Description

Elevator control device and elevator control method

The present invention relates to an elevator control device and an elevator control method.

Control devices used in industrial machines in recent years may take the form of connecting controlled objects with a 1: 1 communication path. As a result, compared to the form in which the control targets are connected by a 1: N communication path, since there is always one device connected to the communication path, the amount of wiring between the control targets is reduced and communication noise is also reduced. , Communication speed can be expected to improve.

Taking an elevator, which is one of the industrial machines, as an example, the elevator is a main controller for each unit that controls the operation of the riding basket, a hoisting controller that raises and lowers the basket, a basket controller that controls the inside of the basket, and an elevator. It consists of a sub-controller that controls the equipment installed in the hall. Equipment installed in the elevator hall includes a hall button for calling a basket, a display for displaying the arrival of the basket, and the like.
When each device constituting these elevators is connected by a 1: 1 communication path, the sub-controllers installed in the elevator hall are installed on each floor of the building, so the sub-controllers are connected in a string. ..

In the form of connecting the control targets with a 1: 1 communication path in this way, the control targets are expanded by connecting them in a string of beads. When multiple devices are connected in a string, if one control target fails or the communication path is cut off, subsequent communication will not be possible, affecting the entire system. For example, in the case of an elevator, if the sub-controller that controls the hall button on a specific floor cannot communicate, the sub-controller on another floor that communicates via that sub-controller cannot communicate.
It is essential to ensure the reliability of industrial machines such as elevators, and it is also necessary to ensure the reliability of the communication functions of each device provided in the elevator system.

Patent Document 1 describes a technique for ensuring reliability by duplicating a communication path between a control device and a communication partner.

Japanese Unexamined Patent Publication No. 10-198618

In the field of communication equipment, as described in Patent Document 1, it has been conventionally known to duplicate communication paths in order to ensure reliability.
However, when the technology for duplicating communication paths is applied to elevators, if the number of floors of the building to be installed is large, a large number of sub-controllers are required to be installed on each floor, and the number of duplicating communication paths becomes very large. There is a problem that the system configuration becomes complicated.
In elevators, it is desired to ensure reliability while preventing the communication path of the sub-controllers installed on each floor from becoming complicated.

An object of the present invention is to provide an elevator control device and an elevator control method that can ensure reliability without complicating the configuration for communication.

In order to solve the above problems, for example, the configuration described in the claims is adopted.
The present application includes a plurality of means for solving the above problems. For example, based on the control of the main controller that controls the unit of the own system, the basket that carries the user or luggage, and the control of the main controller. It is an elevator control device including a hoisting controller that moves the car up and down and a plurality of sub controllers installed on each floor where the car moves up and down, and is a plurality of communication paths for connecting the main controller and the plurality of sub controllers. It has a loop-shaped communication path in which the sub-controllers of the above are connected in order.

As a result, the main controller and the sub-controller on each floor are connected by substantially multiple routes, and even if a communication abnormality occurs, the sub-controller is maintained in a state where it can communicate as much as possible, and the user is unable to do so. The reduction in pleasure and vehicle allocation efficiency can be minimized.

<Example of the first embodiment>
Hereinafter, examples of the first embodiment of the present invention will be described with reference to FIGS. 1 to 15.

[overall structure]
FIG. 1 shows a schematic configuration of the entire elevator system in which the elevator control device of the first embodiment is installed.
The elevator system shown in FIG. 1 includes two elevators, a first unit and a second unit. In FIG. 1, the components of the elevator of Unit 1 are assigned a code of "a", and the components of the elevator of Unit 2 are assigned a code of "b" to distinguish them. However, in the following description, when the unit is not specified, it will be described with reference numerals without "a" and "b".
The configuration of the elevator of Unit 1 and the configuration of the elevator of Unit 2 are basically the same. When explaining the configuration, the first unit will be explained, and the explanation of the configuration of the elevator of Unit 2 will be one. The part is omitted.
Further, in FIG. 1, each unit is shown as an elevator that goes up and down from the first floor to the fourth floor, but the number of floors that the elevator goes up and down is an example.

The elevators of Unit 1 are the main controller 101a of Unit 1, the hoisting controller 102a, the basket 103a, the rope 104a, the sub-controllers 105a-1 to 105a-4 on each floor, and the hall buttons 106a-1 to 106a on each floor. -4 and.
Similarly, the elevators of Unit 2 include the Unit 2 main controller 101b, the hoisting controller 102b, the basket 103b, the rope 104b, the sub-controllers 105b-1 to 105b-4 on each floor, and the hall buttons 106b- on each floor. 1 to 106b-4 are provided.
In FIG. 1, the units and floors are shown in parentheses on the sub-controllers 105a-1 to 105a-4 and 105b-1 to 105b-4 on each floor. For example, the sub-controller 105a-1 on the first floor of Unit 1 is shown as (1-1F) in FIG.

The first main controller 101a allocates the car 103a based on the information from the car 103a and the information of the sub-controllers 105a-1 to 105a-4, and outputs an operation command to the car dispatch floor to the winding controller 102a. Control to do.

The winding controller 102a is a control device that raises and lowers the basket 103a in accordance with the command of the first main controller 101a.
The basket 103a performs a process of transmitting data of devices such as a destination floor button and an open / close button installed in the basket on which the user or luggage is loaded to the first main controller 101a. Further, the basket 103a performs a process of transmitting the data transmitted from the Unit 1 main controller 101a to a device installed in the basket such as a floor display unit.

The rope 104a connects the winding controller 102a and the basket 103a. By winding the rope 104a with the winding controller 102a, the basket 103a moves up and down.

The sub-controllers 105a-1 to 105a-4, which are terminals installed on each floor, perform a process of transmitting the data of the hall buttons 106a-1 to 106a-4 installed in the hall to the main controller 101. Further, the sub-controllers 105a-1 to 105a-4 perform a process of transmitting the data transmitted from the first main controller 105a to a display (not shown) or the like installed in the hall.
The hall buttons 106a-1 to 106a-4 are installed in the halls that are the elevator landings on each floor, and are up and down buttons that the user presses to call the basket 103a from the elevator hall.

The sub-controllers 105a-1 to 105a-4 on each floor are sequentially connected to the first main controller 101a by using communication paths 107a and 108a so as to be able to communicate in both directions.
That is, the Unit 1 main controller 101a is communicably connected to the sub-controller 105a-4 on the 4th floor of the Unit 1 by the communication path 107a.
Further, the four sub-controllers 105a-1, 105a-2, 105a-3, 105a-4 of the first unit are connected in order by the communication path 108a, respectively.

Explaining the second unit as well, the second unit main controller 101b is communicably connected to the sub-controller 105b-4 on the fourth floor of the second unit by a communication path 107b.
Further, the four sub-controllers 105b-1, 105b-2, 105b-3, 105b-4 of the second unit are connected in order by the communication path 108b, respectively.
By providing the communication paths 107a, 107b, 108a, 108b in this way, assuming that the main controllers 101a and 101b of each unit are upstream and the sub-controllers 105a-1 and 105b-1 at the ends are downstream, transmission is performed from the upstream. A communication path is constructed in which data is transmitted downstream and data transmitted from the downstream is transmitted upstream.

Then, in the case of the present embodiment, a communication path 109 is provided to connect the sub-controller 105a-1 at the end of the first machine and the sub-controller 105b-1 at the end of the second machine. The communication path 109 is a communication path provided to realize duplication of communication.

When duplicating communication, a method of duplicating the communication path 108a between the sub-controllers 105a-1 to 105a-4 can be considered as a conventional general method. On the other hand, in the example of the present embodiment, as shown in FIG. 1, devices having a short physical distance, such as between the terminal sub-controllers 105a-1 and 105b-1, are connected by a communication path 109 and duplicated. As a result, the amount of wiring can be reduced for the entire system.
Further, by duplicating between the sub-controllers 105a-1 and 105b-1 installed on the first floor, it is easy for the wiring operator to access, so that the workability can be improved.

As shown in FIG. 1, it is an example that the communication path 109 connects the sub-controller 105a-1 at the end of Unit 1 and the sub-controller 105b-1 at the end of Unit 2, and other parts. You may connect with. That is, the communication path 109 includes any one of the sub-controllers 105a-1 to 105a-4 of the first unit and any one of the sub-controllers 105b-1 to 105b-4 of the second unit. , Just connect.

Explaining the other communication paths shown in FIG. 1, the communication path 110a is a communication path between the Unit 1 main controller 101a and the basket 103a. The communication path 111a is a communication path between the first unit main controller 101a and the winding controller 102a.
The communication path 112 is a communication path between the Unit 1 main controller 101a and the Unit 2 main controller 101b. By using this communication path 112 to send and receive information on each sub-controller 105a-1 to 105a-4, 105b-1 to 105b-4, communication status information, etc., the efficiency of vehicle allocation and maintainability are improved. Is possible.

As described above, in the embodiment of the present embodiment, the sub-controller 105a-1 of the first unit is controlled by the second main controller 101b, which is a separate system, using the communication path 109. By connecting to and making the communication path ring-shaped, the communication path is duplicated. For example, even when a failure occurs in any one of the sub-controllers 105a-1 to 105a-4, the communication path can be bypassed and controlled. As a result, the car can be dispatched even when a communication abnormality occurs. In addition, the failure range can be specified even when two or more failures occur. 8 to 11 will be described later as an example of a method for identifying a failure location and a range.

[Main controller configuration]
FIG. 2 shows a configuration viewed from the function of the Unit 1 main controller 101a. In the following description, the configuration of the Unit 1 main controller 101a will be described, but the Unit 2 main controller 101b has the same configuration as the Unit 1 main controller 101a, and description and illustration thereof will be omitted.

The first unit main controller 101a includes an inter-hole transmission / reception unit 201, an inter-basket transmission / reception unit 202, a hoisting machine transmission / reception unit 203, an inter-machine transmission / reception unit 204, a terminal communication state storage unit 205, and a call information storage unit 206. , And a basket information storage unit 207.

The inter-hole transmission / reception unit 201 is a processing unit that transmits / receives to / from the sub-controllers 105a-1 to 105a-4, and transmits terminal communication status packets, terminal route setting packets, and various hall control information. Further, the inter-hall transmission / reception unit 201 receives a reply of the terminal communication status packet and control information (such as call information of the hall button).

The inter-basket transmission / reception unit 202 is a processing unit that transmits / receives to / from the basket 103a, transmits a control command of the device in the basket to the basket 103a, and receives information on the device in the basket from the basket 103a.
The hoisting machine transmission / reception unit 203 is a processing unit that transmits / receives to / from the hoisting controller 102a, transmits a hoisting command to the vehicle allocation floor to the hoisting controller 102a, and receives hoisting information from the hoisting controller 102a. The Unit 1 main controller 101a uses this hoisting information to detect an abnormality in the hoisting portion and the like.

The inter-unit transmission / reception unit 204 is a processing unit that transmits / receives to / from the unit main controller 101b of another system, and transmits / receives information of each sub-controller 105b-1 to 105b-4 controlled by the unit main controller 101b of another system. ..
The terminal communication status storage unit 205 stores the terminal communication status packets returned from the sub-controllers 105a-1 to 105a-4.
The call information storage unit 206 stores the call information of each of the sub-controllers 105a-1 to 105a-4.
The basket information storage unit 207 stores device information, destination floor command information, and the like in the basket 103.

The communication status / route generation unit 208 generates terminal communication status packets in order to check the communication status of each of the sub-controllers 105a-1 to 105a-4. The first main controller 101a broadcasts the terminal communication status packet to each of the sub-controllers 105a-1 to 105a-4, and each of the sub-controllers 105a-1 to 105a-4 adds a value to the received packet and returns it. Check the communication status of each sub-controller 105a-1 to 105a-4.
Further, the communication state / route generation unit 208 generates a terminal route setting packet that enables / disables the communication path of each of the sub-controllers 105a-1 to 105a-4. The first main controller 101a broadcasts this terminal route setting packet to each sub-controller 105a-1 to 105a-4, refers to the terminal route setting packet by each sub-controller 105a-1 to 105a-4, and each sub-controller. The second transmission / reception unit 302 (FIG. 4) of 105a-1 to 105a-4 is enabled or disabled.

The hall control command generation unit 209 generates a hall control command from the information of the sub-controllers 105a-1 to 105a-4 stored in the call information storage unit 206 and the basket information stored in the basket information storage unit 207. It is a control device. For example, the hall control command generation unit 209 performs processing such as lighting the button when the hall button is pressed and lighting the lantern installed in the hall when the basket 103 arrives.

The car dispatch command generation unit 210 optimally dispatches the car 103a from the information of the sub-controllers 105a-1 to 105a-4 stored in the call information storage unit 206 and the car 103a stored in the car information storage unit 207. This is a processing unit that generates commands.
The communication map creation unit 211 performs a process of generating a communication map of the sub controller from the terminal communication status packet stored in the terminal communication status storage unit 205.

The mode setting unit 212 is a processing unit that switches the mode of the car dispatch command based on the communication map generated by the communication map creation unit 211. The modes are roughly classified into a normal mode and a degenerate mode. The normal mode is a mode when communication is normal. The degenerate mode is a mode in which communication between the first main controller 101a and each of the sub-controllers 105a-1 to 105a-4 is abnormal at one or more locations.

In the example of the present embodiment, in the degenerate mode, the user can change the operation method of the elevator by using the communication abnormality range created by the communication map and the vehicle allocation command which is the basket information and the call information. Take measures to minimize the discomfort and reduction of vehicle allocation efficiency. Details of the specific operation method will be described later.

The display unit 213 displays the mode information switched by the mode setting unit 212 and the communication abnormality range created by the communication map creation unit 211. By presenting this information to building managers and maintenance personnel, it is possible to quickly deal with abnormalities and improve maintainability.
In the case of a configuration in which a plurality of units are installed as shown in FIG. 1, the display unit 213 may be shared by the plurality of units.

[Controller hardware configuration example]
The main controllers 101a and 101b of each unit are composed of, for example, a computer device and its peripheral devices.
FIG. 3 shows an example of hardware configuration when the first main controller 101a is configured by a computer device.
The computer device that functions as the first main controller 101a includes a CPU (Central Processing Unit) 221 connected to the bus, a ROM (Read Only Memory) 222, and a RAM (Random Access Memory) 223, respectively. .. Further, the computer device includes a non-volatile storage 224, a network interface 225, an input device 226, and a display unit 213.

The CPU 221 is an arithmetic processing unit that reads a program code of software that executes arithmetic processing and authentication processing for controlling an elevator from ROM 222 and executes it. Variables, parameters, etc. generated during the arithmetic processing are temporarily written in the RAM 223.

For the non-volatile storage 224, for example, a large-capacity information storage unit such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) is used. The non-volatile storage 224 functions as each storage unit 205, 206, 207, and stores information stored in each storage unit 205, 206, 207. However, it is an example that the non-volatile storage 224 is used as each storage unit 205, 206, 207, and even if a part or all of each storage unit 205, 206, 207 is used by another storage medium such as RAM 223. good.

For the network interface 225, for example, a NIC (Network Interface Card) or the like is used. This network interface 225 functions as each transmission / reception unit 201, 202, 203, 204.
The input device 226 is composed of a keyboard, a mouse, and the like for input operations by the building manager and maintenance personnel.
The display unit 213 displays various states of the elevator including the mode information and the communication abnormality range described in the configuration of FIG.

Note that FIG. 3 shows an example in which the Unit 1 main controller 101a is configured by a computer device. Similarly, the Unit 2 main controller 101b, the hoisting controller 102a, and the sub-controllers 105a-1 to 105a-4 can also be configured by a computer device.
Alternatively, each controller may be configured by a device other than a computer device that performs arithmetic processing. For example, some or all of the functions performed by the main controllers 101a and 101b of each unit may be realized by hardware such as FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit).

[Subcontroller configuration]
FIG. 4 shows the configuration of the sub-controllers 105a-1 to 105a-4. The sub-controllers 105a-1 to 105a-4 installed on each floor have the same configuration.
Each of the sub-controllers 105a-1 to 105a-4 includes a first transmission / reception unit 301, a second transmission / reception unit 302, a communication state addition unit 303, a communication route setting unit 304, a hall information transmission / reception unit 305, and an ID analysis unit. It is composed of 306.

The first transmission / reception unit 301 is a processing unit that transmits / receives data from the upstream portion, assuming that the main controllers 101a and 101b of each unit are the upstream portion and the opposite direction of the path is the downstream portion. The second transmission / reception unit 302 is a processing unit that transmits / receives data from the downstream unit.
The data transmitted and received by the first transmission / reception unit 301 and the second transmission / reception unit 302 includes terminal communication status packets transmitted from the main controllers 101a and 101b of each unit, terminal route setting packets, and sub-controllers 105a-1 to 105a. The control information received in -4 is included.

As a basic communication flow using the first transmission / reception unit 301 and the second transmission / reception unit 302, upstream data is transmitted downstream, and downstream data is transmitted upstream to broadcast data to the entire system. It is a method. At this time, the ID analysis unit 306 analyzes the ID of the data received by the first transmission / reception unit 301, and distributes the received data to each processing unit.

The communication state addition unit 303 adds the communication state data of its own sub-controller to the terminal communication state packet transmitted from the first unit main controller 101a, and broadcasts it in the upstream direction and the downstream direction.
The communication route setting unit 304 refers to the terminal route setting packet received from the first unit main controller 101a, and performs a process of enabling or disabling the second transmission / reception unit 302. By making this setting, when the communication path is duplicated, if the communication is normal, the control signal does not have to be transmitted to the duplicated path, so that the processing load of the entire system can be reduced.
For example, when communication is normal, the second transmitter / receiver 302 of the sub-controller 105a-1 (1st floor of Unit 1: 1-1F) and the sub-controller 105b-1 (1st floor of Unit 2: 2-1F). By disabling, you don't have to send and receive unnecessary packets. Further, at the time of setting to enable or disable, for example, by enabling or disabling each packet, necessary packets are broadcast and unnecessary packets are not transmitted, so that the processing load can be reduced and the processing can be simplified.

[Communication packet configuration]
FIG. 5 shows a terminal communication status packet 410 transmitted from each of the main controllers 101a and 101b, a terminal route setting packet 420, and control information 430 required to control each of the sub-controllers 105 and the basket 103.
The terminal communication status packet 410 is composed of, for example, an area 411 indicating the terminal communication status packet (ID1) and areas 412 to 419 for storing the communication status of each terminal. As shown in FIG. 1, when each unit has four sub-controllers 105a-1 to 105a-4 and 105b-1 to 105b-4, the areas 412 to 419 for storing the communication status of each terminal. Is the total number of sub-controllers in eight areas.

When the terminal communication state packet 410 is generated by the main controllers 101a and 101b of each unit, for example, the areas 412 to 419 corresponding to each sub-controller 105 are all transmitted as 0.
Each of the sub-controllers 105a-1 to 105a-4 and 105b-1 to 105b-4 returns, for example, the area allocated to the own terminal of the received terminal communication status packet as "1".
In this way, the sub-controllers 105a-1 to 105a-4 and 105b-1 to 105b-4 return the status of the own terminal, and the main controllers 101a and 101b of each unit check 1 of the communication status of each terminal. You can check the communication status between your own unit and the terminals of other units.

The terminal route setting packet 420 is a packet that enables / disables the second transmission / reception unit 302 of the sub controller 105. The terminal route setting packet 420 is composed of an area 421 indicating a terminal communication status packet (ID2) and areas 422 to 429 for storing the route setting of each terminal.
Specifically, the valid / invalid settings of the sub-controllers 105a-1 to 105a-4 are stored in the areas 422 to 429 of each terminal of the terminal route setting packet 420, and in the case of "1", the corresponding terminal The second transmission / reception unit 302 of is enabled, and if it is "0", it is disabled.
In the case of this setting method, not only the second transmission / reception unit 302 is simply enabled / disabled by the numerical values "0" and "1", but also other numerical values, for example, numerical values after "2" are used. You may set enable / disable for each packet.

The control information 430 is a control packet of each of the sub-controller 105, the basket 103, and the hoisting controller 102 required to control the elevator.
The control information 430 is composed of a region 431 indicating the control information (ID2) and a control information 432 instructing the control content.

[Mode display example]
FIG. 6 shows an example in which the display unit 213 (FIG. 2) displays the mode.
The mode display screen 510 has a communication mode 511 and a terminal communication state 512, and the mode display screen 510 displays the communication mode of each unit main controller 101 and the communication state of the terminal.
In the communication mode 511, the distinction between the normal mode and the degraded mode of each unit is displayed.
The terminal communication status 512 indicates whether the communication status with the terminal of each unit is normal or abnormal. When the terminal communication status 512 displays an abnormality, the terminal on any floor is also displayed as abnormal.
For example, in the example of FIG. 6, it is shown that the second unit is in the degenerate mode, the terminal communication state 512 is set, and "an abnormality has occurred in the abnormal terminal 2" is displayed, and the sub controller 105b-2 of the second unit has a communication abnormality. Displays that it is in the degraded mode.

FIG. 7 shows a list display screen 520 of the status of the sub-controller 105 of each unit for displaying the mode and the communication status shown in FIG.
In the list display screen 520 shown in FIG. 7, all the sub-controllers of the first unit are normal, and in the second unit, the sub-controllers on the second floor indicate a communication abnormality. Further, for the Nth machine (N is an arbitrary number of 3 or more), it indicates that the sub-controllers at a plurality of locations have communication abnormalities.
When the sub-controllers at a plurality of locations have communication abnormalities, the status of the sub-controllers 105 sandwiched between the two or more communication abnormal locations cannot be confirmed, and therefore, it is displayed as unknown on the list display screen 520.
In addition, in order to confirm the state of the sub controller 105 in each unit main controller 101 in any failure pattern of the sub controller 105, each sub controller 105 has a communication path for communicating with the main controller 101 of the corresponding unit and is duplicated. It is also possible to do it.

By displaying the mode and communication status as shown in FIGS. 6 and 7, the abnormal range can be quickly confirmed, which makes it possible to improve efficiency in the event of failure or maintenance. In addition, even when there is an abnormality in two or more communication paths, the abnormal range of communication can be determined.

[Example of terminal communication status packet generation processing]
FIG. 8 shows an example of generating a terminal communication state packet 410 during normal communication. In FIG. 8, the terminal communication state packet 410 is shown as packets 601, 602, 603, 604 in which the values "1" or "0" of the four terminal states of the two units are set. The first stage of packets 601, 602, 603, and 604 shows the four terminal states of the first machine, and the second stage shows the four terminal states of the second machine.

The terminal communication status packet 410 is generated by the communication status / route generation unit 208 of the main controllers 101a and 101b of each unit, and is transmitted in the downstream direction. Here, when transmitting from the main controllers 101a and 101b of each unit, the terminal communication status is set to "0". That is, as shown in FIG. 8, the terminal communication status packet 601 transmitted for the first time by the Unit 1 main controller 101a is set to "0" in all terminal communication statuses.
Similarly, for the terminal communication status packet 602 transmitted by the Unit 2 main controller 101b for the first time, the terminal communication status is set to "0".

When each sub-controller 105 receives the terminal communication status packets 601, 602, only the area of its own main controller 105 is set to "1", and it is broadcast in the upstream direction and the downstream direction.

For example, the terminal communication status packet 601 transmitted from the first main controller 101a is finally received by the sub-controller 105b-4 on the fourth floor of the second unit, and the sub-controller 105b-4 sets the area of the communication status. When it is set to "1", it is broadcast in the upstream direction and the downstream direction. The communication status can be confirmed by receiving the finally broadcast packets 603 and 604 in the main controllers 101a and 101b of each unit and analyzing them by the communication map creation unit 211.
In the case of the example of FIG. 8, all the sub-controllers 105 are in normal communication, and in the finally received packets 603 and 604, the values of the sub-controllers on all floors of all the units are "1".

FIG. 9 shows a case where the sub-controller 105a-3 on the third floor of the first unit fails and a communication abnormality occurs.
First, the terminal communication status packet 601 transmitted by the first main controller 101a for the first time and the terminal communication status packet 602 transmitted by the second main controller 101b for the first time are all 0 in the terminal communication status. It is the same as the example of 8.

Here, because the sub-controller 105a-3 on the third floor of the first unit is out of order, the main controller 101a of the first unit finally receives the terminal communication status packet 603 shown in FIG. In this terminal communication status packet 603, only the sub-controller 105a-4 on the 4th floor of the 1st unit between the main controller 101a of the 1st unit and the sub-controller 105a-3 on the 3rd floor of the 1st unit can communicate normally. Yes, the state is "1", and the states of all other terminals remain "0".

In addition, the terminal communication status packet 604 is finally received by the Unit 2 main controller 101b. In this terminal communication status packet 604, all the sub-controllers 105b-1 to 105b-4 of the second machine and the two sub-controllers 105a-1 and 105a-2 of the first machine can communicate normally, and the state is changed. It is "1", and the state of the other two sub-controllers 105a-3 and 105a-4 of Unit 1 is "0".

In such a case, the main controllers 101a and 101b of each unit transmit the respective terminal communication status packets 603 and 604, and the communication map creation unit 211 combines terminals whose status is "1", so-called OR condition. Then, one terminal communication state packet 605 is generated. That is, in the case of FIG. 9, as the terminal communication state packet 605, only the sub-controller 105a-3 on the third floor of the first unit indicating an abnormality has a value “0” indicating an abnormality, and the other sub-controllers 105a-1, 105a- 2,105a-4, 105b-1, 105b-2, 105b-3, 105b-4 all have a value "1" indicating normality.
From the terminal communication status packet 605 created by the communication map creation unit 211, it can be seen that the main controllers 101a and 101b of each unit have a communication abnormality in the sub-controller 105a-3 on the third floor of the first unit.

FIG. 10 shows an example in which a communication abnormality occurs at two locations. That is, the case where the sub-controller 105a-3 on the third floor of the first unit and the sub-controller 105b-2 on the second floor of the second unit fail and a communication abnormality occurs is shown.
In the state shown in FIG. 10, the first main controller 101a finally receives the terminal communication state packet 603 shown in FIG. In this terminal communication status packet 603, only the sub-controller 105a-4 on the 4th floor of the first unit can communicate normally, the status is "1", and the status of all other terminals remains "0". ..
Further, the Unit 2 main controller 101b finally receives the terminal communication state packet 604 shown in FIG. In this terminal communication status packet 604, only the sub-controller 105b-3 on the 3rd floor of Unit 2 and the sub-controller 105b-4 on the 4th floor of Unit 2 can communicate normally, and the status is "1". The status of all terminals remains "0".

Therefore, the terminal communication status packet 605 finally created by the communication map creation unit 211 is the sub-controller 105a-4 on the 4th floor of the first unit and the sub-controllers 105b-3 on the 3rd and 4th floors of the second unit. , 105b-4 is the value "1" indicating normality. Here, any of the sub-controllers 105a-2, 105a-1, 105b-1 between the sub-controller 105a-3 on the third floor of Unit 1 and the sub-controller 105b-2 on the second floor of Unit 2 Communication is not possible even on the route, the state is unknown, and the value indicating the state remains "0".
By connecting the sub-controllers 105a-1 and 105b-1 of the plurality of systems by the communication path 109 shown in FIG. 1, the communication status can be confirmed by bypassing the communication, and the communication abnormality can be confirmed. Range can be specified.

FIG. 11 shows an example in which a communication abnormality occurs at two locations of one unit (Unit 2). That is, the case where the sub-controller 105b-1 on the first floor of the second unit and the sub-controller 105b-3 on the third floor of the second unit fail and a communication abnormality occurs is shown.
Even in the state shown in FIG. 11, in the terminal communication state packet 604 that is finally generated, these two sub-controllers 105b-1 and 105b-3 and the sub-controller 105b-2 in between are set to the value ". It is "0", and the other states are "1".

[Processing example on the main controller]
FIG. 12 is a flowchart showing processing by the main controllers 101a and 101b of each unit.
Here, the operation of the Unit 1 main controller 101a will be described as an example.
First, when the Unit 1 main controller 101a is activated and the process is started (step S1001), the Unit 1 main controller 101a transmits the control information received by the transmission / reception units 201, 202, 204 to the storage units 205, 206, 207. Store (step S1002). Next, the communication state / route generation unit 208 generates a terminal communication state packet, and the inter-hole transmission / reception unit 201 transmits it to each sub-controller 105 (step S1003).

Further, the communication state / route generation unit 208 generates a terminal route setting packet, and the inter-hole transmission / reception unit 201 transmits it to the sub controller 105 (step S1004).
Further, the hall control command generation unit 209 generates a hall control command and transmits it to the sub controller 105 by the inter-hole transmission / reception unit 201 (step S1005). After that, the communication map creation unit 211 reads the terminal communication status packet from the terminal communication status storage unit 205 and creates a communication status map (step S1006). The Unit 1 main controller 101a determines the communication status from the created communication map, and determines whether it is normal or abnormal (step S1007).

In this step S1007, if a communication error occurs (No in step S1007), the inter-machine transmission / reception unit 204 reads the terminal communication status packet of the unit main controller 101b of another system (unit 2) (step S1008). Then, in the main controller 101a of the own unit, a communication map is created and a mode is set by taking an OR condition in which the terminal communication status packet of the main controller 101a of the own unit and the terminal communication status packet of the main controller 101b of the other unit are combined. The generated communication map is transmitted to unit 212 (step S1009).

Further, in step S1007, if the communication is normal (Yes in step S1007), the communication map generated by the main controller 101a of the own unit is transmitted to the mode setting unit 212 (step S1010).

Then, after the transmission in step S1009 or S1010, the mode setting unit 212 transmits the vehicle allocation mode of the car allocation command generation unit 210 according to the communication map, and transmits the mode information to the display unit 213 (step S1011).
The display unit 213 displays the received mode information (step S1012).
Further, the car dispatch command generation unit 210 determines the mode received from the mode setting unit 212 (step S1013). When the normal mode is determined in step S1013 (Yes in step S1013), the car dispatch command generation unit 210 performs normal operation (step S1014). If it is determined in step S1013 that the mode is not the normal mode (No in step S1013), the car dispatch command generation unit 210 sets the degenerate mode and performs the degenerate operation (step S1015). Finally, the Unit 1 main controller 101a determines whether the process is completed (step S1016), returns to step S1003 when continuing the process (No in step S1016), and returns to step S1003 when the process is completed (step S1016). Yes), the process end process is performed (step S1017).
Although the processing by the Unit 1 main controller 101a has been described so far, the processing is also performed in the Unit 2 main controller 101b according to the flowchart of FIG.

[Example of processing in normal mode and degenerate mode]
Next, the details of the operation in the normal mode in step S1014 and the operation in the degenerate mode in step S1015 of the flowchart of FIG. 12 will be described.

FIG. 13 is a flowchart showing a process during operation in the normal mode in step S1014.
When the normal operation is started (step S1101), the car dispatch command generation unit 210 reads out the information of the car call by the hole button from the call information storage unit 206, and the destination to the button operation in the car from the car information storage unit 207. Read the floor registration information (step S1102).
Then, the car dispatch command generation unit 210 determines whether or not there is a vehicle dispatch command from the read information (step S1103). When it is determined in step S1103 that there is a vehicle allocation command (Yes in step S1103), vehicle allocation is assigned based on the information and the current car position, and the vehicle allocation command is transmitted to the hoisting machine transmission / reception unit 203 (step S1104).

When it is determined in step S1103 that there is no vehicle allocation command (No in step S1103), and after issuing the vehicle allocation command in step S1104, the car dispatch command generation unit 210 ends the normal operation process (step S1105), and step S1101 Return to the start processing of.
During this normal operation, when there is a hall button operation on each floor, a process of moving the baskets 103a and 103b to that floor is performed.

FIG. 14 is a flowchart showing a process during operation in the degenerate mode in step S1015.
When the degenerate operation is started (step S1106), the car dispatch command generation unit 210 reads the information of the car call by the hole button from the call information storage unit 206, and the information of the button operation in the car from the car information storage unit 207. Is read (step S1107). The car call information stored in the call information storage unit 206 during the degenerate operation is the information from the sub controller 105 that can communicate normally, and the car call information from the sub controller 105 on the floor where the abnormality has occurred is the information from the sub controller 105. Not registered.
Then, the car dispatch command generation unit 210 determines whether or not there is a vehicle dispatch command from the read information (step S1108). When it is determined in step S1108 that there is a vehicle allocation command (Yes in step S1108), vehicle allocation is assigned based on the information and the current basket position, and the vehicle allocation command is transmitted to the hoisting machine transmission / reception unit 203 (step S1111).

On the other hand, when it is determined in step S1108 that there is no vehicle allocation command (No in step S1108), the car dispatch command generation unit 210 refers to the communication map (step S1109). The state in which there is no vehicle allocation command to be No in step S1108 is a state in which there is no car call information from each sub-controller 105 capable of normally communicating, and there is no button operation in the car 103.

Then, the car dispatch command generation unit 210 assigns the vehicle dispatch command to the floor of the sub-controller 105 of the communication abnormality from the referenced communication map (step S1110). Here, when there are a plurality of sub-controllers 105 with communication abnormalities, the car dispatch command generation unit 210 issues a vehicle allocation command to sequentially stop the car 103 on a plurality of floors on which the sub-controllers 105 with communication abnormalities are installed.

After issuing the vehicle allocation command in step S1111 and assigning to the communication abnormal floor in step S1110, the car dispatch command generation unit 210 ends the degenerate operation process (step S1112), and starts the process of step S1106. Return to.

In this way, when the sub-controller 105 with communication error exists, when there is no basket call from any floor and there is no registration of the destination floor by button operation in the basket, the elevators are stopped in order to the floor where communication error occurred. Degenerate operation will be performed, and the elevator will be available even on the floor where communication is abnormal.

For example, in the case of the example of FIG. 9, the car dispatch command generation unit 210 of the Unit 1 main controller 101a dispatches the vehicle to the third floor where the communication is abnormal in the vehicle allocation in step S1111.
Further, in the case of the example of FIG. 10, the car dispatch command generation unit 210 of the Unit 1 main controller 101a dispatches the vehicle in step S1111 to stop the vehicle in order on the first floor, the second floor, and the third floor where the communication is abnormal. .. In addition, the car dispatch command generation unit 210 of the Unit 2 main controller 101b dispatches the vehicle to the first floor and the second floor, which have communication abnormalities, in order in the vehicle allocation in step S1111.
Further, in the case of the example of FIG. 11, the car dispatch command generation unit 210 of the Unit 2 main controller 101b dispatches the vehicle in step S1111 to stop the vehicle in order on the first floor, the second floor, and the third floor where the communication is abnormal. ..

As described above, in the embodiment of the present embodiment, even if an abnormality occurs in the communication between the main controller 101 and the sub controller 105 of each unit, normal operation is performed within the range in which normal use is possible, and degeneration is performed during the normal operation. By not driving, the discomfort of the user can be minimized. Further, in the example of the present embodiment, the degenerate operation is performed only in the communication abnormal range created by the communication map, and the frequency and range of the degenerate operation can be minimized.

[Processing example with sub-controller]
FIG. 15 is a flowchart showing processing in each sub-controller 105.
First, when the sub-controller 105 starts and starts processing (step S1201), the first transmission / reception unit 301 receives information from the upstream (step S1202). Then, the ID analysis unit 306 analyzes the received data (step S1203).
The ID analysis unit 306 determines whether or not the received data is a terminal route setting packet based on the analysis result of the received data (step S1204). Further, in step S1204, if it is not a terminal route setting packet (No in step S1204), the ID analysis unit 306 determines whether or not the received data is a terminal communication state packet (step S1205).

Then, when it is determined in step S1204 that the packet is a terminal route setting packet (Yes in step S1204), the first transmission / reception unit 301 transmits the received data to the communication route setting unit 304 (step S1206). Then, the communication route setting unit 304 sets the communication route of the second transmission / reception unit 302 based on the received data (step S1206).
Further, when it is determined in step S1205 that the packet is a terminal communication state packet (Yes in step S1205), the first transmission / reception unit 301 transmits the received data to the communication state addition unit 303 (step S1208).
Then, the data to which the communication state is added by the communication state addition unit 303 is transmitted to the first transmission / reception unit 301 and the second transmission / reception unit 302 (step S1209).

Further, when it is determined in step S1205 that the packet is not a terminal communication state packet (No in step S1205), it is control information, and the first transmission / reception unit 301 transmits data to the hall information transmission / reception unit 305 (step S1210). Then, the hall information transmission / reception unit 305 transmits information to a device such as the hall button 106 (step S1211).

Then, after the processing of steps S1207, S1209, and S1211, the packet in which the first transmission / reception unit 301 is set is broadcast to the upstream communication path, and the packet in which the second transmission / reception unit 302 is set is sent to the downstream communication path. It is transmitted by broadcast (step S1212).
After that, the sub-controller 105 determines whether or not the processing is completed (step S1216). If the process is not completed in step S1216 (No in step S1216), the sub-controller 105 returns to the process in step S1202. Further, when it is determined in step S1216 that the process is completed (Yes in step S1216), the sub controller 105 performs the end process (step S1217).
By performing such processing in the sub controller 105, the main controller 101 of each unit can collect the data of the communication state described with reference to FIGS. 5 to 11.

As described above, the elevator control device of the present embodiment includes communication paths 107, 108, 109, so that the main controller 101 of each unit provides information on whether communication with each sub controller 105 is normal or abnormal. Can be properly collected, and appropriate operation control can be performed based on the collected information.
Further, as an operation based on the communication state with each sub-controller 105, even if an abnormality occurs in which communication with some sub-controllers 105 cannot be performed, the normal operation is performed within the range in which normal use is possible, and during the normal operation. By not performing degenerate operation, the discomfort of the user can be minimized. Further, in the example of the present embodiment, the degenerate operation is performed only in the communication abnormal range created by the communication map, and the frequency and range of the degenerate operation can be minimized. Since the range of this communication abnormality is determined by connecting the sub-controllers 105 in a loop on the communication routes 107, 108, 109, it is possible to perform the same good abnormality determination as when the communication routes are duplicated.

<Example of the second embodiment>
Next, an example of the second embodiment of the present invention will be described with reference to FIG. In FIG. 16, the same parts as those in FIGS. 1 to 15 of the first embodiment described above are designated by the same reference numerals, and duplicate description will be omitted.

An example of the second embodiment of the present invention is the case of an elevator composed of one unit.
That is, in the example of the present embodiment, as shown in FIG. 16, as the elevator control device, the first main controller 101a and the sub-controllers 105a-1, 105a-2, 105a-3, 105a-4 on each floor are used. Be prepared. FIG. 16 shows an example of four floors, but the number of floors is an example.
The configurations shown in FIGS. 2 and 4 are applied to the first main controller 101a and the sub-controllers 105a-1, 105a-2, 105a-3, 105a-4 on each floor.

Then, the sub-controllers 105a-1 to 105a-4 on each floor are sequentially connected to the first main controller 101a by communication paths 107a and 108a so as to be able to communicate in both directions.
That is, the Unit 1 main controller 101a is communicably connected to the sub-controller 105a-4 on the fourth floor by the communication path 107a.
Further, the four sub-controllers 105a-1, 105a-2, 105a-3, 105a-4 are connected in order by the communication path 108a, respectively.
The sub-controllers 105a-1 to 105a-4 on each floor are connected to the hall buttons 106a-1 to 106a-4 on each floor.

Up to this point, the configuration is the same as that of FIG. 1 described in the first embodiment, but in the case of the present embodiment, the downstream side of the sub-controller 105a-1 on the first floor is connected by the communication path 107x. It is connected to the Unit 1 main controller 101a.
Therefore, in the configuration of FIG. 16, each sub-controller 105 is connected to the first main controller 101a in a loop by communication paths 107a, 108a, 107x.

The Unit 1 main controller 101a can transmit packets to each sub-controller 105 in order from the upstream side via the communication path 107a, and also transmit packets in order from the downstream side to each sub-controller 105 via the communication path 107x. can do.
Therefore, for example, as shown in FIG. 16, when the sub-controller 105a-3 on the third floor has a communication abnormality, the sub-controller on the fourth floor is set as the terminal communication state packet 601 by the communication from the upstream side via the communication path 107a. Only the controller 105a-4 has a normal value of "1".
Further, in the communication from the downstream side via the communication path 107x, the sub-controllers 105a-1 and 105a-24 on the first floor and the second floor have normal values "1".

Then, the Unit 1 main controller 101a combines the packet from the communication from the upstream side and the packet from the communication from the downstream side so that only the sub-controller 105a-3 on the third floor of the communication abnormality location can be determined to be abnormal. become. That is, as a communication map, the range in which normal communication can be performed by packets from the upstream side and the range in which normal communication can be performed by packets from the downstream side are registered. You will be able to properly identify the location.
When the occurrence of the abnormal portion is determined in this way, the Unit 1 main controller 101a sets the degenerate mode. The operation process when the degenerate mode is set is the same as the process described in the first embodiment.
In this way, even if only one elevator is installed, the effect is the same as that of the two elevators described in the first embodiment. Can be done.

<Example of the third embodiment>
Next, an example of the third embodiment of the present invention will be described with reference to FIG. In FIG. 17, as in the second embodiment, the same reference numerals are given to the same parts as those in FIGS. 1 to 15 of the first embodiment described above, and duplicate description is omitted. ..

An example of the third embodiment of the present invention is the case of an elevator composed of three or more units.
That is, in the embodiment of the present embodiment, in addition to the first main controller 101a and the second main controller 101b described with reference to FIG. 1, the third main controller 101c is provided, and the respective main controllers 101a, 101b, 101c are provided. Is connected by the communication path 112.
In the case of an elevator equipped with four or more elevators, another unit main controller 101 is further connected to the subsequent stage of the third unit main controller 101c via another communication path 112.

Then, regarding the point that the sub-controllers 105a-1 to 105a-4 of the first unit and the sub-controllers 105b-1 to 105b-4 of the second unit are connected in a loop by the communication paths 107a, 108a, 109a, 108b, 107b. Is the same as that of the first embodiment. The communication path 109a shown in FIG. 17 connects the sub-controller 105a-1 on the first floor of Unit 1 and the sub-controller 105b-1 on the first floor of Unit 2, and is the same as the communication path 109 shown in FIG. be.
In the case of the example of FIG. 17, the number of floors is an example.

Here, the Unit 3 main controller 101c is connected to the Unit 3 sub-controllers 105c-1 to 105c-4 in order from the upstream side by communication paths 107c and 108c. Then, the downstream side of the sub-controller 105c-1 on the first floor of Unit 3 is connected to the sub-controller 105b-1 on the first floor of Unit 2 by the communication path 109b.
The second transmission / reception unit 302 (FIG. 4) of the sub-controller 105b-1 on the first floor of Unit 2 is configured to include two communication ports to which a plurality of communication paths 109a and 109b can be connected. Alternatively, the sub-controller 105b-1 on the first floor may be configured to include a third transmission / reception unit in addition to the second transmission / reception unit 302.

Further, in the case of an elevator equipped with four or more elevators, the sub-controller 105c-1 on the first floor of Unit 3 is further connected to the sub-controller 105 on the first floor of another unit.
In this way, even when three or more elevators are installed, the effect is the same as that of the two elevators described in the first embodiment. Can be done.
