Description
Technical field
The utility model relates to a kind of surveying instrument, specifically, relates to a kind of built-in height measuring device and can measure the surveying instrument of its place height.
Background technology
Existing surveying instrument, such as total powerstation, transit etc., its high measurement is then mainly measured and is calculated and get by manual measurement or to another known point.Manual measurement is that the operating personnel by surveying instrument adopt steel tape to measure from the point of the center mark on the instrument cover plate to the height the survey station point.The precision of manual measurement is relatively poor, comparatively carefully also still can there be several millimeters error even measure, and because center mark point and survey station point be not often on same pedal line, so adopt the approximate measure point, and approximate measure point and survey station point may be at the same level faces, so can there be certain error in high measurement.By then being to place prism at known point to the measurement of known point and inverse height of instrument, then measure distance and an angle that plays prism, height by measured distance, angle and known point comes computing equipment apart from the height of bottom surface again, this method is subject to the impact of setting-out error and external environment, and work efficiency is lower.
Summary of the invention
The purpose of this utility model provides a kind of surveying instrument that can carry out fast and accurately position correction and high measurement.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of surveying instrument of built-in height measuring device is provided with the main circuit of control survey work in this surveying instrument, it is characterized in that: be built-in with in the described surveying instrument and measure its height measuring device apart from the height of survey station point; Described height measuring device comprises to the Laser emission assembly of the direction Emission Lasers signal of described survey station point, detect and receive the laser pick-off detection components of the heliogram of laser signal behind described survey station point that described Laser emission assembly sends, the described heliogram that the laser signal that sends by described Laser emission assembly and described laser pick-off detection components receive calculates the high circuit of survey of distance, the high circuit of described survey respectively with described Laser emission assembly, described laser pick-off detection components, described main circuit is connected, and described Laser emission assembly is arranged at the center of described surveying instrument.
Preferably, described surveying instrument includes but not limited to total powerstation, transit, plumb aligner, spirit-leveling instrument.
Preferably, described surveying instrument is provided with vertical pivot, and described Laser emission assembly and described vertical pivot same axis arrange.
Because technique scheme is used, the utility model compared with prior art has following advantages: the built-in height measuring device that can measure height of instrument in the surveying instrument of the present utility model, by its high measurement that can realize fast and accurately instrument, can increase substantially operating accuracy and work efficiency.

Embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Embodiment one: shown in accompanying drawing 1, to surveying instrument 1 measuring height the time, center and the ground survey station point 2 of surveying instrument 1 need to be placed on the same pedal line, and measure height distance between the two.And existing method has larger error usually and efficient is lower, therefore, existing surveying instrument 1 is improved, and can carry out fast and accurately height and measure.
A kind of surveying instrument of built-in height measuring device, the surveying instrument 1 of indication includes but not limited to the kinds such as total powerstation, transit, plumb aligner, spirit-leveling instrument, is provided with the main circuit of control survey work in this surveying instrument 1, is provided with vertical pivot in the surveying instrument 1.Shown in accompanying drawing 2, be built-in with in this surveying instrument 1 and measure its height measuring device apart from the height of survey station point.Height measuring device comprise the laser signal that sends to the Laser emission assembly of the direction Emission Lasers signal of survey station point, detection and reception Laser emission assembly through the laser pick-off detection components of the heliogram behind the survey station point 2, be sheathed on pedestal on Laser emission assembly and the laser pick-off detection components, the high circuit of survey that heliogram that the laser signal that sends by the Laser emission assembly and laser pick-off detection components receive calculates distance; Survey high circuit and be connected with Laser emission assembly, laser pick-off detection components, main circuit respectively, main circuit is connected with the high circuit of survey by its communication interface.The Laser emission assembly is coaxial and be positioned at the center of surveying instrument 1 with vertical pivot.
Shown in accompanying drawing 3, when this surveying instrument is highly measured, start simultaneously Laser emission assembly and laser pick-off detection components.After the instrumentation personnel flatten surveying instrument 1, open height measuring device, after first surveying instrument 1 being carried out position correction, adopt again Laser emission assembly Emission Lasers signal and adopt the laser pick-off detection components to receive heliogram, and utilize and survey high circuit calculates surveying instrument 1 according to the difference of above-mentioned laser signal and heliogram height, and the height value that will calculate gained transfers in the main circuit, to carry out follow-up work, can increase substantially measuring accuracy and work efficiency.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
