Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator abnormality data collecting device for collecting elevator operation data and the like when the elevator becomes abnormal.

[0002]

2. Description of the Related Art In a conventional elevator abnormal data collection device, when an elevator is in a state different from a normal state, data related to the elevator is written and stored in a storage unit. FIG. 3 shows an example of the data. In the case of the data shown in the figure,
The date and time when the abnormality occurs, the code that codes the details of the abnormality, the floor if the abnormality is related to the floor, and the measurement value related to the abnormality are shown. Here, the measured value is
If the traveling speed is abnormal, the traveling speed is used. If the acceleration is abnormal, the acceleration is used. If the door is opened / closed abnormally, the opening / closing speed of the door, the operating time of each SW when the door is opened / closed, and the like.

Then, the monitoring center periodically reads out the operation data stored in the storage unit of the terminal device, for example, once a month. The maintenance staff decides the next inspection content by referring to the read data. For example, if data on doors is collected, the doors on the floor where an abnormality has occurred are focused on. Thus, from the collected data,
At the next inspection, the points to be inspected can be determined, and an efficient inspection plan can be created. By such inspection, parts can be replaced or adjusted before a failure such as an elevator stop, and the failure can be prevented.

[0004]

However, in the above-mentioned prior art, the number of data stored in the storage unit of the terminal device is limited by the size of the storage unit and is finite. Therefore, if there are frequent elevator abnormalities and the amount of accumulated data is large, and the free space of the storage unit is exhausted before the monitoring center reads the data, even if a data abnormality occurs thereafter. The operation data of the elevator at the time of abnormality cannot be stored in the storage unit. In this case, despite the elevator being abnormal, maintenance personnel did not know that it was abnormal at the next inspection,
There is a possibility that inspection may be overlooked, which is a problem.

Therefore, in order to prevent the amount of data to be stored from exceeding the capacity of the storage section, there is a method of increasing the capacity of the storage section, but this is a problem because of high cost. Also,
There is a method of shortening the interval at which the monitoring center reads the data accumulated in the storage unit, but this increases the load on the monitoring center, resulting in a decrease in the number of monitoring centers that can be monitored, which is a problem. Further, if a telephone line is used as the communication line between the monitoring center and the terminal, the telephone charge will increase, which is a problem.

An object of the present invention was made in view of the above problems, and even if an elevator is frequently abnormal, it is possible to retain all the data at the time of abnormality regardless of the capacity of the storage unit. To provide a device for collecting abnormal data.

[0007]

In order to achieve the above object, the present invention provides a data collecting means for collecting data relating to an abnormality when an abnormality occurs in an elevator, and the data collecting means. A terminal device comprising a storage unit for storing data, and an elevator abnormal data collection device comprising a monitoring center for monitoring the elevator and periodically taking out the data stored in the storage unit, in the terminal device, Capacity detecting means for detecting that the capacity of the storable area of the storage unit has decreased below a predetermined capacity, and to the monitoring center when the capacity detecting means detects that the capacity has decreased below a predetermined capacity. And a notification means for notifying the monitoring center, and when the monitoring center receives a notification from the notification means, it stores the information in the storage unit of the terminal device. It is provided with a reading means for reading data.

[0008]

When the free space in the storage unit of the terminal device becomes less than or equal to the predetermined capacity, the reporting means reports this to the monitoring center, and the monitoring center reads the data stored in the storage unit by the notification. As a result, it is possible to collect all elevator abnormality data even if elevator abnormality occurs frequently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Here, FIG. 1 is a block diagram showing the configuration of the embodiment, and FIG. 2 is a flow chart showing the operation of the embodiment.

As shown in FIG. 1, the output terminal of the elevator control panel 1 for controlling the operation of the elevator is connected to the control unit 21 of the terminal device 2, and the operation data of the elevator is constantly read and monitored. . When the operation of the elevator is abnormal, the control unit 21 writes the operation data of the elevator related to the abnormality in the storage unit 22 and stores the operation data. The communication unit 23 is connected to the control unit 21, and the communication line 3
It is also connected to the monitoring center 4 via. In addition, the monitoring center 4 stores the data accumulated in the storage unit 22,
It is read via the communication line 3, the communication unit 23, and the control unit 21.

Next, the operation of the embodiment having such a configuration will be described. While the elevator is operating, the control unit 2 of the terminal device 2
1 monitors the elevator operation data that changes with time from the elevator control panel 1 (step S1), and when the elevator is in an abnormal state, writes the operation data related to the abnormality in the storage unit 22 (step S2). Then, at this time, the control unit 21 determines whether or not the free space of the storage unit 22 is less than or equal to a predetermined capacity (step S3). When it is determined that the storage capacity is less than or equal to the predetermined capacity, the control unit 21 notifies the monitoring center 4 from the communication unit 23 via the communication line 3 that the free space in the storage unit 22 is less than or equal to the predetermined capacity ( Based on the notification, the monitoring center 4 reads the data accumulated in the storage unit 22 from the communication unit 23 via the communication line 3 (procedure S4) (procedure S5). The control unit 21 also erases the data accumulated in the storage unit 22 after the monitoring center 4 reads the data accumulated in the storage unit 22.

On the other hand, at the monitoring center 4, the received data is shown to the maintenance staff in charge of the elevator and referred to for the next inspection. Then, the maintenance staff focuses on the part corresponding to the abnormality. Of course, the monitoring center 4 also has a function of periodically taking out data from the storage unit 22 of the terminal device 2, and even if the free space of the storage unit 22 does not fall below a predetermined capacity, the storage unit 22 can be accessed via the communication line 3. Can receive data from.

As described above, in the present embodiment, even if the elevator is abnormally frequent, regardless of the capacity of the storage unit, all the data at the time of abnormality is stored in the storage unit, and the monitoring center reads all the data. The effect is that you can.

[0014]

As described above, according to the present invention, when the free space of the storage unit of the terminal device becomes less than a predetermined value, the storage center is notified of this and the monitoring center reads the data stored in the storage unit. As a result, even if there are many abnormal elevators, regardless of the capacity of the storage unit, all the data at the time of abnormality can be stored in the storage unit, and all the operation data of the elevator at the time of abnormality can be collected. Also, there is no need to increase the capacity of the storage unit, and there is no need to shorten the interval at which the monitoring center reads out the data stored in the storage unit.
