Abstract

A traffic supervision system for transport systems (17) of the type comprising a towing unit and one or more transporting or transported units, the towing unit having a data processing unit (1) with transmit and receive facilities adapted to read/write messages from stationarily located tags (10B) or to transmit information via a wireless transmission (7) in which the towed, transporting or transported unit or units have another data processing unit (15) having transmit and receive facilities capable of exchanging information with the data processing unit (1) in the towing unit via a wireless transmission (7) or via an interface (8).

Claims

1. A traffic supervision system for transport systems of the type comprising a towing unit and one or more transporting or transported units, said system comprising:

a data processing unit in the towing unit having transmit and receive facilities adapted to read/write messages from stationarily located transmit and receive facilities, the towed, transporting or transported units have another data processing unit having transmit and receive facilities capable of exchanging information with the data processing unit in the towing unit via a wireless transmission or via an interface wherein the transported unit or units have a first aerial capable of reading information from a tag which is located on the transporting unit.

2. A traffic supervision system according to claim 1, wherein the data processing unit of the towed, transporting or transported unit or units can additionally exchange information with local data processing units which are stationarily located outside the towing unit.

3. A traffic supervision system according to claim 1, wherein the transported unit or units have a tag from which and to which the data processing unit in the transported unit and the data processing system in the towing unit can receive and supply information related to the course of a transport concerned via an aerial in the transported unit and an aerial in the transporting unit.

4. A traffic supervision system according to claim 1, wherein the transporting or transported unit or units have a second tag which is located in the top of the unit.

5. A traffic supervision system according to claim 2, wherein the data processing unit of the towing unit and the stationarily located data processing units communicate with a satellite, GSM or GSP system.

6. A traffic supervision system according to claim 1, wherein sensors are connected to the data processing units of the transporting or transported unit or units.

7. A traffic supervision system according to claim 1, wherein the first aerial is adapted to read information from tags which are located outside the transporting or transported unit or units.

8. A traffic supervision system according to claim 1, wherein the transporting or transported unit or units have their own power supply.
