Abstract
Methods are provided for supervising a motor control unit with at least two separate channels, each of the two channels including at least: means for executing a given application task AS, the application task AS including a plurality of successively executed computations between which latency periods elapse; a first component capable of performing the computations; a second component capable of storing data; the application tasks AS of the channels being capable of communicating. The method includes the following steps: a) detecting a latency period; b) performing, during this latency period, an operating state test of at least one of the components; and c) determining a state of the component corresponding to a failure state or a healthy state.
Claims10
A method for supervising an engine control unit of a turbomachine with at least a first channel and a second channel, each of the first channel and the second channel comprising a calculator and:
- means for performing an application task, the application task comprising a plurality of successively executed calculations between which latency periods elapse;
- a first component for carrying out the successively executed calculations of said application task, from input data;
- a second component adapted to store data;
- the application task executed by the first channel and the application task executed by the second channel communicating with each other, the method comprising the following steps during a current execution cycle of the application task for each of the first channel and the second channel:
- a) detecting a latency period during which the application task is waiting for data to perform calculations;
- b) performing, during the latency period, an operational state test of at least one of the first or second components;
- and
- c) determining a state of said at least one of the first component or the second component, wherein the state corresponds to a failure state or a healthy state.
A method for supervising an engine control unit of a turbomachine with at least a first channel and a second channel, the method comprising the following steps during a current execution cycle of an application task carried out by each of the first channel and the second channel:
- a) detecting a latency period during which the application task is waiting for data to perform calculations;
- b) performing, during the latency period, an operational state test of at least one component of the first channel and the second channel;
- and
- c) determining a state of said at least one component, wherein the state corresponds to a failure state or a healthy state.
