Problems solved by technology

The point-to-point communication method cannot meet the self-diagnosis and self-test requirements of aircraft products. It has high requirements for aircraft software and is not universal, and gradually cannot adapt to the development of aircraft systems; the maximum rate of CAN bus communication can only reach 800kbps. Encountered a bottleneck in the process, unable to adapt to the increasingly high demand for guidance and stability closed-loop feedback loop control

Embodiment 1

[0036] see figure 1 As shown, the embodiment of the present invention provides a method for communication between mother and child aircraft based on 1553B bus, including the following steps:

[0037] see figure 2 As shown, the parent aircraft bus subsystem is established according to the 1553B bus protocol, the parent aircraft computer is initialized as the BC node of the parent aircraft bus subsystem, and other stand-alone aircraft and child aircraft of the parent aircraft are initialized as RT nodes of the parent aircraft bus subsystem or BM node;

[0038] see image 3As shown, the sub-aircraft bus subsystem is established according to the 1553B bus protocol, the sub-aircraft computer is initialized as the BC node of the sub-aircraft bus subsystem, and other stand-alone machines of the sub-aircraft are initialized as RTs of the sub-aircraft bus subsystem Node or BM node, at the same time, the sub-aircraft computer is used as the RT node of the bus subsystem of the parent...

Embodiment 2

[0053] The embodiment of the present invention discloses a 1553B bus-based communication system for mother-child aircraft, including:

[0054] The mother aircraft bus subsystem established according to the 1553B bus protocol, the BC node of the mother aircraft bus subsystem is the mother aircraft computer, and the RT node and BM node of the mother aircraft bus subsystem are other stand-alone machines of the mother aircraft;

[0055] The sub-aircraft bus subsystem established according to the 1553B bus protocol, the BC node of the sub-aircraft bus subsystem is the sub-aircraft computer, the RT node and the BM node of the sub-aircraft bus subsystem are other stand-alone machines of the sub-aircraft; while the sub-aircraft The computer also acts as an RT node for the parent aircraft's bus subsystem.

[0056] There is only one set of bus subsystems of the parent aircraft, and one or more sets of bus subsystems of the child aircraft are connected to the bus subsystem of the parent ...

Embodiment 3

[0061] On the basis of embodiment 2, the working process of the embodiment of the present invention is:

[0062] (1) When the sub-aircraft is tested separately, the 1553B bus of the sub-aircraft works alone, the computer of the sub-aircraft acts as a BC node for scheduling, and other stand-alone aircraft (including ground testers) accept scheduling and receive data as RT nodes or BM nodes.

[0063] (2) When the parent aircraft is tested alone, the 1553B bus of the parent aircraft works alone, the computer of the parent aircraft acts as a BC node for scheduling, and other stand-alone aircraft (including the ground measurement, launch and control system) accept scheduling and receive data as RT nodes or BM nodes.

[0064] (3) During the joint ground test of the parent-child aircraft, the computer of the parent aircraft on the 1553B bus of the parent aircraft acts as a BC node for scheduling, and other stand-alone aircraft (including the computers of each child aircraft and the gr...

Abstract

The invention discloses a child and mother aircraft communication method and system based on a 1553B bus, and relates to the technical field of aircraft control systems. The method disclosed by the invention comprises the steps of: establishing a mother aircraft bus sub-system and a child aircraft bus sub-system according to a 1553B bus protocol; initializing a mother aircraft computer to a BC node of the mother aircraft bus sub-system, and initializing other standalones of a mother aircraft to RT nodes or BM nodes of the mother aircraft bus sub-system; initializing a child aircraft computer to a BC node of the child aircraft bus sub-system, and simultaneously, taking the child aircraft computer as the RT node of the mother aircraft bus sub-system; and initializing other standalones of a child aircraft to RT nodes or BM nodes of the child aircraft bus sub-system. Only a set of mother aircraft bus sub-system is arranged; one or more sets of child aircraft bus sub-systems are arranged, and hooked onto the mother aircraft bus sub-system at the same time; therefore, a star topological network is formed; and thus, the ground test reliability is ensured.

Description

technical field [0001] The present invention relates to the technical field of aircraft control systems, in particular to a method and system for communication between mother and child aircraft based on 1553B bus. Background technique [0002] The characteristics of the control system design of the child-parent aircraft are that the child-aircraft and the parent aircraft are highly independent, the relationship between the system and the subsystem is complex, the control timing is strict, and the reliability is high. [0003] Modern aircraft systems are required to implement self-diagnosis and self-test functions to meet the needs of users for easy maintenance and easy use. The existing domestic aircraft communication methods include point-to-point synchronous serial communication, asynchronous serial communication, and multi-master control CAN bus communication. The point-to-point communication method cannot meet the self-diagnosis and self-test requirements of aircraft pr...
