Definitions

  • the aforementioned invention relates to a circuit device with a line matrix for signal transmission in elevator systems, in which peripheral signal devices connected to the points of intersection between row conductors and column conductors can be connected to central signal processing.
  • Such arrangements are used in elevator systems as a transmission device for data acquisition by the elevator controller for e.g. Cabin and floor calls as well as for call acknowledgment and signaling in the cabin and on the floors.
  • the invention is based on the knowledge that the electronics and installation effort for the connection of signal sources and signal sinks can be greatly reduced with a matrix-shaped conductor arrangement. For example, when using an 8 x 8 matrix with only 16 control channels for the 8 column and row conductors, 64 crossing points are selectively controlled. But also in the optical representation of information, savings in electronics and connecting lines have been achieved with matrix-shaped, partially orthogonal conductor arrangements. It was therefore obvious to make use of the matrix concept, particularly in elevator systems, in which the expenditure for the electronics, the installation and the space requirement is essentially determined by the logic inputs and the signaling.
  • matrix-shaped conductor arrangements are known with which the position indicators in the car and the indicator lamps on the floors are controlled in elevator systems.
  • the indicator lamps for the individual floors are arranged at the intersection points of a matrix, the rows and columns of which are each connected to a driver which is selectively acted upon by the corresponding position or information signal.
  • Each row conductor is preferably assigned a specific floor group of a building and each column conductor a specific floor within a group.
  • a disadvantage of this circuit arrangement is the fact that it is only suitable for unidirectional signal transmission from the elevator control to the car or to the floors. For signal transmission in the opposite direction as e.g.
  • the object of the invention is to provide a signal transmission device which connects peripheral signal transmitters and peripheral signal receivers to a central signal processing device in elevator systems and greatly reduces the electronics and installation outlay required for this in comparison with known devices of this type. Furthermore, the signal transmission device according to the invention should be fully compatible with standardized circuits of modern information systems.
  • a first advantage targeted by the invention is based on the functional double utilization of the line matrix. Since common row conductors are used to detect the peripheral signal transmitters and to control the peripheral signal receivers, a group of row conductors can be saved compared to conventional devices with the same function and thus also their control electronics and their connecting lines to the tail unit and signal processing. The effort already reduced by using a matrix arrangement is thus further reduced by the functional double use of the row conductors. Further advantages result from the fact that, due to the cyclical activation of the row conductors and the time-multiplexed utilization of the column conductors, there is a clocked system which detects or controls the connected signal transmitters and signal receivers in pulse mode.
  • the elements connected at the crossing points of the row and column conductors e.g. Switches for call input or opto-electronic display elements for signaling can therefore be detected or controlled individually or in any number at the same time.
  • the line matrix built and operated according to the invention therefore has a significantly increased information transmission capacity. It has also proven to be advantageous that, due to the clocked operation of the row and column conductors, the functions assigned to their crossing points are activated with the same frequency - within the row conductors simultaneously, between the row conductors with a constant phase position.
  • Fig. 1, 1 denotes an elevator shaft, only partially shown, in which an elevator car 2 is guided.
  • T, to T 32 are shaft doors arranged on the floors.
  • a circuit arrangement 6 for bidirectional signal transmission between peripheral signal devices 12, 13 in the elevator car 2 or on the floors Sti - St 32 and a central signal processing 5 in the elevator control 7 is placed in the elevator car 2 and on a middle floor, for example St 16 , a circuit arrangement 6 according to the invention. Both connections are set up analogously.
  • Pushbutton switches 12.1 for the car calls and limit switches 12.2 for the door operator and load floor are provided as signal transmitters 12, while the signal receivers 13 are designed as opto-electronic display elements 13.1 for signaling or as electro-acoustic signaling devices such as gongs 13.2.
  • the line matrix 8 with the interface 9 is connected to a microprocessor 10 and is connected to the central signal processing 5 via a serial interface 14 and a two-wire line 38 in the hanging cable 11.
  • the line matrix 8 contains eight column conductors So - S 7 for signal transmission from the peripheral signal transmitters 12 to the microprocessor 10, eight column conductors S 8 - S 15 for the signal transmission in the opposite direction from the microprocessor 10 to the signal receivers 13 and eight row conductors Zo - Z 7 for establishing the connection via the column conductors S.
  • the row conductors Z o - Z 7 are two groups of column conductors S 0 - S 7 and S 8 - S 15 assigned and thus also the two transmission facilities together. Functionally, they are used twice.
  • the line matrix 8 is shown in the form of orthogonally crossing row conductors Z and column conductors S. In the present case, however, no such requirements are placed on the geometry of the line matrix 8, which in practice can be designed as conductor tracks on a printed circuit board or as wiring on a terminal strip.
  • the row conductors Z o - Z 7 are each assigned a row control 16, while the column conductors S 0 - S 7 and S 8 - S 15 each have a column control 17 and a column control 18, respectively.
  • the line driver 16 contains a transistor 19 connected as an active 0 driver per line, which is connected to the collector or emitter, in a known manner, with the row conductor or ground assigned to it. Its base is connected to an optocoupler 20 consisting of an IR or light-emitting diode 20.1 and a phototransistor 20.2, which connects to the microprocessor 10.
  • the column control 17 the column conductors S o - S 7 are each signal-wise connected to the memory cells 25 combined to form a buffer via an optocoupler 21, consisting of an IR or light-emitting diode 21.1 connected to the positive pole and a phototransistor 21.2.
  • the column driver 18 contains for each column conductor S 8 - S 15 a transistor 28 connected as an active 1 driver, which is connected to a positive pole or a column conductor at the collector or emitter.
  • the optocouplers 22 are constructed in accordance with row control 16 and lead the outputs of the memory cells 29 to the inputs of the active 1 drivers 28.
  • the peripheral signal transmitters 12 are each connected via a two-wire line 31 and a blocking diode 32 to the crossing points 36 of the row conductors Z o - Z 7 with the column conductors S o - S 7 , while the peripheral signal receivers 13 are also connected to the crossing points 37 of the row conductors Zo - Z ⁇ are connected to the column conductors S 8 -S 15 .
  • blocking diodes 32 are required in order to prevent feedback and the resulting malfunction of other devices.
  • the blocking diodes 32 are polarized so that the current can flow from the column conductors S via the signal transmitters 12 or signal receivers 13 to the row conductors Z.
  • Push-button switches 12.1 for the call input and limit switches 12.2 for the door drive and load floor are connected as peripheral signal transmitters 12 in the elevator car 2.
  • a maximum of 64 peripheral signal generators 12 can be connected to the intersection points 36 of the 8 ⁇ 8 matrix provided.
  • the peripheral signal receivers 13 in the elevator car 2 consist primarily of opto-electronic display elements 13.1 for the position display and the call acknowledgment.
  • a maximum of 64 peripheral signal receivers 13 can be controlled at the intersection points 37 with the provided 8 x 8 matrix.
  • the row and column conductors Z and S are connected via the interface 9 to a control unit 34 for the matrix control and an information concentrator 35 for the signals.
  • Control units 34, such as information concentrator 35 are designed as part of a microprocessor 10, which is arranged in elevator car 2 and is connected in a known manner to the elevator control system via bidirectional signal transmission via serial interface 14 and hanging cable 1.
  • the signal for activating the transistor 28 comes from the central signal processing 5, from where it was read into the associated memory cell 29 via the hanging cable 11, the serial interface 14 and the microprocessor 10, and via the optocoupler 22 the active-1 driver transistor 28 to control. Since the peripheral signal devices 12, 13 are driven line by line by the line matrix 8 in clocked operation, a pulsed excitation current results for the opto-electronic display element 13.1 at the crossing point Z 4 S 15 .
  • the pulse frequency f 1 and the pulse duty factor T of the cyclic scanning are therefore selected so that a permanent light of sufficient intensity is perceived by the eye. Instead of the one crossing point Z 4 S 15 , it is also possible to operate all crossing points 37 of the 8 x 8 matrix in this way.
  • the 64 connected opto-electronic display elements 13.1 then emit continuous light at the same time. But simultaneous activity of all connected signal devices 12 and 13 is possible not only within the intersection points 36 and the intersection points 37. Since the row conductors Z 0 -Z 7 are common to both groups of column conductors S 0 -S 7 and S 8 - S 15 , all the signal transmitters 12 and signal receivers 13 assigned to a row conductor are detected or controlled simultaneously. If the full transmission capacity of the 8 x 26 line matrix 8 is used, 64 call transmitters and limit switches 12.2 at the intersection points 36 and 64 optoelectronic display elements 13.1 at the intersection points 37 are connected to the central signal processing 5 in the elevator control 7 at the same time.
  • the line matrix 8 can also optionally be equipped with a different number of row conductors and column conductors. This makes it possible to optimally adapt the circuit arrangement according to the invention to the needs of a specific elevator installation and to provide as many transmission channels in the two transmission directions as are actually required.
