Abstract

The invention discloses an intelligent measuring tape capable of realizing multistage measurement; when a user needs to measure the length in multi-time in a multistage manner, the measuring mode of the intelligent measuring tape can be switched to a segmental measuring mode; after each segment of length is measured, a zero clearing button can be pushed so as to continuously measure, so the measuring tape needs not to be retrieved for segmental measurement, thus bringing great conveniences for users.

Description

technical field [0001] The invention relates to the technical field of intelligent tape measure, in particular to an intelligent tape measure capable of multi-segment measurement. Background technique [0002] Gray code belongs to reliability coding, which is a kind of coding method which minimizes errors. Because, although the natural binary code can be directly converted into an analog signal by a digital / analog converter, in some cases, for example, when converting from 3 to 4 in decimal, every bit of the binary code will change, which can cause the digital circuit to generate a large signal. large peak current pulses. The Gray code does not have this shortcoming. When it switches between adjacent bits, only one bit changes. It greatly reduces the confusion of logic when going from one state to the next. Since there is only one bit difference between two adjacent code groups of this kind of encoding, in the conversion between the linear displacement of the direction an...
