摘　　要：为解决泥石流地区河流流量在线监测的难题，本文依据雷达波测速原理，结合泥石流地区云南昆明东川小江水文站测验断面的水文特性，采用非接触式RQ30雷达波传感器等设施设备，实现河流部分表面流速数据采集，采用SIMI（模型计算实时流量，再通过GPRS信道传送到中心站，对数据进行分析处理、存储、转录、发布，实现WEB、手机APP远程实时流量、工况等查询功能。经两年多的运行，系统正常稳定，其监测精度接近巡测站三类精度站要求，可为泥石流地区或山区性河流的流量在线监测提供参考。In order to solve the problem of online monitoring of river flow in debris flow area, based on the principle of radar wave velocimetry, combined with the hydrological characteristics of the test section of the Xiaojiang hydrologic station in Kunming Dongchuan of debris flow area, the RQ30 Radar wave sensor and other facilities are used to realize the velocity data collection of the river part surface. SIMK model was used to calculate real-time traffic, and then transmit to the Center station through the GPRS channel, analyze and process the data, store, transcribe and publish, realize the query function of the web, the mobile phone app＇s long-distance real-time traffic, working condition and so on. After more than two years operation, the system is normal and stable, and its monitoring accuracy is close to the three-type precision station request of the patrol station, which can provide reference for the flow monitoring of river in the debris flow area or mountain river.
