Abstract

An electrical power generator for outputting on-site electrical power comprises an engine; an alternator operatively coupled to the engine; a controller, operatively coupled to the engine and alternator for controlling at least one operational parameter relating to the engine or alternator, and a modem operatively coupled to the controller for receiving data from a remote source, the received data then being processed by the controller to control the operation parameter.

Claims

1. An electrical power generator for outputting onsite electrical power to a cellular base station, the power generator comprising:

an engine;

an alternator operatively coupled to the engine;

a controller, operatively coupled to the engine and alternator, for controlling at least one operational parameter relating to the engine or alternator, and

a modem, operatively coupled to the controller, for receiving data from a remote source, the received data being processed by the controller to control the operational parameter.

2. The power generator of claim 1 wherein the power generator includes a switch for disconnecting electrical power form the power generator to the cellular base station in favor of another source of power to the cellular base station.

3. The power generator of claim 1 wherein the modem for communicating data comprises a GSM modem for wirelessly transmitting and receiving the data.

4. The power generator of claim 1 wherein the engine is a diesel powered engine.

5. The power generator of claim 4 wherein the engine includes an oil sump which contains at least 11 liters of oil.

6. The power generator of claim 1 wherein controller is capable of running a load test for optimizing operation of the engine, data reflecting the load test being remotely transmitted by the modem.

7. The power generator of claim 1 further comprising a battery for providing power to start the engine and an auxiliary battery for providing auxiliary electrical power to the controller and the modem.

27. The power generator of claim 1 further comprising a load bank which is switchably connected to the alternator.

8. A system comprising:

a cellular base station for communicating signals with one or more cellular telephones;

an electical power generator located on the site of and connected to the cellular base station, the power generator including an engine, an alternator coupled to the engine, a controller for controlling at least one operational parameter of the alternator or engine, and a modem for remotely communicating data relating to the operational parameter of the alternator or engine; and

a processing system remotely located from the power generator and the cellular base station, the processing system communicating data with the modem.

9. The system of claim 8 wherein the modem is a GSM modem for wirelessly transmitting and receiving data from the processing system, the processing system comprising a a computer system including another modem.

10. The system of claim 8 wherein the modem is a GSM modem for wirelessly transmitting and receiving data from the processing system, the processing system comprising a cellular telephone.

11. The system of claim 8 wherein the engine is a diesel powered engine.

12. The system of claim 11 wherein the engine includes an oil sump which contains at least 11 liters of oil.

13. The system of claim 8 wherein the controller is capable of running a load test for optimizing operation of the engine, data reflecting the load test being transmitted from the modem to the processing system.

14. The system of claim 8 wherein the power generator further comprises a battery for providing power to start to the engine and an auxiliary battery for providing auxiliary electrical power to the controller and the modem.

15. The system of claim 9 further comprising another cellular base station and another on-site electical power generator located on the site of and connected to the another cellular base station, and another modem for remotely communicating data relating to the operational parameter of the another power generator to the processing system, the processing system being remotely located from the another base station and the another on-site electrical power generator.

28. The system of claim 8 wherein the power generator includes a load bank which is switchably connected to the alternator.

16. A method of remotely controlling a power generator which provides on-site electrical power to a cellular base station, the method comprising:

receiving in a modem of the power generator data from a processing system that is remotely located from the power generator, the received data reflecting a command for controlling at least one operational parameter of an alternator or engine of the power generator; and

processing the received data and controlling the operational parameter of the alternator or engine of the power generator in accordance with the received data.

17. The method of claim 16 wherein the modem is a GSM modem for wirelessly receiving the data.

18. The method of claim 17 further comprising switchably connecting primary and auxiliary batteries to the GSM modem.
