Description

The invention relates to measurements, in particular to automated systems for monitoring and recording fuel consumption of special self-propelled rolling stock (SSPS) of railway transport.

It is known to install two OR-40 type flow meters into the fuel system of a 2-2D49 diesel locomotive, one on the discharge line, the other on the discharge line. The difference in the readings of these flow meters is the amount of fuel consumed by the diesel engine. The role of the computer is performed by the MS-75 device, which measures, records and remembers the total volume of fuel passing through the flow meter. In addition, the MS-75 device also allows you to determine the difference in volumes and flow rates of two primary converters, flow rate, operating time and experiment time. The MS-75 device has a port for connecting a computer (reading device) - (article in the journal “Heavy Engineering No. 7, 1999, V.V. Domogatsky, V.Z. Kakotkin, L.S. Turov “Universal wide-range exemplary roller blade flow meters and liquid and gas quantity meters) - analogue.

The disadvantage of the known solution is that during the process of refueling fuel tanks or repairing the diesel fuel system, water and air may enter the fuel system.

A device for measuring diesel fuel consumption is known, which includes a recording device that performs the function of collecting data from sensors and fuel level sensors installed in the diesel fuel system (utility model patent RU 119100 U1, IPC: G01F 9/00, published 10.08. 2012) - prototype.

A disadvantage of the known solution adopted for the prototype is the possibility of water and air entering the fuel system during the process of refueling fuel tanks or repairing the fuel system of an internal combustion engine. In the known solution, when measuring fuel consumption, the possible presence of water and air in the supplied fuel is not taken into account, the presence of which leads to a decrease in the accuracy of fuel consumption measurement. The absence of devices for removing water from fuel increases the likelihood of failure of the fuel equipment of an internal combustion engine.

The technical result to be achieved by the claimed solution is to increase the reliability, accuracy and controllability of the measurements taken by the device, as well as to increase the reliability of the fuel equipment of the internal combustion engine of special self-propelled rolling stock by minimizing the presence of water and air in the fuel.

The specified technical result is achieved by the fact that the device for monitoring fuel consumption of special self-propelled rolling stock contains an electronic computing unit with inputs connected to the outputs of fuel level sensors in the fuel tank, flow meters, an auxiliary device sensor and a transmitting antenna, one flow meter is installed on the fuel supply pipeline to the engine, the second - on the pipeline for draining excess fuel from the engine into the fuel tank, and the input of the flow meter installed on the fuel supply pipeline to the engine is connected to the outlet of the filter-moisture separator, and the input of the flow meter installed on the pipeline for draining excess fuel from the engine to the fuel tank is connected to the outlet of the deaerator .

The claimed solution is specified in Fig. 1, where its block diagram is presented.

For the purposes of this application, JSCS refers to special self-propelled rolling stock in accordance with clause 2 of Order No. 2676r dated December 26, 2016 “On the approval and implementation of the rules for the operation of special rolling stock on the infrastructure of JSC Russian Railways” https://rulaws.ru /acts/Rasporyazhenie-OAO-RZHD-ot-26.12.2016-N-2676/.

The fuel consumption monitoring device consists of capacitive type fuel level sensors 1 and 2, located in the fuel tank of a special self-propelled rolling stock (SSPS). Signals from the sensors are transmitted to the electronic computing unit 3. Fuel consumption by the engine of a special self-propelled rolling stock is estimated by the electronic computing unit 3 based on data from flow meters 4 and 5. In this case, flow meter 4 is installed on the fuel supply pipeline to the engine, and flow meter 5 is installed on the excess fuel drain pipeline from the engine to the fuel tank. In order to clean the fuel from water, a filter-moisture separator 6 is installed in front of the flow meter 4. To remove air from the fuel system, an automatic deaerator 7 is mounted in front of the flow meter 5. Monitoring of the operating mode of the engine of special self-propelled rolling stock (SSPS), for example, a track machine, is carried out by an electronic unit based on a signal from sensor 8 of the operation of the auxiliary devices of the track machine. The location of the JOSS system is monitored by an electronic unit using a signal from transmitting antenna 9 (for example, GLONASS or GPS). The stored data is transmitted wirelessly to the operator’s computer and entered into its database for subsequent analysis and processing.

The placement of the filter-moisture separator 6 in front of the flow meter 4 installed on the fuel supply pipeline to the engine, and the deaerator 7 in front of the flow meter 5 installed on the pipeline for draining excess fuel from the engine into the fuel tank is due to the need to first remove water and air from the fuel to increase the accuracy of subsequent fuel consumption measurements flow meters 4 and 5.

The functional placement of the filter-moisture separator and deaerator, in the specified places, in conjunction with all other features of the independent claim of the formula, ensures the achievement of the claimed technical result, which is achieved due to the fact that the SSPS fuel consumption monitoring device, which includes an electronic computing unit, configured to collecting, analyzing data from the device nodes and transmitting them to the operator’s computer, an antenna connected to it with the possibility of wireless data transmission, a sensor for the operation of auxiliary devices of the JSPS, fuel flow meters with the possibility of installing them in the fuel system of the JSPS, fuel level sensors with the possibility of installing them in the fuel the SSPS tank, a filter-moisture separator installed in front of the fuel flow meter at the inlet to the SSPS internal combustion engine along the fuel flow and a deaerator installed in front of the flow meter of excess fuel coming from the SSPS internal combustion engine into the fuel tank along the fuel flow.

The proposed solution allows us to minimize the impact of the operation of the JSPS systems, which negatively affects both the operation of flow meters when measuring fuel consumption, and the operation of the fuel system of the internal combustion engine of the JSPS.

In the proposed solution, before measurements carried out by fuel flow meters, the fuel is cleared of water and air, the accuracy of fuel consumption measurement is increased, and comparison with data from fuel level sensors in fuel tanks allows further increasing the accuracy of fuel consumption control. Collecting data on fuel consumption from sensors by an electronic computing unit and transmitting them via wireless communication to a computer allows them to be quickly analyzed by the operator.

This ensures the minimization of the presence of water and air in the fuel when measuring its consumption, and, consequently, high accuracy, reliability and controllability of fuel consumption measurements carried out by the SSPS fuel consumption monitoring device.
