A Method of Constructing and Fault Tolerance of Pre-sequence Flights

Abstract

The invention discloses a method of construction and fault tolerance of front and back flights. The method comprises following steps of step 1, arranging flights in a real-time and orderly manner: according to real-time changing conditions of the flights, carrying out time normalization on the flights with the same flight number according to time zones, actual departure time, estimated departure time and planned departure time, and according to the normalized time, carrying out ascending ranking; step 2, constructing a bidirectional chain table: according to the ordered flight data, firstly filtering all non-stop flights, and sequentially adding the flights into the chain table so as to construct a front and back flight bidirectional chain table in the region communication state between local parts; and step 3, error redundancy of access: searching the front flights according to four conditions: flight numbers, departure places, destinations and departure time. According to the invention, a problem of obstructed flight chain tables caused by errors or missing of related data of flight numbers and time of certain flight data.

Description

technical field

[0001] The invention relates to a method for constructing and fault-tolerant flights, belonging to the technical field of civil aviation information services. Background technique

[0002] The flight delay directly affects people's daily travel, and the delay of the previous flight is a key factor of the delay itself. Next, we find a relationship between flights according to our own method. This relationship is called the previous flight. Sequential flight list.

[0003] A batch of flight data can be connected in series according to key data items such as aircraft number, time, departure place, and destination, and a linked list can be constructed, that is, the previous flight list, but in reality, due to the aircraft number, time and other related data of some flight data The error or absence of the flight link list will not be smooth. Therefore, it is necessary to provide a method of constructing and fault-tolerant flights in order to solve the above probl...
