Problems solved by technology

[0005] However, this method can only deal with the measurement work with a small workload. When the workload of the measurement is large, it is not competent only by manually pressing the reset switch. If the manual reset is not performed, the previously measured data will be lost. Interference with subsequent measurement data and accumulate errors

Abstract

The invention discloses a zero-point resetting method of an electronic measuring tape. The method comprises: a measuring tape stretches out and draws back and an erasing module is activated when the measuring tape draws back into a housing each time; the erasing module sends a measurement data zero-clearing instruction to a processor; and the processor receives the instruction sent by the erasing module and carries out zero clearing on the measurement data. According to the method, because the erasing module is activated when the measuring tape draws back into the housing each time, the processor will carry out measurement data zero clearing automatically when the measuring tape draws back into a housing after an operator finishes measurement work one time. Therefore, when the operator carries out measurement work next time, the initial measurement data are set to be zero, thereby causing no influence on the subsequent measurement data and thus avoiding an error accumulation phenomenon due to too many times of measurement. Moreover, zero clearing is carried out automatically when the measuring tape draws back, thereby reducing the workload of the operator substantially.

Description

technical field [0001] The invention relates to the field of measurement and control technology and instruments, in particular to a method for resetting the zero point of an electronic tape measure. Background technique [0002] With the development of China's precision instruments and measuring equipment, more and more advanced measuring instruments are gradually being widely used. [0003] At present, in the occasions that people need to use measuring instruments in their daily life, they often only need to use simple measuring tools such as rulers and tape measures to meet the requirements. However, in some cases where measurement accuracy is required and the measurement workload is large, manual use of rulers, tape measures and other tools is not sufficient. For this reason, electronic tape measures have appeared on the market, which are controlled by electronic components, and their measurement accuracy is high. Compared with manual measurement, electronic tape measure...
