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. 2 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 the elevator, which stores various data relating to the state and operation of the elevator, and data relating to the abnormality when an abnormality occurs during the operation of the elevator and the importance of the abnormality. The marker data indicating the degree is stored. 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 has a plurality of storage areas (eight in the figure) 241-248.

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 detection device 22 determines that there is an abnormality, the abnormality occurrence detection device 22 outputs a command to move the data collected by the data collection device 21 to the data transfer device 23. The data transfer device 23 stores the data thus transferred in the storage device 24.
Transfer to There are various modes of data transfer to the storage unit 24 by the data transfer device 23. As one 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 242. After transferring to
There is a mode in which new data is transferred to the area 241 and the same processing is sequentially repeated thereafter. Also, apart from this,
The first data is stored in the area 241 and the next data is stored in the area 242.
When the next data is generated while the data is stored up to the area 248, the data in the area 241 is erased and the data is stored in this area. There is also a mode in which data is erased and stored.

[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]

There are two types of elevator abnormalities (failures) that need to be dealt with promptly (major failures) and those that have no adverse effect even if left for a while (light failures). These failures have various modes of occurrence. For example, minor failures occur successively after a major failure occurs, or conversely, major failures occur after a series of minor failures. However, in any case, the number of times that a minor fault occurs is far greater than the number of times that a major fault occurs.

By the way, in the above prior art, the storage device 2
4 is a transfer mode in which old data is erased and new data is stored, so that the storage device 24 stores a large amount of data of minor faults, which is important for failure analysis. There is a problem that the possibility of data loss is extremely high.

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 capable of preventing the loss of data of a serious failure.

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 determination / rank processing device, which is sign data indicating the occurrence of an abnormality during operation of the elevator among data periodically collected by the data collection device 21 and a sign indicating the importance of the abnormality. It determines that an abnormality has occurred due to data or the like, instructs the data transfer device 230 to transfer the collected data, and also outputs data designating a data transfer destination (described later). 230 is a data collection device 2 based on the command and data given from the abnormality determination / rank processing device 220.
1 is a data transfer device that transfers the collected data to a storage area (described later) of a specified storage unit. 25 is a storage unit for storing data when a major failure occurs, and 26 is a storage unit for storing data when a minor failure occurs. A plurality of storage areas (four in the figure) 251 to 254 and 261 are respectively provided. To 264.

The elevator control device 1 has a function of controlling the operation of the elevator, and determines that an abnormality has occurred based on control signals obtained during the operation control, data representing the state of the elevator, and the like. It has a function of storing sign data indicating occurrence, data relating to a failure when an abnormality has occurred, sign data in which the degree of importance of the abnormality is classified according to a predetermined rank, and the like. The data collection device 21 periodically reads data related to the failure of the elevator control device 1 and each sign data.

Now, when no data is stored in the storage units 25 and 26, if a serious failure occurs in the elevator, the elevator control apparatus 1 sets the sign data indicating the occurrence of the abnormality and the importance of the abnormality. Are generated, and these tag data are read out to the data collection device 21 together with other various data. The abnormality judging / rank processing device 220 judges that an abnormality has occurred based on the sign data indicating the occurrence of the abnormality in the aggregate data collected by the data collecting device 21, and further, based on the sign data indicating the importance of the abnormality. Determine the significance of the anomaly. In this case, since the failure is serious, the importance of the abnormality is high, and therefore, the abnormality determination / rank processing device 22
Outputs a command to transfer the collected set data to the storage unit 25 side. By this command, the data transfer device 230 stores the aggregated data in the first area 25 of the storage unit 25.
Transfer to 1. Thereafter, when a further serious fault occurs, data relating to this is stored in the next area 252 according to a similar procedure.
When the storage up to the area 254 is completed in this way, the data of the next major fault is erased from the area 251 and stored in this area, and the next data is erased from the area 252. The same processing is repeated thereafter.

Next, when a minor failure occurs in the elevator, sign data indicating that an abnormality has occurred in the elevator control device 1 and sign data indicating the importance of the abnormality are created in the same manner as in the case of the severe failure described above. These tag data are read out to the data collection device 21 together with various data. The abnormality determination / rank processing device 220 determines that an abnormality has occurred. In this case, since the sign data indicating the importance of the abnormality indicates a low rank, the collected aggregate data is It outputs a command to transfer the data to the storage unit 26 side. By this command, the data transfer device 230 stores the aggregated data in the first area 2 of the storage unit 26.
Transfer to 61. Thereafter, when a minor failure occurs several times, the data of the failure is sequentially stored in the areas 262 to 264 of the storage unit 26 each time, and the area 264 is stored.
When light failure still in a state of being stored until occurs, new data erases data area 261 stores to this area, then data minor faults that have occurred to erase the data in the area 2 6 2 Store in this area.

As described above, in the present embodiment, the storage unit for storing data is classified into the storage unit 25 and the storage unit 26 according to the importance of the abnormality that has occurred, so that the data is first stored in the storage unit 25. The data at the time of occurrence of a major failure is not erased by the data of a minor failure that has occurred successively and many times thereafter, and the data at the time of occurrence of a major failure that is important during failure analysis can be left.

In the above embodiment, an example has been described in which the elevator control device 1 has a function of detecting an abnormality and creating sign data for classifying the importance of the abnormality. Judgment / rank processing device 2
20, it is determined that an abnormality has occurred in the elevator based on data for controlling the operation of the elevator among the data periodically read by the data collection device, and when the abnormality is determined, the abnormality is determined to be a predetermined abnormality. It is also possible to provide a function of classifying according to the rank of importance and outputting a command to transfer data to the storage unit corresponding to the rank.
