摘要
针对电网电压的监测,通过交、直流采样方法对比,选用交流采样方法,设计开发了智能型电网电压监测仪,详细介绍了系统的硬件和软件设计。该系统有效减少了采样中的非线性环节,提高了采样精度,设计的仪表可实现单台独立工作,也可通过与PC机通讯,进行集中监控,适用于工业用电量采集等应用场合。
Aiming at power network voltage monitoring,this paper uses the methods of AC/DC sampling by contract the two methods.An intelligent power network voltage monitor is designed and developed.The system hardware and software design are introducted in detail.The system effectively reduces the section of the nonlinear sampling improves the sampling precision. The designed instrument achieves single work independently,the PC machine communications is centralized monitoring.The instrument is used for industrial electricity collection applications.
