Brief Project Description: The Automated Control of Shipboard Ventilation Systems (ACSVS) was a research and development effort for the Naval Research Laboratory’s (NRL) Research Facility, the ex-USS SHADWELL. This effort included engineering in controls and mechanical/ventilation and system installation, testing, and reporting. The purpose of the ACSVS was to test the concept of using automated ventilation for smoke control during wartime and/or peacetime damage scenarios onboard Navy ships. · The control was designed on a LonWorks peer-to-peer network using LonPoint I/O hardware. The network consisted of a variety of sensors, actuators, and variable frequency drives (VFDs). Communications were via a fiber optic backbone. The Human Machine Interface (HMI) provided monitoring and override control through a web browser interface. · The peer-to-peer network allowed the smart field devices to control automatically without the need for a master controller (PC, PLC, etc.). However, override capability was integrated into the HMI interface. · During damage scenarios, the control system would recognize the situation and automatically reconfigure the ventilation system (through actuated dampers) and control the VFD driven exhaust fans. · The control system was also designed to switch between automatic control, a predefined smoke ejection system (SES) mode, and a peacetime normal operations mode. |
