[Industrial application field]

The present invention relates to a failure device analysis system for a maintenance system that centrally maintains and operates a plurality of electronic exchanges.

Along with the development of the 15DN network, various communication networks connecting electronic exchanges have also been developed. Therefore, in the midst of the diversified development of communication networks, there is a strong demand for reliability and labor saving in the maintenance and operation of electronic exchanges.

2. Description of the Related Art Conventionally, maintenance systems have been equipped with a diagnostic function as a means for identifying a faulty device when a device failure occurs in an electronic exchange, or furthermore, when a device failure occurs in the maintenance system itself. However, when a failure occurs in a plurality of electronic exchanges, etc., there is a risk that failure handling and diagnostic functions will be inconsistent, leading to a situation in which user tests, etc., cannot be performed.

[Prior Art] FIG. 3 shows a configuration diagram of a conventional failure device analysis system for an electronic exchange. In the figure, 251 to 25. , a plurality of electronic exchanges, 21 a maintenance system for centrally maintaining these electronic exchanges, 22 a diagnostic program for processing fault handling and diagnostic functions of the maintenance system, and 23 a storage device for storing a diagnostic dictionary of the diagnostic program. , 24 indicate maintenance system terminals connected to the maintenance system and performing maintenance and operation work for each electronic exchange.

Multiple electronic exchanges 25. ~25n is an l5DN related exchange or PBX, and can accommodate up to 128 units,
Normally, up to 35 units can be accommodated and centrally maintained by the maintenance system 21. The maintenance system terminal 24 is a PC,
It consists of WS, STD, etc., and has the function of testing the exchange and displaying the system status of the exchange using the maintenance system 21, and is capable of providing commands to a specific exchange based on the information received from the exchange. .

The above are the original functions of the maintenance system terminal 24,
In addition, diagnose faults in the exchange using the diagnostic program 22,
It is also possible to diagnose a faulty exchange by exchanging data using the maintenance system terminal 24. In other words, when it is determined that a package consisting of electronic exchanges is at fault, the diagnosis is performed by time sharing to check the specific type of diagnosis, equipment type, etc. for each exchange, so the data is shared online with the maintenance system 21. There will be more exchanges.

[Problem to be solved by the invention]

In conventional maintenance systems, the original function is the maintenance test function of electronic exchanges, but when a device failure occurs in the electronic exchange or in the maintenance system itself, a diagnostic function is used to identify the faulty device. was provided. However, when a failure occurs in a plurality of electronic exchanges, there is a problem in that failure handling and diagnostic functions become inconsistent, leading to a situation in which the original function such as user testing cannot be performed.

The present invention relocates the diagnostic dictionary search function (diagnostic search program, diagnostic dictionary) that was in the maintenance system from the maintenance system to the faulty device analysis system, performs all diagnostic dictionary searches, etc. in the faulty device diagnosis system, and The purpose of the terminal is to allow users to concentrate on their primary maintenance and testing functions.

A faulty device analysis system 3 is provided between the maintenance system 1 and the maintenance system terminal 2, and when a fault message sent from the maintenance system 1 due to a fault in the electronic exchange 9 or the maintenance system 1 is received by the maintenance system terminal 2. At the same time, the information is also transferred to the failure device analysis system 3, and the failure history information stored in the failure analysis system 3 is searched and displayed at a timely manner using the failure analysis terminal 8 connected to the failure device analysis system 3.

[Effect]

(1) The maintenance system 1 transfers a device failure message from the electronic exchange 9 or the like to the failure device analysis system 3 at the same time as the maintenance system terminal 2 .
