Claims

Patent Claims

1. A remote control system comprising at least exchange and a plurality of substations, wherein at least some of the substations are formed by exchange stations which are equipped to emit messages, wherein the stations, each of which is provided with a call number, are connected with one another by at least one joint signal transmission network, and wherein the substations exchange information with the exchange in time sequence, characterised in that the signal transmission network is a combination of a main network (HNl, HN2) containing at least one exchange (Hi, H2) and several area networks (BN3 to BN6) which can be integrated either alone or in groups into the main network, further characterised in that one exchange station (Z3 to Z6) is provided per area network (BN3 to BN6) , and that one group of call numbers is allocated to the exchange stations (Z3 to Z6) while call numbers of a further group of call numbers are simultaneously supplied to the substations (U7/8, Ull, Ul6, U3', U12') of various area networks (BN3 to B 6) and that the transmission of the messages is effected by including the area network (BN3 to B 6) and by subsequent message _ emission from the substations (U21 to U30) of the area network (BN3 to BN6) directly to the exchange (Hi, H2) of the main network (HNl, HN2) .

2. A remote control system according to claim 1, characterised in that at least a number of exchange stations (Z3 to Z6) contains an area exchange which upon the presence of at least one predetermined message, which is to be transmitted from the particular area network (BN3 to BN6) to the exchange (Hi, H2) of the main network (HNl, HN2) produces a collective trigger which is transmitted by the exchange station to the exchange (Hi, H2) of the main network (HNl, H 2) .

3. A remote control system according to claim 1 or 2, characterised in that in at least one portion of the area network (BN3 to BN6) messages are picked up separatel in accordance with degrees of urgency, and that at least the messages of particular urgencies are transmitted in the form ,"· of a collective trigger from the exchange station to the exchange in accordance with their degree of urgency.

4. A remote control system according to claim 3, characterised in that in at least one portion of the area networks (B 2 to BN6) messages are picked up separately in accordance with their degree of urgency, and that messages of the first degree of urgency which may be present are transmitted from the exchange station (Z2 to Z6) as such, and that messages of other degrees of urgency which may be present are transmitted in the form of collective triggers to the exchange (Hi, H2) of the main network (HNl, H 2) .

5. A remote control system according to claim 4, characterised in that the substations (U21 to U30) of the area networks (BN2 to BN6) can be interrogated by the exchange (Hi, H2) of the main network (HNl, HN2) subsequent to a complete interrogated cycle of the stations (Ul to U18, Ul' to U121) of the main network.

6. A remote control network according to any one of claims 1 to 5, characterised in that substations of the remote control system which are provided to be triggered off simultaneously, may possibly be provided as separate substations in the exchange stations, and that this group of substations is allocated a joint call address.

7. Λ remote control system according to any one of the preceding claims, characterised in that the remote control system contains at least one additional remote control system, which is connected to the same main network and has its own audio frequency, when the first remote control system transmits remote control signals with the aid of audio frequency impulse telegrams.

8. Λ remote control system according to any one of the preceding claims, characterised in that an indicating device which is connected to the exchange (Hi* H2) of the main network (HNl, H 2) contains at least one portion which is common to a number of the area networks (B 2 to BN6) , and indicating means to indicate the area which has been selected in a particular instance.

9. A remote control system according to claim 8, characterised in that the indicating device which is connected to the exchange (Hi, H2) of the main network (HNl, H 2) contains a part which is designed to indicate the messages of a station and which is jointly provided for a number of stations of different areas, and also indicating means for a station as well as for an area signal.
