BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a state in the middle of repair work in an elevator to which an elevator repair method according to an embodiment is applied. The same parts as those in FIGS. 5 and 6 are designated by the same reference numerals, and detailed description of the overlapping parts will be omitted.

During the repair work, the hoisting machine 3 of the car 5, a new control panel 12, and the new control panel 12 are installed in the machine room 2 above the hoistway 1 in which the car 5 is moved up and down. A new call registration processing module 17 including a computer incorporated in the control panel 12 and a temporary call registration processing module 18 including a computer are provided.

A new serial signal line 15 is connected to the input / output port 19 of the new call registration processing module 17. On the other hand, each input / output terminal 23 of the temporary call registration processing module 18 is connected to the parallel signal line 11 before replacement.

The call registrars on each floor from the first floor to the twenty-fourth floor are in the process of being replaced. For example, the call registrars on the first floor, the twenty-third floor, and the twenty-fourth floor are the call registrars 7 before replacement.
The call register on each of the first and the second floors is a new call register 14 after replacement. Each call register 7 on the first floor, the 23rd floor, and the 24th floor before replacement is connected to a temporary call registration processing module 18 via a parallel signal line 11. This signal system is called "old system". On the other hand, each new call register 14 after replacement on the second floor and the 22nd floor is connected to a new call registration processing module 17 via a serial signal line 15. This signal system is called "new system".

The temporary call registration processing module 18 designates a digital floor at which a computer can understand the call signal from each call register 7 before replacement, which is input to each input / output terminal 23 via the parallel signal line 11. The converted call information is sent to the new call registration processing module 17.

A car call table 20 is provided in the new call registration processing module 17. Further, in the car call table 20, as shown in FIG. 2, a new car call table 21 and an old car call table 22 are formed. In each car call table 21 and 22,
For each floor from the 1st floor to the 24th floor, the presence / absence status of "call" registration is valid or invalid for the relevant floor, and the "call" flag is provided for the relevant floor Has been. Naturally, the "call" flag can be set only on the floors in which the presence / absence status is set to valid. further,
For each of the car call tables 21 and 22 for the same floor, the presence / absence status opposite to each other is set.

In the new car call table 21, each new call register 1 is added via a new system (serial signal line 15).
The "call" designating the floor received from 4 is registered. On the other hand, in the old car call table 22, a "call" designating the floor received from each call register 7 before replacement is registered via the old system (parallel signal line 14).

Before the call register 7 of each floor 1-24 is replaced with the new call register 14, the presence / absence status of each floor 1-24 of the old car call table 22 is set to be valid. 1 to 1 of the new car call table 21
The presence / absence status of each of the 24 floors is set to be invalid. Then, every time the worker replaces the call registration device 7 of one floor with a new call registration device 14, the presence / absence status of the relevant floor of the old car call table 22 is set to invalid, and the new car call table 21 is set. Set the presence / absence status of the relevant floor to valid.

Therefore, at the stage when the call register 7 of all floors 1 to 24 has been replaced with the new call register 14, the presence / absence status of each floor 1 to 24 of the old car call table 22 is invalid. And the presence / absence status of each floor 1 to 24 of the new car call table 21 is set to valid.

The new call registration processing module 17 incorporated in the new control panel 12 is either the new system (serial signal line 15) or the old system (parallel signal line 11) via the temporary registration processing module 18. When a "call" designating a floor is input from the new call registration device 14 or the call registration device 7 before replacement via the pressing operation of the call button 8 on each floor, according to the flow chart of FIG. The registration process for the car call table 20 of the corresponding "call" and the transfer process for the control unit 12 of the corresponding "call" are executed.

First, it is judged whether the "call" designating the floor caused by the operation of pressing the call button 8 is the "call" input from either the old or new system (Q1). The setting status of the presence / absence status of the designated floor of the old car call table 22 of the call table 20 is checked (Q2). When the presence / absence status is set to be valid, it is determined that the "call" with the floor specified this time can be registered (Q3), and the call flag of the specified floor of the old car call table 22 is determined. Is set to "1" (Q4).
At the same time, the registered “call” information specifying the floor is sent to the control unit 12. The control unit 12 drives and controls the hoisting machine 3 so that the car 5 moves to the floor designated by the "call". The hoisting machine 3 moves the car 5 to the designated floor. When the car 5 arrives at the relevant floor, the call flag of the relevant floor of the old car call table 22 is cleared to "0".

When the presence / absence status is set to invalid in Q2, it is determined that the "call" designating the floor input this time cannot be registered, and the "call" this time is registered.
The process for is ended (Q6).

When a "call" designating a floor caused by the push-down operation of the call button 8 is input from the new system at Q1, the designated floor of the new car call table 21 of the car call table 20 is input. Check the setting status of the presence / absence status of (Q7). When the presence / absence status is set to be valid, it is determined that the "call" with the floor specified this time can be registered (Q8), and the call flag of the specified floor of the new car call table 21 is determined. Is set to "1" (Q4). At the same time, the registered “call” information specifying the floor is sent to the control unit 12. The control unit 12 calls “call”.
The hoisting machine 3 is driven and controlled so that the car 5 moves to the floor designated by. The hoisting machine 3 moves the car 5 to the designated floor. When the car 5 arrives at the relevant floor, the call flag of the relevant floor of the new car call table 21 is cleared to "0".

When the presence / absence status is set to invalid in Q7, it is determined that the "call" specifying the floor input this time cannot be registered, and the "call" this time is determined.
The processing for (1) is completed (Q9).

In this way, the new call registration processing module 17 incorporated in the new control panel 12 sends the "call" designating the floor input from the old and new call registrars 7 and 14 of each floor to the old and new car. The floors designated as valid in the corresponding tables 21 and 22 of the call tables 21 and 22 are set, and therefore even in the state in which the new call register 14 and the call register 14 before replacement are mixed. , The elevator can be operated normally.

FIG. 4 is a flow chart showing the procedure for the elevator renovation work. First, the existing parallel signal line 11 is disconnected from the existing call registration processing module 10 shown in FIG. 6A (S1). Next, the control panel 9 with the call registration processing module 10 installed is replaced with the control panel 12 with the new call registration processing module 17 installed (S2).

Then, the temporary call registration processing module 18 is attached (S3). Then, the parallel signal line 11 which has been separated previously is connected to each signal terminal 23 of the temporary call registration processing module 18 (S4). New serial signal line 1
5 is laid from the machine room 2 to the hall of each floor, and the upper end of the serial signal line 15 is connected to the input / output port 19 of the new call registration processing module 17 (S5).

The car call table 20 of the new call registration processing module 17 is initialized. Specifically, as described above, the presence / absence status of each floor 1-24 of the old car call table 22 is set to be valid, and the presence / absence status of each floor 1-24 of the new car call table 21 is invalid. (S6). When the above work is completed, the elevator can be operated, so the elevator is once operated (S7).

Next, the worker stops the operation of the elevator and sets the call register 7 on one floor to the new call register 1
7 (S8). The new call registration device 17 is connected to the serial signal line 15 laid previously (S9). Next, the setting status of the presence / absence status of the car call table 20 of the new call registration processing module 17 is updated. Specifically, as described above, the presence / absence status of the relevant floor of the old car call table 22 is set to be invalid, and the presence / absence status of the relevant floor of the new car call table 21 is set to be valid (S10). . When the work of replacing the call register 7 with the new call register 17 for one floor is completed,
Since it is possible to operate the elevator, the elevator is once operated (S11).

If the work of replacing the call register 7 with the new call register 17 on all floors has not been completed (S12), the process returns to S8, the operation of the elevator is stopped, and the floors that have not been replaced are replaced. The work of replacing the call registration device 7 with a new call registration device 17 is started.

When the work of replacing the call register 7 with the new call register 17 on all floors is completed (S12), the parallel signal line 11 is removed (S13), and finally the temporary call registration processing module 18 is installed. Remove (S14).

In the elevator repairing method thus constructed, in addition to the new call registration processing module 17, the "call" from each call register 7 before replacement on each floor is transferred via the parallel signal line 11. A temporary call registration processing module 18 that takes in and transfers the new call registration processing module 17 is provided.

Therefore, even when the new call register 14 and the call register 7 before replacement are mixed, the elevator can be operated normally, so that the call register 7 on each floor can be operated.
Since the elevator can be operated each time in the stage of sequentially exchanging (replacement) the new call register 14 with each other, the call register of each floor must be exchanged for each floor outside the working hours of the user. As a result, it is possible to proceed with the elevator renovation work while minimizing the impact on the users.

The present invention is not limited to the above embodiment.

The new call registration unit 14 on each floor sets the floor of the current position of the car 5 to the new call registration processing module 1
It is possible to display the floor of the current position of the car 5 by a number by receiving it from 7 through the serial signal line 15.
Thus, by changing the display system from the conventional dot system to the digital number display system, it becomes very easy for the elevator user to understand.

Furthermore, in the process of replacing the call register 7 on each floor with the new call register 14, the call register 7 before being temporarily replaced on the same floor can be immediately removed. It is also possible to install 14 additionally.

In this case, the call register 7 before replacement transmits the "call" generated via the parallel signal line 11 to the temporary call registration processing module 18, and the new call register 14
Transmits the "call" generated via the serial signal line 15 to the new call registration processing module 17.

As described above, the call register 7 before replacement and the new call register 14 can be temporarily used on the same floor, and the construction worker selectively selects one of them during the repair work. By setting the usage state, it is possible to arbitrarily set the work process of the repair work or the additional construction work.

[0051]

As described above, in the elevator repairing method of the present invention, in addition to the new call registration processing module, the call from each call register before replacement on each floor is taken in, A provisional call registration processing module for transferring to a new call registration processing module is provided.

Therefore, during the repair work, it is possible to operate the elevator using the old and new call registration devices on each floor, the repair work can be further subdivided, and the effect of expanding the variation of the construction plan can be obtained. It is also possible to change the display format of the current car position on the call register on each floor.
