Use of low energy bluetooth beacons to locate field equipment and personnel

A management system for a plant facility, comprising:

• a server device;
• a mobile terminal that communicates with the server device;
• and
• a plurality of beacon transmitters, wherein each of the beacon transmitters is attached to or embedded into a field device that measures process data or controls one or more controlled objects in the plant facility and broadcasts a beacon signal comprising an identifier that identifies the field device, wherein
• the mobile terminal comprises:
• a mobile terminal display;
• a beacon receiver that receives the beacon signals;
• and
• a mobile terminal controller that calculates a distance from the mobile terminal to each of the beacon transmitters based on strength of the beacon signal received from each of the beacon transmitters,
• the server device comprises:
• a server device display;
• a server device storage that stores the process data collected from each of the field devices and a name and a description of each of the field devices corresponding to each of the identifiers;
• and
• a server device controller that
• receives wireless signals comprising the identifiers from the mobile terminal, and
• identifies the process data, the name, and the description corresponding to each of the identifiers received with the wireless signals,
• the mobile terminal controller
• transmits the wireless signals to the server device with the identifiers received with the beacon signals, and
• at least one of the server device display and the mobile terminal display displays the calculated distances and the process data, the name, and the description of the field device identified by the server device controller.
