Description

[Technical field]

[0001] The present invention relates to an indoor air measurement method and system for measuring an indoor air environment. [Background technology]

[0002] The air environment inside a room has a significant impact on the physical condition and work efficiency of the people inside the room. Therefore, it is mandatory to regularly measure indicators of the indoor environment such as "suspended dust," "carbon monoxide," "carbon dioxide," "temperature," "humidity," and "airflow."

[0003] In airtight buildings, (1) Regarding the air environment, if sufficient ventilation is not provided, there is a risk of contamination by dust and formaldehyde, etc., adverse effects on health due to carbon monoxide and carbon dioxide, and the spread of infectious diseases that are transmitted through the air or aerosols. (2) If appropriate temperature and humidity are not ensured, building occupants will be subjected to excessive stress, which may have a negative impact on their health. (3) If cooling towers, humidifiers, air conditioning equipment, etc. are not properly maintained, pathogenic microorganisms including Legionella will proliferate and cause health damage.

[0004] In order to prevent such health hazards from occurring, the Building Sanitation Act stipulates that in order to maintain and manage the sanitation of indoor environments and air conditioning equipment, etc., regular measurements and inspections must be conducted to check the indoor environment and contamination status, and cleaning and other measures must be taken based on the results. For this reason, inspectors periodically visit the objects to be inspected and record the sensor measurement results. Summary of the Invention [Problem to be solved by the invention]

[0005] However, such methods take time to detect environmental changes, and depending on the content of the survey target, it may be difficult to grasp non-routine work or sudden environmental information. Also, detecting environmental changes may require expert knowledge of the environment as well as skilled skills based on many years of experience, so there has been a demand for technology that can accurately detect environmental changes and grasp changes in environmental information from remote locations without relying on individual skills.

[0006] The present invention has been made in consideration of the above circumstances, and its purpose is to provide an indoor air measurement method and system that can remotely monitor the air environment in a room to be measured and notify the user when an abnormality occurs. [Means for solving the problem]

[0007] The present invention is an indoor air measurement method in which a computer executes the following steps: a first step of acquiring, via a network, measurement results of six inspection target items in the air being monitored, namely, suspended dust particles, carbon monoxide, carbon dioxide, temperature, humidity, and airflow; a second step of determining whether or not the measurement results for each of the six inspection target items satisfy predetermined abnormality criteria conditions; and a third step of notifying relevant persons in the room of an abnormality notification message that has been pre-associated with the inspection target item if any of the inspection target items satisfy the abnormality criteria conditions in the second step.

[0008] Preferably, the computer executes a fourth step of having information on the indoor air ventilation function in advance and generating the abnormality notification message based on the air ventilation function information, and the abnormality notification message includes the setting contents of the air ventilation function.

[0009] Preferably, a caution standard condition that does not satisfy the abnormal standard condition is defined, and a preventive message including the setting contents of the air ventilation function is generated based on the planned indoor use before the caution standard condition is satisfied, and notified to the relevant persons.

[0010] Preferably, changes in the measurement results of each of the six test items before and after the abnormality notification message is sent are detected, and based on the changes, a new message updating the settings of the air ventilation function is sent to the relevant parties.

[0011] Preferably, for each of the six inspection items, in addition to the abnormality criteria conditions, a caution criteria condition that does not satisfy the abnormality criteria condition is specified, and even if all of the six inspection items do not satisfy the abnormality criteria condition, if a predetermined number of the six inspection items satisfy the caution criteria condition, a pre-warning message is sent to the relevant person.

[0012] Preferably, the performance of the air ventilation function is judged based on the change by comparing it with a predetermined standard, and if the performance is insufficient, a message indicating that fact is sent to the relevant person.

[0013] Preferably, changes in the measurement results of each of the six test items before and after the abnormality notification message is sent are detected, and based on the changes, a new message updating the settings of the air ventilation function is sent to the relevant parties.

[0014] Preferably, the performance of the air ventilation function is judged based on a predetermined standard on the basis of the change, and if the performance is insufficient, a message indicating that fact is sent to the relevant person.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an indoor air measurement method and system thereof according to an embodiment of the present invention will be described. The indoor air measurement system of this embodiment inspects and remotely monitors six target items in indoor air: suspended dust, carbon monoxide, carbon dioxide, temperature, humidity, and airflow.

[0020] First Embodiment FIG. 1 is a diagram for explaining an indoor air measuring system 1 according to a first embodiment of the present invention. As shown in FIG. 1, indoor air measurement system 1 measures indoor air in a plurality of measurement target rooms 4.

[0021] FIG. 2 is a diagram for explaining the measurement target chamber 4 shown in FIG. 2, sensors 21 that measure six test items, namely, "suspended dust," "carbon monoxide," "carbon dioxide," "temperature," "humidity," and "airflow," are installed at one or more locations in the measurement target room 4. The measurement target room 4 is provided with a communication device 23 that transmits measurement information from the sensors 21 installed in the measurement target room 4 to the indoor air measurement system 1.

[0022] The indoor air measurement system 1 receives measurement information for the above six test target items from the communication devices 23 in the multiple measurement target rooms 4.

[0023] FIG. 3 is a functional block diagram of the indoor air measuring system 1 shown in FIG. As shown in FIG. 3, the indoor air measuring system 1 has, for example, a display 51, an input unit 53, a communication unit 55, a memory 59, and a processing unit (CPU) 61, which are all housed in the same housing.

[0024] The display 51 displays a screen based on a signal from the processing unit 61 .

[0025] The input unit 53 is an interface for inputting operation information from an operating means such as a touch panel, a keyboard, or a mouse. The communication unit 55 communicates with the terminal devices of the people involved in the measurement target room 4 . The memory 59 stores the program executed by the processing unit 61 . The processing unit 61 executes the program PRG1 stored in the memory 59 to perform the processing of the indoor air measuring system 1 defined in this embodiment.

[0026] The memory 59 stores the notification destination (notification address, etc.) of the notifier for each of the measurement target rooms 4 shown in FIG. The memory 59 also stores air ventilation function information for each measurement target room 4. The air ventilation function includes, for example, automatic or manual opening and closing of windows, the type of air conditioning equipment, and the like.

[0027] FIG. 4 is a flowchart for explaining the operation of transmitting measurement information from the sensor 21 in the measurement target room 4 to the indoor air measurement system 1 in this embodiment. Step ST11; In the measurement target room 4, the measurement information of the sensor 21 is stored in the memory of the communication device .

[0028] STEP ST12: The communication device 23 judges whether or not a predetermined time interval or a predetermined measurement information transmission time has arrived, and if the judgment is positive, the process proceeds to step ST13.

[0029] STEP ST13: The communication device 23 reads out the measurement information from the memory and transmits it to the indoor air measurement system 1.

[0030] STEP ST14: The indoor air measuring system 1 stores the measurement information received in step ST13 in the memory 59 shown in FIG.

[0031] FIG. 5 is a flow chart for explaining the flow of determining whether there is an abnormality in the air environment of measurement target room 4 in indoor air measurement system 1 shown in FIG. STEP ST21: When the predetermined abnormality determination time arrives, the processing unit 61 of the indoor air measuring system 1 proceeds to step ST22.

[0032] STEP ST22: The processing unit 61 reads out the measurement information of the above six test items for each measurement chamber 4 from the memory 59 . Then, the processing unit 61 judges whether or not the six pieces of read measurement information satisfy the abnormality criteria conditions defined for each of them.

[0033] STEP ST23: If at least one piece of measurement information satisfies the abnormality criterion condition in step ST22, the processing unit 61 proceeds to step ST24.

[0034] STEP ST24: The processing unit 61 performs processing for notifying the relevant persons in the measurement target room 4 of the abnormality occurrence message.

[0035] FIG. 6 is a flow chart for explaining a case where an abnormality occurrence message is sent based on the air ventilation function information. In FIG. 6, steps denoted with the same reference numerals as in FIG. 5 are the same as the steps described above. STEP ST31: The processing unit 61 reads out from the memory 59 the air ventilation function information of the measurement target room 4 that satisfies the abnormality criteria conditions, and generates an abnormality occurrence message based on that information. At this time, the processing unit 61 generates an abnormality occurrence message including ventilation proposal information regarding how to operate the air ventilation function of the measurement target room 4, depending on the content of the measurement information. For example, the ventilation suggestion information includes the time to open the windows, the air conditioning settings, and removing people from the room.

[0036] FIG. 7 is a flow chart for explaining a case in which a pre-caution message is further transmitted in FIG. In FIG. 7, steps denoted with the same reference numerals as in FIG. 6 are the same as the steps described above. Step ST41: If at least one piece of measurement information satisfies the abnormality criterion condition in step ST22, the processing unit 61 proceeds to step ST31, otherwise proceeds to step ST42.

[0037] STEP ST42: The processing unit 61 reads out the measurement information of the above six test items for each measurement chamber 4 from the memory 59 . Then, the processing unit 61 judges whether or not the six pieces of read measurement information satisfy the caution criterion conditions defined for each of them, and judges whether or not a predetermined number of test target items satisfy the caution criterion conditions.

[0038] STEP ST43: If the determination in step ST42 is positive, the processing unit 61 proceeds to step ST44, and if not, ends the processing.

[0039] STEP ST44: The processor 61 generates a warning message and notifies the relevant persons.

[0040] In the above-described embodiment, the abnormality occurrence message or the advance warning message may be transmitted to a terminal device of a person involved in the measurement target room 4, or an alarm lamp disposed in the management system that manages the measurement target room 4 may be turned on. Also, an alarm sound may be output.

[0041] As described above, the indoor air measurement system 1 can remotely monitor the air environment in the measurement target room 4 and, if necessary, send an abnormality notification message to relevant persons in the measurement target room 4. Therefore, the relevant persons can improve the air environment in the measurement target room 4 based on the message.

[0042] Furthermore, according to the indoor air measurement system 1, the abnormality notification message includes settings corresponding to the air ventilation function of the measurement target room 4, so that the relevant parties can easily understand what to do specifically. Furthermore, the air ventilation device in the measurement target room 4 can be automatically operated based on the settings.

[0043] Furthermore, according to the indoor air measurement system 1, even if the abnormality criteria conditions are not met, a message is sent if the caution criteria conditions are met, making it possible to take appropriate action before the air environment in the measurement target room 4 becomes abnormal.

[0044] <Second embodiment> FIG. 8 is a flow chart for explaining the processing of the indoor air measuring system 1 according to the second embodiment of the present invention. In FIG. 8, steps denoted by the same reference numerals as in FIG. 6 are the same as the steps described above.

[0045] STEP ST51: The processing unit 61 of the indoor air measurement system 1 determines whether or not the settings of the air ventilation function need to be updated (whether or not the abnormality message needs to be resent) based on the changes in the measurement information measured in the measurement target room 4 after notifying relevant parties of the abnormality message in step ST32 (changes before and after the notification). For example, after sending the abnormality occurrence message in step ST32, if a change in the measurement information indicates that an improvement has been observed in the test target item but is insufficient, it is determined that an update is necessary.

[0046] STEP ST52: If it is determined in step ST51 that the abnormality occurrence message needs to be retransmitted, the process proceeds to step ST53, and if not, the process ends.

[0047] STEP ST53: The processing unit 61 again performs processing to notify the relevant persons in the corresponding measurement target room 4 of the abnormality occurrence message including the updated setting contents of the air ventilation function.

[0048] In this embodiment, the performance of the air ventilation function is judged by comparing it with a predetermined standard based on the change in the measurement information before and after the transmission of the above-mentioned abnormality occurrence message, and if the performance is insufficient, a message indicating that fact is notified to the relevant person. This makes it possible to work on improving the air ventilation function in the measurement target room 4 if it is insufficient. At this time, information on improvements made in multiple measurement target rooms 4 may be obtained, and information on improvements made in other measurement target rooms 4 with the same or similar air ventilation functions that have had a certain degree of effect may be notified to those involved in the target measurement rooms 4.

[0049] As described above, according to the second embodiment, after the relevant person performs ventilation in the measurement target room 4 based on the settings of the air ventilation function included in the abnormality occurrence message, the indoor air measurement system 1 can determine the ventilation effect from the changes, and if the effect is insufficient, a message including further settings based on the results can be sent. This makes it possible to take appropriate ventilation measures.

[0050] In this embodiment, AI technology may be employed to estimate what kind of environmental change has occurred in the measurement target room 4 and to what extent. The indoor air measurement system 1 uses AI to analyze the measurement information received from the sensor 21 and predict future environmental changes.

[0051] The present invention is not limited to the above-described embodiments. In other words, those skilled in the art may make various modifications, combinations, sub-combinations, and substitutions of the components of the above-described embodiment within the technical scope of the present invention or an equivalent scope.
