摘要:
An elevator system (20) includes multiple elevator cars (22, 32) within a hoistway (26). Counterweights (24, 34) are associated with the respective elevator cars (22, 32) by load bearing members (40, 50). In some examples, different roping ratios are used for the load bearing members (40, 50). In some examples, the lengths of the load bearing members (40, 50) are selected to allow contact between the counterweights (24, 34) within the hoistway (26) and prevent contact between the elevator cars (22, 32). The difference in car and counterweight separation distances is greater than a stroke of a counterweight buffer plus an expected dynamic jump of the elevator cars. A disclosed example includes passages (80) through a portion of at least one of the elevator cars (22) for accommodating the load bearing member (50) of another elevator car (32) located beneath the elevator car (22) with the passages (80).

摘要:
A plurality of hoistways (11, 12) in a building serving a plurality of floors utilizes destination call entry panels (22, 22A) having buttons (23) with which passengers can enter destination call requests. A display (26, 26a) adjacent the request buttons provides an indication of the car that is assigned to answer the passenger's request by a controller (27), which indication is also presented on illuminatable signs (16-19, 40, 41), utilizing either colors, letters or other easily identifiable and rememberable indications. As the car assigned to the call approaches the landing upon which the call was made, an illuminatable sign, adjacent the hoistway of the assigned car, will present the same color or indicia as was presented to the passenger upon entering the passenger's desired destination; the controller does not announce approaching cars that are not assigned a call at that landing.
摘要:
Destination calls entered by means of buttons (21-29) are each given a designation unique to the car and pick-up floor for that call and other calls to be serviced therewith, such as a letter (A-E), which is different from any other outstanding calls. Calls can be reassigned among elevators (UL, LL, UR, LR) whether they are in the same or different hoistways (LF, RT). Signs (31-39, 41-49) adjacent each hoistway are illuminated to display the designation of any call which is being answered by an elevator car approaching the floor Thus, passengers are informed when their call is being answered by the signs identifying the call, rather than identifying any particular car. Another embodiment identifies (60, 31a, 41a) the hoistway landing doorway (1, 2) as well as a letter to allow passengers to wait adjacent to the hoistway landing doorway of the car which will serve them.

摘要:
One of a plurality of cars (17, 18) traveling in a hoistway (10) of an elevator system (9) may be diverted to the hoistway overhead (31) or pit (36) to enable another of the cars to gain access to a floor near or at a terminal floor (11, 14). When such car is at its last stop with doors open, visual (40) and audible (41) indicators present (57, 58) messages to the effect that this is the last stop and passengers should exit. After car doors are closed (66), visual and audible messages (68, 69) relate to the car going to the pit or overhead and that passengers may push any button (to reopen doors). Thereafter, the car moves (75, 76) to the overhead (31) or the pit (36) and presents (82, 83) visual and audible messages to the effect that passengers did not exit at the correct floor and must wait while the other car makes a stop. Once the terminal floor is clear, the diverted car will run (87-89) to that floor, presenting (92, 93) visual and audible messages to the effect that passengers should exit once the doors are open and reenter their service requests.
摘要:
A method and apparatus for using a modified 8B/10B system for transmitting 10 bit wide data packets in 12 bit code in which 5B/6B encoder/decoders separate the 10 bit wide data into two 5 bit nibbles. Unique special codes are provided which are not capable of aliasing with other 12 bit code words to provide reliable byte boundaries.
摘要:
A method of assigning destination calls to cars (A-F) in an elevator system (20) having a plurality of hoistways (21-23) in which there is more than one car in each hoistway includes determining (33) the time for each car to respond to the call Among the cars with an acceptable response time, a determination is made regarding (34) the amount of additional delay in the hoistway that assignment of the call to one car will impose on the either car in the same hoistway. The call is assigned to that car which creates the least additional delay for cars in any hoistway.
