Through point position identification on multiple monitoring feedback data, multiple feedback row-column positions and multiple non-feedback row-column positions are determined. Based on preset point position connection data, association communication planning is performed. From the multiple feedback row-column positions, corresponding association communication positions having wired communication association with the multiple non-feedback row-column positions are selected.
