| Peak Period Service 
The up- and down-peak features are placed in service
automatically by demand on the system. When desired, however, building management can
adjust the timing of up-peak and down-peak operation through the use of preset programs.
During normal traffic periods, the system saves energy by
shutting down cars not in use. They remain shut down until the Miconic A system senses an
increase in traffic.
Up-peak traffic:
matching cars to demand
The Miconic A system detects up-peak traffic by monitoring
the demand for elevators and the passenger loads at the main lobby. As required, the
Miconic A system sends additional cars to meet the demand. Dispatching is regulated to
provide optimum departures and maximum loading.
To serve the occasional down demand during up-peak periods,
the Miconic A system selects the car least likely to disturb up-travel intervals.
Down-peak traffic:
a time sequence program
During down-peak traffic, the Miconic A system gives
preference to down calls above the lobby by allocating more cars to this service and by
limiting service to counter-flow traffic. As down traffic increases, the dispatcher limits
the number of corridor calls each car will be permitted to serve. Regulating the car to an
optimum number of stops increases the system's overall passenger moving capability. |
