Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is connected via a communication line to a data collection device for collecting operation data when an abnormality of an elevator is detected, and analyzes the operation data to determine the contents of the operation abnormality of the elevator from a remote place. The present invention belongs to the technical field of a remote abnormality diagnosis device for an elevator equipped with an abnormality diagnosis device for performing detailed diagnosis.

[0002]

2. Description of the Related Art Conventionally, when an abnormality in an elevator is detected by a sensor arranged at a key point of the elevator, the terminal device issues an alarm to a central monitoring station via a communication line. In this type of abnormality detection, the outline of the abnormality that has occurred in the elevator at the central monitoring station can be grasped, but detailed information such as detailed contents and degree of the abnormality cannot be obtained.

[0003] For example, Japanese Patent Laid-Open Publication No.
As disclosed in Japanese Unexamined Patent Application Publication No. 5-201643, the operation state of the elevator is constantly monitored, and when an operation abnormality is detected, operation data before and after the time is collected and stored in a memory. With the data collection terminal device to be stored, when the central monitoring station receives an abnormality alert, the elevator failure diagnosis device sends the operation data before and after the occurrence of the abnormal operation of the elevator in the abnormal state from the data collection terminal device via the communication line. By reading and reading, and converting the abnormal content into a display format that is easy to grasp, and displaying it on the display device, or displaying it on the display device in a display format that can be easily compared with the normal operation data, the abnormal content can be displayed. A technology has been developed which makes it possible to easily recognize the degree of anomalies and abnormalities.

[0004]

By the way, despite the fact that the data collection terminal device frequently generates the same content of abnormal data or that the same content of the abnormal data has been generated for a long time, the actual occurrence of a fault occurs. May not be reached. Since the elevator failure diagnosis device reads all the abnormal data including the abnormal data which is considered unnecessary for the actual failure diagnosis and displays it on the display device, it takes a lot of time to read the abnormal data. In some cases, a failure diagnosis result of the elevator cannot be obtained quickly.
Further, in an apparatus in which abnormal data is erased by reading the abnormal data, the abnormal data that does not need to be read, such as a repetitive abnormality in which the details of the abnormality are known in advance, may be used. Since the data is not erased unless the data is read out, much time is required to erase such unnecessary abnormal data.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems in the prior art and to provide a remote abnormality diagnosis apparatus for an elevator capable of efficiently performing an abnormality diagnosis of the elevator in a short time.

[0006]

FIG. 8 is an explanatory diagram showing a format of transmission data of a read / erase request transmitted from the diagnostic device to the abnormal data collection device.

In FIG. 1, 1 is an elevator, 2 is an elevator control device for controlling the operation of the elevator 1,
Reference numeral 3 denotes an abnormal data collection device that constantly monitors the operation state of the elevator 1 based on a signal from the elevator control device 2 and collects abnormal data. A failure diagnostic device for diagnosing the presence and the content of the abnormal data; 5 an abnormal data storage unit for storing and accumulating abnormal data of the elevator 1; 6 a heading for storing header information of the abnormal data stored in the abnormal data storage unit 5; An information storage unit, 7 is a collection control unit that controls each unit of the abnormal data collection device 3, and 8 is a communication unit that transmits the abnormal data transferred from the collection control unit 7 to the failure diagnosis device 4 via the communication line L. .

On the failure diagnosis device 4 side, 9 is a diagnosis control unit for controlling each unit of the failure diagnosis device 4, 10 is an input unit for inputting commands and input data, and 11 is a diagnosis control unit 9.
And a communication unit 12 for communicating with the abnormal data collecting device 3 via the communication line L. The diagnosis control unit 9 includes a memory (not shown) for storing the abnormal data received from the abnormal data collecting device 3.

The collection control unit 7 creates a heading list for organizing the heading information read out from the heading information storage unit 6 and displaying the heading information on the display unit 11. The heading list is as shown in FIG. An abnormality control flag FL field, which is a code indicating whether there is no abnormal data or one or more abnormal data, a collection number cn display field, which indicates the number of collections for each type of abnormality, Abnormality flag fl indicating presence / absence of data abnormality
It is composed of a display column and an abnormality content information ab display column indicating the abnormality content of data for each type of abnormality. The type of abnormality indicates a classification according to the class, type, installation location, and the like according to the degree of abnormality. In the heading list shown in FIG. 2, three types of abnormal data of A, B, and C are displayed as the types of abnormalities. The abnormal content information ab is composed of the abnormal content code of the abnormal data, the collection date and time, the start address and the size. However, the fixed-length abnormal data does not have the information of the start address and the size.

Next, a method of creating the above-mentioned heading list created by the abnormal data collection device 3 will be described. The collection control unit 7 constantly monitors the operation data received from the elevator control device 2 and transmits the operation data within a certain time to R.
Store in AM. When the collection control unit 7 determines that the operation data is abnormal, the operation data before and after the time is stored in the abnormal data storage unit 5. At this time, since the data amount of the operation data may be enormous, the operation data is compressed and then stored in the abnormal data storage unit 5.
When collecting one piece of abnormal data, the collection control unit 7 assigns an abnormal content code, which is a symbol corresponding to the content of the abnormality in the operation data, to the content code column of the abnormal content information ab display column, Similarly, the date and time of occurrence of the abnormality are allocated to the collection date and time column, the start address of the area where the abnormal data is stored is allocated to the start address column, the data amount of the abnormal data is allocated to the size column, and the display contents of the abnormal flag fl display column are displayed. To indicate that abnormal data is present, the number in the collection number cn display column of the type is incremented by one, and if it is the first abnormal data collection, the abnormal control flag FL indicates that abnormal data is present. Switch to

In the example shown in FIG. 2, the abnormal data of type A is composed of fixed-length operation data, and the abnormal data of types B and C are composed of operation data of arbitrary length. Has no head address column and no size column. Since abnormal data is sequentially stored in a predetermined storage area of the abnormal data storage unit 5 from an upper address each time it occurs, the abnormal data can be specified only by the storage order.

As shown in FIG. 3, the format of the transmission data of the abnormal data collection number is arranged in the order of the collection number A, the collection number B, and the collection number C for each type of abnormal data. As shown in FIG. 4, the format of the transmission data of the fixed-length abnormal data heading, that is, the type A abnormal data heading is such that the abnormal content code Ai and the abnormal content information ab of the collection date Ai are arranged in the order of occurrence of the abnormal data. I have. The format of the transmission data of the abnormal data header of an arbitrary length is, for example, in the case of the abnormal data header of type B, as shown in FIG. 5, the abnormal content code Bi, the collection date Bi, and the abnormal content information ab of the block No. Bj are included. They are arranged in the order of occurrence of abnormal data.

The amount of abnormal data is determined by a single communication performed between the abnormal data collection device 3 and the failure diagnosis device 4,
If the data exceeds the maximum transmission data amount unit that can send and receive data without losing reliability, it is not possible to send all the data in one transmission. There must be. Therefore, the number of divided readings calculated as an integer value obtained by dividing the abnormal data size by the maximum transmission data amount unit is defined as a block No.

As shown in FIG. 6, the format of the request transmission data that the failure diagnosis device 4 requests the abnormal data collection device 3 to read or delete the data is a hexadecimal H'80 representing a read as a processing code, an abnormal data H'0B for abnormal data of type B, for example, and B3 for abnormal flag abnormal data for example,
H'03, the block No. is arranged in the order of H'01 for the first reading. If the maximum block No. of the abnormal data of the abnormal flag B3 is 2, request transmission data in which the block No. is replaced with H'02 is subsequently transmitted.

Next, the operation of the data transmission / erasing process performed by the abnormal data collection device 3 in accordance with a request from the failure diagnosis device 4 will be described. FIG. 7 is a flowchart of the data transmission / erasing process. First, the collection control unit 7 waits until there is a line connection from the failure diagnosis device 4 (S1), and when a line connection is detected, receives the request data transmitted from the failure diagnosis device 4 (S2), It is determined whether or not the request content is a request for the collection number cn data of abnormal data (S3). If the determination result is correct, the collected number cn data in the heading information is read out from the heading information storage unit 6 (S4), transmission data in the format shown in FIG. (S5). Then, it is determined whether or not the failure diagnosis device 4 has completed the data transfer and disconnected the communication line L (S6). If the result of the determination is negative, that is, if the communication line L has not been disconnected, the procedure returns to step S2 to receive the next request data.

If the result of the determination in step S3 is negative, that is, if the requested content is not a request for abnormal data collection number cn data, it is determined whether the requested content is a request for elevator operation state information data (S7). ). If the determination result is correct, a predetermined operation control data group is read from the elevator control device 2 (S8), and transmitted to the failure diagnosis device 4 as operation state information data, and then the process proceeds to step S6 (S8).
9). If the result of the determination in step S7 is negative, that is, if the request is not a request for the elevator operation state information data, it is determined whether the request is a request for heading data (S10). If the judgment result is correct, the index information corresponding to the collection number cn is read from the index information storage unit 6 for each type of abnormal data (S11), and if the abnormal data has a fixed length, the format shown in FIG. The transmission data in the format shown in FIG. 5 is generated if the transmission data is of an arbitrary length, and the communication unit 8 generates the transmission data through the communication line L.
After that, the process proceeds to step S6 (S12).

If the result of the determination in step S10 is negative, that is, if the requested content is not a request for header data, it is determined whether the requested content is a request for abnormal data (S13). If the determination result is correct, the index information corresponding to the number of collections cn of the specified abnormal data is read from the index information storage unit 6 (S14), and the start address of the area where the abnormal data is stored and the size of the abnormal data are read. Is determined (S15), the abnormal data is read from the abnormal data storage unit 5 in accordance with the determined abnormal data heading information (S16), transmission data is created, and the communication unit 8 generates the transmission data via the communication line L. Is transmitted (S17), the abnormal flag fl of the abnormal data is canceled (S18), and the process proceeds to step S6.

If the result of the determination in step S13 is negative, that is, if the request is not a request for abnormal data, it is determined whether the request is a request for erasure of abnormal data (S19). If the determination result is correct, the process proceeds to step S18, in which the abnormality flag fl of the abnormal data is cancelled. If the determination result in step S19 is negative, it is determined that an abnormal request with undefined processing content has been received. After creating a response signal indicating the reception of the abnormality request and transmitting the signal to the failure diagnosis device 4, the process proceeds to step S6 (S20). If the result of the determination in the step S6 is true, that is, if the failure diagnosis device 4 completes the transmission and reception of data and disconnects the communication line L, the abnormality flag fl is compared with the collected number cn data and the abnormality flag fl is canceled. It is determined whether there is data (S21).

If the judgment result is correct, the abnormal data and the heading information are deleted or rearranged based on the heading list created based on the heading information read from the heading information storage unit 6 (S22). The operation of the abnormal data transmission / erasing process ends. If the result of the determination in step S21 is negative, the operation of the above processing is terminated. After the communication with the failure diagnosis device 4 is completed, the collection control unit 7 cancels the abnormality control flag FL so that there is no collected abnormal data, whereby the abnormal data stored in the abnormal data storage unit 5 is deleted. And all the heading information stored in the heading information storage unit 6 is erased, that is, the entire erasing process is performed.

Next, the operation of the abnormal data selective reading / erasing process for selectively reading and erasing abnormal data from the abnormal data collecting device 3 performed by the failure diagnosis device 4 will be described.
FIG. 8 is a flowchart of the abnormal data selective reading / erasing process.
First, it is determined whether a line connection request with the abnormal data collection device 3 has been detected (S51). If the judgment result is correct, a request is made for the number cn data of collected abnormal data (S
52), when the reception of the number of collected abnormal data cn data from the abnormal data collecting device 3 is completed (S53), the data is classified and collected according to the importance of the abnormality of the elevator.
The number cn of collected elevator abnormal data for each type is displayed on the screen of the display unit 11 (S54). Then, it is determined whether or not a command for terminating the operation of reading the elevator abnormal data and various information from the abnormal data collection device 3 is input to the input unit 10 of the failure diagnosis device 4 (S55).

If the result of the determination is negative, it is determined whether or not a command for reading abnormal data has been input to the input unit 10 (S56). If the result of the determination is negative, it is determined whether a command for erasing abnormal data is input to the input unit 10 (S
57). If the result of the determination is negative, that is, if a command for terminating the series of processing and reading or erasing abnormal data is not input from the input unit 10, a request to read the operation state information data of the elevator is made (S58). Then, when the operation status information data of the elevator is received from the abnormal data collection device 3 (S59), the diagnosis control unit 9 analyzes the operation status information data of the elevator, and visualizes the result in a predetermined display form. After displaying the number of collected abnormal data cn on the screen of the display unit 11 (S60), the process returns to step S55. If the result of the determination in step S55 is true, that is, if a command to end the operation of reading the elevator abnormal data and various information from the abnormal data collection device 3 is input to the input unit 10, the line with the abnormal data collection device 3 The connection is disconnected (S61), and the operation of the abnormal data selective reading / erasing process ends.

If the result of the determination in step S56 is true, that is, if a command for reading abnormal data is input to the input unit 10,
It is determined whether the command for reading the abnormal data is whether or not the selected abnormal data is to be read (all abnormal data is read) (S6).
2). If the determination result is negative, that is, if all the abnormal data is read, a command signal for reading all the abnormal data of the elevator from the abnormal data collection device 3 is created (S6).
3) A transmission request signal for all abnormal data is transmitted to the abnormal data collection device 3 via the communication line L (S64).

When all the abnormal data of the elevator is received from the abnormal data collecting device 3 (S65), the received abnormal data is stored in the memory (S66). Then, it is determined whether or not all the requested abnormal data has been received (S6).
7). If the result of the determination is no, that is, if all the requested abnormal data has not been received, the process returns to step S64, and the above-described processing up to step S67 is repeated. Eventually,
If the result of the determination in step S67 is true, that is, if all the requested abnormal data has been received, the line connection with the abnormal data collection device 3 is disconnected (S68), and all the received abnormal data is analyzed. The result is imaged in a predetermined display form and displayed on the screen of the display unit 11 (S70).
Then, a command to end the display on the display unit 11 is input to the input unit 1.
It is determined whether or not 0 has been input (S71). If the determination result is correct, the operation of the abnormal data selective reading / erasing process is terminated. If the determination result is negative, the process returns to step S70 and the display unit The display of 11 is continued.

If the result of the determination in step S62 is true, that is, if the selected abnormal data is read, a heading data request signal is transmitted to the abnormal data collection device 3 (S72). When the heading information data is received from the abnormal data collecting device 3 (S73), based on the heading information data, an abnormal information list table, which is a list of abnormal information including a set of abnormal contents and a collection date and time, is imaged. It is displayed on the screen (S74). Then, in step S75, the process waits for the operator to select the abnormal information to be analyzed. In step S76, it is determined whether the selection of the abnormal information is completed. When the selection of all the abnormality information to be analyzed by the operator is completed, it is determined whether the selection is a selection by reading (selection by erasure) (S77).

If the result of the determination is true, that is, if the selection is a selection by reading, the process proceeds to step S64, and the above-described step S7 is performed.
The same processing as that for reading all abnormal data up to 1 is performed. If the result of the determination in step S77 is negative, that is, if the selection is made by erasure, the erasure request signal for the selected abnormal data is transmitted to the abnormal data collection device 3 (S78). Step S79
Then, it is determined whether or not all the abnormal data requested to be deleted by the abnormal data collection device 3 has been deleted. And
When the erasure of all the abnormal data is completed, the line connection with the abnormal data collecting device 3 is disconnected (S80), and the operation of the abnormal data selective reading / erasing process is ended.

If the result of the determination in step S57 is true, that is, if a command to delete abnormal data is input to the input unit 10, whether the command to delete abnormal data is a command to delete all abnormal data (selection It is determined whether or not the erased abnormal data is deleted) (S81). If the result of the determination is correct, that is, if a command to delete all abnormal data is issued, the abnormal data collecting device 3
After sending a request signal for erasing all abnormal data (S8)
2), disconnect the line connection with the abnormal data collection device 3 (S
80), the operation of the abnormal data selective reading / erasing process ends. If the result of the determination in step S81 is negative, that is, if the selected abnormal data is to be erased, the process returns to step S72 to start the process of transmitting a header data request signal to the abnormal data collection device 3 and then to step S76. Heading data display
