In this section you can find examples of projects that have been completed or are currently under development. For confidentiality reasons, the details, markups and photographs have been excluded.

Industrial Control

 

Industrial control systems are usually composed by several units separated by long distances. In many applications a main central server takes decisions and remotely controls a large number of devices of different types. These devices perform their duty either totally transparently or in semi-autonomous way and sometimes also control others sub-devices.
 
There are cases when the whole system can be composed by standard devices, but in many applications there are numerous constraints to be considered:
  • Integration into an existing system, when the communication protocols or the bus topologies cannot be changed
  • Physical constraints, when specific sizes and shapes must be followed
  • Technological constraints, like performances, costs, operating conditions
  • Many more: security and environmental regulation, maintenance, lifetime, etc....
 
In many cases it is necessary to develop specific devices in order to achieve the goals.
 
The project described in this section falls into this category, where the operating constraints have led to a highly integrated system with a sophisticated firmware, and composed by several addons boards (not listed here).
