PORTABLE FIELD TOLL FOR MAINTENANCE WITH IMPROVED FUNCTION OF BASIC INFORMATION AWARENESS Russian patent published in 2015 - IPC G05B19/418 H04W24/02 G01D21/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to portable field tools for maintenance. A tool (52, 102) comprises, without limitation, a module (121) of protocol of wireless communication of a technological process configured with the possibility to maintain communication in accordance with the protocol of wireless communication of technological process. The tool (52, 102) also includes a display (120) and an input device (122). A controller (130) is connected with a module of protocol of wireless communication of technological process, the display (120) and the input device (122). The controller (130) is configured with the possibility of processing a map on a display (120), showing the position of the portable field device (52, 102) relative to at least one facility, such as a field device (22, 23, 104). The controller (130) is additionally configured as capable to determine position of the portable field device (52, 102) for maintenance by means of triangulation using wireless communication of technological process with a row of available field devices (104) with fixed position.

EFFECT: more accurate determination of location of a field device due to mutual use of GPS and triangulation.
