H2 Data Acquisition
H2 is a general data acquisition system that, in addition to Scanmatic’s own stations, also supports the collection from other data loggers. A wide range of protocols, both standardized and proprietary, are supported. Data is stored in an open SQL database and can be displayed in a web-based presentation module or forwarded to parent systems (eg operating centers) on standard protocols or file formats.
H2 runs as a service on all modern Windows platforms and has web-based management and presentation tools. For easy access to collected data from third-party tools, there is a well-documented RestAPI as well as a SignalR interface. For access control to stations and data, user groups and station groups are used. A user group can have access to only selected stations and it is also possible to restrict access to individual measurements to selected user groups. H2 has its own module for calculating new measurement values based on collected data. This can be done, for example. be conversion between different units or calculation of water flow from water level. Notification of events based on e.g. Limit values can be done via mail and SMS
