PLATFORM DOOR STRUCTURE INSTALLING AND MANUFACTURING METHOD OF THE PLATFORM FENCE

摘要

The present invention relates to a door control system for a door control system, which comprises a first door unit installed on a platform as one of a plurality of door units, and a confirmation signal generation unit for generating a confirmation signal for outputting an acknowledgment signal for confirming the open / closed state of the gate space by the first door unit, And a return circuit for forming a closed loop circuit for defining a propagation path of a signal having a start point and an end point as an acknowledgment signal generation unit in cooperation with the first door unit and the confirmation signal generation unit. If the condition is normal, the first door unit closes the closed loop circuit and permits the transfer of the confirmation signal to the return circuit. The return circuit returns the confirmation signal received from the first door unit to the confirmation signal generation unit.
