PR is ntrolle measuring technique, in particular to the field of optical devices for remote non-contact inspection and measurement of the spatial position of the parts of the extended object during its deformation.

It can be used as a measuring device in the engineering, construction, aircraft and shipbuilding.

There are various electric and hydraulic (for example: Hydrostatic leveling. Information sheet documentation. Khabarovsk STIC, 1990) prohibere, which can control the deformation of interest to only a small extent.

Known optical prohibere (for example: a Device for measuring deformation transport floating docks. A. C. 249720. IPC G 01 L, B N 25, 1969 ), working at a considerable distance.

Known optical programer (and.with. 346573, MKI G 01 B 11/16, BI N 23, 1972), which allows you to record the deformation of the dock with a length up to several hundred meters. This programer on the totality of symptoms is the closest to the invention the device and is taken as a prototype. It contains unit basic directions in the form of consecutive eyepiece, lens and prism block, forming two optical channel, and installed in coach (on the bow and stern dock), and the unit base direction between the controlled points (control station). The generator creates long optical measuring base in the form of two sighting lines. The reference values of deflection (bow and stern relative to the control) is visually observed simultaneously in the field of view eyepiece scales of both the target goals, shifting relative to each other.

Optical programer has low accuracy due to the influence of the observation conditions and the subjectivity of visual measurements, it is not possible to control deformation of the nose and hull separately and use programer as sensor alarms and automatic alignment of the dock. This is caused by the presence of prohibere only visual information about the deflection and the absence of electrical signals associated with the deformation values for controlled points.

Another disadvantage of the considered optical prohibere is the following. Programer on the dock is designed to control the deformation of the dock caused by mechanical loads when setting the ship into the dock. If mechanical strain reaches a critical value, it may nastupali, due to the temperature difference between underwater and above-water part of the dock. Temperature deformation does not threaten the strength of the dock and should not be taken into account when measuring deflection. Long-term practice of exploitation docks showed that the temperature of the dock htwith a sufficient degree of accuracy is determined by the dependence of

htk(tin-tp)

where tpthe temperature of the upper part of the deck;

tinwater temperature;

K coefficient of thermal deformation of the dock, determined by the design of the dock.

The above optical programer registers only the total deflection (mechanical and thermal). This is caused by the lack of prohibere electrical signals associated with temperature situation during the measurement of the deformation and failure of automatic calculation and introduction of amendments in the measurement visual measurement.

Thus, the disadvantage of the considered optical prohibere is the inability to achieve a technical result, which consists in receiving the electrical signals associated with the deformation values for controlled points and with temperature situation at the time and the ranks impede the achievement of the desired technical result when using the considered optical prohibere are no sensors information about the offset of the target goals with respect to the optical measuring base, the sensors on the temperature situation during deformation measurements and device for the automatic calculation of deflection and the introduction to the measurement result of the amendments to thermal deformation.

The purpose of the invention to create prohibere, allowing to improve the accuracy of the measurements and has the generic capabilities to control deformation of the bow and stern separately, to use programer as sensor alarms and automatic alignment of the dock and register only the mechanical component of the trough.

This technical result in the implementation of the invention is achieved in that the optical programer contains consistently located lens, prismatic block, forming two optical channel, and target goals established in each of the channels; each of the target goals made in the form of emitter and programer provided with two control devices emitter, cookham power receiver, amplifier, switch, temperature sensor, analog-to-digital Converter (ADC), programmable controller, keyboard controller and display device; and electrical input KOI connected to the output of the power supply of the receiver, the output KOI to the input of the amplifier, the amplifier output to the corresponding input switch, output switch with the input of the ADC, the ADC output to the corresponding input of the programmable controller, the other input of the switch with the output of the temperature sensor, the input of each emitter is connected to the output of the corresponding device control unit, the inputs of the control devices with the corresponding output of the programmable controller, the other input of the programmable controller is connected to the output of the keyboard controller, and the other output of the programmable controller to the input of the indicator device.

A programmable controller is designed as a device I / o (UVV), CPU and random access memory (RAM), UVV connected to the Central processor, which is connected with a RAM, and the inputs and outputs of the programmable controller are the corresponding inputs and outputs UVV.

Set out the essential features of the invention allows to achieve the desired technical result and goal. The presence KOI allows you to create the optical channels of the measuring base, defined by the center KPO, performance target goals in the form of emitters to generate electrical signals when they are offsets relative to the base, which is proportional to the displacement and can be used to accurately measure the deformation of the bow and stern dock separately, to control alarms and automatic alignment of the dock. The presence of a temperature sensor allows you to get information about the temperature of the situation during the measurement of deformations. Programmable controller allows to calculate the deflection from the measured deformation of the bow and stern dock and register only the mechanical component of deflection, without the s compared to the visual method.
