摘要:
A system and method for determining the availability of an elevator car for response to hall calls includes a plurality of infrared sensors disposed to monitor the presence of an object within an elevator car. The cross-sectional area occupied by an object, or objects, within an elevator car is determined by the number of sensors generating output signals based upon reflections of transmitted radiation from such an object. The system monitors the cross-sectional area availability of the elevator car and categorizes the car as to its availability for responding to a hall call.

A method and system for remote access to multiple subsystems (102) of an elevator control system (104) are provided. The method includes receiving a request to establish a remote connection at an elevator control subsystem (112) from a remote user system (110). The method also includes determining whether a local connection is established between the elevator control subsystem (112) and service equipment (120). The method further includes establishing the remote connection in response to determining that the local connection is not established between the elevator control subsystem (112) and the service equipment (120). The method additionally includes sending a time since the service equipment (120) was last active and providing an option to complete the remote connection in response to determining that the local connection is established, the elevator control subsystem (112) is operating in a first mode of operation, and a configurable local activity timeout period has not expired.
摘要:
An improved high speed magnetic tape duplicator incorporates superior features from both thermomagnetic and anhysteretic processes to increase productivity in operating economics. Starting with a basic transport configuration of existing thermomagnetic equipment, the heating and cooling facilities are removed along with the non-magnetic transfer drum, and replaced with a magnetizable drum assembly and bias-field head suitable to anhysteretic duplication. Provisions are also added to correct tension errors so as to minimize skew and the transport control electronics are preferably replaced with a personal computer-based controller capable of furnishing additional functional capabilities including production reporting. Optionally, the master-tape loop-bin chamber is also specially modified with electrically ground static-control provisions.
摘要:
An elevator system for up-peak servicing of a building having a dual lobby. The system includes a controller having an electronic processor coupled to a memory; a plurality of elevator cars controllably connected to the controller, a dual lobby routine stored within the memory, the dual lobby routine includes instructions for dispatching at least one of the elevator cars to a lower lobby during up-peak, indicating a sector assigned to the car, nudging (if needed) the car if a lower lobby time-out is exceeded, dispatching the car to the upper lobby if a load weight threshold is not exceeded, and then indicating the sector assigned to the car while the car is located at the upper lobby.
摘要:
The data processor (OCSS) 35 of an elevator car that can be transferred from a group 38 of elevators (a swing car) is switched out of a ring of similar data processors 31-34 into another ring of data processors 36, 37 which comprise a separate group 39 (FIG. 2 ). Or, the processor 35 can be swung from the group 38 into operation by itself in the simplex mode (FIGS. 3 and 4) when connected (66) to a separate hall call button and enunciator lantern riser 56.

摘要:
An improved push-push switch (10) suitable for complete automatic assembly is disclosed. The push-push switch (10) contains essentially two moving parts comprising an actuator (50) and a cam (60), the cam (60) coupled by keyway connections (63) for rotation with the actuator (50). Switch contacts (43, 47, 49) are located adjacent the moving switch parts in order to effect a make and break type of switch operation. The actuator (50) has interior (56) and exterior (54) gear teeth which mesh with cover gear teeth (36) and housing gear teeth (14), respectively, to effect rotation of the actuator (50) and the cam (60). The configuration of the cover gear teeth (36) and the associated interior actuator gear teeth (56) provide an axial over-travel of the actuator (50) without effecting any appreciable rotational movement of the actuator (50), thereby compensating for accumulated manufacturing tolerances without affecting switching functions relative to axial displacement of the actuator (50). Rounded and shape edged cam surfaces (64, 65, and 66, 67) produce the same tactile "feel" during the inward axial movements of the actuator (50), whether the switch contacts (47, 49) are being opened or closed.
摘要:
During elevator modernization, a cross-dispatching system receives hall calls and assigns each hall call to either a group of existing elevator car controllers or a group of new elevator car controllers. The cross-dispatching system creates an inter group relative system response (iRSR) value for the hall call for both the existing group of elevators and the new group of elevators, based upon information from each group such as car location, in-service status, load, and direction. If the group assigned the hall call does not answer the call within a redispatch time period, the cross-dispatching system again calculates the iRSR for each group and reassigns the hall call.

摘要:
A method and apparatus for dispatching elevator cars to hall calls in a system where there are two types of elevator controllers (12, 14) in operation, one (12) of which operates using relay logic. The calls are stored in a relay logic memory common to both elevator controllers (12, 14). A first controller reads the call information directly from the memory (18); the second controller reads the memory through a cross cancellation device (10) which multiplexes the information from the memory so that the calls are provided on a serial link (32) to the second controller (14). The second controller (14) is programmed to respond to calls which the first controller (12) has not answered.
