RESERVATION METHOD OF CHANNELS OF STRUCTURAL AND FUNCTIONAL MODULES OF AIRBORNE DIGITAL COMPUTERS ON THE BASIS OF INTELLIGENT DIAGNOSTIC SYSTEM UNDER CONDITIONS OF INTEGRATED MODULAR AVIONICS Russian patent published in 2022 - IPC G06F11/20 G06N3/02 

FIELD: computing systems.

SUBSTANCE: the invention relates to a method for reserving channels of structural and functional modules (CFM) of onboard digital computing systems (OCVS) of aircraft (LA) based on an intelligent diagnostic system (IDS) under integrated modular avionics. The technical result is to increase the reliability of the on-board digital computing systems. In the method, by means of a control device, which is a neurocontroller, IDS training is performed in real time, where the IDS and the neurocontroller use multilayer unidirectional artificial neural networks of direct propagation with a sigmoid activation function of neurons in the hidden layer, and a linear activation function of neurons in the output layer, as well as multilayer radial basic networks, in the process of the aforementioned training with a certain discreteness, with the help of a control device, they are fed to block for forming a training sample and tolerance limits data of input and output signals of each QPSK channel with the subsequent construction of functional dependencies of the data of the output signals of each QPSK channel BTsVS on the input signals and determining the tolerance limits of functional dependencies, which are the boundaries of the operable state of the QPSK channels, while assigning a higher rank to those QPSKs that are more consistent with increasing the efficiency of using the aircraft, and the tolerance limits are formed in such a way that the higher the rank of the diagnosed with With the help of the IDS QPSK, the lower the value of the anticipatory tolerance, as a result of training, databases are formed with data on the functioning of the QPSK BTsVS in the pre-failure state and in the failure mode, after training the IDS by means of a control device using the generated databases, the approach of the input and output signals of the QPSK channels to the tolerance limits of the functional dependence is fixed and the control action is applied to the IDS to switch from the failed channel of the QPSK BTsVS to the IDS, transferring the IDS into the operating mode as a backup channel for the failed BTsVS QPSK channel.

EFFECT: to increase the reliability of the on-board digital computing systems.
