  • signals such as from a EUDA control device, the ICUD 25 (or 125) or one or more HUFDs 24 (or 124) intended for transmission to the existing elevator machinery 150 or elevator controller 20 to the proper format and/or pinout of the existing elevator machinery 150 or elevator controller 20.
  • the UICD 30 or UID 31 generate signals for transmission to the elevator machinery 150 or elevator controller 20 which mimic the signals that may otherwise be sent to the machinery 150 or controller 20 by the elevator call buttons or elevator control panel.
  • such "mimic" signals from the system 10 are indistinguishable to the machinery 150 or controller 20 from the signals received from the elevator call buttons or elevator control panel.
  • the UICD 30 or UID 31 functionality can be built into other components - such as HUFDs 24 (and/or ICUDs 25 and/or other components of system 10 such as an independent control device) - so that the other components (or components of the system 10) can communicate directly with existing elevator machinery 150 or elevator controller 20.
  • data from the IUPS 23 may be communicated directly or indirectly to one or more HUFDs 24 and/or the ICUD 25 and/or the UICD 30 and/or other components of the system 10 (see, for example the schematics from Figure 6 to Fig. 10 ).

  • the system may also comprise an application (or app), in some instances termed the Elevator Universal Digital Assistant app 33 that can be downloaded to a user's mobile phone 8.
  • the user can be prompted to download the app 33 as the user approaches the elevator and the app 33 may be wirelessly downloaded from a HUFD 24 or other component of the system 10.
  • the app 33 can be otherwise downloaded through various techniques such as from an app store, or triggered when the user enters the building or structure.
  • the app 33 can be loaded into the mobile phone 8 to be used at any of a plurality of elevator installations wherever the user goes so long as the "other" elevator systems utilize the EUDA systems.
  • control system 10 can be universally fitted to virtually any elevator system, a single application 33 can be used at a plurality of elevator installations (which use an embodiment of control system 10). Accordingly, in some embodiments a single user may use the same mobile phone app 33 in almost every installation of the present universal independent digital control system 10.
  • the HUFD 24 and the ICUD 25 devices may include a smart reader or other communication systems to interface with the user's mobile device 8. Such communication systems may include Bluetooth and other local wireless data communication protocols and systems.
  • the system 10 comprises an independent control component in functional communication with other components of the system 10.
  • the independent control component is configured to process received signals corresponding to elevator passenger call inputs, passenger floor destination inputs, and elevator vertical position data and generate an elevator car travel itinerary based on the processed signals.
  • the independent control component generates command signals for transmission to the elevator controller to cause the elevator controller to provide elevator car service conforming to the generated elevator car travel itinerary.
  • the independent control component further dispatches the generated command signals, or signals representing the same, such that they may be communicated to the elevator controller.
  • the UICD 30 may comprise the independent control component.
  • one or more HUFD 24 (or 124) may comprise the independent control component.
  • the ICUD 25 (or 125) may comprise the independent control component.
  • the independent control component may be comprised as a component other than an HUFD 24, UICD 30, or ICUD 25.
  • the itinerary maybe a straightforward response to the passenger's call for service.
  • the generated itinerary may be a simple command to dispatch the elevator to the first floor so as to pick up the passenger.
  • the itinerary may comprise the simple dispatch to floor 1 and, so, the itinerary may be spoken of as being "identified" (from the service call) and then transmitted to the elevator controller.
  • the itinerary may become more complicated and, so, may be spoken of as being "generated” by the control component.
  • the control component may generate an itinerary that adds stops at both floor 4 and floor 3 and transmit appropriate itinerary commands to the elevator controller so that the elevator stops at floors 4 and 3 to pick up the descending passengers at those floors. It can be seen in this fashion that the control component may receive and process inputs from service calls and target floor destinations and also process data from an elevator vertical position sensing system to generate travel itineraries to meet the passenger requests and while yet complying with order of service command protocols that may have been provided to the control component.
  • one or more control components may singly or cooperatively generate separate itineraries for each of the elevators to provide optimized service to the passengers presenting to the system. Further, itineraries may be generated that take into account priority of passengers or priority of floors serviced or other rules or priorities as may be defined and provided to the elevator controller from time to time.
  • the system may comprise an independent interface component configured to groom dispatched command signals from the independent control component such that the groomed command signals mimic signals received by the elevator controller from the first floor devices and the first car control input panel.
  • the system 10 is configured such that the groomed dispatched command signals from the independent interface component may be communicated to the elevator controller.
  • the independent interface component may comprise the UID 31 (or 131) and may comprise a separate device in the system 10 or may comprise functionality otherwise embodied in other components of the system 10, such as a HUFD 24, the ICUD 25, and/or the UICD 30.
  • Figures 1.a.1 and 1.a.2 illustrate embodiments wherein a separate IUPS 23 device is utilized as part of the system 10. Each of these Figures also shows, as indicated in the notes on the Figure, a configuration wherein optionally a separate UID 31 or UICD 30 may be included or omitted. Also, in each of these Figures, as explained in the legend, the dotted line indicates communication via wired, wireless or pre-existing wire systems.
  • Figure 1.a.1 illustrates an embodiment with a separate IUPS 23 wherein the system 10 also includes HUFD's 24 and an ICUD 25.
  • Figure 1.a.2 illustrates an embodiment with a separate IUPS 23 but without any HUFDs 24.
  • Figure 1.a.3 illustrates an example not within the scope of the claims, which does not include an ICUD 25.
  • FIG. 2 illustrates an exemplary embodiment of an UICD 30 having a functional printed circuit board (PCB) 34 having memory, processor, firmware and software and configured to receive and process data communications from one or more HUFDs 24 and may also receive and process data from other system 10 components such as the IUPS 23 and ICUD 25.
  • the PCB 34 may be configured to process signals received and send signals to one or more of analog interface board 36 or serial interface board 38. Signals from either or both of the analog interface board 36 or serial interface board 38 may then be communicated to the elevator controller 20.
  • PCB printed circuit board
  • the signals from UICD 30 to elevator controller 20, in some embodiments, may be fashioned to replicate or mimic the signals the elevator controller 20 normally receives from the elevator call buttons or those signals from the elevator internal control panel which represent the designated or target floor selected on that internal control panel by the elevator user (or other signals from the existing call buttons or control panel(s)).
  • Figure 2 shows interface board 36 outputting signals "1", “2", “3", “4", and "5" corresponding to call signals or target floor destinations of any of illustrative floors 1 through 5.
  • signals (of elevator "call” and target or designated floor selection) passed to the elevator controller 20 from the universal independent control system 10 (via the UICD 30) are, in particular embodiments, identical to and indistinguishable (to the elevator controller 20) from those signals which would be otherwise received at the elevator controller 20 from the first elevator call buttons or elevator internal control panel. Accordingly, the addition of the universal independent digital control system 10 of certain embodiments of the present invention can simply "lay over" the existing signal input to the elevator controller 20 and do so without altering any of the designed safety or operational steps programmed into and followed by the elevator controller 20 once it has received signals from either call buttons or elevator internal control panels (or digital system 10).
  • the universal independent control system 10 can, via UICD 30, also pass a variety of other predefined signals to elevator controller 20 (such as emergency stop or other signals).
  • the UICD 30 or UID 31 may be integrated into one or more HUFD 24 and/or ICUD 25 and thereby the HUFD's 24 or ICUD 25 may communicate directly with the elevator controller 20 without using a separate UICD 30 or UID 31.
  • an ICUD 25 with integrated UICD 30 or UID 31 functionality can be connected directly to the first communications system in the elevator car (such as at or by way of the circuits and button circuits of the elevator car control panel) and/or can also communicate with the elevator controller 20 (or other components) via the second communications system.

  • the analog outputs of analog interface board 36 may be connected to relays (not shown) of the elevator controller 20.
  • the elevator controller 20 (absent the present invention) may control movement of the elevator car 12 to a destination floor by outputting an analog signal to the connected relay assigned to the destination floor, with a separate relay dedicated to each floor served by the elevator.
  • a separate conductive connection is made from the analog interface board 36 to each of the separate relays.
  • the analog output from analog interface board 36 corresponding (for example) to floor 3 may be connected by an electrical conductor to the elevator controller 20 relay assigned to floor 3.
  • each of the other analog outputs from analog interface board 36 may be connected by an electrical conductor to the elevator relay corresponding to the appropriate analog output.
  • the control system 10 can send analog signals, duplicative of (or mimicking) those otherwise sent to the relay by the elevator controller 20, to direct the elevator car 12 to any of the floors assigned to the relays. In some embodiments, there will be no difference in the analog signal received by the relays between those originating from the original controller 20 or the analog interface board 36 of the present invention.
  • the addition of the universal independent digital control system 10 of certain embodiments of the present invention can simply "lay over" the existing signals input to the elevator controller 20 and do so without altering any of the designed safety or operational tasks programmed into and followed by the elevator controller 20 once it has received signals from either call buttons or elevator control panels (or digital system 10).
