[Problems to be Solved by the Invention] The conventional device fault collection method described above has the following problems. (1) In the conventional method, power alarms, fan failures, etc. of each device are sent directly to the alarm display device using ground signals, so if the system maintenance personnel are in the same station building as the system, Although there is no problem, in the case of remote maintenance using an unmanned station or a centralized maintenance center, a device for transmitting an alarm to the remote maintenance center is also required. (2) With the conventional method, alarms could only be displayed on devices dedicated to alarm display.

[0006] The purpose of the present invention is to achieve the above (1) and (2).
In contrast to the conventional maintenance services shown in Figure 1, we have realized a maintenance method that is more advanced and has better serviceability, and that immediately switches the type of failure to the standby system, and that replaces problems caused by standby system power alarms, fan failures, etc. A device fault collection method that improves the efficiency of fault processing and collection, allowing the collection and reporting of important faults or non-urgent faults without affecting the throughput of online exchange processing. Our goal is to provide the following.

[0007]

[Means for Solving the Problems] The present invention provides a device failure collection method in a distributed switching system including a plurality of processors including a standby system each connected to a common bus. It includes an alarm collection processor dedicated to collecting alarms, and an alarm information bus that connects the alarm collection processor to the plurality of processors, and each of the plurality of processors detects and processes device failures and collects predetermined failure information. The apparatus is characterized in that it includes fault information processing means for sending out fault information to the alarm collection processor via the alarm information bus.

Further, in the present invention, the fault information processing means includes a first alarm detection section that detects first fault information with high urgency, and a second alarm detection section that detects second fault information with low urgency. an alarm detection unit; and a system control unit that switches the processor to a standby system based on information from the first alarm detection unit;
and an alarm sending section that sends information from the second alarm detection section to the alarm collection processor.

[0009]Furthermore, the present invention provides that the second fault information is
Preferably, it is a standby system power alarm and fan failure, and a standby system clock loss.

0010

[Function] When each processor detects a highly urgent failure by the failure information processing means, it immediately switches to the standby processor. In the event of a clock loss, this fault information is sent to the alarm collection processor via the alarm information bus. In addition, in the case of a highly urgent failure, important failures are similarly collected by the alarm collection processor.

[0011] Therefore, it is possible to realize a maintenance system that is highly advanced and has high serviceability, and to improve the efficiency of fault processing and collection.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention, and FIG. 2 is a block diagram showing details of the processor.

In this embodiment, a call processing processor 2a, an O&M processor 3a, a switch control processor 4a, and an information communication processor 5a are used as a plurality of processors including a standby system connected to a common bus 7, respectively.
and a switch 1 connected to a switch control processor 4a, the present invention is characterized by an alarm collection system provided separately from the plurality of processors 2a to 5a. a dedicated alarm collection processor 6; this alarm collection processor 6 and the plurality of processors 2a to 5;
Each of the plurality of processors 2a to 5a detects a device failure and sends predetermined failure information to the alarm collection processor 6 via the alarm information bus 8. A first alarm detection unit (1) 21 detects a fault type (1) 11 which is a first fault with a high degree of urgency, and a second fault which is a second fault with a low urgency. A second alarm detection unit (2) 22 that detects failure type (2) 12 and a system control unit 23 that switches the processor to a standby system based on information from the alarm detection unit (1) 21 .
and an alarm sending unit 24 that sends information from the alarm detection unit (2) 22 to the alarm collection processor 6.

[0015] Here, the type of failure (2) 12 is:
These are standby system power alarm and fan failure, and standby system clock failure.

Although FIG. 2 shows the call processing processor 2a as a processor, the same applies to other processors.

Next, the operation of this embodiment will be explained.

Now, the case where a failure occurs in the call processing processor 2a will be explained with reference to FIG.

First, when a fault occurs, the alarm detection section (1) 21 or (2) 22 detects the fault depending on the content of the fault. Since the failure type (1) 11 detected by the alarm detection unit (1) 21 requires urgent switching of the system to the standby system, the system control unit 23 is activated.

On the other hand, the alarm detection section (2) 22
The failure type (2) 12 detected in 12 includes a power alarm in the standby system, a fan failure, and a clock disconnection in the standby system as described above, and notifications of these failures are sent to the alarm collection processor 6. In order to do this, information from the alarm detection section (2) 22 is sent by the alarm sending section 24 to the alarm collection processor 6 via the alarm information bus 8. In the case of failure type (2) 12, the processor does not activate the system control unit 23, so there is almost no effect on the online exchange operation.

The alarm collection processor 6 compiles the information received from the alarm detection units (2) 22 of each of the processors 2a to 5a, further analyzes the information, and assigns alarm notification destinations to the O & D in the system according to each alarm type.
The notification is sent to the M processor 3a or the information communication processor 5a to a remote maintenance center (not shown). The O&M processor 3a that receives the fault information prints the fault information on a system console or the like in order to notify the maintenance person of the fault information. Further, the information communication processor 5a not only transmits the received information to the remote maintenance center, but also can notify the fault information to the maintenance person within the own station or at a remote location without affecting the replacement operation of the faulty processor.

Note that the alarm detection unit (1) 21 also notifies the alarm collection processor 6 via the alarm sending unit 24 of a predetermined important failure.

[0023]

As explained above, the present invention provides a dedicated processor and bus for collecting alarms in a distributed switching system composed of a plurality of processors, and each processor in the system receives alarms with high urgency. Alarm detection unit (1), less urgent alarm detection unit (2)
, a system control unit that switches the processor to the standby system based on information from the alarm detection unit (1), and an alarm transmission unit that sends information from the alarm detection unit (2) to the alarm collection processor. This makes it possible to realize a maintenance method that is more advanced and has richer serviceability.
Alarms are divided into those that immediately switch to the standby system, and those that require reporting, such as power alarms and fan failures, which have already been switched to the standby system and replaced normally. Since it can be detected, not only can important failures be appropriately reported, but even less urgent failures can be collected and reported without affecting the processing capacity of online exchange processing, improving the efficiency of failure handling and collection. It has the effect of
