The present invention can provide a technical effect of preventing errors due to human error by proposing a method for checking secondary information through the navigator 510 . In addition, when the navigator 510 is installed at the entrance of the electrical room 500, it has the advantage of being able to easily check the state of the entire circuit breaker from the entrance of the electrical room 500, and even when an abnormal situation occurs, the electrical room 500 It can be said that it is efficient in that it can grasp the prior state from the entrance of

On the other hand, as shown in FIG. 5 , a camera device 520 may be installed in the electrical room 500 , and the management server 110 provides image information and/or acquired image information ( For example, based on a still image, a dynamic image), the user's movement (and/or movement) may be identified or identified. This may be implemented through the camera module 610 of the management server 110, which will be described in detail later with reference to FIG.

The camera device 520 may include a multi-directional camera and/or an omni-directional camera (eg, a fisheye camera). Here, the multi-directional camera may include a plurality of cameras, a plurality of image recognition devices (eg, Internet Protocol (IP) cameras or closed circuit television (CCTV) cameras, etc.), a plurality of lenses, a plurality of camera control devices, a plurality of It may include a lighting device of the or include a module for controlling the same. The omnidirectional camera may also include a fisheye camera. The IP camera may check or check the internal condition of the electrical room 500 in which the camera device 520 is installed with a user terminal (eg, smart phone, mobile phone, etc.) even outside the electrical room 500 .

6 is a block diagram illustrating the control module 210 of the management server 110 according to an embodiment of the present invention.

Referring to FIG. 6 , the control module 210 includes a camera module 610 and an artificial intelligence module 620 .

The camera module 610 may generate predetermined information by analyzing the image and/or image information obtained through the camera device 520 . The camera module 610 is a HOG (Histogram of Oriented Gradient), Haar-like feature, Co-occurrence HOG, LBP (local binary pattern), FAST (features from accelerated segment test), such as through various algorithms for object feature extraction. , extracting an outline of an object included in an image (and/or image information) from an image (and/or image information) obtained through the camera device 520 and/or a predetermined text in the area of the extracted object (or an outline corresponding to predetermined information) may be obtained. Also, the camera module 610 may generate masking image information by masking a region corresponding to an object extracted from an image (and/or image information) obtained through the camera device 520 . At this time, the masking process is, for example, a differential imaging method, a Model of Gaussian (MOG) algorithm using Gaussian Mixture Models (GMM), a codebook algorithm, etc. Object through background modeling to separate an object and a background A method of extracting an object candidate region corresponding to .

Also, the camera module 610 may control the camera device 520 based on information on a place where the camera device 520 is installed.

For example, the camera module 610 may obtain access information for the electrical room 500 in which the camera device 520 is installed. For example, a plurality of entrances (eg, a first entrance, a second entrance, etc.) (eg, an entrance door, an emergency exit) may exist in the electrical room 500 in which the camera device 520 is installed, for example, the camera device An object extracted from the image (and/or image information) obtained through 520 may correspond to a person (or an employee), and the extracted object enters through the first doorway (or the second doorway) it can be recognized that

When the number of times that the extracted object is recognized that it has entered through the first doorway (or the second doorway) is greater than or equal to a predetermined number threshold value (or the number of times recognized “for a predetermined time”) It may be determined that the first condition is satisfied when the predetermined number of times is equal to or greater than the threshold value). For example, when the first condition is satisfied, the camera module 610 controls the camera device 520 to photograph the first doorway, or transmits information about an image captured by the first doorway to another image. A multi-directional camera module (or multi-directional camera device) that stores for a longer period of time (eg, recorded in the storage module 250), shoots the first doorway in higher quality, or captures the first doorway By controlling at least one camera device (or camera lens) provided in the , a further enlarged image (eg, a zoomed-in image) may be controlled to be photographed (or acquired). As another example, the camera module 610 transmits information indicating that the first condition is satisfied to the control module 210 (and/or the first power control device 530 , the second power control device 540 , and/or Alternatively, it may be transmitted to the third power control device 550), and is installed (equipped) in each of the first power control device 530 , the second power control device 540 , and/or the third power control device 550 . ) The locking unit 93 may be controlled to be locked, and/or a predetermined alarm may be displayed or output through the electronic tag display unit 20 .

Also, the camera module 610 may control the camera device 520 based on weather information. For example, the weather information acquired through the camera module 610 may include comprehensive information on weather (eg, daily weather information, weather forecast information, last year's weather information, etc.).

In addition, the camera module 610, based on the weather information, brightness (eg, illuminance (lx), luminance (cd), luminous flux (lm), luminance (cd/m ² or sb), luminous flux divergence (rlx) etc.) can be set (eg, reference value, optimal value, minimum value, maximum value). In addition, the camera module 610 determines the optimal illuminance of a place where the camera device 520 is installed and/or a place where the camera device 520 shoots based on brightness information (eg, change in brightness) (or calculation) and control the camera device 520 to take pictures according to the determined optimal illuminance. For example, the camera module 610 applies a weight according to the brightness information to a value for the illuminance (eg, reference illuminance), so that the location where the camera device 520 is installed and/or the camera device 520 is photographed. It is possible to determine (or calculate) the optimal illuminance of the place.

In addition, the camera module 610 is a value for the power of the camera device 520 based on the weather information (eg, a value for reserve power, power consumption, minimum charging power, maximum charging power, etc.) or a power mode (eg ; safe mode, maximum performance mode, etc.). For example, when the weather information indicates information that a thunderstorm is expected today (today), power is not supplied (or power is cut off) to the camera device 520 (or the camera module 610) due to a thunderstorm In order to prepare for , the camera module 610 may set the value for the reserve power to a value greater than or equal to a predetermined value or set the power mode to the safe mode.

Also, the camera module 610 may acquire an outline of an object in an image or a text (or an outline (or outline) indicating information) that can be extracted from the object from the image acquired through the camera device 520 . For example, text engraved on clothes worn by a person (ie, object) photographed in the acquired image may be extracted, and the camera module 610 may perform a different operation based on information indicated by the extracted text or the camera module (110) can be controlled. In addition, when the information indicated by the extracted text is information indicating that a specific occupation, for example, a circuit breaker operator, user B (eg, SBO) and/or user C (eg, electric power plant manager)), the camera module 610 ) can give specific control to the image in which the extracted text is engraved on the object (person). For example, the camera module 610 manages the image as a separate list, tracks the movement path of the object (eg, whether the object is moved and photographed in another image (or exists)) By confirming, the movement path of the object can be tracked), (when the power mode is set to the safe mode), the storage period of the image captured by the object can be set to be shorter (the object is a constant photographing object, so power is saved) may be a setting for ).

As described above, the camera module 610 is configured to extract object features such as Histogram of Oriented Gradient (HOG), Haar-like feature, Co-occurrence HOG, local binary pattern (LBP), features from accelerated segment test (FAST), etc. Through various algorithms, the outline of the object in the image or the text (or the outline (or outline) representing information) that can be extracted from the object may be obtained from the image acquired through the camera device 520 .

Also, the camera module 610 may generate a predetermined event when an object corresponding to the management target is included in the acquired image. For example, when an object designated as a management target, such as a blacklist, is identified in an image more than a predetermined number of times (or when the management target is included in an image acquired by the camera module (more than a predetermined number of times)) By determining that the condition of is satisfied, the camera module 610 may generate a predetermined event. In this regard, the camera module 610 controls, for example, an alarm device (eg, a warning light, a speaker) installed in a specific place to operate, or controls the camera device 520 to acquire an image of the management target. Alternatively, an alarm or a corresponding signal (or information) may be transmitted to the server room, management room, and/or control room. Here, controlling the camera device 520 so that the camera module 610 acquires the image of the management object may control, for example, the camera apparatus 520 to acquire a high-quality image of the management object. (For example, it is stored or managed in the camera module 610, the camera device 520, and/or the storage module 250 to be described later with higher image quality for the part where the management target is captured than the surrounding background or other objects. it can be done). In addition, controlling the camera device 520 so that the camera module 610 acquires the image of the management target is, for example, the camera device 520 (or the camera module 610 and/or the camera device) A command for instructing the camera rotation (or zoom-in, zoom-out) so that the camera (controlled by 520) continues to shoot the management object and/or an image obtained by a plurality of cameras to photograph the management object may include an operation of generating a command for instructing editing (or synthesizing) of .

In addition, while the object to be managed (or to be monitored) moves from the first position to the fourth position, it passes through the first monitoring area, the second monitoring area, the third monitoring area, and the fourth monitoring area, and each monitoring area A difference may occur between the images obtained from the first to fourth cameras (eg, C1, C2, C3, C4) installed corresponding to the , depending on the specifications or angle of the camera. For example, the resolution of the image according to the camera specifications of different cameras between the first camera to the fourth camera, the degree of zoom-in (or degree of zoom-out), and/or the shooting angle, etc.; Differences occur in color, angle, and the like. Accordingly, even if the object extracted from each image is the same object, different values may be calculated (or obtained) depending on the resolution, color, angle, etc. when extracting feature information. Accordingly, the camera module 610 and/or the camera device 520 recognizes the same object as a different object in images captured by different cameras, thereby reducing the reliability and efficiency of object tracking, and is limited to the monitoring area of each camera. Therefore, object tracking is performed, so object tracking may be disconnected.

To solve this, the camera module 610 and/or the camera device 520 may receive object characteristic information obtained through the camera device 520 from the image of the first camera C1 targeting a different monitoring area. can In this case, the camera device 520 may determine whether the object moving in the monitoring area of the first camera C1 is the same object based on the object characteristic information, and may track the same object based on this. . In this case, the camera device 520 may use an object tracking method using, for example, a Kalman filter. Here, the Kalman filter may include an optimal mathematical calculation process for predicting a position after a predetermined time by analyzing an existing observation value (eg, image or image information) mixed with noise through the least squares method.

Meanwhile, the camera module 610 and/or the camera device 520 may continuously extract a plurality of object characteristic information obtained from various postures and positions of the same object and transmit it to the camera module 610, and each object An image (or image information) corresponding to the feature information may also be transmitted to the camera module 610 together. In this case, the camera module 610 may extract the object characteristic information and image information selected according to a user input through the input module 230 from the storage module 250 in which the object characteristic information and the image information are mapped and stored. .

In addition, the camera module 610 and/or the camera device 520 acquires (or receives) object characteristic information that is continuously extracted and transmitted through the image processing unit 110 in the monitoring area of the first camera C1. )can do. In addition, the camera module 610 and/or the camera device 520 may determine whether existing object characteristic information matching the object characteristic information by a preset level or more exists in the storage module 250 . At this time, the camera module 610 compares the object characteristic information with the existing object characteristic information, and when there is no existing object characteristic information that matches a preset level or more, the camera module 610 transmits the object characteristic information to a server (eg, the camera module of FIG. 3 to be described later). (610)) may be requested. In addition, the camera module 610 and/or the camera device 520 assigns a new identifier (ID) to an object corresponding to the object characteristic information, and provides the storage module 250 with the identifier and the object characteristic information. can be mapped and saved.

The artificial intelligence module 620 may be a hardware module and/or a software module operating an artificial intelligence network, and may determine or generate a predetermined threshold based on the artificial intelligence network. Also, the artificial intelligence module 620 may determine or set the predetermined threshold by using machine learning on big data stored in the storage module 650 .

In addition, the artificial intelligence module 620 learns the artificial intelligence network using the big data stored in the storage module 250 of the management server 110 as an input variable, specifically, deep learning, which is a field of machine learning. Learning is performed so that an accurate correlation can be derived using the technique. For example, the artificial intelligence module 620 may learn the artificial intelligence network by using the image and/or image information acquired through the camera device 520 , a predetermined threshold, and the like as learning data. For example, the artificial intelligence module 620 may determine or reset the predetermined threshold using the learned artificial intelligence network.

Also, the artificial intelligence module 620 may calculate a weight of a plurality of inputs in the function through deep learning through learning. In addition, various models such as a Recurrent Neural Network (RNN), a Deep Neural Network (DNN), and a Dynamic Recurrent Neural Network (DRNN) may be used as an AI network model used for such learning.

Here, RNN is a deep learning technique that simultaneously considers current data and past data. A recurrent neural network (RNN) represents a neural network in which connections between units constituting an artificial neural network constitute a directed cycle. Furthermore, various methods may be used for a structure capable of constructing a recurrent neural network (RNN), for example, a fully recurrent network, a hopfield network, an Elman network, an ESN (Echo). State network), long short term memory network (LSTM), bi-directional RNN, continuous-time RNN (CTRNN), hierarchical RNN, and secondary RNN are representative examples. In addition, as a method for learning a recurrent neural network (RNN), methods such as gradient descent, Hessian Free Optimization, and Global Optimization Method may be used.

Embodiments of the present invention disclosed in the present specification and drawings are merely provided for specific examples in order to easily explain the technical contents of the present invention and help the understanding of the present invention, and are not intended to limit the scope of the present invention. That is, it will be apparent to those of ordinary skill in the art to which the present invention pertains that other modifications can be implemented based on the technical spirit of the present invention. In addition, each of the above embodiments may be operated in combination with each other as needed. For example, all embodiments of the present invention may be implemented by the power control device 10 , the system 100 , the management server 110 , and/or the user terminal 120 in combination with each other in parts.

In addition, the method for controlling the power control device 10, the system 100, the management server 110, and/or the user terminal 120 according to the present invention is in the form of a program command that can be executed through various computer means. It may be implemented and recorded in a computer-readable medium.

As such, various embodiments of the present invention may be embodied as computer readable code on a computer readable recording medium in a particular aspect. A computer readable recording medium is any data storage device capable of storing data that can be read by a computer system. Examples of computer readable recording media include read only memory (ROM), random access memory (RAM), and compact disk-read only memory (CD-ROM). ), magnetic tapes, floppy disks, optical data storage devices, and carrier waves (such as data transmission over the Internet). The computer readable recording medium may also be distributed over network-connected computer systems, so that the computer readable code is stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for achieving various embodiments of the present invention may be easily interpreted by programmers skilled in the field to which the present invention is applied.

Additionally, the camera module 610 is configured to focus the multi-directional camera and/or the omni-directional camera included in the camera device 520 by using a predetermined terminal (eg, a terminal 120 of a breaker operator, or an administrator terminal). You can control it to fit. Meanwhile, for convenience of description, the predetermined terminal may be referred to as a focus reference terminal hereinafter.

When the distance information representing the distance difference between the first location information indicated by the location information of the focus reference terminal and the second location information representing the information on which the camera device 520 is located is lower than a predetermined threshold value, the camera device ( 520) and/or the camera module 610 may operate or be set in a focus setting mode. In other words, when the focus reference terminal is located within a predetermined distance from the camera device 520, it can be considered that the condition for performing the focus setting mode is satisfied. The camera module 610 set to the focus setting mode may control the multi-directional camera and the omni-directional camera of the camera device 520 to sequentially operate. For example, when the focus setting mode is set, the multi-directional camera performs an operation for focusing the multi-directional camera based on the focus reference terminal between a first focus timing and a second focus timing, and The omni-directional camera may perform an operation for focusing the omni-directional camera with respect to the focus reference terminal between the third focus timing and the fourth focus timing. The first focus timing may have priority over the second focus timing, and the third focus timing may have priority over the fourth focus timing.

Meanwhile, it may be preferable that the focus reference terminal does not move between the first focus timing and the second focus timing, and between the third focus timing and the fourth focus timing. However, when the focus reference terminal moves more than a predetermined reference between the first focus timing and the second focus timing, and between the third focus timing and the fourth focus timing, it is the user ( or the administrator) may consider that the intention of refocusing the cameras in the device is to restart the focusing operation of the cameras in the device. For example, the first location information of the focus reference terminal may be obtained based on Global Navigation Satellite System (GNSS) information and/or at least one short-range communication signal (eg, a beacon signal), and the focus The height information indicating the height of the reference terminal may be obtained (and/or set) based on air pressure measured by a barometer provided in the focus reference terminal. As an example, when the first change amount of the first location information is higher than the fixed position threshold value and the second change amount of the height information is higher than the fixed height threshold value, the focusing operation of the cameras in the device may be restarted. (or the focusing process can be re-run). As another example, when i) the first amount of change with respect to the first location information is higher than a fixed position threshold and the second amount of change with respect to the height information is lower than the fixed height threshold, ii) the first change with respect to the first location information When the change amount is lower than the position fixation threshold and the second change amount for the height information is higher than the height fixation threshold, the manager (or user) of the focus reference terminal does not intend to refocus, but moves by mistake Therefore, it can be seen that the position/height of the focus reference terminal has changed, so that the camera device 520 and/or the camera module 610 may cause the camera device 520 to output an alarm signal. Through this, the user (or the manager) of the focus reference terminal may recognize that he/she moves and interferes with focusing the camera.

In addition, it will be appreciated that the apparatus and method according to various embodiments of the present invention can be realized in the form of hardware, software, or a combination of hardware and software. Such software may contain, for example, a volatile or non-volatile storage device such as a ROM, or a memory such as, for example, RAM, a memory chip, device or integrated circuit, whether erasable or rewritable, or For example, the storage medium may be stored in an optically or magnetically recordable storage medium such as a compact disk (CD), DVD, magnetic disk or magnetic tape, and at the same time, a machine (eg, computer) readable storage medium.
