Detailed ways

With reference to the accompanying drawings 1, the utility model will be further described below in conjunction with the accompanying drawings. According to the utility model, the wireless communication relay system for unmanned aerial vehicle power line inspection includes an airborne part and a ground part, and the ground part It includes a ground wireless communication relay station 3, 4, 5 arranged at a given distance for communication with the airborne part and a ground wireless communication relay station set at the UAV flight base 6 for communication with the airborne part and the ground wireless communication relay station. central station.

The given distance can be selected according to the operating distance of the ground wireless communication relay station, or in order to obtain better and more accurate signals, it can be selected according to signal attenuation.

The UAV flight base 6 remotely sends control instructions to the ground wireless communication relay stations 3, 4, and 5 through mobile communication, and executes the start-up or shutdown control instructions. The UAV flight base 6 is connected with the ground command center 7 through a power dedicated optical cable.

Regarding the installation of the ground wireless communication relay station, it is erected on a relatively high transmission line tower through fasteners, such as a tower on a mountain peak, or erected on a transmission line tower at a certain communication distance. Ground wireless communication relay stations use wireless communication or power carrier communication for data interaction.

It also includes a central station constituting the ground command center 7 connected to the central station through wired transmission, which can perform centralized control processing.

In order to improve the accuracy of data transmission and the guarantee of the transmission rate, the wired transmission is optical cable transmission, and it is best to use a special optical cable for electric power for transmission. The more you get to the command center, the larger the amount of transmitted data, so it is best to ensure the transmission bandwidth.

The ground wireless communication relay stations are connected through a wireless transceiver module. The wireless transceiver module is a wireless transceiver module based on a COFDM adjustment mode. COFDM is an abbreviation for coded orthogonal frequency division multiplexing, that is, an abbreviation for coded orthogonal frequency division multiplexing, which is Currently the world's most advanced modulation technology with the greatest development potential. The basic principle is to convert the high-speed data stream into several sub-channels with a lower transmission rate for transmission through serial-to-parallel conversion. It can also send a large amount of data under narrow bandwidth, which is very suitable for wireless transmission, especially this type of adjustment mode.
