1. A tracking and monitoring system for opencast mines comprising a combination of a plurality of programmable active RFID transceiver devices in communication with a microprocessor based computing and storage device, said plurality of programmable active RFID transceiver devices being programmable to operate as coordinators, routers and end devices and having resident hardware specific embedded software capable of forming a dynamic wireless network among themselves such that a first plurality of said plurality of programmable active RFID transceiver devices are programmed as routers which are strategically placed to form an unified wireless mesh-networking infrastructure, wherein each of the programmed routers is capable of transmitting and receiving signals from one or more other routers, end devices, and one of said plurality of programmable active RFID transceiver devices which is programmed as a coordinator, the coordinator capable of receiving and transmitting signals to said routers and said microprocessor based computing and storage device, wherein said microprocessor based computing and storage device is provided with resident wireless sensor network application software for tracking, monitoring and storing of information received via the coordinator, characterized in that each of the programmable active RFID transceiver devices consist of an external caplamp battery (CB), a first light emitting diode (L1), a voltage regulator (VR), a turnover switch (TS), an internal battery supply (BS), a safety arrangement (SA), an embedded radio (ER), a programming port (PR), a universal asynchronous receiver-transmitter output (UO), an analog to digital converter (Al), a buzzer (BU), a message switch (MS), and a second light emitting diode (L2);

  • wherein the external caplamp battery (CB) is connected to light emitting diode (L1) and voltage regulator (VR);

    the voltage regulator (VR) is connected to the turnover switch (TS);

    the turnover switch (TS) is connected to the internal battery supply (BS) and the safety arrangement (SA);

    the safety arrangement (SA) is connected to the programming port (PR) and the embedded radio (ER); and

    the embedded radio (ER) is separately connected to the programming port (PR), the universal asynchronous receiver-transmitter output (UO), the analog to digital converter input (AI), the buzzer (BU), the message switch (MS), and the second light emitting diode (L2).
