[0011] [Figure 1] Block diagram showing an example of a power system configuration [Figure 2] Schematic overview of the power system [Figure 3] An example of the main management screen [Figure 4] An example of the temperature control screen [Figure 5] An example of the warning list screen DETAILED DESCRIPTION OF THE INVENTION

[0012] <1. Embodiment> FIG. 1 is a block diagram showing an example of the configuration of a power system 500. FIG. 2 is a schematic overall view of the power system 500. The power system 500 of this embodiment is a power generation system that uses a flammable fluid as fuel, is installed indoors or outdoors, and supplies power to external devices and facilities that require power. The power system 500 includes a power unit 100 and an external control device 200.

[0013] <1-1. Power Unit 100> Next, a configuration example of the power unit 100 will be described with reference to Figures 1 and 2. The power unit 100 of the power system 500 includes an engine 101, a generator 102, an ECU (electronic control unit) 104, a management device 103, and a battery 105.

[0014] In this embodiment, the engine 101 is a diesel engine, and drives the generator 102. The engine 101 operates using a mixed fluid of a flammable fluid and air supplied from a turbocharger (not shown) as fuel. The flammable fluid is any one of diesel oil, city gas, propane gas, etc. For example, the engine 101 supplies the mixed fluid to a diesel engine (not shown) and transmits the output thereof to the generator 102.

[0015] The generator 102 is driven by the output transmitted from the engine 101 to generate electricity and supply the electricity to the outside of the power system 500. Note that a portion of the electricity output from the generator 102 can be supplied to the battery 105 and the external control device 200.

[0016] The management device 103 is disposed near the engine 101 and the generator 102, displays the state of the power unit 100, and outputs a signal indicating an operation input to the ECU 10. The management device 103, together with the ECU 104, constitutes a management system 300 that displays measurement values ​​of the power unit 100. In other words, the power unit 100 of the power system 500 is equipped with the management system 300. The management device 103 also relays communication between the external control device 200 and the ECU.

[0017] The management device 103 has a display unit 1031 and an input unit 1032. The display unit 1031 displays measurement results of various measurement targets of the power unit 100 on the display screen 10. In this embodiment, the display unit 1031 is a touch panel and has an operation input function. The display unit 1031 accepts touch inputs of various operation input icons displayed on the display screen 10 by the operation input function, and outputs the operation content of the touch input to the ECU 104. The input unit 1032 is a physical input device that accepts operation inputs from an operator or the like, and outputs an input signal indicating the content of the accepted operation input to the ECU 104. Note that this is not limited to the example of this embodiment, and the input unit 1032 may be omitted. For example, operation inputs may be performed only by the operation input function of the display unit 1031.

[0018] The ECU 104 controls each of the components of the power unit 100 that need to be controlled, using programs and data stored in the memory 1041. The ECU 104 also controls the above-mentioned components of the power unit 100 based on output signals from the external control device 200 and the management device 103, etc.

[0019] The ECU 104 includes a memory 1041 and a display control unit 1042. The memory 1041 is a non-transitory storage medium that maintains its storage even without power supply. The display control unit 1042 controls the display unit 1031.

[0020] The battery 105 is a rechargeable secondary battery such as a lead-acid battery, a lithium-ion battery, or a sodium-sulfur (NAS) battery. Under normal circumstances, the battery 105 receives power from a commercial power grid via the external control device 200 and maintains a fully charged or nearly fully charged state (for example, an 80% charge rate). When the power unit 100 is in operation, the battery 105 may receive a portion of the power output from the generator 102 and maintain a predetermined amount of charge. On the other hand, when a power outage occurs (i.e., when the power supply from the commercial power grid is stopped), the battery 105 supplies the power to components of the power unit 100 that require the power. During a power outage, the battery 105 may also supply power to the external control device 200.

[0021] <1-2. External control device 200> The external control device 200 is disposed outside the power unit 100 and is capable of communicating with the management device 103. As a result, the external control device 200 can control the power unit 100 by cooperating with the ECU 104 via the management device 103. However, the present invention is not limited to this example, and the external control device 200 may be capable of communicating directly with the ECU 104.

[0022] The external control device 200 includes an operation panel 201 , a control unit 202 , and a power supply unit 203 .

[0023] The operation panel 201 has a display unit 2011 and an input unit 2012. The display unit 2011 displays measurement results of various measurement targets of the power unit 100, alarms (notification of abnormal conditions), etc. The input unit 2012 accepts operation inputs from workers or the like and outputs the operation inputs to the control unit 202.

[0024] The control unit 202 controls each of the components that need to be controlled in the external control device 200. The control unit 202 also transmits control signals to the ECU 104, and controls each of the components that need to be controlled in the power unit 100.

[0025] It should be noted that, with regard to operation inputs for controlling the power unit 100, operation inputs at the external control device 200 take priority over operation inputs at the management device 103. In this embodiment, the input unit 2012 has an operation input switching unit. The switching unit selectively enables either operation input at the management device 103 or operation input at the external control device 200. A similar switching unit may also be arranged in the management device 103 on the power unit 100 side (see, for example, the on-board mode display 13 in FIG. 3 described later). In this case, when one of the switching units selects which of the two to enable, the same selection is set in the other switching unit. However, this example does not exclude a configuration in which the switching unit is not arranged in the management device 103.

[0026] The power supply unit 203 normally receives power from a commercial power supply network and supplies the power to components requiring power in the power unit 100 and the external control device 200. Note that when a power outage occurs (i.e., when the supply of power from the commercial power supply network is stopped), the power supply unit 203 may receive power from the battery 105 (and / or the generator 102) of the power unit 100.

[0027] In addition, the external control device 200 may have a notification unit such as a speaker. The notification unit notifies the surrounding area of ​​the operating state of the power unit 100, etc.

[0028] <1-3. Display screen 10 in management device 103> Next, the display screen 10 of the display unit 1031 in the management device 103 will be described with reference to Fig. 3 to Fig. 5. Fig. 3 is a diagram showing a display example of the main management screen 1. Fig. 4 is a diagram showing a display example of the temperature management screen 2. Fig. 5 is a diagram showing a display example of the warning list screen 3.

[0029] As shown in FIGS. 3 to 5, the display unit 1031 can switch between displaying multiple display screens 10. In this embodiment, the multiple display screens 10 include a main management screen 1, a temperature management screen 2, and a warning list screen 3, all of which are shown in FIG. 3. In addition, the multiple display screens 10 include a high temperature management screen, a pressure management screen, a status management screen, a warning history list screen, and a setting change screen. Note that the multiple display screens 10 need only include at least the main management screen 1, and are not limited to the above examples. In other words, the multiple display screens 10 may include screens other than those described above, or may not include at least one of the above screens other than the main management screen 1.

[0030] <1-3-1. Main management screen 1> The main management screen 1 will be described with reference to Fig. 3. The main management screen 1 is the main screen of the display unit 1031. On the main management screen 1, a plurality of measurement value displays 11, an operating status display 12, a machine side mode display 13, a plurality of tabs 14, and a date and time display 15 are arranged.

[0031] <1-3-1-1. Measurement value display 11> On the main management screen 1, the display unit 1031 displays measurement value displays 11. The measurement value displays 11 show measurement values ​​of measurement targets of the power unit 100, and in this embodiment, display measurement values ​​of measurement targets with high importance. Each measurement value display 11 is displayed in a corresponding display area 110 and is displayed regularly on the main management screen 1. Note that while the number of measurement value displays 11 is six in FIG. 3, this is not limited to this example and the number may be one or a plurality of numbers other than six. The arrangement of each measurement value display 11 is not particularly limited. For example, the arrangement of the multiple measurement value displays 11 is a two-dimensional arrangement of 3 columns x 2 rows in FIG. 3, but the arrangement may be a two-dimensional arrangement with a different number of rows and / or columns, or may not be a two-dimensional arrangement.

[0032] The measurement value display 11 has an item display 111 , a meter display 112 , and a numeric display 113 .

[0033] The item display 111 is arranged in an item display area 1110 and displays the name of the measurement target. The item display area 1110 occupies the upper part of the display area 110 of the item display 111 in FIG.

[0034] The meter display 112 is arranged in a meter area 1120 and shows the measurement value of the measurement target displayed in the item display 111. The meter area 1120 is arranged in the display area 110 below the item display area 1110 in Fig. 3. The meter display 112 has an axis display 1121 and a needle display 1122. Note that the meter area 1120 and the axis display 1121 are arc-shaped in Fig. 3, but are not limited to this example and may be circumferentially shaped.

[0035] The axis display 1121 extends along the circumference of the meter area 1120. The needle display 1122 moves a distance corresponding to the measurement value along the axis display 1121 in a circumferential direction based on the center point of the arc-shaped or circumferentially shaped axis display 1121. In other words, the needle display 1122 moves from the reference position of the axis display 1121 (for example, the position of the origin where the measurement value = 0) to a circumferential position the distance corresponding to the measurement value.

[0036] Numerical value display 113 is arranged in numeric value area 1130, and displays the measurement value (the numerical value) and its unit of the measurement target displayed in item display 111. Numerical value area 1130 is arranged inside meter area 1120 in display area 110. Numerical value area 1130 is circular in FIG. 3, but is not limited to this example and may be fan-shaped. Alternatively, numeric value area 1130 may be elliptical or n-sided (n is an integer equal to or greater than 1).

[0037] According to the management system 300, the numerical display 113 is arranged inside the arc-shaped or circumferential meter display 112. Therefore, compared to a configuration in which the numerical display 113 is arranged outside the meter display 112, for example, the numerical display 113 is displayed larger in each measurement value display 11. This improves the visibility of the display of the measurement object (especially the measurement value).

[0038] Preferably, each measurement value display 11 is displayed in a separate area, i.e., does not overlap. This prevents at least a portion of a measurement value display 11 from being obscured by another measurement value display 11. Therefore, each measurement value display is displayed in its entirety. Therefore, even if multiple measurement value displays are displayed on the same display screen 10, each measurement value display can be reliably viewed.

[0039] Furthermore, in the measurement value display 11, at least a portion of the needle indicator 1122 is disposed between the meter area 1120 and the numeric area 1130. Specifically, the needle indicator 1122 is disposed between the meter area 1120 and the numeric area 1130, outside the numeric area 1130. The needle indicator 1122 extends radially outward from the center point of the axis indicator 1121 toward the meter area 1120. The tip end (radially outer end) of the needle indicator 1122 preferably reaches the inner circumferential edge (radially inner end) of the meter area 1120, and more preferably is positioned radially outward from the inner circumferential edge of the meter area 1120. Furthermore, the tip end of the needle indicator 1122 may be positioned radially outward from the outer end (radially outer end) of the axis indicator 1121. This allows the position pointed by the needle indicator 1122 relative to the axis indicator 1121 to be reliably seen. However, the above example does not exclude a configuration in which the tip of the needle indicator 1122 in at least one measurement value indicator 11 does not reach the inner circumferential edge (inner edge in the radial direction) of the meter area 1120.

[0040] Furthermore, in the measurement value display 11, the background color of the numerical region 1130 is preferably different from the background color of the region outside the numerical region 1130. This makes it easier to distinguish the numerical region 1130 from other regions. Therefore, the numerical display 113 displayed in the numerical region 1130 becomes easier to see. However, this example does not exclude a configuration in which the background color of at least a portion of the region outside the numerical region 1130 is the same background color as or a similar color to the numerical region 1130.

[0041] <1-3-1-2. Operation status display 12> On the main management screen 1, the display unit 1031 displays an operating state display 12 together with a measurement value display 11. The operating state display 12 indicates the operating state of the power unit 100. For example, the operating state display 12 includes "stopped", "starting failed", "starting preparation completed", "starting", "starting failed", "emergency stop", "operating", etc.

[0042] "Stopped" indicates a state in which the operation of the power unit 100 has stopped. "Start unsuccessful" indicates a state in which the engine 101 cannot be started. "Start ready" indicates that preparations for starting the engine 101 have been completed. "Starting" indicates that the engine 101 has been successfully started and the power unit 100 is in an operable state. "Start failed" indicates that the engine 101 has failed to start and the power unit 100 is in an inoperable state. "Emergency stop" indicates that the power unit 100 has been brought to an emergency stop, for example, by an emergency stop operation in the management device 103 or the external control device 200. "In operation" indicates a state in which the power unit 100 is operating normally.

[0043] Preferably, the background colors (for example, gray) of the displays of "Stopped" and "Ready to start", the background colors (for example, red) of the displays of "Start not established", "Start failed", and "Emergency stop", and the background colors (for example, green) of the displays of "Starting" and "Running" are all different. This allows the worker to intuitively identify the degree of stability of the operating state of the power unit 100 (in other words, the degree of danger) by looking at the operating state display 12.

[0044] <1-3-1-3. On-board mode display 13> On the main management screen 1, the display unit 1031 further displays an on-machine mode display 13 along with the measurement value display 11. The on-machine mode display 13 indicates whether an operation input from the management device 103 or an operation input from the external control device 200 is valid. In other words, the on-machine mode display 13 indicates whether the power unit 100 can be controlled by the external control device 200 arranged outside the power unit 100. In other words, the on-machine mode display 13 indicates whether the power unit 100 can be controlled based on an operation input from the management device 103 on the power unit 100 side. In this embodiment, the on-machine mode display 13 displays either "ON" or "OFF".

[0045] "ON" indicates that the operation input from the management device 103 is valid and the operation input from the external control device 200 is invalid. In other words, this indicates that the power unit 100 can be controlled by the operation input from the management device 103.

[0046] "OFF" indicates that the operation input from the management device 103 is invalid and that the operation input from the external control device 200 is valid. In other words, this indicates that the power unit 100 can be controlled by the operation input from the external control device 200.

[0047] The on-machine mode display 13 allows the worker to identify whether the control of the management device 103 or the external control device 200 is enabled.

[0048] The on-device mode display 13 may be switchable between "ON" and "OFF" by both the management device 103 and the external control device 200, or by only one of them. For example, the on-device mode display 13 may be switched between "ON" and "OFF" by an operation input on the input unit 1032 of the management device 103, or by touching the on-device mode display 13.

[0049] <1-3-1-4. Tab 14> The display unit 1031 further displays a plurality of tabs 14 on the display screen 10. The plurality of tabs 14 are arranged on each display screen 10, and in this embodiment, are arranged side by side in the left-right direction of the drawing at the top of the display screen 10 as shown in Figures 3 to 5. However, the arrangement of the plurality of tabs 14 is not limited to the examples shown in Figures 3 to 5.

[0050] Each tab 14 is a switching display that can be touched to switch the display screen 10, and each tab 14 is individually associated with a different display screen 10. That is, when any tab 14 is selected by a touch operation, the display control unit 1042 switches the display to the display screen 10 corresponding to that tab 14 on the display unit 1031. The background color of the tab corresponding to each screen that has been switched and displayed is a different background color from the other tabs 14.

[0051] For example, in this embodiment, the multiple tabs 14 include a TOP tab 141, a temperature tab 142, a temperature (high temperature) tab, a pressure tab, a status tab, an alarm list tab 143, an alarm history tab, and a settings tab.

[0052] The TOP tab 141 is associated with the main management screen 1. When the TOP tab 141 is touched, the display screen 10 is switched to the main management screen 1, and the background color of the TOP tab 141 changes.

[0053] Furthermore, the temperature tab 142 is associated with the temperature control screen 2. When the temperature tab 142 is touched, the display screen 10 is switched to the temperature control screen 2, and the background color of the temperature tab 142 changes (see FIG. 4).

[0054] Moreover, the alarm list tab 143 is associated with the warning list screen 3. When the alarm list tab 143 is touched, the display screen 10 is switched to the warning list screen 3, and the background color of the alarm list tab 143 changes (see FIG. 5).

[0055] In addition, the Temperature (High Temperature) tab is associated with the High Temperature Management screen. The Pressure tab is associated with the Pressure Management screen. The Status tab is associated with the Status Management screen. The Alarm History tab is associated with the Warning History List screen. The Settings tab is associated with the Settings Change screen.

[0056] <1-3-1-5.Date and time display 15> The display unit 1031 further displays a date and time display 15 on the display screen 10. The date and time display 15 displays the current date and time. The date and time display 15 is displayed on all display screens 10, and in this embodiment, is arranged with multiple tabs 14 in the upper right portion of the display screen 10 as shown in FIGS. 3 to 5. However, the arrangement of the date and time display 15 is not limited to the examples shown in FIGS. 3 to 5.

[0057] <1-3-2. Temperature management screen 2> Next, the temperature management screen 2 will be described with reference to Fig. 4. The temperature management screen 2 has a plurality of tabs 14, a date and time display 15, and a plurality of measurement value displays 21. That is, on the temperature management screen 2, the display unit 1031 displays the measurement value displays 21.

[0058] In this embodiment, each measurement value display 21 indicates the current temperature of each measurement target in the diesel engine of the engine 101. The measurement targets in Fig. 4 are "lubricating oil temperature," "high-temperature coolant temperature," "low-temperature coolant temperature," "fuel (temperature in the flow path)," and "intake air temperature."

[0059] The multiple measurement value displays 21 are arranged side by side in the left-right direction of the drawing on the temperature management screen 2. The arrangement of the multiple measurement value displays 21 is not limited to the example shown in Fig. 4. Also, although the number of measurement value displays 21 is five in Fig. 4, it is not limited to this example and may be one or a multiple number other than five.

[0060] Each measurement value display 21 has an item display 211 , a detail display 212 , a numerical value display 213 , a bar display 214 , and a threshold display 215 .

[0061] The item display 211 shows the name of the measurement object. The detailed display 212 shows simple information for identifying the measurement object. The numerical display 213 shows the temperature of the measurement object shown in the item display 211 as a numerical value. The bar display 214 shows the temperature of the measurement object shown in the item display 211 as a bar graph. One or two threshold displays 215 are arranged on the scale of the bar display 214. The threshold displays 215 show the threshold value of the temperature of the measurement object shown in the item display 211. Of the two threshold displays 215, the threshold display 215 on the upper side of the drawing shows the upper limit value, and the threshold display 215 on the lower side of the drawing shows the lower limit value.

[0062] <1-3-3. Warning list screen 3> Next, the warning list screen 3 will be described with reference to Fig. 5. The warning list screen 3 displays a list of measurement targets in which abnormal measurement values ​​have been detected. In addition to multiple tabs 14 and a date and time display 15, the warning list screen 3 also displays a list display 31, a history display 32, and operation displays 33 and 34. That is, on the warning list screen 3, the display unit 1031 displays these.

[0063] The list display 31 displays, in chronological order, at least some of the items related to the measurement object for which abnormal measurement values ​​have been detected at the present time. The list display 31 has a date display 311 and a warning content display 312. The date display 311 indicates the date and time when the abnormal measurement value that is currently being detected occurred. The warning content display 312 is located to the right of the date display 311 in FIG. 5, and indicates details of the measurement object for which the date and time of occurrence indicated by the date display 311.

[0064] The history display 32 displays a chronological list of at least some of the events related to measurement objects in which abnormal measurement values ​​have been detected up to the present time. The history display 32 also includes events related to measurement objects in which abnormal measurement values ​​have been resolved to date. The history display 32 has a date display 321 and a warning content display 322. The date display 321 indicates the date and time when the first abnormal measurement value detected up to the present time was measured. The warning content display 312 is located to the right of the date display 321 in FIG. 5 and indicates details of the measurement object whose occurrence date and time are indicated by the date display 321.

[0065] The operation display 33 is a touch-operable icon for changing the items displayed in the list display 31. The operation display 33 has a position display 331, an up-down display 332, and a down-down display 333. The position display 331 indicates the chronological position of the item displayed in the list display 31 with respect to the items that can be displayed in the list display 31. The position display 331 can be slid up or down in the drawing of FIG. 5 by a touch operation. This makes it possible to change the items displayed in the list display 31. The up-down display 332 is a touch-operable icon for displaying an item with a more recent occurrence date and time in the list display 31. The down-down display 333 is a touch-operable icon for displaying an item with an older occurrence date and time in the list display 31.

[0066] The operation display 34 is a touch-operable icon for changing the items displayed on the history display 32. The operation display 34 has a position display 341, an up-down display 342, and a down-down display 343. The position display 341 indicates the chronological position of the item displayed on the history display 32 with respect to the items that can be displayed on the history display 32. The position display 341 can be slid up and down in the drawing of FIG. 5 by a touch operation. This makes it possible to change the items displayed on the history display 32. The up-down display 342 is a touch-operable icon for displaying an item with a more recent occurrence date and time on the history display 32. The down-down display 343 is a touch-operable icon for displaying an item with an older occurrence date and time on the history display 32.

[0067] Preferably, when a new abnormal measurement value is detected in any of the measurement objects, the display control unit 1042 displays a warning list screen 3 on the display unit 1031. This allows the worker to immediately recognize the occurrence of an abnormality in the measurement object and quickly resolve the abnormality in the measurement object.
