The invention discloses a remote ignition device suitable for a solid rocket engine and an ignition method. An upper computer is arranged outside an ignition safety distance; the lower computer is arranged in a rocket launching vehicle, the lower computer is in communication connection with a rocket engine, and the upper computer and the lower computer are in communication connection through an optical transceiver; the ignition method comprises the following steps: setting an IP address and a network port number of a lower computer, and connecting a network; testing whether upper and lower computer communication is normal; self-checking the lower computer, and determining whether a first power supply and a second power supply of the lower computer are normal or not; testing whether an engine safety mechanism is in a safety state; testing whether the ignition loop is normal; an engine safety mechanism is unprotected; igniting the engine; ignition personnel can send instructions to the lower computer through the upper computer several kilometers away, engine access resistance detection, engine safety mechanism reprotection and engine ignition are achieved, and safety threats caused by abnormal explosion of the engine to ignition control personnel can be effectively avoided.
Description
technical field [0001] The invention relates to the technical field of embedded control, in particular to a remote ignition device and an ignition method suitable for a solid rocket motor. Background technique [0002] The working process of a solid rocket motor is an extremely complex physical and chemical process, which generally includes the ignition boost section, the stable working section and the pressure drop section. Ignition is the first step in the work of a solid rocket engine. The engine is first started by an ignition device. The ignition boost stage is very short, usually a few milliseconds to several hundred milliseconds, but the working mechanism is complex, including combustion, flow and heat transfer. It is a solid rocket. The key stage of the engine's working process plays a vital role in the normal operation of the engine. Due to the very short time, harsh working environment, and drastic changes in physical parameters, the rocket engine is most prone to...
