Abstract

Data is transmitted from a portable handheld device (“HHD”) at a remote site to a control facility using wireless data transmission. In response, the control facility creates and sends a measurement instruction or command to the HHD. The command sent to the HHD can be based at least in part on the data previously received from the HHD.

12. A method of monitoring the condition of a machine, the method comprising:

selecting a first measurement instruction at a central computer;

wirelessly receiving the first measurement instruction;

connecting a transducer to the machine for collecting data, wherein the data relates to the first measurement instruction;

transmitting the data to the central computer;

processing the transmitted data at the central computer;

selecting a second measurement instruction at the central computer; and

wirelessly receiving the second measurement instruction from the central computer.

13. The method of claim 12, wherein the first measurement instruction and the second measurement instruction are received over the same wireless link.

14. The method of claim 12, wherein determining the second measurement instruction comprises comparing a previous measurement for the machine to the processed data.

15. The method of claim 12, wherein determining the second measurement comprises comparing a predetermined threshold value to the processed data.

16. The method of claim 12, wherein the first measurement instruction includes a type of and location for collecting data from the machine.

17. A portable computer for an operator to receive and display instructions for measuring operational characteristics of a machine, the portable computer comprising:

means for wirelessly receiving an instruction from a central computer to measure an operational characteristic of the machine;

software configured to interpret the received instruction;

a processor configured to execute the software;

a graphical user interface configured to display information related to the instruction and to the operational characteristic of the machine;

a connector configured to receive data related to the operational characteristic; and

means for transmitting the data to the central computer.

18. The portable computer of claim 17, wherein the means for wirelessly receiving the instruction from the central computer is further configured to receive a second instruction from the computer, wherein the second instruction is based at least in part on the data transmitted by the means for transmitting.

19. The portable computer of claim 18, wherein the display information identifies a location on the machine for locating the measurement device.

20. The portable computer of claim 18, wherein the display information identifies a type of measurement.

21. The portable computer of claim 20, wherein the type of measurement is a temperature measurement.

22. The portable computer of claim 20, wherein the type of measurement is a vibration measurement.

23. A central computer for determining a plurality of instructions for an operator to perform a plurality of measurements to determine the operational characteristics of a type of machine, the central computer comprising:

software configured to determine a series of instructions for the operator to perform the plurality of measurements;

a processor configured to execute the software;

a transmitter configured to transmit a first instruction and a second instruction from the series of instructions to a portable computer over a wireless link;

a receiver configured to receive data related to the transmitted first instruction from the portable computer over the wireless link; and

means for selecting the second instruction of the series of instructions based at least in part on the data related to the first instruction.

24. The central computer of claim 23, further comprising a graphical user interface configured to display data related to the transmitted first instruction.

25. The central computer of claim 23, wherein the means for determining the second instruction comprises software.
