Description

  The present invention relates to a plant state analysis system and a plant state analysis method for integrating and managing plant information and work performance information in a plant facility.

  In order to manage plant facilities, a plant monitoring device and a work management system are usually provided. The plant monitoring device aggregates all plant data such as plant operation information, alarm history, and plant parameters (analog information), displays the status of the entire plant to the operator, and supports operation operations. Do. In addition, data for displaying the operation status of each facility is stored for a certain period of time. When an operation log is automatically created or an accident or malfunction occurs, analysis is performed based on this history data. In addition, the work management system centrally manages plant facility information and inspection data in order to efficiently perform facility maintenance work.

  Each equipment information of the plant monitoring device does not necessarily have an accurate equipment name, especially when the equipment name is very long, the number of displayed characters is limited so that the operation information can be understood early. . Therefore, it is common to display using specialized abbreviations and often does not completely match the facility information of the work management system.

  As a technology related to these, Patent Document 1 discloses equipment information management in which device names are linked between a plant monitoring control system and a facility information management system, and information on the plant operation status is acquired from the plant monitoring control system. A system configuration is disclosed. Patent Document 2 discloses a configuration of a plant state monitoring system in which operation control information, field information, and facility maintenance technical information are connected via a network and integrated and managed.

  In the work management system, the maintenance work plan is basically performed in the room of the maintenance department, so that the maintenance department office network (usually an in-house LAN or the like) is used. When such a work management system is connected to a plant monitoring apparatus and managed, a security problem with the outside arises. Therefore, in a highly confidential plant facility, the plant monitoring device and the work management system are conventionally configured independently.

  On the other hand, when performing maintenance work of plant equipment, power may not be supplied to the plant monitoring device due to work such as shutting off the power supply of the equipment, and plant information may not be collected during that period. As a result, when the plant monitoring device and the work management system are configured independently, it is difficult to accurately grasp the state of the plant equipment during the maintenance work period in the central control room that collectively displays the plant information. .

  In patent document 1, when the signal path | route to plant equipment is interrupted | blocked by maintenance work, the case where plant information cannot be collected from a plant monitoring apparatus is not considered. In patent document 2, the security problem at the time of connecting a plant monitoring apparatus and a work management system on a network is not considered.

  Further, as a problem other than the above, even if the plant information and the work management information are collectively managed, for example, it is difficult to analyze the plant state when an accident occurs in the facility. Plant information is analyzed by using already-acquired plant information using the operation determination logic of each device, but the plant information becomes a large amount of data in a short period of time, and the number of devices in the plant is enormous. Therefore, it is not easy for an operator to perform analysis work, and it is difficult to quickly obtain an analysis result of plant information.

  Accordingly, an object of the present invention is to provide a plant state analysis system and a plant state analysis method that have an analysis function in case of emergency while ensuring security, and that quickly complements even when plant information is lost. .

  The present invention operates a plant monitoring device that monitors the operating state of a plant facility, a work management system that manages plant facility maintenance work, a plant state analyzing device that analyzes an operating state of the plant facility, and a plant state analyzing device. A plant state analysis system including an operation terminal for performing operation, wherein the plant state analysis device includes plant information transmitted from the plant monitoring device, data storage for storing work performance information transmitted from the work management system, and an operation terminal. In response to the request, the search processing unit that searches for predetermined information from the data storage using the search library, and if the searched information has a missing part, the missing part is analyzed using the analysis pattern library to supplement the information An analysis processing unit, and display search results and analysis results by the plant state analyzer on the operation terminal. Configuration to. Here, the plant monitoring device and the work management system are connected to the plant state analysis device via a firewall.

  According to the present invention, an emergency analysis function is provided while ensuring security, and even when plant information is lost, this can be quickly complemented, so that the plant state analysis function is improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an overall configuration diagram showing an embodiment of a plant state analysis system according to the present invention. The plant state analysis system 101 connects a plant monitoring device 102 and a work management system 103 to a plant state analysis device 105 via a firewall 104, and the plant state analysis device 105 has an operation terminal via a hub (HUB) 113. 114 is connected.

  The plant monitoring device 102 monitors plant facilities, collects analog signals of equipment and piping constituting the plant, digital signals such as equipment operation signals and alarm states, and assigns the collected date and time data to the firewall 104. Is transmitted to the plant state analyzer 105 at a constant cycle. Hereinafter, information sent from the plant monitoring apparatus 102 is referred to as “plant information”.

  The work management system 103 manages the maintenance work of the plant equipment, and schedules / actual data such as work items, work dates, and isolation states of each equipment related to the maintenance work of plant equipment and piping are scheduled via the firewall 104. It is transmitted to the plant state analysis apparatus 105 at the time of registration and at the time of work performance registration. Hereinafter, information sent from the work management system 103 is referred to as “work result information”.

  As described above, in the present embodiment, the plant monitoring apparatus 102, the work management system 103, and the plant state analysis apparatus 105 are connected via the firewall 104. Therefore, even if a third party enters the work management system 103 from an external network, the data and programs handled by the plant monitoring apparatus 102 and the plant state analysis apparatus 105 can be protected and the security of the system can be ensured.

  The plant state analysis device 105 receives and accumulates data transmitted from the plant monitoring device 102 and the work management system 103, searches the accumulated data in response to a request, and analyzes if the plant information is missing. The function which complements is provided. Received data collected from the plant monitoring apparatus 102 and the work management system 103 is temporarily transferred to the input / output memory 106 and then stored in the data storage 107.

  Upon receiving a device operation or parameter display request for a certain period from the operation terminal 114, the search processing unit 108 searches the data storage 107 for plant information, device operation information, and work performance information at the target time. The search operation is efficiently performed using a search library 109 for selecting search items. In addition, when there is a defect in the information searched by the search processing unit 108, the analysis processing unit 110 analyzes the device operation and parameters of the missing part. The analysis work is efficiently performed using the analysis pattern library 111 describing the operation determination logic of each device. The operation input / output unit 112 transmits the search / analysis result to the operation terminal 114 via the HUB 113. The operation terminal 114 uses a GUI (Graphical User Interface) screen to input search requests and display analysis results.

  FIG. 2 is a diagram illustrating a hardware configuration of the plant state analysis apparatus 105. The plant state analysis apparatus 105 is configured by, for example, a microcomputer, and a CPU 201, a ROM 202, a RAM 203, and a nonvolatile storage 204 are connected via a bus 205. Further, an input / output memory 106 connected to the firewall 104 and a NIC (Network Interface Card) 206 connected to the HUB 113 are connected to the bus 205.

  The CPU 201 controls the input / output of data in the plant state analysis apparatus 105 and executes the functions of the search processing unit 108 and the analysis processing unit 110 in FIG. The non-volatile storage 204 is composed of, for example, a hard disk device, has the function of the data storage 107 in FIG. 1, stores a search library 109 and an analysis pattern library 111, and further stores a program used by the CPU 201.

  FIG. 3 is a diagram illustrating a processing flow of each block in the plant state analysis system 101. The data storage 107 stores plant information and work performance information received from the plant monitoring apparatus 102 and the work management system 103. Hereinafter, the flow of retrieval and analysis processing of stored information will be described.

  The operator operates the operation terminal 114 to input a search target start time and end time, and transmits them to the plant state analysis apparatus 105 (S301). When the operation input / output unit 112 receives the target time (S302), it passes it to the search processing unit 108 and sets the search target time (S303). Subsequently, the operator selects information (search item) to be searched from the operation terminal 114, and transmits it to the plant state analysis apparatus 105 (S304). When the operation input / output unit 112 receives information to be searched (S305), the operation input / output unit 112 requests the search processing unit 108 to search for data (S306).

  The search processing unit 108 searches the data storage 107 using the search library 109 for the search target time range set in S303 and the data search item requested in S306 (S307). If there is a missing portion in the retrieved data, the analysis processing unit 110 determines accompanying data necessary for the analysis of the missing portion using the analysis pattern library 111 (S308), and the search processing unit 108 searches for the accompanying data. Is requested (S309).

  The search processing unit 108 searches for the requested accompanying data from the data storage 107 using the search library 109 (S310), and sends the searched accompanying data to the analysis processing unit 110 (S311). The analysis processing unit 110 performs data analysis of the missing portion according to the analysis pattern library 111 using the received accompanying data (S312). When the analysis processing unit 110 completes the analysis, the analysis result is transmitted to the operation terminal 114 via the operation input / output unit 112 (S313), and the operation terminal 114 displays the search target information (S314).

  FIG. 4 is a diagram showing a processing flow of data analysis performed by the plant state analysis apparatus 105, and describes the processing flow of FIG. 3 in time series. First, a search library 109 and an analysis pattern library 111 for performing search processing and analysis processing are pre-registered in the plant state analysis device 105 (S401), and plant information and work results are received from the plant monitoring device 102 and the work management system 103. Information is collected and stored in the data storage 107 (S402). Thereafter, data collection and storage will continue.

  The operator inputs a start time and an end time as a search target period from the operation terminal 114 (S403), and selects a search target item from a selection screen displayed using the search library 109 (S404). The search processing unit 108 searches for the requested data from the data storage 107 using the search library 109 (S405).

  The analysis processing unit 110 determines whether there is a missing portion in the retrieved data (S406). Specifically, it is determined whether or not there is a period in which the data value is indefinite in the retrieved plant information. If there is no missing portion, the process proceeds to S410. If there is a missing part, the analysis processing unit 110 refers to the analysis pattern library 111 to determine accompanying data necessary for the analysis of the missing part, and obtains it from the data storage 107 via the search processing part 108 (S407). .

  The analysis processing unit 110 performs data analysis of the missing portion using the acquired accompanying data (S408). The contents include (1) setting the analysis target time when the defect occurs, (2) analyzing using the analysis pattern (determination logic circuit) and accompanying data, and (3) complementing the data of the defect part. Data analysis is performed for a plurality of times at predetermined intervals, and is repeated until the entire period of the missing portion is completed (S409).

  When the analysis is completed, the operator selects a display format from the operation terminal 114 (S410), and displays the search / analysis result on the screen of the operation terminal 114 (S411). The analysis results are saved or discarded as necessary.

  Next, the data structure stored in the data storage 107, the search library 109, and the analysis pattern library 111, and the data search method and data analysis method using the data structure will be described.

5 to 6 show examples of plant information and work performance information stored in the data storage 107.
FIG. 5 is a diagram illustrating an example of plant information received from the plant monitoring apparatus 102 and stored in the data storage 107. Plant information is classified into analog data and digital data.

  (A) is the case of analog data, which corresponds to process values such as pressure, flow rate, and temperature. As shown in the table 501, the storage format is classified using a system number representing a plant system, a type code A representing analog data, and a consistent number. Then, the collected date / time data is assigned and the process values are stored in time series.

  (B) is the case of digital data, which is information representing the start / stop state of the pump, the open / close state of the valve, and the presence / absence of an alarm in binary. For example, the open / closed state of the valve is expressed by a combination of an open signal and a close signal, and means an open state when the open signal is ON and a close signal OFF, and a closed state when the open signal is OFF and the close signal is ON. Further, the open signal ON and the close signal ON mean an intermediate open state, and the open signal OFF and the close signal OFF mean an indefinite state. As shown in the table 502, the storage format is classified by a system number representing a plant system, a type code B representing digital data, and a consistent number. Then, the collected date and time data is added and the digital information is stored in time series.

  In the tables 501 and 502, by classifying using the system number and the consistent number, it is possible to uniquely search for desired data from the search processing unit 108 or the search library 109. The tables 501 and 502 have an area where all signals can be stored for a certain period. Since this storage area is limited, the latest data is overwritten cyclically on the past data.

  FIG. 6 is a diagram illustrating an example of work result information received from the work management system 103 and stored in the data storage 107. (A) shows a work list, and (b) shows detailed information about each work.

  (A) is a work list of work performance information. As shown in the table 601, the save format is assigned a work number uniquely identifying one work, and a system number indicating the system of the plant and the type of equipment. Stores equipment information that can uniquely identify equipment in the plant by the equipment code and the consistent number, and the work start date and work end date. (B) is detailed information for one work number. As shown in the table 602, the storage format stores the detailed procedure of the work, its start time and end time, and information on the work status (device stop) for the device. .

  In the tables 601 and 602, desired data can be uniquely searched from the search processing unit 108 and the search library 109 by classifying them according to work numbers and device information (system number, device code, consistent number).

  7 to 10 show examples of various search patterns (search item tables) stored in the search library 109. FIG. The search library 109 stores tens of thousands of search pattern records for searching plant information, work performance information, and plant facility design drawings, but only a part thereof is disclosed here.

  FIG. 7 is a diagram showing a search pattern for plant information (analog data). The table 701 in the search library 109 describes the plant system number and system name as search items, and the table 702 has a consistent number, signal name, instrument type, instrument number, measurement range lower limit, and measurement for each system. The upper limit of the range and the engineering unit of the measurement range are described. The system numbers and the consistent numbers used in the tables 701 and 702 are the same as the numbers and symbols used in the plant information table 501 in FIG.

  In the search operation, search pattern tables 701 and 702 are displayed in a pull-down display on the search screen of the operation terminal 114, and the operator selects and narrows down items to be searched. A table 703 shows a selection example, and the pointer “704” selects the system “XX” and the pointer 705 selects the consistent number “A001”. As a result, the search target is uniquely determined, and the related information of the search target is displayed in a list on one line as shown on the screen 706. The table 703 ′ shows another selection example. After selecting the system “XX” with the pointer 704, the instrument type “FT (flow rate)” is selected with the pointer 707, and the instrument number “001” is selected with the pointer 708. Also in this case, the search target is uniquely determined, and the related information of the search target is displayed as a list in one line as shown on the screen 706.

  If the search information cannot be narrowed down uniquely by the selected item alone, a so-called fuzzy search can be performed in which a plurality of related search targets are displayed in a list on a plurality of lines as shown in the screen 709, and the desired target is narrowed down. It is.

  FIG. 8 is a diagram showing a search pattern for plant information (digital data). A table 801 in the search library 109 describes a plant system number and a system name as search items, and a table 802 includes a consistent number, a signal name, a device type, a device number, and an ON state display character for each system. Column, and the display character string in the OFF state are described. The system number and the consistent number used in the tables 801 and 802 are the same as the numbers and symbols used in the plant information table 502 shown in FIG.

  In the search operation, search pattern tables 801 and 802 are displayed in a pull-down display on the search screen of the operation terminal 114, and the operator selects and narrows down items to be searched. A table 803 shows a selection example, and the system “XX” is selected by the pointer 804 and the consistent number “B001” is selected by the pointer 805. As a result, the search target is uniquely determined, and the related information of the search target is displayed in a list on one line as in the screen 806. The table 803 ′ shows another selection example. After selecting the system “XX” with the pointer 804, the device type “PUMP” is selected with the pointer 807, and the device number “001” is selected with the pointer 808. In this operation example, the search target is not uniquely determined, and a plurality of (two types) of related search targets are displayed in a list on a plurality of lines as in the screen 809, and a desired target can be narrowed down from this.

  FIG. 9 is a diagram showing a search pattern for work performance information. A table 901 in the search library 109 describes a plant system number and a system name as search items, and a table 902 includes a device / instrument type, device / instrument number, device / instrument name, state 1 for each system. , State 2, unit, and installation location are described. The numbers used in the tables 901 and 902 are the same as the numbers and symbols used in the work performance information tables 601 and 602 shown in FIG.

  In the search operation, search pattern tables 901 and 902 are displayed in a pull-down display on the search screen of the operation terminal 114, and the operator selects and narrows down items to be searched. A table 903 shows an example of selection. The pointer “904” selects the system “XX”, the pointer 905 selects the device / instrument type “PUMP”, and the pointer 906 selects the device / instrument number “001”. In this case, the search target is uniquely determined, and the related information of the search target is displayed as a list on one line as shown on a screen 907.

  In addition, when the search information cannot be narrowed down uniquely by the selected item alone, a so-called fuzzy search is possible in which a plurality of related search targets are displayed in a list on a plurality of lines as in the screen 908, and the desired target is narrowed down from now on. It is.

  FIG. 10 is a diagram showing various design drawings of plant equipment stored in the search library 109. A table 1001 describes a system number and a system name of a plant as search items, and a table 1002 describes a drawing name and a drawing number related to each system. Further, design drawing data 1003 corresponding to the drawing number described in the table 1002 is stored. The drawing data stored here includes equipment information and instrument information such as a piping instrumentation diagram (hereinafter referred to as P & ID), and shows a procedure for obtaining drawing data to be searched from P & ID as an example.

  In the search operation, design drawing tables 1001 and 1002 are displayed in a pull-down display on the search screen of the operation terminal 114, and the operator selects a search target. A table 1004 shows an example of selection, and a system “XX” is selected with a pointer 1005 and a drawing name “pipe instrumentation diagram” is selected with a pointer 1006. As a result, the search target is uniquely determined, and the search target P & ID is searched from the plurality of drawing data 1003 and displayed on the operation terminal 114 as shown on the screen 1007.

  Furthermore, by selecting the device / instrument “XX-PUMP-001” displayed on the drawing 1007 with the pointer 1008, the device / instrument to be searched is designated, and the plant information and the information described in FIGS. It is also possible to automatically search for work performance information. If a drawing to be searched cannot be uniquely determined, a plurality of related search targets can be displayed as a list as shown in a screen 1009 and a fuzzy search can be performed from now on.

11 and 12 show an example of data analysis and an example of the analysis pattern library 111. FIG.
FIG. 11 is a diagram showing a data analysis example, and a case where a missing portion of plant information generated by the inspection work of the pump A is analyzed will be described. (A) is work performance information of the pump A collected from the work management system 103. (B) is the operating state of the pump A determined only by the plant information collected from the plant monitoring apparatus 102. (C) is the operating state of the pump A determined by the plant state analyzing apparatus 105 of the present embodiment.

  As shown in the work performance information of (a), the pump is inspected for a period of t2 to t5. The breakdown of the work is that the pump A was stopped during the period from t2 to t3, the pump A was started during the period from t3 to t4 for confirmation after inspection, and was stopped again during this period from t4 to t5. . Further, the signal input device of the pump A was stopped during the period from t1 to t6 due to the modification work.

  (B) is an operation status determination result of the pump A based only on plant information. In the stop periods t1 to t6 of the signal input / output device of the pump A, both the start signal and the stop signal of the pump A are detected as “0”. When this is referred to the operation status determination logic of the pump A, the period from t1 to t6 is determined to be “indefinite” and the operation status cannot be determined. That is, the period from t1 to t6 is a missing period of plant information.

  (C) is the result of analyzing the missing periods t1 to t6 of the plant information. For the analysis, the work record information shown in (a) is used for the missing periods t1 to t6 of the plant information. Hereinafter, the operating status of the pump A is determined as follows.

  From the work record information of (a), it can be seen that the pump A was stopped at the time t2. Further, since the plant information remains indefinite at the time t2, it is determined that the pump A is stopped at the time t2. During the period from t2 to t3, since there is no change in the work record information and the plant information, it is determined that the stopped state continues. It is determined that the pump A is activated at the time t3 because the pump A is activated in the work performance information at the time t3, and there is no change in the plant information. During the period from t3 to t4, since there is no change in the work record information and the plant information, it is determined that the activated state is continued. Since the pump A is stopped in the work record information at the time t4 and the plant information is not changed, it is determined that the pump A is stopped at the time t4. During the period from t4 to t5, since there is no change in the work record information and the plant information, it is determined that the stopped state continues. Since the pump A is activated in the work performance information at the time t5 and the plant information is not changed, it is determined that the pump A is activated at the time t5. Since there is no change in work performance information and plant information during the period from t5 to t6, it is determined that the activated state continues. Since the plant information is normally input at time t6, the determination is switched to the determination based on the plant information.

  FIG. 12 is a diagram showing an example of the analysis pattern library 111. Here, analysis patterns used in the analysis example described in FIG. 11 are shown. The table 1201 in the analysis pattern library 111 describes an analysis pattern number (No) 1202 and a list of input items 1203 used for operation analysis for each device / instrument number. On the other hand, the analysis pattern library 111 stores a plurality of analysis patterns 1204 for each device / instrument number, and the pattern number 1206 of each analysis pattern 1204 is associated with the pattern number 1202 of the table 1201.

  The analysis pattern 1204 is composed of, for example, a logic circuit, and the input unit 1205 of the logic circuit corresponds to the input item 1203 of the table 1201. When the device state at the analysis target time is input to the input unit 1205, the operation state of the device at the target time is calculated by a logic circuit and output. This calculation corresponds to the determination method described in FIG. 11C, and the same determination result as in FIG. 11C can be obtained by repeatedly executing the analysis at each time of the missing periods t1 to t6. . Note that the analysis pattern 1204 is not necessarily configured by a logic circuit, and may be any pattern that can correspond to the input item 1203 of the table 1201.

  In the plant information and device information, for example, the operation state of the device and the open / close state of the valve are defined by a combination of two digital signals. For example, when the valve is changed from the closed state to the open state, the determination signal is complicated because the valve open signal changes from OFF to ON and the close signal changes from OFF to ON. In addition, since the number of devices included in the plant is enormous, it is not easy for the operator to analyze based on the design drawing when the plant information is missing, and much time is spent. On the other hand, in the present embodiment, the analysis pattern for each device is stored in the analysis pattern library 111, so that it is possible to automatically analyze the defect information quickly by using this.

  FIG. 13 is a diagram illustrating a display method of search results and analysis results on the operation terminal 114. The operator designates the display period (start time and end time) 1301 from the operation terminal 114 in the format of year / month / day / hour / minute / second. The search processing unit 108 searches for plant information and work performance information for a period specified by the procedure shown in FIGS. 7 to 10 and displays a display list 1302 for selecting the display conditions. The display list 1302 is provided with a check box 1303 for selecting whether or not analysis based on work performance information is necessary for the loss of plant information. In the display method 1304, display formats such as trend display, point display, and list display can be selected. For analog data, the display range (lower limit and upper limit) 1305 can be set (the values in parentheses indicate the lower limit and upper limit of the measurement range).

  Next, display examples of various information will be described. The case where plant information (analog data, digital data) and work performance information (device information, work information) are displayed in the display formats of trend display 1306, point display 1307, and list display 1308 is shown.

  Among the plant information, in the trend display 1306 of analog data, the X axis is the time axis, the Y axis is the analog value, and the Y axis is the designated display range (lower limit value and upper limit value). A trend graph is generated by mapping plant information (analog data) collected from the plant monitoring apparatus 102 to this. In the point display 1307, the X axis is set as the time axis, and the position of the cursor is set to the desired position on the time axis, thereby displaying the analog data value at that time. In the list display 1308, the analog data value at each time is displayed in a table format.

  When displaying other information, it is almost the same as the display format of analog data. In the case of digital data in the plant information or equipment information in the work performance information, the data to be displayed is either “startup” or “stop”. In the case of work information among work performance information, data to be displayed are “preparation”, “disassembly”, “replacement”, and “assembly” which are detailed items of maintenance inspection work.
