Description

The present invention relates to data backup.

For example, various types of equipment such as water supply devices may have variable parameters set at the time of installation. By setting appropriate parameters for a device, it is possible to cause the device to perform operations appropriate for its usage environment. Even after replacing a device or its parts (for example, a control board or an electrical component including the same), the parameters before replacement may continue to be set. For example, when a malfunction occurs in a device, a worker may adjust the parameters of the device, but if the adjusted parameters are found to be inappropriate, the unadjusted parameters may be changed to the device. It may be reconfigured.

However, conventionally, parameters set in devices have been managed in various ways. For example, labels containing parameters may be affixed to devices, or may be recorded in separate documents or electromagnetically, or may not be managed at all. If parameter management methods are not unified in this way, it will be difficult for workers to efficiently identify the parameters set in the equipment when necessary, for example, when replacing equipment or its parts or adjusting parameters. It is expected that this will be difficult. Therefore, it is desirable to manage device parameters in a unified manner.

Patent Document 1 discloses a technique for backing up and restoring data for MFPs (Multifunction Peripherals). Specifically, according to [0021] of Patent Document 1, the data backup servers 400A to 400C have a storage device 403 that stores backup information a1 to a3 acquired from the MFP 100 side. a3 includes device-specific information for identifying MFP 100 and backup (specific) data having identification information. That is, according to the technique disclosed in Patent Document 1, backup data of a large number of MFPs 100 can be managed in a unified manner by data backup servers 400A to 400C.

JP2018-84944A

Patent Document 1 does not envisage replacing the MFP 100 or its parts, much less carrying over the backup data before the replacement even after the replacement. If the MFP 100 or its parts with certain device-specific information are replaced with MFPs or parts with different device-specific information, backup data corresponding to the former device-specific information is immediately obtained from the latter device-specific information. I can't.

An object of the present invention is to automatically take over and manage backup data of a device even after the device or its parts are replaced.

The first acquisition unit acquires an initial setting request including first identification data and second identification data different from the first identification data. The registration unit stores the second identification data in the first storage in association with first key data that is key data associated with the first identification data in the first storage in response to the initial setting request. Register in the department.

A backup server according to another aspect of the present invention includes a storage unit, an acquisition unit, and a registration unit. The storage unit stores the identification data in association with the backup data. The acquisition unit acquires an initialization request including first identification data and second identification data different from the first identification data. The registration unit registers the second identification data in the storage unit in response to the initial setting request in association with first backup data that is backup data associated with the first identification data in the storage unit.

In addition, branch numbers may also be used.

Note that in the following description, for convenience, it is assumed that the device to be data backed up is a water supply device, but the device is not limited to a water supply device. For example, the equipment may be a pump device for any purpose such as water pumping, drainage, compression, etc., or various electrical or mechanical equipment other than the pump device, such as computers, OA (Office Automation) equipment, home appliances, It may also be a robot, industrial machine, etc.

(First embodiment)
As illustrated in FIG. 1, the backup system according to the first embodiment includes a backup server 100, terminals 200-1, 200-2, 200-3, . -2,300-3,300-4,300-5,300-6,...

Note that the number of each device in FIG. 1 is merely an example. For example, the backup server 100 may be redundant as multiple servers, and the number of terminals 200 and water supply devices 300 is arbitrary, so the number of terminals 200 may be more or less than three. , the number of water supply devices 300 may be greater or less than six.

The terminal 200 can be connected to the backup server 100 via a network using, for example, a wireless communication technology such as mobile communication (for example, 3G, 4G, 5G, mobile WiMAX), wireless LAN (Local Area Network), or WiMAX. . Furthermore, the terminal 200 connects the water supply device 300 to the water supply device 300 using a (near field) wireless communication technology such as Bluetooth (registered trademark), wireless LAN, NFC (Near Field Communication), or wired communication technology such as USB (Universal Serial Bus). It is possible to connect to

The terminal 200 requests the water supply device 300 for identification data that identifies the water supply device 300 (or its parts such as a control board), and requests backup data such as parameters set in the water supply device 300. A data acquisition command is issued and sent to the water supply device 300. The terminal 200 issues various requests to the backup server 100 based on the data received from the water supply device 300.

Then, the terminal 200 transmits a backup request, which will be described later, to the backup server 100 in order to register backup data of the water supply device 300, and transmits a search request, which will be described later, to the backup server 100, in order to restore the parameters of the water supply device 300. or sends an initial setting request, which will be described later, to the backup server 100 in order to carry over registered backup data for the water supply device 300 even after the water supply device 300 or its parts are replaced.

Furthermore, when restoring data such as parameters of the water supply device 300, the terminal 200 receives backup data including the parameters of the water supply device 300 from the backup server 100 in response to the search request, and transfers the parameters to the water supply device 300. A parameter setting command for setting may be issued and transmitted to the water supply device 300.

The backup server 100 manages backup data for each water supply device 300. Specifically, the backup server 100 registers the backup data of the terminal 200 in an internal database in response to a backup request received from the terminal 200, or registers the backup data of the corresponding water supply device 300 in response to a search request received from the terminal 200. The backup data can be searched from this database and returned to the terminal 200, or the identification data of the new (for example, after replacement) water supply device 300 can be sent to the existing (for example, before replacement) water supply device in response to an initial setting request received from the terminal 200. 300 identification data. In this way, "initial setting" associates two pieces of identification data, so it can also be called "link setting" or the like.

Specifically, the backup server 100 according to the first embodiment has a first database in which backup data of the water supply device 300 is associated with key data for indexing, and a first database in which the backup data of the water supply device 300 is associated with the identification data of the water supply device 300. A second database is being constructed. As will be described later, the initial setting request includes link source identification data that has already been registered in the second database and link destination identification data that will be newly associated with this link source identification data. The backup server 100 searches the second database for key data associated with the link source identification data included in the initial setting request, associates the link destination identification data included in the initial setting request with this key data, and stores the second database. Register in the database. Therefore, after the initial setting request is successfully processed, when the backup server 100 receives a search request that includes link destination identification data, it retrieves the same key data associated with the link source identification data from the second database. It becomes possible to search for the key data of the water supply device 300 associated with this key data from the first database, that is, identified by the link source identification data, and return it to the terminal 200. That is, even after the water supply device 300 or its parts identified by the link source identification data is replaced with the water supply device 300 or its parts identified by the link destination identification data, the backup data of the former water supply device 300 is inherited. Can be done.

The water supply device 300 includes an electrical component including a storage section, as will be described later, and identification data of the water supply device 300 is written into this storage section, for example, at the time of manufacturing, shipping, delivery, etc. There is. Then, in response to a data acquisition command from the terminal 200, for example, the water supply device 300 reads out its own identification data, data to be backed up to the backup server 100 (for example, set parameters), etc. from the storage unit, Send to terminal 200. Further, the water supply device 300 receives a command such as a parameter setting command from the terminal 200, and performs, for example, setting parameters in accordance with the command.

Hereinafter, the configuration and operation of the backup server 100, terminal 200, and water supply device 300 in FIG. 1 will be explained in order using the drawings.
First, a configuration example of the backup server 100 will be described. Backup server 100 is, for example, a server computer. The backup server 100 includes a processor (for example, a CPU (Central Processing Unit), an FPGA ( Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit), etc.). Furthermore, the backup server 100 includes a memory that temporarily stores programs executed by a processor and data used by the processor to implement such processing.

The backup server 100 can further utilize a communication I/F (interface) for connecting to an external device. The communication I/F may be built into the backup server 100 or may be externally attached to the backup server 100.

The communication I/F communicates with the terminal 200 via a network, typically the Internet. The communication I/F receives various requests from the terminal 200 and transmits responses to the requests to the terminal 200.

The backup server 100 can further utilize an auxiliary storage device for storing data. The auxiliary storage device may be built into the backup server 100 or may be externally attached to the backup server 100.

The auxiliary storage device stores, for example, identification data, key data, backup data, etc. that are registered based on a request received from the terminal 200 or another communication device (not shown). The auxiliary storage device is preferably a nonvolatile storage medium such as a HDD (Hard Disk Drive), an SSD (Solid State Drive), or a flash memory. Alternatively, the auxiliary storage device may be a file server connected to the backup server 100 via a network.

The backup server 100 can further utilize an input I/F for receiving user input. The input I/F may be built into the backup server 100 or may be externally attached to the backup server 100.

The input I/F may be, for example, a keyboard, mouse, numeric keypad, microphone, camera, etc., or may have an output I/F function such as a touch screen. User input typically may be a tap, click, drag, press of a particular key, etc. Additionally, user input may include, for example, audio captured by a microphone.

Next, the description of the configuration example of the backup server 100 will be continued using FIG. 2. The backup server 100 in FIG. 2 includes an initial setting request acquisition unit 101, a backup request acquisition unit 102, a search request acquisition unit 103, a data registration unit 104, a key data storage unit 105, a backup data storage unit 106, It includes a data search section 107 and a request response section 108.

The initial setting request acquisition unit 101 acquires an initial setting request. The initial setting request includes link source identification data registered in the database constructed in the key data storage unit 105 and link destination identification data different from this. Typically, the initial setting request may be issued when the water supply device 300 (or its parts such as electrical components) is replaced, and in this case, the link source identification data is data that identifies the water supply device 300 before replacement. , the link destination identification data is data for identifying the water supply device 300 after replacement. The initial setting request acquisition unit 101 may receive an initial setting request from the terminal 200, and for example, acquires an initial setting request based on user input such as key input, image (including barcode) reading, etc. It is possible to do so. That is, the initial setting request acquisition unit 101 may correspond to the above-mentioned communication I/F and/or input I/F. The initial setting request acquisition unit 101 sends an initial setting request to the data registration unit 104.

Note that the identification data included in various requests may be hashed. As a result, even if the data stored in the key data storage unit 105 and/or the backup data storage unit 106 is leaked for some reason, it is possible to identify which water supply device 300 each backup data belongs to. can be prevented.

The backup request acquisition unit 102 acquires a backup request. The backup request includes identification data and backup data. A backup request may typically be issued when the water supply device 300 is installed for the first time, when parameters of the water supply device 300 are changed, or the like. The backup request acquisition unit 102 may receive a backup request from the terminal 200, or may acquire a backup request based on user input such as key input, image (including barcode) reading, etc. could be. That is, the backup request acquisition unit 102 may correspond to the above-mentioned communication I/F and/or input I/F. The backup request acquisition unit 102 sends the backup request to the data registration unit 104.

The search request acquisition unit 103 acquires a search request. The search request includes identification data. The search request may typically be issued when restoring data such as parameters of the water supply device 300. The search request acquisition unit 103 receives a search request from the terminal 200, for example. That is, the search request acquisition unit 103 may correspond to the above-mentioned communication I/F. The search request acquisition unit 103 sends the search request to the data search unit 107.

The data registration unit 104 may correspond to the processor described above. The data registration unit 104 registers data (entries) in the database constructed in the key data storage unit 105 and/or the backup data storage unit 106 in response to various requests, such as initial setting requests, backup requests, etc. .

The data registration unit 104 receives an initial setting request from the initial setting request acquisition unit 101. The data registration unit 104 searches a database built in the key data storage unit 105 for first key data that is key data associated with the link source identification data included in the initial setting request. Then, the data registration unit 104 associates the link destination identification data included in the initial setting request with this first key data and registers it in the database (that is, registers it in the key data storage unit 105).

Specifically, the key data storage unit 105 may store a key data table (DB) including entries e11, e12, e13, . . . as illustrated in FIG. Here, it is assumed that the initial setting request includes id_b1 as link source identification data and id_b2 as link destination identification data. In this case, the data registration unit 104 searches this key data table for key_2, which is key data associated with id_b1 as the link source identification data. Then, the data registration unit 104 copies this key data, associates id_b2 as link destination identification data with it, and registers it as a new entry in the table. Thereby, it becomes possible to search and restore the backup data of the water supply device 300 identified by id_b1 as the link source identification data based on id_b2 as the link destination identification data.

Note that if the initial setting request has been received from any of the terminals 200, the data registration unit 104 issues an initial setting completion notification as a response to this initial setting request after completing the registration of the link destination identification data. It may also be sent to the request response unit 108. Alternatively, after completing the registration of the link destination identification data, the data registration unit 104 reads the backup data associated with the first key data in the database constructed in the backup data storage unit 106 in response to this initial setting request. , may be sent to the request response unit 108. According to the latter response, the terminal 200 can acquire the backup data of the water supply device 300 identified by the link destination identification data without issuing a search request. This is useful, for example, when replacing the water supply device 300, in addition to taking over backup data, the parameters of the water supply device 300 before replacement are set in the water supply device 300 after replacement.

The data registration unit 104 receives a backup request from the backup request acquisition unit 102. The data registration unit 104 first searches the database built in the key data storage unit 105 for key data associated with the identification data included in the backup request. If the search is successful, the data registration unit 104 associates the backup data included in the backup request with this key data and registers it in the database constructed in the backup data storage unit 106 (i.e., the backup data storage 106).

On the other hand, if the search fails, specifically if the identification data included in the backup request is not registered in the database constructed in the key data storage unit 105, the data registration unit 104 stores information in this database. New key data different from any registered key data can be issued, and this identification data can be associated with the new key data and registered in this database.

Note that if a backup request has been received from any of the terminals 200, the data registration unit 104 issues a backup completion notification as a response to the backup request after completing registration of the backup data, and sends the notification to the request response unit 108. You can send it.

The key data storage unit 105 stores identification data in association with key data. For example, the key data storage unit 105 may store identification data and key data in a table format. This table can also be called a database. In the key data storage unit 105, each identification data is associated with one key data. That is, none of the identification data is associated with multiple pieces of key data. On the other hand, in the key data storage unit 105, key data may be redundantly associated with a plurality of identification data. The key data storage unit 105 may correspond to the aforementioned memory and/or auxiliary storage device.

Identification data and key data can be written into the key data storage section 105 by the data registration section 104. Further, the data stored in the key data storage unit 105 can be read (including searching) by the data registration unit 104 and the data search unit 107.

The backup data storage unit 106 stores key data in association with backup data. For example, the backup data storage unit 106 may store key data and backup data in a table format. This table can also be called a database. Specifically, the backup data storage unit 106 may store a backup data table (DB) including entries e21, e22, e23, . . . as illustrated in FIG. Backup data storage 106 may correspond to the memory and/or auxiliary storage described above. Here, the backup data is not limited to the backup data itself, but may also be data indicating the location of the backup data body, such as a URL (Uniform Resource Locator).

The backup data storage unit 106 can have key data and backup data written therein by the data registration unit 104 . Further, the data stored in the backup data storage unit 106 can be read (including searching) by the data registration unit 104 and the data search unit 107.

The data search unit 107 may correspond to the processor described above. The data search unit 107 retrieves index data, such as identification data, key data, from the database constructed in the key data storage unit 105 and/or the backup data storage unit 106 in response to various requests, such as search requests. Find data associated with , etc.

The data search unit 107 receives a search request from the search request acquisition unit 103. The data search unit 107 first searches the database built in the key data storage unit 105 for key data associated with the identification data included in the search request. Furthermore, the data search unit 107 searches the database constructed in the backup data storage unit 106 for backup data associated with this key data.

Note that if the search request has been received from any of the terminals 200, the data search unit 107 may send the backup data to the request response unit 108 in response to the search request after completing the backup data search. good.

The request response unit 108 receives responses to various requests sent from the terminal 200 from the data registration unit 104 or the data search unit 107, and returns them to the terminal 200 (that is, sends them to the terminal 200 via the network). ). The request response unit 108 may correspond to the above-mentioned communication I/F.

For example, the request response unit 108 may receive an initialization completion notification or backup data from the data registration unit 104 and return this to the terminal 200 as a response to the initialization request. The backup data here is backup data that is associated with certain key data in the database built in the backup data storage unit 106, and this key data is initialized in the database built in the key data storage unit 105. It is associated with the link source identification data included in the setting request.

Further, the request response unit 108 can receive a backup completion notification from the data registration unit 104 and return it to the terminal 200 as a response to the backup request.

Furthermore, the request response unit 108 can receive backup data from the data search unit 107 and return it to the terminal 200 as a response to the search request. The backup data here is backup data associated with certain key data in the database built in the backup data storage unit 106, and this key data can be searched in the database built in the key data storage unit 105. Associated with identification data included in the request.

Next, a configuration example of the terminal 200 will be explained.

The terminal 200 includes a processor that issues requests to the backup server 100, issues commands to the water supply device 300, manages a local database described below, and the like. Furthermore, the terminal 200 includes a memory that temporarily stores a program executed by a processor to implement such processing, data used by the program, and the like.

Terminal 200 can further utilize a communication I/F for connecting to an external device. The communication I/F may be built into the terminal 200 or may be externally attached to the terminal 200.

The communication I/F communicates with the backup server 100 via a network, typically the Internet, using communication technologies such as mobile communication, wireless LAN, and WiMAX. The communication I/F transmits various requests to the backup server 100 and receives responses to the requests from the backup server 100.

Further, the communication I/F communicates with the water supply device 300 using a (short distance) wireless communication technology or a wired communication technology. The communication I/F transmits various commands to the water supply device 300 and receives responses from the water supply device 300 to the commands (for example, may include identification data and/or backup data).

Note that the communication I/F for connecting to the backup server 100 may be the same as the communication I/F for connecting to the water supply device 300, or may be different. For example, the former may be a 4G module and the latter may be a Bluetooth module.

Terminal 200 can further utilize auxiliary storage for storing data. The auxiliary storage device may be built into the terminal 200 or may be externally attached to the terminal 200.

The auxiliary storage device can store various data, such as a local database (DB) described later. By using such a local DB, even in situations where it is difficult for the terminal 200 to connect to the backup server 100, such as when the water supply device 300 is installed underground, restoration processing based on data downloaded in advance from the backup server 100 can be performed. , etc. are possible.

Terminal 200 can further utilize an input I/F for receiving user input. The input I/F may be built into the terminal 200 or may be externally attached to the terminal 200.

The identification data acquisition unit 201 may receive identification data from the water supply device 300, and may acquire identification data based on user input such as key input, image (including barcode) reading, etc. It is also possible. That is, the identification data acquisition unit 201 may correspond to the above-mentioned communication I/F and/or input I/F. Note that the water supply device 300 may transmit its own identification data in response to an identification data acquisition command from the terminal 200, or may voluntarily transmit its own identification data, for example, like a beacon signal in wireless communication technology. Alternatively, the information may be displayed in a format readable by the terminal 200. The identification data acquisition unit 201 sends identification data to the request issuing unit 203.

The backup data acquisition unit 202 acquires backup data such as parameters set in the water supply device 300. The backup data acquisition unit 202 may receive backup data from the water supply device 300, and may acquire backup data based on user input such as key input, image (including barcode) reading, etc. It is also possible. That is, the backup data acquisition unit 202 may correspond to the above-mentioned communication I/F and/or input I/F. Note that the water supply device 300 may transmit its own backup data in response to a backup data acquisition command from the terminal 200, or may voluntarily transmit its own backup data, for example, like a beacon signal in wireless communication technology. It is possible to do so. The backup data acquisition unit 202 sends the backup data to the request issuing unit 203.

The request issuing unit 203 can receive identification data from the identification data acquisition unit 201 and backup data from the backup data acquisition unit 202. The request issuing unit 203 issues various requests based on the received data. For example, the request issuing unit 203 may issue an initial setting request based on the identification data of two different water supply devices 300, issue a backup request based on the identification data and backup data of a certain water supply device 300, or issue a backup request based on the identification data and backup data of a certain water supply device 300. A search request may be issued based on the identification data of the device 300. The request issuing unit 203 basically sends the issued request to the communication unit 204, but can send a search request to the local DB management unit 207 when searching the local DB. The request issuing unit 203 may correspond to the processor described above.

The request issuing unit 203 can issue various requests, for example, using user input as a trigger. The user input here is, for example, pressing a button such as "replace water supply device", "back up data", or "restore data" that is displayed on the screen of the terminal 200 by a water supply device management application executed by the processor. obtain. In response to such a trigger, the request issuing unit 203 can instruct the command issuing unit 205 to issue a necessary data acquisition command.

For example, the communication unit 204 receives various requests from the request issuing unit 203 and transmits them to the backup server 100. Note that when a request cannot be sent to the backup server 100, such as in an offline environment, or when the sending fails, the issued request may be temporarily saved. Then, when establishing a connection between the communication unit 204 and the backup server 100, the communication unit 204 may (re)send the request to the backup server 100.

Furthermore, the communication unit 204 can receive a response to a transmitted request from the backup server 100 and send it to the command issuing unit 205. For example, the communication unit 204 may send backup data (which may include parameters that can be set in the water supply device 300) to the command issuing unit 205 as a response to the transmitted initial setting request or search request.

Furthermore, the communication unit 204 can receive (download) data to be stored in the local DB storage unit 208 from the backup server 100 and send it to the local DB management unit 207. For example, in order to restore data such as parameters in an offline environment, some or all of the database entries built in the key data storage unit 105 and the backup data storage unit 106 of the backup server 100 may be saved in advance by the terminal 200. Can be downloaded.

The command issuing unit 205 issues various commands for controlling the water supply device 300 and sends them to the command transmitting unit 206. For example, the command issuing unit 205 may receive backup data including parameters from the communication unit 204 as a response to a transmitted initial setting request or search request. The command issuing unit 205 can then issue a parameter setting command for setting this parameter to the water supply device 300. Here, this water supply device 300 is identified by link destination identification data included in the initial setting request or identification data included in the search request. Further, the command issuing unit 205 may issue an identification data/backup data acquisition command in order for the identification data acquisition unit 201 and/or the backup data acquisition unit 202 to acquire identification data and/or backup data.

Next, a configuration example of the water supply device 300 will be explained. The water supply device 300 has a built-in electrical component. This electrical component may be independently replaceable. In other words, it may be possible to replace only the electrical component with a new one while maintaining other mechanical or electrical components of the water supply device 300, such as the pump and motor. In this case, the identification data of the water supply device 300 may change before and after replacing its electrical component. The electrical unit of the water supply device 300 includes a processor that reads and writes various data such as identification data and backup data, executes commands, controls motors, and the like. Further, the electrical equipment section of the water supply device 300 includes a memory that temporarily stores programs executed by a processor and data used by the processor in order to implement such processing. The processor and memory may be integrated as a microcontroller, for example.

The electrical equipment section of the water supply device 300 can further utilize a communication I/F for connecting to an external device. The communication I/F may be built into the water supply device 300 or may be externally attached to the water supply device 300.

The communication I/F may be any interface that can communicate with the communication I/F used by the terminal 200, for example. For example, the communication I/F communicates with the terminal 200 using (short-range) wireless communication technology or wired communication technology. The communication I/F transmits identification data and backup data (which may include parameters) of the water supply device 300 (or its electrical component) to the terminal 200, and receives commands from the terminal 200.

The water supply device 300 can further utilize an auxiliary storage device for storing data. The auxiliary storage device may be built into the water supply device 300 or may be externally attached to the water supply device 300.

The auxiliary storage device stores, for example, identification data and parameters of the water supply device 300. Preferably, the auxiliary storage device is a non-volatile storage medium. Note that the identification data may be written in, for example, a ROM built into the microcontroller when the water supply device 300 is manufactured, shipped, delivered, or when the water supply device 300 or its electrical component is replaced. Writing of these data may be performed using either wired or wireless communication.

Here, the identification data of the water supply device 300 includes, for example, format data corresponding to the product name of the water supply device 300 and/or a product number encoded with the format data, and individual identification of the water supply device 300 or its electrical component. It may include a manufacturing number corresponding to the number. These data make it possible to identify which individual of which product the water supply device 300 is. Note that the product number and manufacturing number do not necessarily have to be separate data elements, and may be designed so that both the product and the individual can be identified from one number.

Next, the description of the configuration example of the water supply device 300 will be continued using FIG. 4. Water supply device 300 in FIG. 4 includes a pump 301, a motor 302, and an electrical component 310. The motor 302 is connected to an electrical equipment section 310 via a signal line, and its rotational speed and the like are controlled by the electrical equipment section 310. Pump 301 is connected to the rotating shaft of motor 302.

In the example of FIG. 4, the pump 301 is a water supply pump, but when replacing the water supply device 300 with another pump device, the pump 301 may be replaced with any type of pump. That is, the pump 301 may be used for pumping water, draining water, compressing water, or the like. Further, the pump 301 is not limited to water, and can handle any fluid such as gas. Furthermore, as described above, the water supply device 300 is only an example of a device to which this embodiment is applicable, and the water supply device 300 can be replaced with other devices.

The electrical equipment section 310 includes a control section 311 , a communication section 312 , an identification data storage section 313 , and a parameter storage section 314 .

The control unit 311 controls various functional units inside the motor 302 and the electrical equipment unit 310, performs input/output, and performs various calculations. The control unit 311 may correspond to the processor described above.

Specifically, the control unit 311 transmits information from the communication unit 312 or an input I/F (not shown) at the time of manufacturing, shipping, or delivery of the water supply device 300, or when replacing the water supply device 300 or its electrical component 310. A request to write identification data of the water supply device 300 or its electrical equipment section 310 is received, and the identification data is stored in the identification data storage section 313.

Further, the control unit 311 can control the rotation speed of the motor 302, etc., based on, for example, pressure and flow rate detected by a detection device (not shown), and/or parameters stored in the parameter storage unit 314.

Further, the control unit 311 receives a command for setting parameters from the communication unit 312, and sets the parameters in accordance with the command. For example, the control unit 311 rewrites the parameters stored in the parameter storage unit 314, writes new parameters, or deletes the stored parameters.

Furthermore, the control unit 311 reads the identification data stored in the identification data storage unit 313 and/or the parameters stored in the parameter storage unit 314, and transmits them to the terminal 200 via the communication unit 312, or 200 may be displayed in a readable format. Such an operation may be performed spontaneously or may be triggered by a data acquisition command from the terminal 200. Further, the control unit 311 may create backup data that includes, for example, date and time data in addition to the read parameters, and send it to the communication unit 312.

The communication unit 312 exchanges various data with the terminal 200. For example, the communication unit 204 may receive an acquisition command for identification data and/or backup data (which may include parameters), a parameter setting command, etc. from the terminal 200 and send the received data to the control unit 311. On the other hand, the communication unit 312 can receive identification data and/or backup data from the control unit 311 and transmit it to the terminal 200. The communication unit 312 may correspond to the above-mentioned communication I/F.

The identification data storage section 313 stores identification data that uniquely identifies the water supply device 300 or its electrical equipment section 310. The identification data is read and written by the control unit 311. However, if the identification data is to remain unchanged, the writing of the identification data by the control unit 311 may be limited to one time. The identification data storage unit 313 may correspond to the aforementioned memory (but preferably non-volatile memory) and/or auxiliary storage.

The parameter storage unit 314 stores parameters set in the water supply device 300. The parameters are read and written by the control unit 311. Parameter storage unit 314 may correspond to the aforementioned memory and/or auxiliary storage device.

An example of the operation of the backup system in FIG. 1 will be described below with reference to FIGS. 7 to 9.
FIG. 7 illustrates the operation of the system when registering backup data. Such an operation can be started, for example, by a worker in charge of the water supply device 300 operating the terminal 200 to back up data such as the parameters after setting/adjusting the parameters.

The terminal 200 issues identification data and a backup data acquisition command, and transmits them to the water supply device 300 (step S401). Note that step S401 can be omitted if the water supply device 300 voluntarily transmits such data or displays it in a format readable by the terminal 200, or if the worker directly inputs such data.

Water supply device 300 returns identification data and backup data to terminal 200 in response to the command in step S401 (step S402). Note that if the worker directly inputs such data, step S402 can be omitted.

The terminal 200 issues a backup request including the identification data and backup data received in step S402 (step S404). Then, the terminal 200 transmits the issued backup request to the backup server 100 (step S405). Note that the terminal 200 may optionally temporarily store the issued backup request. Thereby, even in an environment where the terminal 200 cannot access the backup server 100, it is possible to resend the backup request later. Further, as described above, the backup request may be input directly to the backup server 100. In this case, steps S401 to S405 and step S409, which will be described later, can be omitted.

The backup server 100 searches, for example, the aforementioned key data table (DB) for key data associated with the identification data included in the backup request in step S405 (step S406). Note that if the key data search fails in step S406, the backup server 100 issues new key data that is different from any of the registered key data, and includes this new key data in the backup request. It may be registered in association with identification data (step S407).

The backup server 100 associates the backup data included in the backup request in step S405 with the key data searched in step S406 or the new key data registered in step S407, for example, in the aforementioned backup data table (DB). (Step S408). Then, the backup server 100 returns a backup completion notification to the terminal 200 (step S409).

FIG. 8 illustrates the operation of the system during data restoration. Such an operation may occur, for example, when a worker in charge of the water supply device 300 adjusts parameters on a trial basis, or when set parameters are lost due to a malfunction in the auxiliary storage device serving as the parameter storage section 314, etc. It can be started by operating the terminal 200 to restore backed up data about the water supply device 300.

The terminal 200 issues an identification data acquisition command and transmits it to the water supply device 300 (step S411). Note that step S411 can be omitted if the water supply device 300 voluntarily transmits such data or displays it in a format readable by the terminal 200, or if the worker directly inputs such data.

The water supply device 300 returns identification data to the terminal 200 in response to the command in step S411 (step S412). Note that if the worker directly inputs such data, step S412 can be omitted.

The terminal 200 issues a search request including the identification data received in step S412 (step S413). Then, the terminal 200 transmits the issued search request to the backup server 100 (step S415).

Note that, as an option, the terminal 200 may search a local DB downloaded in advance from the backup server 100 based on the issued search request (step S414). This makes it possible to restore data even in an offline environment, and even when online, data can be restored faster than when data is exchanged with the backup server 100. If the search in step S414 is successful, step S415 and steps S416 to S418, which will be described later, can be omitted.

The backup server 100 searches, for example, the aforementioned key data table (DB) for key data associated with the identification data included in the search request in step S415 (step S416). Further, the backup server 100 searches, for example, the backup data table (DB) described above for backup data associated with the key data searched in step S416 (step S417). Then, the backup server 100 returns the searched backup data (including parameters) to the terminal 200 as a search response (step S418).

Based on the search response in step S418, the terminal 200 issues a parameter setting command for setting the parameters included in the search response in the water supply device 300 (step S419). The terminal 200 transmits a parameter setting command to the water supply device 300 (step S420).

The water supply device 300 sets (updates) parameters according to the parameter setting command in step S420 (step S421). Then, the water supply device 300 returns a parameter setting completion notification to the terminal 200 (step S422).

FIG. 9 illustrates the operation of the system at the time of initial setting (link setting). Such an operation is, for example, when a worker in charge of the water supply device 300 operates the terminal 200 to set a link between identification data before and after replacement, when the water supply device 300 or its electrical component 310 is replaced/replaced. You can start with In the example of FIG. 9, a link is set between the identification data of water supply device 300-b2 and the identification data of water supply device 300-b1.

The terminal 200 issues an identification data acquisition command and transmits it to the water supply device 300-b1 and the water supply device 300-b2 (step S431 and step S433). Note that when the water supply device 300-b1 and/or the water supply device 300-b2 voluntarily transmits such data or displays it in a format readable by the terminal 200, or when a worker directly inputs such data, In this case, step S431 and/or step S433 can be omitted.

The water supply device 300-b1 returns identification data to the terminal 200 in response to the command in step S431 (step S432). Note that if the worker directly inputs such data, step S432 can be omitted.

The water supply device 300-b2 returns identification data to the terminal 200 in response to the command in step S433 (step S434). Note that if the worker directly inputs such data, step S434 can be omitted.

The terminal 200 issues an initialization request including the identification data received in steps S432 and S434 as link source identification data and link destination identification data, respectively (step S436). Then, the terminal 200 transmits the issued initial setting request to the backup server 100 (step S437). Note that, as an option, the terminal 200 may temporarily save the issued initial setting request. Thereby, even in an environment where the terminal 200 cannot access the backup server 100, it is possible to resend the initial setting request later. Further, as described above, the initial setting request may be input directly to the backup server 100. In this case, steps S431 to S434 and step S439 or steps S440 to S445, which will be described later, can be omitted.

The backup server 100 searches, for example, the aforementioned key data table (DB) for key data associated with the link source identification data included in the initial setting request in step S437, and searches this key data for the link included in the initial setting request. It is registered in the key data table in association with the destination identification data (step S438).

As an option, after step S438, the backup server 100 may send an initialization completion notification to the terminal 200 as an initialization response (step S439). In this case, steps S440 to S445, which will be described later, can be omitted. Alternatively, as will be described later using steps S440 to S445, the system may search for the water supply device 300-b1 in the water supply device 300-b2 without waiting for a search request that includes the identification data of the water supply device 300-b2. Backup data may be automatically restored.

In step S440, the backup server 100 searches the backup data table (DB) described above for backup data associated with the key data registered in step S438. Then, the backup server 100 returns the searched backup data (including parameters) to the terminal 200 as an initial setting response (step S441).

Based on the initial setting response in step S441, the terminal 200 issues a parameter setting command for setting the parameters included in the initial setting response in the water supply device 300 (step S442). The terminal 200 transmits a parameter setting command to the water supply device 300 (step S443).

The water supply device 300 sets parameters according to the parameter setting command in step S443 (step S444). Then, the water supply device 300 returns a parameter setting completion notification to the terminal 200 (step S445).

As described above, the backup system according to the first embodiment does not directly associate the backup data of a device with the identification data of the device, but indirectly associates the backup data with the identification data of the device. Then, this backup system associates identification data of a plurality of different devices targeted for link setting with the same key data. Therefore, according to this backup system, for example, the identification data of the device before replacement and the identification data of the device after replacement can be associated with the same key data. It becomes possible to restore the backup data of the previous device. That is, the backup data of a device can be automatically taken over and managed even after the device or its parts are replaced.

(Second embodiment)
The backup system according to the first embodiment described above makes it possible to restore the backup data of the device before replacement by using the key data, for example, using the identification data of the device after replacement. On the other hand, the backup system according to the second embodiment can achieve similar effects without using key data. The backup system according to the present embodiment includes a backup server 500 instead of the backup server 100 in the backup system according to the first embodiment.

Backup server 500 has the same or similar hardware configuration as backup server 100, but differs in at least part of its functional configuration and operation. The description of the configuration example of the backup server 500 will be continued using FIG. 10. The backup server 500 in FIG. 10 includes an initial setting request acquisition unit 501, a backup request acquisition unit 502, a search request acquisition unit 503, a data registration unit 504, a backup data storage unit 506, a data search unit 507, and a request It includes a response section 508 and a data deletion section 509. Among these, the initial setting request acquisition unit 501, the backup request acquisition unit 502, the search request acquisition unit 503, and the request response unit 508 may be the same or similar to the elements with the same names in FIG. 2, respectively.

The data registration unit 504 may correspond to the processor described above. The data registration unit 504 registers data (entries) in a database constructed in the backup data storage unit 506 in response to various requests, such as initial setting requests and backup requests. The data registration unit 504 differs from the data registration unit 104 in FIG. 2 at least in the following points.

The data registration unit 504 receives an initial setting request from the initial setting request acquisition unit 501. The data registration unit 504 searches the database constructed in the backup data storage unit 506 for backup data associated with the link source identification data included in the initial setting request. Then, the data registration unit 504 associates the link destination identification data included in the initial setting request with this backup data and registers it in the database (that is, registers it in the backup data storage unit 506).

Specifically, the backup data storage unit 506 may store a backup data table (DB) including entries e31, e32, e33, . . . as illustrated in FIG. 11. Here, it is assumed that the initial setting request includes id_b1 as link source identification data and id_b2 as link destination identification data. In this case, the data registration unit 504 searches this backup data table for backup_B, which is backup data associated with id_b1 as the link source identification data. Then, the data registration unit 504 copies this backup data, associates id_b2 as link destination identification data with it, and registers it as a new entry in the table. Thereby, it becomes possible to search and restore the backup data (backup_B) of the water supply device 300 identified by id_b1 as the link source identification data based on id_b2 as the link destination identification data.

Note that if the link source identification data and the corresponding backup data (entry e32 in the example of FIG. 11) are unnecessary after the initial settings (link settings) are completed, the data deletion unit 509 described later deletes this entry as backup data. It may be deleted from the storage unit 506. Thereby, it is possible to prevent the capacity of the backup data storage unit 506 from being compressed due to duplicate registration of backup data. For example, the data registration unit 504 may notify the data deletion unit 509 of the entry to be deleted after the initial setting is completed.

The backup data storage unit 506 stores identification data in association with backup data. For example, backup data storage 506 may store identification data and backup data in a table format. This table can also be called a database. Backup data storage 506 may correspond to the memory and/or auxiliary storage described above.

The backup data storage unit 506 can have identification data and backup data written therein by the data registration unit 504 . Further, the identification data and backup data stored in the backup data storage unit 506 can be deleted by the data deletion unit 509. Further, the data stored in the backup data storage unit 506 can be read (including searching) by the data registration unit 504 and the data search unit 507.

The data search unit 507 may correspond to the processor described above. The data search unit 507 searches for backup data associated with identification data from the database constructed in the backup data storage unit 506 in response to various requests, such as search requests. The data search unit 507 differs from the data search unit 107 in FIG. 2 at least in the following points.

The data search unit 507 receives a search request from the search request acquisition unit 503. The data search unit 507 searches the database built in the backup data storage unit 506 for backup data associated with the identification data included in the search request.

The data deletion unit 509 may correspond to the processor described above. When the data deletion unit 509 is notified of the entry to be deleted (identification data and corresponding backup data) from the data registration unit 504, it deletes this entry from the backup data storage unit 506. Note that the data deletion unit 509 may issue an initialization completion notification and send it to the request response unit 508 instead of the data registration unit 504 .

As explained above, the backup system according to the second embodiment has a database that associates identification data of a device with backup data of the device. Then, when the backup server obtains an initial setting request that includes identification data of multiple different devices to be linked, it associates the link destination identification data with the backup data associated with the link source identification data in this database. and register it in the database. Therefore, according to this backup system, for example, the backup data associated with the identification data of the device before replacement is also associated with the identification data of the device after replacement. It becomes possible to restore the backup data of the previous device. That is, the backup data of a device can be automatically taken over and managed even after the device or its parts are replaced.

The embodiments described above merely show specific examples to help understand the concept of the present invention, and are not intended to limit the scope of the present invention. Various components can be added, deleted, or converted to the embodiments without departing from the gist of the present invention.

For example, multiple functional units described as being implemented in one device may be implemented across multiple separate devices, and conversely, multiple functional units described as being implemented across multiple separate devices may be implemented across multiple separate devices. It is also possible that the functional units described above are implemented in one device.

The various functional units described in each of the above embodiments may be implemented using circuits. The circuit may be a dedicated circuit that implements a specific function, or may be a general-purpose circuit such as a processor.

At least part of the processing in each of the embodiments described above can also be realized by using, for example, a processor installed in a general-purpose computer as the basic hardware. A program that implements the above processing may be provided while being stored in a computer-readable recording medium. The program is stored on a recording medium as an installable file or an executable file.

The recording medium may be any medium as long as it can store the program and is readable by a computer. Further, a program for realizing the above processing may be stored on a computer (server) connected to a network such as the Internet, and may be downloaded to a computer (client) via the network.
