摘要
详述数字电极的系统构成、电路结构、通信协议和其他关键技术。该系统的通信网络结构基于RS-485现场总线,通过环境测试和台站试验,发现数字电极技术适用于多极距电阻率系统。
On the basis of earth resistivity technology, a digital multi-spacing system for apparent resistivity observation from the digital electrode is presented in this paper. Besides, a more detailed discussion of the circuit structure, system structure, control, communication protocol of the digital electrode and other key technologies are also given in the paper. The system＇s communication network structure is based on the RS-485 field bus components. Performance testing and station texting indicate that the digital electrode is suitable for a multispacing system of apparent resistivity observation.
