[0014] An example of an embodiment of the present disclosure will be described below with reference to the drawings. The same reference numerals are used throughout the drawings to designate identical or equivalent components and parts. The dimensional proportions of the drawings are exaggerated for illustrative purposes and may differ from the actual proportions.

[0015] 1 is a diagram showing an example of the appearance of an illuminance meter according to this embodiment. The illuminance meter 1 according to this embodiment has a function of displaying information about plants suitable for cultivation in a location, whether indoors or outdoors, when a user measures illuminance and inputs information about temperature. The information about temperature may be input as information about a desired flowering time or as information about the actual temperature.

[0016] Illuminance meter 1 comprises an input unit 15, a display unit 16, and an illuminance sensor 18. Input unit 15 is made up of one or more buttons that allow the user to perform various operations on illuminance meter 1. Display unit 16 displays information about illuminance measured by illuminance sensor 18. Furthermore, when the user measures illuminance and inputs information about temperature, display unit 16 displays information about plants that are suitable for cultivation in the location where the illuminance was measured, whether indoors or outdoors. Details of the process of displaying information on display unit 16 will be described later. Illuminance sensor 18 is provided so as to face the outside of the housing of illuminance meter 1.

[0017] FIG. 2 is a block diagram showing the hardware configuration of the illuminance meter 1. As shown in FIG.

[0018] 2, the illuminance meter 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a storage 14, an input unit 15, a display unit 16, a communication interface (I / F) 17, and an illuminance sensor 18. Each component is connected to each other via a bus 19 so as to be able to communicate with each other.

[0019] CPU 11 is a central processing unit that executes various programs and controls each component. That is, CPU 11 reads programs from ROM 12 or storage 14 and executes the programs using RAM 13 as a work area. CPU 11 controls the above components and performs various arithmetic processing in accordance with the programs recorded in ROM 12 or storage 14. In this embodiment, ROM 12 or storage 14 stores an information presentation program that displays information about plants suitable for cultivation in a location where illuminance has been measured.

[0020] The ROM 12 stores various programs and various data. The RAM 13 temporarily stores programs or data as a working area. The storage 14 is configured with a storage device such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or flash memory, and stores various programs including the operating system and various data.

[0021] The input unit 15 is used by the user to input various types of information to the illuminance meter 1.

[0022] The display unit 16 is, for example, a liquid crystal display, and displays various information. The display unit 16 may also function as the input unit 15 by adopting a touch panel system.

[0023] The communication interface 17 is an interface for communicating with other devices, and uses standards such as Ethernet (registered trademark), FDDI, and Wi-Fi (registered trademark).

[0024] The illuminance sensor 18 is composed of, for example, an optical filter that matches the sensitivity of the human eye, a photoelectric conversion element such as a photodiode, and the like, and outputs a current corresponding to the brightness of the received light.

[0025] When executing the information presentation program, the illuminance meter 1 uses the hardware resources described above to realize various functions. The functional configuration realized by the illuminance meter 1 will be described below.

[0026] FIG. 3 is a block diagram showing an example of the functional configuration of the illuminance meter 1.

[0027] 3, the illuminance meter 1 has, as its functional components, an illuminance measurement unit 101, a temperature information acquisition unit 102, and an information presentation unit 103. Each functional component is realized by the CPU 11 reading and executing an information presentation program stored in the ROM 12 or the storage 14.

[0028] The illuminance measurement unit 101 measures the illuminance at the location where the illuminance meter 1 is located based on the current output by the illuminance sensor 18. In particular, in the illuminance meter 1 according to this embodiment, the illuminance measurement unit 101 measures the illuminance at the planting location where the user wishes to plant a tree.

[0029] The temperature information acquisition unit 102 acquires temperature-related temperature information. The temperature information input by the user includes information on the current season input by the user, information on the season in which the user desires plants to bloom, and temperature information on the location where the illuminance is measured by the illuminometer 1. The temperature information on the location where the illuminance is measured by the illuminometer 1 may be input by measuring it using a separate thermometer, or the illuminometer 1 may be equipped with a temperature sensor that measures temperature, and the temperature measured by that temperature sensor may be used.

[0030] The information presentation unit 103 presents information based on the illuminance measured by the illuminance measurement unit 101 on the display unit 16. The information presentation unit 103 presents the value of illuminance on the display unit 16 as information based on the illuminance measured by the illuminance measurement unit 101. Furthermore, the information presentation unit 103 presents information about plants suitable for cultivation in the target planting location where the illuminance was measured as information based on the illuminance measured by the illuminance measurement unit 101.

[0031] When presenting information about plants suitable for cultivation in the target planting location where the illuminance has been measured, the information presentation unit 103 refers to the plant information database 110. The plant information database 110 is a database that stores, for each type or variety of plant, information about the flowering period, flowering season, information about the light (illuminance) for cultivating the plant, information about the temperature for cultivating the plant, other information about plant cultivation, information about areas where the plant can be cultivated, and information about available distribution status.

[0032] 4 is a diagram illustrating a specific example of the plant information database 110. The plant information database 110 includes a plant column 111 for identifying the plant, a column 112 for the minimum illuminance for cultivating the plant, a column 113 for the maximum illuminance for cultivating the plant, a column 114 for the temperature required for the plant to grow, a column 115 for the irradiation time required for the plant to grow, a column 116 for the flowering period when the plant blooms, a column 116 for the cultivated regions where the plant can be cultivated, and a column 118 for distribution information and available distribution trends for seeds or seedlings of the plant.

[0033] For example, if the illuminance measured by the illuminance measurement unit 101 is 2000 lux, the information presentation unit 103 refers to the plant information database 110 and extracts plants whose minimum and maximum illuminances are within a range of 2000 lux. In the example of Fig. 4, this applies to plants C and E. Therefore, in this case, the information presentation unit 103 presents plants C and E on the display unit 16 as plants suitable for cultivation in the target planting location.

[0034] The information presentation unit 103 may present information about plants suitable for cultivation in the planting location where the illuminance was measured, based on the illuminance measured by the illuminance measurement unit 101 as well as the temperature information acquired by the temperature information acquisition unit 102. For example, when a desired flowering period is input as temperature information, the information presentation unit 103 refers to the plant information database 110 and extracts plants that match the illuminance and desired flowering period or desired flowering season from the plant information database 110. The desired flowering period may be input on a monthly, seasonal, or temperature (temperature) basis. When the desired flowering period is input on a monthly or seasonal basis, the illuminance meter 1 may store temperature information corresponding to each month or season in advance in the form of a table. As an example, the temperature values ​​for each season when the desired flowering period is input on a seasonal basis are shown below. Spring: 9℃~20℃ Summer: 20℃~28℃ Autumn: 9℃~20℃ Winter: 2℃~9℃

[0035] For example, if the illuminance measured by the illuminance measurement unit 101 is 2000 lux and the desired flowering season is autumn, then in the example of Fig. 4, plant E would be the appropriate plant. Therefore, in this case, the information presentation unit 103 presents plant E on the display unit 16 as a plant suitable for cultivation in the target planting location.

[0036] The illuminometer 1 may be configured to accept input of temperature information after the information presentation unit 103 presents information about plants based on illuminance. This allows the illuminometer 1 to first provide the user with options for cultivable plants based on illuminance, and then present information about cultivable plants based on temperature information.

[0037] The illuminance meter 1 may also use the location information of the planting location to refer to the plant information database 110 and present information about plants that can be cultivated. The location information may be input by the user, or, as shown in FIG. 5, the illuminance meter 1 may be provided with a location information acquisition unit 104 consisting of a location information sensor and the information output by the location information sensor may be used.

[0038] When the information presentation unit 103 refers to the plant information database 110 and finds that there is a plant that is not suitable for cultivation due to insufficient illuminance, the information presentation unit 103 may present on the display unit 16 information on the illuminance to be added to the planting location in order to cultivate the plant, or information on lighting to add illuminance.

[0039] For example, if the illuminance measured by the illuminance measurement unit 101 is 700 lux and it is desired to cultivate plant D at that location, referring to the plant information database 110 reveals that there is insufficient brightness to cultivate plant D. Therefore, the information presentation unit 103 may present on the display unit 16 that plant D can be cultivated at that location by adding brightness in the range of 100 to 500 lux.

[0040] The information presentation unit 103 may extract multiple plants from the plant information database 110 based on the illuminance and temperature information. If the user desires to cultivate multiple plants in the planting location, the information presentation unit 103 may present on the display unit 16 information to supplement with other lighting devices an illuminance that is a predetermined percentage (e.g., 70%) of the median of the illuminance range of the plant that requires the highest illuminance among the multiple plants extracted from the plant information database 110.

[0041] With such a configuration, the illuminance meter 1 according to an embodiment of the present disclosure can present information about plants appropriate for the location where the plant is desired to be grown by using information about the illuminance of the location where the plant is desired to be grown.

[0042] Next, the operation of the illuminance meter 1 will be described.

[0043] 6 is a flowchart showing the flow of the information presentation process by the illuminance meter 1. The CPU 11 reads out an information presentation program from the ROM 12 or the storage 14, loads it into the RAM 13, and executes it, thereby performing the information presentation process.

[0044] In step S101, the CPU 11 measures the illuminance at the location where the illuminance is to be measured, that is, the target planting location, based on the current value output from the illuminance sensor 18.

[0045] Following step S101, in step S102, CPU 11 acquires temperature information related to temperature. The temperature information may include information about the current season input by the user, information about the season in which the plant is desired to bloom, and information about the temperature of the location where the illuminance is measured by illuminometer 1. Note that the temperature information about the location where the illuminance is measured by illuminometer 1 may be input by the user measuring it using a separate thermometer, or the illuminometer 1 may be equipped with a temperature sensor that measures temperature, and the temperature measured by that temperature sensor may be used.

[0046] Following step S102, in step S103, the CPU 11 refers to the plant information database 110 based on the measured illuminance and the acquired temperature information, and displays on the display unit 16 information about plants that are suitable for cultivation in the planting location where the illuminance was measured.

[0047] 7 is a diagram showing an example of information on illuminance at the target planting location where the illuminance was measured, information on the flowering period, and information on plants suitable for cultivation in the target planting location, presented by the CPU 11 on the display unit 16. In FIG. 7, the illuminance at the target planting location measured by the illuminance sensor 18 is 1600 lux, and the user has input that the desired flowering period is summer. As a result of referring to the plant information database 110, the display unit 16 presents plant C as a plant suitable for cultivation in the target planting location where the illuminance was measured. Note that although only one plant is presented on the display unit 16 in FIG. 7, the CPU 11 may present multiple plants as plants suitable for cultivation in the target planting location.

[0048] As shown in Figure 7, the CPU 11 can provide the user of the illuminance meter 1 with information on what plants should be grown in the planting location by presenting plants that are suitable for cultivation in the planting location where the illuminance was measured.

[0049] The CPU 11 may designate a plant desired to be cultivated by a user, measure the illuminance at the target planting location, and refer to the plant information database 110. If the illuminance is too low or too high for the designated plant, the CPU 11 may display information on the display unit 16 about the illuminance to be added to the target planting location for cultivating the plant, or information about lighting for adding illuminance. The CPU 11 may also display information about the illuminance or deficiency of the plant extracted from the plant information database 110 in a format that is adapted to growth and selection conditions other than illuminance. FIGS. 8A to 8C are diagrams showing examples of illuminance information, flowering period information, and information about plants suitable for cultivation in the target planting location, displayed by the CPU 11 on the display unit 16. In FIG. 8A, when the user designates plant C, which blooms in summer, as the desired plant, the measured illuminance is 1,000 lux, which is too dark for plant C, which blooms in summer. The display unit 16 displays a message indicating that the illuminance is 1,200 to 2,500 lux, which is suitable for cultivating plant C. In Fig. 8B, when the user specifies plant C, which blooms in summer, as the plant they wish to cultivate, the illuminance is measured to be 1000 lux, and a message is displayed on display unit 16 indicating that an additional illuminance of 200 to 1500 lux is required to cultivate plant C, which blooms in summer. In Fig. 8C, when the illuminance is measured to be 1500 lux, and the user specifies plant D, which blooms in spring, as the plant they wish to cultivate, the message is displayed on display unit 16 indicating that it is too dark to cultivate plant D, which blooms in spring, and that an illuminance suitable for cultivating plant D is 800 to 1200 lux.

[0050] As shown in Figures 8 to 8C, the CPU 11 presents information on the illuminance that is either too much or too little for the cultivation of a specified plant at the planting location where the illuminance was measured, thereby providing the user using the illuminance meter 1 with information on the illuminance that will be sufficient for the cultivation of the specified plant at the planting location.

[0051] In the above-described embodiment, an example has been shown in which the plant information database 110 is stored inside the illuminance meter 1, but the plant information database 110 may also be located outside the illuminance meter 1. FIG. 9 is a diagram illustrating an overview of an illuminance meter and a plant information database according to an embodiment of the present disclosure. If the illuminance meter 1 is equipped with a communication function, the illuminance meter 1 can refer to the plant information database 110 via a wireless communication line. Furthermore, since the plant information database 110 is located outside the illuminance meter 1, when the contents of the plant information database 110 are updated, the illuminance meter 1 can obtain the latest information from the plant information database 110. Furthermore, since the plant information database 110 is located outside the illuminance meter 1, updating the contents of the plant information database 110 becomes easier.

[0052] FIG. 10 is a block diagram showing an example of the functional configuration of the illuminance meter 1.

[0053] 10, the illuminance meter 1 has, as its functional components, an illuminance measurement unit 101, a temperature information acquisition unit 102, an information presentation unit 103, and a communication unit 105. Each functional component is realized by the CPU 11 reading and executing an information presentation program stored in the ROM 12 or the storage 14. Since the illuminance measurement unit 101, the temperature information acquisition unit 102, and the information presentation unit 103 have already been described, only the communication unit 105 will be described here.

[0054] The communication unit 105 communicates with the plant information database 110 to acquire information stored in the plant information database 110 .

[0055] The information presentation unit 103 can measure the illuminance based on the information obtained from the plant information database 110 by communicating with the plant information database 110 via the communication unit 105, and present on the display unit 16 information about plants that can be grown in the planting location for which temperature information has been obtained.

[0056] As described above, according to the embodiments of the present disclosure, an illuminance meter 1 is provided that measures illuminance and displays information about plants suitable for cultivation in a location for which temperature information has been acquired through user selection.

Furthermore, the illuminance meter 1 according to the embodiments of the present disclosure measures illuminance and, as needed, acquires information about flowering time and temperature information to display information about plants suitable for cultivation in that location, thereby providing garden designers with information about which plants should be cultivated in that location. The use of the illuminance meter 1 according to the embodiments of the present disclosure makes it possible to provide information about plant cultivation to individuals, commercial planters, and other locations where people who wanted to enjoy plants but had previously given up due to inadequate growing conditions.

[0057] Although the embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, the technical scope of the present disclosure is not limited to such examples. It is clear that a person skilled in the art of the present disclosure can conceive of various modifications or alterations within the scope of the technical idea described in the claims, and it is understood that these modifications or alterations also naturally fall within the technical scope of the present disclosure.

In other words, the technology according to the present disclosure may achieve other effects that are obvious to a person skilled in the art of the present disclosure from the description in the above embodiments, in addition to or instead of the effects described in the above embodiments.

[0059] In the above embodiments, the information presentation process executed by the CPU after reading the software (program) may be executed by various processors other than the CPU. Examples of such processors include programmable logic devices (PLDs) such as field-programmable gate arrays (FPGAs), whose circuit configuration can be changed after fabrication, and application-specific integrated circuits (ASICs), which are dedicated electrical circuits that are processors with circuit configurations specifically designed to execute specific processes. The information presentation process may be executed by one of these processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, or a combination of a CPU and an FPGA). The hardware structure of these processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor devices.

[0060] In addition, in each of the above embodiments, the information presentation processing program is pre-stored (installed) in a ROM or storage, but this is not limiting.
