Remote monitoring system and method of drone based on NB-IoT

Abstract

The invention relates to a remote monitoring system and method of a drone based on the NB-IoT. The system comprises a ground control center, a drone and a remote device. The drone comprises a drone body and a first NB-IoT terminal module. The drone body is connected with the first NB-IoT terminal module through a serial port so as to carry out data transmission. The remote device comprises a second NB-IoT terminal module communicating with the first NB-IoT terminal module, a sensor and an executer. According to the invention, by organically combining the drone and the NB-IoT technology, remote monitoring of states of the drone and monitoring of the remote device are achieved.

Description

technical field [0001] The invention relates to the fields of unmanned aerial vehicle technology, sensor technology and intelligent communication technology, and in particular to an NB-IoT-based remote monitoring system and method for unmanned aerial vehicles. Background technique [0002] With the development of technology, the application of drones in various industries has been greatly promoted. As the tasks that UAVs can perform become more diverse, the cost of the corresponding aircraft continues to increase, and the precision sensors on board are expensive and numerous. At the same time, the flight of UAV missions beyond visual range has become the general trend. Such a high-cost aircraft faces three major problems when performing over-the-horizon flight missions: 1. The issuance of ultra-long-distance UAV remote mission control commands and the acquisition of information such as flight status; Mutual coordination; 3. After the accident, the property positioning and ...

Problems solved by technology

However, these communication methods are more commonly used within the line of sight. Once the drone flies more than 2 kilometers, the above communication methods will be interrupted.

Therefore, the existing conventional communication methods have a small coverage area, which greatly limits the working range and application of UAVs.

Adopting the GPRS communication method, although it can realize ultra-long-distance communication, it has three disadvantages: 1. The cost of GPRS is relatively high, and the fee to be paid to the operator is relatively high, which is not conducive to large-scale promotion; 2. GPRS consumes a lot of power. For UAVs flying beyond the line of sight, the rational use of power is very important

However, when GPRS performs continuous communication, the power consumption is high

Once the UAV is lost due to failure and the search time is long, there is no guarantee that the remaining power can support GPRS to continue to work normally; 3. The working mode of GPRS is single, which also makes it difficult to apply the GPRS communication system to UAVs.
