Abstract
A system for real time simulation of the environment of an aeroengine includes a digital computer having its inputs switched by a selection module included in the computer either to a respective sensor or else to a substitution digital bus configured to convey substitution digital data generated by a real time simulator.
Claims7
1-6. (canceled)
7:
- A system comprising:
- at least one digital computer configured to control an engine in an aircraft, each digital computer comprising:
- at least one input configured to receive data representative of a state of a sensor;
- at least one output configured to be connected to at least one actuator;
- and
- a regulation module configured to send at least one command via the output to the at least one actuator as a function of data received by at least one input;
- the system further comprising:
- a selection module included in the at least one digital computer and configured to switch the input either to the sensor or else to a substitution bus as a function of an instruction from an operator;
- a real time simulator for simulating at least some of an environment of the engine and of aircraft, the simulator comprising:
- a digital output configured to send at least one substitution item of digital data over the substitution bus to the input of the at least one digital computer;
- and
- a digital input connected to the at least one output of the digital computer and configured to receive the at least one command issued by the at least one digital computer, the real time simulator configured to simulate reaction of the engine and of the aircraft to the command;
- and
- a verification module included in the at least one digital computer, configured to implement a verification procedure for preventing the at least one input of the digital computer from being switched to the substitution bus by the selection module when the aircraft is in flight.
11 more elements
8:
- A system according to claim 7, wherein the selection module is implemented by a software module constituting an interface between the at least one input and the regulation module.
9:
- A system according to claim 7, further comprising means for connecting or disconnecting the output that is connected to the actuator to or from the input of the simulator.
10:
- A system according to claim 7, comprising two engines and two of the digital computers that are mutually interconnected by a physical connection, each of the computers configured to control one of the engines.
11:
- A system according to claim 7, wherein the verification procedure is implemented as soon as the at least one digital computer is switched on, the verification module configured to:
- verify that the input is switched to the sensor;
- verify a determined code in a determined address of a memory of the system;
- and
- verify that at least one determined frame is received in a determined time.
2 more elements
12:
- A system according to claim 11, wherein the verification module includes means for overwriting the code in event of at least one of the verification steps failing.
