Embodiment Construction
[0076] Please refer to figure 1 Shown is a schematic diagram of the redundant switching control circuit of the present invention. The logic circuit is mainly composed of a group of NAND logic circuits and a central processing unit, and realizes the exchange of logic state information of two logic objects A and B and the interlocking function of logic states. In this embodiment, two NAND logic circuits are used as a schematic illustration. The NAND logic circuits 1 and 2 correspond to logic objects A and B respectively, and have three input terminals. The first input terminals CON1 and CON2 transmit control signals, which are controlled by Central processing unit CPU1, CPU2 control; second input terminal RST1, RST2, transmit reset signal, controlled by the reset chip of logic object A, B, when logic object A, B is reset, the corresponding RST1, RST2 is low level.
[0077] The third input terminal STDBY1 of the non-logic circuit 1 transmits a state signal, and is connected with...
