Abstract
Изобретение относитс к геодезическому приборостроению и может быть использовано при контроле пр молинейности и в наблюдени х за деформаци ми и смещени ми сооружений. Цель изобретени - расширение области использовани - достигаетс за счет устранени вращающихс элементов в приемном канале. Измерение перемещени относительно плоскости сканировани светового луча достигаетс за счет измерени положени пересечени лучом света диагонального элемента Z - образной системы фотоприемников 1-3. С помощью триггеров 9,10 вырабатываютс два импульса, длительность первого пропорциональна положению луча относительно фотоприемника 1, а длительность второго определ етс рассто нием между блоком сканировани луча и фотоприемниками. Длительности импульсов преобразуютс в цифровой код с помощью ключей 11 и 12 и генератора 13 импульсов и регистрируетс индикаторами 16 и 17. 3 ил.The invention relates to geodetic instrumentation and can be used in the control of straightness and in monitoring deformations and displacements of structures. The purpose of the invention, the extension of the field of use, is achieved by eliminating the rotating elements in the receiving channel. Measurement of movement relative to the scanning plane of the light beam is achieved by measuring the position of the intersection of the diagonal element of the Z-shaped system of photodetectors 1-3 by the beam of light. With the help of flip-flops 9, 10, two pulses are generated, the duration of the first is proportional to the position of the beam relative to the photodetector 1, and the duration of the second is determined by the distance between the beam scanning unit and the photo-detectors. Pulse durations are converted into a digital code using keys 11 and 12 and pulse generator 13 and recorded with indicators 16 and 17. 3 sludge.
