[0002]

2. Description of the Related Art Since an uncomfortable ride of an elevator may cause discomfort and anxiety to a user, it is essential to operate the elevator comfortably when the user is transported by the elevator. Is the condition. The ride comfort of the elevator largely depends on the speed control technology of the car, the installation accuracy of the elevator, and the setting state of the car guide device. For this reason, conventionally, in order to confirm the ride comfort of the elevator, it has been performed to measure the traveling characteristics of the elevator by using the acceleration detector and the recording device at the time of completion of installation and maintenance of the elevator. It was

In this conventional measurement, an acceleration detector and a recording device for recording the detection signal of the acceleration detector on a recording sheet are brought into the car and installed to drive the car. Measure the acceleration of the car while running,
Record the measured value on the recording paper of the recording device. Then, the obtained recording result is compared and examined with reference data measured in advance to determine the ride comfort of the elevator.

[0004]

In the above-mentioned conventional measurement, it is necessary to transport a large and heavy recording device and install it in a car, which imposes a heavy burden on a measuring operator and causes the recording paper of the recording device to be damaged. Since the vibration value is visually read from the recorded data waveform for determination, there is a problem that the measurement error is relatively large. In addition, continuous vibration during steady running of the elevator often has a short vibration cycle.In that case, in order to clearly obtain the vibration waveform and accurately read the frequency,
Corresponding to the state, complicated adjustment such as setting the paper feeding speed of the recording device to a high speed is required.

The present invention has been made in view of the current state of the traveling characteristic inspection of the elevator as described above, and its purpose is to inspect the traveling characteristic of the elevator easily and accurately. To provide a device.

The object is to provide an acceleration detector for detecting the acceleration of an elevator car, and a first storage device for storing detection data of the acceleration detector.
A control device for calculating the amplitude value in the region from the zero point of the detection data to the next zero point and each time value from the recording start time to the detection time of each amplitude value, and the calculation obtained by this control device This is achieved by taking means having a second storage device for storing processed data and a display device for displaying the arithmetic processing data.

[0007]

By taking such means, the detection data of the elevator car detected by the acceleration detector is stored in the first storage device, and the control device operates to read it from the first storage device. Based on the detected data, the calculation processing of the amplitude value in the region from the zero point of the detected data to the next zero point and each time value from the recording start time to the detection time of each amplitude value is performed. The arithmetic processing data thus obtained is stored in the second storage device, and is read from the second storage device and displayed by the display device.
