2. Description of the Related Art FIG. 11 shows, for example, JP-A-4-55272.
1 is a signal transmission device for a conventional elevator, which is described in Japanese Patent Publication No. JP-A-2003-163, and in the figure, 1-3 are three elevator units #
Each unit control device (indicated as CC in the drawing) individually controls 1 to # 3 (not shown). Numerals 4, 5 and 6 are hall control devices (indicated as HS in the figure) for controlling hall equipment (hall call buttons, indicator lights, etc.) provided corresponding to each floor and each elevator alone, The hall control devices 4 ₁ to 4 _n , 5 _{1 to} 5 _n , and 6 _{1 to} 6 _n corresponding to the floors ₁ to _n are provided. 8 is connected to the hall control unit 4 and 5, a hall call button A sequence for outputting capture information such hall call, hall controller 4 ₁ to 4 _n and 5 ₁ to 5 hall call button for _n 8 ₁ to 8 _n are connected to each other. Reference numeral 9 is a B-series hall call button that is connected to the hall control device 6 and receives and outputs information such as hall calls. The hall call buttons 9 _{1 to} 9 _n are connected to the hall control devices 6 _{1 to} 6 _n , respectively. Has been done.

Reference numeral 10 denotes a group management control device (indicated by GC in the figure) which performs allocation processing of each elevator based on the hall information transmitted from the hall control devices 4 to 6, and 11 to 13 denote hall control devices 4. 6 to each of the unit control devices 1 to 3, first transmission lines 21 to 23 are second transmission lines to connect each of the unit control devices 1 to 3 and the group management control device 10. Therefore, the group management device 10 is configured so that the hall information from the hall controllers 4 to 6 is input via the respective vehicle controllers 1 to 3 and the first and second transmission paths 11 to 13 and 21 to 23. It has become.

30 is a hall control device 6 and a group management control device 1
A third transmission line connecting 0 and 33 is the first transmission line 13
Alternatively, it is a switching circuit that selectively enables one of the third transmission lines 30. In this case, the group supervisory control device 10 normally enables the first transmission path 13 for the switching circuit 33,
When an abnormality of each controller 3 is detected, the third transmission line 3
It includes an abnormality detecting means for outputting a switching signal E for making the 3 effective.

Next, the operation of the prior art will be described. First, when all of the stand control devices 1 to 3 are functioning normally, the hall information from the hall call button 8 of the A series is transmitted from the hall control device 4 to the first transmission path 11, the stand control device 1, and the stand control device 1. Second
It is taken into the group management control device 10 via the transmission line 21. Further, normally, the switching circuit 33 is connected to the contact a side as shown by a solid line, and the hall information from the hall call button 9 of the B series is transmitted from the hall controller 6 to the first transmission path 13 and each unit controller. The group management control device 1 via the third transmission line 23 and the second transmission line 23.
It is taken into 0.

If the # 1 control device 1 goes down due to power failure or transmission error, the group management control device 10
Determines an abnormality of each car controller 1, and outputs a hall information transmission control start command to each car controller 2. As a result, the control device 2 for each car takes in the hall information from the hall control device 5 via the first transmission path 12 by the hall call button 8,
It is transmitted to the group management control device 10 via the second transmission line 22. Therefore, even if each unit control device 1 goes down due to some failure or the like, the hall information can be exchanged between the hall control device 5 and the group management control device 10 via each unit control device 2, and the A series The landing call button 8 of is valid.

Next, the operation for transmitting the hall information of the B-series when the control device 3 of # 3 goes down will be described. The abnormality detection means in the group management control device 10 is the control device 3 for each unit.
Based on the transmission signal from the control unit 3, it is determined whether or not each unit control device 3 is normal, and if an abnormality in each unit control device 3 is determined, the abnormality detection means outputs the switching signal E, as indicated by the broken line. , The connection state is switched to the contact b side of the switching circuit 33. Accordingly, the hall information by the hall call button 9 is directly transmitted from the hall control device 6 to the group management control device 10 via the third transmission path 30. Therefore, even if the hall information transmission control is performed by the group management control apparatus 10 and each unit control apparatus 3 goes down, the B-series hall information is taken into the group management control apparatus 10 and becomes effective.

[0008]

In the conventional elevator signal transmission apparatus as described above, the respective vehicle control apparatuses 1 to 3 and the hall control apparatuses 4 to 6 comply with a certain transmission protocol.
Since a call button signal and an indicator signal are transmitted and received (see Japanese Patent Laid-Open No. 64-13384), each of the control devices 1 to 1
3 to the hall controller 4 having different transmission protocols
6 cannot be connected. That is, there is a problem that the hall control device of the old system cannot be used in the new system when the model of the system is changed to change the transmission protocol.

[0009] Further, in case of abnormality of each unit control device 1 or 2, the hall information is transmitted by forming a parallel transmission line, and in case of abnormality of each unit control device 3, the hall information is transmitted via the third transmission line 30. It was transmitting information. Therefore, there is a problem that the number of wiring lines 11 and 12 for the parallel transmission path, the switching signal path E, and the number of hall wiring lines such as the third transmission path 30 increases.

The present invention has been made to solve the above problems. A first object of the present invention is to increase the flexibility of hall equipment and to provide information etc. not only to equipment of the same system but also to other systems. It is intended to obtain an elevator signal transmission device capable of transmitting the signal. The second purpose is

Further, a third object is to make the hall transmission relay means always function even in the case of an abnormality due to a power failure or the like, and to reliably relay data between the hall control means and the group management control means. You get the device.

Next, regarding the operation of the transmission processing of the hall transmission relay device 14, a flow chart of the main program incorporated in the microcomputer 141 of the hall transmission relay device 14 of FIG. 4, and each unit incorporated in the microcomputer 141 of FIG. Flowchart of reception interrupt program from control device 1, microcomputer 14 in FIG.
An explanation will be given using a flow chart of the reception interrupt program from each unit control device 2 incorporated in 1.

First, the flow chart of the main program of FIG. 4 will be described. First, after initializing the UART or the like connected to the microcomputer 141 in step S1, the process proceeds to step S2.

When the process proceeds to step S2, for example, the transmission protocol 1 (for example, the transmission protocol described in Japanese Patent Laid-Open No. 64-13384) is used to serialize the transmission lines A on the individual transmission lines. The transmitted commands from the respective vehicle control devices 1 to the hall control device 4, such as display of the indicator lights, turning on and off of the arrival forecast light, are temporarily stored in the buffer area A provided in the memory 145 of the hall transmission relay device 14. Stored (FIG. 5: Steps S11 and S1)
2). In addition, according to the same transmission protocol 1, information such as a hall call from the hall control device 4 to each unit control device 1 serially transmitted on the hall transmission line 16 which is a serial transmission path is stored in the hall transmission relay device 14. Memory 145
It is temporarily stored in the buffer area C provided therein.

Then, in step S2, the data swap between the buffer area A in which the transmission / reception data with respect to each car controller 1 is temporarily stored and the buffer area C in which the transmission / reception data with the hall controller 4 is temporarily stored. Then, the data in the buffer area A and the data in the buffer area C are exchanged and stored, and then the process proceeds to step S3.

At the time of proceeding to step S3, for example, the transmission protocol 1 between each unit control device 1 and the hall control device 4 is serially transmitted on each unit transmission line B, which is a serial transmission line, by the same transmission protocol 1. In addition, the command from each car control device 2 to the hall control device 5 is sent to the buffer area B provided in the memory 145 of the hall transmission relay device 14.
Is temporarily stored in. (Refer to FIG. 6: Steps S21 and S22) In addition, according to the same transmission protocol 1, the hall control device 5 serially transmitted on the hall transmission line 16 which is a serial transmission line from the hall control device 5 to each unit control device 2, etc. Information is temporarily stored in the buffer area D provided in the memory 145 of the hall transmission relay device 14.

Then, in step S3, the data swap is performed between the buffer area B in which the transmission / reception data with each unit control device 2 is temporarily stored and the buffer area D in which the transmission / reception data with the hall control device 5 is temporarily stored. Then, the data in the buffer area B and the data in the buffer area D are exchanged and stored, and then the process proceeds to step S4.

In step S4, the data from the respective vehicle control devices 1 and 2 stored in the buffer areas C and D exchanged in step S2 and step S3 are sent to the hall control devices 4 and 5 from the address a1. When a16 is designated, serial transmission is performed on the hall transmission line 16 by the transmission protocol 1, and the hall lights and the like are displayed on the hall control devices 4 and 5 due to the hall call and the like being registered from the hall call button 8a. Send the command to turn on / off the light.
Similarly, the data from the hall control devices 4 and 5 stored in the buffer areas A and B, which have been replaced in step S2 and step S3, are sent to the control devices 1 and 2 by the transmission protocol 1 for each device. Serial transmission is performed on the transmission lines A and B, and the fact that the hall call or the like is registered is transmitted from the hall call button 8a (see FIG. 5: steps S13 and S14, FIG. 6: steps S23 and S24).

After that, the process loops to step S2, and the above steps are repeated to exchange data between the respective control devices 1 and 2 and the hall control devices 4 and 5 to perform elevator group management control.

Next, the operation of the flow chart of the program, which is incorporated in the microcomputer 141 shown in FIG. In the figure, when a reception interrupt from each unit control device 1 occurs, in step S11 the data of the reception interrupt from each unit control device 1 is received by the protocol 1 described above, and in step S12, the buffer area A in the memory 145 is received. And write to step S13. In step S13, the data from the hall control device 4 written in the buffer area A in the memory 145 is read by the above-described data swap (see FIG. 4: step S2), and the protocol is sent to each unit control device 1 in step S14. Send based on 1.

Finally, the operation of the flow chart of the program incorporated in the microcomputer 141 shown in FIG. 6 at the time of the reception interrupt processing from each unit control device 2 will be described. In the figure, when a reception interrupt from each unit control device 2 occurs, in step S21, the data of the reception interrupt from each unit control device 2 is received by the protocol 1 described above, and in step S22, the memory 145 is received.
The data is written in the buffer area B therein, and the process proceeds to step S23. In step S23, the data from the hall control device 5 written in the buffer area B in the memory 145 is read by the above-described data swap (see FIG. 4: step S3), and in step S24, each vehicle control device 2 is read.
To protocol 1 for transmission.

Next, a description will be given of a case where, for example, each of the control devices 2 is down due to power failure or transmission error. When the group management control device 10 determines an abnormality in each unit control device 2, the group management control device 10 outputs a hall information transmission control start command to the hall transmission relay device 14. In the hall transmission relay device 14 that has received the hall information transmission control start command, information such as hall calls input via the hall controller 5 (addresses a9 to a16) is temporarily stored in the transmission / reception buffer area D. So
The addresses are read again, and the addresses a9 to a16 are read into the addresses a1 to a8. Data can be swapped with buffer area A by replacing the address.
Subsequent data swapping causes the send / receive buffer area D
Each controller 1 takes in the information stored in
Relay transmission of information is performed. Also, at this time, there is information from each car control device 1 to the hall control device 5 (information notifying that each car control device 2 is down, information notifying that the car of the # 1 car has been allocated, etc.). For example, by similarly performing the address conversion process, the information is relayed and transmitted.

As a result, each car controller 1 receives the call button 8a from the hall control device 5 via the hall transmission relay device 14.
Group management control device 10 by fetching hall call information and the like by
To transmit. Therefore, even if each of the control devices 2 goes down due to some failure or the like, the hall information can be exchanged between the hall control device 5 and the group management control device 10 via the hall transmission relay device 14, and the hall call can be called. The button 8a becomes effective. At this time, since the hall address transmission relay device 14 performs the address replacement work of the hall control device 5, both the car control devices 1 and 2 may use a transmission function protocol as one car control device corresponding to a normal single car configuration. .

According to this embodiment, the hall transmission repeater 1
Each of the control devices 1 and 2 is connected to the hall control devices 4 and 5 via
, And has the same effect as before. At this time, the hall transmission relay device 14 and the hall control device 4,
5 is connected by a hall transmission line 16 which is a single serial transmission line, so that each of the control devices 1, 2
It is possible to reduce the number of hall wires between the hall and the hall control devices 4 and 5, and improve workability such as installation work and maintenance inspection.

Since the address of the information can be read by the hall call button 8a such as a hall call via the hall transmission repeater 14, the hall call buttons 8a are directly connected to the corresponding respective controllers. Since there is no need to connect the hall call button to one hall transmission relay device 14, standardization can be achieved regarding the connection of the hall call button, and the connector for connecting the hall call button to the hall transmission relay device 14 is unified. it can. Therefore, it is possible to prevent an increase in the type of hall call button, which is caused by the difference in the number of connectors for wiring connection.

Further, since the electric power for the hall transmission relay device 14 is supplied from the group management control device 10, even if one of the control devices 1 and 2 goes down due to power interruption, the system goes down. The group management control device 10 and the hall control devices 4 and 5 are connected to each other through the respective control devices, and transmission between the group management control device 10 and the hall control devices 4 and 5 can be continuously performed. .

Embodiment 2. In the above-described first embodiment, the case where the transmission protocols between the vehicle control devices 1 and 2 and the hall control devices 4 and 5 are the same has been described, but in the second embodiment, for example, the respective transmission protocols are different. The case will be described.

FIG. 7 is a block diagram showing the overall configuration of the elevator signal transmission apparatus according to the present embodiment. In the figure, 14A indicates the transmission between the control apparatuses 1 and 2 and the hall control apparatuses 70 and 71. It is a hall transmission relay device (see FIG. 8: described later) provided as a relay. Reference numeral 70 is a hall control device that controls the hall equipment (hall call buttons, indicator lights, etc.) provided corresponding to the # 1 machine, and 71 is hall equipment (hall call button that is provided corresponding to the # 1 machine. And indicator lights, etc.). Also it has a landing control device _{70 1 ~70 n, 71 1 ~71} n corresponding to each floor, respectively.

The hall control devices 70, 71 are, for example, for models different from the respective vehicle control devices 1, 2, and the transmission protocol with the hall transmission relay device 14A is different from that for the respective vehicle control devices 1, 2. Called Protocol 2)
Is doing serial communication with. In addition, the hall control device 7
A transmission address is set in each of 0 and 71. In the present embodiment, the hall control device 7 is provided for the sake of explanation.
It is assumed that 0 is given addresses a1 to a8 and the hall control device 71 is given addresses a9 to a16.
Other configurations are similar to those of the above-described first embodiment.

FIG. 8 is a block diagram showing the internal structure of the hall transmission relay device 14. In the figure, reference numeral 146 is a transmission protocol switching means, and the hall control devices 70, 71 described above are set by the switching means. It is possible to select whether to use protocol 1 or protocol 2 as the transmission protocol on the side. Other configurations are similar to those of the above-described first embodiment.

FIG. 9 is a diagram showing the internal mapping of the transmission-related part of the memory 145. In the figure, 40A is the entire transmission memory area, 41 is the transmission / reception data with each unit controller 1 corresponding to the # 1 machine. Are temporarily stored in buffer areas A and 42, and buffer areas B and 45 which temporarily store data transmitted / received to / from each unit control device 1 corresponding to the # 2 machine.
Is a buffer area E for temporarily storing transmission / reception data to / from the hall controller 70 (addresses a1 to a8) and 71 (addresses a9 to a16).

Next, the operation of the transmission process of the hall transmission relay device 14A will be described with reference to the flowchart of the main program incorporated in the microcomputer 141 of the hall transmission relay device 14A of FIG. First, in step S31, initialization of a UART or the like connected to the microcomputer 141 is performed, and the microcomputer 141 performs transmission processing according to the protocol 2 with the hall control devices 70 and 71, and the memory mapping 40A.
Recognize. Then, it transfers to step S32.

When the process proceeds to step S32, for example, the transmission protocol 1 (for example, the transmission protocol described in Japanese Patent Laid-Open No. 64-13384) is used to serialize each serial transmission line A on each transmission line A. The transmitted command from each unit control device 1 to the hall control device 4 is temporarily stored in the buffer area A provided in the memory 145 of the hall transmission relay device 14. In addition, a hall call from the hall controller 4 to each unit controller 1 serially transmitted on the hall transmission line 16 which is a serial transmission line by a transmission protocol 2 different from the transmission protocol 1,
Information such as commands to the hall indicators is transmitted to the hall transmission relay device 14
Is temporarily stored based on the addresses a1 to a8 set in the buffer area E provided in the memory 145.

Then, in step S32, the data swap is performed between the buffer area A in which the transmission / reception data with the individual vehicle controller 1 is temporarily stored and the buffer area E in which the transmission / reception data with the hall controller 70 is temporarily stored. Then, the data in the buffer area A and the data in the buffer area E are exchanged and stored, and then the process proceeds to step S33.

When shifting to step S33, for example, serial transmission is performed on each unit transmission line B, which is a serial transmission line, by the same transmission protocol 1 as the transmission protocol between each unit control device 1 and the hall control device 71. The command issued from each unit control device 2 to the hall control device 5 is temporarily stored in the buffer area B provided in the memory 145 of the hall transmission relay device 14. In addition, according to the transmission protocol 2, the hall control device 71 serially transmitted on the hall transmission line 16 that is a serial transmission line from the hall control device 71 to each of the control devices 2.
Information such as a hall call to the hall is temporarily stored based on the addresses a1 to a8 set in the buffer area E provided in the memory 145 of the hall transmission repeater 14A.

Then, in step S33, the data swap between the buffer area B in which the transmission / reception data with respect to each car controller 2 is temporarily stored and the buffer area E in which the transmission / reception data with the hall controller 71 is temporarily stored. Then, the data in the buffer area B and the data in the buffer area E are exchanged and stored, and then the process proceeds to step S34.

In step S34, the data from the respective vehicle control devices 1 and 2 stored in the buffer area E exchanged in step S32 and step S33 are sent to the hall control devices 70 and 71 at addresses a1 to a16. The designation and protocol conversion by the transmission protocol switching unit 146 serially transmits on the hall transmission line 16 by the transmission protocol 2, and to the hall control devices 70 and 71 with the hall call and the like being registered from the hall call button 8a. The command to display the indicator light, turn on and off the arrival forecast light is transmitted. Similarly, steps S2 and S3
The data from the hall control devices 70 and 71 stored in the buffer areas A and B exchanged by the above are transmitted to the respective control devices 1 and 2 by the transmission protocol 1 for each transmission line A,
Serial transmission is performed on B, and the fact that a hall call or the like has been registered is transmitted from the hall call button 8a.

After that, the process loops to step S2, and the above steps are repeated to exchange data between the control devices 1 and 2 and the hall control devices 4 and 5 to perform elevator group management control.

Next, a case will be described in which, for example, each of the control devices 2 is down due to power failure or transmission error. When the group management control device 10 determines an abnormality in each unit control device 2, the group management control device 10 outputs a hall information transmission control start command to the hall transmission relay device 14A. The hall transmission repeater 14A that has received this hall information transmission control start command is operated by the hall controller 71.
Since information such as a hall call input via (addresses a9 to a16) is temporarily stored in the transmission / reception buffer area E, the addresses are replaced and the addresses a9 to a9 are read.
16 is replaced with addresses a1 to a8. By replacing the address, data swapping with the buffer area A becomes possible, and by the subsequent data swapping, the information stored in the transmission / reception buffer area E is taken in by each controller 1, and relay transmission of information is performed. In addition, at this time, if there is information from each of the control devices 1 to the hall control device 71, the address conversion process is similarly performed to relay the information.

In addition, each car controller 1 to the hall controller 7
Address a of buffer area A when transmitting data to 1
1 to a8 are replaced with addresses a9 to a16 and transmitted. At the time of transmission to the hall control device 71, the transmission protocol switching means 146 performs protocol conversion by the protocol conversion and transmits.

As a result, each unit control device 1 fetches the hall call information and the like by the hall call button 8a from the hall control device 71 via the hall transmission relay device 14A and transmits it to the group management control device 10. Therefore, even if each of the control devices 2 goes down due to some failure or the like, the hall information can be exchanged between the hall control device 71 and the group management control device 10 via the hall transmission relay device 14A. The button 8a becomes effective. At this time, since the address transfer operation of the hall control device 71 is performed by the hall transmission relay device 14A, both the vehicle control devices 1 and 2 may be transmission function protocols as one vehicle control device corresponding to a normal single car configuration. .

According to this embodiment, the hall transmission repeater 1
4A, the control devices 1 and 2 are connected to the hall control device 71,
It is connected to 71 and the same effect as Embodiment 1 mentioned above can be produced. Further, the hall transmission relay device 14A is provided with a transmission protocol switching means 146, and the transmission protocol for serial transmission from the hall transmission relay device 14A to the hall control devices 70, 71 can be switched within a preset range, and the connected model. Even if the transmission protocol is changed due to different reasons or due to maintenance, etc., it is possible to reliably support the changed transmission protocol, so it is possible to increase the flexibility of the hall equipment, let alone equipment of the same system, It is possible to unify the hall equipment between other systems.

In the above-described first and second embodiments, the case where two cars are connected to the hall transmission repeater has been described, but the same applies to a single car and other multi-car configurations. By providing the transmission relay device, the above-described effects can be achieved.

The platform control means or the hall control means corresponding respectively to the hall data transmitted from the plurality of hall control means via the serial transmission path or the control data transmitted from the plurality of each vehicle control means via the serial transmission path. Landing transmission having a transmission relay unit that relays to send to another vehicle, and a transmission protocol conversion unit that converts any one protocol into the other protocol so as to match the transmission protocol between each vehicle control means and the hall control means. Since the relay means is provided, even if the model of a plurality of landing control means connected via the serial transmission path is different or the transmission protocol is changed due to maintenance or the like, the changed transmission protocol is surely supported. It is possible to improve the flexibility of hall equipment, and to unify hall equipment between other systems as well as equipment of the same system. It can be. Also, at this time,
The hall transmission relay means for switching to the transmission protocol corresponding to each connected hall control means appropriately switches a plurality of transmission protocols on the serial transmission path, and it is necessary to provide a transmission path and a transmission protocol switching device corresponding to each transmission protocol. Therefore, the workability of installation work, maintenance and inspection can be improved.

Further, an address for each hall control means is designated and held with respect to the hall data from the plurality of hall control means, and each car control corresponding to the control data from each of the plurality of car control means is controlled. The address of each means is designated and held, and when an abnormality of each platform control means is detected, the addresses of the plurality of hall control means corresponding to each platform control means having the abnormality are not abnormal. Since the hall transmission relay means for converting into an address corresponding to each other vehicle control means is provided, it is possible to reduce the number of hall wiring between the hall transmission relay means and the hall control means, and control each vehicle, for example. Even if one of the means or the like becomes uncontrollable due to the power interruption, the group management control means and the hall control means are connected via each other unit control means that is not down, and the group management control means and the hall are connected. control Transmission of information between the stages can be carried out continuously, backup system by accident can be established.

Further, since the driving power of the hall transmission relay device is supplied from the group management means for controlling the allocation of the cars, the hall transmission relay means is always operated while the elevator control is carried out by the group management means. It can be driven, information can be transmitted and relayed reliably, and reliability of information transmission in elevator control is improved.
