Problems solved by technology

[0004] In the stage of aircraft requirements, testing and verification are generally completed through pure digital simulation. For the ARINC429 communication protocol, in the HIL test plan, the ARINC429 IO card or simulation card is generally used to realize the communication process. This approach is impractical and expensive during digital simulation

Embodiment Construction

[0037] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0038] refer to figure 2 Shown, the present invention utilizes the application data field of UDP to form the protocol word of ARINC429 for reaching the communication process of emulating ARINC429 on Ethernet, utilizes the source port of UDP, the purpose port to emulate the sending end and the receiving end of representative ARINC429 protocol word, Such as figure 2 and image 3 shown. The present invention utilizes the characteristics of the Ethernet UDP communication protocol to define a set of Ethernet application layer protocols based on the ARINC429 protocol on the application layer. It can achieve multi-channel ARINC429 message sending and receiving on one Ethernet channel.

[0039] The main part of the present invention is to use the UDP communication protocol to define a set of application layer protocols based on the ARINC429...

Abstract

The invention discloses an ARINC429 bus digital simulation communication method based on Ethernet. The ARINC429 bus digital simulation communication method based on Ethernet is characterized by comprising the first step of defining ARINC429 protocol words, the second step of defining an application layer ARINC429 simulation protocol, and the third step of simulating the ARINC429 protocol information transmission on Ethernet by the utilization of the definition in the first step and the second step. Receiving and sending of the ARINC429 information between two devices can be simulated on one Ethernet channel, and the receiving or the sending of the ARINC429 information can be simulated in two directions by the utilization of the duplex characteristic of the Ethernet communication.

Description

technical field [0001] The invention relates to a communication method, in particular to an Ethernet-based ARINC429 bus digital simulation communication method. Background technique [0002] The ARINC429 bus specification is an aviation industry standard specially stipulated for the communication of avionics systems, and communicates in a simplex manner. The HIL verification method is generally used in the aircraft system integration verification, but the pure digital simulation method is generally used in the verification and confirmation stage of the aircraft system requirements. At this time, the A429 bus communication method between the avionics systems needs an effective simulation method instead. , ARINC429 protocol simulation communication based on Ethernet is a very effective choice, it not only has flexible connection and high transmission rate, but also can easily connect digital simulation devices (computers). [0003] Ethernet UDP protocol communication process,...
