Simulation Study on the Optimization of Temperature Measurement Cable Layout in Rectangular Warehouse during Ventilation
This study investigated the changes in grain temperature during a seven-day ventilation process in a rectangular warehouse.It also explored the optimization of the cable layout for temperature measurement.Numerical simulation was used to compare the grain temperature monitoring performance of different cable layouts,and their trade-off were evaluated through error and cost analyses.The results showed that the maximum absolute error in temperature monitoring with the national standard cable layout was 0.70℃,and the root mean square error was 25.83%.Uniform arrangements with adjusted cable spacing achieved a balance between accuracy and cost.In contrast,heterogeneous layouts reduced the root mean square error of grain temperature monitoring to 22.23%,while further lowering costs.In addition,the study verified the applicability of the heterogeneous layout in warehouses of different sizes.The optimized heterogeneous cable layout shows potential for practical implementation and wider adoption.
