It is operation | movement explanatory drawing which shows the other operation example same as the above. It is a block diagram of the server used for Embodiment 2. FIG. 6 is a block diagram illustrating a third embodiment.

  In the embodiment described below, an example in which a plurality of network servers (hereinafter abbreviated as “servers”) are each provided with a service providing unit that provides a service will be described. The service provided by the service providing unit to the user is exemplified by a service related to the amount of resources used as a management target for one building such as an office building, a store building, or a commercial building. Here, the resource means a resource consumed by the device such as electric power, gas, water, and heat.

  The above-described configuration example in the embodiment described below is not intended to limit the technical content, but the technology described in this embodiment is a configuration in which a plurality of service providing units are provided in one server. Applicable. Therefore, the minimum configuration may include only one server. The server may be configured to function as a single server by linking a plurality of computers in addition to the configuration configured by a single computer.

  In addition, when the service target is a building, the management target may include a plurality of buildings, or may be one level or one room of one building. Furthermore, the management target may be other than a building, and may be, for example, a park or a street. That is, the management target is appropriately set by the user.

  The management target includes a plurality of monitoring points, and monitors information for each monitoring point. Hereinafter, this information is referred to as monitoring information. The monitoring information includes information related to the amount of resources used, information related to at least one of disaster prevention and crime prevention, information related to device operation, and the like. When the resource is power, the monitoring information related to the resource amount is selected from the amount of power passing through the main breaker, the amount of power passing through the branch breaker, the amount of power passing through the outlet, the amount of power consumed by the device, and the like. In addition, the monitoring point is set so that these amounts of power can be monitored. The monitoring point is set in the same manner when the resource is water, gas, heat, or the like.

  Services include services related to the amount of resources, services related to disaster prevention and crime prevention, services that monitor and maintain equipment failures and lifetimes, and services that manage carbon dioxide emissions. May be. The service is assumed to be a service that performs at least one of monitoring and control on a management target. The monitoring information and the monitoring points are appropriately determined according to the types of these services.

(Embodiment 1)
As shown in FIG. 1, the service providing system of this embodiment includes a plurality of servers 101, 102,. Hereinafter, when it is not necessary to distinguish the servers 101, 102,.

  Each server 10 is connected to a wide area network NT1 such as the Internet, and communicates with a user terminal 20 connected to the wide area network NT1. Further, the server 10 communicates with the measuring device 30 arranged at the monitoring point in order to acquire the resource amount used at the monitoring point set as the management target as monitoring information. The server 10 includes a communication interface unit (hereinafter referred to as “communication I / F unit”) 111 for communicating with the user terminal 20 and a communication I / F unit 112 for acquiring monitoring information from the measurement device 30. With. When the server 10 provides a service to be controlled, a control target is arranged at a monitoring point, and the communication I / F unit 112 transmits control information for instructing control content to the control target.

  The user terminal 20 includes an input device selected from a keyboard, a mouse, a touch panel, and the like, and an output device such as a display device, and may have any configuration as long as the web browser operates. .

  The server 10 includes a service providing unit 12 that provides the above-described service to the user terminal 20 and a database system that stores data used by the service providing unit 12 to provide the service. The database system stores user information regarding users, management information regarding management targets, and unique information specific to services provided by the service providing unit 12.

  The user information is information for identifying the user, and includes the user name, identification information assigned to the user, and the contact information (telephone number, mail address, etc.) of the user. In addition, when the management target is a building, the management information includes a building name, identification information assigned to the building, and a building address. The management information may include information regarding the monitoring point. Since the management target is managed by the user, the management information is related to the user information.

  The above-described user information and management information include many common contents regardless of the type of service. Therefore, information that has the same content regardless of the type of service among user information and management information is treated as common information that is distinguished from unique information. That is, many items included in the user information and the management information become common information common to all the servers 101, 102,. On the other hand, the unique information specific to the service includes monitoring information acquired from the monitoring point or control information transmitted to the monitoring point.

  The database system distinguishes between a database system that stores user information and management information and a database system that stores unique information. That is, the server 10 includes two database systems: a common information management unit 13 in which common information is registered, and an individual information management unit 14 in which unique information is registered. Each of the common information management unit 13 and the individual information management unit 14 includes a storage unit having a large-capacity storage device such as a hard disk device, and an API (Application Programming Interface) for handling data stored in the storage unit. Prepare.

  The above example is simplified for ease of explanation, but in reality, the user information is a service number if the user is a business, and the service is a service related to carbon dioxide emissions. In some cases, it may include an exhaustor number. Such user information may differ depending on the type of user or service. The management information may include information indicating the country or region where the management target exists, information indicating the type of building, and the like. Such management information may differ depending on the type of service.

  Different user information and management information depending on the service are registered in the common information management unit 13, but are handled separately from the common information in the common information management unit 13. Processing of information registered in the common information management unit 13 but not handled as common information will be described later.

  The server 10 selects the reception processing unit 15 that presents an interactive web page on the user terminal 20 and the servers 101, 102,... That provide a desired service from the servers 101, 102,. And a selection processing unit 16 that enables the above. The cooperation range is preset in the selection processing unit 16.

  In this embodiment, since the service providing unit 12 has a one-to-one correspondence with the servers 101, 102,..., The selection processing unit 16 uses the addresses of the servers 101, 102,. The service providing unit 12 is selected. The selection processing unit 16 only needs to have a function of setting a cooperation range and a function of selecting from the cooperation range for the service providing unit 12 that provides a desired service. Therefore, if unique identification information is assigned to each service providing unit 12, the selection processing unit 16 can also identify the service providing unit 12 using the identification information.

  The service providing unit 12 is an API for the user terminal 20 to use the service. The service providing unit 12 operates common information and unique information registered in the common information management unit 13 and the individual information management unit 14 in accordance with an instruction from the user terminal 20 to provide a required service to the user terminal 20. To do.

  As described above, the reception processing unit 15 presents an interactive web page on the user terminal 20. Note that the processing for authenticating the user will be described as already completed. That is, the reception processing unit 15 causes the user information to be input to the web page in the process of authenticating the user, and when the user information is input, the input user information is input to the service providing unit of the cooperation range. 12 is collated with the common information management unit 13 corresponding to 12. In short, the input user information is collated for the common information management unit 13 of all the servers 10 including the service providing unit 12 in the cooperation range.

  If the input user information exists in any of the common information management units 13, the reception processing unit 15 authenticates the user and permits the use of the service. In addition, after accepting the use of the service, the reception processing unit 15 presents a screen for selecting a service that can be provided in the cooperation range set in the selection processing unit 16 on the display device of the user terminal 20. Therefore, when the user operates the user terminal 20 and selects a desired service, the use of the selected service providing unit 12 is permitted.

  The service providing unit 12 uses the management information associated with the authenticated user information and provides a service for the management target included in the management information. That is, when registered in the common information management unit 13 corresponding to one of the service providing units 12 in the cooperation range, the user can use the services of other service providing units 12 within the cooperation range. become. In other words, the server 10 provided with the service providing unit 12 in the cooperation range will share the common information registered in the common information managing unit 13 and seamlessly provide the service provided by the service providing unit 12. Is possible. In the common information management unit 13, the reception processing unit 15 has a function of causing the user terminal 20 to select necessary management information in preparation for a case where a plurality of management information corresponding to user information exists. ing.

  As described above, the service providing unit 12 is provided in each of the servers 101, 102,..., And the common information managing unit 13 and the individual information managing unit 14 in which information necessary for using the service providing unit 12 is stored. The service providing unit 12 is provided in one-to-one correspondence. That is, as shown in the figure, each of the servers 101, 102,... Includes communication I / F units 111, 112, a service providing unit 12, a common information management unit 13, an individual information management unit 14, and a reception processing unit 15. The selection processing unit 16 is provided. Generally, when such a configuration is adopted, the user needs to connect to different servers 101, 102,... And register user information for each service to be received. .

  In the present embodiment, as described above, if the service is within the cooperation range set in advance in the selection processing unit 16, the user who is authenticated by the reception processing unit 15 provides the service of the other server 10. The service provided by the unit 12 can also be used. In addition, since the service providing unit 12 also uses management information associated with user information, there is no need to register common information for each service, and the user only needs to register the common information once, and the plurality of services. The providing unit 12 can be used.

  Of the user information and management information registered in the common information management unit 13, information that differs depending on the service cannot be handled as common information in practice, and is treated in the same way as unique information. That is, the reception processing unit 15 excludes this type of information from the common information, and provides it to the service providing unit 12 together with the unique information as necessary.

  An example of operation with the above-described configuration is shown in FIGS. The illustrated example shows a case where a user whose common information is registered in the server 102 uses the service providing unit 12 of the server 101. That is, the common information regarding the user is not registered in the common information management unit 13 of the server 101 but is registered in the common information management unit 13 of the server 102.

  FIG. 2 shows an operation example when the user terminal 20 accesses the server 101. When the user terminal 20 accesses the reception processing unit 15 of the server 101 through the wide area network NT1 (P11), the reception processing unit 15 waits for input of user information. When user information is input to the user terminal 20, the reception processing unit 15 of the server 101 collates the user information for the common information management unit 13 in all the servers 101, 102,. (P12). In this example, since the input user information is registered in the common information management unit 13 of the server 102, the reception processing unit 15 receives the common information from the common information management unit 13 of the server 102 (P13), The user is authenticated using the user information of the common information.

  The reception processing unit 15 notifies the selection processing unit 16 of the authentication result (P14), and waits for the selection of the service providing unit 12 by the selection processing unit 16. The selection processing unit 16 selects the service providing unit 12 provided in the same server 101 by default. The selection processing unit 16 notifies the reception processing unit 15 of the selected service providing unit 12 (P15). The reception processing unit 15 notified of the service providing unit 12 selected from the selection processing unit 16 delivers the common information to the service providing unit 12 (P16). With such a series of processing, the user terminal 20 can use the service provided by the service providing unit 12 in the server 101.

  FIG. 3 shows an operation example when the user terminal 20 accesses the server 102. When the user terminal 20 accesses the reception processing unit 15 of the server 102 through the wide area network NT1 (P21), the reception processing unit 15 waits for input of user information. When user information is input to the user terminal 20, the reception processing unit 15 of the server 102 collates the user information for the common information management unit 13 in all the servers 101, 102,. (P22). In this example, since the input user information is registered in the common information management unit 13 of the server 102, the reception processing unit 15 receives the common information from the common information management unit 13 of the server 102 (P23), The user is authenticated using the user information of the common information.

  The reception processing unit 15 notifies the selection processing unit 16 of the authentication result (P24), and waits for the selection of the service providing unit 12 by the selection processing unit 16. In this example, the service providing unit 12 provided in the server 101 is selected, and the selection processing unit 16 notifies the reception processing unit 15 of the selected service providing unit 12 (P25). The reception processing unit 15 notified of the selected service providing unit 12 from the selection processing unit 16 delivers the common information to the service providing unit 12 through the wide area network NT1 (P26). Through the series of processes described above, the user terminal 20 can use the service provided by the service providing unit 12 in the server 101.

  Assume that the three servers 101, 102, and 103 are within the cooperation range, and each of the servers 101, 102, and 103 provides the following services one by one. That is, the server 101 is a service for visualizing the power consumption of the management target, the server 102 is a service for collecting the power consumption of the management target, and the server 103 is a service for monitoring the operation and failure of the equipment installed in the management target. provide. Further, it is assumed that the user uses a service that collects the amount of power used provided by the server 102 and registers user information only in the server 102.

  Under the above-described conditions, when the user intends to receive a service for visualizing the amount of power used provided by the server 101, the user accesses either the server 101 or the server 102. Regardless of whether the server 101 is accessed or the server 102 is accessed, the common information registered in the common information management unit 13 of the server 102 is used when the service provided by the server 101 is used.

  If the above-described configuration is adopted, the user can add the reception processing unit 15 and the selection processing unit 16 having the above-described functions to a plurality of servers 10 that provide different services. All services can be selected seamlessly. In other words, an environment in which a plurality of services are individually performed by a plurality of servers 10 is integrated, and it is as if a plurality of services can be selected by one server 10 for the user. In addition, it is possible to use the service with convenience.

  In the configuration example described above, the selection processing unit 16 enables selection of the service providing unit 12 provided in the other server 10, but a configuration in which the selection processing unit 16 is omitted is also possible. In this case, only the service providing unit 12 of the accessed server 10 can be used. Therefore, the user accesses a different server 10 for each service to be used, but since the common information is shared by the servers 10 in the cooperation range, the user information and management information are registered for each server 10. Therefore, convenience is improved as compared with the conventional configuration.

(Embodiment 2)
In the first embodiment, the configuration in which the common information registered in the common information management unit 13 is shared in the plurality of servers 10 that are the cooperation range has been described. When this configuration is adopted, when the user has already used the services of the plurality of servers 10, there is a possibility that the common information is duplicated in the plurality of servers 10. This embodiment demonstrates the function which produces | generates master identification information in order to manage the common information each registered into the some server 10 which is a cooperation range centrally.

  The master identification information is required to be unique in the cooperation range, but issuing master identification information after confirming uniqueness leads to an increase in processing load. Therefore, as shown in FIG. 4, the server 10 assigns an identifier to the information issuing unit 17 that issues the issuer identification information and the common information registered in the common information management unit 13, and issues the issuer identification to the identifier. And an identification information generation unit 18 for adding information. The identifier given to the common information only needs to be unique within the range of the common information management unit 13, and for example, a serial number is used.

  The issuer identification information is given to the service providing unit 12 so as to be identification information corresponding one-to-one. The publisher identification information is, for example, a 6-digit numerical value. A 2-digit country code assigned in accordance with International Telecommunication Union (ITU) regulations and a 4-digit serial number decided in each country Is used. Moreover, the identification information generation part 18 gives a 10-digit serial number to common information, for example. Since the issuer identification information and the identifier of the common information are determined in each server 10, the traffic of the wide area network NT1 does not increase and the processing load of the server 10 does not increase with communication. Is relatively small. In addition, unique information is generated in the cooperation range by combining the issuer identification information and the identifier of the common information.

  Using this, in this embodiment, the master identification information is represented by a 19-digit integer (int8), the lower 10 digits are the identifier of the common information, the next 6 digits are the issuer identification information, and the remaining upper 3 digits are Treat as spare. That is, the master identification information is substantially represented by a 16-digit integer. As described above, the identification information generation unit 18 generates the master identification information by adding the issuer identification information issued by the information issuing unit 17 to the identifier given to the common information.

  When the master identification information is associated with the common information as in the present embodiment, the user information input to the user terminal 20 is associated with the master identification information on a one-to-one basis. That is, when the user terminal 20 accesses the server 10 including the service providing unit 12 to be used, the user terminal 20 transmits master identification information to the server 10. The reception processing unit 15 of the server 10 can know in which server 10 the common information management unit 13 of the user information included in the master identification information exists by referring to the issuer identification information of the master identification information. it can.

  Therefore, the user information collation range is not the common information management unit 13 of all the servers 10 in the cooperation range, but the common information management unit 13 of one server 10 indicated by the issuer identification information. As a result, the processing load when collating user information is smaller than that of the configuration of the first embodiment, and the traffic in the wide area network NT1 when collating user information is reduced.

  In the configuration example described above, it is assumed that the server 10 includes the common information management unit 13 and the individual information management unit 14, but the common information management unit 13 and the individual information management unit 14 are network database systems. It is possible to build. In particular, when the service providing area covers a wide range, the common information management unit 13 and the individual information management unit 14 are preferably constructed as a distributed database.

  In addition, since an IP network such as the Internet is used as the telecommunication network that enables communication between the server 10 and the user terminal 20, the distributed database is also IP in order to hierarchize the addresses of the distributed database. It is preferable to be connected to a network. In this case, assuming that the IP network includes a domain name server (DNS), domain names are set in the common information management unit 13 and the individual information management unit 14 that construct the distributed database as follows.

  That is, the domain name is set so as to include at least a three-layer domain name including an upper domain name, a middle domain name, and a lower domain name. The upper domain name is set in common in the cooperation range, and is set to represent, for example, a provider that provides the service. The intermediate domain name is set so as to distinguish between the common information management unit 13 and the individual information management unit 14, for example, “.plat” for the common information management unit 13 and “.service” for the individual information management unit 14. And so on. Furthermore, the lower domain name uses issuer identification information when the middle domain name corresponds to the common information management unit 13 (in the case of “.plat”), and the middle domain name corresponds to the individual information management unit 14. In this case (in the case of “.service”), the service type is set to be distinguished. The reception processing unit 15 is connected to the common information management unit 13 and the individual information management unit 14 by using the middle domain name and the lower domain name. Other configurations and operations are the same as those of the first embodiment.

(Embodiment 3)
In the above-described embodiment, an example in which the reception processing unit 15 and the selection processing unit 16 are provided for each server (network server) 10 in which the service providing unit 12 is provided has been described. In the present embodiment, as shown in FIG. 5, a proxy server including a reception processing unit 45 and a selection processing unit 46, in addition to a server 10A including a service providing unit 12A, a common information management unit 13A, and an individual information management unit 14A. 40 is provided.

  The server 10 </ b> A includes communication I / F units 111 </ b> A and 112 </ b> A for communicating with the user terminal 20 and the measurement device 30. Accordingly, the server 10A has a configuration in which the reception processing unit 15 and the selection processing unit 16 are excluded from the server 10 described in the first embodiment. That is, the communication I / F units 111A and 112A, the service providing unit 12A, the common information managing unit 13A, and the individual information managing unit 14A are respectively the communication I / F units 111 and 112, the service providing unit 12, and the common information of the first embodiment. The same functions as those of the management unit 13 and the individual information management unit 14 are provided.

  On the other hand, the proxy server 40 includes a communication I / F unit 41 for communicating with the user terminal 20 and the server 10 </ b> A, and has the same function as the reception processing unit 15 and the selection processing unit 16. And a selection processing unit 46 having the above functions. That is, the reception processing unit 45 and the selection processing unit 46 are separated from the server 10A, and compared with the configuration in which the reception processing unit 45 and the selection processing unit 46 are provided in each server 10 as in the first embodiment. This simplifies the configuration of the server 10A.

  In this configuration, the user can use all the services in the cooperation range by accessing the proxy server 40. In this configuration, it is possible to use the service of each server 10A using the proxy server 40 as an entrance.

  Further, when using the service of each server 10A, the processing may be handed over to the proxy server 40. In this case, a user who has used the service of one of the servers 10A can use the service provided by the other server 10A by accessing the server 10A corresponding to the service.

  Other configurations and operations are the same as those of the first embodiment, and the configuration of the present embodiment can be used in combination with the technique described in the second embodiment.
