Description

The present invention, by leaving the failure analysis operation condition data recording elevator required when failure over a long period, it relates to a failure analysis equipment elevator which facilitates a specific failure point.

In the conventional failure analysis function of an elevator, operation histories (signal states) for several cycles before and after the occurrence of a failure are stored. Therefore, when performing failure analysis, since analysis is performed only with operation history (signal state) data for several cycles, there are many cases where analysis with high accuracy cannot be performed.
In addition, the conventional failure analysis function is used for each product software (hereinafter abbreviated as S / W) of an elevator, for example, any S / W, control S / W, drive S / W, etc. Since / W detects a failure and simultaneously records an operation history (signal state) at the time of the failure, there are many cases where information that is actually desired is not recorded, and high-precision analysis cannot be performed. That is, actually, failure detection is performed separately for each product S / W, but recording is performed at different failure data timings.
When this is shown in a time chart, it is as shown in FIG. 6, for example. In the figure, 50 is the control S / W for each unit, 60 is the control S / W, 70 is the drive S / W, 80 is the maintenance S / W, A1 to E1 are the failure detection points of each S / W, and A2 to E2 are The failure codes at each failure detection point generated by the maintenance S / W 80 analyzing the operation status data, and A3 to E3 are recorded as the self-diagnosis history of the failure codes generated by the maintenance S / W.
Each S / W 50, 60, 70 detects a failure at the failure detection points A1 to E1, and the maintenance S / W 80 collects (records) operation status data of the management S / W 50, the control S / W 60, and the drive S / W 70. Then, the operation status data collected by the maintenance S / W 80 is analyzed to generate the failure codes A2 to E2, and the failure codes A2 to E2 generated by the maintenance S / W 80 are recorded as records A3 to E3 as the self-diagnosis history. . When the next failure is detected, the operation status data is overwritten and recorded.
In the example of FIG. 6, there are a total of five failures that occur in one run, but in most cases, the operation status data at the time of failure that the maintenance staff actually wants to check is “Record A3”. However, the operation status data at the time of failure that is finally recorded is often “record E3” and is not related to the actual cause of failure. This is because a large amount of recording area cannot be secured because of elevator resources. In addition, depending on the failure that requires detailed data at the time of failure, since necessary data does not remain, it takes time to identify the failure location and to confirm the phenomenon. In addition, in the case of a failure that occurs repeatedly, data with the same contents is recorded many times, and there is a high possibility that other failure data is erased by overwriting. Further, since it is a history at the point of failure, the subsequent operation of the elevator is not known, and it cannot be grasped even if other phenomena occur.

  Also, as an existing technology, an elevator abnormality data storage device has been proposed in which the operation state and control state data of an elevator at the initial stage of failure occurrence, which is important when analyzing a failure, are not erased (for example, Patent Document 1). reference).

JP-A-6-239547

With the conventional elevator failure analysis function, depending on the failure that requires detailed data at the time of failure, since necessary data does not remain, it takes time to identify the failure location and to confirm the phenomenon. In addition, in the case of a failure that occurs repeatedly, data with the same contents is recorded many times, and there is a high possibility that other failure data is erased by overwriting. Further, since it is a history at the point of failure, the subsequent operation of the elevator is not known, and it cannot be grasped even if other phenomena occur.
Moreover, in the thing of patent document 1, since it is only made to remain the data regarding the failure which occurred for the first time, for example 4 times, and for the last 4 times, for example, the failure detection function is divided | segmented into each product S / W. Thus, there is no mention of performing fault detection with high accuracy.

Software detects a failure at each failure detection point, and the first maintenance software stores a failure code at each failure detection point and collects operation status data at each failure detection point. The data collected first for each software is recorded .

  According to the present invention, since the operation status data of the elevator at the time of occurrence of a failure necessary for failure analysis remains, it is possible to reduce the time required for the work for identifying the failure location and the phenomenon confirmation work.

Next, the operation of the elevator failure analysis apparatus will be described with reference to FIGS.
First, the operation flow of the elevator operation control apparatus 1 in the elevator failure analysis function will be described with reference to FIG. In order to generate the operation status at the time of an elevator failure in step S1, the elevator operation data generation unit 112 at the time of the failure traces the elevator operation data, and in step S2, the failure detection unit 113 detects the failure of the elevator. In step S 3, each product S / W 11 writes the failure detection status in the state monitoring interface unit 32. In this state, when a failure is detected in step S4, the process proceeds to step S5, each product S / W 11 writes the failure detection content in the state monitoring interface unit 32, and further proceeds to step S6, where each product S / W 11 Elevator operation data at the time of failure is written in the RAM unit 31.
Next, the operation flow of the first maintenance S / W2 and the second maintenance S / W4 in the elevator failure analysis function will be described with reference to FIG. In step S <b> 11, the state monitoring unit 21 monitors the contents of the state monitoring interface unit 32. When the content of the state monitoring interface unit 32 changes in step S12, the process proceeds to step S13, and the failure detection data acquisition unit 211 acquires the failure detection content written in the state monitoring interface unit 32. And the elevator operation data acquisition part 212 acquires the elevator operation data at the time of failure written in the RAM part 31 by step S14. Next, in step S15, the self-diagnosis history generation unit 221 generates a self-diagnosis history based on the failure detection content acquired by the failure detection data acquisition unit 211. In step S16, the self-diagnosis history generated by the self-diagnosis history generation unit 221 and the failure-time elevator operation data acquired by the elevator operation data acquisition unit 212 are transferred to the second maintenance S / W. In step S <b> 17, the self-diagnosis history and the failure-time elevator operation data transferred from the failure-time data recording processing unit 222 are recorded in the self-diagnosis history recording unit 411 and the elevator operation data recording unit 412 of the failure-time information recording unit 41. As a result, the situation at the time of failure occurrence can be confirmed in more detail, the degree of understanding of the situation at the time of failure occurrence is increased, and the response time for failure recovery is shortened.
Next, the operation flow of the data display terminal 5 in the elevator failure analysis function will be described with reference to FIG. In step S21, the data display terminal 5 requests data reference to the data display terminal interface unit 42 of the second maintenance S / W4. In step S22, the data display terminal 5 passes through the data display terminal interface unit 42. Get the data. In step S23, the data display terminal 5 displays the data recorded in the self-diagnosis history recording unit 411 and the elevator operation data recording unit 412. This makes it possible to use the detailed data at the time of the failure to visually represent a graph of the situation at the time of occurrence, making it easier to explain the situation report to the customer, etc. The level of understanding also improves.

Next, a recording operation by the elevator failure analysis apparatus will be described with reference to a time chart shown in FIG. In the figure, 50 is a management S / W for each unit, 60 is a control S / W, 70 is a drive S / W, 90 is a first maintenance S / W, A1 to E1 are failure detection points of each S / W, A2 ~ E2 is the failure code at each failure detection point A1 to E1 recorded by the first maintenance S / W90, F is the first maintenance S / W90 collected and recorded the operation status at each failure detection point A1 to E1 It is generated and recorded as a self-diagnosis history together with the fault codes A2 to E2.
First, the first maintenance S / W 90 starts recording at the start of elevator travel, and each S / W 50, 60, 70 detects a failure at the failure detection points A1 to E1. The first maintenance S / W 90 records the failure code A2 at point A1, and the first maintenance S / W 90 collects operation status data at point A1. Next, the first maintenance S / W 90 records the failure code B2 at the B1 point, and the first maintenance S / W 90 collects the operation status data at the B1 point. Hereinafter, similarly, the first maintenance S / W 90 records the failure code C2 at the point C1, the first maintenance S / W 90 collects the operation status data at the point C1, and the first maintenance S / W 90 receives the D1. The failure code D2 at the point is recorded, the first maintenance S / W 90 collects the operation status data at the point D1, the first maintenance S / W 90 records the failure code E2 at the point E1, and the first maintenance S / W90 collects operation status data for E1 point. Thereby, since one driving | running | working (one event) was complete | finished, 1st maintenance S / W90 complete | finishes recording, 1st maintenance S / W90 produces | generates a self-diagnosis log | history, and records operation status data. As a recording condition, data collected first for each product S / W within one event (one run) is recorded. In the example of FIG. 5, the data is collected at points A1, B1, and E1. This is because the failure that occurred first is considered as the cause of the failure.

  As described above, according to the first embodiment, since the elevator operation status data at the time of occurrence of a failure necessary for failure analysis remains, it is possible to shorten the time required for the work for identifying the failure location and the phenomenon confirmation work. Further, by recording the history of the failure as a failure code, it becomes easier to analyze not only the instantaneous situation but also the subsequent failure situation. Conventionally, even if a failure status remains as a history, the history has not been known unless the history is confirmed. However, in the first embodiment, the history is recorded in one history. No waste. Even in the case of a failure that occurs repeatedly, unnecessary data is not recorded because it is recorded within one event.
