Group manage system for elevator

Abstract

The elevator group supervisory system includes a group supervisory control apparatus for supervisory control of respective groups of elevators; respective unit control apparatus for controlling each group of elevators respectively; and a hub with a built-in input / output apparatus section for transmitting information to and receiving information from hall devices by connecting the group supervisory control apparatus and the respective unit control apparatus with a bus communication line, has information exchanged with the hall devices shared by the group supervisory control apparatus and the respective unit control apparatus, transmits information received from the hall devices to the group supervisory control apparatus if the group supervisory control apparatus is operating normally, and transmits information received from the hall devices to the respective unit control apparatus if the group supervisory control apparatus is operating abnormally.

Description

technical field [0001] The present invention relates to an elevator group management system including a plurality of control devices for individually controlling each number car of an elevator and a group management control device for controlling an elevator group. In particular, it relates to control of input and output information in a plurality of individual control devices and a group supervisory control device. Background technique [0002] Figure 4 A configuration diagram of a conventional elevator group management system shown in, for example, Japanese Patent Application Laid-Open No. 4-55272 is shown. exist Figure 4 Among them, 2 is a group management control device for group management control of multiple elevators, 3, which are collectively referred to as 3a and 3b, is each control device for controlling each number machine of the elevator, and 4 is a call button installed on a landing, etc. 10 is a star-shaped communication line connecting the group management ...

AI Technical Summary

Problems solved by technology

[0011] Because of the above-mentioned structure, the group management system of the elevator in the past, so when the group management control device 2 that controls the elevator group stops, it can only respond to each control device 3a for the hall equipment 4, so that the group management system of the elevator Overall service down

[0012] In addition, since the switching device 11 for switching the connection point to the hall equipment 4 from each control device 3a to the group supervisory control device 2 is provided, even if each station control device 3a stops, the group supervisory control device 2 can Response landing equipment 4, so the cost increases

This has the same problem not only for the connection of landing equipment 4, but also for the connection of extension equipment and external equipment of the group management system of the elevator
