Embodiment Construction

[0018] The invention adopts the main structure of FPGA+DPS and matches other peripheral devices to realize the purpose of integrating the S mode transponder controller circuit into the TCAS controller. The integrated system structure is as follows figure 2 shown.

[0019] In the original TCAS system, the TCAS controller generally uses a 32-bit processor with a working frequency of 16MHz, and the controller of the S-mode transponder is generally a 51 single-chip microcomputer with a working frequency of 12MHz. Therefore, we use a 32-bit processor, and the working frequency can reach More than 200MHz can fully meet the processing speed requirements.

[0020] After the integration, we manage the ARINC429 bus interface in a unified manner, and reassign labels to the duplicate items in the LABEL item used to represent the data type, so that there is no need for communication between the TCAS and the S-mode transponder, and the peripheral between the two Devices are also managed ...

Abstract

The invention relates to a method for integrating a TCAS (Traffic Collision Avoidance System) controller and an S-mode controller. Aiming at the defect of large system volume caused by the separation of the original TCAS controller and S-mode controller, the method adopts a DSP (Digital Signal Processor) + FPGA (Field Programmable Gate Array) architecture, and researches the problem of integration of the TCAS controller and S-mode responder controller in the aspects of signal interfaces, system structure, processing capacity and system functions. No signal collision is produced in the integrated system; the processor has the advantages of stronger functions and higher efficiency; and the implementation method of the system functions remains the same on the whole, but part of functions should be adjusted due to the change of the structure. The interfaces, structure, and allocation and realization of functions of the integrated controller are illustrated.

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 currently the most widely used. It can provide aircraft pilots with traffic reminders (TA) that display information such as relative altitude, distance, azimut...
