Description

  The present invention relates to a remote monitoring system using a communication line, and more particularly to a large-scale remote monitoring and monitoring system having a plurality of local monitoring units and a plurality of remote monitoring units.

  A conventional remote monitoring system includes a local device and a remote device that can receive monitoring information through a communication line at a position distant from the local device. With such a system, the monitored location can be monitored at a position distant from the local device.

  In such a remote monitoring system, authentication for the purpose of security is required between the local device and the remote device. In Patent Document 1, the remote monitoring system permits a connection after a local device performs authentication in response to a connection request from a remote device.

  Further, in Patent Document 1, the remote monitoring system operates in a state where the allowable traffic amount is ignored in the information amount of monitoring information exchanged between the local device and the remote device.

The command transmitted from the remote control unit 20 to the remote monitoring unit 20 and the message transmitted from the arbitration server 40 to the remote monitoring unit 20 are displayed.

  In the present embodiment, a similar main screen corresponding to a plurality of local monitoring units 10 is also prepared. Thereby, similarly to the remote monitoring unit 20, it is possible to grasp the data transmission / reception status between the local monitoring unit 10 and the arbitration server 40.

  The connection management function of the arbitration server 40 collectively manages authentication for the purpose of security between the plurality of local monitoring units 10 and the plurality of remote monitoring units 20. The connection management function of the arbitration server 40 manages the increase / decrease in the number of units of the plurality of local monitoring units 10 and the plurality of remote monitoring units 20. For example, when a new remote monitoring unit 20 is newly added to the large-scale real-time remote monitoring system 1 of the present invention, first, the remote monitoring unit 20 installed with dedicated software is newly connected to the communication line 30. Next, when “communication test” in the pull-down menu 55 of the menu 54 of the main screen 50 shown in FIG. 3 of the arbitration server 40 is selected, a communication test screen 60 shown in FIG. 4 is displayed. By inputting a test command to the input unit 61 of the communication test screen 60, it is possible to test whether communication with the newly added remote monitoring unit 20 has been established. Next, information on the newly added remote monitoring unit 20 is set on the IP setting screen 70 shown in FIG.

  In this embodiment, a communication test screen and an IP setting screen corresponding to a plurality of local monitoring units 10 are also prepared. Thereby, the local monitoring unit 10 can be newly added by the operation in the arbitration server 40.

  When the status information of the newly added local monitoring unit 10 or remote monitoring unit 20 is immediately transmitted to the arbitration server 40 or when a communication test is performed, the newly added local monitoring unit 10 and remote monitoring unit 20 You may comprise so that information may be set up automatically.

  Further, when the number of local monitoring units 10 and remote monitoring units 20 is reduced, the rows of the local monitoring unit 10 and the remote monitoring unit 20 to be reduced are designated on the respective IP setting screens 70 and the row deletion button 72 is pressed. Thereby, the local monitoring unit 10 and the remote monitoring unit 20 can be easily reduced by the arbitration server 40.

  Further, the traffic volume control function of the arbitration server 40 is used when the monitoring information is transmitted from the local monitoring unit 10 to the remote monitoring unit 20, the transmission capability of the local monitoring unit 10, the traffic capability of the communication line 30, and the remote monitoring unit 20. The amount of traffic in the monitoring information is monitored and controlled based on the receiving capability of each of the remote monitoring units 20 and the priority order set in advance in each of the plurality of remote monitoring units 20.

  Specifically, the traffic amount control function is actually transmitted by each local monitoring unit 10 based on the state information of the local monitoring unit 10 described above, the information on the traffic amount of the communication line 30 and the state information of the local monitoring unit 10 described above. Calculate the traffic volume of monitoring information. Information on the traffic amount of the communication line 30 may be acquired from a server (not shown) owned by a plurality of providers and a control device (not shown) managing the communication line 30 such as a line control device. Good. When a server owned by a provider goes down, the traffic amount of the monitoring information can be controlled by switching the monitoring information exchange to another operating provider.

  The traffic volume control function registers the allowable traffic volume of each local monitoring unit 10 in the database of the arbitration server 40 in advance. The allowable traffic amount can be set to any value as long as it is less than the theoretical value.

  In each local monitoring unit 10, by comparing the traffic volume of the monitoring information actually transmitted with the allowable traffic volume, the arbitration server 40 can connect the number of remote monitoring units 20 that can be further connected to each local monitoring unit 10. To decide.

  In the present embodiment, the traffic amount of the monitoring information is controlled based on a preset priority order. For example, when “IP setting” in the pull-down menu 55 of the menu 54 of the main screen 50 shown in FIG. 3 of the arbitration server 40 is selected, the IP setting screen 70 shown in FIG. 5 is displayed.

  The priority of each remote monitoring unit 20 can be set by inputting the priority in the priority setting column 71 of each remote monitoring unit 20 in the IP setting screen 70.

  Further, the traffic volume control function may register the priorities of the remote monitoring units 20 in the database of the arbitration server 40 in advance.

  FIG. 6 is a flowchart showing processing that is advanced by the arbitration server 40 of this embodiment when determining the remote monitoring unit 20 to be connected to the local monitoring unit 10 based on the priority order.

  In step 80, a connection request is transmitted from the new remote monitoring unit 20 to the predetermined local monitoring unit 10 to the arbitration server 40. In step 81, the traffic volume of the monitoring information actually transmitted is compared with the allowable traffic volume. If a new remote monitoring unit 20 can be further connected to the predetermined local monitoring unit 10, the processing of the arbitration server 40 proceeds to step 82. In step 82, the arbitration server 40 permits a predetermined remote monitoring unit 10 to connect a new remote monitoring unit 20.

  If the new remote monitoring unit 20 cannot be further connected to the predetermined local monitoring unit 10, the processing of the arbitration server 40 proceeds to step 83. In step 83, the arbitration server 40 compares the priority of the connected remote monitoring unit 20 with the priority of the new remote monitoring unit 20.

  If the priority of the new remote monitoring unit 20 is higher than the priority of the connected remote monitoring unit 20, the processing of the arbitration server 40 proceeds to 84. In step 84, the arbitration server 40 notifies the new remote monitoring unit 20 of waiting for connection. Next, in step 85, the arbitration server 40 notifies the remote monitoring unit 20 having the lowest priority among the connected remote monitoring units 20 to forcibly disconnect the connection. Next, in step 86, the arbitration server 40 instructs the predetermined local monitoring unit 10 to disconnect the remote monitoring unit 20 having the lowest priority among the connected remote monitoring units 20, or the remote having the lower priority. The monitoring unit 20 disconnects itself. Finally, in step 87, the arbitration server 40 permits connection of a new remote monitoring unit 20.

  If the priority of the new remote monitoring unit 20 is lower than the priority of the connected remote monitoring unit 20, the processing of the arbitration server 40 proceeds to 88. In step 88, the arbitration server 40 notifies the remote monitoring unit 20 that has newly made a connection request of connection refusal.
