楼宇自动化系统中现场总线的设计

Design of Field Bus in Buildings Automation System

采用控制器局域网总线(CAN)技术,设计楼宇自动化系统(BAS)中的中央空调控制系统.介绍了中央空调控制系统的整体构成,就本系统内的有关总线通信接口及总线控制器进行了设计,主要有现场总线适配器的硬件设计和检测智能节点的软硬件设计.

By use of the technology of controller CAN bus, central air-conditioning control system of buildings automatic system （BAS） is designed. This paper introduces integral structure of the central air-conditioning control system, design of relevant bus communication interface and bus controller in the system, mainly including design of hardware of field bus adapter and design of software ＆ hardware of testing intelligent nodes.
