Currently, servers that are installed to receive insurance, that is, backups, are installed for important file data that will be lost or needed again in the future. Servers also have physical capacity limitations, so several servers are operated. However, to prevent data loss, there is no clear solution on how to respond if something goes wrong with the installed server. I installed a backup server for safety, but I don't know when such a server will fail, and I may have a situation where I need to back up the data information of the backup server again.

Of course, conventionally, there are programs that enable the user to know the status of the backup server. However, these conventional programs require users to check the status by directly accessing a server PC, such as a backup server. So, if the server PC has an abnormality, the server beeps when the server beeps physically or the color of the LED changes.

However, if the user does not see or hear the notification signals, the server cannot operate normally until the user confirms. It doesn't matter if it doesn't work and refer to the data of the backup server, but if there is a problem, it can cause a lot of loss if you check the server and find out that the server has a problem.

Therefore, in order to stably manage the backup data of the production equipment in the industrial site, a more efficient management method is required when multiple backup servers are installed.

Or, it means that some or all of the components of the server device 130 may be integrated and configured in a network device (for example, a wireless switching device) in the communication network 120, in order to help a sufficient understanding of the invention It is explained as including all.

For example, the production equipment 97 of FIG. 1 may include various equipment installed in the semiconductor production line (A). In particular, in the case of a semiconductor process, the production equipment 97 may be installed in a clean room. Production equipment 97 according to an embodiment of the present invention may typically include exposure equipment. In the case of exposure equipment, it occupies the most weight in the semiconductor process and is expensive, so it needs to be strictly managed. Of course, the related data (eg driving data, etc.) also needs to be strictly managed. The exposure equipment may simply refer to a chamber that applies a photoresist (hereinafter, photo) on a wafer, applies a mask, and then exposes it to light, but refers to equipment that performs all of the above series of processes. can do. More precisely, it can be lithographic equipment. After the photo is applied and the mask is applied, it is exposed to light and etched.

ASML equipment, which occupies a 64% share in the lithography equipment industry, has a large number and large share in semiconductor fabrication (FAB), so it may be necessary to monitor and monitor backup servers specialized in ASML equipment. As it is expensive equipment, problems can occur when it is controlled by authorized personnel, ie, personnel other than the access licensor (for example, data loss), and when a shock is applied from outside the equipment, process problems can occur. In an embodiment of the present invention, in order to supplement these parts, a surveillance camera can be combined with a surveillance camera to construct a reliable surveillance monitoring system. In addition, backup data can be strictly managed.

The production equipment 97 may communicate with the monitoring device 110. For example, when remotely controlled by the user device 105, the corresponding control command is received, and the monitoring device 110 is transmitted to the production equipment 97, and the production equipment 97 can be controlled by remote control. . For example, when the server device 130 can remotely control a plurality of production equipment 97 provided in the production line through a web service by the user device 105, the user device 105 is a server device ( 130) and select the monitoring device 110 to control the production equipment 97. Since the control method of the production equipment 97 can be made in various ways, the embodiment of the present invention will not be limited to any one form.

The photographing apparatus 100 may include, for example, a CCTV camera or an IP camera, and may include a fixed camera and a PTZ camera capable of remote control. PTZ cameras are available with Pan, Tilt and Zoom functions. The photographing apparatus 100 according to an embodiment of the present invention may be installed around the production equipment 97 in a clean room where, for example, a production line (A) or a semiconductor process is performed to photograph the production equipment 97.

The photographing apparatus 100 photographs the surrounding situation of the production equipment 97 and provides the photographed image to the monitoring apparatus 110. The photographing apparatus 100 may transmit the photographed image of the production equipment 97 to the monitoring apparatus 110 through wired/wireless communication, and of course, wired communication may be desirable to secure a stable photographed image. The photographing apparatus 100 includes a communication module, and may analyze the photographed image in the process of transmitting the photographed image and provide analysis results. In this case, the imaging device 100 may be equipped with an image analysis module therein. The system design of the photographing apparatus 100 and the monitoring apparatus 110 may be variously performed according to a designer's intention.

In an embodiment of the present invention, as a photographing device 100, two CCTV cameras can be installed and installed, and two CCTV cameras can be supplied with power through POE (Power over Ethernet) of a monitoring device 110 such as a PC. , The captured image may be configured to be reproduced in the monitoring device 110.

The user device 105 includes various devices such as a desktop computer, a laptop computer, a tablet PC, and a smart phone. The user device 105 can access the backup device 140 through the monitoring device 110 or the server device 130 through a network such as the Internet protocol, through which the production equipment 97 or the backup device 140 is connected. Control. For example, the user device 105 and the monitoring device 110 may be operated based on a KVM (Keyboard Video Mouse) system. Here, since the KVM is an interface in which the monitoring device 110 is formed with a user, an interface by voice commands may of course be possible. The KVM system is installed in the monitoring device 110, and the user device 105 can perform a control operation using a program (eg, an application) interworking with it. Accordingly, the user device 105 can freely view the real-time process screen anywhere and control. That is, the embodiment of the present invention directly creates a virtual KVM environment or a KVM-based virtualization environment to create the same conditions as when a KVM external device is connected.

In addition to being able to remotely control the monitoring device 110 by connecting the user device 105 to the server device 130 according to an embodiment of the present invention, operating data and/or an internal chamber associated with the production equipment 97 In addition, an alarm related to monitoring of the backup devices 140 in which data related to a process performed in the backup is stored may be received. The interface design can simply provide the necessary information. If a problem occurs, you will be able to check the alarm, user registration, user notification settings, notification cycle, error log, and error checking information. Of course, monitoring of the backup devices 140 is performed by the server device 130 interlocking with the plurality of backup devices 140, and the user device 105 may be a portable terminal device such as a smartphone of a backup data manager.

For example, the user device 105 selects the backup devices 140 as a server PC, which is to be monitored for backup, sets it as a target PC, installs the server down monitoring system software, and then installs the server PC backup device 140 ) Enter the network IP address of the PC of the server backup monitoring system so that they can exchange information with each other over the network. In other words, through the user device 105, for example, the user can set and operate the system to centrally monitor the backup devices 140 in the server device 130, but the backup device is set as a target. By performing communication in the same way as the Internet of Things (IoT) between 140, for example, one backup device 140 may notify the server device 130 as a representative device. In this way, the user can set various operations of the system for the operation of the backup device 140 through the user device 105.

The monitoring device 110 may be connected to the production equipment 97 and installed in the surroundings. The monitoring device 110 may include a computer (PC) or separately manufactured kiosk type equipment. Of course, the monitoring device 110 may also function as an image distributor. Through this, the image photographed by the photographing apparatus 100 is transmitted to the server apparatus 130, and the control is performed by the user apparatus 105 for remote control of the production equipment 97 and the like. Therefore, the monitoring device 110 may be referred to as a distribution device or a relay device.

The monitoring device 110 performs a real-time monitoring operation in order to quickly cope with measures for mistakes and malfunctions, even if a problem occurs in the semiconductor manufacturing site. For example, the monitoring device 110 is equipped with a function to detect when a singularity occurs in the monitoring screen of a semiconductor equipment process in real time, and shows the user with the specifics, and even when monitoring in real time through screen recording The screen is played again to show the detected screen again. Furthermore, it monitors the surroundings of production equipment (97) in real time through the video provided by the CCTV cameras around production equipment (97) and matches the time record when the singularity of production equipment (97) occurred through the CCTV camera recording function. You can trace and analyze the cause.

The monitoring device 110 receives a real-time screen of the production equipment 97, that is, a photographed image, from the photographing device 100 by hardware (H/W). In addition, a software (S/W) program is built in the monitoring device 110 to build a program capable of monitoring the production equipment 97, particularly ASML's exposure equipment, and executes it. In the embodiment of the present invention, it can be referred to as an ASML monitoring program in that it is a program for monitoring equipment of a specific manufacturer. The monitoring device 110 is a user device 105 possessed by an administrator who manages a production process, and may store and provide a program (or application) capable of providing a user UX/UI. Of course, such a program may be provided through the server device 130. The monitoring device 110 may have a recording system computing function that receives a video signal, that is, a video signal provided by the photographing device 100 or the production equipment 97. In order to receive a video signal, the monitoring device 110 may include a video capture card. Various types of digital or analog signals can be processed according to the type of video signal, and in the embodiment of the present invention, a video capture card capable of receiving a digital signal can be provided.

The monitoring device 110 stores the video signal of the production equipment 97, that is, the photographed image in real time, detects and changes the process progress screen due to a change from the normal screen, that is, a user or an unexpected event. It can be regarded as and stored in the form of a list. To this end, the monitoring device 110 may also classify event events through a deep learning method using the accumulated data through an image search algorithm that analyzes stored video records. In addition, by prioritizing and classifying the importance of the occurrence of an event, the user can respond quickly. Through the recorded event notification function, it is possible to mark the time of occurrence of a problem and quickly access the past records. Furthermore, the monitoring device 110 may provide a desired screen by designating a desired time as well as an event that has occurred.

For example, the monitoring device 110 may perform a data construction operation and allow a search operation to be performed based on this. In other words, when the system is established, the monitoring device 110 acquires a still image in the most stable state of the production equipment 97 through learning of the captured image received from the imaging device 100. In other words, since 30 still images are received per second, it is to acquire a still image in a stable unit frame based on the analysis result through image analysis. This may be set as a reference image of production equipment 97, that is, reference data. When the setting of the reference data is completed, the monitoring device 110 may determine whether the production equipment 97 is abnormal by comparing the received image with the set reference data. For example, when a specific person is photographed together, the analysis result of the person image may be compared with pre-stored permission information to determine whether permission is granted. If an event occurs in a specific video section in this process, the captured video of the corresponding section, that is, a plurality of unit frame images corresponding to a certain time section is secured, and additional information such as date and time information is matched at this time. Can be saved. Accordingly, the administrator can easily search for an event generated in the corresponding date or time zone by simply inputting date or time information when searching for a specific video. In the above processes, as the data is accumulated, deep learning of the accumulated data can be performed to perform a more accurate and precise operation.

In addition, the monitoring device 110 directly captures and records the monitoring screen of the production equipment 97. Since the output signal is sent back to, for example, a PC and a device monitor constituting the monitoring device 110, it may perform the function of an image distributor. The monitoring device 110 recognizes a screen and captures it when a specific change occurs to provide an alarm function. It can also perform digital video recording function to record video such as CCTV camera. In addition to simply viewing the screen, a KVM can be implemented to control the screen of the device with a keyboard mouse. Through the alarm function that has occurred, you can view the record of the event, select a desired time, play partly, and edit the video, making it possible to produce it as an educational sample.

In summary, the monitoring device 110 analyzes the reproduced image and provides an alarm function. It analyzes video signals of semiconductor equipment to define patterns for specific movements as errors or events, and informs the user to know the time when the singularity (or singularity) of the process screen of the equipment occurred. In addition, by grasping the time that occurred, the user can accurately analyze the problem and prevent or educate. It saves the pattern of the normal screen and uses the result as a sample to notify the event when a movement different from the normal pattern occurs as an event. An image processing algorithm is implemented to reduce the range of errors, and a clear image can be provided through screen compression. When such image processing data is accumulated, it can be efficiently managed by a deep learning method.

The communication network 120 includes both wired and wireless communication networks. For example, a wired/wireless Internet network may be used or interlocked as the communication network 120. Here, the wired network includes an internet network such as a cable network or a public telephone network (PSTN), and the wireless communication networks include CDMA, WCDMA, GSM, Evolved Packet Core (EPC), Long Term Evolution (LTE), Wibro network, etc. It includes meaning. Of course, the communication network 120 according to an embodiment of the present invention is not limited thereto, and may be used as a cloud computing network under a cloud computing environment, a 5G network, etc. as a connection network of a next-generation mobile communication system to be implemented in the future. For example, when the communication network 120 is a wired communication network, an access point in the communication network 120 may access a telephone exchange or the like, but in the case of a wireless communication network, data may be accessed by accessing a SGSN or a Gateway GPRS Support Node (GGSN) operated by a communication company. The data can be processed by accessing various repeaters such as BTS (Base Station Transmission), NodeB, and e-NodeB.

The communication network 120 may include an access point. Access points include small base stations, such as femto or pico base stations, which are often installed in buildings. Here, the femto or pico base station is classified according to the maximum number of monitoring devices 110 connected to the classification of the small base station. Of course, the access point includes a monitoring device 110 and a short-range communication module for performing short-range communication such as Zigbee and Wi-Fi. The access point can use TCP/IP or RTSP (Real-Time Streaming Protocol) for wireless communication. Here, short-range communication may be performed in various standards such as radio frequency (RF) and ultra-wideband communication (UWB), such as Bluetooth, Zigbee, infrared (IrDA), ultra high frequency (UHF), and very high frequency (VHF), in addition to Wi-Fi. Can be. Accordingly, the access point can extract the location of the data packet, designate the best communication path for the extracted location, and forward the data packet to the next device, for example, the server device 130 along the designated communication path. An access point can share multiple lines in a typical network environment, including routers, repeaters, and repeaters.

The server device 130 includes a DB 130a, and may simply act as a digital video recorder (DVR). Of course, it is preferable that the server device 130 according to the embodiment of the present invention performs a monitoring operation for monitoring the (backup) server (shutdown) as shown in FIG. 2. The server device 130 receives data from the monitoring device 110 provided in the production line A such as a clean room and stores it in the DB 130a, or at least one backup device 140 without the DB 130a. ) To save the backup data. The server device 130 and the backup device 140 may be connected to each other through an internal network, that is, an intranet. In the server device 130 and the plurality of backup devices 140 according to an embodiment of the present invention, the server device 130 may serve as a kind of host, and the backup device 140 serves as a storage. It can be done. Accordingly, the backup devices 140 may have the same structure as a storage redundancy device in a storage area network (SAN) network environment connected by a switch (eg, a hub, etc.).

The server device 130 may use an external web server operator's service (eg, Amazon web service, etc.) as viewed from the industrial site, but in the case of semiconductor manufacturers, the server is operated and monitored internally. Managing data on the production line (A) is beneficial in many ways. This is because it is possible not only to freely manage the data, but also to quickly restore it through backup data previously stored when a problem occurs in the production equipment 97 of the production line A. Since data of the production equipment 97 may be lost due to various factors of the industrial site, data access must be facilitated for rapid restoration.

Furthermore, the server device 130 may classify and store a captured image, that is, a video signal provided by the monitoring device 110 and store various other data. In addition, the server device 130 may include a backup program for recording a monitoring program. The server device 130 may be configured based on Linux, because it is more reliable than a Windows-based PC and is stable in operating the server. Of course, it will not be specifically limited to Linux. Data may be stored in the DB 130a through the server device 130 to provide a more stable system according to an embodiment of the present invention.

The server device 130 stores the reference value related to the resource state of the backup device 140 and compares it with the status information of the backup device 140 received in real time, and the manager's management PC accessing the result to the server device 130 For example, it can be provided in real time to a desktop PC. In this process, for example, an abnormal state may be notified, and a notification may be made again to the user device 105 such as the manager's smartphone according to whether the abnormal state has been confirmed by the manager. In this case, the notification message may be processed in cooperation with the auxiliary device 145. Typically, text messages can be sent in conjunction with an SMS server.

The backup device 140 may be composed of, for example, a plurality of backup servers, and may store and store data provided by the server device 130. Backup is necessary for stable system operation. 2, each backup device 140 may be equipped with a monitoring program for monitoring the state of the server itself. As mentioned above, when the user sets or selects the target server PC, that is, the backup device 140 through the user device 105, the program installation may be limited to the selected backup device 140. The server device 130 may notify the user device 105 when instability is detected, for example, when status information related to the monitoring state is provided from each backup device 140 or from a representative backup device 140 representing a group. can do.

The backup device 140 may provide status information on internal hardware or software resources to the server device 130. This can be useful for protecting backup data. For example, monitoring factors may include CPU usage, memory usage, HDD usage, network disconnection, or slowdown, service port status, and the like.

The auxiliary device 145 may be a communication channel of various types for notifying the user device 105 when an abnormality is detected as a result of monitoring of the backup devices 140 in the server device 130. Here, the communication channel includes a server for transmitting the status of the backup devices 140 in the form of a text message (SMS), email, and the like, as shown in FIG. 2. For example, since the server device 130 pre-stores contact information (eg, phone number, e-mail information, address information, etc.) of the administrator's user device 105 for the specific backup device 140 to be monitored, The notification is notified to the auxiliary device 145 while providing the contact information.

Looking more closely, servers are currently being installed for insurance, that is, backups of important file data that will be lost or needed again in the future. However, since servers also have physical capacity limitations, several servers are operated. However, if there is something wrong with the installed server to prevent loss, it is necessary to quickly respond to it. In an embodiment of the present invention, a backup server is installed for a safety device. For example, when an abnormality occurs in the installed backup server, a situation in which data information of the backup server must be backed up may occur. Therefore, in the embodiment of the present invention, when a problem with the backup server currently in operation occurs, a notification is provided so that the user can immediately cope with the data loss of the server and do not have to worry about backup of the backup server. If you have a system running multiple servers, a server down monitoring system may be necessary. It is possible to check the status of several servers in real time, and if it is not normal, it is notified to provide information so that the user can know quickly.

In summary, recently, data backup servers are frequently used in case data is erased due to worry of data loss or data cannot be viewed due to a sudden accident. And such a backup server also provides a backup solution to operate without problems. However, a lack of such a backup solution may require a server backup monitoring system as in the embodiment of the present invention to compensate for a case where the backup solution is not executed or the user is not aware and left unattended. Server PCs for server backup monitoring For example, a backup server can be used without limitation if it can be accessed through a network connection. Select server PCs you want to monitor for backup and set them as target PCs to install the server down monitoring system software. Server PCs can send and receive information to each other by entering the network IP address of the PC of the server backup monitoring system. Monitoring elements include CPU usage, memory usage, HDD usage, network disconnection or slowdown, and service port status. If any of these changes due to an abnormality compared to the stored reference value, the monitoring server, that is, the server device 130 of FIG. 2 recognizes the state change. The PC of the server down monitoring system, that is, the server device 130 may transmit a notification to a user by itself or provide a notification to a mobile device through another server PC (for example, a field system PC).

The mobile device can be registered and used as an information device desired by the user by using a portable phone, a tablet PC, a pager (phone), an email, and other multi-devices as the user device 105 of FIG. 1. It is accessed through a web server and in the server down monitoring system, the status of the servers enables the user to be monitored through a monitoring interface composed of an XML-based information table. The design of the interface is simple and it is enough to provide the necessary information. When a problem occurs, you can check the notification, user registration, user notification settings, notification cycle, error log, and error confirmation information. The user can view the server backup monitoring system anytime, anywhere by entering the IP address of the server backup from an unspecified PC connected to the network.

The reason for installing the backup server as in the system 90 according to the embodiment of the present invention is to not lose necessary information. For this reason, backup servers are usually built to prevent data loss. If the data of the semiconductor equipment or other devices that were operating due to unintended phenomena disappears and are not ready for operation, it will be possible to prevent the loss of productivity by finding and restoring the desired data from the designated backup server.

Above all, the server down monitoring system 90 according to the embodiment of the present invention will be used in an industry that requires a lot of data. In particular, it will be widely applied in semiconductor industry equipment that requires large amounts of data and large numbers of calculations. It can provide convenience to users by using the server PC status transmission and mobile device notification delivery functions.

The communication interface 300 may communicate with the monitoring device 110 of FIG. 1 and a plurality of backup devices 140. Since the monitoring device 110 uses an external network operated by a communication company, various operations such as modulation/demodulation, encoding/decoding, muxing/demuxing, and scaling can be performed. For example, the communication interface unit 300 receives the operation data or operation data of the production equipment 97 from the monitoring device 110 from the server device 130 and stores it in the DB 130a, and then forms a backup data. Can be managed by Accordingly, for example, when the data of the production equipment 97 of the production line A disappears and is not ready for operation, it is possible to find and restore desired data from a designated backup device (eg, backup server) 140. .

In this process, the communication interface 300 may communicate with a plurality of backup devices 140 through an internal network such as an intranet. Of course, the server device 130 and the backup device 140 share each other's address information (for example, a network IP address, etc.), and can communicate with each other through this. For example, if there is a request to restore the lost data to the production equipment 97 of the production line A, request the backup data to the backup device 140 that manages the data of the production equipment 97 and transmit it. Will be able to.

The control unit 310 is in charge of the overall control operation of the communication interface unit 300, the backup monitoring unit 320 and the storage unit 330 constituting the server device 130 of FIG. For example, the control unit 310 may store the setting values related to the normal state of the backup device 140 in the storage unit 330. Then, the control unit 310 receives the status information of the backup device 140 received through the communication interface unit 300 and compares it with the set value stored in the storage unit 330 to change the state of the backup device 140 Judge. Of course, such a determination operation may be performed by the backup monitoring unit 320, but it is not limited to any one form in the embodiment of the present invention as it can be performed by the control unit 310.

In addition, the controller 310 may perform an operation to enable selective backup monitoring of the backup device 140. For example, if there is a selection of the backup device 140 for monitoring from the user device 105 of FIG. 1, the backup device 140 is installed by installing a backup program for backup monitoring, that is, a solution, to the corresponding backup device 140 Status information in real time. Here, "real-time" means that data is continuously provided.

Furthermore, the control unit 310 may notify the administrator (or user) when a state change is detected in an arbitrary backup device 140 or an abnormal state is detected, for example, at the request of the backup monitoring unit 320. . Here, the administrator means a user who manages the backup device 140. Normally, when the server operation is entrusted to an external company, the server operator can manage the backup device 140, and the server device 130 can also be managed, but this is limited when the service fee is paid. It can be done, especially in the case of companies that process large amounts of data such as semiconductor processes. In this regard, semiconductor companies may have a manpower to manage the server device 130 or the backup device 140 that stores and backs up data of the production equipment 97 of the production line A. . Therefore, the person, that is, the manager can determine the status of the server device 130 or the backup device 140 in real time through a separate desktop PC or a monitoring electronic board in the company, but if a notification related to the abnormal state is received from the PC, When it is determined that it has not been confirmed, a re-notification related to the abnormal state of the specific backup device 140 may be performed with a separate portable terminal device such as a manager's smartphone.

The backup monitoring unit 320 allows a plurality of backup devices 140 to be selectively selected, i.e., partially or entirely selected, to be monitored, and in emergency situations such as data loss, data is automatically backed up to another backup device 140. It may also perform an operation such as. Of course, since the operation of backing up again takes a lot of time, it may be desirable to copy and store only data that may be lost. Since such an operation can be performed in any number of ways depending on what function is designed to be performed in the backup solution, the embodiment of the present invention will not be limited to any one form.

The backup monitoring unit 320 automatically installs a backup solution for monitoring backup to the backup device 140 based on the corresponding user command when, for example, the backup device 140 for monitoring is selected from the user device 105 of FIG. 1. Through this, information on the state of the backup device 140 may be received in real time. And, by comparing the received state information and a predetermined set value, it is possible to detect whether there is a state change in the backup device 140 requested by the user. For example, such a state change can simply compare data with each other based on a rule-based stored policy, and notify an administrator that the state is abnormal according to a comparison result, but perform an operation such as deep learning through an artificial intelligence program. You can also notify with increased accuracy. Since the rule base is to inform true or false according to a predetermined rule, that is, the artificial intelligence can be considered to be different in that it can notify the prediction result.

For example, the backup monitoring unit 320 may typically monitor CPU usage, memory usage, HDD usage, network disconnection, speed drop, service port status, etc. as monitoring elements of the backup device 140. Accordingly, if the situation is determined by comparing each of these factors based on a rule, in the case of artificial intelligence, it is possible to comprehensively determine these factors to predict and determine the state of the backup device 140. For example, it is possible to derive data related to the correlation between each factor and utilize it. For example, it is possible to predict or grasp the cause of whether the speed drop is temporary or persistent, and respond accordingly.

The storage unit 330 may store setting values for comparing the state change of the backup device 140. The stored setting value may be output according to the request of the control unit 310 and provided to the backup monitoring unit 320.

Meanwhile, as another embodiment of the present invention, the control unit 310 of FIG. 3 includes a CPU and a memory, and the CPU and the memory may be configured by one chip. The control unit 310 may include a control circuit, an operation unit (ALU), a command analysis unit, a registry, and the like, and the memory may include a RAM. The control circuit may perform a control operation, the arithmetic unit may process binary bit information, and the command interpreter may interpret input binary information. Here, the analysis may be that the control circuit searches for data on the right based on the left data and performs an operation after matching the data on the left and right on the lookup table LUT. The registry is involved in software data storage. According to the above configuration, the CPU can rapidly increase the data processing speed by copying and loading the program of the backup monitoring unit 320 into the memory when the server device 130 is initially driven.

4 is a flowchart of a server down monitoring method according to an embodiment of the present invention.

Referring to FIG. 4 together with FIG. 1 for convenience of description, the backup device 140 according to an embodiment of the present invention stores backup data related to equipment devices (eg, production equipment) at an industrial site, and stores the stored backup data. The resource state for protection is checked (S400). Here, the resource state may mean a state of hardware or software, but may specifically include CPU usage, memory usage, HDD usage, network disconnection, slow speed, and service port status.

In addition, the server device 130 installs a backup monitoring solution on at least one backup device 140 selected based on a user command of the backup data manager to perform backup monitoring, and receives from the backup device 140 where the solution is installed. An abnormal state of the backup device 140 may be detected based on the status information to be notified to a portable terminal device (eg, a smart phone) of the backup data manager (S410). For example, after real-time status is notified to the administrator's desktop PC or the monitoring billboard, when it is determined that there is no confirmation from the administrator, it can be transmitted to the portable terminal device.

Of course, various settings may be made with respect to backup monitoring of the backup device 140. For example, in certain situations, re-notification may not be performed by the administrator's portable terminal device. As an urgent situation, it may mean that the data of the production equipment 97 provided on the production line A is erased or the data cannot be viewed due to a sudden accident. When data is erased, it may occur due to a mistake of workers monitoring the production equipment 97 on the production line. Or, in the case of an accident, it may be assumed that the operation data is lost due to an instantaneous failure of the equipment. Therefore, in the case of important data, it is possible to minimize the damage that can occur in the industrial site by performing data protection in double or triple.

Therefore, when data is backed up and stored in the backup device 140, it may be possible to back up data based on the grade of the data. For example, when the user determines that the operation data of the production equipment 97 is the most important, if this is specified, the server device 130 may store the backup in consideration of the risk when backing up the data. However, when the corresponding data is backed up and stored, a backup device 140 having the most available free space among the plurality of backup devices 140, that is, a lot of idle space, such as a CPU or memory, is selected to perform a backup for specific data. You could do it.

In addition to the above, the server down monitoring system 90 according to an embodiment of the present invention can perform various operations, and other detailed contents have been sufficiently described above, and thus, the contents thereof will be replaced.

On the other hand, even if all components constituting the embodiment of the present invention are described as being combined or operated as one, the present invention is not necessarily limited to these embodiments. That is, within the scope of the present invention, all of the constituent elements may be selectively combined and operated. In addition, all of the components may be implemented by one independent hardware, but a part or all of each component is selectively combined to perform a combined function of some or all functions in one or a plurality of hardware. It may be implemented as a computer program having a. The codes and code segments constituting the computer program can be easily deduced by those skilled in the art of the present invention. Such a computer program is stored in a computer-readable non-transitory computer readable media and read and executed by a computer, thereby realizing an embodiment of the present invention.

Here, the non-transitory readable recording medium means a medium that stores data semi-permanently and that can be read by a device, rather than a medium that stores data for a short time, such as registers, caches, and memory. . Specifically, the above-described programs may be stored and provided on a non-transitory readable recording medium such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM, and the like.
