Abstract

The invention relates to the technical field of measurement, in particular to an intelligent ruler. The intelligent ruler comprises a rectilinear scale and is characterized in that a resistor string is arranged on the rectilinear scale; each resistor pin in the resistor string extends outwards to form a contact; the contacts are sequentially distributed on a scale port of the rectilinear scale; a conductive layer is also arranged on the scale port, so that when a conductive pen point draws at the scale port, the contacts are conducted with the conductive layer; the conductive layer is connected with an AD (Analog to Digital) conversion module; the AD conversion module is connected with a singlechip; and the singlechip is also connected with a key module and a display module. According to the invention, a conventional ruler is subverted and a user can know the reading number only by drawing without visual observation.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to an intelligent ruler. Background technique [0002] Traditional rulers have a variety of shapes, including tape measure, ruler, and folding ruler. However, these rulers must be read manually when measuring, so that not only there are visual errors, but also there is a huge gap when measuring the scale of high places. inconvenient. With the current automation, digitization, and integration have become the development trend of electronic products. How to realize a kind of ruler that reads length automatically is the demand of the market. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent ruler, which does not require visual inspection, but only needs to be drawn with a conductive pen tip to know the reading. [0004] The present invention is realized by the following scheme: an intelligent ruler, comprising a ruler, charact...
