摘　　要：从信号输入电路和输出控制电路两方面详细介绍了提高点火控制器可靠性和保证其安全性的设计;对堵片信号输入过程中等离子火焰电阻的影响进行了抑制,针对点火前、点火过程中以及点火后能够影响点火电路的不稳定因素采取了保护和防止措施;该点火控制器已经在靶场试验中进行使用,其高度的可靠性和安全性保证了分离控制任务的顺利完成。The design aiming at improving the reliability and ensuring the safety of ignition controller is elaborated from two aspects： sig nal input circuit and output control circuit. The effect resulting from plasma flame resistance in the process of block--chip signal input is re strained. Moreover, contraposing unstable factors produced before ignition, in ignition and after ignition, especially some factors influencing ignition circuit, it has taken some protective and preventive measures. This ignition controller has been used in the experiments in shooting range, and its high reliability and safety guarantee the successful completion of the separation task.
