Definitions

  • the invention relates to a security monitoring device for a Elevator car.
  • a device for delay control intended.
  • the elevator shaft are located at the top of the pit and on the mechanical side Buffers that serve to decelerate the elevator car in an emergency.
  • the speed of the elevator car a does not exceed the predetermined limit.
  • the Braking device for the elevator car when the limit exceeded will be started soon enough for a sufficient deceleration, the takes place in accordance with a braking ramp, it can be done so that the buffer the Residual braking can take over.
  • the device arranged for delay control at the appropriate location in the shaft electromechanical switch comprising, with a safety relay module coupled, and when they are reached in an elevator ride in the direction of Buffer and exceeding the limit for the speed Cab brakes triggered and simultaneously the drive is turned off.
  • a device for retracting and if necessary to provide readjustments with open doors with a Bridging device for electromechanical door contacts that monitor whether the shaft door is closed.
  • a Bridging device for electromechanical door contacts that monitor whether the shaft door is closed.
  • Such mechanically based safety devices do not allow any continuous monitoring, but only a one-off.
  • EP 0 694 792 B1 and EP 1 030 190 B1 is a Device for detecting the position of an elevator car is known, wherein in the Elevator shaft a sound signal conductor with predetermined, uniform Sound propagation speed is while the elevator car a Signal coupler for coupling a clocked sound signal in the Having sound signal conductor. At both ends of the sound signal conductor are Signal output coupler arranged with an evaluation unit for determining the Duration difference of the coupled-in sound signal from the coupling point to the signal extractors and for generating a for the current position of the Elevator car in the elevator shaft representative signal are connected.
  • the object of the invention is to provide a security monitoring device for to create an elevator car that provides continuous safety monitoring allows.
  • Fig. 1 shows a block diagram of an elevator monitoring and control with a position detection device for an elevator car.
  • FIG. 2 shows a block diagram of a security monitoring device for the elevator control of Fig. 1.
  • Fig. 3 shows a velocity-time diagram as a motion profile for a Elevator car.
  • a Position detection device for one along an elevator shaft A means a traction drive D movable elevator car 1 is the latter with a Signal coupler 2 provided, which serves to sound signals in a Sound signal conductor 3 with predetermined, uniform Sound propagation speed, which along the Elevator shaft extends. In both end regions of the sound signal conductor. 3 There is in each case a receiver unit 4a or 4b, which has a signal output coupler 5 and an evaluation unit 6 include. One of the evaluation units 6 supplies Trigger signals corresponding to a predetermined time grid to the signal coupler 2 of the elevator car 1, which is the coupling of a sound signal in the sound signal conductor 3 trigger, and to the other evaluation unit 6, so this also knows the respective triggering time.
  • the signal coupler 2 both Evaluation 6 tell the time of coupling the sound signal, so that both evaluation units 6 each separately from the predetermined, uniform sound propagation velocity and signal transit time the Can calculate the position of the elevator car 1.
  • the outputs 7a, 7b of the evaluation units 6 serve as inputs for a Safety monitoring device 8.
  • the latter communicates with a Elevator control 9, via which the driving profile of the elevator car 1 is predetermined, and a safety circuit 10 for shutting off the elevator drive.
  • the safety monitoring device 8 comprises two bushes 11, with to which the outputs 7a, 7b of the evaluation units 6 are connected. About one Interface 12, the position signals of the evaluation units 6, the corresponding the trigger signals are supplied in a predetermined time frame, respectively a microprocessor 13 a and 13 b given, for each one Power supply unit 14 is provided. The latter are connected to a network and connected to an emergency battery power supply 15 connected. At this dual-channel security monitoring, the microprocessors 13a communicate 13b for the purpose of mutual control over a line 16 with each other, whereby a crosswise data comparison, which also synchronizes the two Microprocessors 13a, 13b can be used.
  • microprocessors 13a, 13b can be speed and acceleration and optionally one jerky movement of the elevator car 1 location dependent notice and currently compare with a given motion profile.
  • an amplifier 18, which may also simultaneously as Comparator can act only to from both microprocessors 13a, 13b Maschinenminalten be present, the same output signals to be driven, the a safety relay stage 19 is actuated, the - in response to the microprocessors 13a, 13b - on the elevator control 9 and the safety circuit 10th acting with an appropriate jack 20 of the Safety monitoring device 8 is connected.
  • Microprocessor 13a and 13b may optionally also have two interfaces 12 be provided to receive signals from different types of encoders to be able to process.
  • a curve K1 is shown by way of example, which represents the driving profile of an elevator car 1 between two further floors, which is predetermined by the elevator control 9.
  • the curve K1 has at the time of departure starting from a starting ramp up to a rated speed v nenn and from the latter to the arrival time a braking ramp.
  • the curve K2, also shown by way of example in FIG. 3, is the driving profile between two closely adjacent storeys, the nominal speed vnom not being reached.
  • the microprocessors 13a, 13b simultaneously or within a time window emit a corresponding signal which causes the traction drive to stop via the safety relay stage 19.
  • a device for limiting the speed of the elevator car 1 is formed, which not only reacts to a predetermined exceeding of vnenn , but is a speed profile and thus more responsive.
  • the safety monitoring device 8 can be used at the same time as a device for deceleration control, by then, if it is determined at a certain point in the elevator shaft A, that the current speed of the elevator car 1 a predetermined amount (not necessarily V nominal) exceeds, so that braking is no longer ensured by located in the elevator shaft a buffer, the microprocessors 13a, 13b leave the same time or within a time window, a corresponding signal to the safety relay stage 19 a stopping of the Travel drive and triggering the braking device causes. - As a result, smaller sized buffer can be used, or you can completely do without it.
  • the security monitoring device 8 as a control for retractable with open doors usable.
  • a request signal of a user are present from the elevator car 1 or from the corresponding floor, about via a socket 21 of the safety monitoring device 8 and an interface 22 is given to the microprocessors 13a, 13b. If the request signal arrives too late because the user has pressed the corresponding button too late, the speed is too high and the microprocessors 13a, 13b are not giving Bridging signal for the door contacts off, so that the doors open either can not be started before the standstill of the elevator car 1 or the Elevator car 1 even passes through.
  • the security monitoring device 8 also for Creation of a virtual shelter on the head and / or pit side elevator shaft A, for example, when carrying out work in this Be used area, i. that at a corresponding request signal the route of the elevator car 1 is limited accordingly, so that a Intrusion into the virtual shelter is prevented.
  • microprocessors 13a, 13b can also be used in Reference to the acceleration and the derivative thereof (the latter for evaluation of jerky movements).
  • a diagnostic LED display 23 may be connected to the microprocessors 13a, 13b be coupled.
  • the safety relay 19 can also have its own Power supply unit 24, in turn, from the microprocessors 13a, 13b is monitored.
  • the respective position of the elevator car 1 is either from the position detection device via a line 25 or one of the Microprocessors 13 a, 13 b transmitted to the elevator controller 9.
  • Over a Input device 26 in the form of a keyboard or the like. can the microprocessors 13a, 13b required data are entered. However, the data can also are received via the line 25 from the elevator controller 9.
  • an output 28 may be present, which is the bottom flush of elevator car 1 and floor displays.
