Definitions

  • the invention relates to an electronic security system for a lift according to the preamble of claim 1.
  • an electronic security system for an elevator in which a safety circuit is performed when an unsafe condition is detected.
  • the electronic security system includes a security controller and a communications bus that facilitates exchange of control and data signals between a microprocessor-based controller and various components including bus nodes.
  • the bus nodes are designed to provide an interface for sensors, contacts and switches.
  • a security controller processes the messages received from the bus nodes Data and determines if an unsafe condition exists. In an unsafe condition, the safety controller sends a stop signal to the drive and brake unit of the elevator, and in addition, a status signal indicating the unsafe condition is sent to the controller.
  • the controller of the elevator should not process information of the bus node, but the controller already receives the processed information of the bus node from the safety controller to allow a faster response of the control device of the elevator.
  • the safety control device alone takes over the safety tasks and it has an elementary role.
  • the object of the invention is to obtain a fast and secure embodiment of an electronic security system according to the preamble of claim 1, in which a relief of a security component takes place, giving access to more information (s) and increased security in the event of possible improvement in maintenance Episode has.
  • a safety component such as a safety controller is relieved by the control of the elevator is not currently receiving the message from the safety controller that a shutdown or a transfer is made in a safe state at a potential risk potential or was.
  • Fig. 1 shows a block diagram for an elevator. It is provided a controller 1 for a designated 2 schematically illustrated elevator car.
  • a motor 21 for driving the elevator car 2 is coupled to a bus 3 via a frequency converter 20.
  • the controller 1 communicates the bus 3 by means of bus nodes with components which are exemplified as a floor switch 4, door contact 5, command transmitter 6 and safe actuator 7 for a door motor 8 of the elevator car 2.
  • the controller 1 receives, via the bus 3, via the bus nodes, which form an interface for the components, signals of the components, such as the request for a trip to a certain floor via the commander 6 in the elevator car 2.
  • the door contacts 5 provide a signal as to whether the door of the corresponding floor is closed or open.
  • the door contact 5 ' provides a signal as to whether the door of the elevator car 2 is closed or opened.
  • the safe actuator 7 is used to drive the door motor 8 of the elevator car 2, which can be controlled by the controller 1 via corresponding signals that are sent via the bus 3.
  • U ltra s chall- P ositionssysteme or USP systems are 9 or a two-channel system USP provided, which detect in each case via ultrasound the position of the elevator car 2 in the elevator shaft.
  • Systems USS Schmersal are preferably used as USP systems 9, the function of which is described in the product catalog "Elevator Switching Systems - Elevator Positioning System USP" of 31.10.2007.
  • the two USP systems 9 or the one two-channel USP system is a redundant determination of the position possible, which meets high security requirements by the two USP systems 9 or by the two-channel USP system determined position of the elevator car 2 is compared.
  • the speed of the elevator car 2 in the elevator shaft can be determined via the time determined position of the elevator car 2 by the two USP systems 9 or a two-channel USP system as a derivation of the location function of the elevator car 2 in the elevator shaft after the time.
  • multiple USP systems 9 may also be used as two. With two, however, the required redundancy already results. Analogously, the redundancy is also ensured with a two-channel USP system.
  • a transmitter having two receivers and corresponding two channels may be used.
  • a safety controller 10 is coupled as Can Safety Controller, which can receive the signals from floor switch 4, door contact 5, 5 ', command transmitter 6, safe actuator 7, door motor 8 and USP system 9 via the bus 3.
  • the floor switch 4, door contact 5, 5 ', command 6, safe actuator 7, and USP system 9 can be referred to as sensors.
  • the controller 1 is connected to a safety circuit 11, which the safety controller 10 can open via a (safety) switch 12.
  • the safety controller 10 monitors the safety function of the elevator. If the security controller 10 determines an unsafe condition, such as the door contact 5 'indicates that the door of the elevator car 2 is open during travel between two floors, the (security) switch 12 is opened and the elevator is disabled or in a safe state. The opening of the safety circuit 11 leads to the operation of the (safety) switch 22, which shuts off the motor 21.
  • a device 13 for monitoring the speed of the elevator car 2 can open a (safety) switch 14 independently of the safety controller 10 in order to access the safety circuit 11 open when, for example, a predetermined threshold speed of the elevator car 2 is exceeded.
  • the device 13 for monitoring the speed of the elevator car 2 can be implemented independently of, or by, the USP systems 9.
  • one or two limit switches 15 for monitoring the exceeding of a predetermined spatial position of the elevator car 2 can open a (safety) switch 16 independently of the safety controller 10 in order to open the safety circuit 11, for example when the elevator car 2 in the elevator shaft exceeds a predetermined end position at the lower or upper end of the elevator shaft.
  • the limit switch (s) 15 may be implemented independently of, or through the USP systems 9 or the two-channel USP system.
  • the controller 1 receives the feedback from the safety circuit 11 that the safety circuit 11 has been opened and the (safety) switch 22 has been actuated to stop the motor 21.
  • a means is provided that the controller 1 reports the open safety circuit 11. This means can be realized, for example, by the (safety) switch 22.
  • the controller 3 the information of the components, such as floor switch 4, door contact 5, command transmitter 6, safe actuator 7, door motor 8 and USP system 9, evaluates and determines that a shutdown by the safety controller 11 must be made (te). It can also be provided that the safety controller 11 forwards the signals received from the components to the controller 1.
  • the controller 1 can provide improved diagnostics and maintenance by evaluating the signals of the individual components connected to the bus nodes.
  • the safety controller 10 can redundantly determine the position of the elevator car 2 in the elevator shaft through the two USP systems 9 connected to the bus 3 or through the two-channel USP system.
  • redundant speed information of the elevator car 2 can be determined by the safety controller 10 from the two USP systems 9 or the one dual-channel USP system, so that a "retrieval" in the area of the door zones of the elevator car 2 can take place, i.
  • the safety controller 10 gives the safe actuator 7 on the elevator car 2 an enable signal, so that the door motor 8 may be actuated in the area of the door zone.
  • the function of the door zone monitoring in the safety controller 10 can be integrated.
