Problems solved by technology

As a result, other interfaces used by other systems using the replacement IMA module are often not verified, since it is generally not possible to perform all system tests on all avionics systems using the replacement module (which can take hours and maintenance is often only called TAT (an acronym for the English term Turn Around Time (Turn Around Time)) limited time for component replacement)

Embodiment Construction

[0043] The invention is directed to the testing of IMA-type modules having some input / output interfaces used by several applications, certain input / output interfaces considered to be for the device comprising the module usually aircraft, especially after the module has been replaced Operational safety is critical.

[0044] To this end, the invention employs a system test whose execution is limited in time while respecting the safety constraints of the avionics system, comprising one or more applications hosted at least in part by a module. More precisely, during the installation of the module, the invention intends to stimulate only the input / output interfaces of the avionic systems hosted by the module, not covered by the interaction test, and not the I / O interfaces used by these same avionic systems Input port / output port of other modules. To reduce maintenance time, it is also possible to test only the critical input / output ports of the module.

[0045] Thus, the inventio...

Abstract

Input / output interfaces of avionic modules of IMA type in a device including several modules is tested. A system includes at least one application employed by a set of computer modules. This set includes the computer module (a first module), and at least one other computer modul (at least one second module). A system test is associated with the at least one system for functionally testing the set of computer modules according to the system. The system test includes at least one elementary system test for functionally testing at least one input / output interface of the first module. The execution of the at least one elementary system test is independent of the at least one second module. At least one result of execution of the at least one elementary system test is transmitted to a maintenance computer distinct from the computer modules of the plurality of computer modules.

Description

technical field [0001] The present invention relates to the maintenance of electronic modules, and more particularly to a method and a device for testing the input / output interfaces of an IMA type avionics module, especially at the time of module replacement. Background technique [0002] Avionics systems such as the fuel and landing management systems of older aircraft use their inherent computers, peripherals, wiring, input / output interfaces, sensors and drives. Instead, newer aircraft use a structure called IMA (an acronym for the English term "Integrated Modular Avionic"), according to which a hardware part is distinguished from a software part, allowing multiple avionics The systems share the same hardware elements. This development allows reducing the number of different hardware elements in the aircraft, thus reducing the costs of development and qualification. [0003] For this reason, module, especially CPIOM (English term "Core Processing Input Output Module (cor...
