MODULAR-CHASSIS-APPLIED RACK-MOUNT ANNOUNCEMENT APPARATUS TO BE USED IN SUBWAY STATION

摘要

The present invention relates to an announcement apparatus for transmitting and announcing a variety of information in a station such as a subway. More specifically, a monitor of an input/output unit is foldable and retractable from a tray. Each unit of a controller is integrally formed in a card type so as to be individually detachable from a modular chassis having slots arranged in a horizontal direction, thereby achieving improvement from a vertical-stack type rack-mount structure to a modular-chassis-applied composite structure. A vertical space occupied by the entire apparatus is significantly reduced through miniaturization and horizontal arrangement of each unit constituting an existing control unit, thereby achieving miniaturization and weight reduction of the apparatus. Each unit for constituting the control unit is connected to the modular chassis in the card type, and each unit is simultaneously connected to a connecting substrate of the modular chassis. In this way, all units are connected together by a cable connection to the connecting substrate, instead of an individual cable connection to each unit. Accordingly, it is possible to minimize a cable for the backside of the announcement apparatus and perform a wiring work conveniently and simply. It is possible to reasonably solve problems such as a noise caused by an existing cable interference. Since a large number of units can be integrated by using the single-unit modular chassis, it is possible to remarkably reduce manufacturing costs of the apparatus and also significantly reduce a manufacturing time of the apparatus.;COPYRIGHT KIPO 2016
