An elevator system having a plurality of elevator cars under group supervisory control. An auxiliary dispatching control is connected to the existing telephone system of the building, arranged to enable callers to have cars dispatched to predetermined floors at selectable times of the day.

Elevator system

An interactive, real time elevator bank simulation system including a display panel, dispatcher control, and a processor unit. The display panel includes illuminable control devices and illuminable display devices which are controlled to represent movement of the various elevator cars of the bank. The control devices enable an operator to interact with the system, such as by entering traffic requests, and to observe in real time the results of the requests on the operation of the elevator bank. The operator initiated requests are processed by the processing unit, and the processing unit controls the illumination of the operator actuated control devices on the display panel. This positive feedback arrangement provides optical acknowledgment to the operator that his request has been received by the processor unit.

Elevator bank simulation system

A monitoring system for off-site monitoring, traffic study and/or trouble shooting of elevator installations. Communication between the remote monitoring site and a selected elevator installation is established via a direct dial telephone link. The remote monitoring site includes visual display means for displaying the operation of the selected elevator installation in real time, means for storing and analyzing status signals from the elevator installation, as well as for printing out the results of such an analysis, and control means for entering commands to be executed by the elevator system. In addition to observing the operation of the complete elevator installation, any combination of software and/or hardware at the elevator installation may be selectively monitored by substituting a system processor and/or simulated car controllers, both of which are located at the monitoring site, for those located at the elevator installation, and operating selected components at the elevator installation along with those at the monitoring site via the communication link. The operation of the resulting hybrid system including its response to commands initiated at the monitoring site may be displayed and/or analyzed, as desired.
