【摘要】：近年来，随着水利水电技术和高分子合成材料工业的发展，适应国家提出节约型社会、可持续发展等战略的橡胶坝得到了越来越广泛的应用。并且，橡胶坝具有投资少、工期短、见效快、管理方便、适应性强等特点。抚宁洋河口橡胶坝工程完成之后，可以有效防洪挡潮，抬高内陆淡水水位，彻底根治海水倒灌现象，有效的解决了上游15万人的饮水及农业生产等问题。整个工程由充水式橡胶坝以及船闸两部分组成。监控系统控制着整个系统的安全、平稳运作，是整个系统最重要的部分之一。因此，开发出一套稳定运行的橡胶坝监控系统，对橡胶坝发挥其应有的作用有着重要的意义。首先，本文描述了国内外橡胶坝及其控制技术的发展，，并结合橡胶坝特性及抚宁洋河口水域现状，制定了监控系统的控制策略与监测方案。其次，根据所指定的监测方案与控制策略，搭建了控制系统的设计方案。本系统采用台达(DELTA) PLC为主控制器，通过HMI进行人机界面交互操作，通过AIO/DIO扩展模块对其它外围设备进行控制；同时，对系统的硬件选型、控制流程等做了详细说明，并对橡胶坝控制回路与主回路进行了电路设计。最后，为实现坝袋高度自动控制，结合该控制策略，制定了查表法控制方案，通过现场调试及一段时间的试运行及数据监测，证明该控制方案是简单有效的。
[Abstract]:In recent years, with the development of water conservancy and hydropower technology and polymer synthetic material industry, rubber dam, which adapts to the strategy of economical society and sustainable development put forward by the state, has been more and more widely used. Moreover, rubber dam has the characteristics of low investment, short construction period, fast effect, convenient management and strong adaptability. After the completion of Funing Yanghekou rubber dam project, it can effectively prevent the tide, raise the inland fresh water level, completely cure the phenomenon of seawater recharge, and effectively solve the problems of drinking water and agricultural production of 150000 people in the upper reaches. The whole project is composed of water-filled rubber dam and shiplock. The monitoring system controls the security and smooth operation of the whole system, and is one of the most important parts of the whole system. Therefore, it is of great significance to develop a stable rubber dam monitoring system for rubber dam to play its due role. Firstly, this paper describes the development of rubber dam and its control technology at home and abroad, and formulates the control strategy and monitoring scheme of the monitoring system according to the characteristics of rubber dam and the present situation of Funing Yangkou Estuary. Secondly, according to the specified monitoring scheme and control strategy, the design scheme of the control system is built. In this system, Delta (DELTA) PLC is used as the main controller, the man-machine interface is operated by HMI, and other peripherals are controlled by AIO/DIO expansion module. At the same time, the hardware selection and control flow of the system are described in detail, and the rubber dam control loop and the main circuit are designed. Finally, in order to realize the automatic control of dam bag height, combined with the control strategy, the control scheme of look-up table method is worked out. through field debugging, trial operation and data monitoring for a period of time, it is proved that the control scheme is simple and effective.
