摘要
基于相似理论设计的水利河工模型试验,需要模拟天然的水沙和边界条件,针对三峡工程坝区泥沙模型试验研究的内容,控制系统应用了先进的电子技术、传感技术和计算机硬、软件技术,自动控制模型试验双线船闸充泄水方式和流量,并对模型试验的流速、水位、含沙量、波高等数据实施多点同步采集与处理.控制系统功能较完善,软件界面美观新颖,操作简单方便,具有很强的可视性和交互性,已先后成功地应用于三峡工程坝区泥沙模型试验和多项国家重点科技攻关项目,具有推广应用价值.
The hydraulic model test designed based on theory of similarity needs to simulate natural water,sand and boundary conditions.In connection with the contents of sedimentation model test research in Three Gorges Project(at dam site),the control system applies the advanced electronic technology,sensing technology,computer hardware and sofware technology,controls automatically the water filling and sluicing of model test of dual gates,the way of water filling and sluicing and the rate of flow,and also carries out synchronic data acquisition and processing of the velocity,water level,sediment concentration and wave height.The control system has been already applied to sedimentation model test of Three Gorges Project(at dam site)and many national key projects successfully.
