Overview The SAL-I project team
Marc Hammerton Jörg Seifert Xu Du Scott Messner
The overall objective was to develop a graphical user Interface for SAL.
What is SAL? Sensor Abstraction Layer (SAL)
interfacing tool for managing large networks of sensors.
Multiple, unique devices one uniform system.
Command-line interface Textual data only
Different sensors
Command-line interface
SAL Agent
SAL-I is a web-based user interface to SAL Graphical representation of raw data. Remote access from anywhere. Increased user acceptance.
Main Components:
SAL-I
ApplicationServer
WebInterface
What is SAL-I?
SAL Agent
Requirements Achieved General
Web-based Dynamic Operating System Information Web Service Interface
Support of Multiple Sensor Types i-Wire (temperature sensors, pressure sensors,
etc.) JPEG/V4L (web cams, etc.) SMNP (collection sensors)
Requirements Achieved (continued…) SAL interaction:
Display of SAL Information List of sensors List of commands for a sensor Sensor output List of protocols Display OS Information
Managing SAL Add/remove a sensor Add/remove a protocol
Piloting Sensors: Send commands to a sensor Change sensor configurations
Problems/Obstacles Team
Communication Knowledge
Technical Performance
Web Service Interface cancelled Cache implemented
Environment RMI/Application Server configuration Project configurations
Video/Image Display Raw data conversion Javascript limitations GWT limitations
Conclusions Project Result
Nearly all requirements fulfilled Client is satisfied with outcome
Project Management More difficult than expected Strong start and finish, weak transition
Final Statement: Minor setbacks but overall success!
