DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this specification and drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant description will be omitted.

[0017] The matters described in this embodiment are all examples of embodiments of the present invention, and the technical scope of the present invention is not limited thereto. Furthermore, the building management system, user terminal 100, administrator terminal 200, building management server 300, information provision method, and program described in this embodiment can all be appropriately modified in terms of their decentralized and centralized aspects. Each of the matters described in this embodiment is an optional additional matter, and the present invention can be implemented by combining or omitting each technical matter as appropriate.

[0018] (Outline of the embodiment) The building management system according to this embodiment is used in buildings such as apartment complexes, condominiums, apartment buildings, or commercial buildings. Specifically, the building management system according to this embodiment is used by users U, such as building compartment owners, residents, people leasing rooms, or people renting rooms, and building managers M, such as the management association, management association officers, management company, or employees of the management company that manages the building, and is used to share information between users U and building managers M.

[0019] FIG. 1 is a diagram showing the network configuration of a building management system according to this embodiment. As shown in FIG. 1 , the building management system according to this embodiment includes a user terminal 100 used by a user U, such as a condominium owner or resident of a building; an administrator terminal 200 used by a building manager M, such as a building management association, an officer of the management association, a management company, or an employee of the management company; and a building management server 300 connected to the user terminal 100 and the administrator terminal 200 via a communication line. As an example, this embodiment illustrates an example in which the user terminal 100, the administrator terminal 200, and the building management server 300 are each connected to a network N, thereby enabling the user terminal 100, the administrator terminal 200, and the building management server 300 to transmit and receive information to and from each other. However, the building management system requires that the building management server 300 be connected to the user terminal 100 and the administrator terminal 200 via a communication line; it does not require the user terminal 100 and the administrator terminal 200 to be connected to a common network N so that they can transmit and receive information without going through the building management server 300.

[0020] As shown in FIG. 1 , in the building management system according to this embodiment, three user terminals 100 used by multiple users U in one building, ABC Mansion, and two administrator terminals 200 used by multiple building managers M in ABC Mansion, as well as one user terminal 100 used by users U in another building, XYZ Heim, and one administrator terminal 200 used by the building manager M in YYZ Heim, are connected to a network N, and one building management server 300 is also connected to the network N. However, the numbers of user terminals 100, administrator terminals 200, and building management servers 300 constituting the building management system can be changed as appropriate. That is, with respect to the user terminals 100 used by a user U, a single user U may use multiple user terminals 100, or multiple users U may each use one or multiple user terminals 100. Furthermore, with respect to the administrator terminal 200 used by a building manager M, a single building manager M may use multiple administrator terminals 200, or multiple building managers M may each use one or multiple administrator terminals 200. The building management server 300 may be configured as a single computer, or may be configured as a combination of multiple computers. Furthermore, the building management server 300 may manage information about multiple buildings by a single building management server 300, or a building management server 300 may be provided for each building so that information about one building is managed by a single building management server 300. The building management server 300 may be managed by a server administrator S who manages the servers, or may be managed by a building administrator M.

[0021] The building management system according to this embodiment may be configured as a three-tier client-server system, for example. That is, the building management server 300 may be configured with a presentation layer that sends and receives information to and from the user terminal 100 and the administrator terminal 200, an application layer that processes system-related tasks, and a data layer that manages data used for processing by the application layer. In this case, most of the processing of the building management system according to this embodiment can be performed by the building management server 300, reducing the processing load on the user terminal 100 and the administrator terminal 200 and facilitating application execution and data management.

[0022] Furthermore, the building management server 300 according to this embodiment may have an authentication layer independent of the presentation layer, application layer, and data layer to ensure the authenticity of the user terminal 100 or the administrator terminal 200. In this case, the independence between the processing in the presentation layer and application layer and the processing for authenticating the user terminal 100 or the administrator terminal 200 can be increased, making it possible to protect information more reliably than before.

[0023] To provide an overview of the processing of the building management system according to this embodiment, the building management server 300 receives and stores, from the user terminal 100 and the administrator terminal 200, contact information that is a message from user U to building manager M and notification information that is a notice from building manager M to user U. The building management server 300 then acquires selected contact information, which is information from the contact information that should be displayed on the user terminal 100 that sent the information. The building management server 300 then transmits the selected contact information and the notification information to the user terminal 100 that sent the contact information. The user terminal 100 then displays the contents of the selected contact information and the notification information on the display unit 102. Through the above processing, the building management system according to this embodiment makes it easy for user U to check the contact from user U to building manager M and the notice from building manager M to user U.

[0037] The main memory unit 205a can be configured by a temporary storage area such as a static random access memory (SRAM), a dynamic random access memory (DRAM), a cache memory, a flash memory, or a combination of these. The main memory unit 205a temporarily stores data necessary for the control unit 201 to perform various arithmetic processing.

[0038] The auxiliary storage unit 205b can be configured, for example, by a non-volatile storage area such as a hard disk drive (HDD) or a solid state drive (SSD), or a combination of these. The auxiliary storage unit 205b stores programs and data necessary for the control unit 201 to execute processing, as well as other programs and data. More specifically, the auxiliary storage unit 205b stores, for example, a program for the manager terminal 200 in a building management system.

[0039] 3, as an example, the building management server 300 includes a control unit 301, a display unit 302, an input unit 303, a communication unit 304, and a main memory unit 305a and an auxiliary memory unit 305b that constitute a memory unit 305.

By connecting the building management server 300 to the network N, the communication unit 304 enables transmission and reception of information between the building management server 300 and the user terminal 100 and the administrator terminal 200.

[0044] The main memory unit 305a can be configured by a temporary storage area such as a static random access memory (SRAM), a dynamic random access memory (DRAM), a cache memory, a flash memory, or a combination of these. The main memory unit 305a temporarily stores data required for the control unit 301 to perform various arithmetic processing.

[0045] The auxiliary storage unit 305b can be configured, for example, by a non-volatile storage area such as a hard disk drive (HDD) or a solid state drive (SSD), or a combination of these. The auxiliary storage unit 305b stores programs and data necessary for the control unit 301 to execute processes, as well as other programs and data. More specifically, the auxiliary storage unit 305b stores, for example, programs for the building management server 300 in a building management system. As shown in FIG. 3, the auxiliary storage unit 305b also stores client information, contact information, usage reservation information included in the contact information, notice information, and safety information.

[0046] Examples of client information, contact information, reservation information included in the contact information, and notice information will be described below with reference to Fig. 4 and Fig. 5. Fig. 4 is a diagram showing client information according to an embodiment, and shows, as an example, a user U table that holds information about a user U and a building manager M table that holds information about a building manager M. Fig. 5 is a diagram showing contact information, notice information, and safety information according to an embodiment. In this embodiment, a configuration in which data is stored in a table format is described as an example, but the configuration in which data is stored is not limited to this. For example, data may be stored in an appropriately normalized relational database as shown in this embodiment, or in a NoSQL database having another tree structure or network structure.

[0047] The client information includes information about the user U and the building manager M, and is used to identify the sender of various information received from the user terminal 100 and the manager terminal 200, as well as to identify the building to which the information relates.

[0048] It is preferable that the information about user U includes at least information that identifies one user U and information that identifies the building that user U owns or resides in. The information that identifies one user U enables the building management server 300 to identify the user U who uses the user terminal 100 that sent the contact information, etc. Furthermore, the information that identifies the building that user U owns or resides in enables the building management server 300 to identify which building the information received from a specific user terminal 100 relates to.

[0049] As shown in the user U table in FIG. 4, the information about user U among the client information can include attributes such as a client ID, name, building ID, building name, room number, and address. The client ID represents an ID that uniquely identifies user U, and can be used as a key when associating information with other tables. The name represents user U's own name, or the name if user U is a corporation or other organization. The building ID represents an ID that uniquely identifies a building, and can be used as a key when associating information with other tables. The building name represents the name of the building that user U owns or resides in. The room number represents the number of the room that user U owns or resides in. The address represents user U's address.

[0050] It is preferable that the information on the building manager M includes at least information identifying one building manager M and information identifying the building managed by the building manager M. The information identifying one building manager M enables the building management server 300 to identify the building manager M who uses the manager terminal 200 that sent the notification information, etc. Furthermore, the information identifying the building managed by the building manager M enables the building management server 300 to identify which building the information received from a specific manager terminal 200 relates to.

[0051] As shown in the building manager M table in FIG. 4, the information on the building manager M among the client information can be configured to include attributes such as a client ID, a name, a building ID, a building name, and an address. The client ID represents an ID that uniquely identifies the building manager M, and can be used as a key when relating information with other tables. The name represents the name of the building manager M himself, or the name if the building manager M is a corporation or other organization. The building ID represents an ID that uniquely identifies the building, and can be used as a key when relating information with other tables. The building name represents the name of the building managed by the building manager M. The address represents the address of the building managed by the building manager M.

[0052] Furthermore, it is preferable that a user U of a predetermined building and a building manager M of the predetermined building are stored in association with each other. As an example, as shown in FIG. 4, by using a building ID included in the user U table and a building ID included in the building manager M table as a common ID, the user U of a predetermined building and the building manager M of the predetermined building can be stored in association with each other via the building ID. Also, for example, the user U table may be provided with a column containing information identifying the building manager M who manages the building of the predetermined user U, and the building manager M table may be provided with a column containing information identifying the user U of a building managed by the predetermined building manager M. In this case, information such as notification information sent by the administrator terminal 200 used by the building manager M associated with the user U can be transmitted to the user terminal 100 used by the user U of a specific building. Similarly, information such as contact information sent by the user terminal 100 used by the user U associated with the building manager M can be transmitted to the administrator terminal 200 used by the building manager M of the specific building. This makes it possible to manage and share information with a specific building as the management unit.

[0053] Furthermore, it is preferable that a user U in a specific building and another user U in the same specific building are stored in association with each other. As an example, in FIG. 4, if the building ID included in the record of the user U is the same as the building ID included in the record of the other user U, the user U and the other user U are stored in association with each other as users U in the same building via the building ID. Also, for example, the user U table may be provided with a column containing information identifying the other user U associated with the same building as the user U.

[0054] The name, building name, or address attributes included in the User U table and the Building Manager M table are partially or transitively functionally dependent on other attributes. For this reason, normalization may be performed by separating the name, building name, or address attributes into separate tables. Alternatively, for example, the User U table and the Building Manager M table may be combined into a single table, with an additional attribute added to identify whether a given client is a user U or a building manager M.

[0055] The contact information is a message from the user U to the building manager M, and includes a message content indicating the content of the message, a message type indicating the type according to the message content, and a message-related date indicating a date related to the message content. As shown in Fig. 5, as an example, the contact information in this embodiment is configured to include attributes of a client ID, a received date and time, a message content, a message type, and a message-related date. The client ID in the contact information is the same as the client ID in the client information, and enables identification of the user U using the user terminal 100 that sent the contact information in a specified record. The reception date and time indicates the date and time when the building management server 300 received the contact information in a specified record. The contact content indicates the content of the contact entered by the user U using the input unit 103 of the user terminal 100. The contact type indicates a type according to the contact content, and various types can be set as necessary. The contact-related date indicates a date related to the contact content; for example, if the contact content is regarding a repair request, it can be the desired date for the repair, and if the contact content is regarding the reservation of equipment such as facilities or fixtures, it can be the desired date for the equipment to be reserved.

[0056] Furthermore, various types of communication content can be adopted as long as it represents the content of the communication from user U to building manager M. As for communication content from user U to building manager M regarding matters related to the condominium, a wide range of communication content can be envisioned, such as reports and communications on various matters, submission of prescribed documents, and prescribed applications. Note that the communication content may be, for example, a message created by user U inputting characters by operating the input unit 103 of the user terminal 100, or may be created by user U selecting communication content from options representing candidates for prescribed communication content. In this embodiment, an example of using a chatbot to prompt user U to input and accept the input of communication content will be described later. Furthermore, various types of contact types can be adopted as long as they represent a type according to the content of the contact. As long as the contact type is used to classify various types of contact content into a predetermined number of types of contact, various types such as proposals, agenda requests, troubles, repair requests, cleaning requests, and responses to unauthorized parking can be provided. For example, the contact type may be selected by the user U from a selection of contact types, may be assigned by analyzing the message of the contact content, or may be determined according to the input screen of the contact content on the user terminal 100. In this embodiment, an example in which the contact type is determined according to the interaction between the chatbot and the user U will be described below as an example. Furthermore, various types of communication-related dates can be used as long as they represent dates related to the content of the communication. Various dates can be used as communication-related dates, such as past dates that you want to keep in your records, future scheduled dates, deadlines for submitting various documents, etc. Note that the communication-related date can be obtained automatically from a date embedded in the message of the content of the communication, or by prompting the user U to input a date.

[0057] The notification information is a notification from the building manager M to the user U, and includes notification content indicating the content of the notification and a notification-related date indicating a date related to the notification content. As shown in Fig. 5, as an example, the notification information in this embodiment is configured to include a client ID, a reception date and time, notification content, notification type, and a notification-related date. The client ID in the notification information is the same as the client ID in the client information, and enables identification of the building manager M using the manager terminal 200 that sent the notification information in a specified record. The reception date and time indicates the date and time when the building management server 300 received the notification information in a specified record. The notification content indicates the content of the notification entered by the building manager M using the input unit 203 of the manager terminal 200. The notification type indicates a type according to the notification content, and various types can be set as necessary. The notification-related date indicates a date related to the notification content; for example, if the notification content is about a waterworks inspection, it can be the date on which the waterworks inspection will be carried out, and if the notification content is about recruiting specified volunteers, etc., it can be the date on which the volunteer activity will be carried out.

[0058] Furthermore, the notification content can take various forms as long as it represents the content of the notification from the building manager M to the user U. As the notification content, a wide range of reports, contacts, notifications, guidance, etc. can be envisioned, as long as it is a communication from the building manager M to the user U about matters related to the condominium. Note that the notification content may be, for example, a message created by the building manager M inputting characters by operating the input unit 203 of the manager terminal 200, or may be created by the building manager M selecting notification content from options representing candidates for predetermined notification content. Furthermore, various notification types can be adopted as long as they represent a type according to the notification content. As notification types, various types such as apartment notifications, construction notifications, and local notifications can be provided as long as they are used to classify various notification contents into a predetermined number of notification types. Note that, for example, the notification type may be selected by the building manager M from a selection of notification types, may be assigned by analyzing the message of the notification content, or may be determined according to an input screen of the notification content on the manager terminal 200. Furthermore, various types of notification-related dates can be used as long as they represent dates related to the notification content. Notification-related dates can be various dates such as past dates that you want to keep in your records, future scheduled dates, deadlines for submitting various documents, etc. Note that notification-related dates can be obtained automatically from dates embedded in the message of the notification content, or by prompting the building manager M to input a date.

[0059] The safety information is information indicating the safety of the user U. As shown in Fig. 5, as an example, the safety information in this embodiment includes a client ID, a reception date and time, safety, location, and a message. The client ID in the safety information is the same as the client ID in the client information, and makes it possible to identify the user U or building manager M using the user terminal 100 or manager terminal 200 that sent the safety information in a specified record. The reception date and time indicates the date and time when the safety information in a specified record was received. Safety indicates the safety of user U or building manager M through information such as safe or in need of help. Location indicates the location of user U or building manager M through information such as at home or out. The message indicates a specified message entered by user U or building manager M. In addition, information regarding safety or whereabouts may be input by the user U or building manager M selecting the safety or whereabouts status from predetermined options, or may be input as text by the user U or building manager M. Similarly, the message may be input as text by the user U or the building manager M, or may be input by the user U selecting a message from a selection of predetermined messages.

[0060] (Each function in the embodiment and its relationship) Next, we will explain the functions of the building management system realized by the hardware elements of the user terminal 100, administrator terminal 200, and building management server 300 of the building management system in this embodiment, as well as the programs stored in them, and the interrelationships between these functions. FIG. 6 is a diagram showing the functional relationships of the building management system according to the embodiment.

[0061] 6, the user terminal 100 includes a contact information receiving means 111, a user-side transmission means 112, a usage reservation means 113, a user-side display means 114, and a safety confirmation means 115, which are configured by its hardware elements and programs stored in the memory unit 105. The manager terminal 200 includes a notice information receiving means 211 and a manager-side transmission means 212, which are configured by its hardware elements and programs stored in the memory unit 205. The building management server 300 includes a server-side storage means 311, a selected contact information acquisition means 312, a server-side transmission means 313, a safety information receiving means 314, and a safety information transmission means 315, which are configured by its hardware elements and programs stored in the memory unit 305.

[0062] The contact information receiving means 111 is configured by, for example, the control unit 101 and the input unit 103 of the user terminal 100. The contact information receiving means 111 receives input of contact information from a user U to a building manager M, including contact content indicating the content of the contact, a contact type indicating a type according to the contact content, and a contact-related date indicating a date related to the contact content. The contact information receiving means 111 may, for example, receive contact information input by the user U and store the contact information in the storage unit 105 of the user terminal 100 at least temporarily. Such contact information receiving means 111 may be configured to receive input of the matters that the user U wishes to contact the building manager M about, via the input unit 103 such as a touch panel or keyboard of the user terminal 100, for example.

[0063] It should be noted that the contact information receiving means 111 does not need to receive all of the inputs of the contact content, contact type, and contact-related date through the operation of the user U. For example, the contact type or contact-related date may be automatically recognized by analyzing the contact content represented by a predetermined message input by the user U. Also, for example, the contact type may be recognized based on the type of page on which the user U inputs the predetermined message. For this reason, for example, if the user U inputs a message from a trouble report page, the contact type may be recognized as trouble. Furthermore, the contact information receiving means 111 is not required to accept input of information including the contact content, contact type, and contact-related date for all information entered by the user U that represents a contact from the user U to the building manager M. In other words, as long as the contact information receiving means 111 can accept input of contact information including the contact content, contact type, and contact-related date, it does not matter whether or not it accepts input of other information.

[0064] The user side transmission means 112 is configured by, for example, the control unit 101 and the communication unit 104 of the user terminal 100 . The user side transmission means 112 transmits the contact information to the building management server 300 . The user side transmission means 112 can be configured, for example, so that the control unit 101 and the communication unit 104 work together to read out the contact information received by the contact information receiving means 111 from the memory unit 105 and transmit it to the building management server 300.

[0065] The usage reservation means 113 is configured by, for example, the control unit 101, the input unit 103, and the communication unit 104 of the user terminal 100. The usage reservation means 113 accepts input of usage reservation information in which the content of the communication is a reservation for use of a specified facility from a user U to a building manager M, the type of communication indicating that the content of the communication is a usage reservation is the communication type, and the date on which the specified facility will be used is the communication related date, and transmits the usage reservation information to the building management server 300. The use reservation means 113 receives input of use reservation information by the user U, for example, through cooperation between the control unit 101, the input unit 103, and the communication unit 104. The use reservation means 113 receives, for example, the use reservation information input by the user U, and stores the use reservation information at least temporarily in the memory unit 105 of the user terminal 100. The use reservation means 113 reads out, for example, the use reservation information stored in the memory unit 105, and transmits it to the building management server 300. Such a usage reservation means 113 can be configured, for example, to accept input of usage reservation details by the user U using an input unit 103 such as a touch panel or keyboard of the user terminal 100, and to transmit the usage reservation information to the building management server 300 using a communication unit 104.

[0066] The notice information receiving means 211 is configured by, for example, the control unit 201 and the input unit 203 of the administrator terminal 200 . The notification information receiving means 211 receives input of notification information that is a notification from the building manager M to the user U, and that includes notification content indicating the content of the notification and notification-related dates indicating dates related to the notification content. For example, the notification information may further include a notification type indicating a type according to the notification content. The notification information receiving means 211 may, for example, be configured to receive input of notification information by the building manager M through cooperation between the control unit 201 and the input unit 203, and store the notification information at least temporarily in the memory unit 205 of the manager terminal 200. Such notice information receiving means 211 may be configured to receive input of information that the building manager M wishes to notify the user U of via an input unit 203 such as a touch panel or keyboard of the manager terminal 200, for example.

[0067] It should be noted that the notice information receiving means 211 does not need to receive all inputs of the notice content, notice type, and notice-related date through operation by the building manager M. For example, the notice type or notice-related date may be automatically recognized by analyzing the notice content represented by a predetermined message input by the building manager M. Also, for example, the notice type may be recognized based on the page on which the building manager M inputs the predetermined message. For this reason, for example, if the building manager M inputs a message from a page for inputting condominium notices, the notice type may be recognized as a condominium notice.

[0068] The administrator-side transmission means 212 is configured by, for example, the control unit 201 and the communication unit 204 of the administrator terminal 200 . The manager-side transmission means 212 transmits the notification information to the building management server 300. The administrator side transmission means 212 can be configured, for example, so that the control unit 201 and the communication unit 204 work together to read out the notification information received by the notification information receiving means 211 from the memory unit 205 and transmit it to the building management server 300.

[0069] The server-side storage means 311 is configured by, for example, the control unit 301, communication unit 304, and storage unit 305 of the building management server 300. The server-side storage means 311 stores the contact information received from the user terminal 100 and the notification information received from the administrator terminal 200 in the storage unit 305. In addition, for example, the server-side storage means 311 receives usage reservation information from the user terminal 100 as a type of contact information, and stores the usage reservation information in the storage unit 305. The server-side storage means 311 can be configured, for example, so that the control unit 301 and the communication unit 304 work together to receive contact information from the user terminal 100 and notification information from the administrator terminal 200 at appropriate times, and store the received contact information and notification information in the storage unit 305.

[0070] The selected contact information acquisition means 312 is configured by, for example, the control unit 301 and storage unit 305 of the building management server 300 . The selected contact information acquisition means 312 acquires, from the storage unit 305, selected contact information that is information to be displayed on the user terminal 100 of the sender of the contact information, based on the contact type. The selected contact information acquisition means 312 can be configured, for example, to store in advance contact types indicating types according to the contact content that should be displayed on the sender's user terminal 100, and the control unit 301 can search for and acquire contact information including the pre-stored contact types from the storage unit 305. Alternatively, for example, the selected contact information acquisition means 312 can store in advance contact types indicating types according to the contact content that should be displayed on the sender's user terminal 100, store contact information including the pre-stored contact types separately from other contact information, and acquire contact information including the pre-stored contact types as selected contact information. The selected contact information acquisition means 312 preferably acquires the usage reservation information from the storage unit 305 based on a type of contact information included in the usage reservation information, which indicates that the contact content is a usage reservation. That is, for usage reservation information in which the contact content is a usage reservation for a specific facility, there is a high need for the user U to check the contact content related to the reservation after making the usage reservation.

[0071] The server-side transmission means 313 can be configured by, for example, the control unit 301 and communication unit 304 of the building management server 300. The server-side sending means 313 sends the selected contact information and notification information acquired by the selected contact information acquiring means 312 to the user terminal 100 that sent the selected contact information. The server-side transmission means 313 can be configured, for example, so that the control unit 301 and the communication unit 304 work together to transmit the selected contact information acquired by the selected contact information acquisition means 312 and the notification information stored in the memory unit 305 to the user terminal 100 that sent the selected contact information. The user terminal 100 that is the sender of the selected contact information to which the information is to be sent can be identified, for example, by the client ID included in the selected contact information or the IP address of the user terminal 100 that sent the selected contact information.

[0072] For example, it is preferable that the server-side transmitting means 313 transmits notification information received from the administrator terminal 200 used by the building manager M associated with the user U who sent the selected contact information to the user terminal 100 who sent the selected contact information. That is, when notification information received from the administrator terminal 200 used by the building manager M associated with the user U who sent the selected contact information is sent to the user terminal 100 who sent the selected contact information, notification information sent by a building manager M of another building is not sent to the user terminal 100. This provides excellent security and makes it easy for the user U to check notifications.

[0073] The user side display means 114 can be configured by, for example, the control unit 101 and the display unit 102 of the user terminal 100. The user-side display means 114 displays the contact content and notice content contained in the selected contact information and notice information received from the building management server 300 on the display unit 102 together with the respective associated contact related dates and notice related dates. The manner in which the contact and notice contents are displayed may be changed as appropriate, provided that the contact and notice contents are displayed together with the associated contact-related date and notice-related date, respectively. Furthermore, for example, the user-side display means 114 may display a calendar on the display unit 102, and, based on the contact-related dates and notice-related dates, display the contact content and notice content in association with the calendar dates on the display unit 102. As a form of such display, the contact content and notice content may be displayed directly in the boxes representing each date on the calendar, or a display element such as a mark may be provided in the portion of a predetermined date on the calendar, and the contact content and notice content may be displayed by selecting the date to which the display element is assigned.

[0074] The safety confirmation means 115 can be configured by, for example, the control unit 101, the input unit 103, the communication unit 104, and the display unit 102 of the user terminal 100. The safety confirmation means 115 includes a means for accepting input of safety information indicating the safety of user U and transmitting the input safety information to the building management server 300, and a means for receiving specific information identifying other user U and safety information of the other user U from the building management server 300, and displaying the name, etc. identifying the other user U and the safety of the other user U. The safety confirmation means 115 may be configured, for example, so that the user terminal 100 displays a page for inputting safety information on the display unit 102 and accepts input of safety information from the user U. When accepting input of safety information, for example, in addition to the safety of the user U, input of the user U's location, a message from the user U to another user U, etc. may also be accepted. The safety confirmation means 115 may be configured, for example, so that the user terminal 100 receives specific information identifying other users U and safety information of other users U from the building management server 300, and displays information such as the names of other users U and the safety of other users U on the display unit 102. When displaying the safety, in addition to the safety of each user U, the location of user U, messages from user U to other users U, etc. may also be displayed.

[0075] The safety information receiving means 314 can be configured by, for example, the control unit 301 and the communication unit 304 of the building management server 300. The safety information receiving means 314 receives safety information indicating the safety of one user U from one user terminal 100 used by the user U. The safety information receiving means 314 may be configured, for example, so that the control unit 301 and the communication unit 304 work together to receive safety information from the user terminal 100. It is also preferable that the safety information receiving means 314 receives the safety information and stores the safety of the specified user U in the storage unit 305 together with specific information that identifies the specified user U. As such specific information, the client ID of the user U may be used as shown in FIG.

[0076] The safety information transmission means 315 can be configured by, for example, the control unit 301 and the communication unit 304 of the building management server 300. The safety information transmission means 315 transmits user U identification information that identifies the user U and the safety information of the user U to other user terminals 100 used by other users U in the same building as the user U related to the received safety information. The safety information transmitting means 315 can be configured, for example, so that the control unit 301 and the communication unit 304 work together to transmit specific information and safety information about user U in a specified building to the user U in the specified building based on the safety information received by the safety information receiving means 314.

[0077] (Processing flow in the embodiment) An example of the processing flow of the building management system according to this embodiment will be described below with reference to the sequence diagram of the building management system shown in Fig. 7 and the screen diagrams shown in Fig. 8 to Fig. 17. Note that the screen diagrams shown in Fig. 8 to Fig. 17 all represent screens displayed on the display unit 102 of the user terminal 100, as an example.

[0078] 8(A) is a screen diagram of a login screen on the user terminal 100, FIG. 8(B) is a screen diagram of a home screen on the user terminal 100, and FIG. 8(C) is a screen diagram of a My Page on the user terminal 100. FIG.

[0079] As shown in FIG. 8(A), the user terminal 100 according to this embodiment can be used by the user U by inputting an ID and password and pressing a login button. After completing the login, the user terminal 100 transitions to the home screen shown in FIG. 8(B).

[0080] As shown in FIG. 8(B), the home screen displays start buttons for various functions such as "Phone," "Chat," "Reservations / Applications," "Library," "Posts," and "Disaster Prevention." Furthermore, the home screen displays announcements for the apartment building and local area. By displaying announcement information or contact information on the home screen, user U can check the announcements or contacts. The human-shaped icon displayed in the upper right corner of the home screen is a button for transitioning to My Page. By selecting the button for transitioning to My Page, the user terminal 100 transitions to the My Page screen.

[0081] As shown in Figure 8(C), the My Page screen displays the payment amount for the condominium, application and notification history, and reservation information for facilities and other equipment. For example, when a user U reserves a conference room or bicycle parking space in the condominium, the equipment reservation information is displayed so that the user can confirm the reservation for that equipment.

[0082] First, in contact information receiving step S11 in the user terminal 100, the contact information receiving means 111 configured in the user terminal 100 receives input of contact information as a message from the user U to the building manager M. The user terminal 100 in this embodiment is equipped with a plurality of processing methods for accepting input of contact information by the user U. The contact information accepted here preferably includes contact content, contact type, and contact-related date. However, it is sufficient that the contact information accepting means 111 is configured to be able to accept input of contact information including contact content, contact type, and contact-related date, and it may also be configured to accept input of contact information that does not include all of contact content, contact type, and contact-related date.

[0083] As an example of the processing in contact information receiving step S11, the screen when user U inputs contact information will be described with reference to Fig. 9. Fig. 9 is a diagram of screens that accept input of contact information on user terminal 100, arranged in order from (A) to (E).

[0084] For example, in response to user U selecting the post button in Fig. 8(B), user terminal 100 activates contact information receiving means 111. Then, user terminal 100 displays a reception screen for receiving input of contact information, as shown in Fig. 9(A).

[0085] As shown in Fig. 9(A), the user terminal 100 displays the options "Share your realization" and "Report" by the chatbot, thereby accepting a selection according to the contact made by the user U. Here, for example, by accepting a selection of "Share your realization" from the user U, the user terminal 100 displays options of "Suggestion / Idea," "Things to bring up," "Problems," "Trouble," and "Other" as types of realizations, as shown in Fig. 9(B), and accepts a selection of a contact type according to the contact made by the user U.

[0086] Next, as shown in Fig. 9(C), the user terminal 100 prompts the user U to input a message indicating the content of the message, and accepts the input of the message from the user U. In this case, the user U inputs the sentence "The plants at the front entrance have been vandalized," and the user terminal 100 treats this as the content of the message.

[0087] Next, as shown in Fig. 9(D), the user terminal 100 receives an input from the user U as to whether or not the received contact content is to be made public to other users U, etc. Upon receiving the input as to whether or not the contact content is to be made public to other users U, etc., the user terminal 100 completes the reception of the input of the contact content and contact type from the user U, as shown in Fig. 9(E).

[0088] As explained above, the user terminal 100 stores multiple contact types in advance, and determines the contact type according to the contact content by accepting a selection from an option according to the contact content from the user U. Then, by accepting written input of the contact content by the user U, the user terminal 100 acquires contact information including the contact content and the contact type. 9, the contact information receiving step S11 does not accept input of a contact-related date. However, the user terminal 100 is not required to accept input of information including the contact content, contact type, and contact-related date for all information representing a contact from the user U to the building manager M.

[0089] Although not shown, when user U selects "Report" in Figure 9(A), the user terminal 100 displays "Request for battery replacement," "Request for cleaning of dirt," "Discovery of unauthorized parking," and "Request for repair" as possible types of contact, and allows user U to select an appropriate type of contact from these.

[0090] As an example of the process in contact information receiving step S11, the screens when user U inputs usage reservation information, which is a type of contact information, will be described using Figures 10 and 11. Figures 10 and 11 are screen diagrams of screens that accept input of usage reservation information on user terminal 100, arranged in order from Figure 10(A) to Figure 10(D), and then from Figure 11(E) to Figure 11(G).

[0091] For example, in response to user U selecting the reservation / application button in Fig. 8(B), the user terminal 100 activates the contact information receiving means 111. Then, the user terminal 100 displays a reception screen for receiving input of contact information, as shown in Fig. 10(A). Note that, here, as a type of contact information, input of use reservation information representing a reservation for use of facilities or equipment such as equipment of the building, or application information representing an application, notification, or other request for the building to the building manager M is accepted.

[0092] As shown in FIG. 10(A), the user terminal 100 accepts a selection in response to a message from user U by displaying the options "facility reservation" and "application / notification" using a chatbot. Here, for example, by accepting a selection of "facility reservation" by user U, the user terminal 100 displays candidate facilities for user U's reservation as shown in FIG. 10(B), and accepts the selection of a facility in response to user U's reservation. Here, "small conference room" is selected as the reservation target in the reservation information, and the user terminal 100 handles the reservation of the small conference room as the content of the message. In this embodiment, a "small conference room" and a "bicycle parking area for visitors" are displayed as candidates, but various facilities that can be reserved for use, such as parking lots for visitors, guest rooms, karaoke sets, carts, or warehouses, or other facilities or equipment in a building, can also be displayed as candidates.

[0093] Next, as shown in FIG. 10(C), the user terminal 100 displays reservation date candidates for the selected facility on the display unit 102 and accepts input of the reservation date from the user U. Here, an example is shown in which "today" is selected as the date for using the small conference room. The user terminal 100 then treats "today (February 28, 20xx)," the date for using the small conference room, as a contact-related date.

[0094] 10(D), the user terminal 100 displays on the display unit 102 candidate start times for the selected facility on the reservation date for which the facility can be reserved, and accepts input of the start time for use from the user U. Here, as an example, the start time for use is accepted as "18:00" from the user U. 11(E), the user terminal 100 displays on the display unit 102 candidate end times for the selected facility on the reservation date, and accepts input of the end time from the user U. Here, as an example, the user U inputs "20:59" as the end time. Here, the user terminal 100 accepts input of the start time and end time of use on the reservation date of the equipment from the user U by displaying candidates for the start time and end time of use on the display unit 102. However, the contact-related date in the usage reservation information may be date and time information including the start time and end time of use, or may be only date information without time information.

[0095] Next, as shown in Fig. 11(F), the user terminal 100 displays on the display unit 102 confirmation information of the usage reservation, including the name of the facility and the date and time of use of the facility, input from the user U. The user terminal 100 accepts input confirming the usage reservation from the user U, and notifies the user U of the completion of the usage reservation, as shown in Fig. 11(G).

[0096] As explained above, the user terminal 100 stores multiple contact types in advance, and determines the contact type as a type indicating that the contact content is a reservation for use based on the selection of an option by the user U. The user terminal 100 then receives the selection of the facility that the user U will use, thereby acquiring the contact content that includes the reservation for use of the specified facility. The user terminal 100 also receives the input of the date that the facility will be used by the user U, thereby acquiring a contact-related date that indicates the date that the facility will be used.

[0097] As an example of the processing in contact information reception step S11, the screens when user U inputs information related to an application or notification, which is a type of contact information, will be described using Figures 12 and 13. Figures 12 and 13 are screen diagrams of screens that accept input of information related to an application or notification on user terminal 100, arranged in order from Figure 12(A) to Figure 12(D), and then from Figure 13(E) to Figure 13(F).

[0098] For example, in response to user U selecting the reservation / application button in Fig. 8(B), the user terminal 100 activates the contact information receiving means 111. Then, the user terminal 100 displays a reception screen for receiving input of contact information, as shown in Fig. 12(A).

[0099] As shown in FIG. 12(A), the user terminal 100 accepts a selection in response to a contact from the user U by displaying the options of "facility reservation" and "application / notification" using a chatbot. Here, for example, by accepting the selection of "application / notification" by the user U, the user terminal 100 displays the options of "apartment management association membership notification and occupancy notification," "pet keeping notification," "parking lot use application," and "parking lot use cancellation notification" as types of application or notification, as shown in FIG. 12(B). Here, as an example, a case where the user U selects "pet keeping notification" will be described. Here, the user terminal 100 may treat the type of application or notification, such as a "Condominium Management Association Membership Notification and Occupancy Notification" selected by the user U as the contact type, or may treat the broader "application for application, notification, etc." as the contact type. In other words, the classification of contact types can be adjusted in breadth and narrowness as appropriate, and can be determined as appropriate from the perspective of what type of contact information to acquire by the selected contact information acquisition means 312 in relation to the contact information to be acquired by the selected contact information acquisition means 312 and displayed on the user terminal 100.

[0100] Next, as shown in Fig. 12(C), the user terminal 100 prompts the user U to take a photograph of the document showing the contact content. Here, the user terminal 100 activates a photographing means connected to the user terminal 100, thereby enabling the user U to take a photograph of the document showing the contact content.

[0101] 12(D), the user terminal 100 displays the "Pet Keeping Notification" placed on a table or the like, as seen through the lens of the imaging means, in the display window 151. At this time, the user U can select the shutter button to capture an image including the "Pet Keeping Notification" form.

[0102] Next, as shown in Fig. 13(E), the user terminal 100 displays an image including a predetermined application form photographed by the photographing means, and prompts the user U to check the photographed image. Then, when the user U selects the submit button, the image including the predetermined application form is obtained as shown in Fig. 13(F).

[0103] As explained above, user terminal 100 stores multiple contact types in advance, and determines the contact type as a type indicating that the contact content is the submission of a form related to a specified application based on the selection of an option by user U. Then, by accepting submission of an image by user U that includes the specified form, user terminal 100 acquires the contact content, including the submission of the specified form included in the image. 12 and 13, the contact information receiving step S11 does not accept input of a contact-related date. However, the user terminal 100 is not required to accept input of information including the contact content, contact type, and contact-related date for all information representing a contact from the user U to the building manager M.

[0104] Next, in a user-side transmission step S12 in the user terminal 100, the user-side transmission means 112 configured in the user terminal 100 transmits the contact information to the building management server 300. The user terminal 100 in this embodiment reads out the contact information input received in the contact information receiving step S11, and transmits the contact information to the building management server 300 via a communication line.

[0105] More specifically, as an example, when the input of contact information is completed by the operation of the user U, the user terminal 100 transmits the input contact information to the building management server 300. As a result, a message from the user U to the building manager M is immediately transmitted to the building management server 300, and the message can be shared with the building manager M by the building management server 300. However, the manner in which the contact information is sent may be any manner in which the contact information is sent to the building management server 300; for example, the user terminal 100 may read the contact information from the memory unit 105 at a predetermined interval, and send all of the contact information entered by user U over a predetermined period of time to the building management server 300.

[0106] In addition, in the notice information receiving step S21 in the manager terminal 200, notice information receiving means 211 configured in the manager terminal 200 receives input of notice information as a notice from the building manager M to the user U. As an example, the administrator terminal 200 may be equipped with a plurality of processing methods for accepting input of notification information by the building administrator M, similar to the user terminal 100. Note that the notification information accepted here preferably includes the notification content and the notification-related date. However, it is sufficient that the notification information accepting means 211 is configured to be able to accept input of notification information including the notification content and the notification-related date, and it may also be configured to accept input of notification information that does not include all of the notification content and the notification-related date.

[0107] Furthermore, the notice information in this embodiment includes an attribute of the notice type as shown in Fig. 5. Therefore, in the notice information receiving step S21, the notice type may be acquired together with the notice content. As a method for acquiring the notification type, various methods can be adopted, such as the manager terminal 200 pre-holding multiple notification types and accepting a selection from the building manager M based on the notification content, thereby determining the contact type based on the notification content.

[0108] Next, in a manager-side transmission step S22 in the manager terminal 200, the manager-side transmission means 212 configured in the manager terminal 200 transmits the notification information to the building management server 300. The manager terminal 200 in this embodiment reads out the notification information received in the notification information receiving step S21, and transmits the notification information to the building management server 300 via a communication line.

[0109] More specifically, as an example, when the input of notification information is completed by the operation of the building manager M, the manager terminal 200 transmits the input notification information to the building management server 300. As a result, the notification from the building manager M to the user U is immediately transmitted to the building management server 300, and the notification can be shared with the user U by the building management server 300. However, the manner of sending the notification information may be any manner in which the notification information is sent to the building management server 300, and for example, the manager terminal 200 may read the notification information from the memory unit 205 at a predetermined interval, and send all the notification information entered by the building manager M over a predetermined period of time to the building management server 300.

[0110] Next, in a server-side receiving step S31 in the building management server 300, the server-side storage means 311 configured in the building management server 300 receives the contact information from the user terminal 100 and the notification information from the manager terminal 200. Then, in a server-side storage step S32 in the building management server 300, the server-side storage means 311 configured in the building management server 300 stores the received contact information and notification information in the storage unit 305.

[0111] The building management server 300 in this embodiment receives contact information or notice information, and stores the received contact information and notice information in the auxiliary storage unit 305b. More specifically, the contact information or notice information is organized by attribute information included in the record, and the information is added to the contact information table or notice information table shown in FIG. 5 and stored.

[0112] Next, in the selected contact information acquisition step S33 in the building management server 300, the selected contact information acquisition means 312 configured in the building management server 300 acquires, based on the contact type, information from the storage unit 305 that should be displayed on the sender's user terminal 100. Note that, of the acquired contact information, the information that should be displayed on the sender's user terminal 100 is treated as selected contact information. As a more specific example, from the contact information stored in the auxiliary memory unit 305b of the building management server 300, contact information sent by a specific user U is extracted based on the client ID contained in the contact information, and further, the information from the contact information that should be displayed on the user terminal 100 that sent the contact information is extracted based on the contact type contained in the contact information, thereby obtaining selected contact information to be displayed on the user terminal 100 that sent the contact information.

[0113] Next, in a server-side sending step S34 in the building management server 300, the server-side sending means 313 configured in the building management server 300 sends the selected contact information and notice information acquired in the selected contact information acquisition step S33. In this embodiment, the building management server 300 reads out notification information from the auxiliary memory unit 305b in addition to the selected contact information acquired in the selected contact information acquisition step S33, and transmits the selected contact information and the notification information to the user terminal 100 that sent the selected contact information via a communication line.

[0114] Preferably, the building management server 300 transmits to the user terminal 100 that sent the selected contact information the selected contact information acquired by the selected contact information acquisition means 312 and notification information received from the administrator terminal 200 used by the building manager M associated with the sender user U. In this case, even if multiple different building management systems manage multiple buildings, the building management server 300 can use stored information that associates the user U of a specific building with the manager of that specific building to send notification information sent by the manager associated with that user U to the specific user U. This enables the building management system to manage multiple buildings in a unified manner and to provide appropriate information to the user U.

[0115] Next, in user-side receiving step S13 in user terminal 100, user terminal 100 receives the selected contact information and notice information sent in server-side sending step S34.

[0116] Next, in a user-side display step S14 in the user terminal 100, the contact content and notification content contained in the selected contact information and notification information received in the user-side receiving step S13 are displayed on the display unit 102 together with the associated contact related dates and notification related dates, respectively.

[0117] The display mode of the contact content and the notice content may be various, as long as the contact content and the notice content are displayed together with the contact-related date or the notice-related date. For example, the contact content and the notice content may be displayed in a list together with the contact-related date or the notice-related date, respectively, or the contact content and the notice content may be displayed in the date portion of a calendar displayed on the display unit 102 of the user terminal 100, corresponding to the contact-related date or the notice-related date, respectively. 8(B), the user terminal 100 can display at least one of the contact content or the notice content together with the contact-related date or the notice-related date on the display unit 102. In FIG. 8(B), the notice content "Looking for participants for morning monitoring" is displayed together with the notice-related date, which is the day on which the morning monitoring will be conducted. Similarly, in FIG. 8(C), the contact content indicating a reservation for use of a small conference room called "small conference room" is displayed together with the contact-related date, which is the date and time on which the small conference room can be used.

[0118] As an example, as shown in Figures 14 and 15, the user terminal 100 may display a calendar on the display unit 102, and display the contact content and notification content on the display unit 102 in correspondence with the dates on the calendar based on the contact-related dates and notification-related dates of the contact information and notification information. In FIG. 14(A), January 2, 20xx is selected on the calendar by the user U's operation on the user terminal 100. In this case, the user terminal 100 displays contact content and notification content with January 2, 20xx as the contact-related date or the notice-related date in the content display area 152 for displaying contact content or notification content, which is provided on the display unit 102. Here, two notification content items with January 2, 20xx as the notice-related date are displayed in the content display area 152. Similarly, in FIG. 15, January 28, 20xx is selected on the calendar by the user U's operation on the user terminal 100. In this case, the user terminal 100 displays contact content and notification content with January 28, 20xx as the contact-related date or the notice-related date in the content display area 152, which is provided on the display unit 102. Here, one contact content item with January 28, 20xx as the contact-related date is displayed in the content display area 152.

[0119] Furthermore, the user terminal 100 receives a selection of a contact type or a notice type included in at least one of the contact information or the notice information, and displays the contact content or the notice content according to the selected type on the display unit 102. In this embodiment, when user U selects the downward arrow shown in FIG. 14(A), the user terminal 100 displays a selection item for the contact type or notice type as shown in FIG. 14(B). In FIG. 14(B), the selection item for the contact type or notice type is displayed using a pull-down list. Then, when user U selects a specific type in FIG. 14(B), the user terminal 100 displays the contact content and notice content corresponding to the selected type on the display unit 102. For example, if user U selects "ABC Apartment Notice" in FIG. 14(B), the user terminal 100 displays the notice content for the apartment notice on the display unit 102 as shown in FIG. 14(C). Also, if user U selects "Patent City Nishi Ward Notice" in FIG. 14(B), the user terminal 100 displays the notice content for the local notice on the display unit 102 as shown in FIG. 14(D). The display of the contact content and notice content corresponding to the selected type is processed according to the contact type or notice type. Furthermore, as for the contact type and the notice type, for example, a type common to both the contact type and the notice type may be set. As an example, when the user U selects the type "water", contact information whose contact type is water and whose notice content is a water failure and notice information whose notice type is water and whose notice content is a notice of a water inspection may be displayed.

[0120] The following describes safety confirmation functions and accounting functions that are preferably included in the building management system.

[0121] (Safety confirmation function) The building management server 300 stores a user U of a specific building in association with other users U of the same specific building. That is, as shown in the user U table in Fig. 4, users U of the same building are associated with each other by a common building ID. Furthermore, as shown in FIG. 6, the building management server 300 includes a safety information receiving means 314 that receives safety information indicating the safety of a predetermined user U from the user terminal 100 used by the user U. Furthermore, as shown in FIG. 6, the building management server 300 includes a safety information transmission means 315 that transmits user U identification information that identifies a specific user U and safety information of the specific user U to the user terminal 100 used by the other user U mentioned above.

[0122] The safety information receiving means 314 is configured by, for example, the control unit 301 and the communication unit 304 . The safety information receiving means 314 receives safety information indicating the safety of a predetermined user U from the user terminal 100 used by the user U. The safety information receiving means 314 receives, for example, safety information input by a specific user U operating the user terminal 100 from the user terminal 100. The safety information receiving means 314 may store the safety information in the auxiliary storage unit 305b of the building management server 300, for example, as shown in the table representing the safety information in FIG. 5. The safety information receiving means 314 may also receive the safety information of the building manager M in addition to the user U from the manager terminal 200.

[0123] As shown in FIG. 5, for example, the safety information may include a client ID, a reception date and time, safety, location, and message attributes. The client ID is the same as the client ID in the user U table shown in Figure 4, and is used as user U identification information to identify the user U who sent the safety information. The reception date and time is the date and time the building management server 300 received the safety information, and indicates the situation at what point in time the information on safety and location contained in the safety information is. Safety indicates the safety of user U by information such as whether they are safe or need help. Location indicates the location of user U by information such as home, out, workplace, or school. The message is entered by user U by operating a keyboard, etc., and indicates the text that user U wants to convey to other users U in the building.

[0124] The safety information transmitting means 315 is configured by, for example, the control unit 301 and the communication unit 304 . The safety information transmission means 315 transmits user U identification information that identifies a specific user U and the safety information of the specific user U to the user terminal 100 used by the other user U. The safety information transmission means 315 may be configured to transmit safety information to the user terminal 100, for example, in response to receiving a request for transmitting safety information from the user terminal 100. The safety information transmission means 315 transmits at least user U identification information that identifies a specific user U and safety information for the specific user U. In this embodiment, a client ID is used as the user U identification information, but the user U identification information is not limited to this. For example, the user U's name or the like may be used as the user U identification information. Furthermore, in this embodiment, safety information selectively input by the user U is used as the safety information. However, the safety information is not limited to information input by the user U by selecting an option such as "safe" or "help needed." For example, text or the like input by the user U may be used as the safety information.

[0125] Next, the function of the user terminal 100 in safety confirmation will be described with reference to Fig. 16. Fig. 16 is an image diagram of the user terminal 100 according to the embodiment, showing screen images related to safety confirmation arranged in order from (A) to (B) and from (A) to (C).

[0126] The user U can activate the safety confirmation function by selecting "Disaster Prevention" in the bottom right of the home screen in Fig. 8(B). When the user U selects "Disaster Prevention", the user terminal 100 displays the first screen of the safety confirmation function shown in Fig. 16(A). When the user terminal 100 receives the selection of "Send safety information" in Fig. 16(A), it displays the safety information transmission screen shown in Fig. 16(B) on the display unit 102. When the user terminal 100 receives the selection of "Check safety information" in Fig. 16(A), it displays the safety information confirmation screen shown in Fig. 16(C) on the display unit 102.

[0127] As shown in Fig. 16(B), the safety transmission screen allows the user U using the user terminal 100 to input safety information. When transmitting safety information, the user selects "safe" or "needs help" and "at home" or "away" from the safety options and location options displayed on the display unit 102 of the user terminal 100. Furthermore, the user U can input a message by operating the user terminal 100 if desired.

[0128] The user terminal 100 accepts input of safety information by the user U and transmits it to the building management server 300. When transmitting, for example, in addition to the safety information, a client ID may be transmitted to the building management server 300 as user U identification information. Note that with regard to the user U identification information, the user terminal 100 may not transmit the client ID, etc., and the building management server 300 that receives the safety information may recognize the user U identification information based on the IP address, account information, etc. of the user terminal 100.

[0129] As shown in Fig. 16(C), the safety confirmation screen allows the user to confirm the safety of user U in the shared building. In Fig. 16(C), as an example of safety confirmation, the display unit 102 of the user terminal 100 displays the name of user U, the location of user U, the update date and time which is the date and time when the safety information was entered or received by the building management server 300, and a message from user U. The user terminal 100 receives information such as the client ID, reception date and time, safety status, location, and message from the building management server 300, as in the safety information shown in Fig. 5, and displays the safety status of each user U on the display unit 102 based on the received information. Regarding the name of user U, the user terminal 100 may receive the client ID, compare the client ID with the name of user U, and display the name of user U on the display unit 102. Alternatively, the building management server 300 may compare the client ID with the name of user U, and the user terminal 100 may receive and display the name of user U. The display unit 102 may also display the room number of user U instead of the name of user U, based on the user U identification information.

[0130] (Accounting function) Next, the accounting function will be described with reference to Fig. 17. Fig. 17 is a diagram showing an image of the user terminal 100 according to the embodiment, and is a diagram showing an image of a screen for confirming the billed amount for the building.

[0131] As shown in FIG. 17, the user terminal 100 displays on the display unit 102 the bill for the building to be paid by the user U who uses the user terminal 100. For example, the building management server 300 may store the billing amount for each user U in the auxiliary storage unit 305b. Specifically, as an example, the building management server 300 stores in the auxiliary storage unit 305b base amounts, such as management fees and repair reserve funds, to be billed equally to each user U for each specific building. Furthermore, the building management server 300 references the facility usage reservation information received from the user terminal 100 and checks the facility usage status during the billing calculation period. Furthermore, the building management server 300 calculates the facility usage fee based on the facility usage status. The building management server 300 or the user terminal 100 then adds the facility usage fee to the base amount. The building management server 300 or the user terminal 100 then adds a predetermined amount, such as an internet usage fee, to the added base amount and facility usage fee, as necessary, to calculate the billing amount for the specified calculation period, and displays the billing amount on the display unit 102 of the user terminal 100. This allows the building management system to make it easier for the user U to check the amount billed to the user U, including the base amount and the facility usage fee.

[0132] (Actions and effects of the building management system according to the embodiment) In the building management system according to this embodiment, the user terminal 100 includes a contact information receiving means 111 that receives input of contact information from a user U to a building manager M, the contact information including contact content indicating the content of the contact, a contact type indicating a type according to the contact content, and a contact-related date indicating a date related to the contact content, and a user-side sending means 112 that sends the contact information to the building management server 300. Furthermore, the manager terminal 200 includes a notification information receiving means 211 that receives input of notification information from the building manager M to a user U, the notification information including notification content indicating the content of the notification and a notification-related date indicating a date related to the notification content, and a manager-side sending means 212 that sends the notification information to the building management server 300. Furthermore, the building management server 300 included a server-side storage means 311 that stores in the storage unit 305 the contact information received from the user terminal 100 and the notification information received from the administrator terminal 200, a selected contact information acquisition means 312 that acquires from the storage unit 305 selected contact information that is information to be displayed on the user terminal 100 that sent the contact information based on the contact type, and a server-side transmission means 313 that transmits the selected contact information and notification information acquired by the selected contact information acquisition means 312 to the user terminal 100 that sent the selected contact information. Furthermore, the user terminal 100 included a user-side display means 114 that displays on the display unit 102 the contact content and notification content included in the selected contact information and notification information received from the building management server 300, together with the associated contact-related date and notification-related date, respectively. Therefore, the building management server 300 acquires, from among the multiple pieces of contact information, information to be displayed on the user terminal 100 based on the contact type as selected contact information. Furthermore, the user terminal 100 receives the selected contact information and the notice information, and displays the contact content and notice content together with the contact-related date and notice-related date on the display unit 102. This makes it easy for user U to check contact from user U to building manager M and notices from building manager M to user U. More specifically, among the contact information from user U to building manager M, it is possible to display selected contact information that requires confirmation even after the contact information is sent by displaying it on user terminal 100, and by being able to display notices from building manager M, user U can check the information about the building that user U needs to check, along with the dates related to that information.

[0133] In addition, in the building management system of this embodiment, the user-side display means 114 displays a calendar on the display unit 102, and based on the contact-related date and the notification-related date, displays the contact content and notification content on the display unit 102 in correspondence with the calendar dates. This allows users to easily grasp dates related to contacts or notices, such as application deadlines, facility use dates, and event dates, in calendar format.

[0134] In addition, in the building management system of this embodiment, the notification information further includes a notification type that indicates a type according to the notification content, and the user-side display means 114 receives a selection of a contact type or notification type included in at least one of the contact information or notification information, and displays the contact content and notification content according to the selected type on the display unit 102. Therefore, by selecting the type that the user U wishes to check, the user terminal 100 can display the contact information and notice information corresponding to the selected type on the display unit 102. This allows the user U to easily check the information that he or she wishes to check, even if there is a large amount of contact information and notice information.

[0135] In addition, in the building management system of this embodiment, the contact information includes usage reservation information in which the contact content is a reservation for use of a specified facility from a user U to a building manager M, the contact type is a type indicating that the contact content is a usage reservation, and the date on which the specified facility will be used is the contact-related date, and the selected contact information acquisition means 312 acquires at least the usage reservation information from the memory unit 305 as the selected contact information. For this reason, the selected contact information acquisition means 312 acquires usage reservation information, which is a type of contact information, as selected contact information from the storage unit 305. As a result, the usage reservation information is transmitted to the user terminal 100 by the server-side transmission means 313, and is displayed on the display unit 102 of the user terminal 100. Since usage reservation information regarding the reservation of facility usage is information that is checked later, particularly by the user U, the above configuration allows the user U to reliably check the reservation details of the facility even after the facility usage reservation has been made.

[0136] In addition, in the building management system of this embodiment, the building management server 300 stores a correspondence between a user U of a specified building and a building manager M of the specified building, and the server-side transmission means 313 transmits to the user terminal 100 that sent the selected contact information the selected contact information acquired by the selected contact information acquisition means 312 and notification information received from the manager terminal 200 used by the building manager M that is associated with the sending user U. Therefore, the building management server 300 will transmit to the user U who sent the selected contact information, notification information sent by the building manager M of the same building as the user U, out of the notification information sent by the building managers M of multiple buildings stored in the memory unit 305. As a result, even when the building management system manages information about multiple buildings, it will not send notifications from building managers M of different buildings to the user U, and can transmit information about the appropriate building to each user terminal 100.

[0137] In addition, the building management system of this embodiment includes a building management server 300 that stores a first user U of a specified building and a second user U of a specified building in association with each other, a safety information receiving means 314 that receives safety information indicating the safety of the first user U from the first user terminal 100 used by the first user U, and a safety information sending means 315 that sends user U identification information that identifies the first user U and the safety information of the first user U to the second user terminal 100 used by the second user U.
