Description
Technical field:
the invention belongs to the technical field of digital level verification and calibration, and particularly relates to a rotary code ruler for digital level electronic i angle and line-of-sight error verification.
The background technology is as follows:
the digital level, also called electronic level, is a high-precision height measuring equipment, and is composed of three main units of main machine, bar code ruler and data processing software. The measuring principle is that a horizontal alignment line can be provided in the ocular, and the bar code measuring elevation on the bar code ruler at the corresponding position is read. The i angle error of the electronic level is the sighting axis error of the electronic level, in the measuring process of the electronic level, when the leveling tube axis of the level is spatially parallel to the sighting axis of the telescope, the projection on the vertical plane is parallel, if the two axes are not parallel, the projection on the vertical plane is also not parallel, the error is caused when the leveling is carried out, and the i angle error is a particularly important calibration value when the leveling is carried out.
At present, when the electronic angle i of the digital level is detected, four outdoor methods are mainly adopted for correction:
(1) The Fust-Nel method: as shown in fig. 1, two scales (A, B) are set up at a distance of 45m, the distance is divided into three equal parts, 2 instrument stations (1, 2) are set up on the connecting line of the two scales, the distance is about 15m, then the two scales are measured from the measuring stations, and the calculation formula of the i angle is as follows:
in the middle of、/>、/>、/>The readings of the two scales (A, B) observed by the digital level at positions 1 and 2 respectively, S is the distance of each equivalent, ρ is a constant which is usually used for calculation in measurement, and the value of the constant is about 206265, namely a second value corresponding to one radian, namely that one radian is about 206265 seconds.
(2) The Napolo method: as shown in fig. 2, a distance of 45m is measured, namely, the distance is divided into three equal parts, instruments are arranged on the two sides (1, 2), two scales (A, B) are arranged at one third of the distance from the two ends, the two scales are measured from a measuring station, and the calculation formula of the angle i is as follows:
in the middle of、/>、/>、/>Respectively digital levelThe readings of the two scales (A, B) observed by the instrument at 1, 2, S being the distance per aliquot.
(3) The library card Ma Kefa: as shown in fig. 3, two scales (A, B) are set up at a distance of about 20m, and first readings are taken on the two scales from a measuring station (1) located in the middle of the line connecting the two scales. Then reading on two scales from a measuring station (2) 20m away from the extension of the two scales, wherein the calculation formula of the angle i is as follows:
in the middle of、/>、/>、/>The readings of the two scales (A, B) observed by the digital level at 1 and 2 respectively, and S is the distance between the two scales (A, B).
(4) The Japanese method comprises the following steps: as shown in fig. 4, two scales (A, B) are set up at a distance of about 30m, and first readings are taken on the two scales from a measuring station (1) located in the middle of the line connecting the two scales. The measuring station (2) is arranged at the position about 3m outside the scale (A), and the calculation formula of the angle i is as follows:
in the middle of、/>、/>、/>The readings of the two scales (A, B) observed by the digital level at 1 and 2 respectively, and S is the distance between the two scales (A, B).
However, during the verification process, instruments of different manufacturers are often encountered, so that the bar code scale of different manufacturers needs to be switched for use, and two problems exist: 1. the code scale needs to be replaced, so that the workload is increased, and time is wasted greatly. 2. The absolute perpendicularity of the rack is guaranteed when the code ruler is installed, but the rack is inevitably not perpendicular when the rack is replaced manually, and meanwhile, the workload is increased due to careful arrangement.
The vision distance error of the digital level is the vision distance measurement error of the digital level, it is to choose two points with distance of 10m, 30m in a flat place, each position a ruler post, after setting up the digital level to be examined, use the horizontal distance D of the vertical ball point to ruler post point of the accurate measurement instrument of II grade steel tape 0 And recording, then measuring the horizontal distance from the plumb point to the column point of the instrument for a plurality of times by using the digital level gauge to be detected, and calculating the tie value D Are all Then, the line-of-sight distance measurement error of the inspected digital level is D Are all - D 0 However, in practice, it is difficult to accurately set the posts at positions just 10m and 30m, and thus the horizontal distance D measured by the class II steel tape 0 The distance is often not an integer, which brings a certain trouble to measurement and calculation, and is easy to cause larger measurement error and influence the accuracy of verification.
