A detailed description is given below with reference to the drawings. Duplicate descriptions are appropriately simplified or omitted. In each figure, the same reference numerals denote the same or corresponding parts.

Embodiment 1.
FIG. 1 is a diagram showing an example of an elevator system 1 according to Embodiment 1. FIG. FIG. 1 shows an example in which an elevator system 1 comprises four elevator devices. For example, the elevator system 1 includes F, G, H, and I elevators as elevator devices. The number of elevator devices included in the elevator system 1 is not limited to four. For example, elevator system 1 may comprise eight elevator devices.

The elevator system 1 includes a group management board 2, control boards 3F to 3I, a hall operating panel 4FG, a hall operating panel 4HI, a hall light 5, a hall button 6FG, a hall button 6HI, a relay board 7F, a relay board 7H, and a common board 8. Prepare. Furthermore, elevator system 1 comprises network 21 , networks 22 F and 22 H, networks 23 F and 23 H, and network 24 .

The group management board 2 manages operation of the entire system. The group management board 2 is mounted on the group management board. The control board 3F controls the operation of the F car. For example, the F car is controlled by the control board 3F. The control board 3F is mounted on the control panel of the F machine. The control board 3G controls the operation of the G car. For example, the G car is controlled by the control board 3G. The control board 3G is mounted on the control panel of the G machine.

The control board 3H controls the operation of the H car. For example, the H car is controlled by the control board 3H. The control board 3H is mounted on the control panel of the H machine. The control board 3I controls the operation of the I car. For example, car number I is controlled by control board 3I. The control board 3I is mounted on the control panel of the I machine.

Each of the control boards 3F to 3I has the same group management function as the group management board 2 has. A priority for executing the group management function is set in advance for the group management board 2 and the control boards 3F to 3I. Table 1 shows an example of priority setting.

In the example shown in Table 1, the group management board 2 has the highest priority. The board role with the highest priority is the master (MST). The control board 3F has the second highest priority. The board role with the second highest priority is Backup Master (BKMST). The control board 3H has the third highest priority. The board role with the third highest priority is backup slave (BKSLV). Other control boards have the lowest priority. The board role with the lowest priority is slave (SLV).

Each of the group management board 2 and the control boards 3F to 3I is provided with control parameters for enabling and disabling the group management function. For example, in each of the group management board 2, the control board 3F, and the control board 3H, the group management function is enabled by the control parameters in the initial setting. In each of the control boards 3G and 3I, the group management function is disabled by the control parameters in the initial settings. In the elevator system 1, among the group management board 2 and the control boards 3F to 3I, the group management function is enabled and the board with the highest priority executes the group management function. In the example shown in this embodiment, the group management board 2 basically executes the group management function. When the group management board 2 becomes unable to perform the group management function, the role of the control board 3F is moved up from BKMST to MST, and the control board 3F assumes the group management function.

The network 21 connects the group management board 2 and the control boards 3F to 3I in a ring topology. The network 21 may have a plurality of signal lines corresponding to transmission directions. A physical layer of the network 21 is realized by, for example, a LAN (Local Area Network). In the example shown in FIG. 1, regarding the network 21, the control board 3F is arranged between the group management board 2 and the control board 3G. The control board 3G is arranged between the control board 3F and the control board 3H. The control board 3H is arranged between the control board 3G and the control board 3I. The control board 3I is arranged between the control board 3H and the group management board 2 .

The hall operating panel 4FG is installed in the hall of the elevator. The hall operating panel 4FG has an input device for the user to input the destination floor. The hall operating panel 4FG has a display for displaying information to the user. The hall operating panel 4FG may be provided with a mechanical input device, or may be provided with a touch panel type input device. The network 22F connects the hall operating panel 4FG, the control board 3F, and the group control board 2 in a bus topology.

The hall operating panel 4HI has functions similar to those of the hall operating panel 4FG. The hall operation panel 4HI is installed at the hall of the elevator. The hall operating panel 4HI has an input device for the user to input the destination floor. The hall operating panel 4HI has a display for displaying information to the user. The network 22H connects the hall operating panel 4HI, the control board 3H, and the group management board 2 in a bus topology.

In the following description, the hall operating panel 4FG and the hall operating panel 4HI are referred to as the hall operating panel 4 when there is no need to distinguish them. Similarly, when there is no need to distinguish between the network 22F and the network 22H, the network 22 is used. A physical layer and a data link layer of the network 22 are realized by CAN (Controller Area Network), for example. FIG. 1 shows an example in which the elevator system 1 includes one hall control panel 4 for two elevator devices. The elevator system 1 may include one hall control panel 4 for four elevator devices.

The landing button 6FG is installed at the elevator landing. The hall buttons 6FG include an up button and a down button. The network 23F connects the hall button 6FG to the group management board 2 or the control board 3F via the relay board 7F. The relay board 7F switches the connection destination of the hall button 6FG to the group management board 2 or the control board 3F. The relay board 7F is mounted on the control panel of the F car.

The hall button 6HI has the same function as that of the hall button 6FG. The landing button 6HI is installed at the elevator landing. The landing buttons 6HI include an up button and a down button. The network 23H connects the hall button 6HI to the group management board 2 or the control board 3H via the relay board 7H. The relay board 7H switches the connection destination of the hall button 6HI to the group management board 2 or the control board 3H. The relay board 7H is mounted on the control panel of the H-th machine.

In the following, when there is no need to distinguish between the hall button 6FG and the hall button 6HI, the hall button 6 will be used. Similarly, when there is no need to distinguish between the network 23F and the network 23H, the network 23 is used. A physical layer of the network 23 is realized by cables, for example. FIG. 1 shows an example in which the elevator system 1 has one hall button 6 for two elevator devices. The elevator system 1 may include one hall button 6 for one elevator device.

FIG. 1 shows an example in which an elevator system 1 includes both a hall operating panel 4 and a hall button 6 . The elevator system 1 may include only one of the hall operating panel 4 and the hall button 6 . The hall operating panel 4 is an example of hall equipment that transmits a call registration request. Similarly, hall button 6 is an example of hall equipment that transmits a call registration request.

The common substrate 8 performs input/output processing of common signals. A common signal is a signal required in all elevators included in the elevator system 1 . For example, a building in which the elevator system 1 is provided is provided with a seismic sensor (not shown). A seismic signal output from a seismic sensor is an example of a common signal. A seismic signal output from the seismic sensor is input to the common substrate 8 . As another example, the building in which the elevator system 1 is installed is provided with a fire detector (not shown). A fire signal output from a fire sensor is an example of a common signal. A fire signal output from the fire sensor is input to the common substrate 8 .

The network 24 connects the common substrate 8, the group management substrate 2 and the control substrates 3F to 3I in a bus topology. A physical layer and a data link layer of the network 24 are realized by CAN, for example.

FIG. 2 is a diagram for explaining the functions of the group management board 2. As shown in FIG. The group management board 2 includes a node determination section 31 , an allocation section 32 , a command section 33 , a detachment detection section 34 , an isolation detection section 35 , a transfer section 36 and a return detection section 37 . The functioning of the elevator system 1 will be described in detail below, also with reference to FIGS. 3 to 8. FIG. FIGS. 3 to 8 are flowcharts showing an operation example of the elevator system 1 according to Embodiment 1. FIG. FIG. 3 shows an example of the operation of a board whose role is set to MST. For example, FIG. 3 shows the operation of the group management board 2. As shown in FIG.

The node determination unit 31 transmits an entry request via the network 21 to the control boards 3F to 3I (S101). The entry request is an inquiry to the control board required for group management. For example, in S<b>101 , the group management board 2 broadcasts an entry request to the network 21 . Note that the process of S101 is periodically performed in the group management board 2. FIG.

FIG. 4 shows an operation example of a control board whose role is not set to MST. For example, FIG. 4 shows the operation of each of the control boards 3F-3I. For example, the control board 3G determines whether or not an entry request has been received via the network 21 (S201). When the control board 3G receives the entry request transmitted by the node determination unit 31 in S101, it is determined as Yes in S201. When the control board 3G determines Yes in S201, it transmits an entry response to the group control board 2 via the network 21 (S202).

After transmitting the entry request in S101, the node determination unit 31 determines whether or not entry responses have been received from all of the control boards 3F to 3I via the network 21 (S102). When the group management board 2 receives entry responses from all of the control boards 3F to 3I, it is determined as Yes in S102.

If it is not determined as Yes in S108, it is determined as No in S103. The processing of S108 will be described later. When determined as No in S103, the node determination unit 31 transmits a signal indicating the role via the network 21 to each of the control boards that have transmitted the entry response (S105). Hereinafter, the signal indicating the role is also referred to as "role signal". In the example shown in Table 1, the node determination unit 31 transmits a role signal indicating BKMST to the control board 3F in S105. The node determination unit 31 transmits a role signal indicating SLV to the control board 3G in S105.

In the control board 3G that has transmitted the entry response to the group management board 2 in S202, it is determined whether or not the role signal has been received (S203). When the control board 3G receives the role signal transmitted by the node determination unit 31 in S105, it is determined as Yes in S203. The control board 3G sets the role of its own according to the role signal received in S203 (S204).

In the group management board 2, when the determination in S102 is Yes, normal allocation control is performed (S106). FIG. 5 shows an example of normal allocation control. In the group control board 2, it is determined whether or not a call registration request has been received from the hall operating panel 4 (S301). For example, in S<b>301 , a permission signal for permitting signal transmission is periodically broadcast from the group management board 2 to the network 22 .

FIG. 6 shows an operation example of the hall operating panel 4 . A user of the elevator can input a destination floor by performing a specific input operation on the hall operating panel 4 . At the hall operating panel 4, it is determined whether or not an input operation has been performed (S401). When the user inputs the destination floor from the hall operating panel 4, it is determined as Yes in S401. If it is determined as Yes in S401, the hall control panel 4 determines whether or not a permission signal has been received (S402).

When the hall operating panel 4 receives the permission signal transmitted by the group control board 2 in S301, it is determined as Yes in S402. When the hall operating panel 4 determines Yes in S402, it transmits a call registration request via the network 22 to the group control board 2 that has transmitted the permission signal (S403). The registration request transmitted by the hall operating panel 4 includes information on the destination floor.

When the group control board 2 receives the registration request transmitted by the hall control panel 4 in S403, it is determined as Yes in S301. When the allocation unit 32 determines Yes in S301, it determines the allocation car for the registration request received in S301 (S302).

The group management board 2 has received the entry response in S102. Therefore, in the group management board 2, control boards that can communicate via the network 21 are specified. In S<b>302 , the assignment unit 32 determines an assigned car from among the cars controlled by the control board that can communicate via the network 21 . If the determination in S102 is Yes, the allocation unit 32 determines the allocated car from among the four cars controlled by the control boards 3F to 3I.

The command unit 33 transmits a response command via the network 21 to the control board that controls the assigned car determined by the assignment unit 32 (S303). For example, if the car of car G is the assigned car, the command unit 33 transmits a response command to the control board 3G via the network 21 . Information on the destination floor is included in the response command transmitted in S303. Further, when the allocation unit 32 determines the allocated car, the command unit 33 transmits a response signal via the network 22 to the hall operating panel 4 that has transmitted the registration request in S301 (S304). The response signal sent to the hall operating panel 4 in S304 includes information on the assigned car.

In the hall operating panel 4, when the registration request is transmitted in S403, it is determined whether or not a response signal has been received (S404). When the hall operating panel 4 receives the response signal transmitted by the command unit 33 in S304, it is determined as Yes in S404. If it is determined as Yes in S404, information on the assigned car is displayed on the display device in the hall operating panel 4 based on the received response signal (S405). The user can know the assigned car by looking at the display of the hall operating panel 4. - 特許庁

The control board 3G determines whether or not a response command has been received via the network 21 (S205 in FIG. 4). When the control board 3G receives the response command transmitted by the command unit 33 in S303, it is determined as Yes in S205. If it is determined as Yes in S205, response control for carrying the user to the destination floor is performed in the control board 3G (S206). As a result, the user can move to the destination floor in the car of the G car, which is the assigned car.

Also, in the group control board 2, it is determined whether or not a call registration request has been received from the hall button 6 in normal allocation control (S305 in FIG. 5). When the user presses the hall button 6 , a call registration request is transmitted from the hall button 6 to the group control board 2 via the network 23 . When the group control board 2 receives the registration request transmitted from the hall button 6, it is determined as Yes in S305. When the allocation unit 32 determines Yes in S305, it determines the allocation car for the registration request received in S305 (S306).

In S306, the allocation unit 32 determines an allocation car from among the cars controlled by the control board that can communicate via the network 21. FIG. If the determination in S102 is Yes, the allocation unit 32 determines the allocated car from among the four cars controlled by the control boards 3F to 3I.

The command unit 33 transmits a response command via the network 21 to the control board that controls the assigned car determined by the assignment unit 32 (S307). For example, if the car of car G is the assigned car, the command unit 33 transmits a response command to the control board 3G via the network 21 . Information on the destination floor is not included in the response command transmitted in S307. Further, when the allocation unit 32 determines the allocated car, the command unit 33 transmits a response signal via the network 23 to the hall button 6 that has transmitted the registration request in S305 (S308).

In hall button 6, the internal lamp lights up in response to the response signal transmitted in S308. The user can know that the call has been registered by looking at the lighted hall button 6. - 特許庁

Also, when the control board 3G receives the response command sent by the command unit 33 in S307, it is determined as Yes in S205 of FIG. If it is determined as Yes in S205, the control board 3G performs response control for moving the car to the hall where the user is (S206). As a result, the user can get on the car of the G car, which is the assigned car.

Next, an example in which the determination in S102 is No will be described. For example, when maintenance is performed on the F machine, the power supply of the control panel of the F machine may be turned off. When the power of the control panel of the F machine is turned off, the control board 3F cannot perform the operation shown in FIG. Therefore, even if the group management board 2 transmits the entry request in S101, the control board 3F does not transmit the entry response to the group management board 2. FIG. In S102, it is determined as No.

When determined as No in S102, the detachment detection unit 34 detects the detachment board based on the received entry response (S107). A disconnected board is a control board that cannot communicate via the network 21 among the control boards 3F to 3I. Even if the F car is being maintained, each of the control boards 3G to 3I transmits an entry response to the group management board 2. FIG. Therefore, when the maintenance of the F machine is started, the detachment detection unit 34 detects the control board 3F as the detachment board in S107.

Further, when it is determined No in S102, the isolation detection unit 35 determines whether or not there is an isolation board based on the received entry response (S108). The isolation board is a control board that cannot communicate via the network 21 even though the communication function is not stopped among the control boards 3F to 3I. As an example, if there is only one control board that has not transmitted an entry response, the isolation detection unit 35 determines No in S108. If determined as No in S108, the process proceeds to S103. In such a case, the group management board 2 performs normal allocation control after excluding the detached board from the control targets.

Next, an example in which it is determined as Yes in S108 will be described. Consider an example in which maintenance of F-type machine and H-type machine are performed at the same time. When the H machine is maintained, the power of the control panel of the H machine may be turned off. For this reason, when the maintenance of the F car and the maintenance of the H car are performed at the same time, even if the group control board 2 transmits the entry request in S101, the control board 3F does not transmit the entry response to the group control board 2. . Similarly, no entry response is sent from the control board 3H to the group management board 2. FIG. The detachment detection unit 34 detects the control board 3F and the control board 3H as the detachment board in S107.

The control board 3G is arranged between the control board 3F and the control board 3H. Therefore, when the control board 3</b>F and the control board 3</b>H are disconnected from the network 21 , the control board 3</b>G is also disconnected from the network 21 . The control board 3G cannot receive the entry request sent by the group management board 2 in S101. Therefore, the control board 3G does not transmit an entry response. The detachment detection unit 34 detects the control board 3G as the detachment board in S107. Although the control board 3G cannot communicate via the network 21, its communication function is not stopped.

The isolation detection unit 35 detects, for example, a substrate in which both adjacent substrates are detached substrates as an isolated substrate. When the maintenance of the F machine and the maintenance of the H machine are performed at the same time, the control board 3G is arranged between the control board 3F which is the detachable board and the control board 3H which is the detachable board. Therefore, in S108, the isolation detection unit 35 detects that the control board 3G is isolated from the network 21, that is, the presence of the isolated board.

When S108 determines Yes, the node determination unit 31 transmits a role signal via the network 21 to each of the control boards 3F to 3I that has transmitted the entry response (S109). Further, when it is determined as Yes in S108, special allocation control is started in the group control board 2 (S110).

FIG. 7 shows an example of special allocation control. In the group control board 2, it is determined whether or not a call registration request has been received from the hall operating panel 4FG (S501). For example, in S501, a permission signal for permitting signal transmission is periodically broadcast from the group management board 2 to the network 22F. Further, in the group control board 2, it is determined whether or not a call registration request has been received from the hall operating panel 4HI (S502). For example, in S502, a permission signal for permitting signal transmission is periodically broadcast from the group management board 2 to the network 22H. The operation shown in FIG. 6 is performed on each of the hall operating panel 4FG and the hall operating panel 4HI.

When the group control board 2 receives the registration request transmitted by the hall operating panel 4HI in S403, it is determined as Yes in S502. The operations from S503 to S505 are the same as the operations from S302 to S304. When the assigning unit 32 determines Yes in S502, it determines an assigned car from among the cars controlled by the control board that can communicate via the network 21 (S503).

The command unit 33 transmits a response command via the network 21 to the control board that controls the assigned car determined by the assignment unit 32 (S504). Further, when the allocation unit 32 determines the allocated car, the command unit 33 transmits a response signal via the network 22H to the hall operating panel 4HI that transmitted the registration request in S502 (S505). The response signal sent to the hall operating panel 4HI in S505 includes information on the assigned car.

On the other hand, when the group control board 2 receives the registration request transmitted by the hall operating panel 4FG in S403, it is determined as Yes in S501. The allocation unit 32 does not determine the allocation car for the registration request even if it is determined as Yes in S501. If determined as Yes in S501, the transfer unit 36 transfers the registration request from the hall operating panel 4FG to the isolation board, ie, the control board 3G via the network 24 (S506). In S506, the transfer unit 36 sends the registration request received in S501 to the control board 3G as it is.

For example, the control board 3G determines whether or not the registration request from the hall operating panel 4FG is received from the group control board 2 via the network 24 (S207). When the control board 3G receives the registration request transferred by the transfer unit 36 in S506, a determination of Yes is made in S207. When it is determined as Yes in S207, the control board 3G transmits a response signal to the received registration request to the group management board 2 via the network 24 (S208). The response signal transmitted in S208 includes information on the number of machines responding to the registration request. Further, when it is determined as Yes in S207, response control for carrying the user to the destination floor is performed in the control board 3G (S209).

After transferring the registration request in S506, the transfer unit 36 determines whether or not a response signal is received via the network 24 from the control board 3G to which the registration request is transferred (S507). When the group management board 2 receives the response signal transmitted by the control board 3G in S208, it is determined as Yes in S507. When the transfer unit 36 determines Yes in S507, the transfer unit 36 transfers the response signal from the control board 3G to the hall operating panel 4FG via the network 22F (S508). In S508, the transfer unit 36 sends the response signal received in S507 to the hall operating panel 4FG as it is.

FIG. 8 shows another example of special allocation control. FIG. 7 shows the operation of the group control board 2 when a registration request is received from the hall operating panel 4 . On the other hand, FIG. 8 shows the operation of the group control board 2 when a registration request is received from the hall button 6. As shown in FIG.

In the group control board 2, it is determined whether or not a call registration request has been received from the hall button 6FG (S601). Further, in the group control board 2, it is determined whether or not a call registration request has been received from the hall button 6HI (S602). When the user presses the hall button 6HI, a call registration request is transmitted from the hall button 6HI to the group control board 2 via the network 23H. When the group control board 2 receives the registration request transmitted from the hall button 6HI, it is determined as Yes in S602.

The operations from S603 to S605 are the same as the operations from S306 to S308. When the assigning unit 32 determines Yes in S602, it determines an assigned car from among the cars controlled by the control board that can communicate via the network 21 (S603). The command unit 33 transmits a response command via the network 21 to the control board that controls the assigned car determined by the assignment unit 32 (S604). Further, when the allocation unit 32 determines the allocated car, the command unit 33 transmits a response signal via the network 23H to the hall button 6HI that transmitted the registration request in S602 (S605).

When the user presses the hall button 6FG, it is determined as Yes in S601. The allocation unit 32 does not determine the allocation car for the registration request even if it is determined as Yes in S601. If it is determined as Yes in S601, the transfer section 36 transfers the registration request from the hall button 6FG to the isolation board, that is, the control board 3G via the network 24 (S606). In S606, the transfer unit 36 sends the registration request received in S601 to the control board 3G as it is.

For example, the control board 3G determines whether or not the registration request from the hall button 6FG is received from the group control board 2 via the network 24 (S210). When the control board 3G receives the registration request transferred by the transfer unit 36 in S606, a determination of Yes is made in S210. If determined as Yes in S210, the control board 3G transmits a response signal to the received registration request to the group management board 2 via the network 24 (S211). Further, when it is determined as Yes in S210, the control board 3G performs response control for moving the car to the hall where the user is located (S212).

After transferring the registration request in S606, the transfer unit 36 determines whether or not a response signal has been received via the network 24 from the control board 3G to which the registration request is transferred (S607). When the group management board 2 receives the response signal transmitted by the control board 3G in S211, it is determined as Yes in S607. When the transfer unit 36 determines Yes in S607, it transfers the response signal from the control board 3G to the hall button 6FG via the network 23F (S608). In S608, the transfer unit 36 sends the response signal received in S607 to the hall button 6FG as it is.

Next, an example will be described in which, after a Yes determination is made in S108, a No determination is made in S108 or a Yes determination is made in S102. As described above, when the maintenance of the F-type machine and the maintenance of the H-type machine are performed at the same time, it is determined as Yes in S108. After that, when the maintenance of the F machine and the maintenance of the H machine are finished, the operation shown in FIG. 4 is started in the control board 3F and the control board 3H. Further, the control board 3G can communicate with the group management board 2 via the network 21. FIG.

The return detection unit 37 determines whether or not the isolated board has returned to the network 21 in S103. For example, when the return detection unit 37 receives the entry response from the control board detected as the isolated board in S108, it detects that the control board has returned to the network 21 (Yes in S103). If determined as Yes in S103, the transfer unit 36 stops transferring the registration request in S506 and S606 (S104). As a result, normal allocation control is resumed in S106.

In the example shown in this embodiment, for example, even if the control board 3G is isolated from the network 21, the registration request from the hall operating panel 4FG is transferred from the group control board 2 to the control board 3G. Therefore, even if the control board 3G is isolated from the network 21, it is possible to prevent the operation efficiency from significantly deteriorating.

Further, when the control board 3G returns to the network 21, the transfer of the registration request is stopped. Therefore, the normal allocation control can be resumed immediately when the isolated board returns to the network 21 .

Transfer of the registration request by the transfer unit 36 is performed via the network 24 . Network 24 is basically a network used for the transmission of common signals. For example, when receiving an earthquake signal from an earthquake sensor, the common board 8 transmits the received earthquake signal to the group management board 2 via the network 24 . At this time, an earthquake signal may be broadcast from the common board 8 to the network 24 . As another example, when the common board 8 receives a fire signal from a fire sensor, it transmits the received fire signal to the group management board 2 via the network 24 . At this time, a fire signal may be broadcast from the common board 8 to the network 24 .

FIG. 9 is a flow chart showing another operation example of the elevator system 1 according to the first embodiment. FIG. 9 shows another operation of the control board whose role is not set to MST. Another example in which the isolation detection unit 35 detects the isolation substrate will be described below with reference to FIG. The processing from S201 to S212 in FIG. 9 is the same as the processing from S201 to S212 in FIG.

As described above, the entry request is periodically transmitted from the group management board 2 to the control boards 3F to 3I via the network 21. FIG. For example, the control board 3G determines whether or not an entry request has been received (S201). When the control board 3G determines Yes in S201, it performs the processes shown in S202 to S206 described above.

When it is determined as No in S201, the control board 3G determines whether or not the time T has passed without receiving the entry request (S213). The time T is longer than the period of transmission of the entry request by the group management board 2 . If the control board 3G does not receive the entry request from the group management board 2 until the time T elapses, it transmits an isolation signal to the group management board 2 via the network 24 (S214). In S214, an isolation signal may be broadcast to the network 24 from the control board 3G.

When receiving the isolation signal transmitted in S<b>214 , the isolation detection unit 35 detects that the control board transmitting the isolation signal is isolated from the network 21 . The isolation detection unit 35 may detect that the control board that has transmitted the isolation signal is isolated from the network 21 when the isolation signal is received from a board whose adjacent boards are both detached boards.
