Zusammenfassung:The present invention is to provide a distributed antenna system which can automatically detect an abnormally operating remote unit. A node unit of a distributed antenna system, according to one embodiment of the present invention, comprises: a signal input part which receives and outputs n items of state information from n connected different units; and a control part which determines the states of uplink signals corresponding to the respective n items of state information by analyzing the n items of state information, wherein n is a natural number greater than or equal to 2, and the different units can generate the state information by analyzing signals received through a service antenna. The present invention can provide a distributed antenna system which can automatically detect an abnormally operating remote unit. L'invention concerne un système d'antennes distribuées qui peut détecter automatiquement une unité distante fonctionnant anormalement . Selon un mode de réalisation de l'invention, une unité de noeud de système d'antennes distribuées, comprend : une partie entrée de signal qui reçoit et délivre en sortie n éléments d'informations d'état à partir de n unités différentes reliées ; et une partie commande qui détermine les états de signaux de liaison montante correspondant aux n éléments d'informations d'état respectifs en analysant les n éléments d'informations d'état, n étant un nombre naturel supérieur ou égal à 2, et les différentes unités pouvant générer les informations d'état par analyse des signaux reçus par l'intermédiaire d'une antenne de service. L'invention peut fournir un système d'antennes distribuées qui peut détecter automatiquement une unité distante fonctionnant anormalement. 본 발명은 비정상적으로 동작하는 리모트 유닛을 자동으로 검출할 수 있는 분산 안테나 시스템(Distributed Antenna System)을 제공하기 위한 것이다. 본 발명의 일 실시예에 따른 분산 안테나 시스템의 노드 유닛은, 연결된 n개의 타유닛 각각으로부터 n개의 상태정보를 수신하여 출력하는 신호입력부 및 n개의 상태정보를 분석하여 n개의 상태정보 각각에 대응되는 업링크신호들의 상태를 판단하는 제어부를 포함하되, n은 2 이상의 자연수이고, 타유닛은 서비스안테나를 통해 수신된 신호를 분석하여 상기 상태정보를 생성할 수 있다. 본 발명에 따르면, 비정상적으로 동작하는 리모트 유닛을 자동으로 검출할 수 있는 분산 안테나 시스템(Distributed Antenna System)을 제공할 수 있다.
