The embodiment of the application provides a control method of a fresh air system.
Referring to fig. 2, fig. 2 is a schematic flow chart of an embodiment of a control method of a fresh air system according to the present application. The control method of the fresh air system is realized by the fresh air system.
Specifically, as shown in fig. 2, the control method of the fresh air system includes steps S101 to S104.
And S101, detecting the number of people in an air supply area of the fresh air system when the current regulation and control time is up.
Considering that the number of people in the air supply area of the fresh air system can change in practice, the fresh air volume delivered by the fresh air system is accurately controlled, and the fresh air volume of the fan of the fresh air system is periodically regulated and controlled in the embodiment of the application. The regulation and control period is dynamically adjusted according to the change condition of the number of people in the previous regulation and control period, so that the flexibility and the rationality of fresh air volume regulation are improved, and therefore, the method comprises a step S105 before the step S101.
And S105, determining the current regulation and control time according to the change condition of the number of people in the previous two continuous regulation and control periods.
In an embodiment, the determining the current regulation and control time according to the number of people in the previous two consecutive regulation and control periods specifically includes: if the number of people in the air supply area changes in the previous two continuous regulation and control periods, subtracting 1/n of the previous regulation and control period from the previous regulation and control period to serve as a current regulation and control period value, wherein n is a natural number which is more than 1 and less than 128; and calculating the sum of the previous regulation and control time and the current regulation and control period value to obtain the current regulation and control time.
In other words, if the number of people in the air supply area of the fresh air system changes in the previous two continuous regulation and control periods, the regulation and control period for regulating the fresh air volume is shortened no matter the number of people is increased or decreased. Specifically, the number of people in the air supply area of the fresh air system in the previous regulation and control period and the previous regulation and control period is obtained from the stored historical regulation and control data, the previous regulation and control time and the previous regulation and control period value are obtained, if the number of people in the air supply area of the fresh air system in the previous regulation and control period and the previous regulation and control period is changed, the current regulation and control period value is determined on the basis of the previous regulation and control period value, the sum of the previous regulation and control time and the current regulation and control period value is calculated, and the current regulation and control time is obtained. The method for determining the current modulation period value based on the previous modulation period value may be: and taking 1/n of the previous regulation period value, and subtracting 1/n of the previous regulation period from the previous regulation period value to serve as the current regulation period value and serve as the current regulation period value, wherein n is a natural number which is larger than 1 and smaller than or equal to 128. For example, if the number of people in the air supply area of the fresh air system in the previous regulation and control period and the previous regulation and control period is changed, the previous regulation and control period value is 20min, the previous regulation and control time is 13:00, and n is 4, then the current regulation and control period value is 5min, and the current regulation and control time is 13: 05.
In an embodiment, the step of, if the number of people in the blowing area changes in the two previous consecutive control periods, includes: subtracting a time unit from the previous regulation period value to obtain a current regulation period value; and calculating the sum of the previous regulation and control time and the current regulation and control period value to obtain the current regulation and control time.
That is, the manner of determining the current modulation period value based on the previous modulation period value may also be: and subtracting a time unit (for example, 1min) from the previous regulation period value to obtain a current regulation period value, and calculating the sum of the previous regulation period value and the current regulation period value to obtain the current regulation time.
In an embodiment, the determining the current regulation and control time according to the number of people in the previous two consecutive regulation and control periods specifically includes: if the number of people in the air supply area in the previous two continuous regulation and control periods is not changed, adding 1/n of the previous regulation and control period to be used as a current regulation and control period value, wherein n is a natural number which is more than 1 and less than or equal to 128; and calculating the sum of the previous regulation time and the current regulation period value to obtain the current regulation time.
Namely, if the number of people in the air supply area of the fresh air system is not changed in the previous two continuous regulation and control periods, the regulation and control period for regulating the fresh air volume is prolonged. Specifically, 1/n of the previous regulation period value is taken, the previous regulation period is added with 1/n of the regulation period to serve as the current regulation period value and serve as the current regulation period value, wherein n is a natural number which is larger than 1 and smaller than or equal to 128, and then the sum of the previous regulation time and the current regulation period value is calculated to obtain the current regulation time.
In further embodiments, for example, after the number of people in the air supply area has not changed in the previous two consecutive control periods, the method includes: adding a time unit (for example, 1min) to the previous regulation period value to serve as the current regulation period value; and calculating the sum of the previous regulation and control time and the current regulation and control period value to obtain the current regulation and control time.
That is, the manner of determining the current modulation period value based on the previous modulation period value may also be: and adding a time unit to the last regulation period value to obtain a current regulation period value, and calculating the sum of the last regulation period value and the current regulation period value to obtain the current regulation time.
In addition, for other situations that the number of people in the air supply area of the fresh air system changes in two continuous regulation and control periods, the previous regulation and control period value is used as the current regulation and control period value.
Therefore, the regulation and control period is dynamically shortened or prolonged by combining the change condition of the number of people in the previous regulation and control period, so that the fresh air volume is regulated more flexibly and reasonably.
Then, when the current regulation and control time arrives, the regulation and control mode can be triggered, specifically, the number of people in the air supply area of the fresh air system is detected firstly, an infrared sensor can be arranged in the air supply area of the fresh air system in advance, the communication connection between the fresh air system and the infrared sensor is established, then the number of people in the air supply area of the fresh air system is detected through an infrared detection technology, a camera can be arranged in the air supply area of the fresh air system, the communication connection between the fresh air system and the camera is established, then the number of people in the air supply area of the fresh air system is identified from the shot image through shooting the image of the air supply area of the fresh air system by utilizing.
And S102, comparing the number of people detected in the current regulation and control time with the number of people in the air supply area in the last regulation and control time.

And S103, if the number of people detected in the current regulation and control time is not consistent with the number of people in the air supply area in the last regulation and control time, determining the environmental quality index of the air supply area.
If the number of people in the air supply area of the fresh air system detected at the current regulation and control time is inconsistent with the number of people in the air supply area of the fresh air system detected at the last detection time, the number of people in the air supply area is changed, the fresh air quantity needs to be adjusted, and specifically, the environmental quality index of the air supply area is determined firstly.

In addition, a temperature sensor, a humidity sensor and a carbon dioxide concentration sensor can be mounted on the movable household equipment (such as a sweeping robot), the communication connection between the fresh air system and the movable household equipment is established, and the movable household equipment is controlled to move to detect the temperature, the humidity and the carbon dioxide concentration of the air supply area of the fresh air system so as to obtain more comprehensive environmental parameters.

wherein y represents an air quality index, x1Denotes the temperature, x2Denotes humidity, x3Represents the carbon dioxide concentration, a1Weight value a indicating temperature correspondence2Weight value a representing humidity3Represents the weight value of carbon dioxide, and a1+a2+a3＝1。
Therefore, the environmental quality index of the air supply area of the fresh air system can be calculated and obtained through the environmental parameters such as the temperature, the humidity, the carbon dioxide concentration and the like and the environmental quality index calculation formula.
Of course, if the environmental quality index is calculated according to other environmental parameters, a weight value may be set for each environmental parameter, and then the environmental quality index calculation formula is:

wherein x is1、x2、x3...xnRespectively representing each environmental parameter, a1、a2、a3...anRepresents the weight magnitude corresponding to each environment parameter, and a1+a2+a3…+an＝1。
