Title (EN) APPARATUS AND METHOD FOR WIRELESS GAS MONITORING
(FR) PROCEDE ET APPAREIL DE CONTROLE SANS FIL DE GAZ
Abstract:
(EN) The current invention discloses a wireless monitoring system (8). The system (8) has one or more monitoring devices (14). Each device (14) can transmit data to and receive messages from an output center (18) or alarm system (19). The output center can also transmit and receive messages. Both the output center (18) and each device (14) preferably have a transceiver (43) that enables both the transmission (42) and receipt (44) of messages. No remote terminal units or hardwiring is required for the system to function. The system is truly a wireless gas monitoring system (8). The system (8) may use low earth orbit satellite (22) technology, or licensed radio frequencies or any other means to wirelessly transmit and receive messages.
(FR) La présente invention porte sur un système (8) de contrôle sans fil. Ce système (8) possède un ou plusieurs dispositifs (14) de contrôle. Chaque dispositif (14) peut transmettre des données et recevoir des messages vers et à partir d'un centre (18) d'émission ou d'un système (19) d'alarme. Le centre d'émission peut également transmettre et recevoir des messages. Le centre (18) d'émission et chaque dispositif (14) possèdent, de préférence, un émetteur-récepteur (43) pour la transmission (42) et la réception (44) des messages. Des terminaux à distance ou un câblage ne sont pas nécessaires pour faire fonctionner le système. Ce système est bien un système (8) sans fil de contrôle des gaz qui peut utiliser une technologie de satellite (22) sur orbite basse terrestre, ou des radiofréquences autorisées, ou tout autre moyen de transmission et de réception sans fil de messages.
