Abstract
An exemplary method of controlling a plurality of elevator cars includes determining that there is a security violation condition involving at least one of the elevator cars at a landing. That elevator car is prevented from moving from the landing until the condition is resolved. The other elevator cars are controlled such that they do not provide elevator service to or from the landing until the condition is resolved.
Claims18
A method of controlling a plurality of elevator cars, comprising the steps of:
- determining that there is a security violation condition involving at least one of the elevator cars at a landing;
- communicating an indication of the determined security violation condition to a controller associated with each of the other ones of the plurality of elevator cars;
- preventing the one of the elevator cars from moving from the landing until the condition is resolved;
- and
- controlling other ones of the plurality of elevator cars such that the other elevator cars do not provide elevator service to or from the landing until the condition is resolved.
