Description
Technical field[0001]The present invention relates to the technical field of circuit design, in particular to a detonation control system and control method based on RC delay.Background technique[0002]The pyrotechnic device must be detonated by voltage transient, and the voltage is not allowed to have a long-term slow change process, which causes the half-start state of the components to be very dangerous.[0003]One of the key technologies of the delay initiation control circuit is the generation of microsecond step level. There are many methods of delay generation of delay circuit, such as using CPLD chip delay, single-chip programming delay, 555 timer delay and so on. At present, there are many chips that cannot be made in China. In addition, the above-mentioned chips are packaged in ceramic or metal packages, which cannot be used in harsh environments such as impact resistance and high overload.Summary of the invention[0004]The present invention provides a detonation control syste...
