Description

An embodiment of the invention relates to a pump device that supplies liquid and a computer program that communicates with the pump device.

Recently, in the field of pump equipment maintenance, maintenance personnel are aging and there is a shortage of successors, so there is a demand for equipment monitoring from remote locations.
However, when monitoring equipment from a remote location, it is more difficult to accurately diagnose pump equipment, such as determining whether a failure has occurred, determining its cause, detecting anomalies before they occur, and discovering incorrect settings, compared to when an operator is on-site.

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 including pump devices 100-1 to 100-n according to an embodiment.

In this pump management system, the pump management device 200 manages the pump devices 100-1 to 100-n through a mobile communication network NW, and each of the pump devices 100-1 to 100-n can communicate directly with an external device 300 carried by an operator via short-range wireless communication. The mobile communication network NW is, for example, a public communication network such as a mobile phone system network.

Pump devices 100-1 to 100-n are installed in equipment rooms, 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 pump devices may also be used for liquids other than purified water.

In addition, there are various types of pump devices 100-1 to 100-n that are suitable for the building or facility in which they are installed, but in the description of this embodiment, points that are 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 that are common to all pump devices 100-1 to 100-n.

The base station BS is a base station device of a mobile communication system operated by a telecommunications carrier, and mainly communicates wirelessly with smartphones and mobile phones, but can also communicate with communication units installed in various IoT (Internet of Things) devices, including pump devices 100-1 to 100-n, and connects these communication devices to the mobile communication network NW.

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.

The pump management device 200 monitors, manages, and remotely controls the operational status of the pump devices 100-1 to 100-n. For example, it is installed at the facility of a monitoring and management company, and collects and records information on the operational status of the pump devices 100-1 to 100-n as well as remotely controls them via a gateway device GW and a mobile communication network NW.

The external device 300 is a portable information device carried by an operator, such as a smartphone, tablet terminal, or laptop personal computer (notebook computer), that has wireless communication and information processing capabilities, and like the pump management device 200, is capable of collecting and recording information about the operational status of the pump devices 100-1 to 100-n, as well as remote control.

In the example of FIG. 1, a worker is shown operating the external device 300. However, as described below, the external device 300 can be connected to the pump devices 100-1 to 100-n and can operate by receiving power supply, and can be operated autonomously even if a worker is not present at the installation site of the pump devices 100-1 to 100-n.

Next, the configuration of the pump devices 100-1 to 100-n will be described with reference to Fig. 2. In the following description, parts common to the pump devices 100-1 to 100-n will be described as the pump device 100.
The pump device 100 includes, as main components, a pump section 100P and a control panel 100C.

The pump section 100P supplies liquid and includes one or more pump units, an accumulator, a water supply line connecting these, a check valve, and various sensors. For example, by controlling the power supplied from the control panel 100C, the pump section 100P increases the pressure of the liquid sucked in from the pump suction port on the primary side, pumps it out, and delivers the liquid from the pump discharge port on the secondary side.

The pump unit 100P may take a variety of forms for each of the pump devices 100-1 to 100-n, but since it can be any type of pump, whether general or special, detailed descriptions of the mechanism and operation thereof will be omitted. Furthermore, the pump unit 100P is not limited to the configuration described above.

The control panel 100C receives instructions and settings from the operator and controls the operation of the pump unit 100P according to those instructions and settings, and has control functions according to the configuration of the pump unit 100P.

As shown in FIG. 2, the control panel 100C of the pump device 100-1 includes a power supply circuit 110, a storage battery 111, a mobile battery 112, an interface 113, a display unit 120, a long-distance communication unit 130, an interface 131, a short-distance communication unit 140, an interface 141, an operation unit 150, a communication connector 160, a sensor interface (I/F) 170, a memory unit 180, and a control unit 190.

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, thereby controlling the pressure of the discharged liquid to a target pressure, for example.

The power supply circuit 110 also has the function of converting the power supplied from the distribution board into DC power for charging the mobile battery 112.

The storage battery 111 is used to store backup power to operate some of the functions of the control panel 100C when power is not supplied from the distribution panel due to a power outage or other reason, and the power is supplied to the parts where it is needed via the power supply circuit 110.

The mobile battery 112 is a battery that supplies operating power to the external device 300 connected to the interface 113, and is charged by power supplied from the secondary side of the noise filter of the power supply circuit 110. Note that instead of the mobile battery 112, an adapter (or charger) that supplies operating power to the external device 300 may be provided.

In other words, by connecting the external device 300 to the mobile battery 112 via the interface 113, it becomes possible for the external device 300 to operate autonomously for a long period of time even when no operator is nearby, and as described in detail below, it collects information such as log data 180b and fault log data 180c from the pump device 100, and diagnoses and remotely controls the operating status.

The display unit 120 is a display device that uses devices such as a liquid crystal panel, an organic EL (Electro Luminescence) panel, a 7-segment LED, or an LED lamp, and visually displays and notifies the information provided by the control unit 190 to workers, facility managers, etc.

The information shown on the display unit 120 under the control of the control unit 190 includes information indicating the operational status and settings of the pump device 100, various log data, responses to input operations by the operator, processing results, etc. In addition to visual methods, information may be notified to the operator by sound (audio), etc.

The long-distance communication unit 130 is a communication unit that complies with a communication standard 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 and external device 300 via a mobile communication network NW and a gateway device GW.

The long-distance communication unit 130 also 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.

The long-distance communication unit 130 is equipped with a SIM (Subscriber Identity Module) as subscriber identification information for using communication services provided by a telecommunications carrier, and performs communication using the subscriber identification information. In other words, when communication is performed using the long-distance communication unit 130, a communication fee is charged by the telecommunications carrier.

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 that serves as an interface and has a mechanism that allows the card to be attached and detached (replaced).

In addition, if the telecommunications carrier identifies (specifies) the service subscriber by a method other than the SIM, the device is provided with a storage device that stores the identification information (ID information) according to that method.

The short-range communication unit 140 is a communication unit that complies with communication standards such as Bluetooth (registered trademark) and wireless LAN, 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 when communicating using the short-range communication unit 140.

The short-range communication unit 140 also 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.

The operation unit 150 is a touch panel or multiple hard switches (select switches) provided on the software keys displayed on the display unit 120, and receives requests and instructions from the operator and transmits them to the control unit 190.

For example, one of the select switches is used to set the operation of the pump device 100, switching between "stop" and "standby". When "stop" is set, the pump unit P is not operated, and when "standby" is set, the pump unit P is in a state where it can be operated and is initially in a standby state, and when various conditions are met, the pump unit P is operated, and depending on the situation, it goes into standby again.

In addition to the input means for physical contact as described above, the operation unit 150 may also be equipped with a microphone so that the control unit 190 can recognize commands indicated by input voice and accept requests and instructions from the worker.

The communication connector 160 is a connector for connecting a communication cable (serial cable) that complies with serial communication standards such as RS-232C, and is used to connect a control device such as a personal computer for control and information input, or to connect a high-precision measuring instrument (external sensor) for high-precision measurements, for example, at the time of shipment. The function of the communication interface for sending and receiving signals is provided by the control unit 190.

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, and also gives instructions from the control unit 190 to the various sensors, or transmits information (detection results) detected by the various sensors to the control unit 190.

In FIG. 2, a water leak sensor 171, a pressure sensor 172, a flood sensor 173, and a flow rate sensor 174 are shown as examples of sensors, but other sensors (e.g., higher accuracy sensors) may be provided and information detected by each sensor may be input to the control unit 190 via the sensor interface 170.

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.
The flow sensor 174 detects the amount of liquid being pumped by the pump portion 100P.

The memory unit 180 uses semiconductor memory such as SDRAM (Synchronous Dynamic RAM), NAND flash memory, or EPROM (Erasable Programmable ROM).

The memory unit 180 stores the control program and control data of the control unit 190. It also stores a control table 180a as one piece of control data, and can store multiple pieces of log data 180b and failure log data 180c as data collected and generated by the control unit 190.

The control table 180a is data that associates setting values for controlling the pump unit 100P, range information indicating the standard acceptable range of these setting values, and judgment values for detecting faults, including failures, based on the detection results of the sensors with the names of the faults or failures and the fault identifiers that indicate them.

Log data 180b is data that associates the detection results of various sensors and the logs of information detected by the control unit 190 (state of each part in the pump device 100, operation settings for the pump device 100, and operations by the operator) over a specified period of time with a time. Information detected by the control unit 190 includes inverter information (current value, voltage value, frequency, etc.), settings for opening and closing various valves, control settings (automatic/manual), settings of the select switch by the operator, etc.

In order to prevent the storage capacity of the storage unit 180 from becoming too full, the control unit 190 performs control to overwrite and store the log data 180b so that only the latest specified number of pieces are stored. In addition, the control unit 190 can read the log data 180b from the storage unit 180 and display it on the display unit 120 in response to an instruction from an operator via the operation unit 150.

The fault log data 180c is data that compiles the above log data 180b detected before and after the time of occurrence of various faults, including breakdowns, and is generated by the control unit 190.

The type of fault, the time of occurrence, an individual identifier (described later), and the like are added to the fault log data 180c by the control unit 190. Furthermore, the fault log data 180c can be read out from the memory unit 180 by the control unit 190 in response to an instruction from an operator via the operation unit 150, and displayed on the display unit 120.

The control unit 190 may also control the display so that information based on the detected facts and information determined (or estimated) based on this information are displayed in different colors to distinguish them from each other. This display control by the control unit 190 may be limited to color coding, as long as there is a visual difference, such as the type of font or between bold and thin characters.

In addition, the storage unit 180 stores an individual identifier as identification information uniquely given to the pump device 100 in order to distinguish the pump device 100 from others. This individual identifier is, for example, added to data transmitted to the pump management device 200 or the external device 300 and is used to indicate the source and attributes of the data, and is used for data management in the pump management device 200 and the external device 300. The individual identifier may be, for example, a serial number.

The control unit 190 controls all the parts of the control panel 100C and includes a processor and memory. The memory stores the control programs and control data read from the storage unit 180, and the processor executes the control programs and performs various controls and processes according to the control data. In other words, the control unit 190 is also an example of a log generation unit, detection unit, and erasure unit.

In the above control and processing, the control unit 190 receives instructions from the operator and controls each part of the pump device 100 in accordance with those instructions, for example, performing automatic operation control, generation of log data 180b, fault log generation processing, fault log transmission processing, diagnostic log transmission processing, etc.

Automatic operation control is based on pre-set settings or a pre-set schedule, and involves, for example, switching the operating frequency, starting and stopping the pump according to the time of day, controlling the pressure of the water supply so that it remains constant at a target value, or controlling the amount of water supply per unit time to be constant.

When a failure occurs, the failure log generation process generates log data 180b for the time the failure occurred and failure log data 180c that combines log data 180b before and after the failure based on the detection results of various sensors. Note that a failure is an example of an event.

The fault log transmission process controls the transmission of fault log data 180c to the pump management device 200 and external device 300, and erases data that has already been transmitted.

The diagnostic log transmission process controls the transmission of log data 180b to the pump management device 200 and external device 300 as diagnostic information for the pump device 100.

In addition, 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 (e.g., clock function, communication control, display control, input reception process, etc.) and to operate in cooperation with the above processor.

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

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 memory unit 230 , a database 240 , a pump communication unit 250 , and a control unit 260 .

The operation unit 210 is a keyboard, mouse, etc., that receives requests and instructions from the administrator and transmits them to the control unit 260.

The display unit 220 is a display device using devices such as a liquid crystal panel, an organic EL panel, a 7-segment LED, or an LED lamp, and visually displays information provided by the control unit 260 to the administrator. For example, the display unit 220 may display the detected state in a visually distinguishable manner under the control of the control unit 260. Also, for example, the display unit 220 may display the log data 240b and the detected state in a visually distinguishable manner under the control of the control unit 260.

The memory unit 230 uses semiconductor memory such as SDRAM, NAND flash memory, or EPROM, and stores the control program and control data of the control unit 260.

The database 240 is a storage device with a relatively larger storage capacity than the storage unit 230, and includes storage media such as semiconductor memory and HDD (Hard Disk Drive), and is used to pre-store the diagnostic table 240a and to store the log data 240b.

The diagnostic table 240a is a data table used when diagnosing the pump devices 100-1 to 100-n managed by the pump management device 200. Specifically, the data table includes information on the normal range of detection values of various sensors, setting values for controlling the pump unit 100P, tolerance range information showing the standard allowable range of these setting values, logs of setting values and operations (such as the settings of the select switch) when normal operation was performed in the past, whether remote operation (remote control) is possible (allowed/not allowed), and information on setting values based on special circumstances.

Log data 240b is log data 180b and fault log data 180c received from pump devices 100, and is stored so that it can be aggregated for each pump device 100-1 to 100-n.

The pump communication unit 250 communicates with the pump device 100 via the gateway device GW and the mobile communication network NW.

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 to perform 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 that keeps track of the current time. In other words, the control unit 260 is also an example of a reception control unit, a detection unit, a display control unit, a remote control unit, and a notification control unit.

In the above control and processing, the control unit 260 receives instructions from the administrator and controls each part of the pump management device 200 in accordance with those instructions, and performs management and diagnostic processing at preset times or periodically.

The management process stores the log data 180b and fault log data 180c sent from the pump device 100 as the log data 240b, and if the log data is not sent at the specified time, sends a message to the corresponding pump device 100 to prompt it to send the log data.

In addition, the management process may also request the pump device 100 to transmit log data at any time, or set a transmission time for the log data for the pump device 100.

The diagnostic process detects the occurrence of abnormalities, operational errors, and incorrect settings based on the data in the diagnostic table 240a and the log data 180b acquired from the pump device 100, and performs appropriate countermeasures (including remote control) for each case.

The external device 300 will be described with reference to FIG.
The external device 300 includes an operation unit 310 , a display unit 320 , a long-distance communication unit 330 , a short-distance communication unit 340 , a power supply circuit 350 , a battery 351 , a storage unit 360 , and a control unit 370 .

The operation unit 310 is a touch panel or key switch, etc., that receives requests and instructions from the operator and transmits them to the control unit 370.

The display unit 320 is a display device using a device such as a liquid crystal panel or an organic EL panel, and visually displays information provided by the control unit 370 to the administrator. For example, the display unit 320 may display the detected state in a visually distinguishable manner under the control of the control unit 370. Also, for example, the display unit 320 may display the log data 360b and the detected state in a visually distinguishable manner under the control of the control unit 370.

The long-distance communication unit 330 is a communication unit that complies with a communication standard such as LTE, 4G, or 5G, and communicates wirelessly with the base station BS and with the pump device 100 and the pump management device 200 via the mobile communication network NW and the gateway device GW.

The long-distance communication unit 330 is equipped with a SIM as subscriber identification information for using communication services provided by a communication carrier, and performs communication using the subscriber identification information. The SIM may be a SIM card or an eSIM.

The short-range communication unit 340 is a communication unit that complies with communication standards such as Bluetooth and wireless LAN, and performs direct wireless communication with various devices that support these communication standards (the pump device 100, a personal computer, a smartphone, a tablet device, and other communication devices).

The power supply circuit 350 transforms the power supplied from the AC adapter or mobile battery 112 or the built-in battery 251 as necessary, and supplies it as operating power to each part of the external device.

The memory unit 360 uses semiconductor memory such as SDRAM, NAND flash memory, or EPROM, and is used to store the control program and control data of the control unit 370, as well as to store the diagnostic table 360a and log data 360b.

The diagnostic table 360a is a data table used when the external device 300 diagnoses the pump devices 100-1 to 100-n that it diagnoses. Specifically, the data table includes information on the normal range of detection values of various sensors, setting values for controlling the pump unit 100P, tolerance range information showing the standard allowable range of these setting values, logs of setting values and operations (such as the settings of the select switch) when normal operation was performed in the past, whether remote operation (remote control) is possible (allowed/not allowed), and information on setting values based on special circumstances.

Log data 360b is log data 180b and fault log data 180c received from pump devices 100, and is stored so that it can be aggregated for each pump device 100-1 to 100-n.

The control unit 370 includes a processor and a memory. The memory stores the control program and control data read from the storage unit 360, and the processor executes the control program and performs various controls and processes according to the control data. The control unit 370 is an example of a transmission control unit, and also includes a clock function that keeps track of the current time. In other words, the control unit 370 is also an example of a reception control unit, a detection unit, a display control unit, a remote control unit, and a notification control unit.

In the above control and processing, the control unit 370 receives instructions from the administrator and controls each part of the external device 300 in accordance with those instructions, and performs management and diagnostic processing at preset times or periodically.

The management process stores the log data 180b and fault log data 180c sent from the pump device 100 as the log data 360b, and if the log data is not sent at the specified time, sends a message to the corresponding pump device 100 to prompt it to send the log data.

In addition, the management process may also request the pump device 100 to transmit log data at any time, or set a transmission time for the log data for the pump device 100.

The diagnostic process detects the occurrence of abnormalities, operational errors, and incorrect settings based on the data in the diagnostic table 360a and the log data 180b acquired from the pump device 100, and performs appropriate countermeasures (including remote control) for each case.

Next, the operation of the pump management system having the above configuration will be described.
First, the fault log generation process by the pump device 100 will be described with reference to Fig. 5. Fig. 5 is a flowchart illustrating the fault log generation process, which is performed by the control unit 190, and when a fault occurs, the control unit 190 detects the fault and generates log data for a certain period before and after the fault occurs as fault log data.

In the following explanation, the fault log generation process is described as being initiated when the pump device 100 is powered on and operation begins, but it may also be initiated as appropriate in response to instructions from an operator at any time.

In step S501, the control unit 190 acquires detection results from the various sensors 171-174 through the sensor interface 170, and proceeds to step S502. Note that if a high-precision sensor detection result is input to the communication connector 160, the control unit 190 also acquires this detection result.

In step S502, the control unit 190 detects the operational settings for the pump device 100 and the operator's operations (such as the settings of the select switch), generates a single piece of log data 180b that associates the current time with these detection results and the detection results of the various sensors acquired in step S501, saves the data in the memory unit 180, and proceeds to step S503.

In step S503, the control unit 190 determines whether the number of saved log data 180b exceeds a preset upper limit. If the upper limit is exceeded, the process proceeds to step S504. If the upper limit is not exceeded, the process proceeds to step S505.

In step S504, the control unit 190 erases the oldest log data 180b stored in the memory unit 180 that exceeds the upper limit, and then proceeds to step S505.

In step S505, the control unit 190 refers to the most recent log data 180b stored in the memory unit 180 to determine whether a fault has occurred in the pump device 100.

Specifically, the control unit 190 compares the sensor detection results contained in the latest log data 180b with the judgment value contained in the control table 180a to determine whether a fault has occurred. If a fault has occurred, the control unit 190 detects a fault identifier indicating the type or content of the fault associated with the judgment value used in the comparison, and identifies the fault that has occurred. Note that the judgment value is, for example, a threshold value that serves as a judgment criterion, and may be either an upper limit value, a lower limit value, or both. Such a judgment value is an example of criterion information that has been prepared in advance.

If it is determined that a failure has occurred, the process proceeds to step S506. On the other hand, if it is determined that no failure has occurred, the process proceeds to step S501.
In step S506, the control unit 190 repeatedly executes the same processes as in steps S501 and S502 a necessary number of times to generate and store log data 180b after the occurrence of a failure, and then proceeds to step S507.

In step S507, the control unit 190 reads from the memory unit 180 the log data 180b in which the occurrence of the fault was detected and the log data 180b generated before and after the occurrence, combines these data to generate fault log data 180c, stores the data in the memory unit 180, and proceeds to step S501.

Then, the control unit 190 assigns to the fault log data 180c the fault identifier detected in step S505, a time identifier indicating the time contained in the log data 180b at which the occurrence of the fault was detected, and a period identifier indicating the entire period of the combined log data.

For example, if the log data 180b is information for one minute, the failure log data 180c may include information for five minutes. In other words, it may include five pieces of log data 180b that are consecutive in time. More specifically, the failure log data 180c may include five pieces of log data 180b, consisting of two pieces of log data 180b corresponding to two minutes before the failure occurs, one piece of log data 180b corresponding to one minute at the time the failure occurs, and two pieces of log data 180b corresponding to two minutes after the failure occurs.

The fault log data 180c is not limited to a period of five minutes as in the above example, but may be set by the operator via the operation unit 150 and the control unit 190 may generate the fault log data 180c based on the log data 180b for the period corresponding to this setting.

Next, the fault log transmission process by the pump device 100 will be described with reference to FIG. 6. FIG. 6 is a flowchart explaining the fault log transmission process, which is performed by the control unit 190. Specifically, the process is performed when a preset time or time interval arrives, when a fault is detected (when new fault log data 180c is generated), etc.

First, in step S601, the control unit 190 reads out the fault log data 180c stored in the memory unit 180, controls the short-distance communication unit 140 to transmit the read fault log data 180c to the external device 300, and proceeds to step S602. Note that when transmitting to the pump management device 200, the long-distance communication unit 130 is used.

In step S602, the control unit 190 determines whether the transmission in step S601 was successful. For example, the control unit 190 determines that the transmission was successful when it receives an acknowledgement indicating receipt from the external device 300. If the transmission was successful, the control unit 190 proceeds to step S603. If the transmission was not successful, the control unit 190 proceeds to step S604.

In step S603, the control unit 190 erases the successfully transmitted error log data 180c from the memory unit 180 and ends the process.

In step S604, the control unit 190 adds 1 to increment the retransmission count value m, and then proceeds to step S605.

In step S605, the control unit 190 determines whether the retransmission count value m has exceeded the upper threshold value M. If the retransmission count value m has exceeded the upper threshold value M, the control unit 190 gives up on retransmission and ends the process. If the retransmission count value m has not exceeded the upper threshold value M, the control unit 190 proceeds to step S601 and attempts retransmission.

Next, the diagnostic log transmission process performed by the pump device 100 will be described with reference to FIG. 7. FIG. 7 is a flowchart illustrating the diagnostic log transmission process, which is performed by the control unit 190.

In the following explanation, the diagnostic log transmission process is described as being initiated when the pump device 100 is powered on and operation begins, but it may also be initiated as appropriate in response to instructions from an operator at any time.

In step S701, the control unit 190 determines whether a predetermined timing has arrived, and if the timing has arrived, the process proceeds to step S702. On the other hand, if the timing has not arrived, the process proceeds to step S701 again to monitor the arrival of the timing.

Specific examples of the specified timing include when a preset time or time interval arrives, when the flow sensor 174 detects a low water volume and stops the pump unit 100P, or when the pump unit 100P is operated for the first time that day.

In step S702, the control unit 190 reads the log data 180b (the latest one or all the log data 180b) stored in the memory unit 180, controls the short-range communication unit 140 to transmit the read log data 180b to the external device 300 as diagnostic log data, and proceeds to step S701. When transmitting to the pump management device 200, the long-range communication unit 130 is used.

Next, the diagnostic process by the pump management device 200 or the external device 300 will be described with reference to FIG. 8. FIG. 8 is a flowchart for explaining the diagnostic process, which is performed by the control unit 260 of the pump management device 200 or the control unit 370 of the external device 300. In the following explanation, the diagnostic process by the external device 300 will be explained, but since the process by the pump management device 200 is similar, an explanation of the pump management device 200 will be omitted.

First, in step S801, the control unit 370 controls the short-range communication unit 340 to receive diagnostic log data transmitted from the pump device 100, and then proceeds to step S802. Note that the log data received here is the log data 180b transmitted in step S702.

In step S802, the control unit 370 stores the log data received in step S801 in the memory unit 360 as diagnostic log data 360b, and then proceeds to step S803.

In step S803, the control unit 370 analyzes the log data 360b saved in step S802 based on the diagnostic table 360a, and proceeds to step S804. Specifically, the control unit 370 analyzes the detection results of various sensors, the operational settings of the pump device 100, and the operator's operation (such as the operator's setting of the select switch) contained in the log data 360b based on the diagnostic table 360a.

In step S804, the control unit 370 determines whether or not an abnormality has occurred based on the analysis results of step S803. If an abnormality has occurred, such as the sensor detection result indicating an abnormal value, the process proceeds to step S805. On the other hand, if no abnormality has occurred, the process proceeds to step S806.

In step S805, the control unit 370 executes anomaly response processing and proceeds to step S806. The specific content of the anomaly response processing will be described later with reference to FIG. 9.

In step S806, the control unit 370 determines whether or not the worker continues to perform an erroneous operation based on the analysis result of step S803. If the worker continues to perform an erroneous operation, the process proceeds to step S807. If the worker does not continue to perform an erroneous operation, the process proceeds to step S808. The determination of an erroneous operation is made based on, for example, standard operation information indicating a standard operation that has been prepared in advance. The standard operation information is stored in the storage unit 360.

In step S807, the control unit 370 executes an operation error response process, and the process proceeds to step S808. The specific contents of the operation error response process will be described later with reference to FIG. 10.

In step S808, the control unit 370 determines whether the operator has left the incorrect settings in place based on the analysis results of step S803. The determination of incorrect settings is made, for example, based on standard setting information indicating standard settings prepared in advance or settings used when normal operation was performed in the past. The standard setting information is stored in the storage unit 360.

If the incorrect settings remain, the process proceeds to step S809; if the incorrect settings do not remain, the process ends.

In step S809, the control unit 370 executes the erroneous setting response process and ends the process. The specific contents of the erroneous setting response process will be described later with reference to FIG. 11.

Next, referring to FIG. 9, the abnormality response processing by the pump management device 200 or the external device 300 will be described. FIG. 9 is a flowchart for explaining the abnormality response processing, which is performed by the control unit 260 of the pump management device 200 or the control unit 370 of the external device 300. In the following explanation, the abnormality response processing by the external device 300 will be explained, but since the processing by the pump management device 200 is similar, an explanation of the pump management device 200 will be omitted.

First, in step S901, the control unit 370 determines whether the setting value of the pump device 100 indicated in the diagnostic log data 360b is within the allowable range based on the diagnostic table 240a. If the setting value is within the allowable range, the process proceeds to step S903. If the setting value is not within the allowable range, the process proceeds to step S902.

In step S902, the control unit 370 controls the display unit 320 to notify the operator of the abnormal settings by displaying a message indicating that an abnormal setting has been set, and then the process proceeds to step S908.

Here, the set value may be modified by remote control to a value within or close to the allowable range. Specifically, the set value of the pump device 100 is changed to within the allowable range indicated in the diagnostic table 360a by remote control of the pump device 100 via the short-range communication unit 340.

In step S903, the control unit 370 detects past log data 360b for the pump device 100 from the memory unit 360, and proceeds to step S904. The past log data 360b detected here includes information when the pump device 100 was operating normally (or information when the frequency of failures was low).

In step S904, the control unit 370 compares the setting values of the pump device 100 indicated in the diagnostic log data 360b with the setting values indicated in the past log data 360b detected in step S903 to detect any changed settings. If any changed setting values are present, the process proceeds to step S906. On the other hand, if no changed setting values are present, the process proceeds to step S905.

In step S905, the control unit 370 controls the display unit 320 to notify the operator of the occurrence of an abnormality by displaying a message indicating that an abnormality has occurred, and requests an inspection, and then proceeds to step S908.

In step S906, the control unit 370 remotely controls the pump device 100 via the short-range communication unit 340 to set the setting value indicated by the past log data 360b detected in step S903 in the pump device 100, and the process proceeds to step S907. That is, the control unit 370 remotely controls the pump device 100 to correct the setting value, returning it to the setting value when normal operation was performed in the past, and restarts (resets) the pump device 100.

The content of the correction made here is not limited to the above. For example, it may be changed to the value closest to the current erroneous setting within the allowable range. Specifically, if the allowable range is shown as "10 to 50" in diagnostic table 360a, the setting value in past log data 360b is "20," and the erroneous setting value is "60," the corrected setting value is set to "50," the value closest to the allowable range (in the above example, "20" would be set).

In step S907, the control unit 370 controls the display unit 320 to display to the worker that an abnormality has occurred and that the setting value has been changed to the setting value described above, thereby notifying the worker of the occurrence of the abnormality and requesting inspection, and proceeds to step S908. Note that here, specifically, the changed setting value and the setting value before the change may be displayed together so that the worker can compare them.

In step S908, the control unit 370 determines whether or not there is any degradation of the part based on the results of the analysis in step S803. If there is any degradation of the part, the process proceeds to step S909, whereas if there is no degradation of the part, the process ends.

In step S909, the control unit 370 controls the display unit 320 to display to the worker that a part needs to be replaced, and controls the long-distance communication unit 330 to send an email to the email address of a pre-set administrator (or the owner of the pump device 100) notifying the worker that a part needs to be replaced, and then ends the process.

Next, the operation error response processing by the pump management device 200 or the external device 300 will be described with reference to FIG. 10. FIG. 10 is a flowchart for explaining the operation error response processing, which is performed by the control unit 260 of the pump management device 200 or the control unit 370 of the external device 300. In the following explanation, the operation error response processing by the external device 300 will be explained, but since the processing by the pump management device 200 is similar, a description of the pump management device 200 will be omitted.

First, in step S1001, the control unit 370 refers to the diagnosis table 240a and determines whether the pump device 100 being diagnosed is a pump device for which settings have been made based on special circumstances. Here, a pump device for which settings have been made based on special circumstances means a pump device for which non-standard settings have been made due to special circumstances.

If the pump device is one for which settings have been made based on special circumstances, the process proceeds to step S1002. On the other hand, if the pump device is not one for which settings have been made based on special circumstances, the process proceeds to step S1003.

In step S1002, the control unit 370 controls the display unit 320 to display a message indicating that an operation that would be considered an incorrect operation under normal operation has been performed on a pump for which settings have been made based on special circumstances, thereby alerting the operator and terminating the process.

Note that the operation determined to be an erroneous operation may be corrected by remote control. Specifically, a different operation is instructed to the pump device 100 by remote control via the short-range communication unit 340, and this instruction is given priority by the control unit 190 over the operation by the operator. For example, the control unit 190 of the pump device 100 accepts instructions from the external device 300 with priority over operation by the hard switch of the select switch.

In step S1003, the control unit 370 controls the display unit 320 to display a message to the operator indicating that an operation error has occurred, thereby warning the operator of the operation error and requesting confirmation, and then proceeds to step S1004.

In step S1004, the control unit 370 refers to the diagnostic table 360a to determine whether remote operation is permitted for the pump device 100 being diagnosed. If permitted, the control unit 370 proceeds to step S1005. If not permitted, the control unit 370 ends the process.

In step S1005, the control unit 370 determines whether a certain period of time has elapsed since the erroneous operation was notified in step S1003. This is the grace period before remote operation is performed, and within this grace period the worker can take some kind of action.

If a certain period of time has elapsed, the process proceeds to step S1006. If an operation has been performed by an operator, the process proceeds to step S806, where the operation performed by the operator may be confirmed.

In step S1006, the control unit 370 instructs the pump device 100 to operate by remotely controlling the pump device 100 via the short-range communication unit 340, and the process proceeds to step S1007. Note that the above instructions given by remote control are given priority by the control unit 190 over operations by an operator. For example, the control unit 190 of the pump device 100 accepts instructions from the external device 300 with priority over operations using the hard switch of the select switch.

In step S1007, the control unit 370 controls the display unit 320 to display a message to the worker indicating that the worker's operation has been canceled by remote operation and that another operation has been performed, thereby notifying the worker of the remote operation, requesting confirmation of the operation, and terminating the process. Note that here, specifically, the canceled operation and the content of the remote operation may be displayed together so that the worker can recognize them.

Next, the erroneous setting response process by the pump management device 200 or the external device 300 will be described with reference to FIG. 11. FIG. 11 is a flowchart for explaining the erroneous setting response process, which is performed by the control unit 260 of the pump management device 200 or the control unit 370 of the external device 300.

The following description will explain the erroneous setting response processing by the external device 300, but as the processing by the pump management device 200 is similar, a description of the pump management device 200 will be omitted.

First, in step S1101, the control unit 370 refers to the diagnosis table 240a and determines whether the pump device 100 being diagnosed is a pump device for which settings have been made based on special circumstances. Here, a pump device for which settings have been made based on special circumstances means a pump device for which non-standard settings have been made due to special circumstances.

If the pump device is one for which settings have been made based on special circumstances, the process proceeds to step S1102. On the other hand, if the pump device is not one for which settings have been made based on special circumstances, the process proceeds to step S1103.

In step S1102, the control unit 370 controls the display unit 320 to display a warning to the operator that the pump, for which settings have been configured based on special circumstances, has settings that would be determined to be incorrect under normal operation, and then ends the process.

Note that the settings determined to be erroneous may be corrected by remote control. Specifically, a different operation may be instructed to the pump device 100 by remote control via the short-range communication unit 340, and this instruction may be given priority by the control unit 190 over the operation by the operator.

For example, if an operator mistakenly sets a value to "60" when the acceptable range is "10 to 50," the control unit 370 will remotely set the acceptable range value to "50," which is closest to the incorrectly set value of "60."

The value to be corrected by the remote control is determined, for example, as follows. That is, the memory unit 360 pre-stores information on the acceptable range, or reads it from the control table 180a of the pump device 100, and determines the correction value "50" based on this information (acceptable range "10 to 50") and the value set by the operator ("60" in the above example).

In step S1103, the control unit 370 controls the display unit 320 to display a message to the operator indicating that an incorrect setting has been made, thereby warning the operator of the incorrect setting and requesting confirmation, and then proceeds to step S1104.

In step S1104, the control unit 370 refers to the diagnostic table 360a to determine whether remote operation is permitted for the pump device 100 being diagnosed. If permitted, the control unit 370 proceeds to step S1105. If not permitted, the control unit 370 ends the process.

In step S1105, the control unit 370 determines whether a certain amount of time has passed since the incorrect setting was notified in step S1103. This is the grace period before remote operation is performed, and within this grace period, the worker can take some kind of action.

If a certain period of time has elapsed, the process proceeds to step S1106. If the settings have been modified by an operator, the process may proceed to step S808 to confirm the modified settings.

In step S1106, the control unit 370 analyzes and finds optimal setting values, and proceeds to step S1107. Specifically, the control unit 370 references the past log data 360b of the pump device 100 being diagnosed, or the past log data 360b of another pump device 100 of the same model installed in a similar environment, and finds the setting values when the pump device 100 was operating normally.

In step S1107, the control unit 370 remotely controls the pump device 100 via the short-range communication unit 340 to instruct the pump device 100 to modify the settings to the settings determined by the analysis in step S1106, and the process proceeds to step S1108. For example, the control unit 370 instructs the pump device 100 to overwrite the existing setting value with a value according to the instruction from the external device 300, and the control unit 190 modifies the settings accordingly.

In step S1108, the control unit 370 controls the display unit 320 to display a message to the worker indicating that the settings have been modified by remote operation, thereby notifying the worker of the remote operation, and asks the worker to confirm the setting modification, and then ends the process. Note that, specifically, the settings before modification and the modified settings may be displayed together so that the worker can recognize them.

As described above, in this embodiment, the pump devices 100-1 to 100-n each detect information related to the operation of the pump section 100P (detection values of various sensors, set values, operator operations, etc.), associate this information with information indicating the time, generate log data 180b, store it in the memory section 180, and transmit this log data 180b to the pump management device 200 and external device 300.

Therefore, according to this embodiment, the status of the pump devices 100-1 to 100-n can be understood from the log data 180b, allowing accurate diagnosis.

In addition, in the above embodiment, the pump management device 200 and the external device 300 detect abnormalities, operational errors, and incorrect settings based on the log data 180b received from the pump devices 100-1 to 100-n, and deal with them remotely. Therefore, even if an operator cannot immediately go to the site, immediate action can be taken, which can help with, for example, personnel shortages.

The pump management device 200 and external device 300 also determine the deterioration of parts, and if any deterioration is detected, notify the worker or manager that the part needs to be replaced. This allows the worker to immediately begin the task of ordering the part, or the parts can be ordered automatically. The manager can recognize the need for part replacement at an early stage, which is useful for understanding expenses and managing the budget.

In addition, in the above embodiment, the pump device 100 performs self-diagnosis to detect the occurrence of a fault, and when a fault occurs, the log data at that time and the log data before and after the fault are stored as fault log data 180c. Therefore, the cause of the fault can be identified based on the fault log data 180c.

Failure log data 180c is also transmitted to the pump management device 200 and the external device 300. If the transmission is successful, it can be erased from the pump device 100. This makes it possible to conserve the limited storage area of the storage unit 180.

Furthermore, since the fault log data 180c includes an identifier indicating the type, content, and time of the fault that occurred, the pump management device 200 or external device 300 that receives the fault log data 180c can grasp in detail the type, content, and time of the fault that occurred.

By the way, it is desirable for the selector switch (hardware switch) that switches the operation of the pump device 100 between "stop" and "standby" to always be set to "standby" during normal use, and it is often set to "stop" only when a forced stop is required for maintenance or factory equipment reasons.

For this reason, unless the site is special, the above procedure may be sufficient, but there are cases where the user forgets to reset the select switch after maintenance, or forgets to set it appropriately during daily operation of factory equipment.

In contrast, in this embodiment, in a site where there are no special circumstances, if an erroneous operation (including forgetting to operate) is detected, an alert is issued, and after a certain period of time has passed, the operation is changed by remote control. This makes it possible to correct the erroneous operation.

Furthermore, according to this embodiment, erroneous setting of the setting value can be found.
There are cases where the pressure generated by the pump device must not exceed a certain pressure, such as when the piping system at the site where the pump device 100 is installed is aging, or when other equipment connected to the secondary side of the pump device is aging.

Conventionally, since there is no way to manage this automatically, the set value is managed by posting a note on the pump device 100 or contacting the person in charge, but due to a shortage of personnel, etc., there is a possibility that information transmission is inadequate or the person in charge makes a mistake, resulting in the pressure being set above the settable pressure.

In such cases, the allowable pressure of the equipment may be exceeded, causing leaks from the piping system, or a valve installed in the piping system may release pressure and trigger an alarm when the pressure in the piping exceeds a certain value, which may cause equipment other than the pump to be shut down. Since the settable pressure differs from site to site, individual management is required, but this tends to make manual management cumbersome.

In this embodiment, the pump management device 200 and the external device 300 are provided with diagnostic tables 240a and 360a, and the allowable setting ranges for each of the various setting values can be set in these tables for each of the pump devices 100-1 to 100-n.

Then, log data 180b is obtained from the pump device 100, and if a setting is made that exceeds the allowable setting range in the table, the setting is returned to the value before the setting change based on the past log, or the incorrect setting is changed to the closest value within the allowable setting range.

In addition, if a setting value is changed, since it is assumed that there is an on-site worker who changed the setting, the system notifies the user that an abnormal value has been set and prompts the user to make a correction, or displays the corrected setting value on the external device 300. The allowable setting range can also be set directly on the pump device 100, but this is difficult for personnel with little knowledge to operate, so correction support using the external device 300 or the like is effective.

Furthermore, according to this embodiment, it is possible to optimize the set values that are not suited to the actual site.
For example, in the case of a direct-connection pressurizing type pump device that is directly connected to a water pipe, the primary pressure (suction pressure) of the pump device varies from site to site due to various factors such as the pressure of the water main at the site, and the diameter, length, and linearity of the pipe that branches off from the water main and is connected to the pump.

The set value that controls the pressure response of the pump device 100 is not a site-specific setting, but may be a uniform shipping value. This is because there is no need to change it from the shipping value at many sites. However, if the suction pressure is low and the piping branching off from the main pipe is long and has many bends, the suction side pressure will be low at startup, which may have a negative impact on surrounding pump devices. As a result, the water used by the user (water coming out of the faucet) will pulsate, which may affect convenience. One way to deal with this is to change the set value that controls the pressure response. In other words, this is addressed by making the pressure control gentler at startup, etc. This response is generally done by an expert who changes the setting only after symptoms occur, and adjustments are made for each site.

In contrast, in the above embodiment, the pump management device 200 or the external device 300 acquires the log data 180b, and based on this data, the pump management device 200 or the external device 300 can remotely change the appropriate value. Specifically, based on the log data 180b, it is detected that the suction pressure falls below the standard when the pump device 100 is started, and the set value is remotely changed to make the start-up gentler. Thereafter, while the pump device 100 is operating, the secondary pressure (discharge pressure) of the pump device 100 is monitored from the subsequent log data 180b, and if it rises or falls above the standard, the set value is changed remotely to keep the rise or fall within the standard and to make the pressure response gentler.

Furthermore, according to this embodiment, setting changes that are not suited to the actual situation can be corrected.
As described above, since the shipping value is uniform, the setting value may not necessarily be optimized for each site. For example, during a test run after the installation of the pump device 100, if the user feels that the start-up is slow and wants to start up faster than the shipping setting value (manufacturer's recommended value), the user may change the setting so that the time it takes for the motor to reach a specified number of rotations at start-up is faster than usual.

Although these settings changes are customizations for each user, they must be made with care. Specifically, even if the changed setting value is within the range that will not cause problems in many sites, there may be cases where the setting should not be changed due to site-specific issues. For example, even if the value changed through customization is within the manufacturer's allowable change range, if the change is not suitable for the site, there is a possibility of an abnormality such as an overcurrent. Situations like this are difficult for users to judge, and even knowledgeable people will find it difficult to clarify without spending time checking.

In contrast, in the above embodiment, for example, when an overcurrent occurs, the external device 300 (or the pump management device 200) detects a change in settings based on the log data 360b from when normal operation was being performed (or when failures occurred less frequently) to identify the cause of the malfunction, and remotely restores the changed settings to those during normal operation, thereby eliminating the malfunction.

In addition, in the above remote operation, the allowable setting range of the changed setting value may be changed to a value narrower than the allowable range recommended by the manufacturer and registered. This allows the user to understand that the change is not appropriate from the next time.

In some of the examples described above, log data of a small data size and a relatively short period (e.g., about one minute) is frequently sent to the pump management device 200 and the external device 300, but this is not limited to this. Depending on the site, it can also be used to send log data of a large data size and for a long period of time.

For example, in cases where there is a symptom that is not a malfunction, such as poor water flow, or where the device is operating irregularly at irregular intervals, there may be no trigger for log acquisition, and it may be necessary to acquire logs over a long period of time to identify the cause. Even in such cases, long-term log data can be sent and received between the pump device 100 and the external device 300 via short-range communication, which does not incur communication fees.

When the external device 300 is used to collect log data over a long period of time, a power supply is required. In this embodiment, however, power can be supplied from a mobile battery 112 mounted on the pump device 100. Also, because it is a battery, logs can be continuously acquired even in the event of a power outage.

In addition, in the above embodiment, an expensive high-precision sensor (e.g., CT), which cannot be installed due to cost issues, can be connected to the communication connector 160 in the pump device 100 to be shipped, and log data 180b can be generated. Therefore, information acquired by the shipping test device at the manufacturer at the time of shipment is stored in advance in the external device 300 (or pump management device 200), and this information can be compared with the log data 180b including the detection results of the high-precision sensor to perform a more accurate diagnosis.

For example, data can be obtained from a high-precision sensor for the pump device 100 to be shipped, and this data can be compared with data based on a log obtained later. For example, the log data 180b can include inverter information including the rotation speed and the pressure detected by the pressure sensor 172. From the relationship between the pressure and the rotation speed, the control unit 260 can estimate the current value, and compare this estimated current value with the current value detected by the high-precision sensor (CT) obtained at the time of shipment. Similarly, from the relationship between the rotation speed and pressure, the control unit 260 can estimate the flow rate.

Note that this 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, components described in different embodiments may be appropriately combined.

For example, the pump management device 200 and the external device 300 may compare the log data 180b before and after the occurrence of an abnormality with the log data 180b of the other pump devices 100-1 to 100-n to review the threshold value that is the criterion for determining the occurrence of an abnormality. In this way, if the threshold value for determining the occurrence of an abnormality is not set sufficiently, updating the threshold value may improve the accuracy of the threshold value that previously determined the occurrence of an abnormality by determining the occurrence of an abnormality with a safety margin.
In the above embodiment, the optimal settings are periodically analyzed and the settings are changed as described in step S1106. However, the analysis of the optimal settings is not limited to being performed periodically, and may be performed when other conditions are satisfied.

Generally, among the settings of the pump device 100, there are quite a few parameters that are set uniformly, and in many cases there is no need to change them when starting up after installation, so the device can be operated with those values unchanged. However, the pump device 100 may deteriorate over time, and the equipment around the pump device 100 may also deteriorate, and the environment in which the pump device 100 is set may also change. As a result, there are cases in which it is better to change the settings.

For this reason, the pump device 100 may continue to log the current peak value from the initial installation time and transmit the log to the pump management device 200 and the external device 300, and the pump management device 200 and the external device 300 may analyze the optimal settings when the respective control units become larger (or smaller) than at the initial time, exceeding a threshold value.

In this case, the optimal setting is to determine the allowable range of the current peak value in advance, and if there is a margin for the upper limit within the allowable range at the beginning of operation, the acceleration time is set to increase. On the other hand, if there is no margin, for example, no changes are made to the factory settings, or, in adverse conditions, the acceleration time is set to decrease. Note that even if such changes are made, the changes are notified as described in step S1108.

The intermediate DC voltage of the inverter of the pump device 100 may also be optimized. Generally, the voltage increases when the pump is stopped, but if it is higher than the allowable range, the deceleration time is extended to stop the pump gradually, thereby controlling the voltage increase to be small. Such optimal settings may be performed by the pump management device 200 or the external device 300.

It goes without saying that various modifications can be made without departing from the spirit of this invention.
