Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional drying detection system, since a weight sensor is provided on the clothes drying pole, when drying laundry on a clothes drying pole without the weight sensor attached, the drying of the laundry cannot be detected. Therefore, in the conventional drying detection system, the situation where the drying of the laundry can be detected is limited, and there is room for further improving the convenience for the user.

[0005] Therefore, an object of the present invention is to improve the convenience for the user when detecting the drying of an article.

Means for Solving the Problems

[0006] One aspect of the present invention includes a wireless tag for detecting the drying of an article, a drying tool for drying the article, an information processing device, and a user terminal that can communicate with the information processing device and is held by a user of the drying tool. The user terminal has a request unit that can receive a transmission signal transmitted by the wireless tag provided in the drying tool and make a processing request to the information processing device, and a display control unit that causes a display unit to display information related to drying acquired from the information processing device. The information processing device has a determination unit that determines whether or not the article has dried in response to the processing request, and a notification unit that notifies the user terminal of the information related to drying based on the determination result by the determination unit. The wireless tag includes a first wireless tag attached at a position where the article does not come into contact, and a second wireless tag attached at a position where the article comes into contact. It is an information processing system.

Mode for Carrying Out the Invention

[0009] In the present disclosure, the "wireless tag" is, for example, an electronic tag attached to a drying tool. The wireless tag only needs to be configured such that information stored therein can be read wirelessly from an external communication device, and the tag may or may not be provided with a battery inside. The communication protocol and communication range between the wireless tag and the external communication device are not limited and can be appropriately changed or adjusted according to the application. In the present disclosure, the "drying tool" is, for example, a hanger, a fixture such as a washing clip, a tentacle hanger (also called a parasol hanger), a drying pole, etc., for attaching and drying articles such as clothes. In one embodiment, the article is clothing containing moisture, and the drying tool is a hanger. In the present disclosure, "capable of communication" is not limited to the case where communication is directly possible, but also includes the case where communication is indirectly possible. For example, "Device A and Device C are capable of communication" does not only refer to the case where Device A and Device C directly establish communication to transmit or receive data, but also includes the case where Device A and Device C transmit or receive data via Device B.

[0010] Hereinafter, a washing and drying system 1 which is an embodiment of an information processing system will be described with reference to the drawings. In the washing and drying system 1, the user can receive a service through the user terminal 2 that notifies when the laundry is dry. As shown in FIG. 1, the washing and drying system 1 includes a user terminal 2, an application server 5, and a tag management server 7. The application server 5 and the tag management server 7 constitute exemplary information processing devices. As shown in FIG. 1, in the washing and drying system 1 of one embodiment, the user terminal 2 is configured to be communicable with the application server 5 via the network NW.

[0011] The user terminal 2 is an information processing terminal possessed by the user, and is, for example, a portable terminal such as a tablet terminal or a smartphone, or a fixed terminal such as a desktop computer device, a gateway device, or a smart speaker. In one embodiment, an application program (hereinafter, appropriately referred to as the “dryness notification application”) for notifying that the laundry is dry is installed in the user terminal 2. In that case, when the dryness notification application is activated, the user terminal 2 is configured to start wireless communication with surrounding wireless tags and acquire the information of the wireless tags.

[0012] The hanger 6 is an example of a drying tool for hanging and drying laundry, for example. IoT tags T1 and T2 (examples of the first wireless tag and the second wireless tag, respectively) are attached to the hanger 6. The IoT tag (hereinafter, appropriately simply referred to as the “tag”) is an example of a wireless tag, but is an environment-powered device that obtains energy from the radio waves in the surrounding environment and does not have a battery. The tag can operate semi-permanently without a battery and is suitable for long-term use. In the following description, when referring to common matters regarding the IoT tags T1 and T2, they may be referred to as the tag or the tag T.

[0013] The tag is configured to perform low-power wireless communication. Examples of communication protocols include Bluetooth (R) Low Energy (hereinafter referred to as BLE), Bluetooth (R), ZigBee (R), etc. Hereinafter, the case of performing communication by BLE will be described as an example. When the tag complies with the BLE standard, it performs broadcast communication. Specifically, tags T1 and T2 periodically broadcast an advertising packet (described later; hereinafter simply referred to as "packet"), and the user terminal 2 receives the packet. In this broadcast communication, only one-way data transmission from tags T1 and T2 to the user terminal 2 is possible.

[0014] The packet transmitted from each tag contains a tag ID, which is identification information unique to the tag. In the present disclosure, when the user terminal 2 receives a packet containing a predetermined tag ID and the application server 5 acquires the tag ID via the user terminal 2, it means that the system has detected the tag corresponding to the tag ID. In one embodiment, the packet transmitted from each tag contains sensor data detected by the tag, but it is not essential to include the sensor data.

[0015] In one embodiment, as shown in FIG. 1, the user terminal 2 held by the user performs wireless communication with the tag and notifies the application server 5 of the information acquired from the tag via the network NW. However, it is not limited thereto. When there is a network device such as a wireless router in the house, the information of the tag may be configured to be notified to the application server 5 via the network device. The network NW is a LAN (Local Area Network), a mobile communication network, the Internet, etc., or a combination thereof.

[0016] FIG. 2 shows an exemplary hanger 6A in a state without laundry and a state with laundry. The hanger 6A is suitable for drying laundry such as towels. In the hanger 6A, the tag T1 is attached at a position where the laundry does not come into contact when the laundry is hung, and the tag T2 is attached at a position where the laundry comes into contact when the laundry is hung. Since the tag is a small and lightweight thin-film member, it can be easily attached to the hanger body with, for example, an adhesive or the like.

[0017] Fig. 3 shows a state without laundry and a state with laundry for an exemplary hanger 6B. The hanger 6B is suitable for drying laundry such as shirts. Also for the hanger 6B, similar to the hanger 6A, the tag T1 is attached at a position where the laundry does not come into contact when the laundry is hung, and the tag T2 is attached at a position where the laundry comes into contact when the laundry is hung.

[0018] The application server 5 is a network server that provides a drying notification service for notifying the user of the determination result of the drying of the laundry, and can communicate with the drying notification application of the user terminal 2 via the network NW. In a non-limiting example, the communication between the application server 5 and the drying notification application of the user terminal 2 is performed by HTTP, HTTPS, or the like. The drying notification application sequentially transmits the tag ID received from the tag T1 and the information on the detection presence or absence of the tag T2 (if detected, the tag ID of the tag T2) to the application server 5.

[0019] The tag management server 7 is a server that manages the tags attached to each hanger 6 used by the user, and can communicate with the application server 5 via the network NW. Upon receiving a processing request from the application server 5, the tag management server 7 determines whether the laundry hung on each hanger 6 held by each user is dry or not based on the information on whether each of the tags T1 and T2 is detected and the information such as the tag ID when the tag is detected, and returns the determination result to the application server 5. The application server 5 notifies the drying notification application of the user terminal 2 of the determination result obtained from the tag management server 7.

[0020] In the following description, the information on whether each of the tags T1 and T2 is detected and the information such as the tag ID when the tag is detected are collectively referred to as "tag detection information" as appropriate.

[0021] Next, a method for determining the drying of laundry by the tags T1 and T2 attached to the hanger 6 will be described. As described above, when each tag is operating normally, it periodically transmits a packet including the tag ID. However, when the laundry is wet, the tag T2 in contact with the laundry cannot transmit a packet normally from the antenna due to the moisture contained in the laundry. As time passes and the laundry dries, since the antenna operates normally, the tag T2 can transmit a packet. On the other hand, the tag T1 not in contact with the laundry can always transmit a packet normally from the antenna regardless of whether the laundry is dry or not. Therefore, based on the tag ID received from the tag T1 and the detection status of the tag T2, it is possible to determine whether the laundry hung on the hanger 6 is dry or not.

[0022] In order to reliably determine whether the laundry is dry or not, it is not sufficient to only detect the tag T2 once, and it is preferable to make a judgment based on the reception status such as the number of received packets and the reception frequency from the tag T2. For example, when the application server 5 detects the tag T2 more than a predetermined number of times via the drying notification application of the user terminal 2 within a predetermined time (such as 10 minutes), it determines that the corresponding laundry has dried. Further, when the state of detecting the tag T2 more than a predetermined number of times within a predetermined time (such as 30 seconds) continues for a predetermined number of times, the application server 5 determines that the corresponding laundry has dried.

[0023] Hereinafter, with reference to FIGS. 4 to 7, the configuration of each device of the washing and drying system 1 of the present embodiment will be described. FIG. 4 is a block diagram showing the internal configuration of each device of the washing and drying system 1 of the present embodiment. FIG. 5 is a diagram showing the configuration of an advertising packet transmitted from the tag T.

[0024] Referring to FIG. 4, the tag T includes a control unit 11, an antenna 12, a harvesting unit 13, a voltage control unit 14, an RF transceiver 15, and a sensor 16. Although the overall form of the tag T is not shown, for example, it is a thin-film member including a conductive metal foil in a predetermined pattern formed by the antenna 12 and the sensor 16, and an IC chip connected to the metal foil. The control unit 11, the harvesting unit 13, the voltage control unit 14, and the RF transceiver 15 are mounted in the IC chip.

[0025] The control unit 11 has a microprocessor and a memory 111, and controls the entire IoT tag T. The memory 111 is a RAM (Random Access Memory) or a ROM (Read Only Memory), and stores, in addition to the program executed by the microprocessor, the tag ID which is identification information unique to the tag T and the sensor data output by the sensor 16.

[0026] The harvesting unit 13 generates environmental power based on radio waves in the surrounding environment (for example, radio waves from surrounding wireless communications), and stores the power obtained by the power generation in the internal energy storage 131. In one embodiment, the harvesting unit 13 converts, for example, the wireless signal received by the antenna 12 into a DC voltage and stores it in the energy storage 131. The energy storage 131 is, for example, a capacitor. In the case of a capacitor, it may be configured on a semiconductor chip (that is, an on-die type capacitor).

[0027] The radio waves used by the harvesting unit 13 for environmental power generation can be radio waves in a wide range of multiple different frequency bands. In one embodiment, the tag T operates by obtaining energy from radio waves of one or more specific frequencies included in the surroundings. The specific frequency includes any radio wave frequency that can be converted into energy in the tag T. The specific frequency may include one or more frequency bands, or may be a specific frequency assigned from within the frequency band. In one embodiment, the specific frequency may be, for example, a specific frequency or frequency band standardized by a wireless communication standard or the like, or a specific frequency or frequency band specified by the operator providing the drying notification application according to this embodiment. Non-limiting examples of the radio waves used by the harvesting unit 13 for environmental power generation include radio waves from wireless communications in frequency bands adopted in mobile communication systems such as so-called 3G to 5G, radio waves from wireless communications in frequency bands adopted in communication standards such as Bluetooth (registered trademark) and Wi-Fi (registered trademark), radio waves from wireless communications in the 2.4 GHz band represented by communication protocols such as ZigBee (registered trademark) and Thread, radio waves from wireless communications in the frequency bands adopted in RFID (for example, the 900 MHz band and the 13.56 MHz band), and the like. The radio waves exemplified here are generally applicable in almost all households. The tag T operates on the power obtained by environmental power generation by the harvesting unit 13 based on the radio waves in the surrounding environment. Therefore, it is not necessary to mount a battery on the tag T, and the system cost can be suppressed. In addition, since there is no need to mount a battery, there is no need to perform battery replacement work, so there is no problem that the tag ID cannot be obtained even though the tag exists.

[0028] The voltage control unit 14 supplies an operating voltage to the control unit 11 and the RF transceiver 15, monitors the voltage of the energy storage 131, and switches the power mode according to the monitoring result. When the voltage of the energy storage 131 is below a predetermined threshold, the power mode is set to the first mode in which only the minimum circuit operates. At this time, in the control unit 11 and the RF transceiver 15, generation of packets and transmission of radio signals described later are not performed. When the voltage of the energy storage 131 is charged to a predetermined threshold or more, the power mode is set to the second mode in which a normal processing routine is executed. At this time, in the control unit 11 and the RF transceiver 15, various processes including packet generation and radio signal transmission are performed.

[0029] Note that even when the power mode is the first mode, for example, when the voltage of the energy storage 131 is charged to a predetermined threshold or more, the control unit 11 may store the sensor data detected by the sensor 16 together with the data at the detection time in the memory 111. In that case, when the power mode is switched from the first mode to the second mode, the control unit 11 may generate and transmit a packet including the sensor data and the data at the detection time stored in the memory 111. Thereby, the information of the tag during the period when the charging voltage of the energy storage 131 is relatively low can be provided to the application server 5 via the user terminal 2.

[0030] The sensor 16 is, for example, a temperature sensor. The temperature sensor can be mounted on an IC chip.

[0031] When the power mode is the second mode, the control unit 11 generates an advertising packet according to the BLE protocol. An advertising packet is a packet that is transmitted using an advertising channel to realize broadcast communication in BLE, and has the packet configuration shown in FIG. 5. Hereinafter, the advertising packet is simply referred to as a "packet" as appropriate.

[0032] In FIG. 5, the preamble and the address access are each a predetermined fixed value. The CRC is a cyclic redundancy check code, and is check data calculated using a predetermined generating polynomial for the packet payload (that is, the advertising channel PDU (protocol data unit)). The advertising channel PDU (hereinafter simply referred to as "PDU") consists of a header and a payload, and the payload consists of an ADV address and ADV data. The ADV address is the address of the advertiser (that is, the IoT tag T that is the entity to notify), but may be a random value set each time of transmission so as not to identify the transmission source. The ADV data is the data of the advertiser (broadcast data), and in one embodiment, includes the tag ID and the sensor data output by the sensor 16.

[0033] It is preferable that the control unit 11 encrypts the PDU. The encryption method is not limited, but for example, AES (Advanced Encryption Standard) with a key length of 128 bits can be used.

[0034] The RF transceiver 15 performs predetermined digital modulation (for example, GFSK (Gaussian Frequency Shift Keying)) on the packet (baseband signal) to be transmitted, and then performs quadrature modulation, and sends a high-frequency signal (in the case of BLE, a signal in the 2.4 GHz frequency band) to the antenna 12.

[0035] The antenna 12 includes a transmitting antenna and a power generation antenna. The transmission antenna transmits a high-frequency radio signal (packet) transmitted by the RF transceiver 15. On the other hand, the power generation antenna receives, for example, radio waves in the surrounding environment and functions as a rectenna in cooperation with the harvesting unit 13.

[0036] As shown in FIG. 4, the user terminal 2 includes a control unit 21, a storage 22, an operation input unit 23, a display unit 24, a first communication unit 25, and a second communication unit 26. The control unit 21 is mainly composed of a microprocessor and controls the entire user terminal 2. For example, the control unit 21 controls the first communication unit 25 to communicate with the tag by executing a drying notification application, and when a packet is received from the tag, it transmits the tag ID included in the packet to the application server 5.

[0037] Also, the control unit 21 acquires information on whether the laundry is dry from the application server 5 by executing a drying notification application and displays it on the display unit 24. The storage 22 is a storage device such as an SSD (Solid State Drive), and stores the execution results of the drying notification application and data (for example, authentication data) required for the execution of the drying notification application.

[0038] The control unit 21 functions as the following (i) request unit and (ii) display control unit by executing a drying notification application. (i) A request unit that, when receiving a packet (an example of a transmission signal) transmitted by the tag T1 and / or the tag T2 attached to the hanger 6, makes a processing request including tag detection information to the application server 5 (ii) A display control unit that causes the display unit 24 to display information on whether the laundry is dry (an example of information related to drying) acquired from the application server 5

[0039] The operation input unit 23 is an input interface that receives operation inputs from a store clerk to execute various programs, and may be a touch panel input unit provided on the display panel of the display unit 24. The display unit 24 includes, for example, a display panel such as an LCD (Liquid Crystal Panel) and a drive circuit for the display panel, and displays the execution result of the drying notification application. The first communication unit 25 performs wireless communication with an object within a communication range narrower than that of the second communication unit 26, for example, and is configured to receive packets transmitted from each tag according to the BLE protocol. The second communication unit 26 is a communication interface for communicating with the application server 5. The communication protocol is not limited, but for example, it is HTTP, HTTPS, or the like.

[0040] As shown in FIG. 4, the application server 5 includes a control unit 51, a storage 52, and a communication unit 53. The control unit 51 is mainly composed of a microprocessor and controls the entire application server 5. By executing a server program by the microprocessor, a drying notification service that notifies the drying notification application of the user terminal 2 of the determination result as to whether the laundry is dried is provided to the user.

[0041] The storage 52 includes, for example, a large-capacity storage device such as an HDD (Hard Disk Drive) and stores a member database. FIG. 6 shows an example of the data configuration of the member database. The member database shown in FIG. 6 is a database that includes values of each field such as "member code", "name", "gender", and "address" for one record. The fields of "name", "gender", and "address" are merely examples and can be changed as appropriate. Note that the member code may be set on a family basis. For the member code set on a family basis (family member code), for example, a plurality of names, genders, addresses, etc. of the family members are associated. Also, when associating the terminal information of the user terminal corresponding to the member code in the member database, for the family member code, a plurality of terminal information corresponding to each person constituting the family may be associated, or the terminal information of the representative designated within the family may be associated, or the terminal information of a family common terminal such as a smart speaker may be associated. Regarding the determination result of the drying determination described later, it is notified based on the terminal information associated with the family member code. The server program identifies the member code and establishes a session with the drying notification application.

[0042] The communication unit 53 functions as a communication interface for communicating with the user terminal 2. By executing the server program, the control unit 51 functions as a notification unit that notifies the user terminal 2 of information on whether the laundry is dry based on the determination result of the drying of the laundry by the tag management server 7.

[0043] As shown in FIG. 4, the tag management server 7 includes a control unit 71, a storage 72, and a communication unit 73. The control unit 71 is mainly composed of a microprocessor and controls the entire tag management server 7. For example, in the control unit 71, the microprocessor executes the server program to determine whether the laundry is dry in response to a processing request from the application server 5, and is configured to return the determination result to the application server 5. Note that the processing request from the application server 5 includes tag detection information. That is, by executing the server program, the control unit 71 functions as a determination unit that determines whether the laundry is dry based on the packet received by the user terminal 2 in response to the processing request from the application server 5. The method for determining the drying of the laundry is as described above.

[0044] The storage 72 is a storage device such as an HDD and stores a tag database. The tag database is a database for enabling the server program to recognize who the user of the hanger 6 corresponding to the tag ID acquired from the user terminal 2 is. Fig. 7 shows an example of the data configuration of the tag database. As shown in Fig. 7, in the tag database, at least the tag ID of the tag and the user of the hanger 6 to which the tag is attached are associated. The user of the hanger 6 corresponds to any one of the member codes included in the member database. In addition to the tag ID and the user shown in Fig. 7, the tag database shown in Fig. 7 includes the values of each field such as "Owner", "Place of origin", "Date of birth", "Group name", "Lifespan", etc., and each value is pre-input, for example, by an operator providing a drying notification application or a hanger manufacturer. In one embodiment, the value of the "User" field is appropriately rewritten according to the change of the user of the hanger 6. In the tag database, the information including the value of each field for each tag ID is referred to as "tag information".

[0045] Next, with reference to Fig. 8, the operation of the washing and drying system 1 will be described. Fig. 8 is a sequence chart showing the operation of the washing and drying system 1. Note that in Fig. 8, it is assumed that a session is established between the drying notification application of the user terminal 2 and the application server 5, and the application server 5 recognizes the member code corresponding to the drying notification application.

[0046] At the user's home, for example, based on the radio waves transmitted by a network device such as a wireless LAN installed at home, the tags T1 and T2 attached to the hanger 6 perform environmental power generation and broadcast packets. This packet is an advertising packet broadcast. When the drying notification application of the user terminal 2 recognizes and receives the packets transmitted from each tag (step S2), it transmits a processing request including tag detection information to the application server 5 (step S4). The transmission of the processing request from the user terminal 2 is repeated. In this case, the first transmission of the processing request may be performed based on a predetermined operation immediately after the user dries the laundry, or may be performed automatically. In the latter case, for example, when the drying notification application of the user terminal 2 changes from a state of receiving packets from tags T1 and T2 to a state of receiving only the packets from tag T1, it is determined that the laundry has been dried, and the drying notification application of the user terminal 2 starts transmitting the processing request. As described above, the tag detection information is information on whether each of the tags T1 and T2 has been detected, and information on the tag ID when the tag has been detected.

[0047] The application server 5 associates the processing request received in step S4 with the member code of the drying notification application that is the request source, and transmits it to the tag management server 7 (step S6). The tag management server 7 performs a drying determination based on the tag detection information included in the received processing request (step S8), and returns the determination result to the application server 5 in association with the member code (step S10). The determination result is "dried", "not dried", "about to dry soon", "degree of dryness", "scheduled drying time", etc.

[0048] As illustrated in FIGS. 2 and 3, even when the laundry containing moisture is hung on the hanger 6, since the tag T1 does not come into contact with the laundry, it can be detected as long as it is not malfunctioning. Therefore, when the tag ID of the tag T1 is included in the tag detection information, it can be known that the user of the target member code is using the hanger 6. Also, when the user is using a plurality of hangers 6, it can be known which hanger 6 is being used based on the tag ID of the tag T1.

[0049] On the other hand, since the tag T2 is attached at a position where it comes into contact with the laundry when the laundry is hung on the hanger 6, if the laundry contains moisture, the packet cannot be transmitted appropriately. Therefore, based on whether the tag T2 is detected or not, it is possible to determine whether the laundry hung on the hanger 6 to which the tag T1 is attached is dry. This determination is preferably made based on the tag detection information included in a plurality of processing requests, rather than the tag detection information included in a single processing request. That is, as described above, it is preferable to make a determination based on the reception status such as the number of receptions and reception frequency of the tag ID included in the packet from the tag T2. In that case, even if the tag ID of the tag T2 can be received based on a single processing request, the determination result shall be "not dry" until the reception result of the tag ID of the tag T2 based on a predetermined number of processing requests is obtained.

[0050] The application server 5 returns the determination result of the drying of the laundry to the drying notification application for the target member code (step S12). The drying notification application causes the determination result to be displayed on the display unit 24 of the user terminal 2 (step S14). Thereby, the user can timely recognize, for example, whether the laundry hung outdoors is dry and can be taken indoors, even when indoors. Note that the application server 5 returns the determination result to the user terminal 2 that is the transmission source of the processing request in step S4 in step S12, but it is not limited to that. For example, when a smart speaker is registered in the member database as a terminal commonly used by the family, the determination result may be returned to the smart speaker. Also, in the member database, when terminal information of a plurality of user terminals 2 is set for the family member code, or when terminal information of a plurality of user terminals 2 is set for the member code, the determination result may be returned to the user terminal 2 located closest to the registered address. In that case, the plurality of user terminals 2 sequentially notify the application server 5 of the location information (for example, GPS information), and the application server 5 identifies the user terminal 2 closest to the registered address among the plurality of user terminals 2.

[0051] As described above, in the washing and drying system 1 of one embodiment, based on the tag detection information obtained from the tag attached to the hanger, the determination result as to whether the laundry hung on the hanger is dried can be displayed on the user terminal of the user. In this system, it is only necessary to attach a small tag to the hanger, and a weight sensor or the like is not required as in the conventional system, so the versatility is high. Therefore, the convenience of the user when detecting the drying of the laundry can be improved. Also, for the operator providing the drying notification service, it becomes possible to grasp the actual situation of the user's laundry and utilize it for marketing and product development.

[0052] In the above description, the case where the user uses one hanger has been described, but it is not limited to that. When the user uses a plurality of hangers, since each hanger is attached with a tag corresponding to a unique tag ID, it is possible to determine the drying of the laundry for each hanger. At that time, by assigning numbers to the plurality of hangers and associating the number assigned to each hanger with the tag ID of the tag T1 attached to each hanger in the tag information, it is possible to configure to display the determination result of drying for each hanger number on the drying notification application. For example, among the plurality of hangers 6 associated with the membership code, it is also possible to specify which hanger 6 is currently in use and what percentage (for example, 4 out of 10) of the laundry on the hangers 6 is dried (degree of dryness), etc., and notify the drying notification application of the user terminal 2.

[0053] In one embodiment, in order to improve the determination accuracy as to whether the laundry is dried, each tag may be provided with a sensor. When the tag is provided with a sensor, the packet transmitted from the tag includes the tag ID of the tag and the data detected by the sensor (sensor data).

[0054] In one embodiment, each of tags T1 and T2 has a temperature sensor for detecting the ambient temperature, and the temperature sensor detects the temperature at the position where each tag is attached. In this case, the packet transmitted from each tag includes sensor data, which is temperature information detected by the temperature sensor of each tag. In this case, the tag detection information included in the processing request sent from the user terminal 2 to the application server 5 and further to the tag management server 7 includes the temperature information detected by each tag. Then, the tag management server 7 determines whether the laundry is dry based on the temperature information detected by tag T2 or the difference between the temperature information detected by tag T1 and tag T2. For example, when tag T2 is detected and the temperature detected by tag T2 is higher than a predetermined value, it is determined that the laundry hung on the hanger 6 is dry. Also, when the laundry is wet, tag T2 in contact with the laundry may not be detected, or even if it is detected, its temperature is relatively lower than the temperature of tag T1. As the laundry dries, the temperature difference between tag T2 and tag T1 becomes smaller. Therefore, when the temperature difference between tag T2 and tag T1 is equal to or less than a predetermined value, it may be determined that the laundry hung on the hanger 6 is dry.

[0055] In one embodiment, each of tags T1 and T2 has a humidity sensor for detecting the ambient humidity, and the humidity sensor detects the humidity at the position where each tag is attached. The packet transmitted from each tag includes sensor data, which is humidity information detected by the humidity sensor of each tag. In this case, the tag detection information included in the processing request sent from the user terminal 2 to the application server 5 and further to the tag management server 7 includes the humidity information detected by each tag. Then, the tag management server 7 determines whether the laundry is dry based on the humidity information detected by tag T2 or the difference between the humidity information detected by tag T1 and tag T2. For example, when tag T2 is detected and the humidity detected by tag T2 is lower than a predetermined value, it is determined that the laundry hung on hanger 6 is dry. Also, when the laundry is wet, tag T2 that comes into contact with the laundry is not detected, or even if it is detected, its humidity is relatively higher than that of tag T1, and as the laundry dries, the humidity difference between tag T2 and tag T1 becomes smaller. Therefore, when the humidity difference between tag T2 and tag T1 is equal to or less than a predetermined value, it may be determined that the laundry hung on hanger 6 is dry.

[0056] In one embodiment, each of tags T1 and T2 has the temperature sensor and the humidity sensor described above, and the packet transmitted from each tag includes sensor data that is temperature information and humidity information respectively detected by the temperature sensor and humidity sensor of each tag. In this case, tag management server 7 determines whether the laundry is dry based on the temperature information and / or humidity information detected by each tag. When determining whether the laundry is dry based on temperature information and / or humidity information, the determination conditions may be changed according to the current season (for example, summer or winter), whether the laundry is dried indoors or outdoors, etc. For example, since the outside air temperature is different between summer and winter, it is preferable to change the threshold value for the temperature of tag T2. Note that tag management server 7 may predict the time when the laundry dries, etc., based on, for example, the temperature information or humidity information detected from tag T1, the time information when the temperature information or humidity information is detected, etc. Also, tag T1 may have a weight sensor, and tag management server 7 may predict the time when the laundry dries, etc., by combining, for example, the weight information, temperature information, humidity information, time information, etc. detected from tag T1.

[0057] In one embodiment, it may be determined whether the laundry is dry based on weather information corresponding to the location information such as the user's residence. By performing the dryness determination with reference to the weather information in addition to the tag detection information described above, the accuracy of the dryness determination can be improved. For example, for information such as different seasons, weather, wind direction and wind speed, external temperature and humidity information obtained from tag T1, or for each combination of these, the reception status such as the number of times or frequency of detecting tag T2, and the relationship between whether the laundry is dry, the degree of dryness of the laundry, the drying schedule, etc. are recorded in advance in a database. By referring to this database, a threshold value for the number of times or frequency of detecting tag T2 is set. Further, in the above database, the relationship between the combination of the material, size, weight, etc. of the laundry such as towels and shirts, the reception status such as the number of times or frequency of detecting tag T2, and whether the laundry is dry, the degree of dryness of the laundry, the drying schedule, etc. may also be recorded in advance. Then, by referring to the database, a threshold value for the number of times or frequency of detecting tag T2 is set. As a result, not only the determination result of simply "dry" or "not dry" but also "degree of dryness" and "drying scheduled time" can be included as the determination result. Also, since the accuracy of the drying determination is improved, for example, the possibility that the notification of drying is delayed more than necessary can be reduced. In this embodiment, the user terminal 2 has a position information acquisition unit that acquires the position information of the user terminal 2. The position information acquisition unit can be configured by, for example, a GPS (Global Positioning System) receiver. The drying notification application of the user terminal 2 notifies the application server 5 of the position information regularly or irregularly. The application server 5 has a weather information acquisition unit that acquires weather information corresponding to the position information acquired from the drying notification application of the user terminal 2. The weather information can be acquired, for example, as data distributed from a regional weather observation center. The tag management server 7 acquires from the application server 5 the tag ID included in the packet received by the user terminal 2 and the weather information acquired by the weather information acquisition unit, and determines whether the laundry is dry based on these pieces of information.

[0058] In one embodiment, based on weather information corresponding to the location information such as the user's residence, etc., it may be configured to predict the timing when the laundry dries and / or the timing to move the laundry indoors and notify the user. When the user knows the weather information of the place where the laundry is dried, for example, the environment such as the temperature and humidity of the place can be known, so the timing (scheduled drying time) when the laundry dries can be notified to the user by making a drying determination according to the environment. Also, if the timing when it starts to rain can be known from weather information such as the weather forecast of the place where the user dries the laundry, it is preferable to notify the user of the timing to move the laundry indoors.

[0059] In this embodiment, the user terminal 2 has a location information acquisition unit that acquires the location information of the user terminal 2. The drying notification application of the user terminal 2 notifies the location information to the application server 5 periodically or irregularly. The application server 5 has a weather information acquisition unit that acquires weather information corresponding to the location information acquired from the drying notification application of the user terminal 2. The application server 5 has a timing determination unit that determines the timing when the laundry dries and / or the timing to move the laundry indoors based on the tag ID included in the packet of tag T1 and / or tag T2 received by the user terminal 2 and the weather information acquired by the weather information acquisition unit. Note that this timing determination may be performed in cooperation with the application server 5 and the tag management server 7.

[0060] For example, regarding the timing when the laundry dries, for different outside air temperatures and weather conditions, the relationship between the frequency of detecting tag T2 and the drying time (the time from detecting the tag at a predetermined frequency until drying) may be recorded in a database in advance, and the timing may be predicted by referring to this database. For example, when a drying determination is made to determine that the laundry has dried when tag T2 is detected a predetermined number of times (N times) or more within a predetermined time (such as 10 minutes), the timing when the laundry dries is predicted as follows. Refer to the database at the timing when tag T2 is detected 1 / 3N times and 1 / 2N times within the above-mentioned predetermined time, and obtain the drying time of the laundry from this timing. This drying time may be corrected based on the outside air temperature and weather forecast, etc. based on meteorological information. Also, the timing to move the laundry indoors may be set to a predetermined time before the scheduled time when it is going to rain at the location of the user. The application server 5 notifies the drying notification application of the user terminal 2 of the timing determined by the timing determination unit.

[0061] Next, a washing and drying system according to another embodiment will be described with reference to FIGS. 9 to 11. FIG. 9 shows the system configuration of the washing and drying system of this embodiment. The washing and drying system shown in FIG. 9 includes a user terminal 2, an application server 5, and a tag management server 7, similar to FIG. 1, but is characterized in that the drying notification service provided to the user by the application server 5 is restricted. In FIG. 9, the detergent container 8 contains detergent A (an example of a consumable) for washing the user's clothes and the like. Detergent A may be liquid or powder. Code information C1, such as a two-dimensional code, is attached to the outer surface of the detergent container 8. The code information C1 is information unique to each individual detergent container 8.

[0062] The user terminal 2 of one embodiment is provided with an imaging function and a code reading function. When the drying notification application of the user terminal 2 reads the code information C1 according to the user's operation, it is configured to send a setting request to the application server 5 for receiving the drying notification service a predetermined number of times, for example, according to the usage amount of the detergent A. When it is desired to receive the drying notification service after receiving it a predetermined number of times, the user needs to perform an operation of reading the code information C1 attached to the detergent container 8 of another individual. That is, it is necessary to newly purchase a detergent container 8 and perform an operation of reading the code information C1 attached to the purchased detergent container 8.

[0063] FIG. 10 is a sequence chart showing the operation of the washing and drying system shown in FIG. 9. Hereinafter, with reference to FIG. 10, the operation of the washing and drying system of one embodiment will be described. In FIG. 10, when the user performs a predetermined operation, the drying notification application of the user terminal 2 reads the code information C1 (for example, a two-dimensional code) attached to the detergent container 8 (step S20), and sends a setting request including the code information C1 to the application server 5 (step S22). The application server 5 sends the setting request received in step S22 to the tag management server 7 in association with the member code of the drying notification application (step S24).

[0064] The tag management server 7 accesses the tag database (FIG. 7), and sets "0" as the usage times (referred to as "NUM") in the "lifetime" field value for all tag information whose "user" field value is the member code of the user to be processed. The usage times NUM is a value indicating the number of times the drying notification service has been received. By setting the usage times NUM to "0", the tag corresponding to the member code to be processed can be used a predetermined number of times, and thereby the drying notification service can be used a predetermined number of times.

[0065] Each time the drying notification service is received, the processing after step S32 is performed. Steps S32, S34, and S36, which are the processes after the user terminal 2 receives the packets transmitted from tag T1 and / or tag T2 attached to the hanger 6, are the same as steps S2, S4, and S6 in FIG. 8, respectively. That is, when the drying notification application of the user terminal 2 recognizes and receives the packets transmitted from each tag (step S32), it transmits a processing request including tag detection information to the application server 5 (step S34). As described above, the tag detection information is information on whether each of tags T1 and T2 is detected and the tag ID information when the tag is detected. The application server 5 associates the processing request received in step S34 with the member code of the drying notification application that is the request source and transmits it to the tag management server 7 (step S36).

[0066] When receiving the processing request, the tag management server 7 refers to the tag information in the tag database to determine whether the user corresponding to the member code can receive the drying notification service. Specifically, it refers to the value of the "lifetime" field of the tag information corresponding to the member code to determine whether the number of usage times NUM is less than or equal to a predetermined number of times TH (step S38). Here, the predetermined number of times TH is the number of times the drying notification service can be received by reading the code information C1 once, and can be arbitrarily set by the provider providing the drying notification service. Immediately after the number of usage times NUM is set, it is "0" in step S26, so the determination in step S38 is "YES", and the drying notification service can be received.

[0067] When the number of usage times NUM is less than or equal to the predetermined number of times TH, the tag management server 7 makes a drying determination based on the tag detection information included in the processing request received in step S36 (step S40) and returns the determination result to the application server 5 in association with the member code (step S42). The application server 5 returns the drying determination result of the laundry to the drying notification application for the target member code (step S44). The drying notification application causes the determination result to be displayed on the display unit 24 of the user terminal 2 (step S46).

[0068] When the tag management server 7 performs the drying determination in step S40 and the determination result is "dried" (step S48: YES), the tag database is updated so that the usage count NUM is incremented by one in the tag information corresponding to the target member code (step S50). That is, when the determination result is "dried", it means that the user of the target member code has received the drying notification service, so the usage count NUM is increased by 1. Therefore, each time the drying notification service is received, the usage count NUM increases by one, and when a predetermined number of times TH is reached, it becomes "NO" in step S38 and no further drying determination is performed. For this reason, the number of times the drying notification service can be received by reading the code information C1 once is limited to the predetermined number of times TH. Note that the transmission of the processing request in step S34 from the user terminal 2 is repeated. In that case, as described above, the first transmission of the processing request may be performed based on a predetermined operation immediately after the user dries the laundry, or may be performed automatically. In the latter case, for example, when the drying notification application of the user terminal 2 changes from a state of receiving packets from tags T1 and T2 to a state of receiving only packets from tag T1, it is determined that the laundry has been dried, and the drying notification application of the user terminal 2 starts transmitting the processing request. Also, based on the tag detection information, it may be determined that one service has ended when the drying notification application of the user terminal 2 changes from a state of receiving only packets from tag T1 to a state of receiving packets from tags T1 and T2. Alternatively, it may be determined that the service for the corresponding hanger 6 has been provided on the condition that a predetermined time (for example, 30 minutes) has elapsed since the first processing request was transmitted from the user terminal 2, and step S50 (increment the usage count NUM by one) may be executed.

[0069] In FIG. 10, the tag management server 7 determines whether the user of the target member code can receive the drying notification service, but this is not the only case. FIG. 11 shows an example in which the application server 5 determines whether the user of the target member code can receive the drying notification service.

[0070] In FIG. 11, when the user performs a predetermined operation, the drying notification application on the user terminal 2 reads the code information C1 (for example, a two-dimensional code) attached to the detergent container 8 (step S20), and transmits a setting request including the code information C1 to the application server 5 (step S22), which is the same as in FIG. 10. The application server 5 sets the usage count NUM to "0" (step S25), and associates the usage count NUM with the member code and records it in the storage 52.

[0071] When the drying notification application on the user terminal 2 recognizes and receives a packet transmitted from each tag (step S32), it transmits a processing request including the tag detection information to the application server 5 (step S34), which is the same as in FIG. 10. When the application server 5 receives the processing request, it refers to the usage count NUM recorded in the storage 52 and determines whether the user corresponding to the member code can receive the drying notification service. That is, it determines whether the usage count NUM is less than or equal to a predetermined number TH (step S35).

[0072] When the usage count NUM is less than or equal to the predetermined number TH, the application server 5 associates the processing request received in step S34 with the member code of the drying notification application that is the request source, and transmits it to the tag management server 7 (step S36). The tag management server 7 performs a drying determination based on the tag detection information included in the processing request received in step S36 (step S40), and returns the determination result associated with the member code to the application server 5 (step S42). The application server 5 returns the determination result of the drying of the laundry to the drying notification application for the target member code (step S44). The drying notification application causes the determination result to be displayed on the display unit 24 of the user terminal 2 (step S46).

[0073] When the determination result received in step S42 is "dried" (step S49: YES), the application server 5 updates the data of the usage count NUM stored in the storage 52 so that the usage count NUM corresponding to the target member code is incremented by one (step S51). As a result, the number of times the drying notification service can be received by reading the code information C1 once is limited to a predetermined number of times TH by the application server 5.

[0074] As described above, according to the washing and drying system of the embodiment shown in FIG. 9, by performing an operation of reading the code information C1 attached to the detergent container 8 containing the detergent used for washing clothes and the like, the user can receive the drying notification service only a predetermined number of times. That is, the number of times the drying notification service is provided is limited in association with the amount (usage amount) of the detergent contained in the detergent container 8. Therefore, in order to continuously receive the drying notification service, the user can be motivated to continue purchasing the detergent, and the detergent manufacturer can be promoted to sell the detergent. In addition, for the detergent manufacturer, the actual usage state of its own detergent can be grasped. Although the case where the user receives the drying notification service a predetermined number of times by performing the operation of reading the code information C1 has been described, it is not limited thereto. By performing the operation of reading the code information C1, the user may be able to receive the drying notification service for a predetermined number of days set according to the amount (usage amount) of the detergent. The restriction of the drying notification service is not limited to the restriction of the number of times or the number of days of providing the service. In one embodiment, the restriction of the drying notification service may be the restriction of the number of times or the number of days of providing the service that can be provided for free, or may be the restriction of the number of hangers 6 capable of drying detection provided to the user.

[0075] In one embodiment, when the remaining amount of detergent in the detergent container 8 is less than a predetermined amount, the application server 5 restricts the provision of the drying notification service to the user. Since the user cannot receive the drying notification service when the remaining amount of detergent decreases, the user is motivated to purchase a new detergent container 8. An example of a method for detecting the remaining amount of detergent in the detergent container 8 will be described with reference to FIGS. 12 and 13.

[0076] In the example of FIG. 12, a pump-type detergent container 8A is illustrated. As shown in FIG. 12, the detergent container 8A has a main body portion 81A and a lid portion 82A, and the main body portion 81A contains liquid detergent. The lid portion 82A has a tube 821 for sucking out the liquid detergent. One or more tags T11 to T14 (four tags in this example) are attached to the tube 821 along the depth direction of the liquid detergent in the main body portion 81A.

[0077] When the drying notification application of the user terminal 2 receives a packet from the tags T11 to T14, it notifies the application server 5 of the tag ID included in the packet. As shown in FIG. 12, when the remaining amount of liquid detergent is large, all of the tags T11 to T14 are immersed in the liquid detergent, so the antenna does not function and the packet cannot be transmitted. Therefore, since the application server 5 cannot obtain the tag ID from any of the tags via the drying notification application, it can be understood that the remaining amount of liquid detergent is large. As the liquid detergent decreases, some of the tags T11 to T14 are no longer immersed in the liquid detergent, so that the antenna becomes functional. Therefore, the application server 5 can estimate the approximate remaining amount of the liquid detergent based on the tag ID obtained via the drying notification application. As described above, the remaining amount of the liquid detergent can be estimated based on whether the tags T11 to T14 attached to the detergent container 8A are detected.

[0078] In the example of FIG. 13, an injection-type detergent container 8B is illustrated. As shown in FIG. 13, the detergent container 8B has a main body portion 81B and a lid portion 82B. The main body portion 81B contains liquid detergent or powder detergent. By turning the lid portion 82B, the lid portion 82B can be removed from the main body portion 81B, and the detergent can be taken out from the main body portion 81B. On the bottom surface of the main body portion 81B, a tag TS with a weight sensor is provided. The tag TS does not necessarily have to be configured integrally with the weight sensor, and the tag T shown in FIG. 4 and the weight sensor may be combined and configured. The tag TS transmits a packet including a tag ID and sensor data including the value of the weight detected by the weight sensor. The drying notification application of the user terminal 2 acquires the tag ID and sensor data from the packet transmitted from the tag TS, and sequentially notifies the application server 5. The application server 5 can grasp the remaining amount of the detergent in the detergent container 8B pre-associated with the tag ID based on the sensor data.

[0079] As exemplified above, when the application server 5 grasps the remaining amount of the detergent, if the remaining amount is compared with a predetermined amount and it is determined that the remaining amount is less than the predetermined amount, the provision of the drying notification service to the user is restricted. Thereby, the user can be motivated to continue purchasing the detergent in order to continue receiving the drying notification service. In addition, when the remaining amount of the detergent decreases, the application server 5 may send a message prompting the purchase of a new detergent to the target drying notification application. Thereby, it is possible to prevent the user from being unaware that the remaining amount of the detergent is decreasing and forgetting to purchase additional detergent.

[0080] The embodiments of the information processing apparatus, information processing system, information processing method, and program have been described above, but the present invention is not limited to the above embodiments. Also, various improvements and modifications are possible within the scope that does not deviate from the gist of the present invention.

[0081] For example, the case where an environment - powered IoT tag that obtains energy from the radio waves in the surrounding environment and operates as a wireless tag is applied was described. When an IoT tag is applied, unlike conventional passive tags, since it is powered by radio waves existing in the surrounding environment and operates, there is an advantage that it is not always necessary to fixedly arrange a reader - writer nearby for power supply. However, it is not necessary to apply an IoT tag. An apparatus in which a sensor is combined with an active - type RFID tag (active tag) with a built - in battery or a passive - type RFID tag (passive tag) without a built - in battery may be applied as a wireless tag. In that case, for example, a reader - writer is installed in the user's home, and the reader - writer reads the tag ID and sensor data stored in the RFID tag and notifies an application server.

[0082] Also, a BLE tag may be applied as a wireless tag. A BLE tag performs BLE communication in the same way as the above - mentioned IoT tag, but is different from the IoT tag in that it has a built - in battery. A sensor can also be built into the BLE tag. In the case of a BLE tag as well, similar to the IoT tag, it is possible to broadcast radio waves including the tag ID and, if necessary, sensor data, and for the user terminal 2 to receive the radio waves and perform the above - described processing.

[0083] In the above - described embodiment, the case of attaching two tags to a hanger was described, but it is not limited to this. For example, if the hanger used by the user to dry laundry is known based on an operation input on a drying notification application by the user, it is possible to notify the drying determination result based on the tag detection information of tag T2 attached at a position in contact with the laundry while the laundry is hung on hanger 6. In one embodiment, for tag T1 attached to the central hanging part, like an octopus - leg hanger, a plurality of tags T2 attached to each radially - spreading hanger body part may be linked, and the degree of dryness, such as how many towels are dry, may be determined.

[0084] In the above-described embodiment, the drying notification application may be configured so that a part of the functions of the application server 5 and the tag management server 7 are realized by the user terminal 2. That is, a part of the functions of the application server 5 and the tag management server 7 can also be realized as a native application. Further, a part of the functions of the application server 5 may be realized by the tag management server 7, or a part of the functions of the tag management server 7 may be realized by the application server 5.
