Design of supervisory control and data acquisition system based on GIS technology

Abstract

To solve the problems of distributed control and lack of geographic information technical assistance in the process of integrated automation development for Supervisory Control and Data Acquisition(SCADA) systems,system integration technology was applied to achieve comprehensive design of the Geographic Information System(GIS) and SCADA system in terms of data,interface and function.The comprehensive monitoring system was developed based on the multilayer structure of C/S.ActiveX technology was used in the developmental process to complete the system integration,and the SCADA system was used as the basic means of monitoring and control,while the GIS was used to provide the necessary geographic information analysis and processing functions.With the establishment of integrated database,the seamless connection of GIS with SCADA and sharing were realized,and the data consistency and real-time performance of the integrated system were ensured.The communication between the devices and remote clients helped the system to realize on-site video monitoring.Safety measures were also integrated in the system.The system is now successfully applied in actual working environment,and all functions are verified with stable operation and high scalability.
