FIG. 2 is a block diagram of the environmental information management system shown in FIG. 1.
3 to 4 are flowcharts illustrating a method of managing indoor environment information related to an embodiment of the present invention.

Hereinafter, a method of managing indoor environment information using an environment information management system related to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a view for explaining a method for managing indoor environment information related to an embodiment of the present invention.

As shown in FIG. 1, the air space 110 and the water quality measurer 120 may be installed in the indoor space 100 to measure a state of the indoor environment.

The air measuring unit 110 may measure the air state of the indoor space. The air condition of the indoor space may include temperature, humidity, components, and the like of the indoor air. The air measuring unit 110 may be composed of a plurality of measuring sensors, or may be composed of one integrated measuring sensor.

In particular, the air measuring unit 110 may measure the absolute amount or relative amount of harmful pollutants when measuring the components of the indoor air. The absolute amount may refer to the amount of the corresponding component (eg, weight, volume) calculated regardless of which component, and the relative amount may refer to the amount (eg, concentration) of the component for a component. The content may be specific ingredient information. The specific component information may be content information on a plurality of components. Hazardous pollutants exist in various ways, and examples of harmful substances in indoor spaces, such as apartment houses, include formaldehyde and volatile organic compounds. Formaldehyde (HCHO, Formaldehyde) is a colorless transparent gas with a strong irritant odor, and has human toxicity such as acute toxicity, skin irritation and carcinogenicity. In addition, volatile organic compounds (VOCs) are liquid or gaseous organic compounds that have a low boiling point (boiling point) and are easily evaporated into the atmosphere. Organic compounds such as liquid fuels, paraffins, olefins, and aromatic compounds commonly used around life are volatile organic compounds, and building materials, laundry solvents, and paints can be the main causes of occurrence indoors. Typical volatile organic compounds include toluene, benzene, ethylbenzene, xylene and styrene. In addition, other harmful substances include fine dust, carbon dioxide, airborne bacteria, carbon monoxide, nitrogen dioxide, radon, asbestos, ozone, and the like.

In addition, the air measuring unit 110 may measure the temperature and humidity of the indoor air. The temperature and humidity of the indoor air can be kept constant based on the measured values of the temperature and humidity of the indoor air, thereby making the indoor air comfortable. Depending on the season, the standard values of temperature and humidity may be different to create a comfortable indoor air. For example, in summer, the temperature is 24 ~ 28 ℃, humidity is 60%, in spring and autumn, the temperature is 19 ~ 23 ℃, the humidity is 50%, and in winter, the temperature is 18 ~ 20 ℃ Maintaining at 40% may be a reference value for creating comfortable indoor air.

In addition, the water quality measurement unit 120 may be attached to the inlet of the tap water flowing into the indoor space 100 to measure the absolute amount or relative amount of the tap water component introduced. For example, the water quality measurement unit 120 is attached to the main water use point, such as tap water inlet or faucet, such as water tanks installed in apartments, office buildings, schools, etc. to measure tap water flowing in real time according to the measurement items. The measured value can be obtained.

The water quality measurement unit 120 may be composed of a plurality of measurement sensors, or may be composed of one integrated measurement sensor. The measurement method used to measure the tap water in the water quality measurement unit 120 includes an electrode method and an absorbance method, but of course, other measurement methods may be used. The electrode method is a method of measuring the type and concentration of a substance contained in the tap water by using a potential difference, the absorbance method is a measure of the wavelength and degree of light absorbed by the generated material when the substance contained in the tap water and the standard chemical reacts. It is a method of measuring the type and concentration of substances contained in tap water. When measuring tap water by electrode method or absorbance method, possible measurement items include turbidity, nitrogen nitrate, water temperature, hydrogen ion concentration, residual chlorine concentration, heavy metal content, and inorganic ionic substance concentration.

At least one of the air condition measurement value obtained by the air measurement unit 110 and the measurement value of the tap water component obtained by the water quality measurement unit 120 may be transmitted to the environmental information management system 200 through a specific communication means. have. The environmental information management system 200 determines whether or not the indoor environment is stable based on the received air condition measurement value or the measurement value of the tap water component obtained by the water quality measurement unit 120, and determines the determined result as a specific communication means. It can be transmitted to the display unit 130 installed in the indoor space 100 by using.

The display unit 130 may include an electronic device provided with a display device. For example, it may include a TV screen, a monitor of a PC, and the like. The display unit 130 may display various information about the indoor environment state. For example, the display 130 may display information on whether the current safety of indoor air, information on indoor air pollution source, information on safety of tap water, information on water pollution source, and the like.

An example of a method using the specific communication means is a method using a home network, a wired Internet, or a wireless communication.

 Wireless communication refers to the communication of information such as signals, codes, video, and audio through radio waves, rather than through wires. Wireless communication technologies include wireless networks, wireless Internet, wireless LAN, mobile communication, and near field communication.

In addition, when the indoor environment is not safe, the environmental information management system 200 may generate an alarm signal for an indoor environmental risk and transmit the generated alarm signal to the alarm unit 140 installed in the indoor space. Then, the alarm unit 140 may output the received alarm signal to allow the user to recognize that the indoor environment is not safe. The alarm signal output may be an audio signal or a video signal. When the output alarm signal is an audio signal, the alarm unit 140 may be implemented in the form of a speaker. The alarm signal may be classified according to the degree of danger. For example, an alarm signal may be classified into a dangerous first level alarm signal, a dangerous second level alarm signal, and a dangerous three level alarm signal. In addition, when the output alarm signal is a video signal, it may be implemented in the form of a display device. In this case, the alarm unit 140 may be the same as the display unit 130 or may be a separate module from the display unit 130.

Although not shown, the indoor space 100 may further include a sensor capable of measuring other indoor environments in addition to the air measuring unit 110 and the water quality measuring unit 120. For example, the indoor space 100 may be provided with a sensor that can measure the noise or vibration. The vibration sensor and the noise sensor may be provided separately, but may be integrated and implemented as one. In addition, the vibration sensor also serves as a noise sensor.

Examples of the vibration sensor include a vibration sensor implemented by equipment using MEMS (micro electro-mechanical systems) and a vibration sensor using a resonance mode. Equipment using MEMS (micro electro-mechanical systems) creates a fine structure using semiconductor technology, and when the structure itself is tilted in accordance with the acceleration direction, the resistance value changes so that the value of the current flowing through the structure changes and the current change is recognized as an acceleration. Done. Commercial vibration sensors may be provided with two acceleration sensors in the XY direction.

In addition, in the vibration sensor using the resonance mode, an object connected to the spring receives a force according to the acceleration. The vibration sensor measures the tension applied to the spring and uses the acceleration information. Using this method, a high bandwidth signal can be obtained. The field of application can be applied in systems where it is difficult to attach a position sensor such as a guided missile or when the resolution of the position information is very low and difficult to use for control.

Next, a specific example of a method of managing indoor environmental information through the environmental information management system 200 will be described.

2 is a block diagram of an environmental information management system 200.

The illustrated environmental information management system 200 may include a receiver 210, a database 220, an analyzer 230, a transmitter 240, an output unit 250, a controller 260, and the like.

The receiver 210 may receive at least one of an air measurement unit 110 installed in an indoor space, an air condition measurement value obtained through the water quality measurement unit 120, and a measurement value of tap water components through a specific communication means. have. The air condition measurement value is a measurement value of the air condition present in the indoor space, and may include air temperature, air humidity, air component, and the like. In this specification, the humidity of the air means the humidity of the indoor space. The receiver 210 may receive the air condition measurement value or the measurement value of the tap water component at predetermined intervals. In addition, the receiver 210 may also receive measurement results such as vibration or noise.

The database 220 may store at least one of the received air condition measurement value, the tap water component measurement value, and the vibration or noise measurement value. In this case, the database 220 may store the measurement date together with the air condition measurement value or the tap water component measurement value or the vibration or noise measurement value. When the receiver 210 receives the air condition measurement value or the measurement value of the tap water component or the measurement value of the vibration or noise at a predetermined cycle, the database 220 includes a plurality of measurement data (state measurement value or the measurement value of the tap water component). Can be stored. The database 220 may automatically delete data (measurement value of air condition or measurement value of tap water component) whose measurement date has passed a predetermined period by the control of the controller 260 which will be described later. By automatically deleting the data, the storage space of the database 220 may be efficiently utilized.

In addition, the database 220 may store a safety indoor environment state reference value. The reference value of the safe indoor environment state may refer to reference information for determining safety of the indoor environment. For example, the safety indoor environmental condition reference value may include reference information that should not be exceeded certain hazardous substances in order to create a safe indoor environment, and may also include information on the optimal condition range for a comfortable indoor environment. The safe indoor environmental condition reference value may include a safe air condition reference value for a safe air condition, a safe water quality reference value for a safe tap water condition, a safety reference value for vibration or noise, and the like.

The safe indoor environmental condition reference value may be determined by legal regulations or may be determined through experiments. In addition, the safe indoor environmental condition reference value is not uniform but may vary according to the situation of the indoor space 100. For example, if the indoor space 100 is a residential space, since the management criteria may be set differently for each occupancy period, the safety air condition reference value may vary according to the occupancy period.

For example, the safe air condition reference value may be stored in the database 220 as shown in Table 1. The measurement items listed in Table 1 exemplarily show only some items, and the measurement items are not limited to the items shown in Table 1 below.

Metric Safety air condition reference value Formaldehyde 210 µg / ㎥ or less benzene 30 ㎍ / ㎥ or less toluene 1,000 ㎍ / ㎥ or less Ethylbenzene 360 µg / ㎥ or less Xylene 700 µg / ㎥ or less Styrene 300 µg / ㎥ or less

If it is determined whether the indoor air is safe based on the safety air condition reference values described in Table 1, for example, when the amount of formaldehyde contained in the indoor air exceeds 210 µg / m 3, it may be determined that the indoor air is not safe. The reference value may be determined that the indoor air is safe only when all of the measured items are determined to be safe. Therefore, when it is determined that any one of the measurement items is not safe, the air in the indoor space 100 may be determined to be unsafe.

In addition, the safe water quality reference value of the tap water may be stored in the database 220 in the form shown in Table 2. The measurement items listed in Table 2 exemplarily show only some items, and the measurement items are not limited to the items shown in Table 1 below.

Metric Safety water quality standard value (based on drinking water) Ammonia nitrogen 0.5 mg / l or less Nitrate Nitrogen 10 mg / l or less Hydrogen ion 5.8 ~ 8.5 pH Chlorine Ion 250mg / l or less Evaporation residue 500mg / l or less

If the safety of the tap water is determined according to the safe water quality reference values listed in Table 2, for example, if the concentration of chlorine ions contained in the tap water exceeds 250 mg / l, it can be determined that the tap water is not safe. Also, in general, the reference value may be determined that the indoor air is safe only when all of the measurement items are determined to be safe. Therefore, when it is determined that any one of the measurement items is not safe, it may be determined that the tap water flowing into the indoor space 100 is not safe.

The analysis unit 230 may determine whether the air present in the indoor space 100 is safe by comparing the air state measurement value received from the air measuring unit 110 with the previously stored safety air state reference value. As shown in Table 1, the analysis unit 230 may determine that the air condition of the indoor space 100 is not safe when the measured value of the measurement item deviates from the safe air condition reference value.

In addition, when the air condition measurement value is received from the air measurement unit 110 at a predetermined period, the analysis unit 230 may extract a trend of change of the measurement value based on the air condition measurement value. The analysis unit 230 may determine a source of air pollution based on the extracted change trend. If the safe air condition thresholds for volatile organic compounds (benzene, ethylbenzene, toluene, etc.) are not exceeded, but the measured values continue to increase, the use of certain household or office supplies is increasing. For example, since insecticides, sprays, fragrances, and detergents contain volatile organic compounds, if the measured values of the volatile organic compounds received at predetermined intervals tend to increase, the amount of household goods such as pesticides, sprays, fragrances, and detergents is used. It can be predicted that this is increasing.

The analysis unit 230 may determine whether the tap water flowing into the indoor space 100 is safe by comparing the measured value of the tap water component received from the water quality measuring unit 120 with the previously stored safety water quality reference value. As shown in Table 2, the analysis unit 230 may determine that the tap water flowing into the indoor space 100 is not safe when the measured value of the measurement item deviates from the safe water quality reference value.

In addition, when the measurement value of the tap water component is received from the water quality measurement unit 120 at a predetermined cycle, the analysis unit 230 may extract a change trend of the measured value based on the measurement value of the tap water component. The analysis unit 230 may determine the pollution source of water based on the extracted change trend. For example, if other metrics meet the safety water quality standard without any significant change, while iron content continues to increase, it may be determined that water is contaminated by corrosion in the tank or pipe.

On the other hand, the transmission unit 240 information on whether the safety of the environmental conditions of the indoor space 100 (air safety, tap water safety, etc.) and environmental pollution sources (air pollution source, water pollution source) of the indoor space 100 Etc.) may be transmitted to the indoor space 100. For example, the transmitted information may be transmitted to the display unit 130 installed in the indoor space 100. In this case, the display 130 may display information on whether or not the received environmental condition of the indoor space 100 is safe and / or information on environmental pollution sources of the indoor space 100.

In addition, the output unit 250 is information on the safety of the environmental conditions of the indoor space (100, whether the safety of the air, whether the safety of the tap water, whether the vibration or noise safety, etc.) and the environment of the indoor space 100 At least one of information on a pollution source (air pollution source, water pollution source, etc.) may be output. The output unit 250 may be implemented as an output means such as an audio output means or a video output means.

The controller 260 may control the receiver 210, the database 220, the analyzer 230, the transmitter 240, the output unit 250, and the like.

3 to 4 are flowcharts illustrating a method of managing indoor environment information related to an embodiment of the present invention.

First, a method of managing the air condition of the indoor space 100 will be described with reference to FIG. 3.

The air measuring unit 110 may measure the air state of the indoor space 100. That is, the air measuring unit 110 measures the temperature, humidity, and the like of the air present in the indoor space 100 at a predetermined period (for example, one week, one month, etc.) to obtain a measured value. It may be (S310). In particular, measurement items of air components may include harmful substances such as formaldehyde, volatile organic compounds, carbon dioxide, and carbon monoxide.

The receiver 210 of the environmental information management system 200 may receive a measurement value of the air state measured at a predetermined cycle through a specific communication means (S320). The received air condition measurement is then stored in the database 220. In this case, the air state measurement value may be stored together with the measurement date (S330).

The analysis unit 230 may determine whether the air present in the indoor space 100 is safe by comparing the air state measurement value received from the air measurement unit 110 with the pre-stored safety air state reference value stored in the database 220. It may be (S340, S350). When the measured value of the measurement item is outside the safe air condition reference value, the analysis unit 230 may determine that the air condition of the indoor space 100 is not safe. In this case, the analyzer 230 may generate a warning signal (S360). For example, the pre-stored safety air condition reference value may include the safety air condition reference value for measurement items such as formaldehyde, volatile organic compounds, carbon dioxide, carbon monoxide, suspended bacteria, nitrogen dioxide, radon, asbestos, and ozone.

In addition, if it is determined that the air condition is unsafe, the analyzer 230 may also generate information on the countermeasure. For example, when harmful substances exist in the indoor space 100 or more, the information may be generated to increase the temperature of the indoor space 100 to perform ventilation. In addition, when it is determined that the air condition is unsafe, the analyzer 230 may generate a command signal related to environmental control of the indoor space 100 related to the countermeasure. For example, when harmful substances exist in the indoor space 100 or more, a control signal for raising the temperature of the indoor space 100 may be generated.

On the other hand, the analysis unit 230, based on the air state measurement value stored in the database 220 may extract the change trend of the measurement value. The analysis unit 230 may determine a source of air pollution based on the extracted change trend (S370). If the safe air condition thresholds for volatile organic compounds (benzene, ethylbenzene, toluene, etc.) are not exceeded, but the measured values continue to increase, the use of certain household or office supplies is increasing. For example, since insecticides, sprays, fragrances, and detergents contain volatile organic compounds, if the measured values of the volatile organic compounds received at predetermined intervals tend to increase, the amount of household goods such as pesticides, sprays, fragrances, and detergents is used. It can be predicted that this is increasing. In this case, the analyzer 230 may generate information on the countermeasure or a control signal for the countermeasure based on the information on the determination of the air pollution source.

The transmitter 240 may transmit information on whether the air safety is determined by the analyzer 230 and / or information on an air pollution source to the indoor space 100 (S380). For example, the transmitter 240 may transmit information on whether air is safe and / or information on an air pollution source to the display 130 of the indoor space 100. In this case, the display unit 130 displays information on whether the received air safety and / or information about the air pollution source. In addition, the information on whether the air safety and / or information about the air pollution source may also include a warning signal (eg, toxic alarm).

On the other hand, when it is determined that the air condition is unsafe or when there is an air pollutant, the transmitter 240 may transmit a control signal related to the countermeasure of the indoor environment to the indoor space 100. The control signal may include a control signal for automatically controlling the facilities provided in the indoor space 100. For example, when it is determined that the air condition of the indoor space 100 is not safe (that is, when certain harmful substances exceed the reference value), a control signal for controlling the temperature of the indoor space 100 is provided. It may transmit to a temperature control unit (not shown) of the space 100. Temperature control unit (not shown) of the indoor space 100 The temperature of the indoor space may be automatically controlled based on the received control signal. The temperature control unit (not shown) of the indoor space 100 may receive a control signal for increasing the temperature of the indoor space 100 from the transmitter 240 to increase the temperature of the indoor space 100. After increasing the temperature to temporarily increase the amount of harmful substances emitted from building materials, etc., it is possible to remove the contaminants in the interior space 100 through ventilation.

In addition, when it is determined that the air condition is unsafe or when there is an air pollutant, the transmitter 240 may transmit information about the countermeasure of the indoor environmental condition to the indoor space 100. Therefore, a manager or a resident of the indoor space 100 may conveniently prepare a countermeasure based on the countermeasure.

Next, a method of managing tap water flowing into the indoor space 100 will be described with reference to FIG. 4.

The water quality measuring unit 120 may measure a component of tap water introduced into the indoor space 100. That is, the water quality measurement unit 120 may measure a component of the tap water flowing into the indoor space 100 at a predetermined period (for example, one week, one month, etc.) to obtain a measured value (S410). . In particular, the measurement items of tap water components may include residual chlorine concentration, nitrate nitrogen concentration, hydrogen ion concentration, heavy metal content, turbidity, and inorganic ionic substance concentration.

The receiver 210 of the environmental information management system 200 may receive a measurement value of the tap water component measured at a predetermined cycle through a specific communication means (S420). The received tap water component measurement value is stored in the database 220. In this case, the tap water component measurement value may be stored together with the measurement date (S430).

The analysis unit 230 may determine whether the tap water introduced into the indoor space 100 is safe by comparing the tap water component measurement value stored in the database 220 and the previously stored safety water quality reference value received from the water quality measurement unit 120. There is (S440, S450). If the measured value of the measurement item is outside the safe water quality reference value, the analysis unit 230 may determine that the tap water flowing into the indoor space 100 is not safe. In this case, the analyzer 230 may generate a warning signal (S460). For example, the pre-stored safety water quality reference value may include safety water quality reference values for measurement items such as residual chlorine concentration, nitrate nitrogen concentration, hydrogen ion concentration, heavy metal content, turbidity, and inorganic ionic substance concentration.

In addition, the analysis unit 230 may generate information on the countermeasures if it is determined that the tap water is not safe.

On the other hand, the analysis unit 230, based on the tap water component measured value stored in the database 220 may extract the change in the measured value. The analysis unit 230 may determine a water pollution source based on the extracted change trend (S470). For example, if other metrics meet the safety water quality standard without any significant change, while iron content continues to increase, it may be determined that water is contaminated by corrosion in the tank or pipe. In this case, the analyzer 230 may generate information on the countermeasure or a control signal for the countermeasure based on the information on the determination of the water pollution source. For example, if the iron content contained in the tap water continuously increases, the analysis unit 230 may determine the water pollution source as the corrosion of the tube, to generate information to replace the tube.

The transmitter 240 may transmit the information on the safety of the tap water and / or information about the water pollution source determined by the analyzer 230 to the indoor space 100 (S480). For example, the transmitter 240 may transmit information on whether the tap water is safe and / or information about a water pollution source to the display 130 of the indoor space 100. In this case, the display 130 displays information on whether the received tap water is safe and / or information on water pollution sources. In addition, the information on the safety of the tap water and / or the information on the water pollution source may also include a warning signal (eg, toxic alarm).

On the other hand, if it is determined that the tap water is not safe or the source of water pollution is determined, the transmitter 240 may transmit a control signal related to the countermeasure of the indoor environment to the indoor space 100. The control signal may include a control signal for automatically controlling the facilities provided in the indoor space 100.

In addition, when it is determined that the tap water is not safe or when there is a source of water pollution, the transmission unit 240 may transmit information about the countermeasure of the indoor environmental condition to the indoor space 100. Therefore, a manager or a resident of the indoor space 100 may conveniently prepare a countermeasure based on the countermeasure.

In this case, the computer-readable recording medium may include program instructions, data files, data structures, and the like, alone or in combination. On the other hand, the program instructions recorded on the recording medium may be those specially designed and configured for the present invention or may be available to those skilled in the art of computer software.

The computer-readable recording medium includes a magnetic recording medium such as a magnetic medium such as a hard disk, a floppy disk and a magnetic tape, an optical medium such as a CD-ROM and a DVD, a magnetic disk such as a floppy disk, A magneto-optical media, and a hardware device specifically configured to store and execute program instructions such as ROM, RAM, flash memory, and the like. The recording medium may be a transmission medium such as an optical or metal wire, a waveguide, or the like including a carrier wave for transmitting a signal specifying a program command, a data structure, or the like.

In addition, program instructions include not only machine code generated by a compiler, but also high-level language code that can be executed by a computer using an interpreter or the like.
