A dissolved oxygen automatic control device for aquaculture

The utility model relates to a dissolved oxygen automatic control device for aquaculture, breed unit, its characterized in that including at least one: each unit is provided with the control box respectively, is provided with oxygenation pump and oxygenation pump control system subassembly and control system in the control box, and each is bred unit and is provided with the connecting pipe respectively, and the connecting pipe is connected with the oxygenation pump, and each is bred the unit and is provided with respectively and dissolves oxygen sensor, and control system include with each corresponding a plurality of processing chips of oxygenation pump control system subassembly of breeding the unit, compare with prior art, the utility model has the advantages of breed the dissolved oxygen survey sensing probe that is equipped with in the unit through the difference and carry out oxygen bearing survey to the sea water of breeding in the unit to transmit the numerical value that detects rather than carrying out contrastive analysis in the processing chip that links to each other to, thereby realize carrying out automatic regulation and control to the dissolved oxygen that the unit was bred to the built -in three wart swimming crabs that have different growth cycle.
