Abstract

A cellular network data transmission system including a digital communicator having a memory in which data is stored and an automatic dialer at a specific location for responding to an electrical signal indicating a specific condition exists, a cellular interface connected to the digital communicator and a cellular transceiver having an antenna, connected to the cellular interface, a cellular network including a central computer and an antenna for receiving signals from the transceiver antenna and for transmitting such signals from the central cellular computer site to a central monitoring station whereby the occurrence of a specific condition at the specific location initiates the dialing of an assigned number by the automatic dialer and the transmission of data corresponding to the specific location from the memory through the interface, transceiver and cellular network to the central monitoring station, the cellular network also adapted to receive signals initiated by the central monitoring station and to transmit such signals from the central cellular computer site to the transceiver antenna, whereby such signals are sent through the cellular network, transceiver and interface to the digital dialer and digital communicator.

Claims

1. A system for transmitting data from a specific location such as from a subscriber'"'"'s premises to a central cellular network comprising, in combination, at least one alarm circuit for responding to a specific condition at said specific location for generating an electrical signal in response to said specific condition, a digital communicator including programmable means and an automatic digital dialer, means for connecting said alarm circuit to said digital communicator, a cellular interface, means for connecting said digital communicator to said cellular interface, a cellular transceiver having an antenna, a central cellular network having an antenna in telecommunication with said transceiver antenna and means for connecting said cellular interface with said cellular transceiver whereby data from said programmable means is transmitted over-the-air to said central cellular network in response to said specific condition, and said system further comprising a first alarm monitoring station and a telephone land line connecting said first alarm monitoring station to said central cellular network antenna and a second alarm monitoring station which includes means to connect the second alarm monitoring station to said first alarm monitoring station over-the-air via said cellular network.

2. A system in accordance with claim 1 wherein said programmable means is programmed to provide digital data including at least one telephone number of a location to be called.

3. A system in accordance with claim 2 wherein said digital data from said programmable means includes an account number and a zone identification corresponding to the location of said digital communicator.

4. A system in accordance with claim 3 wherein said programmable means comprises a PROM.

5. A system in accordance with claim 4 wherein said PROM is interchangeable with a second PROM having a different set of data.

6. A system in accordance with claim 4 wherein said PROM is erasable and reprogrammable with new data.

7. A system in accordance with claim 4 wherein said first alarm monitoring station includes a computer in communication with said telephone land line.

8. A system in accordance with claim 7 including a further cellular transceiver and a second cellular interface at said second alarm monitoring station.

9. A system in accordance with claim 7 wherein said first alarm monitoring station includes means for transmitting data from said first alarm monitoring station through said telephone land line said central cellular network, said cellular transceiver and said cellular interface to said PROM for reprogramming said PROM.

10. A system in accordance with claim 1 wherein said specific location is movable.

11. A system in accordance with claim 10 wherein said movable specific location comprises an aircraft.

12. A system in accordance with claim 10 wherein said movable specific location comprises a railroad car.

13. A system in accordance with claim 10 wherein said movable specific location comprises a watercraft.

14. A system in accordance with claim 10 wherein said movable specific location comrises a motor vehicle such as a motor home, mobile home, tractor, tractor/trailer or the like.

15. A system in accordance with claim 14 wherein said alarm circuit comprises a radio frequency receiver and means for linking said radio frequency receiver to said digital communicator.

16. A system in accordance with claim 15 wherein said radio frequency receiver comprises a radio frequency transmitter whereby activation of said radio frequency transmitter at a predetermined distance from said radio frequency receiver will generate said electrical signal and transmit said electrical signal from said radio frequency receiver to said digital communicator.

17. A system in accordance with claim 15 wherein said radio frequency transmitter is an out-of-range type.

18. A system in accordance with claim 1 including at least one closed circuit television camera at said specific location for producing a TV image of said specific location, a video transmitter at said specific location connected to said TV camera and to said digital communicator, a video receiver operatively associated with said first alarm monitoring station, said video transmitter being adapted to respond to said electrical signal for transmitting said TV image to said video receiver.

19. A system in accordance with claim 18 including means associated with said first alarm monitoring station for activating said video transmitter for transmission of said TV image to said video receiver.
