摘　　要：本文介绍了为适应HIRFL-CSR(兰州重离子加速器冷却储存环)工程自动化控制现场的通信要求而自主研发的一种通信设备,以及系统硬件电路设计、控制软件设计、工作方式和特点。此设备可快速组建RS485通信网络并且接入以太网,兼容Ethernet、RS232和RS485通信标准协议,特别是增加了光纤接口方便地接入工业光纤通信网络,进一步扩展了其使用范围。此设备在HIRFL-CSR加速器和储存环控制系统中被广泛使用,在使用中表明可满足系统自动控制通信要求。此设备具有实现简单、易于维护、可扩展性好及成本低廉等特点,在其它自动化工业控制领域也有一定的推广空间。A communication equipment-RS485 optical router has been developed to satisfy requirements of control system communication network of HIRFL-CSR （Heavy Ion Research Facility at Lanzhou-Cooling Storage Ring）. The equipment is compatible with multiple communication protocols, such as Ethernet, RS232 and RS485 standard. It can be used to setup the RS485 communication network quickly and connected to the Ethernet easily. The fiber optical interface is introduced to facilitate the connection with the network of industrial Fiber Optics Communication （FOC）, which expands the application field of the equipment in a large extent. This paper introduces the details of the equipment, including the design of the circuit and software, features of the equipment and how it works in the whole control system network. Its application in the HIRFL-CSR control system shows that the equipment is in accordance with the general requirement of automatic control communication system. It could also be used in other industrial automatic control fields.
