Multifunctional electronic ruler

Abstract

The invention discloses a multifunctional electronic ruler and aims to provide a multifunctional electronic ruler high in measurement accuracy and powerful in measurement function. The multifunctional electronic ruler comprises a housing, an infrared distance measurement mechanism, a roller distance measurement mechanism and a measuring tape distance measurement mechanism, wherein the infrared distance measurement mechanism, the roller distance measurement mechanism and the measuring tape distance measurement mechanism are arranged in the housing and are electrically connected with a central processing unit arranged in the housing, the central processing unit is also electrically connected with a display screen and an input module which are arranged on the housing, a power supply module electrically connected with the central processing unit is also arranged in the housing, the measuring tape distance measurement mechanism comprises a storage wheel and a measuring tape coiled on the storage wheel, the measuring tape bypasses the measuring wheel arranged in the housing to extend to the outside of the housing and rotates with the measuring tape synchronously, and a rotation speed sensor is arranged on one side of the measuring wheel. The multifunctional electronic ruler is applied to the technical field of electronic measuring tools.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a multifunctional electronic ruler. Background technique [0002] As a traditional measuring tool, a ruler is generally used to measure length. Commonly used rulers include a tape measure, a ruler, and the like. But the use of these rulers has great limitations. For example: 1. The measurement length is limited. When the measurement distance is long, the roll paper and ruler cannot complete the measurement at one time. It is not only troublesome to perform multiple measurements, but also affects the accuracy of the measurement; 2. It can only measure straight-line distances, and the tape measure 1. The ruler cannot measure the distance of irregular curves and some spaces that are inconvenient to measure; 3. The measurement accuracy is limited. The measurement accuracy of the tape measure and ruler is not only affected by the measurement environment, but at the same time, the tape measure and ...

However, the use of these rulers has great limitations

For example: 1. The measurement length is limited. When the measurement distance is long, the roll paper and ruler cannot complete the measurement at one time. It is not only troublesome to perform multiple measurements, but also affects the accuracy of the measurement; 2. It can only measure straight-line distances, and the tape measure 1. The ruler cannot measure the distance of irregular curves and some spaces that are inconvenient to measure; 3. The measurement accuracy is limited. The measurement accuracy of the tape measure and ruler is not only affected by the measurement environment, but at the same time, the tape measure and ruler need manual reading, which is not possible. avoid thinking error
