Abstract

Device for making use of information relating to the breakdowns detected by a central unit (2) of an aircraft, the unit being linked via an address and data bus (4) to a first memory (6) storing this information, comprising a second non-volatile memory (7) which is removable and connectable to said bus (4) and in which the information contained in the first memory (6) may be recopied so as to process it in a computing center.

Claims

1. A device, adapted to be used in an aircraft, for generating and storing aircraft breakdown data, comprising:

means for detecting an aircraft breakdown condition and generating aircraft breakdown data in response thereto;

first memory means for storing said aircraft breakdown data at a number of addresses beginning at a first address, said first memory means being coupled to said detecting means via an address and data bus;

second memory means connectable to and removable from said address and data bus, said second memory means being non-volatile;

presence testing means for determining whether said second memory means is connected to said address and data bus;

means for generating a request that said aircraft breakdown data be copied from said first memory means to said second memory means so that said second memory means can be removed and moved to a location remote from said first memory means after said aircraft breakdown data has been copied into said second memory means;

means for copying said aircraft breakdown data from said first memory means to a number of addresses beginning with a second address in said second memory means upon said generation of said request, said copying means including;

means for reading and storing said first address beginning at which said aircraft breakdown data is stored in said first memory means, said second address beginning at which said aircraft breakdown data is to be stored in said second memory means, and said number of addresses of said aircraft breakdown data to be copied from said first memory means to said second memory means;

means for transferring a portion of said aircraft breakdown data stored in said first memory means at said first address to said second memory means at said second address;

means for periodically incrementing said first address in said first memory means and said second address in said second memory means; and

means for determining whether all of said aircraft breakdown data stored in said first memory means has been copied to said second memory means.

2. The device as claimed in claim 1, additionally comprising integrated circuit means for interconnecting said second memory means to said detecting means.

3. The device as claimed in claim 1, additionally comprising a removable module, said second memory means being installed on said removable module.

4. The device as claimed in claim 3, additionally comprising a second module on which said removable module is carded and on which said detecting and generating means is carded.

5. The device as claimed in claim 4, additionally comprising a backplane bus, said second module being connected to said backplane bus, and wherein said removable module comprises connection means permitting removal of said removable module without disconnecting said second module from said backplane bus.

6. The device as claimed in claim 3, wherein said first memory means comprises a centralized polling module disposed at a site and wherein said removable module is installed at said site of said centralized polling module of said first memory means.

7. An apparatus, comprising:

means for detecting an aircraft breakdown condition and generating aircraft breakdown data in response thereto;

first memory means for storing said aircraft breakdown data at a number of addresses beginning at a first address, said first memory means being coupled to said detecting means via an address and data bus;

second memory means connectable to and removable from said address and data bus, said second memory means being non-volatile;

presence testing means for determining whether said second memory means is connected to said address and data bus;

means for generating a request that said aircraft breakdown data be copied from said first memory means to said second memory means so that said second memory means can be removed and moved to a location remote from said first memory means after said aircraft breakdown data has been copied into said second memory means;

a maintenance computer for coupling to said second memory means, said maintenance computer comprising means for automatically processing said aircraft breakdown data; and

means for copying said aircraft breakdown data from said first memory means to a number of addresses beginning with a second address in said second memory means upon said generation of said request, said copying means including;

means for reading and storing said first address beginning at which said aircraft breakdown data is stored in said first memory means, said second address beginning at which said aircraft breakdown data is to be stored in said second memory means, and said number of addresses of said aircraft breakdown data to be copied from said first memory means to said second memory means;

means for transferring a portion of said aircraft breakdown data stored in said first memory means at said first address to said second memory means at said second address;

means for periodically incrementing said first address in said first memory means and said second address in said second memory means;

means for determining whether all of said aircraft breakdown data stored in said first memory means has been copied to said second memory means.

8. The apparatus as claimed in claim 7, additionally comprising integrated circuit means for interconnecting said second memory means to said detecting means.

9. The apparatus as claimed in claim 7, additionally comprising a removable module, said second memory means being installed on said removable module.

10. The apparatus as claimed in claim 9, additionally comprising a second module on which said removable module is carried and on which said detecting and generating means is carried.

11. The apparatus as claimed in claim 10, additionally comprising a backplane bus, said second module being connected to said backplane bus, and wherein said removable module comprises connection means permitting removal of said removable module without disconnecting said second module from said backplane bus.

12. The apparatus as claimed in claim 9, wherein said first memory means comprises a centralized polling module disposed at a site and wherein said removable module is installed at said site of said centralized polling module of said first memory means.
