Definitions

  • the invention relates to a measuring device for an elevator installation with at least one elevator car according to the preamble of the independent claim.
  • the invention relates to a corresponding elevator installation.
  • elevator cars in elevator systems are each equipped with their own drive and their own braking system.
  • the electronic control of the entire elevator system is often designed so that there should be no collisions of the individual elevator cars to stationary obstacles connected to a roadway, such as a roadway end or to an adjacent elevator car.
  • the roadway is defined by a shaft and a track end by a shaft end.
  • the roadway may also be designed as a truss or box construction or further.
  • Under roadway both the directly claimed by an elevator car room as well as the adjoining room, which is limited for example by the shaft space understood.
  • an emergency stop or even with a normal floor stop of a cabin can not be guaranteed under all circumstances that an upper or lower located on the same roadway further elevator car can stop in time to avoid a collision. This could be avoided by giving the controller sufficient distances between the individual elevator cars and also adapted vertical speeds.
  • Such a requirement can not fully exploit the transport capacity of an elevator installation, which has an impact on the cost-benefit efficiency.
  • an elevator system which comprises means for opening the safety circuit of an elevator car, if it comes to an undesired approach to another elevator car.
  • safety modules are present at each elevator car, which evaluate the cabin positions and speeds to possibly trigger braking operations on other elevator cars can.
  • the individual safety modules must always know and evaluate the cabin positions and speeds of the other elevator cars involved in order to be able to react correctly in an emergency. This requires a special decision module, which is responsible for determining the stop commands in an emergency.
  • the present invention is equally suitable for preventing a collision between two elevator cars that are relatively approaching, and for preventing a collision between an elevator car and a track end.
  • equivalent variants of the measuring device according to the invention for an elevator installation will be described.
  • the measuring device has an elevator installation with at least one elevator car, which is movable along a roadway of the elevator installation, via at least one transmitter and at least one receiver.
  • a receiver is arranged on an elevator car and a transmitter on the roadway and / or a transmitter is arranged on an elevator car and a receiver on the roadway.
  • the transmitter emits a beam at a first angle with respect to the direction of travel. The first angle is predetermined such that when the elevator car approaches an obstacle which is stationary relative to the roadway, the beam strikes the receiver.
  • the measuring device is according to the first variant so redundant interpretable.
  • a transmitter are arranged on the roadway and a receiver on a first elevator car.
  • a second pair of transmitter and receiver is reversed, that is, the transmitter on the elevator car and the receiver arranged on the roadway.
  • a redundant design of the measuring device can also be achieved in that two transmitters are arranged on the roadway and two receivers on the elevator car.
  • the measuring device has an elevator installation with at least one elevator car, which is movable along a roadway of the elevator installation, via at least one transmitter and at least one receiver.
  • a receiver and a transmitter are arranged on an elevator car and / or a receiver and transmitter are arranged on a roadway.
  • the transmitter emits a beam at a first angle with respect to the direction of travel. The first angle is predetermined such that when the elevator car approaches an adjacent elevator car or an obstacle which is stationary relative to the roadway, the beam strikes the receiver.
  • the measuring device preferably has at least one reflector which reflects a beam emitted by the transmitter to the receiver. If the transmitter and the receiver are arranged on the roadway, the reflector is attached to the elevator car. Conversely, the reflector is attached to the roadway, when the transmitter and receiver are arranged on the elevator car. Also in this second variant, the measuring device is redundant interpretable. For this purpose, a pair of transmitters and receivers are arranged on the elevator car and on the roadway. In addition, a redundant design of the measuring device can also be achieved in that two transmitters and two receivers are arranged on the elevator car or on the roadway.
  • the measuring device has an elevator installation with at least one elevator car, which is movable along a roadway of the elevator installation, via at least one transmitter and at least one receiver.

  • An additional transmitter and receiver are in this case arranged on the elevator cars such that either two transmitters are arranged on a first elevator car and two transmitters are arranged on a second elevator car or a respective transmitter and receiver are arranged on a first and a second elevator car.
  • the measuring device according to the invention can be equipped with one or more reflectors, which are arranged on an elevator car and / or on the roadway and reflect a beam incident from the transmitter to a receiver.
  • the senor emits a beam that can be detected by an associated receiver.
  • This transmitter and receiver pair and optionally one or more associated reflectors are arranged in the region of the roadway and the elevator cars so that when moving one or more elevator cars the beam of the transmitter on the receiver and / or possibly on a reflector generates a traveling measurement point.
  • the receiver and / or the reflector thereby define a temporal or local reaction region in which a suitable reaction can be triggered. This reaction area can be used, for example, to compensate for system reaction times or building tolerances.
  • the receiver has a sensor area with one or more sensitive sensor areas for detecting the beam. If the sensor area is subdivided into several sections, these can preferably be evaluated separately.
  • the receiver preferably comprises an evaluation system in order to be able to trigger an adapted reaction as a function of which of the sections the beam strikes.
  • this sensor area is arranged perpendicular to the elevator car or on the roadway. This minimizes the settling of dust particles on the sensor area. To better protect the sensor area from the deposition of dust particles, it is overhanging with respect to a vertical direction, i. with the sensitive sensor side inclined downwards in an angle range from 0 to 90 °, can be positioned. This variant is preferably used in conjunction with a reflector.
  • the beam generated by the transmitter can be based on different physical principles.
  • the beam comprises electromagnetic, electrical, or magnetic waves, sound or light waves.

Since each section can be evaluated separately, the sensor can be evaluated with regard to the position of an elevator car as long as it is within the range of the migrating measuring point. With an appropriate length of the sensor area and / or positioning of the transmitter, receiver and / or reflectors and / or the adjustment of the angle, the measuring device can also be used as absolute position detection device.
  • An advantage of the invention results from the simple arrangement of commercial components to realize a measuring device that realizes a distance control or a combined distance and speed control and / or determines a position of an elevator car relative to the road.
  • a further advantage lies in the automatic determination of the distance by the receiver and the triggering of an autonomous reaction in case of undesired approach of an elevator car to a roadway end or to an adjacent elevator car.
  • the receiver in conjunction with a local computing unit, the receiver is able to trigger a collision-preventing reaction based on speed information with a small amount of computation.
