The other end connection of product.
Utility model works principle is that when electric on guided missile, power supply relay movable contact is powered；When controller is to power supply
Relay sends connection power supply signal, and power supply relay is started working, and first, second movable contact is connected with normally opened contact, is lighted a fire
Power supply passes through power supply relay to ignition relay；Now the movable contact of ignition relay is in vacant state, even if point
Quick-fried instruction also can guarantee that priming system will not be by overdue quick-fried by false triggering；In MISSILE LAUNCHING, controller is sent to ignition relay
Power supply signal, ignition relay is worked after receiving instruction, and movable contact is connected with normally opened contact, firing circuit conducting, so as to put quick-fried
Priming system；
When controller to power supply relay sends disconnection power supply signal, power supply relay work, first, second movable contact with
Normally opened contact separate, ignition relay is not switched on power supply, and firing circuit is off, at the same the 3rd movable contact with it is normally opened
Contact, detection disconnects power supply signal end and connected with disconnecting power supply negative terminal, is controlled by the way that the connection of outside optocoupler Acquisition Circuit is outside
Device processed, the state of power supply relay is judged by peripheral control unit, ensures the safety of circuit.
By the contemplated above technical scheme of the utility model, using control signal realize to power supply in firing circuit after
The control of electrical equipment and ignition relay, by the two paths transmission of one line voltage of single ignition relay, realizes ignition signal
Redundancy output；And the priming system firing circuit monitors the state of power supply relay in real time, adds security insurance；The firer
Product firing circuit combines redundancy backup with detection circuit, the reliability of firing circuit is further increased, with higher
Practical value.
