Technical Field

The invention relates to a device for monitoring dissolved oxygen in water, in particular to a dissolved oxygen sensor capable of automatically adjusting the height.

Background

Dissolved oxygen is one of the important parameters of water quality, and represents the strength of the self-cleaning capacity of the water body, and the content of the dissolved oxygen in the water is mainly influenced by two aspects, namely the consumption of the dissolved oxygen in the water, the consumption is mainly caused by the degradation of organic matters and the respiration of organisms in the water, and the concentration of the dissolved oxygen is increased by photosynthesis in the water and the dissolution of air oxygen. The concentration of dissolved oxygen in water is different along with the depth of water, and particularly, the situation that the concentration of dissolved oxygen on the surface layer of a water body is saturated and the bottom is anaerobic exists at the bottom of a culture water bottom with more deposited organic matters.

Dissolved oxygen is essential for aquatic organisms, and in aquaculture, when the dissolved oxygen concentration is lower than 4mg/L, the fish population is suffocated and killed. Different fish live in different water layers and even the same fish may accumulate in different water layers at different stages of growth. Therefore, according to the water layer where fish school live, it is very necessary to detect the dissolved oxygen in different water layers at any time. At present, however, few dissolved oxygen sensors can intelligently detect dissolved oxygen in different water layers, the water layers detected by the sensors are mainly based on the placement depth of farmers, and if the placement positions of the farmers are not appropriate, fish schools can die.

The CPU processor processes and analyzes the picture information transmitted by the camera module, determines the water layer where the fish school is located, and enables the sensor to ascend or descend to the water layer where the fish school is located by starting the lifting module. When the device arrives at the water layer where the shoal of fish is located, the dissolved oxygen sensor module immediately starts the dissolved oxygen sensor and the temperature sensor detects the temperature and the dissolved oxygen concentration of the water layer where the shoal of fish is located, transmits the data of the temperature and the dissolved oxygen to the CPU through the 485 bus for processing, and transmits the data to the shore through an external data line for displaying and alarming.
