Remote Monitoring And Control System On The Sluice Gate Along The Yellow River

The Yellow River is the main water source of northwest and north China, hich accounts for 2% of the total rivers' runoff of the whole nation, shoulders 12% population and water-supplying duty of 15% irrigating area of the whole nation, and shoulders long-distance water transfer to some areas out of the basin. With the rapid development of economic society in the basin and related areas, the supply and demand contradiction of water resources has been increasingly pricking up. In 1999, the State Council authorized Yellow River Conservancy Commission to arry out the integrated management of water resources and integrated dispatching of water quantity of the Yellow River. Yellow River Conservancy Commission took the following measures: ministrative measure, Lawful measure, Technical easure, Engineering measure and Economic measure,,Remote Monitoring and Control System on the Sluice Gate along the Yellow River is an important means to supervise the execution of injunction for superintending current and to insure the Yellow River's free from standstill. Also, it is the important parts of and main technical means of construction for "Digital Yellow River" and construction for the Yellow River's Current Superintending Management System.In this paper, the concept of system integration is introduced firstly in order to promote the Monitoring and Control System on the sluice Gates in view of system; and then some advanced technologies used in the Monitoring and Control System on the sluice Gates are discussed, included distributed control system (DCS), fieldbus and Programming Logic Controller (PLC). As required by The Technical Regulations of the Monitoring and Control System on the Sluice Gates along the Yellow River, the principles of the whole system's credibility, real time and safety must be followed and the particular design and actualizing principles should be provided. On the basis of these above all, according to the variant requirements of sluice gates, three design schemes are provided and comparatively analyzed which are the single point to single stage, the single point to multiple stages and multiple points to multiple stages.
