太湖流域水文遥测系统可靠性分析

Reliability Analysis of Hydrological Data Acquisition System (HDAS) in Taihu Basin

水文遥测系统工作制式不同 ,系统的验收标准也不同 .水文遥测系统的组网结构不同 ,系统可靠性的分析方法也不同 .本文用概率方法对太湖流域水文遥测系统的可靠性进行探讨 ,对带存储功能的应答系统采用系统可靠度衡量 ,而不采用月平均数据畅通率衡量 ;同时讨论不同的系统结构对可靠性的影响 .这种以概率统计的方法分析水文遥测系统的可靠性 ,对水文遥测系统建设的验收标准制定和水文遥测系统结构设计具有重要意义 .

The checking and accepting standards of Hydrological Data Acquisition System (HDAS) construction vary with its work mode. The analytical methods of HDAS reliability could be different under different structures. The reliability of the built up of HDAS in Taihu Basin is discussed in this paper by means of probability analysis. The reliability is better to measure the polling answering system with memory than the accessible rate of a monthly average, and the reliability has been influenced by the system structure. It is of great significance that the reliability of HDAS is studied by the probability statistics on the draft of checking and acceepting standards of the system construction and the structure design of HDAS.
