Miniature TCAS (Traffic Collision Avoidance System)

Abstract

The invention provides a miniature TCAS (Traffic Collision Avoidance System), which is a miniature multifunctional TCAS realized based on a microprocessor and an FPGA (Field Programmable Gate Array) as well as special software. Four devices of the TCAS, two S-mode responders, a control box and a display of systems of the TCAS II are integrated into a whole, thus a bus is reduced, and the transmission of a large quantity of high-frequency signals among the devices is avoided. The system can be linked with navigation systems (such as devices of Big Dipper, GNSS (Global Navigation Satellite System), GPS (Global Positioning System), inertial navigation, tactical air navigation system and the like) directly, and accurate navigation data are used for replacing or correcting the direction and distance data measured by using the original TCAS II, thus more accurate and reliable avoidance decisions are obtained. The novel TCAS has the advantages of small volume and light weight, and integrates all functions of the four devices of the TCAS II; and the volume and the weight of the novel TCAS are below 1/3 that of the TCAS II.

Description

Technical field [0001] The invention relates to a small airborne collision avoidance system, which belongs to the fields of air traffic management and air traffic safety. Background technique [0002] The anti-collision system on the aircraft, the American aviation system is called the air traffic warning and anti-collision system (hereinafter referred to as TCAS), and the European aviation system is called the airborne collision avoidance system. The meaning and function of the two are the same, and the composition is basically the same. Similar, therefore, the description of the application of the present invention is described with TCAS as the technical background. [0003] After years of development, TCAS system has developed a variety of models, such as: TCAS I, TCAS II, TCAS III, TCAS IV. Among them, TCAS II is the most widely used at present, and the architecture of other higher version models is based on TCAS II, but there are slight differences in functions. [00...

AI Technical Summary

Problems solved by technology

[0006] Through an in-depth analysis of the existing anti-collision system, the main problem is that the realization of the anti-collision function must rely on the cooperation of the TCAS module and the S-mode transponder. However, the two systems are very similar in structure, but they are divided into two different systems. equipment, which will inevitably result in a relatively large volume and weight of the anti-collision system, so it is not suitable for installation on small aircraft with limited internal space, such as military aircraft and unmanned aircraft, etc.
