First, the control program data in the microcomputer board 3 is copied in case the microcomputer board 3 for elevator control breaks down. The elevator maintenance person reads out the control program data in the microcomputer board 3 so as to read out the first external communication device 10 of the elevator maintenance device 8.
And the external communication device 6 of the microcomputer board 3 via the communication line f, and the command means 16 is connected to the second external communication device 11 of the elevator maintenance device 8. When a read command is given by the command means 16, the read command is processed by the central processing unit 9, and the microcomputer board 3 is connected to the first external communication device 10 via the communication line f 1 and the external communication device 6.
To the central processing unit 4. So the microcomputer board 3
The central processing unit 4 reads the control program data stored in the storage device 7 and sends the data to the elevator maintenance device 8 via the external communication device 6 and the communication line f1. The elevator maintenance device 8 sequentially sends the control program data sent from the microcomputer board 3 via the first external communication device 10 and the central processing unit 9 and writes the control program data in the storage device 12. At this time, processing is performed according to the flowchart shown in FIG. That is, in step S1, the central processing unit 9 determines whether or not there is write-inhibited data in the storage unit 12. If there is write-inhibited data, double writing is performed, so that write-inhibition is displayed in step S4, and the operation is terminated. On the other hand, if there is no write-inhibited data, the control program is written to the storage means 12 as shown in step S2, and after the writing to the storage means 12 is completed, the write-in of the prohibited data is made in step S3. Go and finish the work.

The storage in the storage device 12 is temporary, and the elevator maintenance staff returns the elevator maintenance device 8 to the dispatch base and transfers the data to another central device. As shown in the block diagram of FIG.
The second external communication device 11 in the elevator maintenance device 8 brought back to the dispatch base via the connection 2 is connected to a central device 14 such as a personal computer, and the central device 14 is used to write in the storage means 12 of the elevator maintenance device 8. The obtained control program data is stored in the storage means 15 of the central device 14. In this way, the elevator control program data in the microcomputer board 3 for elevator control is copied and stored. At this time, the processing is performed according to the flowchart shown in FIG. That is, in step S5, the central device 14 checks whether or not there is write-protected data in the storage unit 12. This confirmation is performed by either the central processing unit 9 of the elevator maintenance device 8 or the central device 14. If there is write-inhibited data, the control program data in the storage means 12 is transferred to the central device 1 as shown in step S6.
After the work is completed, the write-protected data in the storage means 12 is erased as shown in step S7, and then the operation shifts to work using another storage means. If there is no write-inhibited data, the end of writing to the storage device 15 is displayed on the central device 14 as in step S9, and the operator extracts the storage device and moves to another storage device. , End the work.

As described above, depending on the presence or absence of the write-inhibited data in the storage means 12, the storage device 15 of the central unit 14 is determined.
It is possible to immediately determine whether or not to store the data in the storage device. Even if the control program data is forgotten to be transferred from the storage means 12 to the storage device 15, since the write-inhibit data has been input into the storage means 12, it is discriminated when using this card, and the control program data is determined. You can input.

Next, remanufacturing when the microcomputer board 3 fails will be described. When the microcomputer board 3 of the control panel 2 installed in the elevator machine room fails, the microcomputer board 3 is stored in the storage means 16 of the central unit 15 in advance as described above without requesting the factory producing the microcomputer board 3 to remanufacture the board. Read out the elevator control program data and reproduce it again. That is, as shown in FIG. 2, the second external communication device 11 of the elevator maintenance device 8 is connected to the central device 15 via the communication line f1, and the first external communication device 10 of the elevator maintenance device 8 is A new microcomputer board 17 equivalent to the microcomputer board 3 is connected, and the central device 15 is operated to write the data in the storage device 16 to the new microcomputer board 17 via the elevator maintenance device 8 to thereby control the microcomputer for elevator control. The substrate can be remanufactured. In this way, it is possible to reduce the recovery time in the event of a failure of the microcomputer board as compared with the case where a new microcomputer board is ordered from a factory as in the conventional case.

In the above-described embodiment, the portable elevator maintenance device 8 configured as shown in FIG. 1 is used. However, the present invention is not limited to such a configuration.
2 is not limited to a memory card, and a storage means such as a floppy disk may be used.
