Handheld field maintenance tool with improved locational awareness functionality
First Claim
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 physical position of the handheld field maintenance device relative to a physical position of at least one asset, wherein the controller is further configured to determine a physical position of the handheld field maintenance device by triangulating using wireless process communication with a number of wireless field devices, each having a known, fixed physical position.

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.
