【摘要】 近年来,橡胶坝以它投资少、工期短、见效快以及管理方便、适应性强等特点,越来越受到人们的青睐。沂河桃园橡胶坝工程作为山东省临沂市滨河综合整治工程中的重点工程,担负着保障城市工业和生活供水、回灌地下水、发展水上交通旅游及建设生态城市等多项功能。整个工程由充水式橡胶坝和船闸两部分组成,其中船闸东西长25m,橡胶坝长783.2m,枢纽总长988.2m。为了更好地确保橡胶坝安全运行和可靠运行,使其发挥应有效益和功能,我们设计和开发了桃园橡胶坝监控系统。桃园橡胶坝监控系统是确保沂河水量科学调度和监督管理的有效措施。系统综合采用了当今先进的计算机应用技术、PLC技术、网络技术、自动控制技术、数字图像编解码技术、多传感器信息融合技术、检测技术、有线/无线通讯技术、多媒体技术等,实现了信息图像控制一体化的综合监控系统,确保了沂河安全调度管理的监控自动化。本课题主要研究了以下内容并加以开发实现:1.橡胶坝充排水智能控制,通过实时监测坝袋内压、上下游水位、葛沟水位和流量以及坝袋高度等,利用软起动器,实现橡胶坝的充排水自动控制;2.船舶上行过闸和下行过闸的自动控制;根据上下游及闸室水位、闸门开度、以及限位等传感器,配合交通信号灯,实现船闸的自动控制;3.实现现场和上位带权限闸门和坝袋的调度与控制,并实时返回各闸门和水泵的状态信息;4.大坝安全自动监测,通过对渗流自动测量,利用分位图法获得一致性传感器组,在此基础上采用了多传感器信息融合理论对数据进行融合处理;5.图像传输及编解码技术,实现了图像有线和无线实时快速传输,通过有效的编解码技术,提高了图像质量,并实现了摄像机的远程控制,包括云台,镜头控制;6.研究开发了适用于橡胶坝监控调度的操作平台,采用标准的图形界面和操作模式,模拟动画,再现了橡胶坝运行状况和周边坏境,操作简单、安全、可靠。本文对橡胶坝充排水控制,无线接入技术,视频传输方式,上位监控以及多传感器信息融合技术等问题作了较为深入的研究,成功实现了橡胶坝的实时数据监测、实时图像监视以及橡胶坝实时控制。该系统自2007年9月投入运行以来,运行状况良好,没有出现异常现象。更多还原

【Abstract】 In recent years, the rubber dam is favoured by more and more people for its small investment, short period of construction, quick effect, easy management, adaptability, and other characteristics. Taoyuan rubber dam in Yihe River as a Riverbank comprehensive harnessing of the key projects in Linyi City in Shandong Province, it charges with many functions, such as the protection of industrial and urban living water supply, groundwater recharge, the development of tourism and water transport, building a eco-city, and so on .The entire project includes both the water-filling rubber dam and the sluice. The whole length of the hub is 988.2m, of which the width of the sluice is 25m and the rubber dam is 783.2m long. In order to insure the safe and reliable operation of the rubber dam, and to make it work as the desired efficiency and function, we have designed and developed the monitoring system of Taoyuan rubber dam.The dam monitoring system of Taoyuan rubber is an effective way of strengthening the water scheduling and supervision. This system adoptes the contemporary advanced technologies, such as modern computer science, PLC technology, network technology, automatic control technology, Digital image coding/uncoding technology, Multi-senor data fusion technology, Intelligent detection technology, wired/wireless communication technology, multimedia technology and so on, realizing the integrated monitoring system of the information, image and control, which has guaranteed the safe management and monitoring automation of Yihe River.In this paper, we research the following contents and put them into effect:1.Intelligent control of water filling and drainage.Through the real-time monitoring the dam bag pressure, water level of upstream and downstream, the water level and flow in Gegou, and the dam height and so on, we use the soft-starter to realize filling and drainage control of the rubber dam.2.The automatic control of Ships’ up-going and down-going According to the automatic measurement about water level of upstream and downstream and the sluice chamber, and the gate opening, limit sensors, with the help of traffic lights, we have realized the automatic control of the sluice.3. Realizing the scheduling and control of the authority sluice and bag both the locale and HMI, with returning the real-time various conditions information of the gates and pumps.4.Automatic monitoring of the dam safety.Through the automatic measurement of the seepage, use the plot-bit map method to achieve consistency sensor group, based on this information use the theory of a multi-sensor information fusion to merge the information.5. Image transmission and coding/uncoding technology, which realizes the wired and wireless real-time rapid transmission of the images.Through effective coding and uncoding technology, it improves the image quality, and realizes the remote control of cameras, including Pan & Tilt and the camera lens control.6. We has researched and developed the operation platform which is suitable for the scheduling and monitoring of Yihe River, adopting a standard graphical interface and operating modes, simulation animation, describing the operation of the rubber dam and the surrounding environment. The operation is simple, safe and reliable.There is a deep study to water filling and drainage control, wireless access technology, video transmission, HMI monitoring and multi-sensor data fusion technology and other issues in this thesis, succeeding in realizing the real-time data monitoring and image monitoring and real-time control. Since put into operation in September 2007, the system has been running in good condition without fault.更多还原
