System for measuring operational and energy parameters of lift installations used to determine their energy efficiency

This paper is focused on the data acquisition system for registering parameters of lift installations in terms of their energy efficiency (energy take by the entire installation, by the drive unit, the lift car elements, control unit, lift car door, halt doors) as well as operational parameters (lift car loading, ride direction, distance covered, kinematic parameters, service time). The main components of the measurement system (transducers) are briefly described and the results are given as registered operational and energy parameters of the lifting installation measured over the weekly duty cycle, defined by the users’ demand and usage.
