Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to an elevator control signal transmission device for transmitting 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 elevator control does not change, and a large number of input / output signal lines are connected to the control microcomputer. For example, signals such as hall call push button switches and registration display lamps installed on each floor, elevator position display lamps, traveling direction display lamps, call push button switches and registration lamps in the car, door opening command, door closing command push button switch, etc. The line is a very small part of the line, in which several hundreds of signals are input to the microcomputer through the respective signal lines.

Therefore, the microcomputer 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 includes an elevator controller 1 including a control microcomputer 2 and a data transmission main control unit (hereinafter referred to as a master station) 3 and a plurality of data transmission sub-control units (hereinafter referred to as remote control units). Called station) 5a ~
5d is connected by a data transmission line 4, and the master station 3 issues a command to each remote station 5a to 5d to transmit, for example, hall call data in a time division manner, and subsequently the data transmitted from each remote station. It is intended to receive.

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

When the address signal sent from the master station 3 to the signal transmission control unit 9 through the data transmission path 4 is taken in through the transmitter receiver 10, the transmission address determination unit 16 sets the setting switch 22 (SW1 to SWn). The set value thus set is compared with the reception address to determine 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.
In 14, the call signal from the elevator hall call switch 6 input from the data input / output processing unit 15 is transmitted via the transmission line 4.

However, in such a conventional elevator control device, since the address setting values of the remote stations 5a to 5d are all different, and further, it is necessary to set the addresses individually by operating the address setting switches SW1 to SWn. However, the operation takes a lot of time and labor, and once set, the place of use, purpose, etc. are determined, which makes handling extremely troublesome. In addition, since the address is set by operating the address setting switches SW1 to SWn, it is possible that a set error may occur. In particular, if an address overlap occurs, it is not easy to find the cause and defective product. Absent. In addition, even if the switches SW1 to SWn are set after the elevator installation work, the workability is extremely poor if the installation location is within the elevator shaft, above the elevator car, etc. It is possible.

(Problems to be solved by the invention) As described above, in the conventional elevator control signal transmission device, since the addresses assigned to the remote stations 5a to 5d are individually set by the address setting switches, Not only is it time-consuming and time-consuming, but it also causes a set error.

Therefore, according to the present invention, by providing the master station and the remote station with a function capable of automatically setting address data in addition to the normal data transmission function, the address of each remote station can be accurately set by a very simple operation. It is an object of the present invention to provide an elevator control signal transmission device that can be used.

Are connected by a data transmission line, the control signal output from the elevator control unit is taken into the data transmission master control unit, and this control data is sent to each data transmission slave control unit via the data transmission line. In an elevator control signal transmission device that divides and transmits, when an address setting command or a manual address setting command from the elevator control unit is input to the elevator control device, an address setting mode command is sent to the data transmission main control unit. An address setting command generating means is provided, and each of the data transmission slave control units receives the data transmitted from the data transmission master control unit. Data and the data in the address storage unit of the own data transmission slave control unit, the transmission address that determines the selection of the own data transmission slave control unit, the reception of the transmission mode command, and the address unset state of the own data transmission slave control unit When it is determined that the determining unit and the transmission address determining unit select the own data transmission slave control unit and receive the normal mode command, the transmission mode is set to the normal transmission mode,
Further, when it is determined that the address is not set, the transmission mode determining means for switching the transmission mode to the address setting mode, and the normal mode between the data transmission main control section when the transmission mode determining means switches to the normal transmission mode. Data transmission / reception processing means for delivering and receiving transmission data during transmission, and an address for outputting a call signal by a hall call switch to the data transmission main control unit as an address setting request command when the transmission mode determination means switches to the address setting mode. The data transmission main control unit is provided with setting transmission processing means, and determines whether the transmission system state or the address setting mode command from the address setting command generating means determines whether the transmission mode is the normal transmission mode or the address transmission mode. The transmission mode judgment command means for switching the transmission and the transmission mode judgment command means When switched to the normal transmission mode, the normal transmission processing means for receiving the transmission data and the status signal at the time of the normal transmission from the elevator control section and transmitting them to the respective data transmission slave control sections, and the address transmission mode by the transmission mode determination command means. When it is switched to, each address data is received from the elevator control unit, and the presence or absence of the address request command input from each data transmission slave control unit is monitored to send the address data to the data transmission slave control unit having the address request command. And an address setting transmission means for transmitting.

(Operation) Therefore, in the elevator control signal transmission device having such a configuration, the address transmission command is given from the address setting generation means to the data transmission main control unit, and the data transmission main control unit is set to the address transmission mode. When switched, the address setting data is fetched from the elevator control section, and it is determined whether or not the address is set in each data transmission sub-control section. If not set, the mode is switched to the address setting mode and the data transmission main control section is set. By issuing an address setting request to the data transmission master control unit, the address setting data fetched from the elevator control unit is sequentially transmitted to each data transmission slave control unit, and the corresponding address setting data is set in each data transmission slave control unit. By taking in the data and storing it, the address of the own data transmission slave control unit is set.

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 the entire elevator control signal transmission apparatus according to the present invention. In FIG. 1, reference numeral 1 is an elevator control device, and the elevator control device 1 is composed of a control microcomputer 2, a master station 3 and an address setting command generating section 19. The master station 3 transmits / receives data to / from the remote stations 5a to 5d installed on each floor via the transmission path 4, and also transmits / receives data such as transmitted / received data and transmission state to / from the control microcomputer 2. .
The address setting command generator 19 sends an address transmission command 19a to the master station 3 when the address setting command 2a or the manual address setting command 20 from the control microcomputer 2 is input.

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 control signal storage unit 11 sends the transmission data and the status signal at the time of normal transmission to the microcomputer 2 via the control signal storage unit 11. It is designed to be handed over. When the transmission mode determination command unit 7 switches the address setting transmission unit 12 to the address transmission mode, the address setting transmission unit 12 receives each address data of the setting address table from the microcomputer 2 via the address information storage unit 13, and the signal transmission control unit 9 And to each remote station 5a-5d via the transmitter / receiver 10.

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 determination unit 17 is a transmission address determination unit
When it is determined in 16 that the own station is selected, the transmission mode is switched to the normal transmission mode, and when it is determined that the address is not set, the transmission mode is switched to the address setting mode. The data transmission / reception processing unit 14 exchanges data between the data input / output processing unit 15 and the master station 3 when the transmission mode determination unit 17 issues a permission command to switch to the normal transmission mode. In addition, from the transmission mode determination unit 17, the address setting transmission processing unit 18
When the permission command is issued to switch to the address setting mode, a call signal by operating the elevator hall call switch 6 is taken in through the data input / output processing unit 15, and this is taken as an address setting request signal and the signal transmission control unit 9 and the transmitter. It is transmitted to the master station 3 through the receiver 10. The call signal by operating the elevator hall call switch 6 is similarly input to the data transmission / reception processing unit 14 when the normal mode is switched. The address data storage unit 21 stores address setting data corresponding to the own station transmitted from the master station 3 when the address of the own station is not set. A rewritable ROM is used as the storage unit 21 so that information cannot be lost even in the event of a power failure or the like.

Next, the operation of the apparatus of the present embodiment configured as described above will be described. The case where the installation of the elevator is now finished and the address is set to each remote station before the normal operation starts will be described. In Fig. 1, when the power of the elevator controller is turned on, each remote station
For 5a to 5d, the transmission mode determination unit 17 shown in FIG. 3 determines that the address is not set, and the permission command is issued to the address setting transmission processing unit 18. Then, the address setting transmission processing unit 18 immediately waits for 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 the control microcomputer 2 issues an address transmission command 19a to the master station 3 shown in FIG. 2 via the address setting command generation unit 19, the transmission mode determination command unit 7 causes the normal transmission processing unit 8 to operate. Prohibition command,
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 is sent to the control microcomputer 2 via the address information storage unit 13, the control microcomputer 2 sends the address setting storage unit 13 to the address setting transmission unit 12 via the address information storage unit 13. Each address data of the address data table as shown in the figure is input. In this address setting transmission unit 12, the pointer IDX of the address data is set to the head thereof, that is, the first data of the data table is sent to the first address element. After that, each remote station 5a ~
Waiting for the address request signal from 5d.

As a result, the master station and remote station are ready for address setting. In such a state, in FIG. 3, the elevator installer switches the remote station landing call switch SW from 6a to 6
b, 6c …… Turn on. First, when the landing call switch 6a of the first remote station 5a is turned on, the address setting transmission processing unit 18 of the remote station 5a detects the ON signal as an address setting request input, and the address request signal is transmitted to the signal transmission control unit 9, It is transmitted to the master station 3 via the transmitter / receiver 10 and waits for the reception of address data.

The master station 3 shown in FIG. 2 receives the address request signal (RQ1 corresponding to RS1 in FIG. 7) from the remote station 5a, and first, the first data of the address data shown in FIG. Send AD1) corresponding to the MS in FIG. The remote station 5a shown in FIG. 3 receives this data as the unique address data of its own station, and the transmission address determination unit 16 writes this data in the address data storage unit 21. When the writing of the address data is completed, the remote station 5a waits until the normal transmission command is received from the master station 3.

Thus, the address setting of the remote station 5a is completed. Similarly, the elevator installer operates the call registration switches 6b, 6c ... At each elevator according to the order of IDX in the address data table of FIG. The master station 3 sends an address every time one address is sent.
IDX is sequentially advanced, and the address data of FIG. 6 (MS of FIG. 7)
AD2 ... ADn) corresponding to each remote station 5b, 5
Address request for c ... (RQ2 corresponding to RS2 in Fig. 7, ...
RSn corresponding to RSn) is sequentially transmitted, and after the transmission of all addresses is completed, a normal transmission mode command is transmitted and the address setting transmission of the remote station is completed.

The above is the description of the address setting sequence when each remote station 5a to 5d has not set the address, but if it is necessary to reset the address for some reason after the setting is completed, manually set the address setting command 20 (by console or switch) to set the address. Master station 3 via generator 19
By inputting to the address setting mode of the system, the mode switching is automatically performed in the same manner as described above, and the address can be reset.

Here, the details of the operation of each of the remote stations 5a to 5d and the master station 3 described above will be described with reference to the flowcharts shown in FIGS. 4 and 5. In the remote stations 5a-5d,
As shown in FIG. 4, first, it is determined whether or not the address setting is completed, and if not, it is determined whether or not the address setting request input is turned on. When it is determined that the address setting request input is on,
Send an address request signal to the master station.
Then, it is judged whether or not the address data sent from the master station is received, and if it is judged that the address data is received, this address data is set as the address of the own station. After the address of the own station is set in this way, it is judged whether or not the normal mode command sent from the master station is received, and if it is judged that the normal mode command is received, the own station command is received. Waiting, and if it is determined that the address setting mode command is received, data transmission in the normal mode is performed.

On the other hand, as shown in FIG. 5, the master station first sets the address setting mode, then inputs the address data table and transmits the address setting mode command. Next, from the address data table, the address ID
Set X at the beginning and wait for the reception of the address request signal from the remote station.If it is determined that this address request signal has been received, the address data corresponding to IDX is transmitted, and transmission of all addresses is completed. If it is judged whether or not the transmission of all addresses is not completed, the IDX is advanced one by one, and if it is judged that the transmission of all addresses is completed, the normal transmission command is transmitted to transmit normal data. Be started.

As described above, in the present embodiment, the address transmission command 19 is sent from the address setting command generator 19 to the master station 3.
When a is given, this master station is switched to the address transmission mode by the transmission mode determination command unit 7,
Address setting data is sent from the control microcomputer 2 via the address information storage unit 13 to the address setting transmission unit 12
The transmission mode determination unit 17 at each remote station simultaneously determines whether or not an address has been set.If it is not set, the address setting mode is switched to the master station from the address setting transmission processing unit 18. 3 outputs an address request signal, and when the address setting transmission unit 12 of the master station 3 receives this address request signal, the address setting data fetched from the control microcomputer 2 is sent to each remote station 5a-5d.
Since the transmission address determination unit 16 of each remote station 5a to 5d fetches the corresponding address setting data and stores it in the address data storage unit 21, the address of the remote station is set. can do.

Therefore, even if the address of each remote station is not set by the address setting switch as in the conventional case, the address setting command generation unit 19 causes the master station 3 to operate.
When the address transmission command 19a is input to the address setting mode, the transmission mode determination command unit 7 switches to the address setting mode by the permission command output to the address setting transmission unit 12, and the address setting automatically transmitted from the master station 3 is set. Since the address is set by the data, the address of each remote station can be set accurately by a very simple operation.

In the above embodiment, the input signal for controlling the remote station is used as the address request signal. However, the unit itself of the remote station may be provided with a push button switch and the address request signal may be issued by pushing this switch. . Further, although the remote station is configured to automatically enter the address setting mode when the address is not set, it may be set to the address setting mode after receiving the mode switching command of the master station.

[Effects of the Invention] As described above, according to the present invention, since the master station and the remote station are provided with the function of automatically setting address data in addition to the normal data transmission function, complicated work can be performed. It is possible to provide an elevator control signal transmission device capable of extremely easily and accurately setting the addresses of a large number of remote stations by simply pressing a switch without performing the operation.
