BACnet是一种用于自动化建筑和控制网络的数据通信协议。(Building Automation and Control Networks)
自控网络通信协议基本体系:
CAN -- 只定义了通信标准
BACnet = BAC Model and Message + Network Layer + LANs
The protocol can be viewed as a matrix of layers.
Properties:
Objects:
Devices:
Services:
BIBBS:
1、BACnet Interoperability Building Blocks
2、BIBBS are collections of Services
3、BIBBS define 5 areas of interoperability
总结:
1.Application layer contains the following component:
Properties
Objects
Devices
Services
BIBBs (BACnet Interoperability Building Blocks)
2.Objects have Properties, and are contained within Devices.
3.Devices need Services that implement BA functions and manage the communication transactions.
4.Different device types demand different groups of services. BIBBS define the classes of services and the level of support these services need in each of the device types.
