Abstract
(EN)
The present invention relates to a method for reducing detection data of a monitoring device in a vehicle, and a method for monitoring a vehicle defect in near real time using same. According to the present invention, an upper and lower value difference method or deviation method for reducing and restoring data without loss through a simple calculation using the fact that a variation in the detected data is not great is provided so that a monitoring system which monitors defects of all vehicles periodically transmits massive data detected from a plurality of running vehicles to a driving control center in order to monitor devices related to operations of all of the running vehicles in near real time. Measured data of each of the main devices of a whole vehicle, which are obtained by a sensor and indicate states of the main devices, can be reduced without data loss being transmitted by performing a simple calculation such as calculation of an average or deviation by using the upper and lower value difference method or deviation method. Therefore, network traffic due to the massive data transmitted from the plurality of running vehicles can be reduced, and the load on a server of the driving control center (due to data storing and processing operations) can thereby be remarkably reduced, and thus, the occurrence of defects in the main devices of the vehicles can be detected in close to real time.

La présente invention concerne un procédé permettant de réduire des données de détection d'un dispositif de surveillance dans un véhicule, et un procédé de surveillance d'un défaut de véhicule pratiquement en temps réel à l'aide du premier procédé. La présente invention concerne un procédé de différence entre des valeurs supérieure et inférieure ou un procédé d'écart pour réduire et restaurer des données sans pertes par le biais d'un simple calcul en utilisant le fait qu'une variation des données détectées n'est pas grande de sorte qu'un système de surveillance, qui surveille des défauts de tous les véhicules, transmette périodiquement des masses de données détectées parmi une pluralité de véhicules en marche à un centre de commande de conduite afin de surveiller en temps pratiquement réel des dispositifs concernant des opérations de tous les véhicules en marche. Les données mesurées par tous les dispositifs principaux d'un véhicule, qui sont obtenues par un capteur et indiquent des états des dispositifs principaux, peuvent être réduites sans perte de données lors de leur transmission en réalisant un simple calcul tel qu'un calcul d'une moyenne ou d'un écart à l'aide d'un procédé de différence entre des valeurs supérieures et inférieures ou d'un procédé d'écart. Par conséquent, l'invention permet de réduire un trafic de réseau dû aux données en masse transmises par la pluralité de véhicules en marche et, de cette façon, la charge (due aux opérations de stockage et de traitement de données) sur un serveur du centre de commande de conduite peut être remarquablement réduite et, ainsi, l'occurrence de défauts dans les dispositifs principaux des véhicules peut être détectée pratiquement en temps réel.

본 발명인 차량 내 감시장치의 검지데이터에 대한 데이터 축소 방법 및 그 방법에 의한 차량의 준실시간 결함 감시 방법으로서, 검지한 데이터의 변화폭이 크지 않은 점을 이용하여 간단한 연산에 의해 손실 없이 데이터를 축소하고 복원하는 상하치별차법 또는 편차법을 제공하여 차량 전체의 결함을 감시하는 모니터링 시스템에서 다수의 운행하고 있는 차량에서 검지한 방대한 데이터를 주기적으로 운행관제센터로 송신하여 전체 운행차량의 작동과 관련된 장치들에 대한 감시를 준실시간처리를 위한 차량의 결함 감시 방법을 제공하여 데이터의 손실 없이 평균과 편차와 같은 간단한 연산에 의한 상하치별차법 또는 편차법으로 데이터의 크기를 축소하여 전체 차량내 주요 장치의 상태에 대하여 센서에 의해 검지하여 전송할 장치별 측정 데이터를 축소하여 전송할 수 있어 다수의 운행차량으로부터 전송되는 대량의 데이터로 인한 네트워크 트래픽을 감소시키고 운행관제센터에서 데이터를 저장 및 처리함에 있어 발생하는 서버의 부하를 현격히 감소시켜 이들 주요 장치들에 대하여 준실시간으로 차량의 결함을 검지할 수 있다.
