Description

The field of technology.

The present invention relates to measuring technique and can be used in the design and manufacture of oceanological multi-channel information-measuring systems and the development of new measuring channels.

State of the art

Analyzing the level of automation of oceanological experimental research in our country, we note the period of the 60-70s, when the most interesting were data collection and processing systems built similar to the SAMAS standard information-measuring systems created under the guidance of academician Nesterikhin Yu.E. They were widely used in various fields of experimental research automation due to the fact that they had a flexible, easily changing structure, well-developed software and could be quickly converted to a new experimental research program. Information-measuring systems based on the SAMAS standard are widely used in biology and medicine.

In the 70s - 80s, at the Special Design and Technology Bureau of the Marine Hydrophysical Institute of the Academy of Sciences of the Ukrainian SSR (SKTB MGI AS of the Ukrainian SSR) based on the analysis of the experimental problems of modern oceanology taking into account the level of available measuring equipment, means and methods of conducting experimental research in other areas of knowledge, comprehensively The problem of automating the collection and processing of experimental data for the entire spectrum of spatio-temporal variability of the parameters of the physical fields of the ocean has been solved. A design system for oceanological measuring complexes built on a modular basis was created, a basic structural scheme was developed for building modular measuring complexes of oceanological parameters on its basis. All the main directions of work are performed at a fundamentally new technical level and are protected by 8 copyright and 17 patents for inventions.

Sounding, towed, autonomous and special information-measuring complexes were created, their state tests were carried out, all devices were certified, mass-produced and introduced into the practice of oceanological research of institutions of various ministries and departments of our country.

A special place in the creation of modular information-measuring systems of oceanological parameters was occupied by the metrological support of the entire cycle of their development and certification. Certification work for all measuring channels developed at SKTB MHI was carried out jointly with the institutes of Gosstandart of the USSR.

The well-known "Sensing complex profile of the speed of currents, containing meters, switches, ADCs, modems, interface and control units, operational and programmable storage devices, and other elements of digital technology" [1].

The known device has a low speed of information transfer, complexity in operation and low reliability.

A device for marine research, containing two blocks of measuring channels with parameter sensors connected via modems to an electric channel in the form of a cable cable with a ship recorder [2]. Although this device eliminates most of the shortcomings of the previous one, it is also imperfect.

SUMMARY OF THE INVENTION

The introduction of satellite measuring systems, free-drifting surface buoys, free-drifting buoys for vertical sounding of profiles of hydrophysical parameters and measuring the velocity of currents at given horizons into practice of experimental ocean research has created a prerequisite for understanding the possibility of monitoring the marginal seas and large water areas of the World Ocean. The urgent issue was the need to develop a fundamentally new optical measuring channels and instruments that allow for in situ contact measurements at sub-satellite ranges and to determine the concentration of suspended matter and suspended organic matter in sea water.

Such optical measuring channels include television or IP cameras, which require the use of high-speed data channels (10-1000 Mbit / s).

The present invention solves the problem of creating conditions for the development, manufacture, laboratory and full-scale testing of new optical measuring channels in situ to identify and record the amount of suspended matter and suspended organic matter in sea water.

Conducting laboratory and field tests of these measuring channels requires the use of high-speed data transmission channels (10-1000 Mbit / s). Testing at depths of up to several thousand meters requires the use of high-speed data channels of the appropriate length, which is ensured by the use of fiber-optic communication lines.

The main element of the created hydro-optical-chemical complex is its functional diagram, which should:

to ensure integration of the currently existing hydrophysical measuring channels;

to provide laboratory and field tests of newly created optical measuring channels together with other hydrophysical measuring channels, in order to study the effect of variability of the boundary hydrophysical conditions in the experimental area on their metrological characteristics;

contain in its composition the electric and fiber-optic communication lines combined in a cable cable.

This goal is achieved by the fact that in the known device for marine research, containing a block of hydrophysical measuring channels, a central controller, first and second modems of an electric communication line, a cable cable with electric and fiber-optic communication lines, a rotating electrical transition, an electric winch, working operator’s position, block of optical measuring channels, a block of normalizing controllers has been introduced, with each hydrophysical measuring channel through a corresponding normalizing con the roller is connected to the central controller, in addition, the first and second multi-input optical modems and a rotating optical transition are introduced, each optical measuring channel being connected to the corresponding input of the first multi-input optical modem connected via a fiber-optic cable-cable communication line to the rotating optical transition, connected to the second multi-input optical modem connected to the operator’s workstation.

Block normalizing controllers 2 contains normalizing controllers for hydrophysical measuring channels with numbers 1-6 and for standby hydrophysical channels.

The hydrophysical measuring channels are connected using normalizing controllers. Each normalizing controller receives measurement information from the corresponding measuring channel by its data transfer protocol and processes it into a unified data word read by the central controller 3.

The central controller 3 reads the unified data words from the normalizing controllers and generates measurement data packets from them, which are sent to the workstation through the first modem of the electric communication line 4, the electric communication line of the cable 5, the rotating electrical transition 6, and the second modem of the electric communication line 8 operator 9.

The block of optical measuring channels 10 contains optical measuring channels (with serial numbers 1 to 2 and redundant channels) requiring the use of high-speed data transfer (10-1000 Mbit / s).

Information from the optical measuring channels through the first multi-input optical modem 11 and via the fiber-optic communication line of the cable cable 5, through the rotating optical transition 12, is transmitted to the second multi-input optical modem 13 and then sent to the operator’s workstation 9.

A rotating electrical transition 6 and a rotating optical transition 12 are rotated by an electric winch 7.

Characteristics of the block normalizing controllers:

Interfaces of connected measuring channels: RS232, 0-5V 16 bit Number of Normalizing Controllers: up to 32 Built-in Clock Data Format: year, month, day, hour, minutes, seconds, milliseconds Polling time one normalizing controller: no more than 1 ms The output data word of the normalizing controller: 8 bytes
