Embodiments for Carrying Out the Invention
[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In all the drawings for describing the embodiments, common components are denoted by the same reference numerals, and repeated descriptions are omitted. Note that the following embodiments do not unduly limit the content of the present disclosure described in the claims. Also, not all of the components shown in the embodiments are essential components of the present disclosure. Also, each figure is a schematic diagram and is not necessarily drawn precisely.
[0011] <Overview> In a WPT (Wireless Power Transfer) system, there are one or more transmitters that transmit a power supply signal and a plurality of receivers that receive the power supply signal. One or more measuring instruments measure the electric field strength based on the power supply signal transmitted by the transmitter. The information processing device calculates the electric field strength distribution in the measurement target space (indoor space) based on the electric field strength measured by the measuring instrument.
[0012] <1 Configuration of the Entire System> FIG. 1 is a diagram showing the overall configuration of the WPT system 1 according to the present 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 instrument 500. The WPT system 1 shown in FIG. 1 is used, for example, in a building or a factory. The building is an example of a building and is not limited to a building as long as it is an indoor space where predetermined activities such as business and work are performed. 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] In FIG. 1, an example in which the WPT system 1 includes three transmitters 100 is shown, 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] In FIG. 1, an example in which the WPT system 1 includes seven receivers 200 is shown, 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 may be eight or more.
[0016] Note that in this specification, the transmitter 100 is a (power) transmitter in the sense of wirelessly transmitting power, and similarly, the receiver 200 is a (power) receiver in the sense of wirelessly receiving power. As will be described later, the receiver 200 may transmit information regarding the state of the receiver 200 or information regarding the measurement result 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 a data signal, and the receiver 200 functions as a transmitter that transmits a data signal.
[0017] In FIG. 1, an example is shown in which the WPT system 1 includes two measuring devices 500. However, 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 may be three or more. The measuring device 500 is provided, for example, so as to be movable within the space where the WPT system 1 is used.
[0018] In FIG. 1, an example is shown in which the WPT system 1 includes two first information processing devices 300. However, 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 may be 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 a power supply signal to the receiver 200, for example, by radio waves in the 920 MHz band. The transmitter 100 transmits a data signal to the receiver 200, for example, by radio waves in the 2.4 GHz band. The transmitter 100 may transmit a data signal by radio waves in the 920 MHz band.
[0020] The transmitter 100 may supply power to, for example, one receiver 200, or may supply power to a plurality of receivers 200. The transmitter 100 may transmit a data signal to, for example, one receiver 200, or may transmit a data signal to a plurality of receivers 200. The transmitter 100 may transmit, for example, the same data signal as another transmitter 100, or may transmit a data signal different from another transmitter 100. The transmitter 100 may transmit, for example, 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 regarding 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. For example, when the receiver has a power storage unit, the receiver 200 converts the power supply signal transmitted from the transmitter 100 into electric power and stores the converted electric power in the power storage unit. For example, when the receiver 200 has a predetermined sensor, the receiver 200 converts the power supply signal transmitted from the transmitter 100 into electric power and drives the sensor with the converted electric power. The receiver 200 may drive the sensor with the electric power stored in the power storage unit.
[0023] The receiver 200 transmits, for example, information regarding the state of the receiver 200 or information regarding the measurement result by the sensor to the transmitter 100 as a data signal.
[0024] The measuring instrument 500 measures, for example, the intensity of the electric field (electric field intensity) generated by the power supply signal transmitted from the transmitter 100. The measuring instrument 500 measures, for example, the intensity along the three axes in the rectangular coordinate system of the electric field generated by the radio wave in the 920 MHz band transmitted from the transmitter 100. The measuring instrument 500 performs, for example, a predetermined statistical process on the measured electric field intensity. The measuring instrument 500 transmits the processed information to the first information processing device 300 by radio waves in the 2.4 GHz band, for example.
[0025] In addition, the measuring device 500 measures, for example, the position of the measuring device 500 within the space where the WPT system 1 is used. The measuring device 500 measures the position (coordinates) along the three axes in the orthogonal coordinate system within the space where the WPT system 1 is used. The measuring device 500 measures its own position by, for example, the triangulation technique, which is a known technique, using the respective positions of the known transmitters 100 and the radio waves in the 920 MHz band transmitted from the transmitters 100. However, it may also measure its own position by other techniques such as RFID (Radio Frequency Identification) and GPS (Global Positioning System).
[0026] In addition, the measuring device 500 performs measurements related to the environment of the space where the WPT system 1 is used. As measurements related to the environment of the space where the WPT system 1 is used, the measuring device 500 measures, for example, the temperature, humidity, illuminance, carbon dioxide concentration, atmospheric pressure, etc. of the space.
[0027] Furthermore, the measuring device 500 performs imaging of the space where 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. The measuring device 500 calculates, for example, the intensity along the three axes in the orthogonal coordinate system of the power that can be generated by the radio waves in the 920 MHz band transmitted from the transmitter 100. The measuring device 500 performs, for example, predetermined statistical processing on the calculated power. The measuring device 500 transmits the processed information to the first information processing device 300 by radio waves in the 2.4 GHz band, for example.
[0029] The first information processing device 300 is an information processing device that monitors the operations of the transmitter 100 and the receiver 200 accommodated in the WPT system 1. For example, based on the information regarding the states of the transmitter 100 and the receiver 200 transmitted from the transmitter 100, the first information processing device 300 determines whether the transmitter 100 or the receiver 200 is in a preset state. If it is determined that the device is in the preset state, the first information processing device 300 transmits predetermined information to the second information processing device 400.
[0030] In addition, 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 the information regarding the states 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.
[0031] In addition, the first information processing device 300 controls the operation of the transmitter 100 accommodated in the WPT system 1. For example, the first information processing device 300 transmits a predetermined instruction or information to the transmitter 100.
[0032] In addition, the first information processing device 300 controls the operation of the second information processing device 400.
[0033] In addition, the first information processing device 300 monitors the radio wave environment of the space in which the WPT system 1 is constructed. The first information processing device 300 stores, for example, the 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, for example, the distribution of the electric field strength in the space based on the stored information and the information regarding the arrangement 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 calculates, for example, the appropriate arrangement 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 the administrator of the WPT system 1. When the second information processing device 400 receives from the first information processing device 300 a communication indicating that the transmitter 100, the receiver 200, or both of them accommodated in the WPT system 1 are in a predetermined state, the second information processing device 400 presents to the user that the transmitter 100, the receiver 200, or both of them are in the predetermined state.
[0035] In addition, the second information processing device 400 analyzes information regarding the states 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, as follows. · Information regarding the arrangement of the transmitter 100 · Information regarding the arrangement of the receiver 200 · Information regarding power consumption · Information regarding electric field strength
[0036] In addition, the second information processing device 400 analyzes 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, as follows. · Electric field strength distribution in the space · Temporal change of the electric field strength distribution in the space · Change of the electric field strength distribution based on a change in the situation in the space (for example, arrangement of the transmitter 100 or change of parameters) · Change of the electric field strength distribution based on a change in the layout in the space (for example, change of the arrangement of desks, shelves, etc.) · Optimal arrangement of the transmitter 100 (for example, if not calculated by the first information processing device 300)
[0037] <1.1 Configuration of Transmitter and Receiver> FIG. 2 is a block diagram showing a configuration example 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 separated from each other at a predetermined interval, for example. 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 fixedly installed at a predetermined high position provided on a high place indoors, for example, on the ceiling or a wall. Depending on the installation method, the transmitter 100 can be repositioned after installation. The receiver 200 is installed on a predetermined device indoors or placed near a device that requires power supply. Further, the receiver 200 may be carried by a user. Depending on the installation method, the receiver 200 can be repositioned after installation. The transmitter 100 transmits a power supply signal to the receiver 200 by radio waves of a predetermined frequency, for example, in the 920 MHz band. The receiver 200 converts the power supply signal transmitted from the transmitter 100 into electric power, and charges the converted electric power or supplies the converted electric power to a predetermined device.
[0038] The transmitter 100 includes, for example, an oscillator 101, a transmission antenna 102, a microcomputer (controller) 103, a data transceiver 104, and a data transceiver antenna 105. The oscillator 101, the microcomputer 103, the data transceiver 104, the data transceiver antenna 105, or at least any combination thereof may be mounted on a PCB (printed circuit board), for example.
[0039] The oscillator 101 oscillates a signal in a predetermined frequency band, for example, in the 920 MHz band. The oscillated signal may be amplified and unnecessary frequency components may be removed as necessary.
[0040] The transmission antenna 102 is formed to be able to efficiently transmit radio waves in the 920 MHz band, for example. The transmission antenna 102 radiates the signal modulated by the modulator 107 as a power supply signal.
[0041] The microcontroller 103 controls the operation of the transmitter 100. The microcontroller 103 is realized by, for example, a semiconductor element equipped with an ARM processor. The microcontroller 103 controls, for example, the transmission of radio waves by the transmission antenna 102.
[0042] The data transceiver 104 performs processes such as analog conversion of digital data and modulation of analog data. Further, the data transceiver 104 performs processes such as demodulation of the data signal received by the data transmission / reception antenna 105 and digital conversion of the demodulated data. The data transceiver 104 extracts, for example, a predetermined signal from the data signal received by the data transmission / reception antenna 105, converts it into digital data, and transmits it to the microcontroller 103.
[0043] The data transmission / reception antenna 105 is formed, for example, so as to be able to efficiently transmit and receive radio waves in the 2.4 GHz band. The data transmission / reception antenna 105 radiates the data signal supplied from the data transceiver 104. Further, the data transmission / reception antenna 105 receives the data signal transmitted from the receiver 200.
[0044] The receiver 200 includes, for example, a reception antenna 201, a rectifier 202, a power management unit 203, a power storage unit 204, a microcontroller 205, a data transceiver 206, and a data transmission / reception antenna 207. The reception antenna 201, the rectifier 202, the power management unit 203, the power storage unit 204, the microcontroller 205, the data transceiver 206, the data transmission / reception antenna 207, or at least any combination thereof may be mounted on, for example, a PCB or an FPC (flexible printed circuit board).
[0045] The reception antenna 201 is formed, for example, so as to be able to efficiently receive radio waves in the 920 MHz band. The reception antenna 201 receives the power supply signal radiated from the transmission antenna 102.
[0046] The rectifier 202 rectifies the radio wave received as the power supply signal and converts it into a DC voltage.
[0047] 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. By controlling the charging voltage, the power management unit 203 charges the power storage unit 204. Also, when, for example, the power storage unit 204 stores power exceeding a predetermined capacity, the power management unit 203 supplies the DC voltage to the connected members.
[0048] Also, the power management unit 203 discharges the power stored in the power storage unit 204 in response to the 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, a capacitor, or the like. Also, the power storage unit 204 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 the DC voltage supplied from the power management unit 203 or the power stored in the power storage unit 204. The microcomputer 205 controls the power management unit 203 to discharge the power stored in the power storage unit 204.
[0051] For example, various sensors can be connected to the receiver 200. For example, a thermal 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 by, for example, the DC voltage supplied from the power management unit 203 or the power discharged from the power storage unit 204. The microcomputer 205 continuously or intermittently monitors the voltage value at a predetermined part of the receiver 200, the status of the sensors connected to the receiver 200, the information detected by the sensors, etc. The microcomputer 205 transmits the voltage value at a predetermined part of the receiver 200, the status of the sensors connected to the receiver 200, the information detected by the sensors, etc. to the data transceiver 206 as digital data. Note that the sensors may be built into the receiver 200.
[0052] The data transceiver 206 performs processes such as analog conversion of digital data supplied from the microcomputer 205 and modulation of analog data. Further, the data transceiver 206 performs processes such as demodulation of a data signal received by the data transmission / reception antenna 207 and digitization of the demodulated data. The data transceiver 206 is driven by, for example, a DC voltage supplied from the power management unit 203 or power released from the power storage unit 204.
[0053] The data transmission / reception antenna 207 is formed, for example, to be capable of efficiently transmitting and receiving radio waves in the 2.4 GHz band. The data transmission / reception antenna 207 radiates a data signal supplied from the data transceiver 206. Further, the data transmission / reception antenna 207 receives the data signal transmitted from the transmitter 100. For example, the data transmission / reception antenna 207 is driven by, for example, a DC voltage supplied from the power management unit 203 or power released from the power storage unit 204.
[0054] <1.2 Configuration of the measuring instrument> FIG. 3 is a perspective view showing an appearance and a configuration example of the measuring instrument 500 shown in FIG. 1. The measuring instrument 500 shown in FIG. 3 is arranged in a space to be measured, such as a space where the WPT system 1 is used. The measuring instrument 500 is composed of, for example, a housing 51, a telescopic part 52, an insulating part 53, and a measuring part 54.
[0055] The housing 51 is the main body part of the measuring instrument 500 and is realized by, for example, a resin such as polyvinyl chloride, and has a disk shape as shown in FIG. 3. In FIG. 3, an example where the shape of the housing 51 is disk-shaped is shown, but it is not limited to such a shape. On the lower surface side (not shown) of the housing 51, for example, tires that can move on the floor surface are attached, and it is configured to be able to move freely on the plane indicated by the arrow XY in FIG. 3, that is, on the floor surface of the space where the WPT system 1 is used.
[0056] The telescopic part 52 is provided so as to protrude from the upper surface of the housing 51, and is a part that supports the insulating part 53 and the measuring part 54. For example, it is realized by a resin such as polyvinyl chloride, and has a long cylindrical shape as shown in FIG. 3. In FIG. 3, an example where the shape of the telescopic part 52 is cylindrical is shown, but it is not limited to such a shape. The telescopic part 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 where the WPT system 1 is used. Further, the telescopic part 52 is configured to be rotatable in the plane direction about a rotation axis centered on the central part of the housing 51 as shown by the arrow R1 in FIG. 3.
[0057] The insulating part 53 is provided on the other end side of the telescopic part 52 extended from the housing 51, and is a part that supports the measuring part 54. For example, it is realized by a material having excellent insulation properties such as polyimide, and has a disk shape as shown in FIG. 3. In FIG. 3, an example where the shape of the insulating part 53 is disk-shaped is shown, but it is not limited to such a shape.
[0058] The measuring part 54 is placed and provided above the insulating part 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 instrument 500, the environment in the space, and a camera for photographing the space are provided. For example, it is covered with a resin such as polyvinyl chloride, and realized by providing a gap for taking in the air in the space and a photographing window for photographing with the camera, and has a disk shape as shown in FIG. 3. In FIG. 3, an example where the shape of the measuring part 54 is disk-shaped is shown, but it is not limited to such a shape.
[0059] The insulating part 53 and the measuring part 54 are configured to be rotatable in a direction inclined with respect to the floor surface of the space where the WPT system 1 is used as shown by the arrow L in FIG. 3. Further, the insulating part 53 and the measuring part 54 are configured to be rotatable about a rotation axis parallel to the floor surface of the space as shown by the arrow R2 in FIG. 3. Note that the insulating part 53 and the measuring part 54 are configured to be rotatable in the same direction as the telescopic part 52 rotates in the direction of the arrow R1.
[0060] FIG. 4 is a block diagram showing a functional configuration example of the measuring device 500 shown in FIG. 1. The measuring device 500 includes, for example, an antenna 501 for electric field measurement, an electric field strength measurement unit 502, an antenna 503 for position measurement, a position measurement unit 504, an environmental measurement sensor 505, an environmental measurement 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 transceiver antenna 512. At least any combination of these may be mounted on, for example, a PCB or an FPC (flexible printed circuit board).
[0061] The antenna 501 for electric field measurement is formed, for example, to efficiently receive radio waves in the 920 MHz band. The antenna 501 for electric field measurement is formed, for example, along three axes in a rectangular coordinate system. That is, the antenna 501 for electric field measurement 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 it may be a monopole antenna. Each antenna element has a length (for example, about 40 mm) corresponding to the wavelength of radio waves in the 920 MHz band. The antenna 501 for electric field measurement receives the power supply signal radiated from the transmission 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 antenna 501 for electric field measurement. Specifically, the electric field strength measurement unit 502 measures the electric field strength and obtains information on the electric field strength based on, for example, the strength of the signal received for each antenna element of the antenna 501 for electric field measurement. That is, the antenna 501 for electric field measurement 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. The predetermined period is, for example, a plurality of times (about 1000 times) per second. The electric field strength measurement unit 502 outputs the measurement result to the microcomputer 510. The measurement result may be attached with a time stamp indicating the time when the measurement was performed.
[0063] The antenna 503 for position measurement has, for example, the same configuration as the antenna 501 for electric field measurement, and is formed, for example, along three axes in a rectangular coordinate system. Note that if the antenna 503 for position measurement can be shared with the antenna 501 for electric field measurement, the function may be realized by the antenna 501 for electric field measurement.
[0064] Based on the signal received by the antenna 503 for position measurement, the position measurement unit 504 measures the position of the measuring device 500 (measurement unit 54) in the space where the WPT system 1 is used and acquires position information. That is, the antenna 503 for position measurement and the position measurement unit 504 constitute a position sensor. Note that the antenna 503 for position measurement and the position measurement unit 504 are not essential components. For example, the movement amount of the measuring device 500 may be measured by the drive control unit 509, and the position information of the measuring device 500 may be acquired.
[0065] The environmental measurement sensor (environmental sensor) 505 is constituted by, for example, sensors for measuring the environment of the space where the WPT system 1 is used, specifically, the temperature, humidity, illuminance, carbon dioxide concentration, atmospheric pressure, etc. of the space.
[0066] Based on the signal detected by the environmental measurement sensor 505, the environmental measurement unit 506 measures the environment of the space where the WPT system 1 is used and acquires environmental information.
[0067] The camera 507 is, for example, a device that receives light by a light receiving element and outputs it as a shooting signal, shoots the space where the WPT system 1 is used, and acquires the captured image information (captured image). Specifically, the camera 507 is constituted by a wireless camera or the like.
[0068] The power storage unit 508 stores, for example, the power supplied from the outside. The power storage unit 508 is realized by, for example, a battery, a capacitor, or the like. Note that the power storage unit 508 may store the power generated by the power supply signal transmitted from the transmitter 100. When the measuring device 500 is arranged connected to the receiver 200, the measuring device 500 may use the power storage unit 204 of the receiver 200. Also, when the measuring device 500 is built in 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 operation of the housing 51 moving within the space where the WPT system 1 is used. The drive control unit 509 controls, for example, the housing 51 to move on the plane indicated by the arrow XY shown in FIG. 3, and controls to avoid obstacles and move when there are obstacles in the traveling direction. The measuring device 500 may be provided with various sensors for realizing such control, but the illustration is omitted.
[0070] The microcomputer 510 controls the operation of the measuring device 500. Also, the microcomputer 510 executes statistical processing based on the measurement results measured by the electric field strength measurement 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 processes can be performed. The predetermined period is, for example, a period corresponding to the cycle in which the measuring device 500 transmits information regarding the measurement results. The predetermined period may be the same as the cycle in which the measuring device 500 transmits information regarding the measurement results, or may be shorter. The microcomputer 510 outputs, as information regarding the measurement results, the information after the statistical processing or the information measured by the electric field strength measurement unit 502 to the data transceiver 511. The microcomputer 510 outputs, for example, the information regarding the measurement results with the date and time when the measurement was performed attached.
[0071] The microcomputer 510 may calculate the generated power on the assumption that the own device is the receiver 200 based on the measurement result measured by the electric field strength measurement unit 502. Specifically, for example, the microcomputer 510 stores information regarding the efficiency of the rectifier. For example, the efficiency of the rectifier varies depending on the intensity 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 regarding the efficiency of the rectifier and the measurement result measured by the electric field strength measurement unit 502. The microcomputer 510 performs statistical processing on the data regarding 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. By pressing the power switch, an input is provided as to whether or not to drive the measuring instrument 500. When the user inputs to turn on the power switch, the microcomputer 510 is driven. When the user inputs to turn off the power switch, the microcomputer 510 stops.
[0073] The data transceiver 511 performs processes such as analog conversion of digital data output from the microcomputer 510 and modulation of analog data. Further, the data transceiver 511 performs processes such as demodulation of a data signal received by the data transmission / reception antenna 512 and digital conversion of the demodulated data.
[0074] 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 a data signal output from the data transceiver 511. Further, the data transmission / reception antenna 512 receives a data signal transmitted from the first information processing device 300.
[0075] <1.3 Configuration of the First Information Processing Device> FIG. 5 is a diagram showing a functional configuration example of the first information processing apparatus 300. As shown in FIG. 5, the first information processing apparatus 300 functions as a communication unit 301, a storage unit 302, and a control unit 303.
[0076] The communication unit 301 performs processes for the first information processing apparatus 300 to communicate with other apparatuses, for example, the transmitter 100, the receiver 200, and the measuring instrument 500.
[0077] The storage unit 302 includes, for example, a space information table 3021, a measurement result table 3022, etc. The tables stored in the storage unit 302 are not limited to these. The storage unit 302 stores, for example, tables for storing information regarding the states of the transmitter 100 and the receiver 200 in addition to these.
[0078] The space information table 3021 is a table for storing information regarding the space to be measured. Details will be described later.
[0079] The measurement result table 3022 is a table for storing information regarding the measurement results. Details will be described later.
[0080] The control unit 303 is realized by a processor reading a program stored in the storage unit and executing instructions included in the program. By operating according to the program, the control unit 303 functions 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 for the first information processing apparatus 300 to receive a signal from other apparatuses, for example, the transmitter 100, the second information processing apparatus 400, and the measuring instrument 500 according to the communication protocol.
[0082] The transmission control module 3032 controls the process for the first information processing apparatus 300 to transmit a signal to other apparatuses, for example, the transmitter 100, the second information processing apparatus 400, and the measuring instrument 500 according to the communication protocol.
[0083] The memory module 3033 stores the information acquired from the transmitter 100 and the measuring device 500 in the memory unit 302. Specifically, for example, information regarding the measurement results is transmitted from the measuring device 500 at a predetermined cycle. The memory module 3033 acquires the 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 in the space to be measured based on the information regarding 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. When the power is calculated by the measuring device 500, the generation module 3034 may generate a distribution map of the power.
[0085] In addition, the generation module 3034 generates a floor map (space map) of the space to be measured based on the information regarding the measurement of the position by the position measurement unit 504 of the measuring device 500. Specifically, for example, based on the information of the position where the measuring device 500 has moved, such as coordinates, the range on the plane where the measuring device 500 can move and the range on the plane where it could not move are specified, and the movable range is mapped as the range of that floor to generate a floor map. Furthermore, the generation module 3034 may generate a three-dimensional map including not only the floor map on the plane but also the information in the height direction.
[0086] The proposal module 3035 calculates the arrangement of the transmitter 100 suitable for the space based on the distribution map in the space. The proposal module 3035 may calculate the optimal arrangement of the transmitter 100 considering not only the change in the position of the transmitter 100 but also, for example, the increase or decrease of the transmitter 100. Further, the proposal module 3035 may calculate the optimal arrangement of the transmitter 100 while changing not only the arrangement of the transmitter 100 but also parameters such as the direction in which the transmitter 100 is arranged and the intensity of the radio wave radiated. The proposal module 3035, for example, estimates the relevance 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 becomes a recommended state. Furthermore, the proposal module 3035 may perform a predetermined authentication for the transmitter 100 based on the measurement result of the electric field strength, specifically, authentication that a certain condition is satisfied, and output the result.
[0087] <3 Data Structure> FIG. 6 and FIG. 7 are diagrams showing the data structure of the tables stored in the first information processing apparatus 300. Note that FIGS. 6 and 7 are examples, and do not exclude data that is not described. Also, even data described in the same table may be stored in separate storage areas in the storage unit 302.
[0088] FIG. 6 is a schematic diagram showing an example of the data structure of the space information table 3021 stored in the first information processing apparatus 300. The space information table 3021 shown in FIG. 6 is a table having columns for space ID, setting date and time, space information, transmitter, receiver, and measuring instrument, for example, with the setting ID as the key. The information stored in the space information table 3021 is, for example, information measured by the position measurement unit 504 of the measuring instrument 500.
[0089] 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 information about the space was set. The space information is an item that stores the information registered about the space. The space information includes, for example, the longitudinal distance of the room, the lateral distance of the room, the height of the room, information about the material forming the space, information about the objects arranged in the space, information about the loss of radio wave intensity in the space, or at least any combination thereof. Information about the material forming the space includes, for example, floor material, ceiling material, wall material, window glass material, or at least any combination thereof. Information about the objects arranged in the space includes, for example, the position of objects such as desks and chairs, the type of objects, the material of the objects, or at least any combination thereof. The space information may be stored in advance or set by the user. The space information is not limited to these. For example, any of the above may not be present, or information other than the above may be included.
[0090] The transmitter is an item that stores information about the transmitter 100. The item "transmitter" includes the coordinates where the transmitter 100 is arranged, the transmission gain, the transmission intensity, or at least any combination thereof. The receiver is an item that stores information about the receiver 200. The item "receiver" includes the coordinates where the receiver 200 is arranged, the reception gain, the rectification efficiency, or at least any combination thereof. The measuring instrument is an item that stores information about the measuring instrument 500. The item "measuring instrument" includes the coordinates where the measuring instrument 500 is arranged, 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 apparatus 300. The measurement result table 3022 shown in FIG. 7 is, for example, a table having columns of measurement date and time, electric field strength, and coordinates, with the setting ID as the key.
[0092] 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. In the item "electric field strength", information that has undergone statistical processing may be stored, or information before statistical processing may be stored. The coordinates are an item that stores the position where the electric field strength was measured.
[0093] <4 Operation> FIG. 8 is a flowchart showing an example of the operation of the measuring device 500. In the description of FIG. 8, a case where the transmitter 100 and the measuring device 500 are arranged as shown in FIG. 9, for example, will be described.
[0094] FIG. 9 is a diagram showing an example of the arrangement of the transmitter 100 and the measuring device 500 in space. The transmitter 100 and the measuring device 500 are arranged, for example, in a room that is 10 m in the x direction and 10 m in the y direction. The transmitters 100 are arranged, for example, at intervals of 3 m. The measuring device 500 is arranged such that, for example, the position in the y direction is aligned with the transmitter 100 and the position in the x direction is located between the transmitters 100.
[0095] In step S11, the measuring device 500 moves within the space where the WPT system 1 is used under the control of the drive control unit 509.
[0096] In step S12, the measuring device 500 measures the electric field strength at a predetermined cycle. Specifically, the electric field measurement antenna 501 receives the radio waves in the 920 MHz band transmitted from the transmitter 100 by the antenna elements 5011, 5012, and 5013 arranged along the three axes in the orthogonal coordinate system. The electric field strength measurement unit 502 measures the electric field strength for each axis, for example, based on the intensity of the radio waves received by the antenna elements 5011, 5012, and 5013 at a cycle of multiple times per second.
[0097] Also, in step S12, the measuring device 500 performs statistical processing on the measured electric field strength. Specifically, the microcomputer 510 calculates, for example, the electric field strength for one second based on the electric field strength measured within 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 within one second. Also, the microcomputer 510 uses, for example, the peak value of the electric field strength measured within one second as the electric 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) within 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 measurement of the position may be shorter than the period for measuring the electric field strength. Also, in step S13, the measuring device 500 may perform measurements regarding the environment of the space where the WPT system 1 is used, specifically measurements of the temperature, humidity, illuminance, carbon dioxide concentration, atmospheric pressure, etc. of the space, at the timing when the electric field strength was measured in step S12 or at other timings. Further, in step S13, the measuring device 500 may perform imaging of the space where the WPT system 1 is used at the timing when the electric field strength was measured in step S12 or at other timings.
[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 the position information where the electric field strength was measured with the electric field strength at that position so that it can grasp the measurement result of the electric field strength for each position in the space where the WPT system 1 is used. At this time, it may also associate with the measurement result regarding the environment of the space.
[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 information subjected to statistical processing to the first information processing device 300 at a predetermined cycle. The predetermined cycle may coincide with the period related to the statistical processing, or may be longer than the said period. The microcomputer 510 may transmit the average value of the electric field strength and the peak value to the first information processing device 300. The microcomputer 510 may transmit the difference between the average value of the electric field strength and the peak value to the first information processing device 300. The microcomputer 510 may transmit the measurement results without performing statistical processing to the first information processing device 300.
[0101] When the first information processing device 300 receives the information related to the measurement from the measuring device 500, it stores the received information in the measurement result table 3022. When, for example, a predetermined information is requested from the second information processing device 400, the first information processing device 300 executes the processing corresponding to the request. For example, when the electric field strength distribution in the space is requested from the second information processing device 400, the generation module 3034 generates a distribution diagram in 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 showing an example of the distribution diagram generated by the generation module 3034. In FIG. 10, the space is divided into predetermined grids, and the electric field strength is represented by the color of the grids. The electric field strength is output based on the position information of the measuring device 500. The division of the grids is set, for example, based on the arrangement of the measuring device 500. The grids may be set by arranging the measuring device 500, or the measuring device 500 may be arranged according to the grids. At this time, the measurement results related to the environment of the space may be output together. Also, at this time, inputs such as predetermined conditions, for example, conditions having an electric field strength equal to or higher than a predetermined value, conditions of the electric field strength of predetermined position information, etc. may be received, and only the grids corresponding to the received conditions may be output.
[0103] Also, for example, when the second information processing device 400 requests a change over time in the electric field strength distribution, the generation module 3034 generates a distribution diagram of the electric field strength at a plurality of time points based on the information related to the measurement stored in the measurement result table 3022.
[0104] Also, for example, when the second information processing device 400 requests a change in the electric field strength distribution based on a change in the situation within the space or a change in the layout, the generation module 3034 refers to 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 related to the 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.
[0105] Also, 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 arrangement of the transmitter 100 suitable for the space based on the distribution diagram within the space.
[0106] FIG. 11 is a diagram showing an example of the arrangement of the transmitter 100 and the measuring instrument 500 in the space. Different from the example shown in FIG. 9, in FIG. 11, the transmitter 100 is not arranged at (x, y) = (6, 3).
[0107] FIG. 12 is a schematic diagram showing an example of the distribution diagram when the transmitter 100 is arranged as shown in FIG. 11. In FIG. 12, the grids 31 and 32 have a lower electric field strength compared to other grids. The proposal module 3035 estimates the relationship 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 within the space becomes a recommended state. The proposal module 3035 proposes to arrange the transmitter 100 between the grids 31 and 32 in FIG. 12, that is, 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, a plurality of measuring instruments 500, and a first information processing device 300. The transmitter 100 is installed in the measurement target space and transmits a power supply signal. The receiver 200 generates electric power by the power supply signal. The measuring instrument 500 is configured to be movable within the measurement target space, measures the electric field strength at its position for each movement, and measures the position by 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 and position information measured by the measuring instrument 500. At this time, the first information processing device 300 may generate an electric field strength distribution within the measurement target space based on the electric field strength measured by the measuring instrument 500 and the space information stored in advance. Thereby, the first information processing device 300 can acquire the electric field strength within the space in real time.
[0109] Therefore, according to the WPT system 1 according to the present embodiment, the intensity of radio waves in the indoor space can be grasped.
[0110] Also, in the above embodiment, the measuring instrument 500 performs measurements related to the environment of the measurement target space and outputs them in association with the measurement results of the electric field strength. Thereby, the intensity of radio waves according to the conditions of the indoor space can be grasped.
[0111] Also, in the above embodiment, the measuring instrument 500 takes a picture of the measurement target space and outputs it in association with the measurement results of the electric field strength. Thereby, the intensity of radio waves according to the situation of the indoor space can be grasped.
[0112] Also, in the above embodiment, the measuring instrument 500 generates a floor map (space map) of the measurement target space. Thereby, even when there is no detailed information about the indoor space, it is possible to grasp the measurement target space and perform measurement of the electric field strength.
[0113] Further, in the above embodiment, the first information processing apparatus 300 outputs information on the electric field strength in a floor map (space map) based on a predetermined condition. Thereby, it becomes possible to grasp the electric field strength that matches the predetermined condition.
[0114] <Modification Example> In the above embodiment, the case where the first information processing apparatus 300 generates an electric field strength distribution has been described as an example. However, the measuring device 500 may generate an electric field strength distribution. In this case, for example, at least one of the plurality of measuring devices 500 collects information regarding measurement from 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] Also, in each of the above-described embodiments, the application to the so-called WPT system 1 in which the transmission power composed of an AC signal is wirelessly transmitted from the transmitter 100 to the receiver 200 has been described. However, 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 description is omitted. As an example, a system that sends power generated by solar power generation to the receiver 200 regardless of whether it is wired or wireless, and further, a system that sends power to the receiver 200 by laser light regardless of whether it is wired or wireless, etc. can be mentioned. In addition, a configuration in which vibration or sound is applied to the receiver 200 and the receiver 200 converts power such as vibration into electric power is also applicable. In addition, it is naturally applicable to a known non-contact power supply technology other than wirelessly receiving transmission power composed of an AC signal, for example, a system using a non-contact power supply technology based on a magnetic field coupling method.
