EZStream: The Internet-based System for
Real-time Data Monitoring
AZ
Technology's EZStream uses standard Intranet/Internet
technology and personal computers to inexpensively
automate the real-time collection, distribution,
and visualization of real-time data. International
Space Station (ISS) experiment payload status
can be displayed through the Internet from
any standard Web browser such as Internet
Explorer or Netscape Navigator. EZStream
is currently designed to accept a data stream
from the ISS Telescience Resource Kit telemetry
application.
Features and Benefits:
- Server written entirely in Java for
portability.
- NO FIREWALL ISSUES: Uses HTTP for data
distribution.
- JavaBean and ActiveX components available
for application/web interface.
- Server runs on a standard Pentium 550.
- Client runs on ordinary desktop computers.
- One TReK server feeds multiple remote
displays.
- Internet data distribution to anywhere
in the world.
- Easy to setup and use.
- User Authentication for security.
- Great way to fulfill NASA Education/Public
Outreach requirements.
" From Space to your desktop..."
EZStream brings the power of the Telescience
Resource Kit to remote desktops
The Telescience Resource Kit (TReK), a software
package developed at NASA Marshall Space
Flight Center, is the EZStream "engine".
TReK was developed to make it easier for
researchers to access payloads on-board
the International Space Station from standard
laboratory computers. AZ Technology Technology
has developed a web-based data server called
EZStream, which turns a TReK PC into a Web
server, allowing authorized Web users to
become live observers of ISS experiments.
Works with Standard Display Development
Tools
C/C++, JAVA, Visual Basic, National Instruments
LabView
Commercial Applications: EZStream is well
suited to commercial applications, such
as industrial automation, SCADA, telemedicine,
and home automation. AZ Technology is actively
seeking partners to pursue commercial applications
of the EZStream technology.
EZStream For Automation and Manufacturing
EZStream can allow easier and broader access
to process control and factory automation
data. Data  sources
can be enhanced to allow EZStream to select
which data should be published and then
supply that data in a standard EZStream
format. A typical SCADA system can be enhanced
to act as a web/data server so that its
data can be displayed remotely. Operators
and automation experts will be able to view
and control (fine tune) the factory of the
future from anywhere in the world. Real-time
data will be distributed easily across the
Internet so quality assurance, accounting,
auditing, management, and engineering personnel
can receive up to the minute status of automated
factory operations.
