SCADA_SNUS

Project for "Software of supervisory management systems" university course.

The project is a general SCADA management system, composed of four main components:

  • RTU client - C# console app simulating field sensors, sends new tag values every 1000ms to the core
  • SCADA core (back) - the heart of the backend, a multi-threaded ASP.NET application that runs the scan simulation in the infinite while loop + HTTP/ws endpoints
  • front - simple and efficient Angular UI
  • SQLite database - for storage and backup

The frontend is further broken into three semantic clients:

  • Trending - displays real-time updates of the tag values and alarm notifications, both arriving from the core through web-socket connections
  • Database Manager - interface for CRUD operations on input and output tags
  • Report Manager - displays detailed reports on chosen criteria

The app is not heavy on authorization and authentication (not the focus of the project), still, there are two user roles:

  • Admin - has access to all UI components and functionalities, as well as the CRUD operations on all entities
  • User - can only monitor tags through the Trending app upon login

All above makes for a well-crafted simulation of general principles behind SCADA system management.

Terminology

  • Tag - represents a single physical quantity (analog tags - temperature, humidity...) or state (digital tags - off/on), and can be used to read the value (input tags) or to set it (output tags)
  • Scan and scan time - determines how frequent is the reading of the new values of the input tags (scan time) and if the values in the frontend/db should be updated at all (scan boolean)
  • Driver - specifies whether the new input tag values are provided by the RTU_Client simulation (Real-time driver) or by applying a function to the current timestamp (Simulation driver)
  • Alarm - triggers when the tag value is greater/lower than the critical value, the priority of the alarm maps on the intensity of the notification in the Trending app

Technology stack

Running the project

To run the project:

  1. clone git repo
  2. run RTU_Client solution to start the simulation of the sensors
  3. run snus_back solution to start the backend core
  4. run front Angular app to start the frontend

*Registration of new users is not supported through the UI, you can add them directly through a database management software of your choice - after that you can log in and enjoy the app :)
