Description

[0002] In the field of construction engineering, ensuring the flatness of the ground is one of the key indicators of construction quality, which directly affects the smooth progress of subsequent construction and the final quality of the building. Traditional ground flatness measurement methods mainly rely on simple measuring tools, such as levels, tape measures, etc., or use more advanced laser scanning equipment. However, these methods are either cumbersome to operate and inefficient to measure, or expensive, and have limited applicability in complex environments. In particular, it is often difficult to obtain high-precision measurement results on-site with changeable construction environments and complex terrain.

[0003] In recent years, with the development of sensor technology, automatic control and Internet of Things technology, the demand for fast and accurate measurement of ground flatness has become increasingly prominent.

Existing measuring devices often have high requirements for the working environment. For construction sites with irregular terrain and many obstacles, their measurement range and efficiency will be greatly reduced. Although some high-end measuring equipment is powerful, it is complicated to operate and requires professional training to master it.

In combination with the resistance coil 323, the clamping slide unit 326, the current monitor and other electronic sensor components, the physical displacement is converted into a quantifiable electrical signal to achieve accurate measurement of the ground flatness. The central control chip receives the electrical signal, converts it into intuitive flatness data through algorithm processing, and displays it on the screen. It supports users to set and adjust equipment parameters through the control button 220, realizes intelligent operation, and solves the problems of large manual reading errors and complex operations.
