【Abstract】 Discusses in detail the theory behind the control circuits of pyrotechnic devices, the selection of components, measures taken to avoid explosion, tolerance of hardware and software fault and interference and redundancy technique. The safety design of small satellite and the reliability design of the whole circuits are tested at steps A, B, C and D by the whole design department of Beijing space aircraft. The measurements indicate that design is reasonable, run is proper, the solar panels are successfully deployed and the requisition is attained.更多还原
