Wireless communication device and wireless communication set

Abstract

The embodiment of the invention relates to a wireless communication device. The wireless communication device comprises a photoelectric converter, a frequency generator, a modulator, a power amplifierand an antenna; the photoelectric converter receives a shunting light signal sent by an optical splitter, converting the shunting light signal into a first electrical signal and sending the first electrical signal to the modulator; the frequency generator generates a frequency signal and sends the first electric signal to the modulator; the modulator modulates the first electric signal into a frequency signal to generate a first driving signal, and sends the first driving signal to the power amplifier; the power amplifier amplifies the first driving signal to generate an amplified first driving signal; the antenna sends a first pulse signal according to the amplified first driving signal, and the first pulse signal is used for being received by a wireless signal transceiving device. According to the wireless communication device, the millimeter wave communication technology and the optical communication technology are combined, and a special communication protocol is used for achieving high-capacity and high-reliability data communication of a train under a high-speed moving condition.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a wireless communication device and a wireless communication set. Background technique [0002] So far, the purpose of all mobile communication systems is to solve personal communication. Therefore, from the first generation mobile communication system to the current 5G mobile communication system, all the development of mobile communication technology is to improve the quality of personal communication. Therefore, it is unrealistic to try to solve the vehicle-to-ground communication of high-speed trains under wide-area conditions based on the existing mobile communication technology or existing infrastructure. In fact, GSM-R, which evolved from GSM technology, is increasingly unable to meet the increasingly urgent information and intelligent vehicle-to-ground communication needs of high-speed railway transportation, and there is no effective progress in this techno...

Problems solved by technology

Long-distance wireless communication due to climate change, such as rain, snow, fog and other harsh weather phenomena will not only reduce the quality of wireless communication, but even interrupt communication, so that wireless communication will lose the important support means of high-speed rail informatization and intelligence will directly lead to the failure of high-speed rail informatization and intelligence

[0006] Similarly, although wireless optical communication is not affected by the Doppler effect, it has too high requirements on meteorological conditions and the high complexity of the system. At present, it is not possible to see the possibility of this technology being applied to high-speed rail communication, while satellite communication In addition to the limitation of communication bandwidth, weak satellite signals and too many railway tunnels in high-latitude areas are also the main reasons that limit the application of satellite communication in high-speed rail vehicle-ground communication
