Intelligent steel rule

Abstract

The invention discloses an intelligent steel rule, and the steel rule comprises an installation box and a control box which is fixed on a side surface of the installation box. The upper surface of the control box is provided with a display screen and a loudspeaker. The inner wall of the installation box is provided with a reel, and the reel is provided with a flexible rule. The flexible rule is provided with Gray codes in a pasted manner. The front end of the upper surface of the installation box is provided with a cross bar, and the lower end of the cross bar is provided with an induction probe. The lower end of a side surface of the installation box is provided with a rule outlet. The beneficial effects of the invention lie in that the steel rule takes a single-chip microcomputer as a control core; the steel rule combines an optical fiber sensor, the Gray codes, a signal processing circuit, a voice prompt module, a key circuit and a display unit; the problems that a conventional steel tape is difficult for reading and is liable to cause the reading errors are analyzed; the sensor technology, the optical detection technology and the signal processing technology are integrated to achieve the automatic reading of the steel tape; a user just needs to listen to the voice reading or reads the value displayed by a display screen at any time, even at night; the steel rule is good in practicality.

Description

technical field [0001] The invention relates to the field of steel rulers, in particular to an intelligent steel ruler. Background technique [0002] Steel tape is one of the tools commonly used by various engineers and families in daily life. At present, when reading a steel tape during use, you need to look carefully to read the value, and it is difficult to read. Especially for older users, it is difficult to see the value on the ruler clearly due to the decline of eyesight, and it is easy to make a mistake. In view of the above situation, an intelligent steel ruler can be designed to solve the above problem. Contents of the invention [0003] The object of the present invention is to provide an intelligent steel ruler in order to solve the above problems. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a smart steel ruler, including a mounting box and a control box fixedly installed on the side of the mo...
