Description

DETAILED DESCRIPTION OF THE INVENTION [Overview] Regarding a large-scale variable processing method in a monitoring system, the status change of a large number of monitored objects is expressed in 1,0 bits for the purpose of deleting the queue area and reducing the load on the central processing unit. In the large-scale state change processing method in the monitoring system for receiving and notifying the received data, the state change reception processing means and the judgment processing means are provided, and the state change reception processing means receives the data and detects the state change for each monitored object. The state change management table having the current values is updated, and if it is not being processed, the state change management table is notified if the state change, current value, The state change and current values of all monitoring targets in the determination table having the previous value are updated with those of the state change management table, and the state change determination is performed using the updated current value and the previous value.

[Industrial application field]

The present invention relates to a method of processing a large amount of state change data in a monitoring system such as operation / stop of each part of a communication network and monitoring of normality / failure.

[Conventional technology]

An example of a conventional monitoring system of this type is shown in FIG. 10a, 10
b, ...... is the monitoring target, 12a, 12b is the monitoring target status (normal /
A device for collecting malfunctions, operating / stopping, etc., 14 is a central processing unit, and 20 is a display device. Monitoring target 10a,
The states of 10b, ... Are expressed by bits, and when detecting the state change (state change) of the monitoring target, the collecting devices 12a, 12b send the current values of all monitoring targets of the station to the central processing unit 14. This transmission data 22 is like 2110101, the first 2 indicates the address of the collecting device 12b in this example, and the subsequent 110 ... Are status bits of the monitoring target. The status bit is 1 bit for 1 object,
For example, 0 indicates normal and 1 indicates failure. The collection device has the status bit (group) of the previous monitoring target, compares it with the current status bit (group), and if even one bit is different, attaches its address to the current status bit It is sent to the processing device 14, and the current status bit is replaced with the previous status bit and saved.

In the central processing unit 14, the occurrence / restoration determination processing means 14a compares the received data with the corresponding data (status bit having the same address) in the current value table 16 and edits the determination result message 24 for the changed bit. It is passed to the message edit output processing means 14b, and the corresponding column of the current value table (file or main memory) is updated with new data. The judgment result message 24 is like "23 occurrence". The first "2" indicates the address (indicates 12b), the next "3" indicates the third bit of the status bit (s), and the last "occurrence". Indicates that the third bit has changed from 0 to 1 (for example, a failure has occurred). The message edit output processing means 14b searches the name file 18, finds that "23" is "XX device", sends message data such as "XX device failure occurred" to the display device 20, and Display alarm etc.

[Problems to be solved by the invention]

 The problems of this conventional method are as follows.

When a large number of messages are received in a short time, messages waiting to be processed are queued, which makes it difficult to design the queue area. For example, if the queue area is set small, the area becomes insufficient when the load is high, and if it is set large, the area is wasted when the load is low.

In electronic equipment, failure / normality may be repeated for an extremely short period of time. In this case, the collecting device detects the data 22 every time when the device is in failure or normal, and the load on the central processing unit becomes high. Such short-time failure / normality repetition does not need to be processed for each failure and normality, and it is often acceptable to collectively process them as one failure occurrence and recovery.

The present invention seeks to improve these points, and aims to delete the queue area and reduce the load on the central processing unit.

[Means for solving problems]

According to the present invention, the status change acceptance processing is performed in the mass status change processing method in the monitoring system in which the status change of a large number of monitoring targets (10a, 10b, ...) Is received by the data (22) represented by 1 and 0 bits and is notified. Means (14c) and judgment processing means (14d) are provided, and the state change acceptance processing means receives the data (22),
The state change management table (24) having the state change and the current value is updated for each monitored object, and if it is not being processed, the determination processing means (14d) is notified of activation, and the determination processing is performed upon receiving the activation notification. The means updates the status change and current values of all the monitoring targets of the judgment table (26) having the status change, the current value, and the previous value for each monitoring target with that of the status change management table, and The current value and the previous value are used to determine the state change.

[Action]

When the state change acceptance processing means receives the data (22) representing the state change of each monitoring target from the collection device and updates the state change management table, this process is performed via a line or the like. Queuing is not necessary because it is performed in a short time compared to the time required to send the modified data.

The state change determination process is collectively performed by the determination processing unit for all monitoring targets (all addresses). The determination process is performed only when the status change bit is 1 (where the status changes). These reduce the load on the central processing unit and make queuing unnecessary.

〔Example〕

Detailed description will be given with reference to FIG. 1. In the present invention, the occurrence / recovery determination processing means 14a of the central processing unit 14 of FIG. 3 is divided into two processing means, a state change acceptance processing means 14c and a determination processing means 14d,
The state change data is transferred during this time by using the state change management table 24 prepared in advance for all the addresses (all the state changes and current values of the state change management table are copied to the determination table 26). Further, two flags A and B are used, and the flag A indicates whether or not the state change acceptance processing means 14c has updated the state change management table 24, and is cleared when the judgment processing means 14d finishes copying the table. Further, the flag B indicates whether or not the determination processing means 14d is operating.

Similar to FIG. 3, the collecting devices 12a and 12b send the transmission data 22 to the central processing unit 14 when the monitored object has a state change. The state change acceptance processing means 14c transmits the transmission data (state change message) 22.
Flag is set (A ← 1), the received data is compared with the corresponding current value in the state change management table 24 (exclusive OR operation is performed), and the state change bit at the different point is set to 1. To do. In this example, since the transmission data is 2011011 and the current value of the address 2 of the status change management table 24 is 000001,
Taking these EORs results in 010010, which is used as the status change bit of address 2 in the status change management table 24. Then, the current value of the address is rewritten to the received value, the flag B is checked, and if B = 1, the processing ends (thus, only the status change and the current value of the address 2 in the status change management table are updated), If B = 0, B = 1 is set and the determination processing means 14d is notified of activation.

Upon receiving the activation notification, the judgment processing means 14d first copies all the status changes and current values of all the addresses in the status change management table 24 to the status changes and current value columns of all the addresses in the judgment table 26. After copying, all the bits of the state change of the state change management table 24 are set to 0, and the flag A is returned to 0. Next, since the previous value is recorded in the determination table 26, the previous value and the current value are compared. As shown in FIG. 2 (a), this is carried out only for the case where the state change bit is 1. In this example, the bits whose state change is 1 are the second bit and the fifth bit,
The previous value of the second bit is 0, the current value is 1, and the fifth bit has both the previous value and the current value. Based on the comparison result, the actual state change transition is determined as shown in FIG. 2 (b).

That is, if the previous value is 0 and the current value is 1, this is a failure. If the previous value is 1 and the current value is 0, this is a failure recovery. If the previous value and the current value are 0, this is a failure, but in a short time. It is recovered (while the previous value is written in the judgment table and then the current value is written next). If both the previous value and the current value are 1, this means that the failure has been recovered but the failure has returned to the failure in a short time.

Such occurrence / restoration determination is performed, a determination message is sent to the display device 20, and then the determination processing means 14d
Can rewrite the previous value in the determination table to the current value. Next, the flag A is checked, and if A = 0, the flag B is lowered (B ← 0) and the processing is completed.

Data 22 is sent from the collection devices 12a and 12b each time there is a change in the state of the monitored object, and thus when failure / normality is repeated in a short time, the data 22 is sent for each failure / normality. Only by updating the state change management table with this data, the determination process is required to copy the data of all the addresses of the state change management table to the determination table and perform the failure occurrence / recovery determination for all the addresses of the determination table. Do it at a cycle of more than an hour. Therefore, a buffer for the transmission data 22 is not necessary, the load on the central processing unit is not so large, and it is possible to catch a short-term occurrence / recovery repetition failure (however, the processing for each repetition is not performed). .

〔The invention's effect〕

As described above, according to the present invention, since the status change acceptance processing is only the status change bit update, it can be processed in a short time.
Judgment processing receives data from the table, judges all addresses, and is not restarted during the judgment operation, so queuing is not necessary. Even if there is a situation that repeats many times within one judgment time, this Is ignored and only the final result is sent, so that the number of messages is reduced, the load is reduced, and determination is performed by bit operation, which enables high-speed processing.
