and the secondary signal output unit is used for sending a signal to the linkage mechanism of the side guide plate to enable the linkage mechanism of the side guide plate to move towards the first direction based on the secondary motion amount, so that the final opening degree of the side guide plate reaches the specified target opening degree from the real-time opening degree.
10. The system of any one of claims 6-9, further comprising:
the motion amount monitoring module is used for monitoring the motion amount of the linkage mechanism of the side guide plate;
the matching module is used for comparing the monitored exercise amount with the inquired exercise amount;
and the warning module is used for prompting an error if the matching result of the matching module is not matched.
