Problems solved by technology

The first is to set up a separate backup system, which has better functional independence. The disadvantage is that it relies too much on the back-end drive control unit, which requires high reliability of the drive control unit and complex switching control logic. The current drive control unit technology It is not mature enough, which introduces new risks to the normal operation of the system; the coupling degree of the second method is too high, if the interface board inside the computer fails, the backup command cannot be transmitted to the back-end actuator, and the backup function is lost

Abstract

The invention discloses a backup control system and belongs to the technical field of aviation control. The system comprises a driver plate arranged in a computer and a backup control board that sends a backup instruction to the driver plate; the computer can generate a control instruction of controlling an airplane to run normally; the control instruction is sent to an execution mechanism through an interface board; and the execution mechanism controls each part of the airplane to perform motion. Through a method for physically isolating the backup control system from a normal control system, the influence on a backup channel after a fault occurs to the computer is reduced as far as possible, and after a normal channel of the computer has a fault, the backup channel still can work normally, so that a backup function of the system is realized.

Description

technical field [0001] The invention belongs to the technical field of aviation control, and in particular relates to a backup control system. Background technique [0002] The backup control system is the backup control of aviation flight equipment. When the normal control instructions of the aircraft cannot be effectively transmitted to the actuator, the backup control system is used to complete the input of the aircraft's instructions, so as to control the aircraft to continue to complete the flight mission. [0003] In the prior art, the backup control system is generally implemented in two ways, one is to set up a separate hardware system to achieve, for example, the instructions of the backup control board are directly connected to the drive control unit, and the drive control unit receives the backup command Finally, the manual switch from normal to backup should be realized. In addition, in the case of all failures of the normal control system, it should be automatic...
