The Development Of Railcar Fuel Electronic Monitoring Device

The number of rail car fuel consumption is a very important indicator of whether the rail cars running mileage is in good condition or not.The majority Electrical Power in Beijing railway Deports detects and measures the railcar fuel oil consumption merely through the visual observation of the fuel level gauge or through the ground refueling system indirectly, therefore some problems are caused, such as inability to obtain the accurate railcar fuel consumption data and to offer alarms timely when the railcar consumes fuel in an abnormal way and so on. The paper introduces the research background and significance of the rail car fuel monitoring devices, analyses the research status on the basis of the monitoring and management of domestic and international fuel tectonic theory and operating characteristics of the diesel engine, the device installs transducers on the diesel engine inlet pipe and the return pipe respectively, finally This paper puts forward a photoelectric meter based on electronic fuel monitoring device research plan, and elaborates on the specific key technologies for the design, in order to calculate and record the track car fuel consumption indicators more objectively and accurately, from which can track the use of the vehicle, quality status.by judging the amount of the actual fuel consumption of the rail car.To realize the digitization of the photoelectric meter to the digital signals. the device uses Single Chip Microcomputer(SCM) to complete the data collection, Improve the electronic fuel monitor data processing ability.To realize human-computer interaction, which can display the collected flow data, the device uses the keyboard to operate the SCM, the LCD is used to display operation menu and test results.To realize alarm function, the device sets a threshold range value for the alarm function of rail car fuel consumption, by monitoring the oil spills and the rail cars quality monitoring of the rail car, the device can remind watch keeper the in time by using sound and light alarm prompt avoid fuel waste of resources and the occurrence of fire.In the whole system function realization aspects, after the loading test of the device in nearly a year in a rail car depot of the Beijing bureau, the function of the with a large number of statistical and validation experiments of entire system realization, Experimental rail car passed the investigation during a period of repair period. Finally, the experiments confirmed that the monitoring device is feasible, moreover, it has three good practicalities: the accuracy in internal combustion car consumption statistics and management, the oil spills security tips for rail car rail car and provide rail car quality prompt of the rail car. The analysis and conclusions of the paper has a certain reference on the theory and practice of the rail car fuel monitoring device.
