOLVED: To prevent a sediment movement observation system that hardly causes false detection and false alarm.SOLUTION: A sediment movement observation system 1 observes inflow or access of sediment to an object to be conserved and comprises a movable body 4, which is set to the sediment to be observed 3, and a sending device 5, which is built in the movable body and can send a low frequency magnetic field signal, and receiving devices (6, 7, 8), which detect the low frequency magnetic field signal sent from the sending device. The receiving devices includes: a receiving device 6 for maintenance installed near the sediment to be observed; and the receiving devices (7, 8) for movement installed near the object to be conserved function. A detection range 61 of the receiving device for maintenance is separated from detection ranges 71, 81 of the receiving devices for movement.SELECTED DRAWING: Figure 1
【課題】誤検知や誤報知の起き難い構成の土砂移動観測システムを提供する。【解決手段】保全対象物への土砂の流入又は接近を観測するための土砂移動観測システム１である。そして、観測対象３となる土砂に対して設置された移動体４と、移動体に内蔵された低周波電磁界信号の発信が可能な発信装置５と、発信装置から発信された低周波電磁界信号を検知する受信装置（６，７，８）とを備えている。また、受信装置としては、観測対象となる土砂の近辺に設置されたメンテナンス用受信装置６と、保全対象物の近辺に設置された移動時用受信装置（７，８）とが存在しており、メンテナンス用受信装置の検知範囲６１と移動時用受信装置の検知範囲７１，８１とは離隔している。【選択図】図１
