The invention provides a storage battery over-discharge protection and recovery signal generation circuit, which comprises at least three voltage comparison circuits, at least three self-locking circuits and at least one two-channel or two-channel multi-channel gating control circuit, and is characterized in that the three self-locking circuits are respectively connected with the two-channel or two-channel multi-channel gating control circuit; the three voltage comparison circuits are respectively connected with the corresponding self-locking circuits, a gating address line of Dout0 output of the two-channel multi-path gating control circuit is A, the input is S0A to S7A, a gating address line of Dout1 output of the two-channel multi-path gating control circuit is B, the input is S0B to S7B, and VOUT is output after the Dout0 output and the Dout1 output respectively pass through diodes. Two-out-of-three logic control is realized by adopting the multi-path gating switch, so that over-discharge protection and over-discharge recovery signals are reliably generated, the conditions of storage battery over-discharge or abnormal power failure and the like caused by circuit faults are avoided, and the reliability of the whole satellite is improved.
本发明提供一种蓄电池过放电保护及恢复信号发生电路,包括:至少三路电压比较电路、至少三路自锁电路和至少一路二通道或两路单通道多路选通控制电路,三路自锁电路分别与一路二通道或两路单通道多路选通控制电路连接,三路电压比较电路分别与对应的自锁电路连接,二通道多路选通控制电路的Dout0输出的选通地址线为A,输入为S0A至S7A,二通道多路选通控制电路的Dout1输出的选通地址线为B,输入为S0B至S7B,Dout0输出和Dout1输出后分别经过二极管后输出VOUT。本发明采用多路选通开关实现三取二逻辑控制,达到过放保护及过放恢复信号可靠发生,避免了电路故障带来蓄电池过放电或异常断电等情况发生,提升了整星可靠性。
