Description

  Embodiments described herein relate generally to an information processing system.

  In general, in a power plant or industrial plant, a plant supervisory control system composed of dedicated components specialized for stable plant operation is employed for plant operation and supervisory control.

  The plant supervisory control system needs to perform control safely based on a control program based on information from devices and sensors to be monitored and controlled. Therefore, even today, many of the components that make up the plant monitoring and control system are often made up of specially designed components.

  For this reason, in the plant monitoring and control system, connection with other general networks has not always been flexible. For this reason, the engineering of the plant supervisory control system required considerations different from those of general systems.

  For example, when creating or changing a control program, the control program for the controller is stored in a dedicated area of the controller (for example, ROM, EP-ROM, etc.). Even in the work, in order to perform such engineering, it was necessary to use a dedicated engineering device.

  However, in recent years, the progress of global networking has been remarkable, and the plant monitoring and control system itself has a configuration utilizing the advantages of network technology. For example, there is a distributed plant monitoring and control system (DCS: Distributed Control System) in which monitoring operation devices and controllers are distributedly arranged for the purpose of monitoring plant operation status and saving labor in plant operations, and each is connected by network technology. Appeared.

  However, the above-described network is a dedicated network, for example, in units of power generation units in a plant or a plant including a plurality of power generation units such as a power plant, and is physically or logically disconnected from other networks. It was.

  Typically, engineers are not in the user's plant where the plant monitoring and control system is installed. Therefore, even if the engineer himself needs engineering work to examine the controllability of the control program by collecting and displaying the control program that is actually operating and the data during the calculation, it still remains A desk study is underway. Alternatively, a configuration conforming to the plant monitoring control system is installed at an engineer's site, and engineering work is performed.

  In order to reflect the results on the plant monitoring and control system that is actually installed, the engineer gives instructions to the site engineer via books, media, Internet mail, etc., or the engineer himself visits the site and performs the work. There is a need. For this reason, there is a problem that it takes a lot of time and effort from the engineer.

  Accordingly, an aspect of the present invention has been made in view of the above problems, and an object thereof is to provide an information processing system that can reduce the labor of an engineer when performing engineering work related to a plant.

  The monitoring server 1 communicates with the plant monitoring control system 2 and the terminal device 3 via the communication network 4. As an example, the monitoring server 1 is installed in a place different from the plant monitoring control systems 2-1, ..., 2-N. The monitoring server 1 has, for example, one or more computers and a storage area. Since these computers and storage areas are not shown because they are not related to the configuration of the present invention, they may be located at a single site or distributed at a plurality of sites. A service provided by the monitoring server 1 can be used by a plurality of users for a plurality of engineering described later.

  In addition, the plant monitoring control system 2 may implement only either monitoring or control of the control target equipment installed in the plant. As described above, the plant monitoring control system 2 may perform at least one of monitoring and control of the control target equipment installed in the plant.

  The plant monitoring control system 2 transmits all data handled by the plant monitoring control system 2 to the monitoring server 1 via the communication circuit network 4 (for example, communication means such as a public line or a global network). Moreover, the plant monitoring control system 2 receives the data transmitted from the monitoring server 1 as needed.

  The terminal device 3 communicates with the plant monitoring control system 2 via the communication network 4. The terminal device 3 displays information received from the plant monitoring control system 2. The terminal device 3 is a personal computer, for example.

  The monitoring server 1 and the plant monitoring control systems 2-1, ..., 2-N may communicate with each other by wire or wirelessly. Moreover, the plant monitoring control systems 2-1, ..., 2-N and the terminal device 3 may communicate with each other by wire or wirelessly.

FIG. 2 is a schematic block diagram showing the configuration of the plant monitoring control system 2 in the embodiment of the present invention.
The plant monitoring control system 2 includes a controller (control unit) 21, a monitoring operation unit (monitoring unit) 22 connected to the controller 21 via the bus 24, and a monitoring control system communication unit connected to the controller 21 via the bus 24. 23 and a bus 24.

The controller 21 takes in information on the control target device (for example, pump, valve, sensor, valve) 5 and controls the control target device 5 installed in the plant by a control program held by the controller 21. Here, the control target device 5 is a plant constituent device constituting the plant.
In addition, the controller 21 monitors the control program of the controller 21 and the plant data indicating the state and control state of the control target device 5 for the purpose of monitoring the operation of the plant, which are created by the calculation thereof, connected via a bus. Output to the operation means 22 and the monitoring control system communication means 23.

The monitoring operation means 22 displays the plant data input from the controller 21 as necessary for plant monitoring and operation. Moreover, the monitoring operation means 22 receives, for example, an operation command to the plant performed by a person who uses the monitoring operation means 22 (for example, a plant operator), and the received operation command to the plant is used as notification data for the controller 21. Delivered to the controller 21.
The monitoring operation means 22 monitors information indicating the current state of the plant, and operates a device to be controlled as necessary. As described above, the monitoring operation unit 22 monitors the control target device.

  The monitoring control system communication unit 23 communicates with the monitoring server 1 via the communication circuit network 4. For example, the monitoring control system communication unit 23 transmits the plant data input from the controller 21 to the monitoring server 1 via the communication circuit network 4. The monitoring control system communication unit 23 transmits monitoring information obtained by monitoring by the monitoring operation unit 22 to the monitoring server 1 via the communication circuit network 4.

  FIG. 3 is a schematic block diagram showing the configuration of the monitoring server 1 in the embodiment of the present invention. The monitoring server 1 includes a monitoring server communication unit (communication unit) 11, a data management unit 12, an engineering unit 13, a device monitoring unit 14, a book management unit 15, and a virtualization unit 16.

  The monitoring server communication means (communication unit) 11 communicates with the plant monitoring control systems 2-1 to 2 -N and the terminal device 3. For example, the monitoring server communication unit 11 receives the monitoring information transmitted by the monitoring control system communication unit 23 via the communication circuit network 4.

  The data management means 12 manages all data handled by the plant monitoring control system 2 and stores all the data. Specifically, the data management means 12 includes, for example, plant information related to the plant, general information (for example, the name and address of the plant), control target device information related to the control target device (plant configuration device), and plant configuration device. The equipment arrangement information regarding the arrangement of the plant, the book management information including the drawings and texts of the plant, the control monitoring information about the constituent equipment of the plant and the control program for controlling the control target equipment are stored.

  The engineering unit 13 performs engineering on the control target device 5 or the devices constituting the plant monitoring control system 2 by communicating with the plant monitoring control system 2 via the monitoring server communication unit 11.

The monitoring server communication unit 11 receives status information indicating the status of at least one of the plant monitoring control system 2 or the control target device from the plant monitoring control system 2.
The device monitoring unit 14 detects a failure or abnormality of at least one of the plant monitoring control system 2 or the control target device based on the status information received by the monitoring server communication unit 11.

  Further, the device monitoring unit 14 reads out the control target device information stored in the data management unit 12, for example, and performs control based on the read control target device information and the monitoring information received by the monitoring server communication unit 11. Information for monitoring the target device is output to the monitoring server communication unit 11. In that case, the monitoring server communication unit 11 transmits the information output by the device monitoring unit 14 to the terminal device 3 that displays this information. Thereby, the terminal device 3 displays information for monitoring the control target device.

  Further, the data management unit 12 may store at least control target device information related to the control target device. In that case, the engineering means 13 changes part or all of the information stored in the data management means 12. Then, the book management unit 15 manages the information after the engineering unit 13 has changed in a predetermined data format.

  The virtualization means 16 realizes a virtual plant in its own apparatus based on information related to the specification of the control target device and information related to the design of the entire plant, and a control program executed by the plant monitoring control system 2 in this virtual plant The operation of the plant is predicted by operating the plant simulator corresponding to this.

  As shown in FIG. 3, the plant monitoring control system 2 does not include the engineering means 13, but the engineering server 13 is provided in an engineering base located at a remote place from the plant or in another base.

(Example 1)
Subsequently, a first embodiment of the information processing system 100 described above will be described.
In general, in order to send and receive data via a communication line that can exchange data with a distant place, along with devices such as routers and modems, intrusion detection devices and firewalls installed as necessary to avoid security risks Together with authentication and encryption communication protocol represented by virtual private network.

  However, the plant monitoring control system 2 is a system that requires a certain real time property. In addition, the delay time of a network such as a public line is not usually constant, and it is not a problem if it is limited only to the monitoring of the devices that make up the plant monitoring control system. In view of the fact that the engineer monitors the control program and the data handled by the control program and displays it at an engineering level, the combination of common communication methods is not sufficient.

  In addition, the cost of authentication and encrypted communication for avoiding a security risk while ensuring the above-described delay time and certain responsiveness cannot be ignored.

  In order to avoid these problems, in the present embodiment, the plant monitoring control system 2 and the monitoring server 1 are each provided with a monitoring control system communication unit 23 and a monitoring server communication unit 11. The communication method used between the monitoring control system communication unit 23 and the monitoring server communication unit 11 is preferably as simple as possible.

  As an example, in this embodiment, a method of using transmission data as a stream is adopted as a simple method. That is, as an example, the monitoring control system communication unit 23 and the monitoring server communication unit 11 convert transmission data into a stream signal and transmit the converted stream signal. The monitoring control system communication unit 23 and the monitoring server communication unit 11 receive the stream signal, decode the received stream signal, and obtain the original transmission data.

  In the stream communication, it is known that a certain amount of data is lost. However, in the plant monitoring and control system, the data itself is a numerical value or an On / Off binary signal and a text base, and is generally remote. Compared to a protocol such as a remote operation method known as desktop, the processing cost for converting these into stream signals is low. Similarly, when decoding, the processing cost is low. For this reason, even if there is data loss in the datagram, the cost for retransmitting only the data is small and sufficient to cover the loss. The cost of encrypting data is also low.

  Note that the monitoring control system communication unit 23 and the monitoring server communication unit 11 may adopt a so-called remote desktop protocol.

  As another example, a method may be considered in which each communication data UTC (Universal Standard Time) is compiled into data of a certain time and synchronized afterwards. For example, the monitoring control system communication unit 23 and the monitoring server communication unit 11 calculate the transmission of the network based on the data frequency to be transmitted based on UTC and the natural frequency held by each communication unit. A datagram of a specific format with time data may be transmitted to the communication network.

  The monitoring server communication unit 11 that has received the datagram does not perform any special processing if the network throughput is within the reference value. However, the monitoring server communication unit 11 may buffer the transmission data according to the degree of deviation from the reference value when it deviates from the reference value, and perform a process of collectively transmitting and receiving data for a certain period.

  It is desirable that the monitoring server communication unit 11 switches the communication target in principle. This is because the monitoring server communication means 11 included in the monitoring server 1 makes it easy to select the plant monitoring control system 2 that easily secures a communication band.

  In addition, the monitoring server communication unit 11 transmits the random number list data for encryption periodically or when a specific condition is satisfied in order to perform classification for each plant and avoid security risk. Here, the random number list data for encryption is list data of random numbers used when data is encrypted.

  For example, it is determined whether the monitoring server communication unit 11 is a device that can be connected using a set of a plant code that identifies a plant (power plant) and a unit code that identifies a facility (for example, a power plant) in the power plant. Assume the case to do. In that case, the monitoring server communication unit 11 may perform the encryption using a protocol that supports encryption (for example, https), and may distribute the random number table using the same or another protocol (for example, https).

  The monitoring server communication unit 11 detects the difference between the communication data and the difference between the random number tables to determine whether or not the random number tables match. When the monitoring server communication unit 11 determines that the monitoring server communication unit 11 and the monitoring control system communication unit 23 use different random number tables as a result of the detection, for example, the monitoring server communication unit 11 sends a monitoring control system to the monitoring control system 11. A random number table is transmitted to the communication means 23. Thereby, the supervisory control system communication means 23 can update the stored random number table with the received random number table.

  On the other hand, when a normal datagram is transmitted / received, the datagram to be transmitted / received is encrypted by this random number table, so that communication with a simple but sufficient safety is possible. By arbitrarily defining a low-cost protocol as described above, communication safety and stability can be ensured.

On the other hand, general security measures such as providing VPN (Virtual Private Network) such as RSA (Rivest Shamir Adleman) public key cryptosystem and a firewall with sufficient throughput are also effective and possible. Any combination may be used.
The monitoring server 1 and the plant monitoring control system 2 may be directly connected by a dedicated line. Thereby, the safety and stability of this communication can be ensured most effectively.

  On the other hand, the terminal device 3 transmits and receives data related to the service of the monitoring server 1 via the monitoring server 1 and the communication circuit network 4. Thereby, the engineer who uses the terminal device 3 can use the service of the monitoring server 1. The monitoring server 1 authenticates the service user, but the terminal device 3 may be an arbitrary device. Moreover, there is no restriction | limiting in the installation place of the terminal device 3. FIG.

  In general, the service of the monitoring server 1 may be provided in the form of a Web service using a protocol such as http, or via dedicated application software.

  With the configuration described above, an engineer can use various services of the monitoring server 1 by using the terminal device 3, for example.

(effect)
According to the configuration of the first embodiment, the data management unit 12 in the monitoring server 1 stores and manages various types of information as plant information for each plant. The data management means 12 stores registration information such as plant-specific names, device combinations, device names, use / non-use of devices, and device state changes (for example, trend graph patterns).

  Thereby, the device monitoring means 14 displays the name, device configuration, current state, alarm state, and device combination state called in each plant in time series by combining the state monitoring data and these registration information. Generated information. Then, the device monitoring unit 14 transmits the generated information to the terminal device 3 via the communication circuit network 4. And the terminal device 3 receives these information, and displays these information. Thereby, the engineer who uses the terminal device 3 can browse these information.

  As described above, the monitoring server 1 collectively manages the data of a plurality of plants, so that the engineer can obtain the information from the terminal device 3 with no restrictions on the installation location. As a result, for example, in order to carry out engineering for updating the control target equipment for a specific plant, as in the past, an engineer is assigned to the target plant in order to check whether the contents of the book are accurate. You can eliminate the trouble of whispering.

  As an example, the monitoring server 1 is arranged at an engineering base where the terminal device 3 is installed, thereby facilitating maintenance of the monitoring server 1. Even if a failure or abnormality occurs in the monitoring server 1, if the monitoring server 1 is in the engineering base, the engineer can repair it immediately.

(Example 2)
Next, Example 2 will be described. In this embodiment, the object of failure monitoring and failure analysis is expanded not only to the component devices of the plant monitoring control system but also to the plant component devices (for example, pumps, electric motors, valves, sensors, etc.) that are the devices to be controlled. It is an example which shows performing failure monitoring and failure analysis.

  In the present embodiment, the above-described failure monitoring and failure analysis are performed by the monitoring server communication means 11 of the server 1, the equipment monitoring means 14, the data management means 12, and the monitoring operation means 22 arranged in the plant monitoring control system 2. This is realized by the system communication means 23.

The processing in the present embodiment will be described with reference to FIGS.
Here, FIG. 4A is an example of the monitoring room screen G21 displayed on the terminal device 3 in the second embodiment. The monitoring room screen G21 schematically represents the entire control equipment room of the plant. A controller in the control device room is schematically shown. A schematic diagram may be superimposed and displayed on an image obtained by capturing an actual controller. In FIG. 4A, an asterisk blinks on the controller 1 where the alarm is generated. For example, in the monitoring room screen G21, when the cursor moves to the target controller 1 and the terminal device 3 receives a predetermined operation (for example, left click) using the mouse, the device monitoring unit 14 displays the screen in FIG. Transition to the controller screen G22 of B).

  First, in order to display a failure of a component device of the plant monitoring control system 2 as shown in FIG. 4A, the data management means 12 of the monitoring server 1 includes plant design data, device configuration information, and arrangement. The design data that has been determined is stored. The equipment monitoring means 14 can generate the display data of the control equipment room of the plant shown in the three-dimensional graphic by the procedure shown in FIG. 5 described later.

  On the other hand, in the plant monitoring control system 2, in parallel with the operation monitoring of the plant, it is regularly monitored whether or not each device in the system has failed. When a failure occurs, a mechanism for notifying the failure is provided. Built-in. Data notifying this failure is also transmitted from the plant monitoring control system 2 to the monitoring server 1 and managed by the data management means 12.

  Therefore, the device monitoring means 14 performs the process shown in FIG. 5 to generate the three-dimensional image data as described above and refer to the data designed for the layout of the failed device to determine the layout of the corresponding device. Along with this, a mark indicating various failures and various displays can be performed.

  FIG. 4B is an example of a controller screen G22 that performs a failure analysis for the plant component device in the second embodiment. In FIG. 4 (B), the schematic diagram of a control object apparatus, a pump, and a valve is shown. It is also shown that the control is automatic and the valve is closed.

  The device monitoring unit 14 recognizes the display content already generated by itself. Therefore, for example, when the mouse of the terminal device 3 is clicked when the screen of FIG. 4A is displayed on the terminal device 3, the terminal device 3 transmits a click signal to the monitoring server 1. In this case, the device monitoring unit 14 can display a detailed display like the controller screen G22 in FIG. 4B by accepting the enlargement request by the click signal.

  When returning to the original monitoring room screen G21, the engineer uses, for example, another button of the mouse, an icon displayed in the screen, or a “return to previous screen” function provided in the Web browser. You can return to the original monitoring screen.

Next, the monitoring screen generation process in the monitoring server 1 will be described with reference to FIG. FIG. 5 is a diagram for explaining monitoring screen generation processing in the monitoring server 1 in the second embodiment.
First, the monitoring server communication unit 11 receives plant data from the plant monitoring control system 2. The data management unit 12 stores the plant data received by the monitoring server communication unit 11 in a current value management DB (database) that manages the current situation.

  The data management unit 12 extracts failure detection data and machine abnormality data from the current value management DB, and outputs abnormality management data including the extracted failure detection data and machine abnormality data to the device monitoring unit 14.

  The equipment monitoring unit 14 acquires plant design data from the data management unit 12, for example. Here, the plant design data is data representing the arrangement positions and connection relationships of the devices (for example, the controller 21) and the control target devices that constitute the plant monitoring control system in the target plant. For example, the equipment monitoring unit 14 obtains equipment data (display location data) included in the location to be displayed on the screen from the acquired plant design data. The display location data is, for example, device data included in the monitoring room screen or the controller screen. Then, the device monitoring unit 14 generates, for example, image data (designated area data) of an area to be displayed on the screen.

  For example, the device monitoring unit 14 acquires the abnormality management data stored in the data management unit 12 as alarm data. In addition, the device monitoring unit 14 acquires device configuration data from the data management unit 12, for example. Here, the equipment configuration data is data of equipment constituting the target plant. For example, the device monitoring unit 14 determines a position where an abnormality or a failure has occurred using the acquired device configuration data and alarm data. And the apparatus monitoring means 14 determines the position of abnormality or failure (abnormal failure display position) in the image indicated by the designated area data, for example, based on the determined position and the designated area data.

  For example, the device monitoring unit 14 generates display data in which a specific mark (for example, an asterisk) is added to the determined abnormal failure display position in the image indicated by the designated area data. For example, the device monitoring unit 14 transmits the generated display data to the terminal device 3 at a constant cycle. Thereby, the terminal device 3 can display a monitoring screen or a controller screen at this fixed cycle.

  Subsequently, failure analysis of the plant component equipment using the equipment monitoring means 14 will be described with reference to FIG.

  FIG. 6 is an example of a failure analysis display screen of a plant component device in the second embodiment. The screens G31 to G33 are examples of screens displayed on the terminal device 3. The screen G31 is an example of a screen that displays plant alarm information. On the screen G31, a table in which an alarm identification number, an occurrence date and time, and an abnormality content are associated is shown.

  The screen G32 is an example of an alarm detail display screen that is transitioned to when “Details” is clicked on the screen G31. On the screen G32, a graph showing a temperature monitoring trend is shown. The vertical axis of this graph is temperature, and the horizontal axis is time. The temperature detected by the temperature sensor from-[alpha] minutes to + [beta] minutes is shown with reference to the alarm occurrence time (time t = 0).

  The screen G33 is an example of an alarm advice screen that is transitioned to when “advice” is clicked on the screen G31. On the screen G33, warning advice is displayed. In this example, the frequency of recently occurring abnormalities and the corresponding advice are displayed, and the engineer confirms the frequency of occurrence of the alarm and shows what action should be taken.

  As shown in FIG. 6, in order to display the failure of the plant component equipment, the data management means 12 of the monitoring server 1 stores the design data of the plant and the design data that determines the configuration data of the plant equipment. Here, the plant design data is data indicating how the plant equipment is combined. The design data of the plant includes, for example, the piping configuration of the plant and the position of the plant equipment. The configuration data of plant equipment is data indicating the configuration of the plant equipment itself.

  The equipment monitoring means 14 can generate the display data of the failure analysis display screen of the plant constituent equipment according to the procedure shown in FIG.

  On the other hand, the plant monitoring and control system 2 periodically monitors each plant component device as plant operation monitoring, and transmits data informing the failure or abnormality to the monitoring server 1 when a failure or abnormality occurs. Thereby, the data management means 12 can manage the failure information or abnormality information of each plant component apparatus.

  Therefore, by performing the process shown in FIG. 7 in the device monitoring unit 14, a screen for failure analysis can be displayed with reference to the layout data of the failed device.

  The data management means 12 of the monitoring server 1 accumulates information of other plants, thereby analyzing the failure information of the plant constituent devices, determining the degree of abnormality, and starting to display the failure analysis result.

FIG. 7 is a flowchart illustrating an example of a flow of abnormal content display processing according to the second embodiment.
(Step S101) First, the device monitoring unit 14 refers to failure information or abnormality information held by the data management unit 12, and determines whether there is a machine abnormality. If there is a machine abnormality (YES), the device monitoring unit 14 proceeds to step S102. On the other hand, when there is no machine abnormality (NO), the device monitoring unit 14 proceeds to step S109.

  (Step S102) If it is determined in step S101 that there is a machine abnormality, the device monitoring unit 14 performs processing for registering the machine abnormality in the data management unit 12, and the process proceeds to step S103.

  (Step S103) The device monitoring means 14 determines whether or not there is a new occurrence alarm. If it is a new occurrence alarm (YES), the device monitoring means 14 proceeds to step S104. On the other hand, if it is not a new occurrence alarm (NO), the device monitoring means 14 proceeds to step S108.

  (Step S104) If it is determined in step S103 that the alarm is a new occurrence alarm, the device monitoring unit 14 acquires the occurrence date and time, and proceeds to step S105.

  (Step S105) Next, the equipment monitoring means 14 additionally displays the date and time of occurrence and the details of the abnormality of this newly generated alarm on the plant alarm status display screen (for example, screen G31 in FIG. 6), and proceeds to Step S106.

  (Step S106) Next, the device monitoring unit 14 increments the alarm generation counter by one, and proceeds to step S107.

  (Step S107) Next, the device monitoring unit 14 executes advice processing described later, and proceeds to step S109.

  (Step S108) The device monitoring unit 14 continues the display and proceeds to Step S109.

  (Step S109) Next, the device monitoring means 14 detects an abnormality that is not a mechanical abnormality, and proceeds to step S110. Here, the abnormality that is not a mechanical abnormality is, for example, a temperature abnormality. For example, the device monitoring unit 14 monitors a temperature change for each predetermined period based on an output signal of a temperature sensor that measures the temperature of the plant component device, and detects a temperature abnormality when the temperature change exceeds a threshold value. .

  (Step S110) Next, the device monitoring unit 14 determines whether there is an abnormality that is not a mechanical abnormality. If there is an abnormality that is not a mechanical abnormality (YES), the device monitoring unit 14 proceeds to step S111. On the other hand, when there is no abnormality that is not a mechanical abnormality (normal) (NO), the device monitoring unit 14 proceeds to step S114.

  As an example of a specific process in step S110, the equipment monitoring unit 14 determines whether the plant component equipment (for example, a gas turbine) is in a state where the intake air temperature is lowered even though there is no change in the fuel input amount and the intake air amount. When the output decreases, it is determined that there is an abnormality. On the other hand, the equipment monitoring unit 14 determines that there is no abnormality (normal) when the output of the plant component equipment (for example, gas turbine) increases when the intake air temperature is lowered.

  For example, the data management means 12 may store data indicating the relationship between environmental conditions (for example, temperature and pressure conditions), the amount of fuel to be input, and the range of the amount of heat to be discharged. . In that case, the device monitoring unit 14 reads out from the data management unit 12 the range of heat quantity corresponding to the set of the observed environmental conditions and the amount of fuel that is currently input. Then, the device monitoring means 14 determines that there is an abnormality when the current amount of heat is not within the range of this amount of heat, and determines that there is no abnormality when the current amount of heat is within the range of this amount of heat. Also good.

  (Step S111) If it is determined in step S110 that there is an abnormality, the equipment monitoring unit 14 displays the abnormality on the plant alarm display screen, and the process proceeds to step S112.

  (Step S112) Next, the device monitoring unit 14 increments the alarm generation counter by 1, and proceeds to Step S113.

  (Step S113) Next, the device monitoring unit 14 executes advice processing described later, and proceeds to step S114.

  (Step S114) Next, the device monitoring unit 14 completes the display of the abnormality displayed on the screen of the terminal device 3, and proceeds to step S115.

  (Step S115) Next, the device monitoring unit 14 stores the details of the alarm in the data management unit 12, and proceeds to step S116.

  (Step S116) Next, the device monitoring unit 14 investigates the day and the abnormality that has occurred in the past week from the day. Specifically, for example, the device monitoring unit 14 extracts data on an abnormality that has occurred in the past week from the current day from the data management unit 12, and analyzes the tendency of the extracted data. Then, the device monitoring unit 14 proceeds to step S117.

  (Step S117) Next, the device monitoring unit 14 adds the tendency obtained by the analysis to the advice data stored in the data management unit 12. For example, when the abnormality occurrence frequency is 2 to 3 times, advice data “Let's pay attention to XXX” is added. Further, for example, when the abnormality occurrence frequency is 4 times or more, advice data “XXX frequently occurs” is additionally written. Thereby, the apparatus monitoring means 14 can display the tendency of the abnormality that has occurred as shown in the screen G33 in FIG.

FIG. 8 is a flowchart showing an example of the advice processing in steps S107 and S113 of FIG.
(Step S201) First, the device monitoring unit 14 executes alarm advice processing. Specifically, for example, the device monitoring unit 14 executes the process assigned to the node described as “44” in the failure analysis tree data illustrated in FIG. 11, and proceeds to step S202.

  (Step S202) Next, the device monitoring means 14 determines whether or not the current time is the collection time of the number of alarm occurrences. The collection time of the number of alarm occurrences is, for example, one predetermined time in one day. Here, as an example, the collection time of the number of alarm occurrences is 0:00 AM. If the current time is the collection time of the number of alarm occurrences (YES), the device monitoring unit 14 proceeds to step S203. On the other hand, if the current time is not the collection time of the number of alarm occurrences (NO), the device monitoring unit 14 proceeds to step S207.

  (Step S203) When it is determined in step S202 that the current time is the collection time of the number of alarm occurrences, the device monitoring unit 14 collects the occurrence of the abnormality on the previous day for each alarm. For example, as shown in FIG. 9, when the alarm A is sounded and the alarm A signal changes from 0 to 1, the device monitoring means 14 changes from 0 to 1 for the alarm A signal for one day. Is counted, and the process proceeds to step S204.

  (Step S204) Next, the device monitoring means 14 creates a table indicating the frequency of occurrence of each alarm as shown in the example of FIG. 10 within a predetermined analysis execution range, and proceeds to step S205.

  (Step S205) Next, the device monitoring unit 14 compares the result shown in the created table with the criterion assigned to the node described as “44”, and proceeds to step S206.

  (Step S206) Next, as a result of the comparison in step S205, the device monitoring unit 14 determines whether or not a predetermined advice condition is satisfied. When the predetermined advice condition is satisfied (YES), the process proceeds to step S207. If the predetermined advice condition is not satisfied (NO), the device monitoring unit 14 ends the routine of this flowchart.

  (Step S207) When it is determined in Step S206 that the predetermined advice condition is satisfied, the device monitoring unit 14 adds the advice corresponding to the advice condition to the advice data stored in the data management unit 12.

  As described above, when a new alarm is generated, the device monitoring unit 14 counts up the alarm generation counter, and summarizes the number of alarm generations for the previous day for each alarm when the daily change occurs. The device monitoring means 14 analyzes this, for example, in the past week or more, and gives a warning and warning according to the number of occurrences.

  FIG. 9 is a diagram illustrating an example of a signal change of the alarm A signal according to the second embodiment. The alarm A signal takes a value of 0 or 1 as time-series data sampled at a predetermined sampling period. 0 indicates that the alarm is not sounding, and 1 indicates that the alarm is sounding.

  FIG. 10 is an example of a table indicating the frequency of occurrence of each alarm for each day in the second embodiment. In the table of FIG. 10, the frequency for each day from the previous day to 7 days before is stored for each alarm.

  When the processing of FIG. 8 is performed up to a certain number of times, the device monitoring unit 14 displays a currently occurring alarm, and gives advice on a past alarm occurrence tendency and a frequently occurring alarm. Thereby, for example, when the terminal device 3 is installed in the target plant, the maintenance staff of the target plant using the terminal device 3 can grasp the alarm, and pay attention to the facility operation of the plant. This makes it possible to operate the equipment for a long time.

(Failure analysis processing)
The data management means 12 stores failure analysis tree data shown in FIG.
FIG. 11 is an example of failure analysis tree data according to the second embodiment. Failure analysis tree data is data in which each node is connected by a link, and each node is associated with information to be displayed and information on which node is to be transitioned according to the engineer's response to that advice. Yes. For example, when the current node is “44”, the device monitoring unit 14 transitions to either “43” or “24” according to the response of the engineer.

  As described above, when the engineer responding to the advice makes a response, the device monitoring unit 14 determines the next node according to the response and displays the advice assigned to the next node. This advice includes advice on which page of the book created in FIG. 15 described later can be solved. The equipment monitoring unit 14 repeats this, so that the engineer can correctly execute the processes up to data collection and cause determination without having to take a necessary procedure at the time of failure.

Next, a diagnostic screen generation process in the monitoring server 1 will be described with reference to FIG. FIG. 12 is a diagram for explaining the diagnostic screen generation process in the monitoring server 1 in the second embodiment.
First, the monitoring server communication means 11 receives plant data from the plant monitoring control system 2, for example. And the data management means 12 stores the plant data which the monitoring server communication means 11 received, for example in present value management DB (database) which manages the present condition.

  For example, the data management unit 12 extracts failure detection data and machine abnormality data from the current value management DB, and outputs the abnormality management data including the extracted failure detection data and machine abnormality data to the device monitoring unit 14.

  The equipment monitoring unit 14 acquires plant design data from the data management unit 12, for example. For example, the device monitoring unit 14 acquires data (plant device data) related to plant constituent devices from the acquired plant design data.

  For example, the device monitoring unit 14 acquires the abnormality management data stored in the data management unit 12 as alarm data. In addition, the device monitoring unit 14 acquires failure analysis tree data from the data management unit 12, for example. The device monitoring unit 14 determines a device to be diagnosed using the acquired failure analysis tree data and alarm data. Here, the equipment to be diagnosed includes plant constituent equipment and equipment constituting the plant monitoring control system 2.

  Specifically, for example, the device monitoring unit 14 determines a start node from the nodes included in the failure analysis tree data. The device monitoring unit 14 acquires, for example, advice associated with the start node from the data management unit 12 as failure diagnosis data. And the equipment monitoring means 14 produces | generates display data using the acquired failure diagnosis data and plant equipment data. The device monitoring unit 14 transmits the generated display data from the monitoring server communication unit 11 to the terminal device 3. Thereby, in the terminal device 3, display data is received and the received display data is displayed as a diagnostic screen initial screen.

  The terminal device 3 receives user input and transmits input information indicating the received user input to the monitoring server 1. The monitoring server communication unit 11 receives this input information and outputs it to the device monitoring unit 14. The device monitoring unit 14 changes the node of the failure analysis tree data in accordance with the input information input from the monitoring server communication unit 11, and uses the advice assigned to the node after the transition as failure diagnosis data from the data management unit 12. get. And the equipment monitoring means 14 produces | generates display data using the acquired failure diagnosis data and plant equipment data. The device monitoring unit 14 transmits the generated display data from the monitoring server communication unit 11 to the terminal device 3. Thereby, in the terminal device 3, display data is received and the received display data is displayed as a diagnostic step screen. The terminal device 3 and the monitoring server 1 analyze the failure by repeating this series of processes.

  In this way, when the device monitoring unit 14 displays advice along the failure analysis tree data shown in FIG. 11, as an advice, which page of the book shown in FIG. indicate. As a result, the maintenance staff of the target plant using the terminal device 3 can respond without hesitation.

(effect)
According to the processing of the second embodiment, the information processing system 100 can provide the same maintenance service not only for the component devices of the plant monitoring control system 2 but also for the plant component devices, thereby ensuring stable operation of the plant. It is possible to provide more advanced maintenance services to the expected customers.

Example 3
Subsequently, Example 3 of the present invention will be described.
In this embodiment, in addition to the engineering means 13 provided in the monitoring server 1, the data management means 12, and the monitoring server communication means 11, the monitoring operation installed in the plant monitoring control system 2 is performed from a place away from the plant. This is realized by means 22 and monitoring control system communication means 23.

The monitoring server communication unit 11 receives from the terminal device 3 a control target device specified by the user who uses the terminal device 3.
The engineering unit 13 causes the monitoring server communication unit 11 to transmit the control target device identification information for identifying the control target device or the address corresponding to the control target device from the monitoring server communication unit 11 to the plant monitoring control system 2. In response, the monitoring server communication unit 11 transmits the state information relating to the state of the control target device from the monitoring server communication unit 11 to the terminal device 3.

The data management unit 12 stores engineering data including at least one of a control program for controlling the control target device and a parameter for controlling the control target device.
In addition, the monitoring server communication unit 11 receives from the terminal device 3 the creation or change of a parameter for controlling the control program or the control target device instructed by the user.

The engineering unit 13 applies the creation or change received by the monitoring server communication unit 11 to the engineering data stored in the data management unit 12, and part or all of the engineering data after application is applied from the monitoring server communication unit 11. It is transmitted to the plant monitoring control system 2.
The plant supervisory control system 2 controls the control target device using a part or all of the engineering data transmitted from the monitoring server communication unit 11.

The data management means 12 stores work identification information for identifying a work and a data set necessary for the work identified by the work identification information in association with each other.
The monitoring server communication unit 11 receives the work selected by the user from the terminal device 3.
The engineering unit 13 acquires a data set corresponding to the work accepted by the monitoring server communication unit 11 from the data management unit 12 from the data management unit 12 and transmits the acquired data set from the monitoring server communication unit 11 to the terminal device 3. .

  The engineering unit 13 acquires data for connecting to the plant monitoring control system 2 according to the work identification information, and causes the monitoring server communication unit 11 to communicate with the plant monitoring control system 2 using the acquired data. At least one of the execution status of the control program executed by the plant monitoring control system 2, the control program, and the parameters of the control program is acquired.

  In the embodiment configured as described above, for example, when engineering a control program, an engineer using the terminal device 3 creates a control program as shown in FIG. 13 by using the function of the engineering means 13. Can be changed, changed, or referenced. FIG. 13 is a diagram illustrating an example of a control program according to the third embodiment. This control program is a program for determining the signal value of the signal E according to the signal values of the signal A, the signal B, the signal C, and the signal D.

  Further, when used for engineering applications of plant equipment, for example, the engineering unit 13 causes the monitoring server communication unit 11 to transmit CAD data, electronic purchase data, or the like to the terminal device 3. Thereby, the terminal device 3 displays this CAD data or electronic purchase data. Thereby, an engineer who uses the terminal device 3 can refer to, create, or change CAD data or electronic purchase data.

  The engineering means 13 is, for example, a combination of elements as shown in FIG. FIG. 14 is a schematic block diagram showing the configuration of the engineering means 13 in the third embodiment. The engineering unit 13 includes an engineering management function unit 131, an integrated user interface 132, and an interface 133.

The integrated user interface 132 is an interface for selecting work to be performed by an engineer.
The interface 133 is an interface for acquiring a data set necessary for work from the data management unit 12.

Data sets required for engineering work are integrated and managed in the data management means 12 of the monitoring server 1.
The integrated user interface 132 accepts work information indicating work designated by an engineer using the terminal device 3 from the terminal device 3 via the monitoring server communication unit 11, and the work indicated by the accepted work information is performed by the engineer. select.

The engineering management function unit 131 obtains a data set necessary for work from the data management unit 12 through the interface 133, and services (for example, service A) from a basic data set (master image) that holds a combination of the CADs compatible with the data set. , Service B,..., Service n). Here, the service is provided for each type of engineering target. The service is, for example, a service for a turbine or a service for a boiler. The basic data set is a data set serving as a base for each service.
This corresponds to, for example, processing in which the engineer selects and uses an engineering machine according to the work in the engineering means 13.

  For example, when engineering (for example, creating or changing) a control program, the engineer specifies that the control program is to be engineered from the integrated user interface 132 displayed on the terminal device 3.

  At this time, when the engineer designates the control program in detail and tries to monitor or change the current program of the plant, for example, the monitoring server 1 executes the following processing. The interface 133 of the engineering unit 13 acquires data for connecting to the plant 2 from the data management unit 12 in response to a request given to the engineering management function unit 131. And the interface 133 connects to the plant monitoring control system 2 installed in the plant through the monitoring server communication means 11 and the monitoring control system communication means 20 using the acquired data.

  Thus, the engineering means 13 provides the function of the engineering tool of the plant monitoring control system 2. Thereby, the engineer can use the service of the engineering means 13 of the monitoring server 1 in the terminal device 3. As a result, the engineer can monitor the actual operation of the control program, the value being calculated, and the like. In some cases, the engineer can change the parameters or the control program itself.

  Unlike the prior art, in this embodiment, the service of the engineering means 13 can be used wherever the terminal device 3 is installed, so that it is possible to eliminate the trouble of the engineer going to the plant for engineering. Further, in the present embodiment, unlike the conventional case, engineering data such as a control program is collectively managed in the data management means 12, so that consistency of the engineering data is ensured.

  On the other hand, when an engineer designs a plant, for example, by using a data set corresponding to this, a monitoring server is also used for plant design, for example, instrument arrangement design as well as the above control program engineering. 1 and the terminal device 3 connected thereto can be used.

Moreover, the engineering means 13 provides a service for all plant components of all plants. The data management unit 12 stores a basic data set.
For example, the engineering management function unit 131 acquires a basic data set from the data management unit 12 and provides a service using the basic data set. For example, when the data set is changed in the service A of a certain plant A, the engineering management function unit 131 changes the basic data set corresponding to the service A. Thereby, the engineering management function part 131 can provide the service B to the other plant B using the changed basic data set.

  As described above, when a data set is changed in a certain service, the basic data set is changed, and a service is provided for another brand using the changed basic data set. For this reason, it is possible to eliminate the redundant change of the data set, and to reduce the labor of the engineer. In addition, since the basic data set is changed, the service provided next uses the changed basic data set, so that the quality of the service provided next can be improved.

  As described above, in the third embodiment, the information processing system 100 includes the monitoring control system communication unit 23 in addition to the engineering unit 13, the data management unit 12, and the monitoring server communication unit 11 included in the monitoring server 1. An engineering environment optimal for the engineering work performed by the engineer can be provided to the terminal device 3 used by the engineer.

  When a data set is changed in one service, the basic data set is changed, and another service is provided using the changed basic data set. For this reason, it is possible to eliminate the redundant change of the data set, and to reduce the labor of the engineer.

  In addition, since engineering data is collectively managed in the data management means 12, engineering can be performed while ensuring consistency. Therefore, it is possible to reduce the labor of the engineer compared to the conventional technique and perform engineering while ensuring consistency.

Example 4
Next, Example 4 will be described with reference to FIGS. 15, 16, and 17.
In this embodiment, in addition to the engineering means 13, the data management means 12, the book management means 15, and the monitoring server communication means 11 provided in the monitoring server 1, the monitoring operation means 22 and the monitoring provided in the plant monitoring control system 2 are managed. This is realized by the control system communication means 23. Here, the book is a medium for expressing the result of engineering.

FIG. 15 is an example of a screen displayed on the terminal device 3 in the fourth embodiment.
FIG. 15A is an example of a screen G131 displayed on the terminal device 3, and is displayed for a certain data set. When the “specification download” button is pressed, the terminal device 3 transitions to the screen of FIG.
FIG. 15B is an example of a screen G132 on which information of one page included in the system specification S13 is displayed.

  FIG. 16 is an example of a list of items of books created in the fourth embodiment. FIG. 16 shows a table in which book items, contents, and remarks are associated with each other.

FIG. 17 is a diagram for explaining processing in the monitoring server 1 when the fourth embodiment is realized.
The data management unit 12 stores at least control target device information regarding the control target device.
The engineering unit 13 changes part or all of the information stored in the data management unit 12. The engineering unit 13 outputs the changed information to the book management unit 15.
The book management means 15 manages the information after the engineering means 13 has changed in a predetermined data format.

In the example of FIG. 17, the engineering means 13 has changed the data represented by white circles, black circles, and triangles in the engineering data D131.
In this case, the change in the engineering data D131 is reflected by the book management means 15 in the data D132 having a predetermined data format.

  The book management means 15 holds a book number which is an example of information for identifying a book. For example, when the book number is represented by a set of plant component equipment classification, book format (style), and serial number, the book management means 15 uses the data D132 of a predetermined data format as the book number. Store it in association. Here, as an example, the serial number is information that uniquely identifies the data D132. Note that the serial number may be information for identifying a style.

  The book number may be represented by a set of style, category, department code, and serial number.

  When the engineer operates the engineering means 13 to complete a certain work process, the book management means 15 creates a book. In other words, the book displays engineering data that takes into account the changes made to the data management means 12 as a result of the engineer's work, in an appropriate format.

The book management unit 15 generates data in which engineering data stored in the data management unit 12 as a result of using the engineering unit 13 is arranged in a predetermined format.
Therefore, in order to make the data reflecting the work result of the engineering means 13 into the book, the book management means 15 acquires the required book format and the data contained in the format from the data management means 12. And the book management means 15 can produce | generate appropriate book data by arrange | positioning data according to the format of the acquired book.

  For example, the description items of books such as specifications for the plant monitoring control system 2 are generally described in a structural manner. In the present embodiment, the book management means 15 collectively generates the specifications of the plant monitoring control system 2, but it is also a method of structurally generating data according to structured description items. Good. For example, the book management means 15 can easily realize this method by changing the query for inquiring the data management means 12 at the time of data acquisition and the format (for example, represented by a style sheet on the Web).

  In the present embodiment, for example, when the plant operator intentionally changes the setting value to be compared when determining whether or not the measured value is abnormal, the book management unit 15 stores the past stored in the data management unit 12n. By referring to the history, etc., an engineering decision is made as to whether or not this set value is reflected in the book. Here, the past history is, for example, a past operation history of the plant component device.

  Specifically, for example, it is assumed that the plant operator changes the set value from 38 degrees to 39 degrees when the measured value is a temperature value detected by a temperature sensor installed in a certain plant. In the past operation history of the plant, if the plant component equipment of the plant is operating normally even after setting the setting value to 39 degrees, the book management means 15 determines that the setting value is reflected in the book.

  When the book management means 15 determines that the set value is reflected in the book, the book management means 15 reflects the setting value in the book.

(effect)
According to the present embodiment, the book management unit 15 acquires the necessary book format and data stored in the format from the data management unit 12. And the book management means 15 can produce | generate an appropriate book by arrange | positioning data according to the format of the acquired book.

  As a result, the engineering that mainly uses the book is changed to the engineering that mainly uses the data. For example, when the book is newly created by diverting the design drawing, the book management means 15 generates the book data in a predetermined format. . For this reason, it is possible to always generate a book with a constant quality regardless of the skill and experience of the engineer.

  Conventionally, when design data from a related department is to be used in engineering of the own department, it has been necessary to devote considerable man-hours to understand the meaning of the data and to process the book optimally to create a book. On the other hand, according to the present embodiment, the book management means 15 generates the book data by arranging the engineering data centrally managed by the data management means 12 in a predetermined format. Can be reduced.

(Example 5)
Subsequently, Example 5 will be described with reference to FIGS. 18 and 19.
The virtualization means 16 (see FIG. 3) realizes a virtual plant in its own apparatus based on information related to the specification of the control target device and information related to the design of the entire plant. And the virtualization means 16 carries out the simulation operation | movement of the control program which the plant monitoring control system 2 performs in this virtual plant. And the virtualization means 16 estimates the operation | movement of a plant by operating the plant simulator corresponding to this. As a result, the engineer can confirm the operation in the same manner as when the operation is confirmed using the actual machine.

The plant is designed and manufactured by an engineer, and actually operates. In a plant, various devices and a plant supervisory control system for operating these devices operate in a complex manner.
However, with recent advances in simulation technology, emulation technology, and scientific calculation technology, various practical simulations can be performed using virtualization technology represented by, for example, Xen.

  Under such a basic technology, for example, an actual plant monitoring and control system 2 as shown in FIG. 18 is installed in a plant, combines dedicated components, connects each device via a network, and operates plant components.

  FIG. 18 is a schematic block diagram illustrating a configuration of a plant according to the fifth embodiment. In the plant, a control target device 70 and a plant monitoring control system 2b connected to the control target device 70 are installed. Here, one control target device 70 is shown as a representative of the plant component device, but a plurality of plant component devices are installed in the actual plant.

  The plant supervisory control system 2b includes supervisory control system communication means 23, supervisory operation means 22, and controllers C1, C2, C3, C4 and C5. The monitoring control system communication unit 23, the monitoring operation unit 22, and the controllers C1, C2, C3, C4, and C5 are connected to each other via the LAN 25.

  One of the controllers C1, C2, C3, C4, and C5 performs, for example, monitoring and control of plant component equipment.

  The terminal device 3 uses the service of the engineering means 13 in the monitoring server 1 via the communication circuit network 4. Thereby, the engineer who uses the terminal device 3 can monitor and control the plant component equipment.

  FIG. 19 is an example of a configuration in which the plant and the plant monitoring control system 2 in the fifth embodiment are simulated by the monitoring server 1. In FIG. 19, the virtual environment 6 generated by the engineering means 13 is shown. The virtual environment 6 includes a simulated plant monitoring control system 2 c simulated by the monitoring server 1 and a simulated plant 7 simulated by the monitoring server 1.

  The simulated plant monitoring control system 2c is a virtual system that simulates the plant monitoring control system 2b of FIG. The simulated plant monitoring control system 2c includes a monitoring operation unit 22, a monitoring control system communication unit 23, and controllers C1, C2, C3, C4, and C5. These components are virtual components simulated by the monitoring server 1. It is simulated that the monitoring operation unit 22, the monitoring control system communication unit 23, and the controllers C1, C2, C3, C4, and C5 are connected to each other via the LAN 25.

  The simulation plant 7 includes a pump 71, a sensor 72, and a valve 73. These components are virtual components simulated by the monitoring server 1.

The engineering data created by the engineering means 13 is stored in the data management means 12.
The virtualization means 16 acquires engineering data from the data management means 12, and uses the resources of the monitoring server 1 specified by the engineering means 13 based on the acquired engineering data to simulate the plant monitoring control system. Create a virtual environment.

In the same manner, the data management unit 12 also integrally manages engineering data related to plant component equipment and overall plant design.
Therefore, the virtualization means 16 can similarly build a simulation plant in the monitoring server 1 based on this engineering data.

  For example, the virtualization unit 16 generates model data of sensors, pumps, valves, and the like, connects them according to the plant piping design data, and similarly generates a model that simulates a circuit breaker and a relay circuit.

When such detailed models are interconnected, errors in model-based computation results may be collected and the simulated operation may fail as a whole.
However, these calculation errors are based on, for example, the dynamic characteristics of the plant obtained in the same manner after giving the data collected by the plant monitoring control system 21 of the plant that is already actually operating as an initial value. Predictive correction is possible.

  Thus, if the simulation plant 7 and the simulation plant monitoring control system 2c are comprised in the monitoring server 1, it will operate | move similarly to an actual plant. As a result, it has become possible for the monitoring server 1 to perform operations that have conventionally been confirmed for operation using an actual device. As a result, since the operation can be confirmed from the terminal device 3, it is possible to reduce the trouble of the engineer going to the plant and actually constructing the environment using the equipment for performing the test. As a result, the test time can be greatly shortened and the cost can be reduced.

  Thus, for example, when designing a plant monitoring control system according to a newly constructed plant, a practical plant simulator and emulation technology are used at the design stage, production stage and pre-shipment testing stage of the plant monitoring control system. By utilizing the above, it is possible to reduce the controllability regarding the parameters (for example, the number of parameters that can be changed or the variable range of each parameter).

  In addition, after the plant monitoring and control system, which is actually composed of various components, is shipped from the manufacturing base and the plant component equipment and the plant monitoring and control system are actually connected, the control characteristics can be improved according to the operation of the plant component equipment. Assume when it is necessary. Even in such a case, since the test can be performed from the terminal device 3 using the virtual environment, the test time can be greatly shortened and the cost can be reduced.
