Description

[0001] The present invention relates to a method for controlling an HMI program via a mobile device,

The present invention relates to a method of controlling an HMI program through a mobile device, and more particularly, to a method of controlling an HMI program through a mobile device by performing biometric authentication of a user according to a requested service type, To a HMI program control method using a mobile device.

The HMI program is a program for intuitively grasping and managing the power data generated by the power system. A power system is a system that provides a function to monitor or control a power system in which power is generated and utilized.

For example, a power system may be a Supervisory Control And Data Acquisition (SCADA) system that processes and monitors large amounts of data and provides various related functions. Also, the power system may be a distributed control system (DCS) that controls a large-scale process such as a power plant, and is a system designed for automatic control of a process.

In addition, the power system may include a power management system (PMS), an energy management system (EMS), or an outage management system that uses power applications for power system management and interpretation of data obtained from the power system Or an Outage Management System (OMS).

Such a power system generates various power data for monitoring or controlling the power system such as frequency, voltage, power, charge amount, and discharge amount generated in the power system. The user uses the HMI program to intuitively identify and manage the power data generated in the power system.

HMI programs typically provide analysis capabilities using power and data from the process, either wirelessly or wired, to the software and database of the power system. To do this, the HMI program displays the power data related to the process through the monitoring screen in the form of objects that can be recognized by humans, and the user analyzes and manages the processes through the objects.

In general, the HMI program installed in a PC can be installed in a mobile device and provide a data inquiry function and a control function to the user due to the generalization of the use of the mobile device.

However, when a data inquiry and control function is provided through a mobile device, it is necessary to prevent an unauthorized user from accessing the mobile device due to the movability of the mobile device. Accordingly, a method for performing user authentication in HMI program control through a mobile device has been proposed.

Figure 1 is a flow chart illustrating a conventional method for connecting to an HMI program using a mobile device. Hereinafter, a method of performing user authentication in HMI program control through a conventional mobile device will be described in detail with reference to FIG.

Referring to FIG. 1, an HMI program installed in a conventional mobile device receives login information from a user (S10). The login information used for accessing the conventional HMI program is composed of a user ID and a password (password), each of which is a string.

The HMI program sends the received login information to the authentication server (S11). Here, the authentication server is a server of the power system or a separate server for performing the user authentication function. The authentication server transmits the user authentication result to the HMI program, and the HMI program determines whether the user is a normal user (authorized user) (S12).

If it is determined that the user is not a normal user, the HMI program receives the login information again from the user (S10). On the other hand, if it is determined that the user is a normal user, the HMI program allows the user to access (S13).

If the user requests arbitrary service to the HMI program after connecting to the HMI program, the HMI program does not perform additional user authentication because the user has already been judged to be a normal user. However, when the user requests a specific service requiring security to the HMI program, the above-described user authentication (S10 to S12) can be repeatedly performed.

However, according to the conventional user authentication method, unauthorized users can control the HMI program through the mobile device after the user authentication is performed by the normal user due to the mobility of the mobile device. Due to such security vulnerability, there is a problem that a malfunction of a power system due to a false control of an unauthorized user may occur.

In addition, according to the conventional user authentication method, when the user authentication is repeatedly performed, the user is inconvenienced to repeatedly input login information, and the continuity of the business is deteriorated accordingly.

The present invention relates to a mobile communication device capable of improving the security of HMI program control by performing user authentication through biometrics using a camera of a mobile device and displaying response data for a requested service according to a result of user authentication And an HMI program control method.

Further, the present invention provides a method of controlling an HMI program through a mobile device that can prevent a malfunction of a power system due to an unauthorized user by performing a user authentication by executing a biometric module when the requested service is a control service .

It is another object of the present invention to provide a HMI program control method through a mobile device that can enhance the promptness and security of data inquiry by performing user authentication according to the security level of the inquiry target data when the requested service is a inquiry service .

In addition, the present invention provides a HMI through a mobile device that can improve the real-time performance of data retrieval and improve the continuity of work requiring user authentication by performing user authentication at a preset cycle according to whether or not the inquiry target data is a continuous monitoring target And to provide a program control method.

The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention which are not mentioned can be understood by the following description and more clearly understood by the embodiments of the present invention. It will also be readily apparent that the objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

According to an aspect of the present invention, there is provided a method for controlling an HMI program executed in a mobile device, the method comprising the steps of: Executing a biometric module using a camera mounted on the mobile device according to the type of the service, performing user authentication using the biometric module executed, And displaying response data for the service through the mobile device.

According to the present invention as described above, the security of the HMI program control can be improved by performing the user authentication through biometrics using the camera of the mobile device and displaying the response data for the requested service according to the result of the user authentication There is an effect.

According to the present invention, when the requested service is the control service, the biometrics module is executed to perform the user authentication, thereby preventing malfunction of the power system due to the control of the unauthorized user.

In addition, according to the present invention, if the requested service is a query service, user authentication is performed according to the security level of the inquiry target data, thereby enhancing promptness and security of data inquiry.

In addition, according to the present invention, the user authentication is performed at a preset cycle according to whether the inquiry target data is a continuous monitoring target, thereby improving the real time of data inquiry and improving the durability of tasks requiring user authentication.

The above and other objects, features, and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings, which are not intended to limit the scope of the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to denote the same or similar elements.

A method for controlling an HMI program via a mobile device according to an embodiment of the present invention relates to a method for controlling an HMI program executed in a mobile device. Accordingly, the present invention can be performed by an electronic control device such as an internal CPU or an MCU of a mobile device provided with an HMI program, and such an electronic control device can be expressed by a control unit as described later.

In the present invention, the HMI program can be a program for intuitively grasping and managing the power data generated in the power system. A power system is a system that provides a function to monitor or control the power system in which power is generated and utilized.

For example, a power system may be a Supervisory Control And Data Acquisition (SCADA) system that processes and monitors large amounts of data and provides various related functions. Also, the power system may be a distributed control system (DCS) that controls a large-scale process such as a power plant, and is a system designed for automatic control of a process.

In addition, the power system may include a power management system (PMS), an energy management system (EMS), or an outage management system that uses power applications for power system management and interpretation of data obtained from the power system Or an Outage Management System (OMS).

Such a power system can generate various power data for monitoring or controlling the power system such as frequency, voltage, power, charge amount, and discharge amount generated in the power system. The user can use the HMI program to intuitively identify and manage the power data generated in the power system.

HMI programs typically provide analysis capabilities using power and data from the process, either wirelessly or wired, to the software and database of the power system. To do this, the HMI program displays the power data related to the process through the monitoring screen in the form of a human-recognizable object, and the user can analyze and manage the process through the object.

The HMI program used in the conventional PC is installed in the mobile device due to the generalization of the use of the mobile device, and can provide the data inquiry function and the control function to the user. Meanwhile, in the present invention, the mobile device may include an electronic terminal that can be used on the move, such as a smart phone or a tablet PC.

FIG. 2 is a schematic view illustrating an internal configuration of a mobile device according to an embodiment of the present invention. The HMI program control method through the mobile device of the present invention can be performed by the control unit 100 shown in FIG. As described above, the control unit 100 may include an electronic control device such as a CPU or an MCU in a mobile device.

3 is a flowchart illustrating a method of controlling an HMI program via a mobile device according to an embodiment of the present invention. Hereinafter, a process of controlling the HMI program installed in the mobile device by the control unit 100 of the present invention will be briefly described with reference to FIG. 2 and FIG.

Referring to FIG. 3, the controller 100 of the present invention can receive a service request from a user through an HMI program (S310). Here, the service may include various functions that the HMI program provides to the user. For example, the service may include a power data lookup function using an HMI program or a power system control function using an HMI program.

The control unit 100 may determine whether user authentication is required for the service requested by the user (S320). In general, user authentication may be required for security of the HMI program, which will be described in detail later.

If it is determined that user authentication for the requested service is not required as a result of the determination, the controller 100 may control the display unit 120 to display the response data for the requested service through the mobile device (S360). The display unit 120 may include any display device capable of visually displaying data, and the display unit 120 of the present invention may be included in a mobile device.

On the other hand, if it is determined that user authentication for the requested service is required as a result of the determination by the controller 100, the controller 100 may execute the biometric module 140 (S330). The control unit 100 may determine whether the user authentication is successful based on the result of performing the user authentication through the biometric module 140 (S340).

If the user authentication is successful, the control unit 100 may control the display unit 120 to display the response data for the requested service through the mobile device (S360). On the other hand, if the user authentication fails, the control unit 100 deactivates the HMI program (S350), and another service can be requested again from the user (S310).

Referring again to FIG. 2 and FIG. 3, a method of controlling the HMI program through the mobile device of the present invention will be described in detail.

In step S310 of FIG. 3, the controller 100 of the present invention can confirm the type of the requested service through the HMI program. More specifically, the HMI program can provide a service selection screen so that a user can request a service, and the control unit 100 can control the display unit 120 to display a service selection screen to a user.

As mentioned above, the display unit 120 may include any display device capable of visually displaying data, and may be, for example, a display panel of a mobile device.

The user can request a service to be provided through the service selection screen. More specifically, a user can request a corresponding service by selecting a service through an arbitrary input device such as a mouse, a keyboard, or a touch pad of the mobile device, which is interlocked with the mobile device. Accordingly, the input unit 110 of the present invention can receive a service requested by the user through the input device.

In step S320 and step S330 of FIG. 3, the controller 100 of the present invention can confirm the type of the service input by the input unit 110. FIG. More specifically, the control unit 100 can confirm what service the user has requested.

In the present invention, the HMI program can provide a look-up service for providing the user with the power data requested by the user and a control service for controlling the power system according to the user's command. Accordingly, the control unit 100 can determine whether the type of the service requested by the user is an inquiry service or a control service.

The controller 100 of the present invention can execute the biometric module 140 using the camera 130 mounted on the mobile device according to the type of the service. The biometric module 140 may be operated by a program installed in the mobile device or by a process supported by the HMI program.

The biometric module 140 may be executed only when the service requested by the user requires user authentication. More specifically, the inquiry service may require user authentication depending on the type of inquiry target data the user wants to inquire. On the other hand, since the control service changes the state of the power system, the need for user authentication may be required because security is relatively necessary.

Accordingly, the control unit 100 of the present invention can determine the type of the service requested by the user and determine whether user authentication is required for the service. In other words, if the type of the service requested by the user is the control service, the controller 100 determines that user authentication for the service is necessary and can execute the biometric module 140. [

On the other hand, if the type of the service requested by the user is the inquiry service, the control unit 100 can determine whether user authentication is required for the service according to the security level of the inquiry data, which will be described later.

In step S340 of FIG. 3, the controller 100 of the present invention can perform user authentication using the executed biometric module 140. FIG. The biometric module 140 can acquire user biometric information using the camera 130 mounted on the mobile device. The user biometric information may include at least one of face information, iris information, and vein information of the user.

For example, the facial information may include data rendered in three dimensions of the shape of the user's face or thermal distribution data of the user's face. The iris information may include data on the iris pattern of the user ' s eye. The vein information may also include data regarding the shape of the blood vessels of the hand or wrist.

The user information may be stored in advance in the mobile device or the HMI program. More specifically, the biometric information of the user who can receive the reference service for the control service or the data having the high security level as described later can be stored in advance as the user information.

The user information stored in advance may be information corresponding to the biometric information recognizable by the biometric module 140. [ More specifically, the user information may include at least one of face information of the user, iris information of the user, and vein information of the user.

The control unit 100 of the present invention can perform user authentication by comparing previously stored user information with user biometric information photographed through the camera 130. [ More specifically, when the user biometric information acquired by the biometric module 140 matches one of the user information stored in advance, the control unit 100 determines that the user requesting the service is an authenticated user, have.

On the other hand, if the user biometric information acquired by the biometric module 140 does not match any of the pre-stored user information, the control unit 100 determines that the user requesting the service is an unauthenticated user, can do.

The control unit 100 of the present invention determines that the user who requested the service is not authenticated if any one of the plurality of pieces of user biometric information does not match the user information stored in advance .

More specifically, when there are two or more users photographed through the camera 130, the user biometric information acquired by the biometric module 140 may be plural. At this time, if each of the plurality of pieces of biometric information coincides with pre-stored user information, the control unit 100 can determine that the user requesting the service is an authenticated user.

On the other hand, if any one of the plurality of pieces of biometric information does not match pre-stored user information, the user requesting the service can be determined as an unauthenticated user. In other words, the user can be successfully authenticated only when all the users photographed through the camera 130 are authenticated users.

Alternatively, the control unit 100 of the present invention may determine that a user requesting a service is an unauthenticated user, if the user biometric information is captured in accordance with the setting of the user. In other words, if more than one user is photographed to enhance the security of using the HMI program, user authentication by the biometric module 140 may fail regardless of whether each user is an authenticated user.

The controller 100 of the present invention can perform user authentication using the user biometric information photographed by the camera 130 at a predetermined cycle. More specifically, the control unit 100 may execute the biometric module 140 at a predetermined cycle to take the user biometric information at a preset cycle, and may perform user authentication at a preset cycle using the photographed user biometric information .

For example, when the user continuously requests the control service through the HMI program, the control unit 100 can perform continuous user authentication at a predetermined period of time instead of performing only one user authentication.

The predetermined period may be determined according to the user's setting, but it is preferably set to a very short period or real time in order to enhance the security of the HMI program use.

If the user authentication is performed in real time, the user can be continuously photographed by the camera 130 of the mobile device, and if the user is not photographed by the camera 130, the user authentication may fail.

In step S350 and step S360 of FIG. 3, the controller 100 of the present invention may control the display unit 120 to display response data for the requested service on the mobile device according to the user authentication result .

The response data is data corresponding to the requested service. If the requested service is the inquiry service, the response data may be the inquiry target data. If the requested service is the control service, the response data may be the control result data.

For example, if an authenticated user requests a control service, the HMI program can control the power system in response to a user command. At this time, the control unit 100 may control the display unit 120 to display the control result of the power system by the HMI program to the user.

On the other hand, if an unauthenticated user requests a service requiring user authentication, the control unit 100 may determine that an abnormal access has occurred to the HMI program. At this time, the control unit 100 deactivates the HMI program and can request another service from the user again. When the HMI program is disabled, data inquiry function and power system control function using HMI program may not be provided.

As described above, according to the present invention, if the requested service is a control service, the biometric module is executed to perform user authentication, thereby preventing a malfunction of the power system due to the control of the unauthorized user. In other words, the present invention can prevent erroneous control of the power system by essentially performing user authentication when the user wishes to control the power system.

4 is a flowchart illustrating a method of performing user authentication according to a type of a service requested by a user to display response data. Hereinafter, a method of controlling the HMI program when the requested service is the inquiry service will be described in detail with reference to FIG. 2 and FIG.

Referring to FIG. 4, the controller 100 receives a service request from the user through the HMI program (S310) and confirms the type of the requested service (S321).

If the type of the service is the inquiry service, the control unit 100 of the present invention can confirm the security level of the inquiry data (S410). Here, the data to be inquired may be the data that the user wants to inquire through the HMI program, as mentioned above.

A security level can be set for each inquiry data. Such a security level can be set differently depending on which data the user gives importance to. For example, the security level of the inquiry data having relatively high importance in the power system operation may be set to a user authentication level requiring user authentication. On the other hand, the security level of the data of relatively low importance can be set to a general level that does not require user authentication.

The control unit 100 may control the display unit 120 to display the response data through the mobile device if the security level of the inquiry target data is the general level (S360). Here, the response data may be data to be inquired. Meanwhile, the controller 100 may execute the biometric module 140 if the security level of the inquiry target data is the user authentication level (S330).

The user authentication is performed based on the user biometric information acquired by the biometric module 140 in step S340 and the response data is displayed on the basis of the user authentication result in step S360 and the HMI program is disabled in step S350. 3, the detailed description is omitted.

In addition, when the type of the service is confirmed as a control service in step S321, the operation of the present invention is the same as that described above with reference to FIG. 3, and thus a detailed description thereof will be omitted.

As described above, according to the present invention, if the requested service is a inquiry service, user authentication is performed according to the security level of the inquiry target data, so that promptness and security of data inquiry can be enhanced.

In other words, the present invention provides a data inquiry function without user authentication for the inquiry target data, which is a general rank, and enhances the security of data inquiry by performing user authentication for the inquiry target data, which is a user authentication level have.

The controller 100 of the present invention can determine whether the inquiry target data is a continuous monitoring target if the security level of the inquiry target data is a user authentication level. The persistent monitoring target may be preset according to the data to be inquired and may be set when the user requests the service.

For example, if the inquiry target data is the identification information data of the power devices constituting the power system, the inquiry target data need not be constantly monitored. On the other hand, if the inquiry target data is the power amount data generated in the power system, the inquiry target data needs to be constantly monitored.

Accordingly, the user can not set the identification information data of the power device as the continuous monitoring target, and can set the power amount data as the continuous monitoring target.

The control unit 100 may execute the biometric module 140 at a predetermined cycle according to a result of determining whether the object of inquiry data is a continuous monitoring target. More specifically, if the object of inquiry data is not the object of continuous monitoring, the control unit 100 can execute the biometric module 140 once. On the other hand, if the object of inquiry data is the object of continuous monitoring, the control unit 100 may continuously execute the biometric module 140 at a preset cycle.

Since the control unit 100 performs the user authentication using the acquired user biometric information at a predetermined period by the biometric module 140, the detailed description is omitted here.

As described above, according to the present invention, the user authentication is performed in a predetermined cycle according to whether the inquiry target data is a continuous monitoring target, thereby improving the real time of data inquiry and improving the durability of tasks requiring user authentication.

In other words, according to the present invention, the user is continuously authenticated based on the biometric information of the user photographed through the camera, so that the user can view the data that changes with time in real time.

In addition, as long as the user biometric information is captured by the camera 130, user authentication is continuously performed without inputting separate login information, thereby ensuring continuity of work using the HMI program.

5 is a flowchart illustrating a method of displaying response data by performing user authentication according to the security level of the data to be collated and whether or not to continuously monitor the data. Hereinafter, a method of performing user authentication at a predetermined cycle according to the continuous monitoring of the inquiry target data will be described in detail with reference to FIG. 2 and FIG.

5, when the inquiry target data to be inquired by the user is a user authentication level, the controller 100 determines the security level of the inquiry data (S410), executes the biometric module 140 (S330 ) User authentication (S340). If the user authentication is successful, the control unit 100 may control the display unit 120 to display the inquiry target data (S360).

When the inquiry target data is displayed for the first time, the control unit 100 can determine whether the inquiry target data is a continuous monitoring target (S510). As a result of the determination, if the inquiry target data is the object of continuous monitoring, the control unit 100 may execute the biometric module 140 at a predetermined cycle (S520).

Accordingly, the control unit 100 can perform user authentication at a preset cycle (S340), and can continuously display the inquiry target data according to the authentication result (S360).

On the other hand, when the user authentication fails, the control unit 100 deactivates the HMI program (S350) is the same as that described above with reference to FIG. 3, and thus a detailed description thereof will be omitted.

As described above, the present invention can improve the security of HMI program control by performing user authentication through biometrics using a camera of a mobile device and displaying response data for a requested service according to a result of user authentication have.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, But the present invention is not limited thereto.
