DATA COMMUNICATING SYSTEM OF ELEVATOR

摘要

PURPOSE: A data communication system of an elevator is provided to check an unusual condition by checking an emergency interphone line for the safety of an elevator. CONSTITUTION: Interphone magnetism(110) is connected to an upper plate(120) of a car. The upper plate of the car controls the operation of an elevator car. A machine room main drive(130) controls the overall operation of the elevator car. An interphone master receiver(140) is operated by being connected to the interphone magnetism in an emergency interphone state. A DSLAM(Digital Subscriber Line Access Multiplexer)(150) communicates the interphone master receiver and the internet. An xDSL(x Digital Subscriber Line)-GATE(160) is installed between the upper plate of the car and a modem(170). The modem outputs a converted signal to an information and communication terminal by changing signals transmitted and received between an information and communication terminal(180) and the upper plate of the car.
