Refrigerator van temperature field actually-measured data visualization processing method and system

Abstract

The invention discloses a refrigerator van temperature field actually-measured data visualization processing method and system. The method comprises the steps of firstly, collecting temperature parameters of each layer of layout of various kinds of cargo packaging in different multi-layer stacking modes, obtaining a temperature contour line graphic set of each layer of cargos according to the obtained temperature parameters, and finally, determining the stacking scheme of the next cargo packaging according to the temperature contour line graphic set of each layer of cargos. According to the refrigerator van temperature field actually-measured data visualization processing method and system, the map counter line method is utilized for drawing counter lines, the situation of temperature field changes caused by different stacking modes can be seen clearly, and the data visualization can be achieved; the cargos are stacked in a layering mode no matter what method is adopted, the three-dimensional problem is converted into a two-dimensional problem, and the three-dimensional characteristics are not lost. Due to the fact that the discrete data meshing and the interpolation algorithm are adopted, the estimated temperature value of a non-sampling area can be obtained and basically conform to the practical situation. Actually-measured data are stored by the adoption of the layering thought, the logic stored in a database is more clear, and historical data are conveniently filed, retrieved and used.

Description

technical field [0001] The present invention relates to the data processing of the measured data of the temperature field of the refrigerated car, and in particular to a method and system for visualizing the measured data of the temperature field of the refrigerated car. Height temperature distribution images, so as to obtain scientific advice on the layer height and stacking method of different types of goods. Background technique [0002] Existing refrigerated vehicles generally have a single air outlet. Even for refrigerated vehicles with multiple air outlets, the temperature of each part of the compartment is different, and even when fully loaded with goods, there will be a large temperature difference. Due to the fact that agricultural products often need to be mixed with multiple fresh varieties during the logistics loading process, different varieties have different optimal storage and transportation temperatures. Therefore, researchers have tried various modeling pr...

Problems solved by technology

Therefore, researchers have tried various modeling processes for refrigerated cars, and even used complex 3D modeling software to simulate the temperature field in refrigerated cars. Under the conditions of various stacking methods, such as the four most common methods of "pin type", "well shape", "123321" type, and "basket mouth paired" type, the temperature field in the compartment changes significantly. Yes, even if the sensor is deployed to measure the temperature data of several points

Failure to understand the changes in the temperature field in the compartment behind the stack will lead to the setting of the temperature switch being too high or too low, resulting in low efficiency in logistics storage and transportation of agricultural product refrigerated vehicles, wasting a lot of energy, and even causing rot and frostbite of agricultural products.
