Description

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

(Related Art) In recent years, the remarkable progress of small and high-performance microcomputers has greatly changed elevator control devices. However, the number of signals required for controlling the elevator does not change, and a number of input / output signal lines are connected to the microcomputer for control. For example, signals such as a hall call push button switch and a registration display lamp mounted on each floor, an elevator position display lamp, a traveling direction display lamp, a call push button switch and a registration lamp in a car, a door open command, a door close command push button switch, and the like. The lines are only a small part of the lines, and hundreds of signals are input to the microcomputer through each signal line.

Therefore, macro computer is small, high performance,
In spite of its low price, its characteristics could not be fully exhibited in terms of the size, man-hours, and installation work of the control device.

Therefore, as a method of solving such a problem, a time-division data transmission method which has been rapidly advanced in recent years and has become inexpensive has been proposed and actually applied.

FIG. 8 shows a configuration example of a system for transmitting data in such a time-division manner. That is, as shown in FIG. 8, this data transmission system comprises an elevator control device 1 comprising a control microcomputer 2 and a data transmission main control unit (hereinafter referred to as a master station) 3 and a plurality of data provided on each floor of the building. A transmission slave control unit (hereinafter referred to as a remote station) 5a to 5d is connected by a data transmission line 4, and a command is sent from the master station 3 to each of the remote stations 5a to 5d in a time-division manner, for example, to transmit hall call data. , And then receive data transmitted from each remote station.

Here, the function of the remote station will be described with reference to FIG.

When an address signal transmitted from the master station 3 through the data transmission path 4 is taken into the signal transmission control section 9 via the transmitter receiver 10, the transmission address determination section 16 sets the address signal by the setting switches 22 (SW1 to SWn). By comparing the set value with the reception address, it is determined whether or not the own station is selected. When the transmission address determination section 16 determines that the own station has been selected, the data transmission / reception processing section receives the determination signal.
A call signal from the elevator hall call switch 6 input from 15 is transmitted via the transmission line 4.

However, in such a conventional elevator control device, the address setting values of the remote stations 5a to 5d are all different, and furthermore, the addresses need to be individually set by operating the address setting switches SW1 to SWn. However, this operation takes a lot of trouble and time, and once set, the place of use, purpose, and the like are determined, which makes the handling extremely troublesome. In addition, since the address is set by operating the address setting switches SW1 to SWn, a setting mistake can be considered. In particular, if the address is duplicated, it is easy to find the cause and the defect. is not. Furthermore, even if the switches SW1 to SWn are set after the elevator installation work, the workability is extremely poor when the installation location is inside the elevator shaft, on the elevator car, etc. It is possible.

As means for solving these problems, there has been proposed a signal transmission device in which a master station and a remote station have a function of automatically and sequentially setting address data in addition to a normal data transmission function. This signal transmission device is provided with an address setting command generation unit 19 as shown by a two-dot chain line in FIG. 8, gives an address setting command 19a to the master station 3, switches the transmission mode to the address setting transmission mode, Microcomputer 2
And the function of the master station 3 is 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. When the master station 3 is switched from the normal transmission mode to the address setting transmission mode by the address setting command 19a from the address setting command generator 19, the mode switching command is transmitted to all the remote stations.

Next, when the adjuster presses push button 6a, the remote station
An address request is transmitted from 6a to the master station 3. The master station 3 fetches the first address information stored in the memory of the control microcomputer 2 and transmits it to the data transmission path 4. The remote station 5a receives this address information as its own station address and writes it in its own memory. In this case, since the other remote stations 5b to 5d have the push button switches 6b to 6d open, the address information from the data transmission path 4 is not regarded as the address of the own station and is not received.

As described above, the coordinator presses the push button switches of the remote stations in the determined order, and the remote stations 5b to 5d receive the sequentially determined address information transmitted from the master station 3. Is set.

However, such a receiving and transmitting apparatus has the following disadvantages. In other words, when setting an address for each remote station, it is necessary to perform the setting operation in a certain order. Therefore, if a remote station breaks down and is replaced with a new station, only that station is replaced. The address cannot be set. Also, when correcting an address setting error, the address must be reset from the beginning, including for other remote stations, and the operation for that is troublesome.

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

According to the present invention, the address setting of the remote station can be performed easily and in any order, and the address setting for some of the remote stations is definitely performed by a simple operation when the remote station is replaced. It is an object of the present invention to provide an elevator signal transmission device capable of performing the following.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a car position detecting means for detecting a stop floor of an elevator car with respect to a data transmission main control unit, and the car floor detecting means for each floor. Address storage means for storing address information of the data transmission slave control unit, and address data of the data transmission slave control unit at the floor corresponding to the car position detected by the car position detection means in the address transmission mode. In this configuration, there is provided a means for further taking in and transmitting the data to the data transmission path.

(Operation) Therefore, in the elevator signal transmission device having such a configuration, the data transmission slave control unit corresponding to the floor where the elevator is stopped from the data transmission main control unit when in the address setting transmission mode. Since the address information is transmitted, it is possible to easily and easily set an address for an arbitrary data transmission slave controller by a simple operation.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

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

The master station 3 transmits and receives data to and from the remote stations 5a to 5d installed on each floor via the transmission line 4, and also transmits and receives signals such as transmission / reception data and transmission status to / from the control microcomputer 2. . When an address setting command 2a or a manual address setting command 20 from the control microcomputer 2 is input, the address setting command generating section 19 outputs the master station 3
The address transmission command 19a is sent to the

FIG. 2 shows an example of the internal configuration of the master station 3. In FIG. 2, a control signal storage unit 11 stores, for example, hall display data taken from the control microcomputer 2, and a transmission mode determination command unit 7.
Checks the status of the transmission system and the presence or absence of an address setting mode command, and performs transmission switching between the normal transmission mode and the address transmission mode. When the normal transmission processing unit 8 is switched to the normal transmission mode by the transmission mode determination command unit 7, the transmission of the transmission data and the status signal at the time of the normal transmission is performed with the control microcomputer 2 via the control signal storage unit 11. It has become. When the address setting transmission mode is switched, each address data of the address table is received from the control microcomputer 2 via the address information storage unit 13 and transmitted to each of the remote stations 5a to 5b via the signal transmission control unit 9 and the transmitter receiver 10. To be transmitted.

FIG. 3 shows the remote station 5a shown in FIG.
5d shows an example of the internal configuration. In FIG.
The signal transmission control unit 9 takes in the data received by the transmitter receiver 10 and sends it to the transmission address determination unit 16. The transmission address determination unit 16 monitors the received data and the data in the address storage unit 21 of the own station, and determines the selection of the own station, the reception of the transmission mode command, the address unset state of the own station, and the like. The transmission mode determining unit 17 determines a command to switch to the address setting mode from the transmission data, and switches the transmission mode to the address setting mode when it is determined that the address has not been set. The data transmission / reception processing unit 14 exchanges data between the data input / output processing unit 15 and the master station 3 when a permission command is issued from the transmission mode determination unit 17 and the mode is switched to the normal transmission mode. When the mode is switched to the address setting mode by issuing a permission command from the transmission mode determining unit 17 to the address setting transmission processing unit 18, the address setting transmission processing unit 18 inputs and outputs a call signal by operating the elevator hall call switch 6. The data is fetched via the processing unit 15 and determined as an address setting request signal, and the data on the data transmission path 4 is received and input as address information of the own station. The address information input to the address setting transmission processing unit 18 is recorded in the address data storage unit 21. The storage unit 21 uses a rewritable ROM so that information is not erased even in the event of a power failure or the like.

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

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

When the master station 3 is switched to the address setting mode as shown in FIG. 6, the address setting mode is transmitted to the transmission line 4 in step 61, and the address information transferred from the control microcomputer 2 in step 62. The address information is transmitted to the transmission line 4 in step 63. Then, it is determined in step 64 whether or not the address set command has been released. If the address set command has not been released, the process returns to step 62 again. If it has been released, the normal transmission mode is transmitted to the transmission line 4 in step 65.

Further, the remote stations 5a to 5d determine in step 71 whether or not the signal transmitted from the master station 3 is in the address set mode, and in the case of the address set mode, determine in step 72 whether or not the setting is completed. If it has been completed, the process returns to step 71. If it has not been completed, it is determined in step 73 whether a set request has been input. If it is determined in step 73 that there is a set request input, the received data is fetched in step 74 and input to the memory, and the process returns to step 71 again.
The process ends when it is determined in step 71 that the mode is not the address set mode.

Next, the operation in the address setting mode based on these functions will be described in detail. Now, a case will be described in which the installation of the elevator is completed and an address is set to each remote station before starting normal operation. In FIG. 1, when the power of the elevator control device is turned on, each of the remote stations 5a to 5d determines that the address has not been set by the transmission mode determining unit 17 shown in FIG. Is issued, the address setting transmission processing unit 18 immediately has 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 input.

On the other hand, when an address transmission command 19a is issued from the control microcomputer 2 to the master station 3 shown in FIG. Prohibition directive,
An enable command is output to the address setting transmission unit 12 to switch to the address setting mode. At this point, Master Station 3
Is switched to the address setting mode, and that is sent to the control microcomputer 3 via the address information storage unit 13.

When the floor position of the car is inputted by the car position judging section 23, the control microcomputer 2 receives the address data table shown in FIG. 4 (the address data storage section 2 shown in FIG. 1).
4) The address data of the remote station on the corresponding floor is fetched and transmitted to the address setting transmission unit 12 via the address information storage unit 13. Address setting transmission section
At 12, the received data is transmitted to the data transmission path 4 via the signal transmission processing unit 9 and the transmitter receiver 10.

Thus, the master station and the remote station are ready for address setting. In such a state, in FIG. 1, the elevator installer gets on the car, goes to the lowest floor, and turns on the landing end button 6a of the remote station 5a with the car stopped on that floor. Then, the address setting transmission processing section 18 of the remote station 5a fetches the address data received at that time as the address of its own station, and the transmission address determination section 16
Through the address data storage unit 21.

In this case, the elevator control device determines that the car is already stopped at the lowest floor by the car position signal of the car position determination unit 23.
23a, the address data of the remote station 5a is fetched from the IDX = 0 table (address of RS1) shown in FIG. 4 and transmitted from the master station 3, so that the address of the remote station 5a is correct. It will be set.

When the address setting for the lowermost floor remote station 5a is completed, the remote station 5a
5a stands by until the normal transmission from the master station 3 is received.

Thus, the address setting of the remote station 5a is completed. Similarly, the installer sets the address in the same manner as described above by pressing the hall stop button switch on that floor while stopping the elevator on each floor.

By providing the master station 3 with a function of transmitting the address data at that time every time the elevator car position changes, all the remote stations are set with the correct addresses.

In the above, the address setting sequence when each of the remote stations 5a to 5d has not set an address has been described. However, when resetting is required for some reason after the setting is completed, the manual address setting command 20 (command by console or switch) is set to the address setting command. By inputting the generator to the master station 3 via 19 and setting the system to the address setting mode, the mode switching is automatically performed thereafter 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 manually setting the address setting mode as described above, the maintenance staff gets on the elevator, travels to the top floor, and presses the pushbutton switch of the landing on that floor, and then presses the master 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 exchanged remote station.

Although the switch input to the remote station used for controlling the elevator is used as the trigger signal for setting the address in the above embodiment, a switch dedicated to setting may be provided in the remote station. In addition, if a display lamp is provided, a display indicating the end of the address setting of the lamp is performed, so that an effect that the address setting operation can be surely performed is obtained.

[Effects of the Invention] As described above, according to the present invention, the address setting of the remote stations can be performed easily and in any order, and some remote stations can be set when the remote stations are replaced. It is possible to provide an elevator signal transmission device that can undoubtedly perform address setting with a simple operation.
