Abstract

The invention discloses a PCI integrated circuit board device used for ARINC429, mainly comprising an FPGA module, an ARINC429 interface chip, two ARINC429 protocol processing chips, two ARINC429 signal output linear drive chips and a power switching circuit. The FPGA chip is used for realizing PCI interface protocol and completing information interaction and control of a host computer and the board; the FPGA chip executes instruction of the host computer, initializes the ARINC429 interface chip and realizes control and caching of sending and receiving data to realize independent four receiving and two sending function and data sending rate adjustable function. The invention is flexible in configuration, the sending rate is adjustable and is wide in adjustable range, circuit construction is simple, processing cost of the circuit board is low, and different requirements of ARINC429 communication can be completed only by modifying FPGA software without changing hardware, thus the invention has strong commonality and flexibility.

Description

technical field [0001] The invention relates to a PCI board device for ARINC429 communication, which belongs to the communication field. Background technique [0002] ARINC429 digital information transmission specification is one of the commonly used data information transmission standards between airborne equipment, and it is widely used in my country's aviation industry. In modern aircraft, a large amount of information is transmitted at high speed between systems and systems, and between systems and components. At present, a considerable number of aircraft data communications use the onboard ARINC429 data bus. The PCI bus is a high-speed synchronous bus with a bus width of 32 bits, a working frequency of 33 MHz, and a maximum transmission rate of 132 Mbyte / s. Therefore, using the PCI interface to realize ARINC429 communication in the test system has strong flexibility and broad application prospects. [0003] The existing ARINC429 communication board mostly uses a dedica...
