Problems solved by technology

Because people have a certain reaction time, even if the operator performs the action according to the on-site scheduling time, the actual ignition time will be delayed to a certain extent compared with the specified time.
And due to the individual differences of people, the ignition delay of the power unit caused by different operators is also different.
In this case, the launch mission will be affected, resulting in the failure of the test purpose

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.

Description

technical field [0001] The invention belongs to the technical field of launch control, and in particular relates to a remote timing ignition control circuit for launch control equipment and a control method thereof. Background technique [0002] With the rapid development of electronic technology, the technical strength and functions of missile-borne equipment are increasing day by day. Considering the safety of personnel during operation, generally in the field of launch control, the launch control equipment will be arranged in a distributed form before and after, and the operator will issue instructions on the back-end equipment, and transmit them to the front-end equipment through the interconnection cable for reception and judgment. Afterwards, the corresponding control is executed according to the instruction, and the ignition of the power unit is implemented. [0003] In the technical literature "Missile Test Launch and Control System" published by Aerospace Press, th...
