摘要
针对由于传输差错及人为因素引起的报文准确性和完整性问题,本文介绍了ACARS报文的种类及其基本结构；提出了参数辨识技术,它包括报文数据的预处理、译码和校验三部分。实验结果证明,该技术提高了ACARS报文的正确识别率,具有维护简单、扩充方便灵活的优点,对空地数据链技术在民航的有效应用起到积极作用。
Aiming at the problems of inexactitude and disintegrality of message due to transmission errors and human factors, the basic structure and the type of ACARS message are described; and also a parameter identifying technology is set forward in this paper. The technology as mentioned above includes message data preprocessing, decoding and checking. The experimental results show the technology improved ACARS message recognizing rate and has the advantage of simplifying maintenance and facilitating expansion. It would be helpful for actively promoting the application of air-ground data link technology to the commercial aviation.
