Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, the automatic control method for a cigarette making machine based on multi-sensor fusion in the present embodiment includes the following steps 1 to 6:
step 1, acquiring real-time temperature data near a range hood, and calculating to obtain a control coefficient of temperature to a range hood wind shield; wherein the control coefficient of the temperature to the wind shield of the range hood is marked as kt：
Figure BDA0001414594780000041
ktRepresenting the control coefficient of temperature to the wind shield of the range hood, t being the collected real-time temperature data, kt∈(0,100)；
Because the temperature of the kitchen is close to the room temperature, the temperature near kitchen utensils such as a household wok can reach about 60 ℃, the temperature of the indoor air temperature can not exceed 42 ℃ at most under the normal condition, and the most comfortable temperature of a human body is 25 ℃, the temperature near the range hood is preprocessed so as to be converted into a control coefficient of the temperature to the range gear of the range hood;
control coefficient k of range hood for the temperaturetThe formula (c) is illustrated as follows:
when the real-time temperature data t near the range hood is lower than 25 ℃, the set temperature has no influence on the range hood wind shield;
when the real-time temperature data t near the range hood is between 25 ℃ and 42 ℃, the set temperature has influence on the range hood wind shield, and the control coefficient condition of the temperature on the range hood wind shield at the moment needs to be judged;
when the real-time temperature data t near the range hood is higher than 42 ℃, the temperature belongs to the alarm temperature (or called as early warning temperature) of the range hood, and the temperature has the maximum influence on the range hood gear under the condition, namely, the control coefficient of the temperature on the range hood gear is the maximum at the moment;
step 2, acquiring real-time humidity data near the range hood, and calculating to obtain a control coefficient of humidity to the range hood; wherein, the control coefficient of the humidity to the wind shield of the range hood is marked as kh：
Figure BDA0001414594780000051
khRepresenting the control coefficient of humidity to the wind shield of the range hood, h being the collected real-time humidity data, kh∈(0,100)；
Because the humidity of the kitchen is higher than that of the outside air, the humidity of the kitchen can reach over 90 percent under the conditions that a user boils water or cooks soup and the like, and at the moment, the human body is not very sensitive to the humidity; only under the conditions of overhigh humidity and overlow humidity, discomfort exists, and the condition of overhigh humidity is not adjustable by the range hood, so in the embodiment, under the condition that the humidity of the air near the range hood is lower than 60%, the influence of the humidity on the control of the range hood gear is 0, and when the humidity of the air near the range hood is higher than 60%, the influence of the humidity on the control of the range hood gear presents a positive correlation trend, and the higher the humidity is, the larger the influence on the range hood gear is increased;
step 3, acquiring real-time oil smoke concentration data near the range hood, and calculating to obtain a control coefficient of the oil smoke concentration to the range hood; wherein, the control coefficient of the smoke concentration to the smoke machine wind gear is marked as kl：
Figure BDA0001414594780000052
klThe control coefficient of the smoke concentration to the wind gear of the smoke machine is shown, l is the collected real-time smoke concentration data, kl∈(0,100)；
Because the oil smoke concentration in the kitchen most directly represents the air quality of the kitchen, after the data collected by the sensor is quantized into percentage, if the situation that the oil smoke concentration data near the smoke machine is below 5% is monitored, a user cannot detect that the oil smoke brings discomfort, the control coefficient of the wind gear of the smoke machine is set to be 0 for the oil smoke concentration data lower than 5%, and the oil smoke concentration data near the smoke machine is greater than 30%, the human body cannot tolerate the oil smoke condition under the oil smoke concentration condition, so the wind gear control coefficient of the smoke machine is set to be the maximum by setting the oil smoke concentration of 30% or more in the embodiment, namely the wind gear control coefficient under the condition is set to be 100;
step 4, calculating to obtain an influence coefficient of the environmental air condition on the wind shield of the range hood according to the obtained control coefficient of the temperature on the wind shield of the range hood, the control coefficient of the humidity on the wind shield of the range hood and the control coefficient of the oil smoke concentration on the wind shield of the range hood; wherein the influence coefficient of the ambient air condition on the wind shield of the range hood is marked as ka：
Figure BDA0001414594780000061
ktControl coefficient, k, of temperature to damper of a range hoodhCoefficient of control of humidity to damper, klThe control coefficient of the smoke concentration to the wind gear of the smoke machine is obtained; k is a radical oft、khAnd klAre each 0 to 100, kaA value between 1 and 99;
step 5, judging the human body by the cigarette machineThe cigarette making machine is automatically controlled, whether a human body is located near the cigarette making machine or not is identified, and a final influence coefficient of the human body on the wind gear of the cigarette making machine is obtained according to an identification result of whether the human body is located near the cigarette making machine or not; wherein the final influence coefficient of the human body on the wind shield of the smoke machine is marked as kf：
Figure BDA0001414594780000062
Through monitoring and judging, the range hood can judge whether people exist nearby or no people exist nearby; when no person is near the cigarette machine, the human body does not have any influence on the control of the wind gear of the cigarette machine, so that in the case, the wind gear control coefficient of the cigarette machine is set to be reduced to 25 percent, thereby realizing that when no person is near the cigarette machine, the too high wind gear of the cigarette machine is not needed, and at the moment, the final influence coefficient of the human body on the wind gear of the cigarette machine is set to be 0.75 ka(ii) a When a person is near the cigarette machine, the cigarette machine is set to provide a complete wind gear working state, and at the moment, the final influence coefficient of the human body on the wind gear of the cigarette machine is ka；
And 6, setting a preset gear threshold value aiming at the wind gear of the cigarette machine, and obtaining the wind gear of the corresponding cigarette machine according to the preset gear threshold value and the final influence coefficient of the human body on the wind gear of the cigarette machine.
For example, in the present embodiment, the preset gear threshold values are set to 20, 45, and 70, respectively; calculating the final influence coefficient k of the human body on the wind shield of the smoke machinefComparing with each preset gear threshold value to judge which wind gear is started by the range hood; specifically, the method comprises the following steps:
final influence coefficient k of human body to fume exhauster wind shieldfLess than 20, i.e. kf<20, closing the range hood;
final influence coefficient k of human body to fume exhauster wind shieldfWhen it is between 20 and 45, i.e. 20 ≦ kfStarting the first wind power of the range hood when the wind power is less than or equal to 45 degrees;
final influence coefficient k of human body to fume exhauster wind shieldfWhen it is between 45 and 70, i.e. 45<kfStarting a second-gear wind power of the range hood when the wind power is less than or equal to 70 degrees;
final influence coefficient k of human body to fume exhauster wind shieldfAbove 70, i.e. kf>At 70, the maximum wind power of the range hood is started.
In addition, as an improvement measure, the automatic control method for the cigarette making machine according to the embodiment can also record the next operation of the user as a correction operation within a preset time after the wind gear of the cigarette making machine is adjusted, and automatically adjust the step length of a preset threshold interval for the wind gear of the cigarette making machine to obtain a new adjusted preset threshold matched with the habit of the user; for example, the preset time here is 10 s; wherein the adjusted step size is marked as deltaka：
Figure BDA0001414594780000071
Wherein, x represents the adjusted times of the step length, rand represents the random error, and the value range of rand is (0, 1); the adjusted preset gear threshold values are respectively 20-x.deltaka、45-x·δkaAnd 70-x.deltaka(ii) a Wherein: in the case after the step size is adjusted:
final influence coefficient k of human body to fume exhauster wind shieldfLess than 20-x.deltakaWhen the cigarette is in use, the cigarette machine is closed;
final influence coefficient k of human body to fume exhauster wind shieldfAt 20-x.deltakaTo 45-x.deltakaStarting the first-gear wind power of the range hood;
final influence coefficient k of human body to fume exhauster wind shieldfAt 45-x.deltakaTo 70-x.deltakaIn the meantime, the second-gear wind power of the range hood is started;
final influence coefficient k of human body to fume exhauster wind shieldfHigher than 70-x.deltakaWhen the range hood is started, the maximum wind power of the range hood is started.
For example, for the adjusted step size δkaExamples are as follows:
assuming that the step size has been adjusted 3 times, i.e. x is 3, and the random error rand is 0.5, the step size after this time, i.e. the 4 th adjustment

Correspondingly, the adjusted preset gear threshold values are respectively 20-x.deltaka、45-x·δkaAnd 70-x.deltaka(ii) a Namely, the adjusted new preset gear threshold values are respectively:
20-x·δka＝20-3x6.5＝0.5；45-3x6.5＝25.5；70-x·δka＝70-3x6.5＝50.5；
wherein: in the case after the step size is adjusted:
