摘　　要：针对山区河流在监测悬浮泥砂含量过程中缺乏实时性的问题,研发了山区河流流量及悬浮泥砂含量自动监测装置。研发中,基于堰槽组合结构设计流量及悬浮泥砂含量监测试验,建立了水位-流量及浑浊度-悬浮泥砂含量模型关系式,利用C语言将2种模型关系式编译写入单片机,设计测量模块、数据存储显示模块及供电模块。实地测试结果表明,该仪器监测的流量相对误差<3%,悬浮泥砂含量相对误差<10%,可以实现连续监测河流流量及悬浮泥砂含量动态变化过程。In response to the lack of real-time monitoring of suspended sediment content in mountainous rivers,an automatic monitoring device for flow and suspended sediment content in mountainous rivers was developed.Flow and suspended sediment content experiments were conducted based on the design of weir-combination structure,and the relationship models of water level-flow and turbidity-suspended sediment content were analyzed and established.The two model relationships were compiled and written into a single-chip microcomputer using C language.Measurement module,data storage display module,and power supply module were designed.Field test results showed that the relative error of the instrument's monitored flow is less than 3%,and the relative error of suspended sediment content is less than 10%,indicating the ability to continuously monitor the dynamic changes in flow and suspended sediment content in rivers.
