【Abstract】 This paper presents the design of FI₃ type group supervisory control system of elevators which developed on the basis of HITACHI VFMG/VFHG elevator’s control system. The elevator’s software and hardware have been improved partly. As a result, each elevator of the group supervisory control system is connected by bus, so there is no upper processor in the system. The cost is thus greatly reduced.更多还原
