First, referring to FIG. 1, the entire system may include a computing resource 110 and a vehicle 120. The vehicle 120 may be a helicopter or may be a vehicle such as an airplane 121, but is not limited thereto. The computing resource 110 and the vehicle 120 may be connected or communicated by wireless or wired, and the computing resource 110 may be included in the vehicle 120.

The vehicle vibration control software update processing method performed by the computing resource may perform an automatic analysis and update function to minimize manpower, cost, and time-consuming tasks for updating the control software.

In operation 210, the computing resource may receive acceleration information measured by each sensor located in the target vehicle from the target vehicle. For example, when a vehicle is on the ground after operation, the vehicle may transmit a value of a data log of the vehicle to a computing resource disposed in a data center through a wireless network. The computing resource may receive from the vehicle a value of the data log transmitted by the vehicle.

In operation 220, the computing resource may determine whether vibration generated by each sensor, corresponding to the received acceleration information, is out of an allowable range. For example, the computing resource may analyze the acceleration magnitude for each sensor position based on the value of the received data log.

In step 230, computing resources may adjust sensor weights for specific sensors for which vibrations generated by each sensor are outside of acceptable ranges. For example, the computing resource compares the first vibration level of the first sensor located at the first location with the second vibration level of the second sensor located at the second location, and the first vibration level is different from the second vibration level. The sensor weight of the first sensor or the second sensor may be adjusted.

For example, computing resources can increase the sensor weight of a sensor where it needs to reduce vibration more, causing the sensor to generate smaller vibrations, while a sensor where vibration is low enough decreases the sensor weight so that the sensor By generating higher vibrations at present, vibration reduction simulation can be performed using the modified set of sensor weights. In addition, the computing resource may be repeatedly calculated until the convergence to a state similar to the designed acceleration distribution to derive the update weight.

For example, the computing resource may increase the sensor weight of the first sensor when the first vibration level is higher than the second vibration level. On the other hand, the computing resource may reduce the sensor weight of the first sensor when the first vibration level is lower than the second vibration level.

According to an embodiment, the computing resource may transmit information about the adjusted sensor weight to the target vehicle. In addition, the computing resource may generate the information about the update of the parameter based on the adjusted sensor weight, and transmit the information about the update of the generated parameter to the target aircraft. For example, computing resources may be updated by sending the modified sensor weights to the controller of the vehicle over the wireless network.

In addition, after the computing resource transmits the adjusted sensor weight to the target vehicle, when the total vibration level of the target vehicle is greater than or equal to a limit, the computing resource generates information on a warning message for parameter tuning, and generates the generated parameter tuning task. Information about the warning message for the carrier may be transmitted to the target vehicle. In this case, the warning message for the parameter tuning operation may be a message for performing the parameter tuning operation through the flight test.

After performing the simulation to change the sensor weight, the computing resource re-analyzes the magnitude of acceleration for each sensor position based on the value of the received data log, and identifies the system if the vibration in each sensor still falls outside the acceptable range. And a FLAG to the controller indicating that the controller tuning operation is required, and the pilot generates a warning message at helicopter startup.

According to an embodiment of the present disclosure, the computing resource may be analyzed by applying updated sensor weights to determine whether the result is similar to the predicted value, and may be reflected in the next weight adjustment process in consideration of the error level of the predicted value. Computing resources monitor vibration data histories for all aircraft managed by the data center or computing resources, so that when a checkpoint arrives, the pilot may transmit information to the aircraft that the checkpoint has arrived. have.

In addition, the computing resources may send occasional checks to the aircraft if there is a sudden change in the vibration data. In addition, computing resources may block access to the data center to prevent the data center from accessing the network during flight operations.
