| Abstract: | Designed a set of attitude control engine arc ignition system which took STC15W404S microprocessor as control core. The system uses 74HC4514 decode latch to extend single ship microcomputer I/O port, and adopts mono-stable circuit to realize timed control of ignition switch circuit. Realize real-time synchronization ignition among multi attitude control engines. At last, designed a watchdog reset, and increased the reliability of the system. Reached the design purpose, and had some practical value. |
