The preset voltage parameter may be set according to the operation condition of the fresh air system after the fresh air system is operated for multiple times, for example, an average value of the corresponding voltage parameters during the multiple times of operation may be obtained, or the corresponding voltage parameter during the most stable operation of the system may be obtained, or the corresponding voltage parameter during the fastest operation of the system may be obtained. Furthermore, the user voltage is typically mains power, i.e., power frequency Alternating Current (AC), the VSP voltage can be collected under direct current conditions, while the drive angle can be collected under both direct and alternating current conditions.
Step S20: determining a preset rotating speed corresponding to the acquired user voltage and the indoor environment temperature;
after the user voltage of the fresh air system and the indoor environment temperature of the indoor space acted by the fresh air system are obtained, the preset rotating speed corresponding to the obtained user voltage and the indoor environment temperature can be determined according to the preset relation between the user voltage and the indoor environment temperature and the rotating speed of the fresh air fan, and only one corresponding preset rotating speed can be determined according to the obtained user voltage, the obtained indoor environment temperature and the preset relation. Specifically, when the air conditioner leaves the factory, after system debugging, the preset relationship between the user voltage and the indoor environment temperature, which are preset according to the debugging result, and the rotating speed of the fresh air fan, and the preset relationship can be different for different manufacturers or different types of equipment, and can be adjusted according to specific conditions; the preset relationship between the user voltage and the indoor environment temperature and the rotating speed of the fresh air fan can be established according to the historical use condition of the user (such as whether the dirty blocking condition is monitored timely, whether the dirty blocking condition is judged mistakenly, whether the air quality is good and the like) so as to be used when the fresh air system operates next time, and the preset relationship can be updated in real time based on the use condition of each time. Of course, the preset relationship can also support user setting, user adjustment and the like, so that the user can modify the use condition based on different use environments to adapt to the application requirements of different users under different conditions.
In addition, the preset relationship may be a functional relationship established by taking the user voltage and the indoor environment temperature as independent variables and taking the rotation speed of the fresh air fan as a dependent variable, and the corresponding preset rotation speed may be calculated by applying the functional relationship according to the obtained user voltage and the indoor environment temperature, for example, the rotation speed of the fresh air fan may be calculated according to a difference value between the user voltage and the indoor environment temperature; the mapping relation between the user voltage and the indoor environment temperature and the rotating speed of the new fan can also be directly used, namely similar to XYZ three-dimensional coordinates, the user voltage is used as X, the indoor environment temperature is used as Y, the rotating speed of the new fan is used as Z, corresponding Z is distributed for each XY in advance, the Z can be directly inquired as long as the XY is known, and the Z and the XY are only in one-to-one correspondence without establishing a uniform functional relation. It should be noted that, in this embodiment, the user voltage and the indoor environment temperature are in a positive correlation with the rotation speed of the new fan, and the higher the user voltage is or the higher the indoor environment temperature is, the higher the rotation speed of the new fan is, so that the preset relationship should be set on the basis of the positive correlation.
Step S30: determining a dust removal strategy of the fresh air system according to the difference value of the rotating speed of the fresh air fan and a preset rotating speed;
after obtaining new fan rotational speed and confirming the preset rotational speed that corresponds with the user's voltage that obtains and indoor ambient temperature, can confirm the filthy stifled condition of new fan according to the new fan rotational speed and the difference of presetting the rotational speed, and then confirm corresponding dust removal strategy according to the filthy stifled condition that confirms, filthy stifled condition indicates the filthy stifled condition of the purification module of new trend system especially, purification module is the core component of new trend system, and after the long-time operation of new trend system, the easy laying dust of purification module, and not only can influence the fresh air volume after the laying dust and can breed bacterium and deposit virus and bacterium etc. when purification system laying dust, if open the new trend chance and cause the pollution to the room air, influence user's healthy.
Specifically, the dust collection condition of the purification module can be divided into three types according to the difference value between the rotating speed of the fresh air fan and the preset rotating speed based on the dust removal capacity of the fresh air system to the purification module: the first type is that the fresh air system can carry out self-purification, and the second type is that the fresh air system can not carry out self-purification and needs prompt to be replaced or cleaned in time; the third type is that the purification module has no dust deposition (or the influence degree of the dust deposition on the rotating speed of the fresh air fan is not very small yet reaching the degree of purification), and dust removal is not needed temporarily. The basis for dividing the dust accumulation condition of the purification module according to the difference value between the rotating speed of the fresh air fan and the preset rotating speed can be as follows: dividing according to the range of the difference value between the rotating speed of the fresh air fan and the preset rotating speed, or dividing according to the range of the difference value or the ratio value between the rotating speed of the fresh air fan and the preset rotating speed. When the dust accumulation condition of the purification module divided according to the difference value of the rotating speed of the fresh air fan and the preset rotating speed is a first kind of condition, the fresh air system can sterilize the purification module by turning on the sterilizing lamp, meanwhile, the fresh air quantity of the fresh air system can be kept by increasing the rotating speed of the fresh air fan, and at the moment, the dust removal strategy of the fresh air system is determined to be turning on the sterilizing lamp, and the rotating speed of the fresh air fan is increased; when the dust accumulation condition of the purification module divided according to the difference value between the rotating speed of the fresh air fan and the preset rotating speed is a second kind of condition, outputting prompt information to prompt the cleaning or replacement of the purification module, continuously monitoring the difference value between the rotating speed of the fresh air fan and the preset rotating speed when the fresh air system operates next time, and determining the dust removal strategy of the fresh air system as the output prompt information to prompt the cleaning or replacement of the purification module; when the dust accumulation condition of the purification module divided according to the difference value between the rotating speed of the fresh air fan and the preset rotating speed is the third kind of condition, the current rotating speed can be kept, corresponding dust removal treatment on the purification module is not needed temporarily, but when the fresh air system is started next time, the difference value between the rotating speed of the fresh air fan and the preset rotating speed needs to be continuously monitored, the dust accumulation of the fresh air system is prevented from being unused for a long time, and at the moment, the dust removal strategy of the fresh air system is determined to enable the fresh air fan to keep the current rotating speed to operate.
On the basis, historical use information such as time and period of each use of the fresh air system can be recorded, so that a dust removal strategy suitable for different users and different use environments is determined based on the historical use information and/or a difference value between the rotating speed of the fresh air fan and a preset rotating speed, and the use requirements of different users are met.
Step S40: and controlling the fresh air system to execute corresponding dust removal operation according to the determined dust removal strategy.
After the dust removal strategy of the fresh air system is determined according to the difference value between the rotating speed of the fresh air fan and the preset rotating speed, the fresh air system is controlled to execute corresponding dust removal operation according to the determined dust removal strategy, so that the air output and the air output quality in the current operation can be ensured. Specifically, the determined dust removal strategy is to turn on a bactericidal lamp, increase the rotating speed of a fresh air fan, control a fresh air system to carry out dust removal operation of turning on the bactericidal lamp and increasing the rotating speed of the fresh air fan so as to remove dust from the fresh air system; when the determined dust removal strategy is to output prompt information to prompt the cleaning or replacement of the purification module, the fresh air system can be controlled to execute dust removal operation for outputting the prompt information to prompt the cleaning or replacement of the purification module; and when the determined dust removal strategy is to enable the fresh air fan to keep the current rotating speed to operate, the fresh air system can be controlled to execute the dust removal operation of keeping the fresh air fan to operate at the current rotating speed.
In addition, when the fresh air system is started again, the difference value between the rotating speed of the fresh air fan and the preset rotating speed needs to be continuously monitored so as to update the dust removal strategy in real time, and the fresh air system is effectively controlled to execute corresponding dust removal operation in time.
In this embodiment, the user voltage of the fresh air system and the rotation speed of the fresh air fan are acquired, the indoor environment temperature is acquired, the preset rotation speed corresponding to the acquired user voltage and the indoor environment temperature is determined, the dust removal strategy of the fresh air system is determined according to the difference between the rotation speed of the fresh air fan and the preset rotation speed, and then the fresh air system is controlled to execute the corresponding dust removal operation according to the determined dust removal strategy. Corresponding dust removal strategy can be accurately formulated according to the difference value of the rotating speed of the fresh air fan and the preset rotating speed, the temperature of the coil pipe does not need to be monitored, or a plurality of pressure devices are not added for pressure detection, the situation that the filth blockage cannot be accurately judged to formulate the corresponding dust removal strategy due to the fact that factors such as error or unstable pressure exist easily in the coil pipe temperature detection is avoided, and the dust removal reliability of the fresh air system is improved.

The pre-divided difference range can be determined according to the dedusting processing capacity of the system, the difference range which can be reached by the difference between the rotating speed of the fresh air fan and the preset rotating speed and the like. The number of the divided difference value ranges and the length of each range are not limited, and the difference value ranges can be divided according to specific situations.
In a specific embodiment, a range in which the difference between the rotating speed of the fresh air fan and the preset rotating speed is located is preferably divided into four range areas in advance, so that the difference range in which the difference between the rotating speed of the fresh air fan and the preset rotating speed is located is determined according to the divided range areas. The method specifically comprises the following steps: presetting a first preset threshold, a second preset threshold and a third temperature threshold, and comparing the difference value of the rotating speed of the fresh air fan and the preset rotating speed with the first temperature threshold and the second temperature threshold to determine the range of the difference value of the rotating speed of the fresh air fan and the preset rotating speed.

After the color of the air quality display lamp is determined, the step of controlling the fresh air system to perform the corresponding dust removal operation according to the determined dust removal strategy and the step of controlling the air quality display lamp to display in the determined color may be performed simultaneously or sequentially, which is not limited in this embodiment.
Certainly, in order to avoid that the air quality display lamp can not mark the air quality and/or the dust accumulation condition when damaged, a plurality of air quality display lamps can be arranged simultaneously, and the plurality of arranged air quality display lamps can display the same color through color conversion so as to perform the mutual verification function, and can also respectively mark different air qualities.
