DE202006012703U1 - Astrological GOTO-mounting and laser distance measuring instrument e.g. tachymeter, combination for e.g. star observation, has mounting moved with keys, such that beam produced by measuring instrument is navigated on point to be measured - Google Patents

Abstract

The combination has a laser distance measuring instrument mounted or fastened within an area of a telescope retainer of an astrological GOTO-mounting. The mounting is equipped with a controller, motor and an angle transmitter for automatic tracking of a fixed celestial object. The measuring device is switched on for producing permanent, bright luminous laser beam, where the mounting is moved with keys in a personal computer, such that the laser beam is navigated on a point to be measured.

Description

Of the Tachymeter - one Theodolite with odometer - is the traditional meter in the Surveying. It is an angle distance measuring device. With this Meter can be three dimensional points are measured. Manufacturer of such total stations are e.g. the companies Bosch, Hilti, Nikon and Leica.

to The market now offers measurement of geometries and objects a series of special software solutions at (http://www.kubit.de/, http://www.aadiplan.de/, http://www.elcovision.com, http://www.vitruvius.de/. The coordinates are measured with these tachymeters and then transferred to the special software. The combination of a tachymeter and a special software allows for example the measurement of buildings or rooms or a local one Allowance.

Of the major disadvantage of this Tachymeter consists in the price of the products. These are usually not to get under 7,000-EUR. The combination a tachymeter and special software (e.g., for the building survey) is appropriate expensive. Due to the high investment is the entry into the digital Aufmasstechnik for smaller companies often not possible. Another disadvantage is that these tacheometers are not motor, but can only be moved by hand. The projection of a calculated or constructed or calculated in software Point over the tachymeter is not possible.

Of the in claim 1 protection invention is based on the problem a cost-effective and to create a motorized tachymeter. This tachymeter intended as a measuring instrument for all Measurements and can be used as a projection system.

This Problem is with the protection listed in claim 1 combination of an astrological GOTO mount and a laser distance measuring device solved.

Astrological Mounts are for used the star observation. An astrological mount is a rotary-swivel unit, on which the telescope is mounted. About this rotary-swivel unit the telescope can be guided very well become.

The trend is increasingly towards the so-called "GOTO mounts." An embodiment is in the 1 shown. These electronic mounts are equipped with a controller, motors and encoders. Among other things, they allow the automatic tracking of a fixed sky object via the motors. The fixed celestial object thus always remains in the field of view of the telescope.

In Connection to a PC and appropriate software, the GOTO mounts selected Approach celestial objects automatically. About the software determines the User the celestial object he wants to see and The mount then positions exactly on the chosen celestial object.

Of the User also has the option with the keys on the PC or an external control unit mount manually turn and pan. It can thus be e.g. one unknown to him Fix the sky object. The software on the PC can now be the exact one Query the angle and swivel angle of the angle encoders and thus determine the sky object, which the user started.

If the telescope is replaced by a conventional laser distance measuring device, it is possible to calculate a three-dimensional space vector (x, y, z) on the basis of the rotation and swivel angle of the mount and the measured distance of the laser distance measuring device. Thus, any, three-dimensional objects can be measured. This corresponds to the operation of a tachymeter. The reverse way is also possible. The device can approach a defined point and project over the laser beam. An embodiment is in the 2 shown.

The Measuring a point looks like this: The Laser distance meter is switched on. This then produces a permanent, bright glowing Laser beam. Use the buttons on the PC to move the mount and thus the laser beam is driven to the point to be measured become. Has the user fixed the point to be measured exactly, the measurement is over one Button on the PC triggered. The software receives the both angular positions (rotation and tilt angle) of the mount and the laser distance meter determined distance. Based on these values, the software calculates the Point coordinates (x, y, z).

Of the Users also have the opportunity to themselves Defined points to be displayed by the laser. These points can for example constructively determined in the software. The mount drives the corresponding position and the laser beam projects this Point on a surface.

This device can be used to solve a wide variety of surveying tasks. Façade and interior measurements, building surveys, floor plans, equipment surveying, archae ological stakeout, etc. The invention allows the measurement of other (stationary) objects.

Farther The system can also be used as a projection system.

The Digital processing technology will continue to spread through this invention, since with this invention Aufmasssysteme can be offered, the significantly below the price level of current systems. Consequently Smaller companies will also be able to get started in this technology.
