Abstract

A building management system and method are disclosed. The building management system includes: a central control system connected with a network and centrally controlling at least one sub-system accommodated in a building; a multi-air-conditioner system including an outdoor unit and one or more indoor units connected with the outdoor unit; a BACnet gateway serving as a connection passage of the central control system and the multi-air-conditioner system to allow the central control system to centrally control the multi-air-conditioner system; and a remote integrated management server that controls the multi-air-conditioner system by interworking with the BACnet gateway. Because detailed information can be managed through the remote integrated management server, that an existing building management system fails to do, the user convenience can be improved.

Claims

1. A building management system comprising:

a central control system that centrally controls at least one sub-system of a building;

a multi-air-conditioner system;

a BACnet gateway that connects the central control system with the multi-air-conditioner system to allow the central control system to centrally control the multi-air-conditioner system; and

a remote integrated management server that controls the multi-air-conditioner system by interworking with the BACnet gateway.

2. The system of claim 1, further comprising:

an interworking module connected between the BACnet gateway and the remote integrated management server that allows the BACnet gateway and the remote integrated management server to interwork with each other.

3. The system of claim 2, wherein the interworking module comprises:

a data updating unit that periodically updates data;

a data transmission unit that transmits the updated data to the remote integrated management server; and

a protocol unit that connects the data updating unit and the data transmission unit.

4. The system of claim 3, wherein the protocol unit uses an XML (eXtensible Markup Language) protocol to facilitate a variable extension.

5. A building management system comprising:

an interworking module connected between a BACnet gateway and a remote integrated management server that connects a central control system of a building management system with a multi-air-conditioner system, and allows the BACnet gateway and the remote integrated management server to interwork with each other,

wherein the interworking module periodically receives first information data from the multi-air-conditioner system, stores the first information data, and transmits the first information data to the remote integrated management server.

6. The system of claim 5, wherein the first information data comprises information data related to at least one of an indoor unit and a ventilation of the multi-air-conditioner system.

7. The system of claim 5, wherein the interworking module comprises:

a data updating unit that periodically updates data;

a data transmission unit that transmits the updated data to the remote integrated management server; and

a protocol unit that connects the data updating unit and the data transmission unit.

8. The system of claim 7, wherein the protocol unit uses an XML (eXtensible Markup Language) protocol to facilitate a variable extension.

9. A building management method comprising:

periodically receiving and updating first information data of a multi-air-conditioner system;

generating a tag from the received first information data and storing the generated tag; and

transmitting the generated tag to a remote integrated management system.

10. The method of claim 9, wherein the first information data comprises information data related to at least one of an indoor unit and a ventilation of the multi-air-conditioner system.

11. The method of claim 9, wherein the tag is generated by using an XML protocol.
