Automatic monitoring method for oxygen dissolving in river

Abstract

The invention discloses an automatic monitoring method for oxygen dissolving in river. The method comprises the following steps: S1, a temperature sensor is used for collecting the real-time temperature of a river, a dissolved oxygen probe is used for collecting real-time data of dissolved oxygen in the river, and the collected data are sent to a PLC controller; S2, the PLC controller controls theworking state of an integrated circulation system by combining the real-time temperature, collected by the temperature sensor, of the river according to the real-time data of dissolved oxygen in theriver, and a control signal for controlling an oxygen supply unit is sent out to a solenoid valve; and S3, the solenoid valve controls turning on or off of the oxygen supply unit according to the control signal of the PLC controller. According to the invention, automatic monitoring and control of the dissolved oxygen in the river is realized. The structure is excellent, the practicability is high,the operation is simple, the maintenance becomes convenient, and the production and application costs are low. The automatic monitoring method can be applied to the detection industry of the dissolved oxygen in river.

Description

technical field [0001] The invention relates to the field of automatic detection of river dissolved oxygen, in particular to an automatic monitoring method for river dissolved oxygen. Background technique [0002] In the south of China, most cities in South China have inland river surges, most of which are typical tidal river sections, controlled by sluice gates. River surges have the characteristics of complex distribution, small water capacity, and poor water fluidity. Once the water body is polluted, it is difficult to recover. In recent years, the pollution of rivers in our country has been increasing day by day, and the phenomenon of black and odor is serious. The color of the water body is black and the smell is smelly, which seriously affects people's living environment. Difficulty in controlling river gushing water has become one of the main obstacles to eliminating black and odor. Dissolved oxygen in river water is the lifeblood of black and odorous water manageme...

AI Technical Summary

Problems solved by technology

Dissolved oxygen monitoring technology started late, and the technology is relatively weak. It is rarely used in river surge management. Most of them use traditional methods, on-site sampling, and manual monitoring, which greatly increases the actual workload of river surge control. The cost of actual treatment has been reduced. On this basis, more costs are needed to realize the control of river dissolved oxygen.
