DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an elevator operation data collection device according to an embodiment of the present invention. The terminal device 1 is provided with a control power supply 11, an up operation relay contact 12, a down operation relay contact 13, a frequency counter 14, an integrating time counter 15, and a communication control device 16. A parallel circuit of an operation relay contact 12 and a down operation relay contact 13 and a parallel circuit of a frequency meter 14 and an integrating time meter 15 are connected in series. The output terminal of the frequency meter 14 and the output terminal of the integrating time meter 15 are connected to the communication control device 16.

Here, the up-operation relay contact 12 is closed by energization of an up-operation relay (not shown) for operating the elevator car up, and opened when the car stops.
The down operation relay contact 13 is closed by the action of a down operation relay (not shown) for operating the elevator car down,
This is a contact that opens when the car stops. In addition, frequency meter 1
Reference numeral 4 has a function of counting the number of times the up-operation relay contact 12 and the down-operation relay contact 13 are closed and storing the count value. Further, the integrating time counter 15 has a function of storing an integrated value of the time during which the up-operation relay contact 12 and the down-operation relay contact 13 are closed. The communication control device 16 has a function of reading out and outputting operation data stored in the frequency meter 14 and the integrating time meter 15.

The monitoring center 2 is provided with a communication control unit 21, an operation unit 22, a storage unit 23, a comparison unit 24, and a display unit 25. The output terminal of the communication control unit 21 is connected to the operation unit 22, The unit 22 is connected to the storage unit 23, the comparison unit 24, and the display unit 25, respectively. Here, the communication control device 21 has a function of taking in elevator operation data from the terminal device 1 via the communication control device 16 and the communication line 3. The operation unit 22 performs a required operation using the operation data input from the communication control device 21 and the data stored in the storage unit 23, and outputs the obtained data to the comparison unit 24. And a function of outputting the calculated result to the display unit 25.

Next, the operation of this embodiment will be described. When the elevator car is started for up operation, an up operation relay (not shown) is energized to close the up operation relay contact 12, and when the car stops, the up operation relay contact 12 is activated.
Is open. Similarly, when the elevator car is started for down operation, a down operation relay (not shown) is energized to close the down operation relay contact 13, and when the car stops, the down operation relay contact 13 is opened. State. Thus, when the elevator is operated, the frequency meter 1
4 is an up operation relay contact 12 and a down operation relay contact 1
The number of closings of 3, ie, the number of times of starting the car, is counted and recorded. In addition, the integrating time meter 15 is used for the up-operation relay contact 12.
And the closing time of the down-operation relay contact 13, ie, the operating time of the car, is integrated and recorded.

On the other hand, in the monitoring center 2, the monitoring staff periodically and at predetermined intervals of time, or the maintenance staff who is scheduled for maintenance and inspection work periodically and periodically counts the frequency meter 14 of the terminal device 1. The operation data stored in the total 15 is fetched. When a command for taking in is input, the arithmetic unit 22
Activates the communication control device 21 and, via the communication line 3,
The communication control device 21 is connected to the communication control device 16 of the terminal device 1, so that the operation data stored in the frequency counter 14 and the integration time meter 15 are transmitted to the communication control device 16 and the communication line 3.
And input to the arithmetic unit 22 via the communication control device 21. Also, by this operation, the frequency counter 14 and the integration time counter 15
Is cleared.

When the frequency meter 14 and the integrating time meter 15 are attached after the elevator is installed, it is necessary to correct the operation data input to the arithmetic unit 22 by the above operation. In this case, the operation unit 22 corrects the operation data from the operation days after the elevator installation and the measurement days as described below,
Output to the storage unit 23. When the correction is not necessary, the calculation unit 22 adds the total value of the measurement values up to the previous time and the current measurement value, and outputs the result to the storage unit 23. The storage unit 2
3 stores information on an elevator operation start date and a measurement start date of the number of times of operation of the relay, which are data necessary for correction for the elevator to be monitored. Further, even in the case of operating data that needs correction, if correction is performed once so that correction is not performed many times, the fact that correction has been performed is written to the storage unit 23, and the corrected state is stored thereafter. No correction is made for the operating data that is in use. This prevents the same data from being corrected many times. Arithmetic unit 22
Outputs the corrected value or the calculated total value to the comparison unit 24. The comparison unit 24 compares the input value with a preset set value. If the former exceeds the set value, the display unit displays the value. The unit 25 displays a message to replace the device.

Next, a method of correcting the operation data will be described with reference to FIGS. FIG. 2 is a flowchart illustrating a correction method performed by the calculation unit 22, and FIG. 3 is a diagram illustrating an example of a measured value of operation data and a total value after correction.
When the number of relay operations to be corrected is input, the arithmetic unit 2
2 calculates the elevator operation days A from the elevator operation start date and the measurement date stored in the storage unit 23 (step S1). Next, the number of measurement days B is calculated from the measurement start date and the measurement date of the number of relay operations stored in the storage unit 23 (step S2). Next, based on the number of days A calculated in step S1 and the number of days B calculated in step S2, a ratio C of the two is obtained.
(A / B) is calculated (step S3).

Next, the measured number of relay operations is multiplied by C calculated in step S3 (step S4). The value thus obtained is the corrected number of times of operation of the relay.

Next, an example of the correction of the operation data and the total value after the correction will be described with reference to FIG. In this case, the operation start date of the elevator is January 1, and the measurement start date of the number of times of operation of the relay is August 1. The correction is performed when data on the first measurement date of September 1 is input. The number of operating days A of the elevator is 240 days from January 1 to the end of August (assuming that one month is 30 days; the same applies hereinafter), and the number of days B of measuring the number of relay operations is from August 1 to the end of August. 30 days, ratio A /
B (C) is 240/30 = 8. In the example shown in FIG. 3, since the measurement value on September 1 is 100, the total value of the number of relay operations after the correction is 100 × 8 = 800 times. Thereafter, by adding the measured value of the number of times of operation of the relay to the corrected number of times of operation of the relay, an accurate number of times of operation of the relay since the start of operation of the elevator is calculated.

As described above, in this embodiment, the number of times of operation of the relay during the non-measurement period from the start of operation of the elevator to the start of measurement with the measuring instrument attached is determined by the number of operating days of the elevator and the operation of the relay. Since the correction is performed based on the number of measurement days, it is possible to accurately determine the relay replacement time.

In the description of the above embodiment, the number of times of operation of the relay by the frequency meter has been described as an example. The present invention can be applied to all numerical values serving as criteria for maintenance and inspection work, such as lighting, lighting time, and the number of operations of each safety device. Further, in the description of the above embodiment, an example in which the correction is performed by the calculation unit 22 of the monitoring center 2 has been described. Can be performed by the terminal device 1 as well. further,
In the description of the above embodiment, the timing for performing the correction was performed at the first measurement. However, when it is clear that the timing for performing the correction does not reach the set value, the timing for performing the correction may be any time. Further, in the description of the above embodiment, as the data for correcting the operation data, the number of operating days from the operation start date of the elevator was used, but if the elevator has a running hour meter attached to the elevator from the beginning of the operation of the elevator, The operation data may be corrected based on the travel time.
