Problems solved by technology

However, the existing telegram analysis methods often analyze a single telegram type, and the types of telegrams to be parsed are limited, which may make it impossible to process some infrequently used but important telegram messages; moreover, the existing telegram analysis methods use card position analysis For some non-standard telegrams, it is impossible to analyze them. For example, when the telegram staff accidentally reversed the order of several telegram elements when sending telegrams, the card position analysis method cannot be used to resolve these sequences. Standardized message elements, so when parsing telegrams, some messages cannot be parsed
[0005] To sum up, the existing telegram analysis methods are not comprehensive enough for telegram text analysis

Abstract

The invention discloses a telegram analyzing method and device. The telegram analyzing method comprises the steps that after the type of a received telegram is determined, telegram text factors recorded in advance under the type of the telegram are found from a telegram text factor data list; for each telegram text factor under the type of the telegram, a regular expression library is searched for a regular expression corresponding to the telegram text factor under the type of the telegram; for each found regular expression, matching is conducted on the telegram text of the received telegram and the regular expression, and a telegram text code obtained through matching is used as an analysis result of the telegram text factor corresponding to the regular expression. Due to the fact that matching is conducted on the telegram text factors in the telegram text of the telegram and the regular expressions, the position sequence relation between the position of a certain telegram text factor in the telegram text and other telegram text factors does not need to be considered, it is only required that the telegram text factor meets the filtering logic of the corresponding regular expression, and the telegram can be more compressively analyzed.

Description

technical field [0001] The invention relates to the technical field of telegram analysis, in particular to a telegram analysis method and device. Background technique [0002] The telegraph was one of the earliest reliable means of instant long-distance communication. At present, the civil aviation industry generally adopts a fast and accurate method such as the telegraph to obtain relevant flight, weather and business information. Among them, civil aviation flight dynamic fixed-format telegrams are divided into two formats: AFTN (aeronautical fixed telecommunications network, aviation fixed telecommunications network) and SITA (societe internationale telecommunications deaeronactiquas, international aviation telecommunications company). AFTN telegrams are used by the air traffic control department, and undertake the information exchange of domestic and international air traffic management, flight dynamics, navigation weather and business affairs processing of relevant depa...
