Description

A POSITION DETERMINATION MECHANISM

TECHNICAL FIELD

The present invention relates to a test mechanism which can measure whether persons are particularly suitable to work at height by means of the change in physical data of the person and the position.

PRIOR ART

In the present art, technical digital cranio-corpo-graphy or computerized ultrasound cranio- corpo-graphy tests are applied as the test of working at height. The system is in the form of a measurement unit, a head-guard with marker, shoulder markers, belted connection adaptor and computer. Head-guard and shoulder markers are put on and the belt is attached. For the stand test, the patient is requested to stand for one minute and close his/her eyes. For more precise testing, the arms are stretched out forward and recording can be realized. For the step test, the patient is requested to wait for one minute. The system realizes three- dimensional recording by means of ultrasound technology. However, this test cannot measure the behavior of the person together with physiological changes when said person is really at height.

As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

In this detailed description, the subject matter height test mechanism (10), which can make suitability measurement of the personal physical data and the position of the person to be tested during the test in the subject of testing the suitability of the person for working at height, is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

A height test mechanism (10) referred to Figure 1 essentially comprises a walking area (20) on which the person to be tested walks, at least one fan (21) positioned in the vicinity of said walking area (20), a measurement cloth (22) put on by the person to be tested, and a VR heading (23) put on the head of the person for providing virtual reality. There are at least two markers (24) on the measurement cloth (22). There is at least one marker (24) on the VR heading (23) and there is an orientation sensor (25) which senses the movement of the VR heading (23). The orientation sensor (25) can comprise sensors like acceleration-meter and gyroscope. At least one optic sensor (26) is positioned which senses the position of markers

(24).

On the person to be tested, preferably there is at least one physiological parameter meter

(30) positioned at suitable positions. Said physiological parameter meter (30) comprises at least one pulse meter (31), at least one blood pressure meter (33) and at least one temperature sensor (32). Preferably in alternative applications, sensors like saccharometer, etc. can also be used as the physiological parameter meter. The temperature sensor (32) determines the changes in body temperature of the person to be tested and the pulse meter

(31) determines the changes in heart pulse of the person to be tested and the blood pressure meter (33) determines the changes in blood pressure of the person to be tested. There is a measurement center (40) whereto said pulse meter (31), said blood pressure meter (33) and said temperature sensor (32) are connected. Said measurement center (40) comprises a data processing unit (41) to which the data, determined on the person to be tested, is transferred by the orientation sensor (25), the optic sensor (26), the pulse meter (31), the blood pressure meter (33) and the temperature sensor (32). In the data processing unit (41), the following is predefined: the temperature value range as standard or with maximum tolerance, heart pulse value range, heart pulse number which shall occur during a specific duration, the blood pressure which shall normally occur and the coordinate value ranges which shall occur as standard for the markers (24) on the walking area (20). The data processing unit (41) evaluates and measures the data detected by the orientation sensor

(25), the optic sensor (26), the pulse meter (31), the blood pressure meter (33) and the temperature sensor (32) within the predefined value ranges and presents the result as visual and/or written output by means of a user interface (43). The data processing unit (41) provides formation of a VR medium (virtual reality medium), where imaging can be realized for 360°, at VR eyeglass. Said VR device can operate in an independent manner or can be operated by means of software through the data processing unit (41). The data processing unit (41) simulates and changes the image provided on the VR eyeglass (23) on the screen so as to be equivalent to the image in real life according to the movement changes received from the software orientation sensor (25) existing thereon. This can be also realized by the VR device in an independent manner.

In an application of the present invention, the person, whereon the test for suitability for working at height will be realized, puts on the measurement cloth (22) and VR heading (23) and said person comes to the walking area reference point (20). At least one optic sensor (26) is positioned so as to view the walking area (20) from the opposite side. There are at least two markers (24) on said measurement cloth (22). Preferably marker (24) additions can be realized to the different regions of the cloth. The image of the medium where measurement will be realized on the VR heading (23) screen is given in a three-dimensional form. When the person who is to be tested turns his/her head rightward-leftward or downward-upward, the orientation sensor (25) transfers this to the data processing unit (41) and the data processing unit (41) provides displaying of the image, provided on the VR heading (23) screen, in a manner suitable to the change in the orientation and position.

The walking area (20) is preferably designed in a compliant manner to the medium to be tested. For instance, if the person to be tested will work on a metal frame with height of 100 meters or will work in a lift, the walking area (20) is designed in suitable dimensions by taking into consideration the flexibilities at 100 meters height and even the swings which result from the wind. Moreover, the wind blow, which may occur during working of the person to be tested, is simulated by means of said fan (21). As the person to be tested watches the simulation images and walks on the walking area (20), the coordinate/position changes of the markers (24) provided on the VR heading (23) is detected with the help of the optic sensor (26) and is transferred to the data processing unit (41). In a similar manner, the pulse meter (31), the temperature sensor (32) and the blood pressure meter (33) transfer the data, received simultaneously from the person to be tested, to the data processing unit (41). The data processing unit (41) compares the obtained coordinate/position and measurement information with the defined values and makes the analysis whether said information is within the determined value ranges and transfers the result to the user interface (43). If the marker (24) position and the pulse meter (31), the temperature sensor (32) and the blood pressure mater (33) results are outside the predefined value ranges in the data processing unit (41), the person to be tested cannot pass the test of working at height and if said results are inside the predefined value ranges, the person to be tested passes the test of working at height.

The data processing unit (41) determines the movement of the person to be tested within this time interval by means of the sequential images received from the optic sensor (26) within specific time intervals. At each image taken by the optic sensor (26), the position of the person to be tested can be monitored instantaneously. Markers (24) are visual elements formed by transverse colors and whose dimensions and positions are predetermined. Pluralities of alternative image processing methods can be used in determination of the positions of markers (24) and in determination of the position of the person to be tested.

Preferably camera is used as the optic sensor (26). In an application of the present invention, as the optic sensor (26), a camera which can realize depth measurement is used. By means of the camera which can realize depth measurement, measurement with sensitivity under centimeter can be realized. In more critical applications, thermal cameras can also be used optionally and/or as the second camera. In another alternative application, at least one optic sensor (26) with infrared characteristic is used.

The data processing unit (41) can evaluate the data received and can provide displaying of the result continuously during the test duration through the user interface (43). Preferably the data processing unit (41) can also evaluate a predetermined time slice or can realize evaluation within predetermined intervals and can transfer the result to the user interface (43).

By means of the usage of the subject matter height test mechanism (10), the suitability of the person to be tested for the work branches where working shall be realized at height can be measured and reported in an automatic and objective manner. Moreover, even if the person to be tested shows instantaneous resistance along the walking area (20), the probable risks can also be foreseen by means of monitoring the physical changes like getting excited of the person, thanks to measuring of heart pulse, blood pressure and body temperature.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
