Description

顯示裝置、顯示方法、控制裝置及電腦程式Display device, display method, control device and computer program

本發明有關顯示裝置、顯示方法、控制裝置及電腦程式。The present invention relates to a display device, a display method, a control device and a computer program.

一直以來，在工廠等監視對象中設置感測器，根據感測器取得之資料，對監視對象設備的運轉情況進行監視。Conventionally, sensors have been installed in monitoring objects such as factories, and the operation of monitoring objects has been monitored based on the data acquired by the sensors.

專利文獻1中記載有一種線上監視裝置，其能夠減少用以確認監視對象的狀態之畫面操作作業的負擔。該線上監視裝置具備從複數個候補畫面中決定要顯示的畫面之圖像顯示資訊生成機構。 [先前技術文獻] Patent Document 1 describes an on-line monitoring device capable of reducing the burden of screen operation work for checking the state of a monitoring object. The online monitoring device includes image display information generating means for determining a screen to be displayed from among a plurality of candidate screens. [Prior Art Literature]

[專利文獻1] 日本特開2018-106432號公報[Patent Document 1] Japanese Patent Laid-Open No. 2018-106432

[發明所欲解決之問題][Problems to be Solved by Invention]

此類監視對象中發生異常時，會發出警告。為了探討警告的妥當性，操作員閱覽根據從感測器取得的資料生成之圖表。A warning is issued when an exception occurs in this type of monitoring object. To discuss the validity of the warning, the operator views a graph generated from data obtained from the sensor.

然而，專利文獻1中記載之線上監視裝置“自動選擇”必要的資訊並顯示於畫面以實現“缺乏經驗的操作員亦能夠像熟練工一樣處理”([發明所欲解決之問題])，因此存在大量應顯示的圖表時，圖表的確認需要大量時間。例如，即使是熟練的操作員，亦需要閱覽與缺乏經驗的操作員相同的圖表。However, the on-line monitoring device described in Patent Document 1 "automatically selects" necessary information and displays it on the screen so that "an inexperienced operator can handle it like a skilled worker" ([Problem to be Solved by the Invention]), so there is When there are a large number of graphs to be displayed, confirmation of the graphs takes a lot of time. For example, even a skilled operator needs to read the same charts as an inexperienced operator.

為了減少應顯示的圖表，可以考慮對每個警告預先設定應顯示的代表性圖表。然而，若確定每個警告所要顯示的圖表，則有時會從確認對象中漏掉原本應確認的圖表。例如，缺乏經驗的操作員有可能會看漏必須確認的圖表。In order to reduce the number of graphs that should be displayed, it may be considered to preset a representative graph to be displayed for each warning. However, if the graph to be displayed for each warning is determined, the graph that should be confirmed may be missed from the confirmation target. For example, an inexperienced operator may miss a chart that must be validated.

因此，本發明的目的在於提供一種能夠有效地確認應確認的圖表之顯示裝置、顯示方法、控制裝置及電腦程式。 [解決問題之技術手段] Therefore, an object of the present invention is to provide a display device, a display method, a control device, and a computer program capable of effectively checking a graph to be checked. [Technical means to solve problems]

[工廠的說明]圖1係表示運用本發明之監視對象的一例工廠1的整體結構之概略圖。例如，本實施形態之工廠1係具備使在高溫下流動的矽砂等循環材料循環的同時燃燒燃料來產生蒸氣之循環流體化床鍋爐(Circulating Fluidized Bed型)之發電廠。作為工廠1的燃料，除了煤等化石燃料以外，例如能夠使用非化石燃料(木質生物質、廢輪胎、廢塑膠、污泥等)。工廠1中產生之蒸氣用於驅動渦輪機100。[Description of Factory] FIG. 1 is a schematic diagram showing the overall configuration of an example of a factory 1 to which the monitoring object of the present invention is applied. For example, the factory 1 of the present embodiment is a power plant equipped with a circulating fluidized bed boiler (Circulating Fluidized Bed type) that burns fuel while circulating a circulating material such as silica sand flowing at a high temperature to generate steam. As the fuel of 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 plant 1 is used to drive turbine 100 .

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的下部與燃燒爐2的下部透過流路變窄的環封部4a連接。藉此，成為循環材料回收管4的下部儲存有預定量的循環材料之狀態。將藉由旋風器3去除了循環材料之廢氣經由廢氣流路3a供給至後部煙道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 portion of the circulating material recovery pipe 4 is connected to the lower portion of the combustion furnace 2 through a ring seal portion 4a in which the flow passage is narrowed. Thereby, a predetermined amount of circulating material is stored in the lower part of the circulating 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 through the exhaust gas flow path 3a.

鍋爐具備用以燃燒燃料的燃燒爐2和用以使用藉由燃燒獲得之熱產生水蒸氣等的熱交換器。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。將從未圖示之燃料供給裝置供給至燃燒爐2之燃料透過燃料供給口2a供給至燃燒爐2的內部。又，燃燒爐2的爐壁上設置有用以加熱鍋爐給水的爐壁管6。藉由在燃燒爐2中的燃燒加熱流經爐壁管6之鍋爐給水。The boiler includes a combustion furnace 2 for burning fuel, and a heat exchanger for generating steam or the like using 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. In addition, the furnace wall of the combustion furnace 2 is provided with a furnace wall tube 6 for heating boiler feed water. The boiler feed water 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2c導入之燃燒/流動用空氣，包含從燃料供給口2a供給之燃料之固態物流動，燃料流動的同時在例如約800~900℃下燃燒。在燃燒爐2內產生之燃燒氣體伴隨循環材料被導入至旋風器3。旋風器3藉由離心分離作用分離循環材料與氣體，透過循環材料回收管4使被分離之循環材料返回燃燒爐2，並且將去除了循環材料之燃燒氣體從廢氣流路3a送出至後部煙道5。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 pipe 2c, and the fuel flows while burning at, for example, about 800 to 900°C. The combustion gas generated in the combustion furnace 2 is introduced into the cyclone 3 along with the circulating material. The cyclone 3 separates the circulating material and the gas by centrifugal separation, returns the separated circulating material to the combustion furnace 2 through the circulating material recovery pipe 4, and sends the combustion gas with the circulating material removed from the exhaust gas flow path 3a to the rear flue 5.

燃燒爐2中，在底部滯留被稱為爐內機床材料的循環材料的一部分。在該機床材料中有時會包含不適合循環流動的具有粗粒徑之機床材料、排燃雜質，有時會因該等不適合作為循環材料的機床材料發生流動不良。因此，為了抑制流動不良，在燃燒爐2中，爐內機床材料從底部的排出口2d連續或間歇地排出至外部。被排出之機床材料在未圖示之循環管上去除金屬、粗大粒徑等不適物之後，再次供給至燃燒爐2或直接廢棄。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構成之循環系統內部循環。In the combustion furnace 2, a part of the circulating material called in-furnace machine tool material accumulates at the bottom. The machine tool material may contain coarse-grained machine tool materials that are not suitable for circulating flow, and combustion impurities may be included, and flow failure may occur due to these machine tool materials that are not suitable for circulating flow. Therefore, in order to suppress poor flow, in the combustion furnace 2, the machine tool material in the furnace is continuously or intermittently discharged to the outside from the discharge port 2d at the bottom. The discharged machine tool material is supplied to the combustion furnace 2 again or discarded directly after removing undesired substances such as metals and coarse particles on a circulation pipe (not shown). The circulating material of the combustion furnace 2 circulates inside 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排出之氣體流入後段之流路。後部煙道5具有產生過熱蒸氣之過熱器10和預熱鍋爐給水之節能器12作為回收廢氣的熱之排熱回收部。流經後部煙道5之廢氣藉由與流通過熱器10及節能器12之蒸氣或鍋爐給水進行熱交換而被冷卻。又，具有儲存通過了節能器12之鍋爐給水之汽鼓8，汽鼓8亦與爐壁管6連接。The rear flue 5 has a flow path through which the gas discharged from the cyclone 3 flows into the rear stage. The rear flue 5 has a superheater 10 for generating superheated steam and an economizer 12 for preheating boiler feed water as a heat recovery part for recovering the heat of the exhaust gas. The exhaust gas flowing through the rear flue 5 is cooled by heat exchange with steam or boiler feed water flowing through the superheater 10 and economizer 12 . In addition, there is a steam drum 8 for storing boiler feed water passing through the economizer 12 , and the steam drum 8 is also connected to the furnace wall tube 6 .

節能器12將廢氣的熱傳遞至鍋爐給水而預熱鍋爐給水。節能器12藉由管21與泵7連接，同時藉由管22與汽鼓8連接。將從泵7經由管21供給至節能器12並藉由節能器12預熱之鍋爐給水經由管22供給至汽鼓8。The economizer 12 transfers the heat of the exhaust gas to the boiler feedwater to preheat the boiler feedwater. The economizer 12 is connected to the pump 7 via a pipe 21 and to the steam drum 8 via a pipe 22 . The boiler feed water supplied from the pump 7 via the pipe 21 to the economizer 12 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內的鍋爐給水從降水管8a下降並在燃燒爐2的下部側被導入至爐壁管6流向汽鼓8。爐壁管6內的鍋爐給水藉由產生於燃燒爐2內之燃燒熱被加熱，在汽鼓8內蒸發成為蒸氣。The steam drum 8 is connected with a dewatering pipe 8a and a furnace wall pipe 6 . The boiler feed water in the steam drum 8 descends from the downpipe 8 a and is introduced into the furnace wall tube 6 at the lower side of the combustion furnace 2 to flow toward the steam drum 8 . The boiler feed water 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氣之飽和蒸氣管8b。飽和蒸氣管8b連接汽鼓8與過熱器10。將汽鼓8內的蒸氣經由飽和蒸氣管8b供給至過熱器10。過熱器10利用廢氣的熱使蒸氣過熱而生成過熱蒸氣。將過熱蒸氣通過管10a供給至工廠1外的渦輪機100而用於發電。The steam drum 8 is connected to 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 generates superheated steam by superheating the steam by utilizing the heat of the exhaust gas. The superheated steam is supplied to the turbine 100 outside the factory 1 through the pipe 10a to generate electricity.

從渦輪機100排出之蒸氣的壓力和溫度低於從過熱器10排出之蒸氣的壓力和溫度。雖沒有特別限定，供給至渦輪機100之蒸氣的壓力為約10~17MPa左右，溫度為約530~570℃左右。從渦輪機100排出之蒸氣的壓力為約3~5MPa左右，溫度為約350~400℃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. 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.

在渦輪機100的下游設置有冷凝器102。將從渦輪機100排出之蒸氣供給至冷凝器102，在冷凝器102中凝結而返回飽和水之後將其供給至泵7。渦輪機100上連接有將藉由渦輪機100的旋轉獲得之動能轉換成電能之發電機。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 . The turbine 100 is connected with a generator that converts kinetic energy obtained by the rotation of the turbine 100 into electrical energy.

泵7a供給補給水以將冷凝器102的水位保持恆定。圖1中，示出藉由泵7a補給的補給水流量u1(“製程資料”的一例)。The pump 7a supplies make-up water to keep the water level of the condenser 102 constant. In FIG. 1, the make-up water flow rate u1 supplied by the pump 7a (an example of "process data") is shown.

本實施形態中處理的製程資料可以為與工廠1有關之任意資料，例如，可以為藉由感測器測定工廠1的狀態之資料(“製程資料”的一例)，更具體而言，可以包括工廠1的溫度、壓力及流量等的測定值。在圖1中示出從泵7供給至節能器12之鍋爐給水流量u2(“製程資料”的一例)。進而，在圖1中示出從過熱器10供給至渦輪機100之鍋爐出口蒸氣流量u3(“製程資料”的一例)，並示出從汽鼓8供給至過熱器10之飽和蒸氣流量u4(“製程資料”的一例)。另外，補給水流量u1可以控制為追隨飽和蒸氣流量u4。又，可以控制為監視鍋爐出口蒸氣流量u3(或過熱蒸氣流量)和汽鼓8的液面水平兩者的同時調節鍋爐給水流量u2。The process data processed in this embodiment may be any data related to the factory 1. For example, it may be data for measuring the state of the factory 1 by a sensor (an example of "process data"). More specifically, it may include Measured values of temperature, pressure, flow rate, etc. at Plant 1. FIG. 1 shows the boiler feed water flow rate u2 (an example of "process 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 "process data"), and shows the saturated steam flow u4 supplied from the steam drum 8 to the superheater 10 ("Process data") Process Data"). In addition, the makeup water flow rate u1 can be controlled to follow the saturated steam flow rate u4. In addition, it is possible to control the boiler feed water flow rate u2 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 .

構成工廠1之管系統中產生破洞時，補給水流量u1上升或鍋爐給水流量u2與鍋爐出口蒸氣流量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、鍋爐給水流量u2、鍋爐出口蒸氣流量u3及飽和蒸氣流量u4等工廠1的製程資料，監視工廠1的運轉情況，並監視工廠1是否發生異常。如下所述，監視裝置40根據按每個異常的種類設定之警報判定邏輯，評價製程資料，在判斷為發生了異常時，使顯示裝置40發出警報。When a hole occurs in the pipe system constituting the plant 1, the flow rate u1 of the makeup water increases or the flow rate difference between the flow rate u2 of the boiler feed water and the flow rate u3 of the boiler outlet steam increases. DCS (Distributed Control System: Distributed Control System, Fig. 2) 20 receives the process data of Factory 1, such as make-up water flow rate u1, boiler feed water flow rate u2, boiler outlet steam flow rate u3, and saturated steam flow rate u4, from Factory 1, and monitors the operation of Factory 1 situation and monitor plant 1 for exceptions. As described below, the monitoring device 40 evaluates the process data based on the alarm determination logic set for each type of abnormality, and when it is determined that an abnormality has occurred, the display device 40 generates an alarm.

另外，作為製程資料，例示了補給水流量u1、鍋爐給水流量u2、鍋爐出口蒸氣流量u3及飽和蒸氣流量u4，但與工廠1有關之製程資料亦可以為其他資料。與工廠1有關之製程資料可以為根據溫度、壓力等其他資料或複數個製程資料算出之資料，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 feed water flow u2, the boiler outlet steam flow u3 and the saturated steam flow u4 are exemplified, but the process data related to the plant 1 may be other data. The process data related to Factory 1 may be data calculated based on other data such as temperature, pressure, or a plurality of process data, or may be data obtained from sensors and the like without calculation processing.

圖2係本實施形態之工廠1、DCS20及運轉支援系統30的功能方塊圖。FIG. 2 is a functional block diagram of the factory 1, the DCS 20, and the operation support system 30 of the present embodiment.

DCS20係用以控制工廠1的分散控制系統。DCS20從設置於工廠1之感測器等取得製程資料，並根據此，將用以控制工廠1的控制訊號供給至工廠1。DCS20 is a distributed control system used to control Factory 1. The DCS 20 obtains the process data from the sensor etc. provided in the factory 1, and supplies the control signal for controlling the factory 1 to the factory 1 according to this.

運轉支援系統30具有從DCS20取得製程資料之邊緣/雲端運算部32、從邊緣/雲端運算部32取得製程資料並根據製程資料監視工廠1之監視裝置40、將工廠1的運轉情況顯示給操作員的顯示裝置50。監視裝置40(“控制裝置”的一例)亦作為控制顯示裝置50之控制裝置發揮作用。具體而言，監視裝置40取得製程資料，並根據此判斷有無異常，在判斷為發生了異常時，使顯示裝置50發出警報(“警告”的一例)。發出警報時，監視裝置40從後述資料庫取得導引資訊(後述)等發出警報時顯示之資訊，並顯示於顯示裝置50的顯示畫面。The operation support system 30 has an edge/cloud computing unit 32 that acquires process data from the DCS 20, a monitoring device 40 that acquires process data from the edge/cloud computing unit 32 and monitors the factory 1 based on the process data, and displays the operation status of the factory 1 to the operator display device 50. The monitoring device 40 (an example of the “control device”) also functions as a control device that controls the display device 50 . Specifically, the monitoring device 40 obtains the process data, determines whether or not there is an abnormality based on this, and when it is determined that an abnormality has occurred, causes the display device 50 to issue an alarm (an example of "warning"). When an alarm is issued, the monitoring device 40 acquires information displayed when an alarm is issued, such as guidance information (described later), from a database to be described later, and displays it on the display screen of the display device 50 .

邊緣/雲端運算部32具備分散配置於網路的周緣部之複數個邊緣伺服器和從複數個邊緣伺服器收集製程資料並提供至監視裝置40之雲端資料伺服器。藉由具備邊緣/雲端運算部32，能夠從大規模監視裝置、分散成複數個之監視裝置較佳地收集製程資料。然而，運轉支援系統30不必一定要具備邊緣/雲端運算部32。此時，運轉支援系統30透過網路，從DCS20取得製程資料。The edge/cloud computing unit 32 includes a plurality of edge servers distributed on the periphery of the network, and a cloud data server that collects process data from the plurality of edge servers and provides them to the monitoring device 40 . By having the edge/cloud computing unit 32, it is possible to collect process data preferably from a large-scale monitoring device or a plurality of monitoring devices that are dispersed. However, the operation support system 30 does not necessarily have to include the edge/cloud computing unit 32 . At this time, the operation support system 30 acquires the process data from the DCS 20 through the network.

監視裝置40具備警報顯示控制部42和記憶部44。 警報顯示控制部42具備：從邊緣/雲端運算部32取得製程資料之製程資料取得部42A；根據藉由製程資料取得部42A取得之製程資料判定是否需要發出警報之警報判定部42B；由警報判定部42B判定為需要發出警報時，根據過去發生的警報時閱覽之圖表的歷程，生成圖表推薦列表(“圖表的選項”的一例)之圖表推薦順序算出部42C；由警報判定部42B判定為需要發出警報時，使與該警報相關之資訊顯示於顯示裝置50之警報確認顯示部42D；及收集由操作員選擇的圖表顯示於顯示裝置50的顯示畫面之情況作為圖表顯示實績之圖表顯示實績收集部42E。 The monitoring device 40 includes an alarm display control unit 42 and a memory unit 44 . The alarm display control unit 42 includes: a process data acquisition unit 42A for acquiring process data from the edge/cloud computing unit 32; an alarm determination unit 42B for determining whether an alarm needs to be issued based on the process data acquired by the process data acquisition unit 42A; When the unit 42B determines that it is necessary to issue an alarm, the chart recommendation order calculation unit 42C generates a chart recommendation list (an example of "table options") based on the history of the charts viewed at the time of the alarm that occurred in the past; the alarm determination unit 42B determines that it is necessary When an alarm is issued, the information related to the alarm is displayed on the alarm confirmation display unit 42D of the display device 50; and the graphs selected by the operator are collected and displayed on the display screen of the display device 50 as the graph display results collection of graph display results Section 42E.

監視裝置的記憶部44具備警報設定DB44A、警報發生歷程DB44B、圖表設定DB44C、圖表閲覧歷程DB44D及導引資訊DB44E。首先，對記憶部44的各資料庫進行說明。The memory unit 44 of the monitoring device includes an alarm setting DB 44A, an alarm occurrence history DB 44B, a graph setting DB 44C, a graph reading history DB 44D, and a guidance information DB 44E. First, each database of the memory unit 44 will be described.

警報設定DB44A儲存用以根據製程資料判斷是否發生顯示工廠1的異常等之警報的警報判定邏輯(判斷基準)。圖3A中示出儲存於警報設定DB44A之資訊的一例。圖3A中，在每一行示出警報的識別資訊(ID)、該警報的分類資訊(“大分類”、“中分類”及“小分類”)及與該警報相關之評價項目名稱。與評價項目名稱建立關聯地記錄警報判定邏輯。警報判定邏輯可以遵循從單個感測器取得之製程資料，亦可以按照預定的演算法(包括遵循藉由機器學習生成之預定的預訓練模型及遵循藉由對複數個感測器的製程資料進行多變量分析等導出之數學模型。)，遵循從複數種感測器取得之製程資料。The alarm setting DB 44A stores an alarm judgment logic (judgment criterion) for judging whether or not an alarm indicating an abnormality of the plant 1 or the like occurs or not based on the process data. FIG. 3A shows an example of the information stored in the alarm setting DB 44A. In FIG. 3A , the identification information (ID) of the alarm, the classification information of the alarm (“large classification”, “medium classification” and “small classification”) and the name of the evaluation item related to the alarm are shown in each row. The alarm decision logic is recorded in association with the evaluation item name. The alarm decision logic can follow the process data obtained from a single sensor, or it can follow a predetermined algorithm (including following a predetermined pre-training model generated by machine learning and following the process data obtained by multiple sensors). Mathematical models derived from multivariate analysis, etc.), following process data obtained from multiple sensors.

警報發生歷程DB44B儲存與過去發出的警報有關之資訊。具體而言，記錄與過去發出的警報相關之資訊及該警報的發生日期等。The alarm occurrence history DB 44B stores information on alarms issued in the past. Specifically, information related to an alarm issued in the past, the date of occurrence of the alarm, and the like are recorded.

圖表設定DB44C儲存與能夠根據製程資料生成的圖表有關之資訊。圖3B中示出儲存於圖表設定DB44C之資訊的一例。圖3B中，每一行示出登錄名和圖表的種類。將登錄名(“圖表的說明”的一例)決定為記載圖表中顯示之評價項目，相當於說明圖表之資訊。又，圖表設定DB44C中亦記錄有成為評價項目的基礎之製程資料的訊號名，例如若操作員雙擊(選擇)一個圖表，則顯示對應之製程資料的訊號名。另外，操作員能夠訪問圖表設定DB44C並編輯記錄於同資料庫之圖表的內容。又，能夠在該資料庫登錄新圖表。Chart Settings DB44C stores information about charts that can be generated from process data. FIG. 3B shows an example of the information stored in the graph setting DB 44C. In FIG. 3B, each row shows the login name and the type of chart. The login name (an example of "description of graph") is determined as the evaluation item displayed in the description graph, which corresponds to the information of the explanatory graph. In addition, the chart setting DB44C also records the signal name of the process data that is the basis of the evaluation item. For example, if the operator double-clicks (selects) a chart, the signal name of the corresponding process data is displayed. In addition, the operator can access the chart setting DB44C and edit the contents of the chart recorded in the same database. Also, a new graph can be registered in the database.

圖表閲覧歷程DB44D儲存發出過去的警報時閱覽之圖表的歷程資訊。圖3C中示出儲存於圖表閲覧歷程DB44D之資訊的一例。本實施形態中，圖表閲覧歷程DB44D將發出過去的警報時的圖表的顯示次數作為得分值，按每一圖表(記載為“圖表(chart)1”等)儲存。圖3C中，作為一例，示出記錄有如下情況之內容：發出與“凝聚(agglomeration)偵知”有關之警報時，過去被稱為“圖表(chart)1”(實際為圖3B中圖表的登錄名)的圖表顯示了30次，被稱為“圖表(char)2”的圖表顯示了21次，被稱為“圖表(chart)3”的圖表顯示了5次。Chart View History DB44D stores history information of charts viewed when past alarms were issued. An example of the information stored in the graph reading history DB44D is shown in FIG. 3C. In the present embodiment, the chart reading history DB 44D stores the number of times of displaying the chart at the time of issuing the past alarm as a score value for each chart (referred to as "chart 1" or the like). In FIG. 3C , as an example, it is shown that the following is recorded: when an alarm related to "agglomeration detection" is issued, what was called "chart 1" in the past (actually, it is the part of the chart in FIG. 3B ) is shown. login) is shown 30 times, the chart called "chart 2" is shown 21 times, and the chart called "chart 3" is shown 5 times.

導引資訊DB44E儲存用以導引發出警報時的對應方法的資訊。例如，在導引資訊DB44E中，按每一警報記錄有說明從標題為“1.監視點(圖表的讀取方法)”的圖表捕捉現象的方法之文章和說明用以優化標題為“2.對應方法”的製程資料的狀態的方法之文章。另外，用以優化製程資料的狀態的方法係指用以優化所關注的製程資料超過臨限值之狀態並設為臨限值以內的方法。The guidance information DB 44E stores information for guiding the corresponding method when an alarm is raised. For example, in the guidance information DB44E, an article describing a method of capturing a phenomenon from the graph titled "1. Monitoring point (graph reading method)" is recorded for each alarm and an explanation for optimizing the title "2. An article on the method for the status of the process data corresponding to the method". In addition, the method for optimizing the state of the process data refers to a method for optimizing the state of the process data of interest exceeding the threshold value and setting it within the threshold value.

圖3D中示出所發出的警報為“循環系統溫度差1”時，顯示於顯示裝置50的顯示畫面之導引資訊的一例。“1.監視點(圖表的讀取方法)”中記載有爐內溫度差的定義和計算式。根據此類說明文，能夠確認從圖表捕捉現象的方法，容易理解正在發生什麼樣的現象。“2.對應方法”中列出了操作員應根據爐內溫度差的大小確認的項目。根據此類說明文，能夠確認用以優化製程資料的狀態的方法。另外，導引資訊除了包括文字資訊、數式等以外，亦可包括圖像、圖例圖表等。進而，亦可以具備顯示相同的警報在過去發出的時刻之功能。FIG. 3D shows an example of the guidance information displayed on the display screen of the display device 50 when the issued alarm is "circulation system temperature difference 1". The definition and calculation formula of the temperature difference in the furnace are described in "1. Monitoring point (graph reading method)". With these explanations, it is possible to confirm the method of capturing the phenomenon from the chart, and it is easy to understand what kind of phenomenon is occurring. "2. Correspondence method" lists the items that the operator should check according to the size of the temperature difference in the furnace. According to such a description, a method for optimizing the state of the process data can be confirmed. In addition, in addition to text information, mathematical formulas, etc., the guidance information may also include images, legends, charts, and the like. Furthermore, it is also possible to have a function of displaying the time when the same alarm was issued in the past.

接著，對警報顯示控制部42的各功能方塊進行說明。 製程資料取得部42A從邊緣/雲端運算部32取得製程資料。 Next, each functional block of the alarm display control unit 42 will be described. The process data acquisition unit 42A acquires process data from the edge/cloud computing unit 32 .

警報判定部42B根據製程資料，判斷有無發生工廠1的異常等，在判斷為發生了異常時，使顯示裝置50發出警報。具體而言，警報判定部42B讀取記錄於警報設定DB44A之警報判定邏輯(判斷基準)，按照該警報判定邏輯，評價製程資料。例如，警報判定部42B根據警報判定邏輯評價預定的製程資料，判斷有無發生被稱為爆裂(如鍋爐管滲漏，構成鍋爐之管(tube)及管道(pipe)等金屬材料受損而破洞，內部的蒸氣洩漏到外部之狀態。包括日後發生爆裂的可能性高的狀態。以下相同)的有可能在工廠1中發生的異常。The alarm determination unit 42B determines whether or not an abnormality has occurred in the factory 1 based on the process data, and when it is determined that an abnormality has occurred, causes the display device 50 to issue an alarm. Specifically, the alarm determination unit 42B reads the alarm determination logic (determination criterion) recorded in the alarm setting DB 44A, and evaluates the process data according to the alarm determination logic. For example, the alarm determination unit 42B evaluates the predetermined process data according to the alarm determination logic, and determines whether or not a burst (such as a boiler tube leakage, damage to metal materials such as tubes and pipes constituting the boiler, etc.) has occurred and a hole has occurred , the state in which the internal steam leaks to the outside. Including the state with a high possibility of explosion in the future. The same as the following), there may be an abnormality in Factory 1.

進而，若警報判定部42B判斷為發生異常，則在警報發生歷程DB44B中記錄與警報有關之資訊(具體而言，警報的名稱及發生日期等資訊)。又，從警報發生歷程DB44B讀取與過去的警報有關之資訊，並將其和與發出的警報有關之資訊一同提供至警報確認顯示部42D。Furthermore, when the alarm determination unit 42B determines that an abnormality has occurred, the alarm occurrence history DB 44B records information related to the alarm (specifically, information such as the name of the alarm and the date of occurrence). Moreover, the information regarding past alarms is read from the alarm occurrence history DB 44B, and is supplied to the alarm confirmation display unit 42D together with the information regarding the issued alarms.

圖表推薦順序算出部42C生成過去發出的警報時閱覽之圖表的歷程，圖表推薦列表，並提供至警報確認顯示部42D。具體而言，若由警報判定部42B判定為需要發出警報，則圖表推薦順序算出部42C訪問圖表閲覧歷程DB44D，並取得與該警報建立關聯之複數個圖表和各圖表的得分值。又，圖表推薦順序算出部42C訪問圖表設定DB44C，並取得與各圖表對應之製程資料的訊號名。然後，圖表推薦順序算出部42C生成圖表推薦列表。The chart recommendation order calculation unit 42C generates a history of charts viewed at the time of an alarm issued in the past, a chart recommendation list, and provides them to the alarm confirmation display unit 42D. Specifically, when the alarm determination unit 42B determines that an alarm needs to be issued, the chart recommendation order calculation unit 42C accesses the chart reading history DB 44D, and acquires a plurality of charts associated with the alarm and the score value of each chart. Moreover, the chart recommendation order calculation part 42C accesses the chart setting DB 44C, and acquires the signal name of the process data corresponding to each chart. Then, the chart recommendation order calculation unit 42C generates a chart recommendation list.

圖4中例示圖表推薦列表的一例。如圖4所示，警報係“循環系統溫度差1”時，顯示圖表名為“循環系統溫度差1(粗粒化偵知用)-按條件”，對應之製程資料將“鍋爐負荷(基於出熱)(%)”作為X軸，將“爐內溫度差(燃燒爐上部‐燃燒爐底)”作為Y軸的圖表的得分值為90的情況。圖表推薦順序算出部42C將所生成之圖表推薦列表提供至警報確認顯示部42D。An example of the chart recommendation list is illustrated in FIG. 4 . As shown in Figure 4, when the alarm is "Circulation system temperature difference 1", the display chart is named "Circulation system temperature difference 1 (for coarse graining detection) - according to conditions", and the corresponding process data will be "Boiler load (based on Heat generation) (%)" as the X-axis, and a graph with "in-furnace temperature difference (combustion furnace upper part-combustion furnace bottom)" as the Y axis has a score value of 90. The chart recommendation order calculation unit 42C supplies the generated chart recommendation list to the alarm confirmation display unit 42D.

由警報判定部42B判定為需要發出警報時，警報確認顯示部42D使顯示裝置50顯示操作員用以確認警報的資訊。圖5示出發出警報時顯示於顯示裝置50的顯示畫面之資訊的一例。在顯示畫面的第1區域AR1中，以列表形式顯示從警報判定部42B取得之與過去及當前的警報有關之資訊。When the alarm determination unit 42B determines that it is necessary to issue an alarm, the alarm confirmation display unit 42D causes the display device 50 to display information for the operator to confirm the alarm. FIG. 5 shows an example of information displayed on the display screen of the display device 50 when an alarm is issued. In the first area AR1 of the display screen, information on past and current alarms acquired from the alarm determination unit 42B is displayed in a list format.

又，若操作員雙擊(選擇)預定的警報AL1，則警報確認顯示部42D從圖表推薦順序算出部42C取得與該警報AL1對應之圖表推薦列表GL1。在相同的顯示畫面的第2區域AR2顯示圖表推薦列表GL1。進而，警報確認顯示部42D可以訪問導引資訊DB44E，讀取與該警報對應之導引資訊，並顯示於顯示畫面的不同區域。When the operator double-clicks (selects) a predetermined alarm AL1, the alarm confirmation display unit 42D acquires the chart recommendation list GL1 corresponding to the alarm AL1 from the chart recommendation order calculation unit 42C. The chart recommendation list GL1 is displayed in the second area AR2 of the same display screen. Furthermore, the alarm confirmation display part 42D can access the guidance information DB 44E, read the guidance information corresponding to the alarm, and display it in a different area of the display screen.

進而，若操作員雙擊(選擇)顯示於圖表推薦列表GL1之預定的圖表GR1，則訪問圖表設定DB44C的同時取得製程資料，並顯示該圖表。在相同的顯示畫面的第3區域AR3顯示由操作員選擇的圖表(例如，“循環系統溫度差1”)。Furthermore, when the operator double-clicks (selects) a predetermined chart GR1 displayed in the chart recommendation list GL1, the chart setting DB 44C is accessed and process data is acquired, and the chart is displayed. The graph (for example, "circulation system temperature difference 1") selected by the operator is displayed in the third area AR3 of the same display screen.

若操作員雙擊(選擇)顯示於圖表推薦列表GL1之其他圖表，則在相同的顯示畫面的第3區域AR3顯示由操作員選擇的不同的圖表(例如，“循環系統壓力差1”)。另外，可以構成為在第3區域AR3能夠同時顯示複數個圖表。When the operator double-clicks (selects) another graph displayed in the graph recommendation list GL1, a different graph (for example, "circulation system pressure difference 1") selected by the operator is displayed in the third area AR3 of the same display screen. In addition, a plurality of graphs may be simultaneously displayed in the third area AR3.

圖表顯示實績收集部42E(“記錄機構”的一例)在操作員選擇顯示於圖表推薦列表GL1之圖表時，將在發出該警報時閱覽了該圖表之資訊記錄於圖表閲覧歷程DB44D。本實施形態中，與該警報建立關聯地計數該圖表的閲覧次數。When the operator selects a graph displayed in the graph recommendation list GL1, the graph display record collection unit 42E (an example of the "recording means") records the information that the graph was viewed when the alarm was issued in the graph reading history DB 44D. In this embodiment, the number of times of viewing the graph is counted in association with the alarm.

圖6係表示用以實現本實施形態之運轉支援系統30的物理結構之圖。然而，邊緣/雲端運算部32能夠採用習知之物理結構，因此省略說明，以下對除了邊緣/雲端運算部32以外的運轉支援系統30的物理結構進行說明。FIG. 6 is a diagram showing the physical configuration of the operation support system 30 for realizing the present embodiment. However, the edge/cloud computing unit 32 can adopt a known physical structure, so the description is omitted, and the physical structure of the operation support system 30 other than the edge/cloud computing unit 32 will be described below.

運轉支援系統30具有相當於演算部之CPU (Central Processing Unit：中央處理單元)30A、相當於記憶部之RAM(Random Access Memory：隨機存取記憶體)30B及ROM (Read only Memory：唯讀記憶體)30C、通訊部30D、輸入部30E、顯示部30F。該等各結構透過匯流排以能夠相互發送/接收資料的方式連接。另外，本例中，運轉支援系統30由一台電腦構成之情況進行了說明，但運轉支援系統30可以由複數台電腦構成。例如，顯示部30F可以由複數台顯示器構成。又，圖6所示之結構僅為一例，可以不具有該等結構中的一部分。進而，結構的一部分可以設置於偏遠地區。例如，亦可以構成為將ROM30C的一部分設置於偏遠地區，透過通訊網路能夠通訊。The operation support system 30 includes a CPU (Central Processing Unit) 30A corresponding to an arithmetic unit, a RAM (Random Access Memory) 30B corresponding to a memory unit, and a ROM (Read only Memory) body) 30C, a communication unit 30D, an input unit 30E, and a display unit 30F. These structures are connected by bus bars in such a way that they can send/receive data to each other. In addition, in this example, although the case where the operation support system 30 is comprised by a single computer was demonstrated, the operation support system 30 may be comprised by several computers. For example, the display unit 30F may be constituted by a plurality of displays. In addition, the structure shown in FIG. 6 is only an example, and it is not necessary to have some of these structures. Furthermore, part of the structure can be located in remote areas. For example, a part of the ROM 30C may be installed in a remote area, and communication may be possible through a communication network.

CPU30A係藉由執行記錄於ROM30C等之電腦程式等，進行本發明所包括之控制處理及演算處理等之演算部。CPU30A具備處理器。CPU30A從RAM30B、ROM30C、通訊部30D及輸入部30E等接收各種資訊(包括製程資料)，使演算處理結果等顯示於顯示部30F或儲存於RAM30B或ROM30C。The CPU 30A is an arithmetic unit that executes control processing, arithmetic processing, and the like included in the present invention by executing a computer program or the like recorded in the ROM 30C or the like. The CPU 30A includes a processor. The CPU 30A receives various information (including process data) from the RAM 30B, the ROM 30C, the communication unit 30D, the input unit 30E, etc., and displays the calculation processing results on the display unit 30F or stores them in the RAM 30B or ROM 30C.

RAM30B在記憶部中作為快取記憶體發揮作用，例如可以由SRAM及DRAM等揮發性半導體記憶元件。The RAM 30B functions as a cache memory in the memory portion, and can be a volatile semiconductor memory element such as SRAM and DRAM, for example.

ROM30C在記憶部中作為主記憶體發揮作用，例如可以由快閃記憶體等能夠電改寫資訊之非揮發性半導體記憶元件或能夠磁改寫資訊之HDD構成。例如，ROM30C可以儲存用以執行包括本發明所示之各控制及各演算處理之處理的電腦程式及資料。The ROM 30C functions as a main memory in the memory section, and may be formed of, for example, a flash memory or a non-volatile semiconductor memory element capable of electrically rewriting information, or an HDD capable of magnetically rewriting information. For example, the ROM 30C can store computer programs and data for executing the processing including each control and each arithmetic processing shown in the present invention.

通訊部30D係用以使運轉支援系統30與DCS20等其他裝置連接的介面。通訊部30D可以連接於網際網路等通訊網路。The communication unit 30D is an interface for connecting the operation support system 30 with other devices such as the DCS 20 . The communication unit 30D can be connected to a communication network such as the Internet.

輸入部30E從操作員接受資料的輸入及圖表的選擇等，例如可以包括鍵盤及觸控面板。The input unit 30E accepts input of data, selection of graphs, and the like from the operator, and may include, for example, a keyboard and a touch panel.

顯示部30F視覺顯示基於CPU30A之演算結果，例如由LCD(Liquid Crystal Display：液晶顯示器)構成。The display part 30F visually displays the calculation result based on CPU30A, and is comprised by LCD (Liquid Crystal Display: liquid crystal display), for example.

在上述物理結構中，藉由主要由CPU30A執行電腦程式，能夠實現構成監視裝置40的警報顯示控制部42之各功能，能夠主要由ROM30C實現構成記憶部44之各資料庫，能夠主要由顯示部30F實現顯示裝置50。In the above-mentioned physical structure, the functions of the alarm display control unit 42 constituting the monitoring device 40 can be realized by mainly executing the computer program by the CPU 30A, the respective databases constituting the memory unit 44 can be realized mainly by the ROM 30C, and the display unit can be realized mainly by the ROM 30C. 30F implements the display device 50 .

[顯示方法]以下，對用以追蹤使用運轉支援系統30向操作員發出的警報的妥當性之資訊的顯示方法進行說明。圖7係包括此類顯示方法之流程圖。[Display method] Hereinafter, a display method of information for tracking the validity of the alarm issued to the operator using the operation support system 30 will be described. FIG. 7 is a flowchart including such a display method.

首先，警報判定部42B根據警報判定邏輯評價藉由製程資料取得部42A取得之製程資料，判斷工廠1是否發生了異常。若警報判定部42B判斷為工廠1發生了預定的異常，則發出警報(步驟S71)。具體而言，監視裝置40使顯示畫面的第1區域AR1以列表形式顯示從警報判定部42B取得之與過去及當前的警報有關之資訊。另外，監視裝置40使顯示畫面的第2區域AR2顯示與最新警報對應之圖表推薦列表，使第3區域AR3顯示該圖表推薦列表的得分值最大的複數個圖表，進而使其他區域顯示與最新警報對應之導引資訊。First, the alarm determination unit 42B evaluates the process data acquired by the process data acquisition unit 42A according to the alarm determination logic, and determines whether or not an abnormality has occurred in the factory 1 . When the alarm determination unit 42B determines that a predetermined abnormality has occurred in the factory 1, an alarm is issued (step S71). Specifically, the monitoring device 40 causes the first area AR1 of the display screen to display the information on past and current alarms acquired from the alarm determination unit 42B in a list format. In addition, the monitoring device 40 displays the chart recommendation list corresponding to the latest alarm in the second area AR2 of the display screen, displays a plurality of charts with the highest score value in the chart recommendation list in the third area AR3, and displays the charts with the latest alerts in the other areas. The guidance information corresponding to the alert.

發出警報時，操作員開始確認該警報的妥當性之作業。具體而言，操作員仔細考慮在圖表推薦列表中列出之圖表名、訊號名及其得分值(圖4)的同時選擇應確認的圖表(步驟S72)。另外，操作員在選擇了顯示於第1區域AR1之其他警報時，監視裝置40使顯示畫面的第2區域AR2顯示與該警報對應之圖表推薦列表，使第3區域AR3顯示對應之圖表，進而使其他區域顯示導引資訊。When an alarm is issued, the operator starts the work of confirming the validity of the alarm. Specifically, the operator selects the chart to be confirmed (step S72 ) while carefully considering the chart names, signal names and their score values ( FIG. 4 ) listed in the chart recommendation list. In addition, when the operator selects another alarm displayed in the first area AR1, the monitoring device 40 displays a chart recommendation list corresponding to the alarm in the second area AR2 of the display screen, displays the corresponding chart in the third area AR3, and further Make other areas display navigation information.

在此，圖表推薦列表中包括得分值。因此，操作員能夠掌握應確認的優先度高的圖表。又，得分值不是預先設定的值，而是反映了在工廠1的運轉中實際由操作員閲覧的事實之資訊。即使為相同警報，若工廠不同，則本實施形態之圖表推薦列表有可能不同。因此，操作員根據搭載於工廠1之機種特有的觀點，能夠掌握應確認的優先度高的圖表。Here, the score value is included in the chart recommendation list. Therefore, the operator can grasp the high-priority graph to be checked. In addition, the score value is not a preset value, but information reflecting the fact that the operator actually sees it during the operation of the factory 1 . Even if it is the same alarm, if the factory is different, the chart recommendation list of this embodiment may be different. Therefore, the operator can grasp the high-priority graph to be checked from the viewpoint peculiar to the model mounted on the plant 1 .

進而，圖表推薦列表反映了在工廠1運轉時實際由操作員閲覧的事實，因此根據經時變化等，例如即使為相同工廠，針對相同的警報亦有可能成為不同的圖表推薦列表。因此，操作員根據考慮了工廠1的經時變化等的觀點，能夠掌握應確認的優先度高的圖表。Furthermore, the graph recommendation list reflects the fact that the operator actually reads it while the factory 1 is operating. Therefore, depending on changes over time, for example, even in the same factory, there may be a different graph recommendation list for the same alarm. Therefore, the operator can grasp the high-priority graph that should be checked from the viewpoint of taking into consideration changes over time in the plant 1 and the like.

若操作員從作為圖表推薦列表顯示之圖表的選項中選擇一個圖表，則監視裝置40使顯示畫面的第3區域AR2顯示所選擇的圖表(步驟S73)。When the operator selects one chart from the options of charts displayed as the chart recommendation list, the monitoring device 40 displays the selected chart in the third area AR2 of the display screen (step S73).

操作員能夠根據情況，以認為合適的順序靈活地選擇圖表。例如，亦能夠優先選擇並顯示得分值低的圖表之後，選擇並顯示得分值高的圖表。如此，能夠將得分值低的圖表的閲覧結果作為前提，閱覽得分高的圖表。Operators have the flexibility to select charts in the order they see fit, depending on the situation. For example, it is also possible to select and display a graph with a high score value after preferentially selecting and displaying a graph with a low score value. In this way, it is possible to view a graph with a high score on the premise of the viewing result of a graph with a low score value.

在操作員選擇顯示於圖表推薦列表之圖表時，監視裝置40將發出該警報時閱覽了該圖表之資訊記錄於圖表閲覧歷程DB44D(步驟S74)。When the operator selects a chart displayed in the chart recommendation list, the monitoring device 40 records in the chart reading history DB 44D the information that the chart was viewed when the alarm was issued (step S74).

操作員在使應確認的圖表全部顯示而確認發出警報的妥當性之後，進行遵照導引資訊之對應。The operator displays all the graphs to be checked and confirms the validity of the alarm, and then responds according to the guidance information.

如上所述，藉由本實施形態所示之顯示裝置及顯示方法，能夠有效地確認應確認的圖表。As described above, with the display device and the display method shown in this embodiment, the graph to be checked can be checked efficiently.

[變形例] 本發明只要不脫離其主旨，則能夠進行各種變形。例如，亦可以構成為如下：根據操作員選擇並顯示於顯示畫面之圖表的閲覧歷程，藉由習知之協同過濾演算法學習圖表間的類似度，根據類似度算出得分值。此時，圖表推薦順序算出部42C根據所有操作員的圖表的閲覧歷程，機器學習圖表間的類似度，根據該類似度算出得分值並記錄於圖表閲覧歷程DB。例如，類似度可以使用歐幾里得距離、加權平均或皮爾森係數等算出。又，亦可以根據顯示中的圖表，更新圖表推薦列表。另外，圖表推薦順序算出部42C可以根據使用過去發生的警告和該警告時閱覽之圖表的歷程作為教師資料來生成的學習模型，算出得分值。機器學習模型包括使用卷積類神經網路(CNN)等類神經網路之模型、使用高斯過程回歸等回歸模型之模型、使用決策樹等樹演算法之模型。在收集用以機器學習的資訊時，能夠使用邊緣/雲端運算部32。 [Variation] Various modifications can be made to the present invention without departing from the gist of the present invention. For example, it may be structured as follows: based on the viewing history of the graphs selected by the operator and displayed on the display screen, the similarity between the graphs is learned by a conventional collaborative filtering algorithm, and the score value is calculated based on the similarity. At this time, the chart recommendation order calculation unit 42C learns the similarity between the charts based on the viewing history of the charts of all operators, and calculates a score value based on the similarity, and records it in the chart viewing history DB. For example, the similarity can be calculated using Euclidean distance, weighted average, Pearson coefficient, or the like. Also, the graph recommendation list may be updated based on the graph being displayed. In addition, the chart recommendation order calculation unit 42C may calculate the score value based on the learning model generated using the history of warnings that occurred in the past and the charts viewed at the time of the warnings as teacher data. Machine learning models include models using neural networks such as convolutional neural networks (CNN), models using regression models such as Gaussian process regression, and models using tree algorithms such as decision trees. When collecting information for machine learning, the edge/cloud computing unit 32 can be used.

又，圖表推薦列表可以僅顯示得分值高的內容，亦可以顯示所有具有得分值的內容。在特殊情況下，亦存在需要閱覽得分值低的圖表的情況。In addition, the chart recommendation list may display only content with a high score value, or may display all content with a score value. In special cases, there are also cases where it is necessary to view graphs with low score values.
