Description

The invention relates to simulators for training traction rolling stock drivers and can be used for training locomotive drivers, as well as for use in institutes and technical schools for training students to operate safety devices, studying the composition of equipment, their design features, operating principles, and performing basic functions ensuring the safety of train traffic, studying the interaction of safety devices with infrastructure devices.

A well-known simulator is a locomotive driver (see. Railways of the world, No. 09 for 1999, F. Deloise, "The use of simulators in railway transport"). This simulator contains an interconnected instructor module, a driver’s workstation module, and modules of various systems models characterizing a particular type of locomotive, as well as train and track model modules. It is known that it is most effective to train train drivers on condition that their jobs are maximally consistent with the simulator and real traction rolling stock. It is also known that the locomotive can be equipped with various security systems. For example, it can be equipped with a speedometer (such as KPD-3 or ZSL-2M) and a continuous automatic locomotive signaling system (ALSN), or a complex safety device KLUB-U, in which the functions of ALSN and a speedometer are combined.

The closest analogue of the present invention is a simulator for training locomotive drivers (RU 105054 G09В 9/04 of 12/28/2010), containing interconnected modules of the instructor’s workstation with task selection and training control elements, indication and control elements of the driver’s actions, and also elements for simulating train radio communications, a modeling unit with modules for models of various traction rolling stock systems, trains and tracks, including a security system module, a driver’s workstation module with organs board, display elements, including a speed indicator, as well as elements of train radio simulation.

The disadvantage of this device are:

- Inability to interact with a safe locomotive integrated complex BLOCK;

- Lack of visual presentation of information about track infrastructure facilities from the driver's cab;

- The inability to form various conditions of the security system depending on the condition of the locomotive systems;

- The inability to form channels ALSN, ALS-EN and track generators SAUT;

- The inability to set the route following the actual location of the locomotive according to information from satellite navigation systems.

The technical result of the invention is to expand the functionality and provide increased training for locomotive crews and maintenance personnel associated with the conduct of the train.

Given the high cost of simulators, the training of drivers in locomotive depots, technical schools, and educational institutions in practice takes place on simulators with one of the security system options. In such cases, it is advisable to use a more promising security system, such as “Safe Locomotive Combined Complex” (BLOCK), which has more advanced functions, combining the functionality of previous generation systems, such as KPD-3, ALSN, KLUB-U, and also includes the wake-up control device of the driver TSKBM and the automatic braking system SAUT, additionally providing:

- interaction with track generators to obtain information about the route and reception of the train to the station;

- aimed braking to prevent the passage of prohibiting signals;

- the use of data obtained from satellites of the global navigation system, which ultimately will improve professionalism, reduce the cost of the simulator and the cost of the training process.

The technical result is achieved by the fact that the simulator for the training of locomotive drivers, containing an interconnected module of the instructor’s workplace with task selection and training control elements, indicators and control elements for the driver’s actions, as well as elements for simulating train radio communications, a modeling block with models for various systems traction rolling stock, trains and tracks, including a safety system module, a driver’s workstation module with controls, indication elements, including It is characterized by the speed indicator, as well as elements of train radio communication simulation, in which a simulation signal generation device is introduced into the simulation unit, and the security system model module consists of a system cabinet interconnected by an internal CAN interface, a locomotive display unit, controls, an awake control unit a driver, a removable storage medium, a matching unit with a speed sensor, and a rail signal receiving module, connected to a simulation signal generating device, to which is connected to the internal CAN interface and to the external CAN interface to which the system cabinet is connected, the instructor workstation module is equipped with a personal computer with a reader and two monitors connected to it, one of which is installed in the driver’s workstation module, the personal computer is connected to the organs task selection and learning control and is connected to the simulation signal generation device and the system cabinet of the simulation unit.

The simulator for the training of locomotive drivers and maintenance personnel works as follows.

Before the start of the study trip, the instructor turns on the simulator and, using the task selection and control bodies 16, prepares the task for the study trip, while using a personal computer 7 and a simulation signal generation device 15 sets up the simulation of locomotive movement parameters, selects a section and sets up movement simulation according to the SNA, emulation the operation of braking devices and the operation of the braking system in combination with simulated braking devices, simulating the signals of track devices and speed (not shown in Fig. 1). At the same time, the monitor 10 displays the plan of the selected route, the simulation modes of locomotive systems, the modes of operation of devices, and infrastructure. On the monitor 6 only the driver’s cab and the view from it are visualized.

The driver includes a model module for the safety device 1 and installs removable media 13, and the TSKBM 11 unit is activated. Using a control program installed on a personal computer 7, a signal is generated to turn on the EPC key (not shown in the diagram). Using controls 8, the following parameters are entered: driver number, train number, train length and mass, direction of travel, track number, sign of the correctness of the path, sets the operating mode (train, shunting, double traction), which are processed and recorded via the internal CAN- interface to the BS-DPS unit 12.

Data on pressure values generated by the simulation module of the braking devices of a personal computer 7 using a simulation signal generation device 15 is supplied via an external CAN interface to the system cabinet 5 for performing algorithms of forced auto-stop braking, targeted service braking, to implement the function of protection against unauthorized key disconnection EPA, as well as on the display unit 4 for display and removable media 13 for recording.

The signals ALSN, ALS-EN and track generators SAUT, generated by the instructor using the device for generating simulation signals 15, enter the module for receiving rail signals 14, where they are decrypted, readings of the locomotive traffic light are generated, the number of free block sections ahead of the train is determined , the target speed, the maximum permissible speed of the train on this block section, and then the data via the CAN interface internal is transmitted to the display unit 4 for display, recording on a removable carrier 13 and into the system cabinet 5 for making a final decision on the permissible target speed of movement in a given block section, for calculating the length of block sections, the permissible speed of movement in this block section, calculating data for performing targeted braking.

To begin the movement, the instructor using the device for generating simulation signals 15 generates speed signals that are transmitted via the internal CAN interface to the BS-DPS 12 unit, where they are further converted, and then to the system cabinet 5 for comparison with the permissible speed and deciding on emergency or service braking, as well as in the display unit 4 for display on removable media 13 for recording.

The instructor using the personal computer 7 forms the data of the navigation satellite system. Using the data of the motion simulation module according to the SNA of the personal computer 7 about the location of the train and in accordance with the electronic map of the section installed in the system cabinet 5, the security model module 1 determines the distance to the object ahead and the speed limit for the object to be tracked. These data are displayed on the display unit 4 and are recorded on a removable medium 13.

System cabinet 5 using the obtained data on the values of permissible and target speeds in the current block section forms the final decision on the values of these speeds, forms a curve for the reduction of speed values for various categories of trains (high-speed, passenger, freight) when approaching a forbidden traffic light or when approaching to the railway object (platform, station, arrow, level crossing, etc.) and, depending on the train situation, issues an emergency or service braking command in case of exceeding permissible speed.

The system cabinet 5 receives information from the device for generating simulation signals 15 via CAN external about the status of locomotive devices (driver's controller, compressor, typhon, whistle, electro-pneumatic braking enable circuits, panic button, etc.) digitally processes them and transfers them internally CAN interface for recording to removable media 13.

Monitor 6 provides visualization using 3D graphics, depending on the speed of the train, the following information:

- view from the driver’s cab: textured earth's surface, distinguishable landscape objects (urban and rural buildings, rivers, lakes, mountains, forests, fields, etc.), railway tracks and station buildings;

- track objects: railway track, rolling stock (locomotives, wagons), buildings, premises, kilometer, picket and terminal posts, contact wire lines, traffic lights;

- parameters of locomotive movement and brake system operation.

During the trip, the instructor, using the task selection and training control bodies 16, by changing the lights of the traffic lights, the operation of the track generators, changing the operating modes of the locomotive and the brake system, manages the training process on the simulator, including creating emergency situations, and using the monitor 6, the display unit 4 controls the actions of the driver and the condition of the simulator, using the monitor 10.

The driver controls the movement of the train using the keyboard, the mouse (not shown in Fig. 1), monitors the condition of locomotive equipment and the traveling situation using the monitor 6, controls the speed of movement, the coordinates of the location of the train, approaching the places of speed limitation using the display unit 4 .

According to the algorithm of the safety device, the driver confirms his vigilance by interacting with the controls 8 during single and periodic checks by the model module of the safety device 1.

At the end of the study trip, removable media 13 is removed and the data recorded using the reader 15 is read using software installed on a personal computer 6.

In connection with the foregoing, we can conclude that the technical result of the present invention provides enhanced functionality and enhances the training of locomotive crews and maintenance personnel with the conduct of the train, thereby reducing the psychophysiological stress of the driver in the process of human-machine interaction, identification and study contingencies and methods for solving them, and ultimately improving train safety.
