Problems solved by technology

As a result, other interfaces used by other systems using the replacement IMA module are often not verified because 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 TurnAroundTime (Turnaround 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

The method involves executing an elementary system test unit (415'-1) that is independent from one out of a set of computing modules (400-1, 400-2, 400-3, 400-4), where the system test unit is associated to a testing system used for testing input / output interfaces (400-11, 400-12, 400-13, 400-14), of the computing modules. Execution result of the elementary system test unit is transmitted to a maintenance computer that is distinct from the computing modules. Initialization of the elementary system test unit is performed in response to control of an operator input via the maintenance computer. Independent claims are also included for the following: (1) a computer program comprising a set of instructions for implementing a method for testing an input / output interface of an integrated modular avionic type computing module in an aircraft (2) a device for testing an input / output interface of an integrated modular avionic type computing module in an aircraft (3) an aircraft comprising a testing device.

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, new-generation 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 systems to share same hardware components. This development allows reducing the number of different hardware elements in the aircraft, thus reducing the costs of development and qualification. [0003] For this purpose, already in the form of module, especially CPIOM (the acronym of English t...
