Definitions

  • the invention relates to a control device for doors that can be actuated from a remote control station by means of opening and closing signals, auxiliary power-operated doors, in particular rail vehicles that can be coupled to trains, each door being an opening element that can be actuated manually or automatically when a person approaches, such as a door handle or -grip or an electrical or electromechanical unlocking device and a pinch protection designed as a reversing device.
  • Pneumatic door controls of the type mentioned above are known in particular for passenger coaches and multiple unit trains, which have the following properties: the driver of the locomotive or the driver issues an opening signal for the pneumatic door actuation on the respective entry side from the driver's cab via a switch.
  • This signal excites electromagnetic valves, which in turn influence single- or double-acting cylinders in the opening direction, whereby the following conditions usually have to be met beforehand: -
  • a speed monitor must register when the speed drops below a certain speed of approx. 2 to 5 km / h and only then is the signal given by the switch activated or the lock for the closed doors released; - The passengers must operate a door handle to release the opening process.
  • the driver is informed of the closing status of all doors by an indicator lamp which can be switched by entry-specific limit switches on the doors, whereupon he can safely initiate the starting process.
  • an opened door can be closed automatically or arbitrarily, the closing process being interruptable by any number of reversals, and -
  • the closing signal When the closing signal is present, an open door is closed, the closing process being interruptible by a maximum of a predetermined number of reversals and / or only for a certain period of time from the start of the closing signal, after the predetermined number and / or after the specific period of time has elapsed, the reversing device switched off and the subsequent closing process is carried out without interruption.
  • each door has a switching device switched only when the door is open
  • the control device The door only opens for a predetermined, first period of time when the opening signal is present and serves as a door release signal, and the opening element is actuated.
  • the first period begins again and closes again automatically after the first period , and - if a closing signal is present - locked a closed door, - an open, unused door closes and locks, holds an opened, used door open for a predetermined, second period of time and then initiates a closing process, -
  • the closing movement is reversed for a predetermined, third period of time and then initiates a new closing process.
  • the drawing shows an embodiment for a control device designed according to the invention.
  • a signal line 1 for a door release or opening signal, a signal line 2 for a closing request or closing signal and a signaling line 3 run through the whole train.
  • a signal must be fed in alternately from the driver's cab into one of the signal lines 1 or 2.
  • the signal line 3 leads to an indicator light in the driver's cab, which goes out in the closed state of all the doors; if necessary, a starting lock can also be provided, which enables the signal line in the signal line 3 to be started only when all doors are closed.
  • a control device of the type described below is assigned to each door.
  • the control device can be subdivided into a function block 4 for the closing or reversing and a function block 5 for the forced closing.
  • the doors are also provided with a manually operated opening element (not shown), in particular a door handle or handle, or an electrical or electromechanical unlocking device which is used to unlock the closed door or to start the opening process when the opening signal is present in the signal line 1 is operate.
  • the function block 4 for closing or reversing has a two-pole switch 6, which is only open when the door is closed, one switch pole 6a of which connects the signaling line 3 to earth or earth 7 and the other switching pole 6b of which is connected the mass 7 is arranged in a line 8 which is connected via a resistor 9 to a line 10 to a voltage source symbolized by a plus sign.
  • the line 8 leads via a delay element 11 to an input of a first OR gate 12.
  • a line 15 or 16 is connected to two further inputs of the OR gate 12 via an inverter 13 or 14, respectively.
  • Line 15 is connected via a resistor 17 to the line 10 and leads to a switch 18 which, for example, controlled by a light barrier or the like, is closed only when a person approaches the door or when the door is used.
  • the inputs of a first AND gate 21 are connected directly to the signal line 1 for the door release signal or via an inverter 22 to the signal line 2 for the closing request signal.
  • the output of the first AND gate 21 is connected to the inputs of a second and a third AND gate 23 and 24, respectively.
  • the output of the second AND gate 23 is connected via a second OR gate 25 to a solenoid valve 26, upon excitation of which a cylinder, not shown, for actuating the door in the opening direction of the door is pressurized with compressed air.
  • the output of the first OR gate 12 is connected via a timing element causing a drop delay, a resistor 28 bridged by a diode 27 and a downstream capacitor 29 to ground, and a downstream Schmitt trigger 30 with the second input of the second AND gate 23 and an inverter 31 connected to the second input of the third AND gate 24.
  • a solenoid valve 33 is connected to the output of the third AND gate 24 via a third OR gate 32, which, when energized, acts on the compressed air cylinder serving to actuate the door in the closing direction, acting on compressed air.
  • the two inputs of an exclusive NOR gate 34 are also connected to the two signal lines 1 and 2, the output of which monitors a relay switch 35, which connects the signal line 3 to ground 7 when the NOR gate 34 carries the signal.
  • the function block 5 for the forced closing has a fourth AND gate 36, one input of which is connected directly to the signal line 2 for the closing request signal and the other input of which is connected via an inverter 37 to the signal line 1 for the door release signal.
  • the output of the fourth AND gate 36 is connected to the reset input of a shift register 38 and, via a delay element 39, to an input of a fifth AND gate 40.
  • An input of a sixth AND gate 41 is connected to the output of the fifth AND gate 40, the second input of which can be controlled by the output of a seventh AND gate 42.
  • the output of the sixth AND gate 41 is connected to the input of a first, monostable, non-retriggerable multivibrator 43 and the second input of the third OR gate 32.
  • the output of the first multivibrator 43 is connected to an input of a fourth OR gate 44, the output of which is connected to the reset input of a second multivibrator 45, and to the reset input of a third multivibrator 46.
  • the output of the second multivibrator 45 is connected to the clock input of the shift register 38 and, in each case via an inverter 47 or 48, to the input of the third multivibrator 46 or an input of the seventh AND gate 42.
  • the second input of the second OR gate 25 is connected to the output of the second multivibrator 45 via a fifth OR gate 49.
  • the output of the third multivibrator 46 is connected to an input of the fourth OR gate 44 and, via an inverter 50, to the second input of the seventh AND gate 42.
  • a connection leads from the output of the delay element 11 to a third input of the fourth OR gate 44.
  • the shift register 38 has a switching device 52 by means of which the number of control pulses required at its clock input can be set arbitrarily, after reaching which the shift register 38 outputs an output signal via an inverter 53 to an input of an eighth AND gate 54.
  • At a second input of the eighth AND gate 54 is via a first NOR gate 55 a clock 56 connected.
  • a connection leads from the output of the fifth AND gate 40 to a third input of the eighth AND gate 54 and to a reset input of a fourth multivibrator 57.
  • the output of the eighth AND gate 54 is connected to the input of the second multivibrator 45.
  • the output of the fourth AND gate 36 is connected via an inverter 58 to an input of a second NOR gate 59, the output of which is connected to the input of the fourth multivibrator 57.
  • Connections lead from the output of the fourth multivibrator 57 to the second input of the fifth OR gate 49 and via a further inverter 60 to the second input of the fifth AND gate 40.
  • the second inputs of the first and second NOR gates 55 and 59 are common connected to the output of a ninth AND gate 61, the inputs of which are connected to lines 15 and 16.
  • the control device works as follows:
  • switches 18 and 20 should also be open. Under these conditions, lines 8, 15 and 16 from line 10 carry voltage and thus carry signals; a signal is present at delay input 11 at one input of first OR gate 12, while the other two inputs of first OR gate 12 about the Inverters 13 and 14 are signal-free.
  • the ninth AND gate 61 controlled via the two lines 15 and 16 supplies signals to the inputs of the two NOR gates 55 and 59, so that their outputs are signal-free.
  • the first OR gate 12 emits a signal via the diode 27, which instantaneously charges the capacitor 29 and reaches the input of the second AND gate 23 sharpened via the trigger 30.
  • the signal routing in the signal lines 1 and 2 controls both inputs of the first AND gate 21, so that this emits a signal to the second input of the second AND gate 23 and to an input of the third AND gate 24; however, the inverter 31 keeps the second input of the third AND gate 24 signal-free.
  • the second AND gate 23 therefore emits a signal while the third AND gate 24 is blocked.
  • the output signal of the second AND gate 23 passes through the second OR gate 25 to the solenoid valve 26, whereby this is excited and pressurizes the actuating cylinder for the door in the opening direction.
  • the door does not open automatically, however, but remains closed for the time being.
  • the solenoid valve 33 Since there is no signal for the forced closing from the output of the third AND gate 24 or from the switched-off function block 5 to the third OR gate 32, the solenoid valve 33 remains de-energized and keeps the actuating cylinder for the door movement pressure-free on the closing side.
  • the compressed air acting on the actuating cylinder caused by the solenoid valve 26 opens the door.
  • the switch 6 closes, so that a signal routing in the signal line 3 is suppressed by the switching pole 6a, as a result of which the indicator lamp mentioned lights up in the driver's cab, and at the same time the signal routing in the line 8 by the switch pole 6b is connected to the ground 7 is ended.
  • the timing element 11 debounces the signal routing at the input of the first OR gate 12 ends, so that the capacitor 29 gradually begins to discharge through the resistor 28.
  • the voltage across the capacitor 29 has dropped such that the Schmitt trigger 30 ends the signal output.
  • the second AND gate 23 blocks and the third AND gate 24 opens as a result, so that the excitation of the solenoid valve 26 is ended via the second OR gate 25 and excitation of the solenoid valve 33 is started via the third OR gate 32.
  • the compressed air supply to the actuating cylinder for the door is therefore reversed, so that the door begins to close automatically. If a person now approaches the door or if this person uses the door, the switch 18 closes, as a result of which the signal routing in line 15 is ended. If a person or an object is jammed at the door during the mentioned closing process, the switch 20 closes and ends the signal routing in line 16.
  • the termination of the signal routing in line 15 and / or 16 causes via the inverter 13 or / and 14 a control of the first OR gate 12 so that it again emits a signal and drives the Schmitt trigger 30 via the diode 27 with almost instantaneous charging of the capacitor 29, which then immediately emits a signal which the two AND gates 23 and 24 in turn reversed, so that the action acting in the closing direction of the compressed air cylinder is interrupted via the two solenoid valves 26 and 32 and a renewed pressurization of the compressed air takes place in the opening direction.
  • the door thus opens again, so that the door can be used freely without the risk of being pinched.
  • the output signal of the first OR gate 12 goes out again, so that, as described above, the door closes again after the time period specified by the capacitor 29 and the resistor 28.
  • the door closes the door is fully closed again and its locking engages.
  • the switch 6 opens, so that again by energizing the line 8, as already described, the solenoid valve 26 is again energized and the solenoid valve 33 is de-energized.
  • the actuating cylinder for the door is thus pressurized again in the opening direction, but the door remains closed due to its locking until a subsequent, arbitrary opening of this locking.
  • the signal routing in signal lines 1 and 2 is reversed, i.e. the signal for the door release is ended and instead the signal for the closing request is initiated, the first AND gate 21 drops out, so that by Failure of a signal at each input of the two AND gates 23 and 24, the function block 4 for closing or reversing is switched off, no signal can reach the solenoid valves 26 and 33 from the two AND gates 23 and 24.
  • the fourth AND gate 36 is activated by the signal present in the signal line 2 and via the inverter 37, so that it outputs a signal at its output. This signal resets the shift register 38 and results in no signal routing via the inverter 58 corresponding input of the second NOR gate 59 and arrives via the delay element 39 debounced and delayed to the fifth AND gate 40.
  • the closing process initiated in this way lasts at least for the period of time specified by the first multivibrator 43: If a person approaches the door during this period or there is a pinching process, the switches 18 and / or 20 are closed, so that the ninth AND gate 61 the Signal routing to NOR gates 55 and 59 is ended. While the fourth multivibrator 57 is still kept blocked by the signal emitted by the fifth AND gate 40, the first NOR gate 55 causes the intermittent signal output by the clock generator 56 to the eighth AND gate 54. Since the fifth AND gate 40 and the inverter 53 also carries the other inputs of the eighth AND gate 54, the start input of the second multivibrator 45 is controlled.
  • the second multivibrator 45 If the time period specified by the first multivibrator 43 has not yet expired at this time, the second multivibrator 45 remains blocked, however, and the closing process runs continuously for the remaining time of the time period given by the first multivibrator 43. However, if the time period specified by the first multivibrator 43 has already expired and the output signal of this multivibrator has ended, the second multivibrator 45 starts by the signal output by the eighth AND gate 54 and gives for a specific time period during which the door is reversed or entered Reopening process, an output signal.
  • This output signal keeps the input of the third multivibrator 46 via the inverter 47 and an input of the seventh AND gate 42 via the inverter 48 signal-free, the third multivibrator 46 therefore still does not emit an output signal and the seventh AND gate 42 ends its output signal so that the sixth AND gate 41 also drops and its output signal ends.
  • Solenoid valve 33 is thus de-energized via third OR gate 32, while at the same time the output signal of second multivibrator 45 via fifth OR gate 49 and second OR gate 25 excites solenoid valve 26 to initiate the reopening process of the door. This reopening process or the reversing of the door continues for the time period specified by the second multivibrator 45.
  • the output signal of the second multivibrator 45 goes out, as a result of which the third multivibrator 46 is started via the inverter 47 and outputs an output signal for a further, specific time period.
  • the seventh and thus also the sixth AND gate 42 and 41 remain blocked.
  • the solenoid valve 26 also drops out via the OR gates 49 and 25, so that both solenoid valves 26 and 23 are now deenergized for the period of time specified by the third multivibrator 46 and the door becomes indifferent without auxiliary power Condition in which it can be easily moved by hand.
  • This indifferent door state which is brought about by switching off any compressed air supply to the cylinder actuating the door, lasts for the time period specified by the third multivibrator 46.
  • the output signal emitted by this multivibrator 46 blocks the second multivibrator 45 via the fourth OR gate 44, so that the switches 18 and / or 20 are closed again via the first NOR gate 55 and the eighth AND gate 54 can trigger the second multivibrator 45 to start again, the latter rather remains at rest with a signalless output.
  • the third multivibrator 46 After the time period specified by the third multivibrator 46, its output signal goes out, whereupon the two AND gates 42 and 41 again emit signals which initiate a closing process for the door via the OR gate 32 and the solenoid valve 33 and start the first multivibrator 43.
  • the output signal of this multivibrator 43 which is pending for the period of time specified by the multivibrator 43 resets the multivibrator 46 and blocks the two multivibrators 45 and 46, so that closing of the switches 18 and / or 20 during this period does not restart the Multivibrators 45 can cause. The closing process of the door therefore continues again for the time period specified by the multivibrator 43.
  • the clock generator 56 is required to make the output signals of the first NOR gate 55 and thus the eighth AND gate 54 dynamic, so that the second multivibrator 45 can be started reliably by a rising signal edge.
  • switches 18 and 20 remain open, so the closing process continues until the door is completely closed and locked. If after the expiry of the time period specified by the fourth multivibrator 57 up to the point in time at which the door is closed when the switch 6 is opened, a person wants to use the door again, the switch 18 and / or 20 closes, as a result of which the second Multivibrator 45 is started and the above-described processes with reopening or
  • a fourth blocking signal is present at the reset input of the second multivibrator 45 via the fourth OR gate 44, so that even when the Switch 18 attempted use on the door the second multivibrator 45 cannot be started and the door thus remains closed.
  • the output signal emitted by the fifth AND gate 40 at this time blocks the fourth multivibrator 57, so that the door cannot be reopened in this way either.
  • the signal line 3 is only connected to ground 7 when the door is closed through the switch pole 6a and with exclusive signal routing in one of the signal lines 1 or 2 through the relay switch 35 and is thus signal-carrying so that a departure can take place.
  • At least one microprocessor can be used for at least one of the function blocks.
  • the controller can also be designed at least largely as a circuit integrated in a module.
