The SCADA system is a computer-based communication and control technology developed pipeline digitized . Its main function is : the automatic acquisition of the pipeline running process parameters , adjust the variables closely related to the safe operation of pipelines , station control room and control center to monitor the operation of field devices , provides a variety of data required by other enterprise application systems . In this thesis the context of the development and construction of the Changqing Oilfield Company first oil at the Jing the salty oil pipeline SCADA system to study the structure of the framework of the SCADA system , combined with Yang Shan Jing salty pipeline station control system of measurement and control needs , Dr Hill Station major equipment such as a pump unit , furnace , as well as on-site measurement and control instrumentation configuration and selection, to determine the field device control and protection program . Freelance 2000 software configuration programming , the station control system to establish a high degree of automation with remote monitoring capabilities . The project selection the ABB AC800F SCADA system , the system uses the integrated controller , open the latest technologies and standards , open communication , plug-and-play features . System software programming configuration work in Freelance 2000 Digitool completed , Freelance 2000 international standard IEC 1131-3 graphical programming language , with powerful software configuration . Thus, the short time the entire engineering design implementation , upgrade and maintenance of the system is relatively simple . Jing salty SCADA system speed data update , monitor screen refresh cycle is short, through various monitoring configuration screen in the center of the station control room and control in real time learned that the station 's production run situation , but also through the control of the monitor screen button remote station equipment , field parameters , process control . By the division of the operating authority , user management at different levels , in order to avoid malfunction caused by the accidents in production . System oil pump chain control station , water hammer control and out of the station pressure protection control , to ensure that production can be a safe , smooth , efficient operation .
