System for monitoring dissolved oxygen in different water layers

Abstract

According to the different water layer dissolved oxygen monitoring system, an encoder is arranged at the tail of a driving motor, the driving motor is driven by a motor driver, a cylinder body of the driving motor is fixed to a motor support, a rotating shaft of the driving motor is connected with a clamping table of a wire storage and pay-off reel, and a data wire is wound around an annular groove in the middle of the wire storage and pay-off reel; one end of the data line is connected with the digital dissolved oxygen sensor and the digital liquid level sensor, and the other end extends out of the wire storage pay-off reel through the wire outlet cavity and then is connected with the acquisition card. The touch screen sets a depth set value h0, the digital liquid level sensor monitors an actual depth value h, and when h is smaller than h0, the controller controls the motor driver to drive the driving motor to rotate, drive the wire storage and pay-off reel to rotate, pay off a data wire and drive the digital dissolved oxygen sensor and the digital liquid level sensor to descend. The digital dissolved oxygen sensor continuously monitors the dissolved oxygen content of different water layers and transmits the dissolved oxygen content to the controller, and when h reaches h0, the controller controls the motor driver to stop driving the driving motor.

Description

Technical field [0001] The present invention involves the field of dissolving oxygen monitoring equipment technology, especially in different water layers to monitor different water layers to monitor different water layers monitoring systems that monitor different water layers, reduce costs, operate conveniently, and automatically regulate water layers through a dissolved oxygen sensor. Background technique [0002] The molecular oxygen dissolved in the air is called dissolved oxygen in water. The content of dissolved oxygen in water is closely related to the pressure of oxygen in the air and the temperature of the water. In natural cases, the oxygen content in the air does not change much, so the water temperature is the main factor. The lower the water temperature, the higher the content of dissolving oxygen in water. The molecular oxygen dissolved in the water is called dissolved oxygen, which is usually recorded as DO, and it is represented by the milligram of oxygen per lite...

AI Technical Summary

Problems solved by technology

The existing dissolved oxygen monitoring in different water layers generally uses dissolved oxygen monitors fixedly installed in different water layers for monitoring. This method requires the use of multiple dissolved oxygen monitors, and the price of dissolved oxygen sensors is high, and dissolved oxygen probes need to be replaced regularly ,higher cost
