Definitions

  • the invention relates to a circuit arrangement for remote control and monitoring of actuators for motor-operated slides or valves in the field of district heating supply within individual objects, in which two commands and the multiple of messages are to be transmitted in opposite directions via a long-distance line.
  • the field of application of the invention is control technology.
  • a circuit arrangement according to DD-PS 31 717 is known, by means of which a double command and in the opposite direction a double message by means of half-waves of an alternating current are to be transmitted via a control wire and a common connecting line.
  • This arrangement requires, for example, 10 + 1 control wires to transmit ten double commands and ten dependent double messages.
  • This circuit arrangement requires 5 + 3 control wires for the transmission of ten double commands and ten dependent double messages.
  • command-dependent messages Another disadvantage when using the multi-wire method is that only information with mutual dependency - so-called command-dependent messages, the number of which corresponds to the command volume - can be transmitted via a control wire. With additional transmission of command-independent messages, the overhead costs for transmission lines continue to increase.
  • the object of the invention is to provide a circuit arrangement for remote control and monitoring of actuators, with which the transmission of commands and messages for an actuator is made possible with maximum functional reliability, minimal transmission line expenditure and low power consumption, two commands and the multiple thereof Number of messages can be transmitted in opposite directions over a long-distance line.
  • the circuit arrangement is characterized by the termination of the long-distance line, in which commands in one direction and messages in the other direction are transmitted by means of positive and negative half-waves, in the branch, directly on the actuator by four optocouplers, the output of the first Optocoupler for the transmission of the message "OPEN / TRAVEL OPEN" with the input of the second optocoupler for receiving the command "CLOSED", the input of the third optocoupler for receiving the command "OPEN” with the output of the fourth optocoupler for the transmission of the Message "ZU / FAHRT ZU" is connected, and at the input of the second and at the input of the third optocoupler which has a pole of an alternating voltage and the output of the first and the output of the fourth optocoupler are each connected to a common long-distance line via diodes which are switched in opposite directions.
  • the long-distance line is terminated by two switchable, electronic constant current sources as command elements, each in series with a light-emitting diode, the anode of the light-emitting diode for displaying the messages "OPEN / RUN OPEN” with the emitter of the first switchable constant current source for the command " CLOSE "and the cathode of the light emitting diode Display of the messages "CLOSE / DRIVE CLOSED" is connected to the collector of the second switchable constant current source for the "OPEN" command.
  • the collector of the first and the emitter of the second switchable, electronic constant current source lie on the other pole of the alternating voltage and the cathode of one and the anode of the other light-emitting diode lie on opposite common diodes on the common transmission line.
  • the limit switches assigned to the two stable positions of the actuator in the external unit simultaneously place the one signal at the set input of the one message memory for the message "CLOSE”, at the clear input of the command memory for the command "CLOSE”, at the input of the Amplifier for the downstream optocoupler for message transmission "CLOSE / TRAVEL CLOSE”, which are assigned to the one stable position of the actuator and to the delete input of the other message memory for the message "OPEN”, to the input of the direction lock for the command "OPEN” and to the negative input of the comparator for the message "RUN OPEN” which are assigned to the other stable position of the actuator.
  • the other signal of the actuator is simultaneously sent to the set input of the other message memory for the message "OPEN”, to the clear input of the command memory for the command "OPEN”, to the input of the amplifier for the downstream optocoupler for message transmission "OPEN / TRAVEL OPEN", which are assigned to the other stable position of the actuator.
  • This signal is also to the clear input of a message memory for the "CLOSE” message, to the directional lock input for the "CLOSE” command and to the negating input of the comparator for the "CLOSE CLOSE” message, which of the one stable position of the Actuator are assigned.
  • the comparator for the message “DRIVE UP” has an input at the output of the flashing clock generator and its output at the amplifier for the optocoupler for the Messages "OPEN / DRIVE UP”, while the comparator for the message “DRIVE CLOSE” with one input at the output of the message memory for the message "OPEN”, with the other input at the output of the flashing clock generator and with its output at the input of the amplifier for the Optocoupler for the messages "CLOSE / TRAVEL CLOSE".
  • the AC signal voltage of the signals switched by the optocouplers for the transmission of the messages to the long-distance line simultaneously serves as the operating voltage for the switchable, electronic constant current sources within the command point.
  • the circuit arrangement has been developed for actuators which actuate sliders with two stable positions by means of a motor drive, namely slider open (OPEN) or slide closed (CLOSE), the running time from one to the other stable position being in the range of minutes and depending on the size and application of the Actuator is.
  • OPEN slider open
  • CLOSE slide closed
  • the motor drive M is switched off in the running direction assigned to it by means of a limit switch.
  • Two further limit switches dz and da are used to generate signals for the two messages “OPEN” and “CLOSED”.
  • the circuit arrangement operates in the trunk line circuit FL 1, FL 2 on a quiescent current basis;
  • Each stable position of the actuator M is assigned positive and negative half-waves of an AC voltage Ws, which serve in the command point KS in conjunction with the LEDs VLA, VLZ for the visual display of the messages "OPEN - CLOSE", and at the same time as the operating voltage of both command elements TA, TZ .
  • the transmission of one of the pending Notification of opposite command - notification "CLOSE” command "OPEN”, notification “OPEN” command “CLOSE” - is carried out by interrupting the continuous signal transmitted with negative or positive half-waves within the command station KS by means of the command elements TA, TZ.
  • Negative half-waves are transmitted and received within the branch office AS by two optocouplers MAO, BZO;
  • the MZO, BAO optocouplers are assigned to positive half-waves.
  • the AC voltage Ws is fed in at the inputs E 1 and E 2 of the optocouplers BAO and BZO for receiving the commands "OPEN" and "CLOSE".
  • the input E 2 of the optocoupler BZO is connected to the output A 2 of the optocoupler MAO, the output A 1 of which is connected to the common trunk line Fl 1 via the diode V 1.
  • the input E 1 of the optocoupler BAO is connected to the output A 1 of the optocoupler MZO, the other input A 2 of which is also connected to the common trunk line Fl 1 via the diode V 2.
  • the LED VLA for the optical display of the message “OPEN” and the command element TZ for the command "CLOSE” and the LED VLZ are in series with two diodes V 3, V 4 connected in opposite directions for the visual display of the message "CLOSED” and the command element TA for the command "OPEN".
  • the other pole of the alternating voltage Ws is connected to the collector of one command element TZ and to the emitter of the other command element TA.
  • the time selection BA 3 sends its output signal to the command memory BA 1 and thus the information "OPEN" is written.
  • the actuator M is switched on via the amplifier BAV for the "OPEN" command. If command impulses that are too short or too long are input, the time selection BA 2 evaluates them as a fault and the "OPEN" command is not executed.
  • the signal present at the delete input of the message memory MA 1 for the "OPEN” message and that at the negated input of the comparator MA 2 for the message "TRAVEL OPEN” and at the delete input of the command memory BZ 1 for the "CLOSE” command is canceled. Since the information written in the message memory MZ 1 for the message "CLOSED" is retained until the other stable position of the actuator M is reached, the signal at the comparator MA 2 becomes effective for the message "RUN OPEN". In connection with the pending signal of the blinking clock generator TG, the amplifier MAV for the optocoupler MAO is controlled by the comparator MA 2 for the message "DRIVE UP", by means of which the blinking cycle is switched to the trunk line F1 with negative half-waves.
  • a permanent signal is applied to both inputs of the message memory MZ 1 and MA 1 by the "ON SITE" switch, both of which block each other via their negated inputs.
  • This continuous signal is simultaneously transmitted to the command point KS via the amplifiers MAV and MZV in conjunction with the downstream optocouplers MAO and MZO with negative and positive half-waves, and is indicated there optically by the two LEDs VLA and VLZ.
