Definitions

  • the invention relates to a method, a device for starting up an elevator installation and an elevator installation with this device according to the independent patent claims.
  • Elevator systems are provided with monitoring devices or safety circuits. These safety circuits typically consist of serially connected safety elements. For example, these security elements can monitor the condition of manhole or car doors.
  • Electromechanical safety circuits or bus-based safety circuits are known. The safe operation of such safety circuits is checked regularly. Safety circuits and test methods of such circuits are for example EP 1159218 A1 .
  • WO 2010/097404 A1 or WO 2013/020806 A1 known. However, it is not clear from this prior art whether or to what extent the safety during the commissioning of elevator systems is ensured.
  • a method and a device for starting up a lift installation according to the prior art is known from EP1795481 A1 known.
  • An elevator system includes a control unit, a bus, a plurality of bus nodes connected to the control unit via the bus, and a plurality of security state detecting means connected to the control unit via a bus node.
  • a control unit is understood here a unit that has at least a microprocessor, a memory and a memory. Such a control unit is therefore designed to execute computer-aided programs.
  • the control unit is configured here as a safety control unit, which monitors safety-relevant states of the elevator installation and, when an unsafe condition occurs, brings the elevator installation back into a safe state. This includes, for example, the Monitoring the shaft door conditions, wherein the elevator system is shut down when a shaft door is open and when no elevator car is on the shaft door associated floor.
  • a safety state detection means are understood here sensors or switching contacts that monitor a safety-related condition of the elevator system. This includes both position, speed or acceleration sensors that monitor a state of motion of an elevator car as well as switch contacts that monitor a manhole or cabin door state or the passing of a permissible end position by the elevator car. This listing is not exhaustive.
  • control unit for example, records all safety-state detection means connected to the bus and compares them with a stored expectation.
  • security condition detection means may be entered manually by an installation engineer into the control unit.
  • step A) there is a verified inventory of all security state detection means connected to the bus by the comparison or the manual input.
  • the control unit When checking the functionality of the connected safety-state detection means, the control unit virtually or really brings about a change of state of the elevator installation and checks whether the signals output by the safety-state detection means correspond to the state change. For example, the control unit causes the elevator car to move to a specific floor. This can be provoked on reaching the specific floor opening the shaft door. With proper functioning of the safety state detection means, which monitors the state of the shaft door, this transmits a signal indicating the open state of the landing door to the control unit. Alternatively, the control unit can virtually simulate a process of the elevator car to a specific embroidery work. The control unit accordingly proceeds for all safety-state detection means to be checked. If the transmitted signals transmitted by the security state detection means coincide with the expectation of the control unit, then step B) is concluded as being positive.
  • step C When checking the safety functions of the elevator system, the control unit goes one step further and brings about an impermissible state. This invalid state can be generated both virtually and real.
  • an impermissible state not only the signals transmitted by the security state detection means must correspond to the expectation of the control unit, but a reaction corresponding to the inadmissible state for transferring the elevator installation to a safe state must also be detected. For example, emergency braking by the control unit would have to be triggered when the elevator car is open when the shaft doors are open. If a corresponding reaction has been registered for all conceivable inadmissible states, then step C) is concluded as positive.
  • the elevator system can be released for normal operation.
  • the control unit changes from an unsecured state to a secure state.
  • the control unit can be configured. If the control unit assumes the secured state, a configuration of the control unit is excluded. In this secured state the control unit can only be brought into different operating modes. These operating modes include at least a normal operating mode and a maintenance mode.
  • the controller may also include an inspection mode, an evacuation mode or other special operating modes.
  • An advantage of the method according to the invention is that the transition from commissioning to normal operating mode is defined by means of the control unit. Steps A) to C) require clear conditions that must be met before the elevator installation can be set to normal operation mode. Thus, the elevator system can be safely put into operation.
  • the elevator system has an emergency brake for braking an elevator car.
  • the emergency brake is designed for example as a drive brake, which counteracts a rotational movement of the drive axle of the drive.
  • the braking effect of the drive brake is transmitted from the drive axle via a traction sheave and a suspension means to the elevator car.
  • the emergency brake can be triggered by the control unit.
  • the examination of the safety functions in step C) includes a release of the emergency brake due to an impermissible state of motion of the elevator car and / or an impermissible state of the car or shaft doors.
  • the emergency brake due to an impermissible speed, an unintentional movement of the elevator car in the open state of the shaft doors, overrunning a limit switch, an impermissible acceleration, a Inadmissible open state of the shaft door or an inadmissible open state of the cabin doors triggered.
  • the elevator system has a catch brake for braking the elevator car.
  • the safety brake is arranged on the elevator car and acts on a guide rail of the elevator car to bring the elevator car to a standstill.
  • the safety brake can also be triggered by the control unit.
  • the examination of the safety functions in step C) comprises a triggering of the safety brake due to an impermissible state of motion of the elevator car and / or an impermissible state of the car or shaft doors.
  • the safety brake is triggered due to impermissible speed, unintentional movement of the elevator car when the shaft doors are open, overrunning a limit switch, improper acceleration, improper open status of the hoistway door, or inadmissible open state of the car doors.
  • the impermissible state of motion of the elevator car and / or the impermissible state of the car or the shaft door are generated virtually by the control unit, by the control unit transmitting at least one error signal to a bus node.
  • the unacceptable state of motion of the elevator car and / or the inadmissible state of the car or shaft door are generated by the control unit by bringing the elevator car and / or the car or the shaft door by the control unit in an inadmissible state of motion or an inadmissible state ,
  • the elevator system has an interface for inputting control commands to the control unit.
  • the interface can be designed as a key board or as a touch-sensitive screen, via which a control command or a code in the form of a combination of numbers and / or a sequence of letters can be entered.
  • the input of configuration commands to the interface is accepted only in the unsecured state of the control unit, on the other hand, the input of configuration commands to the interface in the secure state is rejected by the control unit.
  • Configuration commands here are commands to the control unit with which the number of bus nodes and / or the type of state detection means can be detected.
  • control unit In the secured mode, preferably only predetermined operating modes are enabled by the control unit, which include a normal mode, a maintenance mode or an inspection mode.
  • Another aspect of the invention relates to a device for carrying out the method and an elevator installation with the said device.
  • the in the Fig. 1 schematically illustrated elevator installation 1 comprises a control unit 2, which is connected via a bus 3 to a plurality of bus nodes 41 to 48 and 49a, 49b.

  • the respective bus nodes 41, 42 or 43 are each assigned a security status means, here for example a switching contact 61a, 62a, 63a, which records information relating to the state of the associated shaft door 61, 62 or 63 (open, closed, locked) and possibly a fault message for the control unit 2 can generate.
  • a security status means here for example a switching contact 61a, 62a, 63a, which records information relating to the state of the associated shaft door 61, 62 or 63 (open, closed, locked) and possibly a fault message for the control unit 2 can generate.
  • the elevator installation 1 furthermore has an elevator cage 7.
  • the elevator cage 7 is equipped with an elevator door 74, which is likewise assigned to a bus node 44.
  • the bus node 44 is a further security state means, such as another switch contact 74a assigned, which information regarding the state of the associated elevator door 74 (open, closed, locked) determines and possibly generate a fault message for the control unit 2.
  • the elevator installation 1 can furthermore have a bus node 45 and a bus node 46 which are each assigned to a catch brake 75 arranged in the elevator car 7 and an emergency switch 76.
  • the safety brake 75 is used for safety braking of the elevator car 7, for example, when reaching an overspeed of the same.
  • the elevator installation 1 can be brought to an immediate standstill in an emergency situation.
  • a drive unit is further arranged, which is equipped with an emergency brake 87 and a further safety state detection means, such as a speed sensor 88, each associated with a bus node 47 and 48.

  • node-specific data data about the bus node addresses or data of the state detection means connected to the bus node will become here.
  • the determined data are stored by the control unit.
  • the detected node-specific data are then automatically compared by means of the control unit 2 with a subscriber list 5, which is empty in this embodiment. For this reason, a request is made to a technician who is responsible for commissioning the elevator installation 1 for each determined bus node 41 to 48 and 49a, 49b, if the respective determined bus node 41 to 48 and 49a, 49b in the participant list should be saved or not.
  • the technician Upon confirmation of the determined bus node 41, the technician receives a new message for storing a further determined bus node, for example, the bus node 42. If canceled, the technician can restart the commissioning, or edit the list of participants.
  • the bus node 41 thus stored in the subscriber list 5 or the security state detection means 61 a connected thereto can then be tested for functionality in accordance with the method step B from the Fig. 2 be subjected.
  • the control unit 2 controls the landing door 61 and leaves it open.
  • the security state detection means 61a assigned to the bus node 41 detects the opening of the shaft door 61 and reports this change of state to the control unit 2. The reported state change thus tests the functionality of the bus node 41 and of the assigned security state detection means 61a.
  • the control unit 2 can, for example, also instruct the drive unit to move the elevator car 7 to the second floor.
  • the control unit 2 receives node-specific data about the rotational speed of the engine from the speed sensor 88 from the bus node 48, which characterize a movement of the elevator car 7.

  • control unit 2 simulates an actuation of the emergency switch 76 and determines whether the emergency brake 87 immediately brings the elevator car 7 to a standstill by means of a corresponding notification of node-specific data of the bus nodes 47 and 48.
  • control unit 2 can simulate the detection of an overspeed of the elevator car 7 by the speed sensor 88 and provoke triggering of the catch brake 75. Accordingly, a status message of the safety brake 75 is transmitted from the assigned bus node 45 to the control unit 2. In this case, the triggering of the safety brake 75 is confirmed.
