The SMG (Slotted
Microwave Guide)
data transmission system is suitable in automation technology for contactless
and interference-free transmission at high data rates up to
10 Mbit/s for all track-guided vehicles and opens up a wide range of
applications through its variable design.
General information
SMG was originally developed by
MBB (Messerschmitt-Boelkow-Blohm), now DASA (Deutsche Aerospace), to
transmit data to the magnetic levitation train
(»Transrapid«) traveling at speeds of up to 250 mph. VAHLE
acquired this product by the end of 1994 and now has over 1000
installations successfully in operation worldwide.
VAHLE has embarked
on an extensive development program to increase the SMG application
range. Presently there are already data interfaces available for the
most commonly used bus systems. Heavy-duty construction makes it
possible to install SMG in arduous and environmentally difficult
locations; for instance a great number of SMG waveguide systems are
functioning reliably in steel mills, foundries and harbors.
The SMG data transmission
system operates economically already with single channel transmission
and low data rates. Modular design easily expands the system to handle
at relativley low cost medium and high data rates as well as
multi-channel configurations. When combined with VAHLE conductor
systems for the current supply, SMG data transmission systems become a
reliable high-performance component package capable of handling a wide
variety of applications as demanded by current and future automation
technology.
