A Pharos CAD system was proposed, in which the expert system and the parts family are adopted.

提出了一种结合专家系统、零件族库实现基于产品配置的灯桩CAD系统的方法。

We collect the information about the position by GPS and the working state of pharos, then we can monitor and control pharos using the technology of GIS.

将GPS获得的位置信息以及传感器获得的航标工作状态通过专线传回，结合GIS技术对航标进行监控。

Background monitoring system is composed of YanHua industry control machine and PCI based data boards which guarantees the sampling data reliability and implements the real time pharos calculation.

数据采集系统平台由研华工控机及基于PCI接口的数据板卡组成，实现了可靠的数据采集和实时相量测量。
