 REAL-TIME MONITORING OF RAILWAY TRAFFIC USING
         FIBER BRAGG GRATING SENSORS
In this work, we present field tests concerning the application of fiber
Bragg grating (FBG) sensors for the monitoring of railway traffic. The
test campaigns are performed on the Spanish high-speed line Madrid-
Barcelona, with different types of trains (S-102 TALGO-
BOMBARDIER, S-103 SIEMENS-VELARO, and S-120 CAF).
We located the FBG sensors in the rail track at 70 km from Madrid in
the country side, where the trains primarily are tested during
commercial operation with maximum speeds between 250-300 km/h.
The FBG sensor interrogation system used allows the simultaneous
monitoring of four FBG sensors at 8000 samples/s.
The different position of the FBG sensors in relation with the ra il can
be used for different purposes such as train identification, axle
counting, speed and acceleration detection, wheel imperfections
monitoring, and dynamic load calculation.

ABOUT EMBEDDED SYSTEMS
An embedded system is a computer system designed for specific control functions within a
larger system, often with real-time computing constraints. It is embedded as part of a complete
device often including hardware and mechanical parts. By contrast, a general -purpose computer,
such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-
user needs. Embedded systems control many devices in common use today
Embedded systems contain processing cores that are typically either microcontrollers or digital
signal processors. The key characteristic, however, is being dedicated to handle a particular
task. Since the embedded system is dedicated to specific tasks, design engineers can optimize
it to reduce the size and cost of the product and increase the reliability and performance.
Embedded systems are designed to do some specific task, rather than be a general-purpose
computer for multiple tasks. Some also have real -time performance constraints that must be
met, for reasons such as safety and usability
Embedded systems are not always standalone devices. Many embedded systems consist of
small, computerized parts within a larger device that serves a more general purpose. The
program instructions written for embedded systems are referred to as firmware, and are stored
in read-only memory or Flash memory chips. They run with limited computer ha rdware
resources: little memory, small or non-existent keyboard or screen.




                                      PERIPHERALS
      Embedded Systems talk with the outside world via peripherals, such as:
   Serial Communication Interfaces (SCI): RS-232, RS-422, RS-485 etc.
   Synchronous Serial Communication Interface: I2C, SPI, SSC and ESSI (Enhanced
   Synchronous Serial Interface)
   Universal Serial Bus (USB)
   Multi Media Cards (SD Cards, Compact Flash etc.)
   Networks: Ethernet, LonWorks, etc.
   Fieldbuses: CAN-Bus, LIN-Bus, PROFIBUS, etc.
   Timers: PLL(s), Capture/Compare and Time Processing Units
   Discrete IO: aka General Purpose Input/Output (GPIO)
   Analog to Digital/Digital to Analog (ADC/DAC)
   Debugging: JTAG, ISP, ICSP, BDM Port, BITP, and DP9 ports.

MICROCONTROLLERS
A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a single
integrated circuit containing a processor core, memory, and programmable input/output
peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on
chip, as well as a typically small amount of RAM.
Microcontrollers are designed for embedded applications, in contrast to the microprocessors
used in personal computers or other general purpose applications.
Microcontrollers are used in automatically controlled products and devices, such as automobile
engine control systems, implantable medical devices, remote controls, office machines,
appliances, power tools, toys and other embedded systems. By reducing the size and cost
compared to a design that uses a separate microprocessor, memory, a nd input/output devices,
microcontrollers make it economical to digitally control even more devices and processes




ATMEL 89C51 MICROCONTROLLERS
The Atmel AT89 series is an Intel-8051-compatible family of 8 bit microcontrollers (µCs)
manufactured by the Atmel Corporation. Based on the Intel 8051 core, the AT89 series remains
very popular as general purpose microcontrollers, due to their industry standard instruction set,
and low unit cost. This allows a great amount of legacy code to be reused without modif ication in
new applications
The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4Kbytes of
Flash programmable and erasable read only memory (PEROM). The device is manufactured
using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-
standard MCS-51 instruction set and pin out.
The on-chip Flash allows the program memory to be reprogrammed in -system or by a
conventional nonvolatile memory programmer. By combining a versatile 8 -bit CPU with Flash on
a monolithic chip, the Atmel AT89C51 is a powerful microcomputer, which provides a highly -
flexible and cost-effective applications solution to many embedded control
