The invention provides a dissimilar redundant insurance control circuit, which relates to the technical field of avionics, is applied to a throwing control box, and comprises a charging loop and a discharging loop, the charging loop and the discharging loop respectively comprise an energy storage capacitor, and the energy storage capacitors are connected with the charging loop and the discharging loop. And an aircraft safety catch signal and an aircraft wheel signal are respectively and simultaneously accessed into the charging loop and the discharging loop. A charging and discharging loop of the energy storage capacitor is controlled, it is guaranteed that the energy storage capacitor has no energy before an airplane takes off and the energy storage capacitor stores energy normally after the airplane takes off, the problem that a jettisoning recorder is jettisoned by mistake due to spurious triggering of jettisoning separation signals is effectively solved, meanwhile, redundancy control is achieved through safety catch signals and airplane wheel signals, and the jettisoning recorder is more stable in jettisoning. And the problem of failure of the safety control circuit caused by failure of a single signal is avoided, and the reliability is very high.

    本发明提供了一种非相似冗余保险控制电路,涉及航空电子技术领域,应用于抛放控制盒中,所述保险控制电路包括:充电回路和放电回路,所述充电回路和所述放电回路中均包括储能电容,且所述充电回路和所述放电回路分别同时接入飞机保险栓信号和飞机轮信号。本发明对储能电容的充放电回路进行控制,保证飞机起飞前,储能电容无能量,飞机起飞后,储能电容正常储能,有效避免因抛放分离信号误触发导致抛放记录器误抛的问题,同时利用保险栓信号与飞机轮信号冗余控制,避免因单一信号失效导致的保险控制电路失效的问题,具有很高的可靠性。
