Technical Features/Advantages
This system has uniform collection, processing, storage and display of multi-specialty information, and can provide operational monitoring, operation and control, monitoring management, and system maintenance of related plants and stations.
It supports the integrated graphic-mode library technique and provides one-key automatic imaging of monitoring screen, which can effectively eliminate omissions caused by manual drawing and significantly improve the imaging efficiency of monitoring screen.
It provides communication protocol management capable of dynamic expansion, which can meet the requirement for communication access in different periods and different scenarios.
It has great compatibility: supports multiple self-dependent & controllable/ non-self-dependent & controllable underlying systems, achieves service-based access to underlying resources, standard platform services, and modular upper-layer applications, and improves the maintenance, expansion and compatibility of engineering applications.
It supports the secure sandbox isolation technique, realizes isolation between applications and applications and secure isolation between applications and platforms, and effectively strengthens the security of power monitoring system.
It supports the hierarchical and optimal dispatching based on underlying resources, and this can effectively guarantee rapid response of real-time monitoring services.
It supports flexible load balancing and centralized deploying technique, which can improve the service processing capability of system and ensure high reliability of service.
It has complete self-diagnosis and self-recovery ability, failure or exit of a single module will not affect the main functions of system, and any human or machine operational mistake will not cause function loss or collapse of system.
It has powerful script calculation function, which can realize custom configuration of various calculation signal expressions and complex control blocking logic.
Supported by complete debugging and acceptance tools, the system has various debugging and auxiliary tools, such as the tools for communication simulation, automatic point-to-point, and network message monitoring and analysis, which can significantly improve the efficiency of debugging and acceptance.
It supports flexible expansion, which has continuous expansion and access ability of plants and stations.
It supports the database tamper-proof and one-key safe recovery technique, which can ensure the storage security of operation and monitoring data.
It achieves self-dependent and controllable core software and hardware, and the technology is secure, advanced and reliable.
