Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments, it being understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
In order to solve the problem that the heat exchange effect of a unit is affected due to the fact that a method for cleaning a filter screen is mechanical and low in flexibility in the related art, an embodiment of the invention provides a method for reminding cleaning of the filter screen, as shown in fig. 1, the method is applied to a terminal side and comprises the following steps:
s101, determining the time required for the variation value of the outlet air temperature of the unit with the filter screen to reach a preset value;
step S102, when the time exceeds the preset time, sending a prompt instruction to the terminal to trigger the terminal to send out a reminding message;
the reminding information is used for reminding a user of cleaning the filter screen.
From this, the actual filth stifled condition of filter screen is known to the accessible judgement air-out temperature's situation of change, when confirming the filter screen needs to wash, reminds the user to wash again, compares with current scheme, has more the flexibility, and the accuracy is higher to improve heat transfer effect, reduced energy resource consumption.
In a possible implementation manner, the step S101 of determining the time required for the outlet air temperature variation value of the unit where the filter screen is located to reach the preset value includes: determining the time required by the air outlet temperature reduction value to reach a preset value when the unit is in a refrigeration mode; or determining the time required by the unit to reach the preset value of the outlet air temperature rise value in the heating mode. For example, the time required for the unit to be lowered by 5 degrees in the cooling mode or the time required for the unit to be raised by 5 degrees in the heating mode.
In a possible implementation manner, as shown in fig. 2, in step S102, when the time exceeds the preset time, sending a prompt instruction to the terminal to trigger the terminal to send the reminding information includes:
and S1021, when the ratio of the time to the preset time reaches a preset ratio, sending a prompt instruction to the terminal.
The preset time is the time required for the outlet air temperature change value to reach the preset value when the filter screen is not dirty and blocked. It can be understood that after the filter screen is used for a period of time, the filtering objects can be gathered on the surface of the filter screen, which affects the filtering effect and the ventilation effect of the filter screen, for example, when the unit is an air conditioner, the cooling and heating effect of the air conditioner can be affected, and the filter screen needs to be cleaned and replaced in time. In the embodiment of the invention, whether the filter screen needs to be cleaned or replaced can be determined according to the actual filth blockage degree of the filter screen, so that the heat exchange effect of the unit can be ensured, and the energy waste or the cost waste caused by frequent replacement can be avoided.
In a possible implementation manner, the unit may be an air conditioner, a fresh air system, or the like, and the unit is wirelessly connected (by way of WIFI or the like) to a server (which may be understood as a data center of a manufacturer). After the unit is started, the main controller of the unit can monitor the running state, the environmental information and the like of the unit and send the running state, the environmental information and the like of the unit to the server in a wireless communication mode. The server can analyze the related information to determine the current dirty and blocked condition of the unit filter network. Wherein, the relevant information is: the air outlet temperature variation value of the unit, the ambient temperature, the pipeline water inlet temperature, the wind shield running condition information and the like. After receiving the relevant information, the server firstly searches the stored data for preset time. The preset time is the time required for the outlet air temperature change value to reach the preset value when the filter screen is not dirty and blocked. It should be noted that, in the comparison process, the ambient temperature and the pipeline inlet water temperature are consistent, that is, are invariant. The server needs to determine the current pipeline water inlet temperature and the current environment temperature of the unit, and search the database for the preset time corresponding to the current pipeline water inlet temperature and the current environment temperature. And, the preset time is used as a reference value. For example, the following steps are carried out: assuming that the inlet water temperature of the pipeline is 15 ℃ and the ambient temperature is 35 ℃, the time required by the unit to ensure 24-degree refrigeration operation is T1; if the ambient temperature is 30 degrees and the remaining conditions are not changed, it is obvious that the temperature is decreased from 30 degrees to 24 degrees more quickly, and the required time is less than T1, i.e. the predetermined time is less than T1. If the temperature of the inlet water of the pipeline is changed to 12 degrees, and other conditions are not changed, the cooling water with the temperature of 12 degrees has stronger refrigerating capacity than the cooling water with the temperature of 15 degrees, and the required time is less than T1, namely the preset time is less than T1. Therefore, when the server determines the preset time, the preset time needs to be determined according to the current ambient temperature of the unit and the water inlet temperature of the pipeline.
It should be noted that the preset time may change with the change of any one of the ambient temperature and the inlet water temperature of the pipeline. Similarly, the time required for the outlet air temperature variation value to reach the preset value also varies. But the ratio of the two may be approximately fixed. The ratio determined over a number of experiments was approximately 1.2 times. Therefore, fig. 2 is a preferred embodiment of sending the prompt instruction to the terminal when the ratio of the time to the preset time reaches the preset ratio.
It is understood that the filtering object of the filtering net can be common air pollutant, or oil smoke, dust, mould, formaldehyde, etc. If the locations of the units are different, the air environments are different (for example, the pollution degrees of the two places of Beijing and Shenzhen are different), and the filth degrees of the filter screens are different, the interval time of sending the instructions to the terminals matched with the units in different regions by the factory server (data processing center) is different.
In a possible implementation manner, before determining the time required for the outlet air temperature variation value of the unit where the filter screen is located to reach the preset value in step S101, the method further includes: and determining that the running time of the unit reaches the preset time.
When the newly installed unit is not used, the filter screen is new and is not dirty and blocked, and dust and the like can be adsorbed after the unit is operated for a period of time, so that dirty and blocked are caused. In order to save energy, in a preferred implementation manner, step S101 may be executed after the operation duration of the unit reaches a preset duration, so as to better meet the actual operation condition of the unit and save energy.
In one possible implementation manner, the preset duration is an average weighted value of the durations of the operation of the fans of the unit under different wind gears. And when the wind gear of the fan is divided into a high wind gear, a medium wind gear and a low wind gear, the preset time is determined by the following formula:
T1＝k1*x+k2*y+k3*z；
wherein, T1 is the preset duration, x, y, z are the duration that the fan operated under low wind gear, medium wind gear, high wind gear respectively, k1, k2, k3 are the weighting coefficient of low wind gear, medium wind gear, high wind gear respectively, wherein, k1< k2< k 3.
The server can obtain and record the running time of the unit in each wind gear, the unit is provided with three-gear fans, the low wind gear runs for x hours, the middle wind gear runs for y hours, and the high wind gear runs for Z hours. Then k1, k2 and k3 can be determined according to the heat exchange capacity of each windshield. The time for different wind gears is referred to the following formula: t1 ═ k1 × x + k2 × y + k3 × z, and a weighting operation was performed. When the unit running time T1 exceeds K hours (preset time), step S101 is executed again. Determining the current environmental temperature section interval of the unit, for example: [29, 32], determining the required time L when the temperature is decreased by m degrees (the change value of the outlet air temperature), and sending an instruction to the terminal when the ratio of the L to the normal operation time (the preset time) reaches a preset ratio so that the terminal pushes a prompt for cleaning the filter screen to a user through the APP.
It should be noted that when the fan is operated at a low wind speed and the dust adsorption capacity is poor at a high wind speed, k1< k2< k 3. The ambient temperature interval may also be the current ambient temperature.
In a possible implementation manner, as shown in fig. 3, in step S102, when the time exceeds the preset time, a prompt instruction is sent to the terminal to trigger the terminal to send out the reminding information, and the method further includes:
step S103, setting time length at intervals and sending a prompt instruction to the terminal;
wherein the set duration is adjusted according to the time interval; the time interval is the time required between the time when the unit is started and the time when the prompting instruction is sent to the terminal for the first time.
Wherein the set duration is determined by the following formula:
setting the duration as the time interval kn; where n is the number of times the cue command is sent, n is a positive integer, and when n is 1, kn is a coefficient, and kn decreases as n increases.
In a possible implementation manner, before determining the time required for the outlet air temperature variation value of the unit where the filter screen is located to reach the preset value in step S101, the method further includes: and detecting the change value of the outlet air temperature in real time.
The server can determine the time of cleaning the filter screen next time, and when the current time is the time of cleaning the filter screen next time, the server sends an instruction to the terminal, so that the terminal sends prompt information through the APP. The terminal can also store the correlation coefficient in advance, automatically determine the time for cleaning the filter screen next time, and send prompt information to the user when the time is up.
The time for cleaning the filter screen for the next time can be determined by big data analysis again, and the coefficient kn can also be determined by a plurality of experiments, it can be understood that the longer the service time of related loads (such as a fan and the filter screen) in the unit is, the more serious the contamination degree is, even if the load is cleaned, the non-return to the factory state is possible, and correspondingly, the interval between the second cleaning time and the first cleaning time can be longer than the interval between the third cleaning time and the second cleaning time. The coefficient kn decreases as the value of n increases. Therefore, the cleaning time is more intelligent, the heat exchange effect of the unit is further improved, and the energy waste is reduced.
Fig. 4 shows a filter screen cleaning reminding method, which is applied to a terminal side, and includes:
step S401, receiving a prompt instruction sent by a server;
step S402, sending out reminding information to remind a user to clean the filter screen;
step S403, determining a time interval;
the time interval is the time required between the start of the unit where the filter screen is located and the first time of receiving the prompt instruction;
and step S404, calculating the set time length according to the time interval.
In one possible implementation manner, after sending the reminding message, the method further includes: and sending out reminding information at intervals of set time length. After sending out the reminding information, the method further comprises the following steps: receiving an instruction input by a user; and clearing the reminding record according to the instruction.
It should be noted that, after the user processes the filter screen, the user can enter the corresponding menu to clear the reminder to complete the operation, and meanwhile, the terminal can record the number of times of reminding, and the next reminding time is multiplied by the coefficient on the basis of the preset time, so that the server is not required to send an instruction to the terminal every time the filter screen needs to be cleaned, and the operation is simple and avoids data redundancy.

step S501, starting and operating a unit;
step S502, the accumulated running time of the unit fans is greater than or equal to K hours; if yes, executing step S503, if no, ending the process;
