How to control invasive traffic surveillance system?
The system software platform is a program system located between the operating system and application software system, using a variety of techniques to provide SCADA based software services, including real-time database, general HMI, communication and data flow management, input and output subsystem, command system, alarm / event management, system log, history database, diagnosis, school redundancy, and application development tools etc.. The large-scale monitoring system is an open architecture software system, which supports multi platform mode, each layer has the design logic correlation and independence, scalability, openness and sustainable expansion of the system. A product that accommodates different functions and platforms, and emphasizes reuse of application design, operational experience and engineering experience. Object oriented real-time database and HMI are provided by means of modular structure and component reuse. The key solutions include open architecture, design technology, component reuse technology, computer network technology, multimedia technology, communication technology, compilation technology, reliability assurance technology, etc..
Application requirement is the foundation of building large-scale monitoring system. The comprehensive monitoring system of urban rail transit is based on the specialized subsystems such as PSCADA and BAS, and integrates several professional information in accordance with the urban rail transit operation requirements, so as to realize the comprehensive monitoring function. The application needs are directly reflected in the monitoring system of the data display layer, namely all levels of operator workstation HMI, through HMI, the monitoring system provides rich functions to meet the needs of users, support operations personnel especially in emergency situations of daily monitoring, and through a number of projects in the accumulation and operation mode of the in-depth study, explore and form decision support system, provide the application functions required for the operation of the.
Urban rail transit integrated monitoring system is a large-scale SCADSA monitoring system. It is based on the system of backbone network, through professional interface device, multi specialty, multi system data acquisition, information integration and information sharing in the SCADA system software platform, providing advanced technological means for city rail transportation scientific and efficient operation organization and management. The MACS-SCADA system is the system of Hollysys company dedicated to the application of large-scale monitoring, comprehensive monitoring and control of city rail transit city track traffic specific application requirements based on monitoring functions such as PSCADA, BAS, support FAS, ATS, ACS, AFC, PIS, PSD and other professional system.
