AUTOMATED TICKER-SYSTEM OF REMOTE DISPLAY OF DATA FOR LED-BOARD IN BENCH TESTS OF INTERNAL COMBUSTION ENGINE

torists compared to petrol or diesel cars. Also shown are the data of hybrid vehicles for comparison with petrol cars of the same class. Conclusions that buying a car with a hybrid power plant (HPP) is economically preferable to purchasing a similar car with a conventional ICE. However, hybrids are losing their competitive advantage due to the improved efficiency of gasoline-powered vehicles. Therefore, there is need to assess the fuel efficiency of vehicles with hybrid power plants. For evaluation of the fuel efficiency of vehicles with HPP a method is proposed of evaluating their fuel efficiency. To calculate the fuel efficiency of hybrid cars the following data are required: total mileage of the hybrid car, mileage of the hybrid car in electric mode, car mileage in hybrid mode, power consumption of the battery of a hybrid vehicle to overcome 1 km in electric mode, cost of 1 kW of stored energy in traction battery from a standard mains, fuel consumption in hybrid mode, cost of fuel. It is shown that, the less the daily mileage of a hybrid car and lower the average speed, the cheaper is the km of its run. Unlike vehicles with ICE, in which high consumption of fuel occurs on the first kilometers at low average speeds, which is associated with intensive heating up of the ICE when its temperature reaches the nominal value and with the fact that the car in traffic jams has a low average speed (up to 30 km/h), and the ICE works inefficiently. synchronized with the process of the experiment is solved by existing methods of concentration and interactive presentation of information. The purpose of this study is to develop an LED-board with an automated ticker-system for prompt display of information during bench tests of internal combustion engines. The developed design is based on the MAX7219 microcircuit. Data transfer occurs using the UART interface via the Bluetooth mod-ule HC-06. The driver is controlled via the SPI interface (mode 0). The choice of LED display is due to the possibility of using monochromatic light emitting diodes as point sources of radiation with a wide range of options for regulation of luminescence parameters. This is achieved when using high-performance LED clusters Pure-Green (525 nm), Ultra-Red (660 nm), Blue (470 nm). In the article the authors developed a constructive scheme of LED board for displaying the data of bench tests of internal combustion engines. The principle of the moving series (ticker), which is widely used in stock exchange analytics and advertis-ing, is informative enough to reproduce the results of the internal combustion engine test bench tests. It has been determined that the application of the Arduino modular system will allow to vary the properties of the data display system to a wide extent and, when developing special software, to conduct test analytics using adaptive neural networks. The method of analysis and display of bench test data of an internal combustion engine has been improved. The developed scheme can be developed for holographic illumination of critical load zones on the surface of the structure under study. The slightly lower interactivity of holograms compared to augmented reality makes their supporting role more appropriate. It can be the basis for the formation on such a surface of markers for interactive augmented reality systems.
