Description

The present invention relates to a facility management system that manages a facility having multiple sections.

In general, security management for facility entry and exit is implemented by authenticating information that identifies individuals, but for example, in certain rooms (sections) such as biochemical laboratories and hospital facilities, even if a user has the authority to enter, if they are infected with a pathogen such as influenza, they are prohibited from entering the room (Patent Document 1).

In the case of infectious diseases caused by pathogens such as influenza, there is an incubation period for the pathogen that causes the disease. Therefore, people who come into contact with an infected person during the incubation period may already be infected. With conventional technology, people who are at risk of infection are restricted from entering the room.

JP 2019-200503 A

However, with the above-mentioned technology, even if a person is in a large room with an infected person and is actually far enough away that the risk of infection is low, or even if the person was in the same room for only a few seconds and therefore the risk of infection is low, the technology described above will determine that there is a risk of infection. For this reason, the above-mentioned conventional technology may excessively hinder the use of facilities. In addition, because the degree of infection, symptoms, and severity of symptoms vary depending on the type of pathogen, if a person is uniformly determined to be at risk of infection, this will excessively restrict people's activities.

The present invention was made to solve the above problems, and aims to manage the entry and exit of infected persons without excessively interfering with the use of the facility.

The facility management system according to the present invention includes a first storage unit configured to store, for each of the multiple sections, user information identifying a user who uses multiple sections that are managed within a facility; a management unit configured to manage the location of a user identified by the user information in each of the multiple sections based on authentication information based on the user information; a second storage unit configured to store a location history in each of the multiple sections of a user whose location is managed by the management unit together with the user information; a reception unit configured to receive first user information identifying a first user who has been determined to be infected and an infection status including information on the day the first user became infected; and a reception unit configured to retrieve from the second storage unit a first history of the multiple sections in which the first user has been present from the day the first user became infected to the present based on the first user information and infection status received by the reception unit. the second acquisition unit configured to acquire from the second memory unit second user information of a second user who coexisted in the same partition as the first user during a first period specified in the first history, together with information of the partition in which the second user coexisted with the first user; a calculation unit configured to calculate a coexistence time during which the second user coexisted in the same partition as the first user; a third memory unit configured to store coexistence information including information of the partition in which the second user coexisted with the first user and the coexistence time, together with the second user information; a fourth memory unit configured to store a coexistence condition to be excluded as an exclusion condition; a selection unit configured to select, from the second user information, third user information having coexistence information that does not match the exclusion condition; and an output unit configured to output the third user information as a contact of the first user.

In one example configuration of the facility management system described above, the fourth memory unit stores at least one of information about the section designated for exclusion and the exclusion time range as exclusion conditions.

In one example configuration of the facility management system described above, the output unit outputs the second user information in addition to the third user information.

In one configuration example of the facility management system, a card reader is installed in each of the multiple sections and configured to read card information stored on an IC card owned by a user, and the management unit manages the location of a user identified by the user information in each of the multiple sections based on authentication information obtained by matching or mismatching the card information read by the card reader with the user information.

In one configuration example of the facility management system, a biometric information acquisition unit is installed in each of the multiple sections and acquires biometric information of users, and the management unit manages the location of users identified by the user information in each of the multiple sections based on authentication information obtained by a match or mismatch between the biometric information acquired by the biometric information acquisition unit and the user information.

In one configuration example of the facility management system, a receiving unit is provided that is configured to receive terminal information transmitted from a terminal owned by a user via wireless communication and measure the position of the terminal that received the terminal information, and the management unit manages the location of the user identified by the user information in each of multiple sections based on authentication information resulting from a match or mismatch between the terminal information received by the receiving unit and the user information at the terminal position measured by the receiving unit.

In one example configuration of the above facility management system, the third storage unit stores the coexistence time with a weight corresponding to the length of the coexistence time.

In one example configuration of the facility management system described above, the coexistence time is stored with a weight corresponding to the area of the section.

As described above, according to the present invention, third user information having coexistence information that does not match the exclusion condition is selected from among second users who coexisted with a first user who has been determined to be infected, so that entry and exit of infected people can be managed without excessively interfering with the use of the facility.

The following describes a facility management system according to an embodiment of the present invention.

[First embodiment]
First, a facility management system according to a first embodiment of the present invention will be described with reference to Fig. 1. This facility management system includes a first storage unit 101, a management unit 102, a second storage unit 103, a reception unit 104, a first acquisition unit 105, a second acquisition unit 106, a calculation unit 107, a third storage unit 108, a fourth storage unit 109, a selection unit 110, and an output unit 111.

The first storage unit 101 stores user information for each of the multiple sections that identify users who use the multiple sections that are managed within the facility. The management unit 102 manages the location of the users identified by the user information in each of the multiple sections based on authentication information from the user information. The management unit 102 also has a well-known entrance and exit management function.

In the first embodiment, the facility management system includes a card reader 112 that reads card information stored on an IC card owned by a user. The card reader 112 is installed in each of the multiple sections. The management unit 102 manages the location of a user identified by user information in each of the multiple sections based on authentication information obtained by a match or mismatch between the card information read by the card reader 112 and the user information.

For example, if the card information read by the card reader 112 matches the user information, the management unit 102 allows the user to enter the corresponding area. The management unit 102 manages the user's location in the area by recording the state in which the user has been allowed to enter the corresponding area in this way. Note that, for example, if the card information read by the card reader 112 does not match the user information, the management unit 102 restricts the user from entering the corresponding area.

The second storage unit 103 stores the location history of the user in each of the multiple sections whose location is managed by the management unit 102 together with the user information. The reception unit 104 receives the first user information identifying the first user who is determined to be infected, and the infection status including information on the day of infection. The first acquisition unit 105 acquires from the second storage unit 103 the history (first history) of the multiple sections in which the first user was present from the day the first user was infected to the present, based on the first user information and infection status received by the reception unit 104.

The second acquisition unit 106 acquires from the second storage unit 103 second user information of a second user who coexisted in the same section as the first user during a first period specified by the acquired first history, together with information on the section in which the second user coexisted with the first user. The calculation unit 107 calculates the coexistence time during which the second user coexisted in the same section as the first user.

The third storage unit 108 stores coexistence information including information on the section where the first user coexisted with the first user and the coexistence time together with the second user information. The fourth storage unit 109 stores the coexistence conditions to be excluded as exclusion conditions. The fourth storage unit 109 stores at least one of the information on the section specified for exclusion and the exclusion time range as exclusion conditions.

The coexistence time stored in the third storage unit 108 can also be ranked by weighting. For example, the third storage unit 108 can store the coexistence time with a weight corresponding to the length of the coexistence time. As an example, if the coexistence time is 30 minutes or less, the weight can be 50, if the coexistence time is 30 minutes or more and 1 hour or less, the weight can be 70, and if the coexistence time is 1 hour or more, the weight can be 100. The third storage unit 108 can also store the coexistence time with a weight corresponding to the size of the section. If coexistence occurs in a small section, the degree of contact is high, so if coexistence occurs in a small section, the weight can be, for example, 1.5 times, and if coexistence occurs in a large section, the weight can be 0.5 times.

The selection unit 110 selects, from the second user information stored in the third storage unit 108, third user information having coexistence information that does not match the exclusion condition stored in the fourth storage unit 109. The output unit 111 outputs the third user information as a contact of the first user. The output unit 111 is, for example, a display device, and displays the first user information as an infected person, and displays the third user information as a contact who has been in contact with an infected person. The output unit 111 can also output the second user information in addition to the third user information.

For example, a facility user feels unwell, goes to a hospital for a checkup, and is found to be infected with the virus as a result, thereby realizing that he or she is infected. The user also recognizes how long the user has been infected from hearing about symptoms, etc. This user notifies information such as that he or she has been infected and how long the infection has been present. For example, if the user is an employee of a company that is leasing the facility, the user will notify the company to which he or she belongs of the user's infection status as described above. The company staff member who receives this notification enters the user information of the relevant user and information such as the infection status as described above into the input unit 113.

When the user information and infection status of the infected user are input to the input unit 113, they are accepted by the acceptance unit 104. When the user information and infection status of the infected user are accepted by the acceptance unit 104, the first acquisition unit 105 acquires from the second storage unit 103 a first history indicating in which section the first user has been present from the day the infected first user became infected to the present, based on the accepted user information (first user information) and infection status.

When the first acquisition unit 105 acquires the first history, the second acquisition unit 106 acquires, from the second storage unit 103, second user information of the second user who coexisted in the same partition as the first user during the first period identified in the first history. The second acquisition unit 106 acquires the second user information together with information on the partition in which the second user coexisted with the first user. In addition, when the first acquisition unit 105 acquires the first history, the calculation unit 107 calculates the coexistence time during which the second user coexisted in the same partition as the first user based on the information on the first period described above.

When a first user becomes infected, a second user who coexists in one of the sections may also become infected. However, if the section in which they coexist is large and the first and second users are sufficiently far apart, it can be determined that the risk of infection is low. Also, if the first and second users coexist for only a few seconds, it can also be determined that the risk of infection is low. Therefore, large sections are designated as excluded, and an exclusion time range is set to, for example, 3 seconds or less, and the selection unit 110 excludes second users whose coexistence information matches these exclusion conditions, and the remaining excluded second users are designated as third users.

As described above, information on the third user selected by the selection unit 110 is displayed as a person who has come into contact with an infected person, along with information on the infected person. The management unit 102 restricts entry to the facility of infected people and users who may have come into contact with infected people. The management unit 102 can also issue an alert when an infected person is found.

As described above, according to the first embodiment, third user information having coexistence information that does not match the exclusion condition is selected from among the second users, so that the entry and exit of infected persons can be managed without excessively interfering with the use of the facility.

[Embodiment 2]
Next, a facility management system according to a second embodiment of the present invention will be described with reference to Fig. 2. This facility management system includes a first storage unit 101, a management unit 102, a second storage unit 103, a reception unit 104, a first acquisition unit 105, a second acquisition unit 106, a calculation unit 107, a third storage unit 108, a fourth storage unit 109, a selection unit 110, an output unit 111, and an input unit 113. These components are similar to those in the first embodiment described above.

In the second embodiment, the facility management system includes a biometric information acquisition unit 114 that acquires biometric information of users. The biometric information acquisition unit 114 is installed in each of the multiple sections. The management unit 102 manages the location of the user identified by the user information in each of the multiple sections based on authentication information resulting from a match or mismatch between the biometric information acquired by the biometric information acquisition unit 114 and the user information.

For example, if the biometric information acquired by the biometric information acquisition unit 114 matches the user information, the management unit 102 permits entry into the corresponding area. The management unit 102 manages the user's location in the area by recording the state in which the user has been permitted to enter the corresponding area in this manner. Note that, for example, if the biometric information acquired by the biometric information acquisition unit 114 does not match the user information, the management unit 102 restricts entry into the corresponding area.

The biometric information acquisition unit 114 may be configured, for example, from a fingerprint sensor. In this case, the biometric information acquisition unit 114 acquires a fingerprint image of the user as biometric information. The biometric information acquisition unit 114 may be configured from a face recognition device. In this case, the biometric information acquisition unit 114 acquires an image of the user's face as biometric information. The biometric information acquisition unit 114 may be configured from a sensor that captures an image of the vein shape. In this case, the biometric information acquisition unit 114 acquires an image of the vein shape pattern (vein image) under the skin of the user's finger as biometric information. The biometric information acquisition unit 114 may be configured from a sensor that measures the pattern of the iris or retina. In this case, the biometric information acquisition unit 114 acquires the pattern of the iris or retina of the user's eye as biometric information.

In the second embodiment, as in the first embodiment described above, third user information having coexistence information that does not match the exclusion condition is selected from among the second users, so that the entry and exit of infected persons can be managed without excessively interfering with the use of the facility.

[Embodiment 3]
Next, a facility management system according to a third embodiment of the present invention will be described with reference to Fig. 3. This facility management system includes a first storage unit 101, a second storage unit 103, a reception unit 104, a first acquisition unit 105, a second acquisition unit 106, a calculation unit 107, a third storage unit 108, a fourth storage unit 109, a selection unit 110, and an output unit 111. These components are similar to those in the first embodiment described above.

In the third embodiment, a receiver 115 is provided that receives terminal information transmitted from a terminal owned by a user via wireless communication and measures the location of the terminal that received the terminal information. The receiver 115 establishes communication with the terminal via, for example, a wireless LAN. The receiver 115 can also communicate with the terminal via short-range wireless communication such as "Bluetooth" (trademark) or "ZigBee" (trademark).

In the third embodiment, the management unit 102a manages the location of a user in each of a plurality of sections, the user being identified by the user information, based on authentication information resulting from a match or mismatch between the terminal information and user information received by the receiving unit 115 at the terminal position measured by the receiving unit 115. The management unit 102a has a well-known entrance and exit management function. For example, the management unit 102a manages the location of the user in a section by recording the section in which the user is present over time, based on the position information of the terminal from which the receiving unit 115 received the terminal information.

In the third embodiment, as described above, the location history of the user in each of the multiple sections managed by the management unit 102a is stored in the second storage unit 103 together with the user information. When recording the sections in which the user is present over time, the amount of recorded information may increase and exceed the processing capacity. In such a case, the terminal may record its location and accept this information for a limited period of time.

In the third embodiment, similarly to the above, when the user information and infection status of an infected user are input to the input unit 113 and accepted by the acceptance unit 104, the first acquisition unit 105 acquires from the second storage unit 103 a first history indicating in which section the first user has been present from the day the infected first user became infected to the present.

When the first acquisition unit 105 acquires the first history, the second acquisition unit 106 acquires, from the second storage unit 103, second user information of the second user who coexisted in the same partition as the first user during the first period specified in the first history. The second acquisition unit 106 acquires the second user information together with information on the partition in which the second user coexisted with the first user. In addition, when the first acquisition unit 105 acquires the first history, the calculation unit 107 calculates the coexistence time during which the second user coexisted in the same partition as the first user based on the information on the first period described above.

The selection unit 110 also excludes second users having coexistence information that matches the exclusion conditions stored in the fourth storage unit 109, and the remaining excluded second users are regarded as third users. In the third embodiment as well, information on the third users selected by the selection unit 110 is displayed as those who have come into contact with the infected person, along with information on the infected person. The management unit 102a restricts entry to the facility of infected people and users who may have come into contact with infected people. The management unit 102a can also issue an alert when an infected person is identified.

As shown in FIG. 4, the facility management system according to the above-described embodiment can be a computer device equipped with a CPU (Central Processing Unit) 301, a main memory device 302, an external memory device 303, a network connection device 304, etc., and each of the above-described functions can be realized by the CPU 301 operating (executing the program) according to a program deployed in the main memory device 302. The network connection device 304 is connected to a network 305. Also, each function can be distributed among multiple computer devices.

As described above, according to the present invention, third user information having coexistence information that does not match the exclusion condition is selected from among second users who coexisted with a first user who has been determined to be infected, making it possible to manage the entry and exit of infected people without excessively interfering with the use of the facility.

The present invention is not limited to the embodiments described above, and it is clear that many modifications and combinations can be implemented by those with ordinary skill in the art within the technical concept of the present invention.
