More particularly, the present invention relates to a railway vehicle variable simulator for providing a railway vehicle cab with improved driver convenience and system stability, And a method for evaluating the DMI of a railroad car cab using the same.

Generally, a cabin of a railway car is a place where control is performed so that a railway car can be safely operated while transmitting and receiving various information with a control room, a ground facility, etc. To this end, a driver operates a railway vehicle, Various devices such as an instrument panel, a display, and an operation device necessary for the operation are provided.

However, if the above-mentioned various cabin devices are not disposed in the cabin or are not efficiently designed, the convenience of the driver and the stability of the system are deteriorated, which may hinder safe driving. Therefore, the DMI (Driver Machine Interface) design of the cab is very important for railway safety.

However, conventionally, when designing the cab, the cab is directly manufactured in the form of prototype, which is time-consuming and costly. In addition, there is a problem that it is difficult to evaluate the manufactured cab and reflect the evaluation result in the cab.

As a result, the cab of the railway vehicle manufactured according to the prior art is often insufficiently stable in terms of user convenience and system stability.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a railway vehicle which can improve the convenience of the user and the stability of the system by evaluating and simulating the railway car cabin, And to provide a method for evaluating a DMI of a railway vehicle cab using the variable simulator.

Another object of the present invention is to provide a variable simulator for a railway vehicle which can be applied to railway vehicles having different specifications, and a method for evaluating a DMI of a railway vehicle cab using the simulator.

As means for solving the above-mentioned technical problem,

In this case, the display may be divided into a plurality of areas such that a plurality of displays are provided, facing each other, and at least one interface is displayed.

In this case, at least another one of the displays may be configured to be movable in a tilting and triaxial direction.

In this case, a DMI (Driver Machine Interface) check list of the railway car cab may be stored in the storage unit, and the controller may output the DMI check list to the display.

In this case, the control unit may receive the input value of the user for the DMI check list through the input unit and transmit the input value to the manager module.

According to another aspect of the present invention, there is provided a method for evaluating a DMI (Driver Machine Interface) of a railway vehicle cab using a variable-type simulator for a railway vehicle, the method comprising the steps of: (a) (b) comparing and verifying the selected cab DMI model with cab layout design criteria; (c) receiving information about a new device to be placed in the cab from a user and registering the new device in the library; (d) calling the library selected by the user from the library registered in step (c) and the pre-registered library according to the input of the user, placing the library in the cab DMI model, and outputting the library to the display; (e) comparing and verifying the interface with a standard specification; And (f) evaluating the verified cab DMI based on the input value of the user, to provide a method for evaluating the DMI of a railroad car cab using a variable simulator for a railway vehicle.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

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

Referring to FIG. 1, a variable-type simulator 100 for a railway vehicle according to a preferred embodiment of the present invention outputs various devices such as a video output unit, a dashboard, an operation device, A display 120, an input unit 130, and a control unit 140, for evaluating a DMI (Driver Machine Interface) of a railway vehicle cab by comparing and verifying the DMI .

In the storage unit 110, libraries corresponding to various devices installed in a railroad car cabin are stored. Specifically, the pre-registered libraries are stored in the storage unit 110, and the libraries of the new cab equipment not stored in the storage unit 110 can be additionally manufactured and registered by the user. In this case, the library of the cab equipment newly registered in the storage unit 110 coincides with the operation function of the similar cab equipment previously registered, so that the operation can be performed in the driving operation on the simulator.

In addition to the library, the storage unit 110 stores data on standard specifications of the cab equipment and a DMI check list of the cab of the railroad car. The data on the standard specifications of the cab equipment are used as a basis for comparing and verifying the suitability of the interface displayed on the display and the DMI check list of the rail car operator cab is used to evaluate the stability and user convenience of the cab DMI .

The display 120 is provided to display a library called through an operation of the user's input unit 130 as an interface, and is arranged to face each user.

In this case, at least one of the plurality of displays 120 is configured to be movable in the tilting and 3-axis (x-axis, y-axis, z-axis) direction, Area. ≪ / RTI >

That is, at the time of evaluating the cabin DMI, the user commissiones the variable-type simulator 100 for a railway car to verify the user's convenience and the system stability. In order to realize such a trial driving environment, As shown in FIG.

For example, the cabin apparatuses disposed adjacent to each other in the actual cabin are divided into a single display area 120, and the cabin apparatuses arranged at a long distance are output to other displays, It simulates the operating environment. Therefore, according to the present invention, it is possible to evaluate the cab DMI more accurately because the simulation can be performed in the same environment as the actual.

The tilting of the display 120 may be performed by hinging the display 120 to the support, and the movement of the display 120 in the three-axis direction may be realized by applying a link coupling structure known to the support, The explanation is omitted.

The input unit 130 is operated by a user to select, call, store, interface, move, and arrange the library, and can use a known input device such as a keyboard, a mouse, a stick type controller, a touch screen, It does not.

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

In this case, the interface displayed on the display 120 may be arranged at a position desired by the user using an input value of a user or a stick type controller. The input values for the placement of the interface can be x, y coordinate values for the size and position of the interface, the angle of rotation of the interface (deg), and so on. In addition, when the stick type controller is used, the user can directly manipulate the stick to move and position the interface to a specific position. On the other hand, the interfaces arranged in this way can be registered or deleted as needed.

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

As described above, according to the present invention, the user can freely configure the cabin DMI on the simulator, and the validity of the cab DMI can be compared with the standard specifications and verified and evaluated.

Hereinafter, a method for evaluating a railway vehicle cabin DMI using a variable-type simulator for a railway vehicle according to the present invention will be described with reference to the drawings.

FIG. 2 is a flowchart of a method for evaluating a railway vehicle cabin DMI according to a preferred embodiment of the present invention, and FIG. 3 is a diagram showing a virtuous cycle structure of a scenario and an algorithm of a method for evaluating the railway vehicle cabin DMI shown in FIG. 2 .

Referring to FIGS. 2 and 3, a method of evaluating a railway vehicle operator's room DMI according to a preferred embodiment of the present invention includes the steps of selecting a cabin DMI model, comparing and verifying cabin layout design criteria, Step, a library call and placement step, a comparison with a standard specification, a verification step, and a DMI evaluation step by an engineer.

First, select the cab DMI model. The cab DMI model is a basic interface on which various cabin devices are to be placed, many of which are stored for each type of vehicle and stored in the storage unit, and are called from the storage unit according to the operation of the user's input unit and output to the display. In this case, it is needless to say that a new cab DMI model can be separately prepared and stored in the storage unit.

Thereafter, requirements for the overall layout of the cab, such as UIC 651, for example, visibility, chair arrangement, cab structure, etc., are tested for the selected cab DMI model with reference to human standards. The human body standard is stored in the storage unit as data on the body dimensions such as the user's key, eye level, arm length, etc. prescribed in UIC 651, and is a criterion for evaluating the suitability of 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. Specifically, the control unit evaluates the overall layout of the cab by superimposing a design drawing (indicated by red) of the cab DMI model and a reference drawing (indicated by blue) such as UIC 651 on the display as shown in FIG. . That is, if the design drawing is within the permissible range of the reference drawing, it can be judged that it is suitable for the layout of the cabin, and if the design drawing is out of the allowable range, For reference, the points shown in the reference drawing of Fig. 4 represent SRP (Seat Reference Position).

Thereafter, new cab devices not registered in the library are simulated and manufactured based on images, and new cab devices manufactured are registered in the library. In this case, the cab equipment newly registered in the library is made compatible with the operation function of the similar cab equipment previously registered in the storage unit, so that the operation can be performed on the simulator.

In this regard, FIG. 5 shows an example of creating a new device and registering it in a library, and FIG. 6 shows an example of matching the device with a driving function. Referring to FIG. 5 and FIG. 6, the main theme shown in the lower part of FIG. 5 is a device used for driving and braking a railway vehicle. As shown in FIG. 6, Since it performs the same function as the combined traction / power generation braking control device with the engine activity control pushbutton, if the control device and the operation function are registered in the same manner, the railway vehicle can be operated and braked according to the user's input operation in the simulation process.

When library creation and registration are completed, the required library is called from newly registered library and pre-registered library and placed in the cab DMI model displayed on the display. In this case, the arrangement of the library can be made by the input value of the user or the stick type controller. Specifically, the arrangement of the library using the input values can be performed by inputting the size of the device, the x and y coordinates of the position, and the rotation angle (deg) on the input screen. In addition, the arrangement of the library using the stick type controller moves the library through the operation of the x-axis and y-axis of the stick type controller while confirming the interface outputted by the user on the display.

On the other hand, if the layout is judged to be in error as a result of comparison with the standard standard as described later, the layout can be rearranged through deletion and design change. For reference, FIG. 7 shows an example in which the cab equipment is arranged in a variable manner according to the above-described method.

Subsequently, verification is performed by confirming whether or not the disposed interface conforms to a standard standard, for example, UIC 612 within the category indicated by the standard specification. In this case, whether or not the interface conforms to the standard specification can be verified by creating a training evaluation scenario to reproduce normal, unusual, accident situations, and detecting the operation of the apparatus.

Finally, as shown in FIG. 8, a simulator trial operation is performed with respect to the cab DMI manufactured by the user, and the safety of the cab DMI is evaluated using the cab DMI check list stored in the storage unit to test user convenience. In this regard, FIG. 9 illustrates the manner in which the cab DMI is evaluated and controlled and the cab DMI checklist. Specifically, the control unit outputs the cab DMI check list as shown in FIG. 9 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 outputted on the display. Therefore, the administrator checks the input value of the user in the cab DMI checklist to evaluate the user convenience and system stability of the interface.

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

For example, if there is an abnormality as a result of comparing and verifying the cabin DMI model with the cab layout design standard or the cab interface and the standard specification, the design is changed based on the verification result without performing the next step, You can go back and make improvements. In addition, if it is confirmed that there is an error in the result of the DMI safety evaluation by the user at the final stage, the improvement can be derived through the design change and can be performed again from the selection stage of the cab DMI model.

The preferred embodiments of the present invention have been described in detail with reference to the drawings. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.

Therefore, the scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning, range, and equivalence of the claims are included in the scope of the present invention. .
