[0009] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In all the drawings explaining the embodiment, the same reference numerals are given to common components, and repeated explanations are omitted. Note that the following embodiment does not unduly limit the contents of the present disclosure described in the claims. In addition, not all of the components shown in the embodiment are essential components of the present disclosure. In addition, each figure is a schematic diagram and is not necessarily illustrated strictly.

[0010] <Summary> In a WPT (Wireless Power Transfer) system, there are one or more transmitters that transmit a power supply signal and multiple receivers that receive the power supply signal. An information processing device simulates the intensity of power generated in a receiver assumed to be located at an arbitrary position in space by the power supply signal transmitted by one or more transmitters.

[0011] <1 Overall system configuration> FIG. 1 is a diagram showing the overall configuration of a WPT system 1 according to this embodiment.

[0012] 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 third information processing device 500. The WPT system 1 shown in FIG. 1 is used, for example, in a building, a factory, or the like. A building is an example of a structure, and is not limited to a building as long as it is an indoor space where a predetermined activity such as business or office work is 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. The third information processing device 500 may be connected to the first information processing device 300 by wire or wireless. The third information processing device 500 may be connected to the second information processing device 400 by wire or wireless.

[0013] 1 shows an example in which the WPT system 1 includes three transmitters 100, but the number of transmitters 100 included in the WPT system 1 is not limited to three. The number of transmitters 100 included in the WPT system 1 may be two or less, or may be four or more.

[0014] 1 shows an example in which the WPT system 1 includes seven receivers 200, but the number of receivers 200 included in the WPT system 1 is not limited to seven. The number of receivers 200 included in the WPT system 1 may be six or less, or eight or more.

[0015] 1 shows an example in which the WPT system 1 includes two first information processing devices 300, but the number of first information processing devices 300 included in the WPT system 1 is not limited to two. The number of first information processing devices 300 included in the WPT system 1 may be one, or three or more.

[0016] The transmitter 100 transmits, for example, a power supply signal or a data signal to the receiver 200. The transmitter 100 transmits the power supply signal to the receiver 200 by radio waves in the 920 MHz band, for example. The transmitter 100 transmits the data signal to the receiver 200 by radio waves in the 2.4 GHz band, for example. The transmitter 100 may transmit the data signal by radio waves in the 920 MHz band.

[0017] The transmitter 100 may transmit a power supply signal to one receiver 200, for example, or may transmit a power supply signal to multiple receivers 200. The transmitter 100 may transmit a data signal to one receiver 200, for example, or may transmit a data signal to multiple receivers 200. The transmitter 100 may transmit the same data signal as another transmitter 100, for example, or may transmit a data signal different from that of the other transmitters 100. The transmitter 100 may transmit a predetermined command signal as a data signal to the receiver 200, for example, or may transmit a preset signal as a data signal to the receiver 200.

[0018] The transmitter 100 receives, for example, a data signal transmitted from the receiver 200. The transmitter 100 may receive, for example, a data signal transmitted from one receiver 200, or may receive data signals transmitted from a plurality of receivers 200. The transmitter 100 transmits the data signal transmitted from the receiver 200 to the first information processing device 300. The transmitter 100 transmits information related to the state of the transmitter 100 to the first information processing device 300.

[0019] 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, 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, if 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.

[0020] The receiver 200 transmits, for example, information relating to the state of the receiver 200 or information relating to the measurement results of a sensor to the transmitter 100 as a data signal.

[0021] The first information processing device 300 is an information processing device that monitors the operation of the transmitter 100 and the receiver 200 housed in the WPT system 1. For example, the first information processing device 300 determines whether the transmitter 100 or the receiver 200 is in a preset state based on information about the state of the transmitter 100 and the receiver 200 transmitted from the transmitter 100. If it is determined that the transmitter 100 or the receiver 200 is in a preset state, the first information processing device 300 transmits predetermined information to the second information processing device 400.

[0022] 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 information about 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.

[0023] Moreover, 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.

[0024] In addition, the first information processing device 300 controls the operation of the second information processing device 400 .

[0025] The second information processing device 400 is, for example, an information processing device operated by an administrator of the WPT system 1. When the second information processing device 400 receives a notification from the first information processing device 300 that the transmitter 100, the receiver 200, or both of them housed in the WPT system 1 are in a predetermined state, the second information processing device 400 presents to the user that the transmitter 100, the receiver 200, or both of them are in the predetermined state.

[0026] 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 placement of transmitter 100 Information regarding the placement of the receiver 200 Power consumption information Power intensity information

[0027] The third information processing device 500 is, for example, an information processing device operated by a user who is considering introducing the WPT system 1. The third information processing device 500 can be rephrased as, for example, an information processing device operated by a user who is considering constructing the WPT system 1. The third information processing device 500 simulates, for example, a power environment that can be supplied in an indoor space. Specifically, for example, the third information processing device 500 simulates the intensity of power generated in the receiver 200 by a power supply signal transmitted by the transmitter 100 in a space in which the WPT system 1 is constructed. The third information processing device 500 does not need to be an independent information processing device. The function of the third information processing device 500 may be possessed by, for example, the second information processing device 400.

[0028] <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 fixedly installed at a predetermined high position provided in a high place indoors, for example, on a ceiling or a wall. The position of the transmitter 100 can be changed 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 position of the receiver 200 can be changed 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.

[0029] The transmitter 100 includes, for example, an oscillator 101, a transmitting antenna 102, a microcomputer (controller) 103, a data transceiver 104, and a data transmitting / receiving antenna 105. The oscillator 101, the microcomputer 103, the data transceiver 104, and the data transmitting / receiving antenna 105, or at least any combination of these, may be mounted on, for example, a PCB (printed circuit board).

[0030] The oscillator 101 oscillates a signal in a predetermined frequency band, for example, the 920 MHz band. The oscillated signal may be amplified and unnecessary frequency components may be removed, if necessary.

[0031] The transmitting antenna 102 is formed so as to be capable of efficiently transmitting radio waves in the 920 MHz band, for example. The transmitting antenna 102 radiates a signal modulated by a modulator 107 as a power supply signal.

[0032] The microcomputer 103 controls the operation of the transmitter 100. The microcomputer 103 is realized by, for example, a single board computer equipped with an ARM processor. The microcomputer 103 controls, for example, the transmission of radio waves by the transmission antenna 102.

[0033] The data transceiver 104 performs processes such as converting digital data to analog data, modulating analog data, etc. The data transceiver 104 also performs processes such as demodulating a data signal received by the data transceiver antenna 105, and digitizing the demodulated data. For example, the data transceiver 104 extracts a predetermined signal from the data signal received by the data transceiver antenna 105, converts it into digital data, and transmits it to the microcomputer 103.

[0034] The data transmission / reception antenna 105 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 105 radiates a data signal supplied from the data transceiver 104. In addition, the data transmission / reception antenna 105 receives a data signal transmitted from the receiver 200.

[0035] The receiver 200 includes, for example, a receiving antenna 201, a rectifier 202, a power management unit 203, a power storage unit 204, a microcomputer 205, a data transceiver 206, and a data transmitting / receiving antenna 207. The receiving antenna 201, the rectifier 202, the power management unit 203, the power storage unit 204, the microcomputer 205, the data transceiver 206, and the data transmitting / receiving antenna 207, or at least any combination of these, may be mounted on, for example, a PCB or an FPC (flexible printed circuit board).

[0036] The receiving antenna 201 is formed so as 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.

[0037] The rectifier 202 rectifies the radio waves received as a power supply signal and converts them into a DC voltage.

[0038] The power management unit 203 manages the DC voltage. For example, the power management unit 203 controls a charging voltage based on the DC voltage. The power management unit 203 charges the power storage unit 204 by controlling the charging voltage. 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.

[0039] Further, the power management unit 203 releases the power stored in the power storage unit 204 in response to control from the microcomputer 205 .

[0040] The power storage unit 204 stores power in response to an instruction from the power management unit 203. The power storage unit 204 is realized by, for example, a battery or a capacitor. Furthermore, the power storage unit 204 releases the stored power in response to an instruction from the power management unit 203.

[0041] The microcomputer 205 controls the operation of the receiver 200. The microcomputer 205 is driven by a DC voltage supplied from the power management unit 203 or by power stored in the power storage unit 204. The microcomputer 205 controls the power management unit 203 to cause the power storage unit 204 to release the power stored therein.

[0042] 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, and the like are connected to the receiver 200. The sensors connected to the receiver 200 are driven by, for example, a direct current voltage supplied from the power management unit 203 or power discharged from the power storage unit 204. The microcomputer 205 continuously or intermittently monitors the voltage value at a predetermined portion of the receiver 200, the status of the sensor connected to the receiver 200, information detected by the sensor, and the like. The microcomputer 205 transmits the voltage value at a predetermined portion of the receiver 200, the status of the sensor connected to the receiver 200, information detected by the sensor, and the like as digital data to the data transceiver 206. The sensor may be built into the receiver 200.

[0043] The data transceiver 206 performs processes such as converting digital data supplied from the microcomputer 205 into analog data and modulating the analog data. The data transceiver 206 also performs processes such as demodulating a data signal received by a data transceiver antenna 207 and digitizing the demodulated data. The data transceiver 206 is driven by, for example, a DC voltage supplied from the power management unit 203 or power discharged from the power storage unit 204.

[0044] 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. In addition, the data transmission / reception antenna 207 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 power discharged from the power storage unit 204.

[0045] <1.2 Configuration of the third information processing device> Fig. 3 is a block diagram showing a configuration example of the third information processing device 500 shown in Fig. 1. As shown in Fig. 3, the third information processing device 500 includes a communication unit 520, an input device 53, an output device 54, an audio processing unit 57, a microphone 571, a speaker 572, a camera 560, a position information sensor 550, a storage unit 580, and a control unit 590. The blocks included in the third information processing device 500 are electrically connected by, for example, a bus or the like.

[0046] The communication unit 520 performs processing such as modulation and demodulation processing for the third information processing device 500 to communicate with other devices. The communication unit 520 performs transmission processing on a signal generated by the control unit 590 and transmits the signal to the outside (for example, the first information processing device 300). The communication unit 520 performs reception processing on a signal received from the outside and outputs the signal to the control unit 590.

[0047] The input device 53 is a device for a user who operates the third information processing device 500 to input instructions or information. The input device 53 is realized, for example, by a touch-sensitive device 531 or the like in which an instruction is input by touching an operation surface. In the case where the third information processing device 500 is a PC or the like, the input device 53 may be realized by a reader, a keyboard, a mouse, or the like. The input device 53 converts an instruction input by a user into an electric signal, and outputs the electric signal to the control unit 590. Note that the input device 53 may include, for example, a receiving port that receives an electric signal input from an external input device.

[0048] The output device 54 is a device for presenting information to a user who operates the third information processing device 500. The output device 54 is realized, for example, by a display 541 or the like. The display 541 displays data according to the control of the control unit 590. The display 541 is realized, for example, by an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display or the like.

[0049] The audio processing unit 57 performs, for example, digital-analog conversion processing of an audio signal.

The audio processing unit 57 also provides the audio signal to a speaker 572. The audio processing unit 57 is realized, for example, by a processor for audio processing. The microphone 571 accepts audio input and provides an audio signal corresponding to the audio input to the audio processing unit 57. The speaker 572 converts the audio signal provided from the audio processing unit 57 into audio and outputs the audio to the outside of the third information processing device 500.

[0050] Camera 560 is a device for receiving light with a light receiving element and outputting the received light as an imaging signal.

[0051] The position information sensor 550 is a sensor that detects the position of the third information processing device 500, and is, for example, a GPS (Global Positioning System) module. The GPS module is a receiving device used in a satellite positioning system. In the satellite positioning system, signals are received from at least three or four satellites, and the current position of the third information processing device 500 in which the GPS module is mounted is detected based on the received signals. The position information sensor 550 may detect the current position of the third information processing device 500 from the position of a wireless base station to which the third information processing device 500 is connected.

[0052] The storage unit 580 is realized by, for example, the memory 55 and the storage 56, and stores data and programs used by the third information processing device 500. The storage unit 580 stores, for example, condition information 581, rectifier information 582, and application information 583.

[0053] The condition information 581 includes, for example, information on conditions related to the WPT system 1. Specifically, for example, the condition information 581 includes information on conditions of devices that construct the WPT system 1. The information on the device conditions includes, for example, information on the positions of the transmitters 100 arranged in the space related to the WPT system 1. The information on the positions of the transmitters 100 includes, for example, the arrangement intervals of the transmitters 100. The information on the device conditions includes, for example, information on the arrangement of the transmitters 100 in the space related to the WPT system 1. The information on the device conditions includes, for example, information on the number of transmitters 100 arranged in the space related to the WPT system 1. The information on the device conditions includes, for example, information on the transmitter 100. The information on the transmitter 100 includes, for example, information on the strength (transmission power) of the radio wave transmitted by the transmitter 100. The information on the transmitter 100 includes, for example, information on the efficiency of the transmitting antenna 102 of the transmitter 100 (antenna gain of the transmitting antenna 102). The information on the efficiency of the transmitting antenna 102 is affected by, for example, the beam shape, the polarization plane, and the like. The information about the transmitter 100 may include, for example, information about the height at which the transmitter 100 is installed.

[0054] The information on the device condition includes, for example, information on the receiver 200. The information on the receiver 200 includes, for example, information on the efficiency of the receiving antenna 201 of the receiver 200 (antenna gain of the receiving antenna 201). The information on the efficiency of the receiving antenna 201 is affected by, for example, the beam shape, the polarization plane, etc. The information on the receiver 200 includes, for example, information on the efficiency of the rectifier 202 of the receiver 200.

[0055] The information about receiver 200 may include, for example, information about the moving range of receiver 200. The information about receiver 200 may include, for example, information about the installation conditions of receiver 200. Receiver 200 may be affected by, for example, the directivity of radio waves. In such a case, the reception performance differs depending on the position where receiver 200 is installed (or placed). In other words, the reception performance differs depending on whether receiver 200 is placed vertically or horizontally. The information about receiver 200 may include, for example, a parameter that can take into account the difference in reception performance due to the installation mode of receiver 200.

[0056] The information on the device conditions may be stored in advance or may be set by the user. The information on the device conditions is not limited to the above. For example, any of the above may be omitted, or information other than the above may be included.

The information on the environmental conditions includes, for example, information on objects placed in the space. The information on objects placed in the space includes, for example, the positions of objects such as desks and chairs, the types of objects, the materials of objects, or at least any combination of these. The information on the environmental conditions may be stored in advance or may be set by the user. The information on the environmental conditions is not limited to these. For example, any of the above may be absent, or information other than the above may be included.

[0058] The condition information 581 also includes information regarding the loss of radio wave strength in space. The loss of radio wave strength can be expressed as power transmission efficiency. The loss of radio wave strength may be a preset value, or may vary based on the environmental conditions of the space in which the WPT system 1 is constructed.

[0059] The rectifier information 582 includes information related to the efficiency of the rectifier 202. For example, the efficiency of the rectifier 202 varies depending on the strength of the power supply signal received by the receiver 200 and the size of the load connected to the receiver 200 (the size of the load of the application executed by the power generated by the receiver 200). The rectifier information 582 stores, for example, the relationship between the power of the power supply signal supplied to the receiver 200, the size of the load connected to the receiver 200, and the efficiency of the rectifier 202. Details will be described later.

[0060] The application information 583 includes information about the application that is powered by the power generated by the power supply signal, as will be described in detail later.

[0061] The control unit 590 is realized by the processor reading a program stored in the storage unit 580 and executing instructions included in the program.

For example, the operation acceptance unit 591 acquires instructions from the user by analyzing the received voice signal and extracting a predetermined noun.

[0064] The transmission / reception unit 592 performs processing for the third information processing device 500 to transmit and receive data to and from external devices such as the first information processing device 300 and the second information processing device 400 in accordance with a communication protocol. Specifically, for example, the transmission / reception unit 592 transmits an instruction input by a user to the first information processing device 300 or the second information processing device 400. In addition, the transmission / reception unit 592 receives information provided from the first information processing device 300 or the second information processing device 400.

[0065] The first calculation unit 593 calculates the intensity of the power generated by the receiver 200 placed at a predetermined position in a predetermined space in which the WPT system 1 is constructed, due to the power supply signal transmitted from the transmitter 100.

[0066] Specifically, for example, the first calculation unit 593 calculates the intensity of the power generated by the receiver 200 placed at a predetermined position based on the conditions related to the WPT system 1. More specifically, for example, the first calculation unit 593 calculates the intensity of the power generated by the receiver 200 placed at a predetermined position based on the information related to the device conditions and the loss of radio wave intensity in space.

[0067] More specifically, the first calculation unit 593 calculates the intensity of the power generated by the receiver 200 placed at a predetermined position based on information on the positions of one or more transmitters 100 placed in the space related to the WPT system 1, information on the number of transmitters 100 to be placed, information on the intensity (transmission power) of the radio waves transmitted from the transmitter 100, information on the efficiency of the transmission antenna 102 of the transmitter 100, information on the efficiency of the receiving antenna 201 of the receiver 200 assumed to be placed at a predetermined position, and information on the efficiency of the rectifier 202 of the receiver 200. In other words, the first calculation unit 593 calculates the intensity of the power generated by the receiver 200 when the radio waves transmitted from one or more transmitters arrive at the receiver 200 placed at a predetermined position while attenuating. The first calculation unit 593 calculates the intensity of the power in each region obtained by dividing the space into a predetermined size. There is no limitation on how the space is divided, and the shape may be a mesh or another shape.

[0068] The calculation of the power intensity by the first calculation unit 593 is expressed by an equation, for example, as follows. Σ(0~N)_Pout=Σ(0~N)_(Pin*E_air(N)*E_TxAnt*E_RxAnt*E_rect) (1)

[0069] In formula (1), the number of transmitters 100 to be arranged is N, the strength of the radio waves transmitted from the transmitters 100 (transmission power) is Pin, the efficiency of the transmitting antenna 102 of the transmitter 100 is E_TxAnt, the efficiency of the receiving antenna 201 of the receiver 200 is E_RxAnt, the efficiency of the rectifier 202 of the receiver 200 is E_rect, and the radio wave loss in space is E_air(N). The first calculation unit 593 calculates the power strength using formula (1) in each region obtained by dividing the space into a predetermined size.

[0070] The efficiency E_rect of the rectifier 202 of the receiver 200 may be set in advance, may be set by a user, or may be derived based on a predetermined parameter. The first calculation unit 593 derives the efficiency of the rectifier 202, for example, by checking the strength of a power supply signal transmitted from one or more transmitters 100 and arriving at the receiver 200 and the magnitude of the load of an application executed by the power generated by the receiver 200 against the rectifier information 582. The first calculation unit 593 uses the derived efficiency of the rectifier 202 to calculate the strength of the power generated by the receiver 200, for example, by equation (1).

[0071] The loss of radio wave strength in the space may be affected by the environmental conditions in the space in which the WPT system 1 is constructed. The first calculation unit 593 reflects information on the environmental conditions in the loss of radio wave strength in the space. The first calculation unit 593 calculates the strength of the power generated by the receiver 200 placed at a predetermined position based on the information on the device conditions and the loss reflecting the environmental conditions.

[0072] The presentation control unit 594 controls the output device 54 to present the calculated information to the user. Specifically, for example, the presentation control unit 594 causes the display 541 to display the calculated power intensity in each area obtained by dividing the space into a predetermined size. The presentation control unit 594 also causes the display 541 to display the calculated power intensity in each area by superimposing it on the corresponding position on the floor map.

[0073] The presentation control unit 594 causes the display 541 to display available applications (heat sensor, temperature sensor, light sensor, humidity sensor, vibration sensor, etc.) using the power intensity calculated in each area.

[0074] <2 Data Structure> 4 and 5 are diagrams showing data structures of tables stored in the third information processing device 500. Note that Fig. 4 and Fig. 5 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 580.

[0075] Fig. 4 is a schematic diagram showing an example of a data structure of rectifier information 582 stored in the third information processing device 500. The rectifier information 582 shown in Fig. 4 is, for example, a table having columns of efficiency, received power, and load with efficiency No. as a key. The rectifier information 582 shown in Fig. 4 is a table showing the relationship between efficiency and received power and load.

[0076] The efficiency No. is an item that stores a number for identifying the efficiency. The efficiency is an item that stores the efficiency of the rectifier 202. The received power is an item that stores the strength of the power supply signal received by the receiver 200. The load is an item that stores the load of an application executed by the receiver 200.

[0077] Fig. 5 is a schematic diagram showing an example of a data structure of application information 583 stored in the third information processing device 500. The application information 583 shown in Fig. 5 is, for example, a table having columns of application name, function, and load with an application ID as a key.

[0078] The application ID is an item that stores identification information of an application. The application name is an item that stores the name of an application. The function is an item that stores the function of an application. The item "function" stores, for example, any one of a heat sensor, a temperature sensor, a light sensor, a humidity sensor, a vibration sensor, etc. The load is an item that stores the load of an application executed by the receiver 200.

[0079] <3 operations> FIG. 6 is a flowchart showing an example of the operation of the third information processing device 500 when a simulation regarding the arrangement of the transmitters 100 is performed.

[0080] FIG. 7 is a schematic diagram showing an example of a simulation process performed by the third information processing device 500. As shown in FIG.

[0081] In step S11, the third information processing device 500 acquires information on conditions related to the WPT system 1 from the user. Specifically, the control unit 590 of the third information processing device 500 causes the presentation control unit 594 to display an input form for inputting conditions on the display 541. The user operates the input device 53 to input necessary information. The operation receiving unit 591 receives the information input by the user.

[0082] FIG. 8 is a schematic diagram showing a display example of an input form for information on conditions. In the example shown in FIG. 8, a first area 5411 for receiving input of information on space is displayed. In the first area 5411, for example, the x length of the room, the y length of the room, and the length of the interval between the rooms are received. In addition, in the example shown in FIG. 8, a second area 5412 for receiving input of the number and arrangement of the transmitters 100 is displayed. In addition, in the example shown in FIG. 8, a third area 5413 for displaying the set parameters is displayed. In the third area 5413, for example, the settings are "the height of the transmitter is 2.4 m, the height of the receiver is 0.5 m, the transmission efficiency is 40%, the transmission gain is 2 dBi, the reception gain is 2 dBi, and the transmission power is 30 dBm". Note that the information written in the third area 5413 may be variable according to a user's instruction.

[0083] 8, an indicator 5414 for creating a diagram showing the arrangement of the transmitters 100 in a space is displayed. When information about the space is received from the first area 5411, an input of the number and arrangement of the transmitters 100 is received from the second area 5412, and an instruction for the indicator 5414 is received from the user, the presentation control unit 594 creates a diagram showing the arrangement of the transmitters 100 in the space based on the input information. The presentation control unit 594 causes the created diagram to be displayed on the display 541.

[0084] 9 is a diagram illustrating an example of the spatial arrangement of transmitters 100. A user can intuitively grasp the arrangement of transmitters 100 by referring to the diagram illustrating the arrangement of transmitters 100.

[0085] In step S12, the third information processing device 500 receives an instruction to start a simulation from the user. Specifically, in the example shown in Fig. 8, an indicator 5415 for starting a simulation regarding the arrangement of the transmitters 100 is displayed. The user inputs information regarding the space in the first area 5411, inputs the number and arrangement of the transmitters 100 in the second area 5412, and then presses the indicator 5415. The operation receiving unit 591 receives the pressing of the indicator 5415 as an instruction to start the simulation.

[0086] In step S13, the third information processing device 500 calculates the intensity of power generated by the receiver 200 arranged at a predetermined position by the power supply signal transmitted from the transmitter 100. Specifically, for example, the control unit 590 causes the first calculation unit 593 to simulate transmission of radio waves from the transmitters 100 arranged in the input number at the positions input in the area 5412 to the space input in the area 5411. The first calculation unit 593 calculates the intensity of power generated by the receivers 200 arranged in each area divided into a predetermined size in the space by the radio waves transmitted from the transmitter 100 based on other parameters set in advance.

[0087] In step S14, the third information processing device 500 presents the simulation result to the user. Specifically, for example, the control unit 590 causes the presentation control unit 594 to display on the display 541 the power intensity calculated in each area obtained by dividing the space into a predetermined size.

[0088] FIG. 10 is a diagram showing an example of a simulation result of the intensity of the power generated by the receiver 200 arranged at a predetermined position. In the example shown in FIG. 10, the presentation control unit 594 displays the power intensity calculated for each area into which the space in which the WPT system 1 is constructed is divided in a lattice shape in association with the corresponding area. Also, in the example shown in FIG. 10, the presentation control unit 594 displays each area divided in a lattice shape in a manner according to the calculated power intensity. For example, the presentation control unit 594 displays it with hatching of a density according to the height of the power intensity. The manner may be, for example, a color, a pattern, or a combination thereof.

[0089] 10 shows a case where the calculated power intensity is displayed in association with a corresponding grid-like area in space, and a mode corresponding to the power intensity is applied. The presentation control unit 594 may superimpose the power intensity on the floor map, and apply a mode corresponding to the power intensity. Specifically, the presentation control unit 594 divides the floor map into predetermined areas. The presentation control unit 594 associates each divided area in the floor map with the power intensity calculated for each area. The presentation control unit 594 applies a mode corresponding to the associated power intensity to each divided area in the floor map.

[0090] The presentation control unit 594 may also display on the display 541 applications (such as a heat sensor, a temperature sensor, a light sensor, a humidity sensor, a vibration sensor, etc.) that can be used using the power intensity calculated in each region, along with the power intensity, an aspect representing the power intensity, or a combination thereof.

[0091] 6 has been described as to the case where, in step S11, the operation accepting unit 591 accepts input of information about the space, the number of transmitters 100, and the arrangement of the transmitters 100. However, in step S11, the operation accepting unit 591 may accept input other than information about the space, the number of transmitters 100, and the arrangement of the transmitters 100. The operation accepting unit 591 may accept, for example, input of the transmission power of the transmitter 100, the gain of the transmitting antenna 102, the gain of the receiving antenna 201, the efficiency of the rectifier 202, or at least any combination of these.

[0092] In step S13, the first calculation unit 593 calculates the intensity of power generated by the receiver 200 arranged at a predetermined position based on the input information. Specifically, for example, the first calculation unit 593 simulates transmission of radio waves from the input number of transmitters 100 arranged at the positions input in the area 5412 to the space input in the area 5411. The first calculation unit 593 calculates the intensity of power generated by the radio waves transmitted from the transmitter 100 and arranged in each area obtained by dividing the space into a predetermined size based on the input parameters such as the transmission power of the transmitter 100, the gain of the transmitting antenna 102, the gain of the receiving antenna 201, and the efficiency of the rectifier 202.

[0093] In step S11, the operation reception unit 591 may receive input of information on the load of the application executed by the receiver 200 instead of the efficiency of the rectifier 202. In this case, the first calculation unit 593 calculates the strength of the power supply signal received by the receiver 200 in step S13. The first calculation unit 593 compares the calculated strength of the power supply signal and the information on the load of the application with the rectifier information 582, and derives the efficiency of the rectifier 202. The first calculation unit 593 simulates the transmission of radio waves from the transmitters 100 arranged in the input number at the positions input in the area 5412 to the space input in the area 5411. The first calculation unit 593 calculates the strength of the power generated by the receivers 200 arranged in each area divided into a predetermined size by the radio waves transmitted from the transmitter 100, based on the derived parameters such as the efficiency of the rectifier 202. The first calculation unit 593 may calculate the efficiency of the rectifier 202 by substituting the calculated strength of the power supply signal and the load of the application into a predetermined formula for calculating the efficiency of the rectifier 202.

[0094] In addition, in step S11, the operation reception unit 591 may receive input of information on the environmental conditions of the space. In this case, in step S13, the first calculation unit 593 derives the loss of radio wave intensity in the space (power transmission efficiency) based on the information on the environmental conditions. For example, the storage unit 580 stores a predetermined table for deriving the loss. In the table, for example, the materials of members such as the floor, ceiling, and walls in the space are associated with the loss of radio wave intensity. The first calculation unit 593 collates the information on the environmental conditions received as input with the association table to derive the loss of radio wave intensity. The first calculation unit 593 calculates the intensity of the power generated by the radio waves transmitted from the transmitter 100 in the receivers 200 arranged in each area obtained by dividing the space into a predetermined size, based on the derived parameters such as the loss of radio wave intensity. Note that the first calculation unit 593 may calculate the power transmission efficiency by substituting the information on the environmental conditions into a predetermined formula for calculating the power transmission efficiency.

[0095] In step S11, the operation reception unit 591 may receive input of information on obstacles such as desks, chairs, and shelves that may be placed in the space. In this case, in step S13, the first calculation unit 593 derives the loss of radio wave intensity in the space (power transmission efficiency) based on the information on the obstacle. For example, when an obstacle exists on the path from the transmitter 100 to the receiver 200, the first calculation unit 593 reduces the power transmission efficiency to a predetermined value. Based on the derived parameters such as the loss of radio wave intensity, the first calculation unit 593 calculates the intensity of power generated by the radio wave transmitted from the transmitter 100 at the receiver 200 placed in each area obtained by dividing the space into a predetermined size. The first calculation unit 593 may calculate the power transmission efficiency by substituting the information on the obstacle into a predetermined formula for calculating the power transmission efficiency. In step S14, the presentation control unit 594 causes the display 541 to display the calculated power intensity in each area obtained by dividing the space into a predetermined size together with an image related to the obstacle.

[0096] As described above, in the above embodiment, the operation reception unit 591 acquires information about the transmitter 100 that is arranged in a predetermined space and transmits a power supply signal by emitting radio waves. The first calculation unit 593 calculates the intensity of power generated by the receiver 200 that receives the power supply signal at multiple positions in the space based on the information about the transmitter 100. The presentation control unit 594 presents a distribution of the calculated power intensities. This makes it possible to simulate the intensity of power that can be used by the receiver 200 by arranging the transmitter 100.

[0097] Therefore, according to this embodiment, it is possible to assist in determining the placement of a wireless power transmitting device (transmitter) that wirelessly supplies power to a power supply target.

[0098] In the above embodiment, the operation receiving unit 591 acquires information on the power transmission efficiency from the transmitter 100 to a position in space and information on the receiver 200. The first calculation unit 593 calculates the intensity of the power generated by the receiver 200 that receives the power supply signal, based on the information on the transmitter 100, the power transmission efficiency, and the information on the receiver 200. This allows the user to set various parameters, thereby improving the accuracy of the simulation.

[0099] Furthermore, in the above embodiment, the operation reception unit 591 acquires, as information related to the receiver 200, the efficiency of the rectifier 202 that rectifies the received radio waves, based on the intensity of the radio waves received by the receiver 200 and the load related to the receiver 200. This allows the efficiency of the rectifier 202 to be calculated in accordance with the state of the receiver 200, thereby improving the accuracy of the simulation.

[0100] In the above embodiment, the operation receiving unit 591 acquires information about an obstacle placed in the space. The first calculation unit 593 calculates the power intensity based on the information about the obstacle. This makes it possible to simulate the power intensity when an obstacle such as a desk, chair, or shelf is present. This makes it possible to consider the placement of the transmitter 100 in an environment where an obstacle is present.

[0101] <Variation 1> In the above embodiment, the case where the information about the space and the number and arrangement of the transmitters 100 are input from the user has been described as an example, but this information is not limited to being input from the user. For example, the third information processing device 500 may acquire information about a floor map, and set the information about the space and the number and arrangement of the transmitters 100 based on the acquired information about the floor map.

[0102] Fig. 11 is a block diagram illustrating a configuration example of a third information processing device 500 according to Modification 1. In the example illustrated in Fig. 11, a control unit 590 of the third information processing device 500 has an operation receiving unit 591, a transmitting / receiving unit 592, a first calculation unit 593, a presentation control unit 594, and a setting unit 595.

[0103] The setting unit 595 sets information about the space, and the number and arrangement of the transmitters 100, based on information about the floor map received by the operation reception unit 591, for example. The floor map is, for example, a plan view showing the space. The plan view includes, for example, information about dimensions and information about obstacles. The floor map can be rephrased as, for example, a diagram expressing a state in which the state of the space can be understood. The information about the floor map may be received by the transmission / reception unit 592. The setting unit 595 acquires information about the space from the information about the floor map. The setting unit 595 arranges the transmitters 100 in the space according to a predetermined rule based on the acquired information about the space. The predetermined rule for arranging the transmitters 100 is, for example, arranging the transmitters 100 in a lattice shape at a predetermined interval. The setting unit 595 sets the information about the space and the information about the arrangement of the transmitters 100 as conditions related to the WPT system 1.

[0104] FIG. 12 is a flowchart showing another example of the operation of the third information processing device 500 when a simulation regarding the arrangement of the transmitters 100 is performed.

[0105] In step S21, the third information processing device 500 acquires information about the floor map from the user. Specifically, the control unit 590 of the third information processing device 500 causes the presentation control unit 594 to display an input form for inputting information about the floor map on the display 541. The user operates the input device 53 to input information about the floor map. The operation reception unit 591 receives the information input by the user. The information about the floor map may be captured by, for example, a scanner or the like, or may be captured by photographing with a camera.

[0106] Fig. 13 is a diagram showing an example of information related to a floor map input by a user. In the example shown in Fig. 13, the common area is excluded from the space to be simulated because it is not necessary to construct a power supply environment for the common area.

[0107] In step S22, the third information processing device 500 receives an instruction to start a simulation from the user. Specifically, for example, the presentation control unit 594 displays an indicator for starting a simulation regarding the arrangement of the transmitters 100 in an input form. After inputting information regarding the floor map, the user presses the indicator. The operation receiving unit 591 receives the pressing of the indicator as an instruction to start the simulation.

[0108] In step S23, the third information processing device 500 determines the placement of the transmitter 100. Specifically, for example, the control unit 590 of the third information processing device 500 acquires information such as the lengths of the x direction and the y direction of the space from the acquired information on the floor map by the setting unit 595. The setting unit 595 places the transmitter 100 in the space according to a predetermined rule based on the acquired information. The setting unit 595 sets the information on the space and the information on the placement of the transmitter 100 as conditions related to the WPT system 1. The presentation control unit 594 may create a diagram showing the placement of the transmitter 100 and present it to the user.

[0109] 14 is a diagram illustrating an example of the spatial arrangement of transmitters 100. A user can intuitively grasp the arrangement of transmitters 100 by referring to the diagram illustrating the arrangement of transmitters 100.

[0110] In step S24, the third information processing device 500 calculates the intensity of power generated by the receiver 200 arranged at a predetermined position by the power supply signal transmitted from the transmitter 100. Specifically, for example, the control unit 590 causes the first calculation unit 593 to simulate the transmission of radio waves from the transmitter 100 arranged according to a predetermined rule to the space recognized based on the floor map. The first calculation unit 593 calculates the intensity of power generated by the receiver 200 arranged in each area divided into a predetermined size in the space by the radio waves transmitted from the transmitter 100 based on other parameters set in advance.

[0111] In step S25, the third information processing device 500 judges whether the intensity of the power generated by the receiver 200 satisfies a predetermined requirement. Specifically, for example, the control unit 590 of the third information processing device 500 judges whether the power intensity calculated for each region in the space by the first calculation unit 593 satisfies a predetermined requirement. The storage unit 580, for example, stores a threshold value for the power intensity for each region. The first calculation unit 593 judges, for example, whether the power intensity calculated for each region exceeds the threshold value set for each region. If the power intensity calculated for each region exceeds the threshold value set for each region (Yes in step S25), the first calculation unit 593 advances the process to step S26. If the power intensity calculated for each region does not exceed the threshold value set for each region (No in step S25), the first calculation unit 593 advances the process to step S27.

[0112] In step S26, the third information processing device 500 presents the simulation result to the user. Specifically, for example, the control unit 590 causes the presentation control unit 594 to display on the display 541 the power intensity calculated in each area obtained by dividing the space into a predetermined size.

[0113] Fig. 15 is a diagram showing an example of a simulation result of the intensity of the power generated by the receiver 200 arranged at a predetermined position. In the example shown in Fig. 15, the presentation control unit 594 displays the power intensity calculated for each area in which the space in which the WPT system 1 is constructed is divided into a lattice shape in association with the corresponding area. Also, in the example shown in Fig. 15, the presentation control unit 594 displays each area divided into a lattice shape in a manner according to the calculated power intensity. For example, the presentation control unit 594 displays it with hatching of a density according to the height of the power intensity.

[0114] The presentation control unit 594 may superimpose the power intensity on the floor map and add a style according to the power intensity.

[0115] Furthermore, the presentation control unit 594 may use the power intensity calculated in each region to cause the display 541 to display available applications together with the power intensity, a form representing the power intensity, or a combination thereof.

[0116] In step S27, the third information processing device 500 determines the placement of the transmitters 100. Specifically, for example, the control unit 590 of the third information processing device 500 determines the placement of the transmitters 100 that generates stronger power than the placement previously determined, based on the information on the floor map acquired by the setting unit 595. Specifically, the setting unit 595, for example, increases the number of transmitters 100 and places the transmitters 100 so that the transmitters 100 are approximately evenly distributed. The setting unit 595 sets the newly determined information on the placement of the transmitters 100 as a condition related to the WPT system 1. After determining the placement of the transmitters 100, the setting unit 595 shifts the process to step S24.

[0117] 12, the case where the operation accepting unit 591 accepts input of information related to the floor map in step S21 has been described. However, in step S21, the operation accepting unit 591 may accept input of information other than information related to the floor map. For example, the operation accepting unit 591 may accept input of the transmission power of the transmitter 100, the gain of the transmitting antenna 102, the gain of the receiving antenna 201, the efficiency of the rectifier 202, or at least any combination of these.

[0118] In step S24, the first calculation unit 593 calculates the intensity of power generated by the receiver 200 arranged at a predetermined position based on the input information. Specifically, for example, the first calculation unit 593 simulates transmission of radio waves from one or more transmitters 100 arranged in a space based on information related to a floor map. The first calculation unit 593 calculates the intensity of power generated by the radio waves transmitted from the transmitter 100 and the receiver 200 arranged in each area divided into a predetermined size in the space based on input parameters such as the transmission power of the transmitter 100, the gain of the transmitting antenna 102, the gain of the receiving antenna 201, and the efficiency of the rectifier 202.

[0119] In step S21, the operation reception unit 591 may receive input of information on the load of the application executed by the receiver 200 instead of the efficiency of the rectifier 202. In this case, the first calculation unit 593 calculates the strength of the power supply signal received by the receiver 200 in step S24. The first calculation unit 593 compares the calculated strength of the power supply signal and the information on the load of the application with the rectifier information 582, and derives the efficiency of the rectifier 202. The first calculation unit 593 simulates the transmission of radio waves from one or more transmitters 100 arranged in a space based on the information on the floor map. The first calculation unit 593 calculates the strength of power generated by the receiver 200 arranged in each area divided into a predetermined size in the space by the radio waves transmitted from the transmitter 100, based on the derived parameters such as the efficiency of the rectifier 202.

[0120] Also, in step S21, the operation receiving unit 591 may receive input of information on the environmental conditions of the space. In this case, in step S24, the first calculation unit 593 derives the loss of radio wave intensity in the space (power transmission efficiency) based on the information on the environmental conditions. For example, the storage unit 580 stores a predetermined table for deriving the loss. For example, the table associates the materials of the members such as the floor, ceiling, and walls in the space with the loss of radio wave intensity. The first calculation unit 593 collates the information on the environmental conditions received as input with the association table to derive the loss of radio wave intensity. The first calculation unit 593 calculates the intensity of the power generated by the radio waves transmitted from the transmitter 100 in the receivers 200 arranged in each area divided into a predetermined size in the space based on the derived parameters such as the loss of radio wave intensity.

[0121] In step S21, the operation reception unit 591 may acquire information on obstacles such as desks, chairs, and shelves arranged in the space based on information on the floor map. In this case, in step S24, the first calculation unit 593 derives the loss of radio wave intensity in the space (power transmission efficiency) based on information on the obstacle. For example, when an obstacle exists on the path from the transmitter 100 to the receiver 200, the first calculation unit 593 reduces the power transmission efficiency to a predetermined value. Based on parameters such as the derived loss of radio wave intensity, the first calculation unit 593 calculates the intensity of power generated by the radio wave transmitted from the transmitter 100 at the receiver 200 arranged in each area obtained by dividing the space into a predetermined size. In step S26, the presentation control unit 594 causes the display 541 to display the calculated power intensity in each area obtained by dividing the space into a predetermined size together with an image related to the obstacle.

[0122] As described above, in the above embodiment, the operation receiving unit 591 acquires information about a diagram (floor plan) expressing the state of the space. The setting unit 595 sets the number of transmitters to be placed and the positions at which the transmitters are placed as information about the transmitters, based on the acquired information about the diagram. This allows the user to simulate the power intensity by simply inputting the floor plan, without having to input the number and placement of the transmitters themselves.

[0123] In the above embodiment, the process is repeated until the calculated power intensity for a preset area in space satisfies a preset requirement. This makes it possible to avoid a situation where the power is insufficient even when the position of the transmitter 100 is determined based on a diagram that represents the state of the space.

[0124] <Variation 2> In the above embodiment, the case where the arrangement of the transmitters 100 in a space is determined, and the strength of the power generated by the receivers 200 arranged in each area divided into a predetermined size by the radio waves transmitted from the arranged transmitters 100 is calculated is described as an example. However, it is not limited to determining the arrangement of the transmitters 100 first. For example, the third information processing device 500 may estimate the power required by a desired application, and determine the number and arrangement of the transmitters 100 capable of supplying the estimated power.

[0125] Fig. 16 is a block diagram illustrating a configuration example of a third information processing device 500 according to Modification 2. In the example illustrated in Fig. 16, a control unit 590 of the third information processing device 500 has an operation receiving unit 591, a transmitting / receiving unit 592, a second calculation unit 596, and a presentation control unit 594.

[0126] The second calculation unit 596 arranges the transmitter 100 in a predetermined space in which the WPT system 1 is constructed so as to generate power that can be used by an application desired by the user. Specifically, the second calculation unit 596 calculates, for example, a power distribution that can be used by an application desired by the user. The second calculation unit 596 determines the arrangement of the transmitter 100 in the space in which the WPT system 1 is constructed so as to satisfy, for example, a power distribution that can be used by the desired application.

[0127] The presentation control unit 594 controls the output device 54 to present the results of the simulation to the user. Specifically, for example, the presentation control unit 594 causes the display 541 to display the arrangement of the transmitters 100 capable of using a desired application. The presentation control unit 594 also causes the display 541 to display the intensity distribution of power generated in the receiver 200 arranged at a predetermined position by a power supply signal transmitted from the arranged transmitter 100.

[0128] FIG. 17 is a flowchart showing another example of the operation of the third information processing device 500 when a simulation regarding the arrangement of the transmitters 100 is performed.

[0129] In step S31, the third information processing device 500 acquires information about the application from the user. Specifically, the control unit 590 of the third information processing device 500 causes the presentation control unit 594 to display an input form for inputting information about the space and information about the application on the display 541. The user operates the input device 53 to input information about the space, and information about the position and type of the application desired to be used in the space. The operation reception unit 591 receives the information input by the user.

[0130] Fig. 18 is a schematic diagram showing a display example of an input form for information about an application. In the example shown in Fig. 18, an area 5416 for receiving a selection of an application is displayed. The user selects an icon representing a desired application from area 5416 and places it in a desired position in space for use.

[0131] In step S32, the third information processing device 500 receives an instruction to start a simulation from the user. Specifically, in the example shown in Fig. 18, an indicator 5418 for starting a simulation regarding the arrangement of the transmitters 100 is displayed. The user selects an application from the area 5416, arranges the application in the space, and then presses the indicator 5418. The operation receiving unit 591 receives the pressing of the indicator 5418 as an instruction to start the simulation.

[0132] In step S33, the third information processing device 500 calculates a power distribution in which the user can use the application desired by the user. Specifically, the control unit 590 of the third information processing device 500 causes the second calculation unit 596 to read out the load of the application selected by the user from the application information 583. The second calculation unit 596 calculates a power distribution in which the desired application can be used based on the position where the application selected by the user is located and the load of the application selected by the user.

[0133] In step S34, the third information processing device 500 determines the placement of the transmitters 100 in the space in which the WPT system 1 is constructed. Specifically, the control unit 590 causes the second calculation unit 596 to place the transmitters 100 in the space in accordance with a predetermined rule based on the information about the space input by the user. The predetermined rule for placing the transmitters 100 is, for example, placing the transmitters 100 in a lattice shape at a predetermined interval. The information about the space may be extracted by analyzing information about a floor map, etc.

[0134] In step S35, the third information processing device 500 calculates the intensity of power generated by the receiver 200 arranged at a predetermined position by the power supply signal transmitted from the transmitter 100. Specifically, for example, the control unit 590 causes the second calculation unit 596 to simulate the transmission of radio waves from the transmitter 100 arranged according to a predetermined rule to the space recognized based on the floor map. The second calculation unit 596 calculates the intensity of power generated by the receiver 200 arranged in each area divided into a predetermined size in the space by the radio waves transmitted from the transmitter 100 based on other parameters set in advance.

[0135] In step S36, the third information processing device 500 judges whether the power intensity generated by the receiver 200 satisfies the power intensity at which the application can be used. Specifically, for example, the control unit 590 judges whether the power intensity calculated for each area in the space by the second calculation unit 596 satisfies the power intensity at which the application desired by the user can be used. If the power intensity calculated for each area satisfies the power intensity at which the application desired by the user can be used (Yes in step S36), the second calculation unit 596 advances the process to step S37. If the power intensity calculated for each area does not satisfy the power intensity at which the application desired by the user can be used (No in step S36), the second calculation unit 596 advances the process to step S38.

[0136] In step S37, the third information processing device 500 presents the simulation result to the user. Specifically, for example, the control unit 590 causes the presentation control unit 594 to display on the display 541 the arrangement of the transmitters 100 capable of using a desired application. In addition, the presentation control unit 594 causes the display 541 to display the intensity distribution of the power generated in the receiver 200 arranged at a predetermined position by the power supply signal transmitted from the arranged transmitter 100.

[0137] FIG. 19 is a diagram showing an example of a simulation result of the arrangement of the transmitters 100. In FIG.

[0138] The presentation control unit 594 may superimpose the simulation result of the arrangement of the transmitters 100 on the floor map.

[0139] In step S38, the third information processing device 500 determines the placement of the transmitters 100. Specifically, for example, the control unit 590 of the third information processing device 500 determines, by the second calculation unit 596, a placement of the transmitters 100 in which the intensity of the generated power is stronger than that of the placement determined previously, based on the information on the space input by the user. Specifically, the second calculation unit 596, for example, increases the number of the transmitters 100 and places the transmitters 100 so that the transmitters 100 are approximately evenly distributed. After determining the placement of the transmitters 100, the second calculation unit 596 shifts the process to step S35.

[0140] 17, the case where the operation receiving unit 591 receives an input of information related to an application in step S31 has been described. However, in step S31, the operation receiving unit 591 may receive an input other than information related to an application. For example, the operation receiving unit 591 may receive an input of the transmission power of the transmitter 100, the gain of the transmitting antenna 102, the gain of the receiving antenna 201, the efficiency of the rectifier 202, or at least any combination of these.

[0141] In step S35, the second calculation unit 596 calculates the intensity of the power generated by the receiver 200 arranged at a predetermined position based on the input information. Specifically, for example, the second calculation unit 596 simulates the transmission of radio waves from one or more transmitters 100 arranged in a space. The second calculation unit 596 calculates the intensity of the power generated by the radio waves transmitted from the transmitter 100 and generated by the receiver 200 arranged in each area divided into a predetermined size in the space based on the input parameters such as the transmission power of the transmitter 100, the gain of the transmitting antenna 102, the gain of the receiving antenna 201, and the efficiency of the rectifier 202.

[0142] In addition, in step S31, the operation reception unit 591 may not receive an input regarding the efficiency of the rectifier 202. In this case, in step S35, the second calculation unit 596 calculates the strength of the power supply signal received by the receiver 200. The second calculation unit 596 compares the calculated strength of the power supply signal and information regarding the load of the application with the rectifier information 582, and derives the efficiency of the rectifier 202. The second calculation unit 596 simulates the transmission of radio waves from one or more transmitters 100 arranged in a space. Based on the derived parameters such as the efficiency of the rectifier 202, the second calculation unit 596 calculates the strength of the power generated by the receiver 200 arranged in each area divided into a predetermined size in the space by the radio waves transmitted from the transmitter 100.

[0143] In step S31, the operation reception unit 591 may receive input of information on the environmental conditions of the space. In this case, in step S35, the second calculation unit 596 derives the loss of radio wave intensity in the space (power transmission efficiency) based on the information on the environmental conditions. For example, the storage unit 580 stores a predetermined table for deriving the loss. For example, the table associates the materials of the members such as the floor, ceiling, and walls in the space with the loss of radio wave intensity. The second calculation unit 596 compares the information on the environmental conditions received as input with the association table to derive the loss of radio wave intensity. The second calculation unit 596 calculates the intensity of the power generated by the radio waves transmitted from the transmitter 100 in the receivers 200 arranged in each area divided into a predetermined size in the space based on the derived parameters such as the loss of radio wave intensity.

[0144] In step S31, the operation reception unit 591 may receive input of information on obstacles such as desks, chairs, and shelves that may be placed in the space. In this case, in step S35, the second calculation unit 596 derives the loss of radio wave intensity in the space (power transmission efficiency) based on the information on the obstacle. For example, when an obstacle exists on the path from the transmitter 100 to the receiver 200, the second calculation unit 596 reduces the power transmission efficiency to a predetermined value. Based on the derived parameters such as the loss of radio wave intensity, the second calculation unit 596 calculates the intensity of power generated by the radio wave transmitted from the transmitter 100 at the receiver 200 placed in each area obtained by dividing the space into a predetermined size. The second calculation unit 596 may calculate the power transmission efficiency by substituting the information on the obstacle into a predetermined formula for calculating the power transmission efficiency. In step S37, the presentation control unit 594 causes the display 541 to display the calculated power intensity in each area obtained by dividing the space into a predetermined size together with an image related to the obstacle.

[0145] Furthermore, the third information processing device 500 may repeat the calculation of the placement of the transmitter 100 and the strength of the power generated by the receiver 200 until the strength of the power generated by the receiver 200 satisfies a predetermined requirement.

[0146] As described above, in the above embodiment, the operation receiving unit 591 acquires information about space, information about the position where the application is used, and information about the load of the application. The second calculation unit 596 determines the position of the transmitter 100 that supplies power usable for the application by radio waves based on the acquired information about the position and information about the load. The presentation control unit 594 presents the determined position of the transmitter 100. This makes it possible to simulate the number and positions of transmitters required based on the application desired to be used.

[0147] Therefore, according to this embodiment, it is possible to assist in determining the placement of a wireless power transmitting device (transmitter) that wirelessly supplies power to a power supply target.

[0148] In the above embodiment, the operation receiving unit 591 acquires information on the power transmission efficiency from the transmitter 100 to a position in space and on the receiver 200 that receives the power supply signal. The second calculation unit 596 determines the position of the transmitter 100 based on the information on the position, the information on the load, the power transmission efficiency, and the information on the receiver 200. This allows the user to set various parameters, thereby improving the accuracy of the simulation.

[0149] Furthermore, in the above embodiment, the operation reception unit 591 acquires the efficiency of the rectifier 202 that rectifies the received radio waves as information related to the receiver 200, based on the intensity of the radio waves received by the receiver 200 and the load of the application. This allows the efficiency of the rectifier 202 to be calculated according to the state of the receiver 200, thereby improving the accuracy of the simulation.

[0150] In the above embodiment, the operation receiving unit 591 acquires information about an obstacle placed in the space. The second calculation unit 596 determines the position of the transmitter 100 based on the information about the obstacle. This makes it possible to simulate the intensity of the power when an obstacle such as a desk, chair, or shelf is present. This makes it possible to consider the placement of the transmitter 100 in an environment where an obstacle is present.

[0151] In the above embodiment, the second calculator 596 repeats the determination of the transmitter position until the power generated by the power supply signal in a preset region in space satisfies a preset requirement. This makes it possible to avoid the occurrence of a region with insufficient power even when the position of the transmitter 100 is determined based on a desired application.

[0152] In the above embodiment, the case where the intensity distribution of the power generated by the power supply signal is expressed in two dimensions has been described. However, the third information processing device 500 is not limited to expressing the intensity distribution of the power in two dimensions. The third information processing device 500 may express the distribution of the power intensity in three dimensions by simulating the power intensity distribution at the heights of multiple layers. In this case, the third information processing device 500 may express the distribution of the power intensity at multiple heights in two dimensions.
