DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator abnormal data storage device for judging the presence or absence of an abnormality on the basis of an elevator control signal or the like and storing data determined to be abnormal.

[0002]

2. Description of the Related Art When an abnormality occurs in an elevator, a situation arises in which the operation of the elevator must be stopped.
Not only does it cause a great deal of inconvenience to people entering and exiting the building, but depending on the extent of the anomaly, it can lead to personal injury. For this reason, elevators constantly collect various operation data, and based on these data, the presence or absence of abnormalities is monitored,
When an abnormality occurs, prompt and appropriate measures are taken. Further, data related to the abnormality among the collected data is accumulated and used for analyzing the cause of the abnormality.

FIG. 3 is a block diagram of a conventional abnormal data storage device. In the figure, reference numeral 1 denotes an elevator control device for controlling the operation of an elevator, which stores various data relating to the state and operation of the elevator, and stores data related to an abnormality when an abnormality occurs during the operation of the elevator. Reference numeral 2 denotes an abnormal data storage device that stores abnormal data when there is an abnormality in the data of the elevator control device 1. The data collection device 21 periodically collects data stored in the elevator control device 1. An abnormality occurrence detection device 22 for determining the error, a data transfer device 23 for transferring data when there is an abnormality, and a storage unit 24 for storing data when there is an abnormality. The storage unit 24 includes a plurality of storage areas (eight in the figure) 241 to 24
8

Various data stored in the elevator control device 1 is periodically collected by a data collection device 21. The abnormality occurrence detection device 22 determines whether there is an abnormality in the elevator based on the data collected by the data collection device 21. If no abnormality is detected, the data collection device 21 collects new data in the next cycle in place of the currently collected data. When the abnormality occurrence detecting device 22 determines that there is an abnormality, the abnormality occurrence detecting device 22 sends the data collection device 21 to the data transfer device 23.
Is output to the storage device 24. The data transfer device 23 transfers the data to the storage device 24 by this output. There are various modes of data transfer to the storage unit 24 by the data transfer device 23.
As an example, when the first data is transferred to the area 241 and the next data to be transferred occurs, the first data is transferred to the area 2.
After transfer to the area 42, new data is transferred to the area 241, and thereafter, the same processing is sequentially repeated. Separately, the first data is stored in the area 241.
The next data is sequentially transferred to the area 242, and when the next data is generated with the data stored in the area 248, the data in the area 241 is erased, the data is stored in this area, and the next data is generated. There is also a mode in which the deleted data is stored by erasing the data in the area 242.

[0005] The data stored in the storage device 24 in this manner is transferred to a failure analysis device via a transmission line, or recorded on an IC card or the like by a collection device carried by a maintenance worker. Input to the failure analysis device via The failure analysis device analyzes the cause of the failure based on the input data and instructs a countermeasure.

[0006]

When an abnormality (failure) occurs in the elevator, it is necessary to determine the cause of the failure so as to prevent the abnormal state from occurring again, and to take measures to prevent recurrence. There are various types of failures that occur in this elevator.For example, a minor failure occurs continuously after a major failure occurs, or a major failure occurs after a series of minor failures occurs. And the like.

As described above, the most useful in determining the cause of a failure in an elevator having several modes of failure occurrence is to analyze the initial state of the failure occurrence. When investigating the cause of the above, it is necessary to analyze the state data at the early stage of the occurrence of the failure, and it is very important to save the data. However, in the method described in the prior art, if a failure state continues one after another, the initial failure data is erased and new data is stored, so that the initial failure data is stored. There is a problem that the possibility of losing the failure data is extremely large.

An object of the present invention is to solve the above-mentioned problems in the prior art and to provide an abnormal data storage device for an elevator which can prevent loss of initial failure data.

[0009]

In order to achieve the above object, the present invention is to periodically read operation data obtained from an elevator control unit by a data collection unit, and determine whether there is an abnormality in the elevator based on the data. The elevator abnormal data storage device stores the data when the abnormality is detected and stores the data at the time of the abnormality.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a block diagram of an abnormal data storage device for an elevator according to an embodiment of the present invention. In this figure, the same or equivalent parts as those shown in FIG. Reference numeral 220 denotes an abnormality detection / counter management device, which determines the presence / absence of an elevator abnormality based on data on the status and operation of the elevator among the data periodically collected by the data collection device 21 and sends the data to the data transfer device 230. It instructs the transfer of the collected data, manages the counter data for designating the data transfer destination (described later), and outputs the counter data. 230
Is the data collection device 2 based on the command and the counter data given from the abnormality detection / counter management device 220.
1 is a data transfer device that transfers the collected data to a storage area (described later) of a specified storage unit. Numerals 25 and 26 are storage units for storing the above-mentioned set data when a failure occurs, each of which has a plurality of storage areas (four in the figure).
251 to 254 and 261 to 264. Storage unit 25
Are stored in the storage areas 261 to 26 of the storage unit 26.
Reference numeral 4 denotes an area for storing aggregate data of the fifth and subsequent failures that have occurred.

FIG. 2 is a flowchart showing the operation of the failure data storage device of the elevator. The elevator control device 1 controls the operation of the elevator, and has control signals, data indicating the state of the elevator, and the like.
The data collection device 21 periodically reads the signals and data of the elevator control device 1 (procedure S ₁ shown in FIG. 2).

If no data is stored in the storage units 25 and 26 and the counter of the abnormality detection / counter management device 220 is zero, and a failure occurs in the elevator, the abnormality detection / counter management device 220 collecting apparatus 21 abnormal elevator by the collected aggregate data, it is determined that the generated (Step S _2), and counts up (+1) counter indicating a transfer destination of data (Step S _3). The abnormality detection / counter management device 220
It is checked whether the value of the counted-up counter is larger than the number 8 in the storage area (step S ₄ ). In this case, since the value of the counter is 8 or less, the processing in step S ₅ is skipped and the data transfer device 230 is Te data transfer command signal and the counter data (in this case, the counter data from a first failure data "1") to (Step S _6).

This output allows the data transfer device 230
Is an area 2 in the storage unit 25 which is an area corresponding to the counter data "1" in the data collection device 21.
Transfer to 51. Thereafter, when a failure occurs several times, the counter data is counted up each time, and the collected aggregate data is stored in the storage unit 25 according to the counter data.
Areas 252 to 254 and areas 261 to 26 of the storage unit 26
4 are sequentially stored.

When eight failures occur, the area 2
If a further failure occurs in a state where the data is stored up to 64, the above counter data becomes larger than 8, and this is determined by the procedure S.
_The abnormality detection / counter management device 220 reduces the counter data by 4 (step S4).
₅ ) Since the data transfer command signal and the counter data are transmitted to the data transfer device 230, the data transfer device 230
Deletes the data stored in the area 261 of the storage unit 26 corresponding to the counter data (in this case, “5”) and stores new aggregate data. Thereafter, even if a failure occurs several times, and new aggregate data is transferred to the storage unit each time, the new data is sequentially stored in the areas 262 to 264 of the storage unit 26 corresponding to the counter data. The data in the storage unit 25 is not updated unless the counter data is cleared.

The data stored in the storage units 25 and 26 is transferred to a failure analysis device via a transmission line, or recorded on an IC card or the like by a collection device carried by a maintenance worker. When the counter data is cleared, the counter data is also cleared at the same time, so that when a failure occurs and new data is stored in the storage unit, the new data is stored sequentially from the area 251 of the storage unit 25 again.

In this way, the storage unit for storing data is classified, and the configuration is such that data relating to the first four occurrences and the last four failures remains, so that failure analysis can be performed. Thus, the latest data on the failure can be obtained at the same time without erasing data such as the operating state and control state of the elevator in the early stage of the failure occurrence.
