Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator signal transmission device, and particularly to an elevator control signal transmission device that transmits elevator control signals in a time-division manner.

[Prior Art] Fig. 5 is a block diagram showing a conventional elevator signal transmission device disclosed in, for example, Japanese Unexamined Patent Application Publication No. 2001-288586. The control device (1) includes a control microcomputer (2), a master station (3), an address setting command generator (19), and a console interface (2).
3) It is composed of

The mask station (3) is connected to remote stations (5a) to (5a) installed on each floor via a transmission line (4).
It sends and receives data to and from the control microcomputer (2
).

Further, the address setting command generation unit (19) receives an address setting command (2a) from the control microcomputer (2).
Alternatively, when a manual address setting command (2o) is input, an address transmission command (19a) for the mask station (3) is sent.

FIG. 6 is a block diagram showing an example of the internal configuration of the master station (3). In FIG. 6, the control signal storage unit (11) stores, for example, hall display data taken in from the control microcomputer (2), and the transmission mote determination command unit (7) stores information such as the state of the transmission system and It checks the presence or absence of an address setting mode command, and switches transmission between normal transmission mode and address transmission mode. When the normal transmission processing unit (8) is switched to normal transmission mode 1 by the transmission mode determination command unit (a), the control signal storage unit (11) stores the transmission data and status signals during normal transmission as a control signal. Transfer is made between the microcomputer (2) and the receiver via the section (11). In addition, when the address setting transmission section (12) is switched to the address transmission mode by the transmission mode determination command section (a), the address information storage section (12) is controlled by the microcomputer (2).
3), and transmits it to each remote station (5a) to (5d) via a signal transmission control unit 9) and an I/Lance transmitter receiver (10).

On the other hand, Fig. 7 shows the remote station (5) which is not shown in Fig. 5.
It is a block diagram which shows the example of an internal structure of a)-(5d).

In FIG. 7, the signal transmission control (9) takes in data received by the transmitter receiver (10) and sends it to the transmission address determination section (16). This transmission address determination unit (16) monitors the received data and the data in the address data storage unit (21) of its own station, and determines whether it has selected its own station, received a transmission mode command, has not set an address for its own station, etc. It is. The transmission mode determination section (17) determines a command to switch to address setting modes 1 through from the transmission data, and switches the transmission mode to address setting modes 1 through when it is determined that the address has not been set. Data transmission/reception processing unit (
14) transfers data between the data input/output processing section (15) and the master station (3) when a permission command is issued by the transmission mode determination section (17) and the mode is switched to normal transmission mode. be. In addition, when the transmission mode determination unit (17) issues a permission command to the address setting transmission processing unit (11) and switches to the address setting mode, a data input/output command is issued for the call signal by operating the elevator hall call switch (6). It receives the data through the station (15), determines it as an address setting request signal, and receives and inputs the data on the transmission path (4) as address information of its own station.

The input a)~response information is stored in the address data storage unit (21).
).

This storage section (21) uses a rewritable R leaf so that the information will not be erased even in the event of a power outage.

Next, to describe the operation of the apparatus configured as described in Section 1, a case will be described in which the elevator installation is completed and addresses are set for each remote station before normal operation begins. In FIG. 5, when the electric power control device (1) is turned on, each remote station (5a) to (5d) is activated by the transmission mode determination unit (
17), when it is determined that the address has not been set and a permission command is issued to the address setting transmission processing section (18), this address setting transmission processing section (18) immediately enters a state in which it has a setting request input. In this case, the ON signal of the hall call switch SW input to the spider-1 to station is used as the setting request input.

On the other hand, the control microcomputer (2) sends an address transmission command (19a) to the mask station (3) shown in FIG.
) is issued, the transmission mode judgment command section (7) issues a prohibition command to the normal transmission processing section (8) and an address setting transmission section (12).
) to issue a permission command and switch to address setting mode. At this point, the master station (3) is switched to the address setting mode and the address information storage section (1) is switched to the address setting mode.
3) to the control microcomputer (2).

The control microcomputer (2) uses the data input via the console interface (23) as address information to be set in the remote station and sends the data to the address setting transmission unit (12) via the address information storage unit (13).
).

The address setting transmission section (12) transmits the received data via the signal transmission section (9) and the I-transmission receiver (10).

After this, the mask station and mote station are ready for address setting. In this situation, one of the elevator installers in Fig. 5 inputs the address information assigned to the remote station (5a) on the bottom floor using the console, and then one of the other elevator installers or , and turn on the hall push button (6a) of Remote 1 to Station (5a).

The remote station's air address setting transmission processing section (18) takes in the address data received at that time as its own station address and transmits the address determination section (18).
6) to be stored in the address data storage unit (21).

Elevator control device (1) First enter the address information entered from the console and go to the master station (
3), the address information of the remote station (5a) continues to be sent from the master station (3), and the remote station (5a) can receive the correct address data.

As described above, the addresses of the remote stations on each floor are set while communicating with the two installers. Once the settings have been completed, the remote stations are the master station (3
) will be in a standby state until the normal transmission command is received.

Since the mask station (3) always transmits the address inputted on the console, that is, the address data of the remote station to be set, all the remote stations 1 to 1 can set their respective addresses correctly.

[Problems to be Solved by the Invention] Since the conventional elevator signal transmission device was configured as described above, it had the following problems.

■ The task of setting up an address input section in the elevator control section and pressing a button that does not set and memorize the address on the terminal is 1.
One worker sets the address in the elevator machine room, then gets down to the elevator and presses the button.However, one of the two workers sets the address in the machine room, and the other one presses the button at the landing, making it more efficient. isn't it.

■ When installing an elevator, there are many workers in the building, and there is no guarantee that the address setting worker will not press the button for the floor that has already been set. It turns out to be wrong.

This invention was made in order to solve the above-mentioned problems, and it is an elevator signal that allows one worker to set an address, thereby improving work efficiency and preventing erroneous address setting operations. The purpose is to obtain a transmission device.

[Means for Solving 1 Problem] An elevator signal transmission device according to the present invention connects an elevator control unit and a plurality of terminal devices via a serial transmission path, and transmits and receives data through the serial transmission path. In the elevator signal transmission device, when setting the transmission address of the terminal device, the elevator control section calculates address information from the stop position of the car, and this address information is transmitted from the elevator control section to the terminal device. It is designed to be stored in memory.

[Function] In this invention, the address setting mode is set using a switch on the elevator control unit or the car operating panel, etc., the same worker stops the elevator traveling to the floor for which the address is to be set, and the elevator control unit determines the set address from the stop floor data. was calculated and sent to each terminal device, and the worker stopped running [I
Press the hall call button on I to set. As a result, the address can be set while the car is running, allowing one person to work efficiently and preventing erroneous operations when setting the address.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure does not show one embodiment of the present invention but is a block diagram.
In the figure, parts corresponding to those in FIGS. 5 and 6 are designated by the same reference numerals, and detailed explanation thereof will be omitted. In this embodiment, a car position storage section (30) is provided between the control microcomputer (2) and the address setting transmission section (12).

This car position storage section (30) stores and sets address information corresponding to the position when the car is moved.

Next, the operation of one embodiment of the present invention will be explained. The present invention uses the car stop position as the source data of the address data instead of setting the address data on the console in the conventional example.

That is, the address is set using a dedicated switch (not shown) on the console or the car operation panel, and the operator gets on the car and uses the car operation panel to move the car to the desired floor. By doing this, the control microcomputer (2) moves the car to the 5th floor when setting the car position to a specific floor, for example, the 5th floor. At this time, the car position data of the control microcomputer (2) is 05.
The control microcomputer (2) sends this car position data to the car position storage section (30) and sets it.

Based on this car position data, the signal transmission control unit (9) then uses the 5F address 04'' (for example, 00''I
F, "01" = 2F, ...04 = 5F...
In other words, the car position -1 is calculated to be "04'" and is transmitted to the data transmission remote stations (5a) to (5d) as in the conventional example. The subsequent operation is similar to the conventional example.

In this way, by associating the car position with the address setting data, the two main tasks that were the drawbacks of the conventional example are eliminated, and one worker can set the address setting mode, move the car to the desired floor, and The setting is completed by getting off at the landing and pressing the hall call button.

However, even in this embodiment, if a third party other than the address setting mode operator accidentally presses the hall call button on another floor, the A/R settings for that floor may be the same as the floor for which the address setting mode is being set. There is sex. That is, if a third party accidentally presses the hall call button on the 3rd floor when attempting to set the 5th floor as in the above example, there is a possibility that the hall call button on the 3rd floor will also be set as the hall call button on the 5th floor.

Therefore, in order to prevent this erroneous operation, the following other embodiments can be considered. FIG. 2 shows another embodiment of the present invention. In FIG. 2, parts corresponding to those in FIG. 7 are denoted by the same reference numerals, and detailed explanation thereof will be omitted. In this embodiment, a gate circuit such as an AND circuit (31) and a setting jumper (32) are provided, one input end of the AND circuit (31) is connected to the transmission address determination section (16), and the other input end is connected to the transmission address determination section (16). Connected to the mode determination section (17) and connected to a positive power supply (not shown) via a setting jumper (32),
The output terminal of the AND circuit (31) is connected to the address data storage section.
21). Here, as an example, when the setting jumper (32) is connected, the remote station is in address setting mode 1~, and the setting jumper (32) is connected.
32) is not connected, it is assumed that the remote station is not in address setting mode 1.

Next, the operation of the other embodiment shown in FIG. 2 will be explained. Now, by inserting the setting jumper (32), the ant circuit (
31) is in the open state and the remote station is in the address setting mode from the transmission mote determination unit (17) → address setting transmission processing unit (1, 8)
- Transmit to the control microcomputer (2) through the screen signal transmission control section (9). As a result, the control microcomputer (2) recognizes that the jumper, that is, the remote station is set to the address setting mode, and switches to the address setting mode. Thereafter, the same operation as in the above embodiment is performed to set an address in the address data storage section (21). After completing the address setting, the operator removes this setting jumper (32) and switches to address setting mode 1.
to. At this time, when the setting jumper (32) is removed, the gates 1 to 1 of the AND circuit (31) are closed, and when the address setting mode is entered such as when setting another floor, even if the hall call button is pressed. A new address cannot be set in the address data (21) storage section. This eliminates the possibility of erroneous operation as described above.

In this way, in this example, the worker loads the remote station to be installed in a basket, gets off at the landing, connects the transmission line, etc., presses the hall call button, and removes the setting jumper, and the installation and settings are automatically performed. done to.

FIG. 3 is an example of a program flowchart showing the operation of the control microcomputer (2).

In step (41), it is determined whether the address mode is ON or not. If it is ON, the current position of the car is converted into corresponding address data in step (42), and in step (43)
and transfers the address data to the transmission section. Then, in step (44), it is determined whether or not the address set command is ON, and if it is ON, the process returns to step (42) and the above-described operation is repeated, and if it is ON, the process ends.

Further, if address mode 1~ is not ON in step (4), the process proceeds to step (44) and the series of operations cannot be repeated.

FIG. 4 is an example of program flow A.-1 showing the operation of the mask station (3). The mask station (3) sends a command to the remote station indicating that it is in the mode to the address cell 1 in step (45), and sends the address data received from the control microcomputer (2) to the stellar controller in step (46). 47) to continue sending. In step (48), it is determined whether or not the address command has been canceled, and if it has been canceled, step (49)
Performs normal transmission mode transmission and ends the process. In other words, in step (48), the control microcomputer (2)
When the set command is turned off, a command to return to normal transmission is sent to the remote station, and transmission of the address set command is ended. Also, step (48)
If the address set command has not been canceled, proceed to step (46).
) and cannot repeat the above operation.

In the above embodiment, a case was explained in which a remote station at a landing is set using a car. However, when an elevator is normally installed, after installing the equipment in the hoistway, the car is operated, and then the hall equipment is installed. Since it is installed, there is no problem with the work procedure.

In addition, when replacing a remote station at a landing due to a failure after installation, the same installation procedure can be used.

Furthermore, in the above embodiment, the case where car position data is transmitted to the remote station at the hall is explained, but the indicator information normally transmitted to the remote station at the hall is converted into an address and set only at the remote station at the hall. It is also possible.

[Effects of the Invention] As described above, according to the present invention, there is provided an elevator-evening signal transmission device that connects an elevator control unit and a plurality of terminal devices via a serial transmission path, and sends and receives data through the serial transmission path. When setting the transmission address of the terminal device, the elevator control section calculates address information from the stop position of the car, and the elevator control section transmits this address information to the terminal device and stores it. Because of this, a console is not required and the configuration is simple, and the work can be done by one person efficiently.
