METHOD FOR CENTRALLY PROTECTING A GROUP OF OBJECTS

The invention relates to alarm engineering and can be used for developing a centralised system for protecting non-movable objects. The inventive method consists in determining the state and the modification of the state for each object by means of an alarm system, in forming a control-diagnostic and alarm messages containing the object address and in converting said messages into hopping signals, in receiving the hopping signals transmitted by the alarm system of a protected object by one or several alarm systems of other protected objects of said group which are located within the range of capability limits of the alarm system device which transmits the hopping signals, in processing a hopping message contained in the received hopping signal with the aid of the alarm systems used in the form of hopping signal repeaters, in selecting a notification from the hopping message, in converting it into a standard message, in transmitting said message to the console terminal of a centralised protection guard station by means of a telephone network and /or a standard mobile communication cellular network, in selecting notifications from the processed received standard messages and in displaying them in a representative style. The inventive method makes it possible to simplify the centralised system for protecting a group of objects by avoiding the necessity of deploying base stations and repeaters for a regional mobile communication cellular network and to ensure the operation in the conditions of intentional interferences produced by penetrators by means of jammers. L'invention appartient au domaine de signalisation d'alarme et est destinée à la protection centralisée de sites immobiliers. Les installations de signalisation d'alarme permettent de déterminer l'état et le changement d'état de chaque site. On forme des messages de contrôle et de diagnostic ou d'alarme avec l'adresse du site, qui sont transformés en signaux de sauts. Les signaux de sauts transmis par une installation de signalisation d'alarme d'un site à protéger sont reçus par une ou plusieurs installations de signalisation d'alarme des autres sites protégés faisant partie du groupe à portée du système de transmission de l'installation de signalisation de protection ayant transmis le signal de sauts. Dans les installations de signalisation de protection qui ont un rôle de relais de transmission des signaux de sauts on effectue le traitement du message de sauts, contenu dans un message de sauts transm
