摘　　要：光电密码点火控制电路由光密码接收、光电转换、密码鉴别、单次试开、电容充放电单元及电源管理等部分组成。其能量通道和信息通道均采用光耦合实现,以提高点火系统经受电磁干扰能力。在点火系统中通过点火密码和点火部件的光电密码验证及单次试开功能后,将进一步提高点火的安全性。Optical code ignition control circuit consists of photoelectric code receiver, photoelectric converter, code discriminator, single unclosing unit, capacitor charge and discharge unit（CDU） and power supply unit. In order to improve anti-EMI capability of the ignition system, the energy channels and the communication channels are realized by photo electricity coupling. Adopted by the method of ignition code, photoelectric code verification and single unclosing, the safety of ignition system is highly improved.
