Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an apparatus for remanufacturing a microcomputer board for elevator control according to an embodiment of the present invention, in which control program data is read from a microcomputer board provided on an elevator control panel. The control panel 2 installed in the elevator machine room of the customer building 1 has a microcomputer board 3 for giving an operation instruction to the elevator, the elevator control device 5, a storage device 7 storing elevator control program data, and external communication. The devices 6 are each connected to the central processing unit 4. Elevator maintenance device 8 portable by elevator maintenance staff
A first external communication device 10 on the elevator control device 5 side connected to the central processing unit 9, a second external communication device 11, a storage device 12 such as a memory card having a memory card connection device 12a, It comprises a data error detection device 13 for detecting data errors and a command device 14 such as a simple console connectable to the second external communication device 11. This data error detection device 13 is, for example,
The data passing through the elevator maintenance device 8 are sequentially added, and after the reading is completed, the result is stored in the storage device 12 or the like.

First, the elevator control program data in the microcomputer board 3 is copied in case the microcomputer board 3 for elevator control fails. The elevator maintenance worker connects the first external communication device 10 of the elevator maintenance device 8 and the external communication device 6 of the microcomputer substrate 3 via the communication line f in order to read the elevator control program data in the microcomputer board 3. At the same time, the command device 14 is connected to the second external communication device 11 of the elevator maintenance device 8. When a read command is given by the command device 14, the read command is processed by the central processing unit 9 and transmitted to the central processing unit 4 of the microcomputer board 3 via the first external communication device 10 and the communication line f and the external communication device 6. .
The central processing unit 4 of microcontrollers substrate 3 reads the elevator control program data stored in the storage device 7, sends the data through the external communication device 6 and the communication line f to the elevator maintenance device 8. The elevator maintenance device 8 sequentially sends the elevator 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 data in the storage device 12. At this time, for example, the data error detection device 13 sequentially adds the data passing through the elevator maintenance device 8 and stores the result in the storage device 12 or the like after the reading is completed.

The storage in the storage device 12 is temporary, and the elevator maintenance staff takes the elevator maintenance device 8 back to the dispatch base and transfers the data to another central device. Thereafter, as shown in the block diagram of FIG. 2, the second external communication device 11 in the elevator maintenance device 8 brought back to the dispatch base via the communication line f1 is connected to the central device 15 such as a personal computer. the manipulate remembers
It is stored in the device 16. In this way, the elevator control program data in the microcomputer board 3 for elevator control is copied and stored. Also at this time, the data error detection device 13 sequentially adds, for example, the data passing through the elevator maintenance device 8, stores the result in the storage device 12 or the like after the reading is completed, and compares the result with the previous result. Then, it can be understood that the data has been correctly migrated, and if the data does not match, the data has been lost and changed for some reason.

Next, remanufacturing when the microcomputer board 3 fails will be described. If the microcomputer board 3 of the control panel 2 installed in the elevator machine room breaks down, it is stored in the storage device 16 of the central unit 15 in advance as described above without requesting the factory that manufactures 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 connect the microcontroller board 3 equivalent new microcontroller board 17 which, <br/> depending on writing data in the storage device 16 by operating the central unit 15 via the elevator maintenance unit 8 to a new microcontroller board 17 Thus, the elevator control microcomputer board 17 can be reproduced. At this time, as in the case described above, the data error detection device 13 sequentially adds, for example, the data passing through the elevator maintenance device 8 and stores the result in the storage device 12 or the like after the reading is completed. If they match, it can be understood that the data has been correctly transferred, and if they do not match, it can be understood that the data has been lost and changed for some reason. In this way,
Compared to a conventional case where a new microcomputer board is ordered from a factory, the recovery time in the event of a microcomputer board failure can be shortened, and highly reliable data can be transmitted and received by the data error detection device 13.

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.
