SCADA Data Processing Module Development: Design and Implementation Overview

This document outlines the progress and design details of the SCADA Data Processing Module. It includes a review of completed work, database design specifics, and a detailed design featuring Data Flow Diagrams (DFDs). The work division among team members is specified, highlighting tasks related to database schema creation, web interface development, and digital to engineering value conversion. Future work focuses on error checking mechanisms, including zero suppression and reasonability checks. A summary of the finalized database design is also provided.

  2. Agenda • Review • Work done till now • Database Design • Detailed Design ( DFD’s) • Work Division • Future Work

  3. Review • Digital to Engineering Conversion • Linear • Non-Linear • Piecewise Linear • Zero Suppression • Reasonability Check • Limit Check

  4. Work Done • Finalized Database Design • Created Database and populated with sample tuples • Developed web interface for providing basic operations of the database like • Insert • Update • Delete

  5. Database Design • Transducer Characteristics • Digital and corresponding Engineering values • Limit Specifications for • Zero Suppression • Reasonability checks • Limit checks

  6. Database Schema Digital To Engineering Zero suppression Reasonability check Limit check Characteristic function

  7. Database Schema(contd..) Transducer characteristics Linear Piecewise linear Continuous

  8. Initial System Design Characteristic function Converter Zero Suppression Category Engineering Value Digital Value Input Litid+DigVal Reasonability Check Database No Display Error Yes No Limit Check Display Output Yes

  9. Detailed Design – DFDs – II 5. function Characteristic function Converter User 0. Submit event 2. LitId 6. EngVal 1. Input LitId+Digval Check 3. LitId 8. checked_value 4. function Database 7. Limits Converter DFD

  10. AddNew DFD - II AddNew (Null checks) 0. LitId Timestamp DigVal User 1. insert(LitId, Timestamp, DigVal)

  11. Delete DFD – II Delete 0. LitId Timestamp User 1. delete(LitId, Timestamp)

  12. Modify DFD – II Modify (Null checks) 0. LitId Timestamp Others.. User 1. Update(LitId, Timestamp, others..)

  13. Work Division • Database schema design (All team members) • Detailed design (Kiran and Ajay reddy) • Web interface design and Query generation. (Revanth, Siva Suman and Ravi Teja)

  14. Future Work • Digital to Engineering Conversion • Error checking mechanisms for • Zero Suppression • Reasonability checks • Limit checks
