Ausgelegt ist dieses Web-Portal, das Ende
des 1. Quartals 2010 auf dem Markt verfügbar
sein wird, für alle, die den Betrieb kleiner
dezentraler Anlagen oder Maschinen
wirtschaftlich überwachen möchten.
The costs for purchasing and operating
equipment are significantly reduced by
using a web portal. The use of security
standards can continue to protect communication
from unauthorized access.
The proposed project is an example of the
trend towards "remote control via Internet"
with respect to web-based process monitoring
and control in water management.
Innovative communication
With the introduction of the new HydroDat
V8 process control system for urban drainage
in Frankfurt am Main, all 67 existing
special structures that had been linked via
analog dial-up lines to the central control
station were changed to modern GPRS
transmission with Internet technology.
Powerful embedded control
The transformation of the process signals
into the TCP/IP protocol incorporate HST
Telematic SMART-200 embedded controllers
which combine the PLC and industrial
PC technology in one device. Unlike other
approaches, where the TCP/IP protocol is
already being changed by an intelligent
22 M2M Journal 04 | 06/10
modem into a serial protocol, it stays
available in the TeleMatic-System and
transparent all the way to the controls.
It has been proven to be an advantage that
the online and archive data is processed
separately in the software. This way, all
measurement data which is to be archived
can be directly saved onto the substation
for up to 6 months after the delta-event procedure
and upon connection can automatically
be sent to the process control system.
The extensive and freely configurable archiving
procedure needs no compression,
is therefore loss-free and forms the basis
for an optimal analysis of the process.
High investment security
The openness of the system is secured in
such that the coupled embedded controls
exchange their data by way of the OPC with
the process control system. This interface
allows other processes to be integrated
into the process control system or the process
data of the HST stations to be transferred
into another visualization system.
Conventional remote control technology in
the field of wastewater is being increasingly
replaced through the meshing of local
networks with web technology. Since the
basic communication structure remains
the same when there are changes such as
the transmission path, a safe and sure investment
for the future is assured.
Secure communications
All TeleMatics stations connected with
GPRS communicate virtually in real time
from a VPN connection furnished by a
GPRS provider and are encrypted with the
process control system at the control center,
which is equipped with a VPN router.
Kommunikation zwischen GPRS-Station,
Server und Anwendungsclients.
Communication between the GPRS
station, server and application clients.
Save costs by using a web portal
To save costs, the operator can alternatively
access a web portal at his own control
center. This web-based monitoring system
provides simple control functions, such as
how to monitor and operate the pumping
stations, and how to evaluate the data collected.
Furthermore a malfunction alarm is
available. The portal itself is operated from
a data center, which provides the necessary
communication structure and ensures
high reliability. Each of the remote control
stations are securely connected with the
Internet via the respective GPRS provider
by means of VPN and encryption. Because
the web portal’s server also has a permanent
link to the Internet, the remote station
can transmit the collected data directly to
the server to be archived. At the control
center, the remote control stations are connected
again via OPC server to the monitoring
system. This ensures that remote control
stations of various manufacturers can
be used. The communication between the
panel and control center is Internet-based
and occurs via GPRS and UMTS, EDGE,
DSL, etc. The user can access the web
portal with a browser from his workplace
through the Internet. The data is displayed
in a user-dependent manner and is available
as tabular overview, message archive,
time variation curve, or animated image
process.
Thus, a cost-effective connectivity is realized
by remote control stations. There are
no investment costs for the data center
and there are no complex purchasing processes
or administrative expenses for the
user. Invoicing occurs as a fee on a monthly
basis, rendering the maintenance costs
low and predictable.
This web portal is available on the market
at the end the first quarter of 2010 for all
those who want to monitor small decentralized
systems and machines economically.
