No. 5), which is mainly used in repair and finishing work to perform measuring and / or cutting, drawing work, consisting of a body, a stationery holder, blades for sharpening a pencil, a measuring tape, a hook/needle, a measuring tape retainer, characterized in that the sharp side of the pencil sharpening blade is located at the bottom of the stationery holder, while the pencil sharpening blade has a gap between the axis of the stationery holder and the sharp part blades for sharpening a pencil.

The disadvantage of this device is the low speed measurement for data logging.

The closest is a measuring device (patent US7500322B2 published 2009-03-10) containing: a tape measure having a body containing a flexible tape, a holding block mounted on the body, a sharpening device mounted on the holding block; a locking block having a diagonal locking groove located within the locking block, a marking tool having a marking tip obtained in a diagonal locking groove in which the marking tool is positioned such that the marking tip abuts the flexible tape so that a mark can be made on the surface to be measured without removing the marking tool from the diagonal locking groove.

The disadvantage of the closest device is the low speed measurement for data logging.

Utility Model Disclosure

The technical result of this solution is to increase the measurement speed for data recording.

The technical result is achieved in a measuring tape device with automatic registration of measurement results, containing a housing, a measuring tape, a hook, a measuring tape clamp, and a screen of a reading computer unit is installed on the housing, and a reading computer unit, including a digital readout device and a computer, to which connected: a temperature sensor, a camera, a Wi-fi module and a laser sensor installed above the measuring tape in the direction of movement of the measuring tape, with the possibility of transmitting electronic data to the computer unit at the point where the laser touches the upper plate of the T-hook, for recording measurement readings.

The distinguishing features are:

a screen of a reading computer unit is installed on the case, which makes it possible to control the accuracy of the readings taken to increase the speed of measurement during data recording;

reading computer unit, which includes a digital reading device and a computer to which are connected: a temperature sensor, a camera, a Wi-fi module and a laser sensor, such a design solution allows the reading computer unit to additionally take into account measurement errors taking into account temperature sensor data and fixes a place with a camera measurements;

a Wi-fi module connected to a computer allows you to quickly transfer the received measurement information from the roulette computer to interested consumers;

a laser sensor installed above the measuring tape in the direction of the measuring tape movement, with the possibility of transmitting electronic data to the computer unit at the point where the laser touches the upper plate of the T-hook, for recording measurement readings, this design increases the measurement speed, here analog data is converted into digital and a measured indicator is set, excluding inaccuracies of the mechanical part.

Additionally, the claimed device allows:

eliminate the human factor - operator errors when fixing the measurement results;

increase the speed of ongoing research by automating the filling of the database on an electronic device (desktop computer, laptop, smartphone, etc.);

transfer measurements to an electronic device via a wireless interface.

A comparative analysis of the features of the claimed solution with the features of the prototype and analogues indicates that the claimed solution meets the criterion of "novelty".

In FIG. an isometric view of a measuring tape with automatic registration of measurement results is shown, including: 1 - body; 2 - measuring tape; 3 - T-shaped hook; 4 - measuring tape clamp; 5 - plate of the lower stop of the hook; 6 – the top plate of the hook for measuring the distance with a laser; 7 - screen of the reading computer unit; 8 - laser sensor; 9 - a reading computer unit that combines a digital reading device and a computer to which are connected: a temperature sensor, a camera, a Wi-fi module, a laser sensor; 10 – thrust surface of the body base; 11 - reading line of the reading device.

Implementation of the utility model

Measuring tape with automatic registration of measurement results contains a housing 1 inside, which is equipped with a measuring tape 2 with a T-shaped hook 3 on a spring. The measuring tape retainer 4 is also a measurement signal sensor. The digital readout device is a part of the reading computer unit 9. The holder of the exhaust end of the produced measuring tape 2 is a connecting axis that fastens the edge, which is round in shape, with fastening at the exhaust end of the produced measuring tape 2, which allows rotation by three hundred and sixty degrees relative to each other.

Before starting work, a workplace is equipped. Then the proposed device is connected to an external digital media via a wireless network. The reading computer unit 9 is turned on. At the beginning, the measuring tape is placed on the object being measured to measure the length, hooked with a T-shaped hook 3 by the plate of the lower stop of the hook 5 over the edge of the object, the tape is stretched to the opposite edge of the object being measured, pressed against the stop surface of the base of the body 10. It is clamped a measuring tape clamp 4, which is simultaneously a measurement signal sensor by a laser sensor 8, installed in the direction of measuring the length to the upper plate of the hook 6. The laser sensor 8 is configured to transmit data to the reading computer unit 9, where analog data is converted into digital. The indications of the length of the laser line of the laser sensor 8 are displayed on the screen 7. The used OADM 20I2441/S14C sensor allows obtaining data with an accuracy of 0.05 mm. [4]. The indicator, taking into account the digital data of the electronic roulette device along the reading line of the reading device 11 from the tape 2, is set with an accuracy of 0.1 mm. [1], this indicator is also displayed on screen 7. If the difference between the two readings is less than the set deviation, then the information received from the roulette is transmitted to external digital media using the Wi-fi module for further processing and transmission to interested consumers. If the difference between the two readings is greater than the set deviation, then the measurement along this line is repeated in order to eliminate technical errors. The data obtained in this way can significantly improve the speed of measurement and data processing.

The effectiveness of the proposed measuring tape lies in its ability to provide measurement speed, as well as increased measurement accuracy at high performance.
