According to the fresh air machine filter screen life control system provided by the embodiment of the application, the indoor particulate matter concentration value and the outdoor particulate matter concentration value of the fresh air machine 102 are calculated by using the server 106 to obtain the purification efficiency of the fresh air machine 102, so that whether the filter screen of the fresh air machine 102 needs maintenance or not can be judged, including cleaning or replacement and the like, and when the filter screen is judged to need to be maintained, a command is issued to the fresh air machine 102 to enable an indicating device of the fresh air machine 102 to carry out maintenance prompt.

Further, through setting the collection period of indoor particle concentration, personalized recommendation of the maintenance time of the fresh air fan filter screen in different areas can be realized, and the problems of poor user experience and economic loss under the condition of fixed recommendation duration are avoided. In one implementation of any of the foregoing embodiments, the sweeping robot 104 is designed to: and in the set area, moving along the planned route, and collecting indoor particulate matter concentration values at different set positions of the route to obtain a plurality of indoor particulate matter concentration values.
Self-moving sweeping robot 104 includes intelligent moving robots, such as sweeping robots; the set area and the planned route can be the sweeping area and the sweeping route of the sweeping robot, or the set area and the acquisition route in the acquisition mode; the implementation mode of the embodiment of the application can obtain more accurate indoor particulate matter concentration values, thereby accurately judging the maintenance time of the filter screen.
The fresh air machine 102 calculates the average value of a plurality of collected indoor particulate matter concentration values of the sweeping robot in a set area along a planned route, calculates the purification efficiency of the filter screen according to the calculated average value and the outdoor particulate matter concentration value, and judges whether the filter screen needs maintenance by judging whether the purification efficiency meets the conditions.
In addition, the related art generally calculates the purifying efficiency of the filter screen according to the concentration of dirt before and after filtering, in this way, a sensor needs to be installed at the position before and after filtering the filter screen of the fresh air fan 102, which is costly, and the sensor occupies the space of the fresh air fan 102. According to the application, the indoor particulate matter concentration value is collected by the sweeping robot 104 in the intelligent home network, so that on one hand, the accuracy of collecting the indoor particulate matter concentration value can be improved, and on the other hand, a sensor is not required to be arranged on the fresh air machine 102, and the cost is saved.
Alternatively, the plurality of sweeping robots 104 disposed in different areas of the room may all obtain indoor particulate matter concentration values, the fresh air fan 102 is interconnected with the plurality of sweeping robots 104, an average value is calculated for the indoor particulate matter concentration values collected by the plurality of sweeping robots 104, the purifying efficiency of the filter screen is calculated according to the calculated average value and the outdoor particulate matter concentration value, and whether the filter screen needs maintenance is judged by judging whether the purifying efficiency meets the condition.

Specifically, the server 106 sends a judging request to the sweeping robot 104 according to a set period, and the sweeping robot 104 responds to the request to collect the indoor particulate matter concentration value, so that the sweeping robot 104 can save more energy, and meanwhile, the cleaning condition of the filter screen can be timely judged, the replacement or cleaning of the filter screen by the fresh air fan 102 with a fixed duration is avoided, and the use problems of small air output, poor cleaning efficiency, high noise and the like caused by cleaning or replacing the filter screen with the fixed duration are avoided.
The setting periods of different fresh air machines 102 may be the same or different, and the setting periods of the fresh air machines 102 in the same area are generally the same.
Further, the server 106 is further configured to determine the setting period according to the usage information of the fresh air machine 102 and/or the type of the filter screen.
Optionally, when the fresh air machine 102 is used for the first time, the communication module sends the usage location information (province name or positioning information, etc.) and/or the filter screen type to the server 106, and the server determines the detection period of the service life of the filter screen of the fresh air machine 102 according to the filter screen type of the fresh air machine 102 and/or the usage location information.

TABLE 1 Filter screen type-usage ground-set periodic Table
In another specific implementation, the server determines a detection period for a filter life of the new fan 102 based on the new fan 102 usage information, as shown in table 2:
TABLE 2 fresh air machine 102 usage floor-set periodic Table
| Setting a period | |
| Liaoning (Liaoning) | A first set period |
| Shanxi style food | A second set period |
| Guangdong aspect | Third setting period |
| … | … |
| Hebei river | Nth set period |
Further, the server 106 is also configured to:
calculating the average value of the concentration values of the plurality of indoor particles to obtain the average value of the concentration of the indoor particles;
calculating the purification efficiency of the filter screen according to the indoor particle concentration average value and the outdoor particle concentration value;
comparing the purification efficiency with a set threshold;
when the purification efficiency is smaller than the set threshold value, it is determined that maintenance of the filter device is required.
In the implementation mode, the server calculates the average value of a plurality of indoor particulate matter concentration values collected by the sweeping robot in a set area along a planned route, calculates the purification efficiency of the filter screen according to the calculated average value and the outdoor particulate matter concentration value, compares the purification efficiency with a set threshold value, considers that the purification efficiency of the filter screen is poor under the condition that the purification efficiency is smaller than the set threshold value, and needs to replace or clean the filter screen, otherwise, considers that the purification efficiency of the filter screen meets the requirement under the condition that the purification efficiency is larger than the set threshold value, and does not need to be maintained.
The two implementation modes of the embodiment of the application can obtain more accurate indoor particulate matter concentration values. The sweeping robot 104 only needs to have the functions of collection and transmission (indoor particle concentration), and the average value operation is put in the control terminal 108, so that the calculation load is not increased.
The novel fan filter screen life control system collects indoor particulate matter concentration values at different set positions of a route to obtain a plurality of indoor particulate matter concentration values, and the implementation mode of the embodiment achieves personalized recommendation of maintenance time of filtering devices in different areas, and avoids the problems of poor user experience and economic loss under fixed recommendation duration (common advice).
Specifically, the server side stores the usage information of the fresh air fan 102 and the detection period suitable for the region correspondingly, and can acquire the corresponding detection period according to the usage information when needed. The detection period is relatively short for areas with serious pollution, and relatively long for areas with light pollution.
When the filter screen is dirty and blocked, the purification efficiency is reduced compared with the purification efficiency in the clean state of the filter screen. The outdoor fresh air enters the room after being filtered by the filter screen, and the change condition of the indoor particulate matter concentration value relative to the outdoor particulate matter concentration value can reflect the purification efficiency of the filtering device. For the filter screen with the same specification, under the condition that the purification efficiency is lower than the set threshold value, the filter screen is considered to be dirty and blocked, and the filtration efficiency is poor, and the filter screen is required to be cleaned or replaced at the moment. For filter screens with different specifications, the threshold value is generally set to be different.
The fresh air machine 102 is provided with a prompt device, and in one implementation of the embodiment of the application, the prompt device comprises any one or more of a display device, a voice device and a communication module; the fresh air machine 102 sends a maintenance message to the sweeping robot 104 or a control terminal for maintenance prompt through a communication module, wherein the control terminal is used for controlling the operation of the fresh air machine 102 and/or the sweeping robot 104.
When the fresh air fan 102 determines that the purifying efficiency of the filter screen is too low, the prompting device is enabled to work, such as flashing a light, and a buzzing prompt, etc., so as to prompt a user to replace or clean the filtering device. Or the information required to be maintained of the filtering device is fed back to the server through the communication module and pushed to the control terminal, so that a user is prompted to replace or clean the filtering device. Or simultaneously, the normal use of the filter screen of the fresh air ventilator 102 is ensured under the condition that the user does not need to reset the time of the filter screen.
In one implementation manner of the embodiment of the present application, the fresh air fan 102 calculates the purification efficiency of the filtering device by adopting the following formula:
E＝(V outdoor unit -V)/V Outdoor unit ；
Wherein V is Outdoor unit The outdoor particulate matter concentration value is represented, V is represented by an average value of the indoor particulate matter concentration, E is represented by purification efficiency,/is represented by.
In one implementation manner of the embodiment of the present application, the filtering device includes a primary filter screen, a middle-efficiency filter screen, and a high-efficiency filter screen, where in the case where the indoor particulate matter concentration value and the outdoor particulate matter concentration value are PM2.5 values, in the case where the purification efficiency is less than the set threshold value, the server 106 is further configured to:
reminds to change high-efficient filter screen, reminds to wash primary filter screen and medium-efficient filter screen.
