Patent

CA 2267254

A method of recording events at stations (12) located at geographically separate locations across a large telecommunications network (10) is disclosed, together with event recorders (16) and a telecommunications system whereby the time-correlation of recorded events is greatly facilitated. Radio signals from an earth satellite system are used to generate precision time signals at each location and these time signals are used to time-stamp event locally recorded event data at each station (12). The recorded data and time- stamped data from each station (12) may then be downloaded to a control centre (20) and automatically arranged in time sequence with a precision of about one microsecond across the whole network.

La présente invention concerne une technique de consignation d'événements se produisant au niveau de stations (12) situées en des points géographiquement distincts dans toute l'étendue d'un grand réseau de télécommunications (10). L'invention, qui concerne également des dispositifs de consignation des événements (16), concerne aussi un système de télécommunications facilitant grandement la corrélation temporelle des événements consignés. En l'occurrence, les signaux radio provenant d'un système satellitaire terrestre servent à générer aux différents points géographiques des signaux temporels de précision qui permettent l'horodatage par chaque station (12) des données d'événements localement consignés. Les données consignées et les données horodatées provenant de chaque station (12) sont téléchargeables vers un centre de contrôle (20) et automatiquement classés chronologiquement avec une précision d'environ une ?s pour l'ensemble du réseau.
