Problems solved by technology

[0005] In the above measurement methods, since the measurer needs to operate the scale of the tape to extend out to align the two ends of the measurement position, and at the same time, the measurer needs to visually read the scale marks at both ends to obtain data, according to the spatial position of the scale and the body position of the measurer , easy to cause reading scale deviation, resulting in poor measurement accuracy and low convenience of measurement
As a result, defects such as low accuracy and poor convenience of measuring by tape measure in the prior art become technical problems that those skilled in the art need to solve

Embodiment 3

[0044] In the third embodiment, on the basis of the first embodiment, the detector is specifically defined as a photoelectric encoder, the photoelectric encoder includes a photoelectric encoder disk and a photoelectric converter, and the photoelectric encoder disk is set to be able to rotate synchronously with the turntable, thus, When the measuring bar is extended or retracted, the photoelectric encoder disc rotates synchronously, and the photoelectric converter acquires the optical signal released by the photoelectric encoder disc, and outputs an electrical signal, and then the electrical signal is converted to obtain the telescopic value.

[0045] For the photoelectric encoder in the third embodiment, it is defined as an orthogonal photoelectric encoder, so that the optical signal obtained by the photoelectric converter includes the moving direction information of the measuring bar, which can further ensure the accuracy of measurement.

Embodiment 4

[0046] In the fourth embodiment, for the output of the stretching value in the first embodiment, before outputting the stretching value, the method includes: receiving a trigger instruction of the first control key.

[0047] When the trigger command is received, the stretching value is output, and the output stretching value is the instant stretching value at the moment when the first control key sends out the trigger command.

[0048] In this embodiment, the output of the stretching value is limited to triggering the first control key, and the immediate stretching value is issued when a trigger command is generated. This enables the output scaling value to further ensure measurement accuracy.

[0049] Further, when the trigger instruction of the first control key is received, the telescopic value is announced through the loudspeaker, and the broadcasted telescopic value is the telescopic value at the moment when the first control key is triggered. It is also possible to trig...

Abstract

The invention relates to the technical field of measurement, in particular to a measuring method based on a tape measure. The method includes: acquiring an electrical signal output by the detector along with the expansion and contraction of the measurement bar; converting and obtaining the expansion and contraction value of the measurement bar according to the electrical signal; and outputting the expansion and contraction value. The measuring bar is stretched and stretched, and it measures and aligns the space position required for measurement. At the same time, the detector outputs the corresponding electrical signal with the stretching of the measuring bar, and the electrical signal is converted, and then the stretching value of the measuring bar is obtained. The expansion and contraction value obtained by signal conversion is consistent with the actual expansion and contraction value of the measurement bar, which reflects the measurement state of the measurement bar for the spatial position. Thus, the output scaling value can be read and used. The direction provided by this embodiment significantly improves the accuracy and convenience of measurement.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a measuring method based on a tape measure. Background technique [0002] In today's society, various measurement methods are widely used, among which, for the measurement of length, it is often measured by visually reading the measurement scale of the measuring ruler. [0003] In recent years, the convenience and accuracy of measuring length has become a design goal, and thus, improving the accuracy and convenience of measuring length has become a design goal. [0004] In the prior art, for measuring length, a tape measure is usually used, the scale with marked scale is pulled out, the scale is placed at both ends of the space or entity to be measured, and the reference scale for measurement is visually inspected and positioned by the measurer For example, the 0-point mark of the scale is positioned at one end of the measurement position, and when the other end of the measu...
