Abstract


With the continuous emergence of high-level intelligent building as a vertical elevator means of transport is becoming more and more important, more and more people on the elevator system performance requirements . Increase in the number of the elevator alone not only can not meet the requirements , such as environmental pollution , energy consumption , inefficient operation will also bring problems . In this paper, to improve the elevator group run efficiency and service the quality of as the starting point , were based on multi-objective planning scheduling algorithm of elevator group control system 's design , the main contents are as follows : 1 . Elevator passenger transport mode decision to the elevator group control system of scheduling strategy. The first category , the characteristics of the elevator traffic mode analysis, the use of fuzzy logic to identify the passenger traffic patterns in real time , to lay the foundation for the realization of multi-objective planning algorithm . Elevator Group Control System features analysis and research , common group control scheduling principles and multi-objective planning based on mathematical modeling Elevator Group Control System with multi-objective planning algorithm , considering the average passenger waiting time , the average riding time , the car congestion and the four main factors of the energy consumption of the system , the establishment of a multi-objective evaluation function , multi-objective planning algorithm design under different traffic patterns . The advantages and disadvantages for the RS485 bus together to build the elevator group control network , completed the hardware design of the elevator group control system with Ethernet and CAN bus ; modular program design thinking , the use of the C programming language , the completion of the elevator group the design and commissioning of the control system software . 4 . Using the Visual Basic language preparation elevator group control system simulation software simulation environment , and embed the minimum waiting time algorithms and multi-objective planning algorithm and simulation analysis . Finally, experimental platform , scheduling experimental group control system .
