Description

technical field [0001] The invention belongs to the field of electronic communication, in particular to a DSP-based electronic communication system. Background technique [0002] Avionics integration technology is an emerging technical field. It uses computer technology, digital communication and processing technology, and local network technology to integrate dense avionics subsystems together, so that they can meet the real-time requirements of each subsystem function. , and achieve the purpose of information sharing and functional integration of various systems through information cross-linking. The realization of information sharing and functional integration of various avionics systems is accomplished through the data communication of the serial bus. The ARINC429 bus is one of the commonly used avionics buses at present. The information exchange between many electronic devices on the aircraft adopts the ARINC429 serial bus standard. The data bus interface developed in...

AI Technical Summary

Problems solved by technology

The data bus interface developed in the early stage in China is limited by technical conditions, the reliability of communication cannot be guaranteed, and the hardware circuit is relatively complicated

Most of the current ARINC429 data bus interfaces use single-chip microcomputers as controllers. Due to the long instruction cycle, the data transmission speed is limited and cannot meet the real-time requirements.
