1 and 2 , the SOE system includes an SOE station 100 and a host server 200 . In addition, the SOE station 100 and the host server 200 may be connected to each other on a control network, which is a wired network, to transmit/receive data.

The SOE station 100 is composed of a redundant power supply, a CPU, and a DIM (Digital Input Module) board, and collects major digital data (event data) affecting system control at high speed, including the occurrence time and sequence of event data. SOE data is generated in millisecond units and stored in a file format.

At this time, the SOE station 100 sequentially stores COS (Change of Status) from file 1 (F1) and a predetermined time (eg, 10 seconds) elapses or a predetermined number (eg, 1000 COS) is input. When done, "Information XR (Extended Reports)" is transmitted to the host server 200 . In this case, "Information XR" is a notification data signal for notifying that the SOE data file to be transmitted by the SOE related message exists.

And the SOE station 100 continues to collect COS in file 2 (F2) when "Information XR" is transmitted. As such, the SOE station 100 stores the COS by rotating the files 1 (F1) to 4 (F4). "Information XR" includes data information currently input to the DIM boards, the collection start time of the file, and the number of data whose status has changed (COS Count).

Although FIG. 2 shows a case in which there are four (F1, F2, F3, F4) SOE data files, the present invention is not limited thereto, and the number of SOE data files may be larger or smaller.

The host server 200, as a master module, synchronizes the corresponding files stored in the SOE station 100, and acquires the SOE data file at regular intervals. At this time, the host server 200 analyzes the "Information XR" transmitted from the SOE station 100, checks the SOE data file that has not yet been acquired, and acquires it using a data request signal (COS Event Dump Request). The host server 200 may store the acquired SOE data file as daily SOE data, and at the same time transmit the COS pointer to the printer 300 and the MMI 400 for output.

As shown in FIG. 2 , the host server 200 includes a communication module 210 , an SOE server 220 , and a database 230 . In addition, the host server 200 may externally include an SOE display unit 240 having an HMI screen for command-based monitoring.

The communication module 210 acquires the SOE data file by synchronizing the SOE data file generated by the SOE station 100 using a dedicated protocol.

In this case, the dedicated protocol used between the SOE station 100 and the communication module 210 includes “Information XR”, “SOE Dump”, “Initial Dump”, “RAS XR”, and “Time Sync.”. "Information XR" synchronizes the data currently input to the DIM boards, the collection start time of the files, and the XR transmission of the status of the conversion data number (COS Count), and "SOE Dump" shows the status of the conversion file (COS event) Synchronized with the data dump (Dump), "Initial Dump" is synchronized with the input data dump of the DIM board when the host server 200 is initialized. In addition, "RAS XR" synchronizes the number of transmitted data (Live Count) and DIM board status information transmission, and "Time Sync." synchronizes the current time write in the host server 200 .

The SOE server 220 reads the SOE data file acquired from the communication module 210 and stores the read SOE data file as daily SOE data in the database 230 . Daily SOE data stored in the database 230 may be provided to an operator through a Man-Machine Interface (MMI) 400 . In addition, when the host server 200 is a duplication action, the SOE server 220 may transmit and output daily SOE data to the printer 300 .

The operator may search the SOE data stored in the host server 200 from a remote location through a Man-Machine Interface (MMI) 400 of a client PC or the like. Through the MMI 400, the operator can analyze the cause of the event and predict the future situation.

3 is a configuration diagram showing the configuration of the communication module in FIG. 2 in detail.

As shown in FIG. 3 , the communication module 210 synchronizes the SOE data file received from the SOE station 100 with the transmitting unit 212 and the receiving unit 211 responsible for transmitting and receiving data in the control network, and provides a data request signal. and an SOE processing unit 214 for recovering SOE data loss by checking a response data signal (SOE Dump Response) according to (COS Event Dump Request). In addition, the communication module 210 includes a message queue 213 that stores and delivers data for data processing between the transmission unit 212 and the reception unit 211 and the SOE processing unit 214 , and the processing contents of the communication module 210 . and a debug processing unit 215 that provides the result to the SOE display unit 240 of the host server 200 for the operator to monitor.

Meanwhile, a transport layer protocol used for communication between the SOE station 100 and the communication module 210 may use User Datagram Protocol (UDP).

The receiving unit 211 receives the SOE related message transmitted from the SOE station 100 and transmits it to the SOE processing unit 214 . The SOE-related message includes data for synchronization between the host server 200 and the SOE station 100 and a response data signal (SOE Dump Response) according to a data request signal (COS Event Dump Request). At this time, the data for synchronization includes "Information XR", "SOE Dump", "Initial Dump", "RAS XR", and "Time Sync.". In addition, the data request signal (COS Event Dump Request) is a signal for requesting SOE data whose state has changed.

The SOE processing unit 214 generates a data request signal (COS Event Dump Request) for the changed SOE data when it is “Information XR” for notifying that there is an SOE data file to be transmitted among the SOE-related messages transmitted from the receiving unit 211 . and transmits it to the transmitter 212 . In this case, the generated data request signal (COS Event Dump Request) may include a sequence number of the changed SOE data.

The transmitter 212 transmits a data request signal (COS Event Dump Request) transmitted from the SOE processor 214 to the SOE station 100 . The SOE station 100 transmits a response data signal (SOE Dump Response) including SOE data corresponding to the data request signal (COS Event Dump Request) to the receiver 211 .

The SOE processing unit 214 parses the response data signal (SOE Dump Response) when it is a response data signal (SOE Dump Response) among the SOE-related messages transmitted from the receiving unit 211 and sends the SOE data to the SOE server 200 . to convey In addition, the SOE processing unit 214 generates a data request signal (COS Event Dump Request) for the next file and transmits it to the transmission unit 212 .

The transmitter 212 transmits a data request signal (COS Event Dump Request) including a sequence number of the next changed SOE data transmitted from the SOE processing unit 214 to the SOE station 100 .

In this case, the transmitter 212 and the receiver 211 and the SOE processor 214 operate as threads, and a message queue 213 may be used to communicate with each other.

The message queue 213 sequentially receives the SOE-related messages input from the receiving unit 211 and delivers them to the SOE processing unit 214 in the order in which they are received, the first message queue 213a, and the SOE processing unit 214 ) and a second message queue 213b that sequentially receives a data request signal (COS Event Dump Request) and transmits it to the SOE station 100 through the transmitter 212 in the order in which they are input.

The debug processing unit 215 provides the processing contents and results of the communication module 210 to the SOE display unit 240 of the host server 200 for the operator to monitor.

FIG. 4 is a configuration diagram showing the configuration of the SOE processing unit in FIG. 3 in detail.

As shown in FIG. 4 , the SOE processing unit 214 includes a file classification unit 10 , a comparison unit 20 , a request signal generation unit 30 , a file information database (DB) 40 , and a timer setting unit 50 . ) and a parsing unit 60 .

The file classification unit 10 checks the SOE-related message transmitted from the receiving unit 211 through a message queue 213 . In addition, the file classification unit 10 determines whether the checked SOE-related message is "Information XR" for notifying that there is an SOE data file to be transmitted, or a response data signal corresponding to a data request signal (COS Event Dump Request) (SOE Dump Response). ) are classified.

When the SOE-related message is "Information XR", the COS is stored in file 1 (F1) in the SOE station 100 as much as a preset size, and the SOE data file to be acquired from the host server 200 is transferred to the SOE station 100. indicates that it exists. In addition, when the SOE-related message is the response data signal (SOE Dump Response), it indicates that the requested SOE data file is transmitted in response to the data request signal (COS Event Dump Request).

When the SOE-related message is classified as “Information XR” in the file classification unit 10 , the comparison unit 20 searches the file information DB 40 to find the currently delivered packet and the file stored in the file information DB 40 . The first saved time (COS Dump Start Time) and the number of data stored in the file (COS Data Number) are compared with each other to determine whether the SOE data file has been changed.

As a result of the comparison of the comparison unit 20 , the request signal generating unit 30 determines that any one of “COS Dump Start Time” and “COS Data Number” of the currently delivered file is different from the value retrieved from the file information DB 40 . That is, when the SOE data file is changed, a data request signal (COS Event Dump Request) is generated using the transmitted information and transmitted to the SOE station 100 through the transmitter 212 .

The timer setting unit 50 monitors the transmitting unit 212 and the receiving unit 211, and whether a response data signal (SOE Dump Response) according to the data request signal (COS Event Dump Request) transmitted to the SOE station 100 is received. check To this end, the timer setting unit 50 sets a timer in the transmitted data request signal (COS Event Dump Request), and the corresponding response data signal (SOE Dump Response) from the time the data request signal (COS Event Dump Request) is transmitted. Count the time until it is received. In this case, when the response data signal (SOE Dump Response) does not respond for a preset period of time (RTO), the timer setting unit 50 determines a packet in which a Retransmission Time Out (RTO) occurs as a transmission error.

When it is determined as a transmission error, the timer setting unit 50 retransmits the previously transmitted data request signal (COS Event Dump Request) to the SOE station 100 . At this time, the timer setting unit 50 initializes the timer set in the request signal (COS Event Dump Request) and resets the timer in the transmitted data request signal (COS Event Dump Request).

The timer setting unit 50 repeats this process until a response data signal (SOE Dump Response) according to the data request signal (COS Event Dump Request) transmitted to the SOE station 100 is received, thereby SOE data file loss to restore In addition, the timer setting unit 50 releases the timer set in the data request signal (COS Event Dump Request) when the response data signal (SOE Dump Response) is received.

Through this process, the communication module 214 synchronizes files 1 to 4 (F1 to F4) generated by the SOE station 100 , and omits the SOE data collected from the SOE station 100 to the SOE server 200 . can be delivered without

On the other hand, when the file classifying unit 10 classifies the SOE-related message as a response data signal (SOE Dump Response), the parsing unit 60 parses the currently transmitted response data signal (SOE Dump Response) to SOE The SOE data is transmitted to the server 200 . Then, the request signal generating unit 30 generates a data request signal (COS Event Dump Request) for the next file and transmits it to the transmitting unit 212 .

As such, the present invention collects and records events occurring in the monitoring and control system in the SOE station 100 in millisecond units, and SOE data acquired when the SOE data file is acquired from the communication module 210 The loss of files can be prevented, so that when an accident occurs in the monitoring and control system, the cause of the accident can be analyzed more accurately and quickly.

5 is a flowchart for explaining the operation of the master communication module for SOE linkage according to an embodiment of the present invention. In this case, the same reference numerals as in FIGS. 1 to 4 refer to the same members performing the same functions.

5, first, the SOE station 100 collects main digital data (event data) that affects system control at high speed and collects SOE data including the occurrence time and sequence of the event data in milliseconds (milliseconds). ) unit and save it as a file. 5 shows a case in which there are four (F1, F2, F3, F4) SOE data files.

The SOE station 100 sequentially stores COS (Change of Status) from file 1 (F1) and when a predetermined time (eg, 10 seconds) elapses or a predetermined number (eg, 1000 COS) is input, It transmits “Information XR (Extended Reports)” to the communication module 210 . And the SOE station 100 continues to collect COS in file 2 (F2) when “Information XR” is transmitted. As such, the SOE station 100 stores the COS by rotating the files 1 (F1) to 4 (F4). "Information XR" includes data information currently input to the DIM boards, the collection start time of the file, and the number of data whose status has changed (COS Count).

And when "Information XR" for notifying that the SOE data file F1 to be transmitted exists through the receiving unit 211 is received, the communication module 210 receives a first data request signal (COS Event Dump Request # for the changed SOE data) 1) is created. In addition, the communication module 210 transmits the first data request signal (COS Event Dump Request #1) including the sequence numbers (SOE Data #0 to 99) of the SOE data changed through the transmitter 212 to the SOE station 100 . transmit

At this time, the communication module 210 sets a timer to the first data request signal (COS Event Dump Request #1) transmitted through the timer setting unit 50 of the SOE processing unit 214, and the first data request signal (COS) The time from transmission of the Event Dump Request #1) to the reception of the corresponding first response data signal (SOE Dump Response #1) is counted.

Subsequently, the SOE station 100 transmits a first response data signal (SOE Dump Response #1) including SOE data stored in file 1 (F1) corresponding to the transmitted first data request signal (COS Event Dump Request #1). is generated and transmitted to the communication module 210 .

When the communication module 210 receives the first response data signal (SOE Dump Response #1) from the SOE station 100, the communication module 210 parses the first response data signal (SOE Dump Response #1) to the SOE server 200 ), and release the timer set in the first data request signal (COS Event Dump Request #1).

And the communication module 210 generates a second data request signal (COS Event Dump Request) for the next file, file 2 (F2). In addition, the communication module 210 transmits the second data request signal (COS Event Dump Request #2) including the changed sequence numbers (SOE Data #100 to 199) of the SOE data to the SOE station 100 . At this time, the communication module 210 sets a timer to the second data request signal (COS Event Dump Request #2) transmitted through the timer setting unit 50 of the SOE processing unit 214, and the second data request signal (COS) A time is counted from the time the Event Dump Request #2) is transmitted until the corresponding second response data signal (SOE Dump Response #2) is received.

Subsequently, the SOE station 100 transmits a second response data signal (SOE Dump Response #2) including SOE data stored in file 2 (F2) corresponding to the transmitted second data request signal (COS Event Dump Request #2). is generated and transmitted to the communication module 210 .

At this time, when the second response data signal (SOE Dump Response #2) is damaged or lost (Pkt.Lost) on the control network, which is a wired network, while being transmitted to the communication module 210, the communication module 210 The second response data signal (SOE Dump Response #2) corresponding to the second data request signal (COS Event Dump Request #1) cannot be received.

Accordingly, when there is no response (RTO) for the second response data signal (SOE Dump Response #2) for a preset time, the communication module 210 determines that a packet in which a retransmission time out (RTO) occurs is a transmission error. If it is determined that the transmission error is transmitted, the communication module 210 retransmits the previously transmitted second data request signal (COS Event Dump Request #2) to the SOE station 100 . At this time, the timer set in the communication module 210 request signal (COS Event Dump Request) is initialized and the timer is reset in the transmitted second data request signal (COS Event Dump Request #2).

The SOE station 100 transmits a second response data signal (SOE Dump Response #2) including SOE data stored in file 2 (F2) corresponding to the retransmitted second data request signal (COS Event Dump Request #2). It is retransmitted to the communication module 210 .

When the second response data signal (SOE Dump Response #2) is received from the SOE station 100 , the communication module 210 parses the second response data signal (SOE Dump Response #2) to the SOE server 200 . ), and release the timer set in the second data request signal (COS Event Dump Request #2).

And the communication module 210 generates a third data request signal (COS Event Dump Request #3) for the next file, file 3 (F3). In addition, the communication module 210 transmits the third data request signal (COS Event Dump Request #3) including the changed sequence numbers (SOE Data #200 to 299) of the SOE data to the SOE station 100 . At this time, the communication module 210 sets a timer in the third data request signal (COS Event Dump Request #3) transmitted through the timer setting unit 50 of the SOE processing unit 214, and the third data request signal (COS) The time is counted from the time the Event Dump Request #3) is transmitted until the corresponding third response data signal (SOE Dump Response #3) is received.

Through this process, the communication module 214 synchronizes files 1 to 4 (F1 to F4) generated by the SOE station 100 , and omits the SOE data collected from the SOE station 100 to the SOE server 200 . can be delivered without
