Abstract

The invention brings forward a real-time transmission method of long-distance and high-throughput data. The method comprises the following steps: signal source data are classified on the basis of data types, and the various classified data are respectively sent to corresponding processing channels; then the data are sent to an FPGA control unit to process; then the data are sent to a data conversion module to perform digital-to-analog conversion; then the data are sent to an I/Q modulation module to perform frequency adjustment and then frequency-mixed with a local oscillator signal so that a high-frequency data signal with adjustable frequency is formed; then noise inhibition processing is performed; and then power amplification is performed and finally the signal is sent out via an antenna. Beneficial effects of the real-time transmission method are that: real-time and long-distance transmission of high-resolution images, videos and data can be simply and conveniently realized without satellites so that the real-time transmission method is small in system delay, high in efficiency and low in cost. A requirement of abrupt incidents can be handled.

Description

technical field [0001] The invention relates to the technical field of wireless data transmission, in particular to a real-time transmission method of long-distance high-throughput data. Background technique [0002] At present, civilian products generally use wifi technology for image transmission, while military products generally use satellites to transmit images. Wifi is generally suitable for the transmission of short-distance ordinary pictures, but not for high-altitude detection and high-resolution image transmission. Although satellite transmission pictures can transmit long-distance high-resolution images, they need to align the antenna before transmission, and the portability and mobility are not good, so they cannot cope with sudden long-distance picture transmission tasks. [0003] Therefore, in response to sudden high-altitude, long-distance, and high-resolution image transmission events, there is currently no convenient and effective method that can transmit h...
