7. The locomotive short access opening control method based on locomotive operation command as claimed in claim 6, wherein: and if the position of the linked hot metal mixer calculated by the locomotive running route control system is different from the actual position of the linked hot metal mixer, the locomotive running route control system sends out an error alarm.
8. The locomotive short access opening control method based on locomotive operation command as claimed in claim 6, wherein: if the position of the coupled torpedo hot metal mixer calculated by the locomotive running route control system is consistent with the actual position of the coupled torpedo hot metal mixer, and the states of the car coupler of the locomotive and the coupled torpedo hot metal mixer are accurate, the locomotive can execute coupling operation according to a coupling instruction issued by the running route control system until the car coupler of the locomotive and the car coupler of the coupled torpedo hot metal mixer complete coupling.
9. The locomotive short access opening control method based on locomotive operation command as claimed in claim 1, wherein: in the step of executing the unhooking instruction issued in the linked state, after the unhooking instruction is started, the locomotive running route control system judges whether the unhooking is finished after the alignment or the direct unhooking; if the locomotive is unhooked after the alignment is finished, the locomotive operation access control system can execute the unhooking action after receiving the signal of the completion of the alignment; if the uncoupling is directly carried out, the locomotive running route control system judges the positions of two car couplers needing uncoupling and the car coupler numbers, the locomotive running route control system issues uncoupling instructions to the corresponding car couplers, and the car coupler uncoupling system executes uncoupling actions.
