Description

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

(Prior Art) Recently, with the remarkable progress of small, high-performance microcomputers, elevator control devices have also undergone major changes. However, the number of signals required to control the elevator remains the same, and a large number of input/output signal lines are connected to the control microcomputer. For example, the hall call pushbutton switch and registration display lamp installed on each floor, the elevator position display lamp, the traveling direction display lamp, the call pushbutton switch and registration lamp in the cabin, the door open command, door close command pushbutton switch, etc. The signal lines are only a small part of this, and several hundred signals in total are input to the microcomputer through each signal line.

Therefore, although microcomputers are small, high-performance, and low-priced, their characteristics cannot be fully exploited in terms of the size of the control device, manufacturing man-hours, installation work, etc.

Therefore, as a method to solve these problems, a time-division data transmission method, which has rapidly advanced and become cheaper in recent years, has been proposed and is beginning to be actually applied.

FIG. 8 shows an example of the configuration of a system for transmitting data in such a time-division manner. That is, as shown in FIG. 8, this data transmission system includes an elevator control device 1 consisting of a control microcomputer 2 and a data transmission main control section (hereinafter referred to as mask station) 3, and a plurality of data transmission systems installed on each floor of a building. The data transmission line 4 connects the transmission slave control units (hereinafter referred to as remote stations) 5a to 5d, and instructs the mask station 3 to transmit, for example, hall call data to each remote station 5a to 5d in a time-sharing manner. , and then receives data transmitted from each remote station.

Here, the functions of the remote station will be explained with reference to FIG.

When the address signal sent from the mask station 3 through the data transmission line 4 to the signal transmission control unit 9 is taken in via the transmitter receiver 10, the transmission address determination unit 16 selects the setting switch 22 (SWI to S
The receiving address is compared with the setting value set by W n ), and it is determined whether the own station is selected. When the transmission address determination unit 16 determines that the own station has been selected, the determination signal causes the elevator hall call switch 6, which is input from the data transmission/reception processing unit 15, to transmit a call signal via the transmission line 4. That's what I do.

However, in such a conventional elevator control device, the address setting values of each remote station 5a to 5d are all different, and it is necessary to individually set the address by operating the address setting switches SWI to SWn. Therefore, it takes a lot of effort and time to operate it, and furthermore, once the degree is set, the place of use, purpose, etc. are determined, making handling extremely troublesome. In addition, since addresses are set by operating the address setting switches SW1 to SWn, there is a possibility of setting errors.In particular, if duplicate addresses occur, it is important to identify the cause and defect. It's not easy either. Furthermore, after the elevator installation is completed, switch SWI~S is installed.
Even when setting Wn, the work efficiency is extremely poor if the installation location is within the elevator shaft or on top of the elevator car, and depending on how it is handled, it is quite possible to break the switch.

As a means to solve these problems, a signal transmission device has been proposed in which the mask station and remote station are provided with a function of automatically sequentially setting address data in addition to a normal data transmission function. This signal transmission device is provided with an address setting command generation section 19 as shown by the two-dot chain line in FIG. The functions of the microcomputer 2 and mask station 3 are used to sequentially set addresses for each remote station.

That is, the address information of each remote station is stored in advance in the memory of the control microcomputer 2 in the order of the address of the remote station 5a, the address of the remote station 5b, and so on. Then, when the mask station 3 switches from the normal transmission mode to the address setting transmission mode in response to the address setting command 19a from the address setting command generating section 19, it transmits the mode switching command to all remote stations.

Next, when the iu person presses the push button 6a, an address request is sent from the remote station 6a to the mask station 3, and the mask station 3 takes in the first address information stored in the memory of the control microcomputer 2. The data is transmitted to the data transmission path 4. The remote station 5a receives this address information as its own address and writes it into its own memory. in this case,
The other remote stations 5b to 5d have push button switches 6
Since the stations b to 6d are open, the address information from the data transmission path 4 is not regarded as the address of the station itself and is not received.

In this way, the coordinator presses the pushbutton switches of the remote stations one after another in a predetermined order, and the remote stations 5b to 5d receive the address information transmitted from the mask station 3 in sequence, so that each remote The station address is set.

However, such a signal transmission device has the following problems. In other words, when setting an address for each remote station, it is necessary to perform the setting operations in a certain order, so if a remote station breaks down and is replaced with a new one, only that station will be affected. Unable to set address.

Furthermore, even when correcting an incorrect address setting, the address settings must be made again from the beginning including those of other remote stations, which is a cumbersome operation.

(Problem to be Solved by the Invention) As described above, in the conventional elevator signal transmission device, since the address setting of the remote station must be performed sequentially for all stations in a fixed procedure, it is necessary to set the address for some stations, Or there was a problem that it could not be reset.

According to the present invention, addresses of remote stations can be easily set in any order, and when a remote station is replaced, addresses for some remote stations can be easily set without fail. The purpose of the present invention is to provide an elevator signal transmission device that can perform the following steps.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention includes a car position detection means for detecting the stop floor of the elevator car for the data transmission main control unit, Address storage means in which address information of the data transmission slave control unit is stored; and address storage means that stores the address data of the data transmission slave control unit of the floor corresponding to the car position detected by the car position detection means in the address transmission mode. The configuration is such that means is provided for capturing the data from the data transmission line and transmitting the data to the data transmission path.

(Function) Therefore, in the elevator signal transmission device having such a configuration, in the address setting transmission mode, the data transmission main control unit transmits the address of the data transmission slave control unit corresponding to the floor where the elevator car is stopped. Since the information is transmitted, it can be easily transmitted to any data transmission slave control unit.
Furthermore, address settings can be made with simple operations.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows one configuration example of the entire elevator signal transmission device according to the present invention. In FIG. 1, 1 is an elevator control device, and this elevator control device is a control microcomputer 2. Mask station 3 and an address setting command generation unit 19. A counter 22 that counts the output from a pulse generator 21 that generates pulses when the elevator runs and detects the car position as a pulse count value.The count value from this counter 22 is input, The car position determination section 23 determines on which floor the car is stopped, and the address data storage section 24 stores address information corresponding to each floor.

The mask station 3 sends and receives data to and from remote stations 5a to 5d installed on each floor via a transmission path 4, and also sends and receives signals such as sent and received data and transmission status to the control microcomputer 2. . Further, the address setting command generating section 19 sends an address transmission command 19a to the mask station 3 when an address setting command 2a or a manual address setting command 20 from the control microcomputer 2 is input.

FIG. 2 shows an example of the internal configuration of the mask station 3. As shown in FIG. In FIG. 2, a control signal storage section 11 stores, for example, hall display data taken in from the control microcomputer 2, and a transmission mode determination command section 7.
The control checks the state of the transmission system, the presence or absence of an address setting mode command, etc., and switches the transmission between the normal transmission mode and the address transmission mode. When the normal transmission processing section 8 is switched to the normal transmission mode by the transmission mode determination command section 7, the control signal storage section 11 transfers data to and from the control microcomputer 2 via the transmission data and status signal storage section 11 during normal transmission. It is supposed to be done. When the mode is switched to the address setting transmission mode, each address data of the address table is received from the control microcomputer 2 via the address information storage section 13, and sent to each remote station 5a to 5a through the signal transmission control section 9 and the transmitter/receiver 10. 5b.

On the other hand, FIG. 3 shows the remote station 5a shown in FIG.
This shows an example of the internal configuration of ~5d.

In FIG. 3, a signal transmission control section 9 takes in data received by a transmitter/receiver 10 and sends it to a transmission address determination section 16. The transmission address determination unit 16 monitors received data and data in the address 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. The transmission mode determination unit 17 determines a command to switch to address setting mode from the transmission data, and switches the transmission mode to address setting mode if it is determined that the address has not been set. When the data transmission/reception processing section 14 receives a permission command from the transmission mode determination section 17 and switches to the normal transmission mode,
Data is exchanged between the data input/output processing section 15 and the mask station 3. Further, when the transmission mode determination section 17 issues a permission command to the address setting transmission processing section 18 to switch to the address setting mode, this address setting transmission processing section 18 is activated by the elevator hall call switch 6.
The call signal generated by the operation is taken in through the data input/output processing section 15, determined as an address setting request signal, and the data on the data transmission path 4 is received and inputted as the address information of the own station. This address setting transmission processing section 1
The address information entered in 8 is stored in the address data storage unit 2.
1 is stored. This storage unit 21 is a rewritable ROM
is used to ensure that information does not disappear even in the event of a power outage.

Next, when describing the operation of the apparatus of this embodiment configured as described above, the functions of the control microcomputer 2, the mask station 3, and the remote stations 5a to 5d will be described with reference to FIGS. 5 to 7. This will be explained with reference to the flowchart shown in .

First, as shown in FIG. 5, the control microcomputer 2 determines whether or not it is in the address set mode in step 51, and if it is in the address set mode, step 52
The car position determined by the car position determining section 23 is input manually, and at step 53, address information corresponding to the car position is fetched from the address data storage section 24, and at step 54, the address information is transferred to the master station 3. . Then, in step 55, it is determined whether or not a set command has been input, and if the set command has been input manually, the set command is continuously given to the mask station 3, and the process returns to step 52, and the set command is inputted. If there is no input, program execution ends.

Further, when the mask station 3 is switched to the address setting mode as shown in FIG. 6, it transmits the address setting mode to the transmission line 4 in step 61, and in step 62
The address information transferred from the control microcomputer 2 is taken in at step 63, and the address information is transmitted to the transmission path 4 at step 63. Then, it is determined in step 64 whether or not the address set command has been canceled. If not, the process returns to step 62, and if it has been canceled, the normal transmission mode is transmitted to the transmission line 4 in step 65.

Furthermore, remote stations 58-5d perform step 7
Step 1 determines whether the signal transmitted from the mask station 3 is in address set mode. If it is address set mode, step 72 determines whether or not the setting is completed. If it is completed, step 72 is performed. Returning to step 71, if the process has not ended, it is determined in step 73 whether or not there is a set request input. If it is determined in this step 73 that there is a set request input, the received data is fetched and input into the memory in step 74, and the process returns to step 71 again. It ends with.

Next, the operation in the address setting mode based on each of these functions will be explained in detail. The elevator installation has now been completed,
The case where an address is set for each remote station before starting normal operation will be explained. In FIG. 1, when the elevator control device is powered on, each remote station 58 to 5d determines that the address has not been set by the transmission mode determination unit 17 shown in FIG. When the permission command is issued, the address setting transmission processing unit 18 immediately enters a state in which it receives a setting request input. In this case, the ON signal of the hall call switch SW input to the remote station is used as the setting request manual.

On the other hand, when an address transmission command 19a is issued from the control microcomputer 2 to the mask station 3 shown in FIG. 2 via the address setting command generation section 19,
The transmission mode determination command unit 7 outputs a prohibition command to the normal transmission processing unit 8 and a permission command to the address setting transmission unit 12 to switch to the address setting mode. At this point, the mask station 3 is switched to the address setting mode, and a message to that effect is sent to the control microcomputer 3 via the address information storage section 13.

When the control microcomputer 2 receives the floor position of the car from the car position determination unit 23, it stores the address data table shown in FIG. 4 (the address data storage unit 24 in FIG.
), the address data of the remote station on the corresponding floor is fetched and transmitted to the address setting transmission section 12 via the address information storage section 13. The address setting transmission unit 12 transfers the received data to the signal transmission processing unit 9. It is sent to the data transmission line 4 via the transmitter receiver 10.

The mask station and remote stage controller are now ready for address setting.

In such a state, as shown in FIG. 1, an elevator installer gets on the car, goes to the lowest floor, and turns on the hall push button 6a of the remote station 5a while the car is stopped at that floor. Then, the address setting transmission processing section 18 of this remote station 5a takes in the address data received at that time as the address of its own station, and sends it to the address data storage section 21 via the transmission address determination section 16.
to be memorized.

In this case, the elevator control device determines from the car position signal 23a of the car position determination unit 23 that the car has already stopped at the lowest floor, and converts the address data of the remote station 5a to IDX-0 shown in FIG. table (R9
Since the address of the remote station 5a is taken in from the mask station 3 and sent from the mask station 3, it means that the address of the remote station 5a is correctly set.

When the address setting for the remote station 5a on the lowest floor is completed in this way, the remote station 5a enters a standby state until it receives normal transmission from the master station 3.

This completes the address setting for the remote station 5a. Similarly, the installer stops the elevator at each floor and presses the landing button switch for that floor, thereby setting the address in the same manner as described above.

In this way, by providing the mask station 3 with the function of transmitting the address data at that time every time the elevator car position changes, the addresses of all the remote stations can be set correctly.

The above describes the address setting sequence when each remote station 58 to 5d does not have an address set.
If resetting is required for some reason after the setting is completed, a manual address setting command 20 (command from a console or a switch) is inputted to the mask station 3 via the address setting command generator 19 to put the system into address setting mode. , thereafter, mode switching is automatically performed in the same manner as described above.

Here, a case will be described in which an address is reset for a remote station that has been replaced with a new unit due to a failure of the remote station 5d on the top floor. After entering the address setting mode manually as described above, the maintenance worker gets on the elevator, travels to the top floor, and simply presses the push button switch on the platform on that floor to access mask station 3.
Since the address information of the remote station 5d on the top floor transmitted from the remote station 5d is received and stored as the address of the own station, it is possible to correctly set the address of only the replaced remote station.

In the above embodiment, a switch input to the remote station used to control the elevator is used as a trigger signal for setting the address, but the remote station may be provided with a switch exclusively for setting. Also,
If there is an indicator lamp, it is possible to ensure the address setting operation by making the lamp display a display indicating the end of address setting.

[Effects of the Invention] As described above, according to the present invention, addresses of remote stations can be easily set in any order, and when a remote station is replaced, some remote stations It is possible to provide a signal transmission device for an elevator that allows address setting to be easily performed without fail.
