AUTOMATED COMPLEX FOR HYDROGRAPHIC AND GEOPHYSICAL WORKS IN AQUATORIES

The technical solution relates to the construction of combined instruments for hydrographic and geophysical surveys of water areas (seas, lakes, rivers, canals) and can be used to register and control a number of parameters when shooting routes for cables and pipelines, monitoring the bottom and underwater structures, shooting areas under drilling platforms and when searching for small objects.

Currently known systems 3-9, designed mainly for hydrographic surveying and including one or more blocks for measuring geophysical information.

The traditional components of such systems are (see, for example, 4, 9) a side-scan sonar (HBO), an echo sounder (EL) and a seismic-acoustic profilograph (SAP), as well as equipment for geodetic reference of observation points, for example, a sonar or satellite navigation system.

Hydrographic complexes 3-6 are also known, which provide geophysical (mainly seismic) surveys of water areas. Such systems (ship navigation systems for

G 01 V 1/38, G 05 D 27/00

marine seismic work, which can be considered using the 3U analogue as a rule, includes receivers of satellite navigation systems (NS), gyrocompass, reckoning devices (logs), echo sounders connected to a computing device (computer), printer and / or plotter and are intended for navigation and hydrographic support for marine seismic works. The disadvantage of such systems 3 is the limited application in complex geophysical surveys due to the impossibility of registering a sufficiently complete set of geophysical parameters. Existing navigation and geophysical complexes 2-4 are usually very complex, expensive and have a low level of standardization (unification) of external devices, which, due to the difference in operation principles and data output formats, complicates the management and pairing of individual devices, which creates certain difficulties when their use for the correct comprehensive studies of water areas.

These shortcomings can be partially eliminated with the modular principle of constructing a system (complex) with the unification of equipment and software 1.2.

So, the well-known complex of equipment 2 contains a HBO module, an SAP module, an EL module and a navigation system (NS) module, each of these modules including a measurement unit (BI) connected to a processing and recording unit (BOR), and the outputs of the HBO modules , SAP, EL and NS are connected to the output of the operational control information block (SIDE). Complex 2, like other analogues 3 - 9, has an insufficient level of module unification; complex 2 lacks synchronous indication and registration in a single data format.

Known multifunctional technological complex 1, adopted as a prototype and eliminating the disadvantages of analogue 2, which contains the HBO module, SAP module, EL module and the NS module, each of the HBO, SAP, EL and NS modules includes a BI connected to the BOR, and the outputs of the HBO , SAP, EL and NS are connected to the SIDE. In addition, complex 1 additionally includes a synchronous display and registration unit (BSIR) in a single data format and a switch of operating modes (RRC), while the outputs of the BOR modules of HBO, SAP, EL and NS are connected to the inputs of the BOKI and BSIR. In essence, complex 1 is a collection of meters and one (or several) automated workplaces of the hydrograph operator.

Complex 1 in each of the HBO, SAP, EL and NS modules has its own control computer (HC) and its own graphical and magnetic recording units, which is due to the possibility of separate (autonomous) use of the modules depending on the tasks being solved.

However, duplication of these blocks in complex 1 is not justified enough, since the blocks of HC, graphic and magnetic recording can be performed on the basis of one (common to all modules) HC, for example, on the basis of one (or two or three) personal computers. In addition, in some cases, the study of water areas requires expanding the set of both hydrographic and geophysical measured parameters, ensuring their synergy and increasing the reliability of the data.

The essence of the proposed technical solution lies in the creation of such an automated complex for research in water areas, which would, while maintaining the advantages of prototype 1 (providing synchronous indication of the processing of the shooting data), realize its adequate, but more optimal in composition

a design that provides a comprehensive, if possible complete and reliable survey of water areas based on a combination of both hydrographic and geophysical parameters. By implementing its purpose, the complex is close to complex (integral) complexes of 1.4, but its structure is simpler, more rational, more compact and cheaper due to the use of a single HC for all measuring modules.

The main technical result of the proposed complex is to increase reliability due to a rational design and reduce the composition of the equipment, to increase functionality by expanding the totality of measurements of two groups of parameters (hydrographic and geophysical), as well as to achieve optimal ergonomic properties of the complex due to the implementation of automated workplace (AWP) of the operator. In addition, unlike analogs and prototype 1, the complex allows you to display the results of measuring the parameters of a given area of the water area in a given scale and / or in a given coordinate system (coordinate area grid): rectangular, geodesic with various parameters of the earth's ellipsoid, etc. At the same time, an additional advantage of the proposed complex is the presence of an a priori database (BAA) and a planning unit (BPS), which allow to increase the accuracy of shooting the water area.

The technical result is achieved as follows.

An automated complex for hydrographic and geophysical work in water areas, characterized by the fact that it contains a block of hydrographic sensors (BIG), a block of geophysical sensors (BGEO) and a module of the satellite navigation system (MSNS) connected via interfaces to the operator's automated workstation (AWS).

A distinctive feature of the complex is that it contains a combination of two groups of sensors: BGID includes a group of hydrographic sensors (DHID), and BSEO includes a group of geophysical sensors (DHEO).

The main difference of the proposed automated complex for hydrographic and geophysical work in water areas is that the operator’s workstation includes a control computer (HC), an a priori database (BAA), a planning, monitoring and evaluation unit (BPC), a mode switch (RRC), a unit operational control information (BOKI), a synchronous display and registration unit (BSIR), a plotter of digital maps (GIC), an information storage device (NI), a coordinate system selection unit (BVC) and a scale selection unit (BVM), while interface odes BGID, BGEO and MSNS are connected to the inputs of the workstation, which are information inputs of the HC, the first, second and third control outputs-inputs of the HC are connected respectively to the inputs-outputs of the BAA, BPCO and KRP, the fourth and fifth outputs of the HC are connected respectively to the inputs of the BVK and BVM , the sixth and seventh HC outputs are connected respectively to the first inputs of the HCC and NI, the outputs of the BVK and BVM are connected to the inputs of the RCC, the outputs of the RRC are connected to the inputs of the BOC and BSIR, the output of the BOC and the first output of the BSIR are connected to the second and third inputs of the FCC, and the second output BSIR is connected to the second th input NI.

The complex is also distinguished by the fact that in specific cases of the BHID implementation, it contains a group of hydrographic sensors DGID, including a sonar module, a side-scan sonar module, a seismic profilograph module, a sound speed sensor, a system for measuring pitch parameters, as well as other sensors, for example, gyrocompass number gauges and lag.

in various specific cases, the difference of the complex is that the BSEO contains a group of geophysical sensors of the DHEO, including a magnetometer module, a gravimeter module, as well as other geophysical sensors, for example, an electrical exploration module, seismic survey module or a water pollution control system.

The complex is also different in that the ICSU is made in the form of a module of the differential satellite navigation system "NAVSTAR and / or" GLONASS.

Particular cases of the complex execution are that the standard computing units or a personal computer are used as the blocks making up the workstation, and the plotter is used as a fcc for constructing digital and / or geophysical maps at a given scale and in a given coordinate system.

The drawing shows a general diagram of the design of an automated complex for hydrographic and geophysical work in water areas.

The complex contains BHID 1, BGEO 2, ICS 3 and AWP 4 operators. BHID 1 includes a group of sensors DGID 5, and BGEO 2 a group of sensors DGEO 6. AWP 4 includes HC 7, BAA 8, BPOK 9, KRYU, BOKI 11, BSIR 12, FCC 13, NI 14, BVK 15 and BVM 16.

The complex works as follows.

The signals from the outputs of the sensors DGID 5 block BHID 1 hydrographic sensors, the signals from the outputs of the geophysical sensors DGEO 6 block BGEO 2, as well as the signals from the output module MSNS 3 through interface communication are fed to the inputs of the AWP 4 operator, which are information inputs of the control computer UV 7, equipped appropriate software. At the same time, BHID 1 contains a group of hydrographic sensors DGID 5, which includes an EL module (for example, grade NELZh1 g6

4M), a SAP module, a sound speed sensor (for example, an OLD-1 probe), a system of pitch parameters meters (SIPK), as well as other number gauges (GKU-2 or AMUR-ZM direction indicators, IEL-1 or LI2 speed meters -1). The group of geophysical sensors ДГЕО 6 includes a magnetometer module, a gravimeter module, and may also contain other sensors, for example, an electrical prospecting module and / or a water pollution control system (similar to that used in 2). As MCHC 3, the differential satellite module of the NAVSTAR and / or GLONASS systems can be used (for example, Trimble, Briz-K equipment, SNA differential correction receiver MK II Racal). As AWP 4, one or two personal computers (for example, Pentium-VOOEFCPGA models) with printers (such as LBR800) can be used, and as HCC 13, a plotter for building electronic digital cards (for example, Mutoh RJ-800C brand) . In AWP 4, synchronous processing of information received from BGID 1, BGEO 2, and ICSU 3 is performed: time reference, generation of files of measured hydrographic and geophysical parameters and coordinates of observation points. Monitoring, indication and data recording is carried out in the BOKI 11, BSIR 12, FCC 13 blocks, depending on the operating mode determined by the RRC 10 (by analogy with 1, 2). In this case, BOKI 11 is a visual observation screen (personal computer monitor) of the individual measured parameters, BSIR 12 carries out synchronous indication and registration in a single time. The block of dietary supplements 8 forms a database of a priori data for the survey area of the water area with the presentation of a preliminary survey plan from BPCS 9 to BOKI 11 by control signals of HC 7 received through the RRC 10, while the BPC 9 monitors the implementation of the survey plan and data evaluation

(quality of the tack survey) for reliability with the assignment of the corresponding attribute. Blocks BVK 15 and BVM 16 allow you to register and display areal surveys in a given coordinate system and in a given (required) scale, providing conversion of various coordinate systems and scaling of the resulting digital maps generated by FCC 13. NI 14 accumulates a set of synchronous measurement data for subsequent processing (post-processing and cameral processing). Thus, the complex collects, processes, and documents on technical (material) media the totality of navigational-hydrographic and geophysical information obtained when shooting the water area specified by the program, while data processing is carried out directly in the work area with an assessment of the quality of the survey and planning for repeated measurements. NI 14 with a set of data files and digital maps generated by the HCC allows final processing of the survey results in cameral processing using a unit identical to AWP 4.
