Example Embodiment

[0036] Such as figure 1 , figure 2 , image 3 , Picture 10 , Picture 11 The illustrated photoelectric rangefinder periodic error automatic verification system includes a guide rail 2, a distance measuring reflector 1 and a detection pier 3 for placing the photoelectric distance meter. The distance measuring reflector 1 is placed on the guide rail 2 at intervals required for periodic error detection. Top; The automatic verification system for periodic error of the photoelectric rangefinder also includes a control box and a computer. The distance measuring reflector 1 is an automatic prism; the computer is connected to the control box, and the control box controls the automatic prism and the photoelectric rangefinder to be measured. The guide rail 2 is a large-span reinforced concrete T-beam, which is characterized by a simple structure, good resistance to deformation and deflection. The arrangement of the electric prism group is based on the actual precision measurement freque...

Abstract

The invention discloses a system for automatically detecting the periodic error of a photoelectric distance measuring instrument. The system comprises a guide rail, distance measuring reflecting prisms, and a detection pier for accommodating the photoelectric distance measuring instrument, wherein the distance measuring reflecting prisms are arranged on the guide rail at intervals according to the periodic error detection requirement. The system for automatically detecting the periodic error of the photoelectric distance measuring instrument is characterized by also comprising a control box and a computer, wherein the distance measuring reflecting prisms are automatic prisms; the computer is connected with the control box; and the control box controls the automatic prisms and the photoelectric distance measuring instrument to be detected. The system for automatically detecting the periodic error of the photoelectric distance measuring instrument has low cost, high efficiency and high automation degree, and can easily and accurately detect the periodic error of the photoelectric distance measuring instrument.

Description

technical field [0001] The invention relates to a photoelectric distance measuring instrument, in particular to an automatic verification system for the periodic error of the photoelectric distance measuring instrument. Background technique [0002] According to the current national standard of the People's Republic of China GB / T 14267-2009 "Photoelectric Range Finder", the periodic error measurement of the photoelectric range finder is verified by the platform method. The platform method verification mainly adopts the following methods. The verification platform structure adopts the guide rail type: there are "I-shaped steel guide rail", "double-axis garden guide rail", "marble flat guide rail" and other types; the detection device system adopts: guide rail sliding system and Guide rail fixed system; guide rail sliding system has manual control system and automatic control system; guide rail fixed currently only has manual control system. [0003] The guide rail sliding me...
