Description

The invention is intended to automate the processes of monitoring the availability and delivery of fuel (fuels and lubricants - fuels and lubricants) at auto-fueling trucks, aviation fueling trucks and auto-fueling oil-filling trucks that refuel vehicles on the basis of on-farm settlement.

There is a known system (RU 102795U1) for automated metering of diesel fuel in a fuel warehouse (ACS DT), which contains a device for automatic measurement of parameters and the amount of fuel in tanks, an automated workstation equipped with software and hardware, and a means of dispensing fuel from the warehouse associated with a stationary system information processing, while it is equipped with a device for automated measurement of parameters and the amount of fuel in tanks, a multimonitor system, warning devices, an interface device for measuring instruments, technological and peripheral equipment, a rolling stock identification system and a video surveillance system, while the fuel dispensing facility includes fuel dispensers dispensers with an identification device on the dispenser fuel dispensers, and the information processing system contains a fuel warehouse concentrator connected through a local network with all elements of the ACS DT.

This system is not mobile, therefore, it is not possible to install this system on vehicles equipped with technological equipment for the delivery and control of fuel.

Other systems of stationary fuel dispensers are known (see, for example: RU 2377505 C1, RU 79997 U1, RU 58213 U1, EA 201690729 A1) systems for unloading fuel from warehouses (from tanks), which are also unsuitable for installation on fuel and oil refueling vehicles.

Known fueling tank (RU 2529102 C2), containing a pipeline equipped with means for connecting to the fuel tank, means for determining the value of at least one parameter of the flow passing through the means of connection, a signal transmitter characterizing the parameter value, an electronic unit configured to receive a signal and the ability to control at least one device for regulating and / or controlling the flow depending on the signal received from the receiver. The value determination means are located at or near the fuel tank connection means.

This invention relates, to a greater extent, to a method for improving the reliability of refueling aircraft, and not to control the presence and movement of fuel. The control system lacks control of fuel in the tank, control of minimum and maximum levels, etc.

Known is an automated system for accounting for the supply of fuels and lubricants (RU 61910 U1), containing a central control device, in which microcomputers of consumers with autonomous non-volatile memory are introduced, each of which has a unique identification code and a built-in means of secure verification of the identification code, as well as protection means for non-volatile memory from writing by unauthorized data sources, and terminal devices for ensuring data exchange between consumer microcomputers with autonomous non-volatile memory and a central control device, the inputs-outputs of which are connected to the first inputs-outputs of terminal devices, the second inputs-outputs of which are connected to the inputs-outputs microcomputers of consumers with autonomous non-volatile memory, while the central control unit is made in the form of a computer and contains authorization codes for recording data into the non-volatile memory of microcomputers in memory bits with autonomous non-volatile memory and means for reading data from consumer microcomputers with autonomous non-volatile memory, and the autonomous non-volatile memory of consumer microcomputers with autonomous non-volatile memory is made with at least three regions of non-volatile memory, in which the first area is made with the possibility of one-time recording and is protected from rewriting and contains a unique identifier of the user's microcomputer, the second area is made with the ability to write and read when connected to the central control device via terminal devices for data on the consumption of fuel and lubricants of the consumer, and the third area is made with the ability to write and read information about the consumption by the consumer fuels and lubricants from computers (servers) installed at stations for the supply of fuels and lubricants.

This system, as such, does not monitor the characteristics of the fuel in the tanks, does not monitor the purity of the fuel (fuel filtration, the presence of water in the fuel). Also, the system does not have a computing part for obtaining the mass of the fuel delivered.

There is a known installation for dispensing oil products from a tanker of a tanker, containing a mechanical cleaning filter, a liquid meter, a dispensing valve, which is equipped with a gas separator, a temperature sensor, an input and display unit, a control unit, arranged in series on a pipeline for an oil product, a liquid meter is made in the form of a flow meter , comprising a measuring chamber and a sensor on the Hall element, the output of which is connected to the first input of the control unit, the second input of which is connected to the output of the specified temperature sensor, the specified dispensing valve is made in the form of an electromagnetic two-stage valve, the first and second inputs of which are connected respectively to the first and second outputs of the control unit, the other inputs of which are connected to the corresponding outputs of the input and display unit. The input and display unit, the control unit can be part of the hardware and software complex, while the specified control unit contains a PC-compatible computer with nonvolatile power supply and the function of autosaving data in case of emergency shutdown of the fuel tanker's on-board network, a GSM-GPRS terminal for providing cellular communication between the control unit and a computer of the central administrative office, a GPS navigator for determining the location of the tanker on the territory.

The main disadvantage of this installation is a small amount of processed information (in fact, only the fuel consumption and temperature): in particular, there is no control of the presence of fuel in the tank, the presence of bottom water in the fuel (and its level), there is no possibility of blocking at the maximum and minimum level, for water ...

Similar systems are known from non-patent sources.

There is a known fuel delivery control system offered by Geotek BS LLC (https://geotekbs.ru/solutions/tankertruck/).

The system controls a meter and a valve installed on the tanker. Transactions are sent to the server using the GPRS / WIFI data link. The coordinates of the filling stations are fixed using the built-in GPS / Glonass receiver. The fuel level on the tanker tank is regularly transmitted.

This system, like the previous one, is characterized by low functionality.

There is a known system for dispensing fuel on refuelers and stationary containers, offered by AITOB-Soft LLC (https://itob.ru/solutions/sistema-razdachi-topliva-na-toplivozapravshchikakh-i-statsionarnyakh-yemkosty/).

The known system operates as follows. The equipment is equipped with a fuel distribution system with an information board about the amount of fuel dispensed. A magnetic card is installed in the receiver of the fuel dispensing control panel. With its help, the driver is identified. The fuel shut-off valve, which is controlled by the on-board controller, works to dispense fuel. If, during the unloading of fuel, the system detects an excess of the set limit, the valve will automatically block the delivery of fuel. Information about all events recorded by GLONASS / GPS equipment during fuel unloading is transmitted via various communication channels: GSM, WiFi, IRIDIUM, inmarsat, to 1C software or SMS messages to mobile phones, dispatchers, security service and the management of the transport department. The processed data on the amount of fuel, the beginning and end of refueling, the recipient and the location of the vehicle are displayed in a convenient tabular and graphical form in the 1C: GLONASS / GPS Satellite Monitoring Center (1C: TsSM).

This system is aimed exclusively at controlling the fuel consumption (fuels and lubricants), while the system does not control the level in the tank, blocking the maximum and minimum levels, blocking in the presence of water in the fuel.

The automation of the refueling tanker (system for monitoring the availability and movement of fuel and lubricants), developed by OOO Lokoil, was chosen as a prototype.

The prototype system provides:

• Monitoring and control of the movement of the tanker along the routes (logistics).

• Monitoring and control of technological operations of filling, transportation, filling and discharge of liquids (economic security).

• Monitoring and control of the fuel level in the compartments.

• Monitoring and control of operating modes of tank truck devices (industrial safety).

• Automation of filling. Dosed delivery of petroleum products with the identification of the refueller or recipient. Pump control.

• Accounting for the released dose in liters and kilograms.

• Customizable reports.

• Integration with ERP systems.

The prototype system works as follows.

Instrument sensors (tank hatch position sensor, level gauge, bottom valve position sensor or air pressure sensor, oil product sensor, meter with pulse sensor), the pilot valve are connected to the MS-KVSh controller. Triggering (changing the state) of the sensors is recorded with reference to time and coordinate in the controller's log and automatically, at a specified time interval, is transmitted via the GSM (GPRS) channel to the server. The data (GPS / GLONASS coordinates) on the movement of the vehicle is also transmitted at a specified time interval. The server receives the data, processes it and stores it in the database. The server also processes requests from client workstations and returns the requested data (reports, tracks and other graphical information) to them. A WEB server is used as a user interface. After entering the login and password, the user (Administrator, Dispatcher, Economic Security Service, Industrial Security Service, Logistics) gets access to the relevant information.

For refueling vehicles at the ATZ, the MC-KVSh controller terminal is used. The terminal controller is designed to control the refueling process. In addition, the functions of controller configuration, meter adjustment, viewing the event log, identifying the refueller and the customer are available. A refueling smart card is brought to the terminal. The controller identifies the tanker and / or customer. The dispenser infuses the dose and starts refueling. An event is generated about the start of refueling. During the filling process, the controller receives data from the meter pulse sensor. At the end of refueling, the valve closes and an event is generated in the MS-KVSh controller with reference to the coordinate and time of refueling (start, end, dispensed dose) and the fuel level in the compartment. The received information is automatically transmitted via the GSM (GPRS) channel (item 2) to the server.

In this prototype system, there is virtually no quality control of the issued petroleum products (fuels and lubricants), in particular, there is no control of the presence of water in the fuel (in the tank, in the filter). There is no way to calculate the mass of the fuel dispensed No blocking in the presence of water in the fuel.

The objective of the invention was to create a system for monitoring the presence and movement of fuels and lubricants, which allows in automatic or semi-automatic mode to load fuels and lubricants and refuel vehicles with precise control (taking into account) the quantity and quality of pumped products.

EFFECT: optimization of the operation of fuel and oil refueling servants in time, delivery of fuel and lubricants in the exact amount and only of acceptable quality.
