There are many security risks in the data exchange of the Internet of Things. Therefore, this paper effectively integrates various technologies to design IoT security access gateway authentication to ensure the secure operation of IoT. The IoT gateway authentication hardware is divided into data collection, processing, access and power supply management modules to improve the security of IoT authentication and the efficiency of data processing. In the software design, the terminal device access identity authentication is realized through the communication protocol, and the identity authentication technology is analyzed to strengthen the security awareness of the network nodes. Test experiments show that in the face of different network problems, it can play a role in ensuring network security access and achieve more convenient, smarter, and more autonomous management.
Route planning is an essential and important part of unmanned aerial vehicle (UAV) operations at sea. Therefore, this paper designs the trajectory planning for autonomous obstacle avoidance of unmanned ships in complex environments. Adopt the body coordinate system and inertial coordinate system to confirm the coordinates and heading angle of the unmanned ship; improve the inertia weight, determine the space constraints of the track planning, and accurately determine the autonomous obstacle avoidance path of the unmanned ship. Simulation experiments show that the trajectory planning method for autonomous obstacle avoidance of unmanned ships in complex environments designed in this paper reduces the time consumption of navigation, has stronger real-time performance, and can approximately represent the global optimal trajectory.
With the construction and continuous growth of the smart grid, the maintenance of traditional manual transmission lines has been gradually replaced by software robots or intelligent equipment for maintenance, and the trend of intelligence and digitization has become increasingly clear. need. This paper analyzes the application of RPA technology in the reconciliation process of material outbound on the power grid, and studies how RPA technology is applied in material reconciliation, helping the power grid to better apply RPA technology.
