摘　　要：葛洲坝二江泄水闸扬压力自动化系统于２０００年６月实施完成。测压传感器采用美国Ｇｅｏｋｏｎ公司 ＧＫ４５００５－５０型振弦式仪器，数据采集设备及数据管理系统为南京南瑞集团公司大坝及工程监测公司产品。经过试运行及与人工比测．认为自动化系统稳定性和精度指标都较好，达到取代人工现测的目的。The automatic uplift pressure, monitoring system at Gezhouba Erjiang spillway was completed in June. 2000. The vibrating wire sensor GK4500S-50 made in Geokon Co.. U. S. A is used as pressure transmitter, and the data acquisition equipment and data management system are the products of NARI Co.. Nanjing. According to the trial operation and manual measurement, it can be believed that the stability and accuracy of the automatic system are both better than that of the manual system, so the manual system can be replaced by the automatic system.
