In addition to the group management unit 200, the low-rise section 20 has operation control units 41 to 43 that control the operation of the elevator cars 25 to 27 of the hoistway groups 21 in addition to the group management unit 200. Yes.

  Hereinafter, the configuration of the group management unit 300 will be described. Since the configuration of the group management unit 200 is the same as that of the group management unit 300, the description of the configuration of the group management unit 200 is omitted. The group management unit 300 includes a group management control unit 361 that performs overall control of operations of the plurality of cars 35 to 37 and a learning process for shortening the waiting time of the cars 35 to 37, and the operation control units 51 to 51. A communication control unit 310 that executes communication control between the first communication path 101 and the other group management unit 200 connected to the second communication path 102; ,have.

  The communication control unit 310 includes a first communication port 321 connected to the first communication path 101, a second communication port 322 connected to the second communication path 102, and the first communication port 321. A first data transmission / reception unit 330 that transmits / receives data, a second data transmission / reception unit 340 that transmits / receives data via the second communication port 322, a group management control unit 361, and a first data transmission / reception unit. 330 and the second data transmission / reception unit 340, and compares the communication data received by both the first data transmission / reception unit 330 and the second data transmission / reception unit 340 and stores them in its own buffer. The received data comparison unit 353 is connected to the group management control unit 361, the first data transmission / reception unit 330, and the second data transmission / reception unit 340, and is handled by the group management control unit 361 and the like. The transmission data division unit 352 for transferring the data stored in the buffer to both the first data transmission / reception unit 330 and the second data transmission / reception unit 340, the group management control unit 361, and the first The first data transmission / reception unit 330 and the second data transmission / reception unit 340 are connected to each other, interrupted during communication of other communication data, and either or both of the first communication path 101 and the second communication path 102 And an interrupt transmission control unit 351 that transmits the data. Here, the group management unit 200 includes a motor control unit and a car control unit in addition to this, but a description thereof is omitted here.

  In this embodiment, the control system 100 is constituted by the two group management units of the group management unit 200 and the group management unit 300. However, the present invention is not limited to two, but three or more group management units are connected. It may be a thing. Furthermore, the present invention is not limited to the group management unit of the elevator apparatus, but may be anything that connects a plurality of control units through at least the first communication path and the second communication path. Here, the first communication path 101 and the second communication path 102 may be a full-duplex connection or a half-duplex connection as long as transmission and reception are possible. Moreover, although the group management unit 300 is described as having the communication control unit 310, the group management control unit 361, and the operation communication unit 362, it may not have these, the first communication path and What is necessary is just to communicate using a 2nd communication path.

(2) Communication Data Processed by Communication Control Unit Next, communication data processed by the communication control unit 310 will be described. The first communication path 101 and the second communication path 102 are used for communication of at least the first communication data D1, the second communication data D2, the third communication data D3, and the fourth communication data D4. For example, the first communication data D1 is required to have the highest responsiveness and the highest reliability. However, since the amount of communication data is small, it can be data that does not require a network transmission capacity. For example, in the present embodiment, the first communication data D1 is accurate between emergency data such as failure information and alarm information, and group management control units 361 of a plurality of group management units 300 connected via a network. Synchronization control data for performing processing with time synchronization can be used as communication data.

  Further, the second communication data D2 is not required to be responsive, but is required to have high reliability, and data that requires a large transmission capacity of the network as the number of communication targets such as the group management unit 300 increases. can do. For example, in the present embodiment, the second communication data D2 is used for overall control of the operation control units 51 to 53 by the group management unit 300 and operation control of the cars 35 to 37 of the operation control units 51 to 53. The setting data can be used as communication data. The second communication data D2 can be data that is periodically communicated.

  The third communication data D3 is required to have high responsiveness. However, since the data is constantly updated, reliability for one communication is not required, and an increase in communication targets such as the group management unit 300 or the entire system As control performance improves and functions are expanded, data that requires a large network transmission capacity can be obtained. For example, in the present embodiment, the third communication data D3 is used for the overall control of the operation control units 51 to 53 by the group management unit 300 and the operation control itself of the cars 35 to 37 of the operation control units 51 to 53. The control data that is constantly updated in a short cycle during system operation can be used as communication data. The third communication data D3 can be data that is periodically communicated.

  The fourth communication data D4 may be less responsive and reliable than other communication data. However, since the communication data amount is large, the fourth communication data D4 can be the data that requires the largest amount of network transmission. . For example, in the present embodiment, the fourth communication data D4 includes learning data for overall control of the group management unit 300, image data to be displayed on the boarding floor, and monitors in the cars 35 to 37, etc. Can be data to be communicated. The contents of each communication data have been illustrated above, but the first communication data D1 to the fourth communication data D4 can be appropriately determined according to the required communication performance.

(3) Control by Communication Control Unit FIG. 3 is a timing chart showing communication performed by the group management unit 300 using the first communication path 101 and the second communication path 102 to the group management unit 200. . Here, the communication is described as an example of communication between the group management unit 300 and the group management unit 200. However, communication may be performed between the group management unit 300 and the group management unit 200, and a communication word may be received as well as transmitted. Is also used to mean. As shown in this timing chart, when the data update event E1 occurs at time T1, the communication control unit 310 performs communication of the first communication data D1 with the first communication path 101 and the second communication. This is performed using both of the paths 102. Here, the first communication data D1 is transferred to both the first data transmitting / receiving unit 330 and the second data transmitting / receiving unit 340 by the transmission data dividing unit 352, and the first data transmitting / receiving unit 330 and the second data are transmitted. The transmission / reception unit 340 transmits the first communication data D1 from the first communication port 321 and the second communication port 322 via the first communication path 101 and the second communication path 102, respectively.

  Next, the process at the time of receiving the first communication data D1 will be described by taking as an example a case where the group management unit 300 receives the first communication data D1 via the first communication path 101 and the second communication path 102. The first communication data D1 received by the first data transmission / reception unit 330 and the second data transmission / reception unit 340 via the first communication port 321 and the second communication port 322 of the communication control unit 310 is received data. The data is transferred to the comparison unit 353, and the reception data comparison unit 353 checks whether or not the first communication data D1 received by the first data transmission / reception unit 330 and the second data transmission / reception unit 340 match.

  In addition, the communication control unit 310 performs communication of the second communication data D2 using both the first communication path 101 and the second communication path 102. Here, the second communication data D2 is transferred to both the first data transmitting / receiving unit 330 and the second data transmitting / receiving unit 340 by the transmission data dividing unit 352, and the first data transmitting / receiving unit 330 and the second data are transmitted. The transmission / reception unit 340 transmits the second communication data D2 from the first communication port 321 and the second communication port 322 via the first communication path 101 and the second communication path 102, respectively. Here, the communication control unit 310 transmits the second communication data D2 in the cycle TI2.

  As in the case of the first communication data D1, for example, if the second communication data D2 is received by the group management unit 300, the first data transmission / reception unit 330 and the second data transmission / reception of the communication control unit 310 The second communication data D2 received by the unit 340 is transferred to the reception data comparison unit 353, and the reception data comparison unit 353 receives the first data transmission / reception unit 330 and the second data transmission / reception unit 340. It is confirmed whether the communication data D1 of 1 matches.

  In addition, the communication control unit 310 performs communication of the third communication data D3 using the first communication path 101. The third communication data D3 is transferred to the first data transmission / reception unit 330. The first data transmission / reception unit 330 receives the third communication data from the first communication port 321 via the first communication path 101. D3 is transmitted. Here, the communication control unit 310 transmits the third communication data D3 in the cycle TI3.

  Further, as shown at time T <b> 2 in FIG. 3, the communication control unit 310 performs communication of the fourth communication data D <b> 4 using the second communication path 102 when the data update event E <b> 4 occurs. Here, the fourth communication data D4 is transferred to the second data transmission / reception unit 340, and the second data transmission / reception unit 340 transmits the fourth communication data from the second communication port 322 via the second communication path 102. Data D4 is transmitted. At this time, when the communication time of the fourth communication data D4 exceeds the communication interval TI22 of the second communication data D2 communicated periodically, the communication control unit 310 sets the communication time equal to or shorter than the communication interval TI22. The four communication data D4 may be divided and transmitted. Further, even when the event D4 occurs during the communication of the second communication data D2, the communication of the second communication data D2 is continued, and after the communication of the second communication data D2 is completed, the fourth communication data D4. Communication starts.

  Here, a process when the event E1 occurs during communication of the third communication data D3 or communication of the fourth communication data D4 will be described. As shown at time T3 in FIG. 3, when the event E1 occurs during the communication of the third communication data D3 or the communication of the fourth communication data D4, the communication control unit 310 performs the third communication. The communication of the data D3 and the fourth communication data D4 is interrupted, and the communication of the first communication data D1 is prioritized. Specifically, the interrupt transmission control unit 351 instructs the first data transmission / reception unit 330 and the second data transmission / reception unit 340 to transmit the transfer interruption data DS, and the first data transmission / reception unit 330. The second data transmitting / receiving unit 340 transmits the transfer interruption data DS via the first communication port 321 and the second communication port 322, and the first communication channel 101 and the second communication channel 102, respectively. . After the transmission interruption data DS is transmitted, the first communication data D1 is transmitted via the first communication path 101 and the second communication path 102, and the transmission is interrupted after the transmission of the first communication data D1 is completed. The communication of the third communication data D3 and the fourth communication data D4 is transmitted from the beginning. At this time, when the time TI23 until the start of communication of the next second communication data D2 exceeds the communication time of the third communication data D3, or exceeds the communication time of the fourth communication data D4, The third communication data D3 or the fourth communication data D4 may be divided and transmitted in units that end with the communication time of the time TI23 ("periodic divided data" described later).

  Although the case where the event E1 occurs at the timing during the communication of the third communication data D3 and the fourth communication data D4 has been described, the case where the event E1 occurs at the timing during the communication of the second communication data D2 is also described. Through similar processing, the communication of the first communication data D1 can be prioritized. Here, the fourth communication data D4 starts communication by the event E4, but the fourth communication data D4 may also start communication periodically.

  4 and 5 are timing charts showing cases where communication on the second communication path 102 and the first communication path 101 is disabled. As shown in FIG. 4, after the second communication path 102 becomes incapable of communication (time T41), the communication control unit 310 uses only the first communication path 101 to transmit the first communication data D1, The communication of the second communication data D2 and the third communication data D3 is continued, and the communication of the fourth communication data D4 is not performed. As shown in FIG. 5, the communication control unit 310 is transferring the fourth communication data D4 in the second communication path 102 when the first communication path 101 becomes unable to communicate (time T42). In this case, the transfer interruption data DS is transferred via the second communication path 102 to interrupt the communication, and only the second communication path 102 is used to transmit the first communication data D1 and the second communication data. The communication of D2 and the third communication data D3 is continued, and the communication of the fourth communication data D4 is not performed.

(4) Effects of this embodiment Conventionally, abnormalities such as inability to communicate have occurred on the communication path, and the control performance of the connecting control of the cars 25 to 27 and 35 to 37 is lowered, and the elevator system is degenerated. There was a risk of controlling at the expense of efficiency. According to the present embodiment, even if an abnormality occurs in one of the first communication path 101 and the second communication path 102 and communication becomes impossible, the first communication data that is more necessary information Since the communication is narrowed down to D1, the second communication data D2, and the third communication data D3, it is possible to suppress the deterioration of the communication performance of the transfer using only one communication path, and the transfer of the cars 25 to 27 and 35 to 37 The control performance of the control can be maintained. Therefore, even when some of the plurality of communication paths become unusable, communication between the plurality of control devices can be performed more efficiently.

  In the present embodiment, since the communication path can be used efficiently, the communication capacity of the network can be improved. For this reason, for example, in the movement between the high-rise section 30 and the low-rise section 20 using the plurality of group management units 300, the efficiency of the transfer of the cars 25 to 27 and 35 to 37, and the plurality of group management units It is possible to improve the control performance such as shortening the waiting time in the assignment control of the cars 25 to 27 and 35 to 37 sharing the learning data. Further, it is possible to realize the function expansion of the group management unit 300 by connecting to an external device such as a wide area network 60, a gate, a sensor, a monitor, or a camera.

  4 and 5, the communication of the fourth communication data D4 is stopped when an abnormality occurs in any of the communication paths, but the communication idle time of the communication path where communication is possible is used. And it is good also as performing communication of the 4th communication data D4. Further, regarding the detection of communication failure on the communication path, it can be detected by notification by alarm information or other known methods in communication protocols.

  In the present embodiment, the communication using the first communication path 101 and the second communication path 102 is applied to the communication between the group management units 200 and 300. However, the group management unit 300 and the operation control unit 51 are used. To 53, communication between the operation control units 51 to 53, and communication related to the motor control unit and the car control unit.

(5) Modification of this Embodiment FIG. 6 is a block diagram showing a group management unit 400 according to a modification of the above-described embodiment, and FIG. It is a timing chart shown about the case where communication of the communication path 101 and the 2nd communication path 102 is performed. The group management unit 400 is different from the group management unit 300 in FIG. 2 in that the communication control unit 410 includes a transmission time management unit 454. The transmission time management unit 454 monitors the remaining transmission time of the fourth communication data D4. As shown in FIG. 7, the second communication data D2 and the third communication data D3 are, for example, m and n permissible time divisions, respectively, so as to be divided time TI21 and divided time TI31. It is divided into data (D2-1 to D2-n, D3-1 to D3-m) and transmitted. Here, the division time TI21 and the division time TI31 are set to the response allowable time TI10 or less, which is the maximum allowable time from when the first communication data D1 is transmitted after the occurrence of the data update event E1. The Further, the fourth communication data D4 is divided into periodic divided data (D4-1, D4-2,...) That are communication units of a divided time TI41 that is a time shorter than the communication interval TI22 of the second communication data D2. To be sent.

  8 and 9 are timing charts showing interrupt control when the group management unit 400 is used. As shown in FIG. 8, assuming that an event E1 occurs during the transmission of the second allowable time division data D3-2 of the third communication data D3 on the first communication path 101, first, the communication control unit 410. The interrupt transmission control unit 351 transmits the first communication data D1 after the transmission of the second allowable time division data D3-2 of the third communication data D3, and transmits the first communication data D1. After the transmission is completed, the transmission is restarted from the third allowable time division data D3-3 of the third communication data D3.

  Also, if this event E1 occurs in the second communication path 102 in the first periodic division data D4-1 of the fourth communication data D4, the transmission time management unit 454 sends the data transmission / reception unit 340 to the data transmission / reception unit 340. , The remaining time TI40 until the transmission of the first periodic divided data D4-1 of the fourth communication data D4 is notified, and the data transmitting / receiving unit 340 determines that the transfer interruption data because the remaining time TI40 is greater than the allowable response time TI10 The DS is transmitted, and then the first communication data D1 is transmitted. When the transmission of the first communication data D1 is completed, the transmission is restarted from the beginning of the first period division data D4-1 of the fourth communication data D4.

  In FIG. 9, the timing at which the event E1 occurs in the first communication path 101 is during the transmission of the second allowable time division data D3-2 of the third communication data D3, as in FIG. Description is omitted. The timing at which the event E1 occurs in the second communication path 102 is generated in the first period division data D4-1 of the fourth communication data D4 as in FIG. 8, but is notified from the transmission time management unit 454. Since the remaining time T140 is smaller than the allowable response time TI10, the data transmitting / receiving unit 340 transmits the first communication data D1 after the transmission of the divided data D-1 is completed. When the transmission of the first communication data D1 is completed, the transmission is restarted from the second period division data D4-2 of the fourth communication data D4.

  8 and 9, the case where the event E1 occurs when the third communication data D3 and the fourth communication data D4 are in communication has been described. However, the second communication data D2 is Even during communication, the same communication control as the third communication data D3 can be used.

  By using the communication control as described above, it is possible to obtain the same effect as that of the embodiment by the configuration of the group management unit 300 in FIG. 2 and to ensure the communication performance such as the responsiveness of the network communication and the communication cycle. Therefore, even when the number of group management units is increased or when external devices such as gates, sensors, monitors, and cameras are added, the control performance that forms the basis of the elevator system such as the connection of the cars 35 to 37 can be achieved. Can be maintained.

  The present invention can be applied to, for example, a system including a plurality of control devices such as an automobile in addition to an elevator device installed in a building or the like.
