Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] An embodiment of a dual-channel redundant CANFD wireless optical transmission system of the present invention, such as Figure 1 to Figure 4 Take the signal transmission between the rocket stages as an example to illustrate. The rocket is divided into three stages, namely the first stage of the rocket, the second stage of the rocket, and the third stage of the rocket. The three-stage rocket transmits the signal through the dual ...

Abstract

The invention relates to a double-channel redundancy CANFD wireless optical transmission system, which comprises a double-channel redundancy CANFD bus, and a plurality of CANFD bus devices are connected into the double-channel redundancy CANFD bus. The two-way redundancy CANFD bus comprises at least two parts, in the two adjacent parts of the two-way redundancy CANFD bus, one part of the two-way redundancy CANFD bus is connected to the wireless light emitting module, the other part of the two-way redundancy CANFD bus is connected to the wireless light receiving module, the wireless light emitting module converts a two-way redundancy CANFD electric signal into a two-way redundancy wireless light signal and emits the two-way redundancy wireless light signal, and the wireless light receiving module receives the two-way redundancy wireless light signal. The corresponding wireless light receiving module receives the double-channel redundant wireless light signals and then converts the double-channel redundant wireless light signals into double-channel redundant CANFD electric signals. Information transmission is carried out among the devices through a double-channel redundant CANFD bus, so that higher-rate transmission and longer effective load can be realized; for devices needing to be separated, such as a rocket, wireless transmission is carried out between rocket stages through the wireless light emitting module and the wireless light receiving module, and rocket stage installation and separation are easy to achieve.

Description

technical field [0001] The invention relates to the technical field of wireless optical transmission, in particular to a dual-channel redundant CANFD wireless optical transmission system. Background technique [0002] With the maturity and development of information technology, the degree of digital informatization in aviation, aerospace, vehicles, rockets, missiles and other military fields has been continuously strengthened. The transmission rate of CAN bus has approached its bandwidth limit, and CAN FD (Flexible Date Rate) is compatible with CAN bus devices. , which can achieve higher transmission rates and longer payloads. The traditional CAN bus speed can only reach 1Mb / s, and each frame has 8 bytes of data, while the CANFD speed can reach 10Mb / s, and each frame can include 64 bytes of data. At present, the communication between the rocket stages or the compartments in the bomb is wired interconnection. During assembly, the cables between the rocket stages or the modul...
