Abstract
An elevator system includes a controller; an elevator car; an elevator car controller mounted on the elevator car; a transceiver on the elevator car; an access point; the transceiver and the access point configured to provide wireless communications between the controller and the elevator car controller over a first communications path and a second communications path.
Claims13
An elevator system comprising:
- a controller;
- an elevator car;
- an elevator car controller mounted on the elevator car;
- a transceiver on the elevator car;
- an access point;
- the transceiver and the access point configured to provide wireless communications between the controller and the elevator car controller over a first communications path and a second communications path;
- wherein at least one of the controller and the elevator car controller is configured to:
- detect a quality of the first communications path;
- compare the quality of the first communications path to a threshold;
- communicate primary information over the first communications path when the quality of the first communications path meets the threshold;
- communicate secondary information over the second communications path when the quality of the first communications path meets the threshold;
- switch communication of the primary information from the first communications path to the second communications path when the quality of the first communications path does not meet the threshold;
- and
- switch communication of the secondary information from the second communications path to the first communications path when the quality of the first communications path does not meet the threshold.
