Description

Total stations (also called electronic tacheometers) are optical-electronic Surveying instruments for horizontal angle, vertical angle and Distance measurement, as well as for the calculation of 3D coordinates and Storage of the measurement results. The for these functions Required hardware parts are compactly built into the instrument and the control and display unit is also an integrated one Part of the instrument.

Previous Total stations usually have a "U-shape". Below is the display appropriate. Between the U-pillar is the optical telescope with integrated electro-optical distance meter and various electronic Hardware sharing (digit CCD camera, laser distance meter, pointfinder etc.). This traditional form allows (on today State of the art) barely the integration of more meaningful Measuring sensors more.

The Use of external measuring sensors is one possible solution but this implies the need for a second separate instrument with separate power supply, as well as data storage, compatibility, Operating and transport problems. This is also in contradiction to the basic principle of a total station, all functions in the device to integrate.

A fundamentally new form of total stations can be remedied by the Emergence of larger space around this additional Instruments also in the total station / Tachymeter to integrate.

These new form is the egg shape. In the upper third of the body - im further: headboard - (B) creates new space for the installation, and the integration of various sensors and instruments, which until now not or only externally used as a separate device could become.

This Headboard (B) is with, attached to its sides connecting terminals (C) easily removable and against another headboard with others Hardware part exchangeable.

Thereby the possibility arises, theoretically any number add more useful instruments variably to the total station, from which the emergence of a multifunctional surveying instrument results → hereinafter referred to as multi-station.

Geodetic Multistation is a total station (electronic tachymeter) with the optimal integration possibility of any further Sensors. Optimal integration means the perfect optical unit, the unified and shared power, data storage, Operation and communication with the main instrument (A) and the fast modular interchangeability of the different modules.

This new design (egg shape) also has more advantages over the old U-shape, namely the absence of corners, edges and hardly protruding controls. Beneficial for measuring stability and thus measuring accuracy in the wind, less risk of demolition of outstanding Share with fall of the device. (see design application Act.

The main instrument (A) has its electronic interface laterally at the top edge of the additional instrument (head part (B)), the additional instrument laterally down so arranged that this C-clamp (C) as small as possible (5-6 cm maximum) can be , One end of the clamp (C) can be mounted in one of the two parts (better in the head part) so that it is not removable, but at the same time rotatable and easily pulled out. This has the advantage that it can not be lost. If the connection fails, the clamp can be turned by 90 ° and the free end can be inserted into a protective hole (E) provided so that it fits snugly against the device and can not break off. When connecting to the main instrument (A), pull the free end out of the protective hole (E), turn it 90 ° downwards and insert it into the interface of the main unit (A). (please refer 2 )

Of the in protection claim 4 specified development solar head is the Problem that most measurement tasks in surveying in Outdoors, without electricity and possibly even without a vehicle in the Take place nearby and the batteries are not recharged can.

Remedy the located on the surface of the head part solar cell modules (S). These solar cell modules (S) are mounted there so that only the upper edge of the solar modules are attached, the lower edge is detachable and hinged up to achieve better efficiency of the solar cell, even on the side facing away from the sun side of the head part. The solar modules enable the power supply of the instrument or the charging of the batteries, during and outside the measuring operation. In addition, the use of solar power enables environmentally friendly operation of the instrument, and saves electricity. (please refer 5 )

Of the in protection claim 5 specified development is the following problem underlying: Geodetic total stations have one or two integrated in the telescope electro-optical distance meter or Laser distance meter, which housed there coaxially (in the optical axis) are. This arrangement is the optimal solution, but technically complex and therefore expensive. To a cheaper one To create a solution, you can get a cheap handheld laser meter in the Integrate header (B) for easier measuring z. B. in construction provides sufficient results.

in the Head section (B) of the geodesic multistation leaves one (offered by several manufacturers for years) Hand laser distance meter (L) integrate the distance measurement on natural surfaces allows. The Housing of the laser distance meter (L) in the head section (B) fixed (not tiltable) to be installed so that when leveling of the main instrument (A), the laser distance meter also horizontal stands. For distance measurement above or below the horizontal Plane, the laser beam (the distance meter) of the main instrument (A) so controlled that the always parallel to the finish line of the telescope (F) stands.

Around the design-related height offset between optical Correcting the sighting line of the telescope (F) and laser aiming line and directing the laser beam to the point targeted by the telescope becomes when triggering the distance measurement first a rough (cm-exact) measurement made. After that, the vertical angle correction calculated mathematically and the vertical position of the laser beam corrected by the value (tilted down).

After that the fine measurement (mm-exact) is automatically started and the result shown on the display.

In order to be able to measure distances upwards (measurement of ceiling heights) or downwards (measurement of instrument height above ground) with this laser distance meter (L), it is pulled out horizontally from the head part (B). In this state, the tail of the laser distance meter is tilted 90 ° down or up to perform distance measurement vertically. Another technical solution is to deflect the laser beam vertically by means of a deflection prism. ( 7 )
