＜Overview＞
In a wireless power transfer (WPT) system, there are one or more transmitters that transmit a power supply signal and multiple receivers that receive the power supply signal. One or more measuring devices measure the electric field strength based on the power supply signal transmitted by the transmitter. An information processing device calculates an electric field strength distribution in a measurement target space (indoor space) based on the electric field strength measured by the measuring device.

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

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 or a factory. A building is an example of a structure, and is not limited to a building as long as it is an indoor space where a specific activity such as business or office work is 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.

In FIG. 1, an example is shown 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 four or more.

In FIG. 1, an example is shown 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.

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 described below, the receiver 200 may transmit, for example, information regarding the state of the receiver 200 or information regarding the measurement results of a sensor as a data signal to the transmitter 100, and the transmitter 100 may receive such a data signal. In this case, the transmitter 100 is a receiver that receives a data signal, and the receiver 200 functions as a transmitter that transmits a data signal.

In FIG. 1, an example is shown 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 number of measuring devices 500 included in the WPT system 1 may be one, or three or more. The measuring devices 500 are provided, for example, so as to be movable within the space in which the WPT system 1 is used.

In FIG. 1, an example is shown 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.

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

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.

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 multiple 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 regarding the state of the transmitter 100 to the first information processing device 300.

The receiver 200 receives, for example, a power supply signal or a data signal transmitted from the transmitter 100. For example, if the receiver 200 has 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. For example, if the receiver 200 has a specified 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.

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

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, a 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.

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 its position (coordinates) along three axes in a Cartesian coordinate system within the space in which the WPT system 1 is used, for example. The measuring device 500 measures its own position using triangulation technology, which is a known technology, for example, using the known 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).

The measuring device 500 also performs measurements related to the environment of the space in which the WPT system 1 is used, for example. The measuring device 500 measures the temperature, humidity, illuminance, carbon dioxide concentration, air pressure, etc., of the space as measurements related to the environment of the space in which the WPT system 1 is used.

Furthermore, the measuring device 500, for example, takes photographs of the space in which the WPT system 1 is used.

The measuring device 500 may calculate the power that may be generated by the received power supply signal. For example, the measuring device 500 calculates the intensity of the power that may 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 a 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.

The first information processing device 300 is an information processing device that monitors the operation of the transmitter 100 and 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 specified information to the second information processing device 400.

The first information processing device 300 also accumulates information about the transmitter 100 and receiver 200 housed in the WPT system 1. For example, the first information processing device 300 stores information about the status of the transmitter 100 and the receiver 200 transmitted from the transmitter 100 in a storage unit provided in the first information processing device 300.

The first information processing device 300 also controls the operation of the transmitter 100 housed in the WPT system 1. For example, the first information processing device 300 transmits a predetermined instruction or information to the transmitter 100.

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

The first information processing device 300 also monitors the radio wave environment in the space in which the WPT system 1 is constructed. 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 the 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 the 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.

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 notification from the first information processing device 300 that the transmitter 100, the receiver 200, or both of these contained in the WPT system 1 are in a specified state, it presents to the user that the transmitter 100, the receiver 200, or both of these are in the specified state.

Moreover, the second information processing device 400 analyzes information on 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 regarding the placement of the transmitter 100 Information regarding the placement of the receiver 200 Information regarding power consumption Information regarding power intensity

In addition, 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 in the space Change over time in the electric field strength distribution in the space Change in the electric field strength distribution based on a change in the situation in the space (e.g., a change in the placement of the transmitter 100 or a change in parameters) Change in the electric field strength distribution based on a change in the layout in the space (e.g., a change in the placement of desks, shelves, etc.) Optimal placement of the transmitter 100 (e.g., when not calculated by the first information processing device 300)

<1.1 Transmitter and receiver configuration>
FIG. 2 is a block diagram showing an example of the configuration of the transmitter 100 and the receiver 200 shown in FIG. 1. As shown in FIG. 2, the transmitter 100 and the receiver 200 are, for example, spaced apart from each other at a predetermined interval. For example, the transmitter 100 and the receiver 200 are installed at a distance of about several meters. Specifically, for example, the transmitter 100 is fixed and installed at a predetermined high position provided in a high place indoors, for example, on a ceiling or a wall. The transmitter 100 can be changed in position after installation depending on how it is installed. 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. The receiver 200 can be changed in position after installation depending on how it is installed. The transmitter 100 transmits a power supply signal to the receiver 200 by radio waves of a predetermined frequency, for example, 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.

The transmitter 100 has, 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 at least any combination of these, may be mounted on, for example, a PCB (printed circuit board).

The oscillator 101 oscillates a signal in a specific frequency band, for example, the 920 MHz band. If necessary, the oscillated signal may be amplified and unnecessary frequency components may be removed.

The transmitting antenna 102 is configured to be capable of efficiently transmitting radio waves in the 920 MHz band, for example. The transmitting antenna 102 radiates a signal modulated by the modulator 107 as a power supply signal.

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

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 the data signal received by the data transmission/reception antenna 105 and digitizing the demodulated data. For example, the data transceiver 104 extracts a specific signal from the data signal received by the data transmission/reception antenna 105, converts it into digital data, and transmits it to the microcomputer 103.

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 the data signal supplied from the data transceiver 104. The data transmission/reception antenna 105 also receives the data signal transmitted from the receiver 200.

The receiver 200 has, 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 transmission/reception 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, and the data transmission/reception antenna 207, or at least any combination of these, may be mounted on, for example, a PCB or an FPC (flexible printed circuit board).

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.

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

The power management unit 203 manages the DC voltage. For example, the power management unit 203 controls the charging voltage based on the DC voltage. The power management unit 203 charges the power storage unit 204 by controlling the charging voltage. In addition, 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 member.

In addition, the power management unit 203 releases the power stored in the power storage unit 204 in response to control from the microcontroller 205.

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, for example, by a battery or a capacitor. The power storage unit 204 also releases the stored power in response to an instruction from the power management unit 203.

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 the power stored in the power storage unit 204. The microcomputer 205 controls the power management unit 203 and causes the power stored in the power storage unit 204 to be released.

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 direct current 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 value at a specific portion of the receiver 200, the status of the sensor connected to the receiver 200, information detected by the sensor, etc. The microcomputer 205 transmits the voltage value at a specific portion of the receiver 200, the status of the sensor connected to the receiver 200, information detected by the sensor, etc. as digital data to the data transceiver 206. The sensor may be built into the receiver 200.

The data transceiver 206 performs processes such as converting digital data supplied from the microcomputer 205 to analog and modulating the analog data. The data transceiver 206 also performs processes such as demodulating a data signal received by the data transceiver antenna 207 and digitizing the demodulated data. The data transceiver 206 is 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 data transmission/reception antenna 207 is formed to be capable of efficiently transmitting and receiving radio waves in the 2.4 GHz band, for example. The data transmission/reception antenna 207 radiates a data signal supplied from the data transceiver 206. The data transmission/reception antenna 207 also receives a data signal 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 by power discharged from the power storage unit 204.

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

The housing 51 is the main body of the measuring device 500, and is made of resin such as polyvinyl chloride, and has a disk-like shape as shown in FIG. 3. Although FIG. 3 shows an example of the housing 51 having 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 of the housing 51 (not shown), and the housing 51 is configured to be freely movable on the plane indicated by the arrows XY in FIG. 3, i.e., on the floor of the space in which the WPT system 1 is used.

The telescopic section 52 is provided to protrude from the top surface of the housing 51 and is a section that supports the insulating section 53 and the measuring section 54. It is made of a resin such as polyvinyl chloride, and has a long cylindrical shape as shown in FIG. 3. Although FIG. 3 shows an example in which the telescopic section 52 has a cylindrical shape, the shape is not limited to this. The telescopic section 52 is configured to be freely telescopic in the vertical direction indicated by the arrow Z in FIG. 3, that is, in the height direction of the space in which the WPT system 1 is used. In addition, the telescopic section 52 is configured to be rotatable in a planar direction around a rotation axis centered on the central part of the housing 51, as indicated by the arrow R1 in FIG. 3.

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 Figure 3. In Figure 3, an example of the insulating part 53 having a disk-like shape is shown, but the shape is not limited to this.

The measuring unit 54 is placed above the insulating unit 53 and is a part in which various sensors for measuring the electric field strength in the space in which 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. For example, the measuring unit 54 is covered with a resin such as polyvinyl chloride and has a gap for taking in air from 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 measuring unit 54 has a disk-like shape, the shape is not limited to this.

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 also configured to be rotatable in the same direction as the expanding and contracting unit 52 rotates in the direction of arrow R1.

Figure 4 is a block diagram showing an example of the functional configuration of the measuring device 500 shown in Figure 1. The measuring device 500 has, 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 environmental measuring sensor 505, an environmental 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 may be implemented, for example, on a PCB or FPC (flexible printed circuit board).

The electric field measurement antenna 501 is formed so as 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, about 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 transmission antenna 102.

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 and acquires information on 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. That is, 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 period, for example. The predetermined period is, for example, multiple times (approximately 1000 times) per second. 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 when the measurement was performed.

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 function of the position measurement antenna 503 may be realized by the electric field measurement antenna 501.

Based on the signal received by the position measurement antenna 503, 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, 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.

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.

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

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

The power storage unit 508 stores, for example, power supplied from an external source. The power storage unit 508 is realized, for example, by a battery or a capacitor. The power storage unit 508 may 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.

The drive control unit 509, for example, controls 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 on the plane indicated by the arrows XY in FIG. 3, and to move while avoiding an obstacle if one is present in the direction of travel. The measuring device 500 may be equipped with various sensors to achieve such control, but these are not shown in the figure.

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 electric field strength measuring unit 502. The statistical processing includes, for example, calculation of an average value in a predetermined period and calculation of a peak value in a predetermined period. Note that the statistical processing is not limited to these, and various processing can be performed. The predetermined period is, for example, a period corresponding to the period in which the measuring device 500 transmits information about the measurement result. The predetermined period may be the same as the period in which the measuring device 500 transmits information about the measurement result, or may be shorter. The microcomputer 510 outputs information about the measurement result, such as information after statistical processing or information measured by the electric field strength measuring unit 502, to the data transceiver 511. The microcomputer 510 outputs information about the measurement result, such as the date and time when the measurement was performed.

The microcomputer 510 may calculate the generated power based on the measurement results measured by the electric field strength measurement unit 502, assuming that the device itself is the receiver 200. Specifically, for example, the microcomputer 510 stores information about the efficiency of the rectifier. For example, the efficiency of the rectifier varies depending on the strength of the received power supply signal and the size of the connected load (the size of the load of the application executed by the generated power). The microcomputer 510 calculates the power based on the information about the efficiency of the rectifier and the measurement results measured by the electric field strength measurement unit 502. The microcomputer 510 performs statistical processing on the 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.

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.

The data transceiver 511 performs processes such as converting digital data output from the microcomputer 510 to analog and modulating the analog data. The data transceiver 511 also performs processes such as demodulating the data signal received by the data transceiver antenna 512 and digitizing the demodulated data.

The data transmission/reception antenna 512 is formed 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.

<1.3 Configuration of first information processing device>
Fig. 5 is a diagram showing an example of a functional configuration of the first information processing device 300. As shown in Fig. 5, the first information processing device 300 performs the functions of a communication unit 301, a storage unit 302, and a control unit 303.

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

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 regarding the state of the transmitter 100 and the receiver 200.

The spatial information table 3021 is a table that stores information about the space to be measured. Details will be described later.

The measurement result table 3022 is a table that stores information about the measurement results. Details will be described later.

The control unit 303 is realized by the processor reading a program stored in the memory unit and executing instructions contained in the program. By operating according to the program, the control unit 303 performs the functions shown as a reception control module 3031, a transmission control module 3032, a memory module 3033, a generation module 3034, and a proposal module 3035.

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.

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.

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

The generation module 3034 generates a distribution map in the space of the measurement target based on information related to the measurement of the electric field strength. Specifically, for example, the generation module 3034 refers to 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 is calculated by the measuring device 500, the generation module 3034 may generate a distribution map of the power.

Furthermore, the generation module 3034 generates a floor map (space map) of the space to be measured based on information related to the position measurement by the position measurement unit 504 of the measuring device 500. Specifically, for example, based on information on the position to which the measuring device 500 has moved, such as coordinates, the range on the plane in which the measuring device 500 can move and the range on the plane in which it cannot move are identified, and the movable range 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 height information.

The proposal module 3035 calculates the placement of the transmitter 100 suitable for the space based on the distribution map in the space. The proposal module 3035 may calculate the optimal placement of the transmitter 100 by considering not only the change in the position of the transmitter 100 but also, for example, the increase or decrease in the number of transmitters 100. The proposal module 3035 may calculate the optimal placement of the transmitter 100 while changing not only the placement of the transmitter 100 but also parameters such as the direction in which the transmitter 100 is placed and the strength of the radio waves emitted. For example, the proposal module 3035 estimates the relationship between the electric field and the transmitter 100 based on the calculated distribution map, and adjusts the number, position, and parameters of the transmitter 100 so that the electric field strength in the space is in a recommended state. Furthermore, the proposal module 3035 may perform a predetermined authentication of the transmitter 100, specifically, authentication that certain conditions are met, based on the measurement result of the electric field strength, and output the result.

<3 Data Structure>
6 and 7 are diagrams showing data structures of tables stored in the first information processing device 300. Note that Fig. 6 and Fig. 7 are merely examples and do not exclude data that is not listed. In addition, data that is listed in the same table may be stored in separate storage areas in the storage unit 302.

FIG. 6 is a schematic diagram showing an example of the data structure of the spatial information table 3021 stored in the first information processing device 300. The spatial information table 3021 shown in FIG. 6 is, for example, a table having columns of spatial ID, setting date and time, spatial information, transmitter, receiver, and measuring device, with the setting ID as a key. 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.

The setting ID is an item that stores the identification information of the setting. The space ID is an item that stores the identification information of the space. The setting date and time is an item that stores the date and time when the information about the space is set. The space information is an item that stores the information registered about the 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 material that forms the space, information about the object placed in the space, information about the loss of radio wave intensity in the space, or at least any combination of these. The information about the material that forms the space includes, for example, the floor material, the ceiling material, the wall material, the window glass material, or at least any combination of these. The information about the object placed in the space includes, for example, the position of the object such as a desk and a chair, the type of the object, the material of the object, 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 may be absent, or information other than the above may be included.

The measurement result table 3022 shown in Figure 7 is a table having columns for measurement date and time, electric field strength, and coordinates, for example, with the setting ID as a key.

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

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

Figure 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 arranged in a room, for example, 10 m in the x direction and 10 m in the y direction. Transmitters 100 are arranged, for example, at intervals of 3 m. Measuring device 500 is arranged, for example, so that its position in the y direction is aligned with transmitter 100 and its position in the x direction is between transmitters 100.

In step S11, the measuring device 500 moves within the space in which the WPT system 1 is used under the control of the drive control unit 509.

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

In addition, in step S12, the measuring device 500 performs statistical processing on the measured electric field strength. Specifically, the microcomputer 510 calculates the electric field strength for one second based on the electric field strength measured during, for example, one second. More specifically, the microcomputer 510 calculates the electric field strength for one second by, for example, taking the average of the electric field strengths measured during one second. Also, the microcomputer 510 determines, for example, the peak value of the electric field strength measured during one second as the electric field strength for that one second. The period related to the statistical processing is not limited to one second and may be longer than one second.

In step S13, the measuring device 500 measures the position of the measuring device 500 (measurement unit 54) in the space in which the WPT system 1 is used at the timing when the electric field intensity was measured in step S12. The measurement of the position may be shorter than the period when the electric field intensity was measured. Also, in step S13, the measuring device 500 may measure 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 at the timing when the electric field intensity was measured in step S12 or at another timing. Furthermore, in step S13, the measuring device 500 may photograph the space in which the WPT system 1 is used at the timing when the electric field intensity was measured in step S12 or at another timing.

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

In step S15, the measuring device 500 transmits the processed information to the first information processing device 300. Specifically, the microcomputer 510 transmits the information on which the statistical processing has been performed to the first information processing device 300 at a predetermined cycle. The predetermined cycle may be the same as the period related to the statistical processing, or may be longer than the period. The microcomputer 510 may transmit the average value and the 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 the peak value of the electric field strength to the first information processing device 300. The microcomputer 510 may transmit the measurement result on which the statistical processing has not been performed to the first information processing device 300.

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 first information processing device 300 receives a request for specific information from the second information processing device 400, it executes processing according to the request. For example, when the second information processing device 400 requests the electric field intensity distribution in space, the generation module 3034 generates a distribution diagram in the space of the measurement target based on the information related to the measurement stored in the measurement result table 3022.

Figure 10 is a schematic diagram showing an example of a distribution map generated by the generation module 3034. In Figure 10, the space is divided into a predetermined grid, and the color of the grid indicates 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, the measurement results related to the environment of the space may also be output. At this time, the input of a predetermined condition, for example, a condition of having an electric field strength equal to or higher than a predetermined value, a condition of the electric field strength of the predetermined position information, etc., may be accepted, and only the grids that meet the accepted condition may be output.

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.

For example, when a request for a change in the electric field strength distribution based on a change in the situation in the space or a change in the layout is received from the second information processing device 400, the generation module 3034 refers to the spatial information table 3021 and acquires the date and time when the settings related to the space were updated. The generation module 3034 acquires information related to measurements before and after the update based on the measurement result table 3022, and generates a distribution diagram of the electric field strength based on the acquired information.

For example, when the second information processing device 400 requests a proposal for improving the distribution of the 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.

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

Figure 12 is a schematic diagram showing an example of a distribution map when transmitters 100 are placed as shown in Figure 11. In Figure 12, grids 31 and 32 have low electric field strength compared to 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 in a recommended state. The proposal module 3035 proposes placing the transmitter 100 between grids 31 and 32 in Figure 12, i.e., at (x, y) = (6, 3).

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 space to be measured and transmits a power supply signal. The receiver 200 generates power by the power supply signal. The measuring device 500 is configured to be movable in the space to be measured, measures the electric field strength at the position each time it moves, and measures its position using a position sensor. The first information processing device 300 generates an electric field strength distribution in the space to be measured based on the electric field strength measured by the measuring device 500 and the position information. At this time, the first information processing device 300 may generate an electric field strength distribution in the space to be measured based on the electric field strength measured by the measuring device 500 and the space information stored in advance. This enables the first information processing device 300 to acquire the electric field strength in the space in real time.

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

In addition, in the above embodiment, the measuring device 500 performs measurements related to the environment of the space to be measured and outputs the results in association with the measurement results of the electric field strength. This makes it possible to grasp the strength of the radio waves according to the conditions of the indoor space.

In addition, in the above embodiment, the measuring device 500 captures the space to be measured and outputs the captured image in association with the measurement results of the electric field strength. This makes it possible to grasp the strength of the radio waves according to the conditions of the indoor space.

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

In addition, 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. This makes it possible to grasp the electric field strength that matches the predetermined condition.

<Modification>
In the above embodiment, the case where the first information processing device 300 generates the electric field intensity distribution has been described as an example. However, the measuring device 500 may generate the electric field intensity distribution. In this case, for example, at least one of the measuring devices 500 collects information related to measurement from the other measuring devices 500. The measuring device 500 that has collected the information generates an electric field intensity distribution or a power distribution based on the collected information.

In addition, in each of the above-mentioned embodiments, the application to the so-called WPT system 1 in which the transmission power consisting of an AC signal is wirelessly transmitted from the transmitter 100 to the receiver 200 has been described, but it is naturally possible to apply it to a system that provides power to the receiver 200 by other methods. Since such systems are known, detailed explanations will be omitted, but examples include a system that transmits power generated by solar power generation to the receiver 200 regardless of whether it is wired or wireless, and a system that transmits power to the receiver 200 by laser light regardless of whether it is wired or wireless. In addition, it is also applicable to a configuration in which vibration or sound is given to the receiver 200 and the receiver 200 converts the power of the vibration, etc. into power. In addition, it is naturally applicable to a system that uses a known non-contact power supply technology other than wireless reception of transmission power consisting of an AC signal, such as a non-contact power supply technology using a magnetic field coupling method.
