CONTROLLING SYSTEM FOR LONG CABLE INSTALLATION

摘要

PROBLEM TO BE SOLVED: To prevent the generation of mutual interferneces between different construction areas by allowing a plurality of control bards to collectively control the driving and stoppage of cable laying equipment by transmitting signals between arithmetic and storage units built in the control boards themselves or between those of a plurality of driving boards. SOLUTION: A construction area is devided into a plurality of spans 16a-16d, and cable-laying equipment 11-1 -11-48 are installed along a contraction route of a long cable 12 over the entire construction area. The laying equipment 11-1 -11-48 have built-in arithmetic and storage units such as a sequencer and microcomputer and are connected with respective drive boards 17-1 -17-48 which individually control the laying equipment 11-1 -11-48 respectively. One control boards is allocated to one span such that the other control boards cannot be specified for a span which has been specified by a certain control board. By this method, the driving and stoppage of the laying equipment 11-1 -11-48 can be controlled collectively.
