Embodiment Construction

[0029] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] The invention discloses a signal processing method for airborne equipment, which specifically includes the following steps:

[0031]When sending a signal: use the ARINC429 interface chip to receive the input signal of the external ARINC429 bus, judge the signal type according to the flag bit of the input signal, and input the signal to the central processing computer, and the central processing computer selects the corresponding central processing unit partition to input according to the signal type The signal is processed, and the processed signal is sent to the FPGA for corresponding encoding, and the message is sent after the encoding is completed;

[0032] When receiving a signal: FPGA receives an external signal, and selects the corresponding decoding program to decode according to the flag bit of the external signal...

Abstract

The invention relates to the technical field of aeronautical communication, and discloses a signal processing method for airborne equipment. The method comprises the following steps: when sending a signal, receiving an external input signal by adopting an interface chip, judging the type of the signal according to the flag bit of the input signal, inputting the signal to a central processing computer, selecting a corresponding central processor partition by the central processing computer to process the input signal, sending the processed signal to an FPGA (Field Programmable Gate Array) for corresponding encoding, and messaging after the encoding operation is finished; during the process of receiving the signal: receiving the external signal by the FPGA, selecting a corresponding decoding program for decoding according to the flag bit of the external signal, inputting the external signal with completion of finishing the decoding operation to the corresponding processor partition of the central processing computer for processing; and after the processing operation is finished, displaying the signal according to the type of the signal or outputting the signal through an ARINC429 interface chip. The invention further discloses a system for the signal processing method. Therefore, the functions of a plurality of systems are finished in one system, thereby reducing the hardware cost.

Description

technical field [0001] The present invention relates to the technical field of airborne equipment signal processing, in particular to an airborne equipment signal processing method and system. Background technique [0002] In order to ensure flight safety, the aircraft needs to receive or send multiple signals during flight. For example, the collision avoidance system receives and sends out warning information, and the transponder generates a response signal according to the identity and position information of the aircraft, and automatically sends the position of the aircraft and other key additional data required by the aircraft at regular intervals. In the prior art, different systems are used to complete the various functions mentioned above. For example, ACAS or TCAS are mostly used in the anti-collision system. Case. The transponder (Transponder: XPDR) needs to compile the transponder code and information such as barometric altitude into a response pulse and send it ...
