Abstract
An elevator system including a group control function section which provides a control instruction for managing the operation of elevators in accordance with demands or conditions based on various kinds of information such as status information of a plurality of elevators and generated hall call information, unit control function sections, provided for respective elevator cages, for controlling the elevators based on the instruction from the group control function section, and a monitor control function section, capable of exchanging information with the control function sections, for monitoring the entire elevator system. The control function sections are connected through a network, and a plurality of logical communication paths are set in the network. Logical connection relationship using independent logical communication paths are established for respective inter-control processes, so that inter-control process communications are executed using packets at high speed. The communication packets are sent to the logically connected control processes, thus realizing control functions of the elevator system.
