Description

[Technical Field]

[0001] The present invention relates to an information display and an information display method for a fluid transfer device equipped with a rotary machine such as a water supply device, a land pump, a submersible pump, a compressor, and a blower, and in particular to an information display and an information display method for displaying an alarm for a fluid transfer device. [Background technology]

[0002] Fluid transfer devices that transfer fluids, such as liquids or gases, using rotary machines such as water supply systems, land pumps, submersible pumps, compressors, or fans are used in a variety of fields. For example, a water supply system includes a pump, which is a rotary machine for pressurizing water, an electric motor for driving the pump, and a control device for controlling the operation of the electric motor, and is used as a device for supplying water to buildings such as office buildings and apartment buildings (see, for example, Patent Document 1). The water supply system is connected directly to a water main or via a water tank, and transfers water flowing through the water main at a predetermined pressure to water supply fixtures (e.g., faucets) within the building.

[0003] In recent years, inverter-integrated motors have come into use with the aim of reducing the size of fluid transfer devices and increasing the efficiency and energy savings of electric motors (see, for example, Patent Document 2). These inverter-integrated motors not only enable the motor to be operated with high efficiency, but also achieve significant energy savings by combining variable speed operation with inverter control. Furthermore, the integration of the motor and inverter allows for the size reduction of fluid transfer devices. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-165433 [Patent Document 2] Patent Publication No. 2021-87300 Summary of the Invention [Problem to be solved by the invention]

[0005] When an abnormality occurs in a fluid transfer device and an alarm is issued from the fluid transfer device, if the cause of the abnormality is minor, it may be possible for someone other than a specialized worker (e.g., a serviceman from the manufacturer of the fluid transfer device) (e.g., the owner and user of the fluid transfer device) to resolve the cause of the abnormality and ultimately cancel the alarm.

[0006] However, it is often difficult for people other than specialized workers to determine whether the cause of an abnormality that has occurred in a fluid transfer device is minor, and even more so, where the cause of the abnormality lies.

[0007] If people other than specialized workers can quickly eliminate the cause of an abnormality, there is a higher chance that serious failures such as the shutdown of rotating machinery can be prevented or resolved quickly. In particular, in the case of fluid transfer equipment used as infrastructure equipment such as water supply systems, the shutdown of rotating machinery (for example, the shutdown of a water supply system pump) can pose a major problem, as it prevents the supply of substances (for example, water) essential for maintaining human life to consumers.

[0008] Therefore, an object of the present invention is to provide an information display device that can at least assist even non-specialized workers in resolving the cause of an abnormality, and to provide a method for displaying information on an information display device that can at least assist in resolving the cause of an abnormality. [Means for solving the problem]

[0009] In one aspect, an information display is provided that includes a communication unit configured to receive information from a fluid transfer device equipped with a rotating machine, a calculation unit that processes the information received by the communication unit, and a display that displays the information processed by the calculation unit, wherein the communication unit receives the contents of an alarm that has occurred in the fluid transfer device, and the calculation unit displays alarm information on the display that includes the contents of the alarm and a checklist that lists the check items that must be checked to cancel the alarm.

[0010] In one aspect, the computing unit displays an alarm reset button on the display for transmitting an alarm reset signal to the fluid transfer device. In one aspect, the calculation unit displays a data transmission button on the display for transmitting the check results of the checklist to at least one of a management center, a cloud server, and an external server. In one embodiment, when the data transmission button is tapped, the calculation unit transmits specific information about the fluid transfer device to at least one of the management center, a cloud server, and an external server, and the specific information includes at least one of equipment information about the fluid transfer device, contact information for a user of the fluid transfer device, and operating status information of the fluid transfer device.

[0011] In one embodiment, when an alarm with the same content as the alarm is issued again after the alarm reset button is tapped, the calculation unit displays a contact button on the display for sending information including the content of the alarm and the fact that the abnormality could not be resolved by simply checking the check items on the checklist to at least one of a management center, a cloud server, and an external server. In one aspect, the calculation unit displays the checklist on the display only when the alarm is an alarm that allows a user to check the cause of an abnormality occurring in the fluid transfer device.

[0012] In one aspect, an information display method is provided that receives the content of an alarm that has occurred in a fluid transfer device equipped with a rotating machine, and displays alarm information on a display that includes the content of the alarm and a checklist that lists the check items that must be confirmed to cancel the alarm.

[0013] In one embodiment, an alarm reset button is displayed on the display for sending an alarm reset signal to the fluid transfer device. In one aspect, a data transmission button for transmitting the check results of the checklist to at least one of a management center, a cloud server, and an external server is displayed on the display. In one aspect, when the data transmission button is tapped, specific information about the fluid transfer device is sent to at least one of the management center, a cloud server, and an external server, and the specific information includes at least one of equipment location information about the fluid transfer device, contact information for the user of the fluid transfer device, and operating status information about the fluid transfer device.

[0014] In one embodiment, if an alarm with the same content as the alarm is issued again after tapping the alarm reset button, a contact button is displayed on the display for sending information including the content of the alarm and the fact that the abnormality could not be resolved by simply checking the check items on the checklist to at least one of the management center, cloud server, and external server. In one aspect, the checklist is displayed on the display only when the alarm is an alarm that allows a user to check the cause of an abnormality occurring in the fluid transfer device. [Effects of the Invention]

[0015] According to the present invention, by displaying a checklist for canceling an alarm on the display, even a user who is not a specialized worker can increase the likelihood of being able to resolve the cause of an abnormality that has occurred in the fluid transfer device and cancel the alarm. In other words, the checklist displayed on the display can be used to assist the user in resolving the cause of the abnormality. [Brief explanation of the drawings]

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In Figures 1 to 6, the same or corresponding components are designated by the same reference numerals, and redundant description will be omitted. Fig. 1 is a schematic diagram showing a fluid transfer device according to one embodiment. The fluid transfer device shown in Fig. 1 is a direct-coupled water supply device used in buildings such as office buildings and apartment buildings. In the following, the water supply device will be described as an example of a fluid transfer device.

[0018] As shown in Figure 1, the suction port of the water supply device is connected to a water main 4 via an inlet pipe 5. A water distribution pipe 7 is connected to the discharge port of the water supply device, and this distribution pipe 7 communicates with water supply fixtures (e.g., faucets) located inside the building. The water supply device boosts the water from the water main 4 to a predetermined pressure and supplies the water to each water supply fixture in the building.

[0019] As shown in FIG. 1 , the water supply apparatus includes a pump 2 connected to a water main 4 via an inlet pipe 5, an electric motor 3 as a drive source for driving the pump 2, a temperature sensor 18 for measuring the temperature of the pump 2, an inverter 21 for varying the speed of the electric motor 3, a control device 20 for controlling the water supply operation of the water supply apparatus (i.e., the operation of the pump 2), a check valve 22 disposed downstream of the pump 2, a flow rate detector (flow switch) 24, a discharge-side pressure sensor 26, and a pressure tank 28 disposed downstream of the check valve 22, and a display 49 for displaying operating status information. In this embodiment, these components are housed within a cabinet 30. In another embodiment, only some of the above components (for example, only the control device 20 and the inverter 21) may be housed within the cabinet 30.

[0020] The check valve 22 is provided in the discharge pipe 8 connected to the discharge port of the pump 2, and is a valve for preventing backflow of water when the pump 2 is stopped. The flow rate detector 24 is a device for detecting whether the flow rate of water flowing through the discharge pipe 8 is below a predetermined low water rate (i.e., a low water rate state). The flow rate detector 24 is, for example, a flap-type flow rate detector that detects a low water rate state when a flap comes into contact with a contact. Alternatively, the flow rate detector 24 may be, for example, a float-type flow rate detector that detects a low water rate state when a float comes into contact with a contact. The discharge-side pressure sensor 26 is a water pressure measuring device for measuring the discharge-side pressure of the pump 2. The pressure tank 28 is a pressure retainer for maintaining the discharge-side pressure while the pump 2 is stopped. The water distribution pipe 7 is connected to the discharge pipe 8.

[0021] One end of a suction pipe 9 is connected to the suction port of the pump 2, and the other end of the suction pipe 9 is connected to the introduction pipe 5. A backflow preventer and a suction-side pressure sensor (not shown) are attached to the suction pipe 9. The backflow preventer is installed to reliably prevent water from flowing back into the water main 4.

[0022] The water supply device is equipped with a bypass pipe 11 that bypasses the pump 2. The upstream end of the bypass pipe 11 is connected to the suction pipe 9, and the downstream end of the bypass pipe 11 is connected to the discharge pipe 8. A check valve 16 is attached to the bypass pipe 11 to prevent backflow of water within the bypass pipe 11. This bypass pipe 11 is provided so that water can be supplied using only the inflow pressure, even when the pump 2 is stopped.

[0023] The inverter 21, flow rate detector 24, discharge side pressure sensor 26, and temperature sensor 18 are connected to the control device 20 via signal lines. When the flow rate detector 24 detects a low water flow state, the control device 20 issues a command to the inverter 21 to temporarily increase the operating speed of the pump 2, accumulates pressure in the pressure tank 28, and then stops the operation of the pump 2 (low water flow stop). On the other hand, when the discharge side pressure (water pressure in the discharge pipe 8) drops to a predetermined value (start pressure), the control device 20 issues a command to the inverter 21 to start the operation of the pump 2.

[0024] The control device 20 controls the operation of the inverter 21 and the electric motor 3, thereby controlling the operation of the pump 2. More specifically, the control device 20 controls the operating speed (i.e., rotation speed) of the pump 2 based on the output signal of the discharge-side pressure sensor 26. In general, constant discharge pressure control is performed, in which the operating speed of the pump 2 is controlled so that the pressure signal measured by the discharge-side pressure sensor 26 coincides with a set target pressure, thereby controlling the discharge pressure of the pump 2 to be constant, or constant estimated terminal pressure control is performed, in which the target value of the discharge pressure of the pump 2 is appropriately changed to control the water pressure at the water supply tap to be constant.

[0025] Next, an example of the control device 20 will be described in more detail with reference to FIG. 1. The control device 20 shown in FIG. 1 includes a setting unit 46, a memory unit 47, a calculation unit 48, an I / O unit 50, and an operation panel 51. The operation panel 51 functions as a human interface. Various setting values ​​related to the operation control of the pump 2 are input to the setting unit 46. The display 49 described above is provided on the operation panel 51 together with the setting unit 46. In this embodiment, the display 49 is a liquid crystal panel, and the setting unit 46 is a touch panel type operating device. Although the display 49 shown in FIG. 1 is attached to the control device 20, the display 49 may be located away from the control device 20. The display 49 may also be configured by combining a liquid crystal panel with a 7-segment LED or an indicator light.

[0026] The memory unit 47 stores operational status information of the water supply apparatus. The operational status information of the water supply apparatus includes, for example, the operating status of the pump 2 (e.g., the ON / OFF state of the pump 2, the command value to the inverter 21, and the rotation speed of the electric motor 3), the accumulated operating time of the pump 2 and the electric motor 3, the history of the command values ​​to the inverter 21, the output values ​​and alarm setting values ​​of various devices such as the temperature sensor 18, the flow rate detector 24, and the discharge pressure sensor 26, as well as the presence or absence of malfunctions and their malfunction history for these devices 18, 21, 24, and 26. A CPU is used as the calculation unit 48. The display 49 functions as a human interface and is configured to display operational information. The user can clear the display on the display 49 by pressing the clear button 53 on the setting unit 46.

[0027] The control device 20 shown in FIG. 1 further includes a communication unit 60. The communication unit 60 of the control device 20 is configured to be connectable to an information display device 61 (described later) via wired or wireless communication. Examples of the information display device 61 include general-purpose mobile terminals such as smartphones, mobile phones, and tablet devices. In this embodiment, the information display device 61 is a smartphone, which is an example of a high-performance display device that includes a display 64 that is a liquid crystal screen and that can be used for touch input or push button input to the display 64.

[0028] The information display 61 shown in Fig. 1 includes a communication unit 62 connected to the communication unit 60 of the control device 20 via wired or wireless communication, the above-mentioned display 64, a calculation unit 65 which is a CPU, and a memory unit 66. In this embodiment, the communication unit 62 of the information display unit 61 is configured to be connectable to the communication unit 60 of the control device 20 using wireless communication means such as NFC or Bluetooth (registered trademark) so as to be able to send and receive various information. The control device 20 of the water supply apparatus transmits the above-mentioned operating status information to the communication unit 62 of the information display unit 61 via the communication unit 60. Furthermore, the communication unit 62 of the information display 61 is configured to be able to communicate with an external storage device such as a cloud server 70 and / or an external server 71 via a network such as the Internet.

[0029] The calculation unit 65 of the information display unit 61 is configured to be able to process the operating status information of the water supply apparatus received by the communication unit 62. For example, the calculation unit 65 stores all or part of the operating status information received by the communication unit 62 in the memory unit 66, or displays the operating status information on the display 64 based on operations by the user of the information display device 61. An application that enables such operations is downloaded to the information display device 61 as appropriate from, for example, the cloud server 70 or external server 71 via a network such as the Internet, and stored in the memory unit 66.

[0030] In the water supply device shown in Figure 1, the inverter 21 is installed separately from the electric motor 3, but the water supply device may also have an inverter-integrated electric motor in which the inverter 21 is integrated with the electric motor 3. Figure 2 is a schematic diagram showing an example of an inverter-integrated electric motor. The configuration of this embodiment that is not particularly described is the same as the above-mentioned embodiment, so duplicated description will be omitted.

[0031] As shown in FIG. 2, inverter-integrated electric motor 80 is configured by integrating electric motor 3 and inverter 21. Electric motor 3 is driven by inverter 21 to drive pump 2. Electric motor 3 is, for example, a permanent magnet synchronous motor. In one embodiment, electric motor 3 may be various types of motors, such as an induction motor or a DC brushless motor. The drive shaft of electric motor 3 is connected to pump 2 directly or indirectly via a coupling or the like, and is housed in cabinet 30 of the water supply apparatus (see FIG. 1). In one embodiment, inverter-integrated electric motor 80 may be located outside cabinet 30 of the water supply apparatus. Furthermore, inverter-integrated electric motor 80 may be used as a standalone pump device (fluid transfer device) for pumping fluid flowing through piping located outdoors or indoors.

[0032] Like the inverter 21 shown in FIG. 1, the inverter 21 of the inverter-integrated electric motor 80 shown in FIG. 2 also functions as a speed adjusting device for the pump 2, and the inverter-integrated electric motor 80 incorporates a control device (e.g., a control board) 81 having a configuration similar to that of the control device 20 described above. More specifically, the control device 81 has a calculation unit 48 that calculates a command value to be issued from the inverter 21 to the electric motor 3 based on the output signal of the discharge-side pressure sensor 26, and a memory unit 47 that stores operating state information of the water supply apparatus. Furthermore, the inverter-integrated motor 80 has a communication unit 60 configured to be connectable to the communication unit 62 of the information display 61 described above via wired or wireless communication. The information display 61 shown in FIG. 2 is also a smartphone (mobile terminal) having a configuration similar to that of the information display 61 shown in FIG. 1.

[0033] When an abnormality occurs in the water supply apparatus, the control device 20 issues an alarm and notifies the user and / or owner of the water supply apparatus (hereinafter simply referred to as the "user") of the occurrence of the abnormality. The user who receives the alarm can use the information display 61 to receive the contents of the alarm from the water supply apparatus.

[0034] When the information display 61 receives the details of an alarm from the water supply apparatus, the calculation unit 65 of the information display 61 displays the received alarm details, a checklist for clearing the cause of the abnormality corresponding to the alarm, and an alarm reset button on the display 64 of the information display 61. Such checklists are created in advance corresponding to all alarms that occur in the water supply apparatus and are stored in advance in the memory unit 66 of the information display 61 as a database, for example. In one embodiment, the calculation unit 65 of the information display 61 may read the checklist corresponding to the received alarm from an external storage device such as the cloud server 70 or external server 71 via the communication unit 62. In this specification, information including at least the details of the alarm and the checklist for clearing the alarm is referred to as "alarm information." Note that if the model of the water supply apparatus changes, the alarm information including the checklist displayed on the display 64 may differ even for the same alarm. Therefore, the alarm information is created according to the model of the water supply apparatus. Furthermore, in this embodiment, the water supply apparatus is described as an example of a fluid transfer apparatus, but the alarm information also differs when the type of fluid transfer apparatus is different. Therefore, the alarm information is created in response to an alarm that occurs in the fluid transfer device that is the subject of this embodiment.

[0035] Fig. 3 is a schematic diagram showing an example of alarm information displayed on the display 64 of the information display device 61. The alarm information shown in Fig. 3 corresponds to the "pump overheat" alarm that is generated when the measurement value of the temperature sensor 18 (see Fig. 1) exceeds the alarm setting value. As shown in Fig. 3, the display 64 displays the content of the alarm, "pump overheat," and further displays at least one check item (three in the illustrated example) that the user must check in order to resolve the cause of the "pump overheat" abnormality and cancel the alarm.

[0036] In the example shown in Figure 3, the causes of the pump overheating abnormality are assumed to be "1. Abnormality in the pressure tank 28," "2. Improper insertion of the connector of the temperature sensor 18," and "3. Abnormal temperature of the water flowing into the water supply device." By following the items on the checklist, the user can easily check the status of the water supply device and / or the status of various devices indicated in the check items.

[0037] It is assumed that it may be difficult for a user to check the status of the water supply device and / or the status of the equipment listed in the check items. In such cases, image data that can identify the equipment to be checked may be displayed on the display 64 by tapping the check item. Figure 4 is a schematic diagram showing an example of image data that is displayed on the display 64 of the information display device 61 when the check item "Check the insertion status of the temperature sensor connector" shown in Figure 3 is tapped.

[0038] 4 shows an example of image data that includes an image of a control board arranged inside the control device 20 and a symbol (circle in FIG. 4) surrounding the connector of the temperature sensor 18 arranged on the control board. By displaying such image data on the display 64, the user can easily identify the connector of the temperature sensor 18 that should be checked. In one embodiment, instead of or in addition to the image data that can identify the equipment to be checked, video data for identifying the equipment to be checked may be displayed on the display 64.

[0039] FIG. 5 is a schematic diagram showing an example of the display after the check items shown in FIG. 3 have been checked. Each time the user checks a check item, they tap the box at the beginning of the check item. When all the boxes of the check items have been tapped, the alarm reset button shown at the bottom of the display 64 can be tapped. In one embodiment, the alarm reset button may be tapped regardless of the number of check items tapped (for example, even if no check items have been tapped). Furthermore, if there is even one check item whose check box cannot be tapped, the calculation unit 65 of the information display device 61 may control the display 64 so that the user cannot tap the alarm reset button. Alternatively, the calculation unit 65 of the information display device 61 may display the alarm reset button on the display 64 when all the boxes of the check items have been tapped.

[0040] When the alarm reset button is tapped, the calculation unit 65 of the information display device 61 transmits an alarm reset signal to the communication unit 60 of the water supply device via the communication unit 62. When the communication unit 60 of the water supply device receives the alarm reset signal, the control device 20 of the water supply device resets the alarm. In one embodiment, if the user taps the alarm reset button even though there is at least one check item whose checkbox cannot be tapped, the calculation unit 65 of the information display device 61 may cancel the transmission of the alarm reset signal to the water supply device 20.

[0041] In this way, by displaying a checklist for canceling an alarm on display 64, even a user who is not a specialized worker is more likely to be able to resolve the cause of an abnormality that has occurred in the water supply apparatus and cancel the alarm. In other words, the checklist displayed on display 64 assists the user in resolving the cause of the abnormality. If the user can resolve the cause of the abnormality and cancel the alarm, the possibility of preventing or quickly resolving a serious malfunction increases.

[0042] The checklist may be configured, for example, with only check items that can be checked by a user who is not a specialized worker. In this case, check items that are difficult or impossible for a non-specialized worker to check are excluded from the checklist. By displaying such a checklist on the display 64, it is possible to prevent new abnormalities due to incorrect operation by the user and to prevent existing abnormalities from expanding.

[0043] There are cases where some check items cannot be tapped because there are check items that the user cannot check. Furthermore, when the user checks a check item, the user may not be able to tap the check item because the target equipment is broken. For example, when a worker checks the pressure tank 28 (see Figure 1) according to the check item "Is the pressure tank operating normally?" shown in Figure 3, the pressure tank 28 may be damaged. In this case, the user will not be able to tap the check box for the check item "Is the pressure tank operating normally?"

[0044] Furthermore, if an abnormality occurs in a device other than the device listed in the checklist check items, the same alarm as the previous alarm may be issued after (for example, immediately after) tapping all check items and tapping the alarm reset button. In preparation for such a malfunction, the calculation unit 65 of the information display 61 may display a data transmission button (see FIG. 3) on the display 64. The data transmission button is a button that the user taps when the cause of the abnormality cannot be resolved.

[0045] In this embodiment, when the data transmission button is tapped, the calculation unit 65 of the information display 61 transmits the checklist check results to an appropriate location, such as a location where a specialized worker is employed (e.g., a service center for a water supply device). In this specification, appropriate locations to which the checklist check results should be transmitted are collectively referred to as a "management location." The storage unit 66 of the information display 61 pre-stores data (e.g., an email address) for transmitting the checklist check results. In one embodiment, the calculation unit 65 of the information display 61 may transmit the checklist check results to at least one of the management location, the cloud server 70, and the external server 71, or may transmit the checklist check results to the management location via the cloud server 70 and / or the external server 71.

[0046] By transmitting the check results, specialized workers can be notified quickly that an abnormality has occurred in the water supply device that would be difficult for the user to resolve on their own. Furthermore, the transmitted check results help specialized workers determine or estimate where the abnormality is occurring in the water supply device. For example, specialized workers can quickly determine from the transmitted check results whether there are any parts that need to be replaced. As a result, specialized workers can resolve the cause of the abnormality in the water supply device as quickly as possible.

[0047] In addition to the check results, the information transmitted by tapping the data transmission button may also include specific information about the water supply device for which an alarm has been issued. The specific information includes at least one of the equipment information about the water supply device, the user's contact information, and the operating status information of the water supply device.

[0048] The equipment information of the water supply apparatus includes at least one of the model of the water supply apparatus, the installation location (e.g., address) of the water supply apparatus, and the serial number of the water supply apparatus. The equipment information is useful for quickly dispatching a specialized worker to the installation location of the water supply apparatus, and is also useful for checking the water supply apparatus's past failure history and repair history. The user's contact information allows the specialized worker to contact the user quickly. Therefore, the specialized worker can immediately confirm the current status of the water supply apparatus from the user. The operating status information of the water supply apparatus is useful for the specialized worker to determine or estimate where an abnormality in the water supply apparatus is occurring and / or what the cause of the abnormality is. Therefore, the operating status information of the water supply apparatus allows the specialized worker dispatched to the installation location of the water supply apparatus to make appropriate preparations to resolve the cause of the abnormality in the water supply apparatus.

[0049] In one embodiment, if an alarm with the same content as the previous alarm is issued again after (for example, immediately after) tapping all check items and tapping the alarm reset button, the calculation unit 65 of the information display device 61 may display a contact button on the display 64. Fig. 6 is a schematic diagram showing an example of a display on which the contact button is displayed.

[0050] When a worker taps the contact button, the details of the alarm that has occurred in the water supply device are sent to the management center, along with information that the abnormality could not be resolved by simply checking the items on the checklist. This information allows a specialized worker to be quickly dispatched to the water supply device installation location, and the specialized worker can make appropriate preparations to resolve the cause of the water supply device abnormality.

[0051] As shown in Figure 6, in addition to the contact button, it is preferable that a notice be displayed on the display 64 informing the worker that inspection and repair work by a specialized worker is required to resolve the cause of the abnormality. Furthermore, as in the case of tapping the data transmission button described above, the information transmitted by tapping the contact button may include the above-mentioned specific information about the water supply device.

[0052] In one embodiment, the calculation unit 65 of the information display 61 may display the above-mentioned checklist and alarm reset button (see Figure 3) on the display 64 only when an alarm is issued that allows the user to check the cause of the abnormality occurring in the water supply apparatus. Furthermore, the calculation unit 65 of the information display 61 may display the contact button shown in Figure 6 when an alarm is issued that requires inspection and repair work by a specialized worker. The memory unit 66 of the information display 61 pre-stores alarms that can be checked by the user and alarms that require inspection and repair work by a specialized worker.

[0053] An example of an alarm that can be confirmed by the user is an alarm of a minor fault that does not result in an emergency shutdown of the pump 2 (see Figure 1) of the water supply device. An example of such a minor fault alarm is a fault in the flow detector 24. An example of an alarm that requires inspection and repair work by a specialized worker is an alarm other than an alarm that can be confirmed by the user, such as an alarm of a major fault that results in an emergency shutdown of the pump 2 (see Figure 1) of the water supply device. Examples of such a major fault alarm are an inverter trip and an earth leakage trip.

[0054] In this way, by changing the button displayed on the display 64 of the information display device 61 depending on the type of alarm, the user can eliminate the cause of the abnormality for minor alarms, and specialized workers can be dispatched only for serious alarms.

[0055] In the above-described embodiment, examples have been described in which various buttons displayed on the display 64 of the information display device 61 are tapped, but the present embodiment is not limited to these examples. For example, if the information display device 61 has a voice recognition function, the same effects as when the alarm reset button, data transmission button, and contact button are tapped may be generated by a voice uttered by the user.
