Real-time monitoring and controlling systems for water quality safety of surface runoff of highway bridge and grand bridge

Abstract

The invention provides real-time monitoring and controlling systems for the water quality safety of surface runoff of a highway bridge and a grand bridge. The real-time monitoring and controlling system for the water quality safety of surface runoff of the grand bridge comprises a water quality safety detection unit and a computer-aided analysis and control system, wherein the water quality safety detection unit is a microwave detection apparatus; the output signal of the microwave detection apparatus is connected with the computer-aided analysis and control system; the microwave detection apparatus is mounted on a bridge surface runoff main pipe; the draining end of the bridge surface runoff main pipe is provided with an electrically-operated valve; and the electrically-operated valve is controlled by and connected with the computer-aided analysis and control system. The real-time monitoring and controlling system for the water quality safety of surface runoff of the common road bridge comprises the water quality safety detection unit, the computer-aided analysis and control system and a draining valve, wherein the microwave detection apparatus is mounted on the draining end of a pipeline on the bridge or a bridge surface runoff collecting pool; the output signal of the microwave detection apparatus is connected with the computer-aided analysis and control system; the computer-aided analysis and control system controls the draining valve; and the draining valve is mounted on a drainpipe of the bridge surface runoff collecting pool.

Description

technical field [0001] The invention relates to a safety monitoring system for runoff water quality of road bridge deck, in particular to a real-time monitoring control system for water quality safety of runoff water quality of road bridge deck using microwaves for water quality safety detection. Background technique [0002] At present, with more and more vehicles carrying dangerous chemicals in road traffic, the types of dangerous goods transported are also becoming more and more complex. During the construction of highway transportation infrastructure, some highways are inevitably built across rivers and rivers, and some highways cross water bodies with relatively high water quality requirements. Once a dangerous chemical leakage accident occurs during transportation, it is located in a remote place and it is inconvenient to rescue. It is very easy to cause pollution to the water body under the bridge, nearby water sources, aquatic resource protection areas, wetland prote...

Problems solved by technology

Some water collection systems are equipped with online water quality monitoring systems, but they mainly monitor water quality CODcr, PH value and suspended solids, which belong to routine water quality "pollution" monitoring, not water quality "safety" monitoring, and do not meet the national requirements for bridge deck runoff safety. monitoring requirements

These water quality online monitoring devices are not only expensive, but also complex in structure, and it takes a long time for the test results to meet the needs of "instant judgment" for super-large bridge deck runoff safety monitoring.

Some use more sensors, and the processing process is cumbersome; some have a single structure, but limited functions, and the use environment is also limited by actual conditions.
