Abstract

Disclosed is a building management system which includes a BACnet gateway including a protocol converter which receives data in a remote communication protocol format and converts the data according to a BACnet communication protocol, a central controller which connects to the BACnet gateway and controls a sub-system of a building, and a watt-hour meter which measures a wattage of the sub-system and transmits wattage data to the protocol converter using the remote communication protocol format.

Claims

1. A BACnet gateway, comprising:

a protocol converter which receives data in a remote communication protocol format, and converts the data according to a BACnet communication protocol.

2. A BACnet gateway according to claim 1, further comprising a port which receives digital pulse signals.

3. A BACnet gateway according to claim 1, wherein the remote communication protocol is an RS-485 communication protocol.

4. A building management system, comprising:

a BACnet gateway comprising a protocol converter which receives data in a remote communication protocol format, and converts the data according to a BACnet communication protocol;

a central controller which connects to the BACnet gateway and controls a sub-system of a building; and

a watt-hour meter which measures a wattage of the sub-system and transmits wattage data to the protocol converter using the remote communication protocol format.

5. A building management system according to claim 4, wherein the remote communication protocol is an RS-485 communication protocol.

6. A building management system according to claim 4, wherein the BACnet gateway further comprising a port which receives digital pulse signals.

7. A building management system according to claim 6, further comprising a watt-hour meter which measures a wattage of a sub-system of the building and transmits wattage data to the port using digital pulse signals.

8. A method of managing building sub-systems, comprising:

measuring, by a first watt-hour meter, a wattage of a building sub-system;

transmitting wattage data of the first watt-hour meter to a protocol converter of a BACnet gateway using a remote communication protocol;

converting the wattage data to a BACnet communication protocol; and

transmitting the converted wattage data to a central controller.

9. A method according to claim 8, further comprising controlling the sub-system, by the central controller, based on the converted wattage data.

10. A method according to claim 8, further comprising measuring, by a second watt-hour meter, a wattage of a building sub-system;

and

transmitting wattage data of the second watt-hour meter to a port of the BACnet gateway using digital pulse signals

11. A method according to claim 8, wherein the remote communication protocol is an RS-485 communication protocol.
