Leveling scale based on light interception sensor part and laser

Abstract

The invention relates to a leveling scale based on a light interception sensor part and laser. The leveling scale comprises a casing, a linear measuring part, a measuring rod, the light interception sensor part, an output control part, a display part, a fixing part and a measured value transmitting part, wherein the casing is formed in the length direction; the linear measuring part is arranged at the lower part of the casing, a scroll and a measuring belt are arranged in the linear measuring part, and the measuring belt is introduced in or led out in a vertical line when in a state of winding around the scroll; the measuring rod is connected with the front end of the measuring belt of the linear measuring part and is introduced in or led out in the vertical line along the inside of the casing; the light interception sensor part is combined with the measuring rod; the output control part reads the measuring belt led out of the linear measuring part according to an introducing-in or leading-out distance of the measuring rod, performs operation and outputs a measured value; the display part is arranged on the upper front of the casing and displays the output value of the output control part; the fixing part is arranged on the side surface of the casing and the measuring rod and fixes the position of the measuring rod after the measuring rod is introduced into or led out of the casing; the measured value transmitting part transmits the measured value output by the output control part to a mobile terminal of a worker.

Description

technical field [0001] The present invention relates to a level measuring instrument, in particular, to a level measuring scale. When using a light receiving sensor unit and a laser to measure the level of a construction floor or road surface at a civil engineering or construction site, etc., only one worker can Accurate measurement can be realized. Background technique [0002] Leveling is a method of measurement used to determine terrain heights, and the benchmarks for all heights are based on the national benchmarks specified by each country. [0003] Precision leveling is precisely measured by a leveling instrument. After erecting scales marked with high and low scales in front and behind the direction of travel, the height difference between the two points is set, and the measurement is carried out while walking towards the point to be measured. [0004] Usually, when performing leveling, a leveling instrument is installed, a scale is erected at a measurement position ...

Problems solved by technology

[0009] In addition, the scale needs to be raised and lowered according to the measurement position of the level. Most of the scales have a double structure and a triple structure. They are drawn out and placed on the scale for measurement. Since the staff cannot accurately read the drawn out, it is lifted to a considerable height. Therefore, there are problems such as reducing the construction accuracy and reliability
