Abstract

<P>PROBLEM TO BE SOLVED: To provide an elevator monitoring center system capable of automatically performing the individual setting of proper determination values by discriminating that the individual setting of the determination values is required by measured values collected regularly from an elevator monitoring terminal monitoring a special elevator. <P>SOLUTION: Based on the measured values collected regularly from the elevator monitoring terminal 3, if the specified measured values come out of the range of the determination values successively by the number of specified times, the measured values are not varied, and the trouble detection history of the elevator is absent, by the difference of a standard averaged value 17b obtained from the measured values of the elevator monitoring terminal of the elevator having the same specification as the individual averaged value 17a obtained from the measured values of the elevator monitoring terminal 3, the individual determination value 19a formed by adding the difference to a standard determination value 12a is calculated to set the determination value automatically. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to an elevator monitoring center apparatus that sets determination values for setting and determining monitoring items of an elevator monitoring terminal and collects various information measured and recorded by the elevator monitoring terminal.

Conventionally, an elevator remote fault diagnosis system that measures the elevator running performance and issues a predictive failure signal when the measured value of the measurement item deviates from the preset judgment value range, makes a judgment according to the running condition of the elevator There has been proposed an elevator remote fault diagnosis system that can set a value range and set a judgment value range at the time of diagnostic operation to be narrower than that at the time of normal operation, and can perform a more detailed diagnosis of the driving state (for example, (See Patent Document 1).
JP 11-349249 A (paragraph numbers 0050 to 0064, FIG. 1)

  However, in the above-described conventional method, in a special specification elevator that has been adjusted so that it cannot be identified by the elevator monitoring terminal, the state in which the measured value of traveling performance greatly deviates may be a normal value. Since the abnormality is always detected, the judgment value itself must be set individually.

  An object of the present invention is to determine that an individual setting of a judgment value is necessary based on measurement values periodically collected from an elevator monitoring terminal, and automatically set an appropriate individual judgment value for the elevator monitoring terminal. It is in providing the elevator monitoring center apparatus which can be performed.

  In order to achieve the above object, the present invention detects a case where a specific measurement value is out of the range of the determination value continuously for a predetermined number of times based on periodically collected measurement values, and When there is no variation in the measured value and there is no history of failure detection of the elevator, the average value of the measured value and the standard judgment value are calculated from the distribution of the measured values of the elevator monitoring terminals of elevators with similar specifications other than the elevator. By calculating the relationship between the standard average value and the average value of the measurement value of the elevator monitoring terminal, the individual determination value of the measurement value is calculated automatically by applying the difference to the standard determination value. Is configured to do.

  By configuring in this way, it is possible to automatically set an appropriate individual determination value for an elevator monitoring terminal that requires the measurement value of the elevator monitoring terminal to be individually set as a determination value.

  Embodiments of the elevator monitoring center apparatus of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram of an elevator monitoring center apparatus according to an embodiment of the present invention.

  The elevator monitoring center device 1 of the present embodiment shown in FIG. 1 is configured to exchange information by communication with the elevator monitoring terminal 3 via the general line 2, and when the determination value is set by the elevator monitoring center device 1. The determination value creation unit 11 extracts the standard determination value 12a to be set in the elevator monitoring terminal 3 from the standard determination values stored in the standard determination value storage unit 12, and uses the communication unit 13 to connect the general line 2 Is connected to the communication unit 31 of the elevator monitoring terminal 3, and the determination value is stored in the determination value storage unit 32. Accordingly, the elevator monitoring terminal 3 uses the determination value stored in the determination value storage unit 32. Then, the measurement value measured by the measurement unit 34 is compared and determined by the comparison determination unit 33.

  The elevator monitoring terminal 3 periodically records and updates the measurement value storage unit 35 using the measurement value measured by the measurement unit 34, and the failure detection unit 36 detects the failure of the elevator using the failure state as data. The record is stored in the history storage unit 37.

  On the other hand, the elevator monitoring center device 1 periodically reads out the measurement values in the measurement value storage unit 35 and the failure history in the failure history storage unit 37 via the general line 2 and reads out the measurement values read out from the measurement value storage unit 35. The value is stored in the measurement value storage unit 15 together with the date read via the measurement value determination unit 14, and stored in the failure history storage unit 16 together with the date of reading out the failure history from the failure history storage unit 37.

  Among the measurement values periodically collected by the measurement value determination unit 14, it is detected that a specific measurement value is out of the determination value range, and the measurement value is counted outside the determination value range. When the value outside the determination value range of the measurement value is stored in the measurement value storage unit 15 for a predetermined number of times, the individual determination value creation unit 17 sends the measured value to the failure history analysis unit 18 to the elevator monitoring terminal 3. The measured value of the elevator monitoring terminal 3 requires individual setting of the determination value because there is no failure history related to the measured value during a predetermined number of consecutive out of the determination value range and the measurement value does not vary. Is detected. The individual determination value creation unit 17 that has determined that the measurement value requires individual setting of the determination value calculates the average value of the measurement value of the elevator monitoring terminal 3 as the individual average value 17a, and from the measurement value storage unit 15 to the elevator The average value of the measured values of the elevator monitoring terminal that monitors the elevator having the same specifications as the elevator monitored by the monitoring terminal 3 is calculated as the standard average value 17b, and the difference between the individual average value 17a and the standard average value 17b is obtained. By adding this difference to the standard determination value of the measurement value, an individual determination value to be set individually is calculated and stored in the individual determination value storage unit 19.

  Subsequently, the individual determination value generation unit 17 sets the individual determination value 19a stored in the individual determination value storage unit 19 in the elevator monitoring terminal 3 using the determination value generation unit 11 and the communication unit 13, and thereafter the elevator. When the determination value is set to the monitoring terminal 3, the individual determination value 19a stored in the individual determination value storage unit 19 is used.

It is a block diagram of the elevator monitoring center apparatus concerning one Embodiment of this invention.
