Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing airborne collision avoidance system simulator self-inspection circuit needs to be equipped with two sets of four frequency sources, resulting in complicated equipment self-inspection circuits, many components, and poor reliability. The single-frequency self-test method used in the airborne collision avoidance system simulator that can complete the self-test of the interrogation module and the response module by setting two frequency sources

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as Figure 1-4 shown.

[0019] A single-frequency self-inspection method for an airborne collision avoidance system (TCAS for short) simulator. First, an inquiry module that only generates a frequency of 1030MHz and a response module that generates a frequency of 1090MHz are respectively set up, and the coupler and the inquiry module and the response module are respectively set. After being connected by a coupler and a radio frequency cable, they are mutually self-test sources, thereby saving one 1090MHz frequency source in the inquiry module and one 1030MHz frequency source in the response module, and simplifying the self-test circuit. The block diagram of the self-test circuit described in the figure 1 shown in , while the structure of the airborne collision avoidance system simulator can be found in Figure 4 . Depend on figure 1...

Abstract

The invention discloses a self-detection method for a unifrequency source of a traffic collision avoidance system simulator, which is characterized in that a query module capable of generating a frequency of 1030MHz and a response module capable of generating a frequency of 1090MHz are respectively arranged, and the query module and the response module are used as respective self-detection sources after being connected by a coupler and a radio frequency cable, thereby realizing that one 1090-MHz frequency source is omitted in the query module, one 1030-MHz frequency source is omitted in the response module, and the aim of simplifying a self-detection circuit is achieved. The invention reduces equipment at a self-detection part of the traffic collision avoidance system (TCAS) simulator, simplifies the self-detection circuit, is suitable for self-detection of general civil aviation query-response equipment and similar occasions and has the advantages of simpleness, reliability and the like.

Description

technical field [0001] The invention relates to an aircraft safety detection device, in particular to a simulator for testing whether an airborne collision avoidance system works normally, specifically a single-frequency self-inspection device used in an airborne collision avoidance system simulator method. Background technique [0002] At present, in order to prevent the aircraft from colliding with each other in the air, most of the civil aviation airliners and some military aircraft have installed the Airborne Collision Avoidance System (TCAS) on the aircraft. [0003] TCAS and airborne transponders need regular testing and maintenance. In order to facilitate testing and maintenance, a TCAS simulator has been developed to provide radio frequency excitation signals to airborne TCAS and transponders to test their receiving functions; at the same time, TCAS simulates The transmitter can receive and decode the radio frequency signals transmitted by the TCAS and the airborne ...
