State authorities are going real-time, too. Whether you count cars on the highway, auto-measure maritime traffic in large harbors, or consolidate emission data in central data stores, the notorious small budget requires open and flexible technology, which can still grow to enormous scale.
Central Repository
All data of system:Nozom, including data from the field, but also internal system monitoring, statistics and logs, is stored in the central repository, which serves also as the unique configuration interface of the entire system. To be completely independent from the individual data source and flexible to reflect any given structures, a schema-free open database is used. system:Nozom consolidates all data into one central repository, that can be easily accessed by any modern corporate IT.To support very large systems the database supports clustering and redundancy to increase the storage capability to any level required.
Core & Computing Scalability
system:Nozom´s Core Service controls the underlying architecture of Connector instances. It distributes configurational changes, processes incoming data and creates reflective images of the data in the Repository, such as the Process Image, Alarms and Events or Data History. To allow for very large systems or redundancy, system:Nozom supports multiple, parallel Cores.
Network Security
system:Nozom respects the mandatory need for a distributed and secure network architecture, by fully supporting firewall protection on each network level involved, be it on the individual site, or on the enterprise network layer. The communication of system:Nozom‘s main components relies on true single TCP port connections, thus shielding away remote integration hassles, such as remote DCOM configuration.
Connector & Endpoint System Integration Scalability
The system:Nozom Connector is the application exchanging data with multiple systems and interfaces, typically residing on a remote location, but this is not a requirement. If the on-site infrastructure is lean and OPC UA data sources are available, system:Nozom can connect thousands of them from a central data center.
Interface Standards
Historically, OPC was mostly used in classical industrial automation, and the footprint and cost of DCOM-based OPC servers was high. Now, with OPC Unified Architecture a simple nano-server – e.g. for car traffic measurement – can run on any Operating System, even on an embedded chip. This opens up a large new field of applications, and we see state authorities moving forward adapting the OPC standard.
Support for Various Information Sources
Especially with the new technical opportunities which come with OPC Unified Architecture, state authorities have new options to create a nationwide, standardized real-time measurement infrastructure for the various requirements mentioned above. system:Nozom supports the migration from older technologies such as file-based measurement transmission in parallel.
