Abstract
The utility model relates to a gray-level-identification-based water quality detecting device. The device comprises a water quality camera, a video analog/digital (A/D) module, a central processing unit, a video digital/analog (D/A) module, a monitor and a digital pipe circuit, wherein the water quality camera is used for acquiring an image for identifying water quality gray level; the video A/D module is connected with the water quality camera; the central processing unit is connected with the digital signal output end of the video A/D module; the video D/A module is connected with the central processing unit; the monitor is connected with the analog signal output end of the video D/A module; and the digital pipe circuit is connected with the central processing unit and is used for displaying the water quality on site in real time. The low gray level (brightness value) of the sampled image of a water body indicates the poor water quality, and vice versa. Therefore, when the water quality is detected, a corresponding water quality conclusion can be drawn by calculating the total gray level of the water body. The utility model adopts the detection principle that: the water body image shot by the camera is compared with a standard sample which is stored primarily, and then the water quality is precisely detected.
Description
Technical field
The utility model relates to the technical field of level measuring, specifically is a kind of water quality detecting device based on gray scale identification.
Background technology
Water quality parameter has been described the quality of water body; Because a large amount of waste liquids that the industrialization manufacturing produces and the use of agriculture chemistry medicament; Cause the water more serious contamination; Adopt in time, effectively, water quality monitoring system accurately, the countermeasure of can dealing with fast, for reduce discharging, pollution treatment has great significance.
Thereby need a cover to collect convenience, the practical solution of on-site data gathering, real-time Transmission and Long-distance Control.
The utility model content
The technical matters that the utility model will solve provide a kind of simple in structure, cost is lower, be suitable for accomplishing on-site data gathering and the time transmission domestic water quality detecting device based on gray scale identification.
In order to solve the problems of the technologies described above; The utility model provides a kind of water quality detecting device based on gray scale identification, comprising: be used to obtain the identification of water quality gray scale with the water quality camera of image, the video a/d module that links to each other with this water quality camera, the CPU that links to each other with the digital signal output end of this video a/d module, the video d/a module that links to each other with this CPU, the monitor that links to each other with the analog signal output of this video d/a module and the charactron circuit that is used for on-site real-time demonstration water quality condition that links to each other with said CPU.
One side of said water quality camera is provided with light source.
