Description

The utility model relates to the field of measuring technology and can be used to determine the exact coordinates of the relative position relative to each other of three specific points in space. The instrument can be used in the field of craniometry (including craniotrigonometry) and osteometry, as well as in other branches of science and industry, where trigonometric data are used. The development of the device makes it possible to speed up the process of recording measurement results, thus speeding up and streamlining the work of researchers.

Known "Electronic coordinate compass" (Patent for utility model No. RU 158775 U1. - Publ. 20.01.2016. Bull. No. 2), characterized in that "millimeter scales are supplemented with electronic ones, and an additional scale is introduced that allows you to determine the degree of remoteness of the position the third measuring leg, moving both horizontally and vertically, away from the other legs. " The proposed utility model "Coordinate compass with automatic registration of measurement results" differs from it by the presence of a wired connection, which allows the automatic transfer of the obtained metric data to an electronic medium (desktop computer, laptop, smartphone, etc.). The technical result for the preparation of the model is to increase the convenience and efficiency of measurement work, increase the speed of work.

A wired connection is simultaneously used to power all electronic readout units. Powered by the USB connector, the compass can operate indefinitely (independent of the capacity of rechargeable batteries or batteries).

During the development of the utility model "Coordinate compass with automatic registration of measurement results" the following specific task was set:

- increasing the efficiency of fixing the measurement results with the simultaneous elimination of the negative influence of the "human factor" (operator errors) by replacing the operation of filling tables on paper or electronic media manually with an automatic one;

Along the way, a number of auxiliary tasks were also solved:

- to provide convenience in handling the measuring device due to the implementation of all elements of the compass made of carbon fiber materials, which significantly reduces its weight and excludes corrosion of metal elements;

- prompt creation of documentation in digital form, ensuring its reliable and compact creation, prompt exchange of information between consumers.

An electronic coordinate compass was chosen as a prototype and analogue of the device under development (Patent for utility model No. RU 158775 U1. - Publ. 20.01.2016. Bull. No. 2, Russia). This model is characterized by the presence of three readout electronic devices with a small screen. It is practically the only improved modification of the coordinate compass, the design of which was originally proposed at the beginning of the 20th century by K.S. Merezhkovsky.

Together with this, the design has a complex disadvantage:

- it does not have a direct wire connection with an electronic carrier (desktop computer, laptop, smartphone), which makes the technique of registering metric results more laborious and slows down the progress of research work.

The solution to this problem is achieved by the fact that the electronic coordinate compass is supplied with a wired connection for transferring information to an electronic device, which can be a desktop computer, laptop, smartphone, etc. The recording of metric data is performed at the moment of pressing a button on the control panel, which, for convenience work, is located on the flexible part of the wired connection, which carries a USB connector for connection to an electronic device.

A similar (not identical) transmission is used in calipers from MITUTOYO (Japan) and Vogel-Germany. However, all products of these companies can only measure linear absolute dimensions.

The proposed compass allows you to simultaneously measure both absolute and relative sizes, determining the relative position of three points at once. In this case, all measurement values are positionally synchronized with each other and are simultaneously transmitted to an electronic device (desktop computer, laptop, smartphone, etc.). In addition, in the model "Coordinate compass with automatic registration of measurement results" the control panel carries a flexible part of the wired connection, which provides maximum convenience in data transfer.

New elements introduced into the design allow to streamline the process of measuring work and fixing results during craniometric and osteometric studies.

Figure 1 shows a diagram of the useful model "Coordinate compass with automatic registration of measurement results."

The device (figure 1) contains:

1 - measuring rod of the coordinate compass with a fixed leg;

2 - movable leg of the coordinate compass, moving in the horizontal plane;

3 - reading block with a screen, fixedly connected to the movable leg of the coordinate compass, moving in the horizontal plane;

4 - movable leg of the coordinate compass, moving in the horizontal and vertical planes;

5 - reading block with a screen, fixedly connected to the movable leg of the coordinate compass, moving in the horizontal and vertical planes and fixing the distance to the fixed leg of the coordinate compass;

6 - counting block with a screen that fixes the range of motion of the movable leg of the coordinate compass in the vertical direction;

7 - flexible wire connection between three reading blocks of the coordinate compass, equipped with a USB connector for connection with an electronic device;

8 - control panel for coordinate compass;

9 - electronic media (desktop computer, laptop, smartphone, etc.).

The movable leg of the coordinate compass, moving in the horizontal plane 2, is fixed on a bar with a fixed leg 1. The reading unit 3 is fixedly connected to the movable leg 2. A movable leg is also fixed on the bar of the coordinate compass, which can move both horizontally and vertically plane 4, equipped with two reading blocks, one of which (5) fixes the distance at which this leg is located from the fixed leg of the coordinate compass, the other (6) shows the distance between the end part of the leg 4 relative to the line formed by the end parts of the fixed leg 1 and movable leg 2. The device is equipped with a flexible cable with a USB connector 7, carrying a control panel of a simple design 8. Using the USB connector, the device is connected to an electronic device (desktop computer, laptop, smartphone, etc.) save information.

FIG. 2. shows the appearance of the device.

The device "Coordinate compass with automatic registration of measurement results" operates as follows:

After equipping the workplace, the model is connected to an electronic device, for example, a laptop, using a USB connector, on which a special program is turned on to work with the proposed device. The control panel of the device, which is located on the flexible part of the wire connection, is located at the workplace in such a way that access to it is not difficult, but, at the same time, it itself was not an obstacle to the implementation of metric work.

Before metric work, the data of all three scales are reset to zero by bringing the end part of all three measuring legs to one point and pressing the "zero" button on all three electronic units of the coordinate compass. The measurement is then carried out. For this, the measuring legs are fixed on the desired osteometric or craniometric points. The measurement result is reflected on the screens of three electronic blocks of the coordinate compass. Then the metric data is transferred to the electronic device. To do this, press the button of the control panel located on the flexible part of the wire.

At the same time, the obtained values can be checked both on the digital display of the reading blocks and on the computer screen. This eliminates operator errors when entering data into a computer and speeds up the process of entering data into a computer. In the future, the measurement cycle can be repeated an unlimited number of times.

It is important to pay attention to the fact that at the moment of transferring information to the electronic device, the measuring legs of the instrument continue to remain stationary. The data received in this way on an electronic carrier can immediately be subjected to analytical and statistical processing. This circumstance is the main advantage of the utility model.

In full compliance with the formula of this utility model, the applicants have made a prototype. Testing this sample showed the possibility of using the model in osteometric and craniometric works.

All three measurements are made using the standard method for the coordinate compass by bringing the end part of the measuring legs to the points between which you want to find the direct and projection distance. When all sizes are reflected on the screens of electronic reading devices, the received data is transferred to an electronic medium (desktop computer, laptop, smartphone, etc.) by pressing the button on the control panel. Information is transmitted to an electronic device using a wired connection, on the flexible part of which the mentioned control panel is located.

The utility model makes it possible to quickly record the results of metric work in the memory of an electronic device and make information available for statistical analysis almost immediately after measurements, and also opens up broad prospects for the formation of metric information databases.
