Abstract

The invention discloses a kind of method for measuring total powerstation height.This method uses the principle of reflection of light.By total powerstation measurement basic point on to middle leveling after, away from measurement basic point at a certain distance from establish on a vertical Sopwith staff, Sopwith staff place one piece of refractive body.Moved up and down by refractive body along Sopwith staff can be observed from total powerstation eyepiece basic point in refractive body into picture, angled relationships can obtain total powerstation trunnion axis to the distance of basic point, i.e. height of instrument between angle of light and angle of reflection relation of equality and parallel lines.The principle of the invention is simple clearly, material cheap and simple, easy to operate, precision are high, easy grasp, be easy to engineering application.

Description

A kind of method for measuring total powerstation height
Technical field
The invention belongs to engineering measuring technology field, more particularly to a kind of method for measuring total powerstation height.
Background technology
At present measurement total powerstation height of instrument method mainly with steel ruler direct measurement basic point to total powerstation side away from From, then by certain triangle conversion obtain height of instrument.The method measurement error is larger, and human factor influence is big, it is impossible to full Sufficient engineering survey high-precision requirement.
The content of the invention
The purpose of the present invention be overcome the deficiencies in the prior art there is provided it is a kind of measure total powerstation height method.
The thinking of the present invention:With the principle of reflection of light, pressed from both sides between angle of light and angle of reflection relation of equality and parallel lines Angular dependence can obtain total powerstation trunnion axis to the distance of basic point, that is, draw total powerstation height.
Concretely comprise the following steps:
Simultaneously centering leveling above basic point D when total powerstation to be placed in measurement, A points are total powerstation horizontal axis and vertical axis Intersection point, the Sopwith staff with vertical level bubble is stood on into position of 0.95~1.05 meter away from total powerstation and adjusted to vertical, is kept Sopwith staff is parallel with the vertical axis of total powerstation, then total powerstation is adjusted into level, and marks total powerstation object lens crosshair horizontal hair in tower The intersection points B of projection line and Sopwith staff on chi, then B points put the refractive body of one piece of 10 centimetres of diameter on Sopwith staff, and refractive body is from B points Slow slide downward, while total powerstation sight is slowly moved down with refractive body, when can observe that D points exist in total powerstation eyepiece In refractive body into picture when, refractive body stops movement, and regulation total powerstation makes object lens crosshair intersection point be directed at D points in refractive body Picture, fixed total powerstation, takes refractive body away, and the intersection point C of projection line and Sopwith staff of the now object lens crosshair horizontal hair on Sopwith staff is marked Go out, the distance of B and C point-to-point transmissions is measured with straight steel rulerFrom the principle of reflection of light, ∠ ACE=∠ DCE=∠ BAC,The as height of total powerstation.
The Sopwith staff used in the present invention can be replaced with other controllable vertical means.
Compared with prior art, the beneficial effects of the invention are as follows:Simple clear and definite, the material cheap and simple of the principle of the invention, behaviour Make easy, precision height, easily grasp, be easy to engineering application, be easy to large-scale promotion.
Brief description of the drawings
Fig. 1 is the flat measuring intention of total powerstation in the embodiment of the present invention.
Fig. 2 is that total powerstation tiltedly measures intention in the embodiment of the present invention.
Marked in figure:1- total powerstations;2- foot stools;3- Sopwith staffs;4- level crossings.
Embodiment
Below in conjunction with specific embodiment, the present invention will be described in detail, so that advantages and features of the invention can be more easy to It is readily appreciated by one skilled in the art.
Embodiment:
Refer to Fig. 1, Fig. 2, the present embodiment is concretely comprised the following steps:
Simultaneously centering leveling above basic point D when total powerstation 1 to be placed in measurement by foot stool 2, A points are the trunnion axis of total powerstation 1 The intersection point of line and vertical axis, stands on position of 1 one meters away from total powerstation by the Sopwith staff 3 with vertical level bubble and adjusts to vertical Directly, keep Sopwith staff 3 parallel with the vertical axis of total powerstation 1, then total powerstation 1 is adjusted to level, and mark the object lens cross of total powerstation 1 The intersection points B of projection line and Sopwith staff 3 of the silk horizontal hair on Sopwith staff 3, then B points put the plane of one piece of 10 centimetres of diameter on Sopwith staff 3 Mirror 4, level crossing 4 is from the slow slide downward of B points, while the sight of total powerstation 1 is slowly moved down with level crossing 4, when the mesh of total powerstation 1 Can be observed in mirror D points in level crossing 4 into picture when, level crossing 4 stop movement, regulation total powerstation 1 make object lens crosshair The picture of D points in intersection point alignment surface mirror 4, fixed total powerstation 1, takes level crossing 4 away, will now object lens crosshair horizontal hair in Sopwith staff 3 On the intersection point C of projection line and Sopwith staff 3 mark, the distance of B and C point-to-point transmissions is measured with straight steel rulerCan by the principle of reflection of light Know, ∠ ACE=∠ DCE=∠ BAC,The as height of total powerstation 1.

Claims (2)

1. a kind of method for measuring total powerstation height, it is characterised in that concretely comprise the following steps:
Simultaneously centering leveling above basic point D when total powerstation to be placed in measurement, A points are the friendship of total powerstation horizontal axis and vertical axis Point, stands on position of 0.95 ~ 1.05 meter away from total powerstation by the Sopwith staff with vertical level bubble and adjusts to vertical, keep Sopwith staff with The vertical axis of total powerstation is parallel, then total powerstation is adjusted into level, and marks total powerstation object lens crosshair horizontal hair on Sopwith staff The intersection points B of projection line and Sopwith staff, then B points put the refractive body of one piece of 10 centimetres of diameter on Sopwith staff, refractive body from B points it is slow to Lower slider, while total powerstation sight is slowly moved down with refractive body, when can observe D points in refractive body in total powerstation eyepiece It is middle into picture when, refractive body stops movement, and regulation total powerstation makes object lens crosshair intersection point be directed at the pictures of D points in refractive body, fixed Total powerstation, takes refractive body away, and the intersection point C of projection line and Sopwith staff of the now object lens crosshair horizontal hair on Sopwith staff is marked, steel is used Ruler measures the distance of B and C point-to-point transmissions, from the principle of reflection of light, as=2, the height of total powerstation.
2. the method for measurement total powerstation height as claimed in claim 1, it is characterised in that Sopwith staff is with other controllable vertical means Instead of.
