Problems solved by technology

Relevant foreign agencies, including FAA and EUROCONTROL, have also formulated similar test and evaluation indicators. However, according to the current investigation of the system used by my country's military and civil aviation control centers, these indicators cannot fully reflect the specific situation of the short-term conflict warning function. The short-term conflict warning system that has passed the certification test...

Embodiment Construction

[0025] In the specific implementation process of functional evaluation, evaluation test cases should be formulated according to the basic functional points. For each function point, in the evaluation test case, the environment configuration, operation steps, expected results and real results are given, and the expected results are checked with the real results. When the two are consistent, it has a corresponding function, otherwise it is regarded as a corresponding function Flawed.

[0026] In the specific implementation process of performance evaluation, the first three alarm indicators are easy to calculate. For the improper alarm rate proposed in this scheme, it is necessary to define the first problem encountered in the calculation of the improper alarm rate: the two parameters of Inapp and Alert per unit time identification problem. Combining the actual application and the working situation of the controller, we give the following identification rules:

[0027] Inapp's ...

Abstract

The invention relates to an evaluation and test method for the short term collision alert in an air traffic control automation system. The method comprises the following steps: defining the function evaluation indexes of the short term collision alert such as an alert delay time, a missed alert rate, a false alert rate and an improper alert rate; seeing the calculation formula of the improper alert rate on the upper right, wherein Inapp is set as the number of alerts which are reported by a short term collision alert functional function in the automation system and are determined redundant or improper by a controller within unit time, and Alert is set as the number of alerts which are reported by the short term collision alert functional function in the automation system and are determined correct by the controller within unit time; and in the test and evaluation period, selecting 24 hours or other proper intervals as the unit time. The method adds the evaluation index of 'improper alert rate' based on the prior evaluation method, thereby avoiding the situation that the prior index test system reports a large number of non-true alerts in the practical work and consequently influences the work of the controller.

Description

technical field [0001] The present invention generally relates to an air traffic control (ATC) automation system, and in particular relates to evaluation indexes involved and related testing techniques and method evaluation technical schemes when performing system testing and evaluation on the short-term conflict warning function of the air traffic control automation system. Background technique [0002] In the modern air traffic control center system, the short-term conflict warning is a very important function of the air traffic control automation system [1, 2]. When the horizontal interval and vertical interval between track pairs are less than or will be less than the set parameter value at the same time within the set alarm time, the system will generate an alarm or early warning to prompt the controller to facilitate flight separation Therefore, the stability and reliability of this function is very critical. It plays an important role in ensuring the order of air traf...
