[0047] <1.1 Transmitter and Receiver Configuration>

[0048] Figure 2 It shows Figure 1 FIG. 1 is a block diagram of a configuration example of a transmitter 100 and a receiver 200. Figure 2As shown, the transmitter 100 and the receiver 200 are spaced apart from each other, for example, at a predetermined distance.

[0066] The microcontroller 205 is configured to control the operation of the receiver 200. The microcontroller 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 microcontroller 205 is configured to control the power management unit 203 to discharge power stored in the power storage unit 204.

[0067] Furthermore, the microcontroller 205 is configured to control a process of associating the transmitter 100 and the receiver 200 with each other. That is, the microcontroller 205 is configured to control pairing between the transmitter 100 and the receiver 200.

[0068] Receiver 200 can be connected to various sensors, for example. For example, a heat sensor, a temperature sensor, a light sensor, a humidity sensor, a vibration sensor, and the like are connected to receiver 200. The sensors connected to receiver 200 are driven by, for example, a DC voltage supplied from power management unit 203 or power discharged from power storage unit 204. Microcontroller 205 is configured to continuously or intermittently monitor the voltage value at a predetermined location on receiver 200, the status of sensors connected to receiver 200, information detected by the sensors, and the like. Microcontroller 205 is configured to transmit the voltage value at a predetermined location on receiver 200, the status of sensors connected to receiver 200, information detected by the sensors, and the like as digital data to data transceiver 206. Note that the sensors may be built into receiver 200.

[0069] The data transceiver 206 is configured to perform processing such as converting digital data supplied from the microcontroller 205 into analog data and modulating the analog data. Furthermore, the data transceiver 206 is configured to perform processing such as demodulating a data signal received by the 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.

[0070] The data transceiver antenna 207 is configured to efficiently transmit and receive radio waves in, for example, the 2.4 GHz band. The data transceiver antenna 207 is configured to radiate the data signal supplied from the data transceiver 206. In addition, the data transceiver antenna 207 is configured to receive the data signal transmitted from the transmitter 100. The data transceiver antenna 207 is driven, for example, by a DC voltage supplied from the power management unit 203 or by power discharged from the power storage unit 204.

[0071] The storage unit 208 is implemented by, for example, a memory, and stores data and programs used by the receiver 200. The storage unit 208 is configured to store, for example, transmitter information 2081 and receiver information 2082. The transmitter information 2081 includes, for example, information about the associated transmitter 100. The information about the associated transmitter 100 includes, for example, identification information of the transmitter 100.

[0072] The receiver information 2082 includes, for example, information about the device itself (receiver). The receiver information includes, for example, identification information of the receiver, information about specifications for transmitting data signals during pairing, and information about thresholds of the power storage unit 204.

[0073] The information regarding the specifications for transmitting data signals during pairing indicates, for example, the frequency channel used to transmit the data signal. For example, the frequency channel is set based on the identification information. Specifically, for example, if the identification ID is an even number, channel 1 is set, and if it is an odd number, channel 2 is set.

[0074] Furthermore, information regarding the specifications for transmitting data signals during pairing indicates, for example, the period for transmitting the data signals. For example, the period is set based on the identification information. Specifically, for example, when the identification ID is an even number, the period is set to 0.7 seconds, and when it is an odd number, the period is set to 0.8 seconds.

[0075] Note that the specifications for the data signal transmitted during pairing are not limited to varying based on whether the identification information is an odd or even number. The specifications may vary for each divisor of a predetermined natural number. Furthermore, information regarding the specifications for the data signal transmitted during pairing is not limited to being based on the identification information of receiver 200 and may be set for each receiver 200.

[0076] Information regarding the threshold value of the power storage unit 204 is used when the receiver 200 responds to the transmitter 100. The threshold value is, for example, a power value at which the receiver 200 can perform pairing processing. This power value is, for example, lower than the power value required for the receiver 200 to operate. The threshold value is, for example, the same value for all receivers 200. The initial value of the power stored in the power storage unit 204 is different for each receiver 200. Therefore, even if the threshold value is set to the same value for each receiver, the time required from the start of charging to reaching the set power value will vary for each receiver 200. On the other hand, the threshold value can be different for each receiver 200. Therefore, regardless of the initial power value, the time required from the start of charging to reaching the set power value will vary for each receiver 200.

[0077] Furthermore, multiple threshold values ​​can be stored. For example, different threshold values ​​can be used for initial pairing and for second and subsequent pairings. For initial pairing, for example, the threshold value is set to a power level lower than the power required for receiver 200 operation. Consequently, operation may be stopped, and there is a possibility that the amount of power stored in power storage unit 204 of receiver 200, the target of second or subsequent pairing, may exceed the threshold value set for initial pairing. Therefore, for second and subsequent pairings, a power level higher than the threshold used for initial pairing is set to the threshold value. Thus, even if pairing is performed after stopping receiver 200 operation, for example, the possibility of stored power exceeding the threshold value can be suppressed.

[0085] <3 Operations during pairing of transmitter and receiver>

[0086] (Example 1)

[0087] Figure 6 This figure is used to explain the operation of transmitter 100 and multiple receivers 200 when pairing transmitter 100 and multiple receivers 200. In Example 1, a case is described where multiple receivers 200 switch from normal operation mode to a first mode and then associate transmitter 100 and receivers 200. Normal operation mode is, for example, a mode in which receiver 200 uses a power signal transmitted from transmitter 100 and performs sensing using a sensor, etc. The first mode is a mode for associating transmitter 100 and receiver 200. For example, in the first mode, sensing and other operations are stopped to associate transmitter 100 and receiver 200.

[0088] In Example 1, for example, receiver 200 may be the first receiver 200 to be paired with transmitter 100. That is, receiver 200 may be the first receiver 200 to be operated before being installed at a predetermined location. In this embodiment, receiver 200 being paired with transmitter 100 for the first time includes, for example, receiver 200 being powered on for the first time, receiver 200 for which the pairing recognition status is not recorded in ROM, and the like. Furthermore, receiver 200 may be the first receiver 200 to be paired with transmitter 100 and installed at a predetermined location, and then needs to be paired again. That is, receiver 200 may be the first receiver 200 to be activated after being installed at a predetermined location.

[0089] When multiple receivers 200 exist within a predetermined range, the administrator of the WPT system 1 instructs the transmitter 100 to start pairing. The instruction to start pairing can be input by pressing a physical button provided on the transmitter 100 or input through the first information processing device 300.

[0090] When pairing begins, in step S11, the microcontroller 103 of the transmitter 100 instructs the multiple receivers 200 to switch to the first mode. Specifically, the microcontroller 103 modulates the power signal, for example, according to a predetermined rule. The microcontroller 103 modulates the power signal with a command signal to switch the receivers 200 to the first mode. More specifically, for example, the microcontroller 103 controls the modulator 107 to amplitude-modulate, frequency-modulate, or phase-modulate the power signal, in response to a command to switch the receivers 200 to the first mode. The transmitting antenna 102 transmits the power signal modulated with the command signal into space. The command to switch to the first mode may consist of, for example, 0s and 1s.

[0091] A plurality of receivers 200 located within a predetermined range from the transmitter 100 are configured to receive the power supply signal radiated from the transmitter 100 .

[0092] In step S12, upon receiving the power supply signal modulated with the command signal, the microcontroller 205 of the receiver 200 switches the mode of the receiver 200 to the first mode. Specifically, the receiving antenna 201 receives the power supply signal modulated with the command signal. The rectifier 202 rectifies the received power supply signal and converts it into a DC voltage. The power management unit 203 controls the charging voltage based on the DC voltage and charges the power storage unit 204.

[0093] For example, a portion of the power supply signal is extracted by a directional coupler (not shown) and sent to the demodulator 209. The demodulator 209 demodulates the extracted signal and generates a command signal modulated onto the power supply signal. The demodulator 209 outputs the command signal to the microcontroller 205. When the microcontroller 205 receives the command signal, it switches the receiver 200 to the first mode.

[0094] In step S13, microcontroller 103 notifies multiple receivers 200 of its identification information. Specifically, for example, microcontroller 103 modulates the power supply signal according to a predetermined rule. For example, when the power supply signal modulated with the command signal satisfies a predetermined condition, microcontroller 103 switches the modulated signal. More specifically, for example, when microcontroller 103 transmits the power supply signal modulated with the command signal within a predetermined time period, it switches the modulated signal. Furthermore, for example, when microcontroller 103 transmits the power supply signal modulated with the command signal a predetermined number of times, it switches the modulated signal.

[0095] Microcontroller 103 modulates the power signal using, for example, the device's identification information. Specifically, for example, microcontroller 103 controls modulator 107 to amplitude-modulate, frequency-modulate, or phase-modulate the power signal, which has a transmitter ID of "1001." Transmitter antenna 102 radiates the power signal, modulated with the identification information, into space.

[0096] The plurality of receivers 200 located within a predetermined range from the transmitter 100 receive the power supply signal radiated from the transmitter 100 .

[0097] In step S14, microcontroller 205 registers transmitter 100. Specifically, receiving antenna 201 receives a power supply signal modulated with the identification information of transmitter 100. Rectifier 202 rectifies the received power supply signal and converts it into a DC voltage. Power management unit 203 controls the charging voltage based on the DC voltage and charges power storage unit 204.

[0098] For example, a portion of the power supply signal is extracted by a directional coupler (not shown) and sent to the demodulator 209. The demodulator 209 demodulates the extracted signal and generates identification information modulated onto the power supply signal. The demodulator 209 outputs the identification information to the microcontroller 205. When the microcontroller 205 receives the identification information, it stores the received identification information in the transmitter information 2081.

[0099] In step S15, the microcontroller 103 causes the transmitting antenna 102 to transmit a power supply signal that is not modulated with a command signal or identification information. For example, when the transmission of the power supply signal modulated with identification information meets a predetermined condition, the microcontroller 103 stops modulating the power supply signal with the identification information. For example, when the microcontroller 103 transmits the power supply signal modulated with identification information within a predetermined time period, the microcontroller 103 stops modulating the power supply signal with the identification information. Furthermore, for example, when the microcontroller 103 transmits the power supply signal modulated with identification information a predetermined number of times, the microcontroller 103 stops modulating the power supply signal with the identification information.

[0100] The plurality of receivers 200 located within a predetermined range from the transmitter 100 receive the power supply signal radiated from the transmitter 100 .

[0101] In step S16, the microcontroller 205 determines whether the amount of electricity charged in the storage unit 204 has reached a predetermined value. Specifically, the receiving antenna 201 receives the power supply signal. The rectifier 202 rectifies the received power supply signal and converts it into a DC voltage. The power management unit 203 controls the charging voltage based on the DC voltage and charges the storage unit 204. The microcontroller 205 determines whether the amount of electricity charged in the storage unit 204 has reached a threshold value stored in the receiver information 2082. For example, at the start of the pairing process, the amount of electricity charged in the storage unit 204 is different for each receiver 200. Therefore, as Figure 6 As shown, the time when the amount of electricity in the power storage unit 204 reaches the threshold value is different for each receiver 200 .

[0102] For example, when multiple thresholds are stored in the receiver information 2082, the microcontroller 205 sets a threshold value based on the number of pairing attempts. For example, if this is the first pairing attempt, the microcontroller 205 sets a low threshold value. Furthermore, if this is the second or subsequent pairing attempts, the microcontroller 205 sets a high threshold value.

[0103] In step S17, when the amount of electricity stored in the power storage unit 204 reaches a threshold, the microcontroller 205 transmits a data signal including the identification information of the receiver 200 to the transmitter 100. Specifically, when the amount of electricity stored in the power storage unit 204 reaches the threshold, the microcontroller 205 reads the device's identification information from the receiver information 2082. The data transceiver 206 modulates a carrier wave using the extracted identification information and converts it into a data signal. The microcontroller 205 reads the identification information of the associated transmitter 100 from the transmitter information 2081 and sets it as the transmission destination. The microcontroller 205 reads the data transmission specifications from the receiver information 2082 and radiates the data signal from the data transceiver antenna 207 toward the transmitter 100 as the destination according to the read specifications.

[0104] For example, when the identification information stored in the receiver information 2082 is an even number, the size stored in the receiver signal 2082 is also an even number, and the predetermined transmission channel and predetermined transmission period corresponding to this situation are available, the microcontroller 205 uses the predetermined transmission channel and predetermined transmission period assigned to the even number to transmit the data signal. Furthermore, for example, when the identification information stored in the receiver information 2082 is an odd number, the size stored in the receiver signal 2082 is also an odd number, and the predetermined transmission channel and predetermined transmission period corresponding to this situation are available, the microcontroller 205 uses the predetermined transmission channel and predetermined transmission period assigned to the odd number to transmit the data signal.

[0105] The transmitter 100 located within a predetermined range from the receiver 200 receives the data signal radiated from the receiver 200 .

[0106] In step S18, the microcontroller 103 registers the receiver 200. Specifically, the data transceiver 104 demodulates the received data signal and acquires the identification information of the receiver 200. The microcontroller 103 stores the acquired identification information in the receiver information 1062.

[0107] If the intended paired receiver 200 is pre-registered in the receiver information 1062, the microcontroller 103 can determine whether pairing is complete based on this information. For example, the microcontroller 103 compares the identification information of the intended paired receiver 200 with the identification information of the newly stored receiver 200. If there is a receiver 200 that does not receive a data signal in response, the microcontroller 103 determines that pairing is not yet complete. The microcontroller 103 then resumes the first mode and continues to radiate the power signal.

[0108] In step S19, the microcontroller 103 instructs the multiple receivers 200 to switch to normal operation mode. Specifically, for example, when there are responses from all predetermined paired receivers 200, the microcontroller 103 causes the receivers 200 to switch from the first mode to the normal operation mode. For example, the microcontroller 103 instructs the receivers 200 to switch to normal operation mode via a data signal. Specifically, the microcontroller 103 modulates a carrier wave with the command instructing the switch to normal operation mode, thereby generating a data signal. The microcontroller 103 reads the identification information of the associated receiver 200 from the receiver information 1062 and sets it as the transmission destination. The microcontroller 103 radiates the data signal from the data transceiver antenna 105 to the destination receiver 200.

[0109] In step S110, when the receiver 200 receives the data signal, the receiver 200 switches from the first mode to the normal operation mode. Thus, the transmitter 100 and the receiver 200 are associated with each other, and the data signal is transmitted and received between the associated transmitter 100 and receiver 200.

[0110] exist Figure 6 In the description of FIG, an example has been described in which the transmitter 100 transmits a power supply signal that is not modulated with a command signal or identification information in step S15. However, the transmitter 100 may continue to transmit a power supply signal that is modulated with identification information without performing the process of step S15.

[0111] (Example 2)

[0112] In Example 1, a case has been described in which the receiver 200 is in the normal operation mode at the start of pairing and switches to the first mode in response to an instruction from the transmitter 100. At the start of pairing, the receiver 200 may be in the first mode.

[0113] Figure 7 is a diagram for explaining another example of operations of the transmitter 100 and the plurality of receivers 200 when the transmitter 100 and the plurality of receivers 200 perform pairing.

[0114] In Example 2, for example, receiver 200 is pairing with transmitter 100 for the first time. In this embodiment, receivers 200 pairing with transmitter 100 for the first time include, for example, receivers 200 being powered on for the first time, receivers 200 whose pairing recognition status is not recorded in ROM, and the like. When multiple receivers 200 are within a predetermined range, the administrator of WPT system 1 instructs transmitter 100 to start pairing. The instruction to start pairing can be input by pressing a physical button on transmitter 100 or by inputting it through first information processing device 300.

[0115] When pairing begins, in step S21, microcontroller 103 notifies multiple receivers 200 of its identification information. Specifically, for example, microcontroller 103 modulates the power signal according to a predetermined rule. Microcontroller 103 modulates the power signal using, for example, the device's own identification information. Specifically, for example, microcontroller 103 controls modulator 107 to amplitude-modulate, frequency-modulate, or phase-modulate the power signal whose transmitter ID is "1001." Transmitting antenna 102 radiates the power signal, modulated with the identification information, into space.

[0116] The plurality of receivers 200 located within a predetermined range from the transmitter 100 receive the power supply signal radiated from the transmitter 100 .

[0117] like Figure 6 In the illustrated example, the transmitter 100 and the receiver 200 are associated with each other through steps S14 to S110. That is, the transmitter 100 and the receiver 200 are paired.

[0118] As described above, in the above embodiment, system 1 includes transmitter 100 and multiple receivers 200. Transmitter 100 transmits a power supply signal. Transmitter 100 receives a data signal including identification information of receiver 200 from receiver 200. Transmitter 100 registers receiver 200 based on the received data signal. Receiver 200 is assigned unique identification information, and when the amount of electricity stored in storage unit 204 due to the power supply signal transmitted from transmitter 100 reaches a predetermined value, receiver 200 transmits a data signal including identification information.

[0119] The amount of electricity stored in the power storage unit 204 varies for each receiver 200. Therefore, by transmitting a response signal when the amount of electricity stored in the power storage unit 204 reaches a predetermined amount, the timing of transmitting data signals from the multiple receivers 200 can be staggered. Consequently, interference between data signals transmitted from the multiple receivers 200 to the transmitter 100 can be avoided, and situations in which the transmitter 100 is unable to receive data signals can be improved.

[0120] Note that in this embodiment, it is assumed that the transmitter 100 is arranged so as to be able to feed power approximately uniformly throughout the entire space. Therefore, the pairing in this embodiment is different from the pairing for efficiently transmitting the power supply signal from the transmitter 100 to the receiver 200.

[0121] Therefore, according to the system 1 of the present embodiment, in the wireless power supply system, pairing between the transmitter 100 and the plurality of receivers 200 can be efficiently performed.

[0122] Furthermore, in the above-described embodiment, transmitter 100 instructs multiple receivers 200 to switch to the first mode for associating transmitter 100 with receiver 200. After instructing the switch to the first mode, transmitter 100 transmits identification information of transmitter 100 to multiple receivers 200. Receiver 200 then transmits a data signal to the transmitter 100 identified by the received identification information. Therefore, in addition to initiating pairing, the pairing process can also be efficiently performed on already operating receivers 200. Operating receivers 200 are installed near the corresponding sensors. Since the pairing process can be performed collectively for all operating receivers 200, an administrator does not need to visit each location where a receiver 200 is installed, reducing the burden associated with pairing. Furthermore, since the switch to the first mode can be wirelessly instructed, there is no need to, for example, press a physical button on receiver 200 to switch to pairing mode, reducing the burden associated with pairing.

[0123] In addition, in the above embodiment, the transmitter 100 modulates the power signal with a signal for instructing the plurality of receivers 200 to switch to the first mode. Therefore, the pairing process can be performed more efficiently by instructing the receivers 200 to switch to the first mode by transmitting the power signal.

[0124] Furthermore, in the above-described embodiment, the transmitter 100 transmits the identification information of the transmitter 100 to the receiver 200 by transmitting a power supply signal modulated with the identification information of the transmitter 100. Therefore, by transmitting the power supply signal, the identification information of the transmitter 100 can be notified to the receiver 200, thereby enabling a more efficient pairing process.

[0125] In addition, in the above embodiment, the first mode for associating the transmitter 100 and the receiver 200 with each other is preset in the receiver 200. The transmitter 100 transmits the identification information of the transmitter to the receiver 200 in the first mode. The receiver 200 transmits a data signal to the transmitter 100 identified by the received identification information. Therefore, the pairing process can be efficiently performed on the receiver 200 set to the first mode as the initial state.

[0126] Furthermore, in the above-described embodiment, receiver 200 transmits data signals according to specifications based on the receiver identification information. Therefore, even when data signals are transmitted from multiple receivers 200 at approximately the same time, interference between the data signals can be suppressed. In other words, transmitter 100 can receive each data signal.

[0127] Furthermore, in the above embodiment, the receiver 200 transmits data signals using a frequency, a period, or a combination thereof corresponding to its identification information. Therefore, even when data signals are transmitted from a plurality of receivers 200 at approximately the same time, interference between the data signals can be suppressed.

[0128] <Modification>

[0129] In the above embodiment, the case where the transmitter 100 transmits the power supply signal modulated with a predetermined signal has been described. However, the power supply signal does not necessarily need to be modulated.

[0130] Figure 8 is a block diagram showing a configuration example of a transmitter 100 and a receiver 200 according to a modification. Figure 8 In, with Figure 2 The transmitter 100 and the receiver 200 shown are different in that the transmitter 100 is not equipped with a modulator 107 and the receiver 200 is not equipped with a demodulator 209.

[0131] Figure 9 1 is a diagram for explaining another example of the operation of the transmitter 100 and the plurality of receivers 200 when the transmitter 100 and the plurality of receivers 200 perform pairing. Figure 9 In the illustrated example, the receiver 200 is performing pairing with the transmitter 100 for the first time.

[0132] When multiple receivers 200 exist within a predetermined range, the administrator of the WPT system 1 instructs the transmitter 100 to start pairing. The instruction to start pairing can be input by pressing a physical button provided on the transmitter 100 or input through the first information processing device 300.

[0133] In step S31, when pairing starts, the microcontroller 103 of the transmitter 100 causes the transmitting antenna 102 to transmit a power supply signal that is not modulated with a command signal or identification information. For example, the transmitting antenna 102 transmits a signal oscillated by the oscillator 101 as the power supply signal.

[0134] Multiple receivers 200 located within a predetermined range of transmitter 100 receive the power signal radiated from transmitter 100. Receivers 200 are charged by the power signal transmitted by transmitter 100. Specifically, receiving antenna 201 receives the power signal. Rectifier 202 rectifies the received power signal and converts it into a DC voltage. Power management unit 203 controls the charging voltage based on the DC voltage and charges power storage unit 204.

[0135] and Figure 6 The example shown is the same, and the transmitter 100 and the receiver 200 perform steps S16 to S18. Figure 9 In step S17, since the receiver 200 does not recognize the identification information of the transmitter 100, the receiver 200 transmits the data signal without specifying the identification information of the transmitter 100. Therefore, the microcontroller 103 stores the identification information of the receiver 200 in the receiver information 1062.

[0136] In step S32, the microcontroller 103 transmits a data signal including identification information of the device itself (transmitter) to multiple receivers 200. Specifically, the microcontroller 103 reads the transmitter's identification information from the transmitter information 1061 and modulates a carrier wave with the read identification information, thereby generating a data signal. The microcontroller 103 reads the identification information of the relevant receiver 200 from the receiver information 1062 and sets it as the transmission destination. The microcontroller 103 radiates the data signal from the data transceiver antenna 105 to the receiver 200 serving as the destination.

[0137] In step S33, the microcontroller 205 registers the transmitter 100. Specifically, the receiving antenna 201 demodulates the received data and acquires the identification information of the transmitter 100. The microcontroller 203 stores the acquired identification information in the receiver information 2081.

[0138] In step S34, the microcontroller 103 terminates the pairing process. Specifically, the microcontroller 103 terminates the pairing process when all data signals transmitted to the receiver 200 are normally received by the receiver 200. If the receiver 200 does not normally receive the data signal, the microcontroller 103 repeatedly transmits the data signal to the receiver 200 that did not normally receive the data signal.

[0139] Thus, the transmitter 100 and the receiver 200 are associated with each other, and a data signal is transmitted and received between the associated transmitter 100 and receiver 200 .

[0140] In this way, even if the transmitter 100 is not equipped with the modulator 107 and the receiver 200 is not equipped with the demodulator 209, the transmitter 100 sends a data signal including the identification information of the transmitter to the receiver 200, thereby enabling effective pairing between the transmitter 100 and the receiver 200.

[0141] In addition, in the above embodiment Figure 6 and Figure 7 In the embodiment, as shown in step S17, the example in which the receiver 200 transmits the data signal by specifying the identification information of the transmitter 100 has been described. However, the operation of the receiver 200 at this time is not limited thereto. Figure 6 and Figure 7 In step S17, the receiver 200 may transmit the data signal without setting the identification information.

Therefore, the computer 90 is a concept that includes not only computers 90 housed in a single housing or chassis but also virtualized computer systems.

[0150] <Basic Functional Configuration of Computer 90>

[0151] Description by Figure 10 The basic hardware configuration of the computer 90 shown in FIG. 90 implements the functional configuration of the computer. The computer includes at least functional units of a control unit, a storage unit, and a communication unit.

[0152] Note that the functional units of the computer 90 can be implemented by distributing all or part of each functional unit across a plurality of computers 90 interconnected via a network. Therefore, the computer 90 is a concept that includes not only a single computer 90 but also a virtualized computer system.

[0155] A database is a relational database (RDB) that manages interrelated data sets in a tabular format defined by rows and columns, called tables. In a database, a table is called a table, a column in a table is called a column, and a row in a table is called a record. In a relational database (RDB), relationships between tables can be defined, and tables can be associated with each other.

[0156] Typically, each table has a set of columns that serve as a key to uniquely identify records. However, it is not necessary to set keys for columns.

Furthermore, the communication unit can transmit information output from the control unit to another computer 90.

[0160] Furthermore, at least one processor may be a processor in a broad sense, such as a hardware circuit (eg, a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC)) that performs part or all of the processing.

[0161] In the above description, the expression "xxx table" is used to describe information about the output of an input. This information can be data of any structure or a learning model, such as a neural network that generates outputs for an input.

[0163] In addition, in the above description, there are cases where "program" is used as a subject when describing processing. However, since the program is executed by the processor and performs predetermined processing using a storage unit and / or an interface unit as appropriate, the processor (or a controller including a processor, a microcontroller, or other device) can be used as the subject of the processing.
