GREIČIO MATUOKLIAI
GREIČIO MATUOKLIAI
GREIČIO MATUOKLIAI
• 1. Kaip veikia greičio matuokliai?
Greičio matuokliai veikia "šūvio" principu, greičio matavimo metu matuoklis "šauna",
radarų detektorius šūvį aptinka ir apie jį praneša garsiniu signalu. Greičio matuoklių tipai:
1) Radarai - matuodami greitį skleidžia radijo bangas. Bangos nėra koncentruotos,
pasklinda didelėje teritorijos dalyje, todėl yra lengvai aptinkamos net nesant tiesioginiam
matomumui.
2) Lidarai (arba lazeriai) - greičiui matuoti naudoja IR spindulį (panašiai kaip TV valdymo
pultas). Ne taip kaip radijo bangos, lazerio spindulys yra siauras, koncentruotas tik į tą
vietą kur nusitaikoma, todėl aptikti lazerį įmanoma tik tiesioginio matomumo zonoje.
Matuojant greitį siunčiamas IR spindulys, kuris atsimušęs nuo automobilio paviršiaus turi
sugrįžti atgal, greičio matuoklis tokiu būdu apskaičiuoja automobilio greitį - visa tai įvyksta
akimirksniu.
FOTORADARAS
• Automatinė greičio matavimo sistema, fotografuojanti greitį viršijančias transporto
priemones. Fotoradarai gali būti įrengti stacionariai, bei automobilyje, todėl greitį
viršijančius gali netikėtai užklupti bet kurioje vietoje.
DAŽNIAI
• Radijo dažniais veikiantis greičio matuokliai
Standartiniai dažniai:
X banga: 10.525 ± 25 MHz (10.500 - 10.550 GHz)
K banga: 24.150 ± 100 MHz (24.050 - 24.250 GHz)
Ka banga: 34.700 ± 1300 MHz (33.400 - 36.000 GHz)
Ku banga: 13.450 ± 50 MHz (13.400 - 13.500 GHz)
DAŽNIŲ SKIRTUMAI
• Tačiau greičio matuokliai naudojami Europoje šiek tiek skiriasi nuo naudojamų JAV:
JAV:
X: 10.525 ± 25 MHz
K: 24.150 ± 100 MHz
Ka: 33.800 ± 100 MHz; 34.700 ± 100 MHz; 35.500 ± 100 MHz
Europa:
X: 10.525 ± 25 MHz
K: 24.150 ± 100 MHz
24.125 ± 25 MHz
24.100 ± 25 MHz
Ka1: 34.000 ± 100 MHz
Ka2: 34.360 ± 100 MHz
Ka3: 34.700 ± 100 MHz
Ka4: 35.500 ± 100 MHz
Ku: 13.450 ± 50 MHz
Lietuva:
K: 24.150 ± 100 MHz
24.125 ± 25 MHz
24.100 ± 25 MHz
APIBENDRINIMAS
• Kelyje vis didėjant nesaugiam vairavimui ir pažeidimų skaičiui, Lietuvos pareigūnai kovoja
ne tik patys tačiau ir pasitelkę greičio matuoklius.
• Saugus vairavimas nesibaigia pristabdžius prieš greičio matuoklį tad būkime kultūringi ir
laikykimės saugaus greičio.
