In view of the requirements that flight vehicle ignition control software is not suitable for purchasing commercial components and needs customized development， the ignition control principles of flight vehicles are studied. The ignition control processes of various flight vehicles are abstracted， and an ignition control software component based on parameters and actions is designed. These subcomponents can cooperate with each other， and the component needs parameters which reflect the characteristics of control process. This component can adapt to the ignition requirements of different systems and realizes the core function of ignition control software， which can reduce the software development cost and improve software quality efficiently in the meantime.
