Problems solved by technology

However, these special-purpose test instruments are designed as discrete devices, and their main design purpose is not to be integrated into a system, and as far as the instrument itself is concerned, its software processing and user interface are fixed, and can only be used when the manufacturer chooses to update. Updates, and how they are updated, are at the option of the manufacturer, so it is impossible for users to make measurements with these instruments that are not included in their feature list

Abstract

The invention discloses an airborne collision avoidance system (ACAS) tester and a testing method. The tester comprises a signal processing module, a testing ACAS host radio frequency module, a testing S-mode responder radio frequency module and an interface extension, wherein the signal processing module comprises a microprocessor, an FPGA (Field Programmable Gate Array), a signal driving and isolating circuit, a configuration chip and a voltage conversion circuit. The signal processing module accomplishes coding of a transmitting-receiving host inquiry signal of an ACAS, analyzes an S-mode protocol, judges an inquiry format, codes according to an inquiry mode, generates a responding signal, generates an A / C / S-mode inquiry signal for an S-mode responder of the ACAS, codes the responding signal, analyzes the S-mode protocol, and obtains the height and identity data (an S-mode address) of the S-mode responder, and requirements on functions such as blank pipe response, air traffic alarm, ADS-B OUT (Automatic Dependent Surveillance Broadcast Out) of the ACAS tester are met.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to an airborne anti-collision system tester and a test method. Background technique [0002] Airborne anti-collision equipment can be installed on civil aviation aircraft, military transport aircraft, bombers and special aircraft platforms. It is mainly used to prevent dangerous approach and collision accidents in the air, and provide protection for the flight safety of aircraft. [0003] At present, the development of infield detectors for airborne anti-collision equipment can adopt discrete instrument methods and virtual instrument methods. In the traditional discrete instrument method, all discrete components are placed in the same chassis, and the control of the test is realized through GPIB (General-Purpose Interface Bus), USB or LAN. However, these special-purpose test instruments are designed as discrete devices, and their main design purpose is not to be integrated into a s...
