[0026] In addition, the embodiments described below are all used to illustrate general or specific examples. The numerical values, shapes, materials, structural elements, configuration positions and connection methods of structural elements, steps, and the order of steps shown in the following embodiments are examples, and their purpose is not to limit the present disclosure. In addition, among the structural elements of the following embodiments, the structural elements not described in the independent claims are described as arbitrary structural elements.

[0027] In addition, each figure is a schematic diagram, and does not necessarily illustrate strictly. In addition, in each figure, the same reference numeral is attached|subjected to the same component.

[0028] Hereinafter, the embodiments will be described in detail with reference to the drawings.

[0029] (Implementation Method)

[0030] <Summary>

[0031] For example, if multiple lighting fixtures are arranged in passages, squares, facilities, etc., and affordance lighting is performed by adjusting the lighting method of the light emitted from the lighting fixtures, it is possible to expect the effect of guiding pedestrians in a specified direction, or concentrating the guided pedestrians in a specified area, or guiding the pedestrians concentrated in a specified area to disperse. For example, the following savanna effect is known: pedestrians are guided to places with bright vertical illumination compared to places with dark vertical illumination. Since affordance lighting is mainly used to illuminate the ground, it is strictly speaking different from the savanna effect related to vertical illumination, but it is possible to change the control state of the specified illumination mode of light with the goal of producing an effect similar to the savanna effect, and to mobilize the emotions of pedestrians through the savanna effect, thereby guiding pedestrians.

[0032] Here, the illumination mode refers to a scene in which available lighting is performed that is different from a simple normal lighting scene. The illumination mode in which available lighting is performed is realized, for example, by a dynamic control signal such as repeatedly increasing or decreasing the output of light. The control state of changing the illumination mode refers to a situation in which available lighting is performed from a simple normal lighting scene or when it is turned off, a situation in which other available lighting is performed from available lighting, or a situation in which a simple normal lighting scene or when it is turned off is performed from available lighting. Increasing or decreasing the output of light refers to an increase or decrease in the brightness and illuminance of light emitted by a lighting fixture, an increase or decrease in the brightness and illuminance of light irradiated to an illuminated surface, a change in the color temperature or chromaticity of light emitted by a lighting fixture, and a change in the color temperature or chromaticity of light irradiated to an illuminated surface. As an example of available lighting, a plurality of lighting fixtures are arranged along a passage, and the illuminance and chromaticity of light irradiated to an illuminated surface (light irradiation area) are gradually changed from one side of the passage to the other side or from the other side to one side.

[0033] <Structure and Function>

[0034] use Figure 1 to Figure 3 , a lighting simulation system 1 including a lighting control simulation device 10 according to the following embodiment will be described.

[0035] Figure 1 It is a block diagram showing a lighting simulation system 1 according to the embodiment. Figure 2 It is a graph showing various data. Figure 3 is a diagram showing the simulation results. Figure 3 In the figure, pedestrians are represented by black circles or white circles, and pedestrian flows are represented by dotted lines or dash-dot lines.

[0036] like Figure 1 As shown, the lighting simulation system 1 of the present embodiment is a system that virtually performs available lighting that can guide pedestrians (people) by adjusting the lighting method of light emitted from lighting fixtures, thereby simulating how the flow of pedestrians changes. The lighting simulation system 1 is, for example, a PC (Personal Computer) equipped with a display unit 20 such as a liquid crystal display and an input unit 5 such as a keyboard, and a dedicated tablet terminal.

[0037] This type of lighting simulation system 1 performs simulation of a place where people are to be guided, such as a store, a park, an amusement park, a station, a large-scale facility, and the like.

[0038] The lighting simulation system 1 includes an input unit 5 , a lighting control simulation device 10 , and a display unit 20 .

[0039] [Input unit 5]

[0040] The input unit 5 is an input interface such as a keyboard or a pointing device that can input various data to the lighting control simulation device 10. The various data include at least Figure 1 The road map data shown, such as Figure 2 The various data may include pedestrian data, lighting fixture specification data, and lighting irradiation pattern data shown in (a) to (e) of FIG. 1 . In addition, the various data may include pedestrian frequency data and vehicle frequency data.

[0041] The road map data indicates the planned installation location of the lighting fixture and the surrounding area of ​​the planned installation location. On the road map data, a virtual lighting fixture can be configured to overlap the virtual lighting fixture with the road map data. Since the road map data shows the location information such as latitude and longitude, when the virtual lighting fixture is configured on the road map data, the configured location information can be associated with the virtual lighting fixture.

[0042] Pedestrian data represents the attributes of pedestrians. The attributes of pedestrians include the gender of pedestrians, the age group of pedestrians, the occupation of pedestrians, etc. For example, the attributes of pedestrians are students going to and from school, company employees commuting, shopping, walking, couriers, police patrols, etc.

[0043] In addition, in addition to pedestrian data, various data may also include mobile vehicle attribute data. Mobile vehicle attribute data represents the attributes of a mobile vehicle. The attributes of a mobile vehicle include vehicle type, vehicle form, etc. For example, the attributes of a mobile vehicle include a bus, a private car, a taxi, a business delivery vehicle, an ambulance, a patrol car, and a fire truck.

[0044] The lighting fixture specification data indicates the specifications related to illumination of the lighting fixture to be installed at the scheduled installation location. The specifications related to illumination of the lighting fixture include the color temperature, installation location, product number, etc. of the lighting fixture.

[0045] The lighting irradiation pattern data represents a plurality of irradiation patterns for irradiating light from a lighting fixture. The irradiation pattern is composed of a combination of the setting of the illuminance of the irradiation point when the lighting fixture irradiates light to the irradiated surface, the setting of whether the light emitted by the lighting fixture flickers or not, the setting of the time interval when flickering, the setting of the light color of the lighting fixture, the setting of whether the irradiation point is fixed or moved, and the setting of setting the irradiation position range and the moving speed to a fixed value or a variable value when the irradiation point moves. In addition, in the setting of the irradiation pattern, the lighting fixture to be used can be specified. Therefore, the lighting irradiation pattern data also includes the lighting fixture to be used.

[0046] Pedestrian frequency data indicates the time period when the pedestrian frequency (traffic volume) is higher than the reference value. For example, the pedestrian frequency data indicates the pedestrian frequency at each time period when the pedestrian frequency at a specified location is higher than the reference value, or may only include time periods with a specified frequency higher than the reference value. The reference value is a pre-set value and can be changed arbitrarily.

[0047] The vehicle frequency data indicates the time period when the frequency (traffic volume) of vehicles other than pedestrians is higher than the reference value. For example, the vehicle frequency data indicates the frequency of vehicles at each time period when the frequency of vehicles at a specified location is higher than the reference value, or may only include time periods with a frequency higher than the specified value. The reference value is a pre-set value and can be changed arbitrarily.

[0048] In addition, the pedestrian traffic frequency data and the vehicle traffic frequency data may be input to the input unit 5 , or the pedestrian traffic frequency data and the vehicle traffic frequency data may not be input to the input unit 5 .

[0049] like Figure 1 As shown, the input unit 5 outputs various input data to the lighting control simulation device 10 .

[0050] [Lighting control simulation device 10]

[0051] The lighting control simulation device 10 acquires various data from the input unit 5. The lighting control simulation device 10 stores the acquired various data in the first storage unit 11a to the sixth storage unit 11f respectively corresponding to each other.

[0052] The lighting control simulation device 10 simulates the effect of the lighting fixture on pedestrians based on the conditions (various data) of the predetermined installation location of the lighting fixture and the surrounding area of ​​the predetermined installation location. For example, the lighting control simulation device 10 configures a virtual lighting fixture capable of performing available lighting at the predetermined installation location on the road map data, or inputs various data such as the conditions of the predetermined installation location and the surrounding area of ​​the predetermined installation location, thereby simulating the effect of the lighting fixture on pedestrians.

[0053] Specifically, the lighting control simulation device 10 includes a first storage unit 11 a to a sixth storage unit 11 f and a processing unit 12 .

[0054] like Figure 1 and Figure 2 As shown, the first storage unit 11a stores road map data. If new road map data is acquired, the first storage unit 11a can update and store the road map data.

[0055] The second storage unit 11 b stores pedestrian data of each of a plurality of pedestrians. If new pedestrian data is acquired, the second storage unit 11 b can update and store the pedestrian data.

[0056] The third storage unit 11c stores lighting fixture specification data of each of the plurality of lighting fixtures. If the lighting fixture specification data is acquired, the third storage unit 11c can update the lighting fixture specification data.

[0057] The fourth storage unit 11d stores the illumination irradiation pattern data. When the illumination irradiation pattern data is acquired, the fourth storage unit 11d can update and store the illumination irradiation pattern data.

[0058] The fifth storage unit 11 e stores pedestrian frequency pattern data. If the pedestrian frequency pattern data is acquired, the fifth storage unit 11 e can update and store the pedestrian frequency pattern data.

[0059] The sixth storage unit 11f stores the vehicle traffic frequency pattern data. When the vehicle traffic frequency pattern data is acquired, the sixth storage unit 11f can update and store the vehicle traffic frequency pattern data.

[0060] In addition, the first storage unit 11 a to the sixth storage unit 11 f may be one storage unit.

[0061] In addition, various data in the first storage unit 11a to the sixth storage unit 11f can be updated by inputting from the input unit 5. In addition, various data in the first storage unit 11a to the fourth storage unit 11d can be updated by periodically or temporarily (manually) downloading road map data, pedestrian data, lighting equipment specification data, and lighting irradiation pattern data from a predetermined external device 9. In addition, various data in the fifth storage unit 11e and the sixth storage unit 11f can also be updated by periodically or temporarily downloading pedestrian traffic frequency pattern data and vehicle traffic frequency pattern data from a predetermined external device 9.

[0062] The processing unit 12 can obtain simulation results that predict how the flow of pedestrians in the planned installation location and the surrounding area changes.

[0063] Specifically, the processing unit 12 virtually sets where on the road map data the lighting fixture is to be installed based on the various data input to the input unit 5. When the processing unit 12 virtually sets where on the road map data the lighting fixture is to be installed, the processing unit 12 obtains a simulation result that predicts how the flow of pedestrians in the predetermined installation location and the surrounding area changes by using at least the lighting fixture specification data and / or the lighting irradiation pattern data.

[0064] For example, when the processing unit 12 virtually sets where on the road map data the lighting fixture is to be installed, the processing unit 12 uses an artificial intelligence simulation algorithm to perform a simulation to predict how the flow of pedestrians in the predetermined installation location and the surrounding area will change, based at least on the location information of the virtually installed lighting fixture, and the lighting fixture specification data and / or the lighting illumination pattern data, to obtain a simulation result. The artificial intelligence simulation algorithm may also be a learning model obtained by mechanically learning past sample data. The past sample data may also be training data for learning changes in the flow of pedestrians based on at least the virtual installation location of the lighting fixture, and the lighting fixture specification data and / or the lighting illumination pattern data. The learning of the artificial intelligence simulation algorithm may also be performed using one or more statistically known classification techniques. In addition, the processing unit 12 may also update the simulation algorithm by receiving feedback of the simulation results.

[0065] In addition, when pedestrian frequency data and vehicle frequency data are input as various data from the input unit 5, a simulation result predicting how the flow of pedestrians in the predetermined installation location and the surrounding area changes may be obtained. In this case, when the processing unit 12 virtually sets where the lighting fixture is to be installed on the road map data, it may perform a simulation predicting how the flow of pedestrians in the predetermined installation location and the surrounding area changes based on the lighting fixture specification data and / or lighting irradiation pattern data, pedestrian frequency data, and vehicle frequency data, and obtain a simulation result using an artificial intelligence simulation algorithm.

[0066] Then, the processing unit 12 outputs the acquired simulation result to the display unit 20 .

[0067] In addition, the processing unit 12 also obtains the result of simulating the following matters: in the behavior of multiple pedestrians when the illumination mode is executed, compared with the behavior of pedestrians when the illumination mode is not executed, the proportion of pedestrians among the multiple pedestrians can be guided. That is, the processing unit 12 obtains the simulation result (hereinafter referred to as the first simulation result) predicting how the above-mentioned pedestrian flow changes, and the simulation result (hereinafter referred to as the second simulation result) simulating the proportion of pedestrians among the multiple pedestrians that can be guided. The processing unit 12 outputs these two simulation results to the display unit 20.

[0068] In addition, if Figure 3 As shown, the processing unit 12 may also display an image obtained by graphing the number of customers attracted to the store before and after the introduction of the lighting fixtures capable of performing affordance lighting on the display unit 20. In addition, the processing unit 12 may also display the change in pedestrian flow before the introduction of affordance lighting and the change in pedestrian flow after the introduction of affordance lighting on the display unit 20 as simulation results.

[0069] [Display unit 20]

[0070] like Figure 1 and Figure 3 As shown, the display unit 20 is a display such as a liquid crystal display, an organic EL (Electro Luminescence) display. The display unit 20 obtains the simulation result from the processing unit 12. When the first simulation result is obtained, the display unit 20 displays the first simulation result. In addition, when the second simulation result is obtained, the display unit 20 displays the second simulation result. In addition, when the display unit 20 obtains the first simulation result and the second simulation result at the same time, the first simulation result and the second simulation result may be combined and displayed.

[0071] <Processing Action>

[0072] The processing operations of the lighting control simulation device 10 and the lighting control simulation method according to the present embodiment will be described.

[0073] (Action Example)

[0074] In this example, use Figure 4 Provide explanation. Figure 4 This is a flowchart showing an operation example of the lighting control simulation device 10 according to the embodiment.

[0075] like Figure 4As shown, first, the lighting simulation system 1 is started up, and a simulation program of the lighting simulation system 1 is executed. As a result, a user interface that allows input of various data is displayed on the display unit 20.

[0076] The input unit 5 is input with various data (S11). That is, the input unit 5 receives at least road map data, pedestrian data, lighting equipment specification data, and lighting irradiation pattern data as various data. In addition, the input unit 5 may also receive pedestrian frequency data and vehicle frequency data as various data. The input unit 5 outputs the input various data to the lighting control simulation device 10.

[0077] Next, the operator uses the input unit 5 to virtually arrange lighting fixtures on the road map data displayed on the display unit 20. Thus, the processing unit 12 virtually sets where the lighting fixtures are to be installed on the road map data based on the various data input to the input unit 5 and the virtual arrangement of the lighting fixtures on the road map data (S12).

[0078] Next, when the processing unit 12 virtually sets where the lighting fixture is to be installed on the road map data, the processing unit 12 obtains a simulation result predicting how the flow of pedestrians in the predetermined installation location and the surrounding area changes by using at least the lighting fixture specification data and / or the lighting illumination pattern data (S13). For example, the processing unit 12 uses an artificial intelligence simulation algorithm based on the location information of the lighting fixture virtually installed on the road map data, the lighting fixture specification data and / or the lighting illumination pattern data, to perform a simulation predicting how the flow of pedestrians in the predetermined installation location and the surrounding area changes, and obtains a simulation result (a first simulation result).

[0079] In addition, the processing unit 12 may also obtain a result (second simulation result) obtained by simulating the following matters: in the behavior of multiple pedestrians when the illumination mode is executed, compared with the behavior of pedestrians when the illumination mode is not executed, the proportion of pedestrians among the multiple pedestrians can be guided. In other words, the processing unit 12 may also obtain the first simulation result and the second simulation result. The processing unit 12 may also output these two simulation results to the display unit 20.

[0080] Next, the processing unit 12 outputs the simulation result to the display unit 20 (S14). Figure 3 As shown, when the display unit 20 obtains the simulation result from the processing unit 12, the obtained simulation result is displayed. When only the first simulation result is obtained, the display unit 20 only displays the first simulation result. When the second simulation result is also obtained, the display unit 20 may display the first simulation result and the second simulation result in combination. In addition, when only the second simulation result is obtained, the display unit 20 may only display the second simulation result.

[0081] Then, the lighting simulation system 1 ends Figure 4 The processing actions of the flowchart shown.

[0082] <Effects>

[0083] Next, the effects of the lighting control simulation device 10 and the lighting control simulation method according to the present embodiment will be described.

[0084] As described above, the lighting control simulation device 10 involved in the present embodiment simulates the effect of the lighting fixture on pedestrians based on the conditions of the predetermined installation location of the lighting fixture and the surrounding area of ​​the predetermined installation location. The lighting control simulation device 10 includes a processing unit 12, which is input with road map data representing the predetermined installation location of the lighting fixture and the surrounding area, pedestrian data representing attributes of pedestrians, lighting fixture specification data representing specifications related to illumination of the lighting fixture predetermined to be installed at the predetermined installation location, and lighting illumination pattern data representing multiple illumination modes of light irradiated from the lighting fixture. The processing unit 12 virtually sets where the lighting fixture is to be installed on the road map data, and obtains a simulation result that predicts how the flow of pedestrians in the predetermined installation location and the surrounding area changes by using the lighting fixture specification data and / or the lighting illumination pattern data.

[0085] Accordingly, by inputting the planned installation location, the surrounding area of ​​the planned installation location, pedestrian data, lighting equipment specification data, and lighting irradiation pattern data, it is possible to simulate the flow of pedestrians when lighting equipment that can perform available lighting is introduced.

[0086] Therefore, according to the lighting control simulation device 10, it is possible to simulate in advance the effects that can be expected when a lighting fixture capable of performing availability lighting is introduced.

[0087] In addition, the lighting control simulation method involved in the present embodiment simulates the effect of the lighting fixture on pedestrians based on the conditions of the scheduled installation location of the lighting fixture and the surrounding area of ​​the scheduled installation location. The lighting control simulation method includes the following processing: road map data representing the scheduled installation location of the lighting fixture and the surrounding area, pedestrian data representing attributes of pedestrians, lighting fixture specification data representing specifications related to illumination of the lighting fixture scheduled to be installed at the scheduled installation location, and lighting illumination pattern data representing multiple illumination modes of irradiating light from the lighting fixture are input, where the lighting fixture is to be installed on the road map data is virtually set, and by using the lighting fixture specification data and / or the lighting illumination pattern data, a simulation result predicting how the flow of pedestrians in the scheduled installation location and the surrounding area changes is obtained.

[0088] According to this, the same effects as described above are also exerted in the lighting control simulation method.

[0089] In addition, in the lighting control simulation device 10 involved in the present embodiment, the processing unit 12 also obtains the results obtained by simulating the following matters: in the behavior of multiple pedestrians when the illumination mode is executed, compared with the behavior of multiple pedestrians when the illumination mode is not executed, what proportion of pedestrians among the multiple pedestrians can be guided.

[0090] Based on this, the predicted effect of pedestrian flow guidance achieved by the availability lighting can be known as a judgment material before installing the lighting fixtures. If the predicted effect is lower than expected, the configuration of the lighting fixtures and the selection of the illumination mode that meet the expectations can be considered before the installation of the lighting fixtures.

[0091] In addition, the lighting control simulation device 10 involved in this embodiment obtains a simulation result that predicts how the pedestrian flow in the predetermined setting location and the surrounding area changes by also inputting pedestrian frequency data representing the time period when the pedestrian frequency is higher than the reference value, and vehicle frequency data representing the time period when the vehicle frequency other than pedestrians is higher than the reference value.

[0092] For example, if the simulation is performed in all time periods, the processing load of the lighting control simulation device 10 may increase, and it may take a long time to obtain the simulation results.

[0093] However, according to the present embodiment, for example, the simulation can be performed in a shorter time by focusing on a dangerous time period when the traffic volume is high and a traffic accident may occur.

[0094] In particular, in the case of a system that performs simulation by means of calculations of a remote external device 9 such as a cloud server, by limiting the calculations to important ones, it is possible to suppress overloads of calculations and communications.

[0095] In the lighting control simulation device 10 according to the present embodiment, the irradiation mode is composed of a combination of the setting of the illuminance of the irradiation point, the setting of whether to flash or not, the setting of the time interval when flashing, the setting of the luminous color, and the setting of the irradiation position range and the moving speed to a fixed value or a variable value when the irradiation point moves. Furthermore, the lighting fixture to be used can be specified in the setting of the irradiation mode.

[0096] According to this, various illumination patterns can be generated by changing the settings. Therefore, even if each pedestrian has a variety of preferences, an illumination pattern suitable for the pedestrian can be provided. As a result, pedestrian data can be enriched, so a simulation result with better accuracy can be obtained.

[0097] Furthermore, the lighting control simulation device 10 according to the present embodiment can periodically or temporarily download and update at least road map data, pedestrian data, lighting equipment specification data, and lighting irradiation pattern data from a predetermined external device 9 .

[0098] According to this, the latest various data can be automatically or temporarily updated, so it is possible to suppress a decrease in the accuracy of the simulation result and make the result realistic.

[0099] (Variation of the embodiment)

[0100] The lighting control simulation device 10a and the lighting control simulation method of this variant are different from the lighting control simulation device and the lighting control simulation method of the embodiment in that the communication unit 12a is used instead of the processing unit. Regarding the structure and function of the lighting control simulation device 10a and the lighting control simulation method of this variant, the same reference numerals are given to the same structure and function as the structure and function of the lighting control simulation device 10 and the lighting control simulation method of the embodiment, and detailed description of the structure and function is omitted.

[0101] <Structure and Function>

[0102] use Figure 5 , a lighting control simulation device 10a and a lighting control simulation method according to this variation will be described.

[0103] Figure 5 It is a block diagram showing a lighting control simulation device 10 a according to a modification of the embodiment.

[0104] In the present modification, the lighting control simulation device 10a includes a communication unit 12a in addition to the first storage unit 11a to the sixth storage unit 11f.

[0105] The communication unit 12a sends various data input to the input unit 5 to an external device 9 such as a cloud server. That is, the communication unit 12a entrusts the external device 9 to perform a simulation to predict how the flow of pedestrians in the predetermined setting place and the surrounding area will change based on the various data input to the input unit 5 and the virtual setting position (position information) of the lighting fixture on the road map data input to the input unit 5. The external device 9 performs a simulation to predict how the flow of pedestrians in the predetermined setting place and the surrounding area will change, and sends the result of the performed simulation to the communication unit 12a. Thus, the communication unit 12a receives (acquires) the simulation result from the external device 9. The communication unit 12a outputs the acquired simulation result to the display unit 20.

[0106] <Effects>

[0107] Next, the effects of the lighting control simulation device 10a and the lighting control simulation method according to this modification will be described.

[0108] As described above, in the lighting control simulation device 10a according to the present modification, the processing unit is a communication unit 12a capable of communicating with the external device 9. The external device 9 is commissioned to perform a simulation for predicting how the flow of pedestrians in the predetermined installation location and the surrounding area will change, and the result of the commissioned simulation is obtained from the external device 9.

[0109] According to this, by causing the external device 9 to analyze the influence of the illumination pattern on pedestrians, it is possible to suppress an increase in the processing load of the lighting control simulation device 10 a.

[0110] (Other modifications, etc.)

[0111] As mentioned above, although this disclosure was demonstrated based on embodiment and the modification example of embodiment, this disclosure is not limited to these embodiment and the modification example of embodiment, etc.

[0112] For example, in the lighting control simulation device and the lighting control simulation method of the present embodiment and the modified example of the embodiment, the lighting control simulation method may be realized by a program executed by a computer.
