ANTI-COLLISION SYSTEM FOR ENTERING REGIN IN STEEL STOCK YARD

摘要

Disclosed in the present invention is an anti-collision system for an entry area in a steel stock yard which is improved in order to increase productivity and minimize the number of observers by displaying the position of bays of a transferring means entering individual entry areas using a sensor, and a wireless module in a steel stock yard in order to be cautious only for the relevant sections indicated with entry. The anti-collision system for an entry area in a steel stock yard comprises: a plurality of bays which include a plurality of entry areas such that a plurality of cranes can move to perform work in each entry area; a first sensor and a second sensor installed at a fixed interval in each entry area in order to sense the entry of a vehicle; and a control unit which combines signals sensed by the first sensor and the second sensor in order to transfer an entry state signal to the crane. The control unit counts the accumulative number of vehicles which enter each entry area, and calculates the entry state signal of the vehicles based on the accumulative number of the vehicles. Therefore, the anti-collision system displays the position of bays of the transportation means entering the individual entry areas using the sensor and the wireless module in the steel stock yard to all overhead cranes in the steel stock yard in order to improve productivity, and minimize the number of observers by being cautious only to the relevant sections indicated with entry.
