Referring to Figures 1 to 3, the underground cable monitoring system according to an embodiment of the present invention may include a camera 100, a vibration detection sensor 200, a speaker 300, and a server 400.

The camera 100 can capture images of a section where an underground cable is installed. According to one embodiment, the camera 100 may be a CCTV, capture images of a section where an underground cable is installed, and transmit the captured images to the server 400, which will be described later. The camera 100 may include a modem for wired or wireless communication with the server 400, and a GPS for measuring location information. Referring to FIG. 2, the camera 100 may be installed in a location where a support suitable for attaching the camera 100 or a utility pole exists near a section where an underground cable is installed.

The vibration detection sensor 200 can detect a vibration signal occurring in a section where an underground cable is installed. The vibration detection sensor 200 can detect surrounding vibration signals and transmit the detected vibration signals to the server 400. The vibration detection sensor may include a modem for wired or wireless communication with the server 400, and GPS for measuring location information. Referring to FIG. 2, the vibration detection sensor 200 may be installed inside a pipeline through which an underground cable is installed or a manhole through which an underground cable is installed. The vibration detection sensor 200 may be installed in a location where there is no suitable support for attaching the utility pole or camera 100 near the section where the underground cable is installed, or where it is difficult to install the camera 100.

The speaker 300 is provided in the section where the underground cable is installed and can output a warning under the control of the server 400. The speaker 300 can output various warning sounds according to the control of the server 400.

The server 400 receives an image captured through the camera 100 or a vibration signal detected through the vibration detection sensor 200, and performs excavation work within the section where the underground cable is installed based on the received image or vibration signal. Determine whether to implement, and if it is determined that excavation work is being carried out in the section, determine whether the excavation work is unauthorized excavation work, and if it is determined that the excavation work is unauthorized excavation work, a warning is issued through the speaker 300. can be output.

Below, we will look at the operation process of the server 400 in detail.

First, the server 400 can receive images captured through the camera 100. According to one embodiment, the image captured through the camera 100 may be transmitted to the server 400 only when a predetermined change (i.e., movement) occurs in the image captured through the camera 100. That is, the camera 100 can transmit the captured image to the server 400 only when a predetermined change occurs in the captured image. According to another embodiment, images captured through the camera 100 may be transmitted to the server 400 in real time.

Additionally, the server 400 may receive a vibration signal detected through the vibration detection sensor 200. According to one embodiment, the vibration signal may be transmitted to the server 400 only when the intensity is equal to or higher than a preset reference intensity. That is, the vibration detection sensor 200 can transmit the detected vibration signal to the server 400 only when a vibration signal exceeding a preset reference intensity is detected. According to another embodiment, the vibration signal detected through the vibration detection sensor 200 may be transmitted to the server 400 in real time.

Subsequently, the server 400 may determine whether to perform excavation work in the section where the underground cable is installed based on the received image or vibration signal.

When determining whether to carry out excavation work in a section where an underground cable is installed based on the received video, the server 400 determines that excavation work is being performed within the section if operating excavation equipment is detected in the received video. You can judge. In other words, the server 400 can determine whether excavation work is being performed within the section by determining whether excavation equipment is operating within the section based on the received image. The server 400 can determine whether the excavation equipment is moving by analyzing the received image, and if the excavation equipment is moving, it can be determined that the excavation equipment is operating.

According to one embodiment, the server 400 determines whether there is excavation equipment (e.g., excavator, driller, excavator, etc.) in the section where the underground cable is installed based on the received image, and determines whether the excavation equipment is present in the section. If it is determined that it exists, it can be determined whether or not to carry out excavation work in the section based on the received video. At this time, the server 400 learns the image of the excavating equipment using deep learning technology, and when an image corresponding to the learned image is detected in the received video, it can be determined that the excavating equipment exists in the corresponding section. For example, the server 400 can detect excavation equipment in an image using deep learning technology such as FAST R-CNN.

If it is determined that excavation equipment exists in a section where an underground cable is installed, the server 400 may output a first warning through the speaker 300 indicating that the section is a section where an underground cable is installed. For example, the server 400 says through the speaker 300, “This area is an area where underground cables are buried. Prior approval from KEPCO is required for excavation work. You can encourage people to avoid unauthorized excavation by outputting warning sounds such as “If unauthorized excavation occurs, safety accidents may occur and recovery costs will be charged.”

Meanwhile, when determining whether or not to carry out excavation work in the section where the underground cable is installed based on the received vibration signal, the server 400 uses deep learning technology to learn the vibration signal according to the excavation work and the received vibration. If a vibration signal corresponding to the vibration signal learned from the signal is detected, it can be determined that excavation work is being performed within the corresponding section.

If it is determined that excavation work is being performed in a section where an underground cable is installed, the server 400 may determine whether the excavation work is unauthorized excavation work. According to one embodiment, the server 400 determines whether excavation work is planned in the section based on previously stored excavation plan information, and if no excavation work is planned in the section, the excavation work is unauthorized excavation. It can be judged to be work. In other words, the server 400 can determine whether the excavation work is unauthorized by determining whether the excavation work is planned in the corresponding section.

The excavation plan information may include excavation information (expected excavation date, excavation time, excavation scale, etc.) planned in the section where the underground cable is installed, and the corresponding information may be stored in advance in the server 400. The server 400 may determine that an excavation operation is planned if an excavation operation is scheduled within a preset standard time from the time at which the excavation operation is determined to be in progress, and may determine that the excavation operation is not an unauthorized excavation operation. there is. Meanwhile, the server 400 determines that the excavation work is not planned if the excavation work is not scheduled within a preset standard time from the time it is determined that the excavation work is being performed, and determines that the excavation work is unauthorized excavation work. You can judge.

If the excavation work is determined to be unauthorized excavation work, the server 400 may output a warning through the speaker 300. According to one embodiment, the server 400 may output a second warning through the speaker 300 urging the cessation of unauthorized excavation work. In other words, the server 400 can induce unauthorized digging to stop by outputting a warning sound urging the user to stop unauthorized digging.

If it is determined that the excavation work is unauthorized, the server 400 may transmit the received video and the location of the corresponding section to a pre-registered user terminal. That is, the server 400 can transmit the video and location of the section to a user terminal owned by the manager of the section and inform the manager of the fact. The server 400 may have the location of the camera 100 or the location of the vibration detection sensor 200 stored in advance, and the location of the camera 100 or the location of the vibration detection sensor 200 may be stored in the section where the underground cable is installed. It can be used as a location.

On the other hand, when it is determined whether or not to carry out excavation work in the corresponding section based on the received vibration signal, the server 400 captures an image of the section through the camera 100, and the captured image, the received vibration signal, and the corresponding The location of the section can be transmitted to a pre-registered user terminal. If the section where the underground cable is installed is not suitable for installing the camera 100, the operation of taking images of the section through the camera 100 may be omitted. If it is determined that excavation equipment exists in a section where an underground cable is installed, the server 400 may transmit the received video and the location of the section to a pre-registered user terminal.

After outputting the second warning, the server 400 can determine whether to stop the unauthorized excavation work. The server 400 may determine whether unauthorized excavation work has been stopped after a predetermined time has elapsed from the time the second warning was output. The server 400 can determine whether unauthorized excavation work has been stopped by determining whether or not excavation work is performed within the section where the underground cable is installed using the same method as the above-described method.

If it is determined that the unauthorized digging operation has not been stopped, the server 400 may output a third warning, which is a higher level warning than the second warning, through the speaker 300. According to one embodiment, the third warning may be a warning sound with a higher volume than the second warning. According to another embodiment, the third warning may be a warning sound with different content than the second warning.

As described above, the present invention can prevent damage to the underground cable due to unauthorized digging by outputting a warning when unauthorized digging occurs in a section where the underground cable is installed.
