Abstract

A device control determiner outputs a control information request containing a condition of facility devices in a data possessing device group possessing control information, and a kind of the control information. A connection relationship manager manages information regarding a connection relationship among each of the plurality of facility devices. A connection route database stores information regarding a connection route from a reference device that is a reference among the plurality of facility devices to another facility device. The device grouper creates a data possessing device group based on the control information request, the connection route database and information managed by the connection relationship manager. An information collective obtainer obtains control information from the facility device in the data possessing device group through a communicator, and creates a data array of the obtained control information.

First claim

The invention claimed is:

1. A control device that controls a plurality of facility devices, the control device comprising:
a communicator that receives control information from each of the plurality of facility devices;
a control determiner that outputs a control information request for collectively obtaining pieces of the control information, the control information request containing a condition of the facility devices to be included in a possessing device group possessing the control information, and a kind of the control information;
a connection relationship manager that manages information on a connection relationship among the plurality of facility devices;
a connection route database that stores information on a connection route from a reference device in the plurality of facility devices to another facility device;
a device grouper that creates the possessing device group based on the control information request, the connection route database, and information managed by the connection relationship manager; and
an information collective obtainer that creates a data array of the control information received by the communicator from the facility device in the possessing device group, wherein:
the connection route database stores a condition on a connection relationship, an attribute of the reference device, and a sequence order of an attribute of the facility device from the reference device in association with one another, the sequence order being information on the connection route;
the control information request contains, as the condition of the facility devices to be included in the possessing device group, a connection relationship between the reference device and the facility devices to be included in the possessing device group;
the device grouper traces the sequence order of the attribute of the connection route obtained from the connection route database based on the connection relationship contained in the control information request to specify the facility device to be included in the possessing device group;
the control information request further contains a condition of the facility devices to be included in a managed device group to be managed;
the control device further comprises a data mapper that
allocates an element of a data array of the control information created by the information collective obtainer to any of the facility devices in the managed device group to create a control information set and
outputs the created control information set to the control determiner;

the device grouper creates the managed device group and the possessing device group having the facility device in the managed device group as the reference device based on the control information request, the connection route database, and information managed by the connection relationship manager; and
the control determiner controls the reference device based on the control information set created by the data mapper.

2. The control device according to claim 1 , wherein:
the connection relationship manager:
comprises a connection destination database in which an attribute of each the facility device and an attribute of the facility device directly connected with the each facility device are associated with each other; and
returns the attribute of the facility device directly connected to the facility device inquired by the device grouper by referring to the connection destination database; and

the device grouper traces a sequence order of an attribute of the connection route based on the attribute of the facility device returned from the connection relationship manager.

3. The control device according to claim 1 , wherein the connection route database includes a stored content updatable through an external device.

4. The control device according to claim 1 , wherein when plural pieces of control information are allocated to any one of the facility devices in the managed device group, the data mapper allocates, as the control information of the facility device to which the plural pieces of control information are allocated, a representative value of the plural pieces of control information or a calculated value obtained by calculating the plural pieces of control information allocated.

5. The control device according to claim 1 , further comprising:
a numerical operator that performs a numerical operation based on the control information of the two possessing device groups received from the control determiner, and an operation instruction, and that returns the operation result to the control determiner; and
a data reformer that reforms the control information of the one possessing device group in such a way that the connection relationship of the facility device corresponding to each element of the control information of the possessing device group satisfies a predetermined condition,
wherein the numerical operator performs the numerical operation using the control information reformed by the data reformer.

6. The control device according to claim 5 , wherein the data reformer:
causes the device grouper to create a connected device group in a predetermined connection relationship with the facility device in the one possessing device group; and
when the other possessing device group contains the facility device of the connected device group, stores the control information in a same location in an array as a sequence order of the facility device in the other possessing device group to create an array of the control information of the one possessing device group.

7. The control device according to claim 1 , further comprising:
an installation relationship database that stores a grouping condition related to a positional relationship of installation locations, and information indicating a search route to search the facility device satisfying the grouping condition in association with each other; and
an installation relationship manager that manages information on a relationship between the plurality of facility devices and installation locations thereof,
wherein the grouper groups the facility device satisfying the grouping condition based on the installation relationship database and information managed by the installation relationship manager.

8. The control device according to claim 7 , wherein:
the search route is a route formed by a connection between the installation location and the facility device; and
the device grouper:
searches, when an element of the search route associated with the grouping condition in the installation relationship database indicates an installation location, the facility device located at the installation location, and creates an installation related device quasi-group;
leaves, when the element of the search route associated with the grouping condition in the installation relationship database indicates an attribute of the facility device, only the element matching the attribute in the installation related device quasi-group; and
groups the facility devices included in the installation relationship device quasi-group at a time point at which the search route is traced to an end.

9. The control device according to claim 7 , wherein the device grouper:
performs grouping based on a connection relationship of the facility device upon receiving a group creation instruction of grouping based on the connection relationship of the facility device; and
performs grouping based on an installation relationship of the facility device upon receiving a group creation instruction of grouping based on the installation relationship of the facility device.

10. An air conditioning system comprising:
the control device according to claim 1 ; and
a plurality of air conditi
