Relevant projects: 1) RMQS Application: eSolar developed the Reflector Module Assembly System (RMAS) which is an assembly line for creating reflector modules (RMs) The RMAS had many parts including several robots, conveyor belts, safety equipment and more. One of the key parts of the RMAS is the Reflector Module Quality System (RMQS), which main function is to measure both RM frames and built RMs and ensure quality by identifying bad frames or bad RMs during construction. The RMQS application has 3 modes: Configuration, Calibration and Operation. In Operation mode the RMQS application records data from an RM Frame Inspection Station, communicates to cameras mounted in the RMQS target screen, communicates to the PLC running the RMAS, commits all recorded data to a database, commits computed values for slow computation to the database. This application also provides a user interface allowing the RMAS operator to see the data and spot trends in the quality. The RMAS is run by an Allen-Bradley PLC as its main control system and the RMQS Application interfaces with that PLC and captures the data the PLC has in memory. 2) RMQS Diagnostic Tool: This application allows analysis of data previously collected from the RMQS Application. The RMQS Diagnostic tool connects to a remote database and presents the user with a view of that data collected by the RMAS. The RMQS Diagnostic tool allows for viewing of the RM frame measurements, the RefMet calculations, and the slope maps. 3) RMQS Data Replication Tool: This application allows for production data to be replicated back to eSolar's headquarters and consumed by tools like the RMQS Diagnostic Tool.
