Simultaneous connectivity and management across multiple building automation system networks
A building automation system (BAS) network manager supporting a plurality of device protocols coupled to at least one communication network, and a plurality of logical connections to individual BAS networks to multiple end devices of a BAS. The BAS network manager can communicate with each of the end devices regardless of the protocol or protocol version of the BAS network by implementing a protocol stack above the link layer for each protocol or protocol version, providing an integrated multi-BAS network interface, and maintaining a device identifier for each BAS network the network manager is coupled to in the protocol stack.
1. A method of integrating a plurality of building automation system (BAS) networks comprising:
communicatively coupling each of the plurality BAS networks to a central server engine;
configuring the server engine to communicate with each of the plurality of BAS networks by providing a protocol stack for a BAS network protocol compatible with at least one of the plurality of BAS networks;
storing a BAS network device identifier associated with the server engine for the at least one of the plurality of BAS networks in the protocol stack; and
storing a device address binding table including the BAS network address of each of a plurality of devices connected to each of the plurality BAS networks in the protocol stack for each of the plurality of BAS networks.
2. The method of claim 1 , wherein the at least one of the plurality of BAS networks is a BACnet compatible network.
3. The method of claim 1 , wherein the central server engine is communicatively coupled to the at least one of the plurality BAS networks by an interne protocol compatible network.
4. The method of claim 3 , wherein the internet protocol compatible network is the Internet.
5. A method for managing a plurality of building automation systems (BAS) having at least two incompatible building automation system networks comprising:
communicatively coupling the at least at least two incompatible building automation system networks to an router configured to encapsulate data traffic from each of the at least at least two incompatible building automation system networks onto a third network;
communicatively coupling a building automation system network manager engine to the third network;
parsing the data traffic from each of the at least two incompatible building automation system networks into at least two separate network level protocol stacks;
storing a network device identifier associated with the building automation system network manager engine in each of at least two separate network level protocol stacks; and
storing a device address binding table including a network address of each of a plurality of devices connected to each of the least two incompatible building automation system networks in each of at least two separate network level protocol stacks.
6. The method of claim 5 , wherein at least one of the at least two incompatible building automation system networks is a BACnet compatible network.
7. The method of claim 5 , wherein the third network is an interne protocol compatible network.
