|
摘要
已有的长江河口段模型控制系统,上游采用量水堰+扭曲水道进行流量控制,下游采用潮水箱和尾门进行潮位控制,通过485有线通讯方式采集数据。针对原有控制系统老化、量水堰控制流量时试验准备时间长、扭曲水道占用试验场地、485有线通讯设备布置较为困难的特点,考虑到大型潮汐河流模型河口边界条件复杂、长河段、受径潮流的共同作用,对模型布置和自动化控制系统进行了研究。将网络技术、无线通讯技术和模块化设计成功应用于长江河口段模型的控制中,形成由供水、径流流量控制、下游生潮控制等模块组成的标准化、模块化、无线化、智能化和远程化的控制系统。分析结果表明,标准化的新控制系统重复性好,控制精度高于现有规范要求;模块化设计的系统工作稳定、维修方便;智能化和远程化的控制系统操作简便;无线通讯的试验设备布置方便。新的径流控制系统占用模型试验场地少、试验准备时间短,模型试验效率大大提高。该系统具有很好的推广使用价值。
The existing Yangtze River estuary model control system upstream of the amount of water weir plus twisted channel for flow control,the downstream use of tidal tank and tailgate for tide control,data collection using485 wired communication. In this paper,the design of the control system for the aging of the original control system is very difficult to control the flow time,and the design of the 485 cable communication equipment is more difficult.Considering the complicated large tidal river model,the complicated boundary condition of the river,and combined action of the runoff and tidal current on the tidal river mouth,an in-depth study of the model layout and the automatic control system is carried out. The network technology,wireless communication technology and the modular design is successfully applied to the control of the Yangtze River estuary model,modules such as water supply,runoff control,and downstream tide control,and a standardized,modular,wireless,intelligent and remote control system is composed of. Experimental results show that the new control system has good repeatability and high control precision,which is higher than the existing specifications. The application results show that the system design of the modular design is convenient and the test equipment of the wireless communication is convenient. The new runoff control system occupies the model the analysis results show that the standardized new control system has good repeatability,high control precision and higher than the existing specification. The control system of modular design is stable and convenient for maintenance. The intelligent and remote control system is easy to operate. The test equipment equipped with wireless communication is convenient,the new runoff control system takes up less model test sites,the test preparation time is short,and the model test efficiency is greatly improved. The system has a very good use value.
