Description

The invention relates to systems for teaching the management of railway transport and can be applied in the transport industry.

As a prototype, a procedural simulator was chosen for training the driver to work with the rolling stock brake system, containing a means for displaying graphic data of the driver’s workplace with brake system controls, elements of the brake system and a central control device configured to record data obtained in the process of interaction between the driver and the brake system. brake system controls, and with the ability to display this data [RU89268U1, publication date: 11/27/2009, IPC: G09B 9/04].

The disadvantage of the prototype is the impossibility of detecting errors made by the driver in the process of teaching him to work with the brake system of the rolling stock, due to the fact that the central control device is unable to analyze the data coming from the controls in the process of passing the training scenario by the driver and subsequently identifying among them values that go beyond boundary ranges, or exceeding the established norms, which does not allow fixing violations in the actions of the driver in the process of passing the training scenario and, as a result, not only does not allow the driver to correct his actions in the process of learning how to work with the brake system of the rolling stock for further successful completion of the training scenario, but also complicates the process of analyzing the errors of the driver by the instructor after the driver has passed the training scenario, which significantly narrows the functionality of the procedural simulator for training the driver.

The technical problem to be solved by the invention is to expand the functionality of the procedural simulator for training the driver to work with the rolling stock brake system.

The technical result, to which the invention is directed, is to enable the central control device to detect errors made by the driver in the process of interacting with the brake system controls of the procedural simulator for teaching the driver to work with the brake system of the rolling stock.

The essence of the invention is as follows.

The procedural simulator for training the driver to work with the brake system of the rolling stock contains a means for displaying graphic data of the instructor's workplace, a means for displaying graphic data of the driver's workplace, brake system controls, elements of the brake system and a central control device configured to record data obtained in the process interaction of the driver with the controls of the brake system. Unlike the prototype, the central control device contains a driver error recognition unit configured to stop recording and save data obtained during the interaction of the driver with the brake system controls when the driver makes mistakes, and the procedural simulator is configured to display these data through one of the display means graphic data.

The procedural simulator for training the driver to work with the brake system of the rolling stock contains the workplaces of the instructor and the driver, equipped with means for displaying graphic data. The means for displaying graphic data can be made in the form of one or more monitors, projectors or projection screens and connected to a central control device. Also, the procedural simulator contains elements of the braking system, which can be made in the form of three-dimensional models of rolling stock braking devices.

The tool for displaying graphical data of the instructor's workplace provides display of data on the passage of the training scenario by the machinist and other data. The means for displaying graphical data of the instructor's workplace may contain means for inputting training scenarios, which may be represented by a set of function buttons and/or a screen, including a touch screen.

The tool for displaying graphical data of the driver's workplace provides the display of the road situation in accordance with the training scenario.

The rolling stock braking system controls provide the ability to generate control signals and send them to the central control device. The brake system controls are connected to a central control unit. Brake system controls can be represented by controllers, taps, levers, buttons and pedals. Controls may include, for example, a driver's valve, an auxiliary brake valve, an emergency brake valve, brake interlocks, air distributor switches, an electro-pneumatic auto-stop valve, and other devices.

The controls are equipped with control devices that provide receiving and sending to the central control device data on the activation by the driver of certain controls of the brake system. Control devices can be represented by sensors and/or electronic measuring devices, such as angle sensors, etc.

The means for displaying graphic data are also configured to display data on errors made by the driver in the process of his interaction with the rolling stock brake system controls.

Elements of the brake system provide a demonstration of the operation of the brake equipment of the rolling stock and can be presented in the form of three-dimensional models of the brake equipment of the traction rolling stock and/or freight car. Models of elements of the brake system of traction rolling stock may include the main and spare reservoirs, the reservoir of the pressure switch, the reservoir of control circuits, various valves, air distributors, driver's taps, brake cylinder and air ducts. Layouts of elements of the brake system of a freight car may include a spare tank, a brake cylinder, various air distributors, as well as a release and end valves. Elements of the brake system can be equipped with light indicators connected to the central control device and simulating the propagation of an air wave inside the elements of the brake system of the rolling stock. Also, the elements of the brake system can be equipped with elements that control the movement of the rods of the brake cylinders to demonstrate their work in the process of training the driver to work with the brake system, which can be represented by servo drives or electromagnets.

The central control device controls the elements of the brake system and records data from the brake system controls and from control devices obtained in the process of interaction between the driver and the brake system controls, as well as the selection of a training scenario. The control of the elements of the brake system can be implemented by processing the processor of the central control unit of the signals coming from the controls of the brake system and the formation of control actions on the elements of the brake system to simulate the propagation of an air wave inside them and demonstrate the operation of the brake cylinders due to the movement of the rods. The choice of the training scenario can be implemented due to the processing by the processor of the central control unit of the signals coming from the input means when the instructor selects the training scenarios.

Also, the central control device provides simulation of the road situation in accordance with the training scenario and the construction of graphs of the processes occurring in the brake system based on the data obtained during the interaction of the driver with the brake system controls, and can be equipped for this with a simulation unit.

The central control device is equipped with a driver's error recognition unit, which detects the driver's errors based on data received in the process of interacting with the brake system controls, stops data recording in the event of an error, saves this data and sends signals to one of the means of displaying graphic data to display data about the detected error.

The central control device can be made in the form of a microprocessor controller with software pre-installed in its memory. The simulation block and the driver's error recognition block can be represented as logical functional blocks integrated into the microprocessor controller. Also, the central control device may contain databases used by the microprocessor controller to store software and training scripts.

Detection of the commission of errors of machinists by the central control device can be implemented as follows.

The data received by the control devices during the interaction of the driver with the brake system controls are recorded by the central control device. Among these data there are data on the use of the brake system controls by the driver, which are compared with the established norms on the controls required at one time or another during the training scenario, and thus the correctness of the control of the brake system controls by the driver during the training scenario is checked.

The norms about the controls required at one time or another during the passage of the training scenario can be represented in the form of error fixation conditions, the coincidence with which is checked by the error recognition block in the process of data comparison.

If matches are found with the error fixation conditions during the data comparison process, the error recognition block fixes the error, and also determines its type in accordance with the condition or group of conditions with which a match was found. The error latching conditions, as well as the types of errors corresponding to these conditions, can be presented in the form of tables stored in the memory of the central control unit. When an error is detected, the driver's error recognition block stops data recording by the central control unit. To save data by the driver's error recognition unit, signals can be sent to the simulation unit to form a graph of the processes occurring in the brake system until the data recording is stopped.

After saving the data, the error recognition unit sends signals to one of the graphic data display means to display data about the detected error, as well as to display the graphs generated by the simulation unit.

Additionally, to expand the functionality of the procedural simulator, the central control device can be configured to set brake system faults. To this end, the learning scenario input means may be configured to input faults, which may be stored in databases used by the microprocessor controller. Brake system failures can be presented as an algorithm integrated into the training scenario, and simulating the occurrence of certain braking system failures in the process of passing the training scenario by the driver.

The invention can be made from known materials using known means, which indicates its compliance with the criterion of patentability "industrial applicability".

The invention is characterized by a set of essential features previously unknown from the prior art, characterized in that the central control device contains a driver error recognition unit configured to stop recording and save data obtained during the interaction of the driver with the brake system controls when the driver makes mistakes, and the procedural simulator configured to display this data by means of one of the graphic data display means.

The set of essential features of the invention makes it possible for the central control device to recognize the errors of the driver when interacting with the brake system controls and allows you to evaluate the correctness of the actions of the driver in the process of passing through the training scenario, and also allows the driver to study in detail the processes occurring in the brake system of the rolling stock if he commits errors, and if necessary, correct further actions in the process of its interaction with the brake system controls when teaching it to work with the rolling stock brake system.

This ensures the achievement of the technical result, which consists in enabling the central control device to detect errors made by the driver in the process of interacting with the controls of the brake system of the procedural simulator for teaching the driver to work with the brake system of the rolling stock, thereby expanding the functionality of the procedural simulator for training the driver working with the brake system of the rolling stock.

The invention has a set of essential features previously unknown from the prior art, which indicates its compliance with the criterion of patentability "novelty".

From the prior art, a procedural simulator is known for teaching the driver to work with the brake system, in which the central control device records data obtained during the interaction of the driver with the brake system controls.

However, a procedural simulator is not known from the prior art, with a block for recognizing driver errors, which, upon detection of driver errors, registers and stores data obtained during the interaction of the driver with the brake system controls.

In view of this, the invention meets the criterion of patentability "inventive step".

In order to illustrate the possibility of implementation and a better understanding of the essence of the invention, an embodiment of its implementation is presented below, which can be modified or supplemented in any way, while the present invention is in no way limited to the presented embodiment.

The functional diagram of the procedural simulator for training the driver to work with the brake system of the rolling stock contains:

Central control device 100, containing a central processor, and equipped with a simulation unit 101, a driver error recognition unit 102, a software base for training scenarios; means 120 for displaying graphical data of the instructor's workplace, represented as a computer monitor and provided with script input means 121, presented as a software application window; means 130 for displaying graphic data of the driver's workplace, presented in the form of a widescreen monitor, brake system controls 140; a complex of brake devices 150 containing brake devices 151 of traction rolling stock and brake devices 152 of a freight car; control devices 160, presented in the form of sensors for engaging the controls of the brake system.

Means for displaying graphic data, brake system controls, a set of brake devices and control devices are connected to the central control device 100.

The simulation unit 101, the driver error recognition unit 102, and the training scenario software base are connected to the central control unit 100.

Script input means 121 are connected to the means 120 for displaying graphical data of the instructor's workstation.

The brake system controls 140 are connected to control devices 160.

The invention works as follows.

The process of training the driver to work with the brake system of the rolling stock is implemented by a number of main stages, which are represented by flowcharts in Fig. 2-4, and includes:

Step 200, where the instructor selects a training scenario from the database 110 of training scenarios by interacting with the script input means 121 .

Step 300, at which the means 130 for displaying graphic data of the driver's workplace displays the traffic situation according to the training scenario

The error detection step 400 by the driver error recognition block 102 is implemented as follows:

Steps 410 and 420, in which the driver acts on the controls 140, after which they send signals to the central control device 100 to control the brake devices 150.

Step 430, at which the control devices 160 collect data on the application of the brake system controls by the driver using the sensors for applying the brake controls.

Step 440, in which the control devices 160 send the data collected in step 430 to the driver error recognition unit 102.

Step 450, in which block 102 compares the data collected by monitors 160 with an error condition table stored in block 102's memory.

The table contains groups of conditions corresponding to improper control of the brake system controls by the driver.

Mismanagement by the driver of the brake system controls means, for example, the transfer of the driver's crane from the emergency position to the holiday position before the train stops, while a different position of the crane is required.

Also, improper control by the driver of the brake system controls means, for example, the shift by the driver of the auxiliary brake valve handle to position VI instead of III, as a result of which the air pressure is set at 0.38-0.40 MPa instead of the required 0.10-0.13 MPa .

In addition, improper action by the driver on the brake system controls with a force lower than necessary means, for example, moving the driver’s crane handle to position III instead of the required position IV, due to which there is an overlap without power supply to the line, while shutdown with power is necessary. lines with compressed air.

The table also contains the types of errors that can be made by the driver. For example, the table contains such types of errors as: "Cessation of emergency braking before the train stops", "Use of the auxiliary brake valve when checking the operation of the brakes along the route" and others.

In the process of data comparison, the fulfillment of the groups of conditions of this table is checked, corresponding to the driver's incorrect control of the brake system controls, and if they are met, at step 460, block 102 fixes the error and its type.

If none of the conditions or group of conditions is met, block 102 returns to step 450 for comparing the data collected by control devices 160 with a table of error fixation conditions.

Step 500, at which the driver error recognition unit 102 stops recording and saves the data obtained during the interaction of the driver with the brake system controls, is implemented as follows:

Step 510, in which block 101 generates a graph of the processes occurring in the brake system, based on data obtained during the interaction of the driver with the controls of the brake system.

Step 520, at which block 102 stops the formation of a schedule of processes occurring in the brake system.

Step 530, at which block 101 sends the generated schedule of processes occurring in the brake system to means 130.

Upon completion of the step of stopping the recording and saving data at step 600, the tool 130 displays the type of error made by the driver and a graph of the processes occurring in the brake system before the driver made the error, which allows them to be studied in detail and used to make further decisions in the process of learning to control the brake system traction rolling stock.

This ensures the achievement of the technical result, which consists in ensuring the possibility of detecting by the central control device errors made by the driver in the process of interacting with the brake system controls of the procedural simulator for teaching the driver to work with the brake system of the rolling stock, thereby expanding the functionality of the procedural simulator for teaching the driver to work with rolling stock braking system.
