  3. Intro • For thousands of years mankind has sailed the oceans. • Only in the last century have we sailed beneath the surface. • Undersea Warfare is an area of great technological growth. • The US Navy operates a battery-powered large scale model submarine to study acoustic and hydrodynamic characteristics • Presently a Charging technician to monitor and manually control the charge process at the individual chargers (7 Propulsion and 1 Instrumentation) • The goal of this project is to develop a computer-controlled system to improve the efficiency of charging the batteries Team Zap Gap - LSV2 Charger Remote Control

  4. Project • Utilize the existing chargers without modifying them directly • Determine a reliable method of remotely articulating the functions of the chargers • Design a Graphical User Interface to control and display charger output Team Zap Gap - LSV2 Charger Remote Control

  5. Background LSV2, USS Cutthroat, is a self-propelled fully autonomous research submarine. • Bayview, ID on Lake Pend Oreille • Test platform for hydro acoustic and hydrodynamic analysis • 205 ton • 10’ diameter • 111’ length • Represents Virginia Class Submarines • Named in 1997 by Athol Elementary School for the indigenous Idaho fish. Team Zap Gap - LSV2 Charger Remote Control

  6. Solution • Interface via serial connection • RS-232 ( also configurable for RS-485 protocol) • Via a computer workstation • Control of Chargers via a Graphical User Interface (GUI) • Assembled using Windows Visual Studio 2008 • Communication ports are configurable to those available at the PC • MOXA CP-118EL • Gives eight additional COMM ports to give each charger a dedicated signal path. • Adds channel specific control for the user interface program Team Zap Gap - LSV2 Charger Remote Control

  7. System Block Diagram • Button Clicked in GUI • SCPI Command sent via RS-232 • Serial A to D interface changes output • Power level connected to Batteries is adjusted Monitor (GUI) Chargers PC • Propulsion: 1680, 2V, Valve Regulated Lead Acid Batteries (VRLA) • Instrumentation: 186 2V VRLA Batteries Serial COMM port (MOXA) Power to Battery Strings Cables (STP RS-232) Serial Interface (A2D) Team Zap Gap - LSV2 Charger Remote Control

  8. Connections COMM Port Expander (MOXA CP-118EL) A to D/ D to A board inside charger ICS (4861/2361) PC w/ PCIe 1x-16x DB9 cable connections to J4 10 pin header Team Zap Gap - LSV2 Charger Remote Control

  13. Hardware Test Bench Testing Onsite Test • Ensured the proper interaction of the A to D card and charger outputs • Generated flow diagrams for coding of the GUI • Verified the digital command fidelity in the EMI noise of the U of I power lab • Test performed on charging units at the Bayview Naval Base • Commands used during a charging profile were tested successfully • Returned data (voltage and current output level) was incorrect • Calibration procedure of the analog to digital branch of the ICS electronics board should fix this error Team Zap Gap - LSV2 Charger Remote Control

  14. Project Deliverables • Detailed installation instructions • Parts for installation • MOXA CP-118EL serial board • Requires a PCI express slot on motherboard • DB9 serial connectors • Software package to control the system • Documentation and Instructions • Installation • Calibration • Operating Team Zap Gap - LSV2 Charger Remote Control
