Abstract

The invention discloses an intelligent measuring tape capable of measuring circumference and a circumference measuring method thereof. When a user needs to measure the circumference, the measuring mode of the intelligent measuring tape is switched to a circumference measuring mode, the inward recessing part of the second casing of the intelligent measuring tape is attached to the part to be measured, and the measuring tape is drawn out of the intelligent measuring tape body until the measuring tape is buckled into the buckling groove of the measuring tape to complete the measurement. After the measurement is completed, the measuring reading of the circumference is remained in the intelligent measuring tape, a user can check the reading at any time without any others' help, so that the user feels convenient in use. Because the Gray codes are directly arranged on the measuring tape, the measuring tape repeatedly sets the Gray codes according to the specified period, each Gray code in a period has a black or white code of a certain width, the Gray codes on the measuring tape can be read by a reading device, the traditional scale reading method is replaced, and the reading stability is enhanced.

Description

technical field [0001] The invention relates to the technical field of intelligent tape measures, in particular to an intelligent tape measure capable of measuring circumference and a method for measuring circumference. 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...
