Simulateur de vol de recherche et de sauvetage AUSE-V1

1、But et signification 

---

Le pétrole est une ressource très importante dans la société d’aujourd’hui, et la stabilité des gros équipements dans les usines pétrochimiques et les oléoducs et gazoducs est très importante. L’équipement et les installations de l’usine chimique sont énormes et complexes, fonctionnant dans des conditions de haute température et de haute pression. Ils sont exposés à l’air pendant une longue période et souffrent de la pluie et du vent, ce qui est facile d’avoir de graves accidents de fuite dus au vieillissement, à la corrosion et à d’autres problèmes. Afin d’assurer le fonctionnement normal de l’usine chimique, il est nécessaire d’effectuer les inspections de routine de l’usine chimique et des installations de pipeline afin d’éliminer à temps les dangers cachés de l’équipement et des pipelines. L’inspection de patrouille par drone est la nouvelle technologie d’inspection qui utilise des drones pour transporter d’autres équipements auxiliaires afin d’inspecter les usines chimiques. Il peut compléter efficacement les zones d’inspection de patrouille que l’inspection de patrouille manuelle est difficile ou difficile à atteindre par inspection manuelle. Il améliore considérablement l’efficacité de l’inspection et assure le fonctionnement normal de l’équipement d’installation.

Train the ability of fast recognition and handling of operators to ensure the safety of power usage in the plant area.

4) Formation de base sur les techniques de pilotage

Design basic flight skills training for UAV such as take off, landing, hovering, figure eight flight and four-sided flight route according to relevant forensics and flight operation requirements of key skill points for flight operations to exercise basic flight skills of operators. 

3.4 Recherche sur les facteurs d’impact sur l’environnement et élaboration d’interventions en cas de situation imprévue

Research and develop the impact of unexpected accidents such as electromagnetic interference, meteorological change, and sudden change in wind direction between high-rise buildings in the chemical plant area on UAV and the response strategies and skills of operators. Add the influencing factors (icing, cloudy, sunny, temperature, wind, cloud, rain, snow, fog, GPS failure, collision, etc.) to the patrol inspection scene. Train the response ability of operators in emergency. Study the procedures and elements of chemical plant patrol inspection. Formulate a quality evaluation plan of simulating operation shooting data. So that the staff can master the UAV patrol inspection skills in the training, and comprehensively train the operators from the three aspects of patrol inspection business logic, safety awareness and operation skills to allow them to improve the accident handling ability and business level through practice and ensure the stable and safe operation of chemical plants.
