3 Overview
The all-station electronic speedometer is a combination of automatic ranging, angle measurement, calculation and automatic data recording and transmission.
Automated, digital 3D coordinate measurement and positioning system. It consists of photoelectric distance measuring unit, electronic angle measuring and microprocessor
Unit, and electronic recording unit, is widely used in control measurement, topographic survey, cadastre and real estate survey
Electronic measuring instruments for volume, industrial measurement and offshore positioning. According to its structure, it can be divided into two types. integral type and building block type.
The former is designed to integrate the ranging and angle measurement with the optical and mechanical systems of the electronic computing unit and the instrument;
It consists of independent photoelectric distance measuring heads, electronic theodolites and electronic computing units.
The all-station electronic speed measuring instrument is also called "Electronic Total Station" (Electronic Total Station), referred to as "Total Station".
The angle measurement part of the total station and the accuracy level of the electronic theodolite are divided by the nominal standard deviation of the instrument, see table
1.
Table 1 Accuracy classification
Instrument Level I II III IV
Nominal standard deviation 0.5′′ 1.0′′ 1.5′′ 2.0′′ 3.0′′ 5.0′′ 6.0′′ 10.0′′
Standard deviation range of each level mβ≤1.0′′ 1.0′′ \u003cmβ≤2.0″ 2.0″\u003cmβ≤6.0″ 6.0″\u003cmβ≤10.0″
Note. mβ is the standard deviation of the angle measurement.
4 Metrological performance requirements
4.1 Alignment rotation correctness
See Table 2 for the correctness of the rotation of the sighting department.
4.2 Telescope boresight and horizontal axis perpendicularity
