Hereinafter, an elevator remote monitoring system according to the present invention will be described with reference to the drawings according to a preferred embodiment. In the description of the drawings, the same portions or corresponding portions are denoted by the same reference numerals, and redundant description is omitted.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram illustrating an elevator remote monitoring system according to Embodiment 1 of the present invention. The elevator remote monitoring system shown in FIG. 1 includes an elevator 2 that is individually provided in a plurality of buildings 1, an information center 3 that is provided remotely and manages the elevator 2 of each building 1, and an elevator 2 and an information center 3 And a monitoring line 4 for communication connection therebetween. As the monitoring line 4, for example, a telephone line, an IP (Internet Protocol) line or the like can be used.

The elevator 2 includes an elevator device 21 and an elevator control system 24 having a control device 22 and a monitoring device 23.

Control data for controlling the operation of the elevator device 21 is set in the control device 22. Here, the control data is data used when the control device 22 controls the operation of the elevator device 21, and specifically includes, for example, a control program, a control parameter, and the like.

The control device 22 controls the operation of the elevator device 21 according to the set control data. Specifically, for example, the control device 22 controls the operation of the elevator hoisting machine, the operation of the elevator car door, and the like as the operation of the elevator.

The monitoring device 23 is communicably connected to the control device 22 and connected to the information center 3 via the monitoring line 4. The monitoring device 23 monitors the state of the elevator device 21 and periodically transmits monitoring data as monitoring results to the information center 3 as monitoring information. Moreover, when abnormality occurs in the elevator apparatus 21, the monitoring device 23 transmits a notification signal for notifying the abnormality to the information center 3 as monitoring information.

When the monitoring device 23 receives control information described later from the information center 3, the monitoring device 23 transmits the control information to the control device 22. The monitoring device 23 has a function of performing a communication switching process described later.

The information center 3 includes a communication device 31, a monitoring server 32, a control server 33 provided independently of the monitoring server 32, and an operation terminal 34.

The communication device 31 has a function of transmitting and receiving data, and communicates with the monitoring device 23 of the elevator control system 24 via the monitoring line 4. The communication device 31 is shared by the monitoring server 32 and the control server 33.

The monitoring server 32 receives monitoring information from the monitoring device 23 by the communication device 31 as communication performed with the elevator control system 24.

Thus, the monitoring server 32 performs communication (hereinafter referred to as monitoring communication) for receiving monitoring information from the elevator control system 24 by the communication device 31 with the elevator control system 24.

The control server 33 transmits control information to the monitoring device 23 by the communication device 31 as communication performed with the elevator control system 24. Specifically, the control server 33 transmits control information to the monitoring device 23 by the communication device 31 in accordance with a request from the operation terminal 34 described later or a specified schedule. Here, the control information is information related to the control of the control device 22. Specifically, for example, the control data for setting in the control device 22 and the old control data already set in the control device 22 are updated. Control data for updating, a command signal for instructing the control device 22 to perform a diagnostic operation for diagnosing whether or not the elevator device 21 is abnormal.

Thus, the control server 33 performs communication (hereinafter referred to as control communication) for transmitting control information to the elevator control system 24 by the communication device 31 with the elevator control system 24.

The operation terminal 34 is configured to be operable by maintenance personnel and the like, and requests the control server 33 to transmit control information to the monitoring device 23 according to the operation of the maintenance personnel and the like.

Next, communication switching processing performed by the elevator remote monitoring system according to the first embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing a series of communication switching processes performed by the elevator remote monitoring system according to the first embodiment of the present invention.

Note that a series of processes in the flowchart of FIG. 2 is performed while the control communication is performed between the elevator control system 24 and the control server 33, specifically, the monitoring device 23 receives control information from the control server 33. Repeatedly while receiving.

In step S101, the monitoring device 23 determines whether or not a specific situation has occurred. The specific situation here means a situation where monitoring communication needs to be performed between the elevator control system 24 and the monitoring server 32. Moreover, as such a specific situation, the situation where the elevator control system 24 must transmit the alert signal mentioned above to the monitoring server 32 is mentioned, for example.

In step S101, if it is determined that a specific situation has occurred, the process proceeds to step S102. If it is determined that a specific situation has not occurred, the process ends.

In step S102, the monitoring device 23 performs switching determination for determining whether to switch from the control communication with the control server 33 to the monitor communication with the monitoring server 32.

Here, the switching determination described above will be described. As a first example of switching determination, there is a method in which a priority for control communication is defined in advance for each content of monitoring communication, and it is determined whether to switch from control communication to monitoring communication according to the content of monitoring communication. It is done.

That is, as described above, the contents of the monitoring communication include monitoring data that is periodically transmitted and a notification signal that is transmitted when an abnormality occurs in the elevator apparatus 21. Regarding the monitoring data and the alert signal, the alert signal is higher than the alert data in terms of urgency.

Therefore, when the content of the monitoring communication is the transmission of the notification signal, the priority is set higher than that of the control communication, and the switching determination is configured to determine that the control communication is switched to the monitoring communication. On the other hand, when the content of the monitoring communication is transmission of monitoring data, the priority is set lower than that of the control communication, and the switching determination is configured not to switch from the control communication to the monitoring communication.

As described above, in the first example of the switching determination, it is determined whether to switch from the control communication to the monitoring communication according to the content of the monitoring communication.

As a second example of the switching determination, there is a method of estimating the necessary communication time required for completing the control communication and determining whether to switch from the control communication to the monitoring communication according to the estimated necessary communication time.

That is, when the control communication is not yet completed and the control communication is switched to the monitoring communication, the control communication is interrupted and the monitoring communication is started, and the control communication is resumed after the monitoring communication is completed. Therefore, the shorter the required communication time, the more efficient it is to start the monitoring communication after the control communication is completed.

Therefore, when the estimated necessary communication time is equal to or greater than a preset threshold value, the switching determination is configured to determine that the control communication is switched to the monitoring communication. On the other hand, when the estimated necessary communication time is less than a preset threshold value, the switching determination is configured not to switch from the control communication to the monitoring communication.

As described above, in the second example of the switching determination, the required communication time required until the control communication is completed from the processing time of step S102 is estimated, and whether the control communication is switched to the monitoring communication according to the estimated required communication time. It is determined whether or not.

Returning to the description of FIG. 2, if it is determined in step S102 to switch from control communication to monitoring communication, the process proceeds to step S103, and if it is determined not to switch from control communication to monitoring communication, The process ends.

In step S103, the monitoring device 23 disconnects the control communication with the control server 33, and the process proceeds to step S104. As a result, the communication connection between the monitoring device 23 and the control server 33 is disconnected from the monitoring device 23 side.

In step S104, the monitoring device 23 establishes a communication connection with the monitoring server 32 by transmitting a connection request to the monitoring server 32. Subsequently, the monitoring device 23 performs monitoring communication with the monitoring server 32, and the process ends.

Thus, the elevator control system 24 performs switching determination when a specific situation occurs while control communication is being performed between the elevator control system 24 and the control server 33. Moreover, the elevator control system 24 cut | disconnects the control communication currently performed between the elevator control system 24 and the control server 33, when it determines with switching switching from control communication to monitoring communication. The elevator control system 24 performs monitoring communication between the elevator control system 24 and the monitoring server 32 after disconnecting the control communication.

As described above, according to the first embodiment, the elevator remote monitoring system performs the switching determination when a specific situation occurs during the control communication between the elevator control system and the control server. It is configured. In addition, when the elevator remote monitoring system determines in the switching determination that the control communication is switched to the monitoring communication, the control communication performed between the elevator control system and the control server is disconnected, and the elevator control system and the monitoring are monitored. Ensure that monitoring communication is performed with the server.

In the first embodiment, as a specific example of the configuration of the elevator remote monitoring system described above, the elevator control system side is configured to perform switching determination, disconnection of control communication, and establishment of monitoring communication. Illustrated.

With the configuration described above, when a situation occurs in which the elevator communicating with the control server needs to communicate with the monitoring server, the communication connection destination of the elevator can be switched from the control server to the monitoring server as necessary. . In addition, if the priority of transmission of the alarm signal in monitoring communication is set higher than that in control communication, even if an abnormality such as confinement in a passenger's car occurs, the abnormality is promptly monitored. Can be notified.

Embodiment 2. FIG.
In the first embodiment, the elevator remote monitoring system configured such that switching determination, disconnection of control communication, and establishment of monitoring communication are performed by the elevator control system 24 side has been described. On the other hand, in the second embodiment of the present invention, the elevator is configured such that the switching determination and the control communication are disconnected by the information center 3 side, and the monitoring communication is established by the elevator control system 24 side. A remote monitoring system will be described. In the second embodiment, description of points that are the same as those of the first embodiment will be omitted, and points different from the first embodiment will be mainly described.

FIG. 3 is a flowchart showing a series of communication switching processes performed by the elevator remote monitoring system according to the second embodiment of the present invention.

Note that the series of processes in the flowchart of FIG. 3 is performed while the control communication is performed between the elevator control system 24 and the control server 33, specifically, the monitoring device 23 receives control information from the control server 33. Repeatedly while receiving.

In step S201, the control server 33 determines whether a specific situation has occurred. Here, as a specific example of the method in which the control server 33 determines whether or not a specific situation has occurred, for example, the following method can be cited.

That is, when a specific situation occurs, the monitoring device 23 of the elevator control system 24 transmits a specific signal to the control server 33 using a communication line different from the communication line used to perform control communication. . If the control server 33 has received the specific signal, the control server 33 determines that a specific situation has occurred.

Returning to the description of FIG. 3, if it is determined in step S201 that a specific situation has occurred, the process proceeds to step S202. If it is determined that a specific situation has not occurred, the process ends. It becomes.

In step S202, the control server 33 performs a switching determination for determining whether to switch from the control communication between the elevator control system 24 and the control server 33 to the monitoring communication between the elevator control system 24 and the monitoring server 32. Here, as a specific example of the method in which the control server 33 determines whether to switch from control communication to monitoring communication, for example, the following method can be considered.

That is, the specific signal described above is configured to include the content of the monitoring communication corresponding to the specific situation, and the control server 33 grasps the content of the monitoring communication based on the received specific signal, and performs the above-described switching determination. It is comprised so that the process similar to the example of 1 may be performed. As another example, the control server 33 is configured to perform the same processing as in the second example of the switching determination described above.

Returning to the description of FIG. 3, if it is determined in step S202 that the control communication is switched to the monitoring communication, the process proceeds to step S203, and if it is determined that the control communication is not switched to the monitoring communication, The process ends.

In step S203, the control server 33 disconnects the control communication with the monitoring device 23, and the process proceeds to step S204. Thereby, the communication connection between the monitoring device 23 and the control server 33 is disconnected from the control server 33 side.

In step S204, the monitoring device 23 establishes a communication connection with the monitoring server 32 by transmitting a connection request to the monitoring server 32 in response to the disconnection of the control communication from the control server 33 side. Subsequently, the monitoring device 23 performs monitoring communication with the monitoring server 32, and the process ends.

Thus, the control server 33 performs switching determination when a specific situation occurs while control communication is performed between the elevator control system 24 and the control server 33. In addition, when the control server 33 determines in the switching determination that the control communication is switched to the monitoring communication, the control server 33 disconnects the control communication performed between the elevator control system 24 and the control server 33. The elevator control system 24 performs monitoring communication between the elevator control system 24 and the monitoring server 32 when the control communication is disconnected from the control server 33 side.

As described above, according to the second embodiment, the control server performs the switching determination when a specific situation occurs while the control communication is performed, and determines that the control server switches from the control communication to the monitoring communication. It is configured to disconnect communication. The elevator control system is configured to perform monitoring communication with the monitoring server when the control communication is disconnected from the control server side. Even with such a configuration, the same effect as in the first embodiment can be obtained.

The center side monitoring system 37 and the center side control system 38 are provided independently.

The communication device 35 has a function of transmitting and receiving data, and communicates with the monitoring device 23 of the elevator control system 24 via the monitoring line 4. The monitoring server 32 receives the monitoring information transmitted from the monitoring device 23 by the communication device 35.

The communication device 36 has a function of transmitting and receiving data, and communicates with the monitoring device 23 of the elevator control system 24 via the monitoring line 4. The control server 33 transmits control information to the monitoring device 23 by the communication device 36 in accordance with a request from the operation terminal 34 described later or a specified schedule.

Thus, in the configuration of the elevator remote monitoring system shown in FIG. 4, the monitoring server 32 and the control server 33 use individual communication devices without sharing the communication devices. Therefore, in the configuration shown in FIG. 4, compared with the configuration shown in FIG. 1, the monitoring server 32 corresponds to the control server 33 even when the communication amount of the control server 33 fluctuates and increases more than expected.
