Description

Smart artificial intelligence environmental monitoring and control device {SMART ENVIRONMENTAL MONITORING AND CONTROL DEVICE BASED ON ARTIFICIAL INTELLIGENCE}

The present invention relates to environment measurement and monitoring technology, and more particularly, to an environment monitoring and control device configured indoors to adapt and set various functions to an installation environment and to perform it.

In recent years, as industrialization is accelerated and residential life is urbanized, various home appliances are used at home or office, resulting in frequent safety accidents, and indoor air is gradually polluted.

Accordingly, users are concerned about the occurrence of safety accidents while staying indoors or going out, and the number of people suffering from respiratory diseases or skin diseases is rapidly increasing.

In response to this, in recent years, technology development for remotely informing a user of indoor information through a short-distance wireless communication and communication network is being actively developed. In line with this, research and development of air purifiers, humidifiers, and heating and cooling devices using the Internet of Things are actively conducted, and the supply of related equipment is rapidly increasing.

However, in the prior art, there is a problem in that the quality of service that accurately detects and informs a user who is indoors or outdoors about a change in the environment occurring indoors in real time is deteriorated. In addition, in the case of using the prior art, it is difficult to maintain an optimal indoor environment because the user determines the indoor environment based on his/her intuition and then operates the air purifier, humidifier, and air-conditioning device according to the determination result.

In order to solve this problem, a technique for detecting indoor air quality through a predetermined sensor and notifying a user is common. 1 is a configuration diagram for this.

Looking at this in general, the carbon dioxide amount sensor 10 is connected to the input terminal of the analysis device 11 to which the power (B+) is applied, the relay 12 is connected to the output terminal of the analysis device 11, and the relay 12 ), the buzzer 13 is connected to one side, so that the carbon dioxide amount sensor detects the carbon dioxide content in the room, and when the amount exceeds a certain amount, the buzzer alarms it and prevents carbon dioxide poisoning.

However, in the case of adding such a simple sensor, active operation is impossible because the detection is limited to the function of the predetermined sensor and only the user is informed of the result according to the numerical value. In particular, since the above technology is limited to detecting carbon dioxide and giving an alarm, it is practically impossible to sense various purposes and functions and to apply it in other environments through a predetermined logic.

Recently, there is a request for efficient management of sensors and environmental management facilities to collect information on various environments and lead a safe and comfortable life due to the demand for improvement of quality of life along with the expansion of object control.

The present invention has been devised to overcome the problems of the prior art, and an object of the present invention is to provide an environment monitoring and control device that can generate various environmental information, is easy to install and maintain, and has a spatial advantage.

The present invention for solving the above problem is accommodated in a housing installed on the ceiling, a plurality of sensors are mounted to generate a detection signal, the sensor module 1200, by receiving a detection signal from the sensor module to determine environmental information Functionalization to perform an operation functionalized by using any one or more of a temperature and humidity determination unit, an air quality determination unit, a fire determination unit, an occupancy determination unit, or a noise determination unit, and the determination result of the determination units as a factor according to the selected operation mode A management unit 1400 having a unit, wherein the functionalization unit collects outdoor fine dust concentrations from the atmospheric information server and collects and sets the social concentration of viruses (Vsocial) from the disaster information server based on social distancing ( 1614), an indoor/outdoor preparation unit 1621 that compares indoor and outdoor fine dust concentrations, and a control signal for whether or not the ventilation damper operates and opens according to the user's occupancy determined by the occupancy determination unit. It may include a control unit 1623 for transmitting.

Preferably, the functionalization unit controls whether or not the room is ventilated and the degree of ventilation by linking the determination result of the air quality determination unit and the occupancy determination unit.

The sensor module includes a basic sensor unit 1310 comprising at least one selected from a temperature sensor, a humidity sensor, a CO sensor, a CO2 sensor, a smoke sensor, a PM sensor, and a formaldehyde sensor, and an occupancy sensor, a microphone or a vibration sensor. Any one or more of them may be configured as a selection sensor unit 1320 that is selected and mounted.

On the other hand, it further includes a transceiver 1110 for transmitting the control signal of the management unit to the outside; the functionalization unit interlocks the determination result of the occupancy determination unit and the air quality determination unit, but uses the air quality information collected from the air information server as an outdoor air quality value. can be used to control the operation of the ventilation damper.

An output unit 1440 for outputting the determination result of the determination unit as sound or light may be included.

In addition, if the indoor fine dust concentration (PMi) is equal to or greater than the standard fine dust concentration (PMs) and the indoor fine dust concentration (PMi) is equal to or greater than the outdoor fine dust concentration (PMo), partial ventilation of the ventilation damper or maximum Select ventilation and operate the ventilation damper at minimum ventilation if the measured carbon dioxide concentration (CO2i) is higher than the reference carbon dioxide concentration (CO2s) even if the indoor fine dust concentration (PMi) is less than the outdoor fine dust concentration (PMo). Even if the concentration (PMi) is less than the outdoor fine dust concentration (PMo) and the measured carbon dioxide concentration (CO2i) is less than the reference carbon dioxide concentration (CO2s), if the social concentration (Vsocial) of the virus is above the reference value (Vs), the ventilation damper Partial ventilation or maximum ventilation can be selected.

According to the present invention, since conventional simple sensor devices fix a preset function, it overcomes the limitation of not being able to respond flexibly to changes in the environment or user's needs, selects and installs sensor modules of various functions, and automatically recognizes them. Since it can create a detection signal and operate in the selected function mode based on it, there is an effect that the usability can be maximized.

In addition, as it is installed on the ceiling, it not only has a great spatial advantage, but also enables accurate detection of environmental changes compared to other installation types of sensors. It can be used for unlimited purposes such as indoor air quality management, fire response, industrial site management, or inter-floor noise response, and has the effect of enabling optimized control of various movable devices.

In addition, it goes without saying that wireless communication with various objects to which IoT technology is applied can be performed. In this case, it may be preferable that the communication with the outside is a wireless communication method. For example, a case in which various wireless communication methods such as Zigbee, Bluetooth, RF communication, WiFi, 3G, 4G, LoRa (Long Range) communication are applied as well as a wired communication method can be considered. However, when it is installed on the ceiling and receives external power, wired communication with external equipment may be made, for example, RS485 communication may be applied.

On the other hand, a battery (not shown) may be additionally coupled to perform a sensor function as its own power source, and a case in which such a battery is also mounted in a module type may be considered.

The selection sensor unit 1320 may include an occupancy sensor, in particular, a Passive Infra-Red (PIR) sensor. In addition, it may include any one or more of a microphone 1322 for sound input and a vibration sensor 1323 for detecting vibration.

In addition, it is possible to combine various fire detection sensors (heat detection type, smoke detection type) and known sensors for sensing various gases for the detection of fire. However, various known sensor devices for generating a detection signal for environmental information may be applied to the sensors, and a combination of the basic sensor unit 1310 and the selective sensor unit 1320 may be substituted or added in the above example. .

It goes without saying that the fine dust sensor 1316 can sense only the ultrafine dust in consideration of the influence on the ultrafine dust that is not detected by the air purifier in recent years.

In addition, the occupancy sensor 1321 basically performs a function of detecting motion through infrared rays and provides a detection signal for determining whether occupancy is present to the management unit 1400 .

The occupancy sensor 1321 and/or the CO ₂ sensor 1314 and/or the fine dust sensor 1316 interwork with each other to transmit environmental information to the management unit 1400 to perform an operation for a predetermined functionalization. , specific examples thereof will be described later.

4 is a block diagram for explaining an embodiment of the management unit.

As described above, in the present invention, since it is provided as a composite sensor installed on the ceiling, it can operate in a selected mode according to individual installation environments or operating conditions. To this end, the management unit 1400 performs a basic environmental determination based on the sensing signal transmitted from each sensor of the sensor module 1200, more specifically, the basic sensor unit 1310 and/or the selection sensor unit 1320, This allows operation in each individualized and optimized functional mode. To this end, the management unit of the present invention may be configured to include logic that adapts to the environment immediately or operates in conjunction with an external artificial intelligence server.

For the basic determination, a temperature/humidity determination unit 1411 may be included. The temperature/humidity determination unit 1411 may present determination conditions so that the user can feel comfortable indoors and set appropriate temperature and humidity ranges to control the indoor air conditioner.

In addition, it may further include an air quality determination unit 1412 and receive a detection signal according to a set factor from the sensor module 1200 to compare the air quality with a reference value and the detection value to determine the air quality. In relation to the air quality _{, the detection signal of the CO 2} sensor 1314, the CO sensor 1313, or the formaldehyde sensor 1317 related to the gas and the fine dust sensor 1316 related to the particles may be involved in the detection signal. .

In addition, it may further include a fire determination unit 1420, and may receive a fire detection signal from the sensor module 1200 to determine whether there is a fire or a dangerous situation. Basically, the detection signal of the smoke sensor 1415 may function as a major factor for fire determination. In order to supplement this, a gas-related detection value or particle-related detection value may be utilized for fire determination.

In addition, it may further include an occupancy determining unit 1410, and may receive a motion detection signal from the occupancy sensor 1321 to determine whether occupancy is present. In this case, the PIR sensor can be applied as described above. On the other hand, it is also possible to measure the change in the concentration value of carbon dioxide in time series in order to supplement the judgment of occupancy.

In addition, it may further include a noise determination unit 1430, and may receive a detection signal from the microphone 1322 and/or the vibration sensor 1323 to determine whether noise is present. For example, it may be possible to make judgments about inter-floor noise or to perform warnings such as earthquakes or collapses.

The management unit 1400 may perform an alarm to notify the user when it is out of, less than, or greater than a predetermined set reference value based on the determination result of the determination unit, which operates through the output unit 1440 do. As described above, the output unit 1440 may include the sound output unit 1441 and/or the optical output unit 1442 .

In the present invention, the management unit 1400 may perform a function as a mode set through the individual determination result of the determination units or a combination thereof, and this may be variously applied according to the installation environment, location, or purpose. For this purpose, a functionalization unit 1600 is provided.

The functionalization unit 1600 receives the environmental information received from each element of the predetermined sensor module 1200 and performs a basic determination, that is, a determination on temperature and humidity, air quality, fire, occupancy, noise, etc. with a combination set in the determination units, These judgment results are combined and functionalized.

5 is a block diagram for explaining an embodiment of the functionalization unit.

As described above, the management unit 1400 may have input/output and arithmetic functions for predetermined information, and in some cases may be configured as a separate configuration connected to the outside of the housing 2000 . Accordingly, the management unit 1400 may be provided with a CPU, and according to the combination of these modules, as well as automatic recognition of each module, actively selects and performs judgments on air quality, occupancy, fire, disaster, noise, etc., and optimizes the method As a result, it will be possible to notify the user and perform the operation of an external device.

Here, the device refers to various known elements such as actuators, motors, valves, switches, and relays that can operate, for example, dampers or fans for air flow, air conditioners, outlets, sprinklers, alarms, It may be selected according to the installation environment such as the control panel of the production equipment.

An air quality management unit 1610 may be provided to operate in one mode in the functionalization unit 1600 . The air quality management unit 1610 may report the current air quality status to a user or a user terminal based on the search and determination results of gases and particles of the air quality determination unit 1412 and operate a device for air quality management.

The interlocking unit 1601 may be configured for an organic operation, and the interlocking unit 1601 may function to combine the detection values of sensor devices of different groups or the determination result of the determination unit.

For more organic and intelligent environment management, the air quality management unit 1610 generates predetermined management information based on the determination result of the air quality determination unit 1412, but the determination result of the occupancy determination unit 1410 and/or standby It is desirable to perform management based on the data of the information server. Additional embodiments related thereto will be described later.

In addition, the fire response unit 1620 may be configured to detect a fire and to evacuate a user or minimize damage. The fire response unit 1620 may basically perform a predetermined notification operation through the output unit 1440 when it is determined whether there is a fire according to the determination criteria of the fire determination unit 1420, and in addition to this, the air quality determination unit (1412) and/or the judgment result of the occupancy determination unit 1410 may be used to perform an appropriate judgment and response. For example, the occupancy determination unit 1410 receives the detection signal of the occupancy sensor 1321 constituted by the PIR sensor to determine the presence or absence of occupancy according to the movement, but when there is little or no movement, such as sleeping or static. In order to overcome the limitation of not determining the occupancy, a change in the carbon dioxide concentration in the air quality determination unit 1412 may be added and the occupancy may be determined secondarily. In this way, after the determination of whether or not occupancy is present, if there is a occupant, an alarm and a remote rescue signal may be transmitted to the user. In addition, if there is no occupant, it will be possible to perform a device command or notification for more active fire suppression.

In addition, the industrial management unit 1630 will be able to perform responses in various industrial sites, and basically improve the efficiency of work and prevent damage to human life by responding to air quality determination and fire determination within the work section. will be. As a management factor of the industrial management department, various functionalizations may be performed according to the installation environment or equipment, such as temperature, humidity, gas, fire, occupancy, vibration, noise, and the like.

In addition, based on the result determined by the noise determination unit 1430 through the detection signal input through the microphone 1322 and/or the vibration sensor 1323, the interfloor noise management unit 1640 performs a predetermined active noise removal function. It will be possible to generate a control signal for the , or perform a notification such as calling the management office.

In addition, by using the determination result of the determination units, the functionalization unit 1600 may adapt to various sites, notify the user through the environment information sensed from the ceiling, and perform an active control operation.

6 is a configuration diagram for explaining a case of operating in an air quality management mode according to an additional embodiment of the present invention.

Basically, according to the determination result by the air quality determination unit 1412 , the air quality management unit 1610 may basically display good or bad for the user's air environment on the output unit 1440 .

However, the criterion of good or bad air quality may be based on the oxygen concentration, may be based on the concentration of other gases such as carbon dioxide or carbon monoxide, and may be related to particles.

In addition, when a command for ventilation can be performed by an external device, different operations may be performed according to the presence or absence of a occupant.

In addition, depending on the difference in air quality inside and outside, the conditions for deciding whether to ventilate may be different.

In addition, it may be considered to vary the conditions for the degree of ventilation according to the level of the distance warning for the virus.

In the concept of the present invention, in consideration of this, the air quality management unit 1610 specifically sets the condition and degree of ventilation based on various factors to operate the device.

To this end, the air quality management unit 1610 is provided with an indoor/outdoor comparison unit 1611 to compare the indoor air quality and the outdoor air quality to perform a basic determination on whether to respond.

Based on the result determined through the indoor/outdoor comparison unit 1611, the response determination unit 1612 determines whether or not the operation of the device for ventilation or the degree of operation or determination of control elements such as operation time is performed.

In addition, the control unit 1613 performs a function of transmitting a control signal for the operation of the device based on the determination of the correspondence determination unit 1612 .

In the present invention, the air quality management unit 1610 controls the ventilation damper for indoor air quality control. This ventilation damper is composed of an exhaust damper 3100 and an intake damper 3200, and the control unit 1613 can basically control the opening degrees of the exhaust damper 3100 and the intake damper 3200. It is possible to perform control of a well-known blowing element such as a fan or an air conditioner capable of generating negative or positive pressure in the flow path.

On the other hand, as an element for controlling the device, comparison of indoor and outdoor air quality can be basically performed. As for the indoor air quality, it is possible to measure the indoor air quality most efficiently from the ceiling side in the sensor module 1200 itself. use value. For outdoor air quality measurement, a separate outdoor air quality sensor module may be provided to separately perform wired or wireless connection. An embodiment of the present invention proposes a method of utilizing big data in relation to the outdoor air quality. Accordingly, the air quality management unit 1610 includes a collection unit 1614 to collect information for air quality management from an external server.

The collection unit 1614 may be remotely connected to the air information server 4001 to extract air quality information from weather-related information and compare it with indoor measurement values.

In addition, the collection unit 1614 may operate in conjunction with the determination of ventilation by linking the information of the epidemic related to viruses or bacteria that can float in the air other than the air quality from the disaster information server 4002 .

In relation to air quality, the concentration of carbon dioxide and the concentration of fine dust can be mainly determined, and in the present invention, the standard for the spread of respiratory infectious diseases collected from the disaster information server 4002 can be additionally set. .

It will be described that the environmental monitoring and control device controls the ventilation system by the configuration of the air quality management unit 1610 of the present invention as described above.

7 is a flowchart illustrating operation in an air quality management mode according to the concept of the present invention.

In the environment monitoring and control device, the management unit 1400 determines the air quality according to a detection signal from the sensor module 1200 composed of a plurality of sensor devices, and the air quality management unit 1610 determines the external air quality by predetermined factors. It is possible to control the ventilation device of the as described above.

In the concept of the present invention, the air quality management unit 1610 recently has a high concentration of fine dust (PM) of public interest in relation to air quality, a concentration of carbon dioxide (CO ₂ ) related to the quality of indoor breathing, and a concentration of viruses or bacteria. Control the ventilation device by determining the factors of social distancing standards. In addition, the opening degree of the exhaust damper 3100 and the intake damper 3200 can be adjusted by interlocking the occupancy condition determined by the occupancy determination unit 1410 . Here, the external fine dust concentration is collected from the atmospheric information server 4001, and the social distance standard or social virus concentration or distribution is collected from the disaster information server 4002 by the collection unit 1624 to provide a criterion for determination.

The first step (S100) of fine dust management, the second step (S200) of carbon dioxide management, and the third step (S300) of virus management in the air related to the social distance standard of the risk of the spread of infectious diseases are judged in the order It can be seen that the higher the level, the greater the intensity of the ventilation determination.

Step 1 (S100): Fine dust management

First, the indoor fine dust concentration (PMi) measured by the sensor module 1200 disposed on the ceiling side in the air quality management unit 1610 is compared with the reference fine dust concentration (PMs) (S110), so that the indoor fine dust concentration (PMi) is If it is higher than the standard fine dust concentration (PMs), it is compared with the outdoor fine dust concentration (PMo) (S120). Here, the comparison of indoor and outdoor concentrations is performed by the indoor/outdoor contrast unit 1611 , and in relation to the operation of the damper in the description of the present invention, the corresponding determination unit 1612 is performed.

When the indoor fine dust concentration (PMi) is greater than or equal to the outdoor fine dust concentration (PMo), it can be determined that ventilation is required, and the intake damper 3200 and the exhaust damper 3100 are opened to circulate air. . Here, the fan may be operated together with the operation of the damper, and in some cases, a separate mixing damper or fan for indoor circulation may be added.

However, there is a need to control the opening rate according to the presence or absence of occupants, and the occupancy determination (S130) is additionally performed. Accordingly, when the occupancy determination unit 1410 determines that there is no occupancy, the indoor air needs to be exchanged with the outdoor air as quickly as possible, so the intake damper 3200 and the exhaust damper 3100 are opened at the maximum opening (100%) to the maximum. Ventilation (S142) is performed. However, if there is a occupant, partial ventilation (S141) is preferably performed because ventilation that is opened at the maximum opening degree may cause discomfort to the occupants. is set to 50%, but this is optional.

Second step (S200): carbon dioxide management

When ventilation is not performed in the first step, when the indoor fine dust concentration (PMi) is less than the reference fine dust concentration (PMs) (S110), and when the indoor fine dust concentration (PMi) is less than the outdoor fine dust concentration (PMo) (S120) performs the second step (S200) for carbon dioxide management.

Following the comparison result with the reference fine dust concentration (PMs), the measured carbon dioxide concentration (CO ₂ i) is compared with the reference carbon dioxide concentration (CO ₂ s) (S210). Here, if the measured carbon dioxide concentration (CO ₂ i) is greater than or equal to the reference carbon dioxide concentration (CO ₂ s), ventilation is required. If satisfied with this, the procedure for comparing the indoor and outdoor fine dust concentration (S120) may be further processed. However, according to the concept of the present invention, a high concentration of carbon dioxide is more immediately harmful to the human body than a high concentration of fine dust indoors, so the emission of carbon dioxide is greater and ventilation. Accordingly, when the measured carbon dioxide concentration (CO ₂ i) is equal to or greater than the reference carbon dioxide concentration (CO ₂ s), it is preferable to immediately perform the re-entry determination (S130). In the case of the occupancy, partial ventilation (S141) is performed, and in the case of vacancy, full ventilation (S142) is performed as described above.

In addition, in the first step, even when the indoor fine dust concentration (PMi) is less than the outdoor fine dust concentration (PMo) (S120), the separately measured carbon dioxide concentration (CO ₂ i) is compared with the reference carbon dioxide concentration (CO ₂ s) ( S220). Here, when the measured carbon dioxide concentration (CO ₂ i) is equal to or greater than the reference carbon dioxide concentration (CO ₂ s), the indoor fine dust concentration is higher than the reference value and the outdoor fine dust concentration is also higher than this. However, ventilation is necessary because the problem of oxygen shortage occurs due to excessive carbon dioxide concentration. Therefore, in this case, ventilation is performed, but the damper is operated in the minimum ventilation mode (S230). According to the preferred embodiment, the intake damper 3200 and the exhaust damper 3100 have a minimum opening degree of 10%, and additionally, indoor circulation can be maximized.

a third step (S300); Virus Management

When the comparison result (S210, S220) of the carbon dioxide concentration with the reference value is less than the reference value, in the third step (S300), the social distancing standard may be applied according to the risk of spreading the infectious disease. The social distancing may be applied to various variables such as the social concentration of the virus, the re-spreading rate, the confirmed rate, and the government guidelines for the distancing stage. In the description of the present invention, the above variables are uniformly defined and used as the viral social concentration (Vsocial). In the embodiment of the present invention, the distance standard is basically received from the disaster information server 4002 and compared with the reference value (S310).

Therefore, when the social concentration (Vsocial) of the virus is higher than the reference value (Vs), the occupancy determination step ( S130 ) may be performed and the degree of opening may be determined according to the presence of the virus. In this regard, a description that overlaps with the above will be omitted. Here, it is advantageous to set to perform maximum ventilation immediately when the room was changed to a vacant room. Therefore, if the social concentration (Vsocial) of the virus is higher than the reference value (Vs) and there is an occupancy, it is desirable to perform continuous monitoring and operate in the maximum ventilation mode immediately after the change to the vacant room.

The first to third steps may be repeatedly performed at predetermined time intervals to optimize and manage indoor air quality.

As described above, the environment monitoring and control apparatus of the present invention overcomes the limitation of being unable to flexibly respond to changes in the environment or user's needs because conventional simple sensor devices fix preset functions, and selects sensor modules of various functions. The utility can be maximized because it can be installed and automatically recognized to create a detection signal and operate in the selected function mode based on this.

In addition, as it is installed on the ceiling, it not only has a great spatial advantage, but also enables accurate detection of environmental changes compared to other installation types of sensors.
