At this time, the infectious disease transmission zone identification server (200) can receive an entrant ID (501), a space ID (502), an entry date and time (503), an exit date and time (504), etc. Here, the entrant ID (501) may be an identifier for an infected person among entrants. For example, the infectious disease transmission zone identification server (200) may receive the entrant ID (501) as 20230001, 20230002, etc. Meanwhile, the space ID (502) may be an identifier for an area where an infected person stayed among multiple areas. For example, the infectious disease transmission zone identification server (200) may receive the space ID (502) as B, C, D, F, etc. Additionally, the entry date and time (503) may be the time an infected person enters the area where the person stayed among multiple areas.

Furthermore, the exit date and time (504) may be the time an infected person leaves the area where the person stayed. For example, the infectious disease transmission area identification server (200) may receive the exit date and time (504) as approximately 3:00 PM on October 1, 2023.

[0092] Referring to FIG. 6, the infectious disease transmission zone identification server (200) may provide a user interface illustrating a stay zone among a plurality of zones. At this time, the infectious disease transmission zone identification server (200) may provide a user interface illustrating the locations of a stay zone (601) among the plurality of zones, an identifier of the stay zone and a zone connected to the stay zone, a spatial pressure measurement sensor (602) measuring the pressure of the stay zone, and a spatial pressure measurement sensor (603) measuring the pressure of the zone connected to the stay zone.

[0093] Referring to FIG. 7A, the infectious disease transmission zone identification server (200) can receive data for multiple spaces. At this time, the infectious disease transmission zone identification server (200) can receive a space name (701), a space ID (702), a space type (703), space coordinates (704), etc. Here, the space name (701) can be a name for multiple zones. For example, the infectious disease transmission zone identification server (200) can receive the zone name (701) as Ward 201, Nursing Station, Ward 202, etc. Meanwhile, the space ID (702) can be an identifier for multiple zones. For example, the infectious disease transmission zone identification server (200) can receive the space ID (702) as A, B, C, D, E, etc. In addition, the space type (703) can be a characteristic according to the shape of the multiple zones. At this time, the space type (703) may include open, room, closed, partially open, corridor, etc. In addition, the space coordinates (704) may be the vertex coordinates of the borders of each of the multiple zones. For example, the infectious disease transmission zone identification server (200) may receive the space coordinates (704) as 0x0, 0x25, etc.

[0094] Referring to FIG. 7b, the infectious disease transmission zone identification server (200) can receive data on spatial pressure measurement sensors installed in multiple spaces. At this time, the infectious disease transmission zone identification server (200) can receive a device ID (705), a device location (706), an installation space ID (707), an installation type (708), etc. Here, the device ID (705) may be an identifier for the spatial pressure measurement sensor. For example, the infectious disease transmission zone identification server (200) may receive the device ID (705) as DEV001, DEV002, etc. Meanwhile, the device location (706) may be a coordinate for the location where each spatial pressure measurement sensor is installed. For example, the infectious disease transmission zone identification server (200) may receive the device location (706) as (10,9), (8,9), etc. In addition, the installation space ID (707) may be an identifier for the area where the spatial pressure measurement sensor is installed. At this time, the installation space ID (707) may include A, B, D, E, etc. In addition, the installation type (708) may be the installation type of the area where the spatial pressure measurement sensor is installed. For example, the infectious disease transmission area identification server (200) may receive the installation type (708) as internal, external, etc.

[0095] Returning to Figure 4, the infectious disease transmission zone identification server (200) receives the atmospheric pressure measured for the stay zone and the first zone from the spatial pressure measurement sensor (S420). The first zone may be an area connected to the stay zone and air circulation. Here, the spatial pressure measurement sensor may be installed on the wall of a passage connecting the stay zone and the first zone to allow air circulation.

[0096] Next, the infectious disease transmission zone identification server (200) determines the stay zone to have either negative or positive pressure (S430). At this time, the infectious disease transmission zone identification server (200) may determine the stay zone to have either negative or positive pressure based on the air pressure of the stay zone and the first zone. Here, the infectious disease transmission zone identification server (200) may determine the stay zone to have negative pressure when the air pressure of the stay zone is lower than the air pressure of the first zone. Additionally, the infectious disease transmission zone identification server (200) may determine the stay zone to have positive pressure when the air pressure of the stay zone is higher than the air pressure of the first zone. For example, when the air pressure of the stay zone is 1.3 atm and the air pressure of the first zone is 0.8 atm, the stay zone may be determined to have positive pressure and the first zone to have negative pressure.

[0097] Next, the infectious disease transmission zone identification server (200) determines the transmission zone for the infectious disease based on whether the stay zone has negative or positive pressure (S440). At this time, if the stay zone has negative pressure, the infectious disease transmission zone identification server (200) can determine only the stay zone as the transmission zone. Here, if the stay zone has positive pressure, the infectious disease transmission zone identification server (200) can receive a list of second zones connected to the first zone so that air can pass through them. In addition, the infectious disease transmission zone identification server (200) can receive the air pressure of the second zone measured from the spatial air pressure measurement sensor and the third zone adjacent to the second zone and connected to the stay zone. In addition, the infectious disease transmission zone identification server (200) can determine each of the second zones as having either negative or positive pressure based on the air pressure of the first zone and the second zone. At this time, the infectious disease transmission zone identification server (200) may determine the stay zone, the first zone, and the second zone as transmission zones if the second zone is determined to have negative pressure. Here, the infectious disease transmission zone identification server (200) may determine the second zone as not a transmission zone if the second zone is determined to have positive pressure, and may determine the stay zone and the first zone as transmission zones.

[0098] Additionally, the infectious disease transmission zone identification server (200) can receive entry history data for individuals entering multiple zones. At this time, the infectious disease transmission zone identification server (200) can determine indirect contacts of an infectious disease based on the transmission zone. For example, the infectious disease transmission zone identification server (200) can select individuals who entered the zone during the designated transmission zone time period as indirect contacts.

[0099] More specifically, referring to FIG. 8, the infectious disease transmission zone identification server (200) can determine whether a plurality of zones have positive or negative pressure. At this time, when determining the positive or negative pressure of zone D (801), the infectious disease transmission zone identification server (200) can receive the air pressure measured from the space pressure measurement sensor (802) inside zone D (801) and the air pressure measurement sensor (803) outside. Here, the infectious disease transmission zone identification server (200) may determine that the air pressure measured from the internal space pressure measurement sensor (802) is lower than the air pressure measured from the external space pressure measurement sensor (803). At this time, the infectious disease transmission zone identification server (200) can determine that zone D (801) has negative pressure and that air is flowing in from the outside (804).

[0100] Meanwhile, when determining the positive or negative pressure of Zone A (805), the infectious disease transmission zone identification server (200) may receive the air pressure measured from the space pressure measurement sensor (806) inside Zone A (805) and the air pressure measurement sensor (807) outside. Here, the infectious disease transmission zone identification server (200) may determine that the air pressure measured from the internal space pressure measurement sensor (806) is higher than the air pressure measured from the external space pressure measurement sensor (807). At this time, the infectious disease transmission zone identification server (200) may determine Zone A (805) to have positive pressure and that no air is flowing in from the outside.

[0101] At this time, the infectious disease transmission zone identification server (200) can repeatedly determine negative and positive pressures for all first zones connected to the stay zone and air circulation. Here, the infectious disease transmission zone identification server (200) can repeatedly determine negative and positive pressures for the stay zone and the first zone, and then determine the first zone determined to have negative pressure as a transmission zone. In addition, the infectious disease transmission zone identification server (200) can determine to have negative or positive pressure for the second zone connected to the first zone determined as a transmission zone. In addition, the infectious disease transmission zone identification server (200) can expand the transmission zone by determining negative or positive pressures for all zones connected to the zone determined as a transmission zone. For example, the process of determining positive and negative pressure for a first zone connected to a residence zone, determining positive and negative pressure for a second zone connected to the first zone determined as a propagation zone, and determining whether to have positive and negative pressure for a third zone connected to the second zone determined as a propagation zone can be repeated.

[0102] Referring to FIG. 9, the infectious disease transmission zone identification server (200) may provide a user interface depicting transmission zones. At this time, the infectious disease transmission zone identification server (200) may provide a user interface that distinguishes between transmission zones (901) and non-transmission zones (902). As a result, the infectious disease transmission zone identification server (200) may enhance visibility into transmission zones.

[0103] Referring to FIGS. 10 and 11, the infectious disease transmission zone identification server (200) can provide data on the area connected to the stay area and the area that allows air circulation.

[0104] At this time, referring to FIG. 10, the infectious disease transmission zone identification server (200) can receive a space name (1001), a space ID (1002), an atmospheric pressure state (1003), a state change date (1004), a state end date (1005), etc. Here, the space name (1001) may be a name for a zone configured to determine positive or negative pressure. For example, the infectious disease transmission zone identification server (200) may receive the zone name (1001) as Ward 202, Nursing Station. Meanwhile, the space ID (1002) may be an identifier for a zone configured to determine positive or negative pressure. For example, the infectious disease transmission zone identification server (200) may receive the space ID (1002) as D, E. In addition, the atmospheric pressure state (1003) may be a positive or negative pressure determined for each zone. For example, the infectious disease transmission zone identification server (200) can receive the atmospheric pressure status (1003) as negative pressure for zone D and positive pressure for zone E. At this time, the status change date (1004) may be the time when the atmospheric pressure for each zone changes. For example, the infectious disease transmission zone identification server (200) can receive the status change date (1004) as around 11:00 on October 1, 2023. In addition, the status end date (1005) may be the time when the atmospheric pressure for each zone changes to a different atmospheric pressure. For example, the infectious disease transmission zone identification server (200) can receive the status end date (1005) as around 15:00 on October 1, 2023.

[0105] Meanwhile, referring to FIG. 11, the infectious disease transmission zone identification server (200) can receive a space name (1101), a space ID (1102), an atmospheric pressure state (1103), a state change date (1104), a state end date (1105), etc. Here, the space name (1101) may be a name for a zone configured to determine positive pressure or negative pressure. For example, the infectious disease transmission zone identification server (200) may receive the zone name (1101) as Ward 201, a nursing station. Meanwhile, the space ID (1102) may be an identifier for a zone configured to determine positive pressure or negative pressure. For example, the infectious disease transmission zone identification server (200) may receive the space ID (1102) as A, B. In addition, the atmospheric pressure state (1103) may be a positive pressure or negative pressure determined for each zone. For example, the infectious disease transmission zone identification server (200) can receive the atmospheric pressure status (1103) as positive pressure for zone A and negative pressure for zone B. At this time, the status change date (1104) may be the time when the atmospheric pressure for each zone changes. For example, the infectious disease transmission zone identification server (200) can receive the status change date (1104) as around 11:00 on October 1, 2023. In addition, the status end date (1105) may be the time when the atmospheric pressure for each zone changes to a different atmospheric pressure. For example, the infectious disease transmission zone identification server (200) can receive the status end date (1105) as around 15:00 on October 1, 2023.

[0106] In another embodiment, referring to FIG. 12, the infectious disease transmission zone identification server (200) searches for the area where a confirmed patient stayed (S1201). At this time, the infectious disease transmission zone identification server (200) can search for the area where a confirmed patient stayed based on space-specific entry / exit history data.

[0107] Next, the infectious disease transmission zone identification server (200) checks the atmospheric pressure status of the residence area (S1202). At this time, the infectious disease transmission zone identification server (200) can receive spatial pressure measurement history measured from a spatial pressure measurement sensor.

[0108] Next, the infectious disease transmission area identification server (200) determines whether the air pressure of the stay space is negative or positive (S1203).

[0109] As a result of step S1203, if the atmospheric pressure of the residence space is positive, the infectious disease transmission zone identification server (200) searches for a transmission-capable space (S1204). At this time, the infectious disease transmission zone identification server (200) can search for a transmission-capable space connected to the residence space and air circulation based on data including coordinates, identifiers, characteristics, etc. for the space.

[0110] Next, the infectious disease transmission zone identification server (200) checks the atmospheric pressure status of the transmission-capable space (S1205). At this time, the infectious disease transmission zone identification server (200) can receive spatial pressure measurement history measured from a spatial pressure measurement sensor.

[0111] Next, the infectious disease transmission zone identification server (200) determines whether the air pressure in the transmission-prone space is negative or positive (S1206). At this time, the infectious disease transmission zone identification server (200) can determine whether the air pressure in the transmission-prone space is negative or positive based on whether the air pressure is relatively higher or lower than the air pressure in the residence space.

[0112] As a result of step S1206, if the pressure in the transmission-capable space is negative, the infectious disease transmission zone identification server (200) adds a contact investigation space (S1207).

[0113] As a result of step S1206, if the pressure of the transmission-capable space is positive and after adding the contact investigation space, the infectious disease transmission area identification server (200) repeatedly executes steps S1206 and S1207 for all transmission-capable spaces (S1208).

[0114] Next, the infectious disease transmission area identification server (200) adds a contact investigation space to the space where a confirmed patient stayed (S1209).

[0115] Next, the infectious disease transmission zone identification server (200) identifies entrants to the contact investigation space (S1210). At this time, the infectious disease transmission zone identification server (200) can identify entrants to the space where contact investigation is being conducted based on space-specific entry / exit history data.

[0116] As another example, the infectious disease transmission zone identification server (200) may receive air conditioning system data for the zone. The air conditioning system data may be data regarding variables that may affect air flow, including heating, ventilation, and air conditioning. Here, the infectious disease transmission zone identification server (200) may determine air flow between spaces based on the air conditioning system data.

[0117] For example, when air flows from zone A to zone B due to an air conditioning system, the infectious disease transmission zone identification server (200) can determine zone B as a retention zone or transmission zone if zone A is determined to be a retention zone or transmission zone.
