Abstract

The present invention discloses a method for measuring the height of a theodolite. According to the method, the light reflection principle is used, a vertical stadia rod is established a certain position away from a measuring base point after the theodolite is subjected to centering leveling on the measuring base point, a light reflection body is placed on the stadia rod, the base point image formed in the light reflection body can be observed from the theodolite eye lens through the movement of the light reflection body up and down along the stadia rod, and the distance between the theodolite horizontal axis to the base point can be calculated through the light incident angle and the reflection angle equal relationship and the included angle relationship between the light incident angle and the parallel line, wherein the distance is the height of the theodolite. The method of the present invention has advantages of simple and clear principle clear, simple and cheap material, simple operation, high precision, easy grasping, and easy engineering use.

Description

A kind of method of surveyor's transit height
Technical field
The invention belongs to engineering measuring technology field, particularly a kind of method of surveyor's transit height.
Background technology
The method of current surveyor's transit height of instrument mainly directly measures the distance of basic point to transit side with steel ruler, then obtains height of instrument through certain triangle conversion.The method measuring error is comparatively large, and human factor impact is large, can not meet engineering survey high-precision requirement.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of method of surveyor's transit height is provided.
Thinking of the present invention: use the principle of reflection of light, by angle of light and between reflection angle relation of equality and parallel lines angled relationships can obtain the distance of transit transverse axis to basic point, namely draw transit height.
Concrete steps are:
Also centering leveling above basic point D when transit being placed in measurement, A point is the intersection point of transit horizontal axis and vertical axis, the Sopwith staff of band vertical level bubble is stood on the position apart from 0.95 ~ 1.05 meter, transit and is adjusted to vertical, keep Sopwith staff parallel with the vertical axis of transit, again transit is adjusted to level, and mark the projection line of transit object lens crosshair horizontal hair on Sopwith staff and the intersection points B of Sopwith staff, then on Sopwith staff, B point puts the refractive body of one piece of diameter 10 centimetres, refractive body is from the slow slide downward of B point, transit sight line slowly moves down with refractive body simultaneously, when the picture that D point becomes in refractive body can be observed in transit eyepiece, refractive body stops mobile, transit is regulated to make object lens crosshair intersection point aim at the picture of D point in refractive body, fixing transit, take refractive body away, the intersection point C of projection line on Sopwith staff of now object lens crosshair horizontal hair and Sopwith staff is marked, the distance of B and C point-to-point transmission is measured with straight steel ruler from the principle of reflection of light, ∠ ACE=∠ DCE=∠ BAC, be the height of transit.
The Sopwith staff used in the present invention can replace with other controlled vertical means.
Compared with prior art, the invention has the beneficial effects as follows: the principle of the invention is simple clear and definite, material cheap and simple, easy and simple to handle, precision is high, easy grasp, be convenient to engineering application, be easy to large-scale promotion.
Accompanying drawing explanation
To be that in the embodiment of the present invention, transit is flat measure intention to Fig. 1.
Fig. 2 is that in the embodiment of the present invention, transit tiltedly measures intention.
Mark in figure: 1-transit; 2-foot rest; 3-Sopwith staff; 4-level crossing.
Embodiment
Below in conjunction with specific embodiment, the present invention will be described in detail, can more easily be readily appreciated by one skilled in the art to make advantages and features of the invention.
Embodiment:
Refer to Fig. 1, Fig. 2, the concrete steps of the present embodiment are:
Above basic point D when transit 1 is placed in measurement by foot rest 2 and centering leveling, A point is the intersection point of transit 1 horizontal axis and vertical axis, the Sopwith staff 3 of band vertical level bubble is stood on the position apart from 1 one meters, transit and is adjusted to vertical, keep Sopwith staff 3 parallel with the vertical axis of transit 1, again transit 1 is adjusted to level, and mark the projection line of transit 1 object lens crosshair horizontal hair on Sopwith staff 3 and the intersection points B of Sopwith staff 3, then on Sopwith staff 3, B point puts the level crossing 4 of one piece of diameter 10 centimetres, level crossing 4 is from the slow slide downward of B point, transit 1 sight line slowly moves down with level crossing 4 simultaneously, when the picture that D point becomes in level crossing 4 can be observed in transit 1 eyepiece, level crossing 4 stops mobile, transit 1 is regulated to make the picture of D point in object lens crosshair intersection point alignment surface mirror 4, fixing transit 1, take level crossing 4 away, the intersection point C of projection line on Sopwith staff 3 of now object lens crosshair horizontal hair and Sopwith staff 3 is marked, the distance of B and C point-to-point transmission is measured with straight steel ruler from the principle of reflection of light, ∠ ACE=∠ DCE=∠ BAC, be the height of transit 1.

Claims (2)

1. a method for surveyor's transit height, is characterized in that concrete steps are:
Also centering leveling above basic point D when transit being placed in measurement, A point is the intersection point of transit horizontal axis and vertical axis, the Sopwith staff of band vertical level bubble is stood on the position apart from 0.95 ~ 1.05 meter, transit and is adjusted to vertical, keep Sopwith staff parallel with the vertical axis of transit, again transit is adjusted to level, and mark the projection line of transit object lens crosshair horizontal hair on Sopwith staff and the intersection points B of Sopwith staff, then on Sopwith staff, B point puts the refractive body of one piece of diameter 10 centimetres, refractive body is from the slow slide downward of B point, transit sight line slowly moves down with refractive body simultaneously, when the picture that D point becomes in refractive body can be observed in transit eyepiece, refractive body stops mobile, transit is regulated to make object lens crosshair intersection point aim at the picture of D point in refractive body, fixing transit, take refractive body away, the intersection point C of projection line on Sopwith staff of now object lens crosshair horizontal hair and Sopwith staff is marked, the distance of B and C point-to-point transmission is measured with straight steel ruler from the principle of reflection of light, ∠ ACE=∠ DCE=∠ BAC, be the height of transit.
2. the method for surveyor's transit height as claimed in claim 1, is characterized in that other controlled vertical means of Sopwith staff replaces.
