FIG. 5 is a flowchart showing an example of the processing operation of the agent device of the variable function remote monitoring system according to the embodiment of the present invention. Here, it is assumed that the abnormality occurrence source is the first elevator A.

First, when an abnormality occurs in the operation of the elevator A, the elevator control device 1 transmits an abnormality notification signal indicating this to the remote monitoring terminal device 2 and the agent device 3.
When receiving the abnormality notification signal from the elevator control device 1, the remote monitoring terminal device 2 outputs this to the center device 5 via the communication line network 4.

  Further, when the communication interface 33 of the agent device 3 receives the abnormality notification signal from the elevator control device 1 (YES in step S1), the abnormality type determination unit 35 generates a signal based on the information included in the abnormality notification signal. The abnormality type of the transmission source elevator A is determined (step S2).

  Then, the search control unit 36 reads the identification information of the first elevator A that is the installation destination from the storage device 32 in order to select another elevator that transmits the control information to the center device 5, and based on this identification information Then, a control signal indicating a search request for identification information of other elevators in the same group is transmitted to the server device 6 via the communication interface 34 and the remote monitoring terminal device 2. That is, the search control unit 36 functions as an identification information requesting unit that requests the server device 6 to transmit identification information of another elevator control device in the same group as the group to which the elevator belongs.

  When receiving the search request control signal from the agent device 3, the server device 6 searches the group management table for the identification information of each elevator excluding the transmission source in the group to which the identification information of the transmission source elevator belongs. Is transmitted to the remote monitoring terminal device 2 of the elevator as the request source via the communication line network 4.

  When receiving the identification information from the server device 6, the remote monitoring terminal device 2 transmits it to the agent device 3. When the communication interface 34 of the agent device 3 receives the identification information, the search control unit 36 stores this information in the storage device 32. This completes the selection of the control information transmission request target (step S3).

  And the transmission request control part 37 reads the identification information memorize | stored in the memory | storage device 32, The abnormality classification which the abnormality classification determination part 35 determined by the process of step S2 among the control information of the elevator corresponding to this identification information A control signal indicating a transmission request for control information related to is transmitted to the remote monitoring terminal device 2 via the communication interface 34. The remote monitoring terminal device 2 transmits a control signal from the transmission control unit 39 to the remote monitoring terminal device of the elevator corresponding to the identification information via the communication line network 4 (step S4). Here, it is assumed that the transmission request destination elevator is the second elevator B.

  An example of transmission request target control information will be described. For example, when the type of abnormality determined by the abnormality type determination unit 35 is the stop of the hoist, the control information that is the target of the transmission request includes the setting value and the rotational speed related to the drive of the hoist. If it is measurement information and the determined abnormality type is stop of the air conditioner, the control information to be transmitted is measurement information such as a set value and circuit voltage related to the operation of the air conditioner.

  When receiving the transmission request control signal from the first elevator A, the remote monitoring terminal device 12 of the second elevator B transmits it to the agent device 13. When the communication interface 34 of the agent device 13 receives the control signal from the remote monitoring terminal device 12 (YES in step S5), the control information acquisition unit 38 receives a control signal indicating an instruction to transmit control information related to the second elevator B. The data is output to the elevator control device 11 via the communication interface 33.

  In accordance with the input of the control signal from the control information acquisition unit 38, the elevator control device 11 sends the control information related to the type of abnormality that has been determined as described above from the control information stored in the internal memory. Output to. This control information includes identification information of the second elevator B.

  When the communication interface 33 of the agent device 13 inputs control information from the elevator control device 11 (step S6), the transmission control unit 39 transmits this control information to the remote monitoring terminal device 12 via the communication interface 34. The remote monitoring terminal device 12 transmits the control information from the transmission control unit 39 to the center device 5 via the communication line network 4 (step S7).

When the communication interface 53 of the center device 5 receives the control information from the second elevator B, the control unit 51 stores this information in the storage device 52.
When a predetermined operation is performed on the input device 54 of the center device 5 in a state where the control information of each elevator belonging to the same group is stored in the storage device 52, the control unit 51 displays the control information regarding each elevator. It is displayed on the device 55.

  The operator of the center device 5 refers to the displayed control information to determine whether or not there is an elevator that may cause an abnormality in the future among the elevators that do not have an abnormality at present. It becomes possible to discriminate. For example, if the measured value of the hoist indicated by the control information has changed to a value close to the limit value for maintaining safety, it is determined that the setting value needs to be changed or repaired.

  As described above, in the variable function remote monitoring system according to the embodiment of the present invention, when an abnormality occurs in any of the plurality of elevators, the agent apparatus that is the source of the abnormality causes the center device 5 to The elevator agent device that has received this request acquires control information related to the installation-source elevator control device and transmits the control information to the center device 5, so that the center device 5 has a minimum load. Thus, the control information of each elevator can be acquired, and by this acquisition, it is possible to prevent the occurrence of abnormality in other elevators.

  In addition, since this system issues a control information transmission request only to an elevator belonging to the same group as the elevator in which the abnormality notification signal is generated, the communication line network 4 and the center device 5 are involved in transmission / reception of control information to the center device 5. The load is reduced, and the efficiency for determining an elevator that may cause an abnormality is improved.

  Further, since this system narrows down the control information to be transmitted to other elevators according to the type of abnormality indicated by the abnormality notification signal, the load on the transmission processing of the control information from each elevator side to the center device 5 is reduced. Thus, it is possible to more efficiently determine an elevator that is smaller and may have an abnormality.
