Problems solved by technology

[0011] Guide rail fixed verification system, because the reflective prism is placed on the fixed point of each displacement distance of the guide rail, the verification system only needs one person to operate, but due to the lateral reset of the reflective prism on the moving distance measurement point, manual electronic control is required. Reset, still Affected by heavy workload and low work efficiency

Embodiment Construction

[0036] Such as figure 1 , figure 2 , image 3 , Figure 10 , Figure 11 The automatic verification system for the periodic error of the photoelectric range finder includes a guide rail 2, a distance measuring reflective prism 1, and a detection pier 3 for placing the photoelectric range finder. The distance measuring reflective prism 1 is placed on the guide rail 2 according to the interval required for periodic error detection. Above; the photoelectric distance meter periodic error automatic verification system also includes a control box and a computer, and the distance measuring reflective prism 1 is an automatic prism; the computer is connected to the control box, and the control box controls the automatic prism and the photoelectric distance meter to be tested. The guide rail 2 is a large-span reinforced concrete T-beam, which is characterized by a simple structure, better resistance to deformation and deflection. The placement of the electric prism group is based on...

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...
