This invention relates to the field of temperature sensor testing, specifically the application of testing and measurement technology in the control of microclimates in
aquaculture. The method involves deploying a sealed
reference cavity with a built-in standard
thermometer in a forest-based
aquaculture area. Each temperature
sensor node is periodically inserted into the
reference cavity to periodically read the current temperature value and compare it with the standard
thermometer to obtain the absolute drift. A two-dimensional drift matrix is constructed by combining this data with historical
humidity data of the location. During non-calibration periods, the original temperature values are corrected using the two-dimensional drift matrix. The corrected temperature values are then used in a
Kriging space interpolation
algorithm to generate a three-dimensional temperature field distribution map. Based on the coordinates of local high-temperature areas in the distribution map, the corresponding
spray cooling solenoid valves are activated. This invention offsets the long-term drift caused by the high-
humidity and corrosive environment of the forest
undergrowth, corrects the spatial deviation of the original temperature data, improves the accuracy of the three-dimensional temperature field reconstruction, and avoids control misalignment caused by temperature
field assessment distortion.
