Detailed Description
The present invention will now be described in more detail with reference to the accompanying drawings, in which the description of the invention is given by way of illustration and not of limitation. The various embodiments may be combined with each other to form other embodiments not shown in the following description.
Example one
The embodiment provides a monitoring method for fresh air equipment, and aims to solve the problem that the function of reminding to replace a filter plate is not set in the conventional fresh air equipment. Referring to fig. 1, the monitoring method specifically includes the following steps.
And S10, acquiring the operation time period of the fresh air equipment, and recording the duration of the operation time period as T1. The operation time period has a start time ta and an end time tb, and the fresh air device only operates one circulation mode in the operation time period and is recorded as a mode A. It should be noted that the fresh air device has one or more circulation modes, which are not limited herein.
And S20, acquiring the air outlet quality of the fresh air equipment in the operation time period. Because the air outlet quality of the fresh air equipment is related to the use of the filter plate, the air outlet quality should be referred to when the accumulated time length T3 is calculated, so that the obtained accumulated time length T3 is closer to the use state of the corresponding filter plate.
And step S30, inquiring and recording the filter plates corresponding to the mode A as the operation filter plates, wherein each operation filter plate has a filter type, a use requirement and an accumulated duration T2 corresponding to the starting time ta. Since the fresh air device has one or more circulation modes and the participating filter boards may be different if the circulation modes are different, it is necessary to determine the operating filter board in mode a, i.e. the operating filter board is the filter board participating in the cleaning operation.
The service requirement may be a service life T0, which may be the time the filter panel can operate without changing the filtration efficiency, filtration type.
It should be noted that the accumulated time period T2 is a virtual time period, which is not equal to the total actual operation time period of the filter board, but the accumulated time period T2 is related to the filtering type and the outlet air quality, so that the actual state of the filter board can be better described.
And S40, obtaining the accumulated time length T3 corresponding to the starting time tb of each running filter plate based on the air outlet quality, the filter type, the time length T1 and the accumulated time length T2. It is worth to be noted here that, when the next operation period comes, the accumulated time period T3 is T2 of the next operation period.
Step S50, judging whether the accumulated time length T3 of each filter board is matched with the use requirement, if so, executing no operation or acquiring the next operation time period of the fresh air equipment, and executing the method circularly; if not, go to step S60.
And step S60, generating an alarm signal to remind the corresponding filter board to be replaced. The fresh air equipment can be provided with an alarm which responds to the alarm signal to give an alarm, and the alarm form is not limited to sound alarm and light alarm; the fresh air equipment can also communicate with the background, and the background responds to the alarm signal to send a message to a mobile terminal of a user.
In conclusion, the accumulated time length T3 is obtained through calculation and is compared with the use requirement to quickly determine whether the corresponding filter plate needs to be replaced, so that the indoor environment is prevented from being influenced and the cost is reduced; the accumulated time length T3 is related to the air outlet quality and the filtering type, so that the accumulated time length T3 better accords with the actual situation of the corresponding filter plate, and the utilization rate of each filter plate is improved.
It is worth mentioning that the steps of the method are performed on the basis of the execution device. Specifically, the execution device may be a server, a client, a processor, or the like, but the execution device is not limited to the above type.
Example two
The embodiment provides a monitoring method for fresh air equipment, and is performed on the basis of the first embodiment, with reference to fig. 1 and fig. 2. Specifically, step S10 includes steps S101 to S105.
Step S101, receiving the trigger information and setting the receiving time as the ending time tb of the processing time period. It is noted that the trigger information may be a shutdown signal or a cycle mode switching signal.
For the stop signal, the stop signal is a signal sent by the fresh air device when the fresh air device stops operating, when the fresh air device is turned off or in standby, the stop signal can be regarded as stop, and when the trigger information is the stop signal, the corresponding stop time is the termination time tb. The circulation mode switching signal is a signal generated when the fresh air device switches the circulation mode, and when the trigger information is the circulation mode switching signal, the circulation mode is different before and after the termination time tb.
And S102, inquiring the starting time t2 and the switching time t3 of the previous circulation mode. The starting time t2 is the time when the fresh air device starts to operate.
Step S103, determining whether t2 is greater than t3, if yes, performing step S104, otherwise, performing step S105.
In step S104, the power-on time t2 is used as the start time ta of the operation time period, that is, ta is t 2. It can be understood that when t2 > t3, it indicates that the fresh air device is not switched from power-on operation to tb, and therefore the time period is t2 to tb during the operation.
In step S105, the switching time t3 of the previous cycle mode is used as the start time ta of the operation time period, that is, ta is t 3. It can be understood that when t2 is less than or equal to t3, it indicates that the fresh air device is operated to tb when being powered on, and the circulation mode is switched, and the operation time period is t3 to tb because the fresh air device only performs one circulation mode in the operation time period.
By the technical scheme, the starting time ta and the ending time tb of the operation time period can be accurately confirmed, and the adjacent operation time periods are not overlapped, so that the accuracy of the accumulated time length T3 is improved.
Further, when the trigger information is the cycle switching signal, the step S101 further includes steps S1011 to S1013.
Step S1011, receiving the carbon dioxide monitoring value q. It is worth explaining here that this new trend equipment has the carbon dioxide sensor, and this carbon dioxide sensor can set up in the inside or the outside of new trend equipment, and it only need with new trend equipment be located same space can. The carbon dioxide sensor is used for monitoring the carbon dioxide concentration of a space where the carbon dioxide sensor is located and recording the carbon dioxide concentration as a carbon dioxide monitoring value q, the carbon dioxide sensor can continuously acquire the carbon dioxide monitoring value q and can also be used for acquiring the carbon dioxide monitoring value q according to a preset frequency, and the carbon dioxide sensor is also connected with the executing equipment of the method, so that the executing equipment of the method can receive the carbon dioxide monitoring value q.
Step S1012, judging whether the carbon dioxide monitoring value q is matched with the current circulation mode, if not, executing step S1013; if so, no operation may be performed. It is worth noting here that each cycle mode has a requirement for a carbon dioxide monitoring value q.
And S1013, controlling the fresh air equipment to switch to a circulation mode matched with the carbon dioxide monitoring value q and outputting a circulation mode switching signal. Specifically, a current circulation mode is recorded as a mode A, a circulation mode matched with the carbon dioxide monitoring value q is inquired and recorded as a mode B, then the mode A is switched to the mode B, and a corresponding circulation mode switching signal is output.
Through this technical scheme, because the circulation mode of new trend equipment carries out the self-switching based on indoor carbon dioxide content usually, consequently confirm the switching of circulation mode through carbon dioxide monitoring value q, have accurate advantage.
EXAMPLE III
The embodiment provides a monitoring method for fresh air equipment, and is performed on the basis of the first embodiment or the second embodiment.
Referring to fig. 6, the fresh air device can be selected as a fresh air machine 1, and the filter plates inside the fresh air device include a first primary filter plate 11, a second primary filter plate 12, a middle-stage filter plate 13 and a high-stage filter plate 14. Wherein, the first primary filter plate 11 and the second primary filter plate 12 are both used for filtering large-particle substances such as feather, scurf, dust and the like, and can be made of gauze and other materials; the middle stage filter plate 13 is used for filtering particulate matters with PM2.5 above, and can adopt the combination of sponge and active carbon; the advanced filter plate 14 is used for filtering particulate matters and bacteria of PM 0.3-2.5, and can adopt a combination of melt-blown cloth and activated carbon.
The circulation mode comprises an inner circulation and an inner and outer circulation, and the inner and outer circulation is a combination of the inner circulation and the outer circulation. In the internal circulation, the air passes through the first primary filter plate 11, the treatment chamber 15 and the advanced filter plate 14 in sequence; in the outer circulation, the air passes through the second primary filter plate 12, the middle filter plate 13, the process chamber 15, and the high filter plate 14 in this order. When the carbon dioxide monitoring value q is larger than a preset threshold value, the fresh air device has an internal circulation switched to an internal circulation and an external circulation, and the threshold value can be set to 2000 ppm.
As an alternative solution, referring to fig. 4 and 6, the step S20 includes a step S201 and a step S202.
Step S201, inquiring the PM2.5 monitoring value d in the running time period T1, and forming a processing group. It is worth noting that the PM2.5 monitoring value d is measured by a PM2.5 sensor, which may be disposed within the process chamber 15 of the fresh air machine 1. The PM2.5 monitoring value d collected by the PM2.5 sensor can be continuously carried out or carried out according to a preset frequency, and the PM2.5 sensor is also connected with the execution equipment of the method, so that the execution equipment of the method can receive the PM2.5 monitoring value q.
And S202, calculating the processing group to obtain an effective value, wherein the effective value is an arithmetic mean value or a root mean square value. As a preferable technical solution, in step S202, before the calculation, the processing group may be subjected to a method such as the grassbs method, the dixon method, and the neel method, and data that does not meet the discretization requirement may be deleted to obtain a processing group that meets the discretization requirement, so as to improve the accuracy of the effective value.
Further, as shown in fig. 5 and 6, step S40 includes steps S401 to S403.
And S401, obtaining coefficients k of the operating filter plates based on the air outlet quality and the filter type. For example: when the effective value is less than 30 mug/m 3, the coefficients k of the first primary filter plate 11 and the second primary filter plate 12 are both 1, and the coefficients k of the middle-stage filter plate 13 and the high-stage filter plate 14 are both 0.7; when the effective value is less than 60 mug/m 3 and less than or equal to 30 mug/m 3, the coefficients k of the first primary filter plate 11 and the second primary filter plate 12 are both 1, and the coefficients k of the middle-stage filter plate 13 and the high-stage filter plate 14 are both 0.95; when the effective value is less than or equal to 60 mu g/m3 and less than 150 mu g/m3, the coefficients k of the first primary filter plate 11 and the second primary filter plate 12 are both 1, and the coefficients k of the middle-stage filter plate 13 and the high-stage filter plate 14 are both 1; when the effective value is less than or equal to 150 mug/m 3, the coefficients k of the first primary filter plate 11 and the second primary filter plate 12 are both 1, and the coefficients k of the middle-stage filter plate 13 and the high-stage filter plate 14 are both 1.2. It should be noted that the relationship between the coefficient k and the effective value of each filter plate can be adjusted accordingly according to the actual situation.
Step S402, calculating an equivalent time duration Tx, Tx-T1 × k corresponding to the time duration T1 for each filter board. For example, when the effective value is 30 μ g/m 3-60 μ g/m3 and the duration T1 is 1h, Tx of the first and second preliminary filter plates 11 and 12 is (1h) × 1 ═ 1 h; tx (1h) × 0.95h ═ 0.95h for the intermediate filter plate 13 and the advanced filter plate 14.
In step S403, the accumulated time length T3 corresponding to the termination time tb of each filter plate is obtained according to an update formula, where the update formula is T3 ═ T2+ Tx. For example, if the accumulated time period T2 of the middle filter board 13 is 150h and the equivalent time period Tx is 0.95h, the accumulated time period T3 is (150h) + (0.95h) is 150.95 h.
Further, the step S50 may include: it is determined whether the accumulated time period T3 is less than the service life T0. It is worth noting that the service requirement has a service life of T0. For example: the service life T0 of the first primary filter plate 11 and the second primary filter plate 12 is 3000 h; the service life T0 of the middle-stage filter plate 13 is 2000 h; the service life T0 of the advanced filter board 14 is 1000 h.
Since the damage of the high-grade filter plate 14 and the middle-grade filter plate 13 by the air with good quality is small, and the damage of the high-grade filter plate 14 and the middle-grade filter plate 13 by the air with poor quality is large, the accumulated time length T3 of the corresponding filter plate is closer to the time length during the experiment through the effective value adjusting coefficient k.

Referring to fig. 6, both the exhaust fan 17 and the outlet fan 16 are disposed in the fresh air machine 1. When q is less than 900ppm, the speed of the exhaust fan 17 is 20% of the full speed, and the speed of the exhaust fan 16 is 20% of the full speed; when q is more than or equal to 900ppm and less than 1500ppm, the speed of the exhaust fan 17 is 30% of the full speed, and the speed of the air outlet fan 16 is 35% of the full speed; when q is more than or equal to 1500ppm and less than 2000ppm, the speed of the exhaust fan 17 is 40% of the full speed, and the speed of the air outlet fan 16 is 50% of the full speed; when q is less than 2500ppm and is less than or equal to 2000ppm, the speed of the exhaust fan 17 is 60% of the full speed, and the speed of the air outlet fan 16 is 70% of the full speed; when the quantity q is less than or equal to 2500ppm, the speed of the exhaust fan 17 is 80% of the full speed, and the speed of the exhaust fan 16 is 90% of the full speed.
It is worth to be noted here that when q is equal to or greater than 2000ppm, the valve 18 on the first channel is opened and the fresh air device performs internal and external circulation; when q < 2000ppm, the valve 18 on the first channel is closed and the new fan 1 performs an internal circulation.
Further, the method also comprises: calculating the average speed v1 of the exhaust fan 17 and the average speed v2 of the exhaust fan 16 in the processing time period; the coefficient k in step S401 is then adjusted based on the average speed v1 of the exhaust fan 17 and the average speed v2 of the exhaust fan 16. For example: when the average speed v1 and the average speed v2 of the air outlet fan 16 are both less than 50% of the corresponding full speed, the coefficient k of each filter plate is 0.9 k; when the average speed v1 and the average speed v2 of the air outlet fan 16 are both greater than or equal to 50% of the corresponding full speed, the coefficient k of each filter plate is 1.1 k.
