Initiating explosive device control circuit and controller using same

Abstract

The invention provides an initiating explosive device control circuit and a controller using the control circuit. The control circuit comprises an initiating explosive device control branch or a plurality of initiating explosive device control branches connected in parallel, and the initiating explosive device control branches are used for controlling initiation of an initiating explosive device. Each initiating explosive device control branch comprises an initiating explosive device bridge wire or a plurality of initiating explosive device bridge wires connected in parallel, the public plus ends of all the initiating explosive device control branches are connected with the plus end of a power source through a first control switch, the public minus ends of all the initiating explosive device control branches are connected with the minus end of the power source through a second control switch, and the first control switch and the second control switch are used for controlling on-off of the initiating explosive device control circuit; each initiating explosive device control branch further comprises an initiation switch used for controlling on-off of each initiating explosive device control branch. The initiating explosive device control circuit and the controller have the advantages that false operation of the initiating explosive device can be effectively avoided, and reliability and safety of the initiating explosive device control circuit are ensured.

Description

technical field [0001] The invention relates to the technical field of satellite pyrotechnics control, in particular to a pyrotechnics control circuit and a controller using the control circuit. Background technique [0002] The traditional pyrotechnic control circuit of the satellite, no matter from the design point of view or the intermediate test link, has a relatively large margin and complicated intermediate links, and often replaces some components before entering the launch site. This method has a relatively large share of current miniaturized satellite resources, and the disassembly of a single unit affects the development progress of the satellite, which is not conducive to the improvement of the overall efficiency. Therefore, on the basis of ensuring reliability and safety, from the perspective of small satellites, The efficient and simple pyrotechnics control circuit is designed. Contents of the invention [0003] The technical problem to be solved by the prese...
