Abstract


Modern intelligent building complex and out of personnel , particularly large traffic flow , therefore, often configured in the building elevators , in order to improve the service quality and efficiency of the elevator system , so that the day-to-day operation of the building a harmonious and orderly . Elevator Group Control technology is an effective means to achieve this goal . Elevator group control system is a complex nonlinear system of decision-making of multi- target random uncertainty problem, we carry out this study has important theoretical and practical significance . The main content of this paper : 1 . Analysis of the existing elevator group control technology , combined with the characteristics of the elevator group control system , an elevator group control system solutions ; 2 . Established mathematical model of group control system based on Petri nets . Select three control objectives : the satisfaction of waiting , take the ladder 's satisfaction , loss of energy , elevator group control system , the control algorithm is designed based on three objectives : the multi-objective the smart scrolling optimal control algorithm , and the control algorithm for the simulation ; designed the overall structure of the elevator group control system , including the group control system workflow and implementation ; 4 . designed controller hardware part of the group control . Hardware systems to FPGA as the core , to complete its interface module , transceiver module design , and hardware platform with a strong anti-jamming capability . 5 . Designed the the controller software part of the group control . The use of the C language and VHDL language programming to complete the design of the control software . The modular design concept , relatively independent modules , and to facilitate the writing and debugging of programs . And group control system software architecture standardization study , to improve the flexibility and scalability of the elevator group control system purposes .
