Abstract
本实用新型涉及一种用于点火装置的离子探针式火焰检测系统,系统包括包括前置放大模块以及与其连接的运算处理模块;所述前置放大模块包括交流增益单元、离子探针、隔离保护单元、电流采样单元、信号叠加单元和基准电压源;所述离子探针与交流增益单元隔离保护单元连接;所述隔离保护单元、电流采样单元、信号叠加单元和基准电压源顺序连接;所述信号叠加单元与运算处理模块连接。本实用新型将采样电压与基准电压通过信号叠加单元进行叠加,有效实现了采样信号与处理单元的隔离,降低了处理单元受干扰破坏的风险。本实用新型可根据方波信号的参数,按照应用需求灵活设置延迟时间和灵敏度,提高了离子电流信号检测的适应性和可靠性
