Embodiment 1
[0035] like figure 1 As shown, the intelligent dissolved oxygen self-regulating method for industrial fish farming according to the present invention comprises the following steps:
[0036] Step S1: Set the dissolved oxygen threshold: set the lowest threshold L and the highest threshold H of dissolved oxygen in the controller;
[0037] Step S2: Control the switch of the aerator rod according to the dissolved oxygen content: the dissolved oxygen probe detects the dissolved oxygen content in the culture pond in real time, if the dissolved oxygen content is ≤ L, the system automatically turns on the emergency aerator rod; if the dissolved oxygen content > H , the emergency oxygen booster is turned off, leaving only the basic oxygen booster on;
[0038] Step S3: setting the emergency oxygenation command: setting the solenoid valve for controlling the emergency oxygenation rod to open and close once is the completion of the emergency oxygenation command, and record an emergency ox...
Embodiment 2
[0052] like figure 2 As shown in the figure, a system of an intelligent dissolved oxygen self-regulating method for industrial fish farming according to the present invention includes a dissolved oxygen probe, a basic oxygen booster, an emergency oxygen booster, a communication alarm system and a controller, wherein:
[0053] The dissolved oxygen probe is installed in the breeding pond to detect the dissolved oxygen content in the breeding pond in real time; the dissolved oxygen probe is connected to the data reading unit of the controller, and the dissolved oxygen content in the breeding pond is sent to the controller in real time through the data reading unit;
[0054] The basic oxygenation rod is set in the breeding pond and is always turned on to increase oxygen for the breeding pond;
[0055] The emergency oxygenation rod is set in the breeding pond, and when the dissolved oxygen content in the breeding pond is lower than the threshold value, it is turned on to perform e...
Embodiment 3
[0059] This example presents a set of specific examples through Atlantic salmon farming: such as image 3 As shown, the low threshold for dissolved oxygen was set to 95% and the high threshold was set to 110%. When the dissolved oxygen level drops to 85%, the basic oxygen supply unit alone cannot meet the dissolved oxygen requirements of the aquaculture water. At this time, the solenoid valve that controls the emergency aerator is opened, the emergency aerator is activated, and the dissolved oxygen level of the aquaculture pond rises. Under normal circumstances, the dissolved oxygen level fluctuates slightly within the threshold range, which basically does not trigger the activation of the emergency oxygen booster (after 16:00). During baiting (baiting every 3 hours, 3:00, 6:00, 9:00, etc.), there will be a short-term emergency oxygen rod opening, especially during the day when workers are conducting daily inspections, Atlantic salmon will appear excited, High oxygen consumpt...
