中文摘要：
风电是中国未来10年发展洁净新能源重要项目,要掌握机组的运行状态、及时排除机组故障而减少不必要的停机和事故,一套在线监测系统就显得尤其重要。基于Zig Bee和以太网技术研究了一套数据采集和传输系统,对数据采集模块、数据传输模块进行了硬件和软件设计,并完成了Zig Bee网络和以太网网络之间的协议转换,实现了数据的双向传输,并用简单的试验证明了该系统的可靠性很高。该系统有安装简单、低复杂度、安全性高、低成本等优点。解决风电场尤其是海上风力发电场的布线困难、不方便维修、成本高等困难,同时也为数据采集点多、布线复杂的在线监测系统提供了新的思路。
英文摘要：
Wind power is an important project for developing clean energy in the next ten years in China,in order to master the operating condition of the unit and remove the unit failures promptly so as to reduce the unnecessary outage and accidents,a set of on- line monitoring system is becoming more important. Based on Zig Bee and Ethernet technology,a set of data acquisition and transfer system is developed,and the hardware and software of data acquisition module and data transfer module are designed. By completing the protocol conversion between Zig Bee and Ethernet network,the bidirectional data transfer is achieved and its higher reliability is proved by simple tests. The system is easy to be installed,and has such advantages as low complexity,high security and low cost etc. It not only solves many difficulties of wind farm,especially offshore wind farms,such as difficult wiring,inconvenient maintenance and high cost,but also provides a new idea for on- line monitoring system with many data acquisition points and complex wiring.
