Abstract

Système modulaire de répartition pour le contrôle du taux de grisou dans les fonds de mines où il y a danger de grisou. Le système comporte au moins un circuit de commande 3, 3n connecté par au moins un enregistreur à canaux multiples 2, 2n à tracé par points à un circuit d'alarme 1 et à un circuit de générateurs de ligne 7. L'enregistreur 2, 2n est connecté à un circuit automatique 10, qui par ses sorties communique avec un circuit d'appel de détecteurs 9 commandant l'entrée d'au moins un transopteur 8, 8n et avec un circuit de contrôle d'impulsions 6. Ce dernier circuit 6 communique avec un circuit de complément de temps 5 et il est connecté par sa sortie par au moins un circuit de synchronisation automatique 4, 4n avec les entrées de tous les circuits de commande 3, 3n d'enregistreurs 2, 2n à tracé par points.Modular distribution system for controlling the firedamp rate in mine beds where there is a danger of firedamp. The system comprises at least one control circuit 3, 3n connected by at least one multi-channel recorder 2, 2n with a plot line to an alarm circuit 1 and to a line generator circuit 7. The recorder 2, 2n is connected to an automatic circuit 10, which by its outputs communicates with a detector calling circuit 9 controlling the input of at least one transopter 8, 8n and with a pulse control circuit 6. The latter circuit 6 communicates with a time complement circuit 5 and it is connected by its output by at least one automatic synchronization circuit 4, 4n with the inputs of all the control circuits 3, 3n of recorders 2, 2n with dot plot .
