Description

  The present invention relates to an elevator vibration meter.

  As an elevator continues to be used, vibration and noise may increase, which may impair the comfort of the user and lead to a decrease in service. For this reason, it is necessary to carry out regular maintenance work and maintain a good condition at all times, but in order to perform proper maintenance work, it is important to accurately measure and evaluate the state of the elevator. It is.

  Conventionally, as a means for measuring and evaluating vibration and riding comfort during elevator car travel, there is a technique described in Japanese Patent Application Laid-Open No. 2000-344436. This technology includes acceleration detection means for detecting the acceleration of the elevator car, and quality determination means for determining whether or not the riding comfort of the elevator is good based on the output of the acceleration detection means. The elevator control panel automatically evaluates vibration and ride comfort during elevator operation, and stores the data so that engineers can control the elevator with a remote monitoring device installed in a remote location without going to the site. It can be connected to the panel and check the data.

  Further, the technology described in Japanese Patent Application Laid-Open No. 2006-264858 is provided with a connector connection portion in an elevator car, and vibration and noise data of an elevator car and a hoisting machine are connected to a connector connection portion of a lift car that performs maintenance work. Connected to the detector, and the vibration and noise data of the car and hoist detected by these detectors are taken to diagnose the presence or absence of abnormalities, and the elevator control program and control constants are determined according to the diagnosis results. It is provided with a maintenance terminal device that changes and adjusts.

  However, in the above-mentioned Japanese Patent Application Laid-Open No. 2000-344436, it is necessary to provide an acceleration detecting means, a memory for storing measurement results, and a communication means for connecting to a remote monitoring device on the elevator car. When the test operation for automatically evaluating vibration and ride comfort needs to be set in advance, and the test conditions cannot be satisfied at the test operation execution date and testing is not possible Had the problem that the workers had to go to the site and perform measurements.

  In addition, as described in Japanese Patent Application Laid-Open No. 2006-264858, a connector connection portion is provided in a cage, and the method of attaching the detector every time maintenance work can reduce the initial cost of the detector. Since the data processing is performed by the control panel of the elevator, it is necessary to incorporate the human power and signal processing circuit of the detector in advance, so it is not always possible to reduce the initial cost. there were.

  In addition, for the measurement and evaluation of vibration and ride comfort during elevator car travel, it is conceivable to carry out measurement by bringing a measuring device independent of the elevator, but the relationship between the measurement result and the operating state of the elevator is considered. Because it is difficult to reflect accurately and generally the measuring device becomes large, it takes a lot of time for preparation work and removal work before the measurement is carried out, and the elevator unusable time becomes long. There is also a problem that the service to general users is reduced.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to enable vibration, ride comfort measurement, and evaluation during traveling of an elevator car to be carried out inexpensively, easily, and in a short time.

In order to achieve the above object, the present invention relates to an elevator vibration meter that is connected to an elevator control panel by communication and includes a three-dimensional acceleration sensor, and receives an elevator control signal from the control panel to Means for detecting a change, and means for recording the measured value of the three-dimensional acceleration sensor in response to the change in the driving state, and transmitting and storing the measured value in a data server by the second communication means. And

  Because of this, this elevator vibration meter is easy to carry and easy to use, so measurement preparation and removal work can be carried out in a short time. Is measured, transmitted to the data server and recorded, so that the initial cost is low and the service to general users is not reduced.

  As described above, according to the present invention, the measurement results are transmitted to and stored in the data server, so that it is possible to easily compare the data change tendency with the passage of time and the measured values with other sites.

It is a block diagram which shows one Example of the vibration of an elevator, riding comfort measurement, and the evaluation method by this invention. It is a work flow figure showing one example of vibration of an elevator, riding comfort measurement, and an evaluation method by the present invention.

  Hereinafter, an embodiment of an elevator vibration, ride comfort measurement and evaluation method according to the present invention will be described with reference to FIGS.

  FIG. 1 is a block diagram showing the overall configuration, and FIG. 2 is a work flow diagram of the system.

  In FIG. 1, an elevator car 10 is moved up and down in a hoistway by a control panel 1 and an electric motor (not shown), and serves as a vertical moving means in a building. A car control panel 11 is mounted on the car 10, communicates with the control panel 1, and controls input / output processing with the operation panel 12 in the car. Further, the car control panel 11 has communication means 13 for communicating with a maintenance terminal (not shown) used for maintenance work, and the car control panel 11 and the maintenance terminal can communicate with each other, if necessary. The maintenance terminal can obtain various operation states of the elevator such as the operation direction, speed, and car position of the elevator from the car control panel 11. The communication between the car control panel 11 and the maintenance terminal is a communication system different from the communication between the car control panel 11 and the elevator control panel 1.

  In addition, an elevator vibrometer 20 is connected to a communication terminal of a maintenance terminal used for maintenance work, and the elevator vibrometer 20 incorporates a three-dimensional acceleration sensor (not shown) that measures vibrations in the vertical and horizontal directions. ing. The elevator vibration / riding comfort measurement program (not shown) installed in the elevator vibration meter 20 records acceleration in a time series using the measurement values of the three-dimensional acceleration sensor described above, and controls the car. A change in the operating state of the elevator is detected from the elevator control signal obtained by the communication function between the panel 11 and the elevator vibrometer 20 and is associated with the data obtained from the three-dimensional acceleration sensor according to the detected change in the operating state. Record. In addition, this elevator vibration and ride comfort measurement program evaluates elevator vibration and ride comfort based on the recorded magnitude of acceleration and changes in acceleration per unit time, and a series of measurement result data is filed for the elevator. It can be stored in a memory (not shown) built in the vibrometer 20. Further, the maintenance terminal is connected to the data server 30 via a general public line or the Internet, and can transfer data stored in the maintenance terminal.

  Next, the vibration of the elevator, the ride comfort measurement, and the evaluation method of this embodiment will be described with reference to the work flow diagram of FIG. The flow shows the operation of the elevator vibrometer 20 and the operation control of the elevator in parallel, and the steps are TS1, TS2,..., ES1, ES2,. First, the operator stops the elevator at ES1, puts a safety fence that is not available to ordinary passengers, then runs at low speed at ES2, moves the car to the hall height, and opens the hold door when the hold door is opened. You can see the car from the top and board the car or reach the equipment as needed.

  When the hold door is opened at ES3, the vibration, ride comfort measurement, and evaluation program that are pre-installed in the elevator vibrometer 20 are activated at TS1. And after inputting conditions required for measurement, such as the specification of the said elevator measured with TS2, it is set as a measurement standby state with TS3. In this state, the worker installs the elevator vibrometer 20 at a predetermined position on the car. The vibration meter 20 for elevators in the measurement standby state in TS3 is configured to perform communication periodically. When installed at a predetermined position on the car, communication with the car control panel 11 is established, and the elevator control panel. 1 recognizes that the vibration and ride comfort measurement program is in a measurement standby state through the car control panel 11, while the elevator vibrometer 20 confirms that the elevator control panel 1 has recognized the elevator vibrometer 20, Complete measurement preparation.

  The operator closes the hold door, moves the elevator at a low speed, and performs an encryption operation on the operation panel 12 in the car, thereby setting the electric measurement mode. Here, the electro measurement mode refers to an operation mode in which the elevator control panel 1 performs a constant high speed or low speed operation without responding to the hall call so that the user cannot use the elevator. When this elevator measurement mode is set, the elevator control panel 1 notifies the elevator vibration meter 20 that the operation mode has been switched via the car control panel 11. When the elevator vibrometer 20 recognizes that the elevator is in the measurement mode and sends a response to that effect to the elevator control panel 1, the elevator starts measurement operation and appropriately transmits the elevator control information to the elevator vibrometer 20. To do. On the other hand, the elevator vibrometer 20 simultaneously records the acceleration sensor data built into the elevator vibrometer 20 with the start of the measurement operation, and the elevator control information and the acceleration sensor data obtained through communication with the car control panel 1. .

  When the measurement operation ends at ES7, the elevator transmits the operation end to the elevator vibrometer 20, and the elevator vibrometer 20 ends the measurement at TS6. Upon completion of the measurement, the measurement result is stored as a measurement result file in the memory of the elevator vibrometer 20, and the communication between the car control panel 1 and the elevator vibrometer 20 is terminated. As before the measurement, the operator operates the elevator at a low speed and moves the car from the hall to a position where the elevator vibrometer 20 on the car can be collected when the hold door is opened at ES9. Then, the hold door is opened at ES9, and the vibration meter 20 for the elevator is collected (TS7).

  The collected vibration meter for elevator 20 displays the vibration during the traveling of the elevator by the measurement and the riding comfort evaluation result, and the operator can inspect and adjust the elevator as necessary.

  The measurement result file stored in the elevator vibration meter 20 can be connected to the data server 30 via a general public line or the Internet, and the data stored in the elevator vibration meter 20 can be transferred.

  In this way, when an operator goes to the site for maintenance work, the vibration and ride comfort measurement program is started on the car and the prepared elevator vibration meter is installed, and then the elevator is measured and operated with the operation panel in the car. The elevator car control panel and the elevator vibration meter communicate with each other autonomously to perform vibration, ride measurement, evaluation, and judgment, so the measurement work can be done easily and in a short time. By transmitting and accumulating the results to the data server, it is possible to provide a measurement method that makes it easy to compare the trend of data changes over time and the measured values at other sites.
