[Abstract]:The automatic hydrological measuring and forecasting system (hereinafter referred to as "the system") is a real-time collection, processing and transmission of important hydrological parameters, such as hydrology, flood information, and engineering conditions, which are comprehensively applied in remote sensing, communication, computer, network and other advanced science and technology. To provide automatic forecasting system for flood control of water conservancy and hydropower projects as well as benefit and optimization operation. The construction of an automatic water regime monitoring and forecasting system in the Dongyi River Basin is one of the important means to ensure the safety of engineering construction, to allocate water resources scientifically and reasonably, to solve the contradiction between power generation and flood control, and to improve the economic benefits of the project. It is one of the basic goals of realizing the modern management of cascade hydropower stations and the need to realize the joint operation and optimal operation of cascade reservoirs and to maximize the comprehensive benefits of hydropower projects in river basins. This paper is to meet the needs of hydropower development and construction in Dongyi River Basin, combined with the characteristics of Dongyi River Basin, on the basis of the investigation of the station of automatic water regime monitoring and forecasting system and the testing of communication channel in Dongyi River Basin. The overall structure and function of the automatic water regime monitoring and reporting system in the Dongyi River basin are designed, the telemetry station network is analyzed and arranged, the communication mode and system working system are compared and selected, and the data transmission communication network is made. At the same time, according to the river basin situation and the forecast requirement of cascade power station, the forecast scheme, central station integration, telemetry equipment integration and computer network system, database system, data receiving and processing system, are designed. Business application system, information publishing system put forward the design plan. The main content is: 1. The general situation of Dongyi River Basin, climatic characteristics, runoff, rainfall and flood characteristics, and the general situation of the project are investigated and analyzed, and the basic data are collected and sorted for the design of the automatic water regime monitoring and forecasting system. According to the basis and design principle of the design of the automatic water regime measuring and forecasting system in Dongyi River Basin, the main functional requirements of the system are summarized and analyzed, the overall structure and work flow of the automatic measuring and forecasting system are designed, and each subsystem and the overall implementation scheme of the system are determined. The range of system observation and reporting is demonstrated, and on the basis of the demonstration, the telemetry station is arranged on the basis of the principle of website layout. The selection of telemetry equipment and the main technical specifications are analyzed and determined, and the equipment integration. 4. 4. This paper discusses the layout principle of flood regime forecasting scheme, analyzes the flood propagation time, designs flood forecasting scheme for dam (gate) sites of all levels of hydropower stations in the whole basin, and puts forward a suitable model .5. The design of hydrological collection subsystem and information transmission subsystem of automatic hydrological regime monitoring and forecasting system in Dongyi River basin is proposed and the function and main technical requirements of the subsystem are determined. On the basis of analyzing and comparing the data transmission methods commonly used in the field of automatic hydrological monitoring and forecasting system at present and synthesizing the topographic characteristics and economic development of local watersheds, this paper puts forward the concrete plan of collecting. 6. Based on the selection of communication mode for the system. For the central station computer network system, database system, data receiving system, data processing system, business application system, information publishing system and so on, the design and function requirements are put forward.
