The Design And Implementation Of The Integrated Supervisory Control System Based On Wonderwareias

With the continuous development of urban mass transit, urban mass transit monitoring system has also undergone great changes for the more and more widely used scope and more and more highly degree of automation. However, there are many of the monitoring system which are just for one specific system or a particular type of equipment management and control at present, and there is no communication informations between lines,which often forms the separate information"islands",and can not locate analyse and process the system run on information especially of the electrical devices fault situation ,the linkage effects of the system is not satisfied,and the transfer between lines is difficult.ISCS standes for Integrated Supervisory Control System, is a proposed solutions for the requestion of shared equipment and information and unified management of Urban mass transit. ISCS combines electrical related subsystems of every station through the control center, achieve the full share by various integrated and Interconnect sub-systems , enhance management decision-making and information serving ablility.For the complexity and diversity of the monitored object, we proceed from the point of data-flow and control-flow view, put forward two management levels and three control levels, and design the three-levels architecture, namely, integrated decision-making layer, station decision-making layer and field control layer.Carry out a in-depth study of system components such as BAS,SCADA,FAS and so on, make a exhaustive analysis of system demands includes: all monitored points,devices status,interface design,linkage effects between sub-systems and response time, give out the user access permissions control strategy, carry out a detailed analysis and design of the database and the security of system on this. On WonderWareIAS companys'platform ,we choose the InSQL Server database structure, make it out to meet the owners'real requirements of information sharing,decision support,response timely and so on to get operational efficiency, rapid decision-making, public service, networking information. ISCS plays a greater role in the whole and try to makes urban mass transit system achieve the best running.
