Embodiment Construction

[0022] The specific implementation manner of the present invention will be described in detail in conjunction with the summary of the invention and the accompanying drawings.

[0023] The working principle of the A / C mode transponder is as follows: figure 1 shown. The antenna receives the 1030MHz inquiry pulse signal, which is added to the pre-filter through the circulator to filter out image interference and other clutter in the L-band. In the receiver, it is mixed with the local 1090MHz oscillation signal to obtain a 60MHz intermediate frequency signal, and then sent to the decoder after signal amplification and band-pass filtering. The decoder identifies the pattern by counting the time interval between pulses and triggers the encoder to generate an identification code or altitude code. The coded pulse train formed by the encoder is added to the modulator, and the modulator controls the transmitter to generate a 1090MHz radio frequency pulse response signal with a power t...

Abstract

The invention discloses an A/C-mode responder system with the anti-human error function. The system comprises three LRUs: a transceiver host, a control box and an omnidirectional antenna. The transceiver host mainly completes processing of a transceiving signal, protocol processing, interface adaptation, and emergency identification and management and is capable of monitoring the system state to identify an external operation so as to select a working mode. The control box is used for completing setting of the system working mode and parameter setting by the flight personnel according to setting permission of opening working modes and parameters of the system and aircraft flight state provided by the transceiver host. The omnidirectional antenna is used for receiving an interrogation signal sent by a ground secondary radar. According to the system, the human operation authority is minimized; for the necessary manual operations, an error-proof operation and anti-error operation design is made for avoiding the false operation and the violation operation, so that the equipment and system failures caused by human factors are reduced effectively and the system redundancy is improved substantially and thus the continuous and effective ground monitoring is supported.

Description

technical field [0001] The invention belongs to the technical field of avionics, and in particular relates to an A / C mode transponder system with the function of preventing human errors. Background technique [0002] The A / C mode transponder is an airborne electronic device that responds to the interrogation signal sent by the interrogator. When inquiring in mode A, the response signal is the aircraft identification code; in inquiring mode C, the response signal is altitude coded information; in addition, it can also actively send out special codes to indicate critical events. [0003] In the civil aviation system, the A / C mode transponder responds to the inquiry signal of the ground secondary radar to realize the effective monitoring of the aircraft. The response signal mainly includes three types: aircraft identification code, altitude and special code. The A / C mode transponder is still the most important monitoring means and method used in the current civil aviation syst...
