Definitions

  • the present invention relates to elevator systems and more particularly to informational displays for elevators in which information on, inter alia , the status of an elevator car is displayed in, for example, the car itself and in the hall, especially at the main floor or lobby.
  • car information displays at, for example, the main floor landing or lobby, including which direction the car is moving in, i.e. , "up” or “down,” and to indicate at what floor the car is then currently located.
  • car information displays at, for example, the main floor landing or lobby, including which direction the car is moving in, i.e. , "up” or “down,” and to indicate at what floor the car is then currently located.
  • two, separate, illuminated displays one located at each car entrance indicating the direction of travel of that car in the form of a hall lantern and an integrated, illumi­ nated display with separate row of lights for each floor and with a separate column of lights for each car.
  • incandes­cent bulbs for the display In these displays it is the typical practice to use incandes­cent bulbs for the display.
  • the floors which the car (or cars) serves is usually displayed permanently near the respective car(s) at the main landing.
  • a brass plate may be located near a bank of elevators that reads "SERVING FLOORS 30-35," limiting the assignability of the cars or making information displays for varying assigned cars a difficult challenge for the building owner.
  • the present invention is designed to overcome these short-comings and to provide in contrast a cost effective, reliable, flexible elevator car information display system, which can handle all types of elevator applications, with the type of displayed information being easily changeable, even after the display has been installed in a building. Additionally, it is an object to provide such a display, which will allow the displaying of supplemental information not directed to information concerning the status of the elevator cars themselves.
  • the present invention utilizes an electroluminescent display (ELD) system to provide apparatus by which, inter alia , certain, varying elevator information can be conveyed to the public via a flat-panel, electroluminescent, raster-type display (ELD) panel or screen.
  • ELD electroluminescent display
  • the present invention provides an elevator display system which is designed to provide dynamic video information to passengers in the car and/or the lobby or other main floor using EL display screens.
  • Such a display is relatively flat, allowing for flush or near-flush wall mounting, and is bright, has good viewing angles and a relatively long life expectancy.
  • the type of information the ELD provides is divided into two categories - - elevator related information, including floor position, direction of travel, hall lantern, "jewel” messages and channeling range; and - building related information, including directories, messages (advertising), time and temperature, relative floor position and, if so desired, logos.
  • Each of the information types preferably is displayed at assigned locations on or portions of the EL screen.
  • ELD system in each car and one ELD in the lobby (or other main floor) for each car.
  • An additional remote screen which preferably displays the same information as the primary screen, may also be made available.
  • the ELD preferably is controlled from two sources.
  • the elevator management or monitoring system if it exists in the elevator system, communicates commands and data to the ELD via an appropriate communications link (e.g. , an RS-485 serial communication link). For the most part these commands cause the ELD to store and display on the screen the building related information.
  • an appropriate communications link e.g. , an RS-485 serial communication link.
  • the ELD also receives serial display information (discrete and data) from a remote serial link (RSL). This path provides the information required for the ELD to display the elevator related information.
  • serial display information discrete and data
  • RSL remote serial link
  • the basic display elements of the ELD system of the present invention typically will include the following interconnected components: an ELD glass (screen); an ELD interface printed circuit board (PCB) mounted behind the glass; an ELD remote station interface PCB (directly connected to and mounted on the ELD interface PCB); and an ELD power supply assembly (typically in a separate enclosure located within, for example, twenty feet of the other three components, with the other three components mounted together in a framing structure).
  • ELD glass screen
  • PCB printed circuit board
  • ELD remote station interface PCB directly connected to and mounted on the ELD interface PCB
  • ELD power supply assembly typically in a separate enclosure located within, for example, twenty feet of the other three components, with the other three components mounted together in a framing structure.
  • the ELD receives commands and data from the EMS, which cause it to display specific information or to receive downloaded data required for later display com­mands.
  • the ELD system includes particularly efficacious informational displays, preferably with the elevator related information displayed at the top portion of the screen and building information displayed at the bottom portion of the screen, preferably with the two portions divided by a horizontal line.
  • building information can include, as noted, building directory information, advertising messages, logos, etc .
  • the ELD system thus, preferably, includes a flat panel raster display and an associated display controller which receives and displays the following information from the elevator system at various times during the elevator run: - floor number position - relative position of the car in the hoistway - hall lantern (car arrival) - dispatching information - directories - time/temperature - messages (ads) - custom logos
  • a main computer in the elevator machine room preferably makes all dispatching decisions.
  • Standard RS-422/485 serial communication preferably is used for relaying elevator dispatching information to each display.
  • This port is also used to convey directory and message information to the display. Since one port of the machine room computer is used, each display is addressable. In this way, information relating to a particular elevator display can be extracted from the "party line" by using addressed "packets" of information.
  • the invention may be practised in a wide variety of elevator applications using a great variety of circuit and electrical or electronic components, in the light of the teachings of the invention, all of which are discussed in further detail hereafter.
  • An electroluminescent display (ELD) screen typically is in the form of a flat, glass panel, with the display having a matrix of pixels, each of which in operation is either turned “on” or “off” on command, producing variable, relative darkened and lightened areas on the screen to display graphical or textual images.
  • An exemplary embodi­ment useful with the system of the present invention is an EL screen having a matrix using a "640 X 200" format, having an exemplary size of 4.8" X 7.7" (122 X 196mm).
  • An additional remote screen which preferably displays the same information as the primary screen, can be mounted up to, for example, 25′ (7.62m) away from the primary screen.
  • a remote screen is particu­larly useful for, for example, a "double deck” car system, with the "primary” display at one deck and the “secondary” or remote display at the other deck.
  • the glass screen preferably is mounted as flush to the wall as possible and located as near as possible to the elevator or elevator group which it serves. Such flush mounting is likewise desirable in the car display, with the display aesthetically placed as near or above the car operating panel(s) [COP(s)] as feasible.
  • the interface boards for the screen are located as near as possible to the display, while preferably remaining out of sight to the public.
  • the ELD system of the present invention preferably includes a serial communication link to the EMS, which can be in the form of shielded twisted cable pair(s).
  • This wiring is preferably brought down through the travelling cable for each elevator car, and through the hoistway wiring for the lobby displays.
  • the same is true for the associated, standard, remote station link (RSL) wires. (Note Fig. 7 .)
  • the display functions of the exemplary embodiment include: a car direction indicator preferably in the form of an isosceles triangle-like graphical figure, the apex of which is pointed in the direction of car travel, viz . " ⁇ " for the "up” direction and “ “ for the "down” direction (note right-hand portions of Figs. 1A, 1B, 1D & 1E and 2-5 ), which triangle preferably is animated (blinks "on” and "off” in rapid succession); a car position or floor indicator preferably in the form of a numerical display (e.g ., "44" for the forty-fourth floor; note Figs.
  • F refers to a fixed display, viz . a represen­tation of information that is "called up” by a source, and its composition and location on the display cannot be altered
  • FV refers to a display with a variable parame­ter, viz . a representation of information that requires additional information from the source which "calls it up", and the composition and location of the information on the display cannot be altered
  • FV refers to customer specified information, viz . the customer (e.g. , the building owner) is free to set up custom information and has some limited flexibility as to where the information is to be displayed, when and how.
  • the "priority" of the display fixture function refers to its ranking or relative position of importance in the display.
  • the interface board since the interface board is listening to both the RSL (remote serial link) and the RS422/485 communication line, the interface board must know which information is first (second, etc. ) to get update attention for its portion of the display.
  • the ELD interface board is preferably configurable as either a car display or a lobby display.
  • the elevator related information is displayed in the top or upper portion of the screen (location areas A & B of Figure 6A ), while the building related information is displayed in the bottom or lower portion of the screen (location areas C & D of Figure 6A ).
  • the ELD accepts an assortment of command blocks from the elevator management or monitoring system (EMS) via an RS422/485 link. These commands cause the ELD to implement displays, including, if desired, channeling ( Fig. 1C ) and directories ( Fig. 5 ).
  • EMS elevator management or monitoring system
  • the ELD upon detecting no EMS activity, implements a default display from the remote station link (RSL) data, including at least the car position and direction.
  • RSS remote station link
  • the ELD receives the following data from the RSL:
  • Position information obtained from the standard "PIDATA” and “PICLOCK” outputs of the standard RSL station [an “Industrial Control Unit” (ICU) based decoder for the RSL communications protocol]. It can be encoded as, for example, two sixteen-segment light emitting diode (LED) type characters. As has been previously established, the decoded position value points to a table containing reconfigurable floor labels.
  • Direction information which causes the up or down triangular "arrow” to be displayed on the default display ( Figs. D & E , with the latter used if the installa­tion does not include an EMS or its equivalent).
  • Hall lantern which causes the large direction indicator to be displayed ( Fig. 1F ; hall only).
  • Channelling which provides the command and data to display channelling ( e.g. , Fig. 1C .
  • All jewel messages are preferably stored as ASCII (American Standard Code for Information Interchange) characters preferably in an interchangeable PROM. If it is necessary to change the language of the jewels, the PROM thus easily can be replaced with a PROM of the desired language.
  • ASCII American Standard Code for Information Interchange
  • the ELD upon initialization, supports display of the default display and jewels without requiring any downloaded configuration information.
  • the ELD interface PCB assembly is the component of the ELD system which creates the displays, drives the EL glass, and coordinates communication with the elevator's central processor [the "Operational Control Sub-System” (OCSS)] and the elevator management or monitoring system (EMS).
  • OCSS Operaational Control Sub-System
  • EMS elevator management or monitoring system
  • Figure 7 provides a block diagram of the ELD system and shows the location of the ELD interface board in the standard elevator system architecture.
  • the ELD interface board is a microprocessor based computer board.
  • the computer runs the firmware which creates the graphic displays for the EL glass.
  • the firmware also interprets communication with the EMS processor and the elevator's central processor (“OCSS"), herein termed the "main processor” to distinguish it from all the various central processor units (CPUs) used in the various boards and subsystems for the elevator.
  • OCSS central processor
  • Hardware termination of the EMS communication resides on the ELD interface board. Communication from the "OCSS” is decoded on the ELD remote station (RS) interface board. The decoded information is sent to the ELD interface board through connectors that also serve to anchor the remote station interface board in a "piggy back" fashion to the ELD interface board, with appropriate standoffs also being used .
  • RS remote station
  • Dedicated video circuitry converts activity from the board's central processor to the signals necessary to drive the ELD. Signals and power are fed directly from the board to an ELD located up to, for example, 12"(300mm) from the board's connector. Another set of signals and power are available for use to the video transmitter board (VTB), which is responsible for sending these signals over a distance of up to, for example, 25 feet (7.62m) to the video receiver board (VRB).
  • VTB video transmitter board
  • VRB video receiver board
  • FIG. 8 A block diagram of the circuit is shown in Figure 8 .
  • the following sections are a detailed description of the circuitry of the ELD interface board.
  • the processing unit for the ELD interface board can be, for example, an "80188" microprocessor.
  • the 80188 microprocessor is an eight (8) bit (DATA bus) controller, which can address up to a megabyte (1 MB) of contiguous program/data memory and sixty-four (64 KB) kilobytes of input/output (I/O).
  • a KB (kilobyte) refers to 210 x 8 bits (8 bits used for processing in parallel is called a byte).
  • the 80188 has many functions embedded within the integrated circuit (IC). A further description of the 80188 device is found in the 16-Bit Embedded Controller Handbook (INTEL Corp., Santa Clara, CA; 1989; particularly pp. 9-151 - 9-207).
  • the highlights of the device which affect the design of the ELD interface board are as follows: o an internal oscillator circuit, which runs the central processing unit (CPU) at one-half (1 ⁇ 2) the speed of the crystal presented at its crystal input pins; o a RESET pin which puts the CPU in a known state; o a multiplexed DATA/ADDRESS bus. o pins to accomplish data/program memory space decoding; o pins to accomplish I/O space decoding; and o an internal prioritized interrupt structure.
  • CPU central processing unit
  • the ELD interface board may have, for example, a "14.31818 MHz" crystal to run the 80188.
  • the 80188 has internal clock generating circuitry, and the maximum speed which the 80188 can run according to its specifications is eight megahertz (8 MHz).
  • a slightly slower than maximum speed may be chosen (e.g. 7.15909 MHz), to accommodate slower, less expensive memories.
  • the "RESET” circuit exists to ensure that the processor powers up in the correct sequence. Upon power up, the capacitor C12 holds the “/RES" pin to the CPU “LOW” for approximately one hundred (100 ms) milliseconds. This allows the CPU to receive more than the minimum amount of clock pulses in a "RESET” state, such that the execution of code at a known location can begin.
  • a "WATCHDOG” in the "RESET” circuitry guards the proper operation of firmware.
  • the multi-vibrator U11A is triggered, when it is released from a "CLEAR” state (output /1Q HIGH), after the power up “RESET” sequence.
  • the multi-vibrator begins to "time out”. A two hundred and fifty (250 ms) millisecond pulse will go “HIGH” unless its trigger pin 1B detects a rising edge (thus causing a "re-trigger”).
  • the positive going edge is provided by the CPU pin /PCS0 .
  • U11A If /PCS0 is not pulsed, the two hundred and fifty (250 ms) millisecond pulse of U11A is released and provides a positive going trigger to the multi-vibrator U11B .
  • U11B is armed to provide a twenty-eight (28 ⁇ s) microsecond pulse to the /RES pin of the CPU, which will properly set the CPU into its "RESET” state.
  • U11A is then re-triggered, and the process has the potential to reoccur. This operation ensures that the software will not run out of control, since it will regularly update the "WATCHDOG" when running properly.
  • the CPU can halt its own operation by addressing the "WATCHDOG” by its /PCS5 pin. This over-rides the normal operation of the multi-vibrator by causing /RES to go “LOW” and clearing U11A . This causes a "LOW” to "HIGH” transition on the output /1Q , which triggers U11B (same as allowing U11A to "time out”).
  • a push button SW1 is provided to allow a manual “RESET.” Its operation is similar to the "POWER UP” sequence, since actuating the switch drains the capacitor C12 .
  • the "RESET” circuitry also consists of a "LOW VOLTAGE DETECTOR.” If the power voltage Vcc (nominally +5 volts) drops below +4.68 volts (as measured by the compara­tor U10A ), the circuitry will "RESET” the processor until the voltage has risen above +4.77 volts.
  • Latches U32 , U37 , and U41 are used decode the time multiplexed "ADDRESS" bus.
  • Transceiver U38 buffers the "DATA BUS" to the program/data memory from the communi­cation to the video storage and display device ( VSDD ) U31 , which also resides in program/data memory space.
  • Trans­ceiver U35 buffers the "DATA BUS” to the RSL interface board.
  • U34 buffers the "DATA BUS" to the UART. Both RSL and UART communication buffers reside in I/O space.
  • the 80188 can address up to 1 MB of program/data memory.
  • Six memory chip select pins ( /UCS , /LCS , and /MCS0-3 ) are provided to facilitate memory address decoding.
  • the largest memory space decoded by the pins /MCS0-3 is 64 KB. Because preferably some larger memory chips are used, U42 is used in conjunction with the 80188 chip selects to encode selects directly from the "ADDRESS BUS.”
  • the board contains three 128 KB (393,216 bytes) electrically programmable read-only-memory (EPROMs) for program and fixed data memory - one 32 KB (32,768 bytes) static random-access-memory (SRAM) for variable data entry and one 8 KB (8192 bytes) SRAM for scratchpad.
  • EPROMs electrically programmable read-only-memory
  • SRAM static random-access-memory
  • the computer's memory also maps into a 64 KB (65,536 bytes) space for communications to the video storage and display device.
  • Figure 9 shows the address space of these memories and the origin of each chip select.
  • the 80188 can address up to 64 KB of I/O space.
  • Six peripheral "chip" select pins ( /PCS0-5 ) are provided to facilitate I/O address space decoding.
  • I/O space is used for RSL communication via the ELD remote station interface board, for the UART communication port, for the programmable peripheral interface, for re­triggering the "WATCHDOG” timer, and for causing an automatic "RESET” from the WATCHDOG.
  • Figure 10 illustrates the locations in I/O space for these functions.
  • the programmable peripheral interface U14 allows three bytes worth of information to be manipulated by the CPU and used for peripheral functions.
  • the "PORT A” of this device is used as “INPUT” to read the configuration of SW2 (note Fig. 8 ).
  • "PORT B ⁇ is also “INPUT” to read the configuration of SW3 .
  • "PORT C” is used as "OUTPUT.”
  • the three most significant bits (MSBs) are used to govern the status of LED1 , LED2 , LED4 and LED5 of Fig. 8 .
  • the second LSB (least significant bit) is used to provide a "STATUS" bit to indicate a failure on board to the ELD RS interface board, as explained more fully below.
  • the LSB of the peripheral interface is used to provide an inverted screen display, also as explained more fully below.
  • the elevator management or monitoring system communicates to the ELD interface board by, for example, two shielded twisted "24 AWG" pairs.
  • the signals are standard half duplex RS485/422 +5 volts differential, one pair for transmission signals to the ELD and one pair for reception of signals from the ELD.
  • the pairs are terminated at the ELD interface board at connector J8 .
  • Discrete protection and filtering elements are self explanatory.
  • the termination resistor R17 for the differential receiver is jumped in by jumper JMP3 only if it is the final device in a string of receiv­ers.
  • the differential signals from the EMS are received by a dual differential receiver U46 and converted to a single ended signal.
  • the serial stream is provided to the UART U33 , which translates the data to a byte readable for the CPU.
  • parallel data written to the UART from the microprocessor is converted to a serial stream by the UART and sent out via the differential driver U50 .
  • the communication may be carried out at 9600 BAUD.
  • the counter U49A uses the 4.9152 MHz oscillator as its input.
  • the second MSB yields a frequency of 64 X 9600 Hz (614.4 MHz or 4.1952/8 MHz), which is used by the UART to decode the serial signal.
  • a jumper JMP1 is available to tap off the MSB of U49A , if such is desired.
  • the RSL signals from the elevator are transmitted by two wires carrying +30 volts, COM, and two wires carrying information synchronous to a clock patterned data frame.
  • a five bit data "frame" can be transmitted to or received from up to, for example, sixty-four (64) stations.
  • the sequence consists of sixty-four (64) transmit frames followed by sixty-four (64) receive frames.
  • the first four (4) frames contain special information, as does the fifth bit of the first thirty-two (32) frames.
  • the RSL wires are terminated at the ELD remote station interface board.
  • This board connects in a "piggy back" fashion to the ELD interface board via connectors J1 and J2 .
  • Connector J1 contains control signals necessary to address ( /PCS1 ), be interrupted by, read from, and write to the RSL interface board. These signals are separated by a buffer U40 .
  • Connector J2 passes the eight (8) bit "DATA BUS” and the seven LSBs of the "ADDRESS BUS" to the ELD remote station interface board.
  • the "DATA BUS” is buffered by transceiver U35 , and the "ADDRESS BUS” is separated by the buffer U36 .
  • the ELD RS interface board contains eight (8) bytes of information for the ELD interface board. With seven (7) address bits, one hundred and twenty-eight (128) addressable locations are possible, allowing for other, supplemental uses.
  • the interrupts which affect the software operation of the CPU are controlled by input pins directly at the 80188.
  • the CPU provides three interrupt pins ("INT0 - INT3"), which are prioritized by software initialization of the CPU.
  • the method of interrupt of the pins is also programmable to be HIGH, LOW, LOW-to-HIGH, or HIGH-to-LOW. A description of these interrupts and their origins is provided in Figure 11 .
  • INTO is derived from the UART and EMS COMMUNICATION port.
  • the processor is only to be interrupted when the ELD is properly addressed. Each ELD is given a unique address.
  • the protocol further defines that a "DLE” signal (10H) will precede the address byte.
  • the EMS COMMUNICATION hardware uses the “DLE” to "wake up” the UART RCV CHAR (received character) interrupt circuit.
  • the signal as received by the UART U48 causes the "RXRDY" pin to go “HIGH.” This signal triggers the multi-vibrator U53A , causing 1Q to create a one hundred and eighty-one (181 ns) nanosecond positive (+) pulse.
  • INT1 for the CPU is simply the vertical sync (VS) to the ELD. This provides some critical timing to the software of the board.
  • INT2 is received from the UART when a byte, which has been sent to the UART for transmittal by the CPU, is finished being processed.
  • INT3 is sent by the remote station interface board when the RSL has completed a communication cycle.
  • VSDD video storage and display device
  • VSDD provides a sixty-four (64) KB window for the CPU on the two hundred and fifty-six (256) Kwords (512 KB) of memory which it manages; o the VSDD has an external clock and can insert "WAIT" states on the CPU access cycles to the VSDD; o the CPU has access to a control block in the VSDD (this control block allows the CPU to set up the video timing and video memory management parameter); o DRAM (dynamic memory) is used for video memory; and o video signals provided by the VSDD are cathode ray tube (CRT) compatible and are based upon an external video clock frequency.
  • CTR cathode ray tube
  • the VSDD is connected directly to the CPU multi­plexed "ADDRESS/DATA BUS.”
  • the address latch signal "ALE" is provided such that the busses are de-multiplexed internally. Sixteen bits of address are used. Hence, a sixty-four (64) KB window is provided to the CPU.
  • the pin A16 of the VSDD is used by the CPU to select the device which resides in its memory space, as explained above with respect to Figure 9 .
  • VSDD memory locations Sixteen, word wide VSDD memory locations are programmed by the CPU to begin proper operation of the device. These registers are explained in detail in Microprocessor and Peripheral Handbook, Vol. II , supra . Among the parameters which affect the hardware are the type of DRAM used (e.g. , 64 K X 4 bits), the video signals format (e.g. , non-interlaced, digital signals), the horizontal and vertical sync timing generation parameters, and the video clock basis (e.g. , an external oscillator U30 , 12 MHz).
  • the VSDD is constantly refreshing the DRAM and sending out the proper video signals.
  • An oscillator U29 of, for example, ten (10) MHz is used to control internal VSDD task timing. (The VSDD generally will not operate properly under 10MHz due to the time required to set up and display objects on the screen.)
  • the VSDD allows communication with the CPU. If communication can not be serviced, the VSDD can "hold” the CPU by inserting a "WAIT” state (extending the read or write cycle), until the VSDD is no longer busy.
  • the DRAM refresh task is handled by the VSDD, which uses its 10 MHz task clock and the CPU programmed parame­ters to accomplish the refresh function.
  • the D-latch U23A and the multiplexers of U9 are used to decode the refresh signals to the memories.
  • Video signals emitting from the VSDD are in a format suitable to run a cathode ray tube (CRT).
  • CRT cathode ray tube
  • An electrolumin­escent display requires slightly different timing. The signals are therefore conditioned by combinational logic to yield the correct timing.
  • a contrast of the CRT signals versus the ELD signals is graphically shown in Figure 12 .
  • the video clock signal “CLOCK” (the output of the 12 MHz oscillator U30 ) is passed through two inverters ( U54A & U54B ), before being sent to the ELD glass connec­tor J5 as “VCLK.” This provides enough delay so that the video signal “VID” will be valid at the rising edge of the "VCLK.” It should be noted that “VID” is derived from the “VIDEO” directly out of the VSDD. The “VIDEO” is sent through an “EX-OR” gate with the CPU generated signal “INV” which allows the "VIDEO” signals to be inverted if the "INV” signal is set “LOW.”
  • the lower significant bits of the preloadable counter U59 are manually programmable. This is because the specifications of the VSDD show that there may be a clock pulse delay from the assertion of the "HSYNC" signal from where it is expected in the video cycle time frame.
  • VSYNC from the VSDD triggers the counter U56 to count down from three (3). On the fourth "HS” pulse detected, the first line of one complete frame will be valid. Thus, the video sync (VS) is derived for the ELD.
  • Raw video signals (HSYNC, VSYNC, and CLOCK) are boosted by the buffer U60 and sent to the connector J6 .
  • the signal VID is also buffered and sent to J6 .
  • This connector allows the video to be sent to the video trans­mitter board (VTB), which can process the signals and send them over, for example, twenty-five (25) feet to a remote glass in the elevator cab to a video receiver board (VRB), as generally illustrated in Figure 7 , which board prefera­bly is mounted on the back of the remote EL screen.
  • VTB video trans­mitter board
  • VRB video receiver board
  • this remote glass will show the same informa­tion as the glass connected directly to the ELD interface board.
  • the ELD interface board preferably is packaged in a unit along with the ELD remote station interface board, which mounts piggy-back to the ELD interface board via connectors J1 and J2 , as generally shown in Figure 15 . Appropriate standoffs are added to give further support.
  • the ELD interface board When the ELD interface board is used as a hall display, it is mounted in the wall with the glass prefera­bly being the only visible portion of the entire ELD system which can be seen by the passengers.
  • the glass and boards preferably are packaged in a steel box with the chime speaker, as illustrated in Figure 15 .

  • This connector accommodates, for example, "14 AWG" wire from the power supply that is either mounted at the top of the cab, or inside the hoistway. No local regula­tion of the power is required, but filtering of the +5 volts is provided by capacitor C65 .
  • the +5 volts is used by the ELD interface board for its logic functions.
  • +5 volts is sent to the connector J6 for use by the video transmitter board logic.
  • Both +5 volts and +12 volts are sent to the connector J5 for use by the EL display and to connector J7 for use by the video receiver board (VRB), which may be located up to twenty-five (25) feet from the ELD interface board.
  • VRB video receiver board
  • the ELD interface board typically will be tested and assembled at the factory in its final configuration for the field site.
  • DIP switch SW2 controls various test and indication parameters. The functions and final settings are:
  • DIP switch SW3 contains configuration parameters. Specifically, the settings are as follows:
  • Initial adjustment requires setting DIP switch SW4 such that the correct timing of the horizontal video is set on the screen. Initially, the setting should be at "10100111".
  • Jumper JMP1 should be in position "1" and "2", and jumper JMP2 should be installed.
  • the ELD of the present invention allows for the use of a single hardware system with built-in flexibil­ity that allows the same basic hardware to be used for basically any elevator application.
  • LED3 (green) is provided to indicate that the processor is running and is not in a "RESET” state.
  • LED1 , LED2 , LED4 and LED5 (red) are used by the software to show that the CPU is executing various functions, the operation of which has been explained supra . Using these LEDs, a field mechanic can determine whether any problems are originating from the ELD interface board, the RS interface board, or such things as the power coming into the board.
  • Production test features of the ELD interface board are embedded within the CPU for internal self-testing at power up. DIP switches are provided to further guide the software to determine what test mode is desired. Produc­ tion testing can consist of providing signals to the connectors which allow the ELD interface board to communi­cate with the ELD RS interface board and the EMS (RS485/422).
