【摘要】：近年來，隨著水利水電技術(shù)和高分子合成材料工業(yè)的發(fā)展，適應(yīng)國家提出節(jié)約型社會、可持續(xù)發(fā)展等戰(zhàn)略的橡膠壩得到了越來越廣泛的應(yīng)用。并且，橡膠壩具有投資少、工期短、見效快、管理方便、適應(yīng)性強等特點。 撫寧洋河口橡膠壩工程完成之后，可以有效防洪擋潮，抬高內(nèi)陸淡水水位，徹底根治海水倒灌現(xiàn)象，有效的解決了上游15萬人的飲水及農(nóng)業(yè)生產(chǎn)等問題。整個工程由充水式橡膠壩以及船閘兩部分組成。監(jiān)控系統(tǒng)控制著整個系統(tǒng)的安全、平穩(wěn)運作，是整個系統(tǒng)最重要的部分之一。因此，開發(fā)出一套穩(wěn)定運行的橡膠壩監(jiān)控系統(tǒng)，對橡膠壩發(fā)揮其應(yīng)有的作用有著重要的意義。 首先，本文描述了國內(nèi)外橡膠壩及其控制技術(shù)的發(fā)展，，并結(jié)合橡膠壩特性及撫寧洋河口水域現(xiàn)狀，制定了監(jiān)控系統(tǒng)的控制策略與監(jiān)測方案。 其次，根據(jù)所指定的監(jiān)測方案與控制策略，搭建了控制系統(tǒng)的設(shè)計方案。本系統(tǒng)采用臺達(DELTA) PLC為主控制器，通過HMI進行人機界面交互操作，通過AIO/DIO擴展模塊對其它外圍設(shè)備進行控制；同時，對系統(tǒng)的硬件選型、控制流程等做了詳細(xì)說明，并對橡膠壩控制回路與主回路進行了電路設(shè)計。 最后，為實現(xiàn)壩袋高度自動控制，結(jié)合該控制策略，制定了查表法控制方案，通過現(xiàn)場調(diào)試及一段時間的試運行及數(shù)據(jù)監(jiān)測，證明該控制方案是簡單有效的。
[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.
