NOT gate control relay interlocking circuit

The invention provides a NOT gate control relay interlocking circuit. The NOT gate control relay interlocking circuit comprises: a first execution relay and a second execution relay, and a first NOT gate circuit, a second NOT gate circuit, a third NOT gate circuit and a fourth NOT gate circuit, wherein the first NOT gate circuit and the second NOT gate circuit are connected with the first execution relay, the third NOT gate circuit and the fourth NOT gate circuit are connected with the second execution relay, and corresponding actions of the execution relays are realized by adopting heterogeneous hardware circuit design. Devices of the non-gate circuits are all conventional components, engineering implementation is easy, and the function of at most one output power supply of the relay is achieved through control of the four non-gate circuits. 本发明提供一种非门控制继电器互锁电路，包括第一执行继电器和第二执行继电器；第一非门电路、第二非门电路、第三非门电路和第四非门电路，其中，所述第一非门电路、第二非门电路与第一执行继电器相连，第三非门电路、第四非门电路与第二执行继电器相连，采用异构的硬件电路设计，实现执行继电器的相应动作，本发明中非门电路的器件均采用常规元器件，易于工程实现
