Definitions

  • the present invention relates to an elevator installation with a sensor for detecting vibrations and to a method for operating such an elevator installation according to the subject matter of the patent claims.
  • An elevator system has moving mechanical components, such as a drive, cabin and shaft doors, car door drive, a car door closing mechanism, guide rollers, or guide shoes, whose proper functioning is to be ensured.
  • the individual components are maintained and maintained at regular intervals.
  • the cost of such maintenance is relatively inefficient, since the maintenance intervals are fixed and do not depend on the effective wear of a concrete elevator system and its components.
  • a reliable indication of the degree of wear of a moving mechanical component is the degree of vibration. In normal permissible operation, a certain degree of vibration is not exceeded. As wear on a component progresses, the vibrations increase noticeably. If a predeterminable degree of vibration is exceeded, the time has come to repair or replace the component.
  • Vibrations propagate as sound or structure-borne sound waves and can be detected by means of a sensor.
  • sound waves here are waves that propagate in a gaseous medium such as air
  • structure-borne sound waves here are waves that propagate in a solid medium such as steel or iron.
  • sensors that are designed as microphones, accelerometers or voltage measuring sensors are suitable.
  • An evaluation circuit is connected to one or more sensors. The evaluation circuit and at least one associated sensor form a monitoring unit.
  • the evaluation circuit has a processor with which the evaluation circuit evaluates the recorded sound or structure-borne sound waves.
  • the recorded sound or sound Structure-borne sound waves can be evaluated in terms of their amplitude and frequency in the evaluation circuit and compared with a predetermined value.
  • Another unsolved problem is the upgrading of an existing elevator system with a monitoring unit. Because the existing elevator control of the elevator system is not intended to evaluate information of the monitoring unit or even state information, such as operating condition of the elevator system, speed or position of the cabin, the monitoring unit. Also to this problem statement expresses itself WO 2009/126140 A1 Not.
  • an existing elevator system should be easy to retrofit with a monitoring unit for monitoring the components.
  • the task is solved with a lift system that uses a sensor and an evaluation circuit features.
  • vibrations can be detected with the sensor, which are generated during operation of the elevator installation.
  • the evaluation circuit is connected to the sensor.
  • the vibrations detected by the sensor can be evaluated by the evaluation circuit.
  • the elevator system is characterized in that by means of the evaluation circuit, the detected vibrations are comparable with a predefinable operating value and a predefinable threshold value.
  • the operating value represents a value of vibrations which occur in a permissible normal operation of the elevator installation.
  • the threshold represents a value of vibration that is inadmissible.
  • the vibrations generated are in a characteristic frequency range and / or amplitude range. With continuous wear and aging of the components, this frequency range or amplitude range changes accordingly. These changes in the vibration behavior can be detected by sound or structure-borne sound waves through the sensor.
  • the vibrations are recorded as sound or structure-borne sound waves from the sensor, forwarded to the evaluation circuit and evaluated there spectrally. This means that the vibrations are evaluated in terms of amplitude and frequency.
  • the vibrations evaluated in this way are compared with the operating value and the threshold value.
  • the operating value represents a vibration value, as it usually occurs during normal operation of the elevator system.
  • the threshold represents an impermissible vibration value, which indicates a malfunction or excessive wear of a component.
  • the evaluation circuit has at least one processor which performs the spectral analysis and the value comparison and a memory unit in which the operating value and the threshold value are stored.
  • An advantage of this two-stage value comparison lies in the determination of the operating value. Because it is detectable without feedback from the elevator control, whether the elevator system is in operation or is still. This is particularly advantageous for retrofits of elevator systems. Thus, for example, the evaluation during the standstill of the elevator system decide independently, if not required components of the monitoring unit can be set in a stand-by mode and only then to awaken from stand-by mode when the evaluation determines an operating value.
  • a quality value can be calculated by means of the evaluation circuit from the comparison of the vibrations with the operating value and the threshold value.
  • the quality value is calculated as the ratio between the time duration in which the threshold value is reached or exceeded and the time duration in which the operating value is reached or exceeded.
  • the evaluation circuit compares this quality value with a predefinable critical quality value.
  • the critical quality value is preferably stored in the memory unit. If the critical quality value is reached or exceeded, a responsibility alert can be triggered.
  • the state change alarm indicates that at least one component of the monitored elevator system is to be replaced or repaired.
  • a state change alarm can be triggered.
  • the evaluation circuit can now be configured so that if it does not receive vibration signals from an associated sensor for a period of about 8, 14, or more hours, it triggers a state change alarm.
  • the cause of the trip namely the failure of the sensor or the interruption of a connection to the sensor, can be communicated, which simplifies the location of the fault for a service technician.
  • the evaluation unit has a time indication unit.
  • the evaluation circuit the time to trigger a state change alarm due to a lack of the operating value depending on the time of day and / or day specify.
  • a state change alarm can be triggered even if the operating value falls below at least one hour.
  • the triggering of a state change alarm can only take place after several weeks, since the elevator system can be idle for a long time, for example, during the summer holidays.
  • a still further aspect relates to the setting of the operating value by means of a learning run of the elevator installation.
  • This learning run is performed after the installation of the evaluation circuit and the associated sensor.
  • the sensor absorbs the vibrations generated during this learning run and the evaluation circuit stores these vibrations as an operating value on the memory unit.
  • An advantage of detecting the operating value by means of a learning run is that always the same monitoring unit consisting of sensor and evaluation circuit can be installed independently of the type of elevator installation. This reduces the coordination effort when configuring and ordering a monitoring unit. In addition, a mounting of a monitoring unit with incorrectly stored operating value is excluded. Alternatively, the operating value can be stored beforehand on the memory unit of the evaluation circuit as a function of the type of elevator installation. The learning journey can be omitted.
  • the evaluation circuit preferably calculates the threshold value after acquisition of the operating value by means of a learning run.
  • the operating value serves as the starting point.
  • the amplitudes of the frequencies recorded in the spectral analysis for the operating value are multiplied by a predefinable factor.
  • the calculated threshold value is stored on the memory unit.
  • the threshold value can be stored beforehand on the memory unit of the evaluation formwork as a function of the type of elevator installation.
  • the elevator installation in the case of a state change alarm, is provided for maintenance work.
  • a service technician is notified to service the elevator system. This increases the efficiency of the maintenance work. This is because maintenance work is only carried out when a component is actually to be repaired or replaced.
  • Fig. 1 shows an elevator system 10.
  • This elevator system has a car 1, a counterweight 2, a support and propellant 3, in which the car 1 and the counterweight 3 are suspended in a 2: 1 ratio and a pulley 5.1.
  • the traction sheave is 5.1 with a in the Fig. 1 for clarity, not shown Drive unit coupled and is in operative contact with the support and propellant 3rd
  • the car 1 and the counterweight 2 are movable by means of a rotational movement of the traction sheave 5.1, which transmits a drive torque of the drive unit to the support and propellant means 3 substantially along vertically oriented guide rails.
  • the guide rails in the Fig. 1 not shown.
  • the car 1 and the counterweight 2 are guided by means of guide elements, such as guide shoes or guide rollers on the guide rails.

  • the counterweight 2 is suspended by means of a bearing 4.1 on the first loop.
  • the counterweight 2 is coupled to the bearing 4.1.

  • the carrying and / or propellant 3 wraps around the counterweight carrying roller 4 by approximately 180 ° and then extends upwards to the first deflecting roller 5.2.
  • the cabin 1 is suspended in a second loop of the carrying and / or propellant 3.
  • the second loop is formed by a part of the carrying and / or propellant, which lies between a second end 3.1 of the support and / or propellant 3 and a second traction sheave 5.1.
  • the cabin 1 is suspended by means of two cabin carrying rollers 7.1, 7.2 on the second loop.
  • the carrying and / or propellant 3 extends from a second fixed point, to which the second end 3.1 of the carrying and / or propellant is attached, down to a first cabin roller 7.1.
  • the carrying and / or propellant 3 wraps around the first cabin roll 7.1 by approximately 90 °, then extends substantially horizontally to a second cabin roll 7.2 and umschling the second cabin roll 7.2 by approximately 90 °. Furthermore, the carrying and / or propellant 3 extends upward to the traction sheave 5.1. From the traction sheave 5.1, the carrying and / or propellant 3 finally extends to the first guide pulley 5.2.
  • the two fixed points at which the first and second ends 3.2, 3.1 of the carrying and / or propellant 3 are attached, the guide pulley 5.2, the traction sheave 5.1, and the guide rails of the car 1 and the counterweight 2 are directly or indirectly to a supporting structure, typically shaft walls, coupled.
  • the first end 3.2 of the carrying and / or propellant 3 is coupled to a sensor 8.
  • the sensor 8 detects structure-borne sound waves, which transmits the carrying and / or propellant 3 thereto.
  • the senor 8 is coupled to a guide rail of the counterweight 2.
  • the sensor 8 detects structure-borne sound waves, which transmits the guide rail to the sensor 8.
  • the structure-borne sound waves arise during operation of the elevator installation 10 due to vibrations of movable elevator components.
  • vibrations occur through the play between the guide elements of the car 1 or the guide elements of the counterweight 2 and the corresponding guide rails, by the drive unit, by the play in the bearings of the guide pulley 5.2, traction sheave 5.1, cabin roll 7.1, 7.2 and counterweight roller 4, and Vibrations of the carrying and blowing agent 3 itself.
  • vibrations can also be generated by movements of the cabin and landing doors, door drive and the like. Also on the bearing 4.1, on which the counterweight 2 is suspended, and on guide elements, where the counterweight 2 are guided on guide rails, vibrations occur.
  • the positioning of the sensor 8 in the area of the elevator installation 10 is not limited to that in the Example shown arrangement at the first end 3.2 of the supporting and / or blowing agent 3 and the detection of structure-borne sound waves limited.
  • the positioning of the sensor 8 as well as the manner of detecting the vibrations, namely sound waves or structure-borne sound waves depends on the component to be monitored and the design of the elevator installation 10, in particular the monitoring unit by a person skilled in the art.
  • a sensor 8 which is designed to detect structure-borne sound waves, can be positioned, for example, at the second end 3.1 of the carrier and / or propellant 3.

  • Structure-borne sound waves can also be detected in the region of the cabin 1, for example with sensors attached to a door panel of a car door, a housing of the door drive, a panel of a cabin wall or a cabin floor. In this way, vibrations of moving components, such as the car door, the carousel rollers 7.1, 7.2, the guide elements of the car 1 or door drive can be measured.
  • movable components of a shaft door generate vibrations that can be measured, for example, as structure-borne sound waves on the door panels of a shaft door.
  • a sensor is preferably arranged on a door panel.
  • Another group of sensors relates to sensors that detect sound waves.
  • Such sensors measure vibrations of components of the elevator system, which can be detected as air pressure waves.
  • the arrangement of these sensors is possible in the entire area of the shaft space, wherever the vibrations of the components can be detected as sound waves.
  • the Fig. 2 shows a monitoring unit 20, which comprises at least one sensor 8 and an evaluation circuit 9.
  • the sensor 8 transforms the detected sound or structure-borne sound waves into a signal and transmits this signal via a signal transmission path, typically a signal line or a wireless connection, to an evaluation circuit 9.
  • This evaluation circuit 9 is provided for the evaluation of the detected sound or structure-borne sound waves.
  • the evaluation circuit 9 has at least one analog / digital converter 14, a processor 11, a memory unit 12 and a time indication unit 13. Incoming analog signals from the sensor 8 are first converted by the analog / digital converter 14 into a digital signal. This digital signal is transmitted to the processor 11 and analyzed spectrally, in particular the frequencies and amplitudes of the transmitted sound or structure-borne sound waves.
  • the processor 11 determines frequency bands and determines a measured signal intensity for each of these frequency bands.
  • a frequency band is understood here to mean a frequency range, for example a frequency range from 1297 to 1557 Hz (see Fig. 3 ).
  • the signal intensity denotes a value which depends on the amplitude of the measured frequencies in this frequency band.
  • the processor 11 now sets the measured signal intensity for each particular frequency band and compares this signal intensity in the frequency bands with a first signal intensity stored in the memory unit 12 for the corresponding frequency band or a second signal intensity stored in the memory unit 12 for the corresponding frequency band the first signal intensity is.
  • the first signal intensity corresponds to the operating value and the second signal intensity corresponds to the threshold value.
  • the processor 11 counts the number of time steps in which the signal intensity during operation of the elevator installation reaches or exceeds the operating value and the number of time steps in which the signal intensity during operation of the elevator installation reaches or exceeds the threshold value.
  • the indication of time steps required for this purpose is provided by the time indication unit 13 to the processor 11.
  • the ratio of time steps with threshold value to time steps with operating value is determined in a further evaluation.
  • This ratio represents a quality value of the vibrations. If this quality value exceeds a certain critical quality value, then a state change alarm is triggered. Occasional disturbances, which occur only for a short period of time or few time steps, are thus filtered out.
  • the Fig. 3 shows an exemplary evaluation of the vibrations.
  • the measured frequencies are here divided into ten frequency bands between 0 and 2595 Hz. For each of these frequency bands, the signal intensity is recorded over time or time steps.
  • an operating value is specified for the frequency band 1297-1557 Hz. From this operating value, a threshold value is calculated, which here is for example 100% above the operating value. Preferably, the threshold value can be set to at least 10% above the operating value.
  • the signal intensity exceeds the allowable threshold for the latter frequency band.
  • the critical quality value is exceeded three times ("trip not ok"). In these three cases, a state change alarm is triggered. Once the signal intensity is above the threshold. Since in this case the calculated quality value falls below the predetermined critical quality value, no state change alarm occurs. The crossing of the threshold is due to a one-time short event, namely a hit on the side wall of the cabin ("hit car wall"). This short event is filtered out by the additional evaluation of the quality value.
  • the critical quality value is set here, for example, to 10%. This means that for every 100 time steps with a measured signal intensity that is above the operating value, there will be 10 time steps with a measured signal intensity that is above the threshold value. Accordingly, in the evaluation described above, the quality value is three times the critical quality value of 10%, and once the quality value is below the critical quality value of 10%, despite exceeding the threshold value.
  • the critical quality value is preferably determinable to at least 10%. In further preferred Executions, the critical quality value can also be set to at least 20, 30, 40 or 50%.
  • the critical quality value is preferably stored in the memory unit 12 of the evaluation circuit 9.
  • the operating value is preferably determined by means of a learning run. During this learning run, the sensor 8 measures the vibrations that occur. In the evaluation circuit 9 or the processor 11, a characteristic signal intensity for each frequency band is determined therefrom, for example a maximum signal intensity or an average signal intensity. This signal intensity is then stored in the memory unit 12 of the evaluation circuit 9 as an operating value.
  • the threshold value is preferably calculable from the operating value and represents a characteristic signal intensity increased by a certain percentage. This threshold value can be calculated in the processor 11.
  • a further evaluation of the vibrations relates to a self-test of the sensor 8 or the signal transmission path.
  • the evaluation circuit 9 or the processor 11 counts the time steps in which the signal intensity does not reach the operating value. These time steps represent a period of time in which the elevator installation 10 stands still.
  • the processor 11 checks whether this period of time exceeds a certain time value. For this purpose, the processor 11 compares the time duration with a time value stored in the control unit. If the processor 11 detects an exceeding of this time value, then a sensor malfunction is assumed. This time value is calculated on the basis of a characteristic profile of use of the elevator installation 10 and represents a period of time in which the elevator installation 10 would have had to be used with a very high probability. If this time value is exceeded, a state change alarm is also triggered.
  • the triggering of the state change alarm leads at least to the fact that the elevator installation 10 is provided for a maintenance work in which the malfunction of the elevator installation 10 is remedied. For example, a service center is alerted to instruct a service technician to service the corresponding elevator installation 10. Alternatively, when a state change alarm is triggered, the service technician is notified directly via a mobile radio receiving system in communication with the elevator installation to service the corresponding elevator installation 10.
  • the elevator system is also silent when a state change alarm occurs.
  • a service technician is also instructed to wait for the lift system 10 and to put it back into service.
  • the detection of the vibrations by the sensor 8 and the evaluation thereof in the evaluation circuit 9 according to the above procedure is not limited to the configuration of the elevator installation 10 shown.
  • the monitoring of the vibrations of moving components also relates to elevator systems with a suspension ratio of 1: 1, 3: 1, etc., counterweightless elevator systems, elevator systems with machine room or, more generally, elevators in which moving components cause vibrations.
