Abstract
Sensor data from a sensor that is associated with a mobile device is obtained with respect to an asset of an indoor facility. Using the sensor data, location coordinates of the mobile device within the indoor facility, the coordinates being in a global frame of reference. Identification information associated with the asset is also received. The coordinates from the global frame of reference are converted to a frame of reference of the indoor facility. The converted coordinates and the identification information are associated with a work order associated with the asset. An asset map is updated with the converted coordinates of the asset and represents a digital twin of the indoor facility.

A system comprising:
- a database;
- and
- a mobile device comprising:
- a processing resource communicatively coupled to the database via an electronic network;
- a magnetic sensor coupled to the processing resource;
- and
- a machine readable medium coupled to the processing resource and storing instructions that, where executed by the processing resource and when the mobile device has been brought to within three meters or less of an asset of an indoor facility because of an identified operational problem at the asset, cause the processing resource to:
- responsive to the mobile device being within three meters or less of the asset of the indoor facility and responsive to a creation of an electronic work order, selectively transmit an electronic control signal to the sensor to actuate the magnetic sensor and obtain sensor data from the magnetic sensor, the sensor data comprising magnetic field measurements from the magnetic sensor, the work order comprising an electronic data structure describing the asset and the identified operational problem associated with the asset;
- determine, by correlating the sensor data to a stored magnetic field map of the indoor facility, location coordinates with sub-meter accuracy of the mobile device within the indoor facility, the location coordinates being in a global frame of reference;
- receive identification information associated with the asset;
- convert the coordinates from the global frame of reference to converted coordinates in a frame of reference of the indoor facility;
- and
- associate the converted coordinates and the associated identification information with the work order associated with the asset, the work order stored in the database, and wherein an asset map in the database for the indoor facility is updated with the converted coordinates of the asset, the asset map representing a digital twin of the indoor facility.
