[Modes for carrying out the invention]

[0013] The following describes the environmental control equipment placement proposal system and environmental control equipment placement proposal method related to this disclosure, using drawings.

[0014] Embodiment 1. Figure 1 is a schematic diagram showing an environmental adjustment equipment placement suggestion system according to Embodiment 1 of the present disclosure. As shown in Figure 1, the environmental adjustment equipment placement suggestion system 100 according to Embodiment 1 of the present disclosure comprises a data acquisition unit 1 and an inference unit 2. As shown in Figure 1, the inference unit 2 is connected to a trained model storage unit 3.

[0015] The data acquisition unit 1 acquires spatial information and environmental control equipment information, which is information on environmental control equipment. The space in the present disclosure is, for example, one room space inside a building, a space where people stay, a server room, a machine room, a factory, a warehouse, etc. The spatial information is information on the space where environmental control equipment for adjusting the internal environment of the space is provided, and is information capable of discriminating at least the shape and size of the space. The spatial information is, for example, information including at least any one of a drawing (2D, 3D) of the space, BIM (Building Information Modeling) data indicating the material of the members forming the space, the use of the space, and the number of people using the space. The BIM data includes, for example, materials, specifications of members, performance, cost, etc. Further, the spatial information may include, as more detailed information, at least any one of the position of furniture provided in the space, the position of people staying in the space, and the position of windows in the space. Note that the space does not necessarily have to be an enclosed space, and may be an area for which one environmental adjustment is to be performed.

[0016] The environmental control equipment is, for example, an air conditioner, a humidifier, a ventilation device, a blower, an air cleaner, a deodorizer, lighting, a soundproofing machine, a speaker, etc. The environmental control equipment information may be information including the specifications of these environmental control equipment, and may include at least any one of the dimensions and the number of environmental control equipment provided in the space. In the case of a ventilation device, the environmental control equipment information may include, for example, at least any one of the position of the air outlet, the position of the air inlet, the air volume, the air velocity, the air age, and the temperature conversion efficiency. In the case of an air conditioner, the environmental control equipment information may include, for example, at least any one of the position of the air outlet, the position of the air inlet, the air volume, the air velocity, and the temperature of the air outlet. In the case of lighting, the environmental control equipment information may include, for example, at least any one of the optical axis, the distribution of the irradiation amount inside the space, and the emission color of the lighting.

[0017] The inference unit 2 outputs the arrangement information from the space information acquired by the data acquisition unit 1 and the environmental control device information, using the learned model storage unit 3 that infers the arrangement information indicating the position where the environmental control device is arranged in the space from the space information and the environmental control device information acquired by the data acquisition unit 1.

[0018] FIG. 2 is a schematic configuration diagram showing the hardware configuration of the environmental control device arrangement proposal system according to Embodiment 1 of the present disclosure. The computer 22 includes, for example, a CPU 23, a main memory device 24, and an auxiliary storage device 25. The main memory device 24 may be a storage medium such as a RAM, and the auxiliary storage device 25 may be a ROM. The environmental control device arrangement proposal system 100 according to Embodiment 1 of the present disclosure may, for example, provide the data acquisition unit 1 and the inference unit 2 in the main memory device 24, and provide the learned model storage unit 3 in the auxiliary storage device 25. The computer 22 is provided with an input device 21 and an output device 28 externally. The input device 21 is, for example, a mouse or a keyboard. The data acquisition unit 1 may acquire the space information and the environmental control device information input by the designer to the input device 21. Further, the output device 28 includes, for example, a display monitor that displays the output result from the computer 22. The arrangement information output by the inference unit 2 is displayed on the output device 28. Also, as shown in FIG. 2, the computer 22 is connected to an external storage device 27 via a network 26 and acquires information necessary for calculation from an external recording medium. Further, the computer 22 may be able to save the inference result to an external storage medium.

[0019] In FIG. 2, an example where the inference unit 2 and the learned model storage unit 3 are provided in the computer 22 is shown, but the inference unit 2 and the learned model may be in the cloud on the network. By the user uploading the space information and the environmental control device information using a mobile terminal or the like, the environmental control device arrangement proposal system 100 can obtain the arrangement information.

[0020] Figure 3 is a schematic diagram showing a learning device that generates a trained model 3 used in the environmental adjustment equipment placement proposal system according to Embodiment 1 of this disclosure. The learning device 5 comprises a data acquisition unit 11 and a model generation unit 4. The data acquisition unit 11 acquires spatial information and environmental adjustment equipment information. The model generation unit 4 learns placement information using training data created based on the combination of spatial information and environmental adjustment equipment information output from the data acquisition unit 11. In other words, the environmental adjustment equipment placement proposal system according to Embodiment 1 of this disclosure generates a trained model storage unit 3 that infers placement information from spatial information and environmental adjustment equipment information.

[0021] The model generation unit 4 can use any known learning algorithm, such as supervised learning, unsupervised learning, or reinforcement learning. As an example, we will explain the case where the K-means clustering method, which is an unsupervised learning method, is applied. Unsupervised learning is a method in which a learning device learns features from training data that does not contain results (labels).

[0022] The model generation unit 4 learns placement information through so-called unsupervised learning, for example, following a grouping method using the K-means method. The K-means method is a non-hierarchical clustering algorithm that uses the mean of the clusters to classify a given number of clusters into k. Specifically, the K-means method is processed in the following manner: First, each data xi is randomly assigned to a cluster. Next, the center Vj of each cluster is calculated based on the assigned data. Here, i is an arbitrary number assigned to each data, and j is an arbitrary number assigned to each cluster. Next, the distance between each xi and each Vj is calculated, and xi is reassigned to the cluster with the closest center. Finally, if the cluster assignment of all xi does not change after the above process, or if the amount of change falls below a predetermined threshold, it is determined that convergence has occurred and the process is terminated.

[0023] As described above, the environmental adjustment equipment placement proposal system 100 according to Embodiment 1 of this disclosure learns placement information by so-called unsupervised learning, according to training data created based on a combination of spatial information and environmental adjustment equipment information acquired by the data acquisition unit 11. The model generation unit 4 generates and outputs a trained model by performing the above-described learning. The trained model storage unit 3 stores the trained model output from the model generation unit 4. When using supervised learning or the like, the combination of spatial information and environmental adjustment equipment information is learned using the already outputted placement information as the correct data.

[0024] In implementing unsupervised learning as described in this disclosure, the method is not limited to non-hierarchical clustering using the k-means method as described above; any other known method capable of clustering is acceptable. For example, hierarchical clustering such as the shortest distance method may also be used.

[0025] This disclosure describes the case where unsupervised learning is applied to the learning algorithm used by the model generation unit and inference unit, but it is not limited to this. In addition to unsupervised learning, reinforcement learning, supervised learning, semi-supervised learning, deep learning, etc., can also be applied to the learning algorithm.

[0026] Figure 4 is a flowchart illustrating a method for proposing the arrangement of environmental control equipment according to Embodiment 1 of this disclosure. As shown in Figure 4, in step S1, the data acquisition unit 11 acquires spatial information and environmental control equipment information. Here, the means by which the data acquisition unit 1 acquires spatial information and environmental control equipment information may be arbitrarily input by the equipment designer, or spatial information included in the output data of a system such as CAD may be input directly. In addition, the environmental control equipment information may be automatically input from a separately connected system. At this time, the spatial information and environmental control equipment information acquired by the data acquisition unit 1 are transmitted to the inference unit 2.

[0027] In step S2, the inference unit 2 uses the trained model storage unit 3 to infer placement information from spatial information and environmental control equipment information. Placement information is information indicating the position where environmental control equipment is placed in space, and includes, for example, at least one of the specifications, dimensions, and number of environmental control equipment. Placement information may also include at least one of the wind direction and wind speed of the environmental control equipment. Furthermore, placement information may be in the form of a combination of the coordinates of the equipment placed in the input two-dimensional drawing, or a combination of space and equipment in a three-dimensional model, etc.

[0028] In step S3, the inference unit 2 outputs the inferred placement information, which is generated using the trained model storage unit 3, to an output device 28 or the like. The destination for the placement information output may be a BIM system or a simulator that outputs information other than placement information.

[0029] Accordingly, the method for proposing the placement of environmental adjustment equipment according to Embodiment 1 of the present disclosure comprises the steps of: a data acquisition unit 1 acquiring spatial information, which is information about the space in which environmental adjustment equipment for adjusting the internal environment of the space is provided, and environmental adjustment equipment information, which is information about the environmental adjustment equipment provided in the space; an inference unit 2 using a trained model that infers placement information, which is information indicating the position in which the environmental adjustment equipment is placed in the space, from the spatial information and environmental adjustment equipment information acquired by the data acquisition unit, to infer placement information from the spatial information and environmental adjustment equipment information acquired by the data acquisition unit; and an inference unit 2 outputting placement information.

[0031] The environmental control equipment placement proposal system 100 and environmental control equipment placement proposal method according to Embodiment 1 of this disclosure output placement information from spatial information and environmental control equipment information acquired by the data acquisition unit using a trained model storage unit 3, so that the optimal placement of environmental control equipment can be proposed even if the designer does not have the knowledge or skills necessary for simulation.

[0032] Furthermore, the environmental adjustment equipment placement proposal system 100 according to Embodiment 1 of this disclosure uses a trained model storage unit 3 to output placement information from spatial information and environmental adjustment equipment information acquired by the data acquisition unit, thereby reducing the computational load compared to conventional systems that output placement information using a simulator.

[0033] Furthermore, the environmental adjustment equipment placement proposal system 100 according to Embodiment 1 of this disclosure uses a trained model storage unit 3 to output placement information from spatial information and environmental adjustment equipment information acquired by the data acquisition unit, thereby reducing the time and man-hours required for creating a model for simulation, inputting calculation conditions, and waiting for calculation time.

Therefore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure can output placement information that reflects detailed spatial information. This makes it easy for designers to incorporate environmental control equipment into design drawings.

[0035] Furthermore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure infers placement information from spatial information including at least one of the following: the position of furniture installed in the space, the position of people staying in the space, and the position of windows in the space.

This makes it easier for designers to incorporate environmental control equipment into their design drawings.

[0036] Furthermore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure infers placement information from environmental control equipment information that includes at least one of the dimensions and number of environmental control equipment to be installed in the space.

This makes it easy for designers to reflect environmental control equipment in design drawings.

[0037] Furthermore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure infers placement information from environmental control equipment information including at least one of the following: the position of the ventilation device's outlet, the position of the intake, airflow, wind speed, air age, and temperature conversion efficiency. Therefore, when the ventilation device is actually operated, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure can distribute airflow throughout the entire space or eliminate stagnant air in specific locations, thereby delivering fresh air to users in the space.

[0038] Furthermore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure infers placement information from environmental control equipment information including at least one of the following: the position of the air conditioner's outlet, the position of the air intake, the airflow rate, the wind speed, and the temperature of the air conditioner's outlet. Therefore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure can eliminate unevenness in the temperature distribution inside the space and improve the comfort of the space's users.

[0039] Furthermore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure infers placement information from environmental control equipment information that includes at least one of the optical axis, the distribution of illumination amount inside the space, and the emission color of the lighting. Therefore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure can irradiate light into areas inside the space where users may stay, thereby improving the comfort of users of the space.

[0040] Furthermore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure outputs placement information that includes at least one of the specifications, dimensions, and number of environmental control equipment. Therefore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure can output placement information that takes into account the comfort of the space user more effectively.

[0041] Furthermore, the environmental control equipment placement suggestion system 100 according to Embodiment 1 of this disclosure outputs placement information that includes at least one of the wind direction and wind speed of the environmental control equipment.

Here, the same reference numerals are used for the same components as in Embodiment 1 of this disclosure, and descriptions of the same or corresponding parts are omitted. The placement suggestion system 100a for environmental control equipment according to Embodiment 2 will now be described with reference to the drawings.

[0043] Figure 5 is a schematic diagram showing an environmental control equipment placement suggestion system according to Embodiment 2 of this disclosure. In the environmental control equipment placement suggestion system 100a according to Embodiment 2 of this disclosure, as shown in Figure 5, the data acquisition unit 1a acquires spatial information and environmental information, which is information indicating the environment inside the space. The environmental information may be information that can be adjusted by the environmental control equipment or information indicating the comfort level of the space user, and may include at least one of the following: temperature inside the space, humidity, CO2, VOC (Volatile Organic Compounds), Particulate Matter, dust, pollen, odor, virus, illuminance, and sound pressure. Furthermore, the environmental information may include at least one of the following: outside temperature, solar radiation conditions, number of heat sources inside the space, location of heat sources inside the space, number of CO2 sources, and location of CO2 sources.

The inference unit 2a and trained model may reside in a cloud on a network. By uploading spatial information and environmental information to the cloud using a mobile terminal or the like, the environmental adjustment equipment placement suggestion system 100a can output placement information.

[0045] Figure 6 is a schematic diagram showing a learning device that generates a trained model 3a used in the environmental adjustment equipment placement proposal system according to Embodiment 2 of this disclosure. As shown in Figure 6, the data acquisition unit 11a acquires spatial information and environmental information.

Therefore, similar to Embodiment 1, it is possible to propose the optimal placement of environmental control equipment even if the designer does not possess the knowledge or skills necessary for simulation.

[0052] Furthermore, the environmental control equipment placement proposal system 100a and environmental control equipment placement proposal method according to Embodiment 2 of this disclosure infer placement information from environmental information including at least one of the following: temperature, humidity, CO2, VOCs, dust, pollen, odor, viruses, illuminance, and sound pressure inside the space.

In the environmental adjustment equipment placement suggestion system 100b according to Embodiment 3 of this disclosure, as shown in Figure 8, the data acquisition unit 1b acquires spatial information, environmental adjustment equipment information, and environmental information. The inference unit 2b uses the trained model storage unit 3b to output placement information from the spatial information, environmental adjustment equipment information, and environmental information acquired by the data acquisition unit 1b. The inference unit 2b and the trained model may reside in a cloud on a network.

As shown in Figure 9, the data acquisition unit 11b acquires spatial information, environmental adjustment equipment information, and environmental information. The model generation unit 4b learns placement information using training data created based on the combination of spatial information and environmental information output from the data acquisition unit 11b. In other words, the environmental adjustment equipment placement proposal system 100b according to Embodiment 3 of this disclosure generates a trained model storage unit 3b that infers placement information from spatial information, environmental adjustment equipment information, and environmental information.

[0057] Therefore, in the environmental adjustment equipment placement proposal system 100b according to Embodiment 3 of this disclosure, the data acquisition unit 1b acquires spatial information, environmental adjustment equipment information, and environmental information which is information indicating the environment inside the space, and the inference unit 2b uses a trained model storage unit 3b that infers placement information from the spatial information, environmental adjustment equipment information, and environmental information to output placement information from the spatial information, environmental adjustment equipment information, and environmental information acquired by the data acquisition unit.

Therefore, similar to Embodiment 1, it can propose the optimal placement of environmental adjustment equipment even if the designer does not possess the knowledge or skills necessary for simulation.
