One-key sequence control requires double confirmation of non-homologous signals for switching operation, and the two signals indicate that a certain knife switch is in a closed state and are only considered to be in the closed state, so that the operation is safer. In this embodiment, a video image recognition mode is adopted as the second criterion, and the first criterion is obtained by the main and auxiliary systems through other approaches, such as: the first criterion adopts position remote signaling, and is generally an auxiliary switch on-off contact.
