Problems solved by technology

However, due to the distance between the conductors, the tape measure will suffer errors when measuring in real time
In addition, the disadvantage of the tape measure is that the measured length has to be recorded manually since the liquid crystal display (LCD) can only display the length and has no storage device

Embodiment Construction

[0048] Embodiments of the present invention will be described in detail below with reference to the drawings. It should be noted that numbers are assigned to constituent elements in each drawing, and the same reference numerals are used as much as possible for the same constituent elements even if they are shown in different drawings. Also, in describing the embodiments, when it is judged that the detailed description of the corresponding well-known configuration or function hinders the understanding of the present invention, the detailed description thereof is omitted.

[0049]In addition, terms such as first, second, A, B, (a), and (b) can be used in describing the constituent elements of the embodiment. The above-mentioned terms are only used to distinguish this constituent element from other constituent elements, and do not limit the nature or order of the corresponding constituent elements through the terms. When it is stated that a constituent element is "connected", "c...

Abstract

A length measurement device comprises: a tape which is wound on a reel received in a case, one end of which is pulled out of the case so as to measure the length of an object, and which has a barcodeformed on one surface thereof; a first measurement unit for recognizing the barcode on the tape so as to generate a first measurement value of the length along which the tape is pulled out of the case; a second measurement unit for sensing a rotation angle of the reel so as to generate a second measurement value of the length along which the tape is pulled out of the case; and a control unit for making the first measurement value and the second measurement value mutually compensate for each other so as to convert same into the pulled-out length information of the tape.

Description

technical field [0001] The invention relates to a length measuring device and system. Background technique [0002] Generally speaking, a tape measure is formed in the form of a tape, the surface of which is marked with scales showing length, and is used to measure the amplitude or width of a certain space, or measure the size, length or width of a measured object. [0003] There are many kinds of tape measures, and a typical tape measure includes a ruler wound into a coil, a scale marked on the surface, and an inner space for storing the ruler and a casing for guiding the introduction and extraction of the ruler in the inner space, so that the user can pass Pull out the scaled ruler and read the scale near the end of the ruler and the main body that reaches the end of the object to measure the length of the object to be measured. The disadvantage of this type of tape measure is that the length of the measured object can only be determined visually and therefore takes a lon...
