Problems solved by technology

The structure of the existing measuring ruler is mechanical, and it is particularly susceptible to the influence of external forces to affect the measurement results, such as collisions, magnetic fields, etc.
In addition, the existing measuring ruler determines the measurement result by indicating the scale value through the pointer, and the marking of the scale line is affected by the measurement range and the visual line width, so it is impossible to mark it too finely, so there is an estimated value when reading, And when reading, because of different visual angles, it will also bring a certain deviation.

Abstract

The invention relates to the technical field of engineering measurement, particularly, relates to a measuring scale. The measuring scale includes a first ruler, a second ruler, a hinge, an inclination angle sensor, a display device, and a processor. the first ruler and the second ruler are hinged by a hinge to achieve folding or unfolding, the inclination angle sensor, the display device and the processor are disposed on the first ruler, the display surface of the display device is far away from the first ruler, the inclination angle sensor and the display device are electrically connected with the processor, the inclination angle sensor is used to measure the included angle between the building surface and the reference surface when the first ruler and the second ruler are attached to the building surface, the processor is used to calculate an error value between the building surface and the building reference surface according to the included angle value, the length of the first ruler, and / or the length of the second ruler, and display the error value via the display device. The measuring scale is high in measurement accuracy.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to a measuring ruler and a measuring method. Background technique [0002] In the prior art, the measuring ruler uses the principle of gravity, drives the pointer with the swing of the pendulum, and sets the scale evenly within the corresponding swing range to indicate the range of deviation. The scale indicated by the stop of the pointer indicates the The deviation value of the measuring surface from the standard vertical surface. The structure of the existing measuring ruler is mechanical, which is particularly susceptible to the influence of external forces to affect the measurement results, such as collisions, magnetic fields, and the like. In addition, the existing measuring ruler determines the measurement result by indicating the scale value through the pointer, and the marking of the scale line is affected by the measurement range and the visual line width, ...
