Control system for controlling e.g. door drive by aged person in hospital, has stationary units coupled with load in installed position, and portable unit building wireless connection with another portable unit to execute function

摘要

The system has stationary units (6-19) electrically coupled with an electrical load in an installed position. A wireless connection is produced between the stationary units and portable units (20, 21). The stationary units detect a preset user action e.g. door opening action, via the wireless connection and release preset load actions as a reaction via the electrical connection with the load. One of the portable units builds the wireless connection with the other portable unit for executing an additional function e.g. loss prevention function. The portable units have a radio frequency identification (RFID)-Chip for executing the additional function.
