Abstract

Изобретението се отнася до метод и система за безконтактно измерване на изминат път, които ще намерят приложение при строителство и ремонт на пътища и релсов път. Методът включва следните операции: излъчване на лъчи от лазерно-оптични безконтактни сензори (1), поставени върху подвижна платформа (8) към измервания обект; - на базата на доплеровия ефект, отразеният от обекта сигнал, се обработва в аналогови електрически импулси, пропорционални на изминатия път; налоговите електрически импулси от сензорите (1) постъпват в аналого-цифров преобразувател (3), преобразуват се в цифров сигнал, който се подава към изчислителен блок на интерфейсна система (5), където постъпват и сигнали от инерциална изчислителна система (2) и синхронизиращи сигнали от синхронизиращи устройства (4); постъпилите сигнали се обработват от изчислителния блок на интерфейсната система (5) и сигналът от изчислителния блок на интерфейсната система (5) се подава към централен изчислителен блок (6), който изчислява местоположението и изминатия път от предварително определена начална точка и подава окончателните данни към краен ползвател.
