Problems solved by technology
[0003] At present, the transmission distance of individual combat wireless image transmission systems is generally within 1km to 5km depending on the environment. If the transmission distance needs to be increased, in addition to increasing the transmission power, the best choice is to increase the relay station, and the relay station is large in size and takes a long time to install. It is unscientific and unreasonable to add such a relay station when the environment is harsh or for emergency communications.

The invention provides an ultralow-delay digital high-definition image relay module of an unmanned aerial vehicle. The ultralow-delay digital high-definition image relay module comprises a power source module, a receiving antenna, a band-pass filter, a COFDM (coded orthogonal frequency division multiplexing) demodulation board, a COFDM modulation board, a linear power amplification module, a transmitting antenna and a control interface board. The receiving antenna is used for receiving spatial wireless signals. The band-pass filter connected with the receiving antenna is used for filtering the wireless signals. The COFDM demodulation board connected with the band-pass filter is used for demodulating digital signals from the wireless signals. The COFDM modulation board connected with the COFDM demodulation is used for generating radio-frequency signals with different frequency bands. The linear power amplification module connected with the COFDM modulation board is used for amplifying the radio-frequency signals. The transmitting antenna connected with the COFDM modulation board is used for transmitting the signals. The control interface board respectively connected with the COFDM demodulation board and the COFDM modulation board is used for setting parameters of the relay module by an external control end. By the ultralow-delay digital high-definition image relay module, the problems such as high difficulty in erecting of relay stations, complex mounting process, difficulty in maintenance and high cost in the prior art are solved; a wireless image transmission system with the relay module is high in transmission image definition, low in transmission delay, high in interference resistance, small in size, low in weight and convenient to use.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to an ultra-low-latency digital high-definition image relay module for drones. Background technique [0002] With the development of wireless communication technology, wireless image transmission system has been widely used in public security, armed police, fire protection, electric power, petroleum, mining, transportation, forest fire prevention, emergency communication and other fields. [0003] At present, the transmission distance of individual combat wireless image transmission systems is generally within 1km to 5km depending on the environment. If the transmission distance needs to be increased, in addition to increasing the transmission power, the best choice is to increase the relay station, and the relay station is large in size and takes a long time to install. It is unscientific and unacceptable to add such a relay station when the environment is harsh or emergency...
