DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a monitoring system according to the present invention will be described below. FIG. 1 shows a specific example of a monitoring system. This monitoring system is provided in the transmission system. As shown in the figure, the monitoring system includes a monitoring device 1 and a plurality of monitored devices 2-1 to 2-n whose operations are monitored by the monitoring device 1. Each of the monitored devices 2-1 to 2-n performs an operation required for transmission. Therefore, if the transmission specifications are different, the types and the number of monitored devices to be mounted are different. Also, with the change of specifications,
After starting the transmission operation, the monitoring system may add a new monitored device or delete an existing monitored device. Each monitored device 2-1 to 2-n
Sends an operation status signal indicating the status of the operation to the monitoring device 1.

[0008] The monitoring device 1 comprises an activation control unit 11, a transmission time control unit 12, a function control unit 13, and a communication control unit 14. The activation control unit 11 causes the monitoring device 1 to switch the monitored devices 2-1 to 2-n when the entire monitoring system is activated or when the monitored device related to the addition or deletion described above is activated. Perform the necessary actions to monitor.
At the time of activation, the transmission time control unit 12 transmits data indicating the time at which the operation status signal is transmitted to the monitored devices 2-1 to 2-2
-N. For this purpose, the transmission time control unit 12
It has a table section 12a indicating the correspondence between the monitored devices 2-1 to 2-n and the time at which the operation status signal is transmitted. This correspondence is determined by the reception processing capability of the monitoring device 1 or
The determination is made in consideration of the overall processing capability, which is the sum of the reception processing capability of the monitoring device 1 and other processing capabilities. More specifically, the correspondence is determined so that the reception processing of the operation status signal by the monitoring device 1 does not exceed the reception processing capability, or the processing related to the command signal and the response signal is not delayed.

FIG. 2 is a diagram showing the correspondence between the monitored device and the transmission time. For example, assuming that the monitored device 2-1 is the first monitored device and the monitored device 2-2 is the second monitored device, the monitored device 2-1 has an operation status. The time at which the signal is transmitted is 00 seconds per hour, and the time at which the monitored device 2-2 transmits the operation status signal is 01 seconds per hour.

The function control unit 13 includes the monitored devices 2-1 and 2-2.
-Control the function that n performs. The communication control unit 14 transmits and receives an operation status signal, a command signal, and a response signal to and from the monitored devices 2-1 to 2-n.

Each of the monitored devices 2-1 to 2-n includes:
It comprises an operation status information collection unit 21, an operation status information storage unit 22, a communication control unit 23, a function control unit 24, and a transmission time storage unit 25. The operation status information collection unit 21 receives, from the function control unit 24, operation status information indicating an operation status of a function for transmission, which the function control unit 24 is responsible for. The operation status information storage unit 22 stores the collected operation status information by the operation status information collection unit 21. The communication control unit 23 sends the operation status information stored in the operation status information storage unit 22 to the monitoring device 1 at the transmission time of the operation status signal. The function control unit 24 plays a part of functions necessary for performing transmission, and outputs operation state information indicating the operation state to the operation state information collection unit 21. The transmission time storage unit 25 stores the transmission time of the operation status signal received from the monitoring device 1.

FIG. 3 is a flowchart showing the operation of the monitoring system of the specific example. Hereinafter, the operation of the monitoring system of the specific example will be described with reference to this flowchart. Step S10: When the monitoring system is entirely started up, or when only the monitored device related to addition or deletion is partially started up, the startup control unit 11 sets the communication control unit 14 to start. Then, the type, the number, the device number, etc. of the mounted monitored devices 2-1 to 2-n are confirmed. More specifically, the activation control unit 11 collects information on each monitored device from the monitored devices 2-1 to 2-n.

Step S11: The activation control unit 11 refers to the table unit 12a to execute the monitored device 2-
The transmission time of the operation status signal corresponding to 1-2-n is notified. For example, the monitoring device 1 notifies the monitored device 2-1 of the transmission time “00 hours / minute / minute”, and similarly notifies the monitored device 2-2 of the transmission time “hour / minute / 01 seconds”. .

Step S12: Monitored devices 2-1 and 2-2
-N stores the received transmission time in the transmission time storage unit 25. Step S13: The operation status information collection unit 21 receives the operation status information indicating the operation status from the function control unit 24 at regular time intervals or at arbitrary time intervals. Step S14: The operation status information collection unit 21 stores the received operation status information in the operation status information storage unit 22. Thereafter, the operations of step S13 and step S14 are repeated.

Step S15: When the communication control unit 23 determines that the transmission time has come by referring to the transmission time storage unit 25, the communication control unit 23 uses the operation status information stored in the operation status information storage unit 22 as an operation status signal. Transmit to monitoring device 1. For example, the communication control unit 23 of the monitored device 2-1
Sends the operation status information to the monitoring device 1 at the transmission time of 9:00:00, and sends the communication control unit 23 of the monitored device 2-2.
Sends the operation status information to the monitoring device 1 at a transmission time of 9:00:01.

Step S16: Monitored devices 2-1 and 2-2
-N, the communication control unit 23
Is transferred to a monitoring / control device (not shown) which is a higher-level device. The communication control unit 23 may monitor the monitoring device 1 as necessary.
The operation status signal is displayed to the operator who operates by using a display unit or an alarm unit (not shown).

As described above, according to the specific example of the monitoring system, the operation status information collection units 21 of the plurality of monitored devices 2-1 to 2-n always perform the operations related to the functions of the respective devices. Is collected, and the collected operation state information is stored in the operation state information storage unit 22. However, the monitored devices 2-1 and 2-2
Each communication control unit 23 of −n sends each operation status signal to the monitoring device 1 only at the transmission time of the operation status signal designated by the monitoring device 1. Therefore, it is possible to prevent the operation status signal from being momentarily concentrated on the monitoring device 1. As a result, the monitoring device 1 sets the monitored device 2-
It is possible to reliably receive all the operation status signals transmitted by 1 to 2-n. That is, it is possible to avoid a state in which the monitoring device 1 cannot completely receive the operation status signal.

Since concentration of a plurality of operation status signals can be avoided, the monitoring apparatus 1 can avoid delay in processing of command signals and response signals requested by the operator. Such dispersion of the operation status signal contributes to equalization of the load to be processed by the monitoring device 1.

In the monitoring system of the specific example described above, the table unit 12a indicates the correspondence between the monitored devices 2-1 to 2-n and the transmission times. Instead of this correspondence, the table unit 12a may show the correspondence between the number of monitored devices 2-1 to 2-n and the transmission time interval. For example, if the number of monitored devices is two, the transmission time interval is two seconds, if three, three seconds, and so on. Assuming that the number of monitored devices is two, the monitoring device 1 instructs both monitored devices to transmit an operation status signal every two seconds, for example. By specifying the transmission time in this way, the same effect as that of the monitoring system of the specific example can be obtained.

In the monitoring system of the specific example described above, the transmission times at which the monitored devices 2-1 to 2-n transmit the operation status signals are all different from each other. Specifying transmission times completely different is particularly effective when the number of monitored devices 2-1 to 2-n is large. However, when the number of monitored devices 2-1 to 2-n is small, the concentration of the operation status signals can be reduced without completely changing the transmission times. Setting the transmission time in this way allows the reception of the operation status signal to be repeated at the same time. However, since the number of monitored devices 2-1 to 2-n is small, even if there is overlap of reception of the operation status signal, the monitoring device 1 determines that the reception process cannot be performed in time or other processes are delayed. Can be avoided.

For adding or deleting a monitored device, the method of communication between the monitoring device and the monitored device is determined. When a large number of monitored devices are added, intensive reception of the operation status signal is performed. It is also possible to switch from the method of permitting to the method of prohibiting, or conversely, if many monitored devices are deleted, the method of prohibiting the intensive reception of the operation status signal from the method of permitting intensive reception.
