Abstract

An elevator system including an elevator car having main and auxiliary car stations, each of which include pushbuttons for registering calls for service to various landings of an associated structure. The car calls are stored and serialized in the main and auxiliary car stations, and a single serial car call signal is provided in response to the serial signals from the main and auxiliary car stations. A serial set line is connected to each car station responsive to car calls originating at the other car station, simulating parallel interconnection of the pushbuttons of the two car stations by setting a call on one station which originated at the other station.

Claims

1. An elevator system, comprising: a structure having a plurality of landings, an elevator car mounted for movement relative to said structure to serve the landings, car control means including a main car station and an auxiliary car station disposed in said elevator car, means for registering calls for service to said landings from each of said main and auxiliary car stations, means storing the calls registered on said main and auxiliary car stations in said elevator car, means serializing the calls for service registered on said main and auxiliary stations, and serial call set means reyponsive to said serialized calls for service, providing a serial car call set signal for the main car station and a serial car call set signal for the auxiliary car station which set a call initiated on one of the car stations on the other of the car stations, to simulate parallel interconnection of the means for registering calls for service from the main and auxiliary car stations.

2. The elevator system of claim 1 wherein the means which serializes the calls for service includes first means for serializing the calls from the main car station, second means for serializing the calls from the auxiliary car station, and third means responsive to said first and second means providing a single serial signal which includes all calls for service registered on the main and auxiliary car stations, and wherein the serial call set means is responsive to the single serial signal provided by said third means to provide like car call set signals for the main and auxiliary car stations.

3. The elevator system of claim 2 including means for providing car call set signals from a point remote from the elevator car, wherein the third means is responsive to said remote car call set signals, incorporating the remote car call set signals into the single serial signal.

4. The elevator system of claim 1 including scan counter means which repetitively counts through a predetermined group of numbers to provide a plurality of timing signals which divide repetitive periods of time into a plurality of scan slots, with the landings of the structure being assigned to different scan slots, wherein the means serializing the calls for service places the calls into the scan slots assigned to the landings they are associated with.

5. The elevator system of claim 4 including means for providing car call reset signals in the scan slots associated with the landings, and means modifying the serial call set signals provided by the serial car call set means in response to said reset signals, to eliminate a car call set signal from a time slot in which a car call reset signal appears.

6. The elevator system of claim 1 including indicating means which visually indicates calls initiated on each of the main and auxiliary car stations, wherein the serial call set signal when setting a call on one of the stations also actuates its associated indicating means.

7. The elevator system of claim 1 wherein the means for registering calls for service from each of the main and auxiliary car stations includes pushbuttons.

8. The elevator system of claim 1 wherein the means which serializes the calls for service includes first means for serializing the calls from the main car station and second means for serializing the calls from the auxiliary car station, and wherein the serial call set means is responsive to the first and second means to provide a serial car call set signal for main car station responsive to the second means and a serial car call set signal for the auxiliary car station responsive to the first means.
