Description

The invention is intended to control the consumption of fuel, fuels and lubricants (fuels and lubricants) without the use of expensive flow meters and can be used in energy systems with diesel engines of vehicles, as well as in diesel pump units. It is especially relevant for monitoring fuel consumption on marine engines, diesel engines with large diesel engines from 50 kW and more, when there are systems of shale water, where in the manual mode for unauthorized withdrawal they can use "WALL" and "DRAIN" fuel.

A known metering system for the fuel consumption of internal combustion engines of a vehicle (hereinafter - TS), containing two flow converters, two thermometers on the discharge and drain pipelines, a computer from the controller, display panel, archive, real time clock, port, two pulse shapers associated with flow converters and calculator (see RF patent for utility model 24555, IPC G01F 9/00, 1/10, published on 08/10/02.). To more accurately account for the flow rate, a flow stabilizer was introduced into the system design and the processing scheme of the received data was complicated, however, the system does not exclude the possibility of unauthorized fuel extraction. The disadvantage of the system is the measurement of fuel consumption by flow meters, which are expensive, inaccurate, do not provide a measurement of fuel consumption depending on the work performed by the engine.

A device for monitoring and recording fuel consumption on a vehicle using fuel consumption sensors, including a transmitting device and an antenna, a fuel control device is made in the form of a drive module with a computer module for receiving, preprocessing and transmitting information about the amount of fuel, a peripheral device board. The device is equipped with protection against unauthorized opening of the fuel control device in the form of a limit switch (see application for invention 2012128377, IPC G07C 5/00, published January 20, 2014. - RF patent 2505861). Peripherals include a GSM / GPRS modem, a GPS receiver. At the same time, despite the availability of anti-vandal funds, unauthorized removal of fuel is possible without establishing the true fuel consumption spent on the work.

A device for remote monitoring TC is known, which contains a GPS navigation module, a control module, the input of which is connected to a GPS module, and the output to a GSM module, a processor unit with the ability to connect its input terminals to the vehicle diagnostic line, to the nozzle and fuel level sensor and the output terminals of the processor unit provide the output of the processed signal from the fuel level sensor, the output of the engine operation indicator signal, the FMS bus signal output, the fuel consumption signal output in rotary format Domer and service output (RF patent for utility model 85 678 "Device for remote control of the vehicle," the IPC G01S 15/14, published 10.08.09.). The GPS module determines the vehicle coordinates according to the commands of the control module, the GSM module sends messages with the vehicle identifier, its coordinates and service information. On the subscriber's computer, in relation to the geographical map, the TC driving route, stops, high-speed mode, etc., are recorded, the fuel consumption taken by the flow meter from the injector nozzle. After the computer processes the signal from the standard sensor, a signal is output to the normalized fuel level output. It is indicated that the output of the engine operation indicator signal provides information for the analysis of unauthorized fuel consumption using a rotary flow meter. This allows you to calculate the required amount of fuel to the existing flow rate so that the TC is at a certain point in the route. The disadvantage of this device is the control of fuel consumption according to the flow meter, which does not allow to detect unauthorized removal of fuel when the engine is on. In addition, the equipment used is extremely unreliable in terms of organizing the disposal of fuel and lubricants and is expensive to operate.

A known system for monitoring fuel consumption of a vehicle comprising a fuel level sensor connected to an on-board network TC, a sensor for engine speed, speed, and are electrically connected to the registration unit. The registration unit contains a microcontroller, a real-time clock, an archive, a port for displaying information from the archive and entering parameters (RF patent for utility model 62235, IPC G01F 9/00, B64D 37/00, published 03/27/07.). The system is equipped with a receiving antenna, the registration unit is equipped with an additional input, a second archive, a GPS receiver for establishing the location of TC and GPRS signals or a modem for communication, the microcontroller is made in the form of a microcomputer with software, with the ability to receive the code of an external device - computer of the enterprise ACS server an external device (central server) and transmitting encoded information to it in real time or from archives. The microcontroller software implements the ability to write information in parallel to archives in the same time scale. Archives record information from the fuel level sensor and events: engine start, movement, fuel drain and geographical coordinates of the place where the events took place. The computer control system is made with the display of the operating modes TC on the graph of changes in fuel level. ACS computer software provides information reading from the 2nd archive via GPRS or modem. The signals from the terminals of the generator, tachograph, or speedometer are used as signals from the revolution sensors. The control of true fuel consumption in relation to the number of engine revolutions is more real, but it is not effective enough, because engine operation does not fully reflect the total consumption of fuels and lubricants (hereinafter referred to as fuels and lubricants) in relation to the operation of the vehicle. In this solution, the diesel rotation speed is measured without taking into account gearboxes; diesel can idle without producing any useful work.

Known RF patent No. 2361278 "System for remote control of fuel consumption and operating modes of a vehicle", IPC G07C 5/00, published July 10, 2009. In this system, the amount of fuel is measured in relation to the engine operating modes, for which a large number of different sensors of engine operation parameters are used. The operation of the system is based on measuring the current amount of fuel in a fuel tank with temperature correction while recording and archiving the engine’s step-by-step operation. The system consists of a unit for processing and archiving fuel consumption, speed, engine speed and data of other sensors, a unit for collecting data and transmitting wirelessly to the center for receiving and processing information. The system is complex, and therefore not reliable, and at the same time does not reflect the true consumption of fuel and lubricants, such an engine operation mode is possible, for example, idle mode, in which the number of revolutions will be high, but the actual fuel consumption will be insignificant, which will allow to drain unspent fuel.

The closest analogue is the system according to the patent of the Russian Federation No. 62235.

The objective of the invention is the elimination of unauthorized removal of fuel, with the simplicity of the design of the system and its high reliability.

The technical result is the ability to establish the true fuel consumption spent on the performance of the useful work of the vehicle engine with a load, without using indirect parameters that do not affect the performance of the useful work, by measuring the speed of the load shaft.

The problem is solved and the technical result is achieved by the fuel and lubricant consumption monitoring system of the vehicle, including fuel, including a speed sensor, electrically connected to the controller, including the first archive - the first database. The system also contains a navigation module for monitoring the vehicle, a central server - a server of the vehicle enterprise with communication with the controller, and means for transmitting to the central server in real time or from archives data on the location and operation parameters of the vehicle, the second archive contains a second database, archives are equipped with ports for information output. The controller software implements the ability to write information in parallel to archives in the same time scale.

Differences of the proposed system from the closest analogue is:

- connecting the speed sensor directly to the engine helical shaft after the engine gearbox,

- the introduction of an additional server - a hardware-software complex for storing, summing and processing data from the controller, for storing and editing reference information, for storing algorithms for calculating fuel and lubricants depending on the speed of the screw shaft, calculating the true fuel consumption depending on the work done by the screw (hereinafter - counter server),

- the first archive is made with the possibility of storing electronic data on the speed of the screw shaft,

- the second archive is made with the possibility of storing electronic data on the passport consumption rates of fuels and lubricants, including fuel, depending on the number of revolutions of the propeller shaft for the used engine type paired with the propeller type used for the type of ship used,

- the system is equipped with programs for processing the information received in the controller and on the servers.

It is known that in a similar system, in accordance with RF patent No. 2361278, the engine speed sensor (tachometer sensor) determines whether the vehicle is in motion to establish whether the engine shaft speed matches the fuel consumption rate, however, according to the engine speed sensor, it is impossible to determine whether this the vehicle is in motion or stands with the engine running for a long time.

In addition, from the RF patent for utility model 85678, a device for remote monitoring of a vehicle is known, in which, after the computer processes the signal from the standard sensor, a signal is output to the normalized fuel level output. It is indicated that the signal output of the engine operation indicator allows you to obtain information for the analysis of unauthorized fuel consumption using a rotary flow meter, but the mechanism for setting the fuel consumption to the normalized level is not indicated.

The drawing shows a system for controlling the consumption of fuels and lubricants / diesel fuel of two engines installed on a ship. The scheme for controlling fuel consumption for one engine or for the number of engines more than two is constructed in a similar way.

The fuel consumption monitoring system is installed on board the ship. The central server is installed on the ship or in the office of the ship company, as shown in the drawing.

The system in the version for ships contains two engines 1, after the gears 2 of which sensors of 3 revolutions in any design, for example optical, are installed on the shafts of the screws. Each sensor 3 is designed to read the revolutions of the gross line of the screw and mounted on a protective casing.

The system also contains a controller 4 for each sensor 3, which is designed to summarize, store, and transmit to the server counter 5 the readings of each sensor 3. Controller 4 in a specific embodiment is made in the form of an SKRT-31 terminal manufactured by the Technoton joint venture, which is designed to monitor vehicles and transmitting to the server in real time data on the location and operation parameters of the vehicle. The choice of the indicated terminal is convenient in that its GPS tracker is equipped with a built-in fuel consumption control function and has the minimum required set of inputs, which allows organizing effective vehicle control. Data is transferred from controller 4 to server counter 5 using any available communication channel, wired or wireless.

Counter server 5 is installed on the vessel and is a hardware-software complex with an archive (database). The output of the counter server 5 is connected to the navigation module - a mobile terminal 6 for monitoring moving objects in real time (hereinafter referred to as the monitoring terminal), which is also installed on the vessel. As a monitoring terminal 6, the MT Skat device manufactured by Monitoring Systems LLC, St. Petersburg, Russia, was used. Skat has a software platform for satellite monitoring of vehicles, fully web-based; does not require software installation on the user's computer, except for the client part. Monitoring terminal 6 is connected to the central server 7 of the ship company for sending information to the dispatcher’s console, for which it is equipped with GPRS 8 antennas for generating information from installed sensors and GSM 9 using the Internet.

The central server 7 is installed on the ship or in the office of the ship company, equipped with software for collecting, processing and subsequent analysis of all received system information, including spent fuel, to establish its compliance with the work done by the engines.

The fuel consumption control system, in particular fuel, operates as follows.

Sensors 3 revolutions of the gross line of the propellers of the engines of the vessel 1, regardless of the operation of the engines and their mode, constantly supply the corresponding signals to their controllers 4. If the engine is idling without doing any work, the sensors 3 revolutions of the shaft of the idle propellers give the controller no rotations . In each controller 4, in accordance with the established programs, the readings of its sensor 3 are summarized, the received data is saved to the archive and transferred to the counter server 5 in real time. The controller directly processes the information, including filtering and normalizing parameters, detecting events, maintaining RPM sensors.

Counter server 5, receiving data from controllers 4, summarizes data from all sensors 3, saves them; in the database (archive) of the counter server 5 information is stored regarding the passport data of nomograms of the used engine type with the type of propeller used for the vessel, in respect of which the fuel consumption is monitored. The program installed on counter server 5 contains an algorithm for calculating fuel depending on engine speed with load using passport data of nomograms stored in the database of counter server 5 in electronic form. Counter Server 5 processes the received data, stores it, edits reference information about motor ships, data on fuel consumption nomograms of all used engines of all ships of the ship’s company, numbers and parameters of installed sensors 3, numbers and parameters of controllers 4.

The output of the counter server 5 is connected to the Skat navigation module 6, which is also installed on the vessel and which constantly determines the position of the vessel by recording the time and its route, for which it is equipped with a GPS receiver that receives signals from the orbiting satellites of the navigation system to obtain the coordinates of its location in real time scale (not shown in the drawing). Additionally, with the coordinates being recorded, monitoring terminal 4 records the received parameters of the vessel from the counter server 5 in relation to the time of the received coordinates of the vessel, provides the possibility of entering reference information on ships, sensors, controllers, communication channels, etc. A software platform for satellite monitoring is installed in Skat transport, fully web-oriented, which does not require software installation on the user's computer, except for the client part. Conveniently scalable graphs allow you to visually analyze fuel consumption. Monitoring terminal 6 is configured to generate reports on fuel consumption in various sections provided with software. It is possible to adapt reports and their appearance depending on the requirements of the user. Monitoring terminal 6 is equipped with software that, in combination with the specified equipment, provides the standard functions of fixing the movement and parking, determining the speed of the vessel, movement zones, data supply voltages, as well as additional functions to determine the fuel level of one engine, its consumption and total fuel consumption by all engines, tachometer data, temperature. Monitoring terminal 6 transmits data to the central server 7 of the ship's company for further processing and analysis and sending it to the dispatcher’s console, for which it is equipped with GPRS 5 antennas for generating information from additionally installed sensors and GSM 6 using the Internet. If necessary, measures are taken against violation of the fuel consumption regime not related to the operation of engine screws.

Thus, the fuel consumption monitoring system allows you to link it (flow) with the work done by the propellers of marine engines, allowing you to identify unauthorized drainage of fuel. The ability to control unauthorized fuel extraction eliminates offenses.
