Research Of Elevator Group Control System Based On Intelligent Control

With the fast development of construction and the increase of mansions in cities, elevator, as a vertical transporting facility is more and more widely used. More and more attentions are paid to the elevator group control technology. In order to improve the elevator's running efficiency and service quality, this paper designs an elevator group control system based on the CAN bus, and realizes the multi-target planning intelligent dispatching algorithm according to the different traffic pattern. The main contents of the research are as follows:1. After systematically studying and researching the characters of elevator group control system, group control dispatching algorithm and multi-target planning, this paper proposes a new mathematic model for elevator group control algorithm based on multi-target planning, and establishes an multi-target evaluate function, considering the average waiting time, average riding time, the crowded degree of the car and the power consumption of the system. A multi-target planning intelligent dispatching algorithm is designed which can be applied in four different traffic patterns: Up-Peak Traffic Pattern, Down-Peak Traffic Pattern, Random Inter-Floor Traffic Pattern and Idle Traffic Pattern.2. An elevator group control net based on CAN bus technology is constructed and its corresponding hardware is designed, considering the advantages and disadvantages of the CAN and RS485 bus.3. Modular programming designing and C program language are adopted in the process of system software designing and debugging. The least waiting time and multi-target planning intelligent dispatching...
