Introduction
Since the 12th Five-Year Plan of China, intelligent water resources have become the development trend of water resources in the new era. Water informatization is promoting the transformation from traditional water resources to modern water resources [1][2][3]. Making full use of the new generation of information technology to ensure the benefits of water resources and hydropower projects is the development trend of the water resources and hydropower industry. At present, intelligent water resources construction has been carried out in Jiangsu, Fujian, Zhejiang and other places. New technologies such as big data, cloud computing and Internet of things have been fully utilized to excavate water resources and comprehensively improve the efficiency and efficiency of water resources management [4][5].
Qinhuai River Water Conservancy Project is one of the main control projects in Qinhuai River Basin. The Qinhuai River Pumping Station undertakes the functions of irrigation, flood control, drainage and pollution scouring. The station is equipped with 1700ZWSQ10-2.5 bidirectional horizontal axial flow pumps and total installed capacity is about 3150kW. It benefits the flood control and drainage and water quality improvement [6]. However, due to the lack of planning and coordination, the efficiency of system maintenance is low, the existing data integration is poor, and the data are not fully utilized, leading a certain extent limit on the management ability and information of Qinhuai New River. This paper introduces the design idea and main project of the information management system for the intelligent pumping station based on the actual situation of Qinhuai River, and provides a reference for improving the information level of Qinhuai River

Overview of the Information Management System
Qinhuai River Intelligent Pumping Station Information Management System is located between the computer monitoring system of the pumping station and the management information system of the superior management department. It is the working platform of the pumping station. For one thing, it 2 receives all kinds of real-time running data of the computer monitoring system before analyzing, processing and reporting the relevant statistical results to the superiors. For another thing, it receives instructions and data from the superior management and dispatching department. At the same time, this system also has daily management functions of pumping stations, such as on-duty management, dispatching management, equipment account management and so on. Fig. 1 indicates a hierarchical diagram of the information system of the intelligent pumping station which is divided into four layers. The lowest level is the computer monitoring system of the pumping station, and the top two levels are the management information system of the superior operation dispatching management system and the superior engineering management department. Pumping station information management system is an important link between computer monitoring system and superior dispatching management system of pumping station. It is the basis of standardizing the operation management process, improving the operation level and ensuring the safe operation and maintenance of pumping station. Fig. 1 Schematic diagram of intelligent pumping station information system Before the operating of information management system of Qinhuai River Intelligent Pumping Station, the system of pumping station only had some functions such as data storage, statistics and report forms by a single function monitoring computer. There was no security measurement to realize data sharing and remote browsing of operation status. The single-machine version of daily affairs management software can not realize the network. The research and application of pumping station information management system is seriously lagging behind with the development of modern management. Information management system of intelligent pumping station adopts advanced system architecture and cross-platform system integration development tools. By integrating the operation monitoring, operation process management and transaction management of the pumping station on one platform, it not only facilitates the daily work of the operators, standardizes the work flow, but also records and manages various data in the operation, maintenance and management of the pumping station. The information management system is helpful for further event tracking, historical data analysis, and joint operation optimization of pumping stations.
The system provides a network operation monitoring and management platform. Operating managers can complete the management of pumping stations through the network. Relevant personnel can browse the operation status of pumping stations or inquire information through the Internet or mobile phones. The Rich Internet Applications (RIA) architecture based on Silverlight is adopted to realize the integration of real-time monitoring and management system for pumping station operation.
The architecture is open and easy to expand or reconstruct. The data gateway based on OPC technology and the network gate based on double ferry mechanism are both used to realize the highspeed and safe transmission of data between the monitoring system and the management system of the pumping station. It stores a variety of key operation, statistics and management data, which provides a basis for operation optimization, benefit analysis and fault tracking of pumping stations in the later stage. The lowest level of information management system is the computer monitoring system of pumping station. JX-300X DCS system is used to realize the functions of data acquisition and control of main unit, auxiliary equipment, substation, gate and so on. The middle layer is the information management system of pumping station. It obtains all kinds of real-time data of pumping station operation through OPC server, and provides real-time data to the higher management department. Qinhuai River Management Office or higher dispatching management department can browse the real-time operation conditions of pumping stations remotely through LAN or Internet.

3.2Software Architecture
The bottom part of the information management system is the software module of pumping station operation data acquisition, which realizes the data acquisition and processing of the main unit, auxiliary equipment, substation, gate and so on. These software modules are at the bottom of the information management system of large pumping station, in which the data gateway service is provided. The end software realizes the centralized processing and data forwarding of the collected data. In order to realize the security isolation between the bottom and the top of the system and avoid the security threat to the bottom software and hardware system, the technology of double ferry security isolation and information exchange is adopted. The client software of the data gateway in the upper layer can use the double ferry information exchange method to obtain various data of the computer monitoring system of the pump station in the lower layer, thus realizing the data opening and sharing of the management network, and facilitating further access to the corresponding tables of the database in the management network.
