Lifts play an important role in human transportation in multi-storage buildings, which experience continuous improvements to their architecture and structure. As a result of these improvements, the development of efficient lift systems with more programs is required to meet these changes. In this work, a lift control system based on a programmable logic controller (PLC) is introduced, elucidating the development of the lift control algorithm and network based on a dispatching algorithm that utilizes a fuzzy system and exploits the traffic situation and condition. The PLC language ladder logic is implemented to facilitate a reduction in the average waiting time of passengers and the power consumption. Ladder diagrams for different scenarios are compared. The analysis of personnel-machine-environment (P-M-E) system conditions was conducted, examining numerous physical factors that could pose health and safety threats to workers. The present study opens doors for future lift systems studies based on PLC and the estimation of a safe workplace for machines and operators. View Full-Text
