According to the high-throughput wireless data transmission method in the embodiment, the number of data interaction paths of the front end and the rear end of the test and control is up to 8, high reliability of data transmission of the front end and the rear end can be ensured, data interaction can be completed through any path, and even if any transmission link is out of work due to a problem, data interaction of front end equipment and rear end equipment can be normally completed, and the reliability is extremely high.
The high-throughput wireless data transmission system and the high-throughput wireless data transmission method have the advantages that the reliability of front-end and rear-end data transmission is greatly improved, and the system adaptability is high. Insufficient transmission field resources require a solution for providing reliable front-end and back-end data interaction for offshore transmission, and high-reliability transmission can be realized without arranging optical fibers.
The data interaction links at the front end and the rear end of the test and control are 8 ways, and the system is strong in robustness and extremely high in reliability. The system overcomes the severe environments of marine emission such as ship jolt, drift and the like, is more reliable and has strong adaptability compared with the common wireless detection and control system, and can work in different scenes.
The omnidirectional antenna can effectively ensure the data interaction of the front end and the rear end through the lifting rod at a higher position, the communication rate of the high-low frequency broadband equipment reaches 10Mbps, and the high-flux data transmission is realized.
The scheme of the invention is designed for a marine launching scene of a spacecraft, but when the spacecraft is launched on land, the weapon of other spacecrafts such as a carrier rocket, a missile and the like needs to be launched on site rapidly, and when the front end and the rear end are inconvenient to lay optical fibers, the system can be used, so that the reliability is high and the adaptability is strong.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
