[Figure 7] Figure 7 is a flowchart showing information processing in an information processing system. [Modes for carrying out the invention]

[0011] [Embodiments of the present invention] Hereinafter, an information processing system of an embodiment of the present invention will be described with reference to the drawings.

[0012] Figure 1 is a block diagram showing the configuration of the information processing system 100. As shown in Figure 1, the information processing system 100 is connected to the solar power generation device 102 and the wind power generation device 104 via a network N. The solar power generation device 102 and the wind power generation device 104 are groups of sensors installed at predetermined locations in the city block. The installation location is any location where measurement is possible.

[0013] The information processing system 100 is composed of a first acquisition unit 110, a second acquisition unit 112, a calculation unit 114, an estimation unit 116, a presentation unit 118, and a data storage unit 120. For the simulation of the first acquisition unit 110 and the second acquisition unit 112, any method capable of analyzing known solar radiation and wind speed may be used.

[0014] The information processing system 100 is configured as a device and is implemented by a computer including a CPU (Central Processing Unit), a ROM (Read Only Memory) storing programs for realizing each processing routine, a RAM (Random Access Memory) temporarily storing data, a memory as storage means, and a network interface. Note that a GPGPU or an accelerator may be used instead of the CPU according to the suitability of each processing, and an arithmetic unit according to the processing may be used as appropriate. In particular, in the processing related to learning and inference, it is preferable to use a GPGPU or an accelerator.

[0015] The data storage unit 120 stores map data and weather data. The map data is a map of the block to be analyzed and includes information on the terrain, the shape and height of buildings. The weather data is the past and latest weather information at the acquisition time, as well as the predicted weather information, for the area including the block acquired from a server (not shown) of an external service providing weather information. The weather information includes information on the weather and wind speed.

[0016] The first acquisition unit 110 uses the map data to acquire the spatial distribution of solar radiation amount over time for the block to be analyzed. FIG. 2 is an example of the spatial distribution of solar radiation amount in the block. The first acquisition unit 110 performs solar radiation amount analysis at the block scale by simulation using the map data, and calculates the spatial distribution of solar radiation amount. Thereby, the spatial distribution of solar radiation amount as shown in FIG. 2 is obtained over time.

[0017] The second acquisition unit 112 uses the map data and the weather data to acquire the spatial distribution of wind speed over time for the block. FIG. 3 is an example of the spatial distribution of wind speed in the block. The second acquisition unit 112 performs numerical fluid analysis at the block scale by simulation using the map data, and calculates the spatial distribution of the wind speed of the outdoor natural wind by performing analysis using the weather data in the numerical fluid analysis. Thereby, the spatial distribution of wind speed as shown in FIG. 3 is obtained over time. In the example of FIG. 3, the places where the wind speed corresponds to 2.4 m / s or more are shown hatched.

[0018] The calculation unit 114 acquires the power generation amount of sunlight and the power generation amount of wind power from each of the solar power generation device 102 and the wind power generation device 104. The calculation unit 114 uses the acquired power generation amounts of sunlight and wind power to calculate, for each time zone in the time history, a first power generation characteristic representing the power generation capacity of the solar power generation device 102 and a second power generation characteristic representing the power generation capacity of the wind power generation device 104. If the power generation amount is the power generation amount of wind speed, it is obtained by "power generation amount of wind speed = wind speed × power generation capacity". Similarly, the power generation amount of sunlight is obtained by "power generation amount of sunlight = solar irradiance × power generation capacity". Thereby, the power generation capacity of each can be obtained from the power generation amount and the wind speed. Thereby, the first power generation characteristic and the second power generation characteristic as the power generation potential in the actual light environment can be calculated from the power generation amount of each device. Here, for the calculation of each power generation characteristic, for example, the power generation amount of the solar power generation device 102 and the power generation amount of the wind power generation device 104 belonging to the section may be totaled for each section of the block and calculated in section units, or may be calculated for each device. Further, the power generation characteristic may be calculated by calculating the power generation characteristic of the time zone for each average wind speed. As an example, it is calculated for each time zone such as 1 m / s, 2 m / s, 3 m / s, etc. for each average wind speed.

[0019] FIG. 4 is an example of an actual wind power generation device that acquires the power generation amount. The device to be installed uses such a small wind power generation device 104 and solar power generation device 102. Also, each device is assumed to be installed in a block by being integrally provided in a sensor at the power generation supply destination, for example.

[0020] As shown in Figure 4, a self-contained sensor equipped with a power generation device enables a variety of measurements. Outdoors, the location of power outlets limits the placement of measurement devices in places where power supply is difficult. Self-contained devices powered by batteries require the hassle of battery replacement. Measurement devices that utilize harvesting (mainly solar power) exist, but because they use only one type of energy, they lack stability due to temporal and spatial changes in the energy source. Recently, expectations are rising for monitoring technology using numerous sensors due to the miniaturization, low power consumption of sensors, and the use of AI technology. On the other hand, when the purpose is to monitor at the city block level, such as measuring the vibrancy of a city or using it for evacuation during disasters, simply installing sensors in a few locations is insufficient. It is necessary to construct a wide-area, high-density sensing network, and maintenance-free operation and temporal / spatial stability of the energy source are important issues.

[0021] The estimation unit 116 estimates the amount of solar power generated based on the spatial distribution of solar radiation and the first power generation characteristic, and estimates the amount of wind power generated based on the spatial distribution of wind speed and the second power generation characteristic. Then, the estimation unit 116 estimates the total amount of power generated by solar and wind power and outputs the estimation result.

[0022] Figure 5 shows an example of estimated power generation. (E1) is the distribution of estimated solar power generation, and (E2) is the distribution of estimated wind power generation. (E3) is the distribution of the total power generation, including both estimated solar and wind power generation.

[0023] The display unit 118 displays the block layout in the map data, and overlays the estimated power generation amount, which can be switched for each time period in the time history, with candidate installation locations for the solar power generation device 102 and the wind power generation device 104, based on the estimation results. Here, the display unit 118 may present at least one of the candidate locations and percentages for the installation of the solar power generation device 102 and the wind power generation device 104, respectively, as candidate installation locations. The display unit 118 may also accept at least one specification from the user regarding the period, time, and location range, and present candidate installation locations corresponding to the specification.

[0024] Figure 6 shows an example of a city block image with candidate options superimposed. As shown in Figure 6, candidate solar power generation equipment and candidate wind power generation equipment are displayed separately.

[0025] Next, the operation of the embodiments of the present invention will be described. Figure 7 is a flowchart of information processing in the information processing system 100. The arithmetic units of the CPU, GPGGPU, or accelerator of the information processing system 100 read programs and various data from ROM and execute them, thereby allowing the arithmetic units to perform processing as each part of the information processing system 100.

[0026] In step S100, the first acquisition unit 110 uses map data to acquire the spatial distribution of solar radiation over time for the block to be analyzed.

[0027] In step S102, the second acquisition unit 112 uses map data and weather data to acquire the spatial distribution of wind speed over time for each block.

[0028] In step S104, the calculation unit 114 obtains the amount of solar power generated and the amount of wind power generated from the solar power generation device 102 and the wind power generation device 104, respectively.

[0029] In step S106, the calculation unit 114 uses the acquired solar and wind power generation amounts to calculate a first power generation characteristic representing the power generation capacity of the solar power generation device 102 and a second power generation characteristic representing the power generation capacity of the wind power generation device 104 for each time period in the time history.

[0030] In step S108, the estimation unit 116 estimates the amount of solar power generated based on the spatial distribution of solar radiation and the first power generation characteristics, and estimates the amount of wind power generated based on the spatial distribution of wind speed and the second power generation characteristics.

[0031] In step S110, the display unit 118 displays the block in the map data, and overlays the estimated power generation amount, which can be switched for each time period in the time history, and candidate installation locations for the solar power generation device 102 and the wind power generation device 104, based on the estimation results.

[0032] As described above, according to the information processing system 100 of the embodiment of the present invention, candidate locations for optimal power generation equipment installation in a city block are visualized.

[0033] By referring to the installation locations of power generation devices in urban areas, as output by the information processing system 100 of this embodiment, it becomes possible to quantitatively visualize the power generation characteristics of ambient energy potential in low-power applications such as sensing networks, and utilize it as a stable power supply source. Furthermore, the amount and ratio of the ambient energy potential's power generation characteristics (sunlight:wind ratio) change over time. Moreover, the amount of energy (sunlight intensity, wind speed) and the amount of power generated are not directly proportional, and the range in which effective power generation can be obtained differs depending on the device. Therefore, visualization makes it possible to know in advance how much power can be supplied at which locations, enabling the development of sensing plans that make the most of the potential.

[0034] It should be noted that the present invention is not limited to the embodiments described above, and various modifications and applications are possible without departing from the spirit of the invention. [Explanation of Symbols]
