Problems solved by technology

Due to the large differences in the 1553B bus data communication protocols between different types of tasks, and the variety of message transmission methods, the 1553B bus chip can be configured into different working modes such as BC and RT, as well as the characteristics of BC active and RT passive. The generalization and transparent design of the 1553B bus driver software bring many difficulties

Abstract

The present invention provides a 1553B bus data communication method and system, which is applied in an embedded operating system, and the embedded operating system is loaded with a driver program and an application program of a bus controller BC; the method includes: Step S1: All data packets are divided into single messages of no more than 32 words; Step S2: BC sends a single message to RT according to the rotating RT subaddress, and agrees on the data transmission protocol in the message content; Step S3: RT follows the single message interruption method, The single messages transmitted by each RT sub-address are sequentially received, and protocol analysis is performed on the single messages. The present invention simplifies the interface between the 1553B bus application program and the driver program, realizes the general design of the 1553B bus driver software, and reduces the development difficulty of the 1553B bus application program through the transparent and standardized design of the driver software to the application software. Improve software development efficiency.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a 1553B bus data communication method and system. Background technique [0002] MIL-STD-1553B (aircraft internal time-division command / response multiplex data bus) is a digital time-division serial data bus with high reliability, strong anti-interference ability, flexibility, high speed, expansion and maintenance It is widely used in the design of communication networks of domestic and foreign aviation and aerospace electronic systems because of its simplicity and simplicity. The transmission protocol of the 1553B bus is command / response mode, and the smallest unit of data transmission is "bus message". All message transmissions are issued by BC (bus controller) and responded by RT (remote terminal). [0003] At present, aviation and aerospace electronic products are gradually developing towards modularization and productization, especially the development of integ...
