Description

Technical Field

[0001] The utility model relates to the technical field of indoor breeding supervision, and in particular to intelligent inspection equipment for indoor breeding. Background Art

[0002] Indoor farming is a farming method with broad development prospects. By rationally selecting farming types, optimizing the farming environment, and fine management, efficient, environmentally friendly, and sustainable farming production can be achieved.

[0003] The specific advantages of indoor farming include: environmental control. Indoor farming can achieve precise control of environmental factors such as temperature, humidity, light, ventilation, etc., providing a stable and suitable growth environment for farmed organisms; year-round production. Since the indoor environment is not affected by seasons and weather, uninterrupted production can be achieved throughout the year, thereby improving economic benefits; reducing the spread of diseases. By controlling the indoor environment, the spread of diseases can be reduced and farming risks can be reduced; improving yield and quality. Stable environmental conditions are conducive to the growth and development of farmed organisms, thereby improving yield and quality.

[0004] The types of indoor farming mainly include aquaculture, livestock and poultry farming, and insect farming. Among them, aquaculture is the most complicated compared to other types of indoor farming. The reason is that aquaculture has higher requirements for environmental conditions and more water quality parameters need to be controlled in aquaculture, including temperature, pH value, dissolved oxygen, ammonia nitrogen, nitrite, etc. These parameters are essential for the growth and survival of aquatic organisms. In contrast, other indoor farming such as livestock and poultry farming mainly focuses on temperature, humidity and ventilation. In addition, diseases in aquaculture spread quickly and are difficult to control. Aquatic organisms usually live in high-density environments. Once a disease occurs, it is easy to spread quickly, causing huge losses to farming.

[0005] In order to ensure the safety of aquatic products, when aquaculture is carried out indoors, it is necessary to sample the water in the aquaculture pond by inspection, so as to promptly discover and solve problems in the aquaculture process. In the prior art, the farm managers usually conduct sampling surveys or unified sampling tests on the aquaculture ponds. However, for large-scale indoor aquaculture farms, the inspection process is inefficient and has high labor costs. Utility Model Content

[0093] Through the above technical solution, this embodiment provides a process for preprocessing the state information data. Specifically, firstly, the abnormal state risk value Risk of the aquaculture pond 3 is calculated by formula (1)-(2), and then the abnormal state risk value is compared with the preset threshold R cap Compare: When Risk>R cap When Risk≤R cap When , it means that the difference between the water temperature and dissolved oxygen content in the aquaculture pond 3 and the preset standard is small, so the corresponding aquaculture pond 3 is judged to be in normal state. It should be noted that in formulas (1)-(2), T(t) is the time-varying value of the water temperature in the aquaculture pond 3 obtained by the temperature sensor; D(t) is the time-varying value of the dissolved oxygen content in the aquaculture pond 3 obtained by the dissolved oxygen online monitor; T st (t) is the standard curve of water temperature in the aquaculture pond 3, D st (t) is the standard curve of dissolved oxygen content in the aquaculture pond 3, which is obtained based on empirical data; ω1 and ω2 are preset weight coefficients, which are related to the type and density of aquatic products cultured in the aquaculture pond 3 and can be obtained by fitting experimental data, which will not be described in detail here.
