Problems solved by technology

[0003] In practical applications, the terminal information automatic broadcasting system needs to obtain weather message data from the civil aviation automatic reporting system, and the civil aviation automatic reporting system meteorological data is provided by the meteorological automatic observation system; therefore, the delay time of real-time meteorological data broadcasting is increased , and when the automatic reporting system fails, the terminal information automatic broadcasting system will not be able to receive real-time meteorological data, which will cause problems such as untimely broadcasting of meteorological information and inaccurate current broadcasting

Embodiment 1

[0044] The method for shortening the delay and improving the accuracy of the broadcast data of the terminal information in this embodiment includes:

[0045] Receive METAR and SPECI weather messages from the civil aviation AFTN telegraph network, save and query the data of METAR and SPECI weather messages, and collect runway status information;

[0046] Analyze METAR and SPECI weather messages according to civil aviation regulations;

[0047] Through the data control processing module, compare whether the meteorological data is later than the current broadcast meteorological data release time, if it is later, generate new Chinese and English broadcast text data, otherwise discard;

[0048] The received civil aviation meteorological telegrams METAR and SPECI include the data release time and are a must. The received custom protocol data of the self-viewing system also include the data release time and are also a must. If not included, it will be displayed during data analysis. ...

Embodiment 2

[0059] Terminal Intelligence reduces latency and improves broadcast data accuracy systems, including:

[0060] The message receiving module mainly receives METAR and SPECI weather messages from the civil aviation AFTN telegraph network;

[0061] The message analysis module is mainly used to analyze METAR and SPECI weather messages according to civil aviation regulations;

[0062] Message access module, mainly to save and query METAR and SPECI weather message data;

[0063] Other information modules mainly collect runway status information;

[0064] The artificial insertion module is mainly an input interface provided for fusing artificially inserted text data information.

[0065] Speech synthesis module, which mainly converts broadcast text data into speech;

[0066] The voice playback module mainly plays the voice data generated by the voice synthesis module in a round-robin manner;

[0067] The meteorological self-observation data receiving module mainly receives the or...

Abstract

The invention relates to a method and system for shortening navigation station information delay and improving broadcast data accuracy. The method comprises the steps: receiving METAR and SPECI meteorological statement from civil aviation AFTN telegram network, storing and inquiring METAR and SPECI meteorological statement data and collecting track condition information; analyzing the METAR and SPECI meteorological statement according to civil aviation regulations; converting broadcasted text data into voice; broadcasting voice data generated by a voice synthesis module in a rotary training mode; receiving original data of a meteorological self-observing system; analyzing received original data according to a data protocol of meteorological self-observing system; fusing meteorological statement data, meteorological self-observing data, other information data and manual inter-cut data to finally generate broadcastable test data.

Description

technical field [0001] The invention relates to the technology in the field of air traffic control, in particular to a method and a system for shortening the delay of broadcast data and improving the accuracy of broadcast data in an automatic broadcasting system of terminal information. Background technique [0002] The full broadcasting system in civil aviation is called the terminal information automatic broadcasting system. The system automatically and continuously broadcasts information services at the airport, usually on a separate radio frequency, including major flight-related information, such as weather and available runways. , barometric pressure and altimeter setting value and other information; the main source of information is the data of the civil aviation automatic transmission system. By receiving the weather message data of the civil aviation automatic reporting system, it is parsed into Chinese and English data that can be broadcast by the broadcast system ...
