FIG. 2 shows the route of monitoring information. Figure 2
14a, 14b, 14c, 14d are a plurality of monitoring targets that notify the status, 13 is a status control monitoring device, 1
5a, 15b, 15c, and 15d are monitoring targets 14a to 14
It is a communication path connecting d, and data is transmitted in the order of the monitoring target 14a, the monitoring target 14b, the monitoring target 14c, and the monitoring target 14d.

Next, the operation of this configuration will be described. In FIGS. 1 and 2, the initial states of the monitoring targets 14a to 14d are registered in the corresponding old state storage units 20a ... 20n.

When an abnormality occurs in the communication path 15a between the monitoring targets 14a and 14b, the status of the monitoring target 14b, the monitoring target 14c, the monitoring target 14d, and the monitoring target 14a is maintained while the abnormality continues. The control monitoring unit 13 is notified of the occurrence of an abnormality in the communication path 11a. The state monitoring unit 16 constantly monitors the state notifications notified from the monitoring targets 14a to 14d, and activates the state stability detection unit 18 when the state notifications change.

The state stability detector 18 monitors the objects 14a-1.
After receiving the first communication path abnormality from 4d, a timer is set for each of the monitoring targets 14a to 14d, and the system waits for receiving the next notification. The state stability detector 18 resets the timer when it receives the next notification, and considers that the state is stable when a time-out occurs, and processes the same plurality of pieces of information as one group. When the state is stabilized by the state stability detection unit 18, the inconsistency detection unit 22 monitors the monitoring target 14a ...
14d and the stored contents of the corresponding old state storage units 20a ... 20n are read and all of them are compared. If there is no mismatched item in this comparison, the process ends, and if there is a mismatched item, the monitoring targets 14a to 14d and the old state storage units 20a ... 20.
The unmatched items in n are registered in the new state unmatched item storage unit 24 and the old state unmatched item storage unit 26, respectively.

The state determination unit 28 compares the stored contents of the new state non-matching item storage unit 24 and the old state non-matching item storage unit 26, and the state of the notified monitoring targets 14a to 14d, that is, no fault, fault occurrence. And determine the failure recovery,
The result is displayed on the status display unit 30.

When it is determined that a fault has occurred or a fault has been recovered, the states of the corresponding monitoring targets 14a to 14d are re-registered in the old state storage units 20a ... 20n, and the same operation is performed at the next state change.

In this way, the monitoring targets 14a to 14d
By grouping the information notified from the monitoring target of 1 group, the plurality of information generated by 1 state change can be 1 group.
Recognize as one piece of information.

Further, all states of the monitoring targets 14a to 14d are stored in the old state storage units 20a to 20n, and when the latest state notification is received, the old state storage units 20a to 20n and the monitoring targets 14a to 14d notify. By comparing and determining the states to be performed by the mismatch detection unit 22 and the state determination unit 28,
It is possible to promptly detect the occurrence of an abnormality, the restoration and the abnormal portion of the monitoring states 14a to 14d and display them on the state display unit 30.

[0025]

As is apparent from the above description, the LAN supervisory control device of the present invention makes the information notified from the monitoring state into one group, so that the plurality of information generated by one state change can be treated as one. It has the effect of being recognized as one piece of information.

Further, by storing all the states of the object to be monitored and comparing the stored state with the state to be notified when the latest state notification is received, it is possible to quickly detect the occurrence of an abnormality in the monitored object. This has the effect of being able to detect and restore abnormal points.
