Description

Air quality control system and its operating method

The invention relates to an air quality control system and its operating method, in particular to an automatic air quality adjustment module, and at the same time to formulate a conflict resolution mechanism in the control process to improve the air quality of the environment.

With the rising awareness of environmental protection and people's emphasis on health issues, the issue of air quality is gradually fermenting in society. Existing home environment systems, for indoor and outdoor air quality control methods are nothing more than exhaust fans or airtight windows. However, under the condition that the air quality is not extremely poor, it is difficult for the average person's five senses to judge whether the current indoor air quality is harmful to the human body.

The rapid development of China in recent years has caused haze damage, which has made Taiwan begin to pay attention to the hazards of haze. In addition, the aerosols generated by the western Taiwan industrial zone and thermal power plants are difficult to diffuse because of the relationship between the terrain and the wind direction. Therefore, in the autumn and winter seasons where the northeast monsoon is popular, aerosols are often the main cause of poor air quality, and the particle size is less than 2.5 Micron fine suspended particles are harmful to human health. At present, many popular pathological studies have shown that the health effects of PM2.5 include: premature death, bronchitis, asthma, cardiovascular disease, lung cancer, etc., whether long-term or short-term Exposure to air pollutants can increase the risk of respiratory diseases and death. Therefore, the Taiwan Environmental Protection Agency participated in the British Air Quality Index (DAQI) fine airborne particulate (PM2.5) early warning concentration classification, and the index was divided into 10 levels and the color warning was used to determine whether the air quality reached A basis for the degree of harmfulness is that the high concentration of PM2.5 reaching the index level 6 may have caused harm to the human body. In addition, the moisture, temperature, etc. contained in the air are also one of the factors that affect human health.

Therefore, it is very important how to effectively detect whether the ambient air quality is good, and further provide air quality information and immediately improve the air quality to avoid harm to the human body. Generally speaking, air purifiers or filters are mostly used to improve indoor air quality, but even if there are air purifiers or filters, their opening and closing need to be manually determined by human judgment. It is difficult to judge whether the current indoor air quality is harmful to the human body. It is manually opened when it is uncomfortable. Not only can it not effectively prevent suspended particles in the air in a timely manner, nor can it be opened 24 hours a day, and in addition to lowering In addition to the life of the equipment, it also causes a waste of energy and money.

The at least one air quality adjustment module 400 is a window opening device, an air purifier, an air filter, a positive and negative pressure regulator, an air conditioner, or a combination thereof.

The specific embodiments of the present invention will be further described below.

The outdoor environment sensing module 100 and the indoor sensing module 200 of this embodiment both include at least one suspended particle sensor 110, 210 and at least one temperature sensor 120, 220. The air quality adjustment module of this embodiment Group 500 includes window opening devices, air cleaners and air conditioners.

表1、系統感測溫度規則表 First, the temperature sensor 220 of the indoor sensing module 200 detects the temperature of the indoor environment (that is, indoor air quality information), and transmits it to the system server 300 through the interface control module 240. The comparison unit 312 of the system server 300 compares the indoor air quality information according to the air quality threshold information; wherein, the air quality threshold information here refers to a temperature lower than 20 degrees Celsius or higher than 26 degrees Celsius as the temperature The threshold is too high or too low. Table 1 below is the rule table formulated by the system server 300 for the indoor temperature. In the rule table, 0 is used to indicate that the temperature is higher than 26 degrees Celsius, 1 is used to indicate the temperature is between 20-26 degrees Celsius, and 2 is used to indicate the temperature. Below 20℃.

Table 1. System sensing temperature rule table

Under this condition, if the comparison result of the system server 300 is rule 1 (that is, the indoor ambient temperature is too high), the system server 300 will control the switch of the air quality adjustment module 400 through the third interface control module 440 , Here is to start the switch of the air conditioner and adjust to cool air, and close the window opening device. If the comparison result of the system server 300 is rule 1 (that is, the indoor ambient temperature is moderate), the system server 300 will turn off the switch of the air conditioner through the third interface control module 440 and turn on the window opening device. If the comparison result of the system server 300 is rule 3 (that is, the indoor ambient temperature is too low), the system server 300 will turn on the switch of the air conditioner through the third interface control module 440 and adjust to heating, and close the window Device (the above is the first comparison result).

表2、系統感測懸浮微粒濃度規則表 On the other hand, if the indoor and outdoor sensing modules 100 and 200 of the system also have other types of sensors, conflicts may occur. Taking this embodiment as an example, the indoor and outdoor sensing modules 100, 200 may also have at least one suspended particle sensor 110, 210 to detect the suspended particle concentration of the indoor and outdoor environment (ie, indoor and outdoor air quality information ), and sent to the system server 300 through the interface control modules 140, 240. The comparison unit 312 of the system server 300 compares the indoor air quality information according to the air quality threshold information; wherein, the air quality threshold information here is the lower limit PM2.5 concentration of the air quality index level 6 48 μg/ m ^{3 is} used as the threshold of air quality. Table 2 below is the rule table formulated by the system server 300 for indoor and outdoor suspended particle concentration, where 1 is used in the rule table to indicate that the suspended particle concentration is lower than the threshold value, which means that the air quality is good; 0 is that the suspended particle concentration is higher than the threshold value Value, air quality is bad.

Table 2. Rule table of system sensing suspended particle concentration

Under this condition, if the comparison result of the system server 300 is rule 1 (that is, both indoor and outdoor air quality is good), the system server 300 will control the air quality adjustment module 400 through the third interface control module 440 Switch, here is the switch to activate the window opening device, and turn off the air purifier. If the comparison result of the system server 300 is rule 2 (that is, the indoor air quality is good and the outdoor air quality is bad), the system server 300 will turn off the switch of the window opening device through the third interface control module 440 and turn off the air purification machine. If the comparison result of the system server 300 is rule 3 (that is, the indoor air quality is bad and the outdoor air quality is good), the system server 300 will control the module 440 group through the third interface to open the switch of the window opening device and turn on the air purification machine. If the comparison result of the system server 300 is rule 4 (that is, both indoor and outdoor air quality is bad), the system server 300 will turn off the switch of the window opening device through the third interface control module 440, and turn on the air purifier ( The above is the second comparison result).

It is worth noting that due to the different types of sensors included in the indoor and outdoor sensor modules 100, 200 (temperature sensor and suspended particle sensor), it may cause the system server 300 to control the air quality adjustment module 400 The switch is in conflict and cannot function properly. Taking the above embodiment as an example, the conflict occurs because the system server 300 controls the conflict of the window opening device. In other words, when the system server 300 determines that the window opening device needs to be “opened” due to the temperature sensor 220, it also causes The suspended particle sensor 110, 210 determines that the window opening device needs to be “closed”; and when the system server determines that the window opening device needs to be “closed” due to the temperature sensor 220, but also determines that the suspended particle sensor 110, 210 If you need to "open" the window opening device, there will be conflicts and the conflict handling unit needs to provide a solution.

表3、衝突規則表（一） The condition that the system server 300 needs to "open" the window opening device due to the determination of the concentration of suspended particles is when the indoor suspended particle concentration is high and the outdoor suspended particle concentration is low, and when the indoor suspended particle concentration is low and the outdoor suspended particle concentration is low. At the same time, the condition for the "open" window opening device due to temperature judgment is: when the indoor temperature is too high or too low. By synthesizing these conditions, the conflict rule table (1) in Table 3 below can be obtained.

Table 3. Table of conflict rules (1)

表4、衝突規則表（二） In addition, the system server 300 needs to "close" the window opening device due to the determination of the concentration of suspended particles: when the indoor suspended particle concentration is low and the outdoor suspended particle concentration is high, and when the indoor suspended particle concentration is high and the outdoor suspended particle concentration is high . At the same time, the condition for the "open" window opening device due to temperature judgment is: when the indoor temperature is moderate. By synthesizing these conditions, the conflict rule table (2) in Table 4 below can be obtained.

Table 4. Table of conflict rules (2)

The above two conflict rule tables are the conditions under which the conflict condition will occur. After knowing the timing of the conflict condition, the conflict processing unit 312 is required to provide a solution.

The conflict processing unit 312 of this embodiment includes the following three solutions: Setting the priority order, According to the longest match principle, and Adding new rules, In this embodiment, the priority setting is mainly used as the main conflict handling method.

The principle of setting the priority ranking is that the conflict processing unit 312 of the system server 300 will decide which air quality adjustment module 400 determines to have priority. In this way, when conflict occurs, the air quality adjustment with higher priority will be adjusted. The module 400 takes control. First of all, the conflict processing unit 312 will give priority to the conditions where the user has immediate hazards, such as the high carbon monoxide concentration or the occurrence of fire, outdoor storms and other conditions, which must be ranked first. For other conditions that are not the highest priority and have no immediate harm to humans, a third-party air quality adjustment module can be added to solve the conflict situation; for example, the "full heat exchanger" can be added At the same time, the problem of the need to close the window opening device, turn on the air conditioner to lower the temperature, and introduce fresh air to solve the problem is solved. Therefore, if the window opening device needs to be closed and fresh air needs to be introduced at the same time, the system server 300 should activate the full heat exchanger. Furthermore, when a third-party air quality adjustment module is used, priority can also be set for the order in which the third-party air quality adjustment module is activated. Taking this embodiment as an example, an abnormally suspended particulate concentration can be activated The window device introduces natural ventilation, or starts the air purifier to solve, and the temperature abnormality (the temperature is too high or too low) can only be solved by the air conditioner, so the temperature abnormality that lacks the solution means will be set and the conditions that are given priority are set.

In addition, when using priority to resolve conflicts, it is also necessary to consider the difficulty of environmental control. For example, in this embodiment, temperature belongs to a method that lacks control and has a higher priority; therefore, the adjustment of system server 300 The sequence is to control the temperature first, and then control the concentration of suspended particles. After deciding the order of priority, we then deal with conflicts. For example, when the air conditioner needs to be turned on, the window opening device will be closed first, and then the air purifier will be turned on again to control the concentration of suspended particles.

Regarding the setting of the air quality threshold information in this case, the threshold values are relatively clear (the lower limit of the air quality index level 6 PM2.5 concentration 48μg/m ^{3 is} used as the threshold value of air quality, or the temperature is lower than 20 degrees Celsius or higher than 26 degrees Celsius as the threshold of excessive temperature or too low); however, if the perception conditions involve the user's experience, the definition of the threshold will become blurred, such as the temperature of different users. Feelings like cold, moderate or overheating are also different. In addition, the operating conditions of the air quality adjustment module set in this case are relatively simple, only the on/off state setting; however, the windows have different opening and closing angles from 0 to 90 degrees, and the air cleaner and air conditioner are actually There will also be strong, medium or weak modes with different wind speeds, or different concentration treatment and temperature setting modes can be selected. The above-mentioned limitations beyond the binary conditions require other algorithms to solve them, such as the use of "fuzzy logic" or "neuro-fuzzy".

As can be seen from the above, the present invention can effectively use real-time or non-real-time air quality information provided by the outdoor environment sensing module and the indoor environment sensing module, directly calculate through the system server and determine whether to enable one or more air quality adjustments The module controls the air quality of the environment without manual or control. It also allows the user to know the current detected air quality status through a display device such as a mobile phone no matter where it is, and feed back the air quality data. . In addition, the system server of the present invention can also be prioritized according to the priority set by the conflict processing unit to solve the conflicts caused by the system server due to different sensing conditions when controlling the air quality adjustment module to maintain the cost. The operation of the invented air quality control system.

However, the above are only preferred embodiments of the present invention, and the scope of implementation of the present invention cannot be limited by this, that is, simple changes and modifications made according to the patent application scope and description of the present invention are still within the present invention.
