Abstract:
(EN) The present invention relates to a technique by which an external congestion control server can receive passenger car-specific congestion information for a train so as provide information related to the level of congestion in each passenger car thereof to subway passengers waiting to board the train at a subway station, when a WLAN-based congestion detector provided in each passenger car of the subway train produces congestion information on how many passengers are in a passenger car on the basis of the fluctuation characteristics of WLAN parameters of an inner passenger car space. The present invention is configured such that the congestion detector is composed of a plurality of WLAN devices in order to increase estimation accuracy when the congestion information is produced, and an inner wireless communication environment of the subway passenger car is stabilized by continuously transmitting and receiving dummy data therebetween in the form of a UDP packet.
(FR) L’invention concerne une technique permettant à un serveur de commande d’encombrement externe de recevoir des informations d’encombrement spécifiques à un wagon d'une rame afin de fournir des informations relatives au niveau d’encombrement dans chaque wagon de celle-ci aux passagers du métro qui attendent de monter dans la rame dans une station de métro lorsqu'un détecteur d’encombrement basé sur un WLAN prévu dans chaque wagon de la rame de métro produit des informations d’encombrement sur le nombre de passagers présents dans un wagon d’après les caractéristiques de fluctuation des paramètres WLAN d'un espace de wagon interne. L’invention est configurée de façon à ce que le détecteur d’encombrement soit composé d'une pluralité de dispositifs WLAN afin d'augmenter la précision d'estimation lorsque les informations d’encombrement sont produites et de façon à ce qu’un environnement de communication sans fil interne du wagon de métro soit stabilisé en transmettant et en recevant en continu des données fictives sous la forme d'un paquet UDP.
(KO) 본 발명은 지하철 열차의 객실마다 설치된 무선랜 기반의 혼잡 감지기가 객실 내부 공간에서의 무선랜 파라미터의 동요 특성에 기초하여 해당 객실에 승객이 얼마나 있는지 혼잡도 정보를 산출하면 외부의 혼잡도 관제 서버가 해당 열차에 대한 객실별 혼잡도 정보를 제공받아 지하철 역에서 해당 열차를 탑승하려고 대기하는 지하철 이용객들에게 각 객실별로 얼마나 혼잡한지에 관한 정보를 제공할 수 있는 기술에 관한 것이다. 이때, 본 발명에서는 혼잡도 정보를 산출할 때 그 추정 정확도를 높이기 위해 혼잡 감지기가 복수 개의 무선랜 디바이스로 구성되고 이들 간에 더미데이터를 UDP 패킷의 형태로 지속적으로 송수신함으로써 지하철 객실 내부의 무선통신 환경을 안정화시키도록 구성된다.
