Satellite-borne signal transceiving device and method based on Lora technology

Abstract

The invention discloses a satellite-borne signal transceiving device and method based on the Lora technology. The device is installed on a low-orbit satellite. The device comprises a transceiving antenna, a radio frequency coaxial connector, a receiving resonance circuit, a transmitting resonance circuit and a wireless transceiver, wherein the transceiving antenna is connected with the radio frequency coaxial connector; the input end and the output end of the radio frequency coaxial connector are connected with the output end of the transmitting resonance circuit and the input end of the receiving resonance circuit respectively; the output end of the receiving resonance circuit is connected with the wireless transceiver; the input end of the transmitting resonance circuit is connected withthe wireless transceiver; and the wireless transceiver is used for demodulating and modulating Lora signals. According to the satellite-borne signal transceiving device and method based on the Loratechnology, the wireless transceiver is arranged on the low-orbit satellite to transmit and receive the Lora signal transmitted by a ground network, wide-area communication of Lora signals can be achieved, the transmissible area of the Lora signals is enlarged, and the communication range of the Lora Internet of Things system is widened.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an on-board signal transceiving device and a signal transceiving method based on Lora technology. Background technique [0002] Lora technology is based on linear spread spectrum modulation and has the advantages of low power consumption and wide coverage. It is one of the most promising technologies for the development of terrestrial IoT. In recent years, Lora IoT applications have gradually penetrated into daily life, such as shared bicycles, smart homes and smart agriculture. However, when the existing Lora Internet of Things is in use, the transmission of Lora signals needs to be forwarded by equipment such as ground stations. For areas that cannot be covered by the ground network, data exchange with Lora Internet of Things terminals cannot be performed. Contents of the invention [0003] In order to solve the above-mentioned technical problems in th...
