Description

Technical Field

[0001] The present invention relates to the technical field of indoor air conditioning, and in particular to a visual gas composition display system and method. Background Art

[0002] Aromatherapy machines generally use ultrasonic atomization to convert the essential oil in the container into fine fragrant smoke and release it into the air. Placing an aromatherapy machine indoors can improve the indoor air, including eliminating odors, increasing indoor air humidity, etc., and at the same time can release fragrant odors to make the indoor environment more comfortable and pleasant. However, the existing aromatherapy machines have a single flavor and poor personalized experience. Long-term use will cause users to develop olfactory adaptability, that is, if they are in the same fragrance environment for a long time, the user's sense of smell will gradually adapt and weaken the ability to perceive the fragrance, thereby reducing the perception of the fragrance. In addition, due to the diversity of the indoor environment and its dynamic changes, the flow state of indoor air is complex and changeable. Some areas may have poor air flow for a long time. Long-term use of aromatherapy machines may cause excessive fragrance concentration in these areas, which will have adverse effects on the human body. Other areas may have good air flow, so that the fragrance released by the aromatherapy machine is quickly diluted or taken away, resulting in poor aromatherapy effect. Since air and fragrance are invisible and colorless, it is difficult for users to have a more intuitive perception of the aromatherapy effect. Therefore, it is impossible to effectively adjust the placement, smell and concentration of the aromatherapy machine, resulting in a poor user experience of the aromatherapy machine.

[0071] A visual gas composition display system and method provided according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0073] In the technical solutions of some embodiments of the present invention, the gas release device includes a containing chamber for containing an aromatherapy liquid of a certain flavor, an atomizer for atomizing the aromatherapy liquid in the containing chamber, and a first IoT (Internet of Things) module for communicating with the mobile communication terminal. In the technical solution of this embodiment, each gas release device can only release aromatherapy gas of a certain flavor, and the visual gas composition display system includes a plurality of gas release devices placed at different positions or adjacent positions indoors for releasing aromatherapy gases of different flavors, and the mobile communication terminal is connected to the gas release device to control the gas release device to release aromatherapy gas of the corresponding flavor. The atomizer is used to atomize the aromatherapy liquid in the aromatherapy liquid containing chamber to form aromatherapy gas and release it into the air. In a specific implementation, the atomizer can be any one of an ultrasonic atomizer, a thermal atomizer, a compressed air atomizer or a sprayer.

[0074] In the technical solutions of some embodiments of the present invention, the gas release device includes a receiving chamber for receiving aromatherapy liquids of multiple flavors, an atomizer for atomizing the aromatherapy liquid in the receiving chamber, and a first IoT module for communicating with the mobile communication terminal. The receiving chamber includes a plurality of sub-receiving chambers, each of which contains an aromatherapy liquid of a different flavor. Aromatherapy gases of different flavors can be released by delivering the aromatherapy liquids in different sub-receiving chambers to the atomizer for atomization. In the technical solution of this embodiment, only one gas release device is required to release aromatherapy gases of different flavors under the control of the mobile communication terminal.

[0075] The olfactory sensor is a sensor device that uses the principle of chemical perception to simulate the human olfactory system by converting the physical or chemical changes produced by the adsorption and desorption process of gas molecules by sensitive materials into measurable electrical signals or optical signals. The olfactory sensor can be any one of a metal oxide sensor, a polymer composite material sensor, a biosensor or a nano gas-sensitive sensor.

[0076] Preferably, the wind speed and direction sensor is an ultrasonic wind speed and direction sensor. Since the propagation speed of sound in the air will be superimposed on the airflow speed in the wind direction, when the propagation direction of the ultrasonic wave is the same as the wind direction, its speed will increase; conversely, if the propagation direction of the ultrasonic wave is opposite to the wind direction, its speed will slow down. Therefore, by calculating the change in the speed of the ultrasonic wave propagating in the air, the accurate wind speed and wind direction can be obtained.

[0077] The mobile communication terminal can be a mobile communication device such as a mobile phone, a tablet computer or a laptop computer. The gas sensing device includes a second IoT module for communicating with the mobile communication terminal. In the technical solutions of some embodiments of the present invention, the first IoT module and the second IoT module are short-range communication modules, such as a Bluetooth communication module, a Zigbee communication module or a Wi-Fi communication module, and the mobile communication terminal directly establishes a communication connection with the gas release device and the gas sensing device through short-range communication technology. In the technical solutions of other embodiments of the present invention, the visual gas composition display system also includes a cloud server, the first IoT module and the second IoT module are cellular communication modules, the gas release device, the gas sensing device, and the mobile communication terminal establish a communication connection with the cloud server through a cellular communication network. In the technical solution of this embodiment, the cloud server provides background services for the gas release device, the gas sensing device and the mobile communication terminal, including data transfer services and remote control services.

[0078] like Figure 2 As shown, the mobile communication terminal is specifically configured as follows:

[0079] receiving an aroma gas release request input by a user through a mobile communication terminal, wherein the aroma gas release request includes a release area identifier and an aroma gas type;

[0080] Determine the corresponding target gas release device and target gas sensor device according to the release area identifier;

[0081] Controlling the target gas release device to release aroma gas corresponding to the aroma gas type;

[0082] Acquire gas sensing data from the target gas sensing device, wherein the gas sensing data includes concentration data of the aromatherapy gas and air flow data at the location of the target gas sensing device;

[0083] Calculating dynamic distribution data of indoor aromatherapy gas based on the gas sensing data, wherein the dynamic distribution data includes concentration distribution data of the aromatherapy gas in the release area;

[0084] Dynamic distribution data of indoor aromatherapy gas is dynamically displayed on the screen of the mobile communication terminal.

[0085] In the technical solution of the present invention, the indoor space is divided into several release areas according to the arrangement of the gas release device and the gas sensor device, each release area has a unique release area identifier as its identity identification identifier, and the gas release device and the gas sensor device are associated with the release area identifier of the corresponding release area according to their arrangement positions. That is, after determining the release area identifier included in the aromatherapy gas release request, the target gas release device and the target gas sensor device associated with the release area identifier can be determined from the database.

[0086] Preferably, each release area is arranged with at least one gas release device and several gas sensor devices, and the multiple gas sensor devices in the same release area have different relative positions and relative distances with respect to the gas release devices in the release area, so that the gas sensor data corresponding to the aromatherapy gas released by the gas release device can be accurately obtained under different air flow conditions.

[0087] Furthermore, the user sends a fragrance gas release request to the gas release device through the application on the mobile communication terminal. Exemplarily, the mobile phone application is configured with a number of UI (User Interface) interactive elements corresponding to different types of fragrance gases. These UI interactive elements can be text icons or picture logos, etc. For example, an apple picture is used as a picture logo corresponding to apple-flavored fragrance. When the user selects the picture logo in a specific release area, the gas release device in the corresponding release area is controlled to release apple-flavored fragrance gas.

[0088] Furthermore, the mobile communication terminal periodically acquires gas sensor data from the target gas sensor device to update the dynamic display interface of the indoor aroma gas component distribution. Since the aroma gas diffuses quickly in the air, in order to ensure the accuracy of the indoor aroma gas component distribution data in the dynamic display interface, the period for the mobile communication terminal to acquire gas sensor data from the target gas sensor device should be configured to be a relatively short duration. The step of dynamically displaying the dynamic distribution of indoor aroma gas on the screen of the mobile communication terminal specifically includes distinguishing different types of aroma gas and distinguishing different concentrations of the aroma gas in different display modes. For example, in the dynamic display interface, different types of aroma gas are distinguished by different picture labels, and different concentrations of aroma gas are distinguished by different colors.

[0089] Further, the air flow data includes wind speed data and wind direction data at the location of the target gas sensor device. In the step of acquiring gas sensor data from the target gas sensor device, the mobile communication terminal is specifically configured as follows:

[0090] The coordinates of the location of the target gas sensor device are determined as the monitoring point coordinates , 1 to A positive integer between is the number of monitoring points in the release area, For the The coordinates of the monitoring points at each monitoring point;

[0091] Determining the target aromatherapy gas released by the target gas releasing device;

[0092] Periodically collect the concentration of the target aromatherapy gas at the coordinates of the monitoring point , wind speed Wind direction ,in is the gas number of the target aromatherapy gas, is the acquisition time of the gas sensing data, For the The monitoring points are located in The azimuth of the wind direction at the moment, For the The monitoring points are located in The altitude angle of the wind direction at the moment.

[0093] Furthermore, a gas sensor device is also arranged at the location of the gas release device, for obtaining aromatherapy gas concentration data and air flow data at the location of the gas release device. It indicates the number of monitoring points in the release area, and can also indicate the number of gas release devices in the release area.

[0094] In the technical solution of the present invention, a unique identification number is assigned to each aromatherapy gas as its gas number. The gas number of the target aroma gas is transmitted to the olfactory sensor in the target gas sensing device, so that the olfactory sensor monitors the concentration of the target aroma gas at the coordinates of the monitoring point.

[0095] In the technical solution of the above-mentioned implementation mode, Indicates that the target aroma gas is in the The monitoring points are located in Gas concentration at a given moment. Indicates The monitoring points are located in The wind speed at the moment. For the The coordinates of the monitoring points in the global coordinate system of the release area.

[0096] Furthermore, in the step of calculating the dynamic distribution data of the indoor aromatherapy gas based on the gas sensor data, the mobile communication terminal is specifically configured as follows:

[0097] Obtain the monitoring point coordinates of the target gas sensor device ;

[0098] According to the monitoring point coordinates of the target gas sensor device The release area is divided into sub-areas, each sub-area corresponds to a gas sensing device;

[0099] According to the target aromatherapy gas The monitoring points are located in Gas concentration at the time Calculate the target aroma gas in the The equivalent source strength at each monitoring point ;

[0100] Calculate the The coordinates of each sub-area are Correction parameters for the position ;

[0101] The gas sensing data of the target gas sensing device is input into the Gaussian plume equation to calculate the concentration distribution in the corresponding sub-area:

[0102] ,

[0103] in For the The three-dimensional coordinates of any point in the sub-region, is the horizontal diffusion parameter, is the vertical diffusion parameter.

[0104] Further, according to the target aromatherapy gas in the The monitoring points are located in Gas concentration at the time Calculate the target aroma gas in the The equivalent source strength at each monitoring point In the step, the mobile communication terminal is specifically configured as follows:

[0105] Obtain the target aromatherapy gas in the first The monitoring points are located in Gas concentration at the time and flow rate ;

[0106] Calculate the target aroma gas in the The equivalent source strength at each monitoring point is:

[0107] .

[0108] Specifically, the target aromatherapy gas is The monitoring points are located in The flow rate at the time is In the target gas sensing device The wind speed and direction sensor at the time measured the wind speed . Assume that There is a unit area of ​​1 square meter at each monitoring point perpendicular to the air flow direction. The gas moves at a speed of When meters per second pass through the unit area, the volume of gas passing through the unit area per second is cubic meters, so that the target aroma gas can be calculated in the first The equivalent source strength at each monitoring point is:

[0109] .

[0110] Furthermore, in calculating The coordinates of the sub-regions are Correction parameters for the position In the step, the mobile communication terminal is specifically configured as follows:

[0111] Get the The coordinates of the monitoring points in each sub-area ;

[0112] Determine Concentration correction factor for each sub-area ;

[0113] Based on the monitoring point coordinates and the coordinates of the target location Calculate the correction parameters for the target position:

[0114] .

[0115] Specifically, the target position is the calculated correction parameter The corresponding The coordinate position of the three-dimensional relative coordinate system in the sub-region The concentration correction factor It is related to the model parameters of the olfactory sensor itself, the concentration of the aroma gas in the current sub-area of ​​the release area and the wind speed, and also to the target position and the The target position is related to the distance between the monitoring points of the sub-areas. The farther the distance between the monitoring points in a sub-area is, the greater the error in the concentration calculation will be if no correction is performed.

[0116] Furthermore, in determining Concentration correction factor for each sub-area In the step, the mobile communication terminal is specifically configured as follows:

[0117] Get at least one The coordinates of the monitoring points in the adjacent sub-regions of the sub-regions and the concentration of the target aromatherapy gas at the monitoring point of the adjacent sub-area ;

[0118] The coordinates of the adjacent sub-area in the global coordinate system of the release area are Convert to The coordinates of the sub-regions in the three-dimensional relative coordinate system:

[0119] ,

[0120] in To convert the coordinates of the global coordinate system of the release area into the The coordinate transformation matrix of the three-dimensional coordinates of the sub-regions relative to the coordinate system;

[0121] According to the monitoring points of the adjacent sub-areas Gas concentration at the time Calculate the Concentration correction factor for each sub-area

[0122] .

[0123] Specifically, The sub-region adjacent to the first sub-region refers to the sub-region adjacent to the first sub-region in the release region. It should be noted that since the three-dimensional relative coordinate system of each sub-area is a dynamic coordinate system, the direction of its coordinate axis changes with the wind direction, so the coordinates of the global coordinate system of the release area are converted to the first The coordinate transformation matrix of the three-dimensional coordinate system of the sub-regions It also changes dynamically, that is, the coordinate transformation matrix Over time More specifically, the coordinate transformation matrix Follow The monitoring points are located in The azimuth of the wind direction at the moment and The monitoring points are located in The altitude angle of the wind direction at the moment changes due to changes in the.

[0124] Further, according to the monitoring point coordinates of the target gas sensor device, The release area is divided into In the step of generating a sub-area, the mobile communication terminal is specifically configured as follows:

[0125] According to wind speed Wind direction Calculate the The coverage parameters of the monitoring points include the upwind diffusion distance and vertical diffusion distance , where the upwind diffusion distance The vertices of the covered surface and The distance between the monitoring points, the vertical diffusion distance The covered surface and the The intersection of the straight lines of the monitoring points is relative to the The distance between the monitoring points;

[0126] Construct the first A coverage surface of monitoring points, wherein the coverage surface is an elliptical parabola;

[0127] The release area is divided into sub-areas.

[0128] In the technical solution of the above embodiment, the upwind diffusion distance is the vertex of the elliptical parabola and the The distance between the monitoring points, the diffusion curvature is the curvature at the vertex of the elliptical parabola. The elliptical parabola is an infinitely extended surface starting from its vertex. The release area is divided into In the step of dividing the released area into sub-areas, the elliptical parabola intersects with the boundary of the released area to divide the released area into sub-areas. In the specific implementation process, The corresponding monitoring points The cover surface will actually divide the release area into sub-regions, but there is a sub-region that does not contain any monitoring point. In the step of inputting the gas sensing data of the target gas sensing device into the Gaussian plume equation to calculate the concentration distribution in the corresponding sub-region, the sub-region that does not contain any monitoring point can be merged into the adjacent region for calculation, or the sub-region can be directly ignored.

[0129] Furthermore, according to The monitoring points are located in Wind speed at the moment Wind direction Calculate the In the step of monitoring coverage parameters of a monitoring point, the mobile communication terminal is specifically configured as follows:

[0130] Get ambient air density and The monitoring points are located in Wind speed at the moment and the concentration of the target aroma gas ;

[0131] Calculate the The monitoring points are located in Upwind diffusion distance at the moment:

[0132] ,

[0133] Calculate the The monitoring points are located in Vertical diffusion distance at the moment:

[0134] ,

[0135] in and It is an empirical coefficient measured in a laboratory environment.

[0136] Further, in constructing the first In the step of covering the surface of the monitoring points, the mobile communication terminal is specifically configured as follows:

[0137] According to the upwind diffusion distance and the vertical diffusion distance Calculate the length of the major semi-axis of the covered surface:

[0138] ;

[0139] According to the upwind diffusion distance and the vertical diffusion distance Calculate the length of the minor semiaxis of the covered surface:

[0140] ;

[0141] Construct the surface equation of the covering surface:

[0142] .

[0143] Further, in constructing the first After the step of covering the surface of the monitoring points, the mobile communication terminal is specifically configured as follows:

[0144] Determine the intersection area of ​​the space covered by the coverage surfaces of multiple monitoring points;

[0145] Calculate the distance between each position in the intersection area and the corresponding monitoring point;

[0146] The positions in the intersection area are allocated to the sub-areas corresponding to the monitoring points according to the distances between the positions in the intersection area and the corresponding monitoring points.

[0147] Specifically, the coverage surface of any monitoring point will definitely intersect with the coverage surface of the adjacent monitoring point during the extension process, thereby generating the intersection area. Since the wind directions of the various monitoring points are often not completely consistent and change over time, the intersection position of the coverage surface with the coverage surface of the adjacent monitoring point is not a fixed position, resulting in different distances between the intersection area and each monitoring point. Therefore, a solution can be adopted to allocate the entire intersection area to the sub-area corresponding to the monitoring point closest to the intersection area. Or in other embodiments, the intersection area can be further divided, that is, the intersection area can be further subdivided according to the distance between each position in the intersection area and each monitoring point, and the subdivided area after the intersection area is divided is merged into the sub-area corresponding to the monitoring point closest to the intersection area.

[0155] In the technical solution of the present invention, the indoor space is divided into several release areas according to the arrangement of the gas release device and the gas sensor device, each release area has a unique release area identifier as its identity identification identifier, and the gas release device and the gas sensor device are associated with the release area identifier of the corresponding release area according to their arrangement positions. That is, after determining the release area identifier included in the aromatherapy gas release request, the target gas release device and the target gas sensor device associated with the release area identifier can be determined from the database.

[0156] Preferably, each release area is arranged with at least one gas release device and several gas sensor devices, and the multiple gas sensor devices in the same release area have different relative positions and relative distances with respect to the gas release devices in the release area, so that the gas sensor data corresponding to the aromatherapy gas released by the gas release device can be accurately obtained under different air flow conditions.

[0157] Furthermore, the user sends a fragrance gas release request to the gas release device through the application on the mobile communication terminal. Exemplarily, the mobile phone application is configured with a number of UI (User Interface) interactive elements corresponding to different types of fragrance gases. These UI interactive elements can be text icons or picture logos, etc. For example, an apple picture is used as a picture logo corresponding to apple-flavored fragrance. When the user selects the picture logo in a specific release area, the gas release device in the corresponding release area is controlled to release apple-flavored fragrance gas.

[0158] Furthermore, the mobile communication terminal periodically acquires gas sensor data from the target gas sensor device to update the dynamic display interface of the indoor aroma gas component distribution. Since the aroma gas diffuses quickly in the air, in order to ensure the accuracy of the indoor aroma gas component distribution data in the dynamic display interface, the period for the mobile communication terminal to acquire gas sensor data from the target gas sensor device should be configured to be a relatively short duration. The step of dynamically displaying the dynamic distribution of indoor aroma gas on the screen of the mobile communication terminal specifically includes distinguishing different types of aroma gas and distinguishing different concentrations of the aroma gas in different display modes. For example, in the dynamic display interface, different types of aroma gas are distinguished by different picture labels, and different concentrations of aroma gas are distinguished by different colors.

It indicates the number of monitoring points in the release area, and can also indicate the number of gas release devices in the release area.

[0164] In the technical solution of the present invention, a unique identification number is assigned to each aromatherapy gas as its gas number. The gas number of the target aroma gas is transmitted to the olfactory sensor in the target gas sensing device, so that the olfactory sensor monitors the concentration of the target aroma gas at the coordinates of the monitoring point.

Indicates The monitoring points are located in The wind speed at the moment. For the The coordinates of the monitoring points in the global coordinate system of the release area.

[0166] Furthermore, the step of calculating the dynamic distribution data of the indoor aromatherapy gas based on the gas sensor data specifically includes:

[0167] Obtain the monitoring point coordinates of the target gas sensor device ;

[0168] According to the monitoring point coordinates of the target gas sensor device The release area is divided into sub-areas, each sub-area corresponds to a gas sensing device;

[0169] According to the target aromatherapy gas The monitoring points are located in Gas concentration at the time Calculate the target aroma gas in the The equivalent source strength at each monitoring point ;

[0170] Calculate the The coordinates of each sub-area are The correction parameters of the position ;

[0171] The gas sensing data of the target gas sensing device is input into the Gaussian plume equation to calculate the concentration distribution in the corresponding sub-area:

[0172] ,

[0173] in For the The three-dimensional coordinates of any point in the sub-region, is the horizontal diffusion parameter, is the vertical diffusion parameter.

[0174] Furthermore, For the The coordinate value in the three-dimensional relative coordinate system in the sub-region is a dynamic coordinate system, that is, the conversion matrix between the three-dimensional relative coordinate system and the global coordinate system of the release region changes over time. More specifically, The three-dimensional relative coordinate system in the sub-area is based on the The monitoring point is taken as the origin, Gas sensing devices in The wind direction detected at any moment is Axis direction.

[0175] The horizontal diffusion parameter is the diffusion parameter of the target aromatherapy gas in the horizontal direction, where the horizontal direction is parallel to the ground, or perpendicular to the gravity direction. is the diffusion parameter of the target aromatherapy gas in the direction parallel to gravity, and the horizontal diffusion parameter and the vertical diffusion parameter It is an empirical value obtained by statistical analysis of a large amount of experimental data measured in an indoor environment.

[0194] .

[0195] Specifically, The sub-region adjacent to the first sub-region refers to the sub-region adjacent to the first sub-region in the release region. It should be noted that since the three-dimensional relative coordinate system of each sub-area is a dynamic coordinate system, the direction of its coordinate axis changes with the wind direction, so the coordinates of the global coordinate system of the release area are converted to the first The coordinate transformation matrix of the three-dimensional coordinate system of the sub-regions It also changes dynamically, that is, the coordinate transformation matrix Over time More specifically, the coordinate transformation matrix Follow The monitoring points are located in The azimuth of the wind direction at the moment and The monitoring points are located in The altitude angle of the wind direction at the moment changes due to changes in the.

[0196] Further, according to the monitoring point coordinates of the target gas sensor device The release area is divided into The steps for each sub-area include:

[0218] The positions in the intersection area are allocated to the sub-areas corresponding to the monitoring points according to the distances between the positions in the intersection area and the corresponding monitoring points.

[0219] Specifically, the coverage surface of any monitoring point will definitely intersect with the coverage surface of the adjacent monitoring point during the extension process, thereby generating the intersection area. Since the wind directions of the various monitoring points are often not completely consistent and change over time, the intersection position of the coverage surface with the coverage surface of the adjacent monitoring point is not a fixed position, resulting in different distances between the intersection area and each monitoring point. Therefore, a solution can be adopted to allocate the entire intersection area to the sub-area corresponding to the monitoring point closest to the intersection area. Or in other embodiments, the intersection area can be further divided, that is, the intersection area can be further subdivided according to the distance between each position in the intersection area and each monitoring point, and the subdivided area after the intersection area is divided is merged into the sub-area corresponding to the monitoring point closest to the intersection area.
