Abstract
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 …
