摘要
为了对风电机组实时远程监控并实现分布式网络化管理,设计了一种基于ARM嵌入式系统的风电机组振动监测系统。系统有24通道的模拟信号采集电路,并借助于FPGA对周围电路进行逻辑控制和数据的实时采样;FPGA与ARM通信应用EDMA技术,极大提高了数据传输速率,可满足高速率采样的数据传输要求;此外,上位机与目标板之间的数据通信采用TCP/IP协议。通过实验观察上位机输出结果,验证了数据的实时性和准确性,达到了对风电机运行的状态信息监测和故障诊断的要求。
To realize real-time monitoring and distributed network management,a wind turbines vibration monitor-ing system based on ARM embedded system was designed. The system includes 24 channels of analog signal acqui-sition circuit,the FPGA is applied to realize the logic control of the peripheral circuit including real-time sam-pling of data;to meet data transmission requirement for high speed sampling,the EDMA technology is adopted toaccess the data communication between FPGA and ARM,which extremely improve the data transmission rate;besides,TCP/IP protocol is used in the data communication between the object board and the upper computer. Testresults verify the real-time and accuracy of data,and indicate that it reaches the requirements of the state monitor-ing and fault diagnosis of the wind turbines.
