Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS. FIG. 6 is a flowchart illustrating a schematic operation of the elevator control device 2A,
The operation of the elevator control device 2A is as follows.
1 controls the operation of the elevator according to the control program stored in the ROM 22 and temporarily records the operation control data and the operation status data in the RAM (1) 25 together with the elevator movement of the car, the opening and closing operation of the car door (step S).
61). At this time, the operation control data and the operation status data are recorded in the RAM (1) 25 as “failure status data” necessary for the fault diagnosis, regardless of whether or not a fault has occurred (step S62).

During the operation control of the elevator, the CPU 21 detects any elevator failure (step S6).
3) The failure status data is read out from the RAM (1) 25, and the failure status data is put on a telephone line through the communication device interface (I / F) 27 with an automatic telephone function and sent to the computer device 5A of the maintenance company monitoring center ( Step S64), the sent failure status data is used as the latest data at the time of failure occurrence,
Will be notified.

As described above, after reporting the failure status data or when recording the failure status data in step S62, the CP
U21 is a communication device interface (I
/ F) 27 to determine whether or not there has been any communication request from the monitoring center (step S65). At this time,
If it is determined that there is a communication request, communication processing 1 is performed (step S66). Details of the operation are shown in the flowchart of FIG.

In the communication processing 1, first, the failure diagnosis result of the elevator for which the communication request is made in the computer device 5A is a character data recording request such as "The failure cause is estimated to be an OFF failure of the XX circuit." (Step S66A), the failure diagnosis result is recorded in one memory area of the RAM (2) 26 (Step S66B).

Alternatively, it is determined that the communication request is a request to record a status confirmation message using character data such as "Cannot be estimated. Please answer the voltage of xx circuit" (step S66C) . The CPU 21 is a maintenance device 1A
A status confirmation message is recorded in the RAM (2) 26 (step S66D). Each of the character data is code information that can be translated by the maintenance device.

Further, if it is determined that the communication request is a request for inputting failure status data (step S66E), the CP
U21 stores the latest failure status data at the time of the current communication request in RAM
(1) Read from 25 and send it to the computer 5A (step S66F).

Next, when it is determined that the communication request is a communication request from the maintenance device 1A (step S6).
7), the CPU 21 determines whether or not a failure has been determined (step S67A). If no failure has been determined, the CPU 21 executes the communication process 2 in step S68 (see FIG. 8).
First, when it is determined that the communication request from the maintenance device 1A is a car call registration request (step S6).
8A), the CPU 21 registers the requested car call, and communicates the current car call registration status to the maintenance device 1A through the maintenance device interface (I / F) 23 (step S68B).

Alternatively, if it is determined that the communication request is a request to read operation status data (step S68C), the CP
U21 is the number of times the elevator has been activated from the RAM (1) 25,
The operation status data such as the running time is read and communicated to the maintenance device (step S68A). Next, when it is determined that the communication request is a request for reading the failure status data (step S66E), the CPU 21 sets the RAM (1) 25
The failure status data is read out from the maintenance device 1A.
(Step S68F).

Note that in step S67A, the CP
If U21 determines that a failure has occurred, the communication process 3 (FIG. 9)
(See step S69). First, when it is determined that the communication request from the maintenance device 1A is a request for reading a failure diagnosis result by the computer device 5A (step S69A), the CPU 21 stores the communication request in the RAM (2) 26 in step 66B of the communication process 1 above. The recorded failure diagnosis result is read out, and the maintenance device 1A is read out.
(Step S69B).

Alternatively, if the computer device 5A determines that it is a request to read out a status confirmation message issued from the computer device 5A as a result of performing one type of failure diagnosis (step S69C), the CPU 21 proceeds to the RAM. (2) Read the status confirmation message recorded in 26 and communicate with the maintenance device 1A.

If it is determined that the communication request from the maintenance device 1A is a request to record a correct / wrong answer to the diagnosis result read in step S69B (step S69E), the CPU 21 receives the input from the maintenance device 1A. If the failure diagnosis result is incorrect along with the correct / wrong answer information of the failure diagnosis result, a re-diagnosis request command for the computer device 5A is recorded in the RAM (2) 26 (step S69E). The correct / incorrect answer information is sent to the computer 5 of the maintenance company monitoring center via the telephone line by the communication device interface (I / F) 2B with the automatic telephone function.
A is notified (step S69I).

[0038] Alternatively, the communication request, step S69 D
If it is determined that the request is a response recording request for the status confirmation message read in (step S69G), the CPU
21 records the response information of the status confirmation message input from the maintenance device 1A in the RAM (2) 26. The correct / incorrect answer information is reported to the computer device 5A of the maintenance company monitoring center via the telephone line by the communication device interface (I / F) 2B with the automatic telephone function (step S69I). The CPU 21 repeatedly executes each of the above processes when controlling the operation of the elevator.

Next, the operation of the computer 5A of the maintenance company monitoring center will be described with reference to the flowchart of FIG. First, the CPU 5 of the computer device 5A
1 automatically reports the failure status data recorded in the RAM (1) 25 from the elevator control device 2A via a telephone line when a failure occurs in the elevator device (step S1).
01). Next, the CPU 51 sets the failure diagnosis database 57
Then, the received failure status data is multiplied by the failure analysis program stored in the storage device to perform a failure diagnosis (step S102).

As a result of this failure diagnosis, if the CPU 51 cannot identify the cause of the failure, the CPU 51 sends a status confirmation message requesting status confirmation data to identify the cause of the failure to the display device 54 or the input / output device (such as a printer). ) (Step S104). This status confirmation message is sent to the elevator control device 2A as described in steps S66C and S66D of the communication process 1 (FIG. 7), and is sent to the RAM.
(2) Recorded in 26 (step S105). next,
If a response to the status confirmation message is obtained from the elevator control device 2A (step S106), the process returns to step S102, and the cause of the failure is specified using the response to the status confirmation message. Hereinafter, the processing of steps S102 to S106 is repeated until the cause of the failure is specified.

Alternatively, in step S103, the CP
When U51 identifies the cause of the failure, it outputs the failure diagnosis result to the display device 54 or the input / output device (such as a printer) 56 (step S107), and outputs the failure diagnosis result to the elevator control device 2A via the telephone line. Send to RAM
(2) Record in 26 (step S108). The determination result of the failure diagnosis result is sent to the maintenance device 1A by the RAM (2) 2 of the elevator control device 2A as a correct or incorrect answer.
6 and sent to the computer 5A (steps S108, S109).

When the computer device 5A obtains the correct answer, it checks the answer, and when it is determined that the failure result is correct, updates the diagnosis database 57 and records data on the identified failure cause (steps S110, S1).
12). However, if the failure diagnosis result is determined to be incorrect based on the correct answer content (step S110), the latest failure status data is fetched from the elevator control device 2A (step S111). Thereafter, the CPU 51 returns to step S102, and takes the latest failure status data into the failure analysis program of the diagnosis database 57 and performs a failure diagnosis for identifying the cause of the failure.

Further, based on the failure cause identification result, steps S104 to S106, S102 and S103 are performed as described above.
Loop or steps S107-S112, S10
2. Loop of S103 is repeated.
