Description

The present invention relates to a pump device and a management device.

BACKGROUND ART Pump devices that have a plurality of pumps and can be operated individually are widely known. This type of pump device has an operation LED (Light-Emitting Diode) that indicates the operating status of each pump, a failure LED that indicates a failure for each pump, and a 7-segment LED and display that indicates the operating status of the entire pump device or the type of failure. It is equipped with a panel.

Thereby, when any of the pumps fails, the pump device lights up the failure LED corresponding to the failed pump, and the failure type of the failed pump can be displayed on the 7-segment LED and the display panel.

Meanwhile, the pumps other than the one that failed continue to operate. Therefore, when the operator confirms the operation information of other pumps, he operates the operation buttons of the pump device, clears the failure indications on the 7-segment LED and the display panel, and displays the operation information on the display panel. At this time, on the display panel, the operating information of the failed pump is displayed as zero (the current, voltage, and frequency are displayed as zero values), and the operating information of the other pumps is displayed. After that, if the operator wants to reconfirm the type of failure of the failed pump, the operator operates an operation button or the like on the pump device to display the type of failure on the display panel again.

There is no particular problem with such a pump device, but according to the study of the present inventor, when checking the state indicated by the operation information of each pump and the state indicated by the failure type of each pump, it is difficult to perform the operation for each state. There is room for improvement in that it requires time and effort to operate.

Patent No. 6845648

An object of the present invention is to reduce the effort required for checking the status of each pump.

According to one aspect of the present invention, the pump device includes a plurality of pumps and operates each of the pumps.

The display section displays a list of the operation information and the status information for each pump.

According to another aspect of the invention, the management device is a device capable of communicating with the pump device. The management device includes a receiving section, a log storage section, a log determining section, and an output section. The receiving unit receives, for each pump, one of the transmitted operation information, state information, and operation prohibition information from the pump device. The log storage unit stores, for each pump, one of the received operation information, state information, and operation prohibition information, and a reception time as log data. The log determination unit determines whether the display of the driving prohibition information continues for a certain period or more based on the log data. When the display continues, the output unit outputs error information indicating the pump device in which the display of the operation prohibition information continues.

According to the present invention, it is possible to reduce the effort required for checking the status of each pump.

For example, when pump No. 1 of the plurality of pump units 60 is in an overcurrent state, the 7-segment LED 561 displays the code "1-oC". For example, when the pump device 5 is in a normal state, the 7-segment LED 561 displays the code "H 37".

The display panel 562 is under display control by the processor 58 and displays various information on the screen. For example, a liquid crystal display is mounted as the display panel 562, but the display panel 562 is not limited thereto. Display panel 562 is an example of a display section.

The storage device 57 is a memory device such as a ROM, RAM, HDD, SSD (solid state drive), or integrated circuit storage device that stores various data. The storage device 57 may be realized by one physical memory device, or may be realized by a plurality of physically separated memory devices within the pump device 5. Hereinafter, the storage device 57 will be simply referred to as a memory.

The processor 58 is an arithmetic device such as a CPU or a microprocessor. The processor 58 may be configured by a dedicated circuit such as an ASIC or an FPGA. The processor 58 executes various programs stored in the storage device 57 to realize the functions of the pump device, for example, the functions of the control section 581, the operation processing section 582, and the communication section 583. Note that some functions are optional additional items and may be omitted. For example, the communication unit 583 may be omitted. Further, the functions of each of the control section 581, operation processing section 582, and communication section 583 can be changed or omitted as appropriate. For example, the control unit 581 may include the functions of the operation processing unit 582. Similarly, the control section 581 may include the functions of the communication section 583. Furthermore, the functions of the control section 581, the operation processing section 582, and the communication section 583 may be collectively described as each function of the processor 58, without being separately explained as follows.

The control unit 581 operates each pump among the plurality of pump units 60 for which operation is permitted. Further, the control unit 581 determines whether the operation of each pump is normal based on, for example, a sensor signal from a sensor (not shown). Furthermore, based on the determined result, the control unit 581 causes the display panel 562 to display operating information for each pump if the condition is normal, and causes the display panel 562 to display status information regarding the abnormal condition if the pump is not in a normal condition. . The operating information is information regarding the operation of the inverter for each pump, and includes, for example, operating frequency, voltage, and current values. The driving information may also be called monitor information. The status information is information regarding the abnormal status of each pump, and may be, for example, text information representing the type of abnormal status for the failure LED lamp 566b that lights up in the case of an abnormal status. At this time, the control unit 581 causes the display panel 562 to display a list of operation information and status information for each pump. Similarly, the control unit 581 displays a code indicating the state of the pump device 5 on the 7-segment LED 561 based on the determined result. Further, the control unit 581 may control the smooth operation of each pump so as to periodically smooth the cumulative operation time of each pump. The control unit 581 is an example of a determination unit, a display control unit, and a smooth operation control unit.

The operation processing unit 582 sets various information and controls the display device 56 installed on the operation panel 560 in accordance with the operation of the input device 53 installed on the operation panel 560. For example, the operation processing unit 582 resets the alarm of the pump device 5 and the like, as well as the abnormality display on the 7-segment LED 561 and the display panel 562, in response to the operator's operation of the reset button 533.

Further, the operation processing unit 582 makes settings for permitting or prohibiting operation of each pump in accordance with the operation of the selection/stop button 535 by the operator. Specifically, the control unit 581 and the inverter 54 are connected by serial communication, and the maximum number of inverters that the control unit 581 can control is the number of inverters connected to the control unit 581 when the control panel 50 is powered on for the first time. It is determined by the number of inverter circuits (number of inverters) in the inverter 54. Once determined, it is initialized and will not be updated until the number of inverters connected to the control unit 581 is counted again. After counting the number of inverters, all the counted inverter circuits are allowed to operate (send control commands) within the control unit 581, but even the counted inverter circuits can be individually prohibited from operating. When prohibiting operation individually, a selection/stop button 535 for permitting/prohibiting the operation of each inverter circuit is provided for each inverter circuit, and by pressing the selection/stop button 535, the control unit 581 is configured to prohibit the operation of each inverter circuit. Toggle permission/prohibition for driving. Inverter circuits set to prohibited are not driven. That is, the control unit 581 does not issue a command to the inverter circuit set to be prohibited. Note that the configuration for permitting/prohibiting driving is not limited to whether or not a control command is issued. When prohibiting operation more safely, an inverter 54 is provided for each pump, and the control unit 581 is configured to be able to cut off power supply to each inverter 54. When prohibiting operation, the power is cut off, and when permission is granted, the power is turned on. Furthermore, driving may be prohibited for safety. In addition, in normal conditions, all inverter circuits (and therefore all pumps) are set to allow operation, but when performing maintenance, the operation of the pump subject to maintenance is prohibited, and the pump subject to maintenance is Perform maintenance while stopped. Note that after maintenance, it is necessary to reset the settings to allow operation of the pump targeted for maintenance.

In addition, the operation processing unit 582 controls the selection/stop LED lamp 566c for each pump so that the selection/stop LED lamp 566c is turned on when operation is permitted and turned off when operation is prohibited. Further, the operation processing unit 582 causes the display panel 562 to display operation prohibition information in place of the operation information or status information for each pump whose operation is prohibited. The driving prohibition information only needs to include character information indicating that driving is prohibited. For example, desired character strings such as "driving prohibited", "not set", "not selected", etc. can be used. It has become. In addition, the driving prohibition information can be displayed in the usual manner, displaying text information in a blinking manner, displaying a pattern on the background of the text information, or displaying a pattern on the background of the text information blinking. Either a display mode or a mode in which both the character information and the background pattern are displayed blinking may be used. The operation processing unit 582 displays operation prohibition information on the display panel 562, thereby prompting the operator to reset the operation of the pump after maintenance to permission.

The operation processing unit 582 also displays a screen that displays a list of operation information and status information for each pump, a screen that individually displays operation information or status information for each pump, and a screen that displays a list of operation information according to the operator's operation. A screen displaying the operation mode of the pump displayed or individually displayed is cyclically displayed on the display panel 562.

Here, for example, when the plurality of pumps includes a pump in a normal state and a pump in an abnormal state, the operation mode may represent a failure alternative operation of the pump in a normal state.

For example, if multiple pumps are in normal condition and eco-operation is being performed based on forced operation time to reduce the water temperature inside the pumps, the operation mode may be set to indicate the eco-operation. Good too. Note that eco-operation is a mode in which the operation of a pump that has been started is monitored and the pump is stopped at an optimal forced operation time. The forced operation time is a variable used for an interlock (protection mechanism) that forces a started pump to operate for a certain period of time. If the pump is started, the eco-operation occurs whether the pump is in a normal state or an abnormal state. As a supplement, when operating at a small water flow near the stop flow rate, the water flow inside the pump becomes small and high-temperature water stays inside the pump, causing excessive wear on the sliding parts of the shaft seal such as mechanical seals, causing the shaft to deteriorate. The life of the seal may be shortened. On the other hand, a protection mechanism that uses forced operation time prevents high-temperature water from accumulating in the pump by continuing to operate the pump for at least the forced operation time even if a stop flow rate is detected after the pump has started. This reduces wear on sliding parts. At this time, in the driving mode in which eco-driving is performed, the forced driving time is adjusted based on the maximum driving time and the previous driving stop time, thereby reducing unnecessary driving and saving power consumption. Note that the forced operation time is the time obtained by subtracting the previous operation stop time from the maximum operation time. That is, the shorter the previous operation stop time, the longer the forced operation time. Therefore, when the previous operation stop time is short and the heat inside the pump is relatively high, the forced operation time becomes long, so it is possible to reduce the temperature of the water inside the pump. A technique for reducing the temperature of water in the pump using such forced operation time is described in, for example, Japanese Patent No. 6,695,466.

For example, if a plurality of pumps are in a normal state and smooth operation is performed for each pump to smooth out the cumulative operating time of each pump, the operation mode may be set to represent the smooth operation. Good too. Note that the driving mode is not limited to the illustrated failure alternative driving, eco-driving, smooth driving, etc., and any mode can be used as appropriate.

For example, the operation processing unit 582 sets the manual operation mode and controls the operation switching LED lamp 567 to turn on in response to the operator's operation of the manual operation switching button 536a. Similarly, the operation processing unit 582 sets the operation of all pump units 60 to be prohibited and controls the operation switching LED lamp 567 to turn on in response to the operator's operation of the all stop button 536b. Similarly, the operation processing unit 582 sets the automatic driving mode and controls the lighting of the driving switching LED lamp 567 in response to the operator's operation of the automatic driving switching button 536c. The operation processing section 582 is an example of a setting section and a display control section.

The communication unit 583 transmits any of operation information, status information, and operation prohibition information to the management device 1 for each pump. Furthermore, the communication unit 583 may transmit error information to the management device 1 when the display of the driving prohibition information continues for a certain period of time or more. As the error information, for example, an identification code related to an error in which the driving prohibition information continues to be displayed for a certain period of time or more, a character string indicating the error, or both can be used as appropriate.

Note that the number of boards constituting the control panel 50 can be arbitrarily designed, and each board has a short range communication device 51, a long distance communication device 52, an input device 53, an inverter 54, an interface 55, a display device 56, and a storage device. 57 and the processor 58 to be physically installed can be arbitrarily designed. Further, although the control unit 581, the operation processing unit 582, and the communication unit 583 are assumed to be handled by one processor 58, they may be handled by a plurality of physically separated processors.

Next, an example of the operation of the pump device 5 and the management device 1 according to the present embodiment will be described with reference to the flowchart of FIG. 5 and the schematic diagrams of FIGS. 6 to 11.

First, in the pump device 5, the communication unit 583 periodically or irregularly transmits any of operation information, status information, and operation prohibition information to the management device 1 for each pump.

In the management device 1, the communication unit 15 receives any of the transmitted operation information, status information, and operation prohibition information from the pump device 5 for each pump. In addition, in the management device 1, the control unit 16 stores, for each pump, the received operation information, status information, and operation prohibition information, and the reception time in the database 14 as log data.

In such a pump device 5, the control unit 581 determines whether each pump is operating in a normal state. Further, based on the determination result, the control unit 581 causes the display panel 562 to display operating information for each pump when the pump is in a normal state. For example, when stopped in a normal state, the display panel 562 displays the operating information of pump No. 1 of the pump unit 60 at a frequency of 0.0 Hz and the operating information of pump No. 2, as shown in FIG. A list of frequencies 0.0Hz and 0.0Hz is displayed. Furthermore, the 7-segment LED 561 displays a code "H 37" indicating a normal state. Further, the operation LED lamp 566a is off, indicating that the pump No. 1 and the pump No. 2 are in a stopped state. Furthermore, the failure LED lamp 566b is off, indicating that pump No. 1 and pump No. 2 are in a normal state. Further, the selection/stop LED lamp 566c is lit, indicating a state in which operation of pump No. 1 and pump No. 2 is permitted.

Subsequently, in the pump device 5, it is assumed that the operation of the pump section 60 is started. At this time, the display panel 562 displays a list of the frequency 130.0 Hz, which is the operation information of the pump No. 1, and the frequency 130.0 Hz, which is the operation information of the pump No. 2. Further, the operation LED lamp 566a is lit, indicating the operating state (in operation) of the pump No. 1 and the pump No. 2.

Assume that after that, an overcurrent flows through pump No. 1 and pump No. 1 breaks down. At this time, the control unit 581 determines whether the operation of each pump is in a normal state or not, and obtains a determination result that pump No. 1 is in an abnormal state due to overcurrent. Further, the control unit 581 obtains a determination result that the pump No. 2 is in a normal state.

In step S10, based on the determination result that pump No. 1 is in an abnormal state of overcurrent, the control unit 581 controls the operation LED lamp 566a, the failure LED lamp 566b, the 7-segment LED 561, and the display panel as shown in FIG. 562 display control. Accordingly, in the operation LED lamp 566a, the upper LED is turned off in accordance with the abnormal state (operation stoppage) of pump No. 1. On the other hand, the upper LED of the failure LED lamp 566b lights up in response to the abnormal state (operation stoppage) of pump No. 1. Additionally, the 7-segment LED 561 displays the code "1-oC" in response to the overcurrent state of pump No. 1. Further, the display panel 562 displays text information "No. 1 overcurrent" depending on the overcurrent state of the No. 1 pump. After that, the reset button 533 is operated by the operator.

In step S20, the operation processing unit 582 resets the failure indications on the 7-segment LED 561 and the display panel 562 in response to the operation of the reset button 533. Accordingly, as shown in FIG. 8, the control unit 581 causes the 7-segment LED 561 to display the normal state code "H 37" and displays the status of each pump on the display panel 562. The display panel 562 displays a list of character information "OC" representing the type of abnormal condition (overcurrent) as state information of pump No. 1, and "frequency 130.0 Hz" as operating information of pump No. 2.

In step S30, the operation processing unit 582 displays a screen that displays a list of operation information and status information for each pump, a screen that individually displays operation information or status information for each pump, and a screen that displays operation information and status information for each pump, in response to the operator's operation. The display panel 562 cyclically displays a screen displaying the operation modes of the pumps displayed as a list or individually. Specifically, for example, the operation processing unit 582 performs switching display on the display panel 562 as shown in FIG. 9 in response to the operator's operation of the up/down button 534b. In FIG. 9, the topmost display panel 562 displays a list similar to the display panel 562 in FIG. 8. In addition, each time the up/down button 534b is operated, the display panel 562 displays a list display screen at the top, a screen with detailed information of the first unit "OC, overcurrent failure stopped", and a screen with the operating information of the second unit "2". .34A, 172V, 2.34kW" screen, the screen for the power supply voltage of the No. 2 inverter 54 "200.1V", and the screen for the operation mode "Failure replacement operation in progress" are displayed cyclically. . In FIG. 9, the screen at the top corresponds to the list display screen, and the second to fourth screens correspond to the individual display screens. Also, the bottom screen corresponds to the driving mode screen. The operation mode in this example represents a failure replacement operation for the pump in the normal state when the plurality of pumps includes a pump in the normal state and a pump in the abnormal state. Note that the failure replacement operation is the operation of pump No. 2, which has replaced the failed pump No. 1. In addition, in Figure 9, the screen transitions in one direction by operating the down button indicated by a downward triangle, but the screen is not limited to this; the screen transitions in the opposite direction by operating the up button indicated by an upward triangle. Good too. Thereafter, in order to prohibit the operation of the failed pump No. 1, the operator operates the upper selection/stop button 535 corresponding to pump No. 1.

In step S40, the operation processing unit 582 makes settings to permit or prohibit operation of each pump in accordance with the operation of the selection/stop button 535, and controls the operation/stop of each pump. For example, as shown in FIG. 10, the operation processing unit 582 controls the selection/stop LED lamp 566c to turn off the upper LED in accordance with the setting to prohibit the operation of pump No. 1. Further, the operation processing unit 582 causes the display panel 562 to display operation prohibition information instead of the status information for pump No. 1 whose operation is prohibited. Note that the normal state is basically a state in which the operation of all pumps is set to be permitted. That is, unless there is some kind of situation such as an abnormality or failure, operation of the pump is not prohibited. Therefore, if the prohibition setting is set due to an erroneous operation, or if the prohibition setting is maintained due to forgetfulness, a mechanism is required to alert the operator. Displaying the driving prohibition information on the display panel 562 is an example of this mechanism.

Thereafter, the operation processing unit 582 performs switching display on the display panel 562 as shown in FIG. 11 in response to the operator's operation of the up/down button 534b. In FIG. 11, the topmost display panel 562 displays a list similar to the display panel 562 in FIG. 10. In addition, each time the up/down button 534b is operated, the display panel 562 displays a list display screen at the top, a screen with detailed information on the No. 1 unit "operation prohibited, can be changed to operation permitted by pressing the selection stop button", and 2. Switch display between the detailed screen for the operating information of the unit ``2.34A, 172V, 2.34kW'', the screen for the power supply voltage ``200.1V'' of the inverter 54 of the second unit, and the screen for the operating mode ``Eco-driving''. Do it cyclically. The operation mode in this example represents eco-operation when a plurality of pumps are in a normal state and operation is performed based on forced operation time to reduce the water temperature inside the pumps.

In step S50, the operation processing unit 582 determines whether the pump has been stopped for a certain period of time or more since the operation was prohibited. For example, the operation processing unit 582 determines whether the stopped state of the pump continues by determining whether the display of the operation prohibition information continues for a certain period of time or more. Specifically, for example, the operation processing unit 582 starts counting from the time when displaying the driving prohibition information starts, and determines whether the count value exceeds a threshold value. If not, the operation processing unit 582 skips step S60 and ends the process. On the other hand, if the display of the driving prohibition information continues for a certain period of time or more, the operation processing unit 582 moves to step S60.

In step S60, the communication unit 583 is controlled by the operation processing unit 582 and notifies (sends) error information to the management device 1 when the display of the driving prohibition information continues for a certain period or more.

Thereby, in the management device 1, the communication unit 15 receives the error information from the pump device 5. The control unit 16 of the management device 1 reads from the database 14 notification destination information associated with the pump device 5 that transmitted the error information. The communication unit 15 of the management device 1 notifies the operator's terminal 3 of information regarding the error information based on the notification destination information. The information regarding error information includes, for example, error information and a message prompting a response to the error information. As a notification method, for example, e-mail, LINE, etc. can be used as appropriate.

The terminal 3 prompts the operator to cancel the setting that prohibits driving by displaying information regarding the notified error information. Thereafter, the operator returns to the site where the pump device 5 is installed, operates the selection/stop button, and makes settings to permit operation of the pump unit 60, which had been prohibited from operating. Thereafter, the pump device 5 operates each pump in a state where operation of all pumps is permitted.

As described above, according to the present embodiment, in the pump device 5, the control unit 581 determines whether the operation of each pump is in a normal state. For each pump, the control unit 581 causes the display panel 562 to display operating information when the pump is in a normal state, and causes the display panel 562 to display status information regarding an abnormal state when the pump is not in a normal state. The display panel 562 displays a list of operating information and status information for each pump. In this way, by displaying a list of operating information and status information for each pump, it is possible to reduce the effort required to confirm the status of each pump.

As a supplement, conventional pump devices separately display the state indicated by the operation information of each pump and the state indicated by the failure type of each pump. For this reason, in the conventional pump device, when confirming the state indicated by the operation information of each pump and the state indicated by the failure type of each pump, an operation is required for each state, which takes time and effort. Furthermore, when a pump cover is attached, it is time consuming to remove the pump cover in order to operate the operation panel of the control panel.

On the other hand, according to the pump device 5 of the present embodiment, the operation information and status information for each pump are displayed in a list, so that the operation for each status is not necessary, and the effort of operation can be reduced.

Further, according to the present embodiment, the pump device 5 further includes a failure LED lamp 566b for each pump, which is turned off when the condition is normal and turned on when the condition is not normal. Further, the status information is character information indicating the type of abnormal state of the lit failure LED lamp 566b. Therefore, in addition to the above-mentioned effects, when the failure LED lamp 566b is turned on, the type of abnormal condition that is the breakdown thereof can be displayed on the display panel 562.

Further, according to the present embodiment, in the pump device 5, the operation processing unit 582 makes settings for permitting or prohibiting operation of each pump in accordance with the operator's operation. The selection/stop LED lamp 566c lights up for each pump when operation is permitted, and turns off when operation is prohibited. Further, the operation processing unit 582 causes the display panel 562 to display operation prohibition information in place of the operation information or status information for each pump whose operation is prohibited. Therefore, in addition to the above-mentioned effects, the selection/stop LED lamp 566c and the display panel 562 each indicate the pump unit 60 whose operation is prohibited, so that the operator can easily recognize the pump whose operation is prohibited. be able to.

As a supplement, conventional pump devices have a design that allows you to select "Pump No. 1," "Pump No. 2," or "Pump No. 1/2" by rotating a rotary switch with a protruding indicator. This device makes it easy to recognize pump parts that are prohibited from operating. However, selection using a rotary switch does not take remote control into account, and when setting permission/prohibition for pump operation using remote control, there will be a discrepancy between the actual setting and the apparent setting of the rotary switch. However, on-site users may be confused.

On the other hand, in the pump device 5 of this embodiment, operation of each pump is permitted/prohibited by operating a substantially planar selection/stop button 535 and turning on/off the selection/stop LED lamp 566c for each pump. That's what I do. Accordingly, the pump device 5 of this embodiment is a device that is visually more difficult to identify a pump in an operation prohibited state than a conventional rotary switch. In consideration of this, the pump device 5 of the present embodiment is configured so that the selection/stop LED lamp 566c and the display panel 562 each indicate a pump whose operation is prohibited, so that it is easy to detect a pump whose operation is prohibited. so that it can be identified. Furthermore, by displaying operation prohibition information for each pump on the display panel 562, the operator can easily confirm that the pump is not stopped due to normal control but due to operation prohibition.

Further, according to the present embodiment, in the pump device 5, the communication unit 583 transmits any of the operation information, state information, and operation prohibition information to the management device 1 for each pump. Therefore, in addition to the above-mentioned effects, the management device 1 can manage any of the operation information, status information, and operation prohibition information for each pump. As a supplement, according to the present embodiment, the pump device 5 transmits the operation prohibition information for each pump to the management device 1, so the management device 1 can manage the operation prohibition information for each pump of the pump device 5. .

Further, according to the present embodiment, in the pump device 5, the communication unit 583 transmits error information to the management device 1 when the display of the operation prohibition information continues for a certain period or more. Therefore, in addition to the above-described effects, the management device 1 can detect an error in which the display of operation prohibition information on the pump device 5 side continues for a certain period of time or more.

Further, according to the present embodiment, in the pump device 5, the operation processing unit 582 displays a screen that displays a list of operation information and status information for each pump, and a screen that displays a list of operation information and status information for each pump, according to the operator's operation. A screen for individually displaying information and a screen for displaying the operation mode of the pump in which the operation information is displayed as a list or individually are displayed cyclically on the display panel 562. As a result, in addition to the above-described effects, the driving mode, which the user does not necessarily need to know, is displayed on a screen subsequent to the driving information and status information list display screen. Therefore, normal users do not have unnecessary questions about the driving mode that they do not necessarily need to know. In addition, an attentive user can learn the driving mode, which is not necessarily necessary, after repeating screen transition operations, and therefore does not need to make inquiries to the manufacturer regarding the driving mode.

Further, according to the present embodiment, when the plurality of pumps includes a pump in a normal state and a pump in an abnormal state, the operation mode represents a failure alternative operation for a pump in a normal state. Therefore, in addition to the above-mentioned effects, ordinary users do not have unnecessary questions regarding the operation mode "failure alternative operation" which they do not necessarily need to know. In addition, since a user with a high level of attentiveness learns about the driving mode "failure alternative driving" after repeating screen transition operations, there is no need to inquire about the driving mode to the manufacturer.

Similarly, according to the present embodiment, when a plurality of pumps are in a normal state and an eco-operation is being performed based on the forced operation time to reduce the water temperature in the pumps, the operation mode is set to Represents eco-driving. Therefore, in addition to the above-mentioned effects, ordinary users do not have unnecessary questions regarding the driving mode "eco-driving" which they do not necessarily need to know. In addition, since a user with a high level of attentiveness learns about the driving mode "eco-driving" after repeating screen transition operations, there is no need to inquire about the driving mode to the manufacturer.

Further, according to the present embodiment, in the management device 1, the database 14 stores the pump devices 5 and the notification destination information regarding the operator of the pump device 5 in association with each other. Further, when the communication unit 15 receives error information from the pump device 5, the control unit 16 reads notification destination information associated with the pump device 5 that transmitted the error information from the database 14, and based on the notification destination information. Then, information regarding the error information is notified to the terminal 3. As a result, in addition to the effects described above, the management device 1 can detect an error in which the display of operation prohibition information on the pump device 5 side continues for a certain period of time or more, and can notify the operator's terminal 3 of the error. .

As a supplement, when performing maintenance due to a failure of the pump section 60, the operation of the pump section 60 is set to be prohibited, and the pump section 60 is rendered inoperable. After maintenance, it is necessary to operate the selection/stop button 535 to permit operation again, but this operation may be forgotten. In the pump device 5 of this embodiment, the selection/stop LED lamp 566c and the display panel 562 each indicate the pump section 60 whose operation is prohibited, thereby prompting the cancellation of the operation prohibition. Even if you prompt them, there is a possibility that they will forget to cancel it.

However, according to the management device 1 of the present embodiment, it is possible to detect an error in which the display of operation prohibition information on the pump device 5 side continues for a certain period of time or more, and to notify the operator of the error to the terminal 3. We can strongly urge the lifting of the ban.

(Modified example)
In the present embodiment described above, for example, as shown in FIG. 8, the operation information (130.0 Hz) and status information (OC) for each pump are displayed in a list on the display panel 562 for two pumps, but the present invention is not limited to this. Not done. For example, a list of operation information and status information for each pump may be displayed on the display panel 562 for three or more pumps. For example, in the case of six pumps, the pump device 5 displays a screen displaying a list of pumps No. 1 and 2, a screen displaying a list of pumps No. 3 and 4, and a screen displaying a list of pumps No. This screen switches between displaying a list of units 5 and 6. Note that if the size of the display panel 562 is seven or more lines, a list of six pumps can be displayed on one screen. In any case, according to this modification, it is possible to display a list of operation information and status information for each pump for any plurality of three or more pumps.

Further, in the present embodiment, the pump device 5 transmits the error information to the management device 1 when the display of the operation prohibition information continues for a certain period of time or more, but the present invention is not limited to this. For example, the pump device 5 transmits any one of operation information, status information, and operation prohibition information to the management device 1 for each pump. In addition, the pump device 5 transmits the operation prohibition information to the management device 1 when the state information is changed to the operation prohibition information, and transmits the operation information to the management device 1 when the operation prohibition information is changed from the operation prohibition information to the operation information. You may also send it to In these cases, the management device 1 receives, for each pump, one of the transmitted operation information, status information, and operation prohibition information from the pump device 5 through the communication unit 15. In addition, the management device 1 stores, for each pump, any of the received operation information, status information, and operation prohibition information, and the reception time in the database 14 as log data. In addition, the management device 1 causes the control unit 16 to calculate the difference between the reception time of the driving prohibition information changed from the state information and the reception time of the driving information changed from the driving prohibition information based on the log data, Based on the difference, it is determined whether the display of the driving prohibition information has continued for a certain period of time or more. In addition, when the control unit 16 continues, the management device 1 outputs error information indicating the pump device 5 where the display of the operation prohibition information continues. Even in such a modification, the management device 1 can detect an error in which the display of operation prohibition information on the pump device 5 side continues for a certain period of time or more.

Further, in this modification, the management device 1 may store the pump device 5 and notification destination information regarding the operator of the pump device 5 in association with each other using the database 14. Similarly, the management device 1 causes the control unit 16 to read notification destination information associated with the pump device 5 indicated by the error information from the database 14, and based on the notification destination information, sends information related to the error information to the terminal 3. may be notified. Even in such a further modification, by having a configuration in which the detected error is notified to the operator's terminal 3, it is possible to strongly urge the operator to cancel the driving prohibition, as described above.

In addition, in the present embodiment described above, as shown in FIG. 9 or 11, the pump device 5 is operated in an unusual operation mode (e.g., failure replacement operation, Although eco-driving) is displayed on the display panel 562, the present invention is not limited thereto. For example, as shown in FIG. 12, the pump device 5 may display, on the display panel 562, an unusual operation mode (eg, smooth operation for cumulative operation time) in a normal state in response to a user's operation. In other words, the operation mode may represent smooth operation when a plurality of pumps are in a normal state and smooth operation is performed for each pump to smooth out the cumulative operating time of each pump. . For example, in the pump device 5, the control unit 581 controls the smooth operation of each pump so as to periodically smooth the cumulative operation time of each pump. In this case, for example, as shown in the top row of FIG. 12, the display panel 562 displays operating information "frequency 0 Hz" corresponding to the stop of pump No. 1 and operating information "frequency 150 Hz" corresponding to the operation of pump No. 2. is displayed. In addition, during the control of the smooth operation, the pump device 5 causes the control unit 581 to display the smooth operation information in response to the operation of the up/down button 534b by the user, instead of displaying a list of operation information and status information for each pump. A screen displaying text information representing driving is displayed on the display panel 562. In the example shown in the bottom row of FIG. 12, a screen representing "integrated operation time smooth operation" as the operation mode is displayed on the display panel 562. According to this modification, normally, Pump No. 1 and Pump No. 2 are operated alternately, but when Pump No. 2 is operated continuously, it is possible to update the cumulative operating time to indicate that the pump is in smooth operation. It can be displayed on the display panel 562 in response to the operation of the down button 534b. In addition, the screen indicating "cumulative operation time smooth operation" as the operation mode is displayed after repeating the screen transition from the screen displaying a list of operation information and status information for each pump, so users who repeatedly perform the screen transition operation The operating mode can be displayed. According to such a modification, a driving mode that the user does not necessarily need to know, such as "accumulated driving time smooth driving", is displayed on a screen after the driving information and status information list display screen. Therefore, if a normal user does not notice the continuous operation of the pump No. 2, he or she does not need to know the operation mode "cumulative operation time smooth operation", which is not necessarily necessary, and therefore there is no need to know about the continuous operation or the operation mode. You don't have to have any doubts. In addition, if an attentive user notices the continuous operation of pump No. 2, he or she may learn about the operation mode "accumulated operating time smooth operation", which is not necessarily necessary, after repeating the screen transition operation. Therefore, there is no need to make inquiries to the manufacturer regarding the continuous operation and its operation mode.

In the present embodiment and the modified example described above, the control unit 16 and processor 58 that execute several processes have been described, but this is only an example of implementation. For example, multiple processes described as being performed by one controller 16 and processor 58 may be implemented across multiple separate controllers and processors.

The various control units 16 described in the present embodiment and modified examples may be realized using circuits. The circuit may be a dedicated circuit that implements a specific function, or may be a general-purpose circuit such as a processor. Similarly, the functionality of processor 58 may be implemented with dedicated circuitry that implements specific functionality.
