摘要
近年来,非接触式明渠水流监测技术在传感器及嵌入式技术的推动下取得了很大进步,基于声学、光学、电波及图像的测流仪器显著提高了水文测验及水利量测的效率及安全性。分析几种非接触式测流仪器的原理、性能及适宜性,以水文测验和水利工程为背景提出现代明渠水流监测技术的应用需求,指出多源传感器信息融合技术的应用是新技术的发展方向,研发具有我国自主知识产权的核心技术和仪器设备是当前经济社会发展和河流相关科学研究的迫切需求。
In recent years, the non-contact measurement techniques for open-channel flow have been greatly improved by the advent of sensors and embedded system. The instruments based on radar, acoustic, optics and image offer superior efficiency and safety for hydrometry and hydraulic measurement. The article analyses the principle, performance and suitability of several non-contact flow instruments, and proposes application requirements of modem open channel flow measurement techniques. It concludes that the application of multi-sensor information fusion technology is the development direction of new technologies. It is insistent demand to research core technigues and equipment with independent intellectual property rights in our country for the current economic and social development and rivers related scientific research.
