Abstract

The invention discloses a method for solving the race condition in the ARINC661 specification. The method includes: CDS maintains a lock for each interactive component in the aircraft cockpit display and control system; the lock request and release based on UA ​​or CDS send Request, CDS can use the lock to lock and release the interactive component; when the UA enables the lock to lock the interactive component, the UA can set the internal state of the component until the UA releases the lock; when the CDS enables the lock to When the interactive component is locked, CDS can set the internal state of the component until the CDS releases the lock; UA is the user application program, and CDS is the aircraft cockpit display and control system. At the same time, the lock can only be based on the UA or CDS. One sent request to operate; it solves the problem that the existing solutions are not universal, and only reduces the probability of race conditions, and realizes the technical effect of fundamentally solving the race conditions.

Description

technical field [0001] The invention relates to the technical field of avionics, in particular to a method for solving the race condition in the ARINC661 specification. Background technique [0002] With the rapid development of electronic technology in the field of aviation, the degree of integration of avionics and the requirements for human-computer interaction are getting higher and higher, and the development of interactive aircraft cockpit display and control systems is also becoming more difficult. Due to the lack of industry standards, the interfaces of avionics devices produced by different equipment manufacturers are different, which brings inconvenience to the development of aircraft cockpit display systems. The ARINC 661 specification (Cockpit Display and Control System and User System Interface Protocol) was created to solve the long-standing problem of how to quickly develop display and control systems that can be replaced and used together. The ARINC 661 spec...
