COMMUNICATION SYSTEM IN SEWER LINE, MONITORING SYSTEM IN SEWER LINE, AND COMMUNICATION DEVICE IN SEWER LINE
PROBLEM TO BE SOLVED: To provide a communication system that can easily install communication means by an inexpensive and simple structure in a wide range of sewer pipe networks, and can construct the communication system with an excellent communication state.SOLUTION: The monitoring system in the sewer line is configured to include a communication sonic transmitter 12a disposed in a manhole 2 disposed at a distance from each other in the sewer line 3 and to transmit an ultrasonic wave P from one manhole 2, a communication sonic receiver 12b for receiving the ultrasonic wave p transmitted from the communication sonic transmitter 12a by the other manhole 2, and a water level information detector 13 for detecting the water level information D of sewage circulating within the sewer line 3 based on a communication state received by the communication sonic receiver 12b.SELECTED DRAWING: Figure 4
【課題】広範囲の下水管網において安価で簡単な構造により通信手段の取り付け作業を容易に行うことができ、かつ優れた通信状態の通信システムを構築することができる。【解決手段】下水管路３で互いに距離をあけて配置されるマンホール２内に配置され、一方のマンホール２から超音波Ｐを発信する通信用音波発信器１２Ａと、通信用音波発信器１２Ａから発信された超音波Ｐを他方のマンホール２で受信する通信用音波受信器１２Ｂと、通信用音波受信器１２Ｂで受信した受信状態に基づいて下水管路３内を流通する下水の水位情報Ｄを検出する水位情報検出部１３と、を備えた構成の下水管路内監視システムを提供する。【選択図】図４
