FIG. 1 is a schematic flow chart diagram of a method for online adjustment of aircraft engine control parameters, according to one embodiment of the present disclosure. In some embodiments, the following method steps for online adjustment of aircraft engine control parameters are performed by an electronic controller.
In step 101, on-off state information of the upper computer of the rack is collected. The switch state information comprises on-line parameter adjusting reset switch state information and on-line parameter adjusting enabling switch state information.
In some embodiments, the collected signals are processed by de-jittering, voting, or the like.
For example, in the anti-shake process, the acquired state is determined when the acquired state is consistent in five consecutive sampling periods.
For another example, In the voting process, since all Built-In self-tests (BITs) of the switching values are power-on self-tests, and only one Test is performed at power-on, the BIT fault state of the Channel circuit is used as a first detection value, and the fault state of a Cross Channel Data Link (CCDL) of dual Channel communication is used as a second detection value. And if both the detections are faults, outputting a default value. If the CCDL is in fault and the BIT of the channel is effective, the switching value of the channel is taken as the standard. If CCDL is effective, no matter whether the BIT of the channel is in fault or not, the BIT state of the opposite channel is required to be acquired for judgment. If CCDL and BIT of both channels are normal, the signal states of the two channels need to be voted, namely, the operation can be executed under the condition that all the channels are effective, otherwise, the operation is not executed.
In step 102, the current state of the online parameter adjusting reset switch and the current state of the online parameter adjusting enable switch are identified according to the switch state information.
In some embodiments, the current state of the on-line parameter-adjusting reset switch and the current state of the on-line parameter-adjusting enable switch are identified according to the on-line parameter-adjusting reset switch state information and the on-line parameter-adjusting enable switch state information.
In step 103, if the on-line parameter-adjusting reset switch is in an off state, the on-line parameter-adjusting enable switch is in an on state, and the engine is in a preset state, the current mode of the electronic controller is switched to an on-line parameter-adjusting mode, and mode switching feedback information is fed back to the upper computer of the rack.
In some embodiments, the preset state comprises: the engine is in a slow-driving state or a state above slow-driving, and the acceleration and deceleration state of the engine is a steady state.
For example, when the engine enters the online parameter adjustment mode, the online parameter adjustment mode flag is set to 1.
In some embodiments, if the online parameter adjusting reset switch and the online parameter adjusting enable switch are both currently in an off state, and the electronic controller is currently in the online parameter adjusting mode, the current mode of the electronic controller is switched to the non-online parameter adjusting mode, the online parameter adjusting mode flag is set to 0, and the current effective values of all the parameters are kept unchanged.
In some embodiments, if the online parameter-adjusting reset switch is currently in the on state, the online parameter-adjusting enable switch is currently in the off state, and the electronic controller is currently in the online parameter-adjusting mode, the current mode of the electronic controller is switched to the non-online parameter-adjusting mode, the online parameter-adjusting mode flag is set to 0, and the currently effective values of all the parameters are set to the corresponding preset values. For example, the preset value is a parameter value before the engine is started.
In some embodiments, in the case that the electronic controller is currently in the online parameter adjusting mode, if the engine enters other states except the slow-moving state and the state above slow-moving state from the slow-moving state or the state above slow-moving state, the current mode of the electronic controller is switched to the offline parameter adjusting mode, the online parameter adjusting mode flag is set to 0, and the currently effective values of all the parameters are set to the corresponding preset values. For example, the preset value is a parameter value before the engine is started.
In some embodiments, the electronic controller interacts with the gantry host computer via ARINC429 or ARINC664 communication protocols.
In step 104, after receiving the adjusted parameter information sent by the bench host computer, the current effective value of the corresponding parameter is updated by using the adjusted parameter information.
In some embodiments, after receiving the adjusted parameter information sent by the upper computer of the bench, the adjusted parameter information is checked. And if the called parameter information passes the verification, updating the current effective value of the corresponding parameter by using the called parameter information. And if the adjusted parameter information does not pass the verification, feeding back verification failure information to the bench upper computer so that the bench upper computer regenerates and sends the adjusted parameter information according to the user operation.
In some embodiments, verifying the tuned parameter information includes at least one of a parameter identification verification, a parameter range verification, or a two-channel consistency verification. The parameter identification verification comprises the steps of extracting parameter identification from the adjusted parameter information, and determining that the adjusted parameter information passes the verification if the parameter identification is within a preset identification range. The parameter range check comprises the steps of extracting parameter values from the adjusted parameter information, and determining that the adjusted parameter information passes the check if the parameter values are within a preset value range. The dual-channel consistency check comprises the step of determining that the adjusted parameter information passes the check under the condition that the parameter value received by the electronic controller is consistent with the parameter value received by the upper rack computer, wherein the electronic controller and the upper rack computer interact through CCDL.
In some embodiments, the verification is performed in sequence according to the order of parameter identification verification, parameter range verification, or dual-channel consistency verification. If the current check does not pass, the subsequent check does not need to be executed.
In some embodiments, in the process of updating the current effective value of the corresponding parameter by using the called parameter information, the parameter identifier and the corresponding parameter value are extracted from the called parameter information, and the current effective value of the parameter associated with the parameter identifier is updated to the corresponding parameter value.
In some embodiments, the gantry host computer, to avoid the electronic controller from being unable to correctly receive the loss of the tuned parameter information, may continue to send the currently generated tuned parameter information until the next tuned parameter information location is to be sent.
In step 105, the parameter adjustment feedback information is fed back to the bench upper computer, so that the bench upper computer presents the parameter adjustment feedback information.
In some embodiments, the parameter adjustment feedback information includes at least one of a parameter validation time, a parameter verification result, or a parameter current validation value. The user can know whether the parameter adjustment is successful or not through the parameter adjustment feedback information displayed by the upper computer of the rack.
In the method for adjusting the control parameters of the aero-engine online provided by the embodiment of the disclosure, the parameters of the engine are adjusted online, so that the test time can be effectively saved, and the test period is shortened.

In step 604, the electronic controller feeds back the mode switching feedback information to the gantry upper computer.
In step 605, the bench upper computer determines whether the electronic controller enters an online parameter adjusting mode according to the mode switching feedback information. And if the electronic controller does not enter the online parameter adjusting mode currently, returning to the step 601, otherwise, executing the step 606.
In step 606, the gantry upper computer generates tuned parameter information according to user operations. The called parameter information comprises parameter identification and corresponding parameter value.

If the electronic controller updates the current effective value of the corresponding parameter by using the adjusted parameter information, the parameter adjustment feedback information indicates that the parameter adjustment is successful; and if the adjusted parameter information does not pass the verification, the parameter adjustment feedback information indicates that the parameter adjustment fails.
In step 611, the bench host computer determines whether the parameter adjustment is successful according to the received parameter adjustment feedback information. If the parameter adjustment is not successful, the process returns to step 506. If the parameter adjustment is successful, the parameter adjustment process is finished.
