研究了基于三冗余控制方案的推进剂利用系统液位信号采样的原理,深入分析了系统试验中液位信号采集故障的问题,进一步采用了一种基于周期延时的行末点换行策略,彻底解决了三冗余状态下由不同步带来的液位信号采集故障问题。
Based on the principle of three-redundant control scheme, the principle of using the system liquid level signal sampling of the propellant is analyzed. The problem of liquid level signal acquisition fault in the system test is analyzed in depth. A line-end line-changing strategy based on periodic delay is further adopted. Solve the problem of signal acquisition failure caused by the non-synchronization of the three redundant states.
