Definitions

  • the invention relates to an elevator with safety device, in particular with two safety controllers.
  • an elevator is equipped with a safety chain of series-connected contacts and switches.
  • the contacts or switches monitor the condition of a safety-related elevator component, such as a landing door or a car door, or determine a critical driving situation of the car, such as an overspeed or crossing a safety zone at the shaft end. If, in the event of an unsafe situation, one of these switches or contacts in the safety chain is open and thus the safety chain is interrupted, the power supply to the drive is interrupted and the elevator is shut down.
  • This electronic safety device has a safety controller and a safety bus.
  • the safety controller queries the status of electronic sensors connected to bus nodes to the safety bus via the safety bus. Since the bus nodes are uniquely addressable, the error source can be localized in the event of a fault.
  • the substitution of electro-mechanical switches by electronic components also makes the safety device more reliable.
  • EP 1159218 A1 The electronic security device according to EP 1159218 A1 is relatively expensive. Because the individual components, such as Sicherereitscontroller-, safety bus, bus node and connected safety switch and sensors, this safety device must be designed fail-safe.
  • the object of the present invention is to develop an electronic safety device for a lift, which is particularly favorable.
  • an elevator which has a cab, a drive arrangement, a first safety controller and a second safety controller.
  • the first and the second safety controller each monitor a state of the elevator by means of at least one first and second sensor. If the first and second safety controllers determine an unsafe condition, at least one of the first and second safety controllers takes action to bring the elevator to a safe state.
  • the first sensor is disposed on the cab and configured to detect a position and speed of the cab.
  • the second sensor is arranged in the region of the drive arrangement and designed to detect a position and speed of the elevator car by monitoring the rotational movement of a rotor of the drive arrangement.
  • the advantage of this elevator is the multiple detection of the position and speed of the car by the first and second sensors and the double evaluation of the sensor signals by the first and second safety sensors.
  • This continuous multiple design of the safety device allows the use of cheap standard components.
  • systems already present in the elevator such as the first and the second sensor, which already provide information about the position and speed of the car for an elevator control, are optimally utilized.
  • the first safety controller is arranged on the cabin and the second safety controller is arranged in the region of the drive arrangement. This results in short communication paths on the one hand between the first sensor and the first safety controller and on the other hand between the second sensor and the second safety controller.
  • Yet another aspect relates to detecting the opening condition of a hoistway door by means of a further third and a further fourth sensor.
  • the third sensor communicates with the first safety controller, preferably via an associated floor panel.
  • the fourth sensor communicates with the second safety controller.
  • Yet another aspect relates to the detection of an opening state of a car door by means of a further fifth and a further sixth sensor.
  • the sixth sensor communicates with the second safety controller, preferably via an associated cabin panel.
  • the fifth sensor communicates with the first safety controller.
  • the elevator car has a cab brake.
  • the first and / or the second safety controller actuate the cabin brake upon detection of an unsafe condition to bring the elevator to a safe state.
  • the drive assembly has a drive brake.
  • the drive brake is also actuated by the first and / or the second safety controller upon detection of an unsafe condition to bring the elevator in a safe state.
  • one aspect relates to a controller bus connecting the first and second security controllers.
  • the first and second safety controllers check the detected condition for equality. If the equality of the detected state deviates, the first and / or the second safety controller bring the elevator into a safe state.
  • the elevator has an elevator controller, wherein the first and second safety controllers of the elevator controller transmit a detected condition of the elevator.
  • a plurality of shaft doors 44 are provided on the floors and a car door 26 which release the car 20 at a floor stop for boarding or alighting and close again before a planned onward journey.
  • a door drive 25 is provided, which is arranged on the cab 20.
  • An elevator control 1 controls the travel of the car 20.
  • the elevator control 1 is connected via a line 42, in particular a data bus with floor panels 43, which are each positioned on a floor.
  • the floor panels 43 represent human / machine interfaces with which a passenger can enter a car call.
  • different information can be transmitted to the elevator control 1.
  • At least the location of the operated floor panel is notified to the elevator control 1.
  • the desired direction of travel or even the desired destination floor can be communicated with the car call.
  • the elevator 10 is equipped with a cabin panel 27, which is positioned in the interior of the cabin 20 and to which the elevator control 1 is connected via a further data line.
  • the data line is designed as a controller bus 4.
  • the cabin panel 27 also represents a human / machine interface with which a passenger of the elevator control 1 can enter his destination floor.
  • the cabin panel 27 may include controls for opening and closing the cabin door 26. If the floor panels 43, are designed so that the desired destination floor is already communicated during the car call, the controls for entering the destination floor on the cabin panel 27 can be omitted.
  • the elevator control 1 evaluates the incoming car calls and destination floor information and plans the trips of the car 20 to such an extent that the car calls as well as the desired destination floors are served or approached as efficiently as possible. Accordingly, the elevator controller 1 gives control commands to the power supply 33 to supply power to the motor 32 and the drive brake 31 to execute the scheduled trips of the car 20. Likewise, the elevator control 1 gives control commands to the door drive 25 to open and close the car door 26 and an associated shaft door 44 in the case of a floor stop. These control commands to the power supply 33 and the door drive 25 preferably take place via the controller bus 4.
  • the elevator control 1 is arranged in the area of the drive arrangement 30.
  • the elevator control 1 can also be positioned in another area of the elevator 10, for example on the cabin 20, in the context of a shaft door 44 or in the lower area of the shaft.
  • a safety device which monitors the condition of the elevator 1, intervenes upon detection of a critical condition and brings the elevator 1 into a safe condition.
  • the safety device has a first safety controller 2 and a second safety controller 3, which are connected via the controller bus 4 and can communicate via this.
  • the two safety controllers 2, 3 monitor in particular the position and the speed of the car 20, the state of the shaft doors 44 and the car door 26 each with a separate set of sensors 24, 34, 45, 46, 22, 23.
  • other sensors connectable to the security controllers 2, 3.
  • Such sensors may for example be designed to realize a limit switch at the end of the road, a slack rope monitoring or other safety-related functions of the elevator 10.
  • a first position and speed sensor 24 is disposed on the cab 20 and moves along the carriageway 20 therewith.
  • This sensor 24 is for example part of a system that detects an absolute position of the car 20 with respect to the road.
  • a system includes, for example, a magnetic tape that is laid along the roadway and a Hall sensor 24 that is mounted on the car and reads position information stored on the magnetic tape.
  • Other such systems, based on optical, dielectric, etc., codes are known and may be used as an alternative to the example above. Deviating from tape carriers, the coded information can also be applied directly to a guide rail or a wall of the shaft.
  • the first position and speed sensor 24 can also be implemented as an incremental encoder, which runs on a guide surface of a guide rail by way of a friction wheel.
  • the first position and speed sensor 24 is connected to the first safety controller 2 via a line and transmitted via signals that the first safety controller 2 evaluates.
  • a second position and speed sensor 34 is located in the area of the drive assembly 30 and monitors the direction of rotation and angular velocity of the drive shaft of the motor 32.
  • this position and speed sensor 34 is designed as an incremental encoder. This sensor design is reliable and cheap to obtain as a standard product. The person skilled in the art, of course, it is open to use other sensor designs, with the likewise from a movement of the engine, the position and speed of the cabin 20 can be derived.
  • the second position and speed sensor 34 is preferably connected to the second safety controller 3 via a further line and transmitted via signals that the second safety controller 2 evaluates.
  • a third and fourth sensor 45, 46 are provided which each monitor the opening state of an associated hoistway door 44.
  • each shaft door 44 is monitored by such a pair of sensors 45, 46.
  • sensors 45, 46 are designed as electro-mechanical switches.
  • other sensor types can be used to monitor the opening state of a hoistway door 44.
  • Such alternative sensors are based, for example, on electromagnetic, optical or magnetic functions.
  • the third sensor 45 is connected to the floor panel 43.
  • the signals of the third sensor 45 are transmitted via a line 42, with the floor panel 43 is connected to the elevator control 1, via elevator control 1 and controller bus 4 to the first safety controller 2 and evaluated there.
  • the fourth sensor 46 transmits its signals via a line 41 directly to the second safety controller 3.
  • the second safety controller 3 evaluates the signals of the fourth sensor 46.
  • all fourth sensors 46 of different shaft doors 43 are connected in series.
  • the lines 42 and 41 are preferably designed as a data bus.
  • a fifth and sixth sensor 22, 23 monitor the opening state of the car door 26. These sensors 22, 23 are typically designed as electro-mechanical switch. Like the third and fourth sensors 45, 46, the fifth and sixth sensors 22, 23 are also feasible by comparable sensors based on alternative modes of operation.
  • the fifth sensor 22 is connected directly to the first safety controller 2 via a line.
  • the first safety controller 2 evaluates the incoming signals of the fifth sensor 22.
  • the sixth sensor 23 is connected to the cabin panel 27. Accordingly, the signals of the sixth sensor 23 via the controller bus 4, to which the cabin panel 27 is connected, transmitted to the second safety controller 3 and evaluated there.

  • the two safety controllers 2, 3 also compare the checked sensor signals for equality. If an inadmissible state or deviation from the equality of the incoming sensor signals from at least one of the safety controllers 2, 3 is detected, the at least one safety controller 2, 3 takes measures to bring the elevator 10 into a safe state.
  • An unsafe condition occurs, for example, when a hoistway door 43 is open, although the car 20 does not rest on the corresponding floor, or when a car door 26 is not closed during travel of the car 20.
