DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for collecting alarms in an apparatus, and more particularly to a method for periodically transmitting a collection frame to each connection destination in the apparatus and collecting an alarm in the apparatus by a response frame. An in-device alarm collection device suitable for a device in which both an alarm (high-priority alarm) issued due to a failure and an alarm (low-priority alarm) that is incidentally detected due to the failure may simultaneously occur. About.

[0002]

2. Description of the Related Art Conventionally, this type of in-device alarm collection system has
It has an alarm unit that transmits and receives collection frames for alarm collection, and multiple connection destinations that receive the collection frames and responds to the alarm unit with detected alarms. Each connection destination receives the collection frames. Then, all types of alarms are transmitted to the alarm unit, and the alarm unit refers to the high-priority / low-priority alarm list table and selects a low-priority alarm to be processed as no occurrence from the alarms collected from each connection destination. The discrimination was removed and only the high-priority alarm was processed with priority.

FIG. 5 is a block diagram showing a conventional in-device alarm collecting device. In FIG. 5, the alarm unit 1 periodically generates a collection frame 10 in the frame generation unit 2 and sends it to each connection destination 5, and the frame processing unit 4 outputs a response frame transmitted from each connection destination 5. Processing is performed and the alarm processing unit 3 is notified. At each connection destination 5, when the frame receiving unit 6 receives the collection frame 10 from the alarm unit 1, the alarm detected by the alarm detection circuit 7 is notified to the frame response unit 9,
The frame response unit 9 sends a response frame to the alarm unit 1.

The alarm processing unit 3 of the alarm unit 1 collects all types of alarms of each connection destination, refers to and compares the high-priority / low-priority alarm list table, and processes the low-priority alarms as no occurrence. Alarms are identified and only high priority alarms are collected and processed. That is, there are cases where both an alarm (high-priority alarm) issued due to a certain failure and an alarm (low-priority alarm) that is incidentally detected due to the failure are generated. , In such a case, the low priority alert is treated as having no alert.

[0005]

As described above, in the conventional alarm collection device, the alarm processing unit 3 of the alarm unit 1 applies a high-priority / low-priority alarm to all alarms collected from each connection destination 5. There is a problem that the list table must be referred to and compared, and the processing takes time.

An object of the present invention is to reduce the processing time for discriminating between a high-priority alarm and a low-priority alarm in an in-device alarm collection system.

Another object of the present invention is to simultaneously generate both an alarm (high-priority alarm) issued due to a certain failure and an alarm (low-priority alarm) which is incidentally detected due to the failure. It is an object of the present invention to provide an in-apparatus alarm collection method capable of shortening the processing time for issuing only a high-priority alarm when the alarm is issued.

[0008]

According to the present invention, a high-priority alarm occurrence identifier is separated from a response frame from a connection destination, and if a high-priority alarm is detected,
A frame processing unit for notifying the frame generation unit of the information; and a frame generation unit for generating a high-priority alarm occurrence state identifier upon receiving the notification and transmitting a collection frame to which the high-priority alarm occurrence state identifier is added. An alarm unit, a frame receiving unit that receives a collection frame from the alarm unit and notifies the emission prohibition setting unit when confirming the high-priority alarm generation state identifier, and notifies the alarm detection circuit when the notification is received. The connection destination is provided with an emission prohibition setting unit that notifies the frame response unit that only the low-priority alarm among the alarms that have been issued does not generate an alarm.

That is, according to the present invention, the high-priority / low-priority alarm notification determination processing is performed in each connection destination in a distributed manner, and the alarm unit receives the high-priority alarm from the connection destination.
It is characterized in that transmission of a low priority alarm is prohibited to a connection destination and transmission of only a high priority alarm is instructed to be transmitted as a response signal. Therefore, it is not necessary to collect all the alarms in the alarm unit and perform the high-priority / low-priority alarm notification determination processing, so that the processing can be sped up.

[0010]

FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, an alarm unit 1 periodically generates a collection frame 10 by a frame generation unit 2 and sends it to each of the connection destinations 5.1 to 5.2. The high priority alarm occurrence identifier is separated from the response frames from 1 to 5.2. The frame processing unit 4
If a high-priority alarm is detected as a result of processing the response frame, the information is notified to the frame generation unit 2. Upon receiving the notification, the frame generation unit 2 adds the high-priority alarm occurrence state identifier and sends out the collection frame 10.

At each of the connection destinations 5.1 to 5.2, the alarm detected by the alarm detection circuit 7 is notified to the frame response unit 9 through the emission inhibition setting unit 8, and the frame response unit 9 transmits the response frame. Send out. In the frame receiving unit 6,
The high-priority alarm occurrence state identifier of the collection frame 10 is confirmed through the high-priority alarm occurrence state identifier confirmation unit 7, and if the high-priority alarm occurrence state identifier is added, the emission prohibition setting unit 8
Notify.

Upon receiving the notification, the emission prohibition setting unit 8 prohibits the transmission of the low-priority alarm which is processed as no occurrence of the alarm notified from the alarm detection circuit 7, and outputs only the high-priority alarm to the frame response unit 9. Notify. Frame response unit 9
Returns only the high-priority alarm sent from the emission prohibition setting unit 8 to the frame processing unit 4 of the alarm unit 1 as a response frame.

The frame processing unit 4 performs protection for one cycle to notify the alarm processing unit 3 of the collection result to which the high-priority alarm occurrence information is added.

Next, the operation of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. The high-priority alarm is generated in the alarm detection circuit 7 of the connection destination 5.1, and the low-priority alarm is generated in the 5.2 alarm detection circuit 7 of the connection destination.
Is notified to the frame processing unit 4 of the alarm unit 1 through the network (see FIG. 2).

The frame processing unit 4 separates the high-priority alarm identifier from the response frame, and detects the high-priority alarm as a result of processing the response frame, and notifies the frame generation unit 2 of the information. Upon receiving the notification, the frame generation unit 2 generates a high-priority alarm occurrence state identifier and sends out the collection frame 10.

Each of the frame receiving sections 6 of the connection destinations 5.1 and 5.2 confirms the high priority alarm occurrence state identifier of the collected frame 10 through the high priority alarm occurrence state identifier confirmation section 7,
Each emission prohibition setting unit 8 is notified of a command to inhibit the issuance of a low priority alarm.

At the connection point 5.1, a high-priority alarm is generated, and the alarm is notified to the frame response section 9 as it is and sent to the frame processing section 4 of the alarm section 1. on the other hand,
At the connection destination 5.2, since a low-priority alarm has been generated, the generation of the alarm is prohibited by the emission prohibition setting unit 8, and no alarm is transmitted from the frame response unit 9 (see FIG. 3).

The frame processing section 4 notifies the alarm processing section 3 of the alarm to which the high-priority alarm generation information from the connection destination 5.1 has been added as a collection result after a protection period of one cycle has elapsed.

FIG. 4 shows a general embodiment in which the number of connection destinations is n. However, the present invention is also applicable to the case where n = 1. That is, the present invention can be applied to an in-device alarm collection device having one or more arbitrary number of connection destinations.

[0020]

According to the present invention, the high priority / low priority alarm notification determination processing is performed in parallel at each connection destination, so that the time for the determination processing can be greatly reduced.
