Description

The invention relates to computer technology, in particular to a system for optimizing the time of settling of oil products in storage tanks, depending on the distribution of the temperature of the oil over the height of the tank and the shape of the particles of contamination, implementing the use of new information technologies in the storage of oil products.

One of the ways to clean fuel from mechanical impurities is sedimentation. Preliminary sedimentation of the fuel allows to reduce a significant amount of mechanical impurities and water droplets even before filtering the fuel. The effectiveness of the sedimentation depends both on its duration and on the viscosity and density of the fuel, on the nature of the material of the pollution particles, their mass, size and shape. The higher the viscosity and density of the fuel and the lower the degree of conformity of the shape of the analyzed particles of pollution to the spherical shape, the slower the precipitation of particles of mechanical impurities and water droplets and, therefore, the longer it takes to settle the fuel.

The standard for settling fuel in tanks of fuel and lubricants services is established by order of the Air Transport Department of the Ministry of Transport of the RSFSR No. DV -126 of 10/17/1992 and is 4 hours per 1 meter of level. The sedimentation rate of particles of mechanical impurities in the range of ~ 0.07 mm / s corresponds to this standard. However, this norm does not take into account not only the density of the material of the particles of pollution, their size and shape, but also the density, viscosity and temperature of the fuel itself.

In work [3], a theoretically substantiated result of studying the processes of sedimentation of fuel in tanks is presented. This result shows that the velocity V _o (Stokes' formula) sedimentation particle contamination in aviation fuel depends on: the radius r _of contamination particles, the density ρ _of contamination particles, the density ρ _T and viscosity γ _T Fuel

$$V_o=\frac{2180{\mathrm{<figure-callout\; id="2"\; label="r\; s"\; filenames="00000019.png,00000020.png"\; state="\{\{state\}\}">r\; </figure-callout>}}_s^{}}{{\gamma }_T}\left(\frac{{\rho }_s}{{\rho }_T}-\mathrm{one}\right).\left(\mathrm{one}\right)$$

In turn, both fuel density ρ _T and fuel viscosity γ _T are functions of fuel temperature t:

$${\rho }_T={\rho }_{\mathrm{twenty}}-\left(0.8205-0.00013\cdot {\rho }_{\mathrm{twenty}}\right)\cdot \left(t-\mathrm{twenty}\right),\left(2\right)$$

$$\begin{array}{l}{\gamma }_T=1.8742-\mathrm{0,0362}t+\mathrm{0,0007}{t}^2-{10}^{-5}{t}^3-{10}^{-7}{t}^{\mathrm{four}}-{10}^{-7}{\mathrm{<figure-callout\; id="5"\; label="t"\; filenames="00000023.png"\; state="\{\{state\}\}">t</figure-callout>}}^5+\\ +{10}^{-10}{\mathrm{<figure-callout\; id="6"\; label="t"\; filenames="00000024.png"\; state="\{\{state\}\}">t</figure-callout>}}^6,\left(3\right)\end{array}$$

where: t is the current temperature of the fuel, ρ ₂₀ is the density of the fuel at a temperature of + 20 ° С indicated in the passport for fuel (t = + 20 ° С is the temperature of standard atmospheric conditions for aviation fuel).

Since formulas (1) - (3) are valid both for motor fuels related to light petroleum products and for special purpose liquid petroleum oils [4], we will build all further considerations for petroleum products.

Given this, the establishment of the estimated allowable time of settling of the oil product for each tank of the fuel and lubricant service can be determined only by considering the characteristics of the distribution of the temperature of the oil product over the height of each individual tank.

For this, the graph of the distribution of oil temperature over the height of the tank is divided into separate sections. As the end (boundary) points of the sections, graph points are considered at which the temperature of the oil product is measured by a special system for monitoring the parameters of the oil product by the height of the tank (not shown in the drawing).

Each section of the obtained graph partition is characterized by temperature values at its boundaries. In this case, the temperature of the lower boundary of one section is equal to the temperature of the upper boundary of the lower section adjacent to it.

Dividing the tank into sections allows you to more closely monitor changes in the sedimentation rate of particles of oil pollution, and, therefore, to more accurately determine the time it settles.

For this, according to formulas (1) - (3), the sedimentation particles of the pollution particles are determined for each boundary temperature of the selected section of the reservoir. Interpreting further the sedimentation particle sedimentation rate obtained for the temperature of the upper boundary of the reservoir section as the entry velocity to the reservoir section, and the sedimentation particle sedimentation velocity obtained for the temperature of the lower boundary of the reservoir section as the exit velocity from the reservoir section, the average sedimentation particle sedimentation rate at this section of the tank.

It should be noted that when calculating the average sedimentation rate of a pollution particle in each section of the tank, the shape of the analyzed pollution particle is also taken into account.

For this, on the basis of the concept of “particle shape” as “the degree of correctness of the structure or topography of the particle (usually the correct particle shape is spherical)” in accordance with GOST R 51109-97, adopted by the Decree of the State Standard of Russia of December 17, 1997 No. 413 and in force with 01/01/1999, the definitions are introduced [5]:

- mid-section of the particle - “the area of the projection of the particle onto the plane normal to the direction of particle motion, which determines the drag of the particle in the fluid flow”;

- the ratio of the mid-section - “the ratio of the area of the mid-section to the area of a circle whose diameter is equal to the largest size of the measured particle”.

The mid-section coefficient k, which is a characteristic of the shape of the pollution particle, varies within

$$0<k\le \mathrm{one}:\left(\text{four}\right)$$

k = 1 - for particles of regular (spherical) shape;

0 <k <1 - for particles whose shape does not correspond to a spherical shape.

The degree of correspondence of the particle shape to the spherical shape is determined by the value of its coefficient k of mid-section. The higher the degree of conformity of the shape of the analyzed particle to the spherical shape, the closer the value of its shape factor k to the midsection section to 1. And, conversely, the lower the degree of conformity of the shape of the analyzed particle to the shape of the spherical shape, the closer the value of its coefficient k to the midsection section to 0.

Since formulas (1) - (3) are valid only for particles of a spherical shape, to apply these formulas for particles of any other shape in [6, p. 64] from the condition that the settling rates of a spherical pollution particle with a diameter of d _eq and an arbitrary pollution particle are equal the same nature with the maximum linear size l _max and the shape characteristic (mid-section coefficient) k the formula

$$d_{\mathrm{uh}\mathrm{to}\mathrm{at}}=l_{\max }\sqrt{k},\left(\text{5}\right)$$

where d _equiv is the diameter of the equivalent spherical pollution particle, l _max is the maximum linear size of the non-spherical pollution particle, k is the midsection coefficient of the non-spherical pollution particle.

The coefficient of the mid-section k of a non-spherical pollution particle is also a function of l _max [6, p.135]

$$k=\mathrm{one}-8.45\times {10}^{-2}\sqrt{l_{\max }-1.25}.\left(\text{6}\right)$$

In accordance with formulas (5) and (6), an arbitrary pollution particle (such as quartz) with the largest linear size l _max will move (settle) in the direction of the bottom of the tank at the same speed as a spherical particle with a diameter of d _equiv .

From the point of view of ensuring flight safety, the task of determining the settling time of the oil product in storage tanks for pollution particles (such as quartz) of arbitrary shape and size is of greatest interest.

$$l_{\max }\ge \delta \left(7\right)$$

where l _max = 2r _s (r _{s is the} radius of the pollution particle), δ (Table 1) is the mounting gap between the spool and the sleeve for various regulatory elements of the pump-controller of an aircraft gas turbine engine [7].

Table 1 No. p / p Spool pairs of fuel control equipment for aircraft gas turbine engines The gap, δ [μm] one Throttle Valve - Bushing 8-12 2 Differential Pressure Valve Spool - Bushing 7-9 3 Control Valve - Bushing 10-14 four Hydraulic retarder stem - coupling 6-8 5 Plunger - sleeve 15-22 6 Relief Valve Spools - Bushing 5-8

It should be noted that contamination particles (such as quartz) with a size of 5-10 μm have a very low sedimentation rate due to the manifestation of sedimentation-diffusion equilibrium when the Brownian motion speed approaches the sedimentation (sedimentation) velocity. Therefore, to remove these particles after sedimentation of the oil in the tanks, a filtration system with a refinement fineness of less than 3 microns is used.

With this in mind and in accordance with table 1, the values of l _max in the formula (7) are taken equal to 12-22 microns.

Assuming the largest linear particle size of a contaminant (such as quartz) of arbitrary shape

$$l_{\max }=2r_s\left(\text{8}\right)$$

and substituting it into (5), we obtain that the radius of the equivalent spherical pollution particle has the form

$$r_{\mathrm{uh}\mathrm{to}\mathrm{at}}=r_s\sqrt{k}.\left(9\right)$$

Then, in accordance with (1), the sedimentation rate of a spherical pollution particle of equivalent radius r _equiv has the form

$$V_o\left(r_{\mathrm{uh}\mathrm{to}\mathrm{at}}\right)=\frac{2180\cdot r_{\mathrm{uh}\mathrm{to}\mathrm{at}}^2}{{\gamma }_T}\left(\frac{{\rho }_s}{{\rho }_T}-\mathrm{one}\right).\left(\text{10}\right)$$

Substituting (9) into (10), we obtain

$$V_o\left(r_{\mathrm{uh}\mathrm{to}\mathrm{at}}\right)=\frac{2180\cdot {\mathrm{<figure-callout\; id="2"\; label="r\; s"\; filenames="00000019.png,00000020.png"\; state="\{\{state\}\}">r\; </figure-callout>}}_s^{}}{{\gamma }_T}\left(\frac{{\rho }_s}{{\rho }_T}-\mathrm{one}\right)\cdot k.\left(\text{eleven}\right)$$

From (11), taking into account (1) and (8), we obtain

$$V_o\left(d_{\mathrm{uh}\mathrm{to}\mathrm{at}}\right)=V_o\left(l_{\max }\right)\cdot k,\left(\text{12}\right)$$

where V _o (d _equiv ) is the sedimentation rate of a spherical pollution particle of equivalent diameter, equal to the sedimentation rate of a pollution particle with the largest linear size l _max and midsection coefficient k (condition (5)), V _o (l _max ) is the sedimentation velocity of a spherical particle pollution with a diameter of l _max , k is the mid-section coefficient of a pollution particle with the largest linear size l _max .

It follows from expression (12) that the sedimentation rate of a pollution particle (such as quartz) of any arbitrary shape with the largest linear size l _max and midsection coefficient k is the product of the sedimentation rate of a spherical pollution particle of the same nature with a diameter l _max and the midsection section coefficient k, corresponding to the shape of a non-spherical particle with the largest linear size l _max .

In accordance with (12), the average sedimentation rate for each pollution particle of arbitrary shape with the largest linear size l_max and the mid-section coefficient k at each section of the reservoir can also be represented by the product of the average sedimentation rate of a spherical pollution particle with a diameter l_max by the coefficient of the mid-section k of a non-spherical particle with the largest linear size l_max.

Hence, knowing the height of each section of the reservoir, it is possible to determine the time of settling of particles in this section by the ratio of the height of the considered section to the average sedimentation rate of pollution particles in this section, which, by analogy with (13), has the form

$$T_o\left(d_{\mathrm{uh}\mathrm{to}\mathrm{at}}\right)=T_o\left(l_{\max }\right)\cdot \raisebox{1ex}{$\mathrm{one}$}\!\left/ \!\raisebox{-1ex}{$k\text{'}\text{'}\left(\mathrm{fourteen}\right)$}\right.$$

- обратная величина коэффициента миделевого сечения для частиц не сферических с наибольшим линейным размером l_max.where T _o (d _equiv ) is the sedimentation time of spherical pollution particles with a diameter of d _equiv equal to the sedimentation time of non-spherical pollution particles with the largest linear size l _max and mid-section coefficient k (condition (5)), T _o (l _max ) - settling time for spherical particles of pollution with a diameter of l _max , $$\raisebox{1ex}{$\mathrm{one}$}\!\left/ \!\raisebox{-1ex}{$k$}\right.$$

is the reciprocal of the mid-section coefficient for non-spherical particles with the largest linear size l _max .

для частиц не сферических с наибольшим линейным размером l_max и коэффициентом миделевого сечения k.Expression (14) shows that the settling time of any arbitrary pollution particle (such as quartz) with the largest linear size l_max and the characteristic of the form k is the product of the settling time for spherical particles of pollution with a diameter l_max, and the reciprocal of the mid-section coefficient $$\raisebox{1ex}{$\mathrm{one}$}\!\left/ \!\raisebox{-1ex}{$k$}\right.$$

 for non-spherical particles with the largest linear size l_max and midsection coefficient k.

The total set of obtained time intervals for all sections of the reservoir will determine the estimated time of sedimentation of the oil product in the reservoir.

In this regard, it seems advisable to create such an automated system that would allow us to identify the readiness of the oil product in storage tanks for the issuance of the average sedimentation rate of pollution particles (such as quartz) of arbitrary shape in each section of the tank and give the settling time of the oil product as for each individual section of the tank, and the tank as a whole.

Known systems that could be used to solve the problem [1, 2].

The first of the known systems contains a central processor module, the inputs of which are connected to the memory modules and to the data preparation and input modules, and the outputs are connected to the corresponding memory modules, the data processing module, the information inputs of which are connected to the outputs of the corresponding memory modules, the synchronizing inputs are connected to the control the outputs of the central processor module, and the output of the module is the information output of the system [1].

A significant drawback of this system is its low speed, due to the fact that the execution of analytical data processing procedures is carried out by searching data across the entire database, which, when the database is large, inevitably leads to unreasonably large time spent on obtaining analytical estimates.

Another system is known that contains a module for identifying the base address of the oil product section, a module for identifying the base address of the tank page, a module for generating signals for reading parameters of the tank section, a module for registering parameters for the tank section, a module for generating call signals for the subroutine for calculating the sedimentation rate of particles of oil contamination, a module for registering sedimentation speed particles of oil product contamination, a selection module for the average particle sedimentation rate over a portion of the reservoir contamination of the oil product, a module for comparing the average sedimentation rate of the particles of oil pollution with the standard sedimentation rate, a module for identifying the base address of the height of the reservoir section, a module for generating signals for reading the average estimated time of settling of the oil product in the reservoir section, and a module for recording the average the allowable time of sedimentation of the oil product, the module issuing the estimated allowable time of sedimentation of the oil product [2].

The last of the above technical solutions is closest to the technical solution described in the application.

Its disadvantage lies in the narrow functionality of the system, limited to the analysis and processing of pollution particles of only the correct (spherical) shape, which leads to the exclusion from the analysis and processing of pollution particles of any other arbitrary shapes that settle at the same sizes much slower than spherical, which leads to distortion the result of sedimentation of the oil product both in each individual section of the tank and throughout the tank as a whole.

The purpose of the invention is the expansion of the functionality of the system, which allows in the process of sedimentation of the oil product in the storage tank to analyze and process contamination particles not only of a regular (spherical) shape, but also particles of any other arbitrary shape.

All nodes and elements of the system are made on standard potential-impulse elements.

A remote workstation (AWP) of a system user consists of a terminal having a screen for displaying a query codegram and system signals, and a personal computer keyboard. Presentation of readable codes of the parameters of the sections of the reservoir, sedimentation rates of the particles of contamination at the boundaries of each section of the reservoir, the settling time of the oil product in the sections of the reservoir and the reciprocal of the mid-section coefficient of the analyzed particles of contamination are controlled from the server (not shown).

The system operates as follows.

For each type of oil product poured into the tanks of the fueling complex (TZK), the system associates a certain section of the server database, and each tank with this type of oil product associates a page with the allocated memory section.

In this case, the read address of the parameters of any section of the tank under consideration is represented as a relative address shifted relative to the base address of the page of the tank by a code corresponding to the identifier of the processed section of the tank.

The parameters of the reservoir section are the temperature of the upper boundary of the section, the temperature of the lower boundary of the section, the height of the section and a certain number equal to the total number of temperature values in the section of the tank.

The system associates with each temperature of the reservoir section a value of the sedimentation rate of particles of oil product contamination. Next, the average sedimentation rate of oil product particles settling over the reservoir section is determined and compared with the standard sedimentation particles pollution rate for deciding on the choice of the system operation mode.

The system associates with the height code of the reservoir section some base address of the height of the reservoir section, starting from which the server stores the relative addresses of the ratios of the height of the reservoir section to the average sedimentation rate of oil pollution particles in the reservoir section.

The offset of each relative address of the ratio of the height of the reservoir section to the average on the plot of the sedimentation particle velocity of the pollution relative to the base address of the height of the reservoir section is determined as the code average on the plot of the sedimentation particle pollution rate n. Namely, the code of the ratio of the height of the reservoir section to the average sedimentation particle sedimentation rate of the pollution particles is interpreted by the system as the code of the settling time of the oil product in the reservoir section.

The system then contacts the server to execute a subroutine for calculating the inverse of the mid-section coefficient for the analyzed particles of contamination. After this, the settling time of the particles of the treated section of the tank is multiplied with the obtained inverse value of the coefficient of the mid-section and is given to the user's workstation.

This procedure is performed after processing each section of the oil storage tank. Upon completion of the analysis of all sections of the reservoir, the system gives the user the time to settle the oil product throughout the tank, which is the sum of the adjusted time intervals of all sections of the reservoir.

Thus, by identifiers of the oil product, the tank and its sections, the system determines the settling time of the oil product in each section of the tank, corrects it according to the shape of the particles of contamination and issues the system user to the workstation. The end of the scanning of the tank sections ends with the issuance of the total settling time for the tank to the user's workstation.

For this, the user of the system at his workplace generates a query codogram, which indicates the identifier of the oil product, the identifier of the tank, the identifier of the upper part of the tank, the identifier of the lower part of the tank, the density of the oil under standard atmospheric conditions, the density of the pollution particle, the radius of the pollution particle and the standard particle settling rate oil product pollution (table 2).

The generated code from the workstation of the user of the system is fed to the information input 15 of the system and fed to the information input 50 of the module 1 for identifying the base address of the oil product section and entered into register 40 by a synchronizing pulse supplied to the synchronizing input 51 of module 1 from the synchronizing input 20 of the system.

The oil product code from the output 54 of register 40 is fed to the input of the decoder 41. The decoder 41 decrypts the oil product code and generates at one of its outputs a high potential supplied to the corresponding inputs of elements 43-45 I. For definiteness, we assume that the high potential from the output of the decoder 41 will be open element 45 And one input.

The clock pulse from the input 20 of the system, passing through the input 51, is delayed by the delay element 47 for the response time of the register 40 and the decoder 41 and enters through the element 45 And open to one input of a fixed cell of a read-only memory (ROM) 42. In a fixed cell of the ROM 42, the code of the base address of the petroleum product section is stored, the pages of which store information on the petroleum product parameters for all sections of each reservoir with the requested petroleum product.

The code of the base address of the oil product section from the output 62 of the ROM 42 is sent to the information input 84 of the module 2 for identifying the base address of the tank page and fed to one input of the adder 77.

The tank code from the output 55 of the register 40 goes to the output 63 of the module 1 and is sent to the information input 83 of the module 2 and is fed to the input of the decoder 75. The decoder 75 decodes the tank code and generates at one of its outputs a high potential that goes to the corresponding inputs of the elements 78- 80 I. For definiteness, let us assume that the high potential from the output of the decoder 75 will open the element 80 And one input.

The clock pulse from the output of the delay element 47 is delayed by the delay element 48 for the time of reading the fixed cell of ROM 42 of module 1 and the operation of the decoder 75 of module 2 and arrives through the element 80 And open to one input and to the input of the fixed cell of read-only memory (ROM) 76. In the fixed cell ROM 76 stores the offset code of the base address of the tank page relative to the base address of the section of the oil product. This code from the output of the ROM 76 is fed to another information input of the adder 77.

According to the synchronizing pulse from the output 70 of the module 1, delayed by the delay element 81 for the time of reading the fixed cell of the ROM 76, in the adder 77, the codes supplied to its inputs are summed. From the output of the adder 77, the code of the base address of the reservoir page is removed, starting from which the oil product parameters for each section of the reservoir are stored in the server database.

The code of the base address of the tank page from the output 86 of module 2 is sent to the information input 104 of the module 3 for generating signals for reading the parameters of the tank section and fed to one information input of the adder 93.

The code of the upper part of the tank (the beginning of scanning) from the output 56 of the register 40 of module 1 is sent to the information input 103 of module 3 and fed to the information input of the counter 89, where it is recorded by the synchronizing pulse from the output of the delay element 81, delayed by the delay element 82 for the duration of the adder 77 and applied to the synchronizing input 105 of the module 3.

The code of the tank section from the output of the counter 89 is fed to the input of the decoder 91. The decoder 91 decrypts the code of the tank section and generates at one of its outputs a high potential supplied to the corresponding inputs of elements 94-96 I. For definiteness, we assume that the high potential from the output of the decoder 91 element 95 And one input will be opened.

The synchronizing pulse from the input 105 of module 3 passes the PI element 98, is delayed by the delay element 99 for the time the tank level code is entered into the counter 89 and the decoder 91 is activated, and enters through the element 95 And open at one input and to the input of a fixed cell of a read-only memory (ROM) 92 . In a fixed cell ROM 92 is stored code offset address of the section of the tank relative to the base address of the page of the tank. This code from the output of the ROM 92 is fed to another information input of the adder 93.

According to the synchronizing pulse from the output of the delay element 99, delayed by the delay element 100 for the reading time of the fixed cell of the ROM 92, in the adder 93, the codes supplied to its inputs are summed. The output of the adder 93 is removed the code of the relative address of the upper section of the tank, which stores the parameters of the oil product of this section of the tank.

The code of the relative address of the upper section of the tank from the output of the adder 93 is fed to the information input of the register 90, where it is entered by the synchronizing pulse from the output of the delay element 100, delayed by the delay element 101 for the duration of the operation of the adder 93.

The same pulse from the output of the delay element 101 is delayed by the delay element 102 for the response time of the register 90 and from the output of the system 31 is fed to the input of the first server interrupt channel.

With the arrival of this impulse, the server switches to a subprogram for interrogating the contents of its database at the address generated on the address output 25 of the system and issuing the read parameters of the upper section of the tank to the information input 16 of the system.

The parameters of the read upper section of the tank from the information input 16 of the system are supplied to the information input 118 of the register 115 of the module 4 for registering the parameters of the tank section, where they are entered by the synchronizing pulse of the server, which arrives at the synchronizing input 119 of the register 115 from the input 21 of the system.

The same pulse from the input 119 of the module 4 is delayed by the delay element 117 and from the output 127 of the module 4 is sent to the synchronizing input 152 of the signal generation module 5 of the subroutine for calculating the sedimentation rate of the oil pollution particles, the OR element 140 passes and enters the counting input of the counter 135, increasing it content per unit.

The counter 135 counts on an accrual basis the number of calls to the server database subroutine when processing parameters of one section of the tank and forwards each time its contents to one information input of the comparator 136. To another information input 150 of the comparator 136 from the output 123 of module 4, the code of the total number of all calls of the subprogram server database for the cycle of processing the parameters of one section of the tank.

The code of the total number of all calls to the server database subroutine for the processing cycle of the parameters of one section of the tank corresponds to the number of temperature parameters of the processed section of the tank.

According to the clock pulse from the output of the OR element 140, delayed by the delay element 142 for the increment time of the counter 135 and fed to the synchronizing input of the comparator 136, the comparator 136 compares the codes at its inputs.

Given that at the moment in time, only the first call to the server database routine was received, the contents of counter 135 will be less than the code for the total number of calls to the routine fed to input 150 of comparator 136 from output 123 of module 4.

In this case, a signal is generated at the output 155 of the comparator 136, which passes through the AND elements of group 137 from the input 149 of module 5 the temperature code of the upper boundary of the upper section of the tank to the information input of the register 134, where it is entered by the synchronizing pulse from the output of the delay element 142, delayed by the element 143 delays for comparator response time 136.

The same pulse from the output of the delay element 143, delayed by the delay element 144 for the response time of the register 134, from the output of the system 32 is fed to the input of the second channel of the server interrupt.

With the arrival of this impulse, the server polls its information inputs and takes from the system output 27 the temperature code of the upper boundary of the upper section of the tank, issued from the output of register 134 of module 5, and from the information output 28 of the system, the standard fuel density code, the particle density code and the radius code particles of pollution, issued from the output 58 of the register 40 of module 1, and returns from its database to the information input 17 of the system correspondence in the form of a code of the sedimentation rate of pollution particles on the upper Anice of the upper section of the tank.

From the information input 17 of the system, the code for the sedimentation rate of the particles of contamination on the upper boundary of the upper section of the tank is fed to the information input 165 of the register 161 of module 6, where it is entered by the synchronizing pulse of the server to the input 22 of the system.

The same pulse from the input 166 of module 6 is delayed by the delay element 163 for the time the register is triggered and fed to the counter input of the counter 160, increasing its content by one. The counter 160 counts on an accrual basis the number of speed codes received in the register 161 from the server when processing the parameters of one section of the tank, and sends each time its contents to the information input 186 of the comparator 176 of module 7.

To another information input 187 of comparator 176, output 123 of module 4 provides a code for the total number of all calls to the server database subroutine during the processing cycle of the parameters of one section of the tank.

According to the synchronizing pulse from the output of the delay element 163, delayed by the element 164 for the increment of the counter 160 and supplied from the output 171 of the module 6 to the synchronizing input 189 of the module 7, the comparator 176 compares the codes at its inputs.

Given that at the moment in time, only the first result of the processing cycle of the parameters of the reservoir section was entered in register 161, the contents of the counter 160 equal to one will be less than the code for the total number of calls to the server database routine. In this case, a signal will appear at the output 193 of the comparator 176, which opens the element 180 AND on one input.

The synchronizing pulse from the input 189 of module 7, delayed by the delay element 183 for the response time of the comparator 176, passes through element 180 and allows the passage of the code for the sedimentation rate of oil pollution particles at the upper boundary of the upper section of the tank from the output 170 of the register 161 of module 6 through the And elements of group 178 to one input of the adder 177.

The same pulse from the output of element 180 AND is supplied to the installation input 168 of module 6, the OR element 162 passes, and fed to the installation input of the register 161, preparing it for the next operation cycle.

The same pulse from the output 196 of module 7 is supplied to the synchronizing input 153 of module 5, the OR element 140 passes, and enters the counting input of the counter 135, increasing its content by one.

The same pulse from the input 153 of the module 5 passes the element 141 OR and enters the installation input of the register 134, preparing it for the next cycle of work.

The new contents of the counter 135 are fed to one information input of the comparator 136, to the other information input 150 of which, from the output 123 of module 4, the code of the total number of all calls of the server database subroutine for the processing cycle of the parameters of one section of the tank is supplied.

According to the clock pulse from the output of the OR element 140, delayed by the delay element 142 for the increment time of the counter 135 and fed to the synchronizing input of the comparator 136, the comparator 136 compares the codes at its inputs.

Given that at the moment in time, the second call to the subprogram call has already been taken, the contents of counter 135 will be equal to the code of the total number of calls to the server database subprogram supplied to input 150 of comparator 136 from output 123 of module 4.

In this case, a signal is generated at the output 156 of the comparator 136, which passes through the And elements of group 138 to the information input of the register 134 the temperature code of the lower boundary of the upper section of the tank, where it is entered by the synchronizing pulse from the output of the delay element 142, delayed by the delay element 143 for the time the comparator operates 136.

The same pulse from the output of the delay element 143, delayed by the delay element 144 for the response time of the register 134, from the output of the system 32 is fed to the input of the second channel of the server interrupt.

With the arrival of this impulse, the server polls its information inputs and takes from the system information output 27 the temperature code of the lower boundary of the upper section of the tank, issued from the output of register 134 of module 5, and from the information output of the system 28, the standard oil product density code, the particle density code and the radius code particles pollution, issued from the output 58 of the register 40 of module 1, and returns from its database to the information input 17 of the system in the form of a code for the sedimentation rate of particles of oil pollution product at the lower boundary of the upper portion of the tank.

From the information input 17 of the system, the code for the sedimentation rate of the particles of contamination on the lower boundary of the upper section of the tank goes to the information input 165 of the register 161 of module 6, where it is entered by the synchronizing pulse of the server to the input 22 of the system.

The same pulse from the input 166 of module 6 is delayed by the delay element 163 for the time the register is triggered and fed to the counter input of the counter 160, increasing its content by one.

The new content of the counter 160 is fed to the information input 186 of the comparator 176 of module 7. The other information input 187 of the comparator 176 from the output 123 of module 4 is supplied with the code of the total number of all calls to the server database routine for the processing cycle of the parameters of one section of the tank.

According to the synchronizing pulse from the output of the delay element 163, delayed by the element 164 for the increment of the counter 160 and supplied from the output 171 of the module 6 to the synchronizing input 189 of the module 7, the comparator 176 compares the codes at its inputs.

Given that at the moment in time, the second call to the server database routine was already performed when processing the parameters of one section of the tank, the contents of the counter 160 will be equal to the code of the total number of calls to the server database routine. In this case, a signal appears at the output 194 of the comparator 176, which opens a single input element 181 And one input.

The synchronizing pulse from the input 189 of the module 7, delayed by the delay element 183 for the response time of the comparator 176, passes through the element 181 open at one input and allows the passage of the code for the sedimentation rate of oil pollution particles corresponding to the temperature of the lower boundary of the upper section of the tank from the output 170 of the module register 161 6 through the elements And groups 179 to another input of the adder 177.

According to the same pulse, from the output of element 181 I, the adder 177 sums up the sedimentation rate codes for the particles of oil contaminants fed to its inputs, with the result being output to the information input of the shift register 175.

According to the pulse from the output of the element 181 AND, delayed by the delay element 184 for the operation time of the adder 177, the contents of the register 175 are shifted to the right by one digit and, in the form of a code of the average sedimentation rate of oil pollution particles in one (upper) section of the tank, from the information output 195 of module 7 is issued to the information input 207 of the comparator 200 of the module 8 comparing the average sedimentation rate of the particles of oil pollution with the standard sedimentation rate over the reservoir section. At the other input 208 of the comparator 200, a code of the standard sedimentation particle rate of pollution from the output 67 of the module 1 is supplied.

The clock pulse from the output of the delay element 184, delayed by the delay element 185 for the duration of the shift register 175, is output from the output of the module 7 197 to the installation input 167 of the module 6 and is supplied to the installation input of the counter 160, returning it to its original state. The same pulse from the input 167 of module 6 passes through the OR element 162 and enters the installation input of the register 161 and resets its contents to zero, preparing it for the next cycle of operation.

The pulse from the output 197 of module 7 is also supplied to the installation input 154 of module 5 and is supplied to the installation input of the counter 135, returning it to its original state. The same pulse from the input 154 of the module 5 passes the element 141 OR and enters the installation inputs of the register 134, preparing it for the next cycle of work.

In addition, the pulse from the output 197 of the module 7 supplied to the synchronizing input 209 of the module 8 in the comparator 200 compares the codes of the speeds applied to its inputs,

If the code of the average on the site of the reservoir sedimentation rate of particles of oil pollution is greater than or equal to the code of the standard sedimentation rate, then the output 211 of the comparator 200 produces a signal that opens the element 203 And one input.

In this case, the synchronizing pulse from the input 209 of module 8, delayed by the delay element 204 for the response time of the comparator 200, passes through the element 203 And open at one input and, from the output 214 of the module 8, goes to the synchronizing input 223 of the module 9 for identifying the base address of the height of the tank section.

If the code of the average sedimentation rate of oil pollution particles in the tank section is less than the code of the standard sedimentation rate of oil pollution particles, then a signal is generated at the output 210 of the comparator 200, which opens the element 202 And at one input.

In this case, the synchronizing pulse from the input 209 of module 8, delayed by the delay element 204 for the time the comparator 200 operates, passes through the And element 202 open to one input to the synchronizing input of the comparator 201.

Since the system allows a lower than the standard average sedimentation rate of oil pollution particles only in the lower section of the tank, the code of each current section of the tank, the parameters of which are currently being processed by the system, is checked for compliance with the code of the lower section of the tank.

To this end, the input 205 of the comparator 201 is supplied with the code of the currently processed tank section from the output 110 of module 3, and the input of the comparator 206 is the code of the lower section of the tank from the output 65 of module 1.

If the average settling rate of particles of oil product contamination in the treated area is less than the normative, and the site codes at the inputs of the comparator 201 do not coincide, then at the output 213 of the comparator 201 the signal "Oil is not ready for delivery" is generated. This signal from the output 213 of the comparator 201 is fed to the signal output 36 of the system and sent to the automated workstation (AWP) of the user of the system, who set the initial codogram of the request for input 15 of the system.

In parallel with the issuance by the user of the system of the system from the output 213 of the module 8 of the oil unavailability signal to the output of this signal, the system is reset and it is returned to its original state.

To do this, the signal from the output 213 of module 8 is supplied:

- to the installation input 52 of module 1, the OR element 46 passes through and enters the installation input of the register 40, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 107 of module 3, the OR element 97 passes and enters the installation input of the counter 89, returning it to its original state;

- to the installation input 120 of module 4, the OR element 116 passes and enters the installation input of the register 115, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 190 of module 7, the OR element 182 passes and enters the installation input of the shift register 175, resetting its contents to zero and preparing it, thereby, for a new operation cycle.

If the sedimentation rate of particles of oil product contamination, the average on the treated section of the tank, is less than the norm, and the codes of the sections at the inputs of the comparator 201 are the same, then at the output 212 of the comparator 201 the signal “Oil is ready to issue” is generated. This signal from the output 212 of the comparator 201 is sent to the signal output 37 of the system and sent to the automated workstation (AWP) of the user of the system, who set the initial codogram of the request for input 15 of the system. The same signal from the output 212 of module 8 is supplied to the synchronizing input 224 of the module 9 for identifying the base address of the height of the tank section.

At the information input 222 of module 9, the code for the height of the tank section from the output 126 of module 4 is supplied to the input of the decoder 215. The decoder 215 decodes the code for the height of the tank section and generates a high potential at one of its outputs, which goes to the corresponding inputs of elements 217-219 I. For definiteness, suppose that a high potential from the output of the decoder 215 will open the element 217 And one input.

Each synchronizing pulse from inputs 223 and 224 of module 9, passing through an OR element 220, also passes through an element 217 AND open to one input of a fixed cell of a read-only memory device (ROM) 216. A code of the base address of the section height is stored in a fixed cell of the ROM 216 reservoir, starting from which the codes of the estimated allowable time of settling of the oil product corresponding to the code of the average sedimentation rate of particles of oil pollution on e th site.

The code of the base address of the height of the tank section from the output 225 of module 9 is sent to the information input 242 of the module 10 for generating signals for reading the codes of the time that the oil settles on the sections of the storage tank and enters one information input of the adder 233.

Each receipt of the code of the average site sedimentation rate of oil product particles at the input by the decoder 231 from the output of module 195 7 is decrypted by the decoder with the generation of high potential at one of its outputs. This potential from one of the outputs of the decoder is supplied to the corresponding inputs of the elements 234-236 I. For definiteness, suppose that the high potential from the output of the decoder 231 will open the element 235 And one input.

In this case, the synchronizing pulse from the output of the element 220 OR module 9, delayed by the element 221 of the delay for reading the fixed cell ROM 216, when it enters the input 243 of the module 10 from the output 226 of the module 9 passes through the element 235 And open to the reading input fixed to one cells of read-only memory (ROM) 232.

In a fixed cell of ROM 232, a code is stored for the offset address of the readout of the code for settling the oil product in the tank section corresponding to the code of the average sedimentation rate of oil pollution particles in this section and received at the input of the decoder 231, relative to the base address of the height of the tank section already at the same input of the adder 233 The offset code of the read address of the sedimentation time code of the oil product in the tank section from the output of the ROM 232 is supplied to another input of the adder 233.

According to the synchronizing pulse from the input 243 of the module 10, delayed by the delay element 238 for the time of reading the fixed cell of the ROM 232, in the adder 233 the codes received at its inputs are summed up with the output of the register 230 of the relative reading address of the sedimentation time code of the oil product in the tank section.

The synchronizing pulse from the output of the delay element 238, the delayed delay element 239 for the operation time of the adder 233, the relative address of the readout of the code of the time of sedimentation of the oil product in the tank section is entered in the register 230.

The same pulse from the output of the delay element 239, delayed by the delay element 240 for the response time of the register 230, is output from the system output 33 to the input of the first server interrupt channel.

With the arrival of this impulse, the server switches to the subprogram for interrogating the contents of its database at the address generated on the address output 26 of the system and issuing the read code for the time of settling of the oil product in this section of the tank to the information input 18 of the system.

From the information input 18 of the system, the time code for settling the oil product over the tank section is fed to the information input 253 of the register 250 of the module 11 for generating call signals of the subroutine for calculating the reciprocal of the mid-section coefficient, where it is entered by the server synchronizing pulse received at the system input 23.

The same server pulse from the input 254 of module 11, delayed by the delay element 252 for the response time of the register 250, is output from the system output 34 to the input of the second server interrupt channel.

With the arrival of this impulse, the server polls its information inputs and takes from the information output 28 of the system the code of the radius of the processed particles of pollution r _s , issued from the output 58 of register 40 of module 1, executes the program for calculating the value

$$\raisebox{1ex}{$\mathrm{one}$}\!\left/ \!\raisebox{-1ex}{$k$}\right.=\frac{\mathrm{one}}{\mathrm{one}-8.45\times {10}^{-2}\sqrt{2r_s-\mathrm{one}b25}}$$

.(where r _z is the radius of the pollution particle, k is the mid-section coefficient) and returns from its database to the information input 19 of the system a correspondence in the form of a code of the reciprocal of the mid-section coefficient $$\raisebox{1ex}{$\mathrm{one}$}\!\left/ \!\raisebox{-1ex}{$k$}\right.$$

.

поступает на информационный вход 271 регистра 260 модуля 12 коррекции времени отстаивания нефтепродукта в резервуаре хранения на форму частиц загрязнения, куда и заносится синхронизирующим импульсом сервера, поступающим на вход 24 системы.From the information input 19 of the system, the code of the reciprocal of the mid-section coefficient $$\raisebox{1ex}{$\mathrm{one}$}\!\left/ \!\raisebox{-1ex}{$k$}\right.$$

arrives at the information input 271 of the register 260 of the module 12 for the correction of the time of settling of the oil in the storage tank on the form of pollution particles, where it is entered by the synchronizing pulse of the server, which is input to the system 24.

подается на один информационный вход умножителя 262, на другой информационный вход 272 которого с выхода 257 модуля 11 подается код времени отстаивания нефтепродукта после анализа и обработки текущего участка резервуара хранения.From the output of register 260, the code of the reciprocal of the mid-section coefficient $$\raisebox{1ex}{$\mathrm{one}$}\!\left/ \!\raisebox{-1ex}{$k$}\right.$$

fed to one information input of the multiplier 262, to another information input 272 of which, from the output 257 of module 11, the code for the time of sedimentation of the oil after analysis and processing of the current section of the storage tank is supplied.

The same server pulse from input 273 of module 12, delayed delay element 266 for the response time of register 260, multiplier codes 262 are multiplied. The result of the multiplication in the form of an adjusted code of the time of sedimentation of the oil product from the treated section of the storage tank is fed to the summing input of the adder 263, and to the information input of the register 261.

The same server pulse from the output of the delay element 266, the delayed delay element 267 for the response time of the multiplier 262, the corrected time code for the sedimentation of oil from the processed section of the storage tank, received at the summing input of the adder 263, is entered into the adder 263 and added to the code contained in it. From the output of the adder 263, the corrected code of the time of sedimentation of the oil product from the treated section of the storage tank from the output 276 of the module 12 is fed to the information input 289 of the module 13 of the issuance of the codes of the time of sedimentation of the oil product in the storage tank.

The same server pulse from the output of the delay element 267, the delayed delay element 268 for the operation time of the adder 263, the adjusted code of the time of sedimentation of the oil from the current processed section of the storage tank, is entered in register 261. From where, from the output 277 of the module 12 is fed to the information input 286 of the module 13.

The same server pulse from the output of the delay element 268, delayed by the delay element 269 for the response time of the register 261, from the output 278 of the module 12 is supplied to the synchronizing input 290 of the comparator 280 of the module 13, which controls the completion of scanning of sections of the tank by comparing the codes of the sections supplied to its inputs .

If the code of the current processed section of the tank at the input 287 of the comparator 280 received from the output 110 of module 3 is not equal to the code of the lower section of the tank at its input 288 received from the output 65 of module 1, then the process of scanning and processing the parameters of the sections of the tank is not yet complete. In this case, a signal is generated at the output 291 of the comparator 280, which opens the element 281 I through one input.

Then the synchronizing pulse from the input 290 of module 12, delayed by the delay element 285 for the response time of the comparator 280, passes through the I element 281 open through one input and allows the output from the input 286 of the module 13 through the elements And 283 of the code group of the sedimentation time of the oil product from the processed section of the storage tank to the information output 293 of the module 13 and then to the information output 29 of the system, from where it is sent to the user's workstation.

The issuance of the user code after processing the portion of the storage tank of the oil sedimentation time code is accompanied by the issuance of the signal “The time of sedimentation of the oil product in the reservoir section” from the signal output 38 of the system to the user AWP.

Since not all sections of the tank have yet been scanned and processed, this signal from the output 295 of module 13 is used to prepare the system for operation in the next cycle.

To do this, the signal from the output 295 of module 13 is supplied, firstly, to the installation inputs of all those modules that will be used by the system when processing the parameters of the following sections of the tank, namely:

- to the installation input 121 of module 4, the OR element 116 passes and enters the installation input of the register 115, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 191 of module 7, the OR element 182 passes and enters the installation input of the shift register 175, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 245 of the module 10, the OR element 237 passes and enters the installation input of the register 230, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 255 of module 11, the OR element 251 passes and enters the installation input of the register 250, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 275 of module 12, the OR element 264 passes and enters the installation input of the register 260, resetting its contents to zero and thereby preparing it for a new operation cycle, and also the OR element 265 passes and enters the installation input of the register 261 , dropping to zero its contents and preparing it, thereby, for a new cycle of work.

Secondly, the signal from the output 295 of the module 13 is fed to the counting input 106 of the module 3, which forms the read signals of the parameters of the next section of the tank.

The newly generated synchronizing pulse, issued from the output 111 of the module 3 to the output 31 of the system, is again fed to the input of the first channel of the server interrupt.

With the arrival of this impulse, the server again switches to the subprogram for polling the contents of its database at the newly formed address, issued from the output of register 90 to the address output 25 of the system, and issuing the read parameters of the next section of the tank to the information input 16 of the system.

The described process of generating and selecting addresses of reservoir sections from the memory of the server database with subsequent processing of the parameters of each section of the reservoir will continue until not only addresses of all sections of the reservoir have been selected from the memory of the server database, but also the parameters of each section of the reservoir have been processed.

This will happen when the code of the current processed section of the tank supplied to the input 287 of the comparator 280 from the output 110 of module 3 is equal to the code of the lower (final) section of the tank supplied to the input 288 of the comparator 280 from the output 65 of module 1.

With the coincidence of the codes of the sections of the reservoir at the inputs 287 and 288 of the comparator 280, a signal is now generated at the output 292 of the comparator 280. This signal opens one input element 282 I.

In this case, the synchronizing pulse from the input 290 of the module 13, delayed by the delay element 285 for the response time of the comparator 280, passes through the I element 282 open through one input and allows the output from the input 289 of the module 13 through the elements 284 AND of the code group of the sedimentation time after passing processing all sections of the storage tank to the information output 30 of the system, from where it is sent to the user's workstation.

The issuance of the user code for the sedimentation time of the oil product after passing through and processing all sections of the storage tank is accompanied by the issuance of the signal “The time for the sedimentation of the oil product in the storage tank” from the alarm output 39 of the system.

The same signal from the output 296 of the module 13 is supplied to the installation inputs of all the modules of the system to prepare them for work to process the next codogram of the system user request received at the information input 15 of the system.

For this, the signal from the output 296 of module 13 is supplied:

- to the installation input 53 of module 1, the OR element 46 passes through and enters the installation input of the register 40, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 122 of module 4, the OR element 116 passes through and enters the installation input of the register 115, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 192 of module 7, the OR element 182 passes and enters the installation input of the shift register 175, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 256 of module 11, the OR element 251 passes and enters the installation input of the register 250, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 274 of module 12, the OR element 264 passes and enters the installation input of the register 260, resetting its contents to zero and thereby preparing it for a new operation cycle, and also the OR element 265 passes and enters the installation input of the register 261 , dropping to zero its contents and preparing it, thereby, for a new cycle of work;

- to the installation input 244 of module 10, the OR element 237 passes and enters the installation input of the register 230, resetting its contents to zero and preparing it, thereby, for a new operation cycle;

- to the installation input 108 of module 3, the OR element 97 passes and enters the installation input of the register 90, resetting its contents to zero and thereby preparing it for a new operation cycle, and to the installation input of the counter 89, returning it to its original state.

Thus, the introduction of new nodes and modules and new structural relationships has significantly expanded the functionality of the system, which allows the process of sedimentation of the oil in the storage tank to analyze and process contamination particles of any arbitrary shape, and, therefore, to give the most reliable results of the sedimentation of the oil product as separate sections of the storage tank, and throughout the tank as a whole.
