A frequency addressable ignitor control device utilizes electronic bandpass filters tuned to a unique center frequency and bandwidth for each ignitor. Energy generated by the system's controller comprises one or more narrow pulses whose center frequency corresponds to one or more bandpass filter/ignitor assemblies and sufficient energy for activation. A plurality of bandpass filter/ignitor assemblies are connected in parallel in the system. The controller generates electrical pulses of different frequencies transferred to the plurality of bandpass filter/ignitor assemblies via a two wire ignitor bus. Bandpass filter/ignitor assemblies whose filter allows sufficient energy to pass to an ignitor bridge element initiates the ignitor's explosive charge. The controller generates energy to the ignitor with appropriate sequence of frequencies and delays resulting in the desired detonation of appropriate individual bandpass filter/ignitor assemblies in the desired sequential order each with the desired delays.

Frequency addressable ignitor control device

A smart ignitor control system has communications output electronic circuitry and communications input electronic circuitry. The communications output electronic circuitry generates output serial clock, data, and handshaking signals for communication with a master ASIC that is adapted to communicate with a smart ignitor. The communications input electronic circuitry inputs data and handshaking signals from a master ASIC. Smart ignitors are in circuit communication with the master ASIC via an ignitor bus. Optionally, additional circuitry digitizes analog voltages and waveforms from the ignitor bus and transmits the digitized data to an electronic information processor.
