现场总线应用伴随智能化电器发展

近十年来,由于信息技术领域的飞速发展,带动工业现场总线产品技术极大的提高.从工业现场总线的概念来说,其覆盖的领域极广,包括了上层的计算机管理系统、控制系统、工业机器人、工业现场执行机构和传感器等.现场总线是连接智能化现场设备和控制室之间全数字化、开放的双向的局部通信网络.现场总线种类很多,比较有影响的有:CAN、Lonworks和Profibus等.它们各有特点和优势,在不同领域有不同的应用价值.高压电器设备也不例外.要实现这些智能化的功能就需要现场总线进行通信.

Field-bus application develops along with intelligent electrical appliance

In recent ten years, the information technology develops very fast, which drives the application and improvement of industrial field-bus technology. From the view point of industrial field-bus concept, it covers a very wide area, including the top layer computer management system, control system, industrial robot, industrial field execution device and sensor. The field-bus is the digital, open double-way local communication network connecting the intelligent field equipment and control room. There are various types of field-bus; the most influential ones are CAN, Lonworks and Profibus. They have their respective features and advantages, as well as different application values in different fields. The high voltage electric equipments are not exceptional ones; they also need the communication field-buses to realize their intelligent functions.
