CA 2567866

A pump control system for controlling a fluid pump powered by an AC signal. The pump control system includes a signal phase detector coupled to the fluid pump to detect the AC signal supplied to the fluid pump and to generate phase signals indicating a phase parameter of the AC signal. The pump control system also includes a micro-controller to receive the phase signals and to generate a rectified output signal based on the phase signals, and a relay to control the power supplied to the fluid pump based on the output signal of the micro- controller.

L'invention concerne un système de commande de pompe destiné à la commande d'une pompe à fluide entraînée par un signal de courant alternatif. Ledit système de commande de pompe comporte un détecteur de phase de signal couplé à la pompe fluidique de manière à détecter le signal de courant alternatif fourni à la pompe fluidique et produire des signaux de phase indiquant un paramètre de phase du signal de courant alternatif. Ledit système de commande de pompe comporte également un micro-contrôleur de manière à recevoir les signaux de phase et produire un signal de sortie rectifié sur la base des signaux de phase, ainsi qu'un relais de manière à commander le courant fourni à la pompe fluidique sur la base du signal de sortie du micro-contrôleur.
