Problems solved by technology

[0005] Aiming at the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a civil aviation flight telegraph verification system and method based on a cyclic redundancy check algorithm, to solve the problems caused by aviation telecommunications in the prior art during the transmission of air transport industry messages. Network transmission system, sudden interference or human factors cause the problem of "changing characters"; the method of the present invention adds a CRC check algorithm, and the system automatically detects the error code caused by interference during the data transmission process, thereby ensuring the integrity of the data , reduce manual processing, improve the automatic recognition rate of messages, and avoid safety accidents caused by understanding ambiguity

Abstract

The invention discloses a civil aviation flight telegram verification system and method based on a cyclic redundancy check algorithm. The system includes: a message receiving module for receiving civil aviation flight telegrams sent by a telegram relay machine; a message parsing module for receiving The received message is preliminarily parsed to determine whether it is a valid message; the CRC check module, according to whether the message has a CRC code check label, performs CRC code check on the message; the message check module checks the message. The correctness of the message is verified; the manual processing module, the error message that cannot be automatically processed by the message verification module, is processed through the human-machine interface; the message result processing module is used for data processing, and the processing results are generated. , and send the correct command to the receiver at the same time. The method of the invention ensures the integrity of the data, reduces the manual processing, improves the automatic identification rate of the message by increasing the CRC check algorithm, and avoids the occurrence of security accidents due to ambiguity in understanding.

Description

technical field [0001] The invention belongs to the technical field of flight telegram processing of civil aviation air traffic control (ATC), and specifically refers to a civil aviation flight telegram verification system and method based on a cyclic redundancy check (CRC) algorithm. Background technique [0002] With the rapid growth of my country's civil aviation transportation industry in recent years, the increasing air traffic flow has brought enormous pressure and unprecedented challenges to the corresponding air traffic control departments. The air traffic control automation system is a system widely used in the air traffic and management of the aviation sector. The aviation flight telegram is an important data source of the air traffic control automation system and the main information source of the control command. The telegram contains the key data information of aviation flight. , such as flight plans, weather, aeronautical information, etc. These messages are a...
