The disadvantages of the above known simulators and training systems is the low quality of training of railway workers.

The claimed complex of software and hardware - the train operator’s simulator is designed to organize training of personnel in order to increase their knowledge, acquire skills in the operation and maintenance of railway equipment, organize actions in emergency and emergency situations, to eliminate the psychological barrier when working with new automation tools .

The technical result is an increase in the efficiency and quality of training for railway workers, while reducing the likelihood of erroneous actions by operators in real situations by developing the skill of analyzing the situation, performing the necessary sequence of actions to manage equipment, and increasing the psychological stability of personnel during training on the simulator under conditions of simulating critical situations.

When organizing the simulator, one of the main approaches is the use of standard devices and their automatic control systems, which do not include additional elements and nodes other than those used on a real object.

All technical solutions required to ensure staff training should be implemented using software and hardware included in the simulator.

For simulators of operators who manage objects on the railway, the most significant and expensive is a system for simulating the visual environment and modeling the audio effects that arise during the operation of the control object, which is very important for creating a reality effect during training.

The claimed simulator works on the basis of a three-dimensional virtual model of the real world, and does not use pre-recorded video. This allows you to ensure the correct dynamics of the train, the correct operation of the brake system, smooth starting and stopping, switching arrows, traffic lights. The software allows you to connect real and virtual blocks and units of a simulated locomotive to the simulator, which allows you to simulate technical equipment malfunctions and teach how to solve them.

The train simulator of the railway equipment operator is made in the form of a locomotive cabin equipped with a camera for the possibility of monitoring the tested railway equipment operators, a module for simulating sound signals, a device that reads psychophysiological readings from the railway equipment operator, a railway equipment operator workstation consisting of a control panel with buttons, levers , joysticks, indication lamps, LEDs, for the possibility of imitating external actions in places of side windows large-format displays are mounted on which an imitation of the rail track is displayed, as well as a 3D image of the hydraulic mechanisms of railway equipment, a three-dimensional touch screen is placed on the windshield, which is equipped with a tactile feedback system and to which a manipulator arm is connected, capable of transmitting tactile sensations from virtual objects to the operator of railway equipment, a joystick for moving, a head position tracker and a headset for radio communications, while the three-dimensional touch screen provides Chiva three-dimensional virtual model of the real world, and is configured to output a three-dimensional image of circuits, systems and railway engineering units, as well as generating information on the found faults in them.

Thanks to 3D technology, a complete simulation of movement along the rail track has been created, the operator can see the condition of the rail, as well as the readings of all instruments, and the actions of the mechanisms of railway equipment, and based on this make a decision on the further progress of the work. For the training of operators, scenarios are laid where deviations from the nominal readings can be not only fixed on certain sections of the track, but also have a random character, so that it is possible to bring the operator's actions to automaticity. All actions of the operator during the trip for the simulator are recorded, audio conversations are recorded and the actions of the subject are recorded.

In the simulator can be laid as an abstract section of the path, and a real section with its own characteristics. 3D-based imaging technology has created a realistic picture of what is happening and achieved the effect of presence. Additionally, for realism, the sounds of work on real railway equipment are recreated. Also, a complex physical model is laid inside the simulator software, which makes it possible to make all ongoing processes look like real ones. The railway equipment inside the program was recreated according to electrical, hydraulic and pneumatic schemes. All processes occurring in it in the process of work are simulated. Thanks to this, an imitation of real breakdowns and equipment failures is made.

The user can feel with his fingers the objects that he sees on the screen, using a special manipulator arm that moves the screen back and forth. The transfer of tactile sensations from virtual objects is achieved by moving the screen. The objects themselves can be touched (display movements convey the shape and size) and moved with your fingers (the mass of the object is also transmitted here). The software of the workplace allows you to: move along the cars at the station (joystick), inspect the cars “on the move” for car malfunctions, inspect the cars in the train before departure for malfunctions, test the brakes in the train in accordance with the instructions, fill out the certificate forms of VU-45, to conduct negotiations on radio communications, and inspection of wagons is carried out in a 3D scene.

The touch screen with a three-dimensional image of the body of the electric locomotive with the equipment located in it allows you to virtually make the necessary switches to troubleshoot or collect emergency circuits using controls located on the blocks and panels in the body of the electric locomotive.

The graphic capabilities of this training complex allow you to create any possible malfunctions and their visible manifestations, both in your train and in oncoming trains. It is mandatory to reproduce various malfunctions of the path, the contact network, violation of the size, etc. The software allows you to practice and control the learner's actions in the order of assisting a stopped train using an auxiliary locomotive. To reproduce the mode of shunting movements around the station, starting from the departure from the depot (PTOL) to the hitching of the locomotive to the train and much more.

A panel of electrical measuring instruments is displayed on the screen (pressure gauges for measuring fuel oil pressure, a tachometer for measuring the crankshaft speed, an ammeter and a voltmeter for measuring current and voltage of the traction generator), which control the values of the state parameters of diesel equipment during operation with electric scheme. Deep simulation of the logic of the safety devices, electrical and pneumatic circuits, physical processes of the train. During the training process, all parameters of the rolling stock and the driver’s actions are recorded in a special trip analysis program.

For each rolling stock car, a detailed calculation of the state of electrical and pneumatic circuits and their components, such as air distributors, engine cranes, pneumatic relays, tanks, contactors, switches, power units, is carried out. A training route is created based on a real path profile. To create it, real data from railroad terro-stations are used. The video sequence is a traced station in 3D graphics with railway objects, namely, they draw all the main and side tracks of the station, the surrounding landscape to the level of recognition of all the main objects located within sight of the locomotive’s cab, the location of all outdoor devices at the station and section (traffic lights, arrows , congresses, signs, shields, crossings, supports of the contact network, pickets, etc.). The change in the position of objects in the scene is synchronously transmitted to all workplaces using 3D graphics, the sounds and noises characteristic of a real trip in the simulator cabin are simulated by a module for simulating sound signals, reproduced using sound speakers. Due to the fact that the simulator is made using 3D technology, it is possible to create a picture close to the real one on the screens simulating the outside world. There is a smooth change of day and night, it is possible to set a trip at any time of the year and under any weather conditions.

The illusion of a real trip during a training exercise is also enhanced by creating a real acoustic environment, by simulating the noise of the equipment.

At the same time, the simulator is made with the ability to connect to the module of the instructor’s workstation, equipped with software and consisting of a server, a monitor for monitoring the actions of the railway worker, a monitor for setting the script, non-standard situations containing various malfunctions at the nodes of the train or railway, using a computer network.

In the server of the instructor’s workstation module, the software “Virtual World Server”, “Instructor”, and decryption data for saving test trips are used as software.

The psychophysiological state of the subject is recorded by the device during the creation of various emergency situations, i.e. a person’s reaction to arising malfunctions during the journey, in order to enable the subject to familiarize himself later and analyze his mistakes, so as not to allow them in the future.

The video surveillance system allows you to record video from cameras for subsequent analysis of the actions of the subject. To coordinate the actions of participants, a server is installed.

After each virtual trip of the test subject, the instructor has the opportunity to print a report with all the errors of the driver and if there are too many of them, you will have to repeat the race.

In the claimed simulator, it is possible to select not only the time of day, time of year, rainfall intensity, but also provides the ability to select the ambient temperature. In this case, the simulator program itself will change the coefficient of adhesion of the wheel to the rail, the conditions for the visibility of the signals will change, and in addition to everything, the operation of the train brakes will change, especially at low temperatures. The calculation of the model of air behavior in the pneumatic system allows you to simulate the actual passage of air through the system of the whole composition, the operation of valves, valves (including animation of this work, in which channels air will pass and with what pressure), the creation of leaks in separate places affecting the entire composition , and also to monitor the behavior of the pneumatic system on long trains, etc.

Abnormal situations can be represented as:

- obstacles on the way (vehicle on the move, rolling stock off the rail);

- malfunctions in the operation of a continuous automatic locomotive signaling system (ALSN) (blocking the allowing indication of a traffic light to prohibit, loss of codes, tracing of an extinguished traffic light, total about 20), in turn, ALSN can be implemented in various versions: typical ALSN, ALSN with preliminary light signaling, ALSN with a device for monitoring the vigilance of the UKBM driver, etc., while the same drivers can travel on locomotives of the same type equipped with various security systems;

- violation of the normal operation of the auto-brakes of the rolling stock (malfunctions of the auto-braking equipment, failure to release the brakes, closing of the end crane, about 20 in total);

- emergency situations when sending / arriving at the station (departure / arrival at the prohibitory indication of the traffic light, departure at the yellow signal of the traffic light, other);

- following with a train at night;

- following with a train in conditions of poor visibility: fog; rain; snow.
