Intelligent monitoring system for manhole drainage

Abstract

This invention relates to a smart monitoring system for manhole drainage, comprising at least: a water level sensing unit, at least one motor detection unit, at least one current detection unit, a monitoring and judgment unit, a communication unit, and a remote monitoring platform. The water level sensing unit is installed in a manhole to detect the water level. The motor detection unit is installed on the pumping motor of the manhole to detect whether its operation is normal. The current detection unit is installed on the pumping motor to detect its current. The monitoring and judgment unit receives the detection results and judges the drainage status of the manhole. The communication unit sends the judgment of the monitoring and judgment unit to the remote monitoring platform. Users can remotely connect to the remote monitoring platform through their electronic devices to read and view the drainage status of the manhole, thereby achieving the purpose of real-time monitoring.
