Abstract

The invention is applicable to the field of data transmission, and provides a data transmission control method, a data transmission control module and a terminal for high and low speed coexisting bus terminals. The method comprises the following steps of: judging transmission modes corresponding to protocol words obtained by performing GJB289A protocol processing on a high speed interface component and a low speed interface component according to judgment conditions of a normal transmission mode; and controlling the high speed interface component or the low speed interface component to perform transmission by using a double-bus mode or single-bus mode according to bus operating mode information, received channel failure feedback information and the transmission mode corresponding to each protocol word. In the embodiment of the invention, the data transmission control method for the high and low speed coexisting bus terminals is realized, so the problem of data transmission of the high and low speed coexisting bus terminals is solved, the compatibility with the conventional GJB289A bus communication system is ensured and the transmission of the conventional communication system is not influenced.

Description

Technical field [0001] The invention belongs to the field of data transmission, and in particular relates to a high- and low-speed coexistence bus terminal data transmission control method, a control module and a terminal. Background technique [0002] At present, the aviation bus protocol formulated by our country is GJB289A. The GJB289A bus protocol is a data communication standard widely used in military aircraft, high-precision guided military weapons, ground military tools and naval vessels. The GJB289A bus protocol is mainly used in the following occasions: [0003] (1) Information needs to be transmitted through coaxial cables between bus terminals; [0004] (2) The electrical parameters of all bus terminal interfaces are unified standards; [0005] (3) Information is required to be transmitted in a reliable, deterministic, command / response manner. [0006] Due to the limitations of reliability, electrical interface, hard disk capacity and other factors, GJB289A defines the tr...
