Research And Design Of GIS And Scada Integration Technology In Highway Monitoring System

Data acquisition and supervisory control system can monitor and control the operation of the field device, in order to achieve the functions of data acquisition, device control, parameter adjustment and a variety of signal alarm, has been widely applied in various fields. To solve the problems of distributed control and lack of geographic information technical assistance in the process of integrated automation development for SCADA systems, utilizing component integration technology to achieve the comprehensive design of Geographic Information System and SCADA system, and the design results has been applied to the highway monitoring and operation management. In this process, the SCADA system as the basic means of data monitoring, while the GIS for the system to provide the necessary geographic information support. The combination of GIS and SCADA system can solve the problem that traditional monitoring system does not have the the ability to dealing with space data related to geography graphics. The main contents of this paper are summarized as follows:1) This paper firstly analyzes the ways and means of system integration based on studying the GIS and SCADA systems, and summarizes the current commonly system integration mode used in the process of actual development. Focus on the establishment of a versatile information monitoring system.2) According to the analysis of system integration, focusing on the use of component-based integration technology in the system. GIS functions as the control objects embedded in the highway data acquisition and monitoring system, and the GIS module is divided into several controls, each control to complete the corresponding function. Finally, the actual application system is formed by using a visual programming environment for the integrated development.3) Provided a clear design objective and task, and discusses the management mode and hardware components of the monitoring system. The monitoring system has been developed based on the multilayer structure of C/S to realize data acquisition and remote control. With the establishment of integrated database, the seamless connection of systems and data sharing are realized, and the data consistency and real-time performance of the integrated system are ensured.4) Departure from the perspective of software functionality design, according to the division of each application module, this paper analyzes the various functions of the system in detail, designs the related flow processes and develops the software in order to implement the integration of system in terms of data, interface and function. The system is now successfully applied in actual working environment, and all functions are verified with stable operation and high scalability.
