The AVR bootloader feature may be used to change any<br />

module microcontroller program memory <strong>and</strong>/or the FPGA<br />

configuration memory content, which facilitates firmware upgrades.<br />

All radio parameters can be set up us<strong>in</strong>g a dedicated<br />

software connected to the DMI module service RS232 port.<br />

VII. APPLICATIONS AND EXPERIENCES<br />

Based on the referred solution, some <strong>in</strong>terest<strong>in</strong>g applications<br />

of the radio set have been implemented. Their <strong>number</strong><br />

<strong>in</strong>cludes:<br />

• tra<strong>in</strong> localization <strong>and</strong> locomotive parameters monitor<strong>in</strong>g<br />

system,<br />

• DSR dispatcher system – remotely controlled VHF base<br />

station sets for railway ma<strong>in</strong> tracks,<br />

• G.sHDSL modem for the radio remote controll,<br />

• GIS RSSI measurement system for railway tracks.<br />

Presented below is a selection of screens <strong>and</strong> diagrams of the<br />

aplications mentioned.<br />

Fig. 5 presents “Qguar Qpilot” fleet management system<br />

architecture from Quantum Software S.A. The “Koliber” radio<br />

set sends localization data from GPS via the GPRS l<strong>in</strong>k to the<br />

company’s APN GSM <strong>in</strong>frastracture. Fig. 6 presents a sample<br />

GUI w<strong>in</strong>dow from the application.<br />

Fig. 7 presents real time visualization of the locomotive<br />

parameters from the “Koliber” switch module, connected to<br />

the CL400 module of the locomotive monitor<strong>in</strong>g unit (manufactured<br />

by ZEPWN).<br />

Fig. 9 presents an architecture of the DSR dispatcher radio<br />

system,whichconsistsofseveralradiobasestationscontrolled<br />

by dispatchers from the Local Control Center. Each base<br />

station <strong>in</strong>cludes up to 4 radios, along with a service DMI<br />

module <strong>and</strong> a control unit. Base stations are connected with<br />

Local Control Center by SDH based E1 l<strong>in</strong>ks, form<strong>in</strong>g a star<br />

structure.<br />

Fig. 10 presents example results of the radio signal strength<br />

measurement system done with the “Koliber” set on one of<br />

the ma<strong>in</strong> Polish rail tracks.<br />

VIII. CONCLUSION<br />

A few years of us<strong>in</strong>g the “Koliber” system <strong>in</strong> railway<br />

radio networks allow the conclusion that the design based<br />

on a simple 8-bit microcontroller, equipped with few external<br />

devices for dedicated functions, is fully justified. The design<br />

was verified by approved<strong>in</strong>dustrial bodies, positively tested <strong>in</strong><br />

the real consumer world, <strong>and</strong> opened many new application<br />

fields.<br />
