Abstract

The utility model relates to a real-time dynamic-measuring quick-positioning centering rod, which comprises a centering rod, and a compass is arranged at one side of a leveling bubble. By utilizing the characteristic of compass orientation, the utility model quickens the time of a deviation person searching for a point position, has more outstanding use effect when in open and non-reference operating environments and when a plane coordinate system and a north-south direction are in 90-degree multiple relation, and has the characteristics of low cost, convenient use and high efficiency.

Description

Real time dynamic measurement is located centering rod fast

Technical field

The utility model relates to a kind of centering rod of novel RTK (real time dynamic measurement) setting-out.

Background technology

Increasingly mature along with RTK (real time dynamic measurement) technology, it has obtained using widely in fields of measurement.It not only saves time, laborsaving, be not subjected to the restriction of time, weather conditions and point-to-point transmission intervisibility situation, and possess measuring accuracy height, advantage such as good in economic efficiency.The machine center and the electronics phase center of centering rod fixed point antenna generally do not overlap in actual measurement, and this error is very big to the influence of actual measurement.Chi person is run in the RTK setting-out need come mobile centering rod with the difference of intending the setting-out position coordinate by comparing the eyeball position, shortens the distance of eyeball position and plan layout point position, until reaching accuracy requirement.The time of general RTK setting-out centering rod fixed point mainly relies on the experience of running chi person, and particularly at operating environment spacious, no object of reference, the time of the race chi person fixed point that sense of direction is good can lack slightly, otherwise the time of then fixing a point is longer.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of real time dynamic measurement and locatees centering rod fast, can overcome above-mentioned the deficiencies in the prior art, and the realization centering rod is located fast.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of real time dynamic measurement is located centering rod fast, comprises centering rod, and leveling bubble one side is provided with a compass.

A kind of real time dynamic measurement that the utility model provides is located centering rod fast, utilize the characteristic of compass orientation, accelerated to run the time that chi person seeks a position, particularly in spacious, no object of reference operating environment and the planimetric coordinates system become with the north-south 90 spend multiples when concerning result of use more outstanding, have the advantages that cost is low, easy to use, efficient is high.

Fig. 2 is that the utility model A is to view.

Embodiment

In Fig. 1, a kind of real time dynamic measurement is located centering rod fast, comprises centering rod 2, and leveling bubble 5 one sides are provided with a compass 6.

Embodiment: real time dynamic measurement is located centering rod fast, is made up of centering rod 2 and compass 6 two parts.Centering rod 2 is provided with antenna 1, and centering rod 2 supports 3 by horizontal-associate and is connected with centering rod support 4, and horizontal-associate support 3 is provided with leveling bubble 5, is used for centering rod and flattens, and in leveling bubble 5 one sides, a compass 6 is installed side by side.The scheme of optimizing is that compass 6 has 360 ° of scales.

Before the setting-out, at first determine the angle of the used planimetric coordinates X of system coordinate axis and positive north orientation, a lot of self-defining coordinate system X coordinate axis overlap with positive north orientation, if do not overlap, then need calculate the size of angle.

During setting-out, enter the setting-out zone after, with centering rod 2 leveling, the bigness scale coordinate, judge and the position relation of intending the setting-out coordinate according to the actual measurement coordinate that the RTK data recorder shows, and move centering rod, fast the location according to the angle that calculates before compass 6 north orientation pointers and the setting-out.As suppose that the used planimetric coordinates X of system coordinate axis overlaps with the angle of positive north orientation, intending the setting-out coordinate is (X=1000, Y=1000), the bigness scale coordinate is (X=990, Y=980), then run chi person and can after north orientation is walked 10 meters, walk 20 meters according to the east orientation pointer to east orientation again, promptly arrive and intend layout point position general location according to compass north orientation pointer.With centering rod 2 levelings, the accurate measurement coordinate repeats above step until emitting the coordinate points position then.

The advantage that the utility model has after tested is simple and efficient to handle, use safety, cost of manufacture is low, efficient is high.

Claims

1. a real time dynamic measurement is located centering rod fast, comprises centering rod (2), it is characterized in that: leveling bubble (5) one sides are provided with a compass (6).
