Description

Technical Field

[0001] The present invention relates to the field of coordinated control of aromatherapy equipment, and in particular to a coordinated control method and system for multiple aromatherapy equipment in a spatial area. Background Art

[0002] Aromatherapy essential oils can bring a pleasant feeling to users at the right concentration. Aromatherapy concentrations that are too high or too low will reduce the user's pleasure. Aromatherapy equipment is a type of equipment used to assist in the diffusion of aromatherapy essential oils. Common types of aromatherapy equipment include assisted evaporation, two-fluid injection, and volatilization.

[0003] In commercial spaces, aromatherapy equipment is loaded at the entrance of the air supply system. The aromatherapy essential oil discharged from the aromatherapy equipment follows the air flow through the duct system and is discharged from the air outlet to the public space. Due to the large number of air outlets, long air outlet time, and fast air circulation speed in the public space, the aromatherapy essential oil can be evenly distributed in the space at an appropriate concentration.

[0004] Compared with commercial spaces, the application scenarios of aromatherapy equipment in home spaces are more complex. In home environments, users use aromatherapy equipment immediately. On the one hand, the air circulation speed in home environments is slow. On the other hand, due to conditions such as noise restrictions, the selection performance of aromatherapy equipment is affected. The concentration distribution of aromatherapy essential oils discharged by aromatherapy equipment in space will have obvious spatial differences in a short period of time.

[0005] In order to improve user satisfaction with aromatherapy equipment, the current solution on the market is to use multiple aromatherapy equipment. Compared with single aromatherapy equipment, multiple aromatherapy equipment can more quickly distribute aromatherapy essential oils evenly in the home space. But in fact, as the perception receptor of aromatherapy essential oils, in order to more effectively improve the user's experience of aromatherapy equipment, the user's actual experience should be taken as the starting point, and the multiple aromatherapy equipment should be more finely coordinated to control, so as to bring users a better experience of aromatherapy essential oils in a shorter time.

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] An embodiment of the present invention provides a collaborative control method for multiple aromatherapy devices in a spatial area. The execution of the collaborative control method requires relevant pre-preparation.

[0059] The relevant pre-preparations include:

[0060] Create a corresponding virtual space map for the target space area , virtual space map It can be understood as a digitized space area. The space area is transferred to a computer device for simulation. The virtual space map can be obtained by mapping the space area. ;

[0061] In the virtual space map according to actual needs For each position Optimal aromatherapy concentration Calibration, specifically, the ideal aroma concentration required by the user at different locations in the target space may be different, and because the user's state at different locations in the target space is different, the ideal aroma concentration calibrated in this step It can also be understood as compensation for users in different states. For example, in the spatial area, the ideal aromatherapy concentration calibrated at the position above the sofa is lower than the ideal aromatherapy concentration calibrated at the position in the aisle, because the user is walking in the aisle and is stationary on the sofa. When walking, the user's perception of aromatherapy essential oils decreases, and when the user walks, the airflow disturbance is caused, and the aromatherapy concentration inhaled by the user will be relatively reduced. Therefore, the ideal aromatherapy concentration The calibration can be understood as a compensatory measure combining behavior and psychology. Its main purpose is to ensure that users can have a good experience of using aromatherapy essential oils when they are in different spatial positions.

[0062] In actual implementation, since a large amount of exhaustive calculations will be involved later, in order to reduce the hardware requirements of the computing system, the movable space of the space area in the virtual space map is divided into cubes, and each cube With corresponding coordinate values , , For the corresponding virtual space map The total number of cubes in the. Generally, the length, width and height of the cube are generally set to 10 to 15 cm. On the one hand, the dimensions of most aromatherapy devices are within this dimension range. When recording the position of the aromatherapy device, it can be directly determined by the corresponding cube; in addition, since the user's position needs to be located later, considering that the organ that senses aromatherapy essential oils is the nose, the size of 10~15CM is also closer to the size of the human head, and the cube coordinates close to the human head can be used to represent the position of the human head.

[0063] Accordingly, since the selection of aromatherapy equipment will be involved later, when evaluating the effect of aromatherapy equipment, it is necessary to divide the weights according to the essential characteristics of the spatial area; for example, the frequency of activating the aromatherapy equipment required by users in places that can be used for rest, such as chairs and beds, will be higher than in non-staying places such as aisles. Accordingly, the aromatherapy equipment should first better meet the needs of locations with higher frequency of use; converting this logic into mathematical form, that is, locations where aromatherapy equipment is used more frequently should have higher weights when selecting aromatherapy equipment. Therefore, in an optional implementation method, the virtual space map is set according to a preset importance weight rule. Each cube in Importance weight , importance weight value The size of the cube The importance of the embodiment of the present invention can be understood as the frequency of the user needing to start the aromatherapy device when the user is in the corresponding cube position.

[0064] Accordingly, the present invention provides a method for selecting an aromatherapy device for reference.

[0065] Specifically, the aromatherapy equipment manufacturer has an aromatherapy equipment database , the aromatherapy equipment database Records in Aromatherapy equipment, and records of Theoretical working conditions corresponding to the aromatherapy equipment , ; Specifically, Theoretical working conditions of aromatherapy equipment It is essentially a piece of data with four attributes, namely, aromatherapy concentration , adjustable parameter set ,vector , Startup time ; The expression content of this data is Aromatherapy equipment with adjustable parameter set After starting At this moment, the vector distance from the aromatherapy device is Aromatherapy concentration at the location .

[0066] Figure 2 For the aromatherapy device Flowchart of the functional selection steps.

[0067] The aromatherapy device The functional selection steps include:

[0068] S201: Presetting the aromatherapy device The coordinates of the aromatherapy device in the virtual space map ;

[0069] In theory, without setting the aromatherapy device When the coordinates of the aromatherapy device in the virtual space map are calculated, according to the evaluation criteria for the aromatherapy device effect in the embodiment of the present invention, the optimal installation position of the aromatherapy device can be confirmed by exhaustive method; however, it is found in actual service that most users will give other application attributes to the aromatherapy device, such as considering the aromatherapy device as a decoration. Therefore, most users will have clear requirements for the installation position of the aromatherapy device. Therefore, on the one hand, in order to reduce the amount of calculation and reduce the service cost, on the other hand, in order to meet the actual requirements of the user, the aromatherapy device is usually confirmed before selection. installation location.

[0070] S202: The aromatherapy equipment database The The aromatherapy equipment is virtually placed at the corresponding aromatherapy equipment coordinates Department;

[0071] Since it is still in the selection stage, the embodiment of the present invention adopts a simulation method to perform the selection to reduce the actual cost.

[0072] S203: Using the virtual space map Based on the importance weight value Generate the corresponding Aromatherapy equipment Rating map , in Rating map Each cube With corresponding importance weight value property;

[0073] According to the above description, in order to evaluate the application effect of the aromatherapy device in the space area in a targeted manner, it is necessary to assign an importance weight value to each position, that is, each cube, according to the actual situation of the space area.

[0074] S204: Filter out the first Theoretical working conditions of a kind of aromatherapy equipment ;

[0075] Be specific and allow time It is a preset value. In order to achieve better use effect, allow time The smaller the preset value is, the shorter the time it takes for the user to sense the aroma of the essential oil at a suitable concentration after starting the aromatherapy device, and the better the user's experience will be when using the aromatherapy device.

[0076] S205: Calculate the Ratings of aromatherapy equipment ;

[0077] After adding the importance weight value, in the selection process of aromatherapy equipment, in addition to considering the range of the aromatherapy equipment, the coverage of the important areas by the aromatherapy equipment is also considered, which can well take into account both the scope and the effectiveness of the coverage.

[0078] S206: By rating value The highest aromatherapy equipment as aromatherapy equipment use;

[0079] Figure 3 This is a flow chart of a method for calculating a rating value of an aromatherapy device according to an embodiment of the present invention.

[0080] Specifically, in the embodiment of the present invention, the calculation The rating values ​​for aromatherapy equipment include:

[0081] S301: In an exhaustive manner, select from the aromatherapy equipment database Extract the Each set of adjustable parameters in the aromatherapy device , and extracts it into a set of adjustable parameters Then, find each cube Theoretical aroma concentration under a theoretical condition , and Write to the Rating map In the Rating map middle, Recorded as ;

[0082] Specifically, when a specific set of adjustable parameters is extracted When traversing, find the theoretical aroma concentration of each cube under the theoretical working condition of one condition , and the corresponding data Write to Rating map In order to distinguish the data, in the Rating map middle, Recorded as ; After exhaustive enumeration, Rating map Each cube in has the same number of adjustable parameter sets as It should be noted that if When the value is too large, the cube If the location of the aromatherapy device is too far away, Inside, the aromatherapy device is on the cube The influence of this part is too small and was not measured during the working condition measurement process. In order to ensure the regularity of the data set, this part of the cube of Recorded as 0.

[0083] S302: Rating map Based on the scoring formula sum u b = ∑ p = 1 p max [ W p • max ( r b V p ~ e b k b ) ] Calculate the Ratings of aromatherapy equipment .

[0084] In the Rating map In each cube The data recorded in The maximum value of Aromatherapy equipment For this cube The maximum achievable concentration contribution value reflects the aromatherapy device's ability to influence the aromatherapy concentration of the cube. In the actual application of the aromatherapy device, the concentration difference equation can be used to confirm the theoretical working conditions of the aromatherapy device (that is, the parameters in the description function of the theoretical working conditions are all definite values). The aromatherapy device is targeted at a specific cube in actual application. Accordingly, in the selection stage, it is only necessary to consider the aromatherapy device's ability to influence the cube's maximum aromatherapy concentration, so that the selection and application rules are consistent, avoiding wrong selection and omission.

[0085] In addition, for example, when the aromatherapy device is working, the aromatherapy concentration at the outlet of the essential oil is far higher than the general value, but the human body is generally not close to the outlet of the essential oil of the aromatherapy device. Therefore, when the aromatherapy device is working, some areas near the aromatherapy device are actually unconventional application areas. In the unconventional application area, the excessively high aromatherapy concentration value may interfere with its final score. Therefore, in an optional implementation method, when the cube Theoretical aroma concentration under a theoretical condition Greater than the preset essential oil concentration threshold When The corresponding theoretical aromatherapy concentration is recorded as the preset essential oil concentration threshold And write to Rating map In the process, the excessive essential oil concentration is unified to the preset essential oil concentration threshold. , to avoid excessively high scores in unconventional areas, which may interfere with and affect the selection of aromatherapy equipment.

[0086] Similarly, since too high a concentration of aromatherapy will seriously affect the user's experience, in actual applications, it is necessary to avoid too high a concentration of aromatherapy at possible locations. In an optional implementation, in the virtual space map For each cube Maximum allowable concentration of essential oils for aromatherapy Calibration of

[0087] In Filter out the first Theoretical working conditions of a kind of aromatherapy equipment After that, For the secondary condition, a theoretical working condition of the primary condition that satisfies the secondary condition is selected, and the theoretical working condition of the primary condition that satisfies the secondary condition is calculated. Ratings of aromatherapy equipment .

[0088] Furthermore, in the selection of aromatherapy equipment, in addition to functional factors, non-functional factors need to be considered in many cases, such as the price of the aromatherapy equipment, the shape of the aromatherapy equipment, the working noise of the aromatherapy equipment, etc. Therefore, in an optional implementation method, in the aromatherapy equipment database It also records Several non-functional attributes of aromatherapy equipment;

[0089] The collaborative control method also includes an aromatherapy device Non-functional selection steps;

[0090] The aromatherapy device The non-functional selection steps include:

[0091] In the aromatherapy device Before the functional selection step, the aromatherapy device database is selected according to the non-functional attribute conditions related to the non-functional attributes. In The aromatherapy equipment database is screened Aromatherapy equipment that does not meet the non-functional attribute conditions will be temporarily eliminated;

[0092] In the aromatherapy device In the functional selection step, the aromatherapy equipment database Aromatherapy equipment that has been temporarily removed cannot be selected.

[0093] In the virtual space map Middle Pair Aromatherapy equipment , Marking the location of the aromatherapy device There are corresponding aromatherapy equipment coordinates in the virtual space map , ;

[0094] Each aromatherapy device have Tunable parameters , Aromatherapy equipment No. adjustable parameters, , , corresponding to the aromatherapy device , each of the adjustable parameters has a corresponding value range, and the The maximum number of combinations of adjustable parameters under different values ​​is The set of adjustable parameters, The symbol for a set of adjustable parameters is , , , the aromatherapy device Theoretical working conditions Described as , Indicates the aromatherapy device In the The set of adjustable parameters works under the aromatherapy device start up After a period of time, the aromatherapy device The vector distance is The theoretical aromatherapy concentration at the location of the aromatherapy device Theoretical working conditions is known data; specifically, each aromatherapy device will have some corresponding substantial use parameters during operation. Compared with other non-substantial use parameters, the change of substantial use parameters can affect the effect of the aromatherapy device on the aromatherapy concentration of the external environment. Therefore, the adjustable parameters referred to in the embodiment of the present invention are substantial use parameters. Basically, the adjustable parameters need to be selected according to the specific design of the aromatherapy device. For example, the aromatherapy device in the form of evaporation (generally using an ultrasonic generator as an evaporator) has adjustable parameters including evaporator power, and the aromatherapy device in the form of two-fluid has adjustable parameters including injection pressure, etc.; in addition, in addition to the generator itself, some aromatherapy devices are also provided with external structures similar to swing leaf structures. These external structures are used to affect the effect of the aromatherapy device on the external environment and the aromatherapy concentration. Therefore, the relevant adjustment parameters of the external structure are also adjustable parameters. For the sake of convenience, a combination of a group of adjustable parameters is named as an adjustable parameter set. Under ideal conditions, when the aromatherapy device works under a fixed adjustable parameter set, the working effect of the aromatherapy device remains unchanged. Based on this definition, actual testing can be carried out in the laboratory to determine in advance the working conditions of the aromatherapy equipment under each adjustable parameter set.

[0095] Specifically, according to the application characteristics of the embodiment of the present invention, each aromatherapy device Theoretical working conditions Described as ; Theoretical working conditions It contains four data, namely , , , ; Aromatherapy equipment The working status (the working status corresponding to the selected adjustable parameter set), Indicates the aromatherapy device The vector distance of Indicates the start time of the aromatherapy device. Indicates the aromatherapy device In the The set of adjustable parameters works under the aromatherapy device start up After a period of time, the aromatherapy device The vector distance is Theoretical aromatherapy concentration at the location; each aromatherapy device The theoretical working condition is actually the aromatherapy equipment Description of the current working status and aromatherapy equipment Effect on the surrounding environment. In actual application, the theoretical working conditions can be adjusted according to data application requirements. For example, in an embodiment of the present invention, the aromatherapy device Theoretical working conditions Described as , mainly used to emphasize the change of the aromatherapy concentration around the aromatherapy device with the other three parameters; in essence, the four data are groups of interrelated variables. When three of them are determined, the other variable is also confirmed accordingly; when two of them are determined, there is a fixed corresponding relationship between the other two variables. For example, when confirming the aromatherapy device Working status and start-up time of aromatherapy equipment After that, each vector distance is The corresponding theoretical aromatherapy concentration value is located at each position; when the aromatherapy device is confirmed The working state and vector distance are When the position is The theoretical aromatherapy concentration value at the position varies with the start-up time of the aromatherapy device Specifically, each type of aromatherapy equipment can be tested in the laboratory under theoretical working conditions.

[0096] The main technical problem that needs to be solved in the determination of theoretical working conditions is how to measure the concentration of aromatherapy essential oils in the space in real time. After a posteriori test of the test data, in order to achieve a more efficient theoretical working condition determination, the embodiment of the present invention provides a feasible theoretical working condition determination method for implementation.

[0097] The core idea of ​​this theoretical working condition measurement method is that for most aromatherapy equipment, its working logic is consistent with that of the atomizer. A large number of aromatherapy essential oil droplets are brought out through the fluid, and the aromatherapy macromolecules in the aromatherapy essential oil droplets then move and dissipate from the aromatherapy essential oil droplets through the form of molecular motion; therefore, the measurement of the theoretical working condition of the aromatherapy equipment can actually be divided into two parts. One part is to measure the change of the spatial distribution of the aromatherapy essential oil droplets over time, and the other part is to measure the dissipation of the aromatherapy macromolecules based on the spatial distribution of the aromatherapy essential oil droplets.

[0098] The method for determining the theoretical working condition of the aromatherapy device according to the embodiment of the present invention includes:

[0099] S401: placing the aromatherapy device to be tested at a fixed position;

[0100] Reference Figure 4 Schematic diagram of the working condition measurement structure of the aromatherapy device according to an embodiment of the present invention. Before the working condition measurement begins, the aromatherapy device to be measured is placed in a fixed position and the stability of the coordinate system is maintained.

[0101] S402: starting the aromatherapy device to be tested with the adjustable parameter set to be tested;

[0102] S403: observing the state of the fluid emitted by the aromatherapy device to be tested, and synchronously measuring the aromatherapy concentration inside the fluid and the aromatherapy concentration outside the fluid;

[0103] Figure 5 This is a schematic diagram of the aromatherapy impact range of the aromatherapy equipment during the test process.

[0104] Specifically, the aromatherapy essential oil can be observed externally in the droplet state by dyeing. Generally, by using a high-definition camera and combining image post-processing, the distribution of the aromatherapy essential oil in the droplet state in space when the atomization device is working can be well obtained. In practical applications, the observed graphical data can be expressed in a parameterized form in combination with relevant knowledge such as jet simulation and atomizer model theory, which can greatly reduce the complexity of operation for repetitive theoretical working condition measurement work. As shown in the figure, the grid line area can be regarded as the area where the aromatherapy essential oil can be observed in the droplet state (the adjustable parameter set is fixed, and the observation time is set at a larger value). The aromatherapy essential oil in this area is mainly in the droplet state. Relatively speaking, the aromatherapy concentration in this area is high, and the aromatherapy concentration in this area can be regarded as a fixed value. After obtaining the area of ​​the aromatherapy essential oil in the droplet state, the dissipation area of ​​the aromatherapy macromolecule can be roughly delineated, such as the shaded area shown in the figure. Accordingly, the detection equipment can be used to measure the concentration of the relevant area in a targeted manner. Based on implementation cost considerations, generally, several detection probes are set in the relevant area, as shown by the crosshairs in the figure. For the concentration of aromatherapy macromolecules, the electrochemical sensor method or the pH test method can be used; the electrochemical sensor method is understood as the carboxyl or amino group in the aromatherapy macromolecule affects the electrical conduction in the sensor, and the concentration of the aromatherapy essential oil is inferred by judging the degree of influence. The pH test method uses the color reaction between the acidity and alkalinity of the aromatherapy macromolecule and the indicator to reflect the concentration of the aromatherapy essential oil through the color change.

[0105] It should be noted that, during the working condition test, the space where the aromatherapy device to be tested is located is a relatively open space. When the aromatherapy device to be tested continues to work, the escaped aromatherapy macromolecules will not accumulate. In actual applications, due to the relative sealing of the space, when the aromatherapy device continues to work for a period of time, the accumulation of aromatherapy macromolecules in the space increases the aromatherapy concentration in the air. There may be a situation where the accumulated aromatherapy concentration is higher than the theoretical influence of the aromatherapy device on the surrounding environment. Therefore, the collaborative control method of multiple aromatherapy devices in the embodiment of the present invention is mainly aimed at the short-term collaborative control after the aromatherapy device is started, and the subsequent collaborative control application can be implemented according to the existing technology.

[0106] Figure 1 This is a flow chart of a collaborative control method for multiple aromatherapy devices according to an embodiment of the present invention.

[0107] After the aforementioned preparatory steps, the method for collaboratively controlling multiple aromatherapy devices in a spatial area provided by an embodiment of the present invention includes:

[0108] S101: receiving an aromatherapy device start signal given by a target user;

[0109] When the user needs the aromatherapy device to work, the user will send a start signal to the aromatherapy device through related equipment or programs. Generally, in addition to conventional physical switches, in the current smart home environment, the aromatherapy device is generally connected to the central control host, and the central control host receives and forwards the aromatherapy device start signal given by the target user to the aromatherapy device.

[0110] S102: Marking representative spatial coordinates for indicating the spatial position of the target user in the virtual spatial map , and obtain the representative space coordinates Ideal aroma concentration ;

[0111] The location confirmation method of the target user in the spatial area can be obtained through additional monitoring equipment, or can be reflected by the device (usually a mobile phone) that sends the aromatherapy device activation signal. The location of the target user in the spatial area corresponds to a representative spatial coordinate in the virtual space map. Specifically, since the organ that perceives aromatherapy essential oils is the nose, the position of the target user's nose is generally used as the identification feature of the target user. Accordingly, the representative space coordinates are generally the position of the target user's nose. Accordingly, after obtaining the representative space coordinates of the target user, the representative space coordinates can be used to identify the target user. Get the corresponding ideal aromatherapy concentration .

[0112] S103: Based on the allowed time and the ideal aromatherapy concentration For each of the aromatherapy devices Choose the right set of tunable parameters , so that the concentration difference equation | [ ∑ u = 1 M r u ( u k u = k u best , A 0 − A u , t 0 ) ] − r ' A 0 | = minutes { | [ ∑ u = 1 M r u ( u k u = k u ' , A 0 − A u , t 0 ) ] − r ' A 0 | } Established, ;

[0113] Specifically, the concentration difference equation is interpreted (calculated) as follows: After taking the value, select a set of adjustable parameters , calculate the aromatherapy equipment under this condition The theoretical aroma concentration at the representative space coordinates, and then continue to The value is obtained until the value is completed, thereby obtaining a set of adjustable parameters. With Aromatherapy equipment pairs represent spatial coordinates The combined effect of the aromatherapy concentration (i.e. the total aromatherapy concentration corresponding to the spatial coordinate) is calculated by comparing it with the ideal aromatherapy concentration. The error value is calculated by the difference method. When the error value is the smallest, it indicates that the set of adjustable parameters is The combination has the best effect, and this set of adjustable parameter combinations should be used in practical applications.

[0114] It should be noted that, in the embodiment of the present invention, in a short period of time, the aroma concentration at each position in the spatial area can be understood as the superposition of the effects of various aromatherapy devices on the position.

[0115] S104: Using the adjustable parameter set Set up the corresponding aromatherapy equipment And start synchronously Aromatherapy equipment .

[0116] In step S103, The best working conditions for aromatherapy equipment are set according to the adjustable parameter set with the best matching effect. Set adjustable parameters for each aromatherapy device and start them simultaneously Aromatherapy equipment can be used to achieve At the time, the aroma concentration at the representative space coordinates where the user is located is closest to the optimal value (that is, the ideal aroma concentration defined in the embodiment of the present invention). ).

[0117] Further, according to the above description, since the space area is a relatively closed space, when the aromatherapy device continues to work for a period of time, the aromatherapy accumulation concentration in the space area is relatively high.
