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 />
