Base on the analyses of essential characters and harm of fire to equip and depot,the infective factors of fire catching and developing were studied with the considering of the active instance and the running rule of ammunition depot.

Through the analysis of inspection and test results of lightning proof safe facilities and equipments of a certain ammunition depot,deficiency and problems are found in the construction and setting of lightning proof safe facilities such as geographic position,lightning proof device,grounding device,and height of safe lightning conductor based on formula.

The acquisition of economy energy medicinal materials storehouse inside and outside difference in temperature is realized by using singlechip integration simulation temperature sensor AD590,which are made by Analog Devices Company,and it have value low,volume small,no need assistant electrical source,linearity good,periphery circuit simpleness.
