Abstract

A remote device or module sends data to a base station when the change in data from the last transmission exceeds a predetermined threshold. The invention also allows for transmission at a minimal specific time interval. Additionally, the device allows for transmissions based on alarm or alerting conditions.

Claims

1. A method for efficiently transmitting data from a remote location to a base station, comprising the steps of:

obtaining a first data sample A and a second data sample B;

transmitting the second data sample B and a first type alarm message to the base station if it is determined that the second data sample B is above a value X; and

transmitting a second type alarm message and the second data sample B to the base station if it is determined that the second data sample B is above additional values.

2. The method of claim 1, further comprising the step of transmitting the second data sample if a predetermined length of time has elapsed.

3. The method of claim 1, wherein the value X comprises a first alarm limit value.

4. The method of claim 1, further comprising the step of transmitting the first type alarm message if the second data sample is below the value X.

5. The method of claim 1, further comprising the step of resetting a counter following transmission of at least one of the data and alarm messages.

6. The method of claim 1, wherein parameter values used to determine whether a transmit condition exists are entered by a user at the remote location.

7. The method of claim 1, wherein the additional values comprise values (A+Y) and (A+Z).

8. The method of claim 7, wherein the value Y comprises a change in value that causes a transmission.

9. The method of claim 7, wherein the value Z comprises a large change in data that triggers the second type alarm message.

10. The method of claim 1, further comprising the step of transmitting the second type alarm message if the second data sample is below both values (A+Y) and (A+Z).

11. A system for efficiently transmitting data from a remote location to a base station (260), comprising:

an input device (230) that obtains a first data sample A and a second data sample B;

a controller (210) that determines whether the second data sample B is above or below a value X and whether the second data sample B is above or below both values (A+Y) and (A+Z); and

a transmitter (140) that transmits the second data sample B and a first type alarm message to the base station if it is determined that the second data sample B is above or below the value X, and transmits a second type alarm message and the second data sample B to the base station if it is determined that the second data sample B is above or below both values (A+Y) and (A+Z).

12. The system of claim 11, wherein the controller further determines whether a predetermined length of time has elapsed and the transmitter transmits the second data sample if it is determined that the predetermined length of time has elapsed.

13. The system of claim 11, wherein the value X comprises a first alarm limit value.

14. The system of claim 11, wherein the value Y comprises a change in value that causes a transmission.

15. The system of claim 11, wherein the value Z comprises a large change in data that triggers the second type alarm message.

16. The system of claim 11, further including a counter, wherein said counter is reset following transmission of at least one of the data and alarm messages.

17. The system of claim 11, further comprising controls for inputting parameter values used to determine whether a transmit condition exists are entered by a user at the remote location.

18. A method for efficiently transmitting data from a remote location to a base station, comprising the steps of:

obtaining a first data sample A and a second data sample B;

transmitting the second data sample B and a first type alarm message to the base station if it is determined that the second data sample B is below a value X; and

transmitting a second type alarm message and the second data sample B to the base station if it is determined that the second data sample B is below both values (A+Y) and (A+Z).
