Microcontroller based elevator controlling system

This paper introduces a new solution of elevator controlling system which is based on microcontrollers. The earlier version of it is still used by Schindler Hungaria Kft. Thanks to the innovation the point-to-point connections (the number of cables and so the cable length) could be dramatically reduced. In addition the ability to repair and the modularity has been also improved. The complexity of the system has been simplified and the costs could be lowered also. Until today a demo elevator system has been made which consists of three storey (called EIF) card. One of these executes the tasks of the main controller (so called IF). For both card types a control software was developed in C programming language, whereby the new system capacities could be demonstrated.
