Definitions

  • the invention relates to a door security circuit for monitoring at least one floor door of an elevator system, which has a transmitter and a receiver, wherein a non-electrical signal generated by the transmitter, which is influenced by a locking device of the floor door, is fed to the receiver for conversion into an electrical signal.
  • a safety circuit is known from patent specification FR 1 432 651, in which a door latch for elevator systems monitored by means of a photoelectric device is disclosed. If the door latch has a certain position, the light beam emitted by a light source of the photoelectric device reaches a photosensor, the electrical signal of which is passed on to the elevator control.
  • a disadvantage of the known device is the susceptibility to interference of the transmitter and receiver, which are exposed to shocks with each bolt movement and are therefore subject to excessive stress.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of avoiding the disadvantages of the known device and of designing a security circuit so that locking devices of several storey doors can be monitored by means of a transmitter and a receiver by means of non-electrical signals.
  • the advantages achieved by the invention are essentially to be seen in the fact that the safety circuit according to the invention can be used in rooms with normal climatic conditions as well as in wet rooms and rooms at risk of explosion. This enables the door security circuits to be standardized, which in turn results in significant cost savings in terms of manufacture, assembly, maintenance and spare parts. Further advantages can be seen in the fact that better fault analysis per floor as well as preventive maintenance work are possible.
  • the safety circuit according to the invention is immune to electromagnetic interference.
  • 1 denotes a transmitter which generates a non-electrical signal, the non-electrical signal being directed from a first conductor section 2 to a locking device 3 of a first floor door, not shown.
  • the non-electrical signal is conducted to a third wire section 5 by means of a second conductor section 4 arranged on the locking device 3 of the first floor door and from there to a locking device 3 of a second floor door, not shown.
  • the non-electrical signal is not passed to a fifth wire section 8 by means of a fourth conductor section 7 arranged on the locking device 3 of the second floor door, so that this does not pass on a non-electrical signal to a receiver 9.
  • the elevator installation has two storey doors.
  • the locking devices of the further storey doors are connected in series by means of further conductor sections.
  • a direct conductor 10 for testing transmitter 1 and receiver 9 and on the other hand sensors 11; 12; 13 for testing the conductor sections 2; 4; 5; 7; 8 provided.
  • One sensor 11 per conductor section; 12; 13 is provided, the signal of which is fed to a circuit for failure detection 14.
  • error detection per floor as well as preventive maintenance work in the safety circuit are made considerably easier.
  • FIGS. 2 to 6 show a first embodiment variant of the safety circuit explained in FIG. 1.
  • a light source is provided as the transmitter
  • a light guide is provided as a means for directing the non-electrical signal
  • a photoelectric element is provided as a receiver, which converts the non-electrical signal in the form of constant light into an electrical signal.
  • an outgoing light guide 16 is arranged on a movable part 15 of the locking device 3 shown in the working position and an outgoing light guide 18 is arranged on a fixed part 17 of the locking device.
  • the ends of the light guides 16; 17 are aligned and spaced such that the light emerging from the outgoing light guide 16 can enter the outgoing light guide 18.
  • the movable part 15 of the locking device 3 is pivoted about a pivot point 19, so that the light can no longer be transmitted from the outgoing light guide 16 to the outgoing light guide 18.
  • the outgoing light guide 16 and the outgoing light guide 18 is arranged on the fixed part 17 of the locking device 3.
  • a light guide loop 20 is arranged on the movable part 15 of the locking device 3 such that the light guides 16, 18 are optically connected to one another in the working position of the locking device 3 shown.
  • FIG. 4 shows locking devices 3 connected in series by light guides.
  • the locking devices 3 shown in the working position optically connect the light guide sections with their light guide loops 20, as a result of which an optical passage is established across all locking devices 3 and as a result of which the door security circuit reports all storey doors as closed.
  • FIGS. 5 and 6 show an embodiment variant with a reflector 21 arranged on the locking device 3 and made of, for example, chromed plastic, in which the transmitter 22 emits pulse-like light by means of a first photodiode 23, which is guided by the light-guiding light guide 16 to the reflector 21.
  • An outgoing light beam 24 emanating from the light-guiding light guide 16 is deflected by the reflector 21 into a light beam 25 leading away and received by the light-guiding light guide 18, which guides the light onto the reflector 21 of the subsequent locking device 3.
  • After the light is guided over all reflectors 21 of the locking devices connected in series in the safety circuit, it is converted into an electrical control signal by a second photodiode 26, an amplifier 27 and a converter 28.
  • photo sensors (not shown) are provided, which monitor the light beam and whose signal is fed to a circuit (not shown) for failure detection, with which the switching states are monitored centrally on all locking devices 3 and evaluated for fault analysis and preventive maintenance work.
  • a pressure source is provided as the transmitter, a pressure line as the conductor of the non-electrical signal and a pressure transducer as the receiver, a pressure medium pressurized by the pressure source, for example a gas by means of the pressure line via the locking device 3 is directed to the pressure transducer, which converts the pressure prevailing in the pressure medium into an electrical signal.
  • a pressure line leading pressure medium is arranged, which is connected to a pressure medium leading pressure line when the floor door is closed.
  • a pressure line loop can be arranged on the movable part 15 of the locking device 3 instead of the pressure line leading the pressure medium, which pressure loop connects the pressure line leading the pressure medium to the pressure line leading the pressure medium away when the storey door is closed.
  • a clamping device can also be arranged instead of the pressure line leading the pressure medium, which prevents the pressure spreading in the pressure line by clamping when the storey door is open.
  • pressure sensors are provided, which monitor the pressure and whose signal is fed to a circuit for failure detection, with which the switching states on all locking devices 3 are monitored centrally and evaluated for fault analysis and preventive maintenance work.
  • a sound source is provided as the transmitter, a sound line as the conductor of the non-electrical signal and a sound transducer as the receiver, mechanical waves generated by the sound source in the form of constant or pulse-like sound by means of the sound line via the Locking device 3 are directed to the transducer, which converts the sound into an electrical signal.
  • a sound-conducting formwork line is arranged, which is connected to a sound-path-leading pressure line when the storey door is closed.
  • a formwork line loop which connects the sound-guiding formwork line to the sound-guiding formwork line when the storey door is closed.
  • a clamping device can also be arranged instead of the sound-conducting formwork line, which prevents the sound propagation in the formwork line by clamping when the storey door is open.
  • sound sensors are provided which monitor the sound and whose signal is fed to a circuit for failure detection, with which the switching states are monitored centrally on all locking devices 3 and evaluated for fault analysis and preventive maintenance work.
  • a pressure source is provided as the transmitter, a pressure line as the conductor of the non-electrical signal and a barrier as the receiver, a pressure medium pressurized by the pressure source using a body, for example a ball or a cylinder Pressure line is moved via the locking device 3 to the barrier, which converts the passage of the body into an electrical signal.
  • a body for example a ball or a cylinder Pressure line
  • a pressure line loop can be arranged instead of the pressure line leading to the pressure medium closed floor door connects the pressure line leading the pressure medium with the pressure line leading pressure medium away.
  • a clamping device can also be arranged on the movable part 15 of the locking device 3 instead of the pressure line leading to the pressure medium, which prevents the passage of the body by clamping the pressure line when the storey door is open.
