AI Technical Summary
Existing pyrotechnic ignition modules suffer from problems such as electromagnetic interference, electric arcs, and control signal jitter, and fail to collect data on the ignition status of pyrotechnics. They are also complex to design and costly.
An ignition execution, control, and signal acquisition circuit composed of a P-MOS transistor, optocoupler OC1, and optocoupler OC2 is used to realize the isolated control and status acquisition of pyrotechnic devices. The ignition status signal is transmitted to the main controller through optocoupler OC2.
It achieves isolation control and status acquisition of pyrotechnic devices, improves system safety, reduces costs, is highly adaptable, and can adjust the P-MOS transistor model according to the current requirements of pyrotechnic devices.
