[0012] Embodiment 1 An example of the configuration of a remote monitoring device 10 according to the present disclosure will be described below with reference to FIG. 1. The remote monitoring device 10 is capable of communicating with a facility device to be monitored and a user terminal used by a user, and the user monitors the facility device via the remote monitoring device 10. The facility device to be monitored may be, for example, a device installed in a sewage treatment plant, a factory, a water gate, a building, or the like, and is not particularly limited. Examples of the user terminal include a personal computer, tablet terminal, smartphone, telephone, or the like used by the user. The remote monitoring device 10 is communicably connected to the facility device and the user terminal via a network such as the Internet or an analog line. As shown in FIG. 1, the remote monitoring device 10 includes an acquisition unit 11, a creation unit 12, and a display control unit 13.

[0013] The acquisition unit 11 acquires, from the facility equipment to be monitored, multiple types of data that contribute to the monitoring of the facility equipment. For example, the acquisition unit 11 acquires analog data from the facility equipment. Here, analog data includes, for example, detection values ​​of various sensors provided in the facility equipment, such as current values. More specifically, the analog data is data input to an analog input terminal of the remote monitoring device 10, and the acquisition unit 11 may acquire the detection values ​​of the various sensors as continuous numerical values ​​(analog values), for example, from 0 to 4095. The acquisition unit 11 may also convert the acquired detection values ​​or analog values ​​into specific physical quantities such as water level, flow rate, position, and distance. The acquisition unit 11 may also acquire the analog data at a predetermined timing, such as 1:00 PM every day, or may acquire the analog data sequentially. The analog data acquired by the acquisition unit 11 may also be stored in a storage unit (not shown).

[0014] The creation unit 12 selects two or more types of analog data for a predetermined period from the multiple types of analog data acquired by the acquisition unit 11. The creation unit 12 also creates a scatter plot in which the two or more types of analog data selected are plotted on a graph having a Y axis and an X axis representing the two or more types of analog data. Specifically, when two types of analog data are selected, the creation unit 12 plots the two types of analog data detected at the same or corresponding timing as one point on a graph having a Y axis representing one of the analog data and an X axis representing the other analog data. Furthermore, when four types of analog data, for example, first to fourth analog data, are selected, the creation unit 12 plots the four types of analog data detected at the same or corresponding timing as one point on a graph having a Y-axis representing a relational equation (hereinafter also referred to as the "Y-axis calculation formula") that represents the relationship between the first analog data and the second analog data, and an X-axis representing a relational equation (hereinafter also referred to as the "X-axis calculation formula") that represents the relationship between the third analog data and the fourth analog data. Furthermore, when four types of analog data, for example, the first to fourth analog data, are selected, the creation unit 12 may plot the four types of analog data detected at the same or corresponding timing as one point on a graph having a Y-axis representing a Y-axis calculation formula that expresses the relationship between the first to third analog data and an X-axis representing an X-axis calculation formula that expresses the relationship between the second to fourth analog data. In other words, the analog data used to calculate the Y-axis calculation formula and the analog data used to calculate the X-axis calculation formula may partially overlap. Then, the creation unit 12 creates a scatter diagram by plotting points for the two or more types of analog data for the selected predetermined period. The scatter diagram created by the creation unit 12 may be stored in a storage unit (not shown).

[0015] The display control unit 13 divides the scatter diagram created by the creation unit 12 into m×n regions (m and n are positive integers). The display control unit 13 also displays the scatter diagram on a display unit (not shown) so that the user can fill each region with either a color indicating an abnormal region or a color indicating a normal region. Here, the normal region is a region in which points representing two or more types of analog data are plotted when the relationship between the analog data is a relationship that can be satisfied when the facility equipment is in a normal operating state. The abnormal region is a region other than the normal region. Note that m and n may be different integers or the same integer. The display unit (not shown) on which the display control unit 13 displays the scatter diagram may be the display unit of the remote monitoring device 10 or the display unit of a user terminal. When the display control unit 13 displays the scatter diagram on the display unit of the user terminal, the display control unit 13 transmits data of the scatter diagram to the user terminal.

[0016] 2 is a flowchart showing an example of a remote monitoring method according to the present disclosure. First, the acquisition unit 11 acquires multiple types of analog data from facility equipment (step S11). Next, the creation unit 12 selects two or more types of analog data from the multiple types of analog data acquired by the acquisition unit 11 and creates a scatter plot (step S12). Next, the display control unit 13 divides the scatter plot into m×n regions and displays it on a display unit (not shown) so that each region can be colored in either a color indicating an abnormal region or a color indicating a normal region (step S13), and this process ends.

[0017] In the remote monitoring device 10 according to the present disclosure, the scatter plot is divided into m×n regions, and is displayed on a display unit (not shown) so that each region can be filled in with either a color indicating an abnormal region or a color indicating a normal region. This allows the user to set the abnormal region and the normal region more flexibly. This makes it possible to provide a remote monitoring device 10 that can monitor facility equipment more flexibly.

[0018] Embodiment 2 Next, an example of the configuration of a remote monitoring system 100 according to the present disclosure will be described with reference to Fig. 3. The remote monitoring system 100 includes one or more facility devices 200_1, 200_2, ..., 200_i (hereinafter, when the facility devices 200_1, 200_2, ..., 200_i are not particularly distinguished from one another, they will be simply referred to as "facility devices 200"), one or more user terminals 300_1, 300_2, ..., 300_j (hereinafter, when the user terminals 300_1, 300_2, ..., 300_j are not particularly distinguished from one another, they will be simply referred to as "user terminals 300"), and a remote monitoring device 400 capable of communicating with the facility devices 200 and the user terminals 300 via a network N.

[0019] Next, an example of the configuration of facility device 200 according to the present disclosure will be described with reference to Fig. 4. As shown in Fig. 4, facility device 200 includes a storage unit 210, a memory 220, a communication unit 230, an output unit 240, a sensor 250, and a control unit 260.

[0020] The storage unit 210 is a storage device that stores a program 211 for implementing each function of the facility device 200. The storage unit 210 also stores an application 212 that enables the facility device 200 to perform processes necessary for the remote monitoring device 400 to monitor the facility device 200, such as a process for transmitting analog data to the remote monitoring device 400. The memory 220 is a volatile storage device such as RAM, and is a storage area for temporarily storing information when the control unit 260 is operating. The communication unit 230 is a communication interface with the network.

[0021] The output unit 240 outputs the information processing result of the control unit 260. For example, the output unit 240 has a display unit 241 and an audio output unit 242. The display unit 241 is a display device that displays the information processing result of the control unit 260. Note that the facility device 200 may be provided with an input unit (not shown) that accepts input, and the display unit 241 and the input unit may be integrally configured like a touch panel. The audio output unit 242 includes a speaker (not shown) and outputs the information processing result of the control unit 260 by audio.

[0022] The sensor 250 detects analog data for monitoring the operation of the facility device 200, such as a water level meter, a flow meter, a pressure meter, a distance sensor, etc.

[0023] The control unit 260 is a processor, i.e., a control device, that controls each component of the facility device 200. The control unit 260 loads the program 211 from the storage unit 210 into the memory 220 and executes the program 211. In this way, the control unit 260 realizes the function of the output control unit 261. The control unit 260 also loads the application 212 from the storage unit 210 into the memory 220 and executes the application 212. In this way, the control unit 260 transmits analog data, which is a detection value of the sensor 250, to the remote monitoring device 400. In addition, the control unit 260 also performs various other processes necessary for the remote monitoring device 400 to monitor the facility device 200.

[0024] The output control unit 261 controls the output unit 240 and causes the output unit 240 to output the information processing result. For example, the output control unit 261 causes the display unit 241 to display information related to the operating state of the facility device 200. In addition, the output control unit 261 causes the audio output unit 242 to output audio based on the information processing result.

[0025] Next, an example of the configuration of a user terminal 300 according to the present disclosure will be described with reference to Fig. 5. As shown in Fig. 5, the user terminal 300 includes a storage unit 310, a memory 320, a communication unit 330, an output unit 340, and a control unit 350.

[0026] The storage unit 310 is a storage device that stores a program 311 for implementing each function of the user terminal 300. The storage unit 310 also stores an application 312 for performing processing for monitoring the facility device 200 via the remote monitoring device 400. The memory 320 is a volatile storage device such as RAM, and is a storage area for temporarily storing information when the control unit 350 is operating. The communication unit 330 is a communication interface with the network.

[0027] The output unit 340 outputs the information processing result of the control unit 350. For example, the output unit 340 has a display unit 341 and an audio output unit 342. The display unit 341 is a display device that displays the information processing result of the control unit 350. The user terminal 300 may also include an input unit (not shown) that accepts input, and the display unit 341 and the input unit may be integrated into one unit, such as a touch panel. The audio output unit 342 includes a speaker (not shown) and outputs the information processing result of the control unit 350 as audio.

[0028] The control unit 350 is a processor, i.e., a control device, that controls each component of the user terminal 300. The control unit 350 loads the program 311 from the storage unit 310 into the memory 320 and executes the program 311. In this way, the control unit 350 realizes the function of the output control unit 351. The control unit 350 also loads the application 312 from the storage unit 310 into the memory 320 and executes the application 312. In this way, the control unit 350 performs various processes for monitoring the facility device 200 via the remote monitoring device 400.

[0029] The output control unit 351 controls the output unit 340 to cause the output unit 340 to output the information processing result. For example, the output control unit 351 causes the display unit 341 to display a scatter diagram transmitted from the remote monitoring device 400. Furthermore, when a predetermined notification is transmitted from the remote monitoring device 400, the output control unit 351 may cause the display unit 341 to display the notification. Furthermore, when a predetermined notification is transmitted from the remote monitoring device 400, the output control unit 351 may cause the audio output unit 342 to output audio based on the notification.

[0030] 6 shows an example of the configuration of the remote monitoring device 400. The remote monitoring device 400 includes a storage unit 410, a memory 420, a communication unit 430, an output unit 440, and a control unit 450.

[0031] The storage unit 410 is a storage device that stores a program 411 for realizing each function of the remote monitoring device 400. The storage unit 410 also stores an analog data table 412, X / Y axis calculation formula information 413, scatter diagram data 414, etc. The memory 420 is a volatile storage device such as RAM, and is a storage area for temporarily holding information when the control unit 450 is operating. The communication unit 430 is a communication interface with the network.

[0032] Fig. 7 shows an example of the analog data table 412. As shown in Fig. 7, the analog data table 412 is information in which identification information 412A, detection date and time 412B, analog value 412C, and conversion value 412D are associated with each other. The identification information 412A is identification information for identifying the type of analog data. Detection values ​​detected by different sensors 250 constitute different types of analog data. The identification information 412A may also include identification information of the facility device 200. Detection date and time 412B is the date and time when the detection value included in the analog data identified by identification information 412A was detected. Detection date and time 412B is transmitted from facility device 200 to remote monitoring device 400 as analog data together with the detection value. Analog value 412C is a detection value detected by sensor 250 of facility device 200. Note that analog value 412C may be the detection value itself of various sensors, or may be a continuous numerical value (analog value) such as 0 to 4095 that represents the detection value. The converted value 412D is a value that represents a specific physical quantity such as a water level, a flow rate, a position, or a distance, converted from the detected value or analog value.

[0033] The X / Y-axis calculation formula information 413 is information in which the identification information of the scatter plot is associated with the X-axis calculation formula and the Y-axis calculation formula. The X-axis calculation formula and the Y-axis calculation formula are determined in advance by the user and stored as the X / Y-axis calculation formula information 413 in the storage unit 410.

[0034] The scatter diagram data 414 is information in which a scatter diagram created by the creation unit 453 is associated with identification information for identifying the scatter diagram. Furthermore, when a user sets an abnormal region and a normal region in a scatter diagram displayed by the display unit 441, the storage unit 410 associates the scatter diagram in which the abnormal region and the normal region are set as an updated scatter diagram with the identification information and stores the scatter diagram data 414. Alternatively, the storage unit 410 may associate the scatter diagram in which the abnormal region and the normal region are set with the scatter diagram and identification information before the abnormal region and the normal region were set and store the scatter diagram data 414.

[0035] The output unit 440 outputs the information processing result of the control unit 450. For example, the output unit 440 has a display unit 441 and an audio output unit 442. The display unit 441 is a display device that displays the information processing result of the control unit 450. The remote monitoring device 400 may be provided with an input unit (not shown) that accepts input, and the display unit 441 and the input unit may be integrally configured like a touch panel. The audio output unit 442 includes a speaker (not shown) and outputs the information processing result of the control unit 350 as audio.

[0036] The control unit 450 is a processor, i.e., a control device, that controls each component of the remote monitoring device 400. The control unit 450 loads the program 411 from the storage unit 410 into the memory 420 and executes the program 411. In this way, the control unit 450 realizes the functions of an acquisition unit 451, a storage control unit 452, a creation unit 453, an output control unit 454, a plot unit 455, and a notification unit 456.

[0037] The acquisition unit 451 acquires, from the facility device to be monitored, multiple types of analog data that contribute to monitoring the facility device. The acquisition unit 451 may acquire the detection value of the sensor 250 of the facility device 200 as a continuous numerical value (analog value) such as 0 to 4095. The acquisition unit 451 may also convert the acquired detection value or analog value into a specific physical quantity such as a water level, a flow rate, a position, or a distance. The acquisition unit 451 may acquire the analog data at a predetermined timing, or may acquire the analog data sequentially.

[0038] The storage control unit 452 controls the storage unit 410 to store the analog data acquired by the acquisition unit 451 in the analog data table 412. The storage control unit 452 controls the storage unit 410 to associate the Y-axis calculation formula and the X-axis calculation formula determined by the user and store them in X / Y-axis calculation formula information 413. The storage control unit 452 also controls the storage unit 410 to associate the scatter diagram created by the creation unit 453 with identification information and store them in scatter diagram data 414.

[0039] The creation unit 453 selects two or more types of analog data for a predetermined period from the multiple types of analog data acquired by the acquisition unit 451. The creation unit 453 also creates a scatter plot in which the two or more types of analog data selected are plotted on a graph having a Y axis and an X axis representing the two or more types of analog data. Specifically, the creation unit 453 references the X / Y-axis calculation formula information 413 and acquires the X-axis calculation formula and the Y-axis calculation formula corresponding to the identification information of the scatter diagram to be created. Next, the creation unit 453 determines the minimum and maximum values ​​of the X-axis and the minimum and maximum values ​​of the Y-axis. Note that the minimum and maximum values ​​of the X-axis and the minimum and maximum values ​​of the Y-axis may be determined based on the detectable range of the sensor 250, based on data already stored in the analog data table 412 of the storage unit 410, or may be determined in advance by a user who has experience monitoring the facility equipment. Next, the creation unit 453 calculates the X-coordinate and the Y-coordinate based on the selected multiple types of analog data and the acquired X-axis and Y-axis calculation formulas. Next, the creation unit 453 plots points having the calculated X-coordinates and Y-coordinates on a graph. The creation unit 453 then creates a scatter diagram by plotting points for two or more types of analog data for the selected predetermined period.

[0040] The output control unit 454 divides the scatter diagram created by the creation unit 453 into m×n (m and n are positive integers) regions. The output control unit 454 also displays the scatter diagram on the display unit 341 of the user terminal 300 so that the user can fill each region with either a color indicating an abnormal region or a color indicating a normal region. Specifically, the output control unit 454 transmits data of the scatter diagram to the user terminal 300. Note that m and n may be different integers or may be the same integer. The output control unit 454 may also display the scatter diagram on the display unit 441 of the remote monitoring device 400.

[0041] Furthermore, the output control unit 454 may determine a relational expression that represents the correlation between the Y coordinate and the X coordinate of each point in the scatter diagram created by the creation unit 453, and may cause the display unit 341 to display the scatter diagram in a state in which each region of the scatter diagram is painted in advance with either a color indicating an abnormal region or a color indicating a normal region based on the relational expression. Specifically, if the relational expression is, for example, an approximate curve, the output control unit 454 may cause the display unit 341 to display a scatter diagram in a state in which a region of a predetermined width centered on the approximate curve is painted in a color indicating a normal region, and the region other than the approximate curve is painted in a color indicating an abnormal region.

[0042] The plotting unit 455 plots points represented by Y coordinates and X coordinates based on the two or more types of analog data newly acquired by the acquiring unit 451. Specifically, the plotting unit 455 calculates the coordinates of the points representing the two or more types of analog data using the same method as the creating unit 453, and plots the points on the scatter diagram created by the creating unit 453. Furthermore, when a point representing the two or more types of analog data is located outside the range divided into m×n regions, the plotting unit 455 creates a scatter plot by changing the minimum and maximum values ​​on the X-axis and the minimum and maximum values ​​on the Y-axis, and plots the point outside the range divided into m×n regions. The plotting unit 455 also divides the area outside the range divided into m×n regions into areas of the same size as the area. The plotting unit 455 also displays a scatter plot on the display unit 341, with each divided area outside the range painted in advance with either a color indicating an abnormal area or a color indicating a normal area. In this case, the user has previously determined whether each area outside the range divided into m×n regions is an abnormal area or a normal area.

[0043] The notification unit 456 notifies the user when the point plotted by the plotting unit 455 is in an abnormal region. Specifically, when the coordinates of the point calculated by the plotting unit 455 match the coordinates of the abnormal region, the notification unit 456 transmits to the user terminal 300 a predetermined notification indicating that an abnormality has been detected. Furthermore, the notification unit 456 may notify the user when the plotting unit 455 plots points in the abnormal region a predetermined number of times in succession. Furthermore, the notification unit 456 may notify the user when the creation unit 453 creates a plurality of scatter plots and the plot unit 455 plots points in abnormal regions in the plurality of scatter plots.

[0044] Next, an example of a remote monitoring method according to the present disclosure will be described with reference to FIGS. 8 and 9. First, a scatter diagram creation process in the remote monitoring method according to the present disclosure will be described with reference to FIG. 8. First, the acquisition unit 451 acquires multiple types of analog data from the facility device 200 (step S101). Next, the memory control unit 452 stores the analog data acquired by the acquisition unit 451 in the analog data table 412 in the memory unit 410 (step S102). Next, the creation unit 453 selects two or more types of analog data for a predetermined period from the multiple types of analog data acquired by the acquisition unit 451, and calculates the X coordinates and Y coordinates of points representing the analog data based on the analog data and the X-axis calculation formula and the Y-axis calculation formula (step S103). Next, the creation unit 453 creates a scatter diagram by plotting points for the selected two or more types of analog data for the predetermined period (step S104). Next, the display control unit 13 divides the scatter diagram into m×n regions and displays the scatter diagram on the display unit 341 of the user terminal 300 so that each region can be filled in with either a color indicating an abnormal region or a color indicating a normal region (step S105). Next, the user operates the display unit 341 of the user terminal 300 to set an abnormal region in the scatter diagram (step S106). Next, the storage control unit 452 stores the scatter diagram in which the abnormal region has been set as an updated scatter diagram in the storage unit 410 in association with the identification information, and in the scatter diagram data 414 (step S107), and this process ends.

[0045] Next, the monitoring process of the remote monitoring method according to the present disclosure will be described with reference to FIG. 9. First, the acquisition unit 451 acquires new types of analog data from the facility device 200 (step S201). Next, the plotting unit 455 plots points representing the new analog data on the scatter diagram created in the scatter diagram creation process shown in FIG. 8 (step S202). Next, if the plotting unit 455 plots the points in a normal region of the scatter diagram (step S203; No), this process ends. On the other hand, if the plotting unit 455 plots the points in an abnormal region of the scatter diagram (step S203; Yes), the notification unit 456 transmits a predetermined notification indicating that an abnormality has been detected to the user terminal 300 (step S204), and this process ends.

[0046] FIG. 10 shows an example of a screen of the display unit 341 displaying a scatter diagram. In the example shown in FIG. 10, the scatter diagram is divided into 24×24 regions. Furthermore, in FIG. 10, abnormal regions are indicated by hatching, and normal regions are indicated by no hatching. In other words, in the scatter diagram shown in FIG. 10, abnormal regions are colored, and normal regions are not colored. Furthermore, in the scatter diagram shown in FIG. 10, points plotted in normal regions are indicated by black circles, and points plotted in abnormal regions are indicated by white circles. In this way, by viewing the scatter diagram displayed on the display unit 341 of the user terminal 300, the user can easily determine whether an abnormality has occurred in the facility equipment 200 based on whether a point is plotted in the abnormal region. Furthermore, the notification unit 456 transmits a predetermined notification indicating that an abnormality has been detected to the user terminal 300, and the output unit 340 of the user terminal 300 displays or outputs the notification as sound. This allows the user to quickly recognize that an abnormality has occurred in the facility equipment 200. 10, the screen of display unit 341 displays, below the scatter plot, an "all clear" icon for clearing the color of all areas in the scatter plot, a "full fill" icon for coloring all areas in the scatter plot, an "eraser" icon for clearing the color of each area, a "thickness" icon for setting the number of areas to be colored, and a "data display" icon for setting whether or not to display points plotted on the scatter plot. By operating these icons, the user can flexibly and freely set abnormal and normal areas in the scatter plot.

[0047] Example 1 Next, one embodiment to which the remote monitoring system according to the present disclosure is applied will be described with reference to Figures 11 and 12. In the embodiment 1 shown in Figure 11, facility equipment 200 includes a cooling tower 501, a chiller 502, and air conditioning equipment 503. Cooling tower 501 supplies cooling water to refrigerant 502A of chiller 502, and the water heated by cooling refrigerant 502A from chiller 502 is returned to cooling tower 501. Meanwhile, water heated by air conditioning in air conditioning equipment 503 is supplied from air conditioning equipment 503 to refrigerant 502A of chiller 502, and the water cooled by refrigerant 502A from chiller 502 is returned to air conditioning equipment 503. The first sensor 504 detects the temperature of water supplied from the cooling tower 501 to the chiller 502, the second sensor 505 detects the temperature of water returning from the chiller 502 to the cooling tower 501, the third sensor 506 detects the temperature of water supplied from the air conditioning equipment 503 to the chiller 502, and the fourth sensor 507 detects the temperature of water returning from the chiller 502 to the air conditioning equipment 503.

[0048] 12 shows an example of a scatter diagram created by the creation unit 453 and displayed on the display unit 341 of the user terminal 300 by the output control unit 454 to monitor the facility device 200 of the first embodiment. In the example shown in FIG. 12, the X-axis represents temperature difference A, which is the difference between the temperatures detected by the first sensor 504 and the second sensor 505, and the Y-axis represents temperature difference B, which is the difference between the temperatures detected by the third sensor 506 and the fourth sensor 507. In the normal region, temperature difference A is approximately equal to temperature difference B. In the abnormal region in the upper left of the scatter diagram, temperature difference A is less than temperature difference B. In the abnormal region in the lower right of the scatter diagram, temperature difference A is greater than temperature difference B. When the plot unit 455 plots a point in the abnormal region in the upper left of the scatter diagram, the user can consider the possibility that the cooling piping for refrigerant 502A is dirty, causing a decrease in efficiency, for example. Furthermore, if the plotting unit 455 plots a point in the abnormal region at the bottom right of the scatter plot, the user can consider, for example, the possibility that the cooling pipes of the air conditioning equipment 503 are dirty, causing a deterioration in efficiency.

[0049] The acquiring unit 451 may acquire digital data in addition to analog data. Here, the digital data includes detection values ​​of various sensors 250 provided in the facility equipment 200 and is data input to a digital input terminal of the remote monitoring device 400. For example, the digital data may be integrated value data such as time integration data and pulse integration data. The time integration data is the integrated value of the time that a digital input terminal is in an ON state or an OFF state within a certain period of time, and represents, for example, the integrated value of the time that a certain facility equipment 200 was operating or not operating within a certain period of time. Furthermore, the pulse integration data is the integrated value of the number of times that a digital input terminal is switched from an ON state to an OFF state or from an OFF state to an ON state within a certain period of time, and represents, for example, the integrated value of the number of times that a certain facility equipment 200 operated or stopped operating within a certain period of time.

[0050] The creation unit 453 may then create a scatter plot in which the X-axis represents the integrated value (digital data) of the time the pump has been operating within a certain period of time, and the Y-axis represents the water level (analog data). In this example, for example, an abnormal state may be a situation in which the pump is operating for a short period of time despite the water level being high. Therefore, possible conditions for setting the normal region and the abnormal region may be, for example, "if the water level is 5 meters or higher, it is considered normal if the pump has been operating for 1 minute or more," "if the water level is 10 meters or higher, it is considered normal if the pump has been operating for 2 minutes or more," and "anything other than the above is considered abnormal."

[0051] In the remote monitoring system 100 according to the present disclosure, the scatter plot is divided into m×n regions, and is displayed on the display unit 341 of the user terminal 300 so that each region can be filled in with either a color indicating an abnormal region or a color indicating a normal region. This allows the user to set the abnormal region and the normal region more flexibly. This makes it possible to provide a remote monitoring system 100 that can monitor the facility device 200 more flexibly.

[0052] Furthermore, when monitoring facility equipment 200 while taking into account the relationships between multiple types of analog data, it is expected that AI (Artificial Intelligence) technology will be used to detect anomalies based on the multiple types of analog data. However, when using AI technology, it may be difficult to identify the cause of an anomaly. In contrast, in the remote monitoring system 100 according to the present disclosure, the user determines the X-axis calculation formula that defines the X-axis of the scatter diagram and the Y-axis calculation formula that defines the Y-axis. Therefore, the user can predict the cause of an anomaly to some extent by looking at where the points are plotted on the scatter diagram.

[0053] Furthermore, when a point is plotted in an abnormal region of the scatter plot, the notification unit 456 sends a predetermined notification to the user terminal 300 indicating that an abnormality has been detected, so that the user can recognize that an abnormality has been detected at an early stage.

[0054] Furthermore, since the X-axis of the scatter diagram represents the X-coordinate calculated by the X-axis formula, and the Y-axis represents the Y-coordinate calculated by the Y-axis formula, it becomes possible to remotely monitor the facility device 200 using not only two types of analog data but three or more types of analog data, thereby achieving more flexible remote monitoring.

[0055] Furthermore, the output control unit 454 determines a relational expression that represents the correlation between the Y coordinate and X coordinate of each point in the scatter plot, and causes the display unit 341 to display the scatter plot with each area of ​​the scatter plot pre-painted in either a color indicating an abnormal area or a color indicating a normal area based on the relational expression. Therefore, the user can set the abnormal areas and normal areas of the scatter plot simply by correcting the scatter plot in which the abnormal areas and normal areas have already been painted, thereby saving time and effort.

[0056] Furthermore, the notification unit 456 notifies the user when points are plotted consecutively in the abnormal region a predetermined number of times by the plot unit 455. Therefore, when noise occurs in the detection value of the sensor 250 for some reason and the detection value becomes abnormal momentarily, it is possible to prevent the notification unit 456 from notifying the user.

[0057] Furthermore, the notification unit 456 notifies the user when the plotting unit 455 plots a point in an abnormal region in the plurality of scatter diagrams created by the creation unit 453. This makes it possible to realize more flexible monitoring using a plurality of scatter diagrams.

[0058] Furthermore, since the creation unit 453 determines the minimum and maximum values ​​on the X-axis and the minimum and maximum values ​​on the Y-axis of the range divided into m×n regions, the precision with which the abnormal region and normal region are set can be adjusted. For example, if the minimum and maximum values ​​on the X-axis and Y-axis are set to 0°C and 100°C and the range is divided into 100×100, one region corresponds to 1°C. On the other hand, if the minimum and maximum values ​​on the X-axis and Y-axis are set to 0°C and 10°C and the range is divided into 100×100, one region corresponds to 0.1°C. Therefore, by narrowing the range defined by the minimum and maximum values ​​on the X-axis and the minimum and maximum values ​​on the Y-axis, it is possible to set the abnormal region and normal region with greater precision.

[0059] Furthermore, when a point representing two or more types of newly acquired analog data is located outside a range divided into m×n regions, plotting unit 455 plots the point outside the range, divides the outside of the range into regions of the same size as the range, and displays a scatter diagram on display unit 341 with each of the regions outside the range also painted in a color indicating an abnormal region or a normal region. Therefore, even if a point representing two or more types of newly acquired analog data is outside the range divided into m×n regions, it is possible to determine whether the point is normal or abnormal.
