Carrier rocket control system ignition sequence circuit

[0015] The present invention will be further described below in conjunction with drawings and embodiments.

[0016] like figure 1 , The ignition timing circuit provides a signal source for the ignition on the arrow, and it is given by three highly reliable programmable controllers. In order to improve the reliability and not cause misfire, a two-out-of-three redundant design is implemented for the ignition start signal. When the PRGI controller receives the ignition start signal, its controller sends out the ignition timing signal relay device in an orderly manner, respectively. Connect K 11, A, B, C, and then provide the ignition timing signal to the arrow in a redundant way out of three.

[0017] like figure 2 , the emergency shutdown circuit is t seconds after the rocket is ignited. If the rocket has not yet taken off, then the circuit will implement an emergency shutdown on the ground. The circuit is also given by the same high-reliability programmable controller. The K21
