[0001] 1. Field of the Invention [0002] The present invention relates to a pseudo test apparatus, and more particularly to a pseudo test apparatus used for performing a verification test of software operation of a device under test.

[0002]

2. Description of the Related Art As an example of a conventional pseudo test apparatus of this type, there is a "maintenance and operation apparatus verification method using a pseudo apparatus for a heterogeneous exchange interface" described in JP-A-4-123562. In this heterogeneous exchange interface pseudo device, all interface information is managed collectively.

FIG. 4 is a block diagram showing an example of a conventional maintenance and operation equipment verification system, and FIG. 5 is a block diagram showing a configuration of a heterogeneous exchange interface simulating apparatus in FIG. 4, which is the same as that described in the above publication. is there.

Referring to FIG. 4, the prior art includes a heterogeneous exchange interface simulating device 5 for generating and transmitting and receiving interface information between a plurality of heterogeneous exchanges and a maintenance operation device for centrally maintaining them. The interface information from the heterogeneous exchange interface pseudo device 5 is connected to the maintenance operation device 6 via the communication device 8, the pseudo device terminal 9 is connected to the heterogeneous exchange interface pseudo device 5, and the subordinate of the maintenance operation device 6 is controlled. When used together with the maintenance terminal 7, transmission / reception confirmation of interface information and error isolation are performed.

As shown in FIG. 5, the heterogeneous exchange interface simulating device 5 includes an interface information registration / generation control receiving unit 51, a processor unit 52, a main storage unit 53, an interface control common unit 54, Secondary storage control unit 55, secondary storage unit 56, interface unit 5
7, 58,..., 59.

In this pseudo device, one heterogeneous exchange interface simulating device 5 can be prepared without preparing a heterogeneous exchange.
The opposition test with the maintenance operation device 6 can be performed only by the above.

[0007] That is, the different-type exchange interface pseudo device 5 receives interface information unique to each exchange, which is input from the pseudo device terminal 9 in advance before the facing test.
The information is stored in the secondary storage unit 56 via the interface information registration / generation control reception unit 51, the processor unit 52, the main storage unit 53, and the secondary storage control unit 55.

Then, the interface information stored in the secondary storage unit 56 is instructed to be pulled up to the main storage unit 53 by the input from the pseudo device terminal 9, and the interface information of the interface units 57, 58,. A transmission / reception preparation instruction is performed, and a request from the maintenance operation device 6 and an interface information transmission instruction from the pseudo device terminal 9 are waited.

In this case, the interface information input from the maintenance operation device 6 is transferred to the interface units 57, 58,
, 59, and received by the interface control common unit 54.
Then, it is stored in the main storage unit 53 via the processor unit 52.

The processor unit 52 identifies the stored information, and obtains necessary interface information based on the interface information stored in advance in the secondary storage unit 56 for each different model and for each interface in accordance with an input instruction from the pseudo device terminal 9. Stored in the storage unit 53, the interface unit 5
, 59, and transmits the selected interface information to the maintenance and operation device 6 under the control of the processor unit 52 and the interface control common unit 54.

In this way, the interface information stored in advance for each different-type exchange and for each interface is matched with the received information from the maintenance / operation device 6 side, and the interface information from the different-type exchange interface simulated device 5 side to the maintenance / operation device 6 is sent to the maintenance operation device 6. According to the transmission instruction of necessary interface information, 1
The exchange between the plurality of heterogeneous exchanges and the maintenance operation device is realized by the plurality of heterogeneous exchange interface simulating devices 5.
