Remote asset tracking system in UCIL's Narwapahar Mine in India

1. REMOTE ASSET TRACKING SYSTEM 500 feet below ground In UCIL’s Narwa Mine - An R & D Pilot Project Commissioned on 31 st March 2012 at Narwapahar Uranium Mines Uranium Corporation of India Limited October 2012

2. ASSET TRACKING IN UNDERGROUND MINE - WHY Fast track management of emergency situations by voice communication using IP phones. Faster management of breakdowns to minimize downtime of various mine equipment. Better monitoring of mine truck trips. Generation of real time data for industrial engineering studies for better planning.

3. ASSET TRACKING IN UNDERGROUND MINE - WHY Accessing of men and equipment in all locations of the mine by standard hardwired telephones is not possible Fast track management of emergency situations by voice communication using IP phones

4. CONTROL ROOM

5. Introduction This is an R & D project of UCIL in collaboration with M/S TCS. The system has been installed at the 4 th level (140 m below surface). It has three components, viz. Tracking of Vehicles & Key Personnel. Voice Communication between Key Personnel. Production Monitoring by Trip Counting.

6. System Capability The system uses a Wi-Fi based tracking system for real-time and historical tracking of Underground Trackless Equipment. Key Personnel. Wireless voice communication between key personnel in Underground using IP Phones.

7. Wi-Fi Access Point

8. System Capability The system uses RFID based tracking system for Counting of number of trips of ore dumped at the Grizzly by different Mine Trucks. Time Stamping of Dumping of Ore by Mine Trucks.

10. System Components A Control Room in underground. A Wi-Fi network in underground. An RFID network underground. The system uses OFC cables for long distance data transmission.

11. Underground Control Room It has the following installations Server for storage and processing of time stamped data. A graphic user interface showing Location of mine equipment Location of IP Phones (used by Key personnel) It is connected through OFC cables with Wi-Fi Access Points. RFID Readers.

12. Wi-Fi Access Point

13. Underground Wi-Fi Network It consisting of ‘Wi-Fi Access Points’ at various locations consisting of LIU (Light Interface Unit) Media Converter Wi-Fi Antenna near Access Points (Range = 75 m) Wi-Fi tags mounted on mine equipment IP Phones for voice communication

23. System Components A Wi-Fi network Wi-Fi would be primarily used for tracking of assets, voice communication between key miners and the control room on zoned basis. Access Points: A wireless access point (WAP) is a device that allows wireless devices to connect to a wired network using Wi-Fi WCS: Wireless Control System (WCS) includes tools for wireless LAN planning and design, location tracking, and wireless LAN systems configuration, monitoring, and management. MSE: Mobility Services Engine (MSE) is an appliance-based solution that supports a suite of software services to provide centralized and scalable service delivery. API: An application programming interface (API) is a specification intended to be used as an interface by software components to communicate with each other. Application Data Storage: SQL server 2008 is used as database in this solution.

24. System Components An RFID network Individual MT trip count data are gathered by RFID system. RFID Reader: RFID readers use RF waves for communication and therefore must have one or more antennas. The antenna may be externally connected or in the same housing or enclosure as the RFID reader electronics. RFID Tag: The tag transmits information to the reader via antenna, and the reader converts the incoming radio waves into a form that can be read by a computer system. RFID middleware: RFID Middleware communicates with the device; filters redundant data in real time, logs the filtered data along with a time-stamp to a database .The logged data is utilized by the application to create reports of trip count for individual MTs.

25. Application Development Technology The following table describes all the software details used to develop the Remote Asset Tracking application.
