A Transducer Online Monitor System Based on DSP and Ethernet

根据变频器安全管理的需要,本文设计开发了一套基于DSP和以太网技术的变频器在线监控系统,介绍了它的硬件组成和软件结构。该系统使得变频器与信息网融为一体,实现了对电机当前状态、输出电压、输出电流、当前转速等变频器运行状态数据的实时采集、网络传输、动态显示等功能,并且可以向变频器发出信号来改变电机的当前状态,实验结果证明了该方案的正确性。

According to the security requirements of transducer, a set of transducer online monitor system based on DSP and Ethernet technology is designed. The structure of its hardware and software are presented. The monitoring network integrates the internet perfectly. It can measure several kind of electromotor state information, such as the electromotor state, output voltage, input voltage, current rotate speed, and etc. Further more, Further more, the real-time acquiring、networked transmitting、dynamic displaying are realized. At the same time,the monitor system can also send a signal to the transducer to change current rotate state of electromotor. The practical results have proved the correctness of the design schemes.
