  • One by one The hole in the carrier film formed is always to the left of the starting position of the carrier film formed by the poster 1.
  • the service position of the carrier film should also be identified by a metal film in the form of a Bero marker, and, as sketched in FIG. 4, not offset in the center but to the left, so that when changing tubes there is no need to use this Bero marker in manual mode to run over.
  • the controller After closing the door of the removable poster showcase, the controller first moves to the starting position in order to achieve a tie between the internal poster counter and the actual poster stand. The selected program is then executed. This process, known as poster synchronization, takes place after every door closing, after a power failure and after a watchdog reset.
  • the changeable poster showcase program In order to synchronize posters, the changeable poster showcase program generally rewinds the carrier film to the right until the upper contactless proximity switch has recognized the starting position. If, after manually opening the service opening, the operator forgets to manually move back to the start position before closing the door of the removable poster display case, no start position would be recognized without additional markers during the poster synchronization. The billboard was then moved to the right until it stopped. This may result in a film tear if the runtime monitoring does not stop the engine beforehand. Proper automatic operation would be impossible in any case.
  • the hardware is designed in such a way that the use of non-contact switches in PNP or NPN design is possible via an assembly variant.
  • the change of display cabinet firmware finds out the actual switching direction via a port input of the microcontroller (DIP switch).
  • the control unit already shown in FIG. 3 is mounted on a mechanical device 14 in the form of an L plate in the lower part of the billboard display case.
  • the main board 15 is spaced 16 parallel to the long leg of the L-plate.
  • the connectors provided with the reader 19 are at a 90 degree angle to the main board 15 and protrude through corresponding holes in the short leg of the L-plate.
  • the circuit board 15 with the electronic components and the connectors is mounted with the component side up on the L-plate. After loosening the fastening screws, the L-plate with the mounted board 15 can be pulled out of the removable poster showcase like a drawer.
  • the component side of the circuit board 15 is at the top, so that cables can be connected without problems. In addition, 15 measurements are possible even with the circuit board installed.
  • control unit In addition to the connectors mounted on the board 15, the control unit also contains additional, separately connected Control elements, namely the buttons 8, 13, 9 for scrolling to the left and scrolling to the right, and a door switch.
  • buttons are connected to the board 15 via wires and Phoenix connectors.
  • the buttons have the following functions:
  • the door switch switches the removable poster showcase to automatic mode when the door is closed and to manual mode when the door is open.
  • buttons for scrolling to the right or left are only in manual mode, i.e. with the door open, effective.
  • manual mode the winding process stops when the button is pressed continuously when one of the two end positions is reached.
  • the service position e.g. for a tube change, can only be achieved if the left hand button is released after the stop in the start position and pressed again.
  • the change of the display case can be programmed either by serial data transmission via a connected laptop (RS232), by reading a chip card or by data transmission via a modem.
  • connection option is provided which can be combined with a suitable modern.
  • Non-multiplexed status signals (such as DTR) then ensure that the RxD / TxD lines are switched accordingly.
  • the changeable poster showcase software allows free programmability of the poster display times, the assignment of posters to groups and the date / time-controlled selection of sequence processes.
  • a group can of course include all 16 posters.
  • the posters are rewound and rewound within a group, with the rewinding process being interrupted for a definable showing time for each poster.
  • the sequence consists of only one poster.
  • a still image is defined in this way. In this case, since no winding process is necessary within the sequence, there is no need to specify a display time for the still picture.
  • the display time for the still picture is then identical to the sequence length defined in a daily schedule.
  • the defined posters run forwards and backwards within a sequence, thus 7-8 - 9 - 10 - 11 - 10 - 9 - 8 - 7 - 8 - 9 - 10 etc. in the example explained above.
  • a daily schedule for the operation of the billboard display cases is programmed by assigning individual sequences to times during a certain day.
  • a specific lighting status of the removable poster display case can be programmed.
  • a campaign can be programmed from several daily schedules by assigning the daily schedules to a specific calendar week, whereby optionally up to four date-related calendar days can be carried out.
  • the sequences, the daily plans and the campaign are defined using a Windows 3.1 program. Attention was paid to functionality and ease of use. Furthermore the inputs checked for plausibility.
  • a C ++ compiler serves as the programming language.
  • a daily schedule file always contains a list with the names of the assigned sequence files, a campaign file, as well as always a list with the names of the assigned daily schedule files.
  • the assignment is strictly bottom-up, ie the sequences must first have been defined before a day plan can be defined, and daily plans must be set up before the campaign can be defined.
  • the assignment via file names in list fields presupposes the existence of the files used, since only existing files are listed for selection.
  • the files remain independent of each other from the operating system perspective, so they can be renamed or deleted with the Windows File Manager. A programmed assignment can become invalid in this way if the user does not take the necessary care.
  • a serial interface in accordance with the RS485 standard is provided for the syrichronization of several billboard display cases belonging to a device arrangement, which each billboard device has. Since the microcontroller used only has one UART interface, this is multiplexed, the UART interface being connected to the laptop interface when the removable display case door is open and to the RS485 serial synchronization interface when the removable display case door is closed.

  • only the removable poster showcase which acts as the master device, needs to be programmed.
  • the other billboard displays that function as slave devices then only receive commands of the form from the billboard showcase that functions as master devices Fast forward a poster or Rewind a poster .
  • a BCD coding switch setting not equal to zero switches the relevant billboard display hardware to the slave operating state.
  • the L-plate 14 To operate the BCD coding switch, the L-plate 14 must be pulled out of the interchangeable poster showcase, since the BCD coding switch is on the board 15. However, the switch position can be queried from the outside via the laptop.
  • An 80C592 microcontroller is used as the computer core. This has an internal RAM with 512 bytes.
  • a Dallas module DS1642 is used as memory for the billboard program and for the real-time clock. This block contains a RAM with 2KByte, a real time clock, a lithium battery with a lifespan of approx. 10 years and a voltage monitoring circuit.

  • the power supply consists of a line filter, a transformer, rectifiers and voltage regulators.
  • the transformer can be switched to 110 V operation via solder bridges. There is no mains fuse because the transformer has a thermal fuse that becomes high-resistance in the event of a short circuit or thermal overload.
  • the transformer has a 30% reserve, which enables safe operation even at 70 degrees Celsius.
  • the BCD coding switch determines the address of the connected billboard showcases in a chain in the course of the billboard display synchronization.
  • the data transmission between the master device and the slave devices takes place via a serial point-to-point connection according to the RS485 standard, whereby no star-shaped wiring is provided.
  • Switch position 0 of the BCD coding switch defines the removable poster showcase as the master device.
  • the changeable poster showcase will then supply all connected slave devices with commands to fast forward and rewind.
  • the BCD coding switch defines the corresponding billboard display as a slave device.
  • the billboard display case prepared in this way does not need to be programmed; it receives all commands from the billboard display cabinet that functions as the master device.
  • Each slave address may only be assigned once within the chain-shaped device arrangement. In the Domino mode, the slave devices of the chain-like device arrangement must also receive ascending addresses as seen from the master device.
  • the changeable poster showcase reaches an error state that can only be exited by the conscious acknowledgment by an operator.
  • a special sound signal that is only generated in this case and is designed as an intermittent beep with a frequency of approximately 4 Hz.
  • the error signal is only generated when the door is open. If the door is closed without the error being acknowledged, the signal is switched off but is generated again the next time the door is opened.
  • the error must be acknowledged by pressing both manual buttons 9 at the same time.
  • the changeable poster showcase is then again in the normal operating state, that is, in the manual operating mode when the door is open.
  • the sounder generates a single short beep as an OK message in the following operating states: after the power-on process, after successful transmission of the date / time via the serial interface, after successful transmission of the program via the serial interface, after successful reading of a program from a chip card, after successfully writing data to a chip card.
