[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In all drawings describing the embodiments, common components are designated by the same reference numerals, and repeated description will be omitted. Note that the following embodiments do not unduly limit the content of the present disclosure described in the claims. Furthermore, not all components shown in the embodiments are necessarily essential components of the present disclosure. Furthermore, each drawing is a schematic diagram and is not necessarily a precise illustration.

[0011] <Overview> A WPT (Wireless Power Transfer) system includes one or more transmitters that transmit power feed signals and multiple receivers that receive the power feed signals. One or more measuring devices measure the electric field strength based on the power feed signals transmitted by the transmitters. An information processing device calculates the electric field strength distribution in a measurement target space (indoor space) based on the electric field strength measured by the measuring devices.

[0012] <1 Overall System Configuration> FIG. 1 is a diagram showing the overall configuration of a WPT system 1 according to this embodiment.

[0013] The WPT system 1 shown in Fig. 1 includes, for example, a transmitter 100, a receiver 200, a first information processing device 300, a second information processing device 400, and a measuring device 500. The WPT system 1 shown in Fig. 1 is used, for example, in a building, a factory, or the like. A building is an example of a structure, and the WPT system is not limited to a building as long as it is an indoor space where predetermined activities such as business and office work are carried out. The connection between the transmitter 100 and the first information processing device 300, and the connection between the first information processing device 300 and the second information processing device 400 may be wired or wireless.

[0014] 1 shows an example in which the WPT system 1 includes three transmitters 100, but the number of transmitters 100 included in the WPT system 1 is not limited to three. The number of transmitters 100 included in the WPT system 1 may be two or less, or may be four or more.

[0015] 1 shows an example in which the WPT system 1 includes seven receivers 200, but the number of receivers 200 included in the WPT system 1 is not limited to seven. The number of receivers 200 included in the WPT system 1 may be six or less, or eight or more.

[0016] In this specification, the transmitter 100 is a (power) transmitter 100 in the sense of wirelessly transmitting power, and similarly, the receiver 200 is a (power) receiver 200 in the sense of wirelessly receiving power. As will be described later, the receiver 200 may transmit, for example, information about the state of the receiver 200 or information about measurement results by a sensor to the transmitter 100 as a data signal, and the transmitter 100 may receive such a data signal. In this case, the transmitter 100 is a receiver that receives the data signal, and the receiver 200 functions as a transmitter that transmits the data signal.

[0017] 1 shows an example in which the WPT system 1 includes two measuring devices 500, but the number of measuring devices 500 included in the WPT system 1 is not limited to two. The WPT system 1 may include one measuring device 500, or three or more measuring devices 500. The measuring device 500 is provided, for example, so as to be movable within a space in which the WPT system 1 is used.

[0018] 1 shows an example in which the WPT system 1 includes two first information processing devices 300, but the number of first information processing devices 300 included in the WPT system 1 is not limited to two. The number of first information processing devices 300 included in the WPT system 1 may be one, or three or more.

[0019] The transmitter 100 transmits, for example, a power supply signal or a data signal to the receiver 200. The transmitter 100 transmits the power supply signal to the receiver 200 by radio waves in the 920 MHz band, for example. The transmitter 100 transmits the data signal to the receiver 200 by radio waves in the 2.4 GHz band, for example. The transmitter 100 may transmit the data signal by radio waves in the 920 MHz band.

[0020] The transmitter 100 may, for example, supply power to one receiver 200, or may supply power to multiple receivers 200. The transmitter 100 may, for example, transmit a data signal to one receiver 200, or may transmit a data signal to multiple receivers 200. The transmitter 100 may, for example, transmit the same data signal as another transmitter 100, or may transmit a data signal different from that of the other transmitters 100. The transmitter 100 may, for example, transmit a predetermined command signal as a data signal to the receiver 200, or may transmit a preset signal as a data signal to the receiver 200.

[0021] The transmitter 100 receives, for example, a data signal transmitted from the receiver 200. The transmitter 100 may receive, for example, a data signal transmitted from one receiver 200, or may receive data signals transmitted from a plurality of receivers 200. The transmitter 100 transmits the data signal transmitted from the receiver 200 to the first information processing device 300. The transmitter 100 transmits information related to the state of the transmitter 100 to the first information processing device 300.

[0022] The receiver 200 receives, for example, a power supply signal or a data signal transmitted from the transmitter 100. If the receiver 200 has, for example, a power storage unit, it converts the power supply signal transmitted from the transmitter 100 into power and stores the converted power in the power storage unit. If the receiver 200 has, for example, a predetermined sensor, it converts the power supply signal transmitted from the transmitter 100 into power and drives the sensor with the converted power. The receiver 200 may drive the sensor with the power stored in the power storage unit.

[0023] The receiver 200 transmits, for example, information about the state of the receiver 200 or information about the measurement results of the sensor to the transmitter 100 as a data signal.

[0024] The measuring device 500 measures, for example, the strength of the electric field (electric field strength) generated by the power supply signal transmitted from the transmitter 100. The measuring device 500 measures, for example, the strength along three axes in a Cartesian coordinate system of the electric field generated by radio waves in the 920 MHz band transmitted from the transmitter 100. The measuring device 500 performs, for example, predetermined statistical processing on the measured electric field strength. The measuring device 500 transmits the processed information to the first information processing device 300, for example, by radio waves in the 2.4 GHz band.

[0025] Furthermore, the measuring device 500 measures its own position within the space in which the WPT system 1 is used, for example. The measuring device 500 measures, for example, the position (coordinates) along three axes in a Cartesian coordinate system within the space in which the WPT system 1 is used. The measuring device 500 measures its own position using, for example, known triangulation technology based on the positions of the transmitters 100 and radio waves in the 920 MHz band transmitted from the transmitters 100, but it may also measure its own position using other technologies such as RFID (Radio Frequency Identification) and GPS (Global Positioning System).

[0026] Furthermore, the measuring device 500 measures, for example, the environment of the space in which the WPT system 1 is used. As measurements related to the environment of the space in which the WPT system 1 is used, the measuring device 500 measures, for example, the temperature, humidity, illuminance, carbon dioxide concentration, air pressure, etc. of the space.

[0027] Furthermore, the measuring instrument 500 takes images of the space in which the WPT system 1 is used, for example.

[0028] The measuring device 500 may calculate the power that can be generated by the received power supply signal. For example, the measuring device 500 calculates the intensity of the power that can be generated by radio waves in the 920 MHz band transmitted from the transmitter 100 along three axes in a Cartesian coordinate system. For example, the measuring device 500 performs predetermined statistical processing on the calculated power. The measuring device 500 transmits the processed information to the first information processing device 300, for example, by radio waves in the 2.4 GHz band.

[0029] The first information processing device 300 is an information processing device that monitors the operations of the transmitter 100 and the receiver 200 housed in the WPT system 1. For example, the first information processing device 300 determines whether the transmitter 100 or the receiver 200 is in a preset state based on information about the state of the transmitter 100 and the receiver 200 transmitted from the transmitter 100. If it is determined that the transmitter 100 or the receiver 200 is in a preset state, the first information processing device 300 transmits predetermined information to the second information processing device 400.

[0030] Furthermore, the first information processing device 300 accumulates information about the transmitter 100 and the receiver 200 accommodated in the WPT system 1. For example, the first information processing device 300 stores information about the states of the transmitter 100 and the receiver 200, which is transmitted from the transmitter 100, in a storage unit provided in the first information processing device 300.

[0031] Furthermore, the first information processing device 300 controls the operation of the transmitter 100 housed in the WPT system 1. For example, the first information processing device 300 transmits predetermined instructions or information to the transmitter 100.

[0032] The first information processing device 300 also controls the operation of the second information processing device 400 .

[0033] The first information processing device 300 also monitors the radio wave environment of the space in which the WPT system 1 is installed. The first information processing device 300, for example, stores information transmitted from the measuring device 500 in a storage unit provided in the first information processing device 300. The first information processing device 300 calculates the distribution of electric field strength in the space, for example, based on the stored information and information related to the placement of the transmitter 100. The distribution of electric field strength may be a three-dimensional distribution or a two-dimensional distribution. The first information processing device 300, for example, calculates an appropriate placement of the transmitter 100 based on the calculated electric field strength distribution.

[0034] The second information processing device 400 is, for example, an information processing device operated by an administrator of the WPT system 1. When the second information processing device 400 receives a notification from the first information processing device 300 that the transmitter 100, the receiver 200, or both of them housed in the WPT system 1 are in a predetermined state, the second information processing device 400 notifies the user that the transmitter 100, the receiver 200, or both of them are in the predetermined state.

[0035] Furthermore, the second information processing device 400 analyzes information about the status of the transmitter 100 and the receiver 200 stored in the first information processing device 300, and presents predetermined information to the user. The predetermined information is, for example, the following: Information about the location of the transmitter 100 Information about the location of the receiver 200 Information about power consumption Information about power intensity

[0036] Furthermore, the second information processing device 400 analyzes the information measured by the measuring device 500 and stored in the first information processing device 300, and presents predetermined information to the user. The predetermined information is, for example, the following: Electric field strength distribution within the space Changes over time in the electric field strength distribution within the space Changes in the electric field strength distribution based on changes in the situation within the space (e.g., changes in the placement of the transmitter 100 or parameters) Changes in the electric field strength distribution based on changes in the layout within the space (e.g., changes in the placement of desks, shelves, etc.) Optimal placement of the transmitter 100 (for example, when not calculated by the first information processing device 300)

[0037] 1.1 Configuration of Transmitter and Receiver FIG. 2 is a block diagram illustrating an example configuration of the transmitter 100 and receiver 200 shown in FIG. 1 . As shown in FIG. 2 , the transmitter 100 and the receiver 200 are, for example, spaced apart by a predetermined distance. For example, the transmitter 100 and the receiver 200 are installed at a distance of approximately several meters. Specifically, for example, the transmitter 100 is fixedly installed at a high location indoors, such as a predetermined high position on a ceiling or wall. Depending on how the transmitter 100 is installed, its position can be changed after installation. The receiver 200 is installed in a predetermined device indoors or placed near a device that requires power supply. The receiver 200 may also be carried by a user. Depending on how the receiver 200 is installed, its position can be changed after installation. The transmitter 100 transmits a power supply signal to the receiver 200 using radio waves at a predetermined frequency, for example, the 920 MHz band. The receiver 200 converts the power supply signal transmitted from the transmitter 100 into electric power, and uses the converted electric power to charge or supply the converted electric power to a predetermined device.

[0038] The transmitter 100 includes, for example, an oscillator 101, a transmitting antenna 102, a microcomputer (controller) 103, a data transceiver 104, and a data transmitting / receiving antenna 105. The oscillator 101, the microcomputer 103, the data transceiver 104, the data transmitting / receiving antenna 105, or a combination of at least any of these may be mounted on, for example, a PCB (printed circuit board).

[0039] The oscillator 101 oscillates a signal in a predetermined frequency band, for example, the 920 MHz band. The oscillated signal may be amplified and unwanted frequency components may be removed, if necessary.

[0040] The transmitting antenna 102 is configured to be able to efficiently transmit radio waves in the 920 MHz band, for example, and emits a signal modulated by a modulator 107 as a power supply signal.

[0041] The microcomputer 103 controls the operation of the transmitter 100. The microcomputer 103 is realized by, for example, a semiconductor device equipped with an ARM processor. The microcomputer 103 controls, for example, the transmission of radio waves by the transmission antenna 102.

[0042] The data transceiver 104 performs processes such as converting digital data to analog and modulating analog data. The data transceiver 104 also performs processes such as demodulating a data signal received by the data transceiver antenna 105 and digitizing the demodulated data. For example, the data transceiver 104 extracts a predetermined signal from the data signal received by the data transceiver antenna 105, converts it into digital data, and transmits it to the microcomputer 103.

[0043] The data transmission / reception antenna 105 is configured to be able to efficiently transmit and receive radio waves in the 2.4 GHz band, for example. The data transmission / reception antenna 105 radiates data signals supplied from the data transceiver 104. The data transmission / reception antenna 105 also receives data signals transmitted from the receiver 200.

[0044] The receiver 200 includes, for example, a receiving antenna 201, a rectifier 202, a power management unit 203, a power storage unit 204, a microcomputer 205, a data transceiver 206, and a data transmitting / receiving antenna 207. The receiving antenna 201, the rectifier 202, the power management unit 203, the power storage unit 204, the microcomputer 205, the data transceiver 206, the data transmitting / receiving antenna 207, or a combination of at least any of these may be mounted on, for example, a PCB or an FPC (flexible printed circuit board).

[0045] The receiving antenna 201 is configured to be able to efficiently receive radio waves in the 920 MHz band, for example. The receiving antenna 201 receives the power supply signal radiated from the transmitting antenna 102.

[0046] The rectifier 202 rectifies the radio waves received as the power supply signal and converts them into a DC voltage.

[0047] The power management unit 203 manages the DC voltage. For example, the power management unit 203 controls a charging voltage based on the DC voltage. The power management unit 203 charges the power storage unit 204 by controlling the charging voltage. Furthermore, for example, when the power storage unit 204 stores power equal to or greater than a predetermined capacity, the power management unit 203 supplies the DC voltage to a connected component.

[0048] Furthermore, the power management unit 203 discharges the power stored in the power storage unit 204 in response to control from the microcomputer 205 .

[0049] The power storage unit 204 stores power in response to an instruction from the power management unit 203. The power storage unit 204 is realized by, for example, a battery or a capacitor. The power storage unit 204 also discharges the stored power in response to an instruction from the power management unit 203.

[0050] The microcomputer 205 controls the operation of the receiver 200. The microcomputer 205 is driven by a DC voltage supplied from the power management unit 203 or by power stored in the power storage unit 204. The microcomputer 205 controls the power management unit 203 to cause the power storage unit 204 to release the power stored therein.

[0051] For example, various sensors can be connected to the receiver 200. For example, a heat sensor, a temperature sensor, a light sensor, a humidity sensor, a vibration sensor, etc. are connected to the receiver 200. The sensors connected to the receiver 200 are driven, for example, by a DC voltage supplied from the power management unit 203 or by power discharged from the power storage unit 204. The microcomputer 205 continuously or intermittently monitors the voltage values ​​at predetermined locations of the receiver 200, the status of the sensors connected to the receiver 200, information detected by the sensors, etc. The microcomputer 205 transmits the voltage values ​​at predetermined locations of the receiver 200, the status of the sensors connected to the receiver 200, information detected by the sensors, etc. as digital data to the data transceiver 206. Note that the sensors may be built into the receiver 200.

[0052] The data transceiver 206 performs processes such as converting digital data supplied from the microcomputer 205 into analog data and modulating the analog data. The data transceiver 206 also performs processes such as demodulating a data signal received by a data transmission / reception antenna 207 and digitizing the demodulated data. The data transceiver 206 is driven by, for example, a DC voltage supplied from the power management unit 203 or power discharged from the power storage unit 204.

[0053] The data transmission / reception antenna 207 is configured to be able to efficiently transmit and receive radio waves in the 2.4 GHz band, for example. The data transmission / reception antenna 207 radiates data signals supplied from the data transceiver 206. The data transmission / reception antenna 207 also receives data signals transmitted from the transmitter 100. For example, the data transmission / reception antenna 207 is driven by a DC voltage supplied from the power management unit 203 or power discharged from the power storage unit 204.

[0054] 1.2 Measuring Device Configuration Fig. 3 is a perspective view showing an example of the appearance and configuration of measuring device 500 shown in Fig. 1. Measuring device 500 shown in Fig. 3 is placed in a space to be measured, such as a space in which WPT system 1 is used. Measuring device 500 is configured, for example, with a housing 51, an expandable section 52, an insulating section 53, and a measuring section 54.

[0055] The housing 51 is the main body of the measuring device 500 and is made of, for example, a resin such as polyvinyl chloride, and has a disk-like shape as shown in Fig. 3. While Fig. 3 shows an example in which the housing 51 has a disk-like shape, the shape is not limited to this. For example, tires or the like that can move on the floor are attached to the underside (not shown) of the housing 51, and the housing 51 is configured to be freely movable on the plane indicated by the arrows X and Y in Fig. 3, i.e., on the floor of the space in which the WPT system 1 is used.

[0056] The extension / contraction unit 52 is provided to protrude from the top surface of the housing 51 and supports the insulating unit 53 and the measuring unit 54. It is made of resin such as polyvinyl chloride and has a long cylindrical shape as shown in FIG. 3 . While FIG. 3 shows an example in which the extension / contraction unit 52 has a cylindrical shape, the shape is not limited to this. The extension / contraction unit 52 is configured to be freely extendable and retractable in the vertical direction indicated by arrow Z in FIG. 3 , i.e., in the height direction of the space in which the WPT system 1 is used. Furthermore, the extension / contraction unit 52 is configured to be rotatable in a planar direction around a rotation axis centered on the center of the housing 51, as shown by arrow R1 in FIG. 3 .

[0057] The insulating part 53 is provided on the other end side of the expandable part 52 extending from the housing 51, and is a part that supports the measuring part 54. It is made of a material with excellent insulating properties, such as polyimide, and has a disk-like shape as shown in Fig. 3. Although Fig. 3 shows an example in which the insulating part 53 has a disk-like shape, the shape is not limited to this.

[0058] The measuring unit 54 is placed above the insulating unit 53 and is a part where various sensors for measuring the electric field strength in the space where the WPT system 1 is used, the position of the measuring device 500, and the environment in the space, and a camera for photographing the space are provided, and is realized by being covered with a resin such as polyvinyl chloride, for example, and provided with a gap for taking in air in the space and a photographing window for photographing with the camera, and has a disk-like shape as shown in Fig. 3. Although Fig. 3 shows an example in which the shape of the measuring unit 54 is disk-like, the shape is not limited to this.

[0059] The insulating unit 53 and the measuring unit 54 are configured to be rotatable in a direction inclined relative to the floor surface of the space in which the WPT system 1 is used, as shown by arrow L in Fig. 3. The insulating unit 53 and the measuring unit 54 are also configured to be rotatable about a rotation axis parallel to the floor surface of the space, as shown by arrow R2 in Fig. 3. The insulating unit 53 and the measuring unit 54 are configured to be rotatable in the same direction as the expandable unit 52 rotates in the direction of arrow R1.

[0060] Fig. 4 is a block diagram showing an example of the functional configuration of the measuring device 500 shown in Fig. 1. The measuring device 500 includes, for example, an electric field measuring antenna 501, an electric field strength measuring unit 502, a position measuring antenna 503, a position measuring unit 504, an environment measuring sensor 505, an environment measuring unit 506, a camera 507, a power storage unit 508, a drive control unit 509, a microcomputer 510, a data transceiver 511, and a data transmitting / receiving antenna 512. At least any combination of these components may be mounted on, for example, a PCB or an FPC (flexible printed circuit board).

[0061] The electric field measurement antenna 501 is formed to be able to efficiently receive radio waves in the 920 MHz band, for example. The electric field measurement antenna 501 is formed, for example, along three axes in a Cartesian coordinate system. That is, the electric field measurement antenna 501 has an antenna element formed along the x-axis, an antenna element formed along the y-axis, and an antenna element formed along the z-axis. Each antenna element is realized, for example, by a dipole antenna. Note that a monopole antenna may also be used. Each antenna element has a length (for example, approximately 40 mm) corresponding to the wavelength of radio waves in the 920 MHz band, for example. The electric field measurement antenna 501 receives a power supply signal radiated from the transmitting antenna 102.

[0062] The electric field strength measurement unit 502 measures the electric field strength based on the strength of the signal received by the electric field measurement antenna 501. Specifically, the electric field strength measurement unit 502 measures the electric field strength based on the strength of the signal received for each antenna element of the electric field measurement antenna 501, for example, to acquire information about the electric field strength. In other words, the electric field measurement antenna 501 and the electric field strength measurement unit 502 constitute an electric field sensor. The electric field strength measurement unit 502 measures the electric field strength at a predetermined cycle, for example. The predetermined cycle is, for example, multiple times per second (approximately 1,000 times). The electric field strength measurement unit 502 outputs the measurement result to the microcomputer 510. The measurement result may be accompanied by a timestamp indicating the time the measurement was performed.

[0063] The position measurement antenna 503 has, for example, the same configuration as the electric field measurement antenna 501, and is formed, for example, along three axes in a Cartesian coordinate system. Note that if the position measurement antenna 503 can be used in common with the electric field measurement antenna 501, the electric field measurement antenna 501 may realize the function of the position measurement antenna 503.

[0064] The position measurement unit 504 measures the position of the measuring device 500 (measuring unit 54) in the space in which the WPT system 1 is used based on the signal received by the position measurement antenna 503, and acquires position information. In other words, the position measurement antenna 503 and the position measurement unit 504 constitute a position sensor. Note that the position measurement antenna 503 and the position measurement unit 504 are not essential components, and for example, the drive control unit 509 may measure the amount of movement of the measuring device 500 and acquire position information of the measuring device 500.

[0065] The environmental measurement sensor (environmental sensor) 505 is composed of, for example, a sensor for measuring the environment of the space in which the WPT system 1 is used, specifically, the temperature, humidity, illuminance, carbon dioxide concentration, air pressure, etc. of the space.

[0066] The environment measurement unit 506 measures the environment in the space in which the WPT system 1 is used based on the signal detected by the environment measurement sensor 505, and acquires environmental information.

[0067] The camera 507 is a device that receives light using, for example, a light receiving element and outputs the received light as an image capturing signal, captures an image of the space in which the WPT system 1 is used, and acquires captured image information (captured image). Specifically, the camera 507 is configured by a wireless camera or the like.

[0068] The power storage unit 508 stores, for example, power supplied from an external source. The power storage unit 508 is realized by, for example, a battery or a capacitor. The power storage unit 508 may also store power generated by a power supply signal transmitted from the transmitter 100. When the measuring device 500 is connected to the receiver 200, the measuring device 500 may use the power storage unit 204 of the receiver 200. When the measuring device 500 is built into the receiver 200, the measuring device 500 may use the power storage unit 204 of the receiver 200.

[0069] The drive control unit 509 controls, for example, the movement of the housing 51 within the space in which the WPT system 1 is used. For example, the drive control unit 509 controls the housing 51 to move in the plane indicated by the arrows X and Y in Fig. 3, and to move while avoiding an obstacle if one is present in the moving direction. The measuring instrument 500 may be equipped with various sensors for realizing such control, but these are not shown.

[0070] The microcomputer 510 controls the operation of the measuring device 500. The microcomputer 510 also performs statistical processing based on the measurement results measured by the field strength measurement unit 502. Statistical processing includes, for example, calculating an average value over a predetermined period and calculating a peak value over a predetermined period. However, statistical processing is not limited to these, and various other types of processing are possible. The predetermined period corresponds to, for example, the period at which the measuring device 500 transmits information about the measurement results. The predetermined period may be the same as or shorter than the period at which the measuring device 500 transmits information about the measurement results. The microcomputer 510 outputs, as information about the measurement results, information after statistical processing or information measured by the field strength measurement unit 502 to the data transceiver 511. For example, the microcomputer 510 outputs information about the measurement results together with the date and time at which the measurement was performed.

[0071] The microcomputer 510 may calculate the power generated when the device itself is the receiver 200 based on the measurement results measured by the field strength measurement unit 502. Specifically, for example, the microcomputer 510 stores information related to the efficiency of a rectifier. For example, the efficiency of the rectifier varies depending on the strength of the received power supply signal and the magnitude of the connected load (the magnitude of the load of the application executed by the generated power). The microcomputer 510 calculates the power based on the information related to the rectifier efficiency and the measurement results measured by the field strength measurement unit 502. The microcomputer 510 performs statistical processing on data related to the calculated power. The microcomputer 510 outputs the data after the statistical processing to the data transceiver 511. The microcomputer 510 may calculate the power based on the data after the statistical processing.

[0072] A power switch may be connected to the microcomputer 510. Pressing the power switch inputs whether or not to operate the measuring device 500. When the user turns the power switch on, the microcomputer 510 operates. When the user turns the power switch off, the microcomputer 510 stops.

[0073] The data transceiver 511 performs processes such as converting digital data output from the microcomputer 510 into analog data and modulating the analog data. The data transceiver 511 also performs processes such as demodulating a data signal received by the data transmission / reception antenna 512 and digitizing the demodulated data.

[0074] The data transmission / reception antenna 512 is configured to be able to efficiently transmit and receive radio waves in the 2.4 GHz band, for example. The data transmission / reception antenna 512 radiates the data signal output from the data transceiver 511. The data transmission / reception antenna 512 also receives the data signal transmitted from the first information processing device 300.

[0075] 5 is a diagram showing an example of the functional configuration of the first information processing device 300. As shown in Fig. 5, the first information processing device 300 functions as a communication unit 301, a storage unit 302, and a control unit 303.

[0076] The communication unit 301 performs processing for the first information processing device 300 to communicate with other devices, for example, the transmitter 100 , the receiver 200 , and the measuring device 500 .

[0077] The storage unit 302 has, for example, a spatial information table 3021, a measurement result table 3022, etc. The tables stored in the storage unit 302 are not limited to these. In addition to these, the storage unit 302 also stores, for example, tables that store information about the states of the transmitter 100 and the receiver 200.

[0078] The space information table 3021 is a table that stores information about the space to be measured, and will be described in detail later.

[0079] The measurement result table 3022 is a table that stores information related to the measurement results, which will be described in detail later.

[0080] The control unit 303 is realized by the processor reading a program stored in the storage unit and executing instructions included in the program. By operating in accordance with the program, the control unit 303 performs functions shown as a reception control module 3031, a transmission control module 3032, a storage module 3033, a generation module 3034, and a proposal module 3035.

[0081] The reception control module 3031 controls the process in which the first information processing device 300 receives signals from other devices, such as the transmitter 100, the second information processing device 400, and the measuring device 500, in accordance with a communication protocol.

[0082] The transmission control module 3032 controls the process in which the first information processing device 300 transmits signals to other devices, such as the transmitter 100, the second information processing device 400, and the measuring device 500, in accordance with a communication protocol.

[0083] The storage module 3033 stores information acquired from the transmitter 100 and the measuring device 500 in the storage unit 302. Specifically, for example, information related to measurement results is transmitted from the measuring device 500 at a predetermined interval. The storage module 3033 acquires information output from the measuring device 500 and stores the acquired information in the measurement result table 3022.

[0084] The generation module 3034 generates a distribution map of the space to be measured based on information related to the measurement of the electric field strength. Specifically, for example, the generation module 3034 references the measurement result table 3022 and generates a distribution map of the electric field strength in the space. The generation module 3034 may generate a two-dimensional distribution map or a three-dimensional distribution map. If the power has been calculated by the measuring device 500, the generation module 3034 may generate a power distribution map.

[0085] Furthermore, the generation module 3034 generates a floor map (space map) of the space to be measured based on information related to position measurement by the position measurement unit 504 of the measuring device 500. Specifically, for example, based on information about the position to which the measuring device 500 has moved, such as coordinates, the range on a plane in which the measuring device 500 can move and the range on a plane in which the measuring device 500 cannot move are identified, and the range in which the measuring device 500 can move is mapped as the range of that floor, thereby generating a floor map. Furthermore, the generation module 3034 may generate not only a planar floor map, but also a three-dimensional map including information in the vertical direction.

[0086] The proposal module 3035 calculates an optimal placement of the transmitters 100 for the space based on a distribution map within the space. The proposal module 3035 may calculate the optimal placement of the transmitters 100 by taking into account not only changes in the positions of the transmitters 100 but also, for example, an increase or decrease in the number of transmitters 100. The proposal module 3035 may also calculate the optimal placement of the transmitters 100 by changing not only the placement of the transmitters 100 but also parameters such as the direction in which the transmitters 100 are placed and the strength of the radio waves emitted. The proposal module 3035 may, for example, estimate the relationship between the electric field and the transmitters 100 based on the calculated distribution map, and adjust the number, positions, and parameters of the transmitters 100 so that the electric field strength in the space is at a recommended level. Furthermore, the proposal module 3035 may perform a predetermined authentication of the transmitters 100, specifically, authentication that certain conditions are met, based on the measurement results of the electric field strength, and output the result.

[0087] 6 and 7 are diagrams showing the data structures of tables stored in the first information processing device 300. Note that FIGS. 6 and 7 are merely examples and do not exclude data that is not listed. Furthermore, data listed in the same table may be stored in separate storage areas in the storage unit 302.

[0088] 6 is a schematic diagram showing an example of the data structure of a spatial information table 3021 stored in the first information processing device 300. The spatial information table 3021 shown in Fig. 6 is a table having columns for space ID, setting date and time, spatial information, transmitter, receiver, and measuring device, with a setting ID as a key, for example. The information stored in the spatial information table 3021 is, for example, information measured by the position measurement unit 504 of the measuring device 500.

[0089] The setting ID is an item for storing identification information of a setting. The space ID is an item for storing identification information of a space. The setting date and time is an item for storing the date and time when information about a space was set. The space information is an item for storing registered information about a space. The space information includes, for example, the vertical distance of the room, the horizontal distance of the room, the height of the room, information about the materials that form the space, information about objects placed in the space, information about loss of radio wave intensity in the space, or at least any combination of these. The information about the materials that form the space includes, for example, floor materials, ceiling materials, wall materials, window glass materials, or at least any combination of these. The information about objects placed in the space includes, for example, the positions of objects such as desks and chairs, the types of objects, the materials of the objects, or at least any combination of these. The space information may be stored in advance or may be set by the user. The space information is not limited to these. For example, any of the above information may be omitted, or information other than the above information may be included.

[0090] The transmitter is an item that stores information about the transmitter 100. The item "transmitter" includes coordinates where the transmitter 100 is located, transmission gain, transmission intensity, or at least any combination of these. The receiver is an item that stores information about the receiver 200. The item "receiver" includes coordinates where the receiver 200 is located, reception gain, rectification efficiency, or at least any combination of these. The measuring device is an item that stores information about the measuring device 500. The item "measuring device" includes coordinates where the measuring device 500 is located, etc.

[0091] Fig. 7 is a schematic diagram showing an example of the data structure of the measurement result table 3022 stored in the first information processing device 300. The measurement result table 3022 shown in Fig. 7 is a table having columns of measurement date and time, field strength, and coordinates, with a setting ID as a key, for example.

[0092] The measurement date and time is an item that stores the date and time when the measurement was performed. The field strength is an item that stores the measured field strength. The field strength item may store information that has been subjected to statistical processing, or may store information before statistical processing. The coordinates are an item that stores the position when the field strength was measured.

[0093] <4 Operation> Fig. 8 is a flowchart showing an example of the operation of measuring device 500. Fig. 8 will be explained assuming that transmitter 100 and measuring device 500 are arranged as shown in Fig. 9, for example.

[0094] 9 is a diagram showing an example of the spatial arrangement of transmitter 100 and measuring device 500. Transmitter 100 and measuring device 500 are placed in a room, for example, 10 m in the x direction and 10 m in the y direction. Transmitters 100 are placed, for example, at intervals of 3 m. Measuring devices 500 are placed, for example, so that their positions in the y direction are aligned with those of transmitters 100 and their positions in the x direction are located between transmitters 100.

[0095] In step S11, the measuring device 500 is controlled by the drive control unit 509 to move within the space in which the WPT system 1 is used.

[0096] In step S12, measuring device 500 measures the electric field strength at a predetermined cycle. Specifically, electric field measuring antenna 501 receives radio waves in the 920 MHz band transmitted from transmitter 100 using antenna elements 5011, 5012, and 5013 arranged along three axes in a Cartesian coordinate system. Field strength measuring unit 502 measures the electric field strength for each axis based on the strength of the radio waves received by antenna elements 5011, 5012, and 5013, for example, at a cycle of multiple times per second.

[0097] In step S12, the measuring device 500 performs statistical processing on the measured field strength. Specifically, the microcomputer 510 calculates the field strength for one second based on the field strength measured during that one second. More specifically, the microcomputer 510 calculates the field strength for that one second by averaging the field strengths measured during that one second. The microcomputer 510 also determines the peak value of the field strength measured during that one second as the field strength for that one second. The period for statistical processing is not limited to one second and may be longer than one second.

[0098] In step S13, the measuring device 500 measures the position of the measuring device 500 (measurement unit 54) in the space where the WPT system 1 is used, at the timing when the electric field strength was measured in step S12. Note that the period for measuring the position may be shorter than the period when the electric field strength was measured. Also, in step S13, the measuring device 500 may measure the environment of the space where the WPT system 1 is used, specifically, the temperature, humidity, illuminance, carbon dioxide concentration, air pressure, etc., at the timing when the electric field strength was measured in step S12 or at another timing. Furthermore, in step S13, the measuring device 500 may photograph the space where the WPT system 1 is used, at the timing when the electric field strength was measured in step S12 or at another timing.

[0099] In step S14, the measuring device 500 associates the measurement result of the electric field strength measured in step S12 with the measurement result of the position measured in step S13. Specifically, the measuring device 500 associates the coordinates as position information at which the electric field strength was measured with the electric field strength at that position so that the measurement result of the electric field strength can be grasped for each position in the space where the WPT system 1 is used. At this time, the measuring device 500 may also associate the coordinates with the measurement result related to the spatial environment.

[0100] In step S15, the measuring device 500 transmits the processed information to the first information processing device 300. Specifically, the microcomputer 510 transmits the statistically processed information to the first information processing device 300 at a predetermined cycle. The predetermined cycle may coincide with the period for the statistical processing or may be longer than the period. The microcomputer 510 may transmit the average value and peak value of the electric field strength to the first information processing device 300. The microcomputer 510 may transmit the difference between the average value and peak value of the electric field strength to the first information processing device 300. The microcomputer 510 may transmit measurement results that have not been subjected to statistical processing to the first information processing device 300.

[0101] When the first information processing device 300 receives information related to the measurement from the measuring device 500, it stores the received information in the measurement result table 3022. For example, when the second information processing device 400 requests specific information, the first information processing device 300 executes processing in accordance with the request. For example, when the second information processing device 400 requests the electric field strength distribution in space, the generation module 3034 generates a distribution map of the space to be measured based on the information related to the measurement stored in the measurement result table 3022.

[0102] FIG. 10 is a schematic diagram illustrating an example of a distribution map generated by the generation module 3034. In FIG. 10, the space is divided into a predetermined grid, and the color of the grid represents the electric field strength. The electric field strength is output based on the position information of the measuring device 500. The division of the grid is set, for example, based on the arrangement of the measuring device 500. The grid may be set by arranging the measuring device 500, or the measuring device 500 may be arranged according to the grid. At this time, measurement results related to the spatial environment may also be output. At this time, the device may be configured to accept input of predetermined conditions, such as a condition of having an electric field strength equal to or greater than a predetermined level, or a condition of the electric field strength of predetermined position information, and to output only grids that meet the accepted conditions.

[0103] Also, for example, when the second information processing device 400 requests the change in the electric field strength distribution over time, the generation module 3034 generates a distribution diagram of the electric field strength at multiple points in time based on the information about the measurement stored in the measurement result table 3022.

[0104] Furthermore, for example, when a change in the field strength distribution based on a change in the situation in the space or a change in the layout is requested by the second information processing device 400, the generation module 3034 references the space information table 3021 and acquires the date and time when the settings related to the space were updated. The generation module 3034 acquires information about measurements before and after the update based on the measurement result table 3022, and generates a field strength distribution map based on the acquired information.

[0105] Also, for example, when the second information processing device 400 requests a proposal for improving the distribution of electric field strength, the proposal module 3035 calculates the placement of the transmitter 100 appropriate for the space based on a distribution map within the space.

[0106] Fig. 11 is a diagram showing an example of the spatial arrangement of transmitter 100 and measuring device 500. Unlike the example shown in Fig. 9, in Fig. 11, transmitter 100 is not located at (x, y) = (6, 3).

[0107] FIG. 12 is a schematic diagram showing an example of a distribution map when transmitters 100 are placed as shown in FIG. 11. In FIG. 12, grids 31 and 32 have lower electric field strength than other grids. The proposal module 3035 estimates the association between the electric field and the transmitter 100, and adjusts the number, position, and parameters of the transmitter 100 so that the electric field strength in space is at a recommended level. The proposal module 3035 proposes placing the transmitter 100 between grid 31 and grid 32 in FIG. 12, i.e., at (x, y) = (6, 3).

[0108] As described above, in the above embodiment, the WPT system 1 includes one or more transmitters 100, one or more receivers 200, multiple measuring devices 500, and a first information processing device 300. The transmitter 100 is installed in a measurement target space and transmits a power supply signal. The receiver 200 generates power in response to the power supply signal. The measuring device 500 is configured to be movable within the measurement target space, measures the electric field strength at each position as it moves, and measures its position using a position sensor. The first information processing device 300 generates an electric field strength distribution within the measurement target space based on the electric field strength measured by the measuring device 500 and position information. At this time, the first information processing device 300 may generate the electric field strength distribution within the measurement target space based on the electric field strength measured by the measuring device 500 and pre-stored space information. This allows the first information processing device 300 to acquire the electric field strength within the space in real time.

[0109] Therefore, the WPT system 1 according to this embodiment makes it possible to grasp the strength of radio waves in an indoor space.

[0110] In the above embodiment, the measuring device 500 measures the environment of the measurement target space and outputs the measurement results in association with the electric field strength, thereby making it possible to grasp the radio wave strength according to the conditions of the indoor space.

[0111] In the above embodiment, the measuring device 500 captures an image of the space to be measured and outputs the image in association with the measurement result of the electric field strength, thereby making it possible to grasp the strength of the radio waves according to the conditions of the indoor space.

[0112] In the above embodiment, the measuring device 500 generates a floor map (space map) of the space to be measured, which makes it possible to grasp the space to be measured and measure the electric field strength even when detailed information about the indoor space is not available.

[0113] In the above embodiment, the first information processing device 300 outputs information on the electric field strength in a floor map (space map) based on a predetermined condition, thereby making it possible to grasp the electric field strength that matches the predetermined condition.

[0114] <Modification> In the above embodiment, the first information processing device 300 generates the electric field strength distribution. However, the measuring device 500 may generate the electric field strength distribution. In this case, for example, at least one of the multiple measuring devices 500 collects measurement-related information from the other measuring devices 500. The measuring device 500 that has collected the information generates an electric field strength distribution or a power distribution based on the collected information.

[0115] Furthermore, in the above-described embodiments, the present invention has been described as being applied to a so-called WPT system 1 in which transmission power consisting of an AC signal is wirelessly transmitted from the transmitter 100 to the receiver 200. However, the present invention can also be applied to systems that provide power to the receiver 200 by other methods. Since such systems are known, detailed description thereof will be omitted. Examples include a system that transmits power generated by solar power generation to the receiver 200 via a wired or wireless connection, and a system that transmits power to the receiver 200 via a laser beam via a wired or wireless connection. The present invention can also be applied to a configuration in which vibration or sound is applied to the receiver 200, and the receiver 200 converts the power of the vibration or the like into electric power. Furthermore, the present invention can also be applied to systems that use known contactless power supply technologies other than those that wirelessly receive transmission power consisting of an AC signal, such as a contactless power supply technology using a magnetic field coupling system.
