Description

Communication system for building management, communication method for building management, and communication server for building management

The present invention relates to a building management communication system, a building management communication method, and a building management communication server, and more particularly, a relay device such as a router addresses a building-side server installed for each building or each room of the building. The present invention relates to a building management communication system that dynamically assigns information, a building management communication method using the system, and a building management communication server constituting the system.

In recent years, a so-called HEMS (Home Energy Management System) system that controls energy usage equipment in a house through a home server installed in a house and visualizes the energy usage status in the house has been attracting attention. Some home servers are communicably connected to a center server via a network such as the Internet. This center server provides services such as distributing home server application programs (hereinafter referred to as bundles) to the home server. Then, by using the service provided by the center server, the home server can provide various benefits to the resident of the house that is the user, in particular, benefits related to the energy usage management of the house. .

By the way, in order to smoothly communicate between the home server and the center server, it is necessary for each to recognize the address information of the other party, for example, the IP address. Regarding IP addresses, there are fixed addresses and variable addresses, and when fixed addresses are used, it becomes impossible to deal with when the stock of fixed addresses is exhausted. Therefore, normally, a home server is assigned a variable address as an IP address. On the other hand, the center server dynamically manages the IP address of the home server. For this reason, some center servers receive notification from the home server regarding IP address information (see, for example, Patent Document 1).

In Patent Document 1, an OSGi client corresponding to a home server has means for notifying an OSGi server corresponding to a center server of IP address information, and the OSGi server stores IP address information received from the OSGi client. Means are provided. As a result, in the system described in Patent Document 1, even when there are a large number of OSGi clients, the OSGi client address can be easily registered and managed on the OSGi server side.

The service management table T2 may include information on the bundle transmission service being used by the user other than the service ID and the transmission completion flag, for example, version information of each bundle installed in the home server 1. .

Furthermore, the smart house database 13 may store table information other than the two tables T1 and T2. For example, table information indicating the correspondence between the service ID of each plan and the type of bundle transmitted when the plan is applied may be stored.

Next, the configuration of each device in the system S will be described from the functional aspect with reference to FIG.
The home server 1 includes a server status notification unit 31, an address notification unit 32, a home server storage unit 33, and an IP address acquisition unit 34.
The home server storage unit 33 corresponds to a building-side server storage unit and includes the memory of the home server 1. The home server storage unit 33 stores the IP address assigned by the router 2 and the type and version information of the bundle currently installed in the home server 1. The IP address acquisition unit 34 acquires an IP address assigned by the router 2 and stores it in the home server storage unit 33, and includes an interface provided in the home server 1 for recognizing the router 2.

The server status notification unit 31 notifies the server status information to the remote monitoring server 10, and is configured by a CPU of the home server 1, a memory, a communication interface, and a communication bundle mounted on the home server 1. Yes. In the present system S, the server status notification unit 31 notifies the remote monitoring server 10 of server status information regularly, specifically every hour. In other words, the remote monitoring server 10 periodically performs alive monitoring. When the status of the home server 1 is communicable with the remote monitoring server 10 during life and death monitoring, the server status notifying unit 31 notifies server status information indicating that fact. The server status information to be notified includes information indicating the type and version of the bundle installed in the home server 1 as described above.

The address notification unit 32 reads the IP address stored in the home server storage unit 33 and notifies the remote monitoring server 10 of the read IP address. The address notification unit 32 includes a CPU of the home server 1, a memory, a communication interface, and a communication bundle mounted on the home server 1.
In the system S, the address notification unit 32 notifies the remote monitoring server 10 of the IP address when the server state notification unit 31 notifies the server state information. That is, in the present system S, the IP address is notified to the remote monitoring server 10 together with the server status information in the alive monitoring process that is periodically executed. As described above, since the remote monitoring server 10 receives the IP address together with the server status information when executing the alive monitoring process, the communication load is reduced as compared with a case where separate communication is performed to receive the IP address. It will be.

The user terminal 7 includes an operation reception unit 41, a data generation unit 42, a terminal side transmission unit 43, and a terminal side reception unit 44. The operation receiving unit 41 includes an input device (not shown) (for example, a touch panel) included in the user terminal 7 and receives a user input operation. When the operation receiving unit 41 receives a user input operation, the data generation unit 42 generates input data indicating the content input by the user in the input operation. Note that the data generation unit 42 includes a CPU of the user terminal 7, a memory, and a program installed in the user terminal 7.

The terminal-side transmission unit 43 requests data transmission to a device that is a communication partner through the in-home network 8 and the out-of-home network 9. For example, when the operation receiving unit 41 receives a predetermined input operation, the data generating unit 42 generates data for requesting data transmission as input data, and the terminal-side transmitting unit 43 sends the data to the outside It transmits to the AP server 11 through the network 9.
The terminal-side receiving unit 44 receives various data through the in-home network 8 and the out-of-home network 9, for example, receives address data described later from the AP server 11 through the out-of-home network 9. The terminal-side transmission unit 43 and the terminal-side reception unit 44 are configured by the CPU of the user terminal 7, the memory, the communication interface, and a communication program installed in the user terminal 7.

The remote monitoring server 10 includes an acquisition unit 51, a delivery unit 52, a reading unit 53, and a bundle transmission unit 54, which include a CPU, a memory, a communication interface, and remote monitoring of the remote monitoring server 10. The communication program is installed in the server 10.
The acquisition unit 51 acquires the server status information notified by the server status notification unit 31 of the home server 1 and the IP address notified by the address notification unit 32 when executing the alive monitoring process. As described above, in the present system S, when the server status information is notified from the home server 1 in the alive monitoring process that is periodically executed, the acquisition unit 51 is notified together with the notification of the server status information. Obtain an IP address. That is, in the system S, the acquisition unit 51 simultaneously acquires the IP address of the home server 1 when acquiring the server state information of the home server 1.

The delivery unit 52 delivers the server state information and IP address acquired by the acquisition unit 51 to the AP server 11. The reading unit 53 accesses the bundle storage database 14 and reads the bundle transmitted by the bundle transmission unit 54. The bundle transmission unit 54 corresponds to a program transmission unit, and transmits the bundle read by the reading unit 53 from the bundle storage database 14 to the home server 1.

The AP server 11 includes an address data transmitting unit 61, a writing unit 62, a bundle transmission requesting unit 63, an IP address receiving unit 64, and a server state information receiving unit 65. These are the AP server 11 CPU, memory, communication interface, and communication program installed in the AP server 11.

The IP address receiving unit 64 receives the IP address delivered from the delivery unit 52 of the remote monitoring server 10, and the server status information receiving unit 65 receives the server status information delivered from the delivery unit 52.

The writing unit 62 corresponds to a storage processing execution unit, and executes processing for storing the information received by the IP address receiving unit 64 and the server state information receiving unit 65 in the smart house database 13. In other words, the information received by the IP address receiving unit 64 and the server status information receiving unit 65 corresponds to the information acquired by the acquisition unit 51 of the remote monitoring server 10, so the writing unit 62 is the information acquired by the acquisition unit 51. It can be said that the process of storing the data in the smart house database 13 is executed.

The writing unit 62 will be described more specifically. The writing unit 62 specifies the source of the information from the information received by the IP address receiving unit 64 and the server status information receiving unit 65. Thereafter, the writing unit 62 reads the server information management table T1 stored in the server information storage area 13b of the smart house database 13, and searches the table T1 for client identification information corresponding to the specified information source. Then, the writing unit 62 rewrites the IP address and server status information (specifically, the last online date and time) associated with the searched client identification information with the latest information. The latest information is information most recently received by the IP address receiving unit 64 or the server status information receiving unit 65.

Also, the writing unit 62 can read the service management table T2 stored in the service information storage area 13a in the smart house database 13 and rewrite the transmission completion flag in the table T2. For example, when all bundles that can be transmitted at the present time are transmitted by the bundle transmission unit 54 among the bundles corresponding to each plan, the writing unit 62 sets the transmission completion flag to ON. On the other hand, when there is an untransmitted bundle due to reasons such as adding a new bundle, the writing unit 62 sets the transmission completion flag to OFF.

In response to a data transmission request from the user terminal 7, the address data transmission unit 61 reads the IP address in the server information management table T1 from the server information storage area 13b in the smart house database 13, and an address indicating the read IP address Data is transmitted to the user terminal 7. On the user terminal 7 side, the address data is received, and the IP address indicated by the address data is displayed on the display screen. As a result, the user can check the IP address currently used by the home server 1 owned by the user.

In the system S, the AP server 11 is implemented with an API that is used when the user terminal 7 requests the address data transmission unit 61 to transmit address data. For this reason, the user can easily obtain the address data by using the API when requesting the AP server 11 to transmit the address data through the user terminal 7.

More specifically, with reference to FIG. 5, the user performs a predetermined input operation through the user terminal 7 when requesting the AP server 11 to transmit address data. Here, the predetermined input operation is an input operation required to use an API for requesting transmission of address data out of APIs provided by the AP server 11, for example, an address bar on the browser screen. Is an operation of inputting a character string (so-called request URL) indicating the URL of the AP server 11 or the like. When the above input operation is accepted by the user terminal 7, the terminal-side transmission unit 43 of the user terminal 7 transmits an address data transmission request to the AP server 11.
The transmission of the address data transmission request is not limited to the case where the user's input operation is accepted. For example, it may be automatically performed when a predetermined application program is started on the user terminal 3 side. Good.

When the AP server 11 receives the data transmission request via the outside network 9, the address data transmission unit 61 specifies the home server 1 that is the transmission source from the data transmission request. Thereafter, the address data transmission unit 61 reads the identified IP address of the home server 1 from the server information management table T1 stored in the server information storage area 13b of the smart house database 13. Then, the address data transmission unit 61 transmits address data indicating the read IP address to the user terminal 7.

The bundle transmission request unit 63 corresponds to a program transmission request unit, and requests the bundle transmission unit 54 to transmit a bundle. The bundle transmission request unit 63 periodically reads the service management table T2 stored in the service information storage area 13a of the smart house database 13 and determines whether the transmission completion flag is on or off. Then, the bundle transmission request unit 63 identifies the client identification information corresponding to the transmission completion flag turned off, and identifies the home server 1 and the service ID from the identification information. The identified home server 1 corresponds to a transmission destination when the bundle transmission unit 54 transmits a bundle.
Note that the on / off determination of the transmission completion flag is not limited to the periodic execution, and may be performed, for example, when a new bundle is added to the bundle storage database 14.

Thereafter, the bundle transmission request unit 63 specifies a plan from the specified service ID, and further specifies a bundle corresponding to the specified plan. The identified bundle corresponds to a transmission target candidate transmitted to the home server 1 by the bundle transmission unit 54. Then, the bundle transmission request unit 63 identifies an unmounted bundle that is not mounted on the home server 1 specified as the bundle transmission destination among bundles that are candidates for transmission, and sets the unmounted bundle as a transmission target. .

The bundle transmission request unit 63 refers to correspondence data indicating the correspondence between each plan and the bundle transmitted when the plan is applied when specifying the bundle corresponding to the specified plan. The correspondence data may be stored in the memory of the AP server 11 or may be stored in the smart house database 13.

The bundle transmission request unit 63 notifies the bundle transmission unit 54 of the bundle transmission unit 54 after notifying the bundle transmission unit 54 of the home server 1 specified as the transmission destination and the bundle set as the transmission target. As a result, the bundle transmission unit 54 transmits the bundle specified as the transmission target to the home server 1 specified as the transmission destination in response to the request from the bundle transmission request unit 63.

As described above, in the present system S, the bundle transmission requesting unit 63 transmits to the bundle transmitting unit 54 only the bundle corresponding to the plan applied by the user among the bundles stored in the bundle storage database 14. Request. Thereby, the configuration of the bundle mounted on the home server 1 becomes a configuration according to the plan applied by the user. Therefore, when the home server 1 is shipped, it is possible to prevent unnecessary bundles that are not desired by the user from being installed in the home server 1 due to all the bundles that can be installed in the home server 1 being installed in the home server 1. It becomes.

In the present system S, when there is an unmounted bundle that is not mounted on the home server 1, that is, when the transmission completion flag is off, the bundle transmission request unit 63 is not directed toward the home server 1. The installed bundle was automatically sent. Thereby, for example, when there is a bundle that can be upgraded by updating the bundle already installed in the home server 1, the bundle for update is transmitted to the home server 1, and the bundle is automatically upgraded. Has been made. However, the present invention is not limited to this. When the AP server 11 requests the user's permission for bundle transmission and there is permission, that is, when the AP server 11 receives data indicating that the user has permitted bundle transmission. It is good also as sending a bundle only to.

Next, an example of a building management communication method using the system S (hereinafter, this communication method) will be described with reference to FIGS.
This communication method is applied when a service provided by the center server group to the home server 1 is executed, specifically, when the above-described alive monitoring service or bundle transmission service is executed.

First, the life and death monitoring service will be described. As shown in FIG. 6, when a predetermined time has passed since the last life and death monitoring (Yes in S001), the remote monitoring server 10 sends server status information to the home server 1. Request transmission (S002). Thereafter, when the home server 1 receives the above request via the outside network 9 (S003), the server status notification unit 31 of the home server 1 sends the server status information to the remote monitoring server 10 in response to the request. Notification is made (S004).

In this communication method, when the server status notification unit 31 notifies the server status information to the remote monitoring server 10, the address notification unit 32 reads and reads the IP address stored in the home server storage unit 33. The remote monitoring server 10 is notified of the IP address.
Of course, as a premise that the address notification unit 32 notifies the remote monitoring server 10 of the IP address, the IP address dynamically assigned by the router 2 is stored in the home server storage unit 33 in the previous stage of alive monitoring. The process has already been implemented.

The server status information and the IP address notified from the home server 1 are received by the remote monitoring server 10 via the outside network 9 (S005). In other words, in the remote monitoring server 10, the acquisition unit 51 acquires the server status information and the IP address notified from the home server 1. Thereafter, the server status information and the IP address acquired by the acquisition unit 51 are delivered to the AP server 11 by the delivery unit 52 of the home server 1 (S006).

In the AP server 11, each of the IP address receiving unit 64 and the server status information receiving unit 65 receives information from the remote monitoring server 10 (S007), and the writing unit 62 stores the received server status information and IP address in the smart house. The data is written in the server information storage area 13b of the database 13 and stored in the area (S008). As a result, the server information management table T1 stored in the server information storage area 13b is updated.
Then, when there is a transmission request for an IP address from the user terminal 7 to the AP server 11, the address data transmission unit 61 of the AP server 11 is stored in the server information storage area 13b of the smart house database 13 to respond to the request. Read the IP address. Further, the address data transmission unit 61 transmits address data indicating the read IP address data to the user terminal 7. As a result, on the user terminal 7 side that has received the address data, the IP address indicated by the address data is displayed.

Next, the bundle transmission service will be described. As shown in FIG. 7, first, in the AP server 11, the bundle transmission request unit 63 stores the service management table T2 stored in the service information storage area 13a of the smart house database 13. Reading (S011), it is determined whether the transmission completion flag is on or off (S012).

When the transmission completion flag is off, the bundle transmission request unit 63 specifies client identification information corresponding to the transmission completion flag that has been turned off. In addition, the bundle transmission request unit 63 specifies the home server 1 as the bundle transmission destination and the service ID indicating the plan applied by the user who is the owner of the home server 1 based on the specified client identification information. Further, the bundle transmission request unit 63 specifies a plan from the specified service ID, and then specifies a bundle corresponding to the plan. Further, an unmounted bundle that is not mounted on the home server 1 that is the bundle transmission destination is identified from the identified bundles, and the unmounted bundle is set as a transmission target bundle (S013).

Thereafter, the bundle transmission request unit 63 notifies the remote monitoring server 10 of the home server 1 specified as the transmission destination and the bundle set as the transmission target, and then requests bundle transmission (S014).

On the other hand, when the remote monitoring server 10 receives a bundle transmission request from the AP server 11 (S015), the bundle transmission unit 54 selects the AP server as a transmission target bundle from the bundles stored in the bundle storage database 14. The bundle notified by 11 is read (S016). Then, the bundle transmission unit 54 transmits the read bundle to the home server 1 notified by the AP server 11 as a transmission destination (S017). When the bundle transmitted by the bundle transmitting unit 54 is received by the destination home server 1 via the outside network 9 (S018), the bundle is installed (installed) in the home server 1.

When the bundle transmission by the bundle transmission unit 54 is completed, a notification indicating that is sent to the AP server 11. On the side of the AP server 11, the writing unit 62 accesses the service information storage area 13 a of the smart house database 13 when the notification is received. Then, the writing unit 62 identifies the client identification information corresponding to the home server 1 for which the bundle transmission has been completed in the service management table T2 stored in the service information storage area 13a, and can be transmitted in association with the client identification information. The flag is turned on (S020).

It is not intended to limit the invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents thereof.

In the above-described embodiment, the bundle transmission request unit 63 requests the bundle transmission unit 54 to transmit only the bundle corresponding to the plan applied by the user among the bundles stored in the bundle storage database 14. It was decided. Thereby, in the above embodiment, the configuration of the bundle mounted on the home server 1 is configured according to the plan applied by the user, and the bundle not corresponding to the plan is not mounted on the home server 1. . However, the present invention is not limited to this, and all bundles that can be mounted on the home server 1 may be transmitted to the home server 1 regardless of the type of plan.

In the above embodiment, the building management communication server is a center server group including a plurality of center servers. However, the present invention is not limited to this, and a configuration in which a single center server is provided as a building management communication server, that is, a center that combines the functions of the remote monitoring server 10 and the AP server 11 described above.
