Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1, fig. 1 is a schematic flow chart of an intelligent control method for a fresh air machine according to an embodiment of the present invention.
The embodiment of the invention provides an intelligent control method of a fresh air machine, which comprises the following steps:
s101, acquiring first indoor air quality data of a space where a fresh air fan is located, and calculating a first indoor air quality index according to the first indoor air quality data;
specifically, the first indoor air quality data of the space where the new fan is located can be obtained by detecting the air quality detection device, wherein the first indoor air quality data refers to the indoor air quality data corresponding to the new fan when the new fan works. This air quality detection device can set up indoor, also can set up on new fan, and the concentration that mainly used detected six indexs of PM2.5, PM10, nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone is as first indoor air quality data. The first indoor air quality index may be calculated according to the concentrations of the six indexes, and may specifically be calculated by formula (1):
among them, IAQIpThe index is the sub index of each detection index; cPIs the mass concentration value of the detection index; BP (Back propagation) ofHiIs CPHigh values of similar contaminant concentration limits; BP (Back propagation) ofLoIs and CPLow values of similar contaminant concentration limits; IAQIHiIs a reaction with BPHiA corresponding air mass fraction index; IAQILoIs a reaction with BPLoCorresponding air mass fraction index. After calculating the sub-indexes of all detection indexes, taking AQI as max { IAQIPAs the final air quality index.
S102, comparing the first indoor air quality index with an outdoor air quality index, and starting the fresh air machine to operate if the first indoor air quality index is larger than the outdoor air quality index.
The outdoor air quality index can be directly obtained from a server through the internet, and the air quality index of each place can be regularly updated on the internet, so that the corresponding air quality index can be directly obtained from the internet as the outdoor air quality index based on the geographical position of the fresh air machine; in addition, outdoor air quality data detected by an outdoor air quality detector in the fresh air fan can be obtained, and an outdoor air quality index can be calculated according to the outdoor air quality data. It can be understood that, in the embodiment of the present invention, an air quality detector may be installed on a portion of the fresh air blower located outside the wall body (i.e., a portion of the fresh air blower located outdoors), so as to detect outdoor air quality data, and after the outdoor air quality data is obtained, a corresponding outdoor air quality index may be obtained through calculation in formula (1).
It can be understood that the larger the air quality index is, the larger the representative pollutant concentration is, and the worse the air environment is, so after comparing the first indoor air quality index with the outdoor air quality index, if the first indoor air quality index is larger than the outdoor air quality index, that is, the representative pollutant concentration in the room is larger than the pollutant concentration in the outdoor, and the air environment is worse, at this time, the new fan is started to change the air indoors and outdoors, so as to purify the air environment in the room.
Referring to fig. 2, fig. 2 is a schematic flow chart of the operation of a new fan according to an embodiment of the present invention. After the new fan is powered on and started, the new fan starts to acquire indoor and outdoor air quality data, judges whether the indoor air quality is superior to the outdoor air quality or not according to the indoor and outdoor air quality data, and enters a standby mode and continuously acquires the indoor and outdoor air quality data if the indoor and outdoor air quality data are superior to the outdoor air quality; if not, the new fan starts to operate to perform indoor and outdoor ventilation until the indoor air quality is superior to the outdoor air quality.
For convenience of understanding, the intelligent control method of the fresh air machine provided by the embodiment of the invention will be described in detail below with reference to specific scenarios. For example, under indoor environment such as room, sitting room or kitchen, the user smokes under indoor environment and can lead to indoor PM2.5 concentration sharply increasing, the user can produce the oil smoke when cooking and lead to indoorly, can produce a large amount of carbon dioxide and nitrogen dioxide, all can make the indoor environment sudden change, if the user does not in time carry out ventilation this moment, indoor air quality will all be in relatively poor level in longer a period of time, lead to carrying out the air that the user of normal daily life activity inhales and contain a large amount of pollutants indoor, harm user's health. For another example, in an indoor environment such as an office, when the number of people accommodated in the office is large and the ventilation effect is poor (such as in a winter environment with doors and windows closed), along with the extension of the office time, office staff inside the office can generate a large amount of carbon dioxide during normal breathing, so that the concentration of carbon dioxide in the office is high overall, and if ventilation is not performed in time, the concentration of carbon dioxide in the office can be at a high level within a long period of time, so that the office staff can easily have symptoms such as dysphoria, stuffiness and difficulty in concentration. By implementing the fresh air machine control method, the indoor and outdoor air quality can be monitored and compared in real time or regularly, when the indoor air quality is different from the outdoor air quality, the fresh air machine is automatically started in time to change air, the air circulation is ensured, a good indoor air environment is created for a user, the starting process of the fresh air machine is full-automatic, manual operation of the user is not needed, and the fresh air machine is convenient and intelligent.
Because new fan self all can have filter equipment usually, can have certain purification and filtration effect to the air, when starting new fan and taking a breath, outdoor air can filter through the filter equipment on the new fan and purify the back reentrant indoor, and the air that actually enters into indoor is than outdoor original air quality and is higher. Therefore, when the indoor and outdoor air quality is considered to be compared, the air quality of the outdoor air filtered and purified by the filtering device can be compared with that of the indoor air, so that a better comparison result can be obtained. In an optional implementation manner, after the indoor air quality data of the space where the new fan is located is obtained, the outdoor air quality data of the space where the new fan is located can be obtained; calculating theoretical data of outdoor air quality after outdoor air passes through a filtering device of the fresh air fan according to the outdoor air quality data, and calculating a theoretical air quality index of the outdoor air according to the theoretical data; and comparing the indoor air quality index with the theoretical air quality index, and starting the fresh air machine to operate if the indoor air quality index is greater than the theoretical air quality index. The theoretical data of the outdoor air quality is calculated by combining the filtering efficiency of the filtering device on the fresh air fan and the outdoor air quality data, and is the theoretical data of the outdoor air purified by the filtering device.
Further, in consideration of the fact that the first indoor air quality index and the outdoor air quality index are compared with each other, the method may further include the following steps: and comparing the outdoor air quality index with a preset quality index value, and controlling the new fan to send an alarm signal if the outdoor air quality index is greater than the preset quality index value. It will be appreciated that after the outdoor air quality index is obtained, the outdoor air quality index may be compared with a preset quality index value, wherein the preset quality index value may be determined based on actual conditions. Referring to table 1, table 1 is an air quality criteria table:
TABLE 1
As can be seen from table 1, when the air quality index is greater than 200, the air grade is heavily polluted or above, and at this time, the filter element of the filtering device is greatly lost when the heavily polluted outdoor air is subjected to ventilation and filtration, and the actual ventilation efficiency is low. Therefore, when the preset quality index value is set to be 200 or more than 200, the fresh air fan can be prevented from being started continuously for ventilation under the condition of poor outdoor air quality, and at the moment, the fresh air fan can directly send out an alarm signal to remind a user of paying attention.
It can be understood that when a user installs new fans in a plurality of connected spaces (for example, a plurality of connected rooms) respectively, the new fans can form a set of complete new fan system, each new fan in the set of new fan system is reasonably configured according to the air environment of the space where the new fan is actually located, and outdoor air can be rapidly filtered and then introduced into a room, so that the overall air environment of the room is efficiently improved.
Specifically, in an implementation manner provided by the embodiment of the present invention, the method further includes: when a plurality of fresh air fans are in a state of waiting to operate at the same time, respectively acquiring second indoor air quality data of a space where each fresh air fan is located, and respectively calculating corresponding second indoor air quality indexes according to the second indoor air quality data; and comparing the second indoor air quality index with the outdoor air quality index, and if part of the second indoor air quality index is larger than the outdoor air quality index, starting a new fan corresponding to the part of the second indoor air quality index to operate.
The second indoor air quality data refers to indoor air quality data corresponding to each fresh air machine when the plurality of fresh air machines work in a cooperative manner. It can be understood that, since the space where each new fan is located is different, the second indoor air quality data obtained by detecting each new fan correspondingly is also different, for example, when the three new fans are respectively arranged in a bedroom, a living room and a kitchen, the air environments in the bedroom, the living room and the kitchen are different, and the second indoor air quality data obtained by detecting each new fan is also different, that is, each new fan has its corresponding second indoor air quality data. When only part of the new fans detect that the second indoor air quality data is larger than the outdoor air quality index, only the new fans of the part are started to ventilate, and other new fans are in a standby state.
In an implementation manner provided by the embodiment of the present invention, the method further includes: when a plurality of fresh air fans are in a state of waiting to operate at the same time, respectively acquiring second indoor air quality data of a space where each fresh air fan is located, and respectively calculating corresponding second indoor air quality indexes according to the second indoor air quality data; comparing the second indoor air quality index with the outdoor air quality index, if all the second indoor air quality indexes are greater than the outdoor air quality index, judging whether the second indoor air quality index is greater than a preset threshold value, starting a first fresh air fan and a second fresh air fan to operate, enabling the rotation speed of an exhaust fan of the first fresh air fan to be greater than that of an air supply fan, and enabling the rotation speed of an air supply fan of the second fresh air fan to be greater than that of the exhaust fan; and the second indoor air quality index corresponding to the first fresh air fan is greater than the preset threshold, and the second indoor air quality index corresponding to the second fresh air fan is less than or equal to the preset threshold. The preset threshold may be set according to specific indoor conditions, or all the second indoor air quality indexes may be sorted according to size, and a median of all the second indoor air quality indexes is used as the preset threshold. For example, if there are 5 new air blower devices in a room, and the second indoor air quality index corresponding to each new air blower is 20, 40, 70, 100 and 120, respectively, 70 is the median, the new air blower corresponding to the second indoor air quality index of 100 and 120 is defined as the first new air blower, and the new air blower corresponding to the second indoor air quality index of 20, 40 and 70 is defined as the second new air blower,
it can be understood that when the indoor air quality detected by all the fresh air fans is lower than the outdoor air quality, the space where all the fresh air fans are located needs to be ventilated with outdoor air. The fresh air machine provided by the embodiment of the invention is provided with two channels of air supply and air exhaust, so that the fresh air machine can respectively supply outdoor air into a room and discharge indoor air to the outside. Therefore, in the embodiment of the present invention, the air quality index corresponding to the space where each new blower is located is compared with the preset threshold, and the new blower whose air quality index is greater than the preset threshold is defined as the first new blower, and the rest are defined as the second new blower, that is, the air quality of the space where the first new blower is located is relatively poor, and the air quality of the space where the second new blower is located is relatively good. At the moment, the first fresh air fan and the second fresh air fan are controlled to operate, the first fresh air fan is controlled to operate in a working mode that air exhaust is main air supply and auxiliary air exhaust is auxiliary air supply, and the second fresh air fan is controlled to operate in a working mode that air supply is main air exhaust and auxiliary air exhaust. Simply, the first fresh air blower is controlled to mainly perform air exhaust work, and the second fresh air blower is controlled to mainly perform air supply work. Because the spaces where the first fresh air fan and the second fresh air fan are respectively located are in a mutually communicated state, namely, air flow can be carried out between the spaces where the first fresh air fan and the second fresh air fan are located, when the first fresh air fan exhausts indoor air and the second fresh air fan sends the outdoor air, the plurality of mutually communicated spaces generate air flow, and the air in the space where the second fresh air fan is located flows into the space where the first fresh air fan is located, so that an air field is formed. Due to the flowing effect of air in the wind field, an outdoor air source is continuously supplemented in the space where the second fresh air fan is located, air with better internal quality can quickly flow into the space where the first fresh air fan is located, air with poorer internal quality is quickly discharged to the outside, quick ventilation of the whole indoor environment can be realized, the indoor air environment can be quickly and efficiently improved, and the situation that the air quality at the position far away from the fresh air fan in each space cannot be improved later is avoided.
It can be understood that, under normal conditions, a plurality of spaces in which the fresh air fans are located are in a state of being communicated with each other, and after communication between some of the spaces and other spaces is blocked, the spaces are actually relatively closed spaces. For example, the bedroom is normally communicated with the living room, when the door of the bedroom is closed, the bedroom is not communicated with the living room, and the bedroom is in a closed state, so that a single closed space is formed. Therefore, in this case, it is necessary to exclude the space in the sealed state and to prevent the space from being a part of the spaces communicating with each other. That is, before comparing the second indoor air quality index with the outdoor air quality index, the method may further include: and respectively judging whether the spaces where the plurality of fresh air fans are located are in a closed state or not, and comparing a second indoor air quality index corresponding to the fresh air fan of which the space is in a non-closed state with the outdoor air quality index. In addition, the fresh air machine in the closed state is independently controlled according to the indoor and outdoor air quality comparison condition.
Specifically, the determining whether the space where the plurality of fresh air machines are located is in a closed state may include: respectively judging whether doors or windows used for communicating other spaces in the spaces where the plurality of fresh air fans are located are in a closed state, if so, defining the spaces where the fresh air fans are located as a closed state, and otherwise, defining the spaces where the fresh air fans are located as an unsealed state; the signal whether the door or the window is in the closed state is received from a sensor mounted on the door or the window. It can be understood that after the sensor is installed on the door or window for communicating with other spaces in each space, whether the corresponding door or window is closed or not can be detected in real time, and if the door or window is closed, the space can be considered not to be communicated with other spaces but to be in a closed state, and the stand-alone control program is executed. It should be noted that the door or window in the embodiments of the present invention is used for communication between a plurality of indoor spaces, not for communication between the indoor space and the outdoor space.
Referring to fig. 3, fig. 3 is a schematic installation diagram of a fresh air blower according to an embodiment of the present invention. The figure comprises three rooms, namely a room 1, a room 2 and a room 3, wherein a door communicated between the room 1 and the room 2 is closed, the room 1 is in a relatively closed state, and the room 2 and the room 3 are in a communicated state. When the new air blower system operates, the new air blower 1 in the room 1 is independently controlled to operate according to the comparison condition of the air quality in the room 1 and the outdoor air quality. The new air blower 2 in the room 2 and the new air blower 3 in the room 3 form a new air blower system, and if the new air blower 2 and the new air blower 3 respectively detect that the air quality in the room 2 and the air quality in the room 3 are both lower than that of outdoor air and the air quality in the room 2 is higher than that of the room 3, at the moment, the new air blower 3 is controlled to mainly supply air as an auxiliary air supply, and the new air blower 2 is controlled to mainly supply air as an auxiliary air discharge, as shown by arrow directions in fig. 3, outdoor air flows into the room 2, air in the room 2 flows into the room 3, air in the room 3 is discharged out of a room, and air flows to form a new air field, so that the circulation updating of the air is.
For convenience, the method for controlling the whole house circulation of the fresh air machine according to the embodiment of the present invention will be described in detail below with reference to fig. 4. Fig. 4 is a schematic view of a whole-house circulation control process of a fresh air machine according to an embodiment of the present invention. Firstly, after the new fans are started, whether the space where each new fan is located is closed or not is judged, and if the space where each new fan is located is a closed space, single-room circulation control is executed on each new fan. Specifically, the single-room circulation control process is as follows: acquiring air quality data and outdoor air quality data in the closed space, judging whether the air quality in the closed space is superior to the outdoor air quality, and if so, controlling the fresh air fan to enter a standby mode and continuously acquiring indoor and outdoor air quality data; if not, the fresh air machine is controlled to start to operate, and indoor and outdoor ventilation is carried out until the air quality in the closed space is superior to the outdoor air quality.
If the space where the new fans are located is not a closed space, controlling each new fan to obtain indoor and outdoor air quality data of the space where each new fan is located, then judging whether the air quality in each space is superior to the outdoor air quality, and if the indoor air quality is superior to the outdoor air quality, outputting a signal 1 by the new fan correspondingly; if the outdoor air quality is better than the indoor air quality, the new fan correspondingly outputs a signal 0, and then all signal output values are summed to obtain a specific value X; and finally, judging the relation between the numerical value X and the total number N of the new fans:
if X is equal to N, the whole fresh air fan is in standby;
if X is more than 0 and less than N, the fresh air fan with the indoor air quality better than the outdoor air quality is standby, and other fresh air fans work;
if X is 0, sequencing the indoor air quality of each fresh air fan, and then judging whether the spatial air quality rank of each fresh air fan is lower than the median of the indoor air quality, wherein the fresh air fans lower than the median mainly exhaust air and supplementarily supply air; the fresh air fans not lower than the median mainly supply air and assist in exhaust air, so that one or more fresh air fields are formed. Some time after these procedures, all the equipment returns to the original state again, starting a new cycle.
