the automatic image identification and the posture induction identification are used for capturing and analyzing the opening and closing state of the knife gate;
when the on state is judged, if any judgment disconnecting link in the second confirmation mode is on, the mode judged to be on and the first confirmation mode carry out second confirmation together, and if the first confirmation mode is also on, the next step is executed;
when the off state is judged, if any one of the second confirmation modes judges that the disconnecting link is off, the second confirmation is carried out by the mode of judging that the disconnecting link is off together with the first confirmation mode, and if the first confirmation mode is off, the next step is executed;
after the instruction is executed, judging whether the operation in the step meets the confirmation condition;
if the confirmation condition is met, the execution is continued, if the confirmation condition is not met, the execution operation is automatically suspended, and an error is prompted, and the error is manually confirmed and then is selected to be retried, ignored or terminated.
9. The method for controlling ice-melting switching-on-key sequence control according to claim 8,
the one-key sequential control operation order comprises information of an operation object, a current equipment state, a target equipment state, an operation task name, an operation item, an operation condition and a target state;
the operation ticket library is arranged in the scheduling end system, and the scheduling end system can generate, modify, delete, record and maintain logs of the operation tickets and perform self-checking.
10. The ice-melting switching-over one-key sequential control method as claimed in claim 8 or 9, characterized in that when the operation task is generated, the current operation condition list and the target state list are updated simultaneously;
the operation condition list is summarized and arranged according to the equipment name label;
the target state list is summarized and arranged according to the sequence of the operation items;
and matching with the one-key sequence control task to carry out the operation order combination of the subtasks, judging whether the current equipment state of the next operation task is met or not on the basis of the simulation result generated by the previous operation task by the one-key sequence control task combination, and if not, prohibiting the task combination.
