[0075] like figure 2 As shown, in the first embodiment of the present application, the redundancy synchronization control method of the present application includes the following steps:

[0076] Step S110, receiving the first redundancy data sent by the first flight computer.

[0077] In this embodiment, in order to solve the problem that the redundancy data between different flight computers cannot be synchronized when the synchronization rhythm is inconsistent, the present application sets a redundancy synchronization module on each flight computer, so that the redundancy synchronization module can be based on the first The redundancy data of the flight computer and the state of the data determine whether the calculation is performed with the first redundancy data of the first flight computer or the second redundancy data of the second flight computer to improve the accuracy of the synchronization data.

[0078] In this embodiment, the basic function of redundancy manageme...

Abstract

The invention discloses a redundancy synchronization control method, a flight controller and a storage medium, and is applied to the technical field of flight controllers. The method comprises the following steps: receiving first redundancy data sent by a first flight computer; when the first redundancy data is different from second redundancy data in a synchronization list of a second flight computer, acquiring the state of the first redundancy data; and when the state of the first redundancy data is a synchronous state, the first redundancy data is sent to the second flight computer, so that the second flight computer adopts the first redundancy data to carry out operation. Redundancy data between different flight computers can be synchronized, and the accuracy of data synchronization is improved.

Description

technical field [0001] The present application relates to the technical field of flight controllers, and in particular, to a redundancy synchronization control method, a flight controller and a storage medium. Background technique [0002] The flight control system is an important part of the aircraft, and its system configuration plays a decisive role in the performance and safety of the aircraft. At present, the redundancy configuration of the flight control system is controlled by a dual-redundancy or triple-redundancy computer, so that when the main flight computer fails, other slave flight computers can replace the main flight computer to continue to perform follow-up work. The operating states of the flight computer and the slave flight computer need to be kept synchronized. For example, when the master flight computer is executing content A, the slave flight computer should also be executing content A, so that when the master flight computer fails while executing cont...
