Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
Example 1
step 101: determining the concentration distribution of the particles with different particle sizes in the indoor space; and
step 102: and controlling at least one equipment parameter of the purifying equipment according to the concentration distribution of the particles with different particle sizes in the indoor space.
Like this, owing to come to control clarification plant according to the concentration distribution of different particle diameter particulate matters in the indoor space, consequently, can carry out corresponding control to the particulate matter of different particle diameters to can improve purification efficiency and speed, high-efficient reach good purifying effect fast.
In the embodiment of the present invention, for example, the concentration distribution may refer to two-dimensional distributions of different particle diameters and a distribution of the number of each particle diameter.
In the embodiment of the present invention, the purification apparatus may be various types of purification apparatuses, such as an air purifier, a fresh air apparatus, or an air conditioning apparatus having an air purification function.
In the embodiment of the invention, the purifying equipment can be used for household use, and can also be used for commercial use or public use.
For example, the purification apparatus may be used in a residential environment, or may be used in a commercial environment such as an office, office building, mall, or a public environment such as a school.
In an embodiment of the present invention, the control method of the purge device may be performed by the purge device, for example, by a controller of the purge device.
In step 101, the concentration distribution of the particulate matter of different particle sizes in the indoor space is determined.
In the embodiment of the present invention, the particles having different particle sizes may be roughly classified, for example, large particle size particles and small particle size particles;
alternatively, the particulate matter of different particle sizes may be classified according to a uniform standard, for example, PM10 particulate matter, PM2.5 particulate matter, and the like.
In an embodiment of the present invention, the concentration distribution of particulate matter in the indoor space refers to the distribution of the concentration of particulate matter at different spatial positions in the indoor space, for example, at different heights in the indoor space.
The method for realizing step 101 will be described in detail below.
Fig. 2 is a flowchart of a method for implementing step 101 in embodiment 1 of the present invention, and as shown in fig. 2, the method includes:
step 201: acquiring data of the temperature and/or humidity of the indoor space; and
step 202: and determining the concentrations of the particles with different particle sizes corresponding to the temperatures and/or the humidities at different heights through a lookup table to obtain the concentration distribution of the particles with different particle sizes in the indoor space.
Therefore, the concentration distribution of the particulate matters with different particle sizes in the indoor space can be conveniently and quickly obtained through a table look-up method.
In the embodiment of the present invention, the data of the temperature and/or the humidity of the indoor space is obtained by, for example, a temperature sensor and/or a humidity sensor in the indoor space, which may be a plurality of sensors at different positions in the indoor space, or may be a sensor capable of moving in the indoor space.
In an embodiment of the present invention, the lookup table is a pre-established table and is stored in a database, for example.
For example, tests are performed in advance under different temperature and/or humidity conditions to obtain the concentrations of particles with different particle sizes at different heights, and the data are recorded and a lookup table is established.
Fig. 3 is a diagram showing an example of the lookup table in embodiment 1 of the present invention. As shown in fig. 3, the distribution position of the particulate matter gradually decreases as the temperature and humidity increase.
In step 202, the database is accessed and the lookup table is obtained in the database for comparison to determine the concentration of the various sized particles corresponding to the temperature and/or humidity at different heights.
For example, in the lookup table, for lower altitudes, the greater the humidity, the greater the concentration of the large-particle-size particulate matter corresponding thereto, and the smaller the humidity, the greater the concentration of the small-particle-size particulate matter corresponding thereto.
Thus, for example, the larger the humidity is, the larger the particle size of the particles will sink, and the distribution determined by the table look-up method can make the purification more targeted and the purification effect better.
FIG. 4 is a graph showing the distribution of the quantity concentration of indoor particulate matter with respect to ventilation and natural wind according to example 1 of the present invention; as shown in fig. 4, under a certain temperature and humidity condition, the distribution of the particles in the natural ventilation and the non-ventilation is different, and the purification equipment can be controlled according to the embodiment of the invention.
Fig. 5 is a flowchart of another method for implementing step 101 in embodiment 1 of the present invention, and as shown in fig. 5, the method includes:
step 501: acquiring data of the temperature and/or humidity of the indoor space; and
step 502: and inputting the temperature and/or humidity data and the height information into a first neural network model to obtain the concentration distribution of the particulate matters with different particle sizes in the indoor space.
Therefore, the concentration distribution of the particulate matters with different particle sizes in the indoor space is determined through the first neural network model, and the efficiency and the accuracy are high.
Step 501 is similar to step 201 and will not be described in detail here.
In step 502, the temperature and/or humidity data and the altitude information, such as the indoor altitude and/or the altitude of the floor where the purification apparatus is located, are input into the first neural network model to obtain the concentration distribution of the particles with different particle sizes in the indoor space.
Therefore, when the concentration distribution of the particles with different particle sizes in the indoor space is determined, the height factors such as indoor different heights and the heights of floors are considered, and correspondingly, different control strategies can be generated, so that the purification effect is stronger.
In the embodiment of the invention, the first neural network model is a model obtained by training in advance.
The following is an exemplary description of the training method of the first neural network model.
Fig. 6 is a flowchart of a method of training a first neural network model according to embodiment 1 of the present invention. As shown in fig. 6, the method includes:
step 601: inputting current temperature and humidity and height parameters;
step 602: training using the configured fully-connected neural network;
step 603: and after the model training is finished, saving the model.
Fig. 7 is a schematic diagram of the first neural network in the training of embodiment 1 of the present invention. As shown in fig. 7, the first neural network is a fully-connected neural network, where T represents temperature, RH represents relative humidity, H represents height, and P represents particulate matter concentration, that is, parameters of temperature, humidity and at least one height are input, and the predicted particulate matter concentration values with different particle sizes are output through the fully-connected neural network.
After the first neural network model is designed, the optimal value of the model needs to be found through training configuration, that is, the model is evaluated by a loss function, and the mean square error is used as a criterion for evaluating the model, for example, the loss function is expressed by the following formula (1):
Loss＝(p prediction —p Reality (reality) ) 2 (1)
Wherein Loss represents the Loss value, p Prediction Representing the concentration value, p, of particles output by the first neural network Reality (reality) The true value of the particulate matter concentration is indicated.
The corresponding gradient value can be obtained through reverse derivation, namely the correction gradient value is obtained, and after LOSS is minimized, the corresponding gradient value is more accurate; it is more accurate when the model is being used in the forward direction. After training is complete, the model may then be saved.
Fig. 8 is a flowchart of another method for implementing step 101 in embodiment 1 of the present invention, and as shown in fig. 8, the method includes:
step 801: acquiring numerical values of sensors for indoor particulate matters with different particle sizes; and
step 802: and fitting the concentration distribution of the particles with different particle sizes in the indoor space according to the numerical values of the sensors of the particles with different particle sizes in the indoor space.
Therefore, the concentration distribution of the particulate matters with different particle sizes in the indoor space is fitted through the actual detection value of the particulate matter sensor, and the result is more accurate.
In an embodiment of the invention, the plurality of sensors for detecting different particle sizes of the particulate matter is arranged at different heights in the chamber, for example, by a plurality of sensors in the chamber.
For example, multiple PM2.5 sensors and/or multiple PM10 sensors are disposed at different heights within the room.
In addition, a plurality of other sensors of different particle sizes may be included, such as PM0.5, PM1, PM2, PM3, PM4, PM5, and the like.
Fig. 9 is a schematic diagram of the concentration distribution of the fitted particles in the chamber according to example 1 of the present invention. As shown in fig. 9, for a certain particle size, a 3D distribution of the particle concentration in the chamber is fitted according to the particle concentration values at a plurality of positions measured by the sensor. In addition, similar fits can be made for other particle sizes.
In the above, the determination of the concentration distribution of the particulate matters with different particle sizes in the indoor space in step 101 is described, and in addition, in the embodiment of the present invention, the future concentration distribution of the particulate matters with different particle sizes in the indoor space can be predicted.
