US 2011/0255735 A1 · PROBE MONITORING SYSTEM FOR RIVERBED ELEVATION MONITORING AT BRIDGE PIERS

Abstract

A probe monitoring system for riverbed elevation monitoring at bridge piers is revealed. The system includes a housing, a measuring rod, a moving member, a control module, a photographic unit and a sensing unit. The housing is fixed on the pier. Both the moving member for driving the measuring rod and the control module for control of the moving member are mounted in the housing. When the control module drives the measuring rod to move downward and the sensing unit on the bottom of the measuring rod approaches the riverbed, a sensing signal is sent to the control module. Thus the moving member stops moving the measuring rod and the photographic unit takes pictures of the measuring rod to generate an image. Then the riverbed elevation is obtained according to the image or the movement of the moving member and is sent to a remote monitor unit for real-time monitoring.

Dependent claims

A probe monitoring system for riverbed elevation monitoring at bridge piers comprising:

a housing fixed on a bridge pier,
a measuring rod disposed on the housing and having a plurality of scales,
a moving member mounted in the housing and driving the measuring rod to move,
a control module arranged in the housing and coupled to the moving member for control of the moving member that drives the measuring rod,
a photographic unit that is set in the housing, taking pictures of the measuring rod and generating at least one image, and
a sensing unit disposed on a bottom of the measuring rod;
wherein the control module controls movement of the measuring rod;
once the sensing unit approaches a riverbed under the water, the sensing unit sends a sensing signal to the control module so as to control the moving member, stopping the moving member from moving the measuring rod and also to control the photographic unit take pictures of the measuring rod and generating at least one image;
elevation of the riverbed is obtained according to the image and the elevation of the riverbed is sent to a remote monitor unit.
