3. MOTIVATION
 In the mining process a common challenge is to effectively utilize the earth moving
equipment such as dumpers and excavators in real time.
 If these dumpers can be monitored right from their loading point till the ore processing
plant then the cycle time can be greatly reduced. Optimisation of their movement
would make the mining process efficient and improve the throughput of the overall
system.
 In normal situations almost all mines suffer from the problem of having access to
standard networks for communication as deep mining point is roughly 100 meters
below the normal level where ordinarily GSM network is not available.
 The structure of the mines also differ from one another. Hence no standard hardware
and software solution exists which could be used for all mines for their process
monitoring.
 Hence an embedded system is to be developed to keep a track of the vehicular
movement in mines based on which personnel in the control room can send directions
to those vehicles.

4.  Monitoring each vehicle movement through wireless network in the control room.
 Monitoring the weight measured and recorded in the weigh bridge in the control room
through wireless transmission.
 Providing necessary direction to the vehicle for effective management.
Project Specific Requirements :
 To design and deploy an efficient embedded electronic hardware system for installation
in vehicles.
 To develop software system for configuration and operation of the hardware installed in
vehicles.
 To develop software for control room server for logging of above data in the database.
 To develop software for virtual display of the vehicle location over a screen.
 To provide communication for necessary management of the tracked vehicles.

11.  GSM/GPRS TTL -Modem works on frequencies
850 MHz, 900 MHz, 1800 MHz and 1900 MHz.
 The Modem is designed with 3V3/5V TTL
interfacing circuitry, which allows you to
directly interface to 5V microcontrollers(
PIC,Arduino,AVR ect) as well as 3V3
Microcontrollers
( ARM,ARM Cortex XX) .
 The baud rate can be configurable from 9600-
115200 through AT command. Initially
Modem is in Autobaud mode.
 This GSM/GPRS TTL Modem is having internal
TCP/IP stack to enable you to connect with
internet via GPRS. It is suitable for SMS as well
as DATA transfer application .
 Built in SIM Card holder.
 Normal operation temperature: -20 °C to +55
°C
 Input Voltage: 5V-12V DC
 Dimensions: 24*24*3mm
 Control via AT commands ( SIMCOM enhanced
AT Commands)
 Low power consumption: 1.0mA(sleep mode)
