Definitions

  • the invention relates to a method and a mobile device for carrying out a catching test of an elevator installation.
  • the safety-relevant components When taking off an elevator installation, the safety-relevant components must be checked. For this purpose, a so-called catch test is performed to test the functionality of the safety brake.
  • the elevator car is loaded with a prescribed mass and accelerated to rated speed during a test drive. Subsequently, the safety brake is triggered and the elevator car brought to a standstill within a predetermined path.
  • the object of the present invention is therefore to be able to evaluate determined acceleration data in a simple manner and to be able to transmit a test result to the fitter on the system.
  • the object is achieved by a method for carrying out a catching test of a Elevator installation, in which acceleration data of an elevator car are detected during a test drive by means of a mobile device arranged on or in the elevator car, the acquired acceleration data are transmitted from the mobile device to a central server, a braking distance of the elevator car is determined from the transmitted acceleration data and to a Receiver is transmitted whether the determined braking value complies with a required length.
  • the same procedure can also be used for counterweights if equipped with a safety gear.
  • the invention is based on the finding that it is difficult for a fitter in the field when carrying out a catching test to measure a skid mark left on the guide rails by the catch brake.
  • the skid mark may become unclear at the beginning and at the end, so determining its exact length may require a lot of experience and still be flawed.
  • an installer after carrying out a test drive, an installer must first remove the mass in the cabin that is required for the catch test before being able to approach the corresponding location on the roof of the car at which the braking distance is to be measured. But only after measuring the braking distance, the fitter knows if he has to perform the catch test again. If the catch test has failed, then the fitter must then re-load the entire mass to carry out another test drive into the cabin.
  • the use of a mobile device which has an acceleration sensor and a mobile data communication is proposed.
  • the mobile device can be easily attached to or in an elevator car by the fitter.
  • the device records the acceleration data of the elevator car and this data is then transmitted to a central server for evaluation.
  • the transmission can take place immediately if there is a data connection, but it can also be done subsequently if
  • the fitter has removed the mobile device from the elevator car and is located with the device in a place where a data transfer is possible.
  • a braking distance of the elevator car is determined from the acceleration data, and the fitter can then be informed promptly of the result of the catching test.
  • the test result is transferred back to the mobile device or the test result is transmitted to another receiver, the fitter or another person with it.
  • test results can be stored and managed centrally on the server. Due to the automatic evaluation, an interpretation by the fitter is no longer necessary, which leads to a better data quality in the test results.
  • data from the elevator installations can be compared with one another on the server, so that it is possible to diagnose the results of various elevator systems or different geographically or temporally specified test procedures.
  • the fitter gets the result of the catch test promptly notified and thus he can perform the test quickly if not passed again.
  • a further advantageous embodiment is that from the acceleration data speed and distance of the elevator car are derived from the speed of a first point is determined at which a braking action was initiated during the test drive, from the speed of a second point is determined at the elevator car has come to a standstill and the braking value and / or the delay is determined from a distance traveled by the elevator car between the first point and the second point distance.
  • the speed of the car and the distance covered by it are derived on the server.
  • the calculation options do not have to be carried out directly on the mobile device, but can be calculated using a program stored centrally on the server. However, the calculation of the speed and the distance traveled can also take place elsewhere, for example on a server separate computing unit or in the cloud, if so desired.
  • the server sends the acceleration data stored on it to the desired evaluation unit. The evaluated data however, they are sent back and stored and managed centrally on the server. In this procedure, only the data collection of the acceleration data is carried out by means of the mobile device and the mobile device can receive the test results again after evaluation.
  • a further advantageous embodiment is that the plant to be tested elevator system descriptive system data can be entered on the mobile device and transmitted to the server.
  • a commissioning number of the installation or a name of the inspector carrying out the catching test can be entered by the fitter on site.
  • the entry of an address of the elevator system is possible.
  • the installer can select which elevator system is involved and test parameters can be entered, such as the height of the elevator installation, the permitted speed or the cabin weight.
  • the data entered is transmitted to the central server for evaluation before the test drive or after the test drive has been carried out together with the determined acceleration data.
  • a position information that was determined by the mobile device via GPS can also be transmitted.
  • the data can then be processed in the evaluation unit, and on the basis of the entered descriptive system data, a maximum braking distance defined for this system can be selected, which then serves as a reference for the braking distance determined from the acceleration data.
  • different braking distances can be defined for different elevator systems, but these are stored centrally, which releases the installer from the selection of the braking distance relevant to his system to be tested.
  • the test data are stored together with the system data on the server and are used to document the catches taken.
  • a further advantageous embodiment is that by means of the mobile device in the elevator system stored descriptive system data, for example, read using a QR code and transmitted to the server.
  • the fitter does not have to enter the descriptive system data himself, but rather they are already deposited, for example, in the control of the elevator installation and can be read out by means of an interface from the mobile device.
  • This further facilitates the implementation because the installer saves time, which otherwise would have been needed to enter the data, and also avoids errors when entering the data.
  • the elevator system itself already brings along its master data, which only needs to be read out and then transmitted to the central server.
  • a further advantageous embodiment is that the server can transmit instructions for carrying out a further test drive to the mobile device if the determined braking value does not correspond to the required length.
  • the fitter must repeat the test again.
  • the fitter can be informed of such instructions which are assigned to the respective test after analysis of the acceleration data. You can also transfer pictures, videos and more complex instructions for further testing. This can help the installer to successfully complete another test to be performed.
  • the modifications are also stored centrally on the server, so that an evaluation of different catch tests and necessary measures to pass a catch test can be done.
  • test results of all elevator systems tested are stored centrally on the server. This will create a knowledge base that will have all the lifts in the field and their test results. This allows for enterprise-wide analysis and diagnosis of test results.

  • An application is installed on the mobile device which allows the installer to bring the device into an active state where it can collect the acceleration data during the test drive.
  • the mobile device can then be attached to the elevator car. This can be done by means of a special shell into which the mobile device is inserted and which is connected to the elevator car via vibration-damping elements. After the mobile device is fixed in the shell and before the lift fitter starts the test drive of the elevator car, he can start the test by means of the application stored on the mobile device and thus activate the actual data collection. The data recording is thus very easy to handle for the fitter on site.
