Abstract
The invention discloses a kind of systems detected applied to water clarity in municipal works are as follows: Sai Shi disk is put into anhydrous measuring cell, keeps the galvanized wire and measuring cell plane perpendicular of Sai Shi disk center；It is M1 by the contrast that imaging sensor measures Sai Shi disk picture under anhydrous condition；Waste water is pumped into measuring cell by pumping system, distance of the depth of waste water higher than Sai Shi panel surface to measuring cell bottom in measuring cell；The contrast that Sai Shi disk picture in the case of having water is measured by imaging sensor is M2；Optical transfer function MTF measures the transparency of water, wherein MTF=M2/M1.The present invention combines the detection for carrying out water clarity by CCD visual detection equipment with Sai Shi disk, contrast that is anhydrous and having Sai Shi disk picture in the case of water is measured by CCD visual detection equipment, then the transparency of water outlet can be accurately calculated by optical transfer function, this method measurement accuracy is high, finding speed is fast.
Description
Technical field
The invention belongs to municipal works fields, are related to a kind of applied to the system of water clarity detection and side in municipal works
Method.
Background technique
The case where measuring water quality in river water is needed in municipal engineering construction, currently, China develops in smelly water monitoring field
It is slow that more external colleague develops starting evening, development speed, traditional Sai Shi disk detection method be Sai Shi disk is flat into the water, gradually under
It is heavy, when to the white that just can't see disk, registered depth, the as transparency of water, due to the subjective error and light of human eye
Error, lead to that monitoring velocity is slow, the low related needs for being unable to satisfy the smelly water monitoring field being increasingly urgent to of accuracy.
Summary of the invention
The purpose of the present invention is to provide a kind of system and method detected applied to water clarity in municipal works, this is
It unites and combines the detection of progress water clarity with Sai Shi disk by CCD visual detection equipment, surveyed by CCD visual detection equipment
Contrast that is fixed anhydrous and having Sai Shi disk picture in the case of water, then can accurately calculate the saturating of water outlet by optical transfer function
Lightness, this method measurement accuracy is high, finding speed is fast, solves the problems, such as that the detection slow accuracy of speed is low in the prior art.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of system detected applied to water clarity in municipal works, including measuring cell are installed in measuring cell and are placed with
Sai Shi disk, measuring cell top are equipped with lighting device and imaging sensor, are equipped with pumping system in measuring cell.
A method of it is detected applied to water clarity in municipal works, the specific steps are as follows:
(1) Sai Shi disk is put into anhydrous measuring cell, keeps the galvanized wire and measuring cell plane perpendicular of Sai Shi disk center；
It (2) is M1 by the contrast of Sai Shi disk picture under anhydrous condition in imaging sensor determination step 1；
(3) waste water is pumped into measuring cell by pumping system, the depth of waste water is higher than Sai Shi panel surface and arrives in measuring cell
The distance at measuring cell bottom；
(4) contrast for passing through Sai Shi disk picture in the case of having water in imaging sensor determination step 3 is M2；
(5) transparency of water is measured by optical transfer function MTF, wherein MTF=M2/M1.
Preferably, described image sensor is CCD visual detection equipment.
Preferably, the camera of the CCD visual detection equipment is vertically arranged in the surface of Sai Shi disk picture.
Beneficial effects of the present invention:
The present invention combines the transparency of detection water by CCD visual detection equipment and Sai Shi disk, is set by CCD vision-based detection
Standby imaging sensor identifies the contrast of the Sai Shi disk of water filling front and back, obtains the contrast value of water filling front and back, then
The transparency that water outlet can be accurately calculated by optical transfer function not only increases inspection instead of traditional eye-observation
The accuracy of survey improves detection efficiency simultaneously.
