Definitions

  • the present invention relates generally to the elevator art field.
  • the invention relates to a technique for monitoring use of an elevator.
  • Elevator equipment in particular those intended for the transport of persons, must be checked regularly to ensure the necessary safety.
  • the legislator sets a deadline for operational areas within which elevator facilities are to be checked.
  • an elevator may be subject to varying degrees of progressive wear.
  • the present invention is intended to create a possibility for individually optimizing maintenance intervals for elevator devices. This should increase the safety in the use of elevator equipment.
  • An elevator device comprises at least passenger and goods lifts, passenger lifts, stairlifts (or other types of lifts for people with physical disabilities), construction site lifts, access ramps, platform lifts and escalators and moving walks.
  • FIG. 3 is a flowchart showing a method 100 for monitoring use of an elevator apparatus 1000 based on data indicative of use of the elevator apparatus 1000.
  • a system 200 according to the invention for implementing the method 100 is described in FIG Fig. 4 shown.
  • a use of the elevator device 1000 means a use in which the elevator device 1000 is actually in motion, such as a travel of the elevator device 1000 between two rest positions. Standstills and shutdowns of the elevator device 1000 are not considered to be use.
  • first of all data is recorded which indicates a use (movement) of the elevator device 1000.
  • the detection takes place with attached to the elevator device sensors 230-232 (see Fig. 4 ). These may measure the duration of use, the distance traveled during use, the load weight during use and / or the consumption of electrical power during use.
  • a usage parameter P for the elevator device 1000 is calculated in a subsequent second step 120.
  • the usage parameter P is an indicator of the strength of use of the elevator device 1000.
  • the strength of the use of the elevator device 1000 means at least the frequency of use (ie how often or how long the elevator device has been moved). In addition to the frequency of elevator use, the load on the elevator device 1000 during use can still be taken into account.
  • the frequency of use can be described by the number N of uses, the duration of use t and / or by the distance traveled s of the elevator device 1000.
  • the load on the elevator device 1000 during use may be described by the load weight g , for example. Additionally or alternatively, the consumed electrical energy E can be used to describe the strength of the use of the elevator device 1000.
  • the calculated usage parameter P merely indicates the frequency of use, ie how often the elevator device 1000 is moved.
  • the usage parameter P can be calculated by incrementally summing the acquired usage durations t or traveled distances s of successive uses. As time progresses, therefore, the value of the usage parameter P increases. Alternatively, only the number of uses N can be counted as time progresses.
  • the usage parameter P indicates the total usage time T, the total distance traveled S, or simply the total number N of uses with respect to a given starting point. Accordingly, the calculated usage parameter P has the dimension of a time or a path or is dimensionless in the case of counting the uses.
  • t i and s i can take different values for each use i , depending on how long the period of use has been or which distance the elevator device 1000 has effectively traveled in use i . It will also be understood that the usage number n i only counts the i th use event and thus is 1 for each use by definition .
  • the predetermined starting point for the calculation may be the time of the first operation after a new installation of the elevator device 1000 or just a restart of the elevator device 1000 after a regular maintenance.
  • the calculation of the usage parameter P restarts in this case.
  • the calculated usage parameter P indicates the frequency of use as well as the load during each use.
  • the use of parameter P can be calculated by the i detected for each user usage time t i, the distance traveled s i or the detected Usage number n i (this is for each use by definition 1 as set forth above) weighted with a dimensionless weighting factor F calculated from the detected load weight g .
  • the weighting factor F i for the i-th use is calculated from the quotient of the detected loading weight g i for the i-th use and the maximum weight approved by the manufacturer.
  • the usage parameter P is recalculated.
  • the (weighted) use values ie s i , t i , n i , F i * s i , F i * n i or F i * t i ) determined from the acquired sensor data are added to the previous usage values, as stated above , The value of the usage parameter P thus grows incrementally with each new use.
  • the value of the usage parameter P calculated in step S120 is compared with a predetermined usage threshold SP .
  • the usage threshold SP indicates the need for maintenance of the elevator device 1000.
  • the usage threshold SP is thus a measure of a maximum tolerable use up to a maintenance. It is pre-set by a manufacturer, operator or maintenance worker of the elevator device 1000 so that, when operated properly, no wear-threatening wear on the elevator device 1000 is expected when the usage parameter value P reaches the usage threshold SP .
  • the Usage threshold SP can be reset after each maintenance.
  • the usage threshold SP can be adapted to the age of the elevator device 1000. It can be reduced in older elevator device 1000.
  • the usage threshold SP has the same physical dimension as the calculated usage parameter P. Depending on the usage parameter P used , the usage threshold SP either gives an upper bound on the total weighted distance traveled S, the total usage time T or an upper bound on the (weighted) total number N of uses.
  • an output signal is generated which is provided for the acoustic and / or visual representation of the comparison result.
  • the generated output signal is provided to an output device (eg smartphone, PC) for audible and / or graphical representation.
  • the generation and provision of the output signal can again take place after each use (so to speak in real time), so that an operator, owner and / or user is always informed about the progressive use.
  • the comparing step 130 may further include, after each use, a query 132 as to whether the usage parameter meets or exceeds a predetermined warning limit of 80% of the usage threshold SP . If the usage parameter P falls below the 80% warning limit (no branch), thus, the method 100 returns to step 110 to acquire data of subsequent use of the elevator device 1000.
  • the usage parameter P after use of the elevator device 1000 reaches or exceeds the predetermined warning limit of 80% (yes branch in FIG Fig. 2 ), a warning signal additional to the output signal is generated and output (step 142).
  • the warning signal can in turn be an optical and / or acoustic warning signal for output on an output device (eg smartphone, PC). Warning signal and output signal can be output simultaneously.
  • a further query 134 is also provided. In this query, it is checked whether the usage parameter P is greater than or equal to the usage threshold SP . If this is not the case (no decision), the method returns to step 110.
  • the usage parameter P reaches or exceeds the usage threshold value SP (yes decision)
  • the shutdown or shutdown of the elevator device 1000 is initiated. The switching off 180 of the elevator device 1000 can be supplemented or replaced by the output of a further warning signal.
  • Switching off the elevator device 1000 may include automatically maneuvering the elevator device 1000 to a predetermined position.
  • the elevator device 1000 is a passenger elevator in a multi-storey building. If the usage parameter P exceeds the usage threshold SP in this case, the elevator for example can drive to the ground floor and open the doors. When all passengers have exited, the passenger elevator can automatically close the doors and switch off until maintenance has taken place.
  • the implementation of the shutdown function 180 opens up additional possibilities in terms of increasing safety standards in the use of elevator equipment.
  • step 120 of calculating the usage parameter P may be in addition to that described above in connection with FIG Fig. 1 described calculation of an absolute value of the use parameter P additionally one Calculate a usage rate R (step 122) that describes the amount of usage within a given time interval.
  • a future date may be selected from the currently determined using parameters P and the above calculated Benutungsrate R then in a subsequent step 124 by comparison with the use of threshold value SP can be estimated at which the usage parameters P is the use of threshold value SP expected to reach or exceed.
