As described above, the first embodiment of the present invention shown in FIG.
According to the embodiment, a writing circuit such as an EEPROM,
The battery backup function of the RAM may be provided only in the elevator control device 2, and the hall terminals 1-1 to 1-1 may be provided.
The circuit configuration of n can be simplified. Further, according to the embodiment shown in FIG. 1, since the floor position is not set based on the position of the elevator, as in the case where a plurality of elevators are installed and the number of service floors is different,
Even if the service floor of the elevator is different from the floor name of the building, an accurate address can be set.

Next, with reference to the flow shown in FIG. 2, the hall terminal 1-1 according to the first embodiment of the present invention described above.
The operation at the time of setting addresses 1 to n will be described.

(1) First, the elevator control device 2
An address setting mode signal for changing to the address setting mode in the broadcast mode is transmitted to all hall terminals, and each of the hall terminals 1-1 to 1-n receives this signal and enters the address setting mode (step 201,
202).

(2) Next, the hall terminals 1-1 to 1-n
When the worker pushes the hall call buttons 3-1 to 3-n sequentially from the top floor or the bottom floor, the corresponding hall terminal receives the signal (step 203).

(3) The hall terminals 1-1 to 1-n which have received the signal indicating that the hall call button has been pressed transmit an address unique to each terminal to the elevator control device 2 (step 204).

(4) As will be described later, the elevator control device 2 determines the number of the hall terminal that has transmitted the unique address from the start of the address setting, that is, the number of the hall call button pressed. The floor name address corresponding to the hall terminal is identified, and the address is transmitted using the unique addresses of the hall terminals 1-1 to 1-n. The corresponding hall terminal receives the floor name address (step 205).

(5) The hall terminal performs hall call buttons 3-1 to 3-n the number of times corresponding to the received floor name address.
The worker can confirm the floor name by flashing the response light of the above or displaying the floor name by the indicators 4-1 to 4-n of the car position display. For this confirmation, the worker confirms whether or not the floor name is correct by blinking the response light, displaying the floor name, etc., and determines, for example, a hall call button in advance depending on whether or not the floor name is correct. By pressing the number of times
This is done by inputting the confirmation result to the hall terminal (step 206).

(7) In step 206, for example, if the hall call button is pressed twice and the floor name is entered incorrectly, the hall terminal sends an invalid signal to the elevator control device, and The processing is performed again (step 208).

In the above description, the elevator controller uses the broadcast mode to set the hall terminals on each floor to the address setting mode. However, the method for setting the hall terminals on each floor to the address setting mode is as follows.
It is also possible to use switches and other means. Further, the confirmation operation in step 206 can be omitted.

Next, the operation of the elevator control device 2 according to the first embodiment of the present invention at the time of setting an address will be described with reference to the flow chart shown in FIG.

(1) First, the elevator control device 2
An address setting mode is set by a signal from an external switch, a maintenance device or the like (step 301).

(2) Next, a mode change signal (address setting mode signal) for changing to the address setting mode using the broadcast mode received by all hall terminals.
Is transmitted (step 302).

(3) After the processing of step 302, the worker calls the hall call buttons 3-1 to 3-1 in order from the top floor or the bottom floor.
Since the hall terminals 1-1 to 1-n which have received the signal of pressing the hall call button and transmitted the address unique to each terminal to the elevator control device 2, the elevator control device Receives the terminal-specific address information (step 303).

(4) The elevator control device 2 responds to the hall terminal that has transmitted the unique address depending on the number of the hall terminal from the start of address setting, that is, the number of the hall call button pressed. The floor name address is identified, the floor name address and the unique address of the terminal corresponding to the address are written in the association table 24, and identified using the unique addresses of the hall terminals 1-1 to 1-n. The floor name address is transmitted to the hall terminal (steps 304 and 305).

(5) The next signal is received, and it is determined whether or not the received signal is an invalid signal from the hall terminal (steps 306 and 307).

(6) If it is determined in step 307 that the received signal is an invalid signal from the hall terminal, the portion of the association table written in step 304 is deleted, and the process returns to step 303. The unique address of the terminal transmitted from the hall terminal is received again (step 308).

(7) If it is determined in step 307 that the received signal is not an invalid signal from the hall terminal, the column of the related table 24 is advanced to determine whether or not the processing for all floors has been completed. If the processing for all floors has been completed, the address setting processing is completed (step 30).
9-311).

(8) If it is determined in step 310 that the address setting for all floors has not been completed, step 30
3, the process from the step of receiving the unique address from the next hall terminal is repeated.

By the processing of step 304 described above, the relation table 24 between the hall terminal specific address and the floor name address based on the service floor numerical value of the building or elevator bank as shown in FIG. 4 is created.

The above-described first embodiment of the present invention has been described by taking as an example the setting of a floor name address for a hall terminal when an elevator device is newly installed. In general, the power supply of the hall terminal of the elevator device and the elevator control device is not turned off after the operation of the elevator device is started, but the R in the hall terminal is broken due to a failure such as a power failure.
If the floor name address stored in the AM 15 is lost, the EEP in the elevator control device 2 is restored when the power is restored.
ROM or battery-backed RA
By transmitting necessary information from the association table 24 in the M23 to the hall terminal, the floor name address in the hall terminal can be recovered.

FIG. 5 is a flowchart for explaining an operation of setting an address when one floor name address of a hall terminal is not set as a second embodiment of the present invention.
Hereinafter, this will be described. Here, the overall operation including the elevator control device 2 and the hall terminals 1-1 to 1-n will be described.

In this embodiment, when one of the hall terminals is replaced or added due to a failure or addition of hall equipment, a change in hall equipment, etc., all floors are processed by the processing as described above. Resetting the address of the hall terminal requires a lot of time and effort, and is intended to solve such a problem.

An inquiry is made as to whether a floor name address has been set for each hall terminal using the broadcast mode (step 501).

(2) The hall terminals 1-1 to 1-n in which the floor names are not set receive the R, and
It confirms that its own floor name address is not set in the AM 15, and transmits the terminal-specific address to the elevator control device 2 (step 502).

(3) Next, the elevator control device 2
Based on the floor name address stored in the association table 24, transmission / reception is performed with each hall terminal to find a floor name address with no response (step 503).

(4) The floor name address that has not been answered in step 503 is the floor address of the unique address of the hall terminals 1-1 to 1-n to which the previously transmitted floor name is not set. The corresponding floor address is sent to the hall terminal 1-1 to 1-n by using the unique address of the unset terminal which has been received as a name address in the association table 24 (step 504). , 50
5).

(5) The hall terminals 1-1 to 1-n which have transmitted the terminal-specific addresses to the elevator control device 2 receive the floor name addresses sent as their own floor name addresses, and receive the received floor names. The response lights attached to the hall call buttons 3-1 to 3-n are blinked according to the floor name address, or the floor names are displayed by the indicator 4-1 to 4-n of the car position display. Ask the dispatched worker to confirm whether the number of floors is correct. This confirmation
This is performed in the same manner as step 206 described with reference to FIG. 2 (steps 506 and 507).

(6) It is confirmed whether or not the number of floors is correct by an input by a worker using the hall call button or the like. If the number of floors is correct, the process is terminated.
And the process is repeated (step 508).

In the above description, the unique address of the hall terminal added later due to a failure or the like is set so that the most significant bit is different from the unique address used at the time of new delivery. Can be prevented from being duplicated. Also in this case, step 50
The confirmation operation after 7 may be omitted.
