Description

Technical Field [0001] The present invention relates to an indoor / outdoor remote fine dust measuring device, a fine dust monitoring system, and a measuring and monitoring method using a communication module,

The present invention relates to an indoor / outdoor remote fine dust measuring device, a fine dust monitoring system, and a measuring and monitoring method using a communication module with an adapter. More particularly, the present invention relates to a system that can connect an Arduino fine dust sensor and a Bluetooth module, which is a control board using an open source circuit, to detect fine dusts in outdoor and indoor areas from a remote location in real time, .

Fine dust is an environmental issue that is very dangerous and must be resolved to the extent that it is nicknamed the "murderer of silence."

It is reported that about 120,000 people per year die from dust and harmful harmful substances such as fine dust, which is the origin of fine dust. Fine dust is a particle that is about one - tenth of the diameter of a hair (50 ~ 70 ㎛). It flows lightly with the airflow to the extent that it does not hit the wall, and it has a very high probability of digging nose, mouth and body parts.

Particularly, entering the brain can damage the brain cells and cause stroke or dementia. When they enter the eye, they can cause irritation or irritation to the eyeballs. If you inhale through the nose, the blood passes through the alveoli, and the blood puffs into the pores, causing inflammation of the skin. When you enter the lungs, the cough or asthma exacerbates, and the heart causes calcium metabolic abnormalities, leading to arrhythmia. In particular, if pregnant women do not have smooth blood circulation in the placenta, the fetus may become undernourished and the risk of brain damage to the fetus may be increased.

Recent studies on the acute effects of fine dust have been reported that the daily mortality increases by 2 ~ 3% when the fine dust concentration is increased by 100 ㎍ / ㎥. In particular, it is estimated that the number of acute deaths due to fine dust in Seoul is estimated to be about 1053 per year, which is about 8% of the total deaths, especially in respiratory and cardiovascular diseases.

The bigger problem is the fact that various activities such as climbing, jogging, hiking, etc. are increasing regardless of the time of day, because the public interest in health has been increasing recently, Activity can be a cause of serious diseases and it is becoming a social problem.

For this purpose, broadcasters provide information about fine dusts to viewers through weather forecasts or regular news hours. However, in such a case, it is practically difficult to obtain such information for a person who is out of the room where the broadcasting can be listened to, or is in a position where it is difficult for the warning broadcasting to reach, so that the concentration of fine dust in the atmosphere may exceed the reference value There is a problem that proper coping or evacuation can not be performed.

The notification unit 16 may be configured to transmit a notification signal by using a warning sound, a voice, or a visual display method when the fine dust concentration measured in real time exceeds an appropriate fine dust concentration value.

In the fine dust measuring method according to an embodiment of the present invention using the indoor / outdoor remote fine dust measuring device 10 to which the communication module 13 is applied, first, the fine dust measuring device 10 mentioned above is attached to / To be installed in at least one specific place.

Then, the fine dust sensor 12 provided on the substrate 11 based on the adonyne measures the fine dust concentration in real time. The fine dust concentration measured in real time by the fine dust sensor 12 is transmitted to the user terminal 20 set through the communication module 13. [ Accordingly, the user can check the fine dust concentration at a specific place in real time through the user terminal 20. [

Hereinafter, the configuration, function, and monitoring method of the indoor / outdoor remote fine dust monitoring system 100 to which the communication module 13 is applied according to an embodiment of the present invention will be described. FIG. 2 is a block diagram of an indoor / outdoor remote fine dust monitoring system 100 to which the communication module 13 is connected according to an embodiment of the present invention. 3 is a block diagram of a remote fine dust monitoring application installed in a user terminal 20 according to an embodiment of the present invention.

The indoor / outdoor remote fine dust monitoring system 100 to which the communication module 13 is applied according to an embodiment of the present invention includes the configuration of the fine dust measuring device 10 described above.

That is, in the indoor / outdoor remote fine dust monitoring system 100 to which the communication module 13 is applied according to the embodiment of the present invention, the fine dust measuring device 10 is installed in each of at least one specific place. Each of the at least one user terminals 20 equipped with the remote fine dust monitoring application receives the real time fine dust concentration measured by the fine dust meter 10.

When the user terminal 20 is set to execute the remote fine dust monitoring application, it can be connected to each of the fine dust measuring devices 10 installed at specific places through the communication module 13. It is possible to adjust the number of fine dust measuring devices 10 to be connected by Bluetooth according to the setting of the user.

<Experimental data>

Hereinafter, the results of the experimental example of the present invention will be described. 4 is a block diagram of the fine dust measuring device 10 used in the experimental example of the present invention.

FIGS. 5A, 5B and 5C show a comparison of the concentrations of outdoor fine dusts between the Korea Environmental Protection Agency and the Arundinometry Measuring Instrument of the present invention.

5A, the dust concentration value measured at 6:00 am on the roof was 50 μg / m 3 by the Arduino fine dust meter, and after that, the concentration value was slightly decreased And at the time of 12 o'clock, it was measured as 41 ㎍ / ㎥. The concentration of ultrafine dust provided by the Korea Environmental Protection Corporation was measured at 55 ㎍ / ㎥ at 6 am and gradually decreased at 37 ㎍ / ㎥ at 12 pm.

Next, in the concentration comparative graph of May 28 shown in FIG. 5B, the fine dust concentration value of the Arduino fine dust measuring device at 6 am was measured as 48 / / m 3, and gradually decreased to 34 ㎍ / M3. &Lt; / RTI &gt; The dust concentration value provided by the Korea Environment & Resources Corporation was somewhat higher at 53 ㎍ / ㎥ at 6 am and decreased sharply from 11 ‰ to 25 ㎍ / ㎥ at 12.

Finally, in the concentration comparison graph on May 29 shown in FIG. 5C, the concentration value of the Arundinomile dust meter at 6:00 am was measured as 39 μg / m 3, and thereafter repeatedly increased and decreased, As shown in Fig. The dust concentration value provided by the Korea Environment & Resources Corporation was measured as 32 ㎍ / ㎥ at 6 am. Unlike the other experiments, the dust concentration value was measured at 39 ㎍ / ㎥ rather than at 12.

Since the Arundinometer of the present invention measures the amount of dust that comes in real time at intervals of 5 seconds, it uses an authorized device that has a wide range of measured values and calls for tens of thousands of won, It is true that the accuracy is lower than the fine dust level of Korea Environment Corporation. However, three experiments show that the measured values of the Arundinometer and the KNDC show similar trends and levels. Accordingly, it was determined that the Arduino-based fine dust measuring apparatus according to the present invention exhibits a level of contamination of ultrafine dust due to human activities and an accuracy enough to measure the trend of the contamination level. Therefore, it can be seen that the present invention can be fully utilized in real life.

FIGS. 6A and 6B show a comparison between the indoor fine dust concentration and the fine dust concentration after using the vacuum cleaner. In the graph of the indoor fine dust concentration on May 29 shown in FIG. 6A, the dust concentration is usually measured at 35 to 40 μg / m 3, and no difference is observed. On the other hand, the concentration of fine dust increases slightly when the vacuum cleaner is operated. Particularly, the concentration of fine dust increases greatly in the elapsed time of about 3 minutes, which is considered to be caused by the generation of dust when the cleaner is operated for the first time. The time gradually decreases with time, and after 9 minutes, it gradually converges to the normal fine dust concentration value.

The indoor fine dust concentration graph on June 3 shown in FIG. 6B also shows a similar shape. The usual dust concentration shows a slight change based on 40 ㎍ / ㎥. When the vacuum cleaner was operated, the fine dust concentration was measured as 72 ㎍ / ㎥ in about 3 minutes and gradually decreased to 37 / / ㎥ in 15 minutes and it was almost similar to the normal dust concentration. Two experiments show that the fine dust generated when operating the cleaner occurs most immediately after the operation of the vacuum cleaner, which is a bad value due to the 'fine dust density criterion'. Therefore, if you start to operate the vacuum cleaner, it is better to clean the vacuum cleaner as much as possible. It is advisable to clean the vacuum cleaner immediately after cleaning. Also, taking into account the fact that the position of measuring dust is 40cm ~ 60cm from the ground, caution is needed because crawling babies, tiny infants and preschoolers will be affected by fine dust when cleaning. Therefore, it was considered that it would be better to clean at the time when most people do not reside.

7 shows a comparison of effective distances of bluetooth transmission and reception of the Arduino dust meter. This experiment was conducted in a home and school room, and the Bluetooth signal was confirmed as a smartphone application every 3 seconds. After moving for 15 seconds, we checked the normal operation and moved again. We divided into 3 types and experimented 15 times per experiment.

Experiment 1 was measured from a distance of 16m from a living room without a wall and moved 1m at success. In Experiment 2, a module was placed in a room and measured from a distance of 12m with the door closed. Respectively. Experiment 3 was carried out with the door closed and the living room door closed. In the case of the living room without special walls or obstacles in Experiment 1, the pairing was well maintained and the average distance was measured to be 19 m or less. Experiment 2 was carried out with a fine dust meter and a module in the room, with the door closed. The average distance was measured to be 14 m or less. Experiment 3 was performed when the door was closed and the living room door was closed, Distance. Based on the above experiment, it was possible to check the minute dust measurement, which is transmitted in real time to the living room or other room in the house, by using the mobile phone after leaving the Arduino Dust Analyzer in the room. In the case of a housewife who spent a long time at home, Can also be used to obtain measurements if there are babies or children in other rooms in the house. If there is no obstacle, that is to say, in the case of an ordinary home with a visit, if the dust meter is in the room and the measurer is in the living room, a sufficient distance of 19 meters is considered. If there is one obstacle while the visit is closed, the communication situation may be cut off due to the effective distance of 14m. When measuring at home, it is better to measure while keeping a visit open to obtain a smooth value. However, if it is necessary to close it, it is preferable to place the mobile phone at a closer distance.

8A, the fine dust concentration at the time of the general meat cooking was gradually increased while cooking, and it increased sharply at the passage from 6 minutes to 8 minutes, and the concentration of the fine dust Was the highest at 84 ㎍ / ㎥. On the other hand, when the meat was cooked after operating the range hood, there was almost no change in the fine dust measurement value. When the range hood was turned on, the concentration of fine dust was measured at 45 ㎍ / ㎥ over 8 minutes, which is very different from the previous experiment.

As shown in FIG. 8B, the concentration of fine dust in the fish meat gradually increased as in the case of meat, and the maximum value was measured as 88 μg / m 3 at 10 minutes. When cooking fish after operating the range hood, there was no significant difference in the fine dust measurement values as in the case of cooking meat. When the hood was operated, the fine dust measurement value was about 41 μg / ㎥ for about 10 minutes, and the difference in fine dust concentration about 47 μg / ㎥ was found.

 The results obtained from the previous two experiments show that when cooking indoors, it is possible to reduce the concentration of fine dust by up to 50% or more when the cooking hood is operated and cooked. In this experiment, we selected baking method that can generate a lot of fine dust when cooking food. After 4 minutes from starting cooking meat and fish, all of them exceeded PM2.5 limit of 50 ㎍ / ㎥ Respectively. However, as demonstrated in the experiment, by operating the cooking hood during the cooking process, the fine dust generated during cooking can be sufficiently reduced and the generation of fine dust can be significantly reduced even when cooking or boiling instead of cooking the food. Therefore, it is necessary to cook in a state where the cooking hood or the ventilator is activated when cooking in the room, and it is important to ventilate the indoor fine dust to circulate with the outside air after cooking.

It should be noted that the above-described apparatus and method are not limited to the configurations and methods of the embodiments described above, but the embodiments may be modified so that all or some of the embodiments are selectively combined .
