Abstract
A group supervisory control system for an elevator which statistically operates to obtain traffic data on the elevator for time zones divided in the previous operation and controls the driving operation of cars based on thus obtained statistical data and which comprises a traffic data recording circuit for recording the traffic data of the elevator for the previously divided time zones and a time zone setting device for setting time zones when a predetermined condition concerning the data recorded in the traffic data recording circuit is established.
Claims4
A group supervisory control system for an elevator in which a day is divided by a plurality of time zones, and in which traffic and service data for an elevator are statistically gathered for each time zone in the past time and the driving of cars are controlled based on the statistical data, said control system comprising:
- traffic data recording circuit for recording the traffic data of the elevator for a plurality of time zones;
- reference setting means for determining a reference value;
- time zone setting device responsive to said traffic data recorded by said traffic data recording circuit and said reference value wherein said time zone setting device includes a comparator for comparing said recorded traffic data and said reference value and wherein said time zone setting device outputs a signal for setting a new plurality of time zones.
