Abstract

The invention provides an unmanned ship remote-control unit based on a LoRa technology. The unmanned ship remote-control unit comprises a LoRa module, a micro-control module I, a micro-control module II and a radio frequency antenna, wherein the micro-control module II is interactively connected with the micro-control module I, and data communication is realized through a Uart serial bus; the micro-control module I is interactively connected with the LoRa module, and control for the working mode of the LoRa module and reception for data are realized; the LoRa module is in communication connection with the radio frequency antenna through an acoustic wave amplification circuit; the acoustic wave amplification circuit comprises a surface acoustic wave SAW and a low-noise amplifier LNA. According to the unmanned ship remote-control unit based on the LoRa technology provided by the invention, the communication distance in a water area can reach 2.5 km, and is extremely higher than the water area transmission distance when an unmanned ship remote-control unit in the prior art adopts remote communication of 2.4G frequency band, so that the unmanned ship remote-control unit is low in cost, convenient to operate and low in power consumption.

Description

technical field [0001] The invention relates to the field of remote control of unmanned ships, in particular to a remote control of unmanned ships based on LoRa technology. Background technique [0002] The current remote control design for unmanned ships is generally used for long-distance communication in the 2.4G frequency band. Its transmission distance in waters is about 1km, and the actual transmission distance will reach about 1.5km. Unmanned ships cannot be operated remotely in waters with a distance greater than 1.5km. . [0003] With the development of technology, a LoRa technology is proposed. LaRa means "Long Rang". It is a low-power long-distance wireless communication technology, mainly for applications such as the Internet of Things (IoT) or M2M. Wide area network (LPWAN) is an important wireless technology. LoRa technology has the following advantages: 1. Long distance: In dense urban environments and cities, LoRa base stations or gateways have strong pene...
