The article shows a new kind of power controller of micro-satellite. The controller is composed of charge control. Discharge control, shunt control and the equilibration circuit. The output voltage is stabilized by an automatic circuit controlled by the PWM signal, which is produced by comparing the sampling value of the output voltage with the reference voltage. The application indicates that the system which insured the safety property of Li-ion battery series runs stably as well as satisfied the need of the load no matter in what situation.

The system implemented forest fire model selection automatically and intelligently. BP artificial neural network model of forest fire model selection was build by treating forest fire environment data as inputting variable and treating appropriate forest fire model as outputting variable. At the same time, we studied the methods of acquiring and calculating data of inputting and outputting. The system implemented machine of model selection automatically based on dynamic data driven technology. We selected 72 items experimental data from historical forest fire records in Beijing to experiment and confirm the validity of model selection. It turned out that the reliability of model selection is more than 80 percent.
