Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator abnormality data storage device for collecting and storing data relating to an abnormality when an abnormality occurs in the elevator.

[0002]

2. Description of the Related Art An elevator installed in a building is used by a large number of people who enter and exit the building. Therefore, when an abnormality occurs in the elevator that hinders the operation of the elevator, many people may be inconvenienced and personal injury may occur. For this reason, the elevator control device always takes in the operation status of the elevator, stores these data, and determines the presence or absence of abnormality based on the data. In this case, since the data taken in by the control device is sequentially erased from the old data, the control device is in a state where the data is stored for a relatively short time.

Japanese Patent Application Laid-Open No. 4-68563 filed by the applicant of the present invention as a conventional technique stores the operation status and control data for a certain period of time before and after the abnormality is detected when an abnormality is detected in the elevator. Then, a method of reading those data through a communication line and confirming them on a time chart is described. FIG. 3 is a time chart in which data is collected and plotted by the conventional technique. As shown in FIG. 3, in addition to the speed curve of the car and the operating states of various switches, various signal data for controlling an elevator (not shown) are plotted in a time chart over a certain period of time. By analyzing this drawing, it has become possible to identify the cause of the failure and to determine the failed part.

[0004]

Generally, the maintenance and inspection work of an elevator is sometimes performed by inspecting and servicing the equipment by performing various operations that cannot occur in normal operation of the elevator. Most of them are performed by operating maintenance switches that are often used during maintenance work, switches on the operation panel on the car in the car, and switches on the operation panel in the control panel. By the way, in the above-described conventional elevator abnormal data storage device, since the state of the elevator is constantly monitored, it is always connected to the elevator. For this reason, in order to prevent the abnormal data storage device from unnecessarily storing artificial data by performing the maintenance inspection work as described above, abnormality detection is performed when the maintenance switch is turned on. Designed not to.

However, the maintenance and inspection work of the elevator is not limited to the work which can be performed with the maintenance switch and the like turned on all the time, and sometimes the maintenance switch must be turned off. In such a case, the abnormal data storage device may detect an abnormality and accumulate data. When the engineer analyzes the data accumulated in this way at a later date, the data at the time of failure detection shows that the maintenance switch etc. is off, but from the data before and after that, for example, the operation switch in the control panel It becomes clear that the operation is performed, that is, it becomes clear that the maintenance and inspection were performed at the time of detecting the abnormality, and therefore it is determined that the abnormality is due to the maintenance and inspection work.

As described above, the data artificially generated during maintenance and inspection work is less important than the data generated during normal operation, but such artificial data registration is not possible. If it is done frequently, there is a risk that the limited capacity of the storage unit will be lost and it will not be possible to store important data generated during normal operation.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide an abnormal data storage device for an elevator capable of preventing the capacity of a storage unit from being lost due to artificially generated data of low importance. To provide.

[0008]

In order to achieve this object, the present invention has an elevator having a data collecting section for collecting data relating to an abnormality that has occurred in an elevator and a storage section for storing the collected data. In the abnormal storage device, the temporary storage unit that temporarily stores the data collected by the data collection unit, and the data that determines whether the data stored in the temporary storage unit is artificially generated. The analysis unit and the data transfer unit that transfers the data determined by the data analysis unit to be non-artificial to the storage unit are provided.

[0009]

Since the present invention is configured as described above, when the data collecting unit collects data relating to an abnormality that has occurred in the elevator, the data is temporarily stored in the temporary storage unit. Then, the data analysis unit reads the data stored in the temporary storage unit, and determines whether this data is data artificially generated by maintenance work or data generated during normal operation of the elevator. to decide. Then, based on this determination, only the data generated during the normal operation of the elevator is transferred to the storage unit by the data transfer unit and stored. As a result, it is possible to prevent the capacity of the storage unit from being lost due to artificially generated less important data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an elevator abnormal data storage device according to the present invention will be described below with reference to the drawings. 1 is a block diagram showing an embodiment of an abnormal data storage device for an elevator according to the present invention, and FIG. 2 is a flowchart showing a processing procedure of the abnormal data storage device.

Generally, as shown in FIG. 1, an elevator generally comprises a car 2 and a counterweight 3 which are connected to each other in a slip way via a rope 1, and sheaves 4 and 5 on which the rope 1 is wound. The control device 6 for controlling the entire elevator, the control panel operation panel 61 installed on the microcomputer board in the control panel 6, and the car 2
It has operation panels 21 and 22 that are respectively provided on the top and the inside and are operated during maintenance and inspection work, and a control cable 7 that electrically connects the car 2 and the control panel 6. In addition, each of the operation panels 21, 22, 61 has a maintenance switch (not shown) for setting a low speed operation mode for maintenance work and various other switches built therein.

The abnormal data storage device 8 of the present embodiment provided in such an elevator monitors the data of the control device 6 and outputs a data collection command signal when there is an abnormal condition, and an abnormal detection part 81, The data collection unit 82 that collects data relating to an abnormality that has occurred in the elevator, the temporary storage unit 83 that temporarily stores the data collected by the data collection unit 82, and the data stored in the temporary storage unit 83 are artificial. It is determined that it is not artificial by the data analysis unit 84, which determines whether or not the data has occurred, and outputs a data transfer command based on the determination to instruct the data transfer destination. Data transfer unit 85 for transferring the stored data to one of the storage units described later.
And a storage unit 86 that stores data determined by the data analysis unit 84 to have occurred due to an abnormality during normal operation of the elevator, and a data storage unit 86 that stores data determined to be artificial by the data analysis unit 84. The storage unit 87 is provided.

Now, it is assumed that the maintenance worker enters the machine room for the inspection work and performs necessary operations on the operation panel 61 of the control panel 6 before the inspection work. This inspection work situation is the car 2
It should be performed in the same state as normal operation without turning on the maintenance switches of the upper operation panel 21, the operation panel 22 in the car 2 and the operation panel 61 of the control panel. When any abnormal state occurs during such work, and the abnormality detection unit 81 detects this abnormality, the abnormality detection unit 81 outputs a data collection command to the data collection unit 82. The first data collection 82 collects data according to a predetermined data type and data collection time from the control device 7, and the collected data is stored in the temporary storage unit 8.
Remember in 3.

When data collection is completed and a set of data is stored in the temporary storage unit 83, the data analysis unit 84 analyzes the data. First, in step S1, the data related to the operation panel 21 in the temporary storage unit 83 is checked from the start of collection of data to the end of collection, and the maintenance switch of the operation panel 21,
Also, determine whether or not there is any artificial operation on the other switches. However, here, since each switch of the operation panel 21 is not operated, it is determined that there is no operation. Next, as step S2, the operation panel 22 in the temporary storage unit 83
The data related to the above is checked from the start of data collection to the end of data collection, and it is determined whether or not an artificial operation is found on the maintenance switch of the operation panel 22 and other switches. However, similarly to the above, since the switches of the operation panel 21 are not operated here, it is determined that there is no operation.

After that, the data analysis unit 84 is step S here.
As data 3, data regarding the operation panel 61 in the temporary storage unit 83 is checked from the start of data collection to the end of collection. At this time, since the operation panel 61 in the control panel 6 is operated in the preparatory stage before the work, the supplemented data is plotted before the control panel 61 is detected before the abnormality is detected as in the case shown in FIG. Changes appear in the maintenance switch data. It is determined that the change in the data is not instantaneous but artificial, and the process proceeds to step S5. This step S5 is a process performed when it is determined that the supplemented data is artificial, and the data analysis unit 84 causes the data transfer unit 85 to transfer the data to another storage unit 87. And send the data transfer command. The data transfer unit 85 transfers the data to another storage unit 87 which stores the artificial data based on the designation.

On the other hand, when an abnormality occurs during normal operation, when the abnormality is detected, the maintenance worker does not perform any operation before and after the abnormality is detected. Therefore, each switch of the operation panel as shown in FIG. No change is seen. Therefore, in step S3 described above, the data analysis unit 84 determines that "no operation" and proceeds to step S4. In step S4, the data transfer destination is designated as the storage unit 86 that stores the data during normal operation. And outputs a data transfer command, and the data transfer unit 85 transfers the data to the storage unit 86 based on this data transfer command.

In the embodiment configured as described above, the data detected by the abnormality and collected is temporarily stored in the temporary storage unit 83, and the data captured by the data analysis unit 84 indicates whether or not the data has changed due to an artificial operation. By categorizing the storage units that store data based on this, the capacity of the storage unit is occupied by the data that is artificially generated by maintenance work, and more importantly, regarding abnormalities that occur during normal operation. It is possible to prevent a situation in which data cannot be stored thereafter.

In this embodiment, another storage unit 87 is provided to store the artificially generated data. However, the present invention is not limited to this, and the other storage unit 87 is not provided. The data generated in a specific manner may not be stored.

[0019]

Since the present invention is configured as described above, it is possible to prevent the capacity of the storage unit from being lost due to artificially generated data of low importance. As a result, it is possible to surely store the highly important data generated during the normal operation, and thus it is possible to monitor the elevator with higher reliability. Further, by providing another storage unit for storing the artificially generated data, all the detected data can be confirmed.
