On the other hand, when the failure diagnosis device 4 located at a remote place receives the failure report, it supplies the operation data received after the failure report to the internal display unit and displays the operation data on the display screen. Display the contents of operation data. Then, the failure diagnosing person looks at the content of the operation data displayed on the display screen, determines the location of the abnormality of the elevator having the failure report, the content of the abnormality, the degree of the abnormality, etc. The decision is made as to whether or not a maintenance staff should be dispatched to the site of the elevator with the failure report.

[0008]

However, the above-mentioned conventional remote failure diagnosis device for an elevator transmits the operation data to the failure diagnosis device 4 side together with a failure report when the elevator operation is abnormal, and the operation data of the operation data is detected. Although the contents are displayed on the display screen of the failure diagnosis device and the failure diagnosing person sees the displayed contents, the location, contents, degree, etc. of the abnormality are judged. Since the operation data is only displayed, it cannot be directly compared with the corresponding operation data when the operation is normal on the display screen. For this reason, in the above-described conventional remote failure diagnosis device for an elevator, even if a failure diagnosing person makes a diagnosis, it may take a considerable time to analyze the operation data at the time of the operation abnormality. There is a problem in that a considerable amount of specialized knowledge may be required, and a large amount of time is spent in deciding whether to send a maintenance staff to the site or not.

The present invention is intended to solve the above-mentioned problems, and its object is to directly compare on the display screen the operation data at the time of abnormal operation and the corresponding operation data at the time of normal operation. An object of the present invention is to provide a remote failure diagnosis device for an elevator that facilitates analysis of operation data when an operation is abnormal.

[0010]

In the diagnostic device, a memory is coupled to the fault diagnostic device, and when the fault diagnostic device is not in communication, the predetermined operation data temporarily stored in the data collection device is transferred and stored in the memory via the communication line. , The predetermined operation data temporarily stored in the storage area and the corresponding operation data stored in the memory when the failure is reported. Is supplied to the display unit, by superimposing the both operations data in the display screen,
Means for diagnosing the fault condition of the elevator are provided.

[0011]

According to the above means, the data collecting device temporarily stores the predetermined operation data supplied from the elevator control device. However, when the failure diagnosis device is not communicating, the temporarily stored predetermined operation data is: After being read out, it is transmitted from the status monitoring device via a communication line to a memory coupled to the fault diagnosis device and stored therein.

In such a state, when the elevator control device detects an abnormal operation of the elevator and the condition monitoring device notifies the condition monitoring device side of the failure notification via the communication line, this failure notification is issued. Subsequently, the operation data (hereinafter, referred to as abnormal data) including the one at the time of the abnormal operation, which is temporarily stored in the data collection device, is transmitted to the failure diagnosis device side through the same communication line.

Upon receiving the notification of the failure report, the failure diagnosis device displays the abnormal data on its display portion and the operation data at the time of normal operation corresponding to the abnormal data already stored in the memory (hereinafter referred to as "operation data"). , Normal data) is supplied, and the abnormal data and the normal data are displayed on the display screen. At this time, the fault diagnosing person can directly compare the abnormal data with the normal data by performing an operation such as superimposing the abnormal data and the normal data screen simultaneously displayed on the same display screen. As a result, the failure diagnosing person can immediately analyze and judge the location, content, degree, etc. of the elevator operation abnormality, and can immediately decide the necessity of dispatching maintenance personnel. become able to.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an elevator remote failure diagnosis apparatus according to the present invention.

In FIG. 1, reference numeral 6 denotes a memory coupled to the failure diagnosis device 4, and other components that are the same as those shown in FIG.

The memory 6 is selected to have a storage capacity capable of storing the operation data sent from all the status monitoring devices 3 managed by the corresponding failure diagnosis device 4 for a predetermined period.

The elevator remote failure diagnosing device having the above-described structure operates as follows.

The elevator control device 1 controls the entire operation of the elevator. In addition, the elevator control device 1 performs a predetermined operation in the operation data acquired during the operation control of the elevator, for example, an operation of a departure command. The data indicating the operation of the stop command, the data indicating the open / closed state of the door, etc. are constantly supplied to the data collecting device 2, and the abnormality of the operation of the elevator is detected, and the abnormality information is displayed when the abnormality is detected. The operation of supplying the monitoring device 3 is exactly the same as that of the conventional elevator control device 1 shown in FIG. Further, the data collection device 2 temporarily stores the predetermined operation data supplied from the elevator control device 1 in the internal memory, and when the data storage amount exceeds the memory capacity, the old storage data is sequentially discarded. The point that the latest operation data is always temporarily stored is the same as the operation of the conventional data collection device 2 shown in FIG. Further, the state monitoring device 3 constantly monitors the presence / absence of the abnormality information supplied from the elevator control device 1. When the supply of the abnormality information is confirmed, the failure diagnosis device is operated by means such as automatic dialing. 4 is called, and the condition monitoring device 3 and the failure diagnosis device 4 are called.
When and are connected by the communication line 5, the state monitoring device 3
Notifies the failure diagnosis device 4 of the failure notification via the communication line 5 and reads the operation data temporarily stored in the data collection device 2, and the read operation data fails through the communication line 5. The transmission to the diagnostic device 4 is also the same as the operation of the conventional state monitoring device 3 shown in FIG.

In addition to the above-described operation, the present embodiment determines the time when the failure diagnosis device 4 is in the non-communication state, that is, the time when no status notification device 3 has issued a failure report. Then, the state monitoring device 3 reads the operation data temporarily stored in the data collection device 2, and transfers the read operation data to the failure diagnosis device 4 side via the communication line 5. On the other hand, when the failure diagnosis device 4 receives the operation data, it supplies the operation data to the connected memory 6 and causes the memory 6 to sequentially store the operation data. In this case, the period in which the failure diagnosis device 4 is in the non-communication state is considered to be considerably longer than the period in which the failure diagnosis device 4 is in the communication state. Therefore, the operation data temporarily stored in the data collection device 2 is frequently updated. Failure diagnosis device 4
When the internal memory of the data collection device 2 is full, there is no or very little operation data discarded in the internal memory. Of course, while the operation data is being transferred to the failure diagnosis device 4 side, any one of the status monitoring devices 3
When the failure diagnosing device 4 is notified of a failure by the operator, the transfer of the operation data is immediately stopped, and the operation data is transferred again after waiting for the failure diagnosing device 4 to be in the non-communication state. To do so. Further, in the memory 6, when the predetermined storage area is filled with the operation data transferred from the data collection device 2, the old operation among the operation data stored in the storage area is full. The data is sequentially discarded, and the memory 6 always stores only the relatively latest operation data.

In the state as described above, if the elevator control device 1 now detects an abnormal operation of the elevator,
The elevator control device 1 supplies the abnormality information to the state monitoring device 3. When the status monitoring device 3 receives this abnormality information,
The failure diagnosing device 4 is called by means such as automatic dialing, and when the status monitoring device 4 is called, a notification of failure is sent to the status monitoring device 4 via the communication line 5. At this time, the state monitoring device 3 operates the data collection device 2
The operation data temporarily stored in (the operation data indicating the operation abnormality is included in the operation data) (hereinafter, this is referred to as abnormal data again) is read, and the read abnormal data is referred to as the failure. Communication line 5 following notification
It is transmitted to the failure diagnosis device 4 side via.

On the other hand, when the failure diagnosis device 4 receives the failure report, the failure diagnosis device 4 supplies the abnormal data transmitted subsequently to the display unit and also stores in the memory 6 connected to the failure diagnosis device 4. The operation data corresponding to the abnormal data already stored (this operation data is only the operation data at the time of normal operation) (hereinafter, referred to as normal data again) is read from the normal data Is supplied to the display unit, and the abnormal data and the normal data are simultaneously displayed on the display screen of the display unit.

At this time, the fault diagnosing person performs an operation such as superimposing the abnormal data and the normal data which are simultaneously displayed on the display screen to directly connect the abnormal data and the normal data. It is possible to analyze the location, content, degree, etc. of the elevator operation abnormality from the result of the comparison immediately, and it is possible to immediately judge the elevator operation including the necessity of dispatching maintenance personnel. It is possible to immediately determine appropriate instructions and countermeasures for the abnormal operation of.

In the above-mentioned embodiment, the predetermined operation data stored in the data collection device 2 includes data indicating the operation of the departure command, data indicating the operation of the stop command, and the opening / closing of the door. Although the data indicating the state is described as an example, the predetermined one of the operation data in the present invention is not limited to the above-described example, and the content can be appropriately selected. It is a thing.

[0025]

As described above, according to the present invention, the operation data (normal data) at the time of normal operation of the elevator is stored in the memory connected to the failure diagnosing device to notify the failure report. Subsequently, the operation data (abnormal data) before and after the occurrence of the operation abnormality is transmitted to the failure diagnosis device, and the failure diagnosis device simultaneously displays the abnormal data and the normal data on the display screen of the display unit. Therefore, the fault diagnosing person can directly compare the abnormal data and the normal data with each other, and thereby, it becomes possible to immediately analyze and judge the location, content, degree, etc. of the elevator operation abnormality. Therefore, it is possible to immediately determine an appropriate instruction and countermeasure for the abnormal operation of the elevator, including the necessity of dispatching a maintenance staff.

Further, according to the present invention, since the operation data is transferred to the memory connected to the failure diagnosis device when the failure diagnosis device is not in communication, the abnormality is notified when the failure report is notified. Only the data needs to be transferred via the communication line, and the two operation data are displayed even though the two operation data of the abnormal data and the normal data are displayed on the display screen of the failure diagnosis device. There is also an effect that the time required for the operation can be shortened.
