Embodiment 1

[0018] In Figures 1 and 5, the digital level and the optical level indoor verification device of this embodiment are composed of a front-sight inspection and adjustment collimator 1 and a rear-sight inspection and adjustment collimator 2, and the rear-sight inspection and adjustment collimator 2 is connected to the front The structures of the collimator 1 are identical for inspection and adjustment. When verifying the digital level and the optical level, fix the front-sight inspection and adjustment collimator 1 on the front-sight cement pier 8, the rear-sight inspection and adjustment collimator 2 on the rear-sight cement pier 6, and the digital level 3 or optical level to be tested The level is fixed on the two-dimensional micro-tilt platform 4 on the same axis between the front-view inspection collimator 1 and the rear-view inspection collimator 2, and the two-dimensional micro-tilt platform 5 is installed on the cement pier 7 fixed on the instrument under test. On the lift...

Embodiment 2

[0023] In this embodiment, the Zeiss short-distance barcode 1-8-2 is to engrave 41 barcodes on a lens 1-8- In the first column on the left of 1, the Zeiss long-distance barcode 1-8-3 is to engrave the 59 barcodes on the Zeiss barcode scale of the Zeiss series digital level with a distance of 424mm from bottom to top by 120 times and engrave it on a lens 1- 8-1, the second column on the left, Leica long-distance barcode 1-8-4 is to engrave 161 barcodes on a lens with a distance of 921mm from the bottom to the top of the barcode on the barcode of the Leica series digital level by 120 times. The third column on the left of -8-1, the Leica close-range barcode 1-8-5 is to reduce the barcode on the barcode scale of the Leica series digital level from bottom to top with a distance of 544mm by 50 times and engrave it on a lens 1-8-1 on the fourth column from the left. Topcon short-distance barcode 1-8-8 is to engrave 141 barcodes on the barcode scale of Topcon series digital levels w...

Embodiment 3

[0025] In this embodiment, the Zeiss short-distance barcode 1-8-2 is to engrave 41 barcodes on a lens 1-8- In the first column on the left of 1, the Zeiss long-distance barcode 1-8-3 is to engrave the 59 barcodes on the Zeiss barcode ruler of the Zeiss series digital level with a distance of 424mm from bottom to top by 200 times and engrave them on a lens 1- 8-1, the second column on the left, Leica long-distance barcode 1-8-4 is to engrave 161 barcodes on a lens with a distance of 921mm from the bottom to the top of the barcode on the barcode scale of the Leica series digital level by 200 times. The third column on the left of -8-1, the Leica close-range barcode 1-8-5 is to engrave 84 barcodes on a lens with a distance of 544mm from the bottom to the top of the barcode on the barcode of the Leica series digital level by 100 times. 1-8-1 on the fourth column from the left. Topcon short-distance barcode 1-8-8 reduces the barcode on the barcode scale of Topcon series digital le...

Abstract

The present invention relates to an indoor calibrating device for digital balance level and optical balance level. Said device includes forward-locking calibration and regulation collimator and backward-looking calibration and regulation collimator whose structure is identical to that of forward-looking calibration and regulation collimator. Besides, it also includes the components of light-emitting device, object glass, filter, focusing handwheel and focusting tube, etc.

Description

technical field [0001] The invention belongs to the technical field of measuring equipment characterized by optical methods, and in particular relates to measuring the length of an object when it is moving. Background technique [0002] The digital level came out in the early 1990s. At present, there are different series of products produced by German Zeiss, Swiss Leica, Japan Topcon and Sokkia in the international market. It entered the Chinese market in the mid-1990s. It is widely used in the fields of surveying, mapping and precision engineering measurement. However, there is no verification equipment in this area in China. When various types of digital levels are verified by various metrological verification departments, they can only use the bar code scales that match the original instruments for verification outdoors. The bar code scales of various manufacturers have different coding rules. The system cannot be used universally. When testing, place the barcode ruler a...
