Microcontroller application for wood-based
New technologies contribute to environmental care
|Industrial sector (PRODCOM code)
IMB Industrieofen- und Maschinenbau Jena GmbH is a SME with
30 employees having a long tradition in the development and manufacturing
of boilers for wood-based heating systems. Furthermore, the company offers
other products, e.g. stress relief furnaces used in the glass industry.
As a typical representative of the machine building industry sector of
the former GDR, the company has experiences and corresponding production
facilities in mechanical engineering, but there was no knowledge or experience
in microelectronics before the FUSE Application Experiment. IMB was a
real newcomer in this field.
The products of the company are used in heating systems for detached houses,
small company buildings with location in wood areas. Because of several
state programs for introduction of environmental care heating systems
these products are sold mostly in Germany but also in North- and East-Europe.
The objective of the experiment was the improvement of the competitive
position and a turnover increase by designing a microcontroller based
control unit for IMB's existing boiler product family "LIESTATHERM". The
product family covers a wide range of different power ranges and boiler
sizes and is used as a wood based heating system for detached houses,
but also for small and medium sized office buildings or workshops. The
substitution of the existing conventional control unit consisting of simple
switches and temperature controller by a microcontroller based solution
allows the implementation of additional service functions and enables
the system to work together with other heating systems (e.g. heat pumps
or solar heatings).
In order to guarantee the design flexibility which is necessary to adapt
the control unit to the special needs of one customer, and of course due
to economic reasons, it was necessary to install the corresponding microcontroller
know-how at IMB. Additionally, the work with a PCB CAD system had to be
learned in order to have all necessary know-how in this field available
for future projects. The result of the Application Experiment is a modular
control unit that can be used without hardware changes for the whole product
family only by doing software modifications. It is now possible to program
the heating process and to control a combination of different heating
systems. The improved product contains a PIC16C65 of Arizona Microchip.
For the programming and implementation, the development software MPLAB,
a PIC start programmer and a PID-Dem-Evaluation Board were used. The PCB
design was realised with the EAGLE system.
Within the experiment IMB acquired know-how in the management of projects
using microelectronics, especially PCB and microcontroller technology.
Because of the lack of any experience in this field, this was very important.
The main lessons learned referred to handling of the corresponding design
tools and best practice in design methodology. Furthermore, the engineers
of the company are now familiar with programming and application of microcontrollers,
PCB design, simulation and manufacturing as well as test strategies for
products based on these technologies.
The Application Experiment duration was 11 months. The total costs were
82K€ of which 44K€ was the FUSE investment. The payback period for the
FUSE investment will be in the range of 18 months. Assuming a life time
of 5 years, the total ROI for the FUSE investment will be about 780%.
