In this process, the thickness of the lines or the size of components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user or operator's intention or practice. Therefore, the definition of these terms should be made based on the contents throughout the specification.

1 is a block diagram showing the configuration of a variable simulator for a railway vehicle according to an embodiment of the present invention.

Referring to FIG. 1, the variable simulator 100 for a railroad vehicle according to an embodiment of the present invention can freely output various devices such as an image output unit, an instrument panel, and an operation device provided on the inside of a railroad car cab as an interface on a display. It is for evaluating the driver machine interface (DMI) of the railroad cab by arranging and comparing and verifying it with a standard, and the like. The storage unit 110, the display 120, the input unit 130, and the control unit 140 are evaluated. Includes.

Libraries corresponding to various devices installed in the railroad cab are stored in the storage unit 110. Specifically, pre-registered libraries are stored in the storage unit 110, and libraries of new cab devices not stored in the storage unit 110 may be additionally manufactured and registered by a user. In this case, the libraries of the cab devices newly registered in the storage unit 110 are matched with the driving functions of similar registered cab devices so that they can be operated during operation on the simulator.

On the other hand, in the storage unit 110, in addition to the library, data on standard specifications of the cab device and a DMI checklist of the railroad cab are stored. The data on the standard specifications of the cab device serves as a criterion for comparing and verifying the suitability of the interface displayed on the display, and the DMI checklist of the railroad cab finally evaluates the stability and user convenience of the cab DMI after completing the deployment of the interface. Is used.

The display 120 is for displaying a library that is called through an operation of the user's input unit 130 as an interface, and a plurality of displays are provided to face each user.

In this case, at least one of the plurality of displays 120 is configured to be movable in a tilting and three-axis (x-axis, y-axis, z-axis) direction, and at least one of the plurality of displays to display different interfaces It can be divided into regions.

That is, the user can move the tilting and three-axis directions of each of the plurality of displays 120 to simulate the actual driving environment through the display 120.

Meanwhile, in the above-described embodiment, the display 120 itself is tilted and the movement in the 3-axis direction is described as an example, but the technical scope of the present invention is not limited thereto. In particular, while maintaining the arrangement of the display 120 in a current state, the position, angle, shape, and size of the interface may be adjusted according to a user's touch method. This will be described later.

That is, when evaluating the cab DMI, the user tests the railway vehicle variable simulator 100 to verify user convenience and system stability. 120) as described above.

For example, the cab devices arranged adjacent to each other in the actual cab output areas by dividing the area on one display 120, and the cab devices arranged at a long distance are output on another display to move the display itself or adjust the angle. Therefore, according to the present invention, since the simulation can be performed in the same environment as the actual environment, it is possible to more accurately evaluate the cab DMI.

On the other hand, the tilting of the display 120 may be performed by a method in which the display 120 is hinged to the support, and the three-axis movement of the display 120 can be implemented by applying a link coupling structure known to the support, so detailed here. Explanation is omitted.

The input unit 130 receives user control commands for controlling the library and the interface. That is, the input unit 130 is operated by a user for selection, call, storage of a library, as well as movement and arrangement of an interface, and may use a known input device such as a keyboard, mouse, stick-type controller, touch screen, and the like. And is not particularly limited.

The control unit 140 calls the library selected by the user through the input unit 130 and outputs it to the display 120 as an interface.

In this case, the interface displayed on the display 120 may be disposed at a location desired by the user using a user input value or a stick-type controller. The input value for the layout of the interface may be x, y coordinate values for the size and position of the interface, the rotation angle of the interface (deg), etc. Also, when using a stick-type controller, the user directly controls the stick to specify the interface. It can be moved and placed in a position. Meanwhile, the interface arranged in this manner may be registered or deleted as necessary.

On the other hand, the control unit 140 may move the display 120 in a tilting and three-axis direction, but may additionally adjust or rotate the angle of the interface according to the user's touch method input through the touch screen, and additionally the interface The size of can also be adjusted.

For example, the control unit 140 may change at least one of the position, angle, and shape of the interface through a drag method, a multi-touch method, or a drag and touch mixture method as a touch method for the interface.

2 illustrates an example in which a user touches an interface and then drags to move the position of the interface. When the interface is dragged through the touch screen, the controller 140 moves the position of the interface to the dragged position. That is, as illustrated in FIG. 2, when a user touches an interface to be moved and drags it to a target position, the controller 140 moves the position of the interface according to the user's drag.

3 shows an example of adjusting the angle of the interface through a multi-touch method. When both sides of the interface are dragged at the same time through the touch screen, the controller 140 changes the angle or shape of the interface according to the dragging direction. That is, as illustrated in FIG. 3, when a user double-touches an interface to be rotated and rotates in a direction to rotate, the controller 140 rotates the interface according to the double touch and rotation of the user. .

4 shows an example of changing the shape of the interface by simultaneously performing drag and touch. When one side of the interface is touched through the touch screen and the other side is dragged, the controller 140 changes the shape of the interface according to the dragging direction. In this case, the shape of the interface is changed based on the touched point.

That is, as illustrated in FIG. 4, when the lower portion of the interface is touched and dragged upward, the upper portion of the interface is narrowed, so that a perspective is felt on the interface.

5 shows an example of changing the shape of the interface by performing dragging in opposite directions. When both sides of the interface are dragged at the same time through the touch screen, the controller 140 changes the angle or shape of the interface according to the dragging direction. That is, as illustrated in FIG. 5A, when the user simultaneously touches both sides of the interface and simultaneously drags toward the center of the interface, the controller 140 reduces the width of the interface. On the other hand, when a user simultaneously drags both sides of the interface unit in the width direction of the interface unit, the controller 140 increases the width of the interface. In addition, as illustrated in FIG. 5B, when the user simultaneously drags toward the center of the interface while touching the upper and lower portions of the interface, the controller 140 reduces the height of the interface. On the other hand, if the user simultaneously drags the upper and lower portions of the interface in the height direction of the interface, the controller 140 increases the height of the interface.

That is, the control unit 140 changes the at least one of the position, angle, and shape of the interface according to the user's touch method, without changing the display 120 in the tilting and 3-axis (x-axis, y-axis, z-axis) directions. The actual driving environment can be simulated, and the display 120 can be compensated even after tilting and changing in the 3 axis (x-axis, y-axis, z-axis) direction, thereby improving its accuracy when simulating the actual driving environment. have.

The control unit 140 compares and verifies the deployed interface with the standard specification data stored in the storage unit 110, receives the user's input value for the cab DMI checklist, and transmits it to the manager module. In this case, the input value of the user transmitted to the manager module is output to the display so that the manager can check. Therefore, the administrator can evaluate the user convenience for the interface and system stability by checking the simulation result of the user on the cab DMI checklist through the display.

As described above, according to an embodiment of the present invention, the user can freely configure the cab DMI on the simulator, and it can be evaluated by comparing and verifying its validity with a standard specification.

Hereinafter, a method for evaluating a railway vehicle cab DMI using a variable simulator for a railway vehicle according to an embodiment of the present invention will be described with reference to the drawings.

6 and 7, a method for evaluating a railway vehicle cab DMI according to an embodiment of the present invention includes a cab DMI model selection step (10), a cab layout design criteria comparison and verification step, and a cab Each step will be described in detail below, including the DMI library production step, the library call and deployment step, the standard specification comparison and verification step, and the DMI evaluation step by the engineer.

First, a cab DMI model is selected (S10). The cab DMI model is a basic interface in which various cab devices are arranged, and a plurality of vehicle models are provided and stored in a storage unit, and is called from a storage unit according to a user's input unit operation and output to a display. In this case, of course, a new cab DMI model may be separately produced and registered and stored in the storage unit.

Thereafter, for the selected cab DMI model, requirements regarding overall layout of the cab, such as UIC 651, are tested by referring to human standards, such as visibility, chair arrangement, and cab structure. The human body standard is data related to the user's height, eye height, and arm length as defined in UIC 651, and is stored in the storage unit, and is a standard for evaluating user suitability for the overall layout of the cab.

In this case, the overall layout of the cab is overlaid by outputting the design drawings and reference drawings of the selected cab DMI model on the display and then intuitively comparing and verifying (S20). Specifically, as shown in FIG. 8, the controller evaluates the overall layout of the cab by superimposing a design drawing (in red) of the cab DMI model and a reference drawing (in blue) of UIC 651 on the display. Can be. That is, if the design drawing is within the allowable range of the reference drawing, it is suitable as the layout of the cab, and if it is outside the allowable range, it may be determined that it is not suitable (S30), and in this case, the interface design is changed (S40). For reference, the point indicated on the reference drawing of FIG. 8 represents a SRP (Seat Reference Position).

Thereafter, the new cab device not registered in the library is simulated and produced based on the image (S50), and the produced new cab device is registered in the library. In this case, the cab device newly registered in the library coincides with the driving function of a similar cab device that is already registered in the storage unit, so that it can be operated during operation on the simulator.

In this regard, FIG. 9 shows an example of creating a new device and registering it in a library, and FIG. 10 shows an example of matching the device with a driving function. Referring to FIGS. 9 and 10, the main language shown in the lower portion of FIG. 9 is a device used for the operation and braking of a railroad vehicle and is integrated among the cab DMIs of UIC 612 pre-registered in the storage unit as shown in FIG. 10. Since it performs the same function as the combined traction/generation braking control device with engineer activity control push button, matching and registering the control device and driving function allows the vehicle to be operated and braked according to the user's input manipulation in the simulation process. .

When the production and registration of the library is completed, a required library is called from a newly registered library or a previously registered library and placed in the cab DMI model output on the display (S60). In this case, the arrangement of the library can be made by the user's input value or stick-type controller. Specifically, the arrangement of the library using the input value is the size of the device on the input screen, the x and y coordinates of the position, and the rotation angle ( deg), etc. In addition, the arrangement of the library using the stick-type controller moves the library through the x-axis and y-axis manipulation of the stick-type controller while the user checks the interface output on the display.

On the other hand, the completed interface is compared and verified with the standard specification as described below (S70), and as a result, if it is determined that there is an error by determining whether it is suitable (S80), it can be deleted and relocated through a design change (S90). have. For reference, FIG. 11 shows an example of arranging a cab device in a variable manner according to the above-described method.

Subsequently, verification is performed by checking whether the deployed interface conforms to a standard specification, for example, UIC 612, within a range suggested by the standard specification. In this case, whether the interface conforms to the standard specification can be verified by creating a training evaluation scenario, reproducing normal, unusual, and accident situations, and detecting device operation.

Finally, as shown in FIG. 12, the user performs a test operation of the simulator by using a cab DMI checklist stored in the storage unit and testing the user convenience by conducting a simulator test operation on the manufactured cab DMI. , FIG. 9 illustrates the state of evaluating and controlling the cab DMI and the cab DMI checklist. Specifically, the control unit outputs the cab DMI checklist as shown in FIG. 13 to the display, and when the user inputs a specific value, the input value is transmitted to the manager module by the control unit and output on the display. Therefore, the administrator checks the user's input value to the cab DMI checklist and evaluates user convenience and system stability for the interface (S100) and outputs the result (S110).

In this case, if an error occurs in any one of the above-described steps, the previous step may be re-executed through a design change (S120), and improvements may be derived and reflected through this process (S130).

For example, if there is an abnormality as a result of comparing and verifying the cab DMI model and the cab layout design criteria, or the interface and standard specifications of the cab device, do not perform the next step, change the design based on the verification result, and then go back to the previous step. You can go back and make improvements. In addition, if it is determined that there is an error as a result of the safety evaluation of the cab DMI by the user, which is the final step, improvement can be derived through design changes, and reflecting this can be performed again from the selection stage of the cab DMI model.

The embodiments of the present invention have been described above in detail with reference to the drawings. The description of the present invention is for illustrative purposes, and those having ordinary knowledge in the technical field to which the present invention pertains have changed the technical spirit or essential features of the present invention. It will be understood that other concrete forms can be easily transformed without doing so.

Therefore, the scope of the present invention is indicated by the claims, which will be described later, rather than by the detailed description above, and all modified or modified forms derived from the meaning, scope, and equivalent concepts of the claims are included in the scope of the present invention.
