Abstract

A handheld field maintenance tool is provided. The tool includes, among other things, a wireless process communication protocol module configured to communicate in accordance with a wireless process communication protocol. The tool also includes a display and an input device. A controller is coupled to the wireless process communication protocol module, the display, and the input device. The controller is configured to generate a map on the display indicating a position of the handheld field maintenance device relative to at least one asset, such as a field device. The controller is further configured to determine a position of the handheld field maintenance device by triangulating using wireless process communication with a number of known, fixed-position wireless field devices.

Claims

1. A handheld field maintenance tool comprising:

a wireless process communication protocol module configured to communicate in accordance with a wireless process communication protocol;

a display;

an input device; and

a controller coupled to the wireless process communication protocol module, the display, and the input device, the controller being configured to generate a map on the display indicating a position of the handheld field maintenance device relative to at least one asset, wherein the controller is further configured to determine a position of the handheld field maintenance device by triangulating using wireless process communication with a number of known, fixed-position wireless field devices.

2. The handheld field maintenance tool of claim 1, wherein the at least one asset includes a field device.

3. The handheld field maintenance tool of claim 1, and further comprising a GPS module coupled to the controller, the GPS module configured to receive satellite GPS signals to determine a position of the handheld field maintenance tool.

4. The handheld field maintenance tool of claim 1, wherein the controller provides an indication of the asset in a center of the map.

5. The handheld field maintenance tool of claim 4, wherein the indication of the asset is an icon.

6. The handheld field maintenance tool of claim 5, wherein a parameter of the icon varies with a parameter known relative to the asset.

7. The handheld field maintenance tool of claim 6, wherein the parameter of the icon is transparency, and the parameter known relative to the asset is height relative to ground level.

8. The handheld field maintenance tool of claim 1, wherein the handheld field maintenance tool is intrinsically-safe.

9. A method of locating a field device using a handheld field maintenance tool, the method comprising:
