Problems solved by technology

The existing dual-redundancy flight control computer lacks a perfect synchronization mechanism, and usually only rigidly adopts clock synchronization, which brings a large resource consumption to the flight control calculation. In addition, clock synchronization requires special hardware support, and the instantaneous Faults are prone to common errors. Affected by facto...

Abstract

The invention provides a dual-redundancy flight control computer and a redundancy management method, and belongs to the technical field of flight control. The dual-redundancy flight control computer comprises a host machine and an auxiliary machine which are similar in redundancy and perform hotbackup, and a communication module, a fault detection module and an arbitration switching circuit module; the redundancy management method comprises task synchronization processing based on a comparison point and fault detection and fault tolerance processing based on a cross comparison method, and by adopting the technical scheme, the reliability of the unmanned aerial vehicle system can be effectively improved, and the unmanned aerial vehicle can be effectively switched to the standby machine after the host has a fault, so that the unmanned aerial vehicle restores normal work and continues to complete the task.

Description

technical field [0001] The invention belongs to the technical field of flight control, and relates to a dual-redundancy flight control computer and a redundancy management method, which are used to improve the reliability level of the flight process of an unmanned aerial vehicle. Background technique [0002] At present, most of the existing UAVs in our country adopt single-loop single-redundancy configuration, but the flight control computer in the UAV system fails or fails, not only the flight task cannot be completed, but even the entire UAV will crash. It will cause damage to ground facilities and personnel. The use of modern unmanned aerial vehicles is increasing day by day. In order to make it better complete the task, it is necessary to ensure the reliability of the unmanned aerial vehicle system. Redundancy technology is an effective method to improve the reliability of the unmanned aerial vehicle system. The existing dual-redundancy flight control computer lacks a ...
