[0009] Hereinafter, a pump management system according to an embodiment will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of a pump management system that manages pump devices 100-1 to 100-n according to an embodiment.

[0010] In this pump management system, a pump management device 200 manages pump devices 100-1 to 100-n through a mobile communication network NW. The mobile communication network NW is, for example, a network for a mobile phone system.

[0011] The pump devices 100-1 to 100-n are installed in an equipment room, for example, in the basement of a building or facility, and pump water stored in a water tank or purified water supplied from a main water pipe using a pump driven by the power of a motor. Note that the pump devices may be intended for liquids other than purified water.

[0012] In addition, there are various types of pumps suitable for the pump devices 100-1 to 100-n depending on the building or facility in which they are installed, but in the description of this embodiment, points common to all types of pump devices will be described as "pump device 100." In other words, when describing pump device 100, the description will be of the configuration and operation common to all pump devices 100-1 to 100-n.

[0013] As described in detail below, the pump device 100 is equipped with a long-distance communication function for wirelessly communicating with a base station BS of a mobile communication network NW, and a short-distance wireless communication function for wirelessly communicating with smartphones, tablet terminals, and laptop personal computers (notebook computers) carried by workers.

[0014] The base station BS is a base station device of a mobile communication system operated by a telecommunications carrier, and is primarily used for wireless communication with smartphones and mobile phones, but is also capable of communicating with communication units installed in various IoT (Internet of Things) devices, including the pump device 100, and connects these communication devices to the mobile communication network NW.

[0015] The gateway device GW is connected to the mobile communication network NW and serves as a network node that performs, for example, protocol conversion between the mobile communication network NW and the pump management device 200, and interconnects the mobile communication network NW and the pump management device 200.

[0016] The pump management device 200 monitors and manages the operational status of the pump devices 100-1 to 100-n, and is installed in the facilities of a monitoring and management business operator or the like, and collects and records information about the operational status of the pump devices 100-1 to 100-n, as well as performing remote control, via a gateway device GW and a mobile communication network NW.

[0017] Next, the pump device 100 will be described with reference to FIG. The pump device 100 includes a pump section 100P and a control panel 100C as main components.

[0018] The pump section 100P is equipped with one or more pump units, an accumulator, a water supply line connecting these, a check valve, and various sensors, and, for example, by controlling the power supplied from the control panel 100C, the liquid sucked in from the pump inlet on the primary side is pressurized and pumped out, and the liquid is delivered from the pump outlet on the secondary side.

[0019] The pump unit 100P may have various configurations, but since it may be any type of pump, whether it is a general type or a special type, details of the mechanism and operation thereof will be omitted. Furthermore, the pump unit 100P is not limited to the configuration described above.

[0020] The control panel 100C accepts instructions and settings from an operator and controls the operation of the pump unit 100P in accordance with those instructions and settings, and is equipped with a power supply circuit 110, a storage battery 111, a display unit 120, a long-distance communication unit 130, a short-distance communication unit 140, an operation unit 150, a communication connector 160, a sensor interface (I / F) 170, a memory unit 180, and a control unit 190.

[0021] The power supply circuit 110 is equipped with an inverter and converts the power supplied from the distribution board into AC power for driving the motor in the pump unit, and supplies the power, thereby having the function of controlling, for example, the pressure of the discharged liquid to a target pressure.

[0022] The storage battery 111 is for storing backup power for operating some functions of the control board 100C when power is not supplied from the distribution board due to a power outage or the like.

[0023] The display unit 120 is an example of an alarm unit, and is a display device using devices such as an LCD panel, an organic EL (Electro Luminescence) panel, a 7-segment LED, or an LED lamp, and visually displays and notifies information provided by the control unit 190 to workers, facility managers, etc.

[0024] The information displayed on the display unit 120 under the control of the control unit 190 includes information indicating the operating state and settings of the pump device 100, responses to input operations by the operator, processing results, etc. Note that, other than visual methods, information may be notified to the operator by sound (audio) or the like.

[0025] The long-distance communication unit 130 is a communication unit that complies with communication standards such as LTE (registered trademark) (Long-Term Evolution), 4G (4th Generation) or 5G (5th Generation), and communicates wirelessly with a base station BS and with the pump management device 200 via a mobile communication network NW and a gateway device GW.

[0026] In addition, the long-distance communication unit 130 has a mechanism and interface that can be attached and detached to the interface 131 connected to the control unit 190, and can be removed or replaced as necessary in the event of a malfunction, upgrade, or maintenance such as updating firmware or programs.

[0027] The long-distance communication unit 130 is equipped with a SIM (Subscriber Identity Module) as subscriber identification information for using a communication service provided by a communication carrier, and performs communication using the subscriber identification information. That is, in communication using the long-distance communication unit 130, a communication fee is charged by the communication carrier.

[0028] The SIM may be a SIM card or an eSIM (Embedded SIM). In the case of a SIM card, the communication unit has a card slot as an interface and a mechanism for enabling attachment and detachment (replacement).

[0029] Furthermore, in cases where the communications carrier identifies (specifies) the service subscriber by a method other than the SIM, a storage device is provided for storing identification information (ID information) according to that method.

[0030] The short-distance communication unit 140 is a communication unit that complies with communication standards such as Bluetooth (registered trademark), wireless LAN, and NFC (Near Field Communication), and performs direct wireless communication with various devices (personal computers, smartphones, tablet devices, and other communication devices) that are compatible with these communication standards. In other words, no communication costs are incurred in communication using the short-distance communication unit 140.

[0031] In addition, the short-range communication unit 140 has a mechanism and interface that can be attached and detached to the interface 141 connected to the control unit 190, and can be removed or replaced as necessary in the event of a malfunction, upgrade, or maintenance such as updating firmware or programs.

[0032] The operation unit 150 is a touch panel or a plurality of key switches provided on software keys displayed on the display unit 120 , and receives requests and instructions from an operator and transmits them to the control unit 190 .

[0033] In addition, the operation unit 150 may be equipped with a microphone in addition to the physical input means described above, so that the control unit 190 recognizes commands indicated by input voice and accepts requests and instructions from the operator.

[0034] The communication connector 160 is a connector for connecting a communication cable (serial cable) conforming to a serial communication standard such as RS-232C, and is used for connecting a control device such as a personal computer for control and information input. Note that the function as a communication interface for transmitting and receiving signals is provided to the control unit 190.

[0035] The sensor interface 170 is an interface for connecting various sensors arranged inside (or outside) the pump device 100, and supplies operating power to each sensor, as well as providing instructions from the control unit 190 to the various sensors, and transmitting information (detection results) detected by the various sensors to the control unit 190.

[0036] In FIG. 2, a water leakage sensor 171, a pressure sensor 172, a flood sensor 173, and a flow rate sensor 174 are shown as examples of sensors, but sensors other than these may be provided and information detected by each sensor may be input to the control unit 190 via the sensor interface 170.

[0037] The water leakage sensor 171 detects water leakage from around the pump unit 100P. The pressure sensor 172 detects the pressure of the liquid pumped by the pump section 100P. The flood sensor 173 detects that flooding has occurred around the pump device 100 due to flooding or the like. Flow sensor 174 detects the amount of liquid being pumped by pump portion 100P.

[0038] The storage unit 180 uses a semiconductor memory such as a Synchronous Dynamic RAM (SDRAM), a NAND flash memory, or an Erasable Programmable ROM (EPROM).

[0039] The storage unit 180 stores a control program and control data for the control unit 190. As one piece of control data, the storage unit 180 also stores a control table 180a, and stores an operation log of the pump device 100 as log data 180b.

[0040] The control table 180a is a data table used for processing to manage information such as the operating status and operation log of the pump device 100, and as illustrated in FIG. 3, various states of the pump device 100 are associated with settings for judgment conditions for determining each state, corresponding processing to be performed in response to each state, and recording of operation logs.

[0041] The log data 180b may include detection results of various sensors, various settings and setting values ​​of the pump device 100, schedule information for various operations, failure history indicating the occurrence of a failure (such as the part and time where the failure occurred), a history of operations performed by operators (the content of the operation and the time when the operation was performed), the state of the pump and information used when determining that state (for example, sensor detection results, etc.).

[0042] The control unit 190 controls each unit of the control panel 100C and includes a processor and a memory. The memory stores the control program and control data read from the storage unit 180, and the processor executes the control program and performs various controls and processes according to the control data. In other words, the control unit 190 is also an example of a determination unit, a notification control unit, and a storage control unit.

[0043] In the above control and processing, the control unit 190 receives instructions from an operator, and controls each part of the pump device 100 in accordance with the instructions, for example, performing automatic operation control, monitoring processing, and the like.

[0044] Automatic operation control includes, for example, switching the operating frequency, starting and stopping the pump according to the time of day, pressure control so that the water supply pressure is constant at a target value, or control so that the amount of water supply per unit time is constant.

[0045] The monitoring process includes notifications according to instructions from the outside, collection of detection results from various sensors, and determination of the state of the pump device 100 and various response processes based on the detection results and the control table 180a.

[0046] The control unit 190 has a clock function for measuring the current time. The control unit 190 may also be configured to have an ASIC (Application Specific Integrated Circuit) for performing specific processes (such as clock functions, communication control, display control, input reception process, etc.) and to operate in cooperation with the above processor.

[0047] The control unit 190 may also be configured to be composed of one or more circuit boards, and have a mechanism for easy attachment and detachment to a slot connected to the control bus of the control board 100C, so that it can be removed or replaced as necessary in the event of a malfunction, upgrade, or maintenance such as updating firmware or programs.

[0048] Next, the pump management device 200 will be described with reference to FIG. The pump management device 200 includes an operation unit 210, a display unit 220, a storage unit 230, a database 240, a pump communication unit 250, and a control unit 260.

[0049] The operation unit 210 is a keyboard, a mouse, or the like, and receives requests and instructions from an operator and transmits them to the control unit 260 . The display unit 220 is a display device using a device such as a liquid crystal panel, an organic EL panel, a 7-segment LED, or an LED lamp, and visually displays information provided from the control unit 260 to the operator.

[0050] The storage unit 230 uses a semiconductor memory such as an SDRAM, a NAND flash memory, or an EPROM, and stores the control program and control data of the control unit 260.

[0051] The database 240 is a storage device having a relatively larger storage capacity than the storage unit 230, and includes a storage medium such as a semiconductor memory or a HDD (Hard Disk Drive). The database 240 prestores a management table 240a and is used to store log data 240b.

[0052] The management table 240a is a data table for managing whether or not notification and recording are to be performed on each pump device 100 for the pump devices 100-1 to 100-n managed by the pump management device 200, and for each pump device 100-1 to 100-n, as shown in FIG. 5, for example, a pump notification setting indicating whether or not to notify the pump device 100 and a pump recording setting indicating whether or not to cause the pump device 100 to record an operation log are stored in association with various states of the pump device 100.

[0053] Each of these settings may be preset to any content depending on the skill level of the manager of the building or facility in which the pump device 100 is installed, or on the request of the manager or the like. The log data 240b is the log data received from the pump device 100.

[0054] The pump communication unit 250 communicates with the pump device 100 through the gateway device GW and the mobile communication network NW.

[0055] The control unit 260 includes a processor and a memory. The memory stores the control program and control data read from the storage unit 230, and the processor executes the control program and performs various controls and processes according to the control data. The control unit 260 is an example of a transmission control unit, and also includes a clock function for measuring the current time.

[0056] In the above control and processing, the control unit 260 receives instructions from an operator and controls each part of the pump management device 200 in accordance with those instructions, and performs management processing at preset times or at periodic timings.

[0057] The management process transmits log data 240b (or a part of it) to the pump device 100 and controls notifications on the pump device 100 in accordance with the management table 240a.

[0058] Next, a description will be given of the operation of the pump device 100 having the above-mentioned configuration. In the following description, the monitoring process will be particularly described, and a description of the pumping mechanism for supplying water in the pump device 100 and its operation will be omitted.

[0059] FIG. 6 is a flowchart of the monitoring process by the pump device 100. This monitoring process is performed by the control unit 190.

[0060] In the following description, the monitoring process is described as being started when the power of the pump device 100 is turned on and operation starts, but it may be started appropriately in response to an instruction from an operator. In addition, a timer starts counting with the start of the monitoring process.

[0061] In step S601, the control unit 190 determines whether or not management device notification information has been received from the pump management device 200 through the long-distance communication unit 130. If the management device notification information has been received, the process proceeds to step S602. On the other hand, if the management device notification information has not been received, the process proceeds to step S603.

[0062] In step S602, the control unit 190 notifies the state of the pump device 100 based on the management device notification information received from the pump management device 200, and then proceeds to step S603.

[0063] More specifically, the control unit 190 controls the display unit 120 to perform a display based on the management device notification information, and notifies the state of the pump device 100 to a facility manager, workers, or the like.

[0064] The status of the pump device 100 that may be notified here may be, for example, "water leakage," "flooding," "insufficient water supply performance," or "possible water outage," as shown in FIG. 3, but the actual status that is notified will be in accordance with the settings in the management table 240a.

[0065] As a result, a facility manager, worker, or the like, who sees the information displayed on the display unit 120, can understand the state of the pump device 100. Note that the state may be notified by voice, warning sound, or the like in addition to the display.

[0066] Furthermore, when log data is included in the management device notification information, this log data is stored as log data 180b in the storage unit 180. The log data 180b stored in the storage unit 180 can be displayed on the display unit 120 in response to an arbitrary operation through the operation unit 150, and can be viewed by a facility manager or the like. Furthermore, the log data 180b can be transmitted to a device carried by a worker through the short-range communication unit 140 and displayed, so that the worker can also view it on the device.

[0067] In step S603, the control unit 190 refers to the count value of the timer or the time measured by the clock, and determines whether or not a preset timing (period or time) for acquiring the detection result of the sensor has arrived.

[0068] If the timing (cycle or time) for acquiring the detection result of the sensor has arrived, the process moves to step S604, whereas if the timing has not arrived, the process moves to step S601.

[0069] In step S604, the control unit 190 acquires detection results from various sensors (such as the water leakage sensor 171, pressure sensor 172, flood sensor 173, and flow rate sensor 174) through the sensor interface 170, detects the time of the detection, generates log data that associates the detection results with information such as the time and operation settings, and then proceeds to step S605. Note that the cycle and time for acquiring the detection results may be set differently for each sensor.

[0070] In step S605, the control unit 190 compares the information on the operating state and the detection result acquired in step S604 with the control table 180a to determine the state of the pump device 100, and proceeds to step S606. An example of determining the state of the pump device 100 will be described below using the control table 180a as shown in FIG.

[0071] For example, when the water leakage sensor 171 detects water leakage, the state of the pump device 100 is determined to be "water leakage." When the water inundation sensor 173 detects water inundation, the state of the pump device 100 is determined to be "water inundation."

[0072] Also, for example, if the pressure sensor 172 detects a pressure below the target value, the operation frequency is at its maximum due to operation control by the control unit 190, and the flow rate sensor 174 detects a continuous flow rate above the threshold value, the state of the pump device 100 is determined to be "insufficient water supply performance."

[0073] On the other hand, for example, if the pressure sensor 172 detects a pressure below the target value, the operation frequency is at its maximum due to operation control by the control unit 190, and the flow sensor 174 detects a continuing flow rate below the threshold, the state of the pump device 100 is determined to be "possible water outage."

[0074] In step S606, the control unit 190 performs a response process corresponding to the state determined in step S605, and the process proceeds to step S607. The response process to be performed will be described below using an example in which the control table 180a is as shown in FIG.

[0075] For example, if a "leak" is determined in step S605, since "full notification" is set as the response process, the control unit 190 controls the display unit 120 to notify the facility manager or the like of the occurrence of a leak, generates status information including notification information indicating that the pump device 100 is in a "leak" state and the log data generated in step S604, and controls the long-distance communication unit 130 to send the status information to the pump management device 200, thereby notifying the outside.

[0076] Similarly, for example, if "flooding" is determined in step S605, since "full notification" is set as the response processing, the control unit 190 controls the display unit 120 to notify the facility manager or the like of the occurrence of flooding, generates status information including notification information indicating that the pump device 100 is in a "flooded" state and the log data generated in step S604, and controls the long-distance communication unit 130 to send the status information to the pump management device 200, thereby notifying the outside.

[0077] Furthermore, for example, if it is determined in step S605 that “water supply performance is insufficient,” then since “external notification” is set as the response process, the control unit 190 does not issue an alert on the pump device 100, but instead generates status information including notification information indicating that the pump device 100 is in a state of “water supply performance insufficiency” and the log data generated in step S604, and controls the long-distance communication unit 130 to transmit the status information to the pump management device 200, thereby notifying the outside.

[0078] Furthermore, for example, if it is determined in step S605 that "there is a possibility of a water outage," since "self-recovery processing" is set as the response processing, the control unit 190 performs a self-recovery processing for the water outage by first stopping operation of the pump unit 100P, and then resuming operation after a certain period of time, and executes a confirmation process to confirm whether there is a water outage.

[0079] If this confirmation process causes the flow sensor 174 to detect a flow rate equal to or greater than a preset threshold level, the control unit 190 determines that there is no longer any suspicion of water outage and continues operation, while generating status information including notification information indicating this progress and the log data generated in step S604, and controls the long-distance communication unit 130 to transmit the status information to the pump management device 200, thereby notifying the outside. Note that no notification is made on the pump device 100 itself.

[0080] On the other hand, if the flow sensor 174 does not detect a flow rate above the threshold level even after performing the above confirmation process a preset number of times, the control unit 190 stops operation of the pump unit 100P to prevent overheating, etc., controls the display unit 120 to notify the facility manager or the like of the occurrence of a water outage, generates status information including notification information indicating that the pump device 100 is in a ``water outage'' state and the log data generated in step S604, and controls the long-distance communication unit 130 to send the above status information to the pump management device 200, thereby notifying the outside.

[0081] The status information includes information on whether or not a notification about the status has been made (or can be made) by the pump device 100, and information on whether or not the information used to determine the status has been recorded by the pump device 100. These pieces of information are generated by the control unit 190 based on parameters set in "Response Processing" and "Pump Internal Recording" in the control table 180a.

[0082] In step S607, the control unit 190 performs a recording process according to the parameters of "recording in pump" corresponding to the state determined in step S606, and proceeds to step S601. The recording process to be performed will be described below using an example in which the control table 180a is as shown in FIG.

[0083] For example, if a “leak” or “flooding” is determined in step S605, the “pump internal recording” parameter is set to “ON”, so the control unit 190 records the status information generated in step S605 in the memory unit 180 as log data 180b.

[0084] On the other hand, if it is determined in step S605 that there is “insufficient water supply performance” or “possibility of water outage,” the “recording inside the pump” parameter is set to “OFF,” so the control unit 190 does not record the status information generated in step S605 in the memory unit 180.

[0085] Next, the operation of the pump management device 200 having the above configuration will be described. In the following description, the management process will be particularly described. Fig. 7 is a flowchart of the management process by the pump management device 200. This management process is executed by the control unit 260 when the pump communication unit 250 receives a notification from the pump device 100.

[0086] In step S701, the control unit 260 receives, via the pump communication unit 250, the status information transmitted by the response process in step S606, and detects the identification information of the pump device 100 that transmitted the status information, and then proceeds to step S702.

[0087] In step S702, the control unit 260 associates the log data included in the status information received in step S701 with the identification information of the pump device 100 detected in step S701, records the log data in the database 240 as log data 240b, and proceeds to step S703.

[0088] In step S703, the control unit 260 notifies the operator of the pump management device 200 of the state of the pump device 100 based on the notification information included in the state information received in step S701, and proceeds to step S704.

[0089] The states of the pump device 100 that are notified to the operator include "water leakage," "flooding," "insufficient water supply performance," and "possible water outage," as exemplified in FIG.

[0090] In step S704, the control unit 260 refers to the management table 240a of the pump device 100 corresponding to the identification information detected in step S701, checks the pump notification setting for the status indicated by the notification information included in the status information received in step S701, and if it is "ON", proceeds to step S705, and if it is "OFF", terminates the process.

[0091] In step S705, the control unit 260 refers to the management table 240a of the pump device 100 corresponding to the identification information detected in step S701, checks the pump record setting for the state indicated in the notification information included in the status information received in step S701, and if it is "ON", proceeds to step S706, and if it is "OFF", proceeds to step S707.

[0092] In step S706, the control unit 260 generates management device notification information including the status information received in step S701, and transmits this management device notification information via the pump communication unit 250 to the pump device 100 corresponding to the identification information detected in step S701, and then terminates the processing.

[0093] Here, if the status information received from the pump device 100 includes information indicating that the pump device 100 has notified the user of the status or information indicating that the pump device 100 has recorded the information used to determine the status, i.e., if the pump device 100 has already notified or recorded the user, the generation and transmission of the management device notification information may be canceled, or management device notification information regarding the notification or recording that has not been performed may be generated and transmitted.

[0094] In step S707, the control unit 260 generates management device notification information including notification information excluding log data from the status information received in step S701, and transmits this management device notification information via the pump communication unit 250 to the pump device 100 corresponding to the identification information detected in step S701, and terminates the processing.

[0095] Here, if the status information received from the pump device 100 includes information indicating that notification of the status has been made by the pump device 100, i.e., if notification has already been made by the pump device 100, the generation and transmission of the above-mentioned management device notification information may be stopped.

[0096] A more specific description will now be given with reference to FIG. If the status information notification information received in step S701 indicates that the status of the pump device 100 is “insufficient water supply performance”, then since the “pump notification setting” is “OFF”, the result in step S704 is “No”, and the process is terminated.

[0097] As a result, no notification is sent from the pump management device 200 to the pump device 100, and therefore the pump management device 200 does not initiate any notification or record any log data regarding the “insufficient water supply performance” on the pump device 100.

[0098] That is, by setting the "pump notification setting" for a desired state to "OFF" in the management table 240a, unnecessary notifications can be prevented from being sent to a facility manager (e.g., a manager without high skills).

[0099] On the other hand, if the status information notification information received in step S701 indicates that the status of the pump device 100 is "possible water outage," then since both the "pump notification setting" and the "pump record setting" are "ON," the results are judged as "Yes" in both steps S704 and S705, and the process proceeds to step S706.

[0100] As a result, management device notification information including log data will be sent from the pump management device 200 to the pump device 100, and on the pump device 100, a notification of "possibility of water outage" and recording of log data will be sent in response to the action of the pump management device 200.

[0101] In other words, by setting both the "pump notification setting" and the "pump record setting" to "ON" for the desired state in management table 240a, the necessary notifications will be made to the facility manager (e.g., a highly skilled manager).

[0102] As described above, in this embodiment, the pump device 100 judges its own state according to the preset control table 180a, and selectively notifies the state according to the state. In this selective notification, notification on any of the pump device 100 and the pump management device 200 can be preset.

[0103] Therefore, according to the pump device 100, it is possible to prevent notifications intended for workers or other people with specialized knowledge from being sent to non-specialists such as facility managers, and therefore to avoid unsettling the owner or manager by providing unnecessary information. In other words, it is possible to selectively provide necessary information according to the state of the pump device 100, and therefore unnecessary information can be suppressed and necessary information can be easily accessed.

[0104] In addition, in the pump management system of the above embodiment, when the pump management device 200 receives a status notification from the pump device 100, it selectively notifies the pump device 100 depending on the notified status in accordance with a pre-configured management table 240a, and the pump device 100 that receives this notification notifies the status.

[0105] Therefore, according to the pump management system, notifications in the pump devices 100 can be controlled for each pump device 100 managed by the pump management device 200. Although the owners and managers of facilities in which the pump devices 100 are installed have different levels of expertise, notifications suitable for the facility in which the pump devices 100 are installed (or the manager of the facility) can be made by changing the settings of the management table 240a as necessary.

[0106] In addition, in this embodiment, the pump device 100 determines its own status according to a pre-set control table 180a and transmits an operation log to the pump management device 200 depending on the status, and the pump device 100 records or does not record the operation log depending on the status.

[0107] Therefore, according to the pump device 100, it is possible to prevent the recording of information that is not generally required and is intended for persons with specialized knowledge, such as workers, and it is possible to prevent the unnecessary recording of unnecessary information, which makes it difficult for owners, managers, etc. to access necessary information.

[0108] In addition, in the pump management system of the above embodiment, the pump management device 200 transmits the operation log received from the pump device 100 to the pump device 100 depending on the state of the pump device 100 in accordance with the pre-configured management table 240a, and the pump device 100 records this.

[0109] Therefore, according to the pump management system, the recording of information such as the operation log of the pump device 100 can be controlled for each pump device 100 managed by the pump management device 200. Although the owners and managers of the facilities in which the pump devices 100 are installed have different levels of expertise, by changing the settings of the management table 240a as necessary, it is possible to set recording settings suited to the facility (manager).

[0110] It should be noted that the present invention is not limited to the above-described embodiment as it is, and in the implementation stage, the components can be modified and embodied without departing from the gist of the invention. In addition, various inventions can be formed by appropriately combining multiple components disclosed in the above-described embodiment. For example, a configuration in which some components are deleted from all the components shown in the embodiment can also be considered. Furthermore, the components described in different embodiments may be appropriately combined.

[0111] For example, in the above embodiment, the pump device 100 communicates with the pump management device 200 through a mobile communication network NW, but the present invention is not limited to this. For example, the present invention can also be applied to a case where the pump device 100 communicates with the pump management device 200 through a communication device connected to the communication connector 160. The communication device may be a wired communication device or a wireless communication device.

[0112] In the above embodiment, as described with reference to FIG. 7, even if the pump device 100 is configured not to notify or record in the control table 180a, the pump management device 200 may 40 It has been described that notification and recording on the pump device 100 are controlled based on a.

[0113] Alternatively or in addition, for example, in the pump management device 200, the control unit 260 receives an instruction from the operator via the operation unit 210 regarding changing the notification and recording settings in the pump device 100, and transmits the instruction to the pump device 100 via the pump communication unit 250. That is, the control unit 260 functions as an instruction transmission unit.

[0114] In the pump device 100, the control unit 190 receives the above instruction via the long-distance communication unit 130, and changes the settings for notification and recording in the control table 180a in response to the instruction. That is, the control unit 190 functions as a change unit.

[0115] Then, in the pump device 100, in accordance with the settings of the changed control table 180a, a notification is given according to the state of the pump device 100, as described with reference to the flowchart of FIG.

[0116] According to this, for example, in a case where the manager and the owner of the pump device 100 are different, in order to respond to a request to display on the pump device 100 before a notification from the pump device 100 to the pump management device 200, the setting can be changed as described above from the pump management device 200. The above-mentioned changes to the notification and recording settings on the pump device 100 from the pump management device 200 may be made via the Web. The Web input screen may be provided by the pump management device 200 itself, or may be provided by the pump device 100 accessed by the pump management device 200. It goes without saying that various modifications can be made without departing from the spirit and scope of the present invention. [Explanation of symbols]
