Abstract
A monitor for monitoring the conditions of and around and under a manhole cover senses current conditions of the manhole cover and enables wireless self-reporting of such conditions at intervals and upon certain emergency situations arising. The monitor of the manhole cover includes a shell, a cover plate, and a base. The cover plate is detachably assembled with the shell. The base connects the shell with the manhole cover. The base includes a magnet to which the manhole cover is strongly attracted. The monitor is held to the manhole cover by the magnet. A mounting operation of the monitor requires only placement by hand.
Claims18
A manhole cover monitor for monitoring conditions of a manhole cover, the manhole cover monitor comprising:
- a shell configured to connect with the manhole cover;
- a cover plate detachably assembled with the shell;
- and
- a base configured to connect with the shell to the manhole cover;
- the base comprising a magnet configured to apply a magnetic attraction force to the shell;
- wherein the base and the shell are disposed between two opposite sides of the cover plate;
- two opposite surfaces of the magnet are respectively connected with the cover plate and the manhole cover thereby mounting the cover plate on the manhole cover.
A manhole cover monitor for monitoring conditions of a manhole cover, the manhole cover monitor comprising:
- a shell configured to connect with the manhole cover;
- a cover plate detachably assembled with the shell;
- a base configured to connect with the shell to the manhole cover;
- the base comprising a magnet configured to apply a magnetic attraction force to the shell;
- a detection module, configured to sense conditions of the manhole cover;
- and
- a control module, configured to process data related to the conditions sensed by the detection module;
- wherein the detection module comprises at least one sensor unit;
- the at least one sensor unit comprises a posture sensor;
- the posture sensor senses an acceleration change;
- the control module presets a predefined acceleration value;
- when the acceleration sensed by the posture sensor exceeds the predefined acceleration value, the control module counts a times of the acceleration being exceeded the predefined acceleration value;
- when the accumulated times reaches a predefined time value, the control module determines that the manhole cover is in a loose state.
