Description

[Technical field]

[0001] An embodiment of the present invention relates to a pump device for supplying liquid. [Background technology]

[0002] In recent years, pump equipment maintenance has faced an aging workforce and a shortage of successors, creating a demand for remote equipment monitoring. This has led to the development of pump equipment equipped with communication units (or communication modules) that use mobile phone networks, etc.

[0003] Pump equipment maintenance may require partial replacement, such as the communication unit, but due to the aforementioned background, it is not easy for maintenance personnel to deepen their knowledge of communication in addition to mechanical maintenance.

[0004] [Patent Document 1] Patent No. 4586133 Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a pump device capable of reducing the maintenance burden associated with communications. [Means for solving the problem]

[0006] A pump device according to an embodiment includes a communication unit, a unit interface, a second storage unit, and a communication setting unit. The communication unit includes a first storage unit and performs wireless communication based on communication setting information stored in the first storage unit. The unit interface is connectable to a communication unit, and the second storage unit stores the communication setting information stored in the first storage unit. When a communication unit connected to the unit interface is replaced, the communication setting unit outputs the communication setting information stored in the second storage unit to the communication unit connected to the unit interface and stores the communication setting information in the first storage unit included in the communication unit. The second storage unit stores the communication setting information and the subscriber identification information stored in the first storage unit. The communication setting unit determines that the communication unit connected to the unit interface has been replaced when the subscriber identification information stored in a SIM (Subscriber Identity Module) mounted on the communication unit differs from the subscriber identification information stored in the second storage unit. Effect of the Invention

[0007] According to the present invention, it is possible to provide a pump device capable of reducing the maintenance burden relating to communication. [Brief description of the drawings]

[Diagram 5] 4 is a flowchart illustrating a communication setting process for the pump device shown in FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pump device according to an embodiment will be described below with reference to the drawings. 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. In this pump management system, a pump management device 200 manages pump devices 100-1 to 100-n via a mobile communication network NW.

[0010] 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 water supplied from a main water pipe using a pump driven by the power of a motor. Note that the pump device may be intended for liquids other than purified water.

[0011] In addition, there are various types of pumps suitable for the pump devices 100-1 to 100-n depending on the 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.

[0012] 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.

[0013] 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.

[0014] The pump management device 200 monitors and manages the operational status of the pump devices 100-1 to 100-n, and collects and records information on the operational status of the pump devices 100-1 to 100-n via a gateway device GW and a mobile communication network NW, as well as performing remote control.

[0015] 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.

[0016] 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.

[0017] The pump unit 100P may have various configurations, but since it may be a pump of any type, whether general or special, a detailed description will be omitted. The pump unit 100P is not limited to the configuration described above.

[0018] 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 memory unit 160, a communication connector 170, a sensor interface (I / F) 180, and a control unit 190.

[0019] 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.

[0020] 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.

[0021] The display unit 120 is a display device using a device such as a liquid crystal panel, an organic EL (Electro Luminescence) panel, a 7-segment LED, or an LED lamp, and visually displays information provided from the control unit 190 to an operator.

[0022] The information displayed on the display unit 120 under the control of the control unit 190 includes information (including communication attributes) 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.

[0023] 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.

[0024] In addition, the long-distance communication unit 130 has a mechanism and interface that can be attached and detached to an interface 131 (an example of a unit interface) 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.

[0025] The long distance communication unit 130 is equipped with a Subscriber Identity Module (SIM) as subscriber identification information for using a communication service provided by a communication carrier, and performs communication using the subscriber identification information.

[0026] The SIM may be a SIM card or an eSIM (Embedded SIM). In the case of a SIM card, the communication unit is provided with a card slot as an interface, and is configured to be removable (replaceable).

[0027] 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.

[0028] The short-range 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 support these communication standards.

[0029] 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.

[0030] The operation unit 150 is a touch panel or a plurality of key switches provided on the display of the display unit 120, and receives requests and instructions from the operator and transmits them to the control unit 190. Note that, in addition to such physical input means, a microphone may be provided so that the control unit 190 recognizes commands indicated by input voice and receives the requests and instructions from the operator.

[0031] The storage unit 160 uses a semiconductor memory such as a Synchronous Dynamic RAM (SDRAM), a NAND flash memory, or an Erasable Programmable ROM (EPROM), and is an example of a second storage unit.

[0032] The memory unit 160 stores the control program and control data of the control unit 190, the operation log of the pump device 100, the detection results of various sensors, the types of communication attributes set in the pump device 100, schedule information for various operations (e.g., the timing (time) of periodic notifications), backup information for communication settings, and the like.

[0033] The communication connector 170 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.

[0034] The sensor interface 180 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 detected by the various sensors to the control unit 190.

[0035] In FIG. 2, a water leak sensor 181, a pressure sensor 182, a flood sensor 183, and a flow rate sensor 184 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 180.

[0036] The water leakage sensor 181 detects water leakage from around the pump unit 100P. The pressure sensor 182 detects the pressure of the liquid pumped by the pump section 100P. The flood sensor 183 detects that flooding has occurred around the pump device 100 due to flooding or the like. Flow sensor 184 detects the amount of liquid being pumped by pump portion 100P.

[0037] The control unit 190, which controls each unit of the control panel 100C, includes a processor and a memory. The memory stores the control program and control data read from the storage unit 160, and the processor executes the control program and performs various controls and processes according to the control data.

[0038] 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, communication information backup processing, and communication setting processing. In other words, the control unit 190 is an example of a communication setting unit and a memory control unit.

[0039] 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.

[0040] The communication information backup process is a process in which, when instructed by an operator or when communication is performed normally, information necessary for communication is read from the long-distance communication unit 130 and saved (backed up) in the memory unit 160.

[0041] The communication setting process is executed, for example, when an operator gives instructions, when long-distance wireless communication cannot be performed normally, or when a communication unit equipped with long-distance communication unit 130 is replaced (or has been replaced), and is a process for resetting, in long-distance communication unit 130, information necessary for communication that has been saved in advance by the above-mentioned communication information backup process or the like.

[0042] 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.

[0043] 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.

[0044] Next, a more detailed description will be given of the configurations of the long-distance communication unit 130, the storage unit 160, and the control unit 190. Fig. 3 shows a part of these configurations in more detail, and the following description will be given with reference to this figure.

[0045] As described above, the long-distance communication unit 130 is a communication unit that is detachably connected to the interface 131 that is connected to the control unit 190, and is capable of exchanging control signals and data with the control unit 190 via the interface, and includes at least a communication unit control unit 1310, a memory unit 1320, a SIM card 1330, a card interface 1331, and a wireless communication unit 1340.

[0046] The communication unit control section 1310, which controls each section of the long-distance communication section 130, includes a processor and a memory. The memory stores control programs and control data read from the storage section 1320, and the processor executes the control programs and performs various controls and processes according to the control data.

[0047] Specific control and processing by the communication unit control unit 1310 includes controlling the wireless communication unit 1340 based on information stored in the memory unit 1320 to realize long-distance wireless communication, or outputting information stored in the memory unit 1320 or SIM card 1330 to the control unit 190 in accordance with instructions (requests) from the control unit 190.

[0048] The storage unit 1320 uses semiconductor memory such as SDRAM, NAND flash memory, or EPROM, and stores the control program and control data of the communication unit control unit 1310, as well as having a directory in which information can be rewritten by the communication unit control unit 1310.

[0049] In addition, the memory unit 1320 is an example of a first memory unit, and stores, in the rewritable directory, SIM information 1321 read by the communication unit control unit 1310 from the SIM card 1330, and communication setting information 1322 including setting information and setting parameters necessary for communication by the wireless communication unit 1340.

[0050] The setting information and setting parameters include, for example, a frequency band used for long-distance wireless communication, information for identifying a communication service provider used in the long-distance wireless communication, an APN (Access point Name) setting of the communication service provider, a management number of the pump device 100, etc. The management number is information that allows the pump management device 200 to identify the pump device 100.

[0051] The SIM card 1330 is a card-type storage medium that stores subscriber identification information for using communication services provided by a communication carrier, and is electrically connected to a card interface 1331 so that the information can be read by the communication unit control unit 1310.

[0052] When the SIM card 1330 is connected to the card interface 1331, the stored subscriber identification information is read by the communication unit control unit 1310, and the read subscriber identification information is recorded in the memory unit 1320 as SIM information 1321.

[0053] Therefore, for example, when the SIM card 1330 connected to the card interface 1331 is replaced, the subscriber information stored in the newly connected SIM card 1330 is read, and the SIM information 1321 in the memory unit 1320 is recorded (updated) to this read subscriber identification information.

[0054] The wireless communication unit 1340 is a wireless communication module that complies with communication standards such as LTE, 4G, or 5G, and is controlled by the communication unit control unit 1310. It communicates wirelessly with the base station BS and communicates with the pump management device 200, for example, through a mobile communication network NW and a gateway device GW.

[0055] As described above, memory unit 160 stores various information such as the control program and control data of control unit 190, and also stores SIM information 1321 and communication setting information 1322 obtained by control unit 190 from long-distance communication unit 130 as SIM information 1601 and communication setting information 1602, i.e., backup information, respectively.

[0056] Next, a description will be given of the operation of the pump device 100 having the above configuration. In the following description, the communication information backup process and the communication setting 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.

[0057] First, the communication information backup process by the pump device 100 will be described with reference to Fig. 4. This communication information backup process is performed by the control unit 190. Fig. 4 is a flowchart of the communication information backup process.

[0058] This communication information backup process is started by the control unit 190 when it detects either a case where an instruction is received from an operator via the operation unit 150, or where long-distance wireless communication is set up (including a change in the setting) and long-distance wireless communication is performed normally.

[0059] In step S401, control unit 190 requests long-distance communication unit 130 to output information related to long-distance wireless communication, and proceeds to step S402. Communication unit control unit 1310 that has received the request reads SIM information 1321 and communication setting information 1322 from storage unit 1320, which have been read from SIM card 1330 and recorded in storage unit 1320 in order to perform long-distance wireless communication, and outputs these to control unit 190.

[0060] In step S402, the control unit 190 acquires the SIM information 1321 and the communication setting information 1322 output from the long-distance communication unit 130, and records them in the storage unit 160 as the SIM information 1801 and the communication setting information 1802, i.e., as backup information, and ends the process.

[0061] Next, a communication setting process performed by the pump device 100 will be described with reference to Fig. 5. This communication setting process is performed by the control unit 190. Fig. 5 is a flowchart of the communication setting process.

[0062] This communication setting process is started by the control unit 190 when it detects any of the following cases: when an operator gives instructions via the operation unit 150, when long-distance wireless communication cannot be performed normally, or when a communication unit equipped with the long-distance communication unit 130 or the SIM card 1330 has been replaced.

[0063] In step S501, control unit 190 requests long-distance communication unit 130 to output information related to communication. In response to this, in long-distance communication unit 130, the request is accepted by communication unit control unit 1310, which reads out SIM information 1321 and communication setting information 1322 recorded in storage unit 1320 and outputs them to control unit 190. When control unit 190 acquires this information (SIM information 1321 and communication setting information 1322), the process proceeds to step S502.

[0064] In step S502, control unit 190 reads out SIM information 1601 stored in storage unit 160, compares it with SIM information 1321 acquired in step S501, and determines whether the two match. That is, in step S502, it determines whether the same SIM card is being used (whether the SIM card has not been changed).

[0065] If there is a match, the process proceeds to step S503; if there is no match, it is determined that the SIM card has been replaced or that the long-distance communication unit 130 connected to the interface 131 has been replaced, and the process proceeds to step S504.

[0066] In step S503, the control unit 190 controls the display unit 120 to display OK, which indicates that the SIM cards match, and proceeds to step S506. In this way, the worker who sees the OK display recognizes that the control panel 100C has detected that the SIM card has not been changed, and that communication settings can be made using the backup information.

[0067] In step S504, the control unit 190 controls the display unit 120 to display NG, indicating that the SIM cards do not match, and also displays a message asking the worker whether it is OK to set the backup information in the long-distance communication unit 130, and then proceeds to step S505.

[0068] As a result, the worker who sees the NG display realizes that the control panel 100C has detected that the SIM card has been changed and that there is a possibility that the backup information will not be able to set up communications. At this point, the worker considers setting up backup information.

[0069] For example, even if the SIM card has been changed, if it is a SIM card from the same telecommunications carrier, communication may be possible by setting backup information, so this can be left to the discretion of the worker.

[0070] In step S505, the control unit 190 receives an instruction from the operator via the operation unit 150. If an instruction to set backup information is received, the process proceeds to step S506. On the other hand, if an instruction to set new information is received, the process proceeds to step S509.

[0071] In step S506, control unit 190 determines whether long-distance communication unit 130 is in communication. If communication is in progress, control proceeds to step S507, whereas if communication is not in progress, control proceeds to step S508.

[0072] In step S507, the control unit 190 controls the display unit 120 to display an error message indicating that communication is in progress, and ends the process. As a result, a worker who sees the error message will, for example, consider that communication is in progress and reconsider the need for communication setting work, etc.

[0073] In step S508, control unit 190 reads out communication setting information 1602 from the backup information stored in storage unit 160, outputs this to long-distance communication unit 130, requests an update, and proceeds to step S511.

[0074] In response to this, in the long distance communication section 130 , the above request is accepted by the communication unit control section 1310 , and communication setting information 1602 acquired in response to the above request is recorded in the storage section 1320 as communication setting information 1322 .

[0075] In step S509, the control unit 190 accepts manual input of setting information and setting parameters from the worker, and the process proceeds to step S510. Specifically, the worker performs the input through the operation unit 150. The information to be input here may be preset in the storage unit 160 in advance, and the input may be completed simply by the worker selecting the information.

[0076] Alternatively, an operator operates a smartphone or a tablet terminal to transmit data such as setting information and setting parameters via short-range wireless communication. The transmitted data is received by the short-range communication unit 140.

[0077] In step S510, the control unit 190 outputs the setting information and setting parameters received from the worker in step S509 to the long-distance communication unit 130 to request an update, and the process proceeds to step S511.

[0078] In response to this, in the long-distance communication section 130 , the above request is accepted by the communication unit control section 1310 , and the acquired setting information and setting parameters are recorded in the storage section 1320 as communication setting information 1322 .

[0079] In step S511, the control unit 190 controls the long-distance communication unit 130 to perform a communication test with the pump management device 200, and then proceeds to step S512.

[0080] As a result, the long-distance communication unit 130 performs a communication test with the pump management device 200. When the pump management device 200 normally receives a request for a communication test from the pump device 100, the pump management device 200 responds with an indication that the test was successful.

[0081] In step S512, the control unit 190 determines whether or not the long-distance communication unit 130 has received a response indicating the success of the test from the pump management device 200. If a response indicating the success of the test has been received, the process proceeds to step S513. On the other hand, if the response has not been received, the process proceeds to step S514.

[0082] In step S513, the control unit 190 controls the display unit 120 to display a completion message indicating that communication with the pump management device 200 has become possible, and records (updates) the SIM information 1321 acquired in step S501 as SIM information 1601 in the memory unit 160, and terminates the process.

[0083] As a result, the operator who sees the completion display recognizes that the pump device 100 is now in a state where it can communicate with the pump management device 200. In addition, the SIM information 1601 and the communication setting information 1602 stored in the storage unit 160 have been updated to information on a combination that allows communication.

[0084] In step S514, the control unit 190 retries the communication test, and the process proceeds to step S515. That is, the control unit 190 controls the long-distance communication unit 130 to perform a test for communication with the pump management device 200 again, and the process proceeds to step S515.

[0085] This causes the long-distance communication unit 130 to again perform a communication test with the pump management device 200. When the pump management device 200 has normally received a request for a communication test from the pump device 100, the pump management device 200 responds with an indication that the test was successful.

[0086] In step S515, the control unit 190 determines whether or not the long-distance communication unit 130 has received a response indicating the success of the test from the pump management device 200. If a response indicating the success of the test has been received, the process proceeds to step S513. On the other hand, if the response has not been received, the process proceeds to step S516.

[0087] In step S516, the control unit 190 controls the display unit 120 to display NG, which indicates that communication with the pump management device 200 is not possible, and proceeds to step S509 to request manual configuration. As a result, the operator who sees the NG display recognizes that the pump device 100 is not in a state where it can communicate with the pump management device 200 and that manual configuration is required.

[0088] As described above, in this embodiment, in the pump device 100, information on the SIM card set in the long-distance communication unit 130 and communication setting information set in the long-distance communication unit 130 are backed up and stored in the memory unit 160, and the backed up information is then set in the long-distance communication unit 130 when instructions are received from an operator, when long-distance wireless communication cannot be performed normally, when the communication unit equipped with the long-distance communication unit 130 is replaced, etc.

[0089] Therefore, according to the above-mentioned pump device 100, when communication setting information needs to be set in the long-distance communication unit 130 for some reason, the setting information used when long-distance communication was previously performed is automatically set in the long-distance communication unit 130, so that the worker can complete the communication setting with little burden and the maintenance burden related to communication can be reduced.

[0090] In the above embodiment, if the SIM card 1330 has not been changed, the information stored as a backup is set; otherwise, at the discretion of the worker, the information stored as a backup or information manually entered can be set.

[0091] In addition, in the above embodiment, test communication is started after communication setting information is set in the long-distance communication unit 130, so that the worker can aim to complete the work with little burden. Furthermore, since the results of the test communication are notified by display, the worker can easily recognize the progress of the work.

[0092] 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.

[0093] For example, in the above embodiment, in step S502, the SIM information is strictly judged to match, but the present invention is not limited to this. For example, it may be judged whether the SIM information 1601 stored in the storage unit 160 and the SIM information 1321 acquired in step S501 are the same carrier. If they are the same carrier, there is a high possibility that communication can be performed normally by setting the information stored as a backup.

[0094] Furthermore, in the communication setting process shown in FIG. 5, if backup information is not stored in memory unit 160, control unit 190 may control display unit 120 to display an error message indicating that backup information is not stored, and terminate the process.

[0095] 5, the replacement of a communication unit equipped with long-distance communication unit 130 is given as an example of a trigger for starting the communication setup process. As a method for determining whether or not a replacement has occurred, control unit 190 may read out the model number and serial number from the communication unit and record them in storage unit 160, and when it detects a connection of a communication unit with a different model number and serial number, it may start the above-mentioned communication setup process.

[0096] Furthermore, when the SIM information does not match (when the SIM card 1330 is replaced), instructions are received from the worker in step S505, but the present invention is not limited to this.

[0097] For example, the process may proceed to step S509 and new settings may be accepted without waiting for instructions from an operator. It goes without saying that various modifications can be made without departing from the spirit and scope of the present invention. [Explanation of symbols]
