Abstract
The invention provides a far-end time synchronization igniting control circuit used for launch control equipment and a control method thereof so that long-distance time synchronization control igniting can be realized and long-distance manual control igniting can also be realized. When time synchronization signal igniting is adopted, a time synchronization signal is inputted to the preceding state of a solid-state relay so that power supply paths of an electromagnetic relay K2 and an electromagnetic relay K1 which are connected at the succeeding stage are conducted in turn, and igniting excitation is transmitted to an igniting output circuit; and when manual control igniting is adopted, on/off of the power supply path of the electromagnetic relay K1 can be controlled by applying a set of momentary self-locking button switches, and igniting excitation is transmitted to the igniting output circuit. With application of the circuit, manual control can be selected or the time synchronization signal can be inputted at the launch control rear-end equipment so that front-end equipment can be controlled to perform igniting control, and thus time delay of igniting time can be effectively avoided.
