A method of interconnecting a daisy chain communication network having a terminal managers and a plurality of managed switches and a plurality of fixtures operable as clients of a client server network. The method also includes transmitting a discovery message to a first fixture and a second fixture, capturing the discovery message in the first fixture and the second fixture, and determining a first head fixture and at least one of a second head fixture and a tail fixture. Furthermore, the method also includes discovering an intermediate fixture based on the first head fixture and the at least one of a second head fixture and a tail fixture, resolving which of the first head fixture and the at least one of a second head fixture and a tail fixture is to be identified as an active head fixture, and establishing the active head fixture and a passive tail fixture.

Management of daisy chain connected communication network of elevator fixtures with redundant data paths

A method includes recording a primary destination dispatch request from a primary passenger at a first floor position via a destination dispatch controller, identifying a terminal floor, providing a terminal floor call signal to the elevator control system via an overlay controller, moving an assigned elevator car in a travel direction of the terminal floor, recording at least one secondary destination dispatch request from a secondary passenger at a respective at least one secondary floor position via the destination dispatch controller, approximating a position of the assigned elevator car, determining a target floor position via the destination dispatch controller, entering a target floor call corresponding to the target floor position at a calculated time to stop the assigned elevator car at the target floor position, cancelling all pending calls via the elevator control system, and entering at least one recorded destination dispatch request to the elevator control system.

Elevator control system overlay system

The disclosure herein includes a method for controlling elevators by an intelligent building system. The method includes receiving, by the intelligent building system, elevator calls initiated by passengers. Each elevator call can include a passenger identification corresponding to a passenger initiating the elevator call. The method further includes procuring passenger preference information based on the passenger identifications in response to the elevator calls and grouping the passengers with respect to the passenger preference information to produce passenger groups. The method further includes controlling the elevators to collect the passenger groups.

Intelligent building system for altering elevator operation based upon passenger identification

An elevator control system including an elevator management system obtaining meeting information from at least one of a calendar system and a user interface; the elevator management system generating a control command in response to the meeting information; and an elevator controller controlling destinations of one or more elevator cars in response to the control command.

Elevator control system using meeting information to control car destinations

An exemplary method includes distributing identifying tags to a plurality of potential elevator passengers so that each passenger has a uniquely identifiable one of the tags. Collective elevator system traffic information is determined based on monitoring movement of individual ones of the plurality of tags and corresponding elevator system operation.

Elevator traffic monitoring system and method

A method for controlling a fixture () includes receiving a message from a controller (), determining whether the message includes an address associated with the fixture (), retrieving an identifier of the controller () from the message responsive to determining that the message includes an address not associated with the fixture (), determining whether the fixture () includes a fixture channel () controlled by the controller (), and resetting a timer () associated with the fixture channel () controlled by the controller () responsive to determining that the fixture () includes the fixture channel () controlled by the controller ().

Timer-based control of fixture channels

A system and method automatically assigns unique addresses to devices connected on a communication bus based on the parameters measured by each device. Assignment of addresses may be provided centrally by a controller or may be distributed, in which each device negotiates with other devices to assign unique addresses to each device.
