This article has established the temperature of granary space distribution law at the same time by least square method,and fore- casts the temperature law following time by fuzzy neural network controller, Now that such having reduced the upkeep cost, and the temperature of granary is controlled much better.

This paper discusses the finite element analysis method in course of monitoring temperature of the burn with a computer, the mathematical model is found and the diffusion rule method of the barn in temperature field is analyzed, thereby the optimal control of the burn temper is realized.
