Definitions

  • Electropneumatic door controls with a reversing device are mainly used in public transport that serve to transport people, such as. B. used in buses.
  • the controls are usually operated pneumatically or electropneumatically, i. H. to open or close the door, the driver triggers a pneumatic or electropneumatic pulse which, via a door valve formed as a control valve, applies compressed air to a door drive designed as a door cylinder, the lifting movements of the door cylinder piston triggering the opening and closing movements of the door.
  • the door control therefore contains two basic components, namely a pneumatic part and electronics. These components are shown in Figures 1 and 2 of the aforementioned DE-OS 30 32 516.
  • the invention is therefore based on the object of specifying a circuit expansion of the known electronics by means of which these three additional ones Properties can be realized in a simple way.
  • a compressed air supply 31 is connected to a pneumatic door drive 2 via an emergency valve 15, a valve 24 and a door valve 1.
  • the door drive 2 consists of one working cylinder 9, 10 for driving one of the two door leaves.
  • the working cylinder 9 contains two chambers 11, 12 and a piston 13.
  • the working cylinder 10 is constructed accordingly.
  • the chambers 11, 12 of the working cylinder 9 are each connected to the two inputs of a reversing switch 18. Accordingly, the chambers of the working cylinder 10 are connected to a reversing switch 19.
  • the reversing switches contain electrical switching contacts 36, 37, 38, 39.
  • the contacts 37 and 39 are in parallel and are connected to terminals 32 and 35.
  • the contacts 36 and 38 are also parallel and are connected to terminals 33 and 34.
  • connection 32 is connected via a limit switch 20 to an output 3 of electronics 22.
  • the connection 33 is connected to an input 7 of the electronics 22.
  • the connection 34 is connected to an input 6 of the electronics 22.
  • the connection 34 is also connected to an operating voltage via a further limit switch 21.
  • the two limit switches 20 and 21 each have two contacts connected in parallel, each of which belongs to one of the two door leaves of a door.
  • Electronics 22 also has an input 8, which is connected to an operating voltage via a button 14. Another output 4 of the electronics 22 is connected to a working magnet 16 for actuating the door valve 1. Finally, an output 5 of the electronics 22 is connected to a working magnet 25 for actuating the door valve 1.
  • the door is reversed in the usual way by actuating the button 14.
  • the door valve 1 is thereby reversed and the previously vented chambers of the door cylinders 9, 10 are ventilated.
  • two limit switches 20, 21 are provided, by which the reversing command is interrupted in the end positions.
  • valve 24 When an obstacle is caught by the rear edge of the door during opening, the valve 24 is excited by a signal at the output 3 of the electronics 22, which runs via the limit switch 20 and the switching contacts 37, 39 to the working magnet 23. As a result, the door cylinders 9, 10 are vented.
  • FIG. 2 shows a block diagram of the electronics 22 according to FIG. 1.
  • the signal conditioning 27 is connected with the input 6 to the limit switch 21, with the input 7 to the reversing switch connection 33 and with the input 8 to the button 14.
  • the signal processor 27 picks up the signals of the connected switches or pushbuttons and adjusts them to the voltage conditions in the subsequent electronics with the aid of a damping network (eg RC combination) and with Schmitt triggers.
  • the door position flip-flop 26 simulates the respective door position. When the electronics 22 are switched on, the flip-flop 26 is preset in accordance with the limit switch position and then always reversed together with the door valve 1. As a result, the respective door state is stored in flip-flop 26.
  • the monitoring logic 28 recognizes from the position of the door position flip-flop 26 and the door command given with the button 14 whether or which monitoring function is permitted.
  • the control logic 29 receives the door command and the signals from the monitoring logic 28, links them and forwards them to the solenoid valve control 30.
  • the solenoid valve control 30 contains power output stages for controlling the door valve 1 (output 5 and output 4). In addition, the valve is reversed via the output 3 and the working magnet 23.
  • the monitoring functions can be suppressed by a push button 14 by means of a permanent door command.
  • the door can be opened and closed even in the event of stiffness or obstruction by snow and ice in winter. If due to carelessness by the driver If a passenger is trapped with a permanent door command, the corresponding monitoring function (reversing) automatically takes effect again after the door command has been released.
  • the ventilation is suppressed in the same way in the event of an obstacle in the opening direction. If the door is opened by a signal at input 8, the release of the trailing edge monitoring is suppressed by monitoring logic 28 as long as the door command is present at input 8. The door can thus be fully opened even with a handicap due to ice and snow by a continuous pulse on the button 14 without the door being vented by the monitoring. If the door command is ended, the monitoring logic releases the trailing edge monitoring again and controls the output 3 via the control logic 29 and the magnet control 30. If the end position of the door has not yet been reached (limit switch 20 still closed) and there is an obstacle in the door, the door is immediately depressurized.
  • a 3/2-way valve 48 air passes from an air tank 31 via a throttle check valve 49 to a pressure reducer 50. This reduces the service brake pressure to e.g. B. 3 bar. If there is now a lower brake pressure than the pressure set on the pressure reducer 50 on a subsequent 2-way valve 51 from the service brake system, the vehicle is braked via a brake cylinder 52 with the reduced pressure of 3 bar.
  • the command for this is given by an electrical pulse to the 3/2-way valve 48.
  • This impulse can e.g. B. be given by a switch on the dashboard by the driver himself or realized by limit and pressure switch links.
  • an additional output 46 is created on the solenoid valve control 30 of the electronics, which directly controls the 3/2-way valve 48 of the stop brake.
  • This additional output 46 is controlled by a stop logic 43 which links the input for the door position with input 8 for the door command and input 40 for the 3 km / h detection.
  • This connection is made in such a way that the output 46 of the solenoid valve control 30 is at + 24 V when the doors are open after a vehicle speed of 3 km / h has been undershot and a door command has been entered.
  • the output 46 is only switched off again if a door command has been given before the doors are closed.
  • This logical link makes the function of the stop brake independent of fluctuating pressure values in the door system and thus of malfunctions in the event of pressure loss in the system.
  • the logical link is not solely dependent on the door position, as a door command must also be given on the dashboard beforehand.
  • the stop brake When the emergency stop of the door system is operated and the door leaves are closed by hand, the stop brake remains activated. The driver is relieved because the stop brake is applied when the stop brake is actuated and also when the door is opened. The stop brake does not have to be applied to open the door. The link with the 3 km / h detection ensures that the vehicle comes to a standstill before the door is opened.
  • a door closing warning system is intended to alert the passengers to the impending closing before the door closes by means of an acoustic warning signal.
  • the door position flip-flop 26 contained in the electronics is in the open direction.
  • the next door command must reverse the flip-flop 26 in the closed direction. If the door position flip-flop 26 is in the open direction and the next door command reaches the electronics via input 8, an adjustable timer 44 is set. For the duration of the timer, the monitoring logic 28 is blocked and an acoustic signal generator 45 is activated. This means that the execution of the door command and thus the reversal of the door in the closed direction takes place only after the running time of the timer 44.
