Abstract:
A monitoring system includes one or more monitoring devices, positioned in sewer manholes, storm drains, etc. , and a remote monitoring station that communicates wirelessly therewith. The monitoring device may be an integrated unit, including sensors, a two-way telemetry unit, a power supply, a processor, and supporting hardware, all located in an enclosed, waterproof housing. The monitoring device is placed within a manhole cavity to obtain depth (e. g. , water level) measurements, images, and other data, and report the measurements back to the remote monitoring station, which analyzes the data and responds to alert messages when a dangerous water level is detected. An additional sensor may monitor the manhole cover for security purposes. A distributed mesh network of wireless nodes may be used to relay communications from the monitoring devices along alternative paths, through bridge nodes that may connect to a public wireless or cellular network.
