Description

The invention relates to information, reference and control automated systems with program control of the technological process of transporting petroleum products and can be used to manage operational activities and technological operations in all organizations equipped with a ground-based collapsible field main pipeline with a “bell” connection and having several interconnected levels management.

The authors were faced with the task of developing an automated complex for monitoring the process of transporting petroleum products (APM) through a ground-based prefabricated field main pipeline with a “socket” connection (PMT) using the existing scientific and technical basis, allowing for:

remote control of the process of transporting petroleum products via PMT by continuously measuring the parameters of the pumped fuel (supply Q, m ³ /h; density ρ, kg/m ³ ; temperature t, ° C), calculating the total volume V, m ³ and final mass M, t ;

remote monitoring of operating and emergency operating modes of pumping stations by continuously measuring the current parameters of the pressure of the flow of the pumped petroleum product on the input line of the pumping station (Pin., MPa), the pressure on the output line of the pump station (Pout., MPa) and the number of revolutions of the motor shaft of a mobile pumping unit ( n, rpm);

collection and conversion of input signals coming from control devices into a digital code with subsequent processing of information and storage of operational and production information at PMT control facilities;

display of parameters of transported petroleum products on the display blocks of controllers of control posts of pumping stations (DP NS), equipped with outputs to external devices;

transfer of information with the results of measurements of the parameters of the pumped petroleum product and operating modes of the pumping station via two-way dispatch wireless communication channels from the PS PS to the monitoring and control units of the technological process of pumping petroleum products of mobile dispatch centers of pipeline divisions;

display of data with parameters of the petroleum product transportation process, operating and emergency operating modes of pumping stations on the technological diagram of the PMT operational section with location-referenced electronic map for the automated workstation (AWS) of the operator of the mobile control center of the pipeline division;

control of the technological process of pumping petroleum products through the PMT and technological operations of receiving petroleum products at the initial point, operating modes of mobile pumping units as part of pumping stations and dispensing petroleum products at the final point of the PMT;

generation of electronic primary accounting documents;

documenting the information received in electronic log books: operating modes of pumping stations; parameters of the fuel transportation process; accidents and malfunctions; orders and reports;

electronic information exchange between levels of control objects using a two-way dispatch wireless communication channel;

analysis of flow parameters and prompt response to changes in the dynamics of remotely monitored parameter indicators;

monitoring the technical condition of the pipeline, analyzing received information in order to prevent emergency situations;

coordinating the actions of reserve groups and patrol and emergency teams to eliminate accidents and malfunctions in a timely manner;

receiving orders, instructions, reports (control commands) and timely delivery to control objects, receiving confirmation of their execution.

Fulfillment of the listed requirements when developing an automated complex for monitoring the process of transporting petroleum products through a PMT with a “bell” connection will improve the reliability and efficiency of operation, optimize the operating modes of the pipeline and the required pumping performance.

During the analysis of scientific, technical and sources of patent information, analogues were identified that partially solve the problem posed.

Thus, a technological complex for the acceptance and delivery point of field main pipelines is known, containing lines for receiving and dispensing petroleum products, connected to the main pipeline and installed sequentially in the receiving line, a pressure sensor, a pressure relief unit connected through a bypass valve to a reserve tank, an air separator, a filter, a liquid meter and a sampler , and in the dispensing line there is an air separator, a filter and a liquid meter sequentially along the flow. Groups of tanks are connected in parallel to the oil product receiving line through shut-off valves, the volume of each of which depends on the productivity of the PMT (RU utility model No. 128282, F17D 3/01, 2012.12.11).

The disadvantage of the technical solution is its incomplete configuration in the receiving and issuing lines of the technological complex of the acceptance point, the lack of an automatic in-line density meter-thermometer, as well as the lack of promptness of information presentation and communication channels for transmitting data with measurement results from the pressure sensor and liquid meter to the control point.

A system for automated control and automatic protection of a main pipeline is known, including a server for automatic control of a main pipeline, connected via an integrated network to a server for supervisory control and management, while the server for automatic control of a main pipeline includes a storage module for a set of pre-selected pipeline operating modes, a set storage module pre-calculated transitions between pipeline operating modes, a module for monitoring the technological process of oil pumping, a module for automatically determining the readiness of process equipment for a transition between modes, a module for automatically generating commands for switching between modes from a storage module for a set of pre-selected pipeline operating modes or from a storage module for a set of pre-calculated transitions between pipeline operating modes, module for automatic generation of emergency stop commands for oil pumping stations (RU patent No. 2750479 C1, F17D 5/00 2006.01).

The disadvantage of the technical solution is the absence in the main pipeline control server of a module for monitoring the technical condition of the pipeline, a module for controlling and coordinating the actions of reserve groups and patrol and emergency teams for the timely elimination of accidents and malfunctions; module for generating orders, instructions, reports (control commands).

The closest in technical essence to the claimed technical solution and taken as a prototype is an automated complex for providing motor fuel to the organization's equipment, containing at the first level an automated system for the development and control of the organization's planned tasks, connected to a control center and with interconnected collection modules individually connected to this control center , processing and storage of current information and a module for assessing the efficiency values of technological processes of an automated control system of an organization located on the second level, the corresponding inputs of which are connected to an interconnected module for collecting, processing and storing current information and a module for assessing the efficiency values of technological processes of a motor fuel storage facility, which separately connected to the control center of the automated process control system of the motor fuel storage facility, located on the third level, the automated process control system of the motor fuel refueling facility, located on the fourth level, to the control center of which are separately connected interconnected modules for collecting, processing and storing current information and a module for assessing the efficiency values of technological processes of a motor fuel refueling facility, with control centers of the second, third and fourth levels connected to a two-way dispatch communication channel, and motor fuel level sensors in the tanks of the motor fuel storage facility of the third level and motor fuel level sensors in tanks and the motor fuel consumption sensors of the fuel dispensers at the facility for refueling equipment with motor fuel of the fourth level are connected to separate controllers located on the third and fourth levels, respectively (RU patent No. 2654896 C1, G05B 19/418 2006.01).

The main disadvantage of this solution is the absence at the control points of the control levels of an automated complex for providing motor fuel to equipment, organizing a module for monitoring the technical condition of the pipeline, a module for controlling and coordinating the actions of reserve groups and patrol and emergency teams, and a module for generating orders, instructions, reports (control commands).

The technical result of the invention proposed by the authors is to increase the efficiency of managing the pumping of fuel through the PMT due to the implementation of remote control of the parameters of the process of transporting petroleum products and automated control of the transportation process through the PMT at mobile control objects of all levels, expanding the functionality of control centers for prompt response to changes in the dynamics of remotely controlled indicators , ensuring the specified operating modes of the PMT and the required pumping performance* timely adoption of management decisions at the stage of pipeline operation.
