摘要
提出光纤以太网技术代替传统RS-485串口的方案,设计了一种基于光纤以太网的智能数据采集装置,用于数据采集装置和交直流电源系统中监控装置间的通信。基于光纤以太网的智能数据采集装置提高了数据通信的可靠性,减少了监控装置与智能数据采集装置数据交互的时延,提高了运行状况实时反映的能力,同时也为两者之间的数据交换方式提供多种选择,而不仅限制于轮询方式。
This paper proposed to use optical EtherNet technology instead of traditional RS -485 serial port. It designed an optical EtherNet-based smart data acquisition device as the communication of the monitor device between data acquisition device and AC-DC power supply system. This optical EtherNet-based smart data acquisition device improves the reliability of data communication. At the same time, it reduces the interaction time delay between the acquisition device and the monitor system, improves the capability of real-time reflection on running status. Moreover, it provides more options for data exchange methods than polling mode.
