Description

Power generation system

[0001] The present disclosure relates to a power generation system.

[0002] A power generation system has been proposed that manages the amount of power generated by a power generation device such as a power generation floor for each user and returns a price (also referred to as an incentive) corresponding to the amount of power generated to the user (see, for example, Patent Document 1).

[0003] Japanese Patent Application Laid-Open No. 2016-224803

[0004] However, in the conventional technology, since power generation parameters such as the amount of power generated are obtained via a power storage device, after the power storage process is performed, a process for reducing the price is performed. Therefore, there is a problem that the process for power storage and the process for reducing the price cannot be performed in parallel, and the processing in the entire system is not efficient.

[0005] An object of the present disclosure is to solve the above problems and provide an efficient power generation system.

[0006] A power generation system according to an aspect of the present disclosure includes: a power generation device that generates power and outputs electricity; an arithmetic unit that calculates a power generation parameter based on an output from the power generation device; a result output unit that generates and outputs incentive data corresponding to the power generation parameter; and a power generation waveform processing unit that shapes and outputs the waveform of the electricity output from the power generation device, and is characterized in that the process of generating the incentive data and the process of outputting the waveform are performed in parallel.

[0007] According to the present disclosure, an efficient power generation system can be provided.

[0008] This is a block diagram schematically showing the configuration of the power generation system according to this embodiment. This is a diagram showing an example of the hardware configuration of a control unit applicable to the power generation system. This is a diagram showing another example of the hardware configuration of a control unit applicable to the power generation system. This is a diagram showing an example of a power generation device installed near a ticket gate at a train station. This is a diagram showing an example in which incentives based on incentive data are given to users by using the ticket gate. This is a diagram showing an example of a power generation device installed in a commercial facility. This is a diagram showing an example of a power generation device installed at an event venue. This is a diagram showing an example of a power generation floor as a power generation device. This is a diagram showing an example of a hand-cranked generator as a power generation device. This is a diagram showing an example of the internal structure of the hand-cranked generator shown in Figure 9.

[0009] Figure 1 is a schematic block diagram showing the configuration of the power generation system 1 according to this embodiment. The power generation system 1 includes a power generation device 11, a calculation unit 12, a result output unit 13, and a power generation waveform processing unit 14. As shown in Figure 1, the power generation system 1 may further include a power generation waveform output unit 15, an internal battery 16, and a trigger unit 17.

[0010] The power generation device 11 generates electricity and outputs electricity. Note that "electricity" is used as a general term for voltage, current, and power. The power generation device 11 generates electricity, for example, through mechanical action from the user 10. The power generation device 11 is, for example, a power-generating floor. In this case, electricity is generated when the user 10 steps on the power generation device 11. Information corresponding to the amount of electricity generated or the number of times electricity is generated in the power generation device 11 is output to the calculation unit 12 and the power generation waveform processing unit 14.

[0011] In this embodiment, the power generation device 11 generates electricity by electromagnetic induction. In this case, the power generation device 11 has a magnet and a power generation element (electromagnetic induction coil). In such a power generation device 11, an external force applied to the power generation device 11 by the user 10 causes a mechanical action acting on the power generation device 11, which causes a relative displacement of the positions of the magnet and the power generation element, thereby generating electromagnetic induction in the power generation element and generating electricity.

[0012] The calculation unit 12 calculates power generation parameters based on the output from the power generation device 11. For example, the calculation unit 12 calculates power generation parameters based on the output from the power generation device 11 and outputs the calculated power generation parameters to the result output unit 13. Power generation parameters are, for example, the number of times power is generated or the amount of power generated in the power generation device 11. The output from the power generation device 11 that the calculation unit 12 uses to calculate the power generation parameters is power generation information from the power generation device 11, such as the generated current value, voltage value, and the count value of a counter attached to the power generation device 11.

[0013] The power generation parameter may also be load information, which is information indicating the load pre-set on the power generation device 11. The load pre-set on the power generation device 11 is a parameter that represents the magnitude of the force required to relatively displace the positions of the magnet and the power generation element. The load information can be any information that indicates the magnitude of the load. The load information affects the amount of power generated and the number of power generation cycles of the power generation device. The larger the load, the greater the force required to relatively displace the positions of the magnet and the power generation element, making it more difficult to increase the number of power generation cycles, but increasing the amount of power generated per cycle. The smaller the load, the less force is required to relatively displace the positions of the magnet and the power generation element, making it easier to increase the number of power generation cycles, but decreasing the amount of power generated per cycle. The power generation parameter may also be velocity information, which indicates the displacement speed in the relative displacement between the magnet and the power generation element of the power generation device 11. The displacement speed is a parameter that represents the estimated speed between the magnet and the power generation element when relatively displacing the positions of the magnet and the power generation element. The velocity information can be any information that indicates the magnitude of the speed. The velocity information affects the amount of power generated by the power generation device. The faster the speed, the greater the amount of power generated.

[0014] Figure 2 shows an example of the hardware configuration of a control unit 20 applicable to the power generation system 1. Figure 3 shows another example of the hardware configuration of a control unit 20 applicable to the power generation system 1. One of the calculation unit 12, the result output unit 13, the power generation waveform processing unit 14, and the power generation waveform output unit 15, or two or more combinations selected from these, can be configured in the control unit 20, for example.

[0015] The control unit 20 is composed of, for example, at least one processor 21 and at least one memory 22. The processor 21 is, for example, a CPU (Central Processing Unit) that executes a program stored in the memory 22. The processor 21 may be a processing unit, arithmetic unit, microprocessor, microcomputer, or DSP (Digital Signal Processor). In this case, the functions of one or more of the arithmetic unit 12, result output unit 13, power generation waveform processing unit 14, and power generation waveform output unit 15 are realized by software, firmware, or a combination of software and firmware. The software and firmware can be stored as a program in the memory 22. With this configuration, the program for realizing the functions of the control unit 20 is executed by the computer.

[0016] The memory 22 is a recording medium readable by a computer, and is, for example, volatile memory such as RAM (Random Access Memory) and ROM (Read Only Memory), non-volatile memory, or a combination of volatile and non-volatile memory.

[0017] The control unit 20 may have a plurality of processors 21 and a plurality of memories 22. In this case, the functions of one of the calculation unit 12, the result output unit 13, the power generation waveform processing unit 14, and the power generation waveform output unit 15, or two or more combinations selected from these, are realized by these plurality of processors 21 and plurality of memories 22.

[0018] The control unit 20 may be composed of a processing circuit 23 as dedicated hardware, such as a single circuit or a composite circuit. The processing circuit 23 may be, for example, a system LSI, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination of any of these. In this case, the functions of one of the arithmetic unit 12, the result output unit 13, the power generation waveform processing unit 14, and the power generation waveform output unit 15, or two or more combinations selected from these, are realized by the processing circuit 23.

[0019] The result output unit 13 generates and outputs incentive data according to the power generation parameters. The incentive data is generated according to the power generation parameters, and for example, the larger the amount of power generated, the higher the reward may be for the incentive data. Also, for example, the larger the number of power generation cycles, the higher the reward may be for the incentive data. In addition, for example, the larger the load indicated by the load information or the larger the speed indicated by the speed information, the higher the reward may be for the incentive data. Furthermore, the incentive data may be generated according to power generation parameters that combine multiple of the amount of power generated, the number of power generation cycles, the load information, and the speed information, and for example, the incentive data may be highly rewarding in response to a small number of power generation cycles but a large load indicated by the load information. Also, the incentive data may be even more rewarding in response to a large amount of power generated, a large number of power generation cycles, a large load indicated by the load information, and a large speed indicated by the speed information. Conversely, the incentive data may be more rewarding in response to a small amount of power generated, a small number of power generation cycles, a small load indicated by the load information, and a small speed indicated by the speed information, or in response to a combination of these. The result output unit 13 provides the user 10 with an incentive based on the incentive data.

[0020] The power generation waveform processing unit 14 shapes and outputs the waveform of the electricity output from the power generation device 11. For example, if the power generation system 1 has an internal battery 16, the power generation waveform processing unit 14 rectifies the voltage or current generated by the power generation device 11 and outputs the electricity represented by the rectified voltage or current to the internal battery 16. When the amount of charge stored in the internal battery 16 exceeds a predetermined threshold, the power generation waveform processing unit 14 outputs the electricity represented by the rectified voltage or current to the power generation waveform output unit 15. The power generation waveform processing unit 14 may output the shaped waveform to the power generation waveform output unit 15 regardless of whether or not there is an internal battery 16. Alternatively, the power generation waveform processing unit 14 may shape the waveform of the current or voltage without rectifying the voltage or current output from the power generation device 11.

[0021] When an external battery 2 is connected to the power generation system 1, the power generation waveform processing unit 14 may convert the current generated by the power generation device 11 into alternating current (AC) and output that AC to the power generation waveform output unit 15. The external battery 2 is an example of an external device. External devices may be, for example, drive devices such as motors, display devices such as displays, etc. The power generation waveform processing unit 14 may output the current generated by the power generation device 11 as DC without converting it into AC, or it may output it as AC beforehand. In other words, the power generation device 11 can output electricity as DC or AC depending on the connected external device.

[0022] As described above, information corresponding to the electricity generated by the power generation device 11 is output to the calculation unit 12 and the power generation waveform processing unit 14. The calculation unit 12 generates incentive data, and the power generation waveform processing unit 14 shapes the waveform for outputting the electricity from the power generation device 11 to the internal battery 16 or the power generation waveform output unit 15. These processes are carried out in parallel, thereby providing an efficient power generation system 1.

[0023] The power generation waveform output unit 15 outputs electricity represented by a waveform formed by the power generation waveform processing unit 14 toward the external battery 2. The power generation waveform output unit 15 outputs power (alternating current or voltage) generated by the power generation device 11 and processed by the power generation waveform processing unit 14, or power (direct current or voltage) from the internal battery 16, to an external device, functioning as an auxiliary power source to operate the external device, or, if the external device is the external battery 2, as an auxiliary charger for the external battery 2.

[0024] The electricity represented by the waveform formed by the power generation waveform processing unit 14 may be stored in the internal battery 16 if the system includes an internal battery 16.

[0025] As described above, the power generation system 1 can perform incentive processing, which is the process of generating incentive data, and waveform processing, which is the process of shaping and outputting a waveform for outputting the electricity output from the power generation device 11 toward the internal battery 16 or external equipment, in parallel.

[0026] Furthermore, the power generation system 1 can perform the process of providing an incentive to the user 10 and the process of outputting the electricity generated from the power generation device 11 to the internal battery 16 or the external battery 2 (external device) in parallel.

[0027] As described above, the power generation system 1 can perform the process of providing an incentive to the user 10 and the process of storing the electricity generated by the power generation device 11 in the internal battery 16 or outputting it to an external device in parallel, thereby providing an efficient power generation system 1. Furthermore, since an incentive is given to the user 10 and electricity is generated each time the user 10 uses the power generation system 1, the user 10 is given an incentive to use the power generation system 1, and the power generation system 1 can be provided that contributes to carbon neutrality.

[0028] The trigger unit 17 outputs identification information to identify the user 10 who will receive an incentive based on incentive data. The trigger unit 17 outputs the identification information to the calculation unit 12. When the calculation unit 12 receives the output from the trigger unit 17, it starts calculating the power generation parameters. The trigger unit 17 may be an electronic device such as an IC card reader, or a device operated by the user 10, such as a button or switch. The trigger unit 17 may also be a camera, for example. The identification information is output when the trigger unit 17 receives input from an external source. For example, if the trigger unit 17 is an IC card reader, the trigger unit 17 receives input from an external source when the user holds an IC card over the IC card reader and outputs the identification information.

[0029] The identification information includes at least one of start information and end information. The start information is information for initiating the calculation of power generation parameters in the calculation unit 12. The end information is information for determining the end of the calculation of power generation parameters in the calculation unit 12 after the start information has been input to the calculation unit 12. For example, the calculation unit 12 determines the number of power generation cycles, the amount of power generated, or the estimated speed of the magnets of the power generation device 11 as power generation parameters from the time the start information is input to the calculation unit 12 until the end information is input to the calculation unit 12.

[0030] The identification information, start information, and end information may include incentive information indicating the type of incentive given to the user. The types of incentives can be diverse, but examples include points redeemable for various services, discounts on various usage fees, etc. When the result output unit 13 generates incentive data corresponding to the power generation parameters calculated by the calculation unit 12, it can generate incentive data in which the type of incentive has been determined based on the incentive information.

[0031] An example of how power generation system 1 is applied is described below.

[0032] Figure 4 shows an example of a power generation device 11 installed near the ticket gates at a train station. In the example shown in Figure 4, a power generation floor, which serves as the power generation device 11, is installed near the entrance to the ticket gates. In this case, when a user 10 steps on the power generation device 11, the power generation device 11 generates electricity. The electricity generated by the power generation device 11 is output to the power generation waveform processing unit 14. Power generation information based on the electricity output from the power generation device 11 due to the user 10's actions is output to the calculation unit 12.

[0033] Figure 5 shows an example in which an incentive based on incentive data is given to user 10 by using a ticket gate. In the example shown in Figure 5, a power generation floor as a power generation device 11 is provided near the entrance of the ticket gate, and an IC reader as a trigger unit 17 is provided on the ticket gate. When user 10 enters the ticket gate, user 10 generates electricity using the power generation device 11. When user 10 holds an IC (Integrated Circuit) card over the trigger unit 17 provided on the ticket gate, the trigger unit 17 reads user 10's IC card and outputs user 10's identification information. When the trigger unit 17 receives input from an external source, the trigger unit 17 includes start information in the identification information that identifies user 10 and outputs it to the calculation unit 12.

[0034] The calculation unit 12 determines the number of power generation cycles or the amount of power generated, or the estimated speed of the magnet of the power generation device 11, as power generation parameters from the time the start information is input to the calculation unit 12 until the end information is input to the calculation unit 12. For example, when the calculation unit 12 acquires the start information, it calculates the number of power generation cycles as 1 and adds this number to the user's 10 existing number of power generation cycles to calculate the power generation parameters.

[0035] If the trigger unit 17 receives external input again after outputting start information to the calculation unit 12, the trigger unit 17 outputs end information along with the identification information to the calculation unit 12. For example, when a user 10 exits a ticket gate, and the user 10 holds their IC card over the trigger unit 17 provided on the ticket gate, the trigger unit 17 reads the user 10's IC card and outputs identification information to identify the user 10. The trigger unit 17 outputs end information to the calculation unit 12. When the calculation unit 12 obtains the end information, it outputs the power generation parameters to the result output unit 13.

[0036] If a predetermined time has elapsed since the trigger unit 17 outputted start information to the calculation unit 12, the trigger unit 17 may output end information along with the identification information to the calculation unit 12. For example, the trigger unit 17 may output start information to the calculation unit 12, and then output end information to the calculation unit 12 after a predetermined time has elapsed.

[0037] The result output unit 13 provides the user 10 with incentive data (e.g., points) corresponding to power generation parameters (e.g., cumulative number of cycles). Points are, for example, data equivalent to money. As a result, for example, the points as an incentive are recorded on the user 10's IC card. The incentive data may also be recorded on a server that is communicatively connected to the power generation system 1.

[0038] Incentive information may be included in any of the identification information, start information, or end information. Incentive information may be input to the calculation unit 12 or the result output unit 13 from outside the power generation system 1. Incentive information is, for example, information about user 10. Information about user 10 is, for example, information such as IC card identification information and the number of times power has been generated. The power generation system 1 may obtain information about user 10 from an IC reader or an external device (for example, a server).

[0039] When user 10 exits the ticket gate, the trigger unit 17 does not need to output end information. In this case, when user 10 enters the ticket gate, the trigger unit 17 outputs start information to the calculation unit 12, and upon receiving the start information, the calculation unit 12 calculates the power generation parameters and outputs those power generation parameters to the result output unit 13. When user 10 enters the ticket gate, the trigger unit 17 may output both start information and end information to the calculation unit 12 simultaneously.

[0040] Figure 6 shows an example of a power generation device 11 installed in a commercial facility. In the example shown in Figure 6, the power generation device 11 is installed near the entrance or exit of an escalator. For example, when a user 10 steps on the power generation device 11, the power generation device 11 generates electricity. The electricity generated by the power generation device 11 is output to the power generation waveform processing unit 14. Power generation information based on the electricity output from the power generation device 11 due to the user 10's actions is output to the calculation unit 12.

[0041] A trigger unit 17 may be provided in the power generation device 11 shown in Figure 6. For example, when a user 10 gets on the escalator, the trigger unit 17 outputs identification information of the user 10. When the trigger unit 17 receives input from an external source, the trigger unit 17 outputs identification information that identifies the user 10 to the calculation unit 12. Also, as shown in Figure 6, the power generation device 11 may be provided in a location other than the entrance or exit of the escalator. For example, the power generation device 11 may be provided in a rest area or amusement park area in a commercial facility. In such cases, trigger units 17 may be provided at the entrances and exits of each space.

[0042] Figure 7 shows an example of a power generation device 11 installed at an event venue. In the example shown in Figure 7, the power generation system 1 is used together with a display device 3 installed at the event venue. The power generation system 1 is applicable to digital signage having a display device 3.

[0043] In the example shown in FIG. 7, the power generation system 1 has a plurality of power generation devices 11. For example, one power generation device 11 is assigned to each of the plurality of users 10, and each user 10 competes in the amount of power generation or the number of power generation times within a predetermined time using the power generation device 11.

[0044] Power generation may be performed by a team composed of a plurality of users 10 using one power generation device 11. In this case, a plurality of teams compete in the amount of power generation or the number of power generation times within a predetermined time.

[0045] The calculation unit 12 calculates power generation parameters for each power generation device 11 and outputs them to the result output unit 13. The result output unit 13 outputs, for example, incentive data corresponding to each power generation device 11 to the display device 3, so that information based on the incentive data corresponding to each user 10 is displayed on the display device 3. Information based on the incentive data is, for example, information indicating the amount of power generation or the number of power generation times of each user 10. The result output unit 13 gives, for example, an incentive based on the incentive data to each user 10.

[0046] FIG. 8 is a diagram showing an example of a power generation floor 110 as the power generation device 11. The power generation floor 110 has a tread plate 111, a magnet 112, and a power generation element 113 for generating power by electromagnetic induction caused by the relative displacement of the magnet 112. The power generation element 113 has, for example, a coil 116, a magnetic flux concentrator 117, and a magnetic core 118. The power generation floor 110 generates power when stepped on by the user 10. The power generation floor 110 may further have an elastic member 114 such as a spring for adjusting the load applied to the tread plate 111 and a support member 115 for supporting the tread plate 111. Such a power generation device 11 can generate power by the relative displacement of the positions of the magnet 112 and the power generation element 113, and can generate power stably. The power generation amount of the power generation device 11 changes according to the moving speed of the magnet 112 with respect to the power generation element 113 or the displacement amount of the magnet 112 in the relative displacement between the magnet 112 and the power generation element 113. By basing on the speed or amount of stepping on the tread plate 111 for generating power on the power generation floor 110, an incentive corresponding to the power generation parameter, the amount of power generation, and the speed information can be given to the user 10.

[0047] When generating electricity using the power generation floor 110, the load (i.e., the external force applied to the power generation device 11 by the user to generate electricity) can be arbitrarily set. For example, by setting the distance between the magnet 112 and the power generation element 113, the magnetic attraction force changes, and the load for stepping on the treadle 111 is adjusted. By adjusting the load for stepping on the treadle 111 to generate electricity with the power generation floor 110, an incentive according to the load information as a power generation parameter can be given to the user 10.

[0048] FIG. 9 is a diagram showing an example of a hand-cranked generator 120 as the power generation device 11. FIG. 10 is a diagram showing an example of the internal structure of the hand-cranked generator 120 shown in FIG. 9. The power generation device 11 is not limited to the power generation floor 110. For example, the power generation device 11 may be the hand-cranked generator 120 shown in FIGS. As the hand-cranked generator 120 is operated by the user 10, electricity is generated. The hand-cranked generator 120 can be provided at any location in indoor facilities or outdoor facilities.

[0049] The hand-cranked generator 120 includes a magnet 121, a power generation element 122 for generating electricity by electromagnetic induction with the magnet 121, and an operation unit 123 for rotating the magnet 121 or the power generation element 122. The power generation element 122 has, for example, a coil, a magnetic flux concentrator, and a magnetic core. For example, the user 10 generates electricity by rotating the magnet 121 using the operation unit 123. Such a power generation device 11 can generate electricity by the relative displacement of the positions of the magnet 121 and the power generation element 122, and can generate electricity stably. The amount of electricity generated by the power generation device 11 changes according to the moving speed of the magnet 121 with respect to the power generation element 122 or the displacement amount of the magnet 121 in the relative displacement between the magnet 121 and the power generation element 122. The calculation unit 12 may estimate the moving speed of the magnet 121 or the displacement amount of the magnet 121. The result output unit 13 can acquire the value estimated by the calculation unit 12 as a power generation parameter and give an incentive according to the power generation parameter to the user 10.

[0050] The load when generating electricity using the hand-cranked generator 120 (i.e., the external force applied by the user to the power generation device 11 to generate electricity) can be arbitrarily set. For example, by setting the distance between the magnet 121 and the power generation element 122, the magnetic attraction force changes, and the load required to operate the control unit 123 is adjusted. By adjusting the load required to operate the control unit 123 to generate electricity with the hand-cranked generator 120, an incentive can be given to the user 10 according to the load information as a power generation parameter.
