Problems solved by technology
The measurement distance of the total station and electronic level can meet the requirements, but the measurement accuracy is about 0.5mm
Most of them use the method of visual inspection, and the measurement accuracy is restricted by man-made, light, etc., which cannot meet the precision measurement requirements of modern industrial sites.

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] Taking two Tianjin AUTOMAT ULTRA 5000 dual-axis photoelectric autocollimators as an example, the measurement range of Tianjin AUTOMAT ULTRA 5000 dual-axis photoelectric autocollimator is 30 meters, and the dual-axis precision can reach 0.1 micron.
[0024] Utilize Tianjin AUTOMAT ULTRA 5000 type biaxial photoelectric autocollimator, the present invention comprises the following steps:
[0025] 1) if figure 1 As shown, two dual-axis photoelectric autocollimators 1 are respectively installed on the adjustable bridge plate 2 as the measurement calibrator 3 and the calibrator 4 respectively.
[0026] 2) if figure 2 As shown, at about 0.5 meters in front of the head end A of the platform 5 to be measured, a base point reflector 6 is set as the position of the permanent reflection base point. The measurement calibrator 3 is placed on the platform 5 to be measur...

The invention discloses a measuring method for a long-distance plane or a long-distance guide rail. Firstly, two double-shaft photoelectric auto-collimators are manufactured into a measurement calibration instrument and a calibrator, a base point reflecting mirror and the measurement calibration instrument are arranged on a platform to be measured, a horizontal locating base axis and a longitudinal locating base axis are selected, and the base point reflecting mirror or the measurement calibration instrument is adjusted to enable the cross cursor on the interface of the measurement calibration instrument to carry out zero calibration on an X axis and a Y axis. A detection reflecting mirror is moved between the head end of the platform to be measured and the measurement calibration instrument to carry out measurement on a workpiece. The calibrator is mounted between the head end of the platform to be measured and the measurement calibration instrument, the calibrator is adjusted to enable the cross cursor on the interface of the measurement calibration instrument to carry out the zero calibration on the X axis and the Y axis, then the measurement calibration instrument is moved backwards and is adjusted to enable the cross cursor on the interface of the measurement calibration instrument to carry out zero calibration on the X axis and the Y axis, the calibrator is shifted out, and the detection reflecting mirror is moved in the area to carry out construction measurement on the workpiece. The measuring range of the method reaches more hundreds of meters, measuring precision can be guaranteed, and measuring accuracy is smaller than or equal to 10 micrometers.
Description
technical field [0001] The invention relates to a photoelectric measurement method, in particular to a long-distance plane or guide rail measurement method. Background technique [0002] At present, the straightness and flatness measuring instruments with high measurement accuracy, such as MOLLER in Germany, API in the United States, and TAXLOR HOBSON in the United Kingdom, have a measurement distance of only a few meters to tens of meters. However, the measurement distance of the total station and the electronic level can meet the requirements, but the measurement accuracy is about 0.5mm. Most of them use the method of visual inspection, whose measurement accuracy is restricted by man-made, light, etc., and cannot meet the accuracy measurement requirements of modern industrial sites. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a long-distance plane or guide rail measurement method with larg...
