Description

IP Device for Video Surveillance of Power Facilities

The present invention is installed in substations, etc. to support CCTV that monitors power facilities of the site in high definition, and relates to an IP device for video monitoring of power facilities with multi-function.

The security equipment installed at the substation for monitoring power facilities has been in operation for more than 10 years and has become obsolete. In particular, if you look at CCTV mainly, 400,000-pixel SD-level low-quality cameras account for the majority. In the case of substations built a long time ago, a coaxial cable (or STP cable) is still being used as a transmission medium between the on-site camera device and the substation monitoring room camera monitor device. On the other hand, in the case of a new substation, a high-definition camera of 2 million pixels or more that reflects the latest technology is installed, and optical cables are mainly used as the transmission medium.

Users are demanding high-definition camera images for image analysis, failure prediction, and precise facility monitoring. Therefore, it is necessary to replace the SD-level low-quality camera that has reached the limit of use with an HD-level high-definition camera. In order to do this, it is necessary to precede the construction of replacing the previously installed coaxial cable with an optical cable, which requires a huge cost. Therefore, it is not realistically easy to improve an SD-level low-quality camera into an HD-level high-definition camera.

In addition, users can use high-definition cameras to implement AI functions such as real-time facility status check or failure prediction using image information that could not be implemented before, or to link various sensors with cameras to monitor facilities in various ways and strengthen security monitoring. Requests for additional functions are increasing.

In the above-mentioned situation, the following difficulties exist from the viewpoint of constructing a video surveillance system for power equipment that is integrated and managed in the ICT room.

First, a considerable cost is required to demolish the old coaxial cable or STP cable installed and newly build an optical communication network or high-speed IP communication network.

Second, the specifications of CCTVs that are already installed or planned to be installed at the monitoring target site are diverse, the types of additional sensors installed in each monitoring target site are also diverse, and audio output is also performed depending on the site, so integrated management in the ICT room The following is not easy from a protocol processing point of view.

Third, in the case of a device installed on a site to be monitored, if a failure occurs, the device must be separated and stored as a whole in order to identify the cause and take action. do.

The present invention converts the power facility monitoring video to high-definition at low cost by using the existing coaxial cable (or STP cable) as it is, and in addition, it is a 'power Multifunctional IP device for high-definition video surveillance of facilities is presented.

Prior to the description of the present invention, as an example of a field to which the present invention can be applied, the security/equipment monitoring field of an unmanned substation will be described from the conventional system.

1 to 3 are conceptual views illustrating a system configuration of security/equipment monitoring of an unmanned substation according to the prior art.

The unmanned substation integrated security system constructed for security monitoring and facility monitoring of unmanned substations is largely divided into the first generation shown in FIG. 1, the second generation shown in FIG. 2, and the third generation shown in FIG. The first generation is an analog method having only an analog camera 10 and a field control device 401, the second generation is a hybrid method having both analog and IP methods and a recording device 402, and the third generation is an IP optical network It is an IP method in which an image is transmitted from the IP camera 20 to the recording server 403 through optical communication using

The first generation is an analog method, and it is an old facility for more than 10 years, and there are problems in that it is difficult to additionally apply a coaxial cable and a decrease in monitoring efficiency due to malfunction and SD low quality. The second-generation camera 10 provides an analog-type SD image low-quality service, but additional expansion is a waste of budget, and a mixed operation of high-definition and low-quality images is impossible. In addition, the 3rd generation secured sufficient transmission speed of high-definition images using optical communication networks, but it is not easy to apply new technologies such as AI and IoT sensors.

As an unmanned security system, the structure of CCTV image data transmission is shown in Table 1 below.

In the case of first-generation devices, some systems have been in use for more than 17 years, so frequent failures and remote monitoring efficiency are lowered. In addition, converting the 1st and 2nd generation low-resolution methods to 3rd-generation high-definition IP methods has problems such as high cost and long work time, such as truce work, because existing coaxial cables must be removed and optical cables installed. The transition to a new generation is not easy.

The problem that occurs in such a situation is that there is a limit to high-quality service using video. It is difficult to provide value-added services using image analysis and artificial intelligence. The system is complicated between the devices installed in the communication room and the terminal devices installed in each room of the substation, and the system is different for each household, making it impossible to provide wireless IoT services. Also, the cost of improving the image quality is excessive. For example, it is estimated that the cost of converting all the first-generation unmanned substation security systems to the third-generation is about 84.2 billion won [(200 million won of facilities + 50 million won of demolition) × 337 places]. Even if it costs so much, the period of transitioning generations is too long. In order to change the generation, the existing coaxial cable must be demolished and a new optical cable must be installed. Moreover, security monitoring and facility monitoring are not possible during the work period, and safety accidents are a concern.

Therefore, when converting pre-installed equipment to the 3rd generation method for the 1st and 2nd generation methods, it is possible to reduce costs by using mechanical shaft materials (coaxial, STP cables) to reduce costs rather than dismantling all of them. A method is required, and a method for securing flexibility to apply advanced additional functions and/or various sensors is also required.

Next, we will look at the power facility video monitoring system of the integrated management method in the ICT room to be built using the IP device for video monitoring of power facilities according to the spirit of the present invention.

In improving the low-quality surveillance cameras and aging security monitoring facilities of the unmanned substation integrated security system, the existing infrastructure network, coaxial cable (or STP cable), is used to reduce facility costs, shorten the facility period, and connect with various communication methods. Ha, devised and applied 'multifunctional IP device for high-definition video monitoring of power equipment'.

The on-site control device (or recording device) of the unmanned substation integrated security system is installed in the communication room (or ICT room) of the substation, and security monitoring facilities such as cameras and sensors are installed in each room of the substation (ie, the monitoring target site side). To install, these two devices (or equipment) communicate by connecting them with a coaxial cable (or STP cable).

In order to convert the existing analog monitoring facilities and infrastructure to the IP method, instead of installing a new optical cable, by using the existing analog (coaxial, STP, control) cable, the video transmission method is converted to the Ethernet method, broadcasting transmission, sensor signal collection and It was designed to integrate security monitoring facilities such as lighting control into a multi-functional IP device installed in each room of the substation.

5 is a conceptual diagram illustrating a multifunctional power facility video monitoring system implemented in a digital IP method using an existing coaxial cable and a multifunctional IP device for video monitoring of power facilities of the present invention.

The multifunctional IP device 100 for power facility video monitoring of the present invention supports wired communication and wireless communication in one device, and supports IP communication using existing coaxial cables, STP cables or optical cables, and secure wireless Wifi communication and It supports low-power Bluetooth BLE communication. In this way, the recording device 500 may collect monitoring information such as video information of the IP camera 20 through the multi-function IP device 100 . In addition, the facilities 27 , 28 , and 29 that had to be individually built for each function can be integrated into a single device.

The multi-function IP device 100 may be installed in each room (target site) of the substation and a corresponding IP communication device may be installed in the communication room (ICT room) to communicate. The multi-function IP device 100 to be installed in a substation may be installed as a single type, or may use a group type in which several are bundled into one.

6 is a comparative conceptual diagram showing the improvement effect of the multi-function IP device for video monitoring of power equipment of the present invention supporting multi-function. As shown, monitoring facilities such as power, surge, broadcasting, lighting, and sensors are individually installed in the enclosure provided in each room (target site) of the existing substation, so space is insufficient and management is difficult. It can provide integrated functions based on device installation, which frees up space and is easy to manage.

7 is a conceptual diagram illustrating functions that can be added to the multifunctional IP device for video monitoring of power facilities of the present invention.

According to the implementation, the multifunctional IP device for video monitoring of power facilities of the present invention is a modular type equipped with embedded S/W to enable connection with video analysis, IoT connection, and SCADA event processing for power facilities so that various new functions can be applied. It can be installed additionally.

In addition, as illustrated, the audio board 150 may further include an audio board 150 as a human interface board that provides auditory or visual analysis results of monitoring information to a user of the monitoring target site.

The bus controller may be implemented as a dedicated chip for controlling a bus, and the power supply and surge protection circuit unit may be implemented with a well-known AC/DC converter and a well-known surge protection means.

The bus controller and the power supply and surge protection circuit unit 200 may be implemented on the main board of the multi-function IP device 100 for video monitoring of the power equipment, and an expansion slot for physically attaching and detaching the expansion boards to the expansion buses. may also be implemented on the main board. In this case, the sensor reception board 140 , the signal processing board 120 , and the data transmission board 160 function as expansion boards detachable from each of the expansion slots.

When the multifunctional IP device 100 for video monitoring of power equipment is attached to the wall of the protection enclosure, the sensor receiving board, the sensor receiving board 140, the signal processing board 120 and the data transmission board 160 It is preferable in terms of convenience of maintenance to be implemented in the form of being fitted from the front. In this case, terminals to which various conductive wires can be connected on the sensor receiving board 140 , the signal processing board 120 , and the data transmission board 160 are also preferably arranged in a form that can be connected from the front side. do.

To summarize the above, the sensor receiving board 140, the signal processing board 120, and the data transmission board 160 are parallel to the expansion bus on the front part of the IP device for video monitoring of power equipment. It is fixed in a state connected to the poles, and in the fixed state, terminals for connecting an external conductor are exposed on the front part. The same is true for the audio board 150 and the video input board 170 .

Looking at the configurations arranged on the front part for the convenience of the corresponding operation, all the expansion boards 120 , 140 , 150 , 160 , 170 each use the corresponding expansion board as the function of the multi-function IP device 100 for video monitoring of power facilities. and fastening operation screws (121, 141, 151, 161, 171) for coupling to the protective enclosure. After turning each of the fastening operation screws 121 , 141 , 151 , 161 , and 171 , the corresponding expansion boards 120 , 140 , 150 , 160 , and 170 can be separated by pulling them.

In addition, as shown, dip switches 144 for adjusting various sensors are disposed on the front part of the sensor receiving board 140, and on the front part of the signal processing board 120, such as Wifi or Bluetooth. An antenna connection terminal 124 for short-range wireless communication is disposed, an amplifier volume 154 for adjusting audio output is disposed on the front part of the audio board 150 , and a coaxial cable is disposed on the front part of the data transmission board 160 . A connection terminal 164 may be disposed, and video input terminals 174 may be disposed on a front portion of the video input board 170 .

Although the drawing includes the audio board 150 as the human interface board, in other implementations, it may be replaced with a video output board or an audio/video output board for providing, for example, image analysis information to a target site manager.

9A to 9C illustrate data transmission boards that can be selectively mounted in an expansion slot according to a wired data transmission line. 9A is a coaxial cable data transmission board 160 shown in FIGS. 8A to 8C, and FIG. 9B is an STP cable data transmission board 160-1 using an STP cable as a data transmission line, and an STP cable connection slot 164-1. ), and FIG. 9c is an optical cable data transmission board 160-2 using an optical cable as a data transmission line, and includes an optical cable connection slot 164-2.

The three data transmission boards shown constitute one set (candidate set) in terms of product, and when the IP device 100 for video monitoring of power equipment is installed in the field, one can be selected to match the line used in the field. can

The data transmission board 160 may be selected and mounted in the expansion slot according to the type of the wired communication line provided from the installation site to the ICT room. Accordingly, an integrated power facility video monitoring system (integrated security system) that is easy to integrate and manage by installing the IP device 100 for video monitoring of the same type of power facility at each CCTV installation site regardless of the type of the existing wired communication line ) can be built.

Considering that wired communication lines established or installed in the future or in power facilities, in particular, substations, etc. are coaxial cables, STP cables, and optical cables, the data transmission board 160 is a coaxial cable for transmitting and receiving Ethernet packets through a coaxial cable. cable data transmission board; an STP data transmission board that transmits and receives Ethernet packets through an STP cable; and an optical data transmission board for transmitting and receiving Ethernet packets through an optical cable, one selected according to the CCTV installation site may be mounted in the expansion slot (bus). Alternatively, in the case of a site in which two types of communication lines are installed in advance, two data transmission boards may be mounted in the expansion slot (bus).

As a measure to increase the ease of inspection and action when a failure occurs during operation after being installed in the monitoring target site, in the present invention, all devices with a high probability of failure can be detached from the expansion slot (bus). It is presented in the form that exists. However, only the bus controller for smooth driving of the expansion bus is mounted on the main board, which is difficult to detach.

In particular, in general, the main CPU for operation and control of the entire device is generally mounted on the main board of the device, but in the present invention, on the signal processing board 120 detachable from the expansion slot, the power A main CPU for the IP device for facility video monitoring is arranged. This is to provide the ease of inspection and replacement of the main CPU since the failure rate of the main CPU is also significant when operated for a long time in an environment that may be poor.

However, since the main CPU is a necessary configuration for performing the basic functions of the IP device for video monitoring of power equipment, other expansion boards (data transmission board 160, audio board 150, sensor reception board 140, video input board ( 170)), if the signal processing board 120 on which the main CPU is disposed is removed while trying to separate, the inspection operation may be disturbed. In order to prevent such confusion, it is preferable that the signal processing board 120 is manufactured to have a very different (wider) area exposed to the outer surface than other expansion boards.

10B is a cross-sectional view illustrating one side of the separated signal processing board.

10C is a cross-sectional view illustrating the rear surface of the separated signal processing board.

10D is a cross-sectional view illustrating another side of the separated signal processing board.

On the other hand, the signal processing board 120 may have components that support it so that a function assigned for inspection can be performed even in a state in which the expansion slot is detached.

For this purpose, the signal processing board includes: an expansion slot connection unit 122 mounted in an expansion slot provided for the expansion bus; DC power input terminal 125 to which external DC power is applied during inspection; a USB terminal 128 that supports an inspector to perform serial communication during inspection; and a multi-purpose input/output terminal 127 for outputting a screen during inspection. In addition, a micro SD card slot 126 for mounting a micro SD card installed with an OS and an application program may be provided.

By the way, the DC power input terminal 125, the USB terminal 128; It is preferable that the multi-purpose input/output terminal 127 and the micro SD card slot 126 cannot be used in a normal state, physically mounted on the IP device for video monitoring of power equipment through the expansion slot, this For the DC power input terminal 125, the USB terminal 128; and the multi-purpose input/output terminal 127 and the micro SD card slot 126, when the signal processing board is mounted in the expansion slot, at a position not exposed to the outside of the power equipment video monitoring IP device, that is, the power It may be disposed on the outer surface of the IP device for monitoring equipment video.

The illustrated multi-purpose input/output terminal 127 is an HDMI terminal, and in other implementations, other types of terminals may be applied. For example, the DC power input terminal and the multi-purpose input/output terminal may be implemented as a DC power input terminal and a multi-purpose input/output terminal provided by a Raspberry Pi board or an Arduino board. In this case, it is possible to easily check the main CPU, etc. arranged on the signal processing board by using the Raspberry Pi or Arduino access method, which is a widely known control/check method closely related to hardware.

The multi-function IP device for video monitoring of power equipment requiring multi-function may include an antenna supporting wireless Wifi communication or Bluetooth communication and a corresponding communication module. In this case, in consideration of the easiness of inspection according to the above-described Raspberry Pi or Arduino access method, an antenna wire connection terminal for wireless Wifi communication or Bluetooth communication and a corresponding communication module may be disposed on the signal processing board 120 .

The data transmission board 160 is for performing Ethernet communication using a wired communication line provided from the monitoring target installation site to the ICT room. That is, it is possible to generate/deliver/process a TCP/IP packet by reflecting the IP assigned to the multi-function IP device for video monitoring of power equipment (more specifically, assigned to the data transmission board).

Correspondingly, the ICT room is equipped with devices that perform Ethernet communication and TCP/IP packet processing, and the integrated power facility video surveillance system (integrated security system) implemented with the above-described Ethernet communication network is a CCTV or sensor type. Even if there is a mixture, integrated monitoring and management are easily possible with the Ethernet communication protocol using the multi-function IP device for video monitoring of power facilities.
