摘　　要：为了方便把自动化设备直接连到LonW orks总线上,提出了一种总线连接器的设计方案。该总线连接器是由LonW orks总线接口、单片机/Neuron芯片主从通信接口和应用接口3个部分构成的AnyBus-S模块,主要通过该功能模块中的双口RAM来实现LonW orks总线和外设之间的数据交换及总线对外设的控制。AnyBus-S模块内部固化了LonTalk协议,可直接把外设连接到LON总线上。实践证明,AnyBus-S模块是使设备与LonW orks总线互连的最佳方法之一,也是在智能节点构造中具有较高应用实效的设备。In order to connect automation equipment to the LonWorks directly,a schemc to design a fieldbus connector is proposed. This fieldbus connector is an AnyBus - S module composed of a LonWorks bus interface,a communication interface of MCU / Neuron Chip and an application interface. Dual port RAM in this function module realizes the data exchange between LonWorks and the peripheral hardware, and the controlling of LonWorks to the peripheral hardware. The LonTalk protocol is solidified in the AnyBus - S module, so the peripheral hardware can be applied to LON bus expediently. Experimental results prove that the AnyBus - S module is one of the best methods of interconnecting the peripheral and the bus, and it is good equipment which has applicable effect in the intellectual node building.
