Hereinafter, the present invention will be described with reference to the drawings and embodiments of the invention. However, the following embodiments do not limit the invention within the scope of the patent application. Moreover, all combinations of features described in the embodiments are not necessarily required for the solution of the invention. of. The same or equivalent constituent elements, members, and processes shown in the various drawings are denoted with the same symbols, and repeated descriptions are appropriately omitted.

Fig. 1 is a schematic diagram showing the overall configuration of a factory according to an embodiment of the present invention. First, the structure of the factory 1 targeted by this embodiment will be described using FIG. 1. Plant 1 is, for example, a power generation plant (incineration plant) including a circulating fluidized bed boiler (Circulating Fluidized Bed type). It is equipped with a boiler that circulates circulating materials such as silica sand that flow at high temperatures while burning fuel to generate steam. By. As the fuel for the plant 1, in addition to fossil fuels such as coal, non-fossil fuels (woody biomass, waste tires, waste plastics, sludge, etc.) can also be used, for example. The steam generated in the factory 1 is used to drive the turbine 100. In addition, the plant targeted by the present invention is not limited to a power generation plant or an incineration plant including a boiler, and a chemical plant, a waste water treatment plant, etc., may be plants that can obtain process data.

The factory 1 is configured to burn fuel in the furnace 2 and separate circulating materials from the exhaust gas by the cyclone 3 functioning as a solid-gas separator, and return the separated circulating materials to the furnace 2 for circulation. The separated circulating material is sent back to the lower part of the furnace 2 through the circulating material recovery pipe 4 connected below the cyclone 3. In addition, the lower part of the recycled material recovery pipe 4 and the lower part of the furnace 2 are connected via a ring-shaped seal part 4a in which the flow path is reduced. As a result, a predetermined amount of recycled material is stored in the lower part of the recycled material recovery pipe 4. The exhaust gas from which the circulating material has been removed by the cyclone 3 is supplied to the rear flue 5 via the exhaust gas flow path 3a.

The boiler is equipped with a furnace 2 for burning fuel and a heat exchanger for generating steam and the like using the heat obtained by the combustion. A fuel supply port 2a for supplying fuel is provided in the middle part of the furnace 2, and a gas outlet 2b for discharging combustion gas is provided in the upper part of the furnace 2. The fuel system supplied to the furnace 2 by a fuel supply device not shown in the figure is supplied to the inside of the furnace 2 through the fuel supply port 2a. In addition, a furnace wall pipe 6 for heating the boiler's water supply is provided on the furnace wall of the furnace 2. The boiler water supply flowing through the furnace wall tube 6 is heated by combustion in the furnace 2.

In the furnace 2, solid matter including the fuel supplied from the fuel supply port 2a is flowed by the combustion and flow air introduced from the lower air supply line 2c, and the fuel is combusted at about 800 to 900°C while flowing. . The combustion gas generated in the furnace 2 is introduced into the cyclone 3 together with the circulating material. The cyclone 3 separates the circulating material and the gas by centrifugal separation, returns the separated circulating material to the furnace 2 through the circulating material recovery pipe 4, and removes the circulating material from the combustion gas from the exhaust gas flow path 3a to the rear. Road 5 is sent out.

In the furnace 2, a part of the circulating material called the bed material in the furnace stays at the bottom. The bed material sometimes contains bed material with coarse particle size or flammable inclusions that are not suitable for circulating flow, and sometimes poor flow occurs due to the bed material that is not suitable for circulating material. Therefore, in order to suppress poor flow, in the furnace 2, the bed material in the furnace is continuously or intermittently discharged to the outside from the discharge port 2d at the bottom. The discharged bed material is supplied to the furnace 2 again or directly discarded after removing the discomforts such as metal or coarse particle size on a circulating pipeline not shown in the figure. The circulating material of the furnace 2 circulates in a circulating system composed of the furnace 2, the cyclone 3 and the circulating material recovery pipe 4.

The rear flue 5 has a flow path for the gas discharged from the cyclone 3 to flow to the rear section. The rear flue 5 has a superheater 10 that generates superheated steam and an economizer 12 that preheats the boiler water supply as a waste heat recovery part that recovers the heat of the exhaust gas. The exhaust gas flowing through the rear flue 5 is cooled by heat exchange with steam circulating in the superheater 10 and the economizer 12 or boiler water supply. In addition, there is a steam drum 8 for storing the boiler water supplied through the economizer 12, and the steam drum 8 is also connected to the furnace wall 6.

The economizer 12 transfers the heat of the exhaust gas to the boiler water supply to preheat the boiler water supply. The economizer 12 is connected to the pump 7 through a pipe 21, and on the other hand, is connected to the steam drum 8 through a pipe 22. The boiler water supply system supplied from the pump 7 to the economizer 12 via the pipe 21 and preheated by the economizer 12 is supplied to the steam drum 8 via the pipe 22.

The steam drum 8 is connected with a downflow pipe 8a and a furnace wall pipe 6. The boiler water supply system in the steam drum 8 descends in the downfall pipe 8a, and is introduced into the furnace wall pipe 6 on the lower side of the furnace 2 and circulates toward the steam drum 8. The boiler water supply in the furnace wall tube 6 is heated by the combustion heat generated in the furnace 2 and evaporates in the steam drum 8 to become steam.

The steam drum 8 is connected with a saturated steam pipe 8b for discharging the steam inside. The saturated steam pipe 8b connects the steam drum 8 and the superheater 10. The steam in the steam drum 8 is supplied to the superheater 10 via the saturated steam pipe 8b. The superheater 10 uses the heat of the exhaust gas to superheat steam to generate superheated steam. The superheated steam is supplied to the turbine 100 outside the factory 1 through the pipe 10a, and is used for power generation.

The pressure and temperature of the steam discharged from the turbine 100 are lower than the pressure and temperature of the steam discharged from the superheater 10. Although not particularly limited, the pressure of the steam supplied to the turbine 100 is about 10-17 MPa, and the temperature is about 530-570°C. The pressure of the steam discharged from the turbine 100 is about 3 to 5 MPa, and the temperature is about 350 to 400°C.

A condenser 102 is provided downstream of the turbine 100. The steam discharged from the turbine 100 is supplied to the condenser 102 and is condensed in the condenser 102 to return to saturated water and then supplied to the pump 7. The turbine 100 is connected to a generator that converts the kinetic energy obtained by the rotation of the turbine 100 into electrical energy.

The pump 7a supplies makeup water so that the water level of the condenser 102 is kept constant. Fig. 1 shows the make-up water flow rate u1 supplemented by the pump 7a.

The process data (operation data of factory 1) processed in this embodiment can be any data related to factory 1. For example, it can be data in which the state of factory 1 is measured by a sensor. More specifically, it can include factory 1 Measured values of temperature, pressure, and flow rate. In FIG. 1, the boiler water supply flow rate u2 supplied from the pump 7 to the economizer 12 is shown. In addition, in FIG. 1, the boiler outlet steam flow rate u3 supplied from the superheater 10 to the turbine 100 is shown, and the saturated steam flow rate u4 supplied from the steam drum 8 to the superheater 10 is shown. In addition, the make-up water flow rate u1 can be controlled to follow the saturated steam flow rate u4. In addition, while monitoring both the boiler outlet steam flow rate u3 (or the superheated steam flow rate) and the liquid level of the steam drum 8, the boiler water supply flow rate u2 may be controlled to follow the adjustment.

When a hole is generated in the factory 1, the make-up water flow rate u1 increases, or the flow difference between the boiler water supply flow rate u2 and the boiler outlet steam flow rate u3 increases. DCS (Distributed Control System) 20 monitors whether there is any abnormality in the process data of plant 1, such as make-up water flow u1, boiler water supply flow u2, boiler outlet steam flow u3, and saturated steam flow u4.

In addition, as process data, the make-up water flow rate u1, the boiler water supply flow rate u2, the boiler outlet steam flow rate u3, and the saturated steam flow rate u4 are shown as examples. However, the process data related to the plant 1 may also be other data. The process data related to plant 1 can be other data such as temperature and pressure.

That is, in the system 30, according to an instruction from the operator, the abnormality display function 42 is changed to any one of the abnormality detailed content display function 44, the guidance display function 50, and the evaluation item display function 52. Also, in the same manner, in the system 30, according to an instruction from the operator, the abnormality detailed content display function 44 is changed to any one of the sensor data detailed content display function 46 and the abnormality history display function 48. In addition, in the system 30, the evaluation item display function 52 is changed to the guidance display function 50 in accordance with the instruction of the operator. In addition, when each function transitions in the system 30, the display of the previous function may be replaced with the display of the next function, or the display of the next function may be displayed at the same time while maintaining the display of the previous function.

In addition, the specific operations of the various functional blocks of the aforementioned system 30 will be described in more detail in the description of using the method and display screen described later.

Hereinafter, as a method of an embodiment of the present invention, an example of a method of using the system 30 will be described. Fig. 5 is a flowchart of the method of this embodiment. 6 to 14 show an example of the display screen displayed by each function block of the system 30. Hereinafter, as an abnormal aspect that has the possibility of stopping the factory 1, a case where a burst has occurred in the factory 1 will be described as an example.

In FIG. 5, the abnormality display function 42 of the system 30 displays an abnormality display indicating the occurrence of an abnormality with the possibility of stopping the factory 1, and prompts the operator to confirm (S10). Specifically, based on a plurality of process data acquired from the factory 1 through the DCS 20, the control unit 31 of the system 30 displays an abnormality display indicating the occurrence of an abnormality.

Here, an example of the display screen DP1 based on the abnormality display function 42 will be described using FIG. 6. The display screen DP1 includes areas R10 to R15 and an evaluation item display 60.

In the area R10, "plant operation support system" is displayed as the name of the system 30, and "dashboard" is displayed as the current screen state. With the display of the area R10, it is easy to grasp which state in which system the current screen is.

In the upper left area R11 of the display screen DP1, information indicating the occurrence of an abnormality with the possibility of stopping the factory 1 and time information when the abnormality occurred are displayed. In FIG. 6, as an example of information indicating the occurrence of an abnormality that has the possibility of stopping the factory 1, the information "burst" is displayed in large-size text. The text information "2019/08/07 14:00" is displayed below it as the current time information. The current time information is automatically updated, for example, every predetermined time (for example, every 1 minute). Or, it can be updated manually by the operation of the operator. Based on the information displayed in the area R11, the operator of the factory 1 can recognize that a burst occurred at 2 pm on August 7, 2019, which is a major anomaly that has the possibility of stopping the factory 1. In addition, as a modified example, the time information immediately below the information "burst" can be set as the time when the abnormality occurred.

In the present embodiment, when it is judged that a burst has occurred (including cases where it is judged that the possibility of a burst occurring within a predetermined time is high in the future, and when it is judged that a sign of a burst has occurred. The same applies to the following) is displayed. "This information. Whether there is a burst system can be judged by comparing the process data obtained from a single sensor with a predetermined threshold. Furthermore, whether there is a burst system can be judged according to a predetermined algorithm based on the process data obtained from a plurality of sensors. The sensor includes, for example, a plurality of AE (Acoustic Emission: Acoustic emission) sensors are also included in various parts of the factory 1 and used to detect temperature, pressure, flow rate, valve opening, damper opening, liquid level, vibration, sound and other factory 1 state variables Of various sensors. In the present embodiment, the information of "burst" is displayed not only when, for example, the process data obtained from a single AE sensor shows an abnormal value exceeding a predetermined threshold. It also includes the following situation, that is, even in the case that the process data obtained from a single AE sensor does not exceed a predetermined threshold, according to a predetermined algorithm, a plurality of AE sensors, or AE sensors and Process data obtained by multiple types of sensors, such as other types of sensors, are processed and determined according to predetermined conditional expressions as a situation where the possibility of bursting is high. Therefore, compared with the case where the process data obtained from each sensor is judged based on the operator's knowledge and experience, it is possible to stably and accurately realize the early detection of bursts.

The predetermined algorithm can be based on the following mathematical formula or mathematical model, the mathematical formula or mathematical model is based on the knowledge (knowhow), empirical rules, etc. to select a plurality of sensors that affect the predetermined abnormality, by Process data of a plurality of sensors when a predetermined abnormality occurs (may include the process data before the abnormality occurs) is derived by multivariate analysis and the like. In addition, as described later, the predetermined algorithm may also be an algorithm that is dynamically generated according to a predetermined learning mode through machine learning.

In cases where it is judged that no explosion has occurred (including cases where there is no possibility of explosion in the future within 24 hours and it is judged that there is no sign of explosion. The following is the same), or if it is judged that there has been a explosion in the past, but then borrow In the case where it is determined that no burst has occurred due to predetermined measures, for example, the background color can be changed in the state where the word "burst" is displayed (for example, the background color can be changed from red to green), or change To not display the "burst" text. Therefore, when the information of "burst" is displayed in the area R11 or the background color thereof remains red, for example, the operator of the factory 1 can easily recognize that the factory 1 has reached the current time displayed directly below it. Bursts continue to occur in the medium, or continue to maintain a state with a high probability of bursts in the near future.

When it is judged that a burst has occurred, it can be emphasized by flashing its display, and when it is judged that a burst has not occurred, its display can be suppressed. In addition, when it is determined that a burst has occurred, an effect sound or sound such as a warning sound may be output. In addition, information indicating the probability of occurrence of an abnormality with the possibility of stopping the factory 1 may also be displayed in the area R11 at the same time. For example, when the probability is high, the background color of the region R11 can be red, and when the probability is low, the background color of the region R11 can be green. In this way, it is possible to intuitively grasp the probability according to the degree of the color. In addition, in order to identifiably display a plurality of abnormalities, it is possible to display text information indicating the name of the abnormality that has occurred. In addition, when it is determined that no abnormality has occurred, text information indicating that no abnormality has occurred, such as "None", may be displayed.

The operator can easily recognize the occurrence of an abnormality (including a state with a high probability of occurrence of a burst in the near future), such as a burst, which has the possibility of stopping the factory 1 through the observation area R11. In addition, the abnormality that has the possibility of stopping the factory 1 is not limited to bursting. For example, it can also be configured to detect an abnormal pipe that is clogged in the pipe due to scale (inorganic matter brought into the pipe by water supply, etc.) that gradually accumulates in the pipe of the superheater, etc., as a possibility that the plant 1 may stop. The abnormality of sex.

The area R11 includes an explanatory text 62 related to "burst". The description 62 includes the sensor that detected the occurrence of the burst or its detection method, the type of process data, the cause of the burst or its countermeasures, or the measures the operator should take next. The description 62 may include, for example, content that prompts the operator to select the "burst" display of the region R11. By displaying the explanatory text 62 related to such an abnormal display adjacent to the abnormal display, the operator can easily grasp the current status of the factory 1 and the measures to be taken next.

In the lower left area R12 of the display screen DP1, a warning display indicating the occurrence of a warning when the process data related to the factory becomes a predetermined state is displayed as "the latest warning information". The warning display shows the predetermined state of the process data that affects the operating efficiency of the plant 1. For example, it does not have the possibility of stopping the plant 1 like a burst, but it will reduce the operating efficiency of the plant 1. In the area R12, the occurrence history of the warning display is displayed in a state in which the time information indicating the occurrence time and the information indicating the content are arranged in the order of the occurrence time. For example, at the beginning of the area R12, the corresponding relationship is established and the time information "2019/08/07 13:15:00" is displayed and the content of the warning "boiler efficiency (loss method)" is displayed. News. Based on the information displayed in the area R12, the operator of factory 1 was able to recognize the warning to factory 1 that a decrease in boiler efficiency occurred under the heat loss method at 1:15:0 pm on August 7, 2019. Similarly, the operator of the factory 1 can recognize the history of time information indicating the occurrence time of the predetermined state of other process data that affects the operating efficiency of the factory 1 and the information indicating its content.

When it is determined that a warning has occurred (it may include a situation in which it is determined that a predetermined state of the process data that affects the operating efficiency will occur within a predetermined time in the future, for example), an alarm (alarm) in the area R12 is displayed. Similar to the abnormality of factory 1 such as bursting, the process data warning includes the judgment based on the process data obtained from a single sensor and the predetermined algorithm (including the dynamic generation by machine learning and according to the predetermined pattern). Algorithm.) And judge the situation based on the process data obtained from multiple sensors. In addition, at the current moment, for example, a red word may be used to display an alarm that a warning has continued to occur, and for example, a black word may be used to display an alarm that the confirmation of the warning has ended.

In addition, if the operator selects any item of the list display in the area R12, the display screens DP5a to DP5d are displayed by the guidance display function 50. The details of the display function and display screen will be described later (see Figure 10 to Figure 13).

According to the areas R11 and R12 in the display screen DP1, the system 30 has the ability to display major abnormalities that may stop the factory 1 and warnings that affect the operating efficiency of the factory 1 in different forms at the same time in different areas. The function. Therefore, the operator can easily recognize both the major abnormality that has the possibility of stopping the factory 1 and the warning that affects the operation efficiency. In addition, it is configured to display whether or not such an abnormality has occurred for a major abnormality that has the possibility of stopping the factory 1, on the other hand, for a warning that affects the operation efficiency, the occurrence history of the warning is displayed. Therefore, the operator can easily recognize whether a major abnormality has occurred currently by viewing the area R11. In addition, it is possible to easily recognize by observing the region R12 whether a warning that affects the operating efficiency has occurred multiple times. Regarding warnings that have an impact on operating efficiency, the time information indicating the occurrence time of the warning and the information indicating the content of the warning are displayed in the order of the occurrence time, so that it is easy to grasp the warning that affects the operating efficiency The frequency of occurrence and the content of various warnings (including abnormalities that occur in components other than the boiler) that affect operating efficiency. In addition, it is not necessary to display the history of warnings affecting the operation efficiency of the factory 1 and the history of a major abnormality that may stop the factory 1 in the area R11. Generally, in order to make factories including factory 1 operate accurately, the operator must monitor a large number of phenomena and parameters. Therefore, it is better to display information efficiently and quickly so as to convey information of high importance to the operator, rather than convey information of low importance. By being configured not to display information of low importance, the operator can easily recognize whether a major abnormality has occurred currently by observing the area R11.

An area R13 is provided in the space between the left central area R11 and the area R12 of the display screen DP1. In the area R13, a plurality of components constituting the plant 1 are displayed as "equipment•component type" information. In addition, it displays the component that may have a warning that may affect the operating efficiency in a manner different from other components.

Specifically, “factory”, “boiler”, “turbine”, “generator”, and “auxiliary equipment” are displayed as components of factory 1. "Boiler" is equivalent to furnace 2 and other parts that make up the boiler. The "turbine" is equivalent to the components that make up the turbine, such as the turbine 100. "Auxiliary equipment" is equivalent to pump 7 and pump 7a and other parts that are not main parts such as boilers. In addition, components such as "generators" that constitute the factory 1 and are highly likely to cause warnings can be appropriately set as components. In addition, it is constituted to determine the process data that is the cause of the warning that affects the operating efficiency. Based on this, for example, a red background color is used to display the components (for example, "boiler" and "generator") that have been warned at the current point in time, For example, components with no warnings (for example, "factory" and "turbine") are displayed with a green background color, and components with no evaluation items set (for example, "auxiliary equipment") are displayed in gray. Furthermore, it is configured to display the warning that the warning has continued to occur in red in the area R12, and the component corresponding to the warning is displayed in the red background color in the area R13, so that the cause of the warning that affects the operating efficiency can be easily determined.的components.

The operator can easily recognize the components constituting the factory 1 that may have a warning that affects the operating efficiency by observing the area R13. In addition, by observing the area R12 and the area R13, it is possible to identify the components that continue to generate warnings at the current point in time even though multiple warnings have occurred in the area R12. In addition, even an operator of a component that cannot predict that a warning that affects the operating efficiency may have occurred based on the region R12 alone can recognize such a component by observing the region R13.

In the lower right area R15 of the display screen DP1, an abnormal occurrence history is displayed in a state in which the data obtained by the sensor shows the abnormal value in a state in which each sensor is arranged. Specifically, the number of abnormalities determined by the DCS 20 within a predetermined period of time, for example, within the past 24 hours, is shown as the "DCS alarm total" information, which is a plato that is totaled for each sensor and arranged in descending order. In addition, "alarm 1", "alarm 2", etc. in FIG. 6 may be configured to display identification information of specific sensors. For example, the identification information of an AE sensor installed at a specific location can be displayed as alarm 1. In addition, the name of the item detected by a specific sensor can also be displayed as alarm 1. For example, it is possible to display information identifying the make-up water flow rate u1 as alarm 1.

The DCS 20 is configured to compare the process data obtained from a single sensor with a predetermined threshold, and when the process data shows an abnormal value exceeding the threshold, it is determined that an abnormality has occurred. In addition, the DCS20 is not configured to determine whether there is an abnormality according to a predetermined algorithm and process data obtained from a plurality of sensors.

The operator can recognize the items with a high risk of developing into a bad condition due to the high frequency of abnormalities through the observation area R15.

In addition, the operator can estimate information related to the cause of the abnormal operation efficiency by comparing the "latest alarm information" displayed in the area R12 or the information displayed in the area R11 with the "DCS alarm total" displayed in the area R15 . For example, when "burst" is displayed in region R1, if a predetermined sensor that is installed in the boiler in region R15 and affects the burst shows an abnormality multiple times, it can be presumed that an abnormality has occurred in the vicinity of the sensor. The abnormality that became the cause of the burst. In addition, when multiple warnings of "SH stored heat" have occurred in the region R12, if a predetermined sensor installed in the furnace in the region R15 that affects the operating efficiency shows a plurality of abnormalities, it can be presumed that An abnormality that caused the decrease in operating efficiency occurred in the vicinity of the sensor.

Information indicating the actual operation of the plant 1 is displayed in the upper right area R14 of the display screen DP1. For example, in the region R14, one or a plurality of trend graphs having indexes important for stable operation as the vertical axis and the horizontal axis as time are displayed. In Figure 6, for example, "boiler efficiency (loss method) [%-LHV]", "generation end efficiency [%]" (an example of "information indicating operating efficiency"), and "generator power [MW]" And the 4 trend graphs of "transmission power [MW]". In addition, the index displayed in the area R14 can be arbitrarily selected by the operator.

Accordingly, in the restricted area of the display screen DP1, when information is displayed for the operation of the factory 1, among the various abnormalities that may occur in the factory 1, there is a possibility of stopping the factory 1 The anomaly is displayed in the area R11 that is separate from the area used to display other anomalies, and the warning about the impact on the operating efficiency of the factory 1 is displayed in the area R12 which is different from the area R11. In addition, with regard to operating efficiency, since the occurrence history is displayed, it is possible to grasp the overall trend of operating efficiency. The operator can easily recognize whether there is an abnormality with the possibility of stopping and whether there is a warning that affects the operating efficiency. In addition, since the data acquired by each sensor shows the number of abnormal values in the area R15, the number of abnormal values is displayed for each sensor, so it is possible to estimate the cause of the abnormality that has the possibility of stopping and the warning that affects the operating efficiency. . In addition, based on the information displayed in the area R14, it is possible to easily identify components that may have a warning that affects the operating efficiency.

The evaluation item display 60 is displayed, for example, below the area R12, and is displayed as a "evaluation item list" as a prompt to confirm a list of a plurality of evaluation items. The evaluation item display 60 is an evaluation item that prompts to confirm the status of the evaluation plant. If the operator selects the evaluation item display 60 on the display screen DP1, the evaluation item display function 52 displays the evaluation item display screen of the evaluation plant status DP6. The details of the display function and display screen will be described later (see Figure 14).

Returning to the flowchart of FIG. 5, the abnormality display function 42 receives an operator's selection for abnormality display (S11). For example, if the operator selects the abnormal display of "burst" displayed in the area R11 on the display screen DP1 shown in FIG. 6, the abnormal details display function 44 displays the details of the abnormality (S12).

Here, an example of the display screen DP2 based on the abnormality detailed content display function 44 will be described using FIG. 7. The display screen DP2 includes areas R20 to R24, a screen update display 72, an abnormality confirmation display 74, and an abnormality history display 76.

In the area R20, "plant operation support system" is displayed as the name of the system 30, and "burst details" is displayed as the current screen state. With the display of the area R20, it is easy to grasp which state of the system the current screen is.

In the right area R21 of the display screen DP2, the positions of the pipes in the entire factory 1 and the positions of the sensors installed in the pipes are displayed (in Fig. 7, they are marked as "circled numbers 1-7", but Image information marked as "(1)～(7)".) in this manual. The positions of the pipes in the entire factory 1 in the area R21 correspond to the factory 1 shown in FIG. 1. In this embodiment, it is shown that the three tubes constituting the superheater 10 of the factory 1 and the three AE sensors ((1), (2), (3)) installed in the three tubes are in the entire factory 1 The positions of the two tubes constituting the economizer 12 and the positions of the two AE sensors ((4), (5)) respectively installed in the two tubes in the entire factory 1 are displayed on the display screen DP2 Area R21. In addition, in this embodiment, the furnace wall tube 6 adjacent to the furnace 2 of the factory 1 and the AE sensors ((6), (7)) installed on the upper and lower parts of the furnace wall tube 6 are in the entire factory The position in 1 is also displayed in the area R21 of the display screen DP2. In addition, these tubes (tube of superheater 10, tube of economizer 12, furnace wall tube 6) and their corresponding AE sensors (1) to (7) are examples. Other tubes and AE sensors It can also be displayed in area R21. In addition, the AE sensor is provided on a metal surface connected to the furnace wall tube or tube, and the metal surface is a metal structure that can propagate without impairing the characteristics of the generated elastic wave.

In addition, it is configured to display the state of the tube detected by the AE sensor in a predetermined manner in the region R21. For example, by obtaining process data from specific AE sensors (such as (1)) in the AE sensors (1) to (7) displayed in the area R21 (by performing signal processing on the AE signal (waveform)) The extracted AE parameter) shows an abnormal value exceeding a predetermined threshold. When it is determined that a burst has occurred in the corresponding tube (the tube of the superheater 10), the abnormal detailed content display function 44 flashes the specific AE sensor ((1)), or make the display color of a specific AE sensor ((1)) different from the display color of other AE sensors ((2) to (7)).

In addition, the abnormal detailed content display function 44 displays the judgment information used when judging the state of the tube using a predetermined algorithm based on the process data related to the plant 1 (the operating data of the plant 1) in the area of the display screen DP2 in chronological order R22. In this embodiment, the process data obtained by the AE sensor ((1)～(7)) (the AE parameters extracted by signal processing on the AE signal (waveform)) is different from the process data obtained by the AE sensor ((1)～(7)) according to a predetermined algorithm. The process data is processed to calculate the probability of burst occurrence (abnormality), and the reliability (reliability) of the process data and algorithm used in the calculation is calculated. The degree of abnormality and the degree of reliability are examples of judgment information. Then, the abnormality detail content display function 44 displays a time chart with both the abnormality degree and the reliability degree as the vertical axis and the last 24 hours as the horizontal axis on the upper part of the area R22 of the display screen DP2. Above the region R22 shown in FIG. 7, the broken line is a time chart of abnormality, and the solid line is a time chart of reliability. The operator can identify the time zone in which the burst may occur by identifying the time charts of both the abnormality and the reliability. For example, in the example shown in FIG. 7, the operator can determine that a burst may have occurred after 11:00 when both the abnormality degree and the reliability degree show high values.

In addition, as shown in FIG. 7, the abnormality detailed content display function 44 displays the time of two parameters α and β (feature data that have an influence on the determination of abnormality or reliability) that are correlated with abnormality and reliability respectively. The figure is shown below area R22. The parameters α and β are also examples of judgment information. In FIG. 7, the one-dot dashed line is a time chart of the parameter α related to the abnormality degree, and the two-dot dashed line is the time chart of the parameter β related to the reliability degree. The operator can make comprehensive judgments related to the occurrence of bursts by recognizing the time chart of abnormality and reliability displayed above the region R22 and the time chart of two parameters α and β arranged below the region R22. The parameters α and β are derived from, for example, a calculation formula for the process up to the calculation of the abnormality and the reliability, so that the accuracy of the abnormality and the reliability can be used for confirmation. In the example shown in FIG. 7, there is only one graph related to the determination information, but multiple graphs can also be displayed.

In addition, the abnormal detailed content display function 44 is configured to combine the detection result of the tube state obtained by the AE sensor and the process data obtained by the AE sensor (by performing signal processing on the AE signal (waveform) and extracting the result). AE parameters) The judgment results of the states of the tubes of different process data are displayed in the same form in the area R23 of the display screen DP2. The abnormal detailed content display function 44 in this embodiment displays the detection results obtained by the AE sensor in the last 24 hours on whether a burst has occurred in the tube in chronological order in a horizontally long bar graph on the upper part of the area R23 ( Shown as "AE Method"). In addition, the abnormal detailed content display function 44 displays the judgment results based on process data and algorithms for the last 24 hours on whether a tube burst has occurred in a horizontally long bar graph below the area R23 (displayed as " logic"). That is, in this embodiment, both the detection result obtained by the AE method and the judgment result obtained by the logic are displayed in the same form as a bar graph in chronological order. In addition, in this embodiment, the time axis displayed in each time chart in the area R22 and the time axis displayed in each bar chart in the area R23 are displayed in conjunction with each other.

In each bar graph, the area indicated by the hatched "horizontal line" indicates the time zone where a burst has occurred and the operator has confirmed the fact, and the area indicated by an exclamation point is indicated by "hollow" The determination (detection) is the time period during which a burst has occurred and the operator has not confirmed the fact. On the other hand, the area indicated by the hatched "upward rightward diagonal" indicates the time zone when it is determined (detected) that no burst has occurred and the operator has not confirmed the fact, and the area "blacked out" indicates that the determination (detection) is The time frame during which no burst has occurred and the operator has confirmed the fact. The operator can recognize the two bar graphs to determine that the possibility of bursting is high in the time zone where the exclamation point is displayed in the "hollow" area (for example, around 14:00, around 8:00, etc.).

In addition, the operator can grasp the specific AE sensor (for example (1)) corresponding to the tube that burst at the current time by displaying the area R21 of the display screen DP2, and can use the display screen DP2 The area R23 is displayed to grasp the time history of the burst. Therefore, the operator can recognize both the region R21 and the region 23 to grasp how much time has passed since the tube corresponding to the specific AE sensor (for example (1)) burst.

In the example shown in this embodiment, the determination results of the AE method and the logic method both show that a burst has occurred at the current time "14:00", whereby the abnormality display function 42 can be displayed in the area of the previous display screen DP1 An abnormal display indicating the occurrence of burst is displayed in R11. At this time, the description 62 of the area R11 of the display screen DP1 may display the content of the occurrence of the burst in each of the determination results of the AE method and the logic method. In addition, the abnormal display based on the abnormal display function 42 is not limited to the case where both the AE method and the logic method indicate the occurrence of a burst, and can be displayed when either one of them indicates the occurrence of a burst. At this time, it is possible to display in the explanatory text 62 of the area R11 of the display screen DP1 which method of the AE method or the logic method is used to determine the occurrence of the burst.

In the area R24 of the display screen DP2, an explanatory text 70 related to "burst" is displayed. The explanatory text 70 in the display screen DP2 may also show the abnormal content in more detail than the explanatory text 62 in the previous display screen DP1. For example, in the case of the occurrence of a burst based on the AE method, the explanatory text 70 can show a specific AE sensor that is the basis for an abnormal display indicating the occurrence of a burst, and includes prompting the operator to confirm the specific AE sensor The content of the data of the device. In this way, by displaying the explanatory text 70 related to the abnormal display on the display screen DP2 showing the details of the abnormal display, the operator can easily grasp the current situation and the subsequent application from a more detailed perspective on the state of the factory 1 than the display screen DP1. Measures taken, etc.

If the operator selects the screen update display 72 on the display screen DP2, the display content of the display screen DP2 is updated. In this way, for example, even if it does not change to a different display such as the display screen DP1, the content of the latest display screen DP2 can be grasped.

If the operator selects the explosion confirmation display 74 on the display screen DP2, the system 30 determines that the operator has confirmed the occurrence of the explosion. When returning to the display screen DP1 shown in FIG. 1 The abnormal burst of the possibility of stopping shows a different appearance. In this case, for example, the character "burst" may not be displayed on the display screen DP1, and the emphasis display of "burst" may be suppressed. In addition, it is also possible to stop emitting effect sounds or sounds such as warning sounds at the same time.

In addition, if the operator selects the burst history display 76 on the display screen DP2, the abnormal history display function 48 displays the display screen DP4. The details of the display function and display screen will be described later (see Figure 9).

Returning to the flowchart of FIG. 5, the abnormality details display function 44 receives the abnormal state of the tube corresponding to the specific AE sensor ((1)) showing the abnormal value in the area R21 of the display screen DP2 The displayed selection comes from the operator (S13). For example, if the operator selects the display of a specific AE sensor (such as (1)) among the AE sensors ((1) to (7)) displayed in the area R21 of the display screen DP2, then The sensor data detailed content display function 46 displays the data of the specific AE sensor (for example (1)) that is the basis for the abnormal state indicating the occurrence of the burst (S14).

Here, an example of the display screen DP3 based on the sensor data detailed content display function 46 will be described using FIG. 8. The display screen DP3 includes areas R30 to R34.

In the area R30, as the current screen state, "burst details" is displayed. By displaying the area R30, it is easy to grasp which state the current screen is in.

The upper area R31 of the display screen DP3 receives input of date and time, sensor number, and adjustment of the Y axis. In addition, in the lower area R32 of the display screen DP3, by the sensor data detail display function 46, specific AE sensors (e.g. (1 ))data of. In the example shown in Figure 8, the process data (AE parameters extracted by signal processing on the AE signal (waveform)) detected by the specific AE sensor ((1)) is taken as the vertical axis and the last 24 hours The time chart as the horizontal axis is displayed in the area R32 of the display screen DP3. If a burst occurs, a larger energy (elastic wave) than normal operation is released. Therefore, for example, the operator can recognize the time series diagram displayed in the area R32 of the display screen DP3 to determine that the maximum value of the AE parameter has occurred. The time zone burst. In addition, the operator can display or change the date and time of the target graph or the sensor number in the area R32 by inputting the date and time of the area R31, the sensor number and adjusting the Y axis, or adjust the specific sensor The scale of the Y-axis of the data (scaling). In this way, the operator can easily and quickly analyze the data of each sensor.

In addition, in the space between the area R30 and the area R31 of the display screen DP3, an explanatory text 80 related to "burst" is displayed. The explanatory text 80 in the display screen DP3 may be a person who shows the abnormal content in more detail than the explanatory text 70 in the previous display screen DP2. For example, the explanatory text 80 may display the tendency, analysis, and coping method of the data of the specific AE sensor that is the basis for the abnormal display indicating the occurrence of a burst. In this way, by displaying the explanatory text 80 related to the abnormal display on the display screen DP3 displaying the data of the sensor that is the basis of the abnormal state, the operator can have a more detailed view on the state of the factory 1 than the display screen DP2 It is easy to grasp the current situation and the measures to be taken next.

In addition, the determination information used when determining the state of the tube using a predetermined algorithm can be displayed in the region R22 of the display screen DP2 in chronological order. Therefore, the operator who has recognized the display screen DP2 of the system 30 can not only grasp the position of the tube and the AE sensor in the entire factory 1, but also grasp the position in different ways (both the AE sensor and the algorithm). The state of the tube that is judged or detected. That is, the operator can efficiently grasp the important information required for monitoring the tube only by recognizing a single screen (display screen DP2), and therefore can make comprehensive judgments. For example, (i) When both the AE sensor (area R21) and the algorithm (area R22) detect and determine the occurrence of a burst, the operator judges that a burst has occurred in a specific pipe in the factory 1. The possibility is high. By selecting the AE sensor that detected the burst occurrence in the area R21, the time history of the sound pressure level of the AE sensor is confirmed in the area R32 of the third screen DP3 (Figure 8), thereby It can be determined in which time zone the burst occurred. Also, (ii) when the occurrence of a burst is detected in the AE sensor (area R21), but the occurrence of a burst is not determined in the algorithm (area R22), the operator judges that the occurrence of the explosion is in the factory 1 A burst may have occurred in a tube. By selecting the AE sensor that detected the burst in the area R21, confirm the sound pressure level of the AE sensor in the area R32 of the third screen DP3 (Figure 8). And confirm the determination information (abnormality and reliability) in the area R22, so that the reliability of the burst can be determined. In addition, (iii) Although the occurrence of a burst is not detected in the AE sensor (area R21), if the occurrence of a burst is determined in the algorithm (area R22), the operator judges that it is in the factory 1 A burst may have occurred in any tube, and the burst can be determined based on the determination information in the area R22 (in addition to the abnormality and reliability, two parameters α and β that are related to the abnormality and the reliability, respectively) Authenticity. Therefore, the present system 30 can contribute to the stable operation of the factory 1.

In addition, in the system 30, both the detection result of the tube state obtained by the AE sensor and the determination result of the tube state based on a predetermined algorithm can be displayed in the same format (bar graph). Area R23 of the screen DP2. Therefore, the operator can recognize and grasp the tube state judgment (detection) results obtained by different methods in the same form, and can make comprehensive judgments.

In addition, in the system 30, the detection information detected by the selected specific sensor (for example (1)) among the AE sensors displayed in the area R21 of the display screen DP2 can be displayed in chronological order in the slave with The area R21 and the like of the display screen DP2 transition to the area R32 of the display screen DP3. Therefore, there are advantages in that the detection information can be enlarged and displayed in the area R32 of the display screen DP3 different from the display screen DP2 having the area R21 and the like, and the time history of the detection information can be grasped in detail.
