First, the configuration of the factory 1 to which the present embodiment is intended will be described with reference to FIG. 1 . Plant 1 is, for example, a power plant (incineration plant) including a circulating fluidized bed (Circulating Fluidized Bed type) boiler, and is equipped with a boiler that generates steam by burning fuel while circulating a circulating material such as silica sand flowing at a high temperature . As the fuel for the factory 1, in addition to fossil fuels such as coal, for example, non-fossil fuels (woody biomass, waste tires, waste plastics, sludge, etc.) can be used. The steam produced in the plant 1 is used to drive the turbine 100 . In addition, the factory targeted in this embodiment is not limited to a power plant including a boiler or an incineration plant, as long as it is a factory that can obtain process data, for example, a chemical plant, a wastewater treatment plant, and the like.

工廠1構成為，使燃料在燃燒爐2內燃燒，藉由作為固氣分離裝置發揮作用之旋風器3，從廢氣分離循環材料，使被分離之循環材料返回燃燒爐2內並使其循環。將被分離之循環材料經由與旋風器3的下方連接之循環材料回收管4返送至燃燒爐2的下部。另外，循環材料回收管4的下部和燃燒爐2的下部係經由流路被縮小之環封部4a而連接。藉此，成為在循環材料回收管4的下部儲存有規定量的循環材料之狀態。藉由旋風器3去除了循環材料之排放氣體係經由排放氣體流路3a供給到後部煙道5。The plant 1 is configured such that fuel is combusted in a combustion furnace 2 , a cyclone 3 functioning as a solid-gas separation device separates a circulating material from the exhaust gas, and the separated circulating material is returned to the combustion furnace 2 and circulated. The separated circulating material is returned to the lower part of the combustion furnace 2 via the circulating material recovery pipe 4 connected to the lower part of the cyclone 3 . In addition, the lower part of the circulating material recovery pipe 4 and the lower part of the combustion furnace 2 are connected via the ring seal part 4a in which the flow path is reduced. Thereby, a predetermined amount of circulating material is stored in the lower part of the circulating material recovery pipe 4 . The exhaust gas system from which the circulating material has been removed by the cyclone 3 is supplied to the rear flue 5 through the exhaust gas flow path 3a.

鍋爐係具備用於使燃料燃燒之燃燒爐2和用於使用藉由燃燒而獲得之熱量產生水蒸汽等之熱交換器。在燃燒爐2的中間部設置有供給燃料之燃料供給口2a，在燃燒爐2的上部設置有排出燃燒氣體之氣體出口2b。從未圖示之燃料供給裝置供給到燃燒爐2之燃料係經由燃料供給口2a供給到燃燒爐2的內部。又，在燃燒爐2的爐壁上設置有用於加熱鍋爐供水之爐壁管6。流過爐壁管6之鍋爐供水係藉由在燃燒爐2中的燃燒而被加熱。The boiler is provided with a combustion furnace 2 for burning fuel, and a heat exchanger for generating steam or the like using the heat obtained by the combustion. A fuel supply port 2 a for supplying fuel is provided in the middle portion of the combustion furnace 2 , and a gas outlet 2 b for discharging combustion gas is provided in the upper portion of the combustion furnace 2 . The fuel supplied to the combustion furnace 2 from a fuel supply device (not shown) is supplied to the inside of the combustion furnace 2 through the fuel supply port 2a. Moreover, on the furnace wall of the combustion furnace 2, a furnace wall pipe 6 for heating the boiler water supply is provided. The boiler water supply flowing through the furnace wall tubes 6 is heated by combustion in the combustion furnace 2 .

在燃燒爐2內，藉由從下部的供氣管線2c導入之燃燒・流動用空氣而包含從燃料供給口2a供給之燃料之固態物流動，燃料一邊流動一邊在例如約800~900℃下燃燒。燃燒爐2中產生之燃燒氣體與循環材料一起被導入到旋風器3中。旋風器3藉由離心分離作用而分離循環材料和氣體，使所分離之循環材料經由循環材料回收管4而返回到燃燒爐2，並且將去除了循環材料之燃燒氣體從排放氣體流路3a向後部煙道5送出。In the combustion furnace 2, solid matter including the fuel supplied from the fuel supply port 2a flows by the combustion/flow air introduced from the lower air supply line 2c, and the fuel is burned at, for example, about 800 to 900°C while flowing. . The combustion gas generated in the combustion 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, the separated circulating material is returned to the combustion furnace 2 through the circulating material recovery pipe 4, and the combustion gas from which the circulating material has been removed is transferred from the exhaust gas flow path 3a to the combustion furnace 2. The rear flue 5 is sent out.

在燃燒爐2中，被稱作爐內床料(bed material)之循環材料的一部分停留於底部。該床料中有時包含不適合於循環流動之具有粗粒徑之床料或排燃物夾雜物，有時因該等不適合作為循環材料之床料而產生流動不良。因此，為了抑制流動不良，在燃燒爐2中，爐內床料從底部的排出口2d連續地或斷續地被排出到外部。被排出之床料在未圖示之循環管線上去除金屬或粗大粒徑等不適物之後，再度供給到燃燒爐2或者直接被廢棄。燃燒爐2的循環材料在由燃燒爐2、旋風器3及循環材料回收管4構成之循環體系內循環。In the combustion furnace 2, a part of the circulating material called bed material stays at the bottom. The bed material sometimes contains bed material with coarse particle size or inclusions of exhaust gas that are not suitable for circulating flow, and sometimes poor flow occurs due to the bed material that is not suitable for circulating flow. Therefore, in order to suppress poor flow, in the combustion 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 combustion furnace 2 again or discarded as it is after removing undesired substances such as metals and coarse particles on a circulation line (not shown). The circulating material of the combustion furnace 2 circulates in the circulation system composed of the combustion furnace 2 , the cyclone 3 and the circulating material recovery pipe 4 .

後部煙道5具有使從旋風器3排出之氣體流向後段之流路。後部煙道5具有產生過熱蒸汽之過熱器10和對鍋爐供水進行預熱之節煤器12來作為回收排放氣體的熱量之排熱回收部。流過後部煙道5之排放氣體係與在過熱器10及節煤器12中流通之蒸汽或鍋爐供水進行熱交換而被冷却。又，具有儲存通過了節煤器12之鍋爐供水之汽鼓8，汽鼓8還連接於燃燒爐壁6。The rear flue 5 has a flow path through which the gas discharged from the cyclone 3 flows to the rear stage. The rear flue 5 has a superheater 10 for generating superheated steam and an economizer 12 for preheating the boiler feed water as a heat exhaust recovery part for recovering the heat of the exhaust gas. The exhaust gas system flowing through the rear flue 5 is cooled by heat exchange with the steam or boiler water flowing through the superheater 10 and the economizer 12 . Also, there is a steam drum 8 for storing the boiler feed water which has passed through the economizer 12 , and the steam drum 8 is also connected to the combustion furnace wall 6 .

節煤器12係將排放氣體的熱量傳遞給鍋爐供水而對鍋爐供水進行預熱者。節煤器12藉由管21而與泵7連接，另一方面，藉由管22而與汽鼓8連接。從泵7經由管21供給到節煤器12並藉由節煤器12進行了預熱之鍋爐供水係經由管22供給到汽鼓8。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 via the pipe 21 , and is connected to the steam drum 8 via the 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 .

汽鼓8上連接有降水管8a及爐壁管6。汽鼓8內的鍋爐供水係在降水管8a中下降，並在燃燒爐2的下部側導入到爐壁管6而朝向汽鼓8流通。爐壁管6內的鍋爐供水係藉由在燃燒爐2內產生之燃燒熱而被加熱，並在汽鼓8內蒸發而成為蒸汽。The steam drum 8 is connected with a dewatering pipe 8a and a furnace wall pipe 6 . The boiler water supply system in the steam drum 8 descends in the downpipe 8 a, is introduced into the furnace wall tube 6 on the lower side of the combustion furnace 2, and flows toward the steam drum 8. The boiler water supply system in the furnace wall tube 6 is heated by the combustion heat generated in the combustion furnace 2 and evaporated in the steam drum 8 to become steam.

汽鼓8上連接有排出內部的蒸汽之飽和蒸汽8b。飽和蒸汽管8b將汽鼓8和過熱器10進行連接。汽鼓8內的蒸汽係經由飽和蒸汽管8b供給到過熱器10。過熱器10係使用排放氣體的熱量對蒸汽進行過熱而產生過熱蒸汽者。過熱蒸汽係通過管10a而供給到工廠1外的渦輪機100，並利用於發電。The steam drum 8 is connected to the saturated steam 8b which discharges the steam inside. The saturated steam pipe 8b connects the steam drum 8 and the superheater 10. The steam system in the steam drum 8 is supplied to the superheater 10 via the saturated steam pipe 8b. The superheater 10 generates superheated steam by superheating the steam using the heat of the exhaust gas. The superheated steam is supplied to the turbine 100 outside the factory 1 through the pipe 10a, and is used for power generation.

從渦輪機100排出之蒸汽的壓力和溫度低於從過熱器10排出之蒸汽的壓力和溫度。雖然不受特別限定，但供給到渦輪機100之蒸汽的壓力為約10~17MPa左右，溫度為約530~570℃左右。The pressure and temperature of the steam exiting the turbine 100 are lower than the pressure and temperature of the steam exiting the superheater 10 . Although not particularly limited, the pressure of the steam supplied to the turbine 100 is about 10 to 17 MPa, and the temperature is about 530 to 570°C.

在渦輪機100的下游設置有冷凝器102。從渦輪機100排出之蒸汽係供給到冷凝器102，並在冷凝器102中凝結而恢復為飽和水之後供給到泵7。渦輪機100上連接有將藉由渦輪機100的旋轉而獲得之動能轉換為電能之發電機(generator)。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 and returned to saturated water, and then supplied to the pump 7 . A generator is connected to the turbine 100 for converting kinetic energy obtained by the rotation of the turbine 100 into electrical energy.

泵7a供給補給水，以使冷凝器102的水位保持為恆定。在圖1中，示出由泵7a補充之補給水流量u1 (「流程資料」的一例)。The pump 7a supplies makeup water to keep the water level of the condenser 102 constant. In FIG. 1, the make-up water flow rate u1 (an example of "flow data") supplemented by the pump 7a is shown.

在本實施方式中處理之流程資料(與工廠1的運轉有關之資料)可以為與工廠1有關之任意資料，例如可以為由感測器測定工廠1的狀態之資料(「流程資料」的一例)，更具體而言，可以包括工廠1的溫度、壓力及流量等測定值。在圖1中示出從泵7供給到節煤器12之鍋爐供水流量u2(「流程資料」的一例)。另外，在圖1中示出從過熱器10供給到渦輪機100之鍋爐出口蒸汽流量u3(「流程資料」的一例)，且示出從汽鼓8供給到過熱器10之飽和蒸汽流量u4(「流程資料」的一例)。另外，補給水流量u1可以被控制為跟隨飽和蒸汽流量u4。又，亦可以一邊監視鍋爐出口蒸汽流量u3(或過熱蒸汽流量)和汽鼓8的液面位準的雙方，一邊將鍋爐供水流量u2控制為跟隨調整。The process data (data related to the operation of the factory 1) handled in this embodiment may be any data related to the factory 1, for example, data for measuring the state of the factory 1 by a sensor (an example of "process data") ), more specifically, the measured values of the temperature, pressure, and flow rate of the plant 1 can be included. FIG. 1 shows the boiler water supply flow rate u2 (an example of "flow data") supplied from the pump 7 to the economizer 12 . 1 shows the boiler outlet steam flow u3 supplied from the superheater 10 to the turbine 100 (an example of "flow data"), and shows the saturated steam flow u4 supplied from the steam drum 8 to the superheater 10 (" an example of "Process Data"). Additionally, the makeup water flow u1 may be controlled to follow the saturated steam flow u4. In addition, the boiler feed water flow rate u2 may be controlled to follow adjustment 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 .

當在構成工廠1之管系統中產生破孔時，補給水流量u1上升或者鍋爐供水流量u2與鍋爐出口蒸汽流量u3的流量差增大。DCS(Distributed Control System：分散控制系統，圖2)20從工廠1接收補給水流量u1、鍋爐供水流量u2、鍋爐出口蒸汽流量u3及飽和蒸汽流量u4等工廠1的流程資料，並監視工廠1的運轉狀況，從而監視工廠1是否發生了異常。如後述，監視裝置40(圖2)依據按異常的每個種類設定之警報判定邏輯來評量流程資料，當發生了異常時，發出警報。When a hole is generated in the pipe system constituting the plant 1, the make-up water flow rate u1 increases or the flow rate difference between the boiler feed water flow rate u2 and the boiler outlet steam flow rate u3 increases. DCS (Distributed Control System: Distributed Control System, Fig. 2) 20 receives the flow data of Factory 1, such as 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, from Factory 1, and monitors the flow rate of Factory 1. The operation status is monitored to monitor whether an abnormality has occurred in Plant 1. As will be described later, the monitoring device 40 ( FIG. 2 ) evaluates the flow data according to an alarm determination logic set for each type of abnormality, and issues an alarm when an abnormality occurs.

另外，作為流程資料，示出了補給水流量u1、鍋爐供水流量u2、鍋爐出口蒸汽流量u3及飽和蒸汽流量u4，但與工廠1有關之流程資料亦可以為其他資料或依據複數個流程資料計算之資料。與工廠1有關之流程資料可以為溫度、壓力等其他資料，亦可以為從感測器等取得之未經計算處理之資料。In addition, as the process data, the make-up water flow u1, the boiler water supply flow u2, the boiler outlet steam flow u3 and the saturated steam flow u4 are shown, but the process data related to Plant 1 can also be calculated from other data or based on multiple process data information. The process data related to Factory 1 can be other data such as temperature, pressure, etc., or the data obtained from sensors and the like without calculation processing.

接著，使用圖2及圖3對本實施方式之系統30進行說明。圖2為表示本實施方式之系統30的功能方塊之圖。圖3為表示本實施方式之系統30的物理構成之圖。Next, the system 30 of the present embodiment will be described with reference to FIGS. 2 and 3 . FIG. 2 is a diagram showing functional blocks of the system 30 of the present embodiment. FIG. 3 is a diagram showing the physical configuration of the system 30 according to the present embodiment.

DCS20係用於控制工廠1之分散控制系統，如圖2所示，從設置於工廠1之感測器等取得流程資料，並將用於依據該流程資料控制工廠1之控制訊號供給到工廠1。DCS20 is a distributed control system used to control Factory 1. As shown in Figure 2, it obtains process data from sensors installed in Factory 1, etc., and supplies control signals to Factory 1 for controlling Factory 1 based on the process data. .

系統30具備顯示裝置32及監視裝置40。監視裝置40具備控制部31及記憶部33。作為功能構成，控制部31例如具備取得部311、計算部312、生成部313、受理部314及顯示控制部315。記憶部33儲存各種資料，例如儲存流程資訊DB33A、警報資訊DB33B及發生履歷資訊DB33C。The system 30 includes a display device 32 and a monitoring device 40 . The monitoring device 40 includes a control unit 31 and a memory unit 33 . As a functional configuration, the control unit 31 includes, for example, an acquisition unit 311 , a calculation unit 312 , a generation unit 313 , a reception unit 314 , and a display control unit 315 . The memory unit 33 stores various data, for example, a process information DB 33A, an alarm information DB 33B, and an occurrence history information DB 33C.

取得部311例如從DCS20取得流程資料。取得部311在工廠1的運轉中從DCS20依序取得流程資料。所取得之流程資料作為與工廠1的流程有關之資訊(以下，亦稱為「流程資訊」)儲存於流程資訊DB33A中。另外，工廠1只要至少一部分在運轉，則處於「運轉中」。又，工廠1的運轉期間係至少一部分在運轉之期間，係除維護等事先計劃之停止期間以外的期間。The acquisition unit 311 acquires, for example, the flow data from the DCS 20 . The acquisition unit 311 sequentially acquires the flow data from the DCS 20 during the operation of the factory 1 . The acquired process data is stored in the process information DB 33A as information related to the process of the factory 1 (hereinafter, also referred to as "process information"). In addition, the factory 1 is "in operation" as long as at least a part of it is in operation. In addition, the operation period of the factory 1 is a period during which at least a part of the operation period is in operation, and is a period other than a previously planned stop period such as maintenance.

又，取得部311從DCS20取得警報資訊。取得部311在工廠1的運轉中每次發出警報(「發生」的一例)時從DCS20取得警報資訊。警報資訊係表示工廠1中發生之警報者，且係關於所發生之異常的警報(警告)的資訊。警報資訊包括警報項目(該警報的種類)、警報發生日期時間(該警報發生之日期時間)、警報等級(係該警報的等級(重要度)等，例如被分類為嚴重警報、中等警報、輕度警報等)及與該警報相關之流程資料的值(例如，判定為異常之補給水流量u1、鍋爐供水流量u2的值)等。Moreover, the acquisition part 311 acquires alarm information from DCS20. The acquisition unit 311 acquires alarm information from the DCS 20 every time an alarm (an example of "occurrence") is issued during the operation of the factory 1 . The alarm information indicates an alarm that has occurred in the factory 1, and is information about an alarm (warning) of an abnormality that has occurred. The alarm information includes the alarm item (the type of the alarm), the date and time of the alarm occurrence (the date and time of the alarm occurrence), the alarm level (the level (importance) of the alarm, etc., for example, it is classified into a serious alarm, a medium alarm, a light alarm, etc. alarm, etc.) and the value of the process data related to the alarm (for example, the value of the make-up water flow rate u1 and the boiler water supply flow rate u2 determined to be abnormal), and the like.

在DCS20中判定工廠1有無發生異常等，當判定為發生了異常時生成警報資訊。例如，當流程資料中所包含之某些值超出規定的閾值時或傾向發生了規定的變化時，DCS20判定為發生了異常。更具體而言，DCS20可以依據警報判定邏輯來評量規定的流程資料，並判定有無發生爆裂(如鍋爐爐管洩漏那樣，構成鍋爐之爐管及管道等金屬材料發生損傷而破孔，從而內部的蒸汽洩漏到外部之狀態。包括將來發生爆裂之可能性高的狀態。以下相同)之類的在工廠1有可能發生之異常。由DCS20生成之警報資訊亦特別稱為「DCS警報資訊」。同樣地，在系統30中，亦可以依據由取得部311取得之流程資料來判定有無發生工廠1的異常等，從而判定為發生了異常。將此時生成之警報資訊亦特別稱為「系統警報資訊」。以下，將DCS警報資訊及系統警報資訊統稱為「警報資訊」。警報資訊儲存於警報資訊DB33B中。The DCS 20 determines whether or not an abnormality has occurred in the plant 1, and generates alarm information when it is determined that an abnormality has occurred. For example, DCS 20 determines that an abnormality has occurred when some values included in the process data exceed a predetermined threshold or when a predetermined change occurs in the trend. More specifically, DCS20 can evaluate the specified process data according to the alarm judgment logic, and determine whether there is a burst (such as a boiler furnace tube leakage, the furnace tubes and pipes that make up the boiler are damaged and the metal materials are broken, so that the internal The state in which the steam leaks to the outside. Including a state with a high possibility of explosion in the future. The same applies to the following) and other abnormalities that may occur in Factory 1. Alert messages generated by DCS 20 are also specifically referred to as "DCS alert messages". Similarly, in the system 30, it is possible to determine whether or not an abnormality of the factory 1 has occurred or the like based on the flow data acquired by the acquisition unit 311, thereby determining that an abnormality has occurred. The alarm information generated at this time is also specifically referred to as "system alarm information". Hereinafter, DCS alarm information and system alarm information are collectively referred to as "alarm information". The alarm information is stored in the alarm information DB33B.

計算部312依據儲存於警報資訊DB33B中之警報資訊，按表示警報的種類之每個警報種類計算第1期間的發生頻率。所計算之每個警報種類的發生頻率係表示在過去的一定期間內工廠1中發生之該警報種類的警報頻率之指標。第1期間係工廠1的運轉期間內的一部分期間，例如為24小時。第1期間可以為事先設定之期間，亦可以為能夠適當變更之期間。如此，藉由第1期間為工廠1的運轉期間的一部分期間，能夠關注從工廠1的運轉期間抽出之期間而顯示每個警報種類的發生頻率，例如能夠輕易地掌握在特定的時間段發生之警報種類的發生頻率。The calculation part 312 calculates the frequency of occurrence of the first period for each alarm type indicating the type of alarm based on the alarm information stored in the alarm information DB 33B. The calculated occurrence frequency of each alarm type is an index indicating the alarm frequency of the alarm type that occurred in the plant 1 in the past certain period. The first period is a part of the operating period of the factory 1, and is, for example, 24 hours. The first period may be a period set in advance or a period that can be appropriately changed. In this way, since the first period is a part of the operating period of the factory 1, the period extracted from the operating period of the factory 1 can be noted and the frequency of occurrence of each alarm type can be displayed. The frequency of occurrence of the alarm type.

發生頻率例如為第1期間內的發生次數。藉此，能夠輕易地掌握第1期間內的每個警報種類的發生次數。The frequency of occurrence is, for example, the number of occurrences in the first period. Thereby, the number of occurrences of each alarm type in the first period can be easily grasped.

另外，發生頻率並不限定於第1期間的發生次數，亦可以為第1期間內的發生比例(例如，該警報種類的發生次數相對於所有警報種類在第1期間內的平均發生次數所佔據之比例)、發生度數(例如，將所有警報種類在第1期間內的平均發生次數設為基準值｛例如「1」｝時該警報種類的度數)等。In addition, the frequency of occurrence is not limited to the number of occurrences in the first period, but may also be the proportion of occurrences in the first period (for example, the number of occurrences of the alarm type relative to the average number of occurrences of all types of alarms in the first period) ratio), the frequency of occurrence (for example, the frequency of the alarm type when the average number of occurrences of all alarm types in the first period is set as the reference value {for example, "1"}).

計算部312例如在事先設定之任意時間點(例如，發生了警報之時間點、每1秒、每1分鐘、每1小時等)按每個警報種類計算第1期間的發生頻率。用於計算發生頻率之警報種類係利用任意方法來分類。警報的種類例如可以按用於測定工廠1的狀態之每個感測器來分類。在該情況下，警報的種類例如可以包括與補給水流量有關之警報、與鍋爐供水流量有關之警報、與鍋爐出口蒸汽流量有關之警報、與飽和蒸汽流量有關之警報等種類。The calculation unit 312 calculates the frequency of occurrence of the first period for each alarm type, for example, at an arbitrary time point set in advance (for example, the time point when an alarm occurs, every second, every minute, every hour, etc.). The types of alarms used to calculate the frequency of occurrence are classified by an arbitrary method. The types of alarms can be classified, for example, for each sensor for measuring the state of the plant 1 . In this case, the types of alarms may include, for example, alarms related to makeup water flow, alarms related to boiler feed water flow, alarms related to boiler outlet steam flow, and alarms related to saturated steam flow.

又，計算部312依據DCS警報資訊來計算每個警報種類在第1期間的發生頻率。亦即，計算部312所計算之每個警報種類在第1期間的發生頻率由DCS20的警報資訊計算。Further, the calculation unit 312 calculates the frequency of occurrence of each alarm type in the first period based on the DCS alarm information. That is, the occurrence frequency of each alarm type calculated by the calculation unit 312 in the first period is calculated from the alarm information of the DCS 20 .

History information is generated. The generated occurrence history information of the alarm type is information related to the occurrence history of the alarm of the alarm type that occurred in the factory 1 in the past certain period. The second period is a period included in the first period, and is, for example, the same 24 hours as the first period. The second period may be a period set in advance or a period that can be appropriately changed. In addition, the second period may be a period shorter than the first period, for example, 12 hours, 8 hours, or 6 hours.

儀表板顯示畫面DP1在每個規定時間顯示與工廠1的運轉有關之最新的各種指標。儀表板顯示畫面DP1例如顯示基於與工廠1的運轉有關之各種指標的趨勢圖等。又，儀表板顯示畫面DP1例如顯示表示具有工廠1的停止可能性之異常發生或可能性之異常顯示和表示與工廠1有關之流程資料成為規定狀態時的警告發生或可能性之警告顯示。又，儀表板顯示畫面DP1例如顯示警報的件數或發生時刻。另外，儀表板顯示畫面DP1按每個警報種類顯示第1期間內的發生頻率。The instrument panel display screen DP1 displays the latest various indicators related to the operation of the factory 1 every predetermined time. The instrument panel display screen DP1 displays, for example, a trend graph based on various indexes related to the operation of the factory 1, and the like. In addition, the instrument panel display screen DP1 displays, for example, an abnormality display indicating the occurrence or possibility of an abnormality having the possibility of stopping the plant 1, and a warning display indicating the occurrence or possibility of a warning when the process data related to the plant 1 becomes a predetermined state. Moreover, the instrument panel display screen DP1 displays, for example, the number of alarms or the time of occurrence. In addition, the instrument panel display screen DP1 displays the frequency of occurrence in the first period for each alarm type.

發生履歷顯示畫面DP2關於在儀表板顯示畫面DP1上選擇之警報種類而顯示第2期間內的發生履歷。又，在發生履歷顯示畫面DP2上，能夠選擇與在儀表板顯示畫面DP1上選擇之警報種類相關之相關事件。發生履歷顯示畫面DP2亦能夠關於所選擇之相關事件而顯示第2期間內的發生履歷。The occurrence history display screen DP2 displays the occurrence history in the second period with respect to the alarm type selected on the instrument panel display screen DP1. In addition, on the occurrence history display screen DP2, it is possible to select a related event related to the alarm type selected on the instrument panel display screen DP1. The occurrence history display screen DP2 can also display the occurrence history in the second period with respect to the selected related event.

接著，使用圖5對儀表板顯示畫面DP1的一例進行說明。儀表板(dashboard)顯示畫面DP1包括區域R10~R13。另外，圖5所示之例子為儀表板顯示畫面DP1的一部分，實際儀表板顯示畫面DP1還包括區域R10~R13以外的區域。Next, an example of the instrument panel display screen DP1 will be described using FIG. 5 . The dashboard display screen DP1 includes regions R10 to R13. In addition, the example shown in FIG. 5 is a part of the instrument panel display screen DP1, and the actual instrument panel display screen DP1 also includes areas other than the areas R10 to R13.

在區域R10中，作為當前畫面的狀態，顯示為「儀表板」。藉由區域R10的顯示，能夠輕易地掌握當前的畫面為哪種狀態。In the area R10, "Dashboard" is displayed as the state of the current screen. By displaying the area R10, it is possible to easily grasp what state the current screen is in.

在儀表板顯示畫面DP1的區域R11中顯示有表示與工廠有關之流程資料成為規定狀態時的警告發生之警告顯示作為「最新警報資訊」。警告顯示係顯示對工廠1的運行效率產生影響之流程資料的規定狀態者，例如並非像爆裂那樣具有工廠1停止之可能性，但會使工廠1的運行效率下降。在區域R11中，警告顯示的發生履歷係以將表示其發生時間之時間資訊和表示其內容之資訊按發生時間的順序排列之狀態進行顯示。例如，在區域R11的前頭，建立對應關係而顯示有「YYYY/MM/DD hh：mm：ss」這一時間資訊和「警報A」這一表示警告內容之資訊。藉由顯示於該區域R11之資訊，工廠1的操作者能夠識別關於警報A之警告於YYYY年MM月DD日hh點mm分ss秒發生。同樣地，工廠1的操作者能夠識別表示對工廠1的運行效率產生影響之其他流程資料的規定狀態的發生時間之時間資訊和表示其內容之資訊的履歷。In the area R11 of the instrument panel 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 "latest warning information". The warning display shows the predetermined state of the process data that affects the operation efficiency of the factory 1. For example, there is no possibility that the factory 1 will stop like a burst, but the operation efficiency of the factory 1 will decrease. In the area R11, the occurrence history of the warning display is displayed in a state in which time information indicating the occurrence time and information indicating the content thereof are arranged in the order of occurrence time. For example, at the head of the area R11, the time information "YYYY/MM/DD hh:mm:ss" and the information indicating the content of the warning are displayed as "YYYY/MM/DD hh:mm:ss" in correspondence. With the information displayed in this area R11, the operator of the factory 1 can recognize that the warning about the alarm A occurred at hh point mm minute ss second on MM DD day YYYY. Similarly, the operator of the factory 1 can recognize the history of the time information indicating the occurrence time of the predetermined state of the other process data affecting the operation efficiency of the factory 1 and the information indicating the content thereof.

在儀表板顯示畫面DP1的區域R12中顯示與工廠1的運轉有關之效率等指標。例如，在區域R12中顯示有為了工廠1的穩定運轉而將重要的指標作為縱軸並將橫軸作為時間之一個或複數個趨勢圖。該等趨勢圖最右端的時刻係計算該等指標之最晚的時刻。In the area R12 of the instrument panel display screen DP1, indicators such as efficiency related to the operation of the factory 1 are displayed. For example, in the area R12, for the stable operation of the factory 1, one or a plurality of trend graphs are displayed in which the vertical axis is an important index and the horizontal axis is one or a plurality of time. The time at the far right of these trend graphs is the latest time for calculating these indicators.

在儀表板顯示畫面DP1的區域R13中，每個警報種類在第1期間內的發生頻率以按每個警報種類排列之態樣顯示。藉此，能夠將每個警報種類在第1期間的發生頻率可視化。因此，不僅僅是掌握有無發生警報而是藉由掌握警報的發生頻率而，例如能夠防止在某一期間內逐漸發展之不良情況。In the area R13 of the instrument panel display screen DP1, the frequency of occurrence of each alarm type in the first period is displayed in a state arranged for each alarm type. Thereby, the frequency of occurrence of each alarm type in the first period can be visualized. Therefore, by grasping not only the presence or absence of an alarm but also the occurrence frequency of the alarm, it is possible to prevent, for example, an inconvenience that gradually develops within a certain period of time.

具體而言，作為「警報合計」資訊，例如在過去24小時內由DCS20判定為異常之次數(發生次數)按每個警報種類進行合計。另外，圖5中的「警報1」、「警報2」等可以顯示用於識別警報的種類之識別資訊。識別資訊例如可以為特定感測器的名稱、由感測器檢測之警報的項目名等。Specifically, as "alarm total" information, for example, the number of times (the number of occurrences) the DCS 20 has determined to be abnormal in the past 24 hours is totaled for each alarm type. In addition, "alarm 1", "alarm 2", etc. in FIG. 5 may display identification information for identifying the type of the alarm. The identification information may be, for example, the name of a specific sensor, the item name of an alarm detected by the sensor, and the like.

而且，與按每個警報種類合計並計算之第1期間內的發生次數相對應之長度的各條形圖以發生次數的降序排列，以所謂的柏拉圖的態樣顯示。另外，顯示於區域R13之各條形圖亦可以以發生次數的升序排列。如此，藉由將與每個警報種類在第1期間的發生頻率相對應之條形圖按每個警報種類以發生頻率的降序或升序排列顯示，能夠使用所謂的柏拉圖來將每個警報種類在第1期間的發生頻率輕易地可視化。Furthermore, each bar graph of the length corresponding to the number of occurrences in the first period, which is aggregated and calculated for each alarm type, is arranged in descending order of the number of occurrences, and displayed in a so-called Platonic form. In addition, the bar graphs displayed in the area R13 may be arranged in ascending order of the number of occurrences. In this way, by displaying the bar graph corresponding to the occurrence frequency of each alarm type in the first period in descending or ascending order of occurrence frequency for each alarm type, it is possible to use so-called Platonics to classify each alarm type in the order of occurrence. The frequency of occurrence of the first period is easily visualized.

若操作者例如在區域R13的「警報1」的條形圖上逐漸移動指針或游標(cursor)並點擊(單擊)，則如圖5所示，顯示該警報種類的內容「警報1」和過去24小時內的發生件數「508件」。For example, when the operator gradually moves the pointer or the cursor on the bar graph of "Alarm 1" in the area R13 and clicks (clicks), as shown in FIG. 5, the contents of the alarm type "Alarm 1" and The number of occurrences in the past 24 hours is "508".

又，若操作者在例如顯示於區域R13之「警報1」的條形圖上逐漸移動指針或游標並雙擊，則由儀表板顯示畫面DP1轉變為發生履歷顯示畫面DP2。Moreover, if the operator gradually moves the pointer or the cursor on the bar graph of "alarm 1" displayed in the area R13 and double-clicks, for example, the instrument panel display screen DP1 is changed to the occurrence history display screen DP2.

另外，每個警報種類在第1期間的發生頻率並不限定於圖5所示之例子的顯示。每個警報種類在第1期間的發生頻率只要為按每個警報種類排列之態樣，則亦可以以其他形式顯示。每個警報種類在第1期間的發生頻率亦可以以圖表形式，例如以折線圖(line graph)、堆疊長條圖(stacked bar graph)、帶狀圖(band graph)等顯示。In addition, the frequency of occurrence of each alarm type in the first period is not limited to the display of the example shown in FIG. 5 . The frequency of occurrence of each alarm type in the first period may be displayed in other forms as long as it is arranged for each alarm type. The frequency of occurrence of each alarm type in the first period can also be displayed in the form of a graph, for example, a line graph, a stacked bar graph, a band graph, and the like.

接著，使用圖6對發生履歷顯示畫面DP2的一例進行說明。發生履歷顯示畫面DP2包括區域R20~ R22。Next, an example of the occurrence history display screen DP2 will be described with reference to FIG. 6 . The occurrence history display screen DP2 includes areas R20 to R22.

在區域R20中顯示「發生日期時間」、「顯示方法」、「項目」、「警報類別」、「最多顯示件數」及「檢索」。區域R20中所包含之「發生日期時間」能夠由操作者雙擊並分別輸入顯示所選擇之警報種類的發生履歷之第2期間的開始時點和結束時點。例如，當圖5所示之每個警報種類的發生頻率的第1期間為過去24小時時，作為第2期間的開始時點及結束時點，能夠輸入過去24小時以內的時間。In the area R20, "occurrence date and time", "display method", "item", "alarm type", "maximum number of displayed items", and "search" are displayed. In the "occurrence date and time" included in the area R20, the operator can double-click and input the start time and end time of the second period in which the occurrence history of the selected alarm type is displayed, respectively. For example, when the first period of the frequency of occurrence of each alarm type shown in FIG. 5 is the past 24 hours, the time within the past 24 hours can be input as the start time and end time of the second period.

區域R20中所包含之「顯示方法」中能夠選擇「一覽」或「圖表」中的一者。當在「顯示方法」中選擇「一覽」時，在區域R20中所包含之「警報類別」中能夠選擇「ALL」、「評量項目」或「DCS」中的任一者。另一方面，當在「顯示方法」中選擇「圖表」時，在區域R20中所包含之「項目」中能夠選擇與所選擇之警報種類相關之相關事件。能夠選擇之相關事件例如最多為5個(5個項目)。在圖6所示之例子中，在「顯示方法」中已選擇「圖表」，在「項目」中已選擇2個(2個項目)的相關事件。From the "display method" included in the area R20, one of "list" and "graph" can be selected. When "List" is selected in "Display method", any one of "ALL", "Evaluation item" or "DCS" can be selected in "Alarm type" included in the area R20. On the other hand, when "Graph" is selected in "Display method", related events related to the selected alarm type can be selected from "Item" included in the area R20. The number of related events that can be selected is, for example, a maximum of five (5 items). In the example shown in FIG. 6, "Graph" has been selected in "Display method", and two related events (two items) have been selected in "Item".

區域R20中所包含之「最多顯示件數」中能夠輸入數值，若選擇(按下)區域R20中所包含之「檢索」的顯示，則從所輸入之第2期間的開始時點至結束時點為止，在儀表板顯示畫面DP1上選擇之警報種類的發生履歷資訊和在區域R20中所包含之「項目」中選擇之相關事件的發生履歷資訊顯示於區域R22。A numerical value can be entered in the "Maximum number of items displayed" included in the area R20, and if the display of "Search" included in the area R20 is selected (pressed), the inputted second period starts from the start time to the end time. , the occurrence history information of the alarm type selected on the dashboard display screen DP1 and the occurrence history information of the related event selected in the "item" included in the area R20 are displayed in the area R22.

在區域R21中顯示「發生日期時間」、「正確/錯誤判定」及「更新」。區域R21中所包含之「發生日期時間」中顯示區域R20中輸入之發生日期時間的開始時點及結束時點。區域R21中所包含之「正確/錯誤判定」中能夠選擇並輸入「正確」或「錯誤」中的一者。換言之，區域R21的「正確/錯誤判定」構成為能夠輸入在儀表板顯示畫面DP1上選擇之警報種類的發生的正確/錯誤。藉此，例如操作者能夠關於看後述之圖表判定之警報種類的發生的正確/錯誤而輸入並登記到系統30或監視裝置40中。若選擇(按下)區域R21中所包含之「更新」的顯示，則顯示於區域R22之警報種類的發生履歷資訊和相關事件的發生履歷資訊被更新為最新的狀態。In the area R21, "date and time of occurrence", "correct/error judgment", and "update" are displayed. The "occurrence date and time" included in the area R21 displays the start time and end time of the occurrence date and time input in the area R20. One of "correct" and "error" can be selected and input from the "correct/error judgment" included in the area R21. In other words, the "correct/error determination" of the area R21 is configured so that the correct/error occurrence of the alarm type selected on the instrument panel display screen DP1 can be input. Thereby, for example, the operator can input and register in the system 30 or the monitoring device 40 the correctness/error of the occurrence of the alarm type determined by looking at the graph to be described later. When the display of "update" included in the area R21 is selected (pressed), the occurrence history information of the alarm type and the occurrence history information of the related event displayed in the area R22 are updated to the latest state.

在區域R22中顯示警報種類在第2期間的發生履歷資訊。如此，藉由關於在儀表板顯示畫面DP1上選擇之警報種類而顯示第2期間的發生履歷資訊，能夠關於該警報種類而掌握第2期間內的例如發生間隔、發生密度、發生時間點等。The occurrence history information of the alarm type in the second period is displayed in the area R22. In this way, by displaying the occurrence history information of the second period with respect to the alarm type selected on the dashboard display screen DP1, it is possible to grasp, for example, the occurrence interval, occurrence density, occurrence time, etc., in the second period with respect to the alarm type.

更詳細而言，依據警報種類在第2期間的發生履歷資訊以按照時間順序排列之圖表形式顯示該警報種類的發生。在圖6所示之例子中，關於警報種類，將橫軸作為時間以按照每次發生時的時間順序標繪(描繪)之圖表進行顯示。如此，藉由關於在儀表板顯示畫面DP1上選擇之警報種類，依據第2期間的發生履歷資訊以按照時間順序排列之圖表形式顯示警報種類的發生，能夠關於該警報種類而輕易地掌握第2期間內的例如發生間隔、發生密度、發生時間點等。More specifically, according to the occurrence history information of the alarm type in the second period, the occurrence of the alarm type is displayed in the form of a graph arranged in chronological order. In the example shown in FIG. 6, the alarm type is displayed in a graph plotted (drawn) in the chronological order of each occurrence with the horizontal axis as time. In this way, by displaying the occurrence of the alarm type in the form of a chronological chart based on the occurrence history information of the second period for the alarm type selected on the instrument panel display screen DP1, it is possible to easily grasp the second alarm type about the alarm type. For example, the occurrence interval, occurrence density, occurrence time point, etc. within the period.

又，在區域R22中還顯示相關事件在第2期間的發生履歷資訊。如此，藉由連同在儀表板顯示畫面DP1上選擇之警報種類的第2期間的發生履歷資訊，顯示相關事件在第2期間的發生履歷資訊，例如能夠掌握該警報種類與相關事件的因果關係或發生該警報種類時工廠的運轉狀態等。In addition, the occurrence history information of the related event in the second period is also displayed in the area R22. In this way, by displaying the occurrence history information of the related event in the second period together with the occurrence history information of the second period of the alarm type selected on the dashboard display screen DP1, it is possible to grasp, for example, the causal relationship between the alarm type and the related event or The operation status of the plant when this type of alarm occurs, etc.

更詳細而言，依據警報種類的第2期間的發生履歷資訊按照時間順序排列該警報種類的發生，並依據相關事件在第2期間的發生履歷資訊以按照時間順序排列之圖表形式顯示該相關事件的發生。在圖6所示之例子中，關於警報種類及相關事件，將橫軸作為時間以按照每次發生時的時間順序標繪(描繪)之圖表進行顯示。在此，當以白色圓圈標繪之警報種類例如為「表示排放氣體中的氮氧化物濃度超出規定值之警報」時，若作為以黑色方塊標繪之相關事件而例如選擇「表示排放氣體中的氧濃度低於規定值之警報」，則警報種類在第2期間的發生履歷資訊和相關事件在第2期間的發生履歷資訊以按照時間順序排列之圖表形式顯示於區域R22，可看出兩者之間具有因果關係。如此，藉由依據在儀表板顯示畫面DP1上選擇之警報種類在第2期間的發生履歷資訊按照時間順序排列該警報種類的發生，並依據相關事件在第2期間的發生履歷資訊以按照時間順序排列之圖表形式顯示該相關事件的發生，例如能夠輕易地掌握該警報種類與相關事件的因果關係或發生該警報種類時工廠的運轉狀態等。In more detail, the occurrence of the alarm type is arranged in chronological order according to the occurrence history information of the alarm type in the second period, and the related events are displayed in a chronological chart according to the occurrence history information of the relevant event in the second period. happened. In the example shown in FIG. 6 , the types of alarms and related events are displayed in a graph plotted (drawn) in the chronological order of each occurrence with the horizontal axis as time. Here, when the alarm type drawn with a white circle is, for example, "an alarm indicating that the concentration of nitrogen oxides in the exhaust gas exceeds a prescribed value", if "an alarm indicating that the concentration of nitrogen oxides in the exhaust gas exceeds a prescribed value" is selected, for example, "indicating that the Oxygen concentration is lower than the specified value", the occurrence history information of the alarm type in the second period and the occurrence history information of the related events in the second period are displayed in the area R22 in the form of a chronological chart. It can be seen that the two There is a causal relationship between them. In this way, according to the occurrence history information of the alarm type selected on the instrument panel display screen DP1 in the second period, the occurrence of the alarm type is arranged in chronological order, and according to the occurrence history information of the relevant event in the second period, the occurrence of the alarm type is arranged in chronological order. The chart format of the arrangement shows the occurrence of the relevant events, for example, it is possible to easily grasp the causal relationship between the alarm type and the relevant event, or the operation status of the factory when the alarm type occurs.

如前所述，與警報種類相關之相關事件係工廠1的流程，或者，係與在儀表板顯示畫面DP1上顯示有第1期間的發生頻率之警報種類不同之種類的警報。藉此，能夠輕易地掌握在儀表板顯示畫面DP1上選擇之警報種類與其他警報或流程的因果關係或發生該警報種類時其他警報或流程的發生狀況等。As described above, the related event related to the alarm type is the flow of the factory 1 or an alarm of a different type from the alarm type in which the frequency of occurrence of the first period is displayed on the instrument panel display screen DP1. Thereby, the causal relationship between the alarm type selected on the dashboard display screen DP1 and other alarms or processes, the occurrence status of other alarms or processes when the alarm type occurs, and the like can be easily grasped.

接著，參考圖7的流程圖對由本實施方式之系統30進行之處理的流程進行說明。該流程圖特別示出顯示與工廠1中發生之警報有關之資訊之處理的流程。該處理藉由控制部31的控制來執行。另外，以下所示之步驟的內容或順序僅為一例，該動作處理並不限定於此。Next, the flow of processing performed by the system 30 of the present embodiment will be described with reference to the flowchart of FIG. 7 . This flowchart particularly shows the flow of the process of displaying information related to an alarm occurring in the factory 1 . This process is executed under the control of the control unit 31 . In addition, the content and order of the steps shown below are merely an example, and the operation processing is not limited to this.

又，在以下的說明中，假設如下：工廠1處於運轉中，取得部311經由DCS20取得工廠1的流程資料並將其儲存於流程資訊DB33A中，並且取得DCS20判定有無工廠1的異常之結果所生成之警報資訊(DCS警報資訊)並將其儲存於警報資訊DB33B中。又，關於系統30判定有無工廠1的異常之結果所生成之警報資訊(系統警報資訊)，亦假設儲存於警報資訊DB33B中。In the following description, it is assumed that the plant 1 is in operation, the acquisition unit 311 acquires the process data of the plant 1 via the DCS 20, stores it in the process information DB 33A, and acquires the result of the determination of the presence or absence of the abnormality of the plant 1 by the DCS 20. The generated alarm information (DCS alarm information) is stored in the alarm information DB33B. In addition, the alarm information (system alarm information) generated as a result of the system 30 judging the presence or absence of an abnormality in the factory 1 is also assumed to be stored in the alarm information DB 33B.

計算部312判定是否已經過規定時間(S11)。在此，規定時間的長度並不受特別限定，例如可以為1秒、5秒、10秒、30秒等秒數單位，亦可以為1分鐘、2分鐘等分鐘單位。然而，規定期間的長度愈短，顯示於儀表板顯示畫面DP1之資訊的即時(realtime)性愈提高，因此為較佳。該規定時間的長度可以由操作者等任意設定。計算部312重複步驟S11，直至判定為已經過規定時間。The calculation unit 312 determines whether or not a predetermined time has elapsed (S11). Here, the length of the predetermined time is not particularly limited, and may be in seconds such as 1 second, 5 seconds, 10 seconds, and 30 seconds, or may be in minutes such as 1 minute and 2 minutes. However, the shorter the length of the predetermined period, the higher the realtime property of the information displayed on the instrument panel display screen DP1, which is preferable. The length of the predetermined time can be arbitrarily set by an operator or the like. The calculation unit 312 repeats step S11 until it is determined that the predetermined time has elapsed.

當判定為已經過規定期間時(S11；「是」)，計算部312依據儲存於警報資訊DB33B中之警報資訊，按每個警報種類計算第1期間的發生頻率(S12)。When it is determined that the predetermined period has elapsed ( S11 ; YES), the calculation unit 312 calculates the frequency of occurrence of the first period for each alarm type based on the alarm information stored in the alarm information DB 33B ( S12 ).

接著，顯示控制部315將由計算部312計算之每個警報種類在第1期間的發生頻率以按每個警報種類排列之態樣顯示於儀表板顯示畫面DP1的區域R13(S13)。例如，如圖5所示，顯示控制部315以按發生頻率的降序或升序排列之態樣顯示與每個警報種類的發生頻率相對應之長度的條形圖。Next, the display control part 315 displays the frequency of occurrence of each alarm type in the first period calculated by the calculation part 312 in the area R13 of the instrument panel display screen DP1 in a state arranged for each alarm type (S13). For example, as shown in FIG. 5 , the display control unit 315 displays a bar graph with a length corresponding to the occurrence frequency of each alarm type in a descending or ascending order of the occurrence frequency.

接著，生成部313判定是否已選擇顯示於儀表板顯示畫面DP1的區域R13之複數個警報種類中的一個(S14)。如前所述，操作者例如能夠藉由將指針或游標逐漸移動到顯示於區域R13之每個警報種類的條形圖之一上並雙擊來選擇警報種類。生成部313重複步驟S14，直至判定為已選擇複數個警報種類中的一個。Next, the generation unit 313 determines whether or not one of the plurality of alarm types displayed in the area R13 of the instrument panel display screen DP1 has been selected ( S14 ). As previously described, the operator can select an alarm type, for example, by gradually moving the pointer or cursor over one of the bar graphs displayed for each alarm type in the area R13 and double-clicking. The generation unit 313 repeats step S14 until it is determined that one of the plurality of alarm types has been selected.

當判定為已選擇複數個警報種類中的一個時(S14；「是」)，受理部314在操作者已選擇相關事件時接收該選擇(S15)。例如，顯示控制部315顯示發生履歷顯示畫面DP2，受理部314根據操作者對發生履歷顯示畫面DP2的區域R20的操作來接收與在步驟S14中選擇之警報種類相關之相關事件的選擇。When it is determined that one of the plurality of alarm types has been selected ( S14 ; YES), the accepting unit 314 receives the selection when the operator has selected the relevant event ( S15 ). For example, the display control unit 315 displays the occurrence history display screen DP2, and the accepting unit 314 receives selection of a related event related to the alarm type selected in step S14 according to the operator's operation on the area R20 of the occurrence history display screen DP2.

接著，生成部313依據儲存於警報資訊DB33B中之警報資訊，關於在步驟S14中選擇之警報種類而生成表示第2期間的發生履歷之發生履歷資訊，並且依據儲存於流程資訊DB33A中之流程資訊或儲存於警報資訊DB33B中之警報資訊，關於在步驟S15中接收了選擇之相關事件而生成表示第2期間的發生履歷之發生履歷資訊(S16)。Next, the generation unit 313 generates occurrence history information indicating the occurrence history of the second period based on the alarm information stored in the alarm information DB 33B for the alarm type selected in step S14, and also according to the flow information stored in the flow information DB 33A Or the alarm information stored in the alarm information DB 33B generates occurrence history information indicating the occurrence history of the second period with respect to the relevant event selected in step S15 ( S16 ).

接著，顯示控制部315使在步驟S15中生成之警報種類在第2期間的發生履歷資訊和相關事件在第2期間的發生履歷資訊顯示於發生履歷顯示畫面DP2的區域R22(S17)。另外，警報種類在第2期間的發生履歷資訊和相關事件在第2期間的發生履歷資訊的顯示可以為圖6所示之圖表形式，亦可以為一覽形式。以上，處理結束。Next, the display control unit 315 causes the occurrence history information of the alarm type generated in step S15 in the second period and the occurrence history information of the related event in the second period to be displayed in the area R22 of the occurrence history display screen DP2 (S17). In addition, the display of the occurrence history information of the alarm type in the second period and the occurrence history information of the related event in the second period may be in the form of a graph as shown in FIG. 6 or in the form of a list. As described above, the process ends.

如上，依本實施方式，每個警報種類在第1期間的發生頻率以按每個警報種類排列之態樣顯示。藉此，能夠將每個警報種類在第1期間的發生頻率可視化。因此，不僅僅是掌握有無發生警報而是藉由掌握警報的發生頻率而，例如能夠防止在某一期間內逐漸發展之不良情況。As described above, according to the present embodiment, the frequency of occurrence of each alarm type in the first period is displayed in a state arranged for each alarm type.
