Abstract

A 5.8 G long-distance wireless data transmission system is provided. The system comprises a communication interface circuit, a 5.8 G wireless receiving and transmitting unit, a first high-frequency electronic switch unit, a mode switching control unit, a 5.8 G power amplification unit, a pre-position low-noise amplification unit, a second high-frequency electronic switch unit, an antenna and a power supply unit. data flow is transmitted to the 5.8 G wireless receiving and transmitting unit through the communication interface circuit, and is modulated by the 5.8 G wireless receiving and transmitting unit into a data packet meeting a set format. A pulse signal is generated and sent to the mode switching control unit. The mode switching control unit according to the pulse signal controls the first and second high-frequency electronic switch units to switch into a sending mode or transmitting mode. The power supply unit is used for supplying power to each unit in the system. Beneficial effects of the system are high anti-interference performance and not liable data loss.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a 5.8G long-distance wireless data transmission system. Background technique [0002] When the traditional technology transmits and receives data, the frequency band it uses is in the 2.4G civil frequency band. In this frequency band, both data can be transmitted and data can be received. Because this frequency band is used too frequently, for example: Bluetooth uses the 2.4G frequency band, and wifi also uses the 2.4G frequency band, which will cause the 2.4G frequency band to be dirty. If the UAV uses the 2.4G frequency band, since everyone is using this frequency band, there will be interference, and the packet loss rate will be high virtually. If everyone is using the 2.4G frequency band, sometimes the communication rate and bandwidth will reach Less than that high, retransmit the data after packet loss. For example, the interface bandwidth is 2M. After being disturbed, when...
