System managing resources in mining industry. Supervision system managing staff and equipment identification and localization in mining industry.

Amethyst uses a tele-transmitting radio-network, the main element of which is a leaky feeder applied in the mine corridors, ensuring communication with all receivers/transmitters within the leaky feeder’s range.

Amethyst retrieves data from the acquisition units called Active Tag Readers which collect and remember addresses of tags in their vicinity. Tags are miniature electronic devices located in miner’s lamps or attached to pieces of equipment and machines.


Systems functionality

Handling of communication with tag readers
Exchanges data in the radio tele-transmitting network through communication system units, thus ensures data acquisition.

Database structuring
Structures and backups current and historical data resources about personnel, technical equipment, system operation and administration.

Localization and identification 
Tracks the count and identities of staff members and equipment in defined zones.

Interfacing in web browsers
Ensures visualisation, report generation, data selection and presentation on computer monitors al well as printing.


System configuration

System configuration is performed through a Web browser in such aspects as:

  • Personnel database – setting personnel data availability for edition,
  • Equipment database – setting technical equipment data availability for edition,
  • Gateway setup – insertion and deletion of data considering addresses and parameters of tag readers, which can be matched in pairs to create gateways,
  • Zone setup – defining separate zones by defining  gateways on their borders,
  • User registration – granting user permission to certain ranges of functionality.


Data visualistion

The Amethyst System establishes the present state of the mine (which is updated periodically, by the identification and localization module).

The current state of mine’s resources is presented in the web browser by the following views:

Map – displays mine’s maps in three-dimensional vector graphics using OpenGL technology,

Staff – the history of person’s movement across the mine,

Equipment – the history of changes in equipment position,

Gateways – representing the counter states for equipment and personnel on particular gateways (formed by two tag readers each),

Zones – representing the counters of people and equipment in zones,

Alarms – representing all events considering system operation: failures, warnings, malfunctions as well as the resolutions of such states,

Diagnostics – setting up of appropriate wireless network performance parameters and giving information about data transmission status,

The log – records data and events connected with the user, such as:

  • user identificator,
  • date and time of logging into the system ,
  • the record of succeeded and failed attempts to access the system and its resources,
  • files tables and transactions that have been exposed to the user.
