Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, "odor" is also described as "scent" or "smell", and the former is used in a good sense, while the latter is often used in a bad sense. And in a space such as a room, "smell" is generally considered to be something to be removed. In addition to using deodorants, odor removers, anti-odor agents, etc. to remove "smell", there is also a method of masking "smell" with a fragrance.

[0005] When removing "smell" with a fragrance, it is necessary to use an appropriate fragrance according to the "smell". However, since there are a variety of fragrances, it may be difficult to use an appropriate fragrance in some cases.

[0006] In view of the above circumstances, the present invention aims to provide a diffuser, an odor control system, an information processing device, and a program that can diffuse appropriate substances such as fragrances into a space according to the odor in the space.

Means for Solving the Problems

[0007] According to one aspect of the present invention, a diffuser for diffusing a substance is provided. This diffuser comprises a detection unit, an information holding unit, a comparison unit, and a diffusion unit. The detection unit is configured to detect odors in the air using an odor sensor that includes at least a quartz crystal sensor. The information holding unit holds at least one pair of characteristic information indicating the characteristics of a target odor and substance information indicating a substance corresponding to the odor. The comparison unit is configured to compare the detection result from the detection unit with the characteristic information. The diffusion unit is configured to diffuse the substance indicated by the substance information corresponding to the characteristic information when the detection result and the characteristic information match.

[0008] According to one aspect of the present invention, it is possible to diffuse an appropriate substance into a space, such as a room, depending on the odor conditions of that space. [Brief explanation of the drawing]

[Figure 9] This is a block diagram showing the functional configuration of the information processing device 8 and the diffuser 9. [Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described below with reference to the drawings. The various features shown in the embodiments below can be combined with each other.

[0011] Incidentally, the program for implementing the software appearing in this embodiment may be provided as a computer-readable non-temporary recording medium, or it may be provided so that the program is launched on an external computer and its functions are realized on a client terminal (so-called cloud computing).

[0012] Furthermore, in this embodiment, "part" may include, for example, hardware resources implemented by circuits in a broad sense, and the information processing of software that can be specifically realized by these hardware resources. In addition, various types of information are handled in this embodiment, and these types of information can be represented, for example, by the physical values ​​of signal values ​​representing voltage and current, the high or low values ​​of signal values ​​as a set of binary bits composed of 0s or 1s, or by quantum superposition (so-called qubits), and communication and calculations can be performed on circuits in a broad sense.

[0013] Furthermore, a circuit in a broad sense is a circuit realized by combining at least a suitable combination of circuits, circuits, processors, and memory. In other words, it includes application-specific integrated circuits (ASICs), programmable logic devices (for example, simple programmable logic devices (SPLDs), complex programmable logic devices (CPLDs), and field programmable gate arrays (FPGAs)), etc.

[0014] 1.Device configuration Figure 1 is a diagram showing an outline of the configuration of the diffuser 1 according to an embodiment of the present invention. Also, Figure 2 is a diagram showing the configuration of the diffuser 1. As shown in Figure 1, the diffuser 1 includes a control unit 2, a detection unit 3, a diffusion unit 4, and an operation unit 5. This diffuser 1 is a diffuser that diffuses a substance, for example, a fragrance. The control unit 2 controls the entire diffuser 1. Also, as shown in Figure 2, the control unit 2 has a processing unit 21, a storage unit 22, a temporary storage unit 23, a connection unit 24, and a communication unit 25, and these components are electrically connected via a communication bus 26 inside the control unit 2.

[0015] The processing unit 21 is realized by, for example, a Central Processing Unit (CPU), operates according to a predetermined program stored in the storage unit 22, and realizes various functions.

[0016] The storage unit 22 is a non-volatile storage medium that stores various information. This is realized by a storage device such as a Hard Disk Drive (HDD) or a Solid State Drive (SSD).

[0017] The temporary storage unit 23 is a volatile storage medium. This is realized by a memory such as a Random Access Memory (RAM), and stores information (arguments, arrays, etc.) that is temporarily required when the processing unit 21 operates.

[0018] The connection unit 24 is a connection unit conforming to a standard such as a Universal Serial Bus (USB) or a High-Definition Multimedia Interface (HDMI), and enables connection of the detection unit 3, the diffusion unit 4, etc.

[0019] The communication unit 25 is a communication means conforming to, for example, a Local Area Network (LAN) standard, and enables communication between the diffuser 1 and a network such as the local area network or the internet via it.

[0020] The detection unit 3 comprises a quartz crystal oscillator sensor group 31, a gas sensor group 32, and a conversion unit 33.

[0021] The quartz crystal sensor group 31 is composed of multiple quartz crystal sensors, each of which has a quartz crystal formed from a thin film with nonspecific adsorption properties, and each has a different compound deposited on it. Examples of the deposited compounds include D-phenylalanine, D-tyrosine, DL-cestidine, D-glucose, adenine, polyethylene, etc. In all of these cases, the resonant frequency changes due to the adhesion of odor components, and since the degree of odor component adhesion differs depending on the compound, each quartz crystal sensor can detect different odors.

[0022] The gas sensor group 32 consists of multiple gas sensors and is a sensor that detects gases such as carbon dioxide, carbon monoxide, methane, butane, and ammonia. Details of the quartz crystal sensor group 31 and the gas sensor group 32 are described in Patent Document 1, so a detailed explanation is omitted here.

[0023] The conversion unit 33 converts the analog electrical signals output from the crystal oscillator sensor group 31 and the gas sensor group 32 into digital electrical signals.

[0024] Furthermore, since the detection unit 3 uses a group of quartz crystal oscillator sensors 31 and a group of gas sensors 32 to detect odors, the diffuser 1 is provided with an inlet and an outlet (not shown), and is configured so that the detection unit 3 can detect odors from the air around the diffuser 1 through these.

[0025] Alternatively, the detection unit 3 may be equipped with a thermometer, hygrometer, barometer, etc., and the temperature, humidity, atmospheric pressure, etc. obtained from these may be used as the detection result of the detection unit 3, along with the outputs of the quartz crystal oscillator sensor group 31 and the gas sensor group 32.

[0026] The diffusion unit 4 diffuses substances into the air. The substances to be diffused are, for example, fragrances, deodorizers, odor removers, and odor inhibitors, and the diffusion unit 4 diffuses them into the air by spraying them.

[0027] Furthermore, the diffusion unit 4 includes a diffusion material storage unit 41. The diffusion material storage unit 41 stores the material that the diffusion unit 4 diffuses.

[0028] The operation unit 5 comprises a display unit 51 and an input unit 52. The display unit 51 displays the status of the diffuser 1 and is, for example, an indicator light or an LCD monitor. The input unit 52 receives operation input for the diffuser 1 and is, for example, a switch. The display unit 51 and the input unit 52 may be combined to form the operation unit 5 as a touch panel.

[0029] 2. Function of Diffuser 1 Next, we will explain the function of diffuser 1. Figure 3 is a block diagram showing the functional configuration of diffuser 1.

[0030] As shown in the figure, the diffuser 1 comprises a detection unit 3, a detection result acquisition unit 201, an information holding unit 203, a comparison unit 202, a diffusion control unit 205, a diffusion unit 4, an operation unit 5, and an operation control unit 204.

[0031] As shown in Figure 1, the detection unit 3 is configured to detect odors in the air using an odor sensor that includes at least a quartz crystal oscillator sensor.

[0032] The detection result acquisition unit 201 acquires the detection result from the detection unit 3 and outputs the acquired detection result to the information holding unit 203 and the comparison unit 202. However, outputting the detection result to the information holding unit 203 can be omitted.

[0033] The information storage unit 203 stores at least one set of characteristic information indicating the characteristics of the target odor and substance information indicating the substance corresponding to the odor. The characteristic information is a value that the detection unit 3 is expected to output as a detection result when it detects a specific "odor," such as cigarette smoke or pet odor. However, it is not necessary for the substance causing the odor to be identified. The information storage unit 203 stores values ​​that have been previously detected using a device equivalent to that of the detection unit 3 as characteristic information. The substance information is information indicating the substance that diffuses when an odor matching the characteristic information is detected. This substance is a fragrance, deodorant, odor remover, or odor suppressant, and is associated with the characteristic information if it has the effect of eliminating or reducing the odor matching the characteristic information.

[0034] The comparison unit 202 is configured to compare the detection result from the detection unit 3 with the feature information. If the information storage unit 203 stores multiple feature information, the comparison unit 202 compares each feature information. The comparison by the comparison unit 202 outputs whether the detection result matches the feature information, but a match here does not mean a perfect match; a match is defined as the two being similar, including a certain error.

[0035] The diffusion control unit 205 controls the diffusion unit 4 based on the comparison results from the comparison unit 202 or instructions from the operation control unit 204.

[0036] The diffusion unit 4 is configured to diffuse the substance indicated by the substance information corresponding to the characteristic information when the detection result and characteristic information match through comparison by the comparison unit 202. The substance to be diffused is one of those stored in the diffusion substance storage unit 41. The diffusion unit 4 may also be configured to stop the diffusion of the substance indicated by the substance information when the characteristic information corresponding to the substance information no longer matches the detection result while the substance is being diffused.

[0037] The operation unit 5 is for the user of the diffuser 1 to operate manually and is configured to receive instructions to activate the diffusion unit 4 and instructions to specify the substance to be diffused by the diffusion unit 4. In this case, the information holding unit 203 may store the detection result by the detection unit 3 when the operation unit 5 receives an activation instruction as characteristic information, and the substance specified by the specification instruction as substance information, and store the characteristic information and the substance information as a pair. In this case, thereafter, when the detection unit 3 detects a similar odor, the diffusion unit 4 will be activated automatically. Note that the information holding unit 203 may not immediately store the characteristic information and the substance information as a pair when the operation unit 5 receives an operation instruction, but may only store the characteristic information and the substance information as a pair after receiving an operation instruction under the same conditions a predetermined number of times.

[0038] The operation control unit 204 notifies the diffusion control unit 205 of the input from the operation unit 5, and causes the information holding unit 203 to hold the substance specified by the specified instruction.

[0039] Furthermore, although omitted in Figure 3, as shown in Figure 2, the control unit 2 has a communication unit 25. In other words, the diffuser 1 is equipped with a communication unit 25. As shown in Figure 4, this communication unit 25 can communicate with a predetermined information processing device 6 via the network 7 and update the pair of feature information and material information held by the information holding unit 203 according to the instructions of the information processing device 6. Figure 4 is a diagram showing the connection configuration between the diffuser 1 and the information processing device 6.

[0040] 3. Operation of Diffuser 1 Next, we will explain a few examples of the operation flow of Diffuser 1. Figures 5 to 7 are activity diagrams showing the operation flow of Diffuser 1, respectively.

[0041] When the diffuser 1 starts operating, first the detection result acquisition unit 201 acquires the detection result from the detection unit 3 (A101), and the comparison unit 202 compares the acquired detection result with the feature information held in the information holding unit 203 (A102). If the detection result does not match the feature information as a result of the comparison, the same process is repeated.

[0042] On the other hand, if the comparison by the comparison unit 202 results in a detection result that matches the feature information, the diffusion control unit 205 identifies the substance to be diffused based on the substance information stored in the information holding unit 203 in combination with the feature information (A103), and the diffusion unit 4 diffuses the identified substance (A104).

[0043] Furthermore, while the comparison unit 202 is diffusing the substance, the diffuser 1 also has the detection result acquisition unit 201 acquire the detection result from the detection unit 3 (A111), and the comparison unit 202 compares the acquired detection result with the feature information held in the information holding unit 203 (A112). If the comparison result matches the feature information, the same process is repeated.

[0044] On the other hand, if the comparison by the comparison unit 202 does not result in a detection that matches the characteristic information, the diffusion control unit 205 stops the diffusion of the substance (A113).

[0045] Alternatively, the processes from A111 to A113 may be omitted, and the comparison unit 202 may stop the diffusion of the substance after a certain period of time.

[0046] Furthermore, if the diffuser 1 is stopped and a user of the diffuser 1 attempts to start it by operating the control unit 5, the control unit 204 requests the user to specify the substance to be diffused via the control unit 5 (A201).

[0047] When the user specifies the substance to be diffused, the operation control unit 204 generates substance information based on that specification (A202).

[0048] Meanwhile, the detection result acquisition unit 201 acquires detection results from the detection unit 3 (A203) and generates feature information based on the acquired detection results (A204).

[0049] The generated substance information and characteristic information are then combined and stored in the information storage unit 203 (A205). Subsequently, the diffusion unit 4 diffuses the specified substance (A206).

[0050] Furthermore, if activated by user operation, Diffuser 1 will stop diffusing the substance after a certain period of time has elapsed or based on user operation.

[0051] 4. Network-based odor control system 4-1. Example Configuration By the way, the function of diffuser 1 can be distributed, and an odor control system can be configured with multiple diffusers and an information processing device. In this odor control system, the information processing device 6 shown in Figure 4 is replaced with an information processing device 8, and diffuser 1 is replaced with diffuser 9.

[0052] Furthermore, the configuration of the information processing device 8 is as shown in Figure 8, for example. Figure 8 is a diagram showing an example of the configuration of the information processing device 8. As shown in the figure, the information processing device 8 has a processing unit 81, a storage unit 82, a temporary storage unit 83, a connection unit 84, and a communication unit 85, and these components are electrically connected within the information processing device 8 via a communication bus 86.

[0053] The processing unit 81 is implemented, for example, by a central processing unit, and operates according to a predetermined program stored in the storage unit 82, and performs various functions.

[0054] The memory unit 82 is a non-volatile storage medium that stores various types of information. This can be realized by a storage device such as a hard disk drive or a solid-state drive.

[0055] The temporary storage unit 83 is a volatile storage medium. This is implemented by memory such as random access memory, and it stores information (arguments, arrays, etc.) that is temporarily needed when the processing unit 81 is operating.

[0056] The connection section 84 is a connection section that conforms to standards such as the Universal Serial Bus or the High-Definition Multimedia Interface.

[0057] The communication unit 85 is, for example, a communication means conforming to local area network standards, and enables communication between the local area network and networks 7 such as the Internet via the local area network.

[0058] Furthermore, the configuration of diffuser 9 is the same as that of diffuser 1 shown in Figures 1 and 2.

[0059] 4-2. Functions of each part of the odor control system Next, the functions of the information processing device 8 and diffuser 9, which constitute the odor control system, will be described. Figure 9 is a block diagram showing the functional configuration of the information processing device 8 and diffuser 9.

[0060] As shown in the figure, the odor control system comprises an information processing device 8 and a diffuser. This odor control system adjusts the odor of the space.

[0061] The information processing device 8 operates according to a program to realize the various functional units described later. This program is a program that causes the computer to operate or function as the information processing device 8. The information processing device 8 controls the diffuser 9 and includes a reception unit 801, an information holding unit 802, a comparison unit 803, and a providing unit 804.

[0062] The reception unit 801 is configured to receive odor information notified from the diffuser. Odor information will be described later.

[0063] The information storage unit 802 stores at least one set of characteristic information indicating the characteristics of the target odor and substance information indicating the substance corresponding to the odor. The characteristic information and substance information are the same as those stored by the information storage unit 203.

[0064] The comparison unit 803 is configured to compare odor information and feature information. If the information storage unit 802 stores multiple feature information, the comparison unit 803 compares each feature information. The comparison by the comparison unit 803 outputs whether the detection result matches the feature information, but a match here does not mean a perfect match; it means that the two are similar, including a certain error.

[0065] The supply unit 804 is configured to provide the diffuser with the substance indicated by the substance information corresponding to the characteristic information when the odor information and characteristic information match.

[0066] Furthermore, the diffuser 9 diffuses a substance and comprises a detection unit 901, a detection result acquisition unit 902, a notification unit 903, an acquisition unit 904, a diffusion control unit 905, a diffusion unit 906, an operation unit 907, and an operation control unit 908.

[0067] The detection unit 901 is configured to detect odors in the air using an odor sensor that includes at least a quartz crystal oscillator sensor, similar to the detection unit 3.

[0068] The detection result acquisition unit 902 acquires the detection result from the detection unit 901.

[0070] The acquisition unit 904 is configured to acquire material information related to odor information from the information processing device 8.

[0071] The diffusion control unit 905 controls the diffusion unit 906 based on the substance information acquired by the diffusion control unit 905, and also controls the diffusion unit 906 based on instructions from the operation control unit 908.

[0072] The diffusion unit 906 is configured to diffuse the substance indicated by the substance information.

[0074] The operation control unit 908 notifies the diffusion control unit 905 of the input from the operation unit 907, and notifies the detection result acquisition unit 902 of the substance specified by the designation instruction.

[0075] 4-3. Operation of the Odor Control System The odor control system operates similarly to the diffuser 1 described above, except for communication between the information processing device 8 and the diffuser 9. Furthermore, communication between the information processing device 8 and the diffuser 9 is performed using a well-known method. Therefore, the operation of the information processing device 8 and the diffuser 9 can be inferred from the operation of the diffuser 1, and thus a detailed explanation is omitted here.
