Description

PIK is intended for the collection, processing and storage of geophysical data measured (using the same PIK), converted to the required format and arranged in arrays for future use, in particular for processing electromagnetic sounding data during geological exploration. PIK is used both for land and marine measuring installations, in particular, for conducting geophysical studies using the differential-normalized method of electrical exploration (DNME), as well as the electrical exploration method to study the geoelectric and polarization properties of the earth's crust. PIC is designed to process land and sea data in automatic mode.

The invention is known "Device for collecting, processing and packet transmission of the results of measuring the parameters of the physical environment", patent RU No. 2080653, publ. 05/27/1997, IPC G06F 17/40, containing a control computer complex with address-information and command line and measuring sensors. The device allows for operation in maintenance-free mode as one of the peripheral devices of the communication network to provide packet transmission of reliable, slightly redundant and grouped by certain signs information about the parameters of the studied physical environment. However, it does not provide processing of land and sea data of measuring devices in automatic mode, the problem of linking the observation system by calculating the coordinates of each element of this system is not solved, the required degree of noise immunity for a given time range is not achieved.

Closest to the claimed device is the invention "Geophysical system for collecting and processing information", patent RU No. 2091820, publ. 09/27/1997, IPC G01V 3/08, G01V 1/22, containing a data collection program, a data processing and storage unit, and a data processing unit combined with a control unit. The system provides the collection and processing of geophysical information, in particular, the measured, recorded and processed electrical and magnetic components of the electromagnetic field, when studying the geodynamic processes taking place in the earth's crust, using electrical exploration methods. However, the system is not compact because includes intermediate data processing points and a data transmission system in a single point. This reduces the number of signals simultaneously processed by the station, and also does not provide the universality of data processing in full, regardless of the type of measuring installations.

At present, during the collection, storage and processing of electromagnetic sounding data, it is required to process field material in automatic mode, as well as to ensure the storage of new information in specified formats for their further convenient use and verification of intermediate results. In addition, the system should ensure coordination of interactions of the created arrays of information that are transmitted, stored and further processed in comparable file formats. This requires arrays of primary and secondary data, in particular the current arrays of measured data, to represent in the format of relational files or in the format of internal binary files. So, links to binary files must be placed in the format of relational files, to ensure the collection and storage of all primary field information.

The volumes of source data arrays increased significantly, so the number of points recorded during the field season began to number in the thousands, which complicates their collection and further transmission and processing at intermediate stages.

It is also required to carry out initial analysis and editing of the primary field material (signal arrays) in order to remove those collected measurement results during sounding where there is a known high level of noise.

For more reliable collection, storage and processing of hydrographic data and topographic survey data, it is necessary to coordinate the observation system in space by calculating the coordinates of each element of this system (PIK), and these coordinates must be stored in tables in a relational database (DB) containing data, associated with electromagnetic sounding, and the data should subsequently be transmitted in the form of data packets, each of which constitutes an information unit.

In addition, in the complex (PIK), it is required to remove the trend at each time delay (during measurements) arising under the influence of telluric currents, zero drift of amplifiers, changes in the electrode potentials, and use an iterative approach to minimize the effect of emissions and failures, which can provide, for example, through the use of high-pass filtering of signals in the transmission of data packets.

Thus, it is necessary to solve the problem of removing industrial periodic interference, which is suppressed by using a differentiating filter, as well as the problem of stability of measurements, which is ensured by applying a sequence of collection and processing of information arrays using robust statistics methods.

Due to this, a high degree of noise immunity is achieved in the PIK complex, which is confirmed by the stability of the results and reproducibility of control observations with an accuracy of less than 1% for a given time range.

Thus, the proposed technical solution of the software-measuring complex (PIC) ensures the achievement of the following technical result:

- an increase in the volume of measured data arrays for each time measurement cycle presented in operational units or primary data, as indicated in the ADC reports, for batch transmission of data in the required format suitable for subsequent conversion operations;

- an increase in the number of simultaneously processed data arrays (complex performance);

- ensuring PIK universality for different geophysical sounding schemes, i.e. for different dipole installations of a geophysical measuring system (DU GIS), in particular:

- for surface dipole installations of the line-line type (two receiving lines);

- for ground-based dipole installations of the loop - line type (receiving line - generator loop);

- for marine dipole installations with multiple receiving lines;

- and also, without significant changes in the PIC, it is possible to process the data loop - loop (receiving loop - generator loop).

The claimed technical result is ensured by the fact that the software-measuring complex (PIK) contains a geophysical measuring system (GIS) (1) associated with data processing units (2), (3), one of which is combined with a storage unit for measured data (4) and the second with a control unit (CU), which is essentially a source data processing unit (5), and equipped with software.

and the GIS unit (1) also includes

- an ADC (12) of the delta-sigma type ADC with a large dynamic range for recording electromagnetic sounding data, and external devices (13) (GPS, multimeter, echo sounder, depth sensors, etc.), providing additional information about the measuring system, jointly representing a control unit (5) equipped with special software,

- information storage device (UNI) (14)

- and information processing device (UOI) (15), including:

- editing module (16) equipped with special software (software)

- and an information signal processing module (3) (data processing module).

The PIK additionally contains a start-up board (17), by means of which the operation of the start-up block (19) is synchronized with the work of the storage unit of the current array of measurement data (BHTM ID) (18), and the tracking board (20), which provides the unit through the binding module (8) GIS (1) linking DUT (6), in particular dipole installation (DU), to maps and editing an array of operating units in binary file format in the UNI (14), while ensuring the stability of obtaining results by applying robust statistics methods, while launch (17) includes - and including them in work in a given sequence

and the escort board (20) includes:

- and a unit for viewing, editing and converting (25) for comparing ordinary and control observations and building plans - schedules of DNP, and

the launch board (17) begins to work at the initial stage of the PIK and continues to work in parallel with the working board (7) when removing and automatically processing the research information of the GIS unit (1). In particular, the GIS unit is configured to connect the DUT (6) in the form of a ground installation such as a line-to-line dipole or a loop-to-line DUT or to connect the DUT in the form of a dipole marine DUT with several receiving lines. In addition, the module for binding (8) of the dipole installation to the terrain of the GIS block (1) includes, for example, raster maps, vector maps and road tracks. The switching channel 2 (11c) of the processed UOI (15) information signals and the connecting ADC (12) with the UNI (14) is equipped with communication branches of this channel 2 (11c) depending on the number of sectors (depending on the number of channels used in the DUT) of the processing module (5) information signals, for example, the processing module (5) of information signals includes the following sectors:

- sector interference elimination (26) in each array of information signals on interference with the provision of monitoring the effectiveness of eliminating interference in frequency recorded in the format of relational files of type A _k ,

- compression sector of arrays (27) of operational units within time windows with a logarithmic step,

- sector of the formation of the total arrays of operating units (31), recorded in the format of relational files that reflect the resulting transient curves. At the same time, for example, the interference cancellation sector (26) in each array of information signals provides the elimination of interference from emissions arising from lightning discharges and voltage surges in power lines, industrial periodic interference and high-frequency noise; the sector of formation of an array of operational units (29) records the measurement result in the format of relational files of type B _k under the condition that the PIC operates on ground-based DUTs of the line-line type or DUTs of the type loop-line; or the sector of formation of an array of operational units (29) records the measurement result in the format of relational files of type B _k under the condition that the PIK operates on marine type remote control with several receiving lines. In addition, arrays of operating units through the branches of the switching channel 2 (11B) are transmitted as follows:

- an array of operational units in the format of relational files of type A _k - to the interference elimination sector (26) and then to the sector of formation of the array of operational units (29) for marine remote control or ground-based remote control of the AOI processing module (15);

- an array of operating units in the format of relational files of type C _k - to the sector of reprocessing compressed arrays of operating units (30) and then to the sector of formation of the resulting arrays of operational units (31) of the processing unit of the OOI (15).

Also, in particular, the hydrographic information editing unit (24) includes the following modules:

- module for eliminating errors and failures in hydrographic data (32), combining them and bringing them to a single time grid of electromagnetic soundings;

- a module for determining the boundaries of intervals (33) over which spatial averaging of electromagnetic sounding data and hydrographic information is performed;

- a module for calculating the apparent electrical resistivity (34) for a moving measuring system with one generator line and several receiving lines;

- a module for comparing the results of electromagnetic observations and hydrographic data (35) for double passes along the same profile.

- In addition, file and relational arrays are allocated in operating unit arrays (source data arrays) of the information storage device (UNI) (14) in the storage unit of the current measurement data array (BHTM ID) (18). In this case, for example, relational arrays (36) of operational units in the source data array contain:

- an array of initial characteristics of the work: customer, job number, work area, measurement profile;

- an array of characteristics of external devices: type, number of operators, type of switching communications with them;

- an array of characteristics of the measuring equipment: type of measuring devices, calibration coefficients and corrections;

- an array of characteristics of each picket from A to H for a specific type of remote control - the coordinates of the elements of the measuring system at the recording point of electromagnetic sounding (picket) or the coordinates of the anchor point of the observation point;

- an array of characteristics of observation numbers from a to h - records of unique observation numbers in each picket, associated with an array of initial characteristics of the work for an array of information on the binding of observations;

- an array of characteristics of files with source information that are stored in the file array (37) of the source data, contain a path along which they will be saved in the file format in the file storage unit of the source data.

In addition, file arrays (37) of operating units in the source data storage module (4) contain:

- an array of primary information on relational arrays of operating units;

- an array of information about transients, which is an array of primary data from the ADC;

- an array of information on the binding of observations;

- an array of information of the results of processing primary information;

- an array of processing results - calculation of curves (functions) of differential-normalized parameters (DNP).

The scheme of the software-measuring complex (PIK) is explained, but its work is not limited to the following drawings.

The system operates as follows.

With the development of a marine modification of measuring systems and a significant increase in the volume of measured values during geological work, when the number of points recorded in the field season began to number in the thousands, it became necessary to create a new relational file structure. Along with it remains the file structure necessary for storing significant volumes of primary (field) information - primary data of electromagnetic soundings, data from external devices (GPS, echo sounder, depth sensors, etc.). Processing of such a volume of data should be carried out automatically and, therefore, the storage of initial information and coordination of the work of blocks and modules of such a new software-measuring system should be carried out. Her work was organized on the Microsoft SQL Server platform and combined in a storage unit for the current array of measurement data (BHTM ID) (18), which consists of two types of input data modules - file and relational, containing memory elements with an array of operating units located in the information storage device (UNI) (14), i.e. a relational array of source information and a file array of source information. Another file array is also located in the measured data storage module (4) of the UNI (14).

There are modifications of the complex for ground-based sounding by a dipole setup, a setup with two receiving lines and a generator loop, as well as for marine dipole soundings.

The operation of PICs for land and offshore measurement facilities should be described separately.

The collection and processing of data in the PIK for ground-based installations of the line - line and loop - line differ slightly, therefore, one description is given for them.

All blocks of the software-measuring complex are launched from the launch board (17) with embedded software, the operation of which is synchronized with the BHTM ID (18). Before starting work, the work of the selected unit from I to N of the application manager (21) is started and in the file format in UOI (15) are placed arrays of information about the customer, area of work and profiles, operators, measuring instruments are indicated in the unit for calibration of devices (22) array gauge calibration data. Using the binding module of the measuring installation (DUT) (8) of the GIS block (1), the position of the DUT on the ground is projected using raster and vector maps, as well as road tracks captured using GPS receivers. The same binding module (8) in the measured data storage module (4) stores the coordinates of the DUT electrodes for each picket. At the recording point in modules from i ... to n applications, each of which is equipped with its own special software, a unique array of operating units is created in BHTM ID (18), corresponding to the observation at this point, and in the file format, for example, .INI form an array of source data. Then, by means of the ADC (12) under the control of the data acquisition module (9), the signal from the receiving line in the form of an array of binary files (source data) is fed to a memory element, for example, the hard drive of the UNI (14) of the BHTM ID array (18) in a file format. If necessary, arrays with an anomalous level of interference are removed from these arrays of binary files using the unit for viewing, editing, converting (25) the support board (20). Then they start working in an array in which, at each accumulation of source data, the information signal (source data) processing module (5) suppresses such interference as interference elimination sectors (26), such as: emissions from lightning discharges and voltage drops in power lines, industrial periodic interference and high frequency noise. The efficiency of interference cancellation is controlled in the frequency domain. Processed transients are stored in the source data arrays, the number of which is determined by the number of channels kA _k . Then, through the compression sector of arrays (27), data is compressed within the time windows located in a logarithmic step into packages of operational units. At the next stage, the trend is eliminated by means of the trend elimination sector (28) and the compressed data is stored in the source data arrays B _k . When processing the initial data, the arrays B _k , depending on the modification of the DUT, enter the input sector of the formation of the final array of operational units (31) for the DUT of the type line - line or DUT type loop - line. In this module, the resulting transient curves and differential-normalized parameters (DNP) are obtained, which are then placed in the input data modules of the file type in ASCII format, for example, .prn.

With these methods of collecting and processing the source data, significant machine time is required, which, however, provides an increase in the volume of measured data arrays for each time measurement cycle, which results in an increase in the quality of the resulting curves. To achieve a higher signal-to-noise ratio, a reprocessing module for compressed arrays of operational units (2D processing) (30) is used, in which arrays A _{k are} processed, while arrays of operational units with compressed initial data B _k are used only to display the state of the measured data at the input of the processing module (5). At the output of the processing module (5), the processed data is stored, and the compressed data is recalculated and stored in the arrays With _k . The resulting DNP curves are placed in the source data arrays in text (binary) formats, from which through the data transfer module for each selected array of operational units (10) they are transferred to the BHTM ID relational source data module (18). Processing data on profiles is automatic, all intermediate arrays of operating units are stored with unique names in the Source file directory. After the processing cycle is completed, these arrays are examined by the editing module (16) for analysis of the results, after which, if necessary, the settings of the processing module (5) are changed and a new processing of the source data array is performed. In the sector of formation of an array of operating units (29) and the sector of reprocessing compressed arrays of operational units (2D processing) (30), they are carried out through the same sector of trend elimination (28), in which it is possible to select filters. Filter coefficients are calculated in the module for calculating FIR filters (filters with Finite Impulse response) (21).

In the marine modification of the software-measuring complex, which is more complex than the ground, hydrographic data are processed together with transients.

As well as in ground-based DUTs, all modules are launched from the launch board (17) with embedded software, the operation of which is synchronized with the BHTM ID (18). Before starting work, the work of the selected unit from I to N application manager (19) is started and in the file format in UOI (15) are placed arrays of information about the customer, work area and profiles, the operators, measuring instruments and the corresponding device calibration unit are indicated (22 ) an array of calibration data for the instruments. In the binding module (8) of the measured data storage module (4), in modules from i ... to n applications, each of which is equipped with its own special software, a unique array of operational units of binary source data files in the .INI format is created in BHTM ID (18) . In addition, through the data acquisition module (9) (Sea), an array of operational units with the configuration of the measurement setup and all the initial data on the observation characteristics are entered into the BHTM ID. An array of operational units with the coordinates of design profiles, raster and vectorized maps are loaded into the GIS module (1) through the binding module (8) (Sea) onto the memory element of the UNI (14) in the BHTM ID (18). During the passage of the profile, the binding module of the measuring installation (8) collects initial data from several GPS receivers, depth sensors, an echo sounder and a multimeter, with which the current is measured. During transient measurements, this module forms a data packet with hydrographic information corresponding to the measured transient. The GIS block (1) of the binding module (8) transfers this package of arrays of operational units to the data collection module (9), which, through the ADC (12), transmits initial data on transient processes to the UNI.

After recording on the profile is completed, the array of source data is transferred to the UOI (15), where they are processed. As well as for a ground-based information system, the hydrographic information editing unit (24) eliminates errors and failures by the module for eliminating errors and failures of hydrographic information (32) in the initial data, after which the information signals (initial data) processing module (5) sequentially performs modules for eliminating interference (26), compressing arrays (27), eliminating trends (28), and the sector of formation of an array of operational units (29) form arrays in time windows and initial data are smoothed (edited, approximated) in the sector again processing compressed arrays operating units (30) and arranged in arrays C _k is operating units. A complete processing graph is performed exactly the same as in the ground modification.

Since hydrographic data comes from various sources - external measuring instruments, in the source data arrays of various formats and with different time steps by means of the hydrographic information editing module (24), these data are reduced to a single time grid in which transients are recorded. As a result, each transient from the array of source data C _k is assigned a hydrographic information, in which all kinds of failures are processed and eliminated, coordinates are recalculated and necessary corrections are introduced. All these data are compared in the interval boundary determination module (33), where continuous profile recording is divided into intervals with the required step. At the output of this module, arrays of source data (operating units) C _k are created in which hydrographic data are linked to transients compressed into time windows, as well as to an array of operating units in ASCII format of the .txt type, where the boundaries of the intervals are indicated and processed within these limits hydrographic information.

The next step, using an array of operational units of the .txt type and an array C _k in the sector of formation of the resulting arrays of operating units (31) for each interval, the resulting transient curves and differential-normalized parameters (DNP) are calculated.

The resulting DNP curves are placed in the source data arrays in text (binary) formats, from which through the data transfer module for each selected array of operational units (10) they are transferred to the BHTM ID relational source data module (18).

Arrays of source data C _k are subsequently used in the module for comparing the results of electromagnetic observations and hydrographic data (35) (Sea), as well as for mapping by time delays and hydrographic data. The module comparing the results of electromagnetic observations and hydrographic data (35) (Sea) allows you to compare the results of various observations on the profile, regardless of the direction in which it was traveled, control is carried out when the profile is repeated.

Using the readings of the current sensor and the potential difference between the electrodes on the receiving line during its transmission, the apparent cut resistance is calculated in the module for calculating the apparent electrical resistivity (34). The results of the conversion of the source data are also compared with hydrographic data and stored in arrays of operating units in a text (binary) format into a file array of the source information of BHTM ID (18).

Processing of data by profiles is automatic, all intermediate arrays of source data are stored in the Source array with unique names of operating units. After completion of the processing cycle, these arrays should be viewed through the unit for viewing, editing, converting (25) the processing results to analyze intermediate results, after which it is possible to change the settings and process the initial data.

In the sector of formation of an array of operating units (29) and the sector of reprocessing compressed arrays of operational units (2D processing) (30), they are carried out through the same sector of trend elimination (28), in which it is possible to select filters. Filter coefficients are calculated in the module for calculating FIR filters (filters with Finite Impulse response) (21).

To visualize the content of BHTM IDs, a viewing, editing, and converting unit is used (25). It reflects all available arrays of source data for recording points, and also with its help it is possible to build graph plans for the profile, calculate the convergence of ordinary and control measurements, evaluate the identity of measuring instruments, etc.

To place the source data from the measured data storage unit (4) in the UOI (15) from a relational array of source information, BHTM ID (18) convert part of the file array of source information BHTM ID (18) into an array of ASCII text file format. An array in this format is transmitted to the customer, since it is independent of the software and measuring complex and is convenient for viewing on other computers with other software.

In order to achieve stability, the measuring modules are calibrated monthly. A device calibration block (22) is connected to the ADC module, in which a sequence of bipolar rectangular pulses with a known amplitude is generated. In the module for collecting electromagnetic sounding data (9), the amplification factors of the measuring equipment of the measuring instrument are changed, for each coefficient in the file array of the initial information (data) BHTM ID record their array of initial data in binary format. Calibration constants are preliminarily calculated and stored in the measured data storage unit (BCH ID) (4) and in the file array of the initial information (data) in the BHTM ID (18). If the deviations exceed the permissible values, then from the file array of the source information (data) in the BHTM ID (18), the array with these constants is loaded into the data acquisition module (9), which during field recording stores the constants in the source data array. It is also possible to view and calculate statistics on the measured characteristics of the selected device. All blocks and their modules are launched by the launch board (17), whose operation is synchronized with the BHTM ID.

The existing structure of the software-measuring complex has proved its high adaptability to constantly changing requirements. At the same time, high productivity of field and office work was achieved. In the future, along with the improvement of individual modules, it is planned to create service blocks and modules for the geological department, including statistical analysis and data mapping in modules of geographic information systems.

Since the DNME method relates to pulsed methods of electrical exploration, its implementation requires a transition from analog to digital equipment. For example, you can take the seismic 24-bit sigma as the basis - Crystall CS5321 delta ADC. As a result, this program-measuring complex (PIK) was created on its basis, which is designed to collect, store and process electromagnetic sounding data, which can be adapted for any pulse method for information carriers on the Microsoft SQL Selver platform with minimal cost. The following power equipment can be used in a PIK: a transistor inverter, which converts the direct current of the generator into bipolar pulses with an interval of different pulse durations; control and protection board based on a program-logic integrated circuit (FPGA), for example, the American company ALTERA. It is based on “hard” logic and the ability to configure it to perform specified functions. When changing logic or programs embedded in the board, CAD MAX + PLUS II is used, which is an integrated environment for the development of digital devices based on ALTERA software-logic integrated circuits. At the same time, control signals are generated in the PIK, in which the signal (source data) is synchronized and converted in such a way as to obtain the necessary current shape, the desired duration and polarity, in the DUT supply line. And when the voltage is exceeded, it generates an error signal, which turns off the executive modules by means of a protection relay. The PIC also uses the integrated power bridge IGBT SkiiP. To implement the PIK, the receiving equipment is used - GIS, which performs the functions for the PIK according to the block diagrams shown in the drawings. Thus, the block of reference observations (23) collects geodetic, hydrographic, and other information by linking the source-receiver system in space. The DNP curves from the relational array of the initial information go to the data processing units (2) and (3), where the inversion is carried out in the framework of a one-dimensional conducting polarizing model using several operations - Nelder-Mead, main axes, and global minimization. Further development of PIK is associated with the improvement of individual modules.

Thus, an increase in the volume of measured data arrays for each time measurement cycle presented in operating units for batch transmission of data in the required format suitable for subsequent conversion operations, an increase in the number of simultaneously processed data arrays (complex performance), and PIK universality for different geophysical schemes soundings.
