Definitions

  • the invention relates to an electronic device for regulation of functions of hydraulic and electric elevators the preamble of claim 1.
  • Another disadvantage is that the controller is not recognizes the position of the cabin at all times.
  • the control must e.g. from the number of proximity switches run over or position cams on which floor the cabin is located or - during the journey - between which floors. This information is available in the event of a power failure lost. A reference run is necessary.
  • the other possibility the coding of the individual floors is not only complex, but also only helps to a limited extent, since at least one floor first must be approached to a new determination of the position to obtain.
  • Speed profiles and delays with the ramp times are in principle fixed with these systems and are also determined by the customer. This means that if the speed is to be changed, also made an adjustment to the settings of the switches become. There is only a basic division into two different speed ranges in which high transport and in the small positioning speed.
  • the known devices have a separate control part (e.g. also in the form of a PLC), which monitors all inputs and activates the outputs. Will continue partly in this control part or independently of it Floor logic implemented. This is for storage and processing the driving requirements in a certain order and represents a further additional effort e.g. also in In terms of wiring.
  • a separate control part e.g. also in the form of a PLC
  • a device which has a device in Form of a hydraulic elevator describes.
  • Execution enables a very extensive and cost-reducing Standardization and preparation for the installation of the system already during production. Costly and error prone on-site work is significantly reduced.
  • the disadvantage this system remains the same as that described above Institutions. Control of the system with processing the signals and the floor logic are also responsible here required control part in the form of a PLC.
  • the invention has for its object the generic device to train so that a continuous in a structurally simple manner and constant determination of the current position the elevator car is given.
  • the current position the elevator car is determined continuously and constantly.
  • Position control allows the position of the elevator car to be reliable determine, regardless of the proximity switches on each floor.
  • the elevator car can be on any desired Level to be stopped.
  • Based on the position detection and the position control are in turn safety-promoting surveillance the elevator journey and individual and flexible speed profiles enables more effective use of the elevators.
  • the device 1 by a connection 2 via a serial interface 3 in this case with an absolute encoder 4 connected. He sits on a shaft 5 of a pulley wheel 6 and is thus driven directly. About the pulley wheel 6 is deflected a rope 7 which e.g. for a mechanical (not shown) Braking device of an elevator car 8 is required.
  • the Resolution of the absolute encoder 4 and the diameter of the pulley wheel 6 determine the ratio of a transmitted information unit to the distance covered 9 of the elevator car 8, whereby the facility 1 after announcement of the boundary conditions these determine the current actual position 10 of the elevator car 8 can.
  • the movement profile 16 calculated internally in the device 1 as s-t diagram (Fig. 5) is used in the device 1 as a default the current target position 17 at any time x during the Elevator ride.
  • This target position 17 at the output of a profile generator 14 is present, a display 18 of the target position is fed, in the advantageously directly the desired position either in the physical unit m or e.g. also as floor display can be done. From this display 18 the target signal goes to one Summation point w-x 19. At this summation point 19 the Comparison with the current position xt of the elevator car 8.
  • consequential signal becomes the actual position xt 10 subtracted from the target position 17, which is shown in FIG Minus sign 21 is specified.
  • the target-actual comparison leads to a Control deviation E12, i.e. the difference between the target target position 17 and the current actual position 10 goes into a following arranged controller 20.
  • the output signal 22 of the controller 20 depends on its setting or the one implemented in the controller Gain and goes over adaptation elements 23 for signal conditioning. In the exemplary embodiment, this signal is by means of analog interface 24 as a signal to a frequency converter 25 passed. It controls an electric motor 26 (FIG. 1) more adequately Size to which a pump 27 is coupled. With the changeable Output signal 22 of the controller 20 is via the frequency converter 25, the motor 26 and the pump 27 the speed 28 of the elevator car 8 set, always depending on the profile and the results of the control difference formation and the controller gain.
  • the speed 28 of the elevator car 8 initially increases accordingly the calculated target profile of the speed-time curve 15 until the transport speed 29 is reached or up to Initiation of a braking phase 30 in which the speed again decreases.
  • the device 1 controls directly electrically operated valves 31 (Fig. 1) in a control block 32 one Hydraulic device and thereby gives the necessary flow paths free for the hydraulic medium. As soon as the target position reaches 18 the valves 31 are automatically activated by the device 1 switched off and the journey of the elevator car 8 stopped.
  • the detection of reaching the target position 18 or the desired one Floor levels are determined by a unit 33 inside the device 1 realized.
  • the unit 33 has at least one Comparator 34 (Fig. 3).
  • the comparator 34 By parameterizing the comparator 34 the behavior and accuracy of positioning can vary become.
  • the setting can also of the controller 20 are used to determine the behavior of the Elevator car 8 during acceleration 35 or braking 30 to influence (Fig. 5).
  • This cabin load measurement by means of the pressure sensor 36 is used e.g. also to prevent elevator travel when the load is in the Cabin goes beyond the permissible dimension. An intervention can also take place in the sequence of the floor logic take place and when a Limit load only cause elevator journeys, which no additional would bring load suspension. In this case, external Driving requests ignored.
  • Additional safety devices are in during an elevator journey device 1 activated. These are in the form of comparators 34 realizes and draw current values for comparison with defined ones Limits. For example, a so-called tracking error monitoring 33 provided.
  • the difference signal 12 between the current position 10 and the target position specified by the profile 17 compared with the setpoint or limit value in the comparator 34. If the following error 12 exceeds the limit or below, there is an error.
  • the comparator 34 outputs an output signal which leads to a shutdown of the system.
  • Monitoring provides additional security protection the device 1 with respect to the direction of travel 39 of the elevator car 8.
  • a protection unit 39 is provided for this purpose, with which the difference between the actual position 10 and the target position 17 is formed and is compared with the target value, that of the desired direction of travel equivalent. If the selected direction of travel, which is from the difference 12 between the actual position 10 and the target position 17 results automatically, not with the currently determined direction of travel corresponds, the protection unit 39 generates a signal that is used to stop the elevator car 8 instantaneously.
  • Secondary signals 40 can be connected to the device 1 e.g. the fire department key switches.
  • a logic unit 41 which is part of a microprocessor 42 (Fig. 2) is the logical control links like a PLC.
  • HW blocks 43 are on the microprocessor 42 for digital inputs 44 and digital outputs 45 connected for example with a control panel, with floor control buttons, with safety switches and the like, with secondary signals and the like can be connected.
  • valves 52, a load sensor 53, a frequency converter 54, a position sensor 55 and the like to the microprocessor 42 can be connected to which also a power supply 56 is connected.
  • external signals are used to reduce the amount of wiring collected via a bus system 47 and forwarded to the device 1.
  • the device 1 can both inside the elevator car 8 and be housed externally in a control room. Depending on the type of accommodation either the internal signals of the floor selection led out from the cabin keyboard, or at Housing the device 8 within the cabin, the signals the floor request from the outside of the device 1. This is preferably done to reduce the amount of wiring also by means of a bus system 47.
