GBI Data and Sorting Systems, Inc.

Redesigned and rewrote legacy software to control large tilt-tray sorting machines - the GBI Sorter Interface application.  This Windows Forms application includes:

·   XML configuration file parsing to set application startup configurations such as database connection strings, socket server/client IP addresses, sorter machine settings, file paths and other data.

·   Tabbed user interface written by hand.  Did not use the VS Designer due to its inefficiencies and lack of modification tracking.

·   Proprietary classes for SQL Database manipulations, real-time serial port communications, Client/Server socket messaging, IBM WebsphereMQ messaging, Application Configurations, Folder watchers and file processors.

·   Sortation Waves section accesses multiple database tables to generate a list of sortation waves and provide wave control such as sort method, activate, suspend, force close and wave data archival.

·   Wave Progress section displays auto-updating graphical sortation progress charts

·   Load Station section allows for manual product load controls such as item count entries and barcode scanning of individual products, pallets and totes.

·   Machine Status section displays sorter component statuses such as chain state, drop location status and level, dropped item counts and details, node, loader and printer statuses, graphical interface of drop location panels with real-time serial control.

·   Reports section provides detailed printable sortation reports by wave or date range using the .NET GDI imaging system.

·   WMSI section provides A WMS (Warehouse Management System) interface to import sortation wave and product data and export sortation results.  Import/export methods included flat-file and XML file parsing using a continuous folder watcher, client/server IP socket data exchange, shared database access and web service data exchange.

·   Diagnostic section provides real-time monitors for serial port communications with sorter node boards, pick-to-light drop panels, custom 40-key keyboards, specialized label printers and RF barcode scanners.  Also provides monitors for both client and server socket messaging data.

·   Message Log section provides real-time event data logging and display with status and date filters.

Designed and developed full industrial conveyor system layout and control software, the GBI Conveyor Interface application.  This Windows Forms application includes:

·   Tabbed user interface with individual ribbon controls per tab.

·   Conveyor Builder section provides a graphical CAD system to design and draw scale models of complex conveyor systems including seven conveyor bed types and over 20 sensor and device controls.  Also includes transport bed, tote control and sensor device editor dialogs as well as a comprehensive conveyor rule editor with real-time execution to control all conveyor bed and device decisions including precise timing of events.

·   System Monitor section allows run/pause/stop control of individual conveyor sections.  Also shows real-time transport bed status, device status and alarm conditions.

·   Reports section provides detailed printable sortation reports by wave or date range using the .NET GDI imaging system.

·   Diagnostics section provides monitors for serial port communications with sorter node boards, pick-to-light drop panels, custom 40-key keyboards, specialized label printers and RF barcode scanners.  Also provides monitors for both client and server socket messaging data.  Also provides an auto-updating chart of all conveyor devices showing sections, conditions, alerts and  alarm statuses.

·   Message Log section provides real-time event data logging with status and date filters.

Also documented this application with a detailed User's Manual in MS-Word.

Designed and developed a graphics Motor Parameter Plotter application that allowed for the serial connection of DC motor driver boards to the PC to provide:

·   The ability to manually send commands to motor driver board.

·   Read and compute values for motor position, velocity, acceleration and torque.

·   Plot motor data vs. time on a multi-color cartesian graph with stretch, zoom and auto-scale features.

·   Display popup table views of all serial data sent by the motor driver board.

·   Import and export of motor data with Microsoft Excel spreadsheets.

These applications use multi-threaded OOAD and OOP with C#/WinForms using the .NET 3.5 Framework, Visual Studio 2008 and SQL Server 2005/2008.

In addition to writing these applications, acted as remote desktop technical support for customer deployments and installations.
