花园口水文站水位遥测系统及其在水文测报中的应用

花园口水文站水位遥测系统是一套适于黄河水沙特性、能监控花园口测验河段纵横向水位变化的自动测报系统。系统采用无线自报式工作方式 ,包括 12处遥测站点、1处中心接收控制站、2处中继站和 3处领导单位接收系统。野外的 12处遥测站点分布在上至邙山、下到辛寨的 5 0km河段范围内。在花园口水文站的中心机房可随时查阅该河段内的水位信息。采用水位遥测系统具有以下优点 :第一 ,可以监测、控制较长河段的洪水位演变情况 ;第二 ,遥测水位资料连续完整、及时可靠 ,可弥补人工定时观测的不足 ;第三 ,可为本站掌握测验时机和合理布置流量测次争取主动 ;第四 ,可为本站测验河段横比降的研究提供实时观测数据。

Water Level Remote Survey System in Huayuankou Hydrological Station and Its Application in Hydrological Prediction

Water level remote survey system of Huayuankou Hydrological Station is a set of automatic survey and forecast system applicable to the Yellow River flow and sediment characteristics and able to monitor and control water level changes across and along the river in Huayuankou reach. Adopted radio automatic record method, the system includes 12 remote survey sites and stations, 1 central receive and control station, 2 transmit stations and 3 leading unit receiving systems. Twelve remote survey sites and stations are located in the field of 50 kilometers distance up to Mangshan and down to Xinzhai. Water level data in the 50 kilometers distance can be read and checked at anytime in the central control room of Huayuankou station. There are following advantages by using the water level remote survey system: first, water level evolution during a flood in a comparatively long reach monitored and controlled; second, remote surveyed water level data is in time, continuous, and reliable, which can make up for the deficiency of personal observing error; third, easy to control the time to make reasonable distribution of discharge measurements; fourth, provide actual observed data for the station study of lateral river gradient in the reach.
